For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of can the engine room cover air exhausting device of automatic open-close, comprise air bells exhauster, air exhaust channel, air draft be flexible coupling and venetian blind, engine room cover top is provided with exhaust port, and exhaust port is provided with upper overturning outside engine room cover, inside engine room cover, be provided with lower flange, air exhaust channel is seal-installed on upper overturning place, air draft is flexible coupling and is fixed on lower flange place, and is located between exhaust port and air bells exhauster, and venetian blind is installed on air exhaust channel.
Further, described air exhaust channel is bolted to nacelle top upper overturning place, attachment face gap sealant sealing.Upper overturning also has rainproof function.
Further, described air draft is flexible coupling and is fixed on lower flange place with pipe collar.
Further, described air exhaust channel outwardly one end is provided with in-flanges, and venetian blind is installed on in-flanges.
Further, described venetian blind comprises housing, blade and installation shaft, and housing bolt is installed on in-flanges, and installation shaft is welded in blade two ends, and blade is connected by installation shaft with housing.
Further, described blade is the aluminium flake of thickness 1mm.
Further, described blade is 0 ~ 60 ° around installation shaft rotation angle range.
Further, described sealer adopts SIKA221 sealer.
Further, the material that described air draft is flexible coupling is protective cloth, has sealing, waterproof, aging-resistant performance, and air exhaust channel is glass steel material, identical with the material of engine room cover.
The advantage that the utility model has and good effect are: this patent make use of the effect of air bells exhauster wind-force, by the sealing of air discharge structure, wind-force is all acted on shutter blade, to reach the effect of shutter blade automatic open-close, this structure is simple, reduce fabricating cost, improve air discharging and radiating efficiency.And overcome air discharge structure manually-operable or be in often open, normally closed problem, be beneficial to anti-bird and rainproof.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Fig. 1 ~ 7, a kind of can the engine room cover air exhausting device of automatic open-close, comprise air bells exhauster, air exhaust channel 2, air draft are flexible coupling 3 and venetian blind 4, engine room cover 1 top is provided with exhaust port, exhaust port is provided with upper overturning 5 outside engine room cover 1, inside engine room cover 1, be provided with lower flange 6, air exhaust channel 2 is bolted to upper overturning 5 place, engine room cover 1 top, attachment face gap SIKA221 sealant sealing.Air exhaust channel 2 is glass steel material.
Air draft is flexible coupling and 3 is fixed on lower flange 6 place with pipe collar, and is located between exhaust port and air bells exhauster.Air draft be flexible coupling 3 material be protective cloth.
Air exhaust channel 2 outwardly one end is provided with in-flanges, and venetian blind 4 is installed on in-flanges.Venetian blind 4 comprises housing 41, blade 43 and installation shaft 42, and housing 41 bolt is installed on in-flanges, and installation shaft 42 is welded in blade 43 two ends, and blade 43 is connected by installation shaft 42 with housing 41.Blade 43 is the aluminium flake of thickness 1mm.Blade 43 is 0 ~ 60 ° around installation shaft 42 rotation angle range.
During wind-driven generator high load running, air bells exhauster connects temperature transducer, gear-box because of operating temperature too high, air bells exhauster is started working, wind is flexible coupling by air draft and 3 is blown in air exhaust channel 2, and because of air exhaust channel 2 edge seal, wind-force blows to venetian blind 4, the blade 43 of venetian blind 4, under wind-force effect, is opened automatically.When air bells exhauster quits work, the blade 43 of venetian blind 4 automatically closes under Gravitative Loads.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
