Abstract

The invention belongs to the technology of new energy resources, relates to a rotary wave energy piezoelectric power generation apparatus which is used for collecting ocean wave energy and converting the ocean wave energy into electric energy. The apparatus is composed of a primary transduction component, an intermediate conversion component, a secondary transduction component and a sealing assembly. The primary transduction component is composed of a damping plate, a slide shaft, a damping plate fastening nut, a floating body, an upper slide sleeve and a lower slide sleeve, an upper balance spring and a lower balance spring, a middle support and a lower support. A broadband rotary piezoelectric generator in the secondary transduction component altogether has six structural forms, wherein arrayed piezoelectric cantilever beams in the broadband rotary piezoelectric generators in different structural forms have different natural frequencies, and thus the frequency bandwidth is relatively wide. The middle conversion component can effectively convert low-frequency linear motion into high-frequency rotation motion, and the power generation efficiency is relatively high. The apparatus is characterized by wide response frequency band and high power generation efficiency, does not need a control system, and can absorb ocean wave energy to the utmost.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a rotary wave energy piezoelectric power generation device, which is used for collecting ocean wave energy and converting it into electric energy. Background technique [0002] Human beings are increasingly monitoring the marine environment and safety, and the energy supply problem of marine wireless sensor network nodes needs to be solved urgently. Traditional energy supply methods include solar energy, lithium batteries, chemical batteries, etc. Solar power generation is easily affected by marine weather; lithium batteries need to be replaced constantly; chemical batteries need to replace electrodes and there is a danger of polluting the environment. Ocean wave energy is a high-quality renewable clean energy with huge reserves. Harvesting wave energy to power ocean wireless sensor network nodes is a very promising way. At present, the main technologies of ocean wave power ge...
