发明名称 UNDERWATER HYDROELECTRIC STATION
摘要 FIELD: hydraulic power engineering. SUBSTANCE: hydroelectric station has body installed in water stream and divided into compartments. Included in body is inlet converging tube. Successively installed inside body is hydraulic power drive made in the form of bladed turbine with horizontal shaft mounted on bearings, and electric generator. Rotor of electric generator is connected with shaft of hydraulic power drive through two half-couplings. Electric generator is located in hermetic compartment of body. Inlet converging tube is provided with guarding screen. Body compartment with hydraulic power drive has longitudinal outlet holes and deflector of internal water flow made in the form of truncated cone and which is hermetically connected with cylindrical shell. Installed inside shell is horizontal shaft of turbine on bearings. Shaft is provided with end seal which is hermetically connected with cylindrical shell. Tail compartment of body is hermetically sealed and is made in the form of truncated cone. Installed on small base of cone is hermetic waterproof electric connector unit with electric cable. Aforesaid embodiment of underwater hydroelectric station simplifies design and improves waterproofness of its components. EFFECT: higher efficiency. 11 cl, 18 dwg
