Description
Technical field
This utility model relates to a kind of supply vehicle, particularly relates to a kind of supply vehicle air draft noise-reducing structure.
Background technology
At present, supply vehicle being fitted with the generating set of emergency repair operation, when generating set runs, blower fan can produce powerful air-flow to lower the temperature unit and to complete gas exchange.Existing supply vehicle air intake/outtake system rotates generation negative-pressure air-suction by the fan of generating set self and discharges heat.As shown in Figure 1: 1 is chassis；2 is advancing air shutter；3 is compartment；4 is side air feed shutter window；5 is generating set；6 is side air draft shutter；7 is cable hoist；8 is rear air draft shutter.Generating set is air-cooled is cooled down fan drive air-flow by two grades of anechoic chambers to side air draft shutter and the discharge of rear air draft shutter by unit, reaches the purpose of cooled electric generator group.
Existing city electrical equipment gets more and more, the generating set power of power supply vehicle of meet an emergency is required more and more higher, to enter air draft shutter more because of surrounding to cause supply vehicle, and shutter has certain angle downward when opening, thus cause that the propagation angle of sound is downward, when air-flow is by two grades of anechoic chambers, expellant gas noise does not obtain sound-absorbing and damping causes that vehicle periphery noise is bigger.
Summary of the invention
Based on this, this utility model is to solve the configuration of Electricity Generation unit air intake/outtake system shutter and the problem reducing vehicle periphery noise, the gas noise given off is absorbed and damping, thus reducing afterbody noise, spy devises a kind of supply vehicle air draft noise-reducing structure.
This utility model solves its technical problem and the technical scheme is that a kind of supply vehicle air draft noise-reducing structure, including chassis, compartment, generating set and air feed shutter window, it is characterised in that: described compartment is provided with air intake silencing baffles；Described compartment arranges silencers channel, and described silencers channel is provided with air draft silencing baffles and sound-absorbing deflector, and described silencers channel top has discharge window, and is provided with top cover and strut in discharge window.
A kind of supply vehicle air draft noise-reducing structure, wherein, described air intake silencing baffles and air draft silencing baffles have several.
Described silencers channel is provided with drain pipe.
Described strut is electronic strut.
Described compartment is provided with cable hoist.
The beneficial effects of the utility model are in that: this utility model realizes easily, Practical Performance is good, the quantity of vehicle periphery shutter can be decreased, by installing silencing baffles and sound-absorbing deflector additional, and have discharge window at car body top, make gas be easier to circulation, reduce the noise that air-flow is taken out of, reduce the noise of vehicle's surroundings.

Detailed description of the invention
Illustrating below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
As shown in Figures 2 and 3, a kind of supply vehicle air draft noise-reducing structure, including chassis 11, compartment 15, generating set 14 and air feed shutter window 12, compartment 15 is provided with air intake silencing baffles 13；Compartment 15 arranges silencers channel 16, and silencers channel 16 is provided with air draft silencing baffles 17 and sound-absorbing deflector 22, and silencers channel 16 top has discharge window, and is provided with top cover 18 and strut 19 in discharge window.
This supply vehicle air draft noise-reducing structure, wherein, air intake silencing baffles 13 and air draft silencing baffles 17 have several.
Silencers channel 16 is provided with drain pipe 21.
Strut is electronic strut.
Cable hoist 20 is installed in compartment 15.Cable hoist 20 configures frequency-variable controller, and possess automatically and manually operating function to be wound folding and unfolding cable.
Supply vehicle compartment 15 of the present utility model is firmly connected with chassis 11, and generating set 14 is arranged in compartment 15.Before generating set 14 prepares startup, open air feed shutter window 12 and open exhaust outlet top cover 18 by electronic strut 19；After generating set 14 starts, by the cooling fan of generating set 14 self, air is carried out extraction, air-flow enters silencers channel 16 by air feed shutter window 12 and air intake silencing baffles 13, at this moment 22 air-flow upwards water conservancy diversion of sound-absorbing deflector, when air-flow runs into air draft silencing baffles 17, the noise taken out of by sound absorber confrontation air-flow on air draft silencing baffles 17 carries out sound-absorbing and damping, discharges finally by discharge window is outside to compartment 15.
Owing to all having corresponding sound arrester entering air draft place, adopt this noise-reducing structure, its exhaust system is more smooth and easy, easily install, as rain enters into compartment 15 by exhaust outlet top cover 18, the drain pipe 21 arranged is by bottom the aqueous reflux that enters in compartment 15 silencers channel 16 to compartment 15, it is to avoid due to the damage that equipment is caused by internal hydrops.
Adopt this air draft noise-reducing structure, it is possible to meet the good running environment of generating set 14, give full play to the Emergency use of supply vehicle, save the energy, improve work efficiency.
Embodiment described above, the simply one of this utility model more preferably detailed description of the invention, the usual variations and alternatives that those skilled in the art carries out within the scope of technical solutions of the utility model all should be included in protection domain of the present utility model.
