The invention belongs to the field of marine energy and is designed to extract electrical energy from sea waves, the wind and the liquid column above the turbine.

Known wave power plant comprising a vertical pipe, embedded in the platform, one end of which is open and immersed in the sea, and the other of smaller diameter communicates with the atmosphere, and in the cavity of the pipe is fixed turbine with generator (Wave power Ocean-linx. www.novate.ru/blogs/040309/11568/).

The disadvantage of analog is the inefficient use of compressed air to produce electrical energy.

Closest to the proposed invention is a power plant on the seabed containing a reversible turbine pump with the valve and the generator placed in a chamber mounted on the bottom of the sea, a suction pipe communicating with the sea, a discharge pipe communicating with the receptacle mounted on the bottom of the sea, the top of which is fixed to the pipe, which communicates with the atmosphere (power Plant on the seabed, 2013. http//phys.org/news/2013-05-storage-power-seabed.html).

The disadvantage of the prototype is the high cost of electrical energy for operation of the turbine in the opposite direction when removing water from the tank.

The technical result of the claimed invention is to increase efficiency through use�tion devices for compressing air and exhaust of compressed air, providing forward and reverse movement of sea water from the sea into the tank and from the tank back into the sea.

To achieve the said technical result in the hydropower plant on the seabed containing chamber in which is placed a double acting hydraulic turbine, hydraulic generator, suction and discharge piping and the vessel, mounted on the seabed, additionally mounted a device for compressing air and a device for exhaust of compressed air, a device for compressing air made in the form of a pipeline connecting the hollow column with an inlet valve receiver inlet valve, the valve with the actuator and the container made with sensors maximum and minimum water level, and a device for exhaust of compressed air is made in the form of a pipeline connecting the deflector, the turbine-generator unit, the valve with the actuator and the container on the suction pipe with a removable trash rack and gate valve with electric.

In addition, the claimed solution has optional features that characterize its special cases, namely:

- hollow column made of synthetic material, resistant to salt water and fouling by marine organisms;

- removable trash rack is made in the form of a removable cassette and are made, for example�EP, of copper-Nickel material;

the deflector is made in the form of a cylinder with the rotation unit around a vertical axis, a stabilizer and Windows on the side of the cylinder.

Hydroelectric power plant on the seabed is a complex consisting of surface and underwater structures.

To underwater structures is part of the chamber 1, which includes a turbine 2 double acting, and hydro 3. On the suction line 4 set latch 5 with electric drive, a removable trash rack 6 made in the form of cassettes and manufactured, for example, of copper-Nickel material. Discharge pipe 7 is attached to the vessel 8 with the maximum sensor 9 sensor 10 and minimum water levels. To the vessel 8 is connected a flexible pipe 11 above the bottom of the platform 12 she 13 metal, and is common to devices for compressing air and exhaust of compressed air.

To surface structures is part of the platform 12 mounted on cables with anchors 14 15 16 at the bottom of the sea, on which is placed a device for compressing air and exhaust of compressed air. A device for compression of the air in the form of a conduit 17 connects the hollow column 18, one end of which is open and immersed in the sea, and the other is closed and has an inlet valve 19, the receiver 20 with an inlet valve 21 and the valve 22 with electric. Device for exhaust of compressed air is placed on the metal part of the tube 13, includes: baffle 23 with oslavany 24 around a vertical axis, the turbine-generator unit 25 and the valve 26 with the actuator. The deflector 23 is formed in the shape of a cylinder with the rotation unit 24 around the vertical axis, the stabilizer 27 and Windows 28 on the side surface of the cylinder.

Job hydroelectric plant on the seabed is as follows.

Consider the operation of the device for compressing air in the form of a conduit 17, which is mounted on the platform 12, and with the help of wire 14 is attached to the anchors 15 16 at the bottom of the sea. High wave enters inside the hollow columns 18 and squeezes the air (wave operates as a piston pump), the intake valve 19 is closed, the inlet valve 21 of the receiver 20 is opened, compressed air is accumulated in the receiver 20. In a period of low waves of the inlet valve 21 is closed by the compressed air in the receiver 20, and the exhaust valve 19 is opened under the action of atmospheric pressure that is greater than the discharged pressure in the hollow column 18. Open valves 22 and 5, the compressed air from the receiver 20 enters the tank 8 with the sensors 9 and 10, the maximum and minimum water levels and sea squirts water from the tank 8 through the pressure pipe 7, the water rotates the impeller of the turbine 2, a generator 3 generates electric energy through removable water trash grate 6 flows into the sea.

The process continues until, until the level in�s in the vessel 8 reaches the minimum value, and the signal from the sensor 10 will not close the valve 22 and simultaneously opens the valve 26.

To use the device for exhaust of compressed air. Starting position: valve 5, 22 and 26 with the actuator is closed, the container 8 is filled with atmospheric air. Getting started: the valve 26 is open; the valve 5 is open. Sea water passes through a removable trash grate 6, flows into the suction pipe 4, spins the impeller of the turbine 2, a generator 3 generates electric energy, the water pressure pipe 7 enters the tank 8 and pushes the air through a flexible tube 11 and further on its metal 13 pieces he entered the turbo-generator unit 25, which generates electrical energy, then the air is released into the atmosphere through the window 28 of the baffle 23, which rotates (node 24), automatically guided by the stabilizer 27 towards air flow. When the flow around a cylinder baffle 23 at his window 28 is formed low blood pressure, which increases the efficiency of the process exhaust air. Process air extraction ends when washed by the water level sensor 9 maximum water level, close the valve 5 and the valve 26 with the drives.

The process of compressing air and exhaust of compressed air again and ensure the generation of electrical energy, ISP�lsua pressure energy of the liquid column above the chamber 1 and reproducible wave power and wind power.

The proposed hydroelectric power plant on the sea bottom allows you to eliminate the cost of electrical energy for the operation of a reversible turbine in the opposite direction when removing water from the tank and further to receive electrical energy from a turbogenerator unit fixture for exhaust of compressed air.

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.
