Abstract

The invention discloses a multi-degree-of-freedom energy harvesting closed type wave energy power generation device. The first base frame, the second base frame, the third base frame and the gear rack mechanism are installed in the outer floating body in a sealed mode, and the outer floating body floats on the sea surface. The gear and rack mechanism is coaxially and fixedly installed in the middle of the third base frame, the third base frame is coaxially and movably installed in the middle of the annular second base frame, the second base frame is coaxially and movably installed in the middle of the annular first base frame and movably connected to the inner wall of the outer floating body, and the first base frame is fixedly connected with the inner wall of the outer floating body. Wave energy on multiple degrees of freedom can be converted into electric energy, a totally-closed design mode is adopted, the environment adaptability is high, and the energy conversion efficiency is high.

Description

technical field [0001] The invention relates to a power generation device, in particular to a closed-type wave energy power generation device that captures energy with multiple degrees of freedom. Background technique [0002] The multi-degree-of-freedom wave energy device is a power generation device that can simultaneously absorb wave energy in multiple degrees of freedom. my country's coastal waves have obvious broad-spectrum characteristics, which pose a high challenge to wave energy capture. The traditional single-degree-of-freedom wave energy device based on spectral peak frequency design has low capture efficiency, which leads to a bottleneck in development. The energy harvester of the multi-degree-of-freedom wave energy device should have the advantages of multi-direction, wide-frequency response energy absorption, and adapt to the characteristics of wide-spectrum wave energy resources. The multi-degree-of-freedom wave energy device generally releases three or more...
