Problems solved by technology

However, the biggest problem with this type of device is that the natural frequency of the energy recovery device is fixed. When the frequency of wave motion changes, the resonance state is destroyed, and the efficiency of energy recovery and power generation of the device becomes very low, thereby reducing the its practical value

Abstract

The invention relates to water surface wave fluctuation energy recovery field, and discloses a resonant water surface wave fluctuation energy recovery device, being suitable for recycling and converting ocean surface wave energy into electrical energy. The resonant water surface wave fluctuation energy recovery device comprises an upper float body which is a cavity body, wherein a wave fluctuation energy recovery unit and a frequency adjustment unit are arranged in the cavity body; in the wave fluctuation energy recovery unit, a magnet does oscillating traverse motion vertical to the axis of the induction coil under the action of water surface wave, and the induction coil moves corresponding to the magnet so as to cut magnetic line of force to generate electricity; the frequency adjustment unit contains a liquid storage tank and an additional liquid tank fixed together with the magnet, the natural vibration frequency of the wave fluctuation energy recovery unit is changed by controlling liquid quality of the additional liquid tank, and the efficiency of the wave fluctuation energy recovery unit is improved by utilizing resonance principle.

Description

technical field [0001] The invention relates to the field of water surface wave energy recovery, in particular to a resonant water surface wave energy recovery device, which is suitable for recovering ocean surface wave energy and converting it into electrical energy. Background technique [0002] Ocean waves contain huge energy, and ocean wave power generation is one of the important research directions in the field of renewable energy technology. Ocean wave power generation uses specific devices to recover the kinetic energy and potential energy contained in waves, and drives generators to generate electrical energy output. It is an inexhaustible energy source. Under the existing technical conditions, ocean wave power generation mainly has the following forms: 1) converting wave energy into air pressure energy to generate electricity. This method uses the ups and downs of waves in the air cavity to alternately generate positive and negative pressures to drive the turbine,...
