Underwater rotary type piezoelectric power generation device

Abstract

The invention discloses an underwater rotary type piezoelectric power generation device, and belongs to the technical field of new energy sources. The underwater rotary type piezoelectric power generation device is particularly suitable for converting collected kinetic energy generated by flowing of water particles in rivers or oceans into electric power. The underwater rotary type piezoelectric power generation device is composed of a driving component and a vacuum transduction component. In the driving component, an impeller is fixed at one end of a transmission shaft, the transmission shaft is positioned inside a left cavity through a bearing, and the transmission shaft and a driving wheel synchronously rotate. A plurality of left cavity permanent magnets are evenly arranged on the periphery of the driving wheel in an array mode, a left end cover is fixed on the left side of the left cavity, and a sealing ring is fixed on the left end cover through a gland. The vacuum transduction component comprises a first kind of vacuum transduction component and a second kind of vacuum transduction component. The underwater rotary type piezoelectric power generation device together has three structure styles. The underwater rotary type piezoelectric power generation device is used in water and can be effectively prevented from being damaged by extreme storm waves. Meanwhile, the output power of the underwater rotary type piezoelectric power generation device can be increased through the vacuum sealing cavity. The underwater rotary type piezoelectric power generation device is particularly suitable for collecting the kinetic energy generated by the flowing of the water particles in the environments such as the rivers and the oceans.

Description

technical field [0001] The invention belongs to the technical field of new energy, and is particularly suitable for converting kinetic energy generated by collecting river or ocean water particle flow 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, a small number of wave energy products have reached the practical ...
