Background of the invention

The development and use of energy An engine is still under study and is in the phase of expansion.

At present the existence of some devices and some patents in relation to the subject that it concerns us, but in no case the solutions provided resemble the one described in this report.

Scotland has been the place where they have been most developed studies on the transformation of this type of energy due to the strong waves received by its coasts and the important scientific and industrial infrastructure.

But where an artifact of these characteristics was first installed was in Portugal, (1998). Known as Pelamis (because of its resemblance to a sea snake " pelamis platurus ") it is a floating and flexible device, installed on the high seas and several devices can be connected together and send the electrical energy generated to the shore by means of a long cable

The union between the devices is one of the Weaknesses of this system.

In addition the very existence of the long cable, with the losses that it entails makes its performance not very cash, even considering that thirty joined devices could supply approximately 20,000 households with average European consumption.

As for the patents that can be consider closer to the one in question can be cited two mainly:

D.1.- As the first document we have the patent Thai:

FI2001102620012086 by Rauno Koivusaari Requested in favor of AW-ENERGY OY on October 26 of 2001.

For "Wave power machine".

The described procedure is characterized by use of a plate located at the bottom of a water basin, and boost the plate by the thrust of the waves that are driven by the background, which means a transformation of kinetic energy.

Obviously this procedure has nothing to do with the patent at hand, as we will see later.

       \ vskip1.000000 \ baselineskip
    

D.2.- As a second document we have the patent European following:

E.P-E02770020, for "Un procedure to use wave energy ".

Obviously this procedure does not have nothing to do with the patent at hand, as we will see more late.

There are also certain devices in the phase of experimentation and some others already implemented that define the state of the art, with relation but with notable differences

       \ vskip1.000000 \ baselineskip
    

D.3.- We refer to the devices of "OPT" technology that uses an offshore buoy for the Power Buoy wave generation of the "OPT".

That is not directly related to the recommended invention.

       \ vskip1.000000 \ baselineskip
    

D.4.- We can also cite as antecedent the converter device "Wavedragon" (The dragon of the waves), which is a large floating device, designed to capture and concentrate waves.

The waves climb a ramp to a raised tank through the arms of the platform, there the collected water makes Turn the installed turbines.

Obviously they have nothing to do with it either. system recommended in the invention at hand.

       \ vskip1.000000 \ baselineskip
    

D.5.- And as a last antecedent, we can cite the "Archimedes Wave Swing" device Archimedes "), which is not directly related to the invention that concerns us since it is a large air chamber installed on the bottom of the sea. It obviously does not use the wave Superficial for power generation.

Therefore we have seen that there are varied attempt to use wave force, but all of them different from those recommended in the present invention, which describes a different, more elaborate, better device cheaper performance and maintenance, also being more reliable due to the systems and materials from which it is manufactured, no knowing the applicant's existence today of an invention that is endowed with the characteristics that are described in this report.

Description of the invention

One of the characteristic properties of waves is its ability to travel long distances without hardly any loss of energy, therefore the energy generated in any Part of the ocean ends at the continental edge.

In this way the energy of the waves is concentrated on the coasts which is where the invention that is most effective can be we recommend and whose main characteristics are the following.

The Energy Transformation Device electric power generator that the invention advocates is constituted by the following main sets:

TO.-

Generation buoys set main movement

B.-

Axles and gears set transformation of the main movement into energy electric

C.-

Set of deposits and counterweights of fixing at a certain depth of the entire device.

D.-

Tension and maintenance set Device tension at proper depth.

AND.-

Safety and exit set main power cable

And each of these sets is constituted by the following main elements:

       \ vskip1.000000 \ baselineskip
    

A.- Set of movement generation buoys principal

It is constituted by:

Main motion buoy, consisting of a buoy-floating large and in which that distinguish braking fins, a circular defense for the berth of maintenance and safety vessels, and a mast that sustains a position light. Preferably strobe

This main buoy is the one that moves by impulse of waves and currents and this impulse of translation to be held at the bottom by means of a shackle rotating to a chain fixed to a set of fixed elements, makes that the displacement is transformed into ascensional movement, and said movement is transmitted by means of the chain mentioned to rest of the device

The aforementioned chain behaves near the anchor with the rotating shackle a small buoyancy buoy which helps the main, passing the aforementioned chain for some chain aligners, formed by a sheave attached to the body main by two symmetrical supports and after three sheaves

       \ newpage
    

       \ global \ parskip0.900000 \ baselineskip
    

These three rollers, located in position triangular (its axes) have some with retaining channel, and will move the inner axes of the waterproof case.

After going through these three rollers, the chain goes through another set of aligners alike structure, and ends up joining by means of a rotating shackle to a voltage buoy of smaller size than the main one and in which appreciate a defense ring and below the shackle a thin horizontal plate that serves as a stop against the retainers.

In this way the chain of union between both She is always tense and therefore working, either on the rise or down so that depending on whether it is a movement ascending or descending and of the existence or not of retainers of chain in the sheaves attached to the watertight body, at all times movement is being transmitted to the whole.

Next and in parallel of this set of they can set several sets of generation buoy equipment constituted by a regular size buoy, provided with its shackle swivel and flat stop base from which a chain descends going through a chain aligner the same as before described, then going through three rollers, located of triangular and symmetrical shape as described above, going through another chain aligner similar to those previous and ending in a tension buoy that involves a hoop of defense, a rotating shackle on its bottom and a base flat top.

This set thus described, and that can be expanded to many more sets, it works as follows way:

The continuous movement created by the buoy of generation, by means of the axles and gears that will be described is the section of the waterproof case is transmitted by means of two drive sprockets and a flat inner chain to the axis that moves this set, so that the 1st generation buoy is sinking gradually. When the 1st generation buoy touches the chain aligners by means of the stop plate, a electric clutch, releasing this set and transmitting then the movement to the 2nd generation buoy, until the stop plate of this reaches the corresponding aligners, moment in which this axis is free and begins to transmit the movement to the 3rd generation buoy and so on.

When the axis of the 1st generation buoy remains free, the 1st generation buoy begins to rise, since it has no brake, but does not rise in a violent way, since the form of tension acts as a shock absorber.

In this way the rise of the buoy is continuous and at regular speed. As the free axis of the aforementioned buoy free, clutch the other shaft with the previous one in the stage previous was free, this transmits the movement, already circulating to a centrifugal drive that in turn transmits it to a generator, which it is who through this movement transforms into energy electrical that sends by means of a suitable cable to the outside.

This way the buoy is always working the main one that is responsible for submerging the buoys of generation that with its controlled and continuous ascension generates a constant and continuous movement, which is transmitted to the alternator correspondent.

Once the last generation set is loaded, that is the corresponding generation buoy is found in its most sunken position, the cycle begins with the 1st.

You could say, with the physical caveats corresponding that it is a movement device "almost continuous."

Repeating this cycle continuously, It is what achieves a constant flow of energy.

       \ vskip1.000000 \ baselineskip
    

B.- Set of axles and gears of transformation of the main movement in electrical energy

We have already described in the previous section of general system of movement of the axes that we expand in this pulled apart.

The set of shafts and gears is located located in a waterproof case, which presents on the outside top a safety railing, topped at its ends by a perimeter defense, of rubber or rubber to avoid blows violent of the possible boats that arrive at Device.

This box presents on the outside the rollers described above, each corresponding to an axis with different characteristics that we will see.

We have already described in the previous section of general system of movement of the axes that we expand in this pulled apart.

Rollers with retainer and located in the outside, correspond inside the box with shafts, which they carry a retainer in its part closest to the sheave, standing then a bearing support, a drive pinion, which drags a chain that transmits the rotation to an axis and ends in a support with bearings.

       \ global \ parskip1.000000 \ baselineskip
    

Through the chains, turn is transmitted to the axles with the help of drive pinions.

Then an axis without a sheave is located on the outside, which in addition to the retainer includes a drive pinion, which through the chain transmits the rotation to the drive pinion of the shaft and which also has a bearing support, a clutch, a drive pinion along with another parallel, this pinion by of the tensioned chain, it is related to another drive pinion that Move the other axes.

From this drive pinion is an electronic clutch, the drive shaft, the drive proper, and the generator.

The main axis of the main buoy, in addition has:

.-

A bearing support,

.-

a closing coil,

.-

a clutch,

.-

a bearing support,

.-

a drive pinion,

.-

a drive chain, which connects the drive pinion with the pinion of drag

.-

a drive pinion that moves a shaft

.-

a shaft that moves an alternator,

.-

a alternator that generates electrical energy that is transmitted by,

.-

a cable, which powers a battery,

.-

auxiliary battery device.

C.- Set of deposits and fixing weights to certain depth of the entire device

This set has as its main mission the Device positioning at the desired depth.

It is necessary to keep in mind that the position of Device work is the sunken position at the bottom of the sea so that only the main buoy (a) that is the one that stands out It generates the movement. The rest remains sunk, resting on the seabed where it is supported by the stabilizer element, hydraulic element from which an axis or leg of movement emanates hydraulic, finished at the bottom by a support base.

But it is also necessary to keep in mind that the Device may also need to be moved at the time or simply for maintenance and repair.

Regardless of whether it is almost always possible carry out maintenance work through workers submarines, in other cases, especially when it comes to jobs inside the waterproof case, it is necessary that such work be perform on the surface.

For this the Device has a counterweight, in the lower part thereof, consisting of a rectangular straight parallelepiped formed by metallic elements of High density or by concrete loaded with heavy particles.

Above this counterweight is a flood tank, equipped with an inlet solenoid valve air and a water inlet / outlet solenoid valve.

The flood tank is full of water when the device wants to be fixed at the bottom of the sea. When wants the device to surface, air is introduced compressed by the solenoid valve and the solenoid valve opens, thereby that as the water tank is emptied, it goes ascending to the surface.

The introduction of compressed air into the tank it is done by means of a tube attached to a buoy (g) that has a safety ring and an upper intake of compressed air. When it is necessary to introduce the compressed air to the buoy, a plug pressure hose to the valve.

This ascension is carried out gradually and non-violent due not only to compressed air inlet controlled, but also to the existence of the tension set (D), particularized in the buoy (h).

       \ global \ parskip0.900000 \ baselineskip
    

So that there is no displacement of the set has the help of the chain, conveniently anchored to the bottom by means of a dead man.

Above the flood tank is the waterproof case and above it is anchored to it a safety railing, finished by perimeter defenses, constituted by rubber or rubber elements that will serve as defenses for boats that dock at their sides.

       \ vskip1.000000 \ baselineskip
    

D.- Tension set and tension maintenance of the Device at the right depth

This set consists of a buoy of voltage (h), which involves an upper air inlet valve and Another air outlet valve.

This buoy is attached to the chain or end by means of a rotating shackle to which a free sheave.

This chain / end is at one end. anchored to a lower free sheave, attached to a buried dead, by means of a ring, while the lower sheave is is subject to the dead by means of the ring.

The other end of the chain / end is attached to the outside of the waterproof case by conventional means (ring, knot etc.,).

This simple set allows to maintain the perfectly stable device at the bottom of the sea, with the help of the buoy (h), which depending on the amount and compressed air that have inside it will create a different tension but that said tension will always be to keep it in its correct position.

If the buoy (h) is partially emptied of air, and therefore it exerts less tension pressure down, the whole could scroll up with the help of its buoyancy helped by the tank filled with compressed air.

       \ vskip1.000000 \ baselineskip
    

E.- Safety set and output of the main cable of Energy

The security set consists of a dead, anchored at the bottom of the sea, which involves a ring that holds a chain, attached to the waterproof case by means of a ring.

The length of this chain will be sufficient so that the whole can emerge to the surface, but that once you are in this position you cannot move.

Based on this chain, the cable that moves transmits the electrical energy of the Device to ground.

Preferred Embodiment of the Invention

One of the characteristic properties of waves is its ability to travel long distances without hardly any loss of energy, therefore the energy generated in any Part of the ocean ends at the continental edge.

In this way the energy of the waves is concentrated on the coasts which is where the invention that is most effective can be we recommend and whose main characteristics are the following.

So one or more Devices placed to along the coast can mean a constant and important electric power generation from an inexhaustible and Very cheap wave energy.

The Energy Transformation Device electric power generator that the invention advocates is constituted by the following main sets:

TO.-

Generation buoys set Main movement

B.-

Axles and gears set transformation of the main movement into energy electric

C.-

Set of deposits and counterweights of fixing at a certain depth of the entire device.

D.-

Tension and maintenance set Device tension at proper depth.

AND.-

Safety and exit set main power cable

And each of these sets is constituted by the following main elements:

       \ vskip1.000000 \ baselineskip
    

A.- Set of movement generation buoys principal

It is constituted by:

Main motion buoy (a), consisting of a large floating buoy and in which that distinguish braking fins (3), a circular defense (4) to the docking of maintenance and safety vessels, and a mast (5) that supports a position light (6), preferably strobe

This main buoy is the one that moves through impulse of waves and currents and this impulse of translation to be held at the bottom by means of a shackle swivel (7) to a chain (9) fixed to a set of elements fixed, causes the displacement to become a movement ascending-descending, and said movement is transmitted through the chain (9) cited to the rest of the device.

The chain (9) mentioned above behaves close to the anchor with the rotating shackle (7) a small buoy of buoyancy (8) that helps the main, passing the aforementioned chain (9) by chain aligners (36), formed by a sheave (38) fastened to the main body (36) by two symmetrical supports (37) and then going through three rollers.

These three rollers, (39), (40) and (41) located in triangular position (its axes).

Rollers (39) and (40) have a channel retainer, and will move the shafts (53) and (59) inside the box watertight

The roller (41) has no retainers and is consider as insane turning in both directions, moving the axis (65).

After going through these three rollers (39), (40), and (41), the chain (9) goes through another set of chain aligners (36) of the same structure as the previous ones, and ends by joining by means of a rotating shackle (11) to a buoy of tension (b) of smaller size than the main one and in which appreciate a circular defense ring (10) and below the shackle swivel (11) a thin horizontal plate (12) that serves as a stop against retainers (36).

In this way the chain (9) of union between both buoys, you are always tense and therefore working, either in up or down so that depending on whether it is a upward or downward movement and of the existence or not of chain retainers in the sheaves attached to the watertight body, in every moment movement is being transmitted to the whole.

Next and in parallel of this set of they can set several sets of buoy equipment from generation.

In this case we will consider a simple Field of a set of two buoys.

This set is constituted by paths buoys (c) and (e), of regular size, provided with two rotating shackles (14) and (21) and flat bases (15) and (22) of stop from which the chains (16) and (23) flow down through two chain aligners (36) equal to those previously described.

Then the chain (16) goes through the sheaves (42), (43) and (44).

The three rollers, are located in a way triangular and symmetrical as those described above, moving to then by another chain aligner (36) similar to those above and ending in a tension buoy (d) that involves a circular ring (17) of defense, a rotating shackle (18) in its part bottom and a flat base (19) butt.

Rollers (43) and (44) are retaining, and move the shafts (106) and (110) not so the (42) flat channel, which move the shaft (103).

       \ newpage
    

The continuous movement created by the buoy of generation (a), by means of the axles and gears that are will describe the section of the waterproof case, is transmitted by middle of two drive sprockets and a flat inner chain to the shaft that moves this set, so that the 1st buoy is sinking generation (c) gradually. When the 1st generation buoy (c) it touches the sensors (142) by means of the stop plate (15), it fires an electric clutch (75), releasing this set and then the movement is transmitted to the 2nd generation buoy, until the stop plate (22) of this activates the sensors (143) corresponding, when this axis is free and begins to transmit the movement to the 3rd generation buoy and so successively.

When the axis of the 1st generation buoy remains free, the 1st generation buoy begins to rise, since it has no brake, but does not rise in a violent way, since the tension buoy (d) acts as a shock absorber.

In this way the rise of the buoy is continuous and at regular speed.

With the passage of the chain (16) through the pulleys (43) and (44) since the retaining shaft (43) is free and when remaining free, clutch the other shaft (68) integral with the previous one in the previous stage was in the opposite direction and this transmits the movement, already circulating to a drive pinion (95) that by means of the chain (96) and the drive pinion (97) attached to the shaft (99) transmits the turning power to the maintenance alternator (98), that by means of cable (100), it charges the working battery (101).

This way the buoy is always working main (a) that is the one that is going to submerge the buoys of generation (c) and (e) that with its controlled and continuous ascension they generate a constant and continuous movement, which is transmitted to variator (124) which in turn makes it to the generator (125), where generates the electrical energy that will be sent abroad through the cable (81), process that we will see later.

Once the last generation set is loaded, that is the corresponding generation buoy (e) is is in its most sunken position, the cycle begins with the 1st (C).

You could say, with the physical caveats corresponding that it is a movement device "almost continuous."

Repeating this cycle continuously, It is what achieves a constant flow of energy.

C.- Set of deposits and fixing weights to certain depth of the entire device

This set has as its main mission the Device positioning at the desired depth.

It is necessary to keep in mind that the position of Device work is the sunken position at the bottom of the sea so that only the main buoy (a) that is the one that stands out It generates the movement. The rest remains sunk, resting on the seabed where it is supported by the stabilizer element (90), hydraulic element from which an axis (91) or leg of hydraulic movement, finished at the bottom by a base of support (92).

But it is also necessary to keep in mind that the Device may also need to be moved at the time or simply for maintenance and repair.

Regardless of whether it is almost always possible carry out maintenance work through workers submarines, in other cases, especially when it comes to jobs inside the waterproof case (150), it is necessary that said work be perform on the surface.

       \ newpage
    

For this the Device has a counterweight (89), in the lower part thereof, constituted by a rectangular rectangular parallelepiped formed by metallic elements of High density or by concrete loaded with heavy particles.

Above this counterweight (89) is a flood tank (86), equipped with an inlet solenoid valve of air (87) and a water inlet / outlet solenoid valve (88).

The flood tank (86) is full of water when the device is to be fixed at the bottom of the sea. When you want the Device to surface, it compressed air is introduced through the solenoid valve (87) and the solenoid valve (88), which as the tank is emptied water, it rises to the surface.

The introduction of compressed air into the tank (86) is performed by means of a tube (228) attached to a buoy (g) by middle of a rotating shackle (227) and that has a ring of safety (224) and an upper intake of compressed air (225). When it is necessary to introduce the compressed air to the buoy, a plug pressure hose to the valve (225).

This ascension is carried out gradually and non-violent due not only to compressed air inlet controlled, but also to the existence of the tension set (D), particularized in the buoy (h).

So that there is no displacement of the set has the help of the chain (83), conveniently anchored to the bottom by means of the dead (85).

Above the flood tank (150) is the waterproof case (150) and above it is anchored to the same a safety railing (34), finished by defenses perimetral (35), consisting of rubber or rubber elements that they will serve as defenses for vessels that dock their sides.

D.- Tension set and tension maintenance of the Device at the right depth

This set consists of a buoy of voltage (h), which involves an upper air inlet valve (31) and another air outlet valve (31 ').

This buoy is attached to the chain or cape (30) by means of a rotating shackle (326) to which it is anchored a free sheave (27).

This chain / cape (30), is in a end anchored to a lower free sheave (28), attached to a dead (33) buried, by means of a ring (29), while the lower sheave (28) is subject to the dead by means of the ring (32).

The other end of the chain / end (30) is is attached to the outside of the waterproof case (150) by means conventional (ring, knot etc.,).

This simple set allows to maintain the perfectly stable device at the bottom of the sea, with the help of the buoy (h), which depending on the amount and compressed air that have inside it will create a different tension but that said tension will always be to keep it in its correct position.

If the buoy (h) is partially emptied of air, and therefore it exerts less tension pressure down, the whole could scroll up with the help of its buoyancy helped by the tank (86) filled with compressed air.
