Abstract

The invention discloses a wind energy rotary piezoelectric-electromagnetic composite power generation device, and relates to the field of piezoelectric-electromagnetic composite power generation and the field of new energy utilization. By means of the magnetic force between the wind energy and a magnet in a low-speed wind field, the power generation device can use a piezoelectric sheet to producea positive piezoelectric effect, and uses a coil to cut magnetic induction lines and simultaneously output a voltage, thereby solving the low power generation efficiency and low energy utilization rate under the low-speed wind field. The power generation device mainly consists of fan blades, a transmission shaft, a ceramic piezoelectric sheet, magnets, a coil, a spring and an elastic support layer. Under the effect of the wind, the fan blades periodically changes the magnetic force between a movable magnet and a fixed magnet, and stimulates the ceramic piezoelectric sheet and the coil to continuously act. The power supply to low-energy equipment with clean energy (wind energy) can avoid environmental pollution, a waste of resources and the like. The power generation device can improve thepower supply quality of low-energy electronic products in harsh environments (jungles, valleys, hillsides and the like).

Description

technical field [0001] The invention belongs to the field of piezoelectric-electromagnetic composite power generation, and in particular relates to a wind-driven rotary piezoelectric-electromagnetic composite power generation device. Background technique [0002] With the rapid development of the electromechanical industry, wireless sensor technologies such as micro-electromechanical systems (MEMS) and low-power embedded technologies are increasingly becoming integrated, intelligent, and miniaturized. Therefore, there is a higher demand for its energy supply industry, but because the traditional energy supply industry has been stagnant, the disadvantages of battery power supply (small capacity, short life, easy to be restricted by the environment, difficult to recycle, easy to cause heavy metal pollution) It is also gradually emerging, which seriously limits the development of wireless sensing technology. Using clean energy to power low-energy electronic devices has become ...
