During the environment of mist, rainwater and dust can enter from gap in engine room cover, so as to cause the failure of fan operation, wind turbine be caused to be transported
Row stops.
China Patent Publication No. is 206017063 U of CN, a kind of engine room cover port sealing device is disclosed, including cabin
Cover body, axle sleeve is equipped at the port of the cabin cover body, and the interior surface of axle sleeve is equipped with groove, and installed successively in groove
There are dry housing and connecting plate, the surface of connecting plate is bonded with bristle, end face of the axle sleeve far from engine room cover ontology port
Equipped with annular cover plate, and annular cover plate is fixed by lock-screw and axle sleeve, positioned at the appearance of the axle sleeve of engine room cover body interior
Face is welded with annular mounting plate, and annular mounting plate is fixed by lock-screw and cabin cover body.By adding in annular installation
Plate due to annular mounting plate with axle sleeve by being welded and fixed, can increase the stability that axle sleeve is connect with engine room cover port, and
Gasket is equipped between annular mounting plate and the side wall of engine room cover, the sealing of annular mounting plate and engine room cover side wall can be increased
Property.It in axle sleeve by setting dry housing and connecting plate, by the setting drier in dry housing and in connecting plate
Bristle is set, achievees the purpose that remove dust and misty rain, but its technical solution can not prevent dust and misty rain to enter axis well
Set, causes misty rain and dust in axle sleeve to be largely collected in dry housing and bristle, needs to be replaced frequently dry housing and bristle,
It is time-consuming and laborious, it is further improved.
Utility model content
The utility model in view of the deficiencies of the prior art, provides one kind and misty rain and dust is effectively prevent to enter axle sleeve, main
If preventing dust and rainwater from entering, moisture can be absorbed by drier, greatly prolong the service life of drier, simple in structure
Engine room cover port multi-layer sealing structure.
To realize the utility model aim, following technical scheme is provided：A kind of engine room cover port multi-layer sealing structure, packet
Include engine room cover port, the axle sleeve being installed on engine room cover port, the rotor being inserted in axle sleeve, it is characterised in that axle sleeve exposes machine
The end set of hatch cover port has the first arc water blocking flange that a circle is dug upwards, and the stage casing of arc water blocking flange is provided with one
The second downward arc water blocking flange of circle, the end of the second arc water blocking flange are provided with elastic rubber slab, elastic rubber slab with
Rotor surface contact is provided with lip-type packing, lip-type packing setting in the axle sleeve on rear side of the second arc water blocking flange
In the groove opened up in axle sleeve correspondence, ring drying shell is provided on rear side of lip-type packing, drying is filled in ring drying shell
Agent, ring drying shell rear side are provided with resilient sleeve, and the resilient sleeve includes body, and body is provided with centre bore, covers in body sidewall
Corrugated elastomer is provided with, body inner wall is provided with graphite annulus.
Preferably, being welded with installing plate on axle sleeve, through-hole is offered on installing plate, bolt and engine room cover are set in through-hole
Housing at port is affixed.
Preferably, the first arc water blocking flange notch cooperation clamping opened up corresponding with end face of shaft bush.
Preferably, the end face that axle sleeve is located in engine room cover is provided with end cap.
The utility model advantageous effect：The utility model is effectively completely cut off by the way that the first and second arc water blocking is set to turn over water
Rainwater and dust enter axle sleeve, and by the way that resilient sleeve and graphite linings is set to increase sealing and lubricating action, substantially prolong
Axle sleeve inner annular dries the service life of shell, reduces maintenance times.
