9% has invested China in global wind-powered electricity generation fund, and total value is up to 16.2 hundred million Euros (about 162.7 hundred million yuans).2007, Chinese feature
The electric installed capacity ranking world the 5th.
Wind power generating set includes wind wheel, generator；Containing the composition such as blade, wheel hub, reinforcing member in wind wheel；It has blade by
The functions such as Wind-driven rotating power generation, the rotation of generator head.Wind-power electricity generation power supply is by wind power generating set, the tower of support generating set
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.
Since during the work time, with the transformation of wind direction, engine room cover is that have rotation relative to tower, it is therefore desirable to
Sealing device is set between engine room cover floor and tower, first is that grease is revealed in the engine room cover of top in order to prevent, second is that avoiding outer
Rainwater, the dirt on boundary etc., which enter, damages equipment in engine room cover.However due to the enlargement of equipment, engine room cover during rotation
There is also the beats having axially and radially between tower, therefore general labyrinth gland can not be applicable in.In the prior art
General to use the stationary ring hairbrush on engine room cover floor, the inner face of hairbrush is contacted with tower surface, however such sealing means
Sealing effect is bad.
Summary of the invention
The utility model solves deficiency in the prior art, provides a kind of oil-collecting dust guard, the device leakproofness
Can be good, the effect of dust-proof oil-collecting can be played, the beat workplace suitable for wind power generating set.
Realize technical solution used by the utility model above-mentioned purpose are as follows:
A kind of oil-collecting dust guard in wind power generating set, is installed between tower and engine room cover bottom plate, to two
Gap between person is sealed, and the oil-collecting dust guard is made of stationary ring and rotating ring, and stationary ring is by waste oil slot, stationary ring connection ring
And O-ring composition, waste oil slot is whole annular in shape and covers on the outer surface of tower, and the section of waste oil slot is in U-shape, and waste oil slot passes through
Cricoid hose clamp, which is tied tight, to be fixed on the surface of tower, and O-ring is located at the outer side-lower of waste oil slot, and stationary ring connection ring is by O-ring
Top and waste oil slot bottom between be flexibly connected；The rotating ring is by fixed ring, rotating ring connection ring, outer baffle ring and interior gear
Ring composition, wherein fixed ring is flattened on engine room cover bottom plate, and is mutually fixed by pressing plate with engine room cover bottom plate；Rotating ring connection ring,
The section that outer baffle ring and inner baffle ring three are collectively formed is in Y-shaped, and the bottom of rotating ring connection ring connect with fixed ring, outer baffle ring and
The section of inner baffle ring is arc, and the two collectively constitutes that a section is rounded and open-topped cyclic structure；The outer gear
Ring and inner baffle ring sandwich O-ring inside it, and are provided with gap between the two.
The bottom of the O-ring is provided with opening.
The thickness of the outer baffle ring and inner baffle ring is gradually reduced from the bottom to top.
Compared with prior art, the utility model has the advantage that in 1, the utility model since waste oil slot to be bonded
It is fixed in the circumference of tower, and the section of waste oil slot is in U-shape, therefore by top yaw bearing and tooth can be yawed by waste oil slot
The Grease Collection of the leakages such as wheel, prevents gap of the grease between blower fan tower barrel and engine room cover from leaking.2, the outer baffle ring in rotating ring
And inner baffle ring sandwiches O-ring inside it, and is provided with gap between the two.Above-mentioned outer baffle ring, inner baffle ring and O-ring together with
Rotating ring connection ring and stationary ring connection ring are formed together sealing partition, the gap between blower fan tower barrel and engine room cover bottom plate are carried out close
Envelope prevents the pollutants such as extraneous sand and dust from immersing cabin along the gap between blower fan tower barrel and engine room cover.3, since stationary ring connects
Ring is flexible structure, outer baffle ring and inner baffle ring and O-ring is flexible structure, therefore when engine room cover is sent out with change of the wind
Raw rotation makes, even if rotating ring is relative to stationary ring, there are beats axially and radially, can also guarantee the leakproofness of device.
