Problems solved by technology

[0005] However, the motion of a floating wave energy generating device can be decomposed into sub-motions in six directions: sway, surge, heave, yaw, roll, and pitch, and most energy capture units only use one to three of them. The energy of motion is divided, so the efficiency of wave energy capture is not high

Abstract

The invention relates to a closed full-degree-of-freedom wave power generation device and a working method thereof, and belongs to the technical field of wave power generation. The device comprises anupper shell, a lower shell, a hydraulic system, a first energy capturing unit, a second energy capturing unit and a third energy capturing unit. The first energy capturing unit, the second energy capturing unit and the third energy capturing unit are the same in structure and different in mounting orientations, the first energy capturing unit can achieve two degrees of freedom including first movement in an OXZ plane and first rotation in the Y-axis direction. The second energy capturing unit can achieve two degrees of freedom including second movement in the OXY plane and second rotation inthe Z-axis direction, and the third energy capturing unit can achieve two degrees of freedom including third movement in the OYZ plane and third rotation in the X-axis direction. The six-degree-of-freedom energy capturing mechanism is thus integrated, it is guaranteed that the device has high operation reliability, and it can also be guaranteed that the wave energy power generation device has highenergy capturing efficiency.

Description

technical field [0001] The invention relates to a closed-type full-degree-of-freedom wave energy power generation device and a working method thereof, belonging to the technical field of wave energy power generation. Background technique [0002] In order to effectively solve the increasingly serious energy and environmental problems, it has become a global consensus to vigorously develop renewable energy. The ocean, which accounts for 71% of the earth's surface, contains huge reserves of renewable energy, mainly in the form of ocean wind energy, wave energy, tidal energy, temperature difference energy, and salt difference energy. Among them, wave energy is generated by the action of wind, but compared with wind energy, wave energy is more stable and its spatial distribution is relatively concentrated. It is a clean energy with great development prospects. [0003] According to the energy capture method, wave energy conversion devices can be divided into three categories: o...
