Electric energy collecting device and use method thereof

Abstract

The invention discloses an electric energy collecting device and a use method thereof. The device comprises a piezoelectric unit, the piezoelectric unit is fixed in a fixed seat, the fixed seat comprises a fixed plate, a base and a mounting seat in an integrated structure; a pressing block is movably arranged in the mounting seat, the bottom of a counterweight block is fixedly connected with a push rod; the push rod penetrates the piezoelectric unit and is movably arranged in the base; the piezoelectric unit is electrically connected with a rectifier circuit, a charging management module and accumulators in order through a conductor. The fixed seat is rolled through a wheel so as to push the pressing plate to provide pressure for the piezoelectric unit, and then the piezoelectric unit generates power, the counterweight block can repeatedly vibrated up and down under the effect of a first spring and a second spring, thereby improving the power generation efficiency of the piezoelectricunit; the current integrated by the rectifier circuit can be stored in the accumulator; the sufficient electric quantity can be stored by arranging multiple accumulators, the accumulators are in mutual backup, and the practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of electric energy collection devices, and in particular relates to an electric energy collection device and a method for using the same. Background technique [0002] With the shortage of fossil energy and the pollution of the environment, more and more researchers have begun to study new energy sources in order to achieve efficient use of energy and clean energy. In the prior art, there is a device for generating electricity by using the vibration of the track, but the structure of the electricity generating device in the prior art is relatively complicated. [0003] For this reason, application number is the patent of CN201721120149.9, and it discloses a kind of rail electric energy collection device. The electric energy collection device includes a piezoelectric collection bag and an electric energy storage device, the piezoelectric collection bag is arranged on a track, the piezoelectric collection bag...

Problems solved by technology

[0004] However, the above scheme has the following defects in use: since the device is directly crushed by the wheels, the loss to the device is relatively large. In addition, the wheel rolling device can only be used to generate electricity when the wheels pass by, and after the wheels leave, the piezoelectric If the collection unit loses its force, it will not be able to continue to generate electricity, and the power generation efficiency is low
