Description

technical field [0001] The invention relates to the field of ocean energy development and utilization, in particular to a vortex-induced vibration tidal current energy generating device. Background technique [0002] As a relatively easy-to-develop energy form, tidal current energy has been greatly developed in recent years. The energy conversion device is mainly used to convert the kinetic energy generated by the reciprocating motion of seawater caused by the tide into the mechanical energy of the moving parts of the device to drive the generator to generate electricity. At present, the main form of tidal current power generation is hydro turbine. The tidal currents along the coast of my country generally have a relatively small flow velocity and relatively shallow water depth. Since the energy density of tidal energy is proportional to the cube of the flow velocity, the use of water turbines to develop ocean current energy in sea areas with low tidal flow velocity will in...
