Background technology
Wind-driven generator can produce very big noise in the course of the work, and noise can not only accelerate building, mechanical structure
Aging, and the noise being discharged outside by air outlet can seriously endanger the auditory system of people, make one tired, deafness.Institute
Many sound-absorbing equipment can be placed for absorbing noise, harm reduction with inside and outside in wind power generating set.Wind-driven generator goes out
Due to its position reason at air port, absorptive filter device is not required nothing more than will reach 9-16db sound-absorbing effect in medium-high frequency, low frequency
Sound-absorbing effect can not be less than 3db, while to ensure the circulation of wind, it is ensured that in air quantity 3.5m3Resistance during/s is not more than 120pa,
Traditional micropore absorptive filter device will meet above-mentioned sound-absorbing amount, and its structural thickness can not be less than 1000mm, and add acoustical cotton
Windage can be very big while sound-absorbing amount is met for silencing filter, and the traditional scheme of existing wind-driven generator producer is to start
Suspension micropore louver filter one large-scale outside machine, to remove noise and ensure air quantity, but this scheme needs
External engine installs mounting bracket and protector additional, increases equipment cost.
Utility model content
The purpose of this utility model is to be arranged to make up the deficiencies in the prior art there is provided a kind of wind power generation unit equipment
Gas silencing filter, noise reduction and air quantity requirement, compact structure, the sound absorbing louver that may be mounted on the inside of air inlet can be met simultaneously
Window filter, it is possible to substantially reduce manufacture and the purchase cost of wind power generating set.
In order to reach the purpose of this utility model, technical scheme is as follows：
Outside a kind of wind power generation unit equipment exhaust noise silencing filter, it is characterised in that with aluminum alloy casing, aluminium alloy
Being provided with shell between some row's sound-absorbing combining structures, adjacent two rows sound-absorbing combining structure has space, and sound-absorbing is composite structure inclined
Set, sound-absorbing combining structure include outside aluminum fiber abatvoix and inside the aluminum fiber abatvoix from
A part installs the centrifugation acoustical cotton, another part and forms sky in heart acoustical cotton, the aluminum fiber abatvoix inner space
Chamber.
Preferably, the space is parallelogram sturcutre, has 30 ° -60 ° between sound-absorbing combining structure and horizontal plane
Angle.
Preferably, inside aluminum fiber abatvoix, the volume of the cavity is less than the volume that centrifugation acoustical cotton occupies.
Preferably, the cavity is located at aluminum fiber abatvoix internal edge, and cavity is close to the sky
Gap.
Preferably, the cavity is stating interval setting inside aluminum fiber abatvoix.
The utility model has the advantage that：
The noise produced in the wind power generation unit course of work passes through Novel noise-reduction shutter, first passes through aluminum fiber sound-absorbing
Plate can absorb part medium-high frequency noise, and remanent noise is centrifuged in cavity of the aluminum fiber abatvoix with centrifugation acoustical cotton
Acoustical cotton absorbs, by sound-absorbing twice, can be very good the lower noise that produces generator to desired decibel.It can expire simultaneously
Sufficient noise reduction and air quantity requirement, compact structure, the sound-deadening louver that may be mounted on the inside of air inlet, reduction wind power generating set
Manufacture and purchase cost.

Embodiment
The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1-Fig. 4, a kind of wind power generation unit equipment exhaust noise silencing filter, with aluminum alloy casing 1, aluminium
Alloy shell 1 is welded using 2.5mm aluminium alloy plate bending.Some row's sound-absorbing combining structures are provided with aluminum alloy casing 1,
There is space 5, space 5 passes through for air quantity between adjacent two rows sound-absorbing combining structure.Sound-absorbing is composite structure inclined to be set, and
There is 30 ° -60 ° of angle between sound-absorbing combining structure and horizontal plane, in the present embodiment, sound-absorbing combining structure and horizontal plane it
Between angle be 45 °.
The space 5 of formation is parallelogram sturcutre.At both ends, sound-absorbing combining structure is triangular structure, pars intermedia
The sound-absorbing combining structure divided is parallelogram sturcutre.
Sound-absorbing combining structure includes the aluminum fiber abatvoix 2 of outside and inside the aluminum fiber abatvoix 2
Centrifugation acoustical cotton 3, after the bending of aluminum fiber abatvoix 2, will centrifugation acoustical cotton 3 load inside aluminum fiber abatvoix 2.It is described
In the inner space of aluminum fiber abatvoix 2 part install it is described centrifugation acoustical cotton 3, another part not according to centrifugation acoustical cotton simultaneously
Form a cavity 4.
