Abstract
The invention discloses a brake protection device of an aerogenerator. The aerogenerator comprises a generator shaft and a shell and is characterized in that the brake device comprises a brake disc and a brake, wherein the brake disc is fixedly connected with the generator shaft, and the brake is fixedly connected with the generator shell corresponding to the brake disc. The invention has the advantages of simple structure, low production cost, less harm to the generator, simple operation and convenient maintenance, can ensure that the generator reliably runs or stops and is suitable for aerogenerators in all sizes.
Description
Technical field
The present invention relates to a kind of brake protection device of wind-driven generator, relate in particular to a kind of soft brake of wind-driven generator.
Background technique
The braking protection is an important protection content of wind-driven generator; because the unstability and the unexpected property of wind-force; must comprise the device that can make wind-driven generator under the strong wind situation, prevent driving in the component part of wind-driven generator; if the brake meeting causes damage to generator shaft rapidly, can reduce the working life of motor.Be head it off, what generally adopt in large-scale wind driven generator is that blade pitch device is realized slowly, braked.But because the restriction of build and cost performance, middle-size and small-size blower fan can't adopt blade pitch device to realize above-mentioned functions.
Summary of the invention
The present invention can make wind-driven generator realize flexible the deceleration when overspeed operation, and then make progressively stall of generator by brake block and brake disc in order to overcome the above problems the soft brake that a kind of wind-driven generator is provided.
Technological scheme of the present invention is: described wind-driven generator comprises generator shaft, housing, described braking device comprises brake disc, break, described brake disc is fixedly connected on the generator shaft, and the corresponding described brake disc of described break is fixedly connected on the generator housing.
Described break is connected with hydraulic system on the generator housing, and the face of the corresponding described brake disc of break is provided with brake block.Also be provided with spring on the described break.
The joint of brake disc and generator shaft is provided with jump ring.
Hydraulic system of the present invention drives break flexibly and contacts with brake disc, progressively increases surface friction drag, and final the realization stopped.The present invention is simple in structure, and cost of production is low, can guarantee the reliable stall of generator, and is little to the infringement of generator, simple to operate, easy to maintenance, is applicable to large, medium and small wind-driven generator.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is generator shaft among the figure, the 2nd, and brake disc, the 3rd, brake block, the 4th, break, the 5th, hydraulic system, the 6th, jump ring, the 7th, spring.
Embodiment
A kind of soft brake of wind-driven generator, described wind-driven generator comprises generator shaft 1, generator housing, described braking device comprises brake disc 2, break 4, described brake disc 2 is fixedly connected on the generator shaft 1, brake disc 2 is provided with jump ring 6 with the joint of generator shaft 1, described break 4 corresponding described brake discs 2 are fixedly connected on the generator housing, described break 4 is connected with hydraulic system 5 on the generator housing, the face of the corresponding described brake disc 2 of break is provided with brake block 3, also is provided with spring 7 on the break 4.When wind-driven generator need be braked; primer fluid pressing system 5; hydraulic system 5 provides pressure for break 4 and increases gradually; and with 7 compressions of the spring on the break 4; thereby the brake block 3 that break 4 is provided with contacts with brake disc 2; by the slow down rotating speed of generator of both frictions; because the characteristic that the pressure that hydraulic system 5 provides has controllability and gradually changes; can make wind-driven generator avoid anxious when brake stops; make its stall slowly; protected the main shaft of generator; when wind-driven generator does not need to brake; hydraulic system 5 oil returns, the spring 7 that break 4 is provided with can separate brake block 3 rapidly with brake disc 2, and wind-driven generator can normal operation.
Claims (4)
