Abstract
The utility model discloses a noise-absorbing board with a stepped hole structure, which is used to shield the noise coming from the two sides of railways, roads, urban viaducts, airports and various machines. The noise-absorbing board comprises a sound-absorbing board, a muffling board and a back panel. The noise-absorbing board has the following characteristics: the surface of the sound-absorbing board is provided with sound-absorbing tapered holes; the surface of the muffling board is provided with stepped muffling holes; transitional tapered holes are arranged between the front end of the first hole of each stepped muffling hole and each of the other holes; the inner end surface of each stepped muffling hole is provided with a taper; and sound wave-shunting boards are arranged between the wall of the last hole of the stepped muffling hole and the side of the taper. After entering into the transitional tapered holes, sound waves are reflected and refracted to form scattered and diffracted sound waves, and under the functions of the stepped muffling holes and the tapers and the wave-shunting boards in the stepped muffling holes, the sound waves bump into and counteract the sound waves which constantly enter in later, so that the sound waves can be gradually attenuated in the stepped muffling holes. The utility model has the advantages of simple and practical structure, easy cleaning, convenient mounting, low fabrication cost and good muffling effect.
Description
Technical field
The utility model relates to a kind of abatvoix, is used for the shielding that railway, highway, urban viaduct and both sides, airport and all kinds of machinery send noise.
Background technology
As everyone knows, noise pollution has become one of world today's public hazards, do not allowed us to ignore, at present, the most modes that adopt the acoustical cotton sound-absorbing of abatvoix, this sound-absorbing mode sound-damping qualities is low, volume is big, acoustical cotton is easily aging, easy cleaning, application life are short, and acoustical cotton also can cause secondary pollution to environment simultaneously.
Summary of the invention
The utility model purpose is in order to overcome the shortcoming and defect of existing abatvoix noise reduction mode, to have proposed a kind of shoulder hole structure abatvoix, substituting existing structure and material, the sound-absorbing amount and the application life of being intended to improve abatvoix.
Technical solution of the present utility model is achieved in that
A kind of shoulder hole structure abatvoix comprises abatvoix, sound insulation slab and rear board, it is characterized in that: described abatvoix plate face is provided with the sound-absorbing taper hole; Sound insulation slab plate face is provided with the hierarchic structure bloop, be provided with the transition taper hole between the front end in first hole of hierarchic structure bloop and each hole, hierarchic structure bloop inner face is provided with circular cone, be provided with the sound wave flow distribution plate between the hole wall in last hole of hierarchic structure bloop and the circular cone side, abatvoix, sound insulation slab and rear board are fixedlyed connected.
Described a kind of shoulder hole structure abatvoix is characterized in that: described sound-absorbing taper hole is distributed in the whole plate face of abatvoix.
Described a kind of shoulder hole structure abatvoix is characterized in that: described hierarchic structure bloop is distributed in the whole plate face of sound insulation slab.
Described a kind of shoulder hole structure abatvoix is characterized in that: the end of the circular cone that described hierarchic structure bloop inner face is provided with, overlap with hierarchic structure bloop inner face, and the bus of circular cone is on the extended line of last taper hole outline line of transition taper hole.
Described a kind of shoulder hole structure abatvoix is characterized in that: the sound wave flow distribution plate that is provided with between the hole wall in last hole of described hierarchic structure bloop and the circular cone side is along whole circumferentially uniform.
Described a kind of shoulder hole structure abatvoix, it is characterized in that: the hole count of described hierarchic structure bloop is 2～5.
Compared with prior art, the beneficial effects of the utility model are:
1, sound insulation slab of the present utility model is provided with between the front end in hierarchic structure bloop and first hole of hierarchic structure bloop and each hole and is provided with the transition taper hole, make sound wave generation reflection and refraction and form scattering and diffraction sound wave, sound wave by with the effect of hierarchic structure bloop and inner circular cone harmony ripple flow distribution plate thereof, sound wave head-on collision, counteracting with the later stage constantly imports into attenuate sound wave step by step in the hierarchic structure bloop; Thereby improved sound-damping qualities;
2, the utility model adopts the hierarchic structure bloop, substitutes existing structure and material, the application life of having improved abatvoix;
3, the utility model has the advantages that simple and practical, easy cleaning, easy for installation, low cost of manufacture, good muffling effect.
