Method for collecting piezoelectric energy by wind energy and device thereof

Abstract

The invention discloses a method for collecting piezoelectric energy by wind energy and a device thereof, wherein, a rotating carrier is driven by wind energy so that a permanent magnet on the rotating carrier produces a repulsive force on a fixed magnet on a cantilever beam to drive the cantilever beam to vibrate; and after a piezoelectric material on the cantilever beam is deformed, the energy is generated and then collected. In the invention, the wind energy is transformed into mechanical vibration energy to generate electricity and then supply power to a sensor or other low-power consumption systems, thus being free from restriction of a vibration source to realize convenient use. The device of the invention further has the characteristics of simple implementation structure. The invention can be used in preliminary power supplies of a plurality of wireless communication equipment and a charging apparatus for a small-sized rechargeable battery.

Description

technical field [0001] The invention relates to a method and device for utilizing wind energy, in particular to a method and device for collecting wind energy in a piezoelectric manner.

Problems solved by technology

Although this energy harvesting method has high efficiency, it must have a vibration source of mechanical vibration to play its role.

In some special cases, it is difficult to find an effective vibration source to supply wireless communication equipment, such as remote places such as deserted islands and uninhabited mountains, which brings inconvenience to sending out distress signals and timely contact with the outside world.
