Description
Technical field
The utility model is related to the sound-deadening and noise-reducing equipment technical fields of wind turbine, especially relate to a kind of wind turbine silencing means.
Background technology
There are many wind turbine types, is used in different industries, but can all generate prodigious noise, influences the physical and mental health of people.Separately
Outside, the noise of wind turbine some be because vibrations generate.Existing centrifugal blower denoising device effect is undesirable.
Invention content
In order to solve problems in the prior art, the utility model provides a kind of simple in structure, good wind of noise-reducing effect
Machine silencing means.
Technical solution described in the utility model is as follows：
A kind of wind turbine silencing means, including babinet, the babinet is interior to be equipped with centrifugal blower, and the centrifugal blower is logical
Floor installation is crossed on damper, air port, the centrifugal blower are opened up on the babinet on the air outlet top of the centrifugal blower
Lateral surface be equipped with sound insulation enclosing, the sound insulation enclosing is unlimited in the leading flank of centrifugal blower, the sound insulation enclosing
Madial wall be equipped with damping layer, the sound insulation enclosing is equipped with sound-absorption hole, and the inner wall of the babinet is equipped with several
Groove, the groove is interior to be equipped with muffler, in the cavity between the inner wall and outer wall of the babinet successively close to outer wall side
Equipped with the first acoustical cotton and the second acoustical cotton.
The unit weight of first acoustical cotton and the second acoustical cotton is different.
The thickness of the damping layer is 0.8-1.5cm.
Uniformly distributed sound-absorption hole on the inner wall of the babinet.
The advantageous effect that technical solution provided by the utility model is brought is：
By the way that sound insulation enclosing is arranged in the outside of centrifugal blower, the noise that can be generated to wind turbine tentatively reduces, fan bottom
The damper in portion can alleviate the vibrations of wind turbine, reduce noise, improve the service life of wind turbine, the muffler pair on cabinet wall
The secondary noise reduction of wind turbine, acoustical cotton drops to the noise of wind turbine most wind turbine noise reduction three times in cavity between cabinet wall and outer wall
It is low, improve the working environment in workshop.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, a kind of wind turbine silencing means, including babinet 1, the babinet 1 is interior to be equipped with centrifugal blower 2, institute
On damper 3, wind is opened up on the babinet 1 on the air outlet top of the centrifugal blower 2 by floor installation for the centrifugal blower 2 stated
The lateral surface of mouth 4, the centrifugal blower 2 is equipped with sound insulation enclosing 5, and the sound insulation enclosing 5 is in the leading flank of centrifugal blower 2
Open, the madial wall of the sound insulation enclosing 5 is equipped with damping layer 6, and the sound insulation enclosing 5 is equipped with sound-absorption hole, described
The inner wall of babinet 1 be equipped with several grooves 7, be equipped with muffler 8 in the groove 7, the inner wall of the babinet 1 with it is outer
It is equipped with the first acoustical cotton 9 and the second acoustical cotton 10 successively close to outer wall side in cavity between wall.
First acoustical cotton 9 is different with the unit weight of the second acoustical cotton 10.
The thickness of the damping layer 6 is 0.8-1.5cm.
Uniformly distributed sound-absorption hole on the inner wall of the babinet 1.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
