The advantages are that: the utility model discloses can effectively completely cut off the produced noise of diesel engine, avoid noise pollution and cooling effect preferred.
Description
Technical Field
The utility model belongs to the technical field of the diesel engine box, especially, relate to a diesel engine silence holding case.
Background
At present, most diesel engines are stored in a box body in use, so that the diesel engines are protected and have certain sound insulation effect; the existing box body has two structures, one is a complete sealing structure, although the noise reduction effect is good, the heat generated by the engine due to work cannot be effectively discharged, so that the internal temperature is too high; the other is to leave a ventilation opening on the box body, but the structure can cause noise generated by the operation of the engine to be transmitted to the outside through the ventilation opening, so that noise pollution is caused.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art existence, provide a diesel engine silence holding case, it has the produced noise that can effectively completely cut off diesel engine, avoids noise pollution and the characteristics of cooling effect preferred.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a silence containing box of a diesel engine comprises a box body, wherein the box body is composed of a frame and a fixing plate, and the fixing plate is packaged on an opening of the frame; the box body is internally provided with a component mounting part; the air inlet sound insulation channel is arranged on the box body, and the structure of the air inlet sound insulation channel is as follows: the ventilation board is provided with a ventilation opening and a sound insulation part, the ventilation opening on the adjacent ventilation boards is opposite to the sound insulation part, and a certain gap is formed between the ventilation openings; an air inlet is formed in the box body, and the air inlet is opposite to the sound insulation part; and a centrifugal exhaust fan is arranged in the box body.
The number of the ventilation plates is three.
The ventilation opening is extended with a partition plate, and the other end of the partition plate is abutted to the sound insulation part of the adjacent ventilation plate.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the ventilation openings on the ventilation board are arranged in a staggered way, so that external wind flow can enter the box body through the wind channel in use, and internal noise can be isolated by the sound insulation part, thereby avoiding noise from being transmitted to the outside and effectively avoiding noise pollution; meanwhile, the centrifugal exhaust fan can centrifugally exhaust hot air, noise can be refracted and silenced in the centrifugal exhaust fan, and the noise is prevented from being transmitted outwards while internal heat is exhausted.

Fig. 2 is the structural schematic diagram of the air intake sound insulation channel of the present invention.
Fig. 3 is a schematic structural view of the ventilation board of the present invention.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1 and 3: a silence containing box of a diesel engine comprises a box body 10, wherein the box body 10 is composed of a frame and a fixing plate 11, the frame is of a square structure under general conditions, and the fixing plate 11 is packaged on an opening of the frame. The fixed plate 11 has a plurality of component mounting portions, pipe mounting ports, and windows for facilitating the mounting and subsequent maintenance of components. Have air inlet sound insulation passageway on box 10, the structure of air inlet sound insulation passageway is: the ventilation board 12 is provided with a vent 13 and a sound insulation part 14, the vent 13 on the adjacent ventilation board 12 is opposite to the sound insulation part 14, a certain air passing gap is formed between the adjacent ventilation boards 12, and an air channel is formed in the gap; an air inlet 15 is formed in the fixed plate 11, and the air inlet 15 is opposite to the sound insulation part 14; through the structure arrangement, external wind flow enters the air channel through the air inlet 15, and finally enters the box body 10 from the innermost ventilation opening 13 through the flow direction of the air channel; meanwhile, because the sound is transmitted in a straight line, the noise generated by the diesel engine cannot be transmitted to the outside through the blocking of the sound insulation part 14, and the noise pollution is avoided. In general, the number of the ventilation board 12 is three or four. The partition plate 17 extends from the vent hole 13, and the other end of the partition plate 17 abuts against the sound insulation part 14 of the adjacent vent plate 12, so that the air flow entering from the air inlet 15 has a corresponding air channel flow direction on the corresponding vent hole 13, and the air flow is prevented from channeling in the air channel. A centrifugal exhaust fan is arranged in the box body 10, the centrifugal exhaust fan is positioned right opposite to the ventilation opening 13, and an air inlet on the centrifugal exhaust fan is opposite to an air outlet of the diesel engine, so that hot air can be directly absorbed conveniently; and after absorbing hot air, the turbine in the centrifugal exhaust fan can centrifugally change the direction of the hot air and discharge, and the internal noise can be refracted and silenced in the turbine, so that the internal noise is prevented from being transmitted to the outside.
The centrifugal fan 16 is widely used at present, and other structures and principles are the same as those in the prior art, and are not described in detail here.
