Description
Technical field
It is to be related to a kind of new offshore wind farm cabin specifically the present invention relates to wind-driven generator correlative technology field
Tower sealing structure and wind turbine.
Background technology
Engine room cover is used to protect cabin inner part from being directly exposed to external complex, adverse circumstances, is playing guarantee unit just
Often operation, extension unit service life, reduce fan operation resistance and be to install and operating personnel provide necessary operating space
Deng effect.
Offshore wind farm engine room cover is subjected to wind-force, sleet, ultraviolet and salt fog etc. for a long time due to its complicated use environment
Corrode, therefore have comparing requirement high to its sealing etc..But tower needs guiding through engine room cover and is directly connected with main frame, due to inclined
Therebetween need the presence of gap the need for boat, while in the case that design gaps are too small, machining accuracy to each part of unit,
Build-up tolerance needs proposition more strict requirements, is unfavorable for the lifting of unit overall price/performance ratio.
Existing sealing means are essentially one layer of sealing hairbrush of simple setting between and are used with doing sealing, and it can reach
It is applied to land blower fan to certain sealing effectiveness, it is impossible to meet the seal request of offshore wind farm unit well.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of new offshore wind farm cabin tower is close
Seal structure.The present invention is improved by existing sealing structure, the use requirement for alloing it to meet maritime environment.
In order to reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of new offshore wind farm cabin tower sealing structure, including：Engine room cover and outside the tower of engine room cover side
Wall；
The engine room cover is fixedly connected with hairbrush support, has multiple hairbrush on hairbrush support；
Sealing shield ring is provided with the tower drum outer wall；
The hairbrush forms labyrinth seal with Sealing shield ring.
Preferably, the hairbrush support is T-type structure.
Preferably, the hairbrush support is multiple small rack splicing connections.
Preferably, the hairbrush includes the first hairbrush being fixedly connected with hairbrush support downside and consolidates with hairbrush frame bottom
Fixed two the second hairbrush for connecing；
First hairbrush and the second hairbrush are pressed against on Sealing shield ring.
Preferably, the Sealing shield ring is bending structure；
There is the 3rd hairbrush on Sealing shield ring；
Second hairbrush, the 3rd hairbrush, the first closed chamber is formed between hairbrush support and Sealing shield ring.
Preferably, the second closed chamber is formed between the first hairbrush, the second hairbrush, hairbrush support and Sealing shield ring.
While said structure scheme is provided, present invention also offers a kind of wind turbine, the wind turbine has above-mentioned
Sealing structure.
The beneficial effects of the invention are as follows：
Sealing hairbrush is set between Sealing shield ring and hairbrush support simultaneously, the gap between cabin and tower is formed labyrinth type
Closed chamber, increases cabin sealing effectiveness, meets the requirement of offshore wind farm use environment.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the scheme of installation of sealing structure in the present invention；
In figure：
1 is engine room cover, and 2 is Sealing shield ring for tower drum outer wall 2,3, and 4 is hairbrush support, and 5-1 is the first hairbrush, and 5-2 is the
Two hairbrush, 5-3 is the 3rd hairbrush, and 5-4 is the first closed chamber, and 5-5 is the second closed chamber.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment 1：A kind of new offshore wind farm cabin tower sealing structure, its structure as shown in figure 1, including：Engine room cover 1
And positioned at the tower drum outer wall 2 of the side of engine room cover 1；The engine room cover 1 is fixedly connected with hairbrush support 4, has on hairbrush support 4 many
Individual hairbrush；Sealing shield ring 3 is provided with the tower drum outer wall 2；The hairbrush forms labyrinth seal with Sealing shield ring 3.
The hairbrush support 4 is T-type structure, and hairbrush support 4 is multiple small rack splicing connections.Under hairbrush support 4
Portion side is fixedly connected with the first hairbrush 5-1, and bottom is fixedly connected with the second hairbrush 5-2, the first hairbrush 5-1 and second mao
Brush 5-2 is pressed against on Sealing shield ring 3.
The Sealing shield ring 3 is bending structure；There is the 3rd hairbrush 5-3 on Sealing shield ring 3, and the 3rd hairbrush 5-3 is by hair
Brush support 4 is pushed so that the second hairbrush 5-2, the 3rd hairbrush 5-3, the sealing of formation first between hairbrush support 4 and Sealing shield ring 3
Room 5-4；First hairbrush 5-1, the second hairbrush 5-2, the second closed chamber 5-5 is formed between hairbrush support 4 and Sealing shield ring 3.
The seal process of above-mentioned sealing structure is：
The Sealing shield ring 3 of bending form as shown in Figure 1 is made, makes Sealing shield ring 3 that there are two or more steps, while
Its top is provided with the 3rd horizontal hairbrush 5-3；
Secondly, Sealing shield ring 3 is sectionally smooth join, by strong magnets or other to be detachably connected form (such as bolt) solid
Due to the relevant position of tower drum outer wall 2；
Again, " T-shaped " hairbrush support 4 as shown in Figure 1 is made, the hairbrush support 4 has lateral part and vertical part,
