Embodiment
As shown in Fig. 2 and Fig. 4, the shape of the air guide sleeve of this wind power generating set is roughly the housing of semielliptical shape, and the windward side 2 that there is open side 1 and close.Because windward side 1 is streamlined structure, carry so the wind that air guide sleeve self bears effectively can be reduced.Because air guide sleeve is wrapped in the wheel hub (not shown) supporting fan blade (not shown), thus form closed inner space in wheel hub.
Circumferencial direction along air guide sleeve is formed uniformly multiple vane holes 8 of blower fan, extend into the inside of air guide sleeve through the vane hole 8 of air guide sleeve by the end of the fan blade of hub support, and be connected with the pitch motor in axial fan hub, thus fan blade is rotated under wind-force effect, with by wind energy transformation for electric energy.Preferably, the quantity of vane hole 8 is three.
Air guide sleeve is formed Escape hatch 3, Escape hatch 3 is provided with euphotic cover plate 4, between the outer ledge and the inwall of Escape hatch of euphotic cover plate, be also provided with sealing component.Euphotic cover plate can adopt various lucalox to obtain, as adopted transparent toughened glass or transparent plastic.One end of euphotic cover plate 4 adopts articulated manner to be connected with the edge of Escape hatch 3, and the other end is then connected with the edge of Escape hatch 3 by locking framework or latch.
In addition, when euphotic cover plate adopts mosaic technology to be embedded in Escape hatch, the material preferably clear toughened glass of euphotic cover plate.Thus, translucent effect is better.
In addition, when euphotic cover plate adopts screw to be installed on Escape hatch, the material preferably clear plastics of euphotic cover plate.Thus, transparent plastic is not easily broken when installing or removing bolt.
Euphotic cover plate makes extraneous light can enter into air guide sleeve inside through euphotic cover plate, effectively serves the effect of illumination.Thus, be convenient to the equipment of staff to air guide sleeve inside and overhaul, it also avoid staff in maintenance process because peripheral situation cannot be seen clearly injured potential safety hazard.
In the present embodiment, the quantity of Escape hatch is three, and three Escape hatches can make the light of air guide sleeve inside more sufficient, and illuminating effect is better, and more convenient staff is to the maintenance of parts all in air guide sleeve.Three Escape hatches are uniformly distributed along the circumferencial direction of air guide sleeve, and wherein, each Escape hatch is arranged between two adjacent vane holes.
Euphotic cover plate 4 offers multiple air hole 5, and the edge of this air hole 5 extends to its top with the rain cover 6 formed with a side opening.Hot gas in air guide sleeve can be derived by air hole, or the gas of outside is blown in drainage hood, to realize the circulation of gas in air guide sleeve.
In the present embodiment, the edge of air hole 5 is that curved shape extends to its top circumference direction, with formed with outer gibbosity and side with the arc-shaped rain cover 6 of opening, rainwater can be avoided to enter the inside of air guide sleeve by rain cover, damage is caused to the parts of air guide sleeve inside.
Multiple longitudinal convex tendon 7 is evenly equipped with at the circumferencial direction of the inner wall surface of air guide sleeve.Wherein, the cross section of longitudinal convex tendon 7 can be rectangle, fan-shaped or triangle.In the present embodiment, the cross section of longitudinal convex tendon 7 can be rectangle.Longitudinal convex tendon can reduce the thickness of air guide sleeve, improves the working life of air guide sleeve, can also improve the join strength between air guide sleeve and corollary equipment, improves the operating Safety performance of wind-driven generator.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
