Description

Wind-driven generator speed limit damped type braking system
Technical field
The utility model relates to a kind of wind-driven generator braking device, especially a kind of wind-driven generator speed limit damped type braking system.
Background technique
Wind energy has become the focus of human development as reproducible eco-friendly power source, and existing wind generating unit mainly comprises supporting frame, wind wheel, generator and to wind apparatus, mostly is the direct driving type wind driven generator that small-power runs up.One big critical component of wind-driven generator is exactly a rotor, and rotor rotation produces electric energy, in the continual rotation process of rotor, and also continual generation electric energy.When stopping rotor rotation, need realize by needs by braking system.The most frequently used braking model is mechanical braking and electric braking at present.Mechanical braking generally adopts the principle of gear engagement to brake, and this kind braking method has that period of braking is short to be waited a bit, but its equipment precision prescribed height, defective such as manufacture cost is high and exist wearing and tearing big, big to the collapsing force of equipment, and working life is short; Electric braking has that command range is far away, simple in structure, long service life etc. a bit, but its braking immediate current is very big, big to the collapsing force of motor.Under the strong wind situation, wind speed round is too high in addition, adopts existing mechanical brake structure and electric braking structure all to be difficult to can guarantee the safe in utilization of wind powered generator system again when realization is rotated wind wheel in a certain setting speed range.
The model utility content
The purpose of this utility model is to have proposed a kind of wind-driven generator speed limit damped type braking system, and it is simple in structure, the rotating speed of wind wheel can be limited in certain speed range, prolongs the life-span of wind-driven generator, guarantees the Security of wind-driven generator.
The utility model is to adopt following technological scheme to realize: a kind of wind-driven generator speed limit damped type braking system, comprise the braking hub, at least be provided with a brake shoe in the braking hub, brake shoe radially is provided with continuously along the braking hub, wherein, one end of brake shoe is provided with fulcrum, brake shoe can rotate along fulcrum, brake shoe is connected with the braking hub by fulcrum, connect by spring between the brake shoe that this end of brake shoe is adjacent simultaneously, the corresponding brake shoe the other end is a free end, be provided with magnetic material on the brake shoe and between the internal surface of brake shoe and braking hub, corresponding braking hub internal surface is provided with permeability magnetic material, has air gap between magnetic material and the permeability magnetic material.
The beneficial effects of the utility model are: this speed limit damped type braking system adopts machinery and electrical bond, wind wheel is limited in a certain setting speed range rotates, prevent that wind speed round is too high, guarantee that wind-driven generator still can safe operation under the strong wind situation, and obtain bigger power output; Can not produce bigger impact force in its braking process simultaneously, prolong the working life of wind-driven generator equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 2 is in working state not for the utility model;
Fig. 3 is the structural representation of the utility model when in running order.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 to Fig. 3 is a wind-driven generator speed limit damped type braking system described in the utility model.This system comprises braking hub 1, and braking hub 1 is fixedlyed connected with the wind wheel of wind-driven generator, brakes hub 1 and rotate with wind wheel when wind wheel rotates.Be provided with a plurality of brake shoes 2 in the braking hub 1, brake shoe 2 radially is provided with continuously along braking hub 1.One end of brake shoe 2 is provided with fulcrum, brake shoe 2 can rotate along fulcrum, and fulcrum is fixed on the braking hub 1, so brake shoe 2 is connected with braking hub 1 by fulcrum, connect by spring 5 between the brake shoe 2 that this end is adjacent simultaneously, spring 5 has certain pulling force.The other end of brake shoe 2 is a free end.Be provided with magnetic material 3 on the brake shoe 2 and between the internal surface of brake shoe 2 and braking hub 1, corresponding braking hub 1 internal surface is provided with permeability magnetic material 4.Spring 5 be except realizing the connection between the brake shoe 2, has certain air gap between magnetic material 3 in the time of can also making working state not on the brake shoe 2 and the permeability magnetic material 4.
In wind-driven generator when work,, along with the increase of wind speed round, the rotating speed of braking hub 1 increases gradually, increases gradually with centrifugal force on the brake shoe 2 that braking hub 1 is connected.When centrifugal force was enough big, brake shoe 2 overcame the pulling force of spring 5 and flies away from initial position.Rising along with wind speed round, the air gap that magnetic section bar material 3 on the brake shoe 2 and permeability magnetic material are 4 can be more and more littler, because the effect of cutting magnetic line can produce electromagnetic induction moment, when the torque of the electromagnetic torque that produces greater than wind wheel, wind speed round is reduced, thereby prevent that wind speed round is too high, the restriction wind wheel rotates in a certain setting speed range, guarantees wind-driven generator safe operation under the strong wind situation; Utilize this braking system can not produce bigger collapsing force simultaneously, prolonged the life-span of wind-driven generator equipment.
