Problems solved by technology
[0003] In the above application, because the hydraulic transmission mechanism is exposed to the outermost side of the power generation device, it is directly impacted by the waves, and the piston rod is prone to deviation when moving, which leads to failure or damage of the hydraulic transmission mechanism, and the output power is very unstable.

Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] As shown in Figure 1, the present invention includes a hydraulic motor 2, a hydraulic cylinder 13, oil pipes and an oil tank 5. The hydraulic cylinder 13 is located above the float 14 of the wave power generation device, the end of the sleeve 12 is fixed by the tripod 11, and the piston rod is fixedly connected with the float 14 of the wave power device through the fixed plate 15; the oil pipes include oil pipe A7, oil pipe B4, and oil pipe C6 , tubing D3, tubing E8, tubing F10 and tubing G9. Oil pipe F10 is connected to oil pipe A7, oil pipe B4, oil tank 5 and oil pipe C6 in sequence, and communicates with hydraulic motor 2; the oil output from hydraulic motor 2 enters hydraulic cylinder 13 through oil pipe D, oil pipe E8 and oil pipe G9 in sequence. The oil pipe F10 and the oil pipe G9 are connected to the oil ports at both ends of the hydraulic cylinder 13...

The invention relates to a hydraulic system of an oscillation buoy wave energy electricity generation device. QI comprises a hydraulic motor, a hydraulic cylinder, oil pipes and an oil tank. The hydraulic cylinder is located above a buoy of the wave electricity generation device. The sleeve end of the hydraulic cylinder is fixed through a triangular support, and a piston rod of the hydraulic cylinder is fixedly connected with the buoy of the wave electricity generation device through a fixing plate. The oil pipes include 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. The oil pipe F sequentially communicates with the oil pipe A, the oil pipe B, the oil tank and the oil pipe C and communicates with the hydraulic motor. Discharged oil of the hydraulic motor sequentially passes through the oil pipe D, the oil pipe E and the oil pipe G and then enters the hydraulic cylinder. The oil pipe F and the oil pipe G communicate with oil openings in the two ends of the hydraulic cylinder correspondingly. Great output force is generated through small drive force; and compared with existing buoy type electricity generation systemsallowing sliding on linear racks to be achieved through motors or allowing hydraulic oil to be replaced with water, the hydraulic system is more economic, more stable, safer and more effective.
