Vertical-vibration horizontal-swinging type power generation device of low frequency large amplitude piezoelectric cantilever beam

Abstract

The invention relates to a vertical-vibration horizontal-swinging type power generation device of a low frequency large amplitude piezoelectric cantilever beam, which belongs to the technical field of new energy and power generation. A casing is installed on a base through screws, and a first group of magnets and a second group of magnets are evenly bonded to the inner wall of the casing. A first spring, an inertia block and a second spring are sequentially sleeved on a pin roll from top to bottom. One end of a piezoelectric vibrator is connected with a magnet in bonding mode, and the other end of the piezoelectric vibrator is inserted in a direct groove of the inertia block. The first group of magnets and the second group of magnets and the magnet installed on the piezoelectric vibrator are installed with the same poles close to each other. The power generation device has the advantages of utilizing the environment to vibrate vertically to enable the piezoelectric vibrator of the cantilever beam to swing horizontally in the horizontal level, being capable of achieving low frequency large amplitude vibration energy recycle and being high in reliability.
