Abstract
The invention relates to a dentoid panel double-cavity sound absorption and insulation screen which can decrease noise. The dentoid panel double-cavity sound absorption and insulation screen comprises a porous panel which is connected with a sound insulation back plate; the surface of the porous panel is of a dentoid structure; a separation plate is arranged between the porous panel and the sound insulation back plate; a front separation cavity is formed between the separation plate and the porous panel; a rear separation cavity is formed between the separation plate and the sound insulation back plate; and a sound absorption material is arranged in the front separation cavity. The dentoid panel double-cavity sound absorption and insulation screen is applicable to various indoor and outdoor sound absorption and noise lowering places.
Description
Technical field
The present invention relates to sound absorption reduction environmental protection field, relate in particular to a kind of sound absorbing-insulating body.
Background technology
Along with the enhancing day by day of people's environmental consciousness, more and more higher to the requirement that reduces noise.The method of now general reduction noise is to adopt the sound absorbing-insulating body, especially all adopts the sound absorbing-insulating body in the road both sides that need reduction traffic noise disturbs.As shown in Figure 3, the common structure of sound absorbing-insulating body is at present: comprise porous panel 1, porous panel 1 is connected with sound insulation backboard 2, forms a cavity between porous panel 1 and the sound insulation backboard 2, and cavity inside is provided with sound absorption material 3.Its shortcoming is: because porous panel is a plane structure, is reflected easily when sound wave touches porous panel, thereby causes the sound absorption effect poor; Have only a cavity between porous panel and the sound insulation backboard in addition, sound wave penetrates easily, can make the sound absorption deleterious equally.
Summary of the invention
Technical problem to be solved by this invention is: a kind of sound absorption effect Dentoid panel double-cavity sound absorption and insulation screen preferably is provided.
For addressing the above problem, the technical solution used in the present invention is: Dentoid panel double-cavity sound absorption and insulation screen, comprise porous panel, porous panel is connected with the sound insulation backboard, the surface of described porous panel is a dentalation, is provided with dividing plate between porous panel and the sound insulation backboard, separate space before forming between described dividing plate and the porous panel, form the back separate space between dividing plate and the sound insulation backboard, described preceding separate space inside is provided with sound absorption material.
Described sound absorption material is a noise elimination glass wool body, and the outer wrap of described noise elimination glass wool body has alkali-free hydrophobic glass cloth.
The material of described porous panel and sound insulation backboard is fiber glass resin.
The invention has the beneficial effects as follows: the present invention adopts the dentation porous panel, is not easy to be reflected when sound wave touches the dentation porous panel, thereby makes most of sound wave all enter the sound absorbing-insulating body, has improved the sound absorption effect; The present invention adopts two-chamber in addition, makes sound wave be not easy to be penetrated, and has further improved the sound absorption effect.

Among Fig. 3: 1, porous panel, 2, the sound insulation backboard, 3, sound absorption material.
The specific embodiment
Below in conjunction with accompanying drawing Dentoid panel double-cavity sound absorption and insulation screen of the present invention is described in further detail.
As Fig. 1, shown in Figure 2, Dentoid panel double-cavity sound absorption and insulation screen, comprise porous panel 1, porous panel 1 is connected with sound insulation backboard 2, the material of described porous panel 1 and sound insulation backboard 2 is fiber glass resin, the surface of described porous panel 1 is a dentalation, be fixed with dividing plate 3 between porous panel 1 and the sound insulation backboard 2, separate space 4 before forming between described dividing plate 3 and the porous panel 1, form back separate space 5 between dividing plate 3 and the sound insulation backboard 2, separate space 4 inside are filled with sound absorption material before described, described sound absorption material is a noise elimination glass wool body 6, and the outer wrap of described noise elimination glass wool body 6 has alkali-free hydrophobic glass cloth 7, and alkali-free hydrophobic glass cloth 7 is not when hindering sound wave to penetrate into noise elimination glass wool body 6, can prevent fog again, rainwater etc. enter noise elimination glass wool body 6, influence the acoustically effective of noise elimination glass wool body 6.
Operating principle of the present invention is: when sound wave touches porous panel 1, because the surface of porous panel 1 is a dentalation, sound wave is not easy to be reflected, thereby separate space 4 before most of sound wave is all entered by the through hole on the porous panel 1, then the noise elimination glass wool body 6 by separate space 4 inside before being filled in absorbs, the unabsorbed sound wave of fraction penetrates dividing plate 3 and enters back separate space 5, this moment, the energy of sound wave was weakened greatly by dividing plate 3 and back separate space 5, when sound wave touches sound insulation backboard 2, the energy of sound wave is weakened again greatly, and the sound wave that can penetrate sound insulation backboard 2 can be ignored substantially.From the above, the present invention compares with traditional sound absorbing-insulating body, and the sound absorption effect is better.
Claims (3)
