Full-DOF (Degree Of Freedom) wave power generation device

Abstract

The invention provides a full-DOF (Degree Of Freedom) wave power generation device. The full-DOF wave power generation device comprises a float, an oil tank platform, hydraulic rod groups, a support tank body and oil transportation pipes, wherein the float is arranged at the lower side of the oil tank platform; one end of each hydraulic rod group is connected with the oil tank platform, the other end of each hydraulic rod group is connected with the inner side of the support tank body, and the oil tank platform is connected with the hydraulic rod groups through the oil transportation pipes; the hydraulic rod groups comprise a transverse hydraulic rod group and a longitudinal hydraulic rod group; the longitudinal hydraulic rod group is arranged on the oil tank platform in the axial direction, and the transverse hydraulic rod group is arranged on the oil tank platform in the circumferential direction. According to the full-DOF wave power generation device provided by the invention, multiple hydraulic rod groups are adopted, one part of the hydraulic rod groups are circularly arrayed in the horizontal plane, the other part of the hydraulic rod groups are equidistantly arranged in the vertical plane in parallel, and since the motion direction of waves is not determined, the motion of piston rods in cylinder bodies can be caused by motion and rotation, which are caused by the waves, of the float in each direction.

Description

technical field [0001] The present invention relates to ocean wave power generation, in particular to a full-degree-of-freedom 2-3 type ocean wave power generation device. The 2-3 type means that six power generation branch chains are divided into two groups, and each group is equipped with three power generation branch chains. Background technique [0002] The undulating sea is a kind of marine resource, which is pollution-free and has a large storage capacity. According to reports, on the sea surface of 1 square kilometer, there is 200,000 kilowatts of wave motion energy per second. If the wave energy can be well utilized for power generation, it will open up a wider source of energy for human beings, thereby reducing the consumption of other material resources by human beings. [0003] After searching the existing literature, it is found that the patent application number is 201310419252.3, and the name is a kind of wave generator. This invention transfers the energy of...

Problems solved by technology

This invention transfers the energy of the floating body when it descends in the vertical direction to the flywheel of the output shaft through the pulley through the joint action of the floating body and the balance floating body, and then ensures the normal power generation of the permanent magnet synchronous generator on the output shaft through the inertia of the flywheel. The invention has the following disadvantages: the device only utilizes the energy of the floating body when it descends, and does not utilize the energy of the floating body rising and the lateral swing of the ocean waves, resulting in a low utilization rate of ocean wave energy
