Problems solved by technology
The over-wave wave energy conversion device has good output stability and reliability; the disadvantage is that it is huge in size, its fixed structure type depends on special terrain, and the floating structure type has low efficiency
Oscillating buoyant wave energy conversion devices represent the development trend of wave energy conversion devices, and are more suitable for providing energy for small marine unmanned detection equipment working in offshore waters; Its reliability and conversion efficiency still need to be improved

The invention discloses a wave energy conversion device based on bionic fish fins. The wave energy conversion device comprises a heaving floating body and a wave energy absorption and conversion mechanism connected below the heaving floating body. The wave energy absorption and conversion mechanism comprises a generator, a forwards-rotating absorber rotating forwards along with heaving motion of the heaving floating body, and a reversely-rotating absorber rotating reversely along with the heaving motion of the heaving floating body. The forwards-rotating absorber is fixedly connected with a shell of the generator, and the reversely-rotating absorber is connected with a rotating shaft of the generator. The wave energy conversion device has the beneficial effects that the structure is simple, energy absorption and conversion efficiency is high, and the energy requirements of deep and distant sea detection equipment can be met.
Description
technical field [0001] The invention relates to a wave energy conversion device, in particular to a wave energy conversion device based on bionic fish fins. Background technique [0002] As a kind of offshore marine engineering equipment, high-sea detection equipment has been unattended for a long time. Due to the limited energy of its own battery, power supply has always been one of the "bottlenecks" in the development of high-sea detection equipment technology. The nearby use of wave energy to power offshore ocean detection equipment can greatly improve the battery life and reliability of such equipment, especially in the face of relatively scarce wave energy resources in my country's sea areas, to achieve wave energy power supply for small ocean exploration equipment has great practical significance. [0003] A wave energy conversion device is a device that collects wave energy and converts it into electrical or mechanical energy for the grid or special equipment. With t...
