Abstract

The invention provides a composite rainwater power generation device based on a mini water bucket and a PVDF film piezoelectric technology, and belongs to the field of hydroelectric generation. The device solves the problems that an existing rainwater power generation device is high in cost and complex in installation and debugging. The device comprises a water level automatic control unit arranged on a water inlet of a rain drainage pipeline, a mini water buckle power generation unit arranged under the water level automatic control unit, and a PVDF piezoelectric module power generation unit arranged on a water outlet of the rain drainage pipeline. The water level automatic control unit comprises a floating ball, a V-type connecting rod, a partition board with a through hole, a valve and a magnet, wherein the V-type connecting rod is fixed to the inner side wall of the rain drainage pipeline, the lower portion of the V-type connecting rod is provided with the partition board with the through hole, and the valve is matched with the through hole in the partition board to control flowing and stopping of rainwater. The mini water bucket power generation unit comprises a mini water bucket hub, m mini water bucket vanes, a driving wheel, a driven wheel, a belt and a water bucket power generation circuit. The PVDF piezoelectric module power generation unit comprises a PVDF piezoelectric film and a PVDF power generation circuit.

Description

technical field [0001] The invention relates to a composite rainwater power generation device based on micro-water funnel and PVDF film piezoelectric technology, belonging to the field of hydropower generation. Background technique [0002] With the advancement of human civilization, energy and the environment have become major core issues facing the development of human society in the 21st century. The widely used fossil energy such as coal, oil and natural gas has caused serious impact and damage to the ecological environment, and its reserves are decreasing day by day, and the price is also rising. The resulting energy crises and wars are also increasing day by day. In order to realize the sustainable development of energy, on the one hand, my country must "open source", that is, to develop nuclear power, wind power and other new energy and renewable energy, and on the other hand, to "reduce expenditure", that is, to adjust the energy structure, and vigorously implement e...
