The invention relates to hydropower, namely the use of energy tidal flow near the shores of seas, oceans and other large bodies of water by converting it into electricity.

Known tidal hydroelectric power plant, which contains swinging around a horizontal axis, partially submerged blade and located above the level of the water piston pump, the turbine and generator. The blade is kinematically connected with the piston of the pump with the shaft mounted thereon a lever and crank. Pump through pipelines connected to the reservoir and the turbine. Under the action of tidal flow vane is deflected through the shaft, the lever and the crank actuates piston pump. Reverse tidal flow vane is deflected to its original position.

The disadvantage of this device is the complexity of its kinematic scheme and low reliability in operation.

Known also adopted for the prototype tidal hydroelectric power plant (No. 2009367, publ. 10.10.2000, BI No. 28, 2000), containing Anoprienko the blade is installed with the ability to swing about an axis, a piston pump and the turbine (the actuator) with an electric generator, and the vane and piston pump are located under the water level and mounted for oscillation about vertical axes, and the working surface of the blade issue is Lana variable by means of a power cylinder.

The drawback of the power plant is the design complexity, the need for installation of seals on the piston pump and the intermittent feed of fluid to the hydraulic motor associated with the nature of the work piston pump, which makes industrial power generation.

The invention solves the problem of simplifying the construction of hydroelectric power plants, improve the reliability of its work and providing opportunities for industrial power generation.

Required technical result is achieved by the fact that there are hydroelectric containing button under water Anoprienko the blade is installed with the ability to swing around the axis of the hydraulic pump and the hydraulic motor generator, Anoprienko blade invited to perform with the built in its middle part, a hydraulic accumulator and a drain tank, and a hydraulic pump to perform membrane and bilateral. The elastic membrane is proposed to have with external parties Anoprienko blades.

Example run hydroelectric shown in the drawings, in which figure 1 is a perspective view from the side effects of tidal flow; figure 2 - a section a-a figure 1; figure 3 is a simplified hydraulic diagram of the device. In the drawings taken with the following legend:

1 - injection GI is reproved;

2 - hydraulic;

3 - generator;

4 - gidroprovod return of the working fluid;

5 is a cross beam;

6 is a platform for installation of the hydraulic motor and electric generator;

7 is a vertical bearing;

8 - body injection valve;

9 - housing suction valve;

10 - vertical axis;

11 - Anoprienko blade;

12 - shell accumulator drain tank and membrane pumps;

13 - inner wall Anoprienko blades (wall accumulators and waste-holding tank);

14 - hydraulic accumulator cavity;

15 - elastic membrane;

16 - spring;

17 - discharge valve;

18 - cavity membrane pump;

19 - drain tank;

20 - foot valve.

Hydroelectric power plant consists of two reinforced in the surf zone at some distance from each other (figure 1) vertical supports 7, interconnected by two transverse beams 5 and a platform 6 for installation of the hydraulic motor 2 generator 3. On the beams 5 attached Anoprienko the blade 11 can swing in a certain range around the vertical axis 10.

Anoprienko the blade 11 includes a shell 12 (figure 2) with a fixed inner walls 13 forming with the shell cavity of the accumulator 14 and the drain tank 19, separated by a horizontal partition (n is the drawing shows but not marked). External wall Anoprienko the blade 11 is made in the form of an elastic membrane 15 diaphragm pump. Elastic membrane 15 can be made with springs 16, which gives them additional firmness, or without them. The inner wall 13 Anoprienko blades 11 and the external elastic membrane 15 to form the cavity 18 of the membrane pump. Intake 20 and the discharge valves 17 can be placed on the inner walls 13 (figure 2)and the ring 12 in special housings 8, 9 (figure 1). The second option is preferable, as it allows a quick replacement of the valves.

Hydroelectric works in the following way. When exposed to tidal flow on the left membrane 15 (figure 2), it bends toward the inner rigid wall 13, the discharge valve 17 is opened and the working fluid from the cavity 18 of the left diaphragm pump is supplied under pressure in the accumulator 14, where the discharge hydrobromide 1 is fed to the hydraulic motor 2, the rotation shaft which is transmitted to the generator 3. The working fluid in hydrobromide 4 merges into the tank 19. At the same time, right membrane 15 is bent by the forces of elasticity in the direction opposite to the wall 13, the suction valve 20 is opened, the discharge valve 17 is closed and the working fluid from the tank 19 fills the cavity 18 of the rights of the th membrane pump. When exposed to the sliding wave tidal stream right diaphragm pump works by forcing left on the skin.

Increased pressure in the gas cavity of the hydraulic accumulator 14 (R>Ratadjusts the flow of operating fluid to the hydraulic motor 2, which provides a uniform work, as well as stable operation of the generator 2.

It is the implementation of hydropower as a single unit, including Anoprienko blade, two diaphragm pump, a hydraulic accumulator and the drain tank makes the construction of the simplest and most adapted to the perception of the energy tidal stream and convert it into pressure energy of the working fluid and then into electricity.

Tidal hydroelectric containing Anoprienko the blade is installed with the ability to swing around the axis of the hydraulic pump and the hydraulic motor generator, wherein Anoprienko the blade is made with built in its middle part, a hydraulic accumulator and a drain tank, and the hydraulic pump is made of membrane and bilateral, and the elastic membrane are with external parties Anoprienko blades.
