Technical field
The present invention relates to cabin cover of wind power generator production field more particularly to engine room cover sealing devices.
Background technology
Wind power generator hubcap and engine room cover are the guiding devices covered on outside hub of wind power generator and generating set,
According to aerodynamic principle, generally streamlined shell, the air-flow of wind wheel can be led into, reduce resistance and protects unit wheel
All parts inside hub are not invaded and harassed by external environment, ensure unit normal operation, and the rotor due to generating set is being run
When, the port of rotor and engine room cover can generate gap, since the working environment of generating set is more severe, encounter dust storm, rain
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.
Invention content
In view of the deficiencies of the prior art, the present invention provides one kind effectively prevent misty rain and dust to enter axle sleeve, mainly
Prevent dust and rainwater from entering, moisture can be absorbed by drier, greatly prolong the service life of drier, machine simple in structure
