Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, in particular to a wave energy power generation device. Background Art

[0002] Magnetohydrodynamic power generation refers to the technology of converting wave energy into kinetic energy of magnetic fluid, and directly converting it into electrical energy through electromagnetic induction in the power generation channel, which can achieve efficient and clean energy conversion. However, traditional wave energy power generation devices have the disadvantages of low energy capture efficiency and unstable output power.

[0003] In order to solve the above shortcomings, the prior art proposes a wave energy power generation device, which, on the basis of retaining the energy capture mechanism of the original oscillating float type wave energy power generation device, transforms and upgrades the structure of the main float, and innovatively adds 8 auxiliary floats to the main float, so as to increase the wave energy capture amount and improve the wave energy conversion efficiency. While the main float oscillates up and down under the action of waves to drive the magnetofluid in the underwater hydraulic cylinder to generate electricity, the auxiliary float on the main float also oscillates vertically in the reserved groove to achieve two-way capture of wave energy. It uses magnetofluid power generation technology and combines hybrid energy storage for electrical control, which can achieve the effect of smoothing the output power oscillation. Although it is convenient to improve stability and wave energy capture efficiency, the wavelength of ocean waves is different in different weather and environment. It is not convenient to adapt to different wave wavelengths and it is easy to reduce the power generation efficiency. Utility Model Content
