HYDRO-GENERATOR DRIVEN BY SEA CURRENT Russian patent published in 2010 - IPC F03B3/04 F03B13/10 F03B17/06 

FIELD: engines and pumps.

SUBSTANCE: invention relates to designs of plants designed to convert water current energy into electric power. Proposed hydro-generator driven by sea current comprises hydrodynamic drive 2 and electric birotary generator 1 made up of housing 3, outer and inner rotors 4 and 5. Inner rotor 5 is arranged inside said housing 2. Hydrodynamic drive 2 represents blades 9 radially fitted on outer surface of outer rotor 4 and is mounted in casing 19 furnished with inlet and outlet branch popes. Housing 3 and casing 19 represents cylindrical structures. Outer rotor 4 seats outside housing 3. Rotors 4 and 5 are coupled via reduction gear 12 comprising driven gear 13 in mesh with outer rotor 4, idle gears 14 and drive gear 16 in mesh with inner rotor 5 to ensure counter rotation of rotors 4 and 5.

EFFECT: higher efficiency, reduced sizes and increased power output.
