Wind driven generator with self-adjusting rotating speed

Abstract

The invention relates to the strategic emerging technical field, and discloses a wind driven generator with a self-adjusting rotating speed. The wind driven generator comprises a wind wheel shaft, one end of the wind wheel shaft penetrates through a cabin, one end of the wind wheel shaft is fixedly sleeved with a rotor, and the end, close to the cabin, of the rotor is fixedly connected with a second collecting ring. The wind wheel shaft is movably sleeved with a brake assembly, one end of the brake assembly is fixedly connected with a second electric brush penetrating through one end of the cabin, the second electric brush is clamped in the second collecting ring, and the center of the front end of the cabin is fixedly connected with a first collecting ring. According to the wind driven generator with the self-adjusting rotating speed, through designed main blades, designed auxiliary blades and designed movable electromagnets, when external wind power changes greatly, under the action of centrifugal force, the electromagnets displace, the magnitude of current received by the brake assembly is changed, the brake force of the brake assembly is reduced or increased, and therefore the speed reduction effect of the wind wheel shaft is reduced or increased, and the rotating speed of a wind wheel is kept within a safe range.

Description

technical field [0001] The invention relates to the technical field of strategic emerging industries, in particular to a wind power generator with self-adjusting speed. Background technique [0002] Wind power generator is a kind of electrical equipment that converts wind energy into mechanical energy to rotate the rotor of the generator, and finally outputs alternating current. It mainly drives the wind wheel to rotate through wind force, and the wind wheel converts it into mechanical energy to drive the wind wheel shaft to rotate, and then the wind wheel shaft Drive the generator to rotate to obtain electric energy; [0003] Because the magnitude of the wind force cannot be controlled by humans, generally a breeze speed of three meters per second can make the wind wheel rotate to generate electricity. At this time, the wind wheel rotates slowly, and the wind wheel shaft needs to be accelerated by the speed-increasing mechanism to increase its rotation speed. The power gen...

Problems solved by technology

[0004] In view of the deficiencies in the use of existing wind power generators proposed in the background technology, the present invention provides a wind power generator with self-adjusting speed, which has automatic acceleration at low speeds, self-regulation of the speed according to the speed of the blades, The advantage of reducing the centrifugal force when the blade speed is too large solves the problems of low wind power generation efficiency, high wind speed damage to the power tower, manual speed regulation out of control and untimely problems raised in the above background technology
