High efficiency piezoelectricity power-generating device

Abstract

The invention discloses a high efficiency piezoelectricity power-generating device. The high efficiency piezoelectricity power-generating device is composed of a turbine rotor component, a spring sliding block component, a bending knocking rod component, and a piezoelectric vibrator component, wherein the turbine rotor component comprises turbine blades, a rotating shaft and a cam; the spring sliding block component comprises an installation cylinder, a pushing rod, an installation cylinder cover, a spring, a sliding block pushing rod and a supporting disc; the bending knocking rod component is composed of a round ring, a knocking rod, a rotating sliding block, a second pin and a supporting frame; and the piezoelectric vibrator component is composed of a piezoelectric material, a first electrode, a second electrode, a first guide wire and a second guide wire. According to the high efficiency piezoelectricity power-generating device, a mechanical cam connection rod mechanism and a sliding block mechanism are adopted, and the accuracy of part knocking each time can be guaranteed, so that more stable and efficient electric energy is generated; and the disadvantage that a device of providing knocking by centrifugal force is tightly adhered onto the piezoelectric vibrator because the centrifugal force is over high under the action of a high speed fluid and then is in failure.

Problems solved by technology

This solution has two disadvantages: one is that the piezoelectric bimorph collides with the cam and rubs against it every time it rotates, thus causing wear and tear, resulting in energy loss and reducing the service life

The main disadvantage of this solution is that when the vehicle passes by continuously and strong wind is generated, the sign will rotate at high speed, so that the steel ball will move close to the piezoelectric conversion element, and the piezoelectric element will not receive alternating pressure. can't generate electricity
