Abstract
The utility model discloses a damping ventilation louver window. The louver window comprises a support frame, wherein multiple damping louver blades are arranged on the support frame parallelly at equal intervals, each louver blade is formed by a horizontal louver and an oblique louver, the horizontal louvers are arranged on the inner side of the louver window, the oblique louvers are arranged at the outer side of the louver window, and a punched rain shielding plate vertical to the ground is arranged between the horizontal louvers and the oblique louvers; a horizontal sound insulation layer is arranged between a horizontal upper plate and a horizontal lower plate of each horizontal louver, an oblique sound insulation layer is arranged between an oblique upper plate and an oblique lower plate of each oblique louver, and both the horizontal sound insulation layers and the oblique sound insulation layers are filled with sound absorption cotton. According to the damping ventilation louver window disclosed by the utility model, the punched rain shielding plate is arranged in the middle part, so that the louver window can be used in a windy and rainy environment, and a good rain shielding effect is achieved; the louver window also has the characteristics of damping, ventilation, rain shielding and bird and pest proofing; the whole structure is made of metal material, the sound deadening capacity is greater than 15dB (A), and the ventilation quantity is greater than 70%.
Description
Technical field
The utility model belongs to Control Noise Pollution technical field, relates to specifically a kind of noise elimination ventilation shutter.
Background technology
When the generating set of factory is worked, the heat and the pernicious gas that produce can be deposited in factory building, the healthy of the power of generating set and personnel worked the mischief, in order to address the above problem, conventionally on factory building, have ventilation opening, because this kind of ventilation opening do not have sound insulation function, the noise that generating set is produced propagates into the external world in large quantities, make periphery be subject to noise pollution, work and living environment are damaged, harm staff and periphery resident's is healthy.And the people that along with industry and the developing rapidly of traffic, that noise pollution is being puzzled just is day by day overlooking, city's section and factory district are passed through in commercial area, railway.Above problem all adopts noise elimination blinds to solve conventionally; noise elimination blinds is again shutter style silencer or noise reduction shutter; blinds sound absorber is actually the remodeling of the very short chip of a kind of length or folded plate type sound absorber; it is that a kind of permission air-flow passes through; and can eliminate the window formula structure of noise; but noise elimination blinds design of the prior art is unreasonable; structure is more complicated; ventilation noise reduction is not ideal enough; and under wind and rain environment; because wind action often can pour into rainwater indoorly, make the unit of charged work have potential safety hazard.
Summary of the invention
The deficiency that the utility model exists in order to overcome prior art, provides a kind of simplicity of design, rational in infrastructure, the effect of the keeping off the rain ventilation shutter of eliminating the noise preferably.
The utility model is achieved through the following technical solutions: a kind of noise elimination ventilation shutter, comprise bracing frame, the parallel equally spaced multi-disc noise elimination louvre blade that is provided with on bracing frame, every noise elimination louvre blade all forms by horizontal blinds parallel to the ground with the oblique blinds that ground is 45° angle, laterally blinds is arranged at shutter inner side, oblique blinds is arranged at shutter outside, laterally between blinds and oblique blinds, is being provided with a punching weather shield perpendicular to the ground; Laterally blinds comprises horizontal upper plate and horizontal lower plate, between plate and horizontal lower plate, be provided with horizontal soundproof course in the horizontal, oblique blinds comprises oblique upper plate and oblique lower plate, between oblique upper plate and oblique lower plate, be provided with oblique soundproof course, laterally in soundproof course and oblique soundproof course, be all filled with acoustical cotton.
Laterally upper plate and horizontal lower plate are ultramicropore metallic panel absorber, and oblique upper plate is light face metal sound barrier, and oblique lower plate is ultramicropore metallic panel absorber.
The material of punching weather shield, ultramicropore metallic panel absorber and light face metal sound barrier is aluminium alloys, stainless steel or galvanized steel plain sheet.
The aperture of punching weather shield is 0.5～1.5mm, and the aperture of ultramicropore metallic panel absorber is 0.2～0.6mm.
Noise elimination ventilation shutter of the present utility model can be used for the shutter of mansion, traffic noise sound barrier of the noise reduction of generating set, cooling tower noise reduction, the noise reduction of Ventilator Room, the sound insulation enclosure of blower fan, transformer station's noise reduction, freezing unit noise reduction, air-conditioning unit noise reduction and residential quarters etc.Noise barrier and the Landscape Style that when the utility model is applied to residential quarter noise reduction, noise elimination ventilation shutter can be made merge; be made into the form of enclosure wall; for residential quarters or villa district making into blinds noise barrier to measure; it has the feature of sound insulation, sound absorption, view, antitheft and protection villa district privacy; outward appearance is beautiful; coordinate mutually with surrounding environment, do not affect daylighting, in noise reduction, can also increase the sales volume of house property.
The beneficial effects of the utility model are: noise elimination ventilation shutter of the present utility model, owing to thering is the punching weather shield at middle part, so can use under wind and rain environment, the effect of keeping off the rain is better, it also has the feature of noise elimination, ventilation, rainproof, anti-bird worm, overall structure is made by metal material, and sound deadening capacity is greater than 15dB(A), ventilation is greater than 70%.The utility model can adopt the quality materials such as stainless steel, fine aluminum alloy, galvanized steel plain sheet to make according to the demand of environment for use, special architectural feature can be used under any weather conditions in addition, and gas-flow resistance is little, sound deadening capacity is large, and good looking appearance can doublely be done decoration window; Its length and thickness are all very little, have certain soundproof effect, can unite two into one with vent window, can also be assembled into large-scale blind integrated.The dimensions of shutter can form a series of standard specification by modulus size, and louvre blade is by rationally arranging the radiation of attenuate acoustic noise, and noise elimination frequency band is wider, can meet ventilation and heat, daylighting, goes along with sb. to guard him and control noise to extraradial requirement.
