HYDROGENERATOR OF SEA CURRENTS Russian patent published in 2009 - IPC F03B13/10 

FIELD: power engineering.

SUBSTANCE: hydrogenerator of sea currents comprises two underwater bodies arranged as spindle-shaped and connected to each other as catamaran with a binding compartment. In front part of each body there is a ring of hydrodynamic speed-up installed for water current with confusor, diffuser, working zone, which represents a cylinder outside, and having convex surface inside, arc inwards. Speedup ring in body is installed on pylons, front and back, horizontal and vertical ones. Pylons in section have hydrodynamic profile, front ones act as confusor, back ones - as diffuser, at speed section between front and back pylons there is a blade hydroturbine installed, being coaxially connected to electric generator via step-up planetary reduction gear. Hydroturbines and electric generators of both bodies have opposite rotation. Emergency plant of double purpose is installed in tail part of bodies. Nose cones of bodies and their binding compartment include nose and stern anchor devices with mechanisms for control of length and force of anchor chain tension. Transfer of produced hydrogen and components of electrolysis is done with the help of replaceable transport means.

EFFECT: increased aggregate capacity, efficiency factor and reliability.
