HYDRAULIC WAVE ENERGY-TO-ELECTRIC ENERGY Russian patent published in 2015 - IPC F03B13/18 

FIELD: electricity.

SUBSTANCE: hydraulic wave energy-to-electric energy is intended to convert wave energy to electric energy. The hydraulic wave energy-to-electric energy comprises frame, rod 3 having cylindrical and helical parts, ellipsoidal float 4, interlock that prevents rotation of rod 3 around vertical axis, body 5 fixed to the frame with rotor 6 placed inside that converts reciprocating movement of rod 3 to rotating movement of rotor 6 and flange 7, whereat magnets 8 are fixed so that they are rotated with rotor 6. Float 4 is represented by elastic corrugated pipe 19 with extension spring 20 inside it, via switching of three-position of electromagnetic distribution valve 14 connected to compressed air source the above pipe may be interconnected with atmosphere through air duct 15 and change its length within limits equal to half of the wave length.

EFFECT: effective electric energy generation is provided due to fast change of the float length up to value equal to half of wave length.
