Problems solved by technology

Due to the randomness and irregularity of the incident wave, the above-mentioned head maintenance mode works better only under the condition of large waves. Therefore, it is widely used in areas with high wave energy flow density in Europe, but in my country, the wave energy period is short and the wave height is high. Overall utilization is lower in small cases
[0004] Application No. 201010575362.5 invention patent discloses a wave-surpassing wave power generation device, which adopts a single-layer structure design, which has poor adaptability to tidal level changes, high requirements for incident wave conditions, and low power generation efficiency
Moreover, it is a floating wave power generation device, which is generally placed in deep water areas. The living environment is extremely harsh, and it is easy to be damaged. The environmental adaptability is low, and installation, deployment and recovery are difficult.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a layered wave-surpassing wave energy power generation device capable of autonomously adapting to changes in tidal range and improving power generation efficiency. Background technique [0002] At present, the high-power shore-based wave energy power station is still dominated by the oscillating water column type. The oscillating water column wave energy power generation device has few underwater moving parts and high device reliability, but its energy conversion efficiency is too low, which can only reach 10% to 15%. %, so the output power of the shore device is difficult to reach a high level. Moreover, due to the limitation of the fixed position, the wave energy utilization rate of the shore-type device is lower than that in the deep water area, and it is also restricted by various factors such as shoreline topography, tidal range and coastal protection. ...
