Stream material flies away under the action of the forces of the wind, causes boundless dust, serious pollution is caused to surrounding environment.
At present, it is main to solve above-mentioned dust pollution question using surface covering, spraying technique and wind-proof dust-suppression plate；It is right
For surface covering and spraying technique, not only need to invest repeatedly, and wind-proof dust-suppression is ineffective, and spraying technique is also
The problem of winter crust be present；And for existing wind shutter, although it has good wind-proof dust-suppression effect,
Because it does not have noise elimination noise reduction function, causing it to cannot be used for those has the wind-proof dust-suppression of noise elimination noise reduction demand environment；Separately
Outside, existing wind shutter is rigidly poor, and when large wind is acted on wind shutter, wind shutter can produce exciting, not only influence
The bonding strength of wind shutter, the generation of noise is also resulted in, causes noise pollution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of noise elimination noise reduction wind shutter, and it is with excellent wind-proof
While anti-dust effect, also there is very good rigidity and sqouynd absorption lowering noise performance, can be used for those has noise elimination noise reduction
The wind-proof dust-suppression of demand environment.
Technical scheme is used by the utility model solves its technical problem：A kind of noise elimination noise reduction wind shutter, it is described
Noise elimination noise reduction wind shutter is made up of the windproof backboard of the perforated plate positioned at weather and leeward side, and in described perforated plate and is prevented
Resonance sound-absorbing cavity configuration is formed between wind backboard.
Further, the section of the noise elimination noise reduction wind shutter is trapezoidal wave structure, has four cycles on wind shutter, and it is first
Tail is one flat section, and tundish contains two crests and a trough between described two crests.
Further, one piece of wave corrugation is additionally provided between perforated plate and windproof backboard in the inside of the wind shutter
Plate, the global shape of the wave corrugated sheet are consistent with the shape of wind shutter.
Further, the thickness of the perforated plate is 0.5-1.0mm, punching rate 28-30%, bore dia 10-20mm.
Further, the thickness of the wave corrugated sheet is 0.3-0.8mm, punching rate 25-28%, bore dia 8-
15mm。
Further, the thickness of the windproof backboard is 0.5-1.5mm, punching rate 23-25%, bore dia 3-5mm.
Further, described wave corrugated sheet by way of welding or being bonded respectively with perforated plate and windproof backboard
It is fixedly connected.
Further, described perforated plate, wave corrugated sheet and windproof backboard are homogeneous sheet material, are galvanized sheet, hot dip
One kind in aluminium zine plate, Al-Mg-Mn alloy plate or homogeneous sheet material made of macromolecule material.
The beneficial effects of the utility model are：Noise elimination noise reduction wind shutter of the present utility model has been internally formed resonance sound-absorbing chamber
Structure so that it has very good sqouynd absorption lowering noise performance；Meanwhile wind shutter uses the trapezoidal wave structure of dual waves, increase
The rigidity of wind shutter；In addition, one piece of wave corrugated sheet is additionally provided between perforated plate and windproof backboard, so as to further
Increase the rigidity of wind shutter and reduce wind-force and the exciting of wind shutter is acted on, to avoid producing noise and influence the company of wind shutter
Connect intensity.So noise elimination noise reduction wind shutter of the present utility model while with excellent wind-proof anti-dust effect, also has very
Good rigidity and sqouynd absorption lowering noise performance, can be used for those wind-proof dust-suppressions with noise elimination noise reduction demand environment.
Brief description of the drawings
Fig. 1 is the structural representation of noise elimination noise reduction wind shutter of the present utility model.
Fig. 2 is the partial enlarged drawing at a in Fig. 1.
Fig. 3 is the structural representation of wave corrugated sheet.
Fig. 4 is the structural representation of perforated plate and windproof backboard.
In figure mark for：1- perforated plates, the windproof backboards of 2-, 3- resonance sound-absorbing cavity configurations, 4- wave corrugated sheets.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples, but embodiment of the present utility model is unlimited
In this.
As Figure 1-Figure 4, noise elimination noise reduction wind shutter of the present utility model is by the perforated plate 1 and leeward side positioned at weather
Windproof backboard 2 form, and resonance sound-absorbing cavity configuration 3 is formed between described perforated plate 1 and windproof backboard 2；When sound wave from
After aperture on perforated plate 1 enters resonance sound-absorbing chamber, air vibration in cavity will be excited, when frequency of sound wave and resonance sound-absorbing chamber
When the resonant frequency of structure is equal, the air in resonant cavity will resonate, and switch to heat waste by friction, so as to play sound absorption
Effect；So there is the wind shutter of the application very good noise elimination noise reduction to act on.
Specifically, the section of the noise elimination noise reduction wind shutter is trapezoidal wave structure, there are four cycles, its head and the tail on wind shutter
It it is one flat section, tundish contains two crests and a trough between described two crests.The wind shutter of the application leads to
The trapezoidal wave structure using dual waves is crossed, the rigidity of wind shutter can be increased.
The exciting of wind shutter is acted in order to further increase the rigidity of wind shutter and reduce wind-force, to avoid generation from making an uproar
Sound and the bonding strength for influenceing wind shutter, one is provided between perforated plate 1 and windproof backboard 2 in the inside of noise elimination noise reduction wind shutter
Block wave corrugated sheet 4, the global shape of the wave corrugated sheet 4 is consistent with the shape of wind shutter, and wave corrugated sheet 4 passes through weldering
Connect and be fixedly connected respectively with perforated plate 1 and windproof backboard 2.
As a preferred embodiment, the thickness of the perforated plate 1 is 0.5-1.0mm, punching rate 28-30%, bore dia 10-
20mm。
As a preferred embodiment, the thickness of the wave corrugated sheet 4 is 0.3-0.8mm, punching rate 25-28%, bore dia is
8-15mm。
As a preferred embodiment, the thickness of the windproof backboard 2 is 0.5-1.5mm, punching rate 23-25%, bore dia 3-
5mm。
Found after applicant's test of many times, use thickness as 0.6mm, punching rate 28%, bore dia is wearing for 10mm
Orifice plate 1 and thickness are 0.5mm, punching rate 25%, and the wave corrugated sheet 4 and thickness that bore dia is 5mm are 1.0mm, punching rate
For 23%, bore dia is the wind shutter that 3mm windproof backboard 2 combines, when wind passes through three layers of perforated plate being serially connected successively
1st, after wave corrugated sheet 4 and windproof backboard 2, wind-force and wind speed can be greatly diminished, so wind shutter of the present utility model
With very good wind-proof dust-suppression effect.
As a preferred embodiment, described perforated plate 1, wave corrugated sheet 4 and windproof backboard 2 are homogeneous sheet material, it is plating
One kind in zine plate, hot dip aluminum zinc plate, Al-Mg-Mn alloy plate or homogeneous sheet material made of macromolecule material.So as to ensure this Shen
Noise elimination noise reduction wind shutter please has certain corrosion resistance.
In summary, noise elimination noise reduction wind shutter of the present utility model also has while with excellent wind-proof anti-dust effect
