Abstract
The utility model relates to a hydraulic system of a vibration float wave power generation device. The hydraulic system comprises a hydraulic motor, a hydraulic cylinder, oil pipes and an oil tank. The hydraulic cylinder is located above a float of the wave power generation device, the casing pipe end of the hydraulic cylinder is fixed through a tripod, and a piston rod of the hydraulic cylinder is fixedly connected with the float of the wave power generation device through a fixing disc. The oil pipes comprise the oil pipe A, the oil pipe B, the oil pipe C, the oil pipe D, the oil pipe E, the oil pipe F and the oil pipe G, wherein the oil pipe F is communicated with the oil pipe A, the oil pipe B and the oil pipe C in sequence and further communicated with the hydraulic motor, oil flowing out of the hydraulic motor enters the hydraulic cylinder through the oil pipe D, the oil pipe E and the oil pipe G in sequence, and the oil pipe F and the oil pipe G are communicated with oil ports in the two ends of the hydraulic cylinder respectively. Due to the fact that great output force is generated through small driving force, compared with an existing float-type power generation system in which a motor slides on a linear rack or hydraulic oil is replaced by water, the hydrocyanic system is more economical, more stable, safer and more effective.
