Problems solved by technology

[0003] In the above application, although a guide device is also installed on the buoy, in the actual sea trial process, it is found that under the impact of a relatively large wave, the buoy will still deviate significantly
In addition, because the hydraulic transmission mechanism is exposed on the outermost side of the fixed frame, it is directly impacted by the waves, and the piston rod is prone to deviation when moving, which will lead to failure or damage of the hydraulic transmission mechanism, and the output power is very unstable.

Abstract

The invention relates to a combined type oscillation floater wave energy power generation device which comprises a power generation system and a fixing system. The fixing system comprises a snorkeling body, a fixing frame and a working platform, wherein the fixing frame is fixedly connected to the top of the snorkeling body, and the working platform is arranged on the top of the fixing frame. The power generation system comprises floaters, a hydraulic motor and four identical hydraulic transmission mechanisms and an electric generator, wherein each hydraulic transmission mechanism is arranged among three guide rods on each corner of the fixing frame. The floaters are arranged on the four corners of the fixing frame, each corner of the fixing frame is provided with three guide rods to be movably connected with the corresponding floater, and the guide rods are sleeved with the floaters. The hydraulic motor is arranged on the working platform. Each hydraulic transmission mechanism comprises a hydraulic cylinder, an oil pipe and an oil tank, wherein the hydraulic cylinder is located above the corresponding floater, the sleeve end of the hydraulic cylinder is fixedly connected to the corresponding three guide rods through a triangular frame, and a piston rod of the hydraulic cylinder is fixedly connected with the corresponding floater through a fixing disc. The combined type oscillation floater wave energy power generation device can output relatively-stable electric energy and is slightly affected by wave impact.
