Abstract

The invention discloses a wave energy recovery device and an energy recovery method based on an electrochemical principle, belonging to the technical field of ocean wave energy energy recovery. , the energy recovery mechanism includes a working electrode, a diaphragm and a counter electrode. The working electrode is made of an electric double layer structure material, and the energy recovery mechanism adopts the pressure-induced potential change characteristics of the electric double layer structure material to recover the waves generated by the change of the seawater level. The energy is converted into electric energy, and the energy recovery mechanism obtains the current liquid level change according to the relationship between the power corresponding to the electric energy converted from the wave energy and the corresponding liquid level change and the current power, thereby realizing the real-time recovery of ocean wave energy. The invention can also convert wave energy into electric energy under lower pressure frequency, can recover wave energy lower than the lowest recovery frequency of the existing wave energy recovery device, and widen the recoverable wave frequency range.

Description

technical field [0001] The invention belongs to the technical field of ocean wave energy energy recovery, and more particularly relates to a wave energy recovery device and an energy recovery method based on an electrochemical principle. Background technique [0002] Due to the rapid consumption of non-renewable energy and the environmental pollution and global warming caused by the use of non-renewable resources, the development and application of renewable energy have received extensive attention and have developed rapidly. It has broad application prospects for the recycling of renewable energy. [0003] Ocean energy is a kind of renewable energy attached to seawater. The ocean receives, stores and emits energy through various physical processes. These energy exist in the ocean in the form of tides, waves, temperature differences, salinity gradients, and ocean currents. Among them, wave energy is a very good renewable energy. According to the survey results of the World ...

Problems solved by technology

According to the data, the traditional wave energy generation device based on electromagnetic power generation technology is difficult to effectively generate power under the action of low-frequency and low-amplitude waves. At present, the triboelectric nanogenerator in the frontier field of wave energy recovery in my country recovers wave frequency The range is 0.5-2.5Hz, the maximum output power corresponds to a wave frequency of 1.5Hz, and there are still difficulties in recovering wave energy below 0.5Hz

[0006] The existing relatively stable and efficient wave energy recovery equipment, in order to solve the problem of low energy recovery efficiency, mostly adopts an integrated installation form, which has high maintenance costs and poor resistance to extreme weather. Damping, rectifying equipment, constant pressure equipment and other structures increase the cost and workload of equipment manufacturing, and limit the industrialization and standardized application of wave energy recovery
