Description
The utility model wind-power electricity generation protector relates to is a kind of safety protection device that can protect wind-driven generator not to be damaged automatically when meeting air blast.
Present wind-driven generator can't use in the area of wind resource deficiency, also can't under the situation that air blast (violent typhoon) often arranged, use, for the existing power-driven generator leaf sheet of safety number designs fewly, and blade is narrow, so just can't be generalized to some wind-resources shortages or the unstable area of wind-force (violent typhoon often attacks the area) and use.
The purpose of this utility model is to have deficiency at present wind-driven generator; a kind of wind-power electricity generation protector is provided; protective gear with resilient push, elastic draw bar, balance ring formation; simple in structure, in light weight, when meeting air blast (violent typhoon); can change the fan blade angle of inclination; reduce wind resistance, stable generator rotating speed, reach the protection fan blade, the purpose that wind-driven generator is not damaged.
The wind-power electricity generation protector takes following scheme to realize: wind-power electricity generation protector structure is made of resilient push, elastic draw bar, balance ring, connecting pin, fan blade axle cap, fan blade blowout patche, adjustable leaf blade.Fan blade blowout patche front end is equipped with the fan blade axle cap, and device has some adjustable leaf blades on the fan blade blowout patche.Resilient push has push-rod piston, push-rod piston is assemblied in the axle sleeve, thrust spring is housed in the axle sleeve, thrust spring one end leans on push-rod piston, the other end withstands on the axle sleeve bottom, all there is connecting head at the resilient push two ends, and the push-rod piston end connecting head and the adjustable leaf blade of resilient push are hinged, and sleeve end connecting head and balance ring are hinged.Elastic draw bar has the pull bar piston, the pull bar piston is contained in the drag link sleeve, spring housing is contained on the pull bar piston, spring one end is positioned at the pull bar pistons end, the other end is positioned at the drag link sleeve inner end, the elastic draw bar two ends are equipped with connecting head, and the drag link sleeve one end connecting head of elastic draw bar and fan blade blowout patche are hinged, and the pull bar piston end connecting head and the balance ring of elastic draw bar are hinged.Balance ring is sleeved on the generator slide outside and cooperates.
The wind-power electricity generation protector is assemblied on the wind-driven generator; can make wind-driven generator adorn fan blade more; and fan blade can be widened; so just can make wind-driven generator lack the area at wind resource uses; this device is primarily aimed under the situation of air blast (violent typhoon) and fan blade wind driven generator is not destroyed designed; adjustable leaf blade can recede automatically when meeting air blast (violent typhoon); do not reduce the windage value with this; when wind-force is big more; in resilient push; elastic draw bar; the fan blade angle that recedes is big more under the balance ring effect; but obtain stable support and be controlled to several angle; the wind-driven generator rotating speed is kept relative stability; the suffered wind-force effect of fan blade is reduced relatively; make generator shaft accept kinetic force and keep normal value; after the abatement of wind; because the protective gear effect makes adjustable fan blade be returned to the original state normal rotation; this protective gear is reasonable in design simple in structure; it is low to be convenient to make cost; can play certain rotating speed control action; do not cause any wearing and tearing with generator, can reduce the cost of electricity-generating of certain areas.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is wind-power electricity generation protector structure and user mode schematic representation.
Fig. 2 is a wind-power electricity generation protector resilient push structural representation.
