The invention relates to hydropower, in particular to the submersible hydroelectric power station, capable of transforming the flow of the river into electricity. Known hydropower plant, placed in a stream of small rivers or drop to the bottom, where the flow acting on the blade, which rotates the turbine and transmits the force of rotation to the generator current, most commonly placed on the surface, above the water. For example, patent RU 2166664 C1 Niglihawa, including the device, the endless belt in the form of a chain, rigid vanes mounted on the circuit with drums, pulley chain and pass the blade through the hollow drums.

The disadvantage of analog and the other is the complexity of the whole system in the manufacture and operation, great opportunity in breakdowns of nodes, especially when the hit of extraneous floating objects, the complexity of the removal energy of rotation and transfer it to a generator placed on the frame surface, in General, installation of metal. Difficult operation under the ice. Of course same increase all of the product and the unit of power generated.

Known submersible hydroelectric power station with a vertical location of the working area, comprising a housing with a lateral upper sides, the PTO and generator, rotating drums, blades with floats on the top, mounted on an endless moving elastic ribbon, rotating due to the flow of the water, when this float is made with the possibility of disclosure of the blades in the flow and folding in a counter, the front face of the case is made with the guide edge with the possibility of formation of artificial backwater flow, and between the drums is air-tight compartment (JP 2000087840 And 28.03.2000, F03B 9/00, prototype)

The prototype differs from the stated fact that well-known submersible hydroelectric power station, as similar work in the vertical scheme, i.e. an endless belt with blades arranged vertically. In this working position required fairings for flow direction in the work zone. For placement of generators required special areas over the entire structure. Individual blades in the form of hinged blades represent a complex kinematic structure with multiple relationships and supports, which increases the degree of unreliability.

The invention is a submersible hydroelectric power station with the top location of the working area, comprising a housing with a lateral upper sides, the PTO and generator, rotating drums, blades with floats on the top, mounted on an endless moving elastic ribbon, rotating due to the flow of water when the float is made with the possibility of disclosure of the blades in the flow and folding in a counter, the front face of the case is made with the guide pop the river edge with the possibility of formation of artificial backwater flow, and between the reel is sealed compartment, the blades are made in the form of elastic fabric pockets with roll neck or rigid rotary blades and floats - rotating floating rollers, side upper side is placed at a height level of the rollers, and the sealed compartment made to maintain the tape and placed the PTO and generator.

The invention is illustrated by drawings.

Figure 1 is a side view of the device HPP, immersed in the flow with elastic "pockets" on the tape with the top of the working area.

Figure 2 is an exemplary view of an elastic fabric pocket on the ribbon that is installed on a separate removable element.

Figure 3 - HPP with hard turning vanes in the river or in small artificial channels.

4 is a view of hard turning vanes on the side.

Between the hollow reel (master and slave), mounted on the hull side, stretched elastic endless band made of durable and non-stretchable material, which is fixed to, each other or desynchronization, elastic fabric pockets, or hard turning vanes, with the front open portion of the elastic fabric of the pocket and the upper edge of the rigid rotary blades provided with a torque floating rollers, and in the back pocket, pressed against the tape, there is a cutout for stabilization Karmanov strong flow figure 1 and figure 2. The upper part of the front slant pocket, profile, vertically deflected from the flow direction, and a rigid rotary blade is inclined in the direction of power flow. The angles depend on the flow. For the second (slave) drum stretchy fabric pockets tear with the front shape of the rear end of the body and the floating roller and a rigid rotary blade is folded and pressed a floating roller to the ribbon, but hard turning vanes freely, without the minimum of resistance, pass between the bottom housing and the lower part of the moving endless belt due to the rolling of the floating roller. After the release of elastic fabric pocket or hard turning blades on the leading drum they are filled with the RAM air flow through the front end of the body as a backwater and flow and floating roller, i.e. the number and force of the water, placed in elastic tissue pocket, rotate elastic tape, which in turn rotates the drum. The pressure head in the cavity of hard turning vanes, which is simply rectified at a desired position by means of the floating roller, also affects the endless tape.

Hard turning vanes, and flexible fabric pockets are placed, each in his own type of hydroelectric power station, one after the other or in discord. The capacity of the device depends on the number and sizes of elastic fabric pockets or hard turning blades on the top of the working area of the tape and the distance between the axes of the drums. Between the drums and blades in the form of pockets and shoulder blades on the endless tape is sealed compartment 9, the upper and lower sides of which are supporting guides for the endless belt to prevent it from sagging, while the inner sealed cavity cover 9 can accommodate hydrogenerators and mechanisms PTO, and only the electrical cable connects the device to the shore. On the axes of the drums are placed devices to tension the belt, and they can be automated.

The claimed device operates as follows: the whole body in Assembly with the side flanges is placed in the stream flow or sinks to the bottom of the river, for this device is supplied by the ballast. Drums 2 (master and slave) on the axis 10 are removed from the brake stopper and the endless belt 3 under the influence of water flow on the blade 4 in the form of a rigid rotary blade or elastic fabric pocket starts to rotate. In one of the lateral sides of the body (in a sealed compartment 9) posted reducing the PTO, such as a belt or gears, which transmit force spins the generator, placed in air-tight compartment 9 between the upper and lower parts of an endless belt, and through an electric cable, the energy is transferred to the consumer on the shore.

At the top is m working position of the working area of the endless belt lifting hard turning vanes, and flexible fabric bag is secured floating rotating rollers 6, ie provided quick and full disclosure of hard turning vanes, and flexible fabric pockets in the working area of the endless belt and the folding of these blades in the off position, the counter-current (1, 3, 4.)

The front face 8 of the housing 1 is a backwater, and the shape of the upper edge of the end face 8 contributes to the direction of flow on the blade 4 in the form of elastic fabric pocket or hard of rotary blades (Fig 3, 4.) The lower part of the end face 8 additionally serves as a platform for the weights. Elastic fabric pocket (figure 2) is fixed on three sides of the endless belt or on a separate removable element (2), which can then be placed on the endless belt 3. In the end part of the elastic pocket posted by stabilizing the neck 7, which eliminates the fluctuation of the endless belt 3 in a strong vortex flow or wave. Hard turning vanes (3, 4) is also provided with a floating roller 6, which contributes to the rapid rise of the blades in the upper working position of the ribbon and quick creasing and easy passage of this blade at the bottom of the passive zone, excluding fluctuations in countercurrent. Hard turning vane has a base sector 11, rotating the fastener 5 of the endless belt 3 (figure 4). The angle of the reference sector 11 determines the operating position of the blade in the form of a rigid rotating the blades about the relative flow direction. When the folded position of the blades in a counter reference sector 11, located at the edge of the hard turning vanes, does not prevent the operation of the counter.

Similar HPP with top location of the working area can be placed in the river (if it is small, but fast) multiple products at the same time, blocking her across, thereby creating an additional layer of water, or distributed these hydroelectric power station according to the local conditions of the landscape and the bed of the stream.

Simplicity in the manufacture of hydropower and the use of inexpensive materials available allows the production of even private individuals at home, you only need to purchase the appropriate generators.

The device is very little metal parts, except gearboxes and generators, placed in air-tight compartment 9.

There is a certain simplicity in the calculation of the required capacity and the possible simple increase of the devices in the complex, i.e. scaling as in pepper row in the river, and cascade, one after another, including in the artificial flow constructed parallel to the river.

Easy and "painless" skipped floating objects on top of the lateral edges of the body, and if they reach the rotating parts or blades, easy to go with them, do not harm.

Use any thread and depth not less than the heights of the floating float in the upper position of the rigid rotary blades and elastic pockets (about 90 cm), but if you have to put the product in a smaller depth of flow, it is necessary to make artificial damming or by products to dam up the river, across the current.

There is an opportunity to make the generators outside of the product placed into the stream, for example, through a flexible shaft or to connect several products to a single shaft, then air-tight compartment serves as a ballast. Products are connected sidewalls and ankerwyke, creating a kind of dam the dam of the proposed HPP, but on the same shaft, through which the shaft passes power of rotation to the generator, placed on the shore. Can accommodate groups of products in the indoor, designated from a large river channel, with a given slope of the flow, as an independent power house.

The total capacity of the hydroelectric power plants can reach up to 1000 kW and more, and the cost of 1 kW of not more than 0.5 rubles

The technical result of the invention, is that working hard turning vanes and elastic pockets in HPP with top location of the working area is universal and only the dimensions play a role in the application of various forms of the working tape, to increase the power mechanisms. From the simplicity of the device, respectively, it is possible simplicity and reliability of power plants.
