The invention provides a kind of sealing device being used in Wind turbines yaw system, more particularly to a kind of anti-dust performance
Good sealing device, belongs to technical field of mechanical.
Background technology
Wind-driven generator is that wind energy is converted into mechanical work, the rotation of mechanical work rotor driven, the electricity of final output alternating current
Power equipment.Wind-driven generator typically has wind wheel, generator (including device), yaw system (empennage), pylon, speed-limiting safety mechanism
With the component such as energy storage device composition.Wherein yaw system is：By motor rotation cabin, so that rotor faces wind.Driftage
System is operated by electronic controller, and electronic controller can feel wind direction by wind vane.Generally, its direction is changed in wind
When, wind-driven generator once only can deflect the several years.Needing into during horizontal deflection, engine room cover can together rotate in company with whole device,
But the tower of wind-driven generator is fixed different again, therefore in the presence of rotating against between engine room cover meeting and tower, this will
Ask and there are certain gap between the two.However, in order to ensure that engine room inside does not enter dirt, manufacturing and installing engine room cover
When require that the gap between engine room cover and tower is the smaller the better.But, due to there is manufacture work difference and alignment error, machine
Sealing problem between hatch cover and tower cannot be solved preferably always.At the same time, due to being provided with driftage in engine room cover
Lubricant grease in gear, yaw gear can be between engine room cover and tower gap internal leakage come out.
The content of the invention
The invention provides a kind of dust-proof sealing device being used in Wind turbines yaw system, the apparatus structure is simple,
Favorable sealing property, can either prevent the lubricant grease in yaw gear from revealing, while the dirt in the external world can be prevented to enter again
Engine room inside；Most of all, the sealing device can adapt to axial dimension deviation different in engine room cover and radial dimension is inclined
Difference.
Realize technical scheme that above-mentioned purpose of the present invention used for：
A kind of dust-proof sealing device being used in Wind turbines yaw system, is installed between engine room cover and tower, tower
Top yaw system and yaw gear are installed, the engine room cover is covered in tower, yaw system and yaw gear,
The dust-proof sealing device at least includes the rotating ring and stationary ring of quality of rubber materials, and the bottom of engine room cover is provided with the platform extended internally
Rank, the rotating ring is fixedly installed on step, and the section of rotating ring is to be provided with one on U-shaped sealing channel-shaped, the inwall of U-shaped seal groove
Layer felt seal layer；Described stationary ring is made up of waist, neck and end, and three is fixed as one successively, wherein section of waist
Face is yi word pattern, and the inner side of waist is mutually fixed with tower, and whole stationary ring is fastened in tower by waist；Neck is U
Type elastic construction, end is located on the bottom on the outside of neck, and the end is inverted U clamp structure, and end is located at U-shaped seal groove
Inside；An oil storage tank is together form between described tower, waist and neck.
Axial felt isolating seal bar, the inverted U clamp structure folder of the stationary ring end are provided with described rotating ring
Hold in the both sides of felt isolating seal bar.
The neck of the stationary ring is additionally provided with cage, and the cage is arc structure, and cage is covered in U-shaped close
The top of sealing groove.
It is provided between described waist and tower for sealed sealing panel will to be carried out between waist and tower.
The bottom of U-shaped seal groove is circumferentially evenly arranged with fixing screws in rotating ring, and the fixing screws fix rotating ring
On step.
In the dust-proof sealing device that the present invention is provided, a storage is together form between outer wall, waist and the neck of tower
Oil groove, lubricant grease in the yaw gear of atop a tower directly can be dropped in oil storage tank in outflow, it is to avoid outer
Let out pollution environment.Rotating ring forms enclosing type structure with stationary ring, can prevent the dirt in the external world from entering in engine room cover.It is the most key
, installation deviation or production and processing work difference due to, when there are between engine room cover and tower radially (horizontal direction)
During deviation, the inverted U elastic construction of stationary ring neck can carry out radial elastic and stretch, and be always ensured that close between stationary ring and rotating ring
Seal effect；When deviation is excessive causes the end of stationary ring to be in contact with U-shaped seal groove, due to being set on the inwall of U-shaped seal groove
There is one layer of felt seal layer, when rotating ring and stationary ring are rotated against, felt seal layer can play the effect that profit is changed.Likewise,
When there are axial direction (vertical direction) deviation between engine room cover and tower, because the end of stationary ring is always positioned at U-shaped seal groove
It is interior, therefore can equally keep sealing effectiveness.
