Problems solved by technology

[0003] Most of the currently developed wind turbines are driven by windmills, and the piezoelectric vibrator is excited to generate electricity through indirect excitation components (picks, protruding teeth or steel balls, magnets); however, since there are many intermediate components involved, Not only is there serious friction loss, but it also produces noise and requires a large starting torque; especially when the size of the generator is smaller, the processing and assembly of the components are more complicated, the proportion of friction loss is greater, and the wear of accessories is also greater. serious
When magnets are used to form non-contact excitat

Abstract

The invention relates to a wind power piezoelectric electric generator. The wind power piezoelectric electric generator comprises a shell, a sealed space located in the shell, a driving shaft which isvertically arranged at the upper end of the shell and extends into the sealed space, blades arranged on the driving shaft, a driven shaft which is horizontally arranged in the sealed space and fixedthrough a bracket, a driving bevel gear and a driven bevel gear which connect the driving shaft with the driven shaft, fixed rods which are vertically fixed to the bottom of the sealed space, moving rods which are arranged on the fixed rods in a sleeving mode, a reciprocating mechanism arranged on the driven shaft for driving the moving rods to move vertically, an upper supporting ring arranged atthe upper ends of the moving rods, a lower supporting ring arranged at the lower ends of the fixed rods and a plurality of piezoelectric patches with two ends arranged on the upper supporting ring and the lower supporting ring correspondingly. According to the wind power piezoelectric electric generator, under the action of wind power, the blades can drive the reciprocating mechanism to drive themoving rods to move vertically, the piezoelectric patches are subjected to deformation, electric energy is excited, and the wind power piezoelectric electric generator has the advantages that the structure is simple, the size is small, the manufacturing is easy, the starting torque is low, the service life is long, and miniaturization is convenient.

Description
