SEA WAVE ENERGY CONVERTER Russian patent published in 2012 - IPC F03B13/18 

FIELD: power industry.

SUBSTANCE: sea wave energy converter includes upper float 1 located on the water surface, hydraulic cylinder 2 and electric generator with the rotor performing back-and-forth movement, and fixed stator. Rotor consists of constant magnets. Stator includes inductance coils. Hydraulic cylinder 2 is installed inside float 1 and represents a double-acting pump. Converter is equipped with hydraulic vibrator consisting of the cylinder filled with fluid, along the axis of which there arranged with possibility of back-and-forth movement is stepped shaft mechanically connected to generator rotor, and hydraulically through control distributing slide valve to pressure and drain chambers of hydraulic cylinder 2. Vibrator and generator is installed inside pipe 8 connecting hydraulic cylinder 2 to lower float 9, through depth control 12 connected to sea bottom. Float 9 buoyancy is higher than float 1 buoyancy.

EFFECT: higher efficiency of the proposed converter, which is achieved by conversion of low-frequency vibrations of float on sea wave surface to high-frequency vibrations of rotor of linear generator with respect to fixed magnetic conductor.
