Abstract
The utility model discloses a safe braking mechanism applied to an incremental wind driven generator. The safe braking mechanism is characterized in that braking rods (7011, 7021) are connected by universal shafts (701, 702) on incremental plates (201, 202); and after the two braking rods penetrate through slide rails (601, 602) fixed on a shell (8), arc-shaped braking pieces (801, 802) at the ends of the rods are just positioned at the front end of a circular braking groove (3) in a circular braking disc (5) extending outside the shell (8) and rotating together with a crankshaft synchronously. The safe braking mechanism applied to the incremental wind driven generator is designed to push the braking rods to move backward when the incremental plates subjected to strong wind incline backward, so as to lean the arc-shaped braking pieces in the circular braking groove to form braking friction, so that the rotating speed of the generator is slowed down, the machine is prevented from being damaged caused by overhigh rotating speed of the generator due to typhoon, and the safe operation of the wind driven generator is guaranteed.
Description
Technical field
The utility model relates to the increment type wind-driven generator, especially a kind of safety-brake mechanism that is applied on the increment type wind-driven generator.
Background technique
In wind-power electricity generation, blast and storm can cause the fan blade hypervelocity rotation of wind-driven generator, and the mechanical energy that should exceed the speed limit sends generator to, cause the generator damage.Therefore, how slowing down generator speed under strong wind weather, also is a worldwide research topic.
In the face of this fatal stall phenomenon, the claimant is in the Chinese utility model patent application of " the weak wind on the wind-driven generator starts speed-raising and strong wind speed reducer " by name of the application's day submit, take with hinge-coupled increment plate, and the technological scheme of follow block spring is set between increment plate and casing, reach safe deceleration purpose.Its principle is, too fast when wind speed, when wind-force surpassed spring tension, spring was compressed, and the increment plate formation angle that recedes allows wind pass through fast, has removed the mechanicalness of increment plate, has reduced generator speed.The claimant thinks, the technological scheme that this guiding high wind passes through fast can only be removed the increment effect of increment plate, reaches the technical purpose that reduces generator speed, but lacks initiative, initiatively increase its braking and only have, could realize safe operation truly.
The model utility content
The technical problems to be solved in the utility model provides a kind of safety-brake mechanism that is applied on the increment type wind-driven generator, this mechanism can form braking automatically in the strong wind situation, reduce generator speed and ensure the generator safe operation, and simple in structure, cheap.
For realizing described purpose, technical solution adopted in the utility model is: the increment plate is movably connected on the electric generator casing by hinge, also be provided with a unit of braking device behind the increment backboard, this braking device unit and the rear arrestment mechanism that forms generator of another unit interaction that is arranged in the rotating shaft of generator afterbody.Specifically comprise electric generator casing, increment plate and arbor, especially also be to be connected with two brake rods by cardan shaft on the described increment plate, after brake rod passed the slide rail that is fixed on the casing, the arc braking plate of rod end just was positioned to extend to and is positioned at outside the casing and the front end of the annular stop groove of the circular brake disc of arbor synchronous rotary.
In the structure that technique scheme provides, the arbor of described generator extends to outside the electric generator casing, there is a circular brake disc end, this brake disc is to be formed by the high-abrasive material casting for the manufacture of the braking workpiece, cast annular groove in the casting hour indicator, this annular groove is in two unit of braking device described in the utility model, therefore, this groove is called the annular stop groove, when circular brake disc rotation, annular stop groove and arc braking plate hereinafter described interact, and have formed the arrestment mechanism of the utility model generator.Be fixed with a sealing slide rail at electric generator casing by rear position, after being installed in brake rod behind the increment backboard and passing the sealing slide rail, rod end is just referring at described annular stop groove front end, be provided with the arc braking plate of being made by high-abrasive material on the described brake rod rod end, normal condition arc lower braking plate does not contact with the annular stop groove.When wind speed excessive, when active force surpasses the tension force of the follow block spring between increment plate and the casing, the increment plate is just receded by under normal circumstances vertical flattened state and forms angle, at this moment, be connected to brake rod behind the increment backboard also along with the magnitude of inclination of angle moves backward, thereby the arc braking plate just is against in the annular stop groove, and the frictional force that these two brake units interact and form has been slowed down generator speed.This frictional force is along with the big or small self-assembling formation of wind-force, therefore, wind-force is larger, the power that the increment plate leans on backward is larger, and the frictional force that the arc braking plate on brake rod top is against in the annular stop groove is also just larger, otherwise, will be gradually little, evaded because hurricane stall causes the too fast machine breakdown that causes of generator speed, ensured the safe operation of wind-driven generator, realized safety technique purpose of the present utility model.
Described brake rod should be arranged on increment plate outer rim place, in order to utilize lever principle to provide a larger recoil for brake rod, is flexibly connected by cardan shaft between brake rod and the increment plate.
Compared with prior art, the arrestment mechanism that the utility model provides, in the time of can receding at the active force that the increment plate is subject to high wind, the brake rod that drive is arranged on behind the increment backboard moves backward, with the arc braking plate be against with the moving annular stop groove of generator arbor synchronous rotating in form drag friction, slow down generator speed, evaded because hurricane stall causes the too fast machine breakdown that causes of generator speed, ensured the safe operation of wind-driven generator.Because the utility model belongs to mechanical structure, manufacturing and maintenance cost are low, and stability is strong, and safety coefficient is high.
Below in conjunction with accompanying drawing the utility model is described further.

Embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, on the outer rim of two block incremental plates 201 and 202, connect two brake rods 7011 and 7021 by cardan shaft 701 with being connected respectively, after two brake rods 7011 and 7021 passed the fixed rack 601 and 602 that is arranged on the casing 8, the arc braking plate 801 on its top and 802 equal spot hovers were in the annular stop groove 3 of circular brake disc 5 inside.Circular brake disc 5 is and extends to electric generator casing generator arbor disjunctor outward that therefore, circular brake disc can be along with the rotation of generator arbor.Wind direction rudder 4 is fixed on the casing by connecting rod (omiting among the figure).When air quantity excessive, act on wind-force on the increment plate when being supported on follow block spring 1101 between increment plate and the casing and 1102 support tension force, the increment plate namely levels off the exhibition state and by the rotation that the connects hinge 9 formation angle that recedes, just discharged the incremental contribution under the flattened state, simultaneously, be connected to two brake rods 7011 and 7021 behind the two block incremental backboards also along with the magnitude of inclination of angle moves backward, thereby make two blocks of arc braking plates 801 and 802 just be against annular stop groove 3 interior formation frictions in the circular brake disc 5, frictional force has been slowed down generator speed.Because this frictional force is along with the big or small self-assembling formation of wind-force, therefore, wind-force is larger, the power that the increment plate leans on backward is larger, and the frictional force that the arc braking plate on brake rod top is against in the annular stop groove is also just larger, otherwise, will be gradually little, evaded because hurricane stall causes the too fast machine breakdown that causes of generator speed, ensured the safe operation of wind-driven generator, realized safety technique purpose of the present utility model.Along with weakening gradually of hurricane air quantity, weak to less than the setting tension force of tension spring 1101 and 1102 time, spring will back into flattened state again with the increment plate, and then arc braking plate 801 and 802 leaves annular stop groove 3, and generator recovers to run well.
