The invention relates to power plants, in particular hydropower.

Closest to the proposed wave is hydroelectric, containing mounted on the bottom of the reservoir housing of the piston pump, the piston of which is connected with the float, and the discharge pipe is connected through a valve to a storage tank that is connected to the turbine generator.

However, not achieved effective operation of hydroelectric power plants in a wide range of heights of wind waves.

The technical result of the invention is model is.

This is achieved by the fact that hydroelectric power plant equipped with a diaphragm pump, the body of which is combined with the housing of the piston pump to form a unified body, with the discharge line diaphragm pump connected in parallel to the discharge pipe of the piston pump, both pipeline is made elastic. Hydroelectric power is also supplied cable ties connected to the float and a single pump casing.

In Fig. 1 shows a connection diagram of diaphragm and piston pumps to the inlet pipe of the tank; Fig.2 wiring diagram for the connection of cables to the float of Fig.3 scheme of the reservoir, located in the lighthouse tower.

Wave hydroelectric contains suction valves 1 and discharge valves 2 diaphragm pump 3 and the piston pump 4, the sealed chamber 5 for water, flat elastic diaphragm 6, the spring 7 to return the diaphragm to its original position, the piston 8, the spring 9, the guide 10 to the piston rod, the cable 11 to the drive piston 8, the float 12 to the piston 8 of the reciprocating movement and retention on the surface of the water ropes 13, designed for lifting from the bottom of the reservoir a single housing 14 on the OSA 4, storage tank 17, the flexible pipe 19 for supplying water to the tank, turbine generator 19, a projector 20, a flexible discharge pipes 21 and 22 to connect the pump to the pipeline 18.

Wave hydroelectric works as follows.

When the intensity of excitement about one point works effectively diaphragm pump 3, feeding water into the tank 17.

This is because the aperture 6 and the spring 7 is nominally sensitive to hydrostatic pressure from the weight of the waves at one point. At this time, the float 12 POPs up slightly, as between the cavity 16 and the ridge 15 wave height is small, and therefore, the supply pump 4 is negligible.

With increasing intensity of excitement to three or more points float 12 informs the piston 8 of the pump rated reciprocating motion. The supply pump 4 rated. While the cables 13 does not prevent the drive piston 8. The supply pump 3 when three or more points remains nominal.

Thus, the range of wave hydro expands, providing a nominal flow of water in the tank 17 as at the minimum wave height (i.e., up to one point), and in which the winch with cables 13, rise from the bottom of the reservoir housing 14 of the pumps 3 and 4. This slightly distorts the flexible discharge pipes 21 and 22. After maintenance, the housing 14 is lowered to the bottom of the reservoir, and available flexible cables 13 connected to the float 12.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.

EFFECT: wider functional capabilities of a power installation with orthogonal turbines.
