Wave energy power generation device and power generation method

Abstract

The present invention provides a wave energy power generation device and a power generation method. The wave energy power generation device comprises a floating body, a power generation box, power generation array polar plates and an electric energy collecting element; the power generation array pore plates are arranged in the power generation box; the power generation array polar plates comprisea plurality of copper plates and copper columns which are arranged in parallel at intervals; the outer wall of the power generation box is provided with the floating body; the copper plates partiallyimmersed in sea water and the copper columns always immersed in sea water form an array; the power generation box floats on the sea surface through the floating body; and when the power generation boxswings with waves, the areas, wetted by seawater, of the copper plates used as electrodes changes, and thus double electrode layer charge and discharge current is generated and transmitted to an electric energy storage element for storage and output. According to the technical scheme, the problems that in conventional wave energy power generation technologies, moving parts need to be used, low-grade wave energy cannot be collected, and the development cost is high are solved.

Description

technical field [0001] The present invention relates to the technical field of renewable energy power generation, in particular, to a wave energy power generation device and a power generation method. Background technique [0002] Wave energy generation can be divided into two parts: energy harvesting system and energy conversion system. [0003] The function of the acquisition system is to capture wave energy, and its main forms are: oscillating water column type, oscillating float type, pendulum type, duck type, raft type, shrinking channel type, clam type, etc. A wave energy generation system generally includes three stages of energy conversion. The primary conversion system is in direct contact with the waves and captures the wave energy. The energy conversion process is mainly manifested in the conversion of fluid (wave) kinetic energy into mechanical energy, or the conversion of seawater level rise into water potential energy; the secondary energy conversion system pa...
