The invention relates to the technical field of wave power generation, and discloses a multi-degree-of-freedom swinging wave power generation device. The device comprises a main body frame, a hydraulic power generation assembly and an energy harvesting assembly; four shaft holes are formed in the side face of an annular frame of the main body frame at equal intervals; the hydraulic power generation assembly comprises a claw-shaped push rod, hydraulic pipes, a connector and a power generation main machine; the connector is provided with a main connecting pipe and branch connecting pipes facing the shaft holes; the hydraulic pipes comprise straight pipe sections and arc pipe sections, wherein one ends of the straight pipe sections are connected with the branch connecting pipe, one-way valves are arranged at joints, and the other ends of the straight pipe sections penetrate through the shaft holes and are connected with one ends of the arc pipe sections; the top ends of four claw rod bodies of the claw-shaped push rod are movably inserted into the other ends of the arc pipe sections correspondingly; the power generation main machine is connected with the main connecting pipe; and the energy harvesting assembly comprises a rocker and a floater arranged on the rocker in a penetrating mode, and the top end of the rocker is connected to the connecting center of the claw-shaped push rod. According to the device, wave energy can be converted into hydraulic energy to be used for power generation, the adaptability is high, the energy conversion efficiency is high, the structure is simple, the size is relatively small, and the maintenance is convenient.
Description
technical field [0001] The invention relates to the technical field of wave power generation, in particular to a multi-degree-of-freedom swing wave power generation device. Background technique [0002] The development and exploration of the ocean by human beings is constantly developing towards the deep and distant sea, which also puts forward higher requirements for the corresponding energy supply, and focuses on the development of nearby and clean energy supply methods. As the main component of ocean energy, wave energy has the advantages of high energy density, wide distribution, and long duration. Therefore, the use of wave energy to generate electricity has gradually become an important method of offshore energy supply. [0003] There are many types of wave energy generating devices at present, and their forms, structures, and working principles vary greatly, but most of them are designed for a single wave direction or an idealized wave motion form, and the power gener...
