Modern society is more and more stronger to the dependence of electric power, and various electric equipments need the stable supply of electric power that continues, and is especially commercial, bank, hospital facility.But because energy scarcity and peak of power consumption undersupply often have and stop powering-off state.Generating set this moment power supply has in support guaranteed the normal operation of equipment.But it is very big to produce noise during generating set work, has directly influenced people's work and life, and market presses for the as far as possible little generating set of noise.The air inlet muffler is an important device of improving the quiet case anti-acoustic capability of generating set.
The air intake muffler of existing generating set casing mostly is positioned at casing side or end, has bulky, defectives such as noise reduction is not good, dust tightness difference.
The content of utility model
The utility model is at huge, the shortcomings such as noise reduction is not good, dust tightness difference of air intake muffler volume of existing generating set casing, having carried out research improves, a kind of jacking wind muffler is provided, easy for installation, have rainproof, ventilation, noise reduction, function such as dustproof.
The technical solution of the utility model is as follows:
A kind of jacking wind muffler comprises bucket body 6, and bucket body 6 upper ends are air inlet 9, and the side, lower end is an air outlet 10; Oblique arrangement is in air inlet 9 at interval for sound-absorbing sheet 4, and sound-absorbing sheet 7 tilts to place air outlet 10.
Its further technical scheme is:
Described sound-absorbing sheet 4 is plate-air-perforated plate construction.
Described sound-absorbing sheet 7 is porous plate-air-perforated plate construction.
Described bucket body 6 upper ends and cover plate 1, supporting bracket 2 are connected through the hinge; When cover plate 1 is opened, support by supporting bracket 2; When cover plate 1 was closed, supporting bracket 2 placed above the sound-absorbing sheet 4.
When described cover plate 1 is opened and sound-absorbing sheet 4 be the angle of inclination.
Described bucket body 6 bottoms are provided with water storage tank 8, and water storage tank 8 belows connect drainage pipe 5.
Described bucket body 6 upper end air inlets 9 places are provided with sealing mouth 3.
Around the described bucket body 6 is flange arrangement.
Useful technique effect of the present utility model is:
The utility model is installed on the casing top of generating set, compact conformation, and volume is less, in abundant reasonable use generating set upper space, also solves the noise leakage problem of unit effectively.Adopt flange arrangement, easy for installation.
The utility model incoming air area is big, excellent noise reduction effect, and has rainproof, dust reduction capability.By test and actual the use, can drop to below the 75db complete environmentally acceptable requirement for the air inlet noise of medium-sized generating set.It is good to be widely used in requirement noise-reducing and dustproof performance, and requires the air intake sound-attenuating system of the big generating set casing of incoming air area.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is the main pseudosection of the utility model when cover plate is opened.
As shown in Figure 1, jacking wind muffler of the present utility model comprises bucket body 6, and bucket body 6 upper ends are air inlet 9, and the side, lower end is an air outlet 10; Sound-absorbing sheet 4 oblique arrangement at interval adopts plate-air-porous plate sound absorption structure in air inlet 9, and sound absorption structure thickness is 30mm, and the filling porous sound-absorbing material of air layer, this material are rock wool, and acoustic absorptivity is 0.8, has functions such as rainproof, ventilation, noise reduction; Sound-absorbing sheet 7 tilts to place air outlet 10, and sound-absorbing sheet 7 is 20 degree with the angle of horizontal direction in the present embodiment, adopts porous plate-air-porous plate sound absorption structure, and air layer is filled rock wool, has more effectively played functions such as sound insulation, sound absorption, noise elimination.
Described bucket body 6 upper ends and cover plate 1, supporting bracket 2 are connected through the hinge; Described cover plate 1, supporting bracket 2 are mobilizable, when cover plate 1 is opened, by supporting bracket 2 support fixation, the cover plate 1 at top and the supporting bracket of two sides 2 form the inlet scoop of rain-proof types, cover plate 1 opening angle is between 20～25 degree, and concrete angle is determined by the air channel available ventilation area that sound-absorbing sheet 4 forms; When generating set quits work or time spent not for a long time, supporting bracket 2 is packed up and is placed above the sound-absorbing sheet 4, and cover plate 1 is closed, and puts down to place on the sealing mouth 3.
Be the reversed dip angle with sound-absorbing sheet 4 when described cover plate 1 is opened, the angle when open with cover plate 1 in the air channel that is formed by sound-absorbing sheet 4 is that 65～75 to spend be the best, and specifically the angle number of degrees determine according to the equipment acoustic noise situation.
Arrow is the direction of wind path among Fig. 1.
Described bucket body 6 bottoms are provided with water storage tank 8, and water storage tank 8 belows connect drainage pipe 5, and the rainwater that enters bucket body 6 flows into the water storage tank 8 of its bottom, discharges outside the casing through drainage pipe 5, efficiently solves the rainproof problem of casing.
