Single-stroke acting chain transmission wave energy conversion device

Abstract

The invention discloses a single-stroke acting chain transmission wave energy conversion device which comprises an oscillating float, a mechanical energy-electric energy conversion device and a floating machine frame. The oscillating float comprises a wave absorbing floating body, a chain fixing device and a guiding device, the mechanical energy-electric energy conversion device comprises a chaintransmission device, a speed-increasing transmission, a one-way coupler, a power generator, a flywheel and an electric control box, the floating machine frame includes a truss main body built by rods,a truss upper platform, a safety floating body, a guide rod, a truss lower platform, a lifting system and a damping counterweight system, the chain transmission device comprises a chain penetrating through the wave absorbing floating body, a load sprocket, a reversing sprocket and a chain tensioning device, one side of the chain is fixed to the oscillating float and transfers and outputs the kinetic energy of the wave absorbing floating body, and the lifting system includes an air compressor, a check valve, a two-position three-way valve, a safety shut-off valve, a lifting pontoon and a connecting pipeline. The floating energy conversion device is simple in structure, stable and reliable, can be lifted and lowered, can resist strong wind and waves, and has the high wave energy utilizationrate.

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. [0003] 1. Chinese invention patent application publication specification CN 101460733 A, international publication WO2007 / 139395 English. 2007.12.6 discloses a device for converting wave energy; Figure 11 As shown (this figure is extracted from the CN 101460733 A specification), the low...

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...
