Definitions

  • the technical solution concerns a hydroelectric power plant which can be quickly mounted in the water flow without the need to build a dam.
  • the impeller of the hydroelectric power plant has basically a horizontal axis of rotation and it is placed in a construction which is easily portable. Small hydroelectric power plant is used for flexible mounting in various water flows (or streams) and even for temporary mounting, for humanitarian purposes, and so on.
  • Solution according to DE4313509 requires the production of the solid construction basis, where the impeller with the horizontal axis of rotation is freely placed.
  • solution according to US4104536A1 with impeller which is attached by ropes to the bank (or shore) and which has a fixed height which is set by the legs. This solution, however, requires a constant manual adjustment of the optimal height of submersion. If the impellers are floating, they can be placed in the water flow by means of the ropes, which is a case of publications US4872805 and FR2521223; this, however, requires stably high water level and sufficiently wide water flow; otherwise the impeller will be damaged.
  • impeller in this document denotes a rotating element which transfers the energy of the water to the rotational movement transferred to the electric power generator; it can be called a turbine, a water wheel, a water mill, and so on.
  • the axis of rotation in this text is defined as horizontal means that the axis of rotation of impeller is at least approximately horizontal, but it can deviate from the ideal horizontal position pursuant to the irregularities of mounting of the cage at the bottom of the water flow.
  • the essence of the proposed technical solution lies in the use of a cage with impeller inside. It is preferable if the cage is formed by the traverses distributed in the edges of the cube or rectangle. This helps to achieve a compact outer shape of the device. Side walls and the bottom of the cage can have - but need not to have - a solid filling.
  • the fronts of the cage will be usually without filling; they will be delimited only by traverses on the edges of the front, or they will be delimited by venting draw rods.
  • the water can flow in or out through the fronts without great obstacles.
  • the side walls with the filling can be used to direction the flow of the water through the cage with the impeller. If the side walls are without filling, they will usually have diagonal reinforcements.
  • the lower frame construction can have skids which allow pulling or pushing the cage into desired position during mounting or demounting.
  • the cage will in the preferable arrangement have outer dimensions and shape which correspond to the transportation ISO of the cargo containers (or shipping containers, or intermodal freight containers) in the dimension series from 1 DX to 1AAA.
  • the cage has connecting elements according to particular ISO norm; thanks to this, the whole device can simply be transported by the container carriers on the road or rail or by airplane.
  • the outer container shape of the cage allows simple stacking and storage of small hydroelectric power plants, for example in the standby warehouse.
  • Standardized connection elements designed for connection with the carrier of the containers during transport can be used as a connecting element to anchor the cage to the ground of the water flow, too; it will be, however, preferable if the cage has its own connecting elements which can be used from the top side of the cage.
  • Such connecting elements can be produced by vertically-led pipes in the corners of the cage. Ground screws are inserted to these pipes from above and the screws are drilled and screwed into the ground. The pipes of the connecting elements can reach upward, towards the upper edge of the cage. Thanks to this, the sufficiently long- waisted ground screws can drill into the ground from the above, dry environment.
  • the cage will have width which is smaller than 3,0 m, especially preferably smaller than 2,5 m, which allows for simple road transportation of the cage.
  • the cage is produced by the welded carriers of the cargo container without the inserted fillings - that is, without the bottom, roof, side walls and fronts.
  • the steel construction of the cage is protected against corrosion in the same way the cargo container is.
  • the synergetic effect of the proposed technical solution lies in the fact that large scale production of cargo containers has lowered their production costs and at the same time (taking the possibility of the sea shipping into account) the cargo containers are we 11 -protected against corrosion, which is necessary when the cage is to be inserted to the water flow. It is also possible to use used cargo container - with passed expiration date of the certification - as a cage; such container can no longer be used to transfer goods, but its mechanical features are still sufficient.
  • the advantage of the proposed technical solution is its simple mounting and demounting.
  • Small hydroelectric power plant is carried as a container to the water flow, where it is placed directly onto the spot from the container carrier, or it is placed at the edge of the water flow, whereby it is placed into the water flow by means of a crane. It suffices if there is a short section in the water flow with the sufficiently straight bottom; alternatively, the bottom is adjusted manually or mechanically.
  • the cage can be mounted by the mechanical arm directly from the truck. After the cage is placed into the spot, it is connected to the ground through the connecting element.
  • the ground screws can have a long waist, which will allow them to drill from above, from the level of the upper edge of the cage.
  • Long-waisted ground screws can be on the upper end equipped with openings through which the anchoring rope - or multiple anchoring ropes - is inserted.
  • the anchoring ropes can be connected to ground screws or to the trunks, depending on the local situation.
  • Weights or weight vessels can be used to grip the anchoring rope; the weight vessels can be filled by water or sand. In cases of common water flows the position of the metal cage is stable even without further protection or locking, which is necessary only in case of sudden floods and so on. In cases of expected increase in the water level, the small hydroelectric power plant according to this invention can be quickly demounted and moved to the shore of the water flow.
  • One or more small hydroelectric power plants according to this solution can be placed to the water flow pursuant to its size, width, yield and camber.
  • the cages can be placed side by side throughout the water flow or behind each other in the cascade in the direction of the water flow.
  • the small hydroelectric power plant can be moved to the shore. It is this flexibility which increases the usability of small water flows, since many potential conflicts with the use of the water flow can be solved by the short-term removal of the cage from the profile of the water flow. This also decreases the worries of the persons who have to officially permit the operation of the small hydroelectric power plant.
  • the hydroelectric power plant can be later simply removed from the water flow and transferred elsewhere, or it can be stored - even by means of stacking - in the same way as cargo containers.
  • the impeller is placed on two swing arms.
  • the arms are led from inside alongside the side walls of the cage.
  • the impeller is hollow and it includes a machine room inside it.
  • the impeller is floating, which means that its displacement volume and weight together with the machine room and the weight of the half of the arms are set in such a way that the water lifts the impeller.
  • the impeller led by arms and lifted by water, follows the actual water level at the given place. It is also submersed in the water, whereby the submersion level is in principle always the same, pursuant to the initial setting of the load displacement and the overall weight.
  • This solution can be used in water flows with sufficient water level at the given placed of the water flow; the camber in this realization is not very important.
  • the length of the arms and their allowed angular deviation defines the scope of the acceptable heights of a water level.
  • the arms can have a lower stop which prevents the impeller from impacting on the bottom in case of low water level. This stop is also helpful during the transport, where the position of the impeller should be locked.
  • the performance of the device can be increased if the water flow is directed.
  • a solution has proved to be very effective, where the lower water rectifier is placed below the impeller, whereby the rectifier runs as a float platform from the front part of the cage towards the impeller, whereby the lower water rectifier is in the front part of the cage tiltably placed and it is connected with the arms next to the impeller, whereby the impeller is placed on the arms.
  • the height position of the impeller changes, the position of the lower water rectifier changes too, and there is a similar and stable gap between the lower rectifier and lower part of the impeller.
  • a draw rod can be used on each side of the cage to harness the arms with the flow platform of the lower rectifier.
  • the impeller can be placed in such a way that its shaft is solidly gripped in the side walls of the cage and the position of the impeller during its rotation is stable relative to the cage and relative to the outside environment, too, and the water is led to the impeller from above.
  • the small hydroelectric power plant works as equal-pressure turbine in the same way as Banki turbine.
  • the machine room is placed in the hollow inside of the impeller, that is, the electric power generator with the gear is placed inside the impeller in the same way as in the first type of realization. This achieves the spatially economic construction which does not require a dry machine room in the separate space.
  • such machine rooms are usually designed as buildings above the water level, which is costly and time consuming solution.
  • the vanes of the impeller capture the flowing water; the water runs lower and rotates the impeller and then it flows out through the lower part of the cage - mainly through empty back side of the cage.
  • Rectifiers of the water flow can be placed in the cage; mainly the rectifiers will have a form of the upper inlet trough and the circumferential rectifier.
  • Small hydroelectric power plant with the upper inflow is suitable mainly for small water flows with sufficient camber in the mountain environment, where it is only necessary to dig the basis by the machinery and thereby produce a step in the bottom of the water flow, where the cage is subsequently mounted. The water flow is directed to the upper inlet trough and the small hydroelectric power plant is then capable of operation.
  • the pipes are used for direction of the water to the upper inlet trough.
  • the height of the position of the impeller inside the cage can be adjustable.
  • the shaft of the impeller is then slidably placed on the vertical line in the side walls of the cage. Adjustment of the height adapts the device to the particular conditions of the water flow, mainly to the achieved camber.
  • the impeller is in the fixed height without the need to follow the particular water level of the water flow, and the impeller does not have to be construed as floating, even though - for the reasons of unity - the same floating impeller as in the case of first realization can be used, too.
  • the impeller is produced as hollow, closed body, which on its inside protects waterproofly the power generator and related devices.
  • the technical solution can have an arrangement which combines the features of both previous realizations.
  • the impeller can be floating and mounted on arms whose position can be locked in the stable height. Then the upper inlet trough is attached to the cage and the power plant can operate in the same way as in the second type of the realization with the water flowing in from above. After the arms are released the impeller can work as floating impeller. This makes the construction highly variable.
  • An information module can be part of the small hydroelectric power plant, which involves at least one sensor - for example a water level sensor or GPS position sensor.
  • the gathered data can be sent by the information module to the central in the preset configuration. It can warn before rapidly rising water level, or movement of the cage - which may indicate an effort at theft.
  • Small hydroelectric power plant can be colorful and predominantly green and brown, so it coincides with the environment. Exception should be the strong marking of the forefront of the cage, so the collision of the boats with the construction of the cage is avoided.
  • This small hydroelectric power plant can be used for temporary electric power supply, for example when the camp is created near the water flow, or in cases of humanitarian actions, military actions, and so on.
  • Small hydroelectric power plant is an ecological alternative to engine-powered electric power generators. As opposed to solar and wind power plants - which can be portable, too - it brings about more stable performance without fluctuations in the power supply.
  • this small hydroelectric power plant can be used for long-term operation; mounting multiple cages next to each other or behind each other in the cascade increases the available performance.
  • Small hydroelectric power plant is ecological also because there are no dams and no adverse effects on the life of fish which are related to construction of dams.
