Description

technical field

[0001] The invention relates to the field of tidal energy power generation, in particular to a shaftless wave energy power generation device. Background technique

[0002] At present, there are many kinds of existing wave energy generating devices, but there are many problems. The oscillating water column type is driven by an air turbine, and its conversion efficiency is very low when the waves are small. At the same time, its shore-type application usually involves problems such as high engineering cost; the pendulum type technology is suitable for the characteristics of large thrust and low frequency of waves, and the frequency response The range is wide and the energy conversion efficiency is high, but the maintenance of its mechanical and hydraulic systems is relatively difficult. In order to adapt to the harsh marine environment such as typhoons, the emphasis is on ensuring high overall structural reliability and power generation stability, but the devic...
