Abstract: The wave generator for a rope-controlled hydraulic cylinder in the present invention includes a Wave Energy Harvest and Conversion system (WEHCS), a rope control device and a gravity anchor. The rope control device includes two members which are controllable in relative motion, i.e., frame and an elongated member. When the frame is located above the elongated member, the top end of the frame serves as a connection point with the WEHCS, and the bottom end of the elongated member serves as a collection point with the gravity anchor; however, when the frame is located below the elongated member, the frame serves as a connection point with the gravity anchor, and the top end of the elongated member serves as, a connection point with the WEHCS. The wave generator is applicable for large waves and adapted to tidal changes, as well as effective in rope-retrieving.

Abstract: The present invention is related to a method and system for wave power generation. When a floating body rises with the wave, a hydraulic cylinder is being pulled to drive a hydraulic motor; the hydraulic motor will in turn drive the generation of power. When a stroke action of the hydraulic cylinder is completed, signals will be transmitted to a drum to release the rope, at which time the hydraulic cylinder will be reset. When the reset is completed, the distance between the floating body and the anchor base increases, the hydraulic cylinder is pulled again, thus repeating the above process. When the floating body drops along with the wave, the hydraulic cylinder is reset at first and then the drum retracts the rope. This system can automatically reset the hydraulic cylinder and do work multiple times during the process of one rising wave.
