Problems solved by technology

The push-and-swing wave power generation device proposed by Muroran Institute of Technology in Japan uses the wave formed by the wave hitting the back wall of the tank and the standing wave formed by the superposition of the wave wave to drive the swing blade to swing, converting the wave energy into mechanical energy and further converting it into Electric energy, the device has a solid structure and a large installed capacity. Compared with the previous structure of the oscillating water column power generation device, there are many problems: (1) the blade structure can only collect energy in one direction, and the efficiency is low (2) the blade structure is not good It can realize energy superposition, (3) the space utilization efficiency is low, the baffle plate energy structure is required, and the structure is relatively complicated (4) it is only suitable for the edge of the coast, and it is not suitable for structures such as drilling platforms

The device has a light structure and is easy to install, but there are many problems: (1) the steel cable layout takes up a lot of space (2) it can only be used offshore (3) the power conversion efficiency is low

[0004] The Chinese invention patent with the patent application number CN201711334949.5 discloses a two-way wave power generation device based on the momentum of ups and downs of waves. The high-speed impact impeller drives the generator to generate electricity, and realizes two high-efficiency electrical conversions of wave energy up and down. However, this invention has some disadvantages: (1) weak anti-pollution ability (2) low power conversion efficiency (3) inefficient Capable of serving offshore drilling platforms
