GENERATOR OPERATING AT SEA CURRENT Russian patent published in 2009 - IPC F03B13/12 F03B7/00 

FIELD: power engineering.

SUBSTANCE: invention is related to designs of plants for transformation of sea current energy into electric energy. Generator that operates at sea current comprises cylindrical jacket 19 with inlet and outlet nozzles 20 and 21, two power generators 1 installed parallel to each other with cylindrical body 3 and external rotor 4, installed outside body 3, and hydrodynamic drive 2, made in the form of blades 9, which are radially installed on external surface of external rotors 4 in both power generators 1. Power generators 1 are arranged as birotating and are equipped with internal rotor 5, installed inside body 3. Internal and external rotors 4 and 5 are connected to each other by means of reduction gear 12, cavity of which is filled with lubricating liquid, which provides for opposite rotation of rotors 4 and 5, and blades 9 are arranged as flat.

EFFECT: invention is aimed at higher efficiency factor of plant with reduction of its dimensions and simultaneous increase of power.
