The mechanical transmission swinging wave power generation device includes a wave energy capture module, an energy conversion module and a swing plate connecting shaft, and the wave energy capture module is connected with the energy conversion module through the swing plate connecting shaft; the wave energy capture module includes a hollow swing plate and a water pump, the water pump is arranged in the hollow swing plate, a water inlet and discharge openingis formed in the hollow swing plate, the water pump is connected with the water inlet and discharge opening, and the water inlet and discharge opening communicates with an inner cavity of the hollowswing plate through the water pump; and the water pump is rotated forward or reversely, and water is injected in the inner cavity of the hollow swing plate or discharged through the water inlet and discharge opening. According to the mechanical transmission swinging wave power generation device with the swing plate density capable of being adjusted, wave energy is converted into energy and the energy is stored, the density of the hollow swing plate is adjusted in real time, the mechanical transmission swinging wave power generation device is adapted to the surrounding wave characteristics, theenergy conversion efficiency is improved, the structure is simple, applicability is high, and promotion is easy.

Description

technical field [0001] The invention relates to the technical field of ocean wave power generation, in particular to a mechanically driven pendulum type wave power generation device with adjustable pendulum plate density. Background technique [0002] China has a continental coastline of 18,000 kilometers long, and the annual available offshore wave energy resources are 249.7TWh[1]. The shape and energy level of waves are affected by the depth of the water. In the area of ​​10-20m in the offshore water depth, there are easy-to-capture oscillating cyclotron waves. The pendulum wave energy generation device is arranged in this area, which can efficiently collect wave energy and transmit it to land for utilization. The pendulum plate used in the existing pendulum wave energy generation device cannot adapt to the large frequency change of nearshore waves, and the energy conversion efficiency is low. The existing pendulum wave energy generation device adopting a hydraulic powe...
