A controllable attitude wave power generation device based on a linear generator

Abstract

The invention discloses a posture-controllable wave power generation device based on linear power generators and belongs to the technical field of wave energy power generation. The posture-controllable wave power generation device comprises a first power generation mechanism which is vertically arranged. The first power generation mechanism comprises a first buoy, a floating end, the first linear power generator, a stator guiding plate, a guiding shaft, a damping plate, a shaft sleeve and a first guide rail. Wave energy is converted into mechanical energy and then is converted in to electric energy through two stages of energy conversion. According to the posture-controllable wave power generation device, the floating end and the buoy are arranged and move up and down along with waves to drive a first rotor of the first linear power generator to move up and down, so that wave energy is converted into mechanical energy and then is converted into electric energy, only two stages of energy conversion are conducted, and the utilization efficiency of wave energy is improved; meanwhile, the first guide rail is arranged so that the first rotor and a first stator can move relative to each other according to the optimum air gap, vibration loss of the wave energy is reduced, the vibration resistance is improved, and the service life of the power generation device is prolonged.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a controllable attitude wave power generation device based on a linear generator. Background technique [0002] Wave energy power generation uses the energy of waves as the driving force to produce electric energy, and the ocean contains huge energy. How to convert the energy contained in the ocean to the benefit of mankind has become one of the main research topics in recent years. At present, countries around the world have successively researched practical wave energy power generation devices, and some European and American countries have even put them into reality. Although these wave energy generating devices can convert wave energy into mechanical energy and then into electrical energy, these wave energy generating devices have unreasonable structure, large wave energy vibration loss, low wave energy utilization efficiency, and low shock resistance.
