The composition such as frame, storage battery charge controller, inverter, unloader, net-connected controller, battery group.Cabin cover of wind power generator is made
Shell is protected for wind power generating set, reliability determines the stability and service life of running of wind generating set.Wind-power electricity generation
All component covers in cabin wherein, are isolated from the outside by engine room cover.Important component of the engine room cover as wind power generating set,
It is the safeguard structure of wind power generating set, wind power generating set is enable to work normally in severe weather environment, protection is internal
Equipment and personnel not by the wind, the infringement of the external environmental factors such as rain, snow, salt fog, ultraviolet radioactive.Under this environmental condition,
Guarantee that Wind turbines work normally 20 years, it is desirable to which engine room cover has high quality, high reliability.
Need strictly to be sealed at gap between engine room cover and generator support, so as not to rainwater enter engine room cover it is interior or
Person, which enters in generator, brings serious influence.However, with the transformation of wind direction, engine room cover is phase due to during the work time
There is rotation for tower, since the volume of engine room cover is larger, engine room cover is relative to generator support during rotation
Gap will do it variation, therefore general sealed waterproof device can not be thoroughly close in the realization of the process of this dynamic change
Envelope.
Summary of the invention
