Problems solved by technology

[0004] In early designs, wave power generation devices were mostly integrated into shore-based fixed or offshore base-bottom structures, while fixed structures were mostly suitable for shallow water areas with low wave energy density, and large hydraulic foundations needed to be High-cost investment, which seriously weakens the economic benefits brought by wave energy generation, and limits the practical application and promotion prospects of wave energy utilization

Abstract

The invention relates to an integrated six-degree-of-freedom floater wave energy power generation device. The device comprises a support, a cavity for wave incidence is formed in the support, the side, facing waves, of the support is provided with a head wave perforated plate, the side, away from the waves, of the support is provided with a back wave baffle, and the top of the support is provided with a power generation gear assembly. A floater assembly connected with the power generation gear assembly is arranged in the cavity formed by the support. The floater decouples six types of motion modes into single reciprocating linear motion, the structure is simple, convenient and reasonable, electric energy converted from motion of the floater with all degrees of freedom is collected, wave energy can be fully utilized for power generation, and the power generation efficiency is high.

Description

technical field [0001] The invention relates to the field of wave power generation, in particular to an integrated six-degree-of-freedom float wave power generation device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The ocean is a huge energy pool, and wave energy is an important renewable energy source. However, the spatial distribution of wave energy has certain randomness, how to improve the utilization efficiency of wave energy is the key to the practical application of wave energy power generation. Existing studies have pointed out that integrating wave energy generation devices into structures such as breakwaters, and using the superposition principle of front incident waves and reflected waves of structures such as breakwaters to improve wave energy conversion efficiency. [0004] In early designs, wave power generation devic...
