WO2015071788A1 - Multi-windmill - Google Patents

Abstract

This new type of Multi-Windmill has as its function, to produce electricity for the grid, even from very little space. This is in much larger scale compared to conventional wind turbines. This is solved by additional built in generators, and because this new type of wind turbine can be built much bigger and in taller structures, maybe up to skyscraper size of perhaps 500 m high or even higher and bigger, and if possible to compete with other forms of energy. Due to the wind turbine's huge construction size, this type of wind turbine will suit very well as offshore windmills, where at sea it blows more wind speed than on land - up to 50% more. With its stability, it will stand firmly on the seabed / land due to multiple support mast towers. Cross braces that stabilize the turbine against rotations and vibrations makes the turbine stable and solid.

Description

DESCRIPTION

What is already known before the present invention: (The multi-windmill).

This invention is a new type of windmill (Multi-Windmill). What this new windmill involves is indeed already known in other windmills which is, that the new windmill type generates energy from the wind and uses the windmill blades / rotors and the associated gearboxes / generators to convert the wind into electricity. That is, the windmill principle is the same as the ordinary windmills. Windmills are known earlier and are several thousands of years old invention. What is new about the invention:

But what distinguishes this new windmill type (Multi-Windmill) from the ordinary windmills is a drastic design change, but also new technical measures that have never been seen earlier in the windmills, for example, several generators in the same windmill module and 90 degrees gear transmission from rotor, main shaft to generator.

This invention of a new type of windmill called the Multi-Windmill is a kind of mechano set or a kind of Lego function whereby the Multi-Windmill can be built in several variations - and that is not possible with the other windmills that are straight away designed for a specific performance. The multi-windmill has different construction modules that can be built on the basis of different conditions, for example, wind condition, altitude, size and landscape (mainland or seabed). That is, one can, for example, switch and change the number of generators and support pylons of the windmills depending on the conditions. There are different wind conditions on the globe. In some places, the wind blows a lot and constantly and elsewhere, it blows less or intermittently. That means that the Multi-Windmill can be changed to several types of models

Windmill blades / rotors rotating horizontally / transversally constitute another feature in this Multi-Windmill making room for several generators in the tower. The ordinary windmills and their windmill blades rotate diagonally / vertically and can therefore have only one generator and the other types of 3-pylon windmills (other int. Patent applications in the design field) have vertical rotor blades that have not devised the same generator space. Further, this new prototype windmill "Multi- Windmill" can stack its many windmill modules one above the other, so that the windmill is built as building blocks / modules. Only one other windmill has the feature "to build modules one above the other in floors" under the patent WO 2012/023203 Al of NARA Takeshi, Japan. - But this Japanese patent has otherwise no comparisons, since these are two completely different types of windmills in design and construction as I explained in the description to the Danish Patent and Trademarks Office on 14 March 2014. That is, for example, a windmill farm on the sea compels the common windmills to stand spread out over the sea and each one of the many windmills must be individually anchored on the seabed with its own foundation (monopile foundation) across a large area that totally occupies an area of several square kilometres. And as there is a lack of space away from the coasts on account of shipping etc., and countries with only short coastlines like Belgium, Germany, Poland etc., these windmill farms may be a problem - and moreover, possible poor wind conditions in the landscapes. With this new type of Multi-Windmill, one builds only a single foundation with one monopile per pylon, but over an extremely small area of only a few square metres on the seabed / landscape instead of for example, 20 or 30 seabed foundations spread over many square kilometres forming a sea windmill farm. With the new Multi- Windmills, the space is built upward in the air instead of on the ground and therefore exerts less pressure on the marine and the landmass area, because one builds upwards comparable to skyscraper sizes and from the perspective of the landmass, there is better and more wind in the upper strata of air than below near the landmass. - And therefore, all countries on the globe can be involved in building Multi-Windmills.

Ordinary windmills should keep a certain distance from each other in order to not to block the wind from the other windmills. With the new Multi-Windmill, the rotor modules do not block each other as they are mounted one on top of the other in the air.

What technical effect is gained with the invention and comparison with the otherwise known technique for the purpose.

Another 'new' technical effect is, that the Multi-Windmill can transmit its energy to the other generator cabins (mill casings) that are placed in the side pylons / support pylons by means of 90 degrees gear transmission (gear wheel that transfers its energy by 90 degrees).

Furthermore, the rotors are placed horizontally instead of diagonally. That is, one can create more space in the centre stock with the horizontal rotors and

consequently several generators can be built into it. This is the only windmill in the world that incorporates this design and with the additional point that it can generate more electricity. And that is the main patent claim. No other person has claimed this before!

None has even tested whether more energy can be generated from the wind per rotor unit using these new horizontal rotor blades. Maybe they are more effective

75 than the regular rotors as we know them? - There is none who knows and none has experience with this! Perhaps, more "power"-rotation gets transmitted to the gear with the horizontal rotor blades and the blades have an improved energy absorption from the wind, i.e. transmitted by an enormously high gear and improved gearing ratio, because the amount of thrust the blades receive get transmitted by the gearing

80 ratio of the blades is crucial; the gear wheel ratio in normal condition is 9:18 (1:2) - asynchronous generators with, for example, 6 poles will produce an alternating current at 50 Hz that requires 1000 rotations per minute in its high speed shaft. And if the Multi-Windmill can generate higher rotations because the blades have better absorption of thrust from the wind, this will obviously generate more electricity. - If

85 one finds better designed asynchronous generators in the market after this data was released, there will be new generators to choose from, because Multi-Windmill generators need to be enormously large ones.

But there is no doubt that the rotor blades in the new windmill will rotate efficiently and at least as efficiently as the ordinary rotor blades!

90 Multi-Windmill has not been built as a model and tested in a wind tunnel or built as a prototype in practical size. It must be done! And one must start from the beginning like every invention. And that is what this windmill calls for. How can the invention be realised in practice.

95 The invention of this new type of windmill is not something that I can develop and manufacture from my own funds. And therefore, the invention depends on the patent getting sold together with the new Multi-Windmill as design. The sale of the windmill design will take place under a financial collaboration with an already established windmill manufacturer / power supply companies. The patent must find

100 its way into the existing test facilities, factories and capacities of the windmill

manufacturer in order to build this relatively huge Multi-Windmill. As Denmark is the home country of windmills, it is perhaps possible to find a collaborator /

combination of several parties (sponsored by power companies) who can see the opportunity in this invention. There are several windmill companies and factories /

105 power companies in Denmark (possibly state subsidy?). For that matter foreign country, if Denmark has no interest. - But that requires that the state and the windmill companies see the potential in the idea and in the design and that they can envisage building a prototype model.

If I on my own have to describe all the different features down to the minutest 110 details in the product, that will be like that I "myself" have to design all the

architectural engineering structures for, for example, the Great Belt Bridge - all alone? And that would be unfair and absolutely impossible - indefensible!

I must therefore leave certain features in this invention as areas that will be later taken care of by engineers to evaluate each according to their own professional 115 domain. These are, for example, welding, building materials, types of bolts and nuts, what parts should be glued, how should the ramps and elevators be mounted etc. Working environment

Multi-Windmill must be built as per the safety regulations for safe working environment. This means that one should be able to move about in the windmill without risk and danger to one's health. An elevator / lift with transport to the upper floor modules and also internal / external staircases or ladders, in the event of a breakdown of elevator lifts, must be built. One must have the option to walk on the gangways between the girders or on top of the girders with safety balustrades when one has to carry materials from the pylon to the generator cabin in the centre stock over the girder. Safety lanyards are imperative and lift cranes are necessary when major operational measures are taken inside and outside the windmill. This will be a part of the basic principles of the Multi-Windmill to be in compliance with the provisions of safety and working environment. - However, the engineers in safety provisions will implement these principles perfectly in the finished design.

Windmills are environment-friendly and do not emit pollutants!

The project is so large that it must be the person or the company buying and taking over the patent that takes the responsibility for the further processing of the technical details. (DESCRIPTION OF DRAWINGS)

Figure 1.

The Multi-Windmill.

Intro-design as the overall design of the Multi-windmill.

The Multi-Windmill is designed as windmill modules one on top of the other and also 145 consisting of several models. This model consisting of 3 support pylons with cross struts that surround and connect / support the generator cabins with blade rotor consoles in the centre stock constitutes as a whole a windmill tower.

Figures 2, 3 and 4.

Foundation on the seabed.

150 The Multi-Windmill must be built on a foundation on the seabed. It is important that companies specialising in such foundations take the responsibility in deciding how this foundation needs to be built. This foundation must be built with total security!

I have been in the internet and downloaded drawings (copies attached as drawings 2, 3 and 4) that were free and available free of charge on the company homepage. 155 Here, the foundation is shown as support to a single standing pylon tower windmill and the drawings show the procedure for constructing such a windmill foundation / monopile foundation on the seabed.

Figure 5.

The skeletal frame forming generator cabin / mill casing. 160 The generator cabin consists of a skeletal frame like the one in an aircraft construction. The skeletal frame in pure form without cladding. The structure of skeleton shall support the inner modules of the generator cabin.

It is a little difficult to draw the inner supporting cross struts that will fasten, for example, the gearbox, generator etc, because the dimensions of these are not 165 known on the basis of the size of the windmill to be built. But, one must work out a supporting frame within the already drawn skeletal frame in which the gear box and the generator will be mounted.

Again, I do not seek patent claim on the generator module, i.e. the generator itself. This generator module will be handed over to the windmill companies along with 170 this windmill so that they can use their own preferred generators and let their engineers work out the right dimensions for the framework where the assembly of the generator will take place within the cabin / mill casing.

It is also important that the skeletal frame is of such a design that one can assemble and dismantle the parts when they have to be repaired, i.e. one can not only get the 175 whole main shaft or a broken gearbox out of the cabin and mount a new gearbox, but also the sheet metal casing can be dismantled in case large modules have to be mounted / dismantled.

FIG. 1) - Here the fixtures of the skeletal frame are removed. I.e., there is an opening to the generator cabin where the main shaft can be mounted or dismounted.

180 Gearbox and generator and other components can also be mounted / dismounted.

The opening must be used, for example, to get the large main shaft inside or outside the generator cabin. (FIG. 2.) - The generator cabin after its fixtures being mounted so that the cabin can be closed and its box tightened and stability like the support structure of the rotor 185 module and the centre stock.

(FIG. 3, 4, 5, 6) - The brackets that must be mounted in Fig. 1. to close the cabin in Fig. 2. In Fig. 2, these fixtures are mounted and close the cabin.

(FIG. 2) - The generator cabin with the form of the outer sheet metal cladding and marked cross struts.

Figure 7.

Ball bearings associated with the upper and lower parts of the generator cabin.

195 There is the cylindrical part in the upper section of the generator cabin / mill casing and this part must fit into the lower section of the blade console that also has the same cylindrical shape. Since the blade console must spin / rotate around the upper part of the generator cabin, i.e. the main shaft bearing the weight of the blade console, but must also support its weight on the upper part of the generator cabin, it

200 is necessary to use ball bearings both for better rotation and also to avoid friction.

(FIG. 1) .- AXIAL BALL BEARING

(FIG. 2) - Here, it is shown where the ball bearing has to be mounted on the upper ends of the cylinder and the main shaft. The main shaft must be tightly fixed in this bearing in order to remain locked in a fixed position in the generator cabin while at 205 the same time being able to receive the rotations of the blade console and even the rotors.

(The bottom part of the main shaft bottom part is not illustrated in the fixed condition as the main shaft is led down into the gear box. It is the mounting of the gear box that keeps the lower part of the main shaft tight and firm for its rotation 210 and as explained in the drawing 5, 1 wish to let the engineers of the customer work out the exact dimensions for the framework where the assembly of the main shaft with the gear box and the generator will take place within the cabin / mill casing.

The main shaft led into the gearbox is marked only in Fig. 2 drawing 7.

IMPORTANT! - 1 am not seeking patent claim on the framework. However, a few 215 fittings are shown in the drawing 28, but as examples.

(FIG. 3) - Here, the ball bearing is shown in the bottom of the cabin (further, drawing 8) which is fixed to the floor. Here, the separated part of the main shaft is fixed to the lower part of the generator cabin while at the same time this part of the main shaft holds the upper part of the rotor module down firmly and also rotating at the 220 same time. This ball bearing shaft does not transmit its energy to a generator, but is only a fastening mechanism for the rotor module below.

Figure 8.

Ball bearing mounted on the main shaft part. (Shortened main shaft).

This drawing is transferred from the drawing. 7. Fig. 3 is a ball bearing that is 225 designed only to be mounted in the bottom of the generator cabin. The ball bearing mounted on the lower part of the main shaft (that functions as a key) must be guided into the upper keyhole in the blade console (Drawing 11).

The function is to shorten the main shaft so that the main shaft is not connected to a long continuous main shaft - whose Multi-Windmill related function has been 230 explained in other models in other drawings. When the main shaft is shortened, it makes it possible to have a separate blade console module that spins independent of the other blade console rotor modules and that the rotor module takes its own responsibility for the energy supply to its own generator / generators.

Figure 9.

The main shaft. -

240 (Illustrated here as a whole long main shaft for Multi-Windmill with TOP-generator.)

The main shaft is the shaft (support rod) that will connect the generator cabin to the rotor module of the blade console where the blade console rests on top of the main shaft. Where the blade console transmits its rotation to the main shaft. The main shaft must be coupled, clamped, fastened using the keyhole in the key plate module. 245 This will produce a long continuous main shaft through the entire centre stock / Multi-Windmill. This main shaft is specifically for those models of Multi-Windmill that will have a Top-generator.

FIG. 1. - Top and bottom of the main shaft illustrated. This part is important to 250 understand because the upper part of the main shaft must rest or be fixed below or above the axial ball bearing - (drawing 7 and drawing 10. Fig. 1). Ball bearing is screwed, glued, welded as illustrated in Fig. 1 drawing 9.

FIG. 2. - the outer part in each end of the main shaft is shaped like a triangle which will act as a kind of key. This triangle (key) should pass into the keyhole that is also 255 formed as a matching triangle (drawing 11. Fig. 1 and 2. (Drawing 11. but with

shortened main shaft)).

Figure 10.

Generator cabins with extended and shortened main shafts respectively.

In this drawing, you can see the difference between the two different types of shafts 260 that will be mounted in different models of Multi-Windmill.

FIG. 1. - The generator cabin with extended main shaft. This main shaft must be used for the models having Top-generators where a long continuous main shaft through the whole centre stock is required.

FIG. 2. - The generator cabin with shortened main shaft. The feature of having a 265 separated blade console rotor module which spins independent of the other blade console modules.

Figure 11.

Blade rotor - suitable for generator cabins above and below. Blade console's rotor module before it is mounted into the generator cabins.

270 The illustration of drawing 11 is to show how the lower and upper parts of the main shaft of the generator cabin fit into the key hole in the key plate of the rotor module of the blade console.

The blade console (Fig. 2), after it is mounted, must rest on the upper part of ball bearing system of the cylinder in the generator cabin (Fig 3) where the rotor module

275 will rotate. - But at the same time, the generator cabin above (Fig 1.) will use the shortened main shaft key section to guide into the blade console's key hole in the key plate (Fig 2) - This is done without supporting its weight from the generator cabin on top of the blade console. The cross struts marked on the generator cabin will bear most of the weight transferred to the generator cabin without the cabin applying its

280 weight on top of the blade console.

The triangular end pieces of the main shaft should fit precisely into the triangular key hole of the blade console in order to stabilise so that the rotor module does not vibrate during rotation. That is, the rotor module of the blade console sits firmly in the end pieces and the ball bearings both on top and below.

285 Figure 12.

The blades.

Here, the blade console is mounted with ball race (Fig. 1). The ball race of the blade console is important for assembling the ball race on the blade and mount it on the blade console.

I.e., the blades can be made in many different shapes / materials.

Figure 14.

How is the blade console assembled and disassembled into smaller parts.

305 The blade console is designed in order to be assembled from smaller parts. This is so because the rotor module of the blade console should be able to dismantled from the Multi-Windmill itself after it is built. It may happen that one will have to repair and exchange modules and possibly whole floors have to be replaced and therefore it is important that the blade console can be effectively disassembled and removed

310 completely and assembled again in order to be mounted. (FIG. 1.) - Key plate can be disassembled into three smaller parts. - (This part is possibly not be necessary.)

(FIG. 2.) - The inner part of the console can similarly be disassembled into three smaller parts.

315 (FIG. 3.) - The outer part of the console can also be disassembled into three parts. Figure 15.

The outer and inner parts of the blade console assembled.

In order to have the blade console as an assembled unit, the inner part and the outer part must be assembled together so that the bolt holes match each other. It is 320 important that the assemblies in the inner part are staggered assemblies in the outer part. It would be helpful to create a firm gripping and locking mechanism.

(FIG. 1.) - The outer blade console unit that is slightly larger in diameter than the internal blade console (Fig. 2).

(FIG. 2.) - The inner blade console unit.

325 (FIG. 3.) - Here, both console units are assembled and the inner blade console unit is mounted inside the outer blade console unit and fits into the bolt holes.

Figure 16.

The blade console assembled with all its parts including the ball races.

It is important to note here that the assembly of the three parts in the blade console 330 results in a triangular key hole. That is, the notches act as a locking mechanism for the keys from the main shafts of the generator cabins that must be guided firmly into these triangles (key holes).

(FIG. 1.) - Here are the three parts of the blade console from the drawings 14 and 15 assembled into one whole console unit.

335 (FIG. 2.) - the ball race is a part of the blade console here, so that it makes it possible to mount the blades on the blade console - (drawing 12 Fig. 4).

(FIG. 3.) - Bolts screwed in and the parts of the blade console assembled together into one unit. Bolts that are passed through and fastens the assembled console module of the whole blade console. (Refer to drawing 15. Fig. 3 where the bolt holes 340 of the inner blade console holds the outer blade console tightly in a locked grip that keeps the parts firmly fixed to each other.)

It had never been researched earlier into this principle in the windmill technology. And that is required now.

505 (FIG. 1) - The generator cabin is equipped here with one gear transmission system that transmits the energy of the main stock to the cross strut's (FIG. 2) drive shafts - through the cross strut and further into the generator cabins to the generator (FIG. 3). The generator itself (FIG. 1) is not drawn as it is lying below the gear transmission systems.

Here, the Multi-Windmill is illustrated with only one lateral pylon having inbuilt generators in a simple sketch. Some support arms that support and stabilise the lateral pylon and the centre stock against each other from the top and below are mounted, but one can also mount many of these support arms along the tower 540 (drawing 32 Fig. 4).

Figure 35.

Generator cabin without generator.

In this drawing, it is important to understand that the generator cabin in the centre stock does not have a generator. The gear transmission system transmits its rotor 545 energy from the rotor blades of the blade console at 90 degrees through the cross strut into the lateral pylon of the generator cabin. The generator "alone" can find itself in the lateral pylon (drawing 36. Fig. 3)

The generator cabin is supported by four cardan-cross struts extending to the lateral pylons. The drawing further illustrates the floor module in the Multi-Windmill with a total of five generators. Four generators in the lateral pylons and one generator in the centre stock.

585 (FIG. 1) - The generator cabin here is equipped with four sets of gear transmission systems that transmit energy to the drive shafts in the cross strut (Fig. 2) through the cross strut and further into the generator cabins to the generator (Fig. 3).

Figure 40.

Gear.

Here, the gears are illustrated in profile section from top. There is one middle gear 615 (Fig. 1) and three side gears (Fig. 2). The gears are functioning, for instance, in a three-pylon Multi-Windmill, but will be applicable to all Multi-Windmills with gear transmission systems.

The gears are so illustrated because the illustration will be carried further to drawing 42. The function is to decouple one gear (Fig. 3) in drawing 42 from the gear in the 620 middle (Fig. 1) so that the Multi-Windmill will have the option to be able to

dismantle its generators, for instance, in calm weather conditions, where there will be no possibility to drive all the four generators in a three-pylon Multi-Windmill. All generators coupled at the same time in calm weather will be too heavy to drive for the windmill. To ease the rotational pressure and to be able to transmit its rotational 625 power to only one generator, the drive shafts extending from the cross struts to the generators in the lateral pylons can be decoupled. (This is simply shown in drawing 42).

Figure 41.

Hydraulic decoupling of gears.

630 Hydraulic gear will decouple the drive shaft from the gears either with the aid of gear or air pressure "or" by decoupling the outer gear in the gear transmission.

I have outlined this quite primitively and the concept is yet to be further crystallised by the professional experts in hydraulics or engineers in gear technology as to how exactly this is going to work.

635 Decoupling of a gear in the gear transmission would probably be preferable instead of decoupling the whole drive shaft. How exactly should it be designed is hard for me to define. I can imagine that the gear gets decoupled vertically, i.e., upwards rather than horizontally - outwards?

Engineers in gear technology ought to take up the task! There are already over a 640 hundred different solutions based on this principle.

I am not seeking patent claim on the decoupling function, but I have nevertheless illustrated a primitive function for it.

Figure 42.

Generator. 645 Since I do not seek patent claim on the generator, I do not know if I should explain more about the inner functions of the generator. But, since the Danish Patent and Trademarks Office wishes to have a technical explanation of how the functions are related to each other as a whole in the windmill, I have enclosed a drawing of the inner functions of the generator.

650 (FIG. 1).- The main shaft from the blade console is led down to the gear box in the generator cabin from the top.

(FIG. 2).- Disc brakes that adjust / brake the main shaft rotations. This is to ensure that the gear does not overheat and the rotor module does not begin to rotate too speedily.

655 (FIG. 3) .- Gear control lever. (FIG. 4) .- Gear box.

(FIG. 5) .- High speed shaft / drive shaft. (FIG. 6) .- Slip clutch. (FIG. 7).- Generator. 660 (FIG. 8) .- Hydraulic station. (FIG. 9) .- Cables.

The generator is the mechanical function that transforms the rotations of the main shaft / drive shaft rotation into electricity.

Windmill generators are already developed and this Multi-Windmill requires that the 665 generator models of the windmill companies are incorporated in the Multi-Windmill. One can take the existing windmill generators and incorporate them in the Multi- Windmill, but with a little design change.

I do not therefore wish to design a "special" generator for the Multi-Windmill, but recommend buying those that are already there! - In the same way as one wishes to 670 buy a decoupling mechanism for the gears, elevators and lifts etc.

The generator in the Multi-Windmill is an asynchronous generator as in other ordinary windmills, which can transfer its electricity to the power grid.

A gear box receives the rotations of the rotor blades into the gear box via the main shaft whose gear system further transmits the rotations to its high speed shaft / 675 drive shaft that goes into the generator. The gear in the gearbox should have a gear transmission that can rotate several times faster than the main shaft rotations from the rotations of the rotor blades. This requires a gear system with gearing ratio of possibly 9:18 (1:2) or perhaps a different gearing ratio?

The generator with, for example, 6 poles should produce an alternating current of 50 6S0 Hz that will require 1000 revolutions per minute in its high speed shaft transmitted from the gear transmission system. That means that the rotations of the rotor blades in the Multi-Windmill should be able to rotate at least 1000 revolutions per minute at the final stage via the high speed shaft / drive shaft and the gear system in order to produce 50 Hz in its asynchronous generator. And that should not be a hindrance 685 to the capacity of the Multi-Windmill, as it is a giant windmill and also with an

advanced gear system that can generate enormous amount of energy. - All this had long since been developed in the modern windmill generators!

Thus, the drawing 44 is illustrated as the lowest 715 floor, but is otherwise a copy of all the other floor modules. It is in the base of the windmill where the control centre and the electronic management are monitored.

Figure 45.

Multi-Windmill with generators only in the centre stock.

This Multi-Windmill shows the models of the windmill without generators in their 720 support pylons, but only the centre stock has inbuilt generators each in its generator cabin.

This is illustrated in the profile drawing - drawing 46. And as a section drawing from drawing 44. Figure 46. 725 Profile drawing of drawing 45. This drawing is identical to drawing 45 and is one of several different types of models that the Multi-Windmill can be built by means of its mechano-like feature all depending on the modules chosen by the customer.

This model is an easier and cheaper variant that has generator only in the centre 730 stock. That is, the number of generators is limited and the other generators are kept in reserve.

This model is suitable for a smaller scale. Figure 47

Profile drawings of Multi-Windmill with all its possible functions built-in. 735 A clearer overview of how the Multi-Windmill looks in its mechanical transmissions.

(FIG. 1) The TOP generator is illustrated. The TOP-generator is mounted at the top. This means that the main shaft will be connected downward through the centre stock, i.e., the main stock is coupled to the centre stock in order to transmit its total 740 energy from the blade rotors upward to the TOP-generator.

(FIG. 2) - Centre stock generator.

(FIG. 3) - Lateral pylon generator.

FIG. 1. - 2. - 3. assembles all the different generators into one and the same Multi- Windmill. This can result in most feasible and maximum electricity production. If the 745 blade rotor modules generate sufficient rotation to be able to activate all the

generators in the windmill, it is then the technical solution in the sense of Multi- Windmill - and this ought to be possible to be achieved with a large size of the Multi- Windmill placed on the sea with the adjusted wind conditions.

(FIG. 4.) - Main shaft mounted on groove ball bearings secured to the roof of the 750 Multi-Windmill under the Top-generator.

Figure 48.

Design of Multi-Windmill main shaft that is mounted on groove ball bearings on the 755 roof of the centre stock built into the generator cabin.

Here, the groove ball bearing rests on top of the roof of the Multi-Windmill and bears a part of the weight of the main shaft below, (drawing 47. Fig. 4)

The groove ball bearing supports the Multi-Windmill roof inside the Top-generator cabin. The lower part of the groove ball bearing system is secured to the base of the

760 roof. That is, the lower ball bearing system does not rotate, but is firmly anchored to the base and supports the weight of the main shaft and the upper ball bearing system of the ball bearing that rotates coupled with the main shaft and its rotations. It is important that the lower part of the ball bearing system is firmly fixed to the roof and base of the generator cabin without being fixed to the main shaft itself - but

765 that only the upper part of the ball system runs around the firmly fastened main shaft.

The cross struts help to support and bear the weight of the main shaft, so that the entire weight of the main shaft does not exert itself from the top to the base. The ends of the main shaft (mounted ball bearings) in each generator cabin also help to support the weight of the assembled main shaft in the whole centre stock (drawings 9 and 10). Fig. 1). - So the question whether the drawing 48 with the main shaft of the Multi-Windmill mounted on groove ball bearings on the floor and the roof is necessary.- But now, this function is also illustrated for the sake of safety.

Figure 49. Drawing of Multi-Windmill main shaft mounted on groove ball bearings in the floor of the centre stock.

Here is the drawing of the groove ball bearing (cross-section of groove ball bearing) that will be mounted at the bottom of the centre stock and will bear the weight of the main shaft above. It is this drawing that is marked on the drawing 47. Fig. 5 and enlarged to+ on drawing 49.

The question whether the drawing 49 with Multi-Windmill main shaft mounted on groove ball bearing on the floor and roof is necessary

Figure 50.

Cabin without generator and without gear transmission. (FIG. 1.) - Windmill rotor.

(FIG. 2.) - Here is the main shaft without coupling with the generator in the cabin (mill casing). This type of cabin free of the generator and the gear transmission is specially designed for Multi-Windmill with only TOP-generator and no other generator functions either in the lateral pylons or in the centre stock. 790 And this cabinet therefore has no need for construction modules other than the main shaft itself.

Figure 51.

Multi-Windmill with TOP-generators at the bottom, in the middle and at the top.

In this model here, a main shaft is used without coupling with the generator in the 795 cabin (drawing 50 Figure 2.) It creates a long interconnected main shaft through the centre stock of the windmill and connects the Top-generators.

The three lateral pylons have no need for generators and the Top-generators "alone" constitute the generators in the windmill tower.

This is one of the many models of the Multi-Windmill that can be designed. There are 800 several variations that can be built and therefore the Multi-Windmill functions like a kind of mechano set. It is important to understand that there is not only one model in the Multi-Windmill. And as the word "Multi" also indicates, it is a windmill of many possibilities with many models that can be built.

windmill generators - and this illustration is just a simple illustration to show that it is possible to make room for "multiple" generators in the same drive shaft.)

Claims

PATENT CLAIM: (Descriptions of the different patents).

It is the characteristic of this new multiple pylon Multi-Windmill that compels one to make a patent claim is that this Multi-Windmill has never been seen before as the

855 entirety of the elements which it is constituted of. Certain elements from other windmills are recognizable in this Multi-Windmill, but no other windmill has all constituent items put together into a concrete unit as this Multi-Windmill has. No other windmill patents have all the assembled features in one and the same windmill. This Multi-Windmill has these. Furthermore, the Multi-Windmill can be

860 assembled in several variations and several types of models like a kind of mechano- set. Hence the name Multi-Windmill on account of its many variations.

Patent claim 1.

(Drawing 12. Fig. 1, 2, 3 and 4)

The bowl-shaped windmill rotor blades as blade console.

865 The blade consoles fitted with horizontal, thin and elongated bowl-shaped rotor blades are not seen earlier in the windmill industry and will therefore be a case of a new patent claim for these new types of windmills. One can say that the bowl- shaped rotors themselves are not new, as these crop up in other patents too as "vertical" rotors. But this is the first time they are mounted "horizontally" on the

870 blade console in order to provide additional space for more generators and it is the first time that bowl-shaped blades are mounted on a blade console.

The patent claim and what is "characteristic" about it are that these bowl-shaped horizontal rotor blades have ball races mounted on the end of the blade. This feature makes it possible to mount the bowl-shaped horizontal blades on a blade console. 875 When the ball race is mounted on the end of the blade, it is made possible for the blade to be placed horizontally and the blade can therefore be "laid down" (this principle is not seen in other bowl-shaped blade types). When the blade is laid down horizontally, it provides space for the blade to extend longer and capture the wind in a broader radius from the centre of the main shaft. But, in the situation where the

880 blade is mounted on a blade console with approximately the same height as the centre stock, it occupies much less space in the centre stock which again makes it possible to mount several generators in the windmill either in the generator cabins in the centre stock or in the generator cabins in the lateral pylons.

Patent claim 1 is the only patent claim that demands "horizontal" rotors. No other 885 patent is conceived in terms of the "horizontal" rotors. And therefore I seek patent claim for this feature.

The blade console on which the blades are mounted can be broken down.

The patent claim 1 as shown in the drawing 12 (transferred drawings 14 and 15) are the blades mounted on a blade console that can be split and broken down. The

890 additional characteristic of this patent claim 1 is that the blade console can be

broken down into smaller parts. In giant Multi-Windmills where the model is built in huge size, it may necessary to have blade consoles that can be disassembled / assembled in small parts in order to be able to access the inner features of the Windmill, for example, to be able to change a key component or replacement of

895 main shaft or similar. - The technical feasibility thereof is shown in the drawings 14, 15 and 16. The overall feature, the assembled wing console / blade rotor and the total patent claim are put together in drawing 12 Fig. 1, 2, 3 and specially Fig. 4.

Patent claim 2.

900 (Drawing 28)

Gear transmission.

There are no windmills having a 90 degrees energy transmission from the main shaft to drive shaft and further to the generator in the generator cabin in the lateral pylon using the gear transmission and this being further transmitted to several drive shafts 905 using several gear transmissions and further onwards to several generators from the same main shaft with the aid of (Fig 2 transferred to Fig. 3) straight gear and (Fig. 4 transferred to Fig. 5) tapered straight gear.- Drawing 28.

This feature in the drawing 28 is gear transmission with 3 sets of transmission gears (Multi-Windmill can have a different number of transmission gears) transmitted to 910 the generator cabins placed in the lateral pylons. The characteristic and the idea with this gear transmission is that the rotations of the vertical main shaft can transmit its energy at 90 degrees to a horizontally placed drive shaft. (This is a combination of drawings 26 and 27 (seen from top in profile drawing 27.)

This is a new technical solution in the windmill industry and is not seen before in the 915 windmills!

I seek claims patent claim on this technical solution (drawing 28).

Patent claim 3.

(Drawing 35). Multi-Windmill without centre stock generators, but with 90 degree gear 920 transmission / transference.

This cabin illustrated in drawing 35 is designed not to have the generators in its cabin (mill casing) placed in the centre stock. But as drawing 35 shows, the main shaft's rotational energy is transmitted by the type of gear transmission called tapered straight gear to the drive shaft in the cross strut that is further led to the generator 925 cabin in the lateral pylon (this is shown in the profile drawing 36).

Such a cabin and 90 degree gear transmission from the main shaft to the drive shaft in the cross struts are not seen before in other patents.

I seek patent claim on the technical function in the cabin (drawing 35) explained here.

930 Patent claim 4. (Drawing 9)

Main shafts holding the blade console tightly.

I seek patent claim on the technical feature that the end piece (key) of the main shaft formed as a triangle (drawing 9, 10, and 11) fits into the keyhole of the rotor of the 935 blade console that is also formed as a triangular hole (drawing 11 Fig. 2).

By joining the end pieces of the shaft from the underlying cabin (mill casing below) and the shaft from the above lying cabin (mill casing above) together, the blade console is able to rotate independent of friction other than from the coupling of the two main shafts, (shown on the drawing 11).

940 This technical feature is not seen before in other patents. The end piece of the main shaft end (triangular key) can possibly be connected to an extended main shaft (drawing 10 Fig. 1) or to a shortened main shaft (drawing 10 Fig. 2 enlarged and transferred to drawing 8) depending on the model chosen by the developer. The triangular keys (end pieces) should exactly match the dimension and distance into the keyhole of the blade console in order to be firmly fixed and to avoid vibrations.

Main shafts are mounted on ball bearings. Patent claim 5. (Drawing 8.)

Shortened main shaft key mounted on cabin floor.

This shortened main shaft is the "upper" shaft that will hold the rotor unit of the blade console tightly below (refer to Drawing 11 Fig. 1 - 2)

The shortened main shaft (Fig. 1) is mounted on the ball bearing (Fig. 2) which is mounted on a mounting ring washer / taper washers.

The main shaft rotates on the ball bearing without being in contact with the taper washer, while the lower part of the ball bearing is the fastened taper washer.

(FIG. 4) - is the assembled main shaft key.

Patent claim 6. (Drawing 49.)

Support stud / support structure for the main shaft. Here, patent claim is sought for groove ball bearings that will be mounted at the bottom of the centre stock and will bear the weight of the main shaft above.

The technical feature is to serve both as the support stud for the rotating main shaft 965 in the Multi-Windmill and also as the support structure for the main shaft mounted in Multi-Windmill roof / Top-generator cabin - (shown in drawing 47) Fig. 4 and 5).

The technical feature is that the lower ball bearing system does not rotate, but is firmly anchored to the floor (either the floor at the bottom of the Multi-Windmill or the bottom of the floor in the Top-generator cabin, i.e. the roof of the Multi-

970 Windmill), but supports the weight of the upper ball bearing system of the ball bearings mounted on the main shaft rotating along with the coupled main shaft and its rotations. It is important that the lower part of the ball bearing system is firmly fixed to the floor without being fixed to the main shaft itself - but that it is only the upper part of the ball bearing system that runs around the firmly fastened main

975 shaft.

This patent claim implies that all main shafts are coupled to the centre stock and rotate synchronously.

Drawings 47, 48 and 49 should show the technical feature-related explanation. Patent claim 7. 980 (Drawing 1.)

Generator cabins (Mill casings / Nacelles) stacked on top of each other. The design in which all generator cabins stacked on top of the other constitutes a large upright pylon (centre pylon) that becomes a part of the whole windmill tower - Multi-Windmill.

985 The characteristic of this overall technical feature of the generator cabins (mill

casings / nacelles) and rotor modules built on top of each other and simultaneously coupled with each other's generator cabins and with the coupled or individually separated main shafts through the entire centre stock forming a tower has never been seen before in the windmills and must hence remain as clear patent claim.

990 Since the feature of building one on top of the other is by itself an old invention and that NARA Takeshi: Patent no.: WO 2012/023203 Al.- has built a design of a vertical rotor design where the modules can be built on top of each other, I cannot really think of appropriating the same patent for building the windmill modules on top of each other - for that reason alone. One had always built multi-floored buildings for

995 thousands of years!

But, based on Danish Patent and Trademarks Office approval from your letter of 13th February 2014 and on the previously submitted patent application, my patent now lies as claim / approval, but with the demand from you for specific detailed clarifications (that are enclosed here with this new application). But I will not try to

1000 find out if there are other inventions having the same feature of building in floors like Nara Takeshi's patent, because it is Nara Takeshi's patent alone that has this feature of building his modules on top of each other, but he has nothing to do with either bowl-shaped rotors or blade consoles and neither has he anything to do with generator cabins nor with coupled centre stock and coupled main shaft. The patent

1005 claim for this Multi-Windmill stands alone in the patent market based on the material sent from the Danish Patent and Trademarks Office and because Nara Takeshi's windmill as the only other windmill devised in the form of floor modules cannot be compared with my windmill, as his windmill has totally different features than the Multi-Windmill that has totally different features..

1010 But I am making this patent claim on the basis of the design where the generator cabins (mill casings) of the Centre stock are placed on top of each other's modules and it is a patent claim solely based on the design and the technical feature of how the cylindrical form of the blade console and the cylindrical form of the generator cabin are stacked one above the other and for instance, fit into each other's

1015 cylindrical forms and is not seen in others' patents.

This is in fact clarified in Danish Patent and Trademarks Office / Casper Roldsted's letter PA 2013 00651 of 14th March 2014.

That this Multi-Windmill is the only one that has a windmill design that consists of floor modules and also comprises blade consoles and generator cabins (mill casings) 1020 forming a centre stock / windmill tower into one whole tower with no gaps (with and without shortened main shaft, - drawing 10 Fig. 1 and 2) that holds all the console modules tightly with the cabins in a long continuous centre stock, makes this technical feature demand this patent claim under this assumption.

Because this continuous centre stock of the generator cabins together with blade 1025 consoles is not seen earlier in other patents.

That is, I do not seek patent claim for building floors in general, but I do seek patent claim on how the blade console and the generator cabin are coupled together on top of each other and constitute the floors in its design. This technical feature must not certainly be copied.

1030 A patent claim that demands locking the feature and the design, how the windmill looks in its whole as a windmill tower that is not seen earlier in "technical- functional" aspects.

Patent claim 8.

"Multi-windmill" that can be built in several different models.

1035 I seek patent claim on the Multi-Windmill itself as a technical feature in its whole.

That is, I wish to lock the feature and the design of the Multi-Windmill itself as an original patent on account of its feature that it is possible to build several variations and several types of models like some kind of mechano set. - This is not seen before in windmills!

1040 Patent claim on the technical feature that with the Multi-Windmill, one can

interchange its modules and build other modules like some kind of mechano set. That the Multi-Windmill has several variations of different features and designs that can be built. For example, different blade consoles can be selected (drawings 17, 18, 19, 20, 21 etc..) Different numbers of pylons and cross struts can be removed /

1045 mounted. Different numbers of generators are placed at different locations of the lateral pylons or the centre stock either as a TOP-generator or a combination of all three features at the same time.

That is, there are many variations from which the developer can choose on account of the principle that one can remove the modules and the elements and still have 1050 functioning Multi-Windmills - but in different models. Example drawing 1. - drawing 31. - drawing 34. - drawing 37. - drawing 45. - drawings 46 and 47. - And drawing 51.

No other windmill can have this principle!

And that is the technical feature for which I seek patent claim.

1055 Patent claim 9.

"Lateral pylon with multiple generators fitted to the drive shaft".

In this patent claim, the technical solution is to have multiple generators fitted to the drive shaft (the same drive shaft) that is led to the lateral pylon from the 90 degrees gear transmission from the blade console.

1060 The advantage of the patent claim is that when the Multi-Windmill is built in large sizes, the capacity of the generator will be too less for the horse power / Hz. of the blade console. I.e. The blade console of the Multi-Windmill could be built larger than the Hz that the generator can receive and the possibility of building and lifting large generators into the Multi-Windmill Tower can possibly be restricted. - And

1065 therefore, it will require "multiple" generators mounted on the same drive shaft - even if the "multiple" generators are the largest ones available in the market. - And therefore, it is necessary to construct a drive shaft that can accept "multiple" generators.

And these "multiple generators on the same drive shaft is illustrated in the drawings 1070 54, 55, 56 and 57.

The technical solution to add "multiple" generators to the same drive shaft is not seen before in windmill constructions - in any way, not a 90 degrees transmission to the generator cabin of the lateral pylon. - And the Multi-Windmill seeks patent claim under patent claim no.9.

1075 Copies of other international patents including Nara Takeshi's patent have been reviewed in the processing / novelty analysis report of 13th February 2014 by Casper Rolsted of Danish Patent and Trademarks Office. With reference to my application / application number PA 2013 00651. - These are enclosed in your dossier for review, if you wish to go through them once more.

1080 SUMMARY

This new type of Multi-Windmill has as its function, to produce electricity for the grid, even from very little space. This is in much larger scale compared to conventional wind turbines. This is solved by additional built in generators, and because this new type of wind turbine can be built much bigger and in taller 1085 structures, maybe up to skyscraper size of perhaps 500 m high or even higher and bigger, and if possible to compete with other forms of energy. Due to the wind turbine^'s huge construction size, this type of wind turbine will suit very well as offshore windmills, where at sea it blows more wind speed than on land - up to 50% more.

1090

With its stability, it will stand firmly on the seabed / land due to multiple support mast towers. Cross braces that stabilize the turbine against rotations and vibrations makes the turbine stable and solid. I refer to Figure 1
