Abstract
The utility model relates to an improved moving sound-insulation wall. The height of an outer frame body is divided into four layers that are respectively in a rectangular structure. The periphery is provided with a multi-layer hollow plastic frame body, on which plastic press bars are provided. Splicing fittings are also arranged on the frame body. The front is provided with a perforated plate with the perforated rate of 15-45%, and the interior is provided with two layers of honey comb-shaped noise-absorbing structures. A resonance vibration type noise-absorbing plastic film is arranged between the perforated plate and the two layers of honey comb-shaped structures, and fine pores are fully distributed on the noise-absorbing plastic film. The upper middle layer is in a transparent rectangular structure, and the upper end of the outer frame body is provided with a noise-absorbing cylinder whose internal structure is the same as the structure of the rectangular structure. A wheel set and a rotary table are arranged on a base. The utility model is used for acoustic barrier engineering, and the motion and the effective noise-absorbing and sound isolation effects can be exerted.
Description
The utility model relates to a kind of sound arrester, be specifically related to rectangle sound-absorbing tectosome that a kind of utilization resonance acoustical absorption film constituted and transparent sound-absorbing tectosome and outside the framework upper end sound-absorbing structure body of one cylindric sound-absorbing tube is installed.
Its material of abatvoix that traditional noise barrier of past is used is nothing more than porous materials such as the fine rock wool of glass fiber, ore deposit, aluminium matter fibers, and it is as follows that existing three kinds of abatvoixs that material constituted are at this point made a comparative descriptions:
1. glass fiber: though price is more cheap, but it can absorb the moisture content in the air when wet environment uses, and after long-term the use, the water content in the fiber can make sound-absorbing effect reduce significantly, simultaneously this fiber is easily become floating dust in the air by weathering embrittlement, causes second environmental pollution.
2. the fine rock wool in ore deposit: generally adopt asbestos in the majority, but its moisture resistance of this fiber is poorer than glass fiber, absorb the moisture content in the air after, can reduce sound-absorbing effect by a larger margin, simultaneously the also easy-weathering embrittlement of this fiber.
3. aluminium matter fiber: though it can solve moisture content and floating dust problem, price is high, generally all uses at special occasions, can't be commonly used.
In addition, past traditional type noise barrier only adopts the upright wall wall type, this kind noise barrier prevents main diffraction sound, only be that the enable voice path is elongated, and a kind of portable noise barrier is arranged in addition on the market, though it is very similar to the utility model, all adopt resonance acoustical absorption film and sound-absorbing barrel structure body to handle the problem of Noise insulati on or absorption, but when running into the ground out-of-flatness, sound-absorbing and soundproof effect obviously reduce, each several part frame equipment structure body adopts metal material not consider that again the metal species material is the good conductor of sound wave simultaneously, can't effectively completely cut off the overflowing of sound wave and let out problem, reduces result of use especially.
At above-mentioned shortcoming of the prior art, the purpose of this utility model is to provide a kind of rotating disk can effectively deaden laminar hollow plastic cement frame material and ground out-of-flatness more than the sound wave transmission time to hide the sound structure; And have and make the noise barrier that splices accessory that to do fast bindings between the two portable noise barriers.
For achieving the above object the utility model provide rectangle sound-absorbing tectosome that a kind of utilization resonance acoustical absorption film constituted and transparent sound-absorbing tectosome and outside the framework upper end sound-absorbing structure body of one cylindric sound-absorbing tube is installed.Its characteristics are to have used acoustics highly acoustical and sound insulation technology, with the combining structure of simple honeycomb plate and resonant sound-absorbing plastic film and sound-absorbing tube, allow the sound-absorbing of a large amount of disappearances of noise construct.Not only have high acoustic absorptivity, but the also variation of mat upper end sound-absorbing nozzle footpath size simultaneously improves the performance of sound-absorbing and sound insulation, makes under the various different noise occasions and all can bring into play the most effective soundproof effect.
