SEABED HYDROELECTRIC POWER STATION Russian patent published in 2015 - IPC F03B13/22 

FIELD: power industry.

SUBSTANCE: hydroelectric power station comprises a chamber 1 which houses a bilateral hydraulic turbine 2, a hydrogenerator 3, suction and pressure pipelines 4 and 7 and a vessel 8 installed at the seabed 16. Also the air compression device and the compressed air extract device are mounted. The air compression device is designed as a pipeline 17 connecting a hollow column 18 with the inlet valve 19, a receiver 20 to the input valve 21, a gate valve 22 to the electric drive, the metal pipe 13 placed in a platform cavity 12, a flexible pipe 11 and a vessel 8 designed with maximum and minimum water level sensors 9 and 10. The compressed air extract device contains a deflector 23, the metal pipe 13 placed above a platform 12, the turbo-generator unit 25, the gate valve 26 with the electric drive, the metal pipe 13 placed in the platform cavity 12 and the vessel 8. On the pipeline 4 the removable baffle lattice 6 and the gate valve 5 with the electric drive are installed.

EFFECT: improvement of efficiency due to the use of fixtures for air compression and compressed air extract providing the direct and return movement of sea water from the sea into vessels and back to the sea.
