Multi-directional microminiature piezoelectric wind energy collector

Abstract

The invention relates to the technical field of wind power generation, in particular to a multi-directional microminiature piezoelectric wind energy collector which comprises a collecting body and a collecting body installed at the top of the collecting body, the collecting body comprises a base plate, a middle cylinder is arranged at the top of the base plate, a low rod is arranged in the middle of the bottom in the middle cylinder, and a piezoelectric module is fixed to the top of the low rod. A battery is arranged at the bottom in the middle cylinder, the piezoelectric module is electrically connected with the battery through a wire, a partition plate is arranged above the battery in the middle cylinder, a shaft groove is formed in the middle of the partition plate, the collecting body comprises a top cylinder located at the top of the middle cylinder, a through groove is formed in the top cylinder and is a groove of a partial inverted cone structure, and a top body is connected into the through groove through a support. The top body is of an inverted cone structure, the shaft groove is rotationally connected with an intermediate shaft, the intermediate shaft is symmetrically provided with a plurality of fan blades, and the bottom of the intermediate shaft is in threaded connection with a pressing rod. The device has the advantages that by arranging the piezoelectric module, collected wind energy is converted into electric energy to be stored.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a multi-directional miniature piezoelectric wind energy collector. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. Due to the huge amount of wind energy, wind power generation has begun to be developed. The wind power generator drives the generator to rotate through the wind blowing impeller. However, due to the large size of wind turbines, the deployment range is limited. In order to improve the utilization of wind energy, a small piezoelectric wind energy harvester is needed. Contents of the invention [0003] The purpose of the present invention is to provide a multi-directional micro-miniature piezoelectric wind energy harvester to solve the problems raised in the above-mentioned background technology.
