Abstract
The utility model discloses a novel soundproof cover. The novel soundproof cover comprises a cover body for covering a noise source inside the cover body, and is characterized in that the cover body is successively composed of a steel orifice plate, sound absorbing materials and a housing from inside to outside, the cover body is provided with through holes, ventilation silencers are disposed at positions of the through holes, a position, corresponding to a pipeline passing through the cover body or other barriers, of the cover body is provided with an barrier opening, and damping sound absorbing materials are disposed at the position of the barrier opening. The novel soundproof cover is good in heat dissipation performance and convenient to move and maintain.
Description
Technical field
The present invention relates to a kind of sound insulation device, relate in particular to the acoustic hood of noise source shielding.
Background technology
In numerous occasions, especially, in workshop, the phenomenon of indivedual noise sources is relatively concentrated or only have to common noise source, as motor, water pump, blower fan, compressor and diesel engine etc.In the case, noise source can be enclosed in a cover, noise is seldom spread out of, with this, eliminate or reduce the interference of Noise upon Environment, this oise damping means is called acoustic hood.
Ventilation when traditional acoustic hood is not considered operation of electromechanical, heat dissipation problem, simultaneously because structure is single, install acoustic hood and can make troubles to maintenance, operation, supervision etc., and being therefore badly in need of a kind of new technology solves the problems referred to above.
Utility model content
The purpose of this utility model is the deficiency for above-mentioned traditional acoustic hood, provides a kind of and can effectively reduce noise, and be convenient to remove and install, and meets the Novel acoustic hood of the demands such as operation, supervision, temperature control.
For achieving the above object, the technical scheme that the utility model adopts is:
Novel acoustic hood, comprise noise source is covered in to inner cover body, it is characterized in that: described cover body from-inner-to-outer is comprised of steel orifice plate, acoustic absorbant and shell successively, wherein, described cover body is provided with through hole, described through hole is provided with ventilation silencer, and described cover body is provided with obstacle opening corresponding to pipeline or other barrier places through cover body, and described obstacle opening part is provided with damping acoustic absorbant.
Preferably, described cover body is split assembled structure, and each several part stitching portion is provided with damping acoustic pad, prevents the resonance coincidence effect of acoustic hood.
Preferably, offer access door, sound insulation view window and temperature control display system on described cover body, described cover body bottom is provided with universal wheel.
By above technical scheme, the beneficial effects of the utility model are:
1, by corresponding to equipment into and out of air port, on cover body, correspondence is provided with through hole, and in through hole, inlet and outlet ventilation silencer is housed respectively, can meet like this requirement of equipment noise reduction, also can guarantee equipment cooling demand, guarantee the serviceable life of sound source device;
2, cover body adopts split splicing structure, and is provided with soundproof door, view window, temperature control display system, facilitates repair and maintenance, and universal wheel is equipped with in cover body bottom, facilitates cover body to move;
3, the damping acoustic pad arranging by cover body stitching portion, and with damping acoustic absorbant, carrying out environmental sealing through the pipeline of acoustic hood and the obstacle opening part of other barriers, both can avoid each assembly of cover body and cover body itself to contact with the rigidity of pipeline, can prevent again that sound from passing slit source sound.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the cut-open view of Fig. 1.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
As shown in Figure 1, Novel acoustic hood, comprise the cover body 1 that noise source is covered in to inner split type splicing structure, cover body 1 each several part stitching portion is provided with damping acoustic pad, prevent the resonance coincidence effect of acoustic hood, cover body 1 from-inner-to-outer is successively by steel orifice plate 2, acoustic absorbant 3 and shell 4 form, wherein on cover body 1, in close equipment, enter, air outlet place offers through hole 5, through hole 5 places are provided with ventilation silencer 6, the sound deadening capacity of ventilation silencer 6 and the sound-insulation value of acoustic hood match, on cover body 1, offer access door 7, sound insulation view window 8 and temperature control display system 9, cover body 1 bottom is provided with universal wheel 10, and cover body 1 offers obstacle opening 11 at pipeline or other barrier places through cover body 1, obstacle opening 11 places are provided with damping acoustic absorbant 12, to realize environmental sealing.
