Description
Technical field
This utility model is related to ventilating and noise decreasing device, more particularly to a kind of ventilating and noise decreasing device of diesel-driven generator cabinet.
Background technology
Diesel generating set is a kind of generator assembly with diesel oil as fuel, as the combustion characteristics of diesel oil sends out diesel oil
Larger noise and heat that group of motors is produced when working, are covered with a machine outside diesel generating set for security consideration
Case.It is at present main by water tank and shock absorber are arranged in diesel generating set cabinet absorbing most of diesel-driven generator work
When the noise that produces and heat.Air channel case is additionally provided with typically near water tank side in cabinet, air channel box top is provided with aerofluxuss
Hole, is provided with radiator fan in the case of air channel, accelerates radiating by the radiator fan in the case of air channel, but is discharged by radiator fan
Steam can produce air draft noise, and the noise in cabinet can also pass through outside the cabinet of steam vent propagation of air channel box top in addition, make
Into noise pollution.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of ventilating and noise decreasing device of diesel-driven generator cabinet, energy
The soundproof effect and radiating effect of diesel-driven generator cabinet are enough taken into account, noise in diesel-driven generator cabinet is reduced and is outwards propagated.
For achieving the above object, this utility model employs technical scheme below：Including cabinet, air channel case and ventilating and noise decreasing
Device, the air channel case are connected with cabinet side, and the air channel box top offers an opening, the ventilating and noise decreasing device
It is fixedly connected on opening, the ventilating and noise decreasing device includes casing, and the casing top offers a plurality of louvres, described
A plurality of left acoustical panels and a plurality of right acoustical panels, a plurality of left noise reductions are respectively arranged with two medial wall of left and right of casing
Plate and the interlaced length that arrangement, the adjacent left acoustical panel of any two and right acoustical panel are set of a plurality of right acoustical panels
With the width more than box inside.
By adopting preceding solution, the beneficial effects of the utility model to be：A left side is provided with the inside of ventilating and noise decreasing device
Acoustical panel and right acoustical panel, acoustical panel can cut down significantly the energy of noise, and left and right acoustical panel using loose porous material
It is interlaced that arrangement is set, propagation distance of the sound wave in ventilating and noise decreasing device is increased, reduction sonic transmissions are on the outside of cabinet
Energy.Heat dissipation channel is formed between adjacent left and right acoustical panel, the radiating effect of cabinet is not affected.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic cross-section of this utility model ventilating and noise decreasing device.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, illustrated embodiment is served only for explaining this reality
With new, scope of the present utility model is not intended to limit.
A kind of ventilating and noise decreasing device of diesel-driven generator cabinet with reference to shown in Fig. 1, including cabinet 1, air channel case 2 and ventilation subtract
Make an uproar device 3, the air channel case 2 is connected with 1 side of cabinet；An opening 21, the ventilation are offered at the top of the air channel case 2
Noise-decreasing device 3 is fixedly connected on opening 21.
With reference to shown in Fig. 2, the ventilating and noise decreasing device 3 includes that casing 31, a plurality of right acoustical panels 33 and an a plurality of left sides disappear
Soundboard 34, offers a plurality of louvres 32 at the top of the casing 31, the right acoustical panel 33 and left acoustical panel 34 are by loose more
The vitreous fibre material in hole is made, with good sound-absorbing effect.A plurality of right acoustical panels 33 are equidistant uniform respectively
It is arranged on the right side inwall of casing 31, a plurality of left acoustical panels 34 are equidistantly uniformly arranged at the left side of casing 31 respectively
On inwall, the length of adjacent right acoustical panel 33 and left acoustical panel 34 and more than the width on the inside of casing 1, a plurality of right sides disappear
Soundboard 33 is interlaced with a plurality of left acoustical panels 34 to arrange the multiple heat dissipation channels for turning back of arrangement form, increased the biography of sound wave
Distance is broadcast, has cut down energy of the sonic propagation to outside cabinet.
Although specifically showing and describing this utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model can be made a variety of changes, be protection domain of the present utility model.
