HYDRO-GENERATOR DRIVEN BY SEA CURRENT

摘要

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. ^ 2 cl, 2 dwg
