Speed limiting device suitable for electromagnetic induction wind power generation

Abstract

The invention relates to the technical field of electromagnetic induction wind power generation, and discloses a speed limiting device suitable for electromagnetic induction wind power generation. Thespeed limiting device suitable for electromagnetic induction wind power generation comprises long-rod fan blades, the lower end surfaces of the long-rod fan blades are fixedly connected with the upper surface of a fixed mandrel, the lower part of the fixed mandrel is movably connected with a cam, and the left end surface of the cam is movably connected with a long rod. The wind power is increased, a magnet does magnetic induction line cutting motion, and induction currents are generated; when the speed exceeds a certain value, a speed limiting motor is started, pressing rods act downwards, sothat connecting rods connected with the pressing rods are compressed inwards, rubber plugs compress the columnar magnet inwards, and the magnetic induction line cutting motion speed of the columnar magnet is reduced; and when the speed is reduced to a certain rate, the speed limiting motor stops working, under the action of reset springs, the connecting rods restore to the original shape, the movement speed of the columnar magnet is increased, induction currents are increased, and the whole structure is circulated.

Description

technical field [0001] The invention relates to the technical field of electromagnetic induction wind power generation, in particular to a speed limiting device suitable for electromagnetic induction wind power generation. Background technique [0002] Wind energy is a clean and pollution-free renewable energy. With the rapid development of science and technology, people are using more and more clean energy. At present, wind energy is often used to generate electricity, and wind energy is used to make magnets cut magnetic lines in a closed circuit. Create potential energy in the circuit. [0003] During the implementation process, when the wind force is strong, the rotation speed of the fan blade will be accelerated very quickly, and the speed at which the magnet cuts the magnetic induction line will increase. At this time, the current passing through the circuit will increase. When the wind force is too fast, the magnetic induction line will be cut When the line rate incre...
