Description

technical field [0001] The invention relates to an energy conversion device, in particular to an energy conversion device utilizing ocean wave energy, in particular to a single-stroke work chain drive wave energy conversion device. Background technique [0002] The wave energy is absorbed by the oscillating buoy floating on the water surface, and then the wave energy is converted into mechanical energy through the transmission chain or belt connected to the floating body. The conversion efficiency is high, simple and reliable, and it has been applied; the existing chain transmission There are still some problems in the wave energy conversion device, which need to be improved and perfected.

Problems solved by technology

[0006] The shortcomings of the above-mentioned prior art are summarized as follows: 1. Due to the two tight sides acting on the reversing wheel at the same time, the load is too large and the wear is aggravated; The up and down movement of the oscillating float is unstable; 3. Due to the small number of meshing teeth of the sprocket chain, it causes poor stress and tooth loss, resulting in many faults and difficult maintenance; 4. Due to the large diameter of the column, the resistance to waves is still very large. Therefore, the wave energy conversion efficiency is reduced; the above-mentioned many factors lead to the weakening of the wind and wave resistance and low conversion efficiency of the entire power generation device, and the overall equipment performance declines
