Abstract

Disclosed is a wave-power generation system. The system includes a stationary frame, a float structure installed to the stationary frame, a rotary shaft coupled to a generator and rotatably installed to the stationary frame, a rotary drive coupled to the rotary shaft of the generator via a one-way clutch, a three-node link rotatably installed at a point P of the stationary frame, a float installed to one end of the three-node link, a rope having one end coupled to the other end of the three-node link and the other end wound around the rotary drive, a flywheel installed to the rotary shaft, and a resiliently recovering member having one end coupled to the stationary frame and the other end coupled to the rotary drive.
