Abstract
The utility model relates to a power source the car especially relates to a supply vehicle is aired exhaust and is fallen structure of making an uproar. A supply vehicle is aired exhaust and is fallen structure of making an uproar, includes chassis car, carriage and generating set, and the carriage has set up the passageway of airing exhaust, and the passageway of airing exhaust is installed and is cut off and air exhaust the baffle, the shutter of airing exhaust is installed at the carriage rear portion. The baffle of airing exhaust there is a plurality of, install cable reel in the carriage. Compared with the prior art, cut off and air exhaust the baffle through installing additional, eliminated gas reflux, the air current passageway circulation of airing exhaust more easily, the baffle reduces the noise that the air current was carry over out of through airing exhaust.

Description
Technical field
This utility model relates to a kind of supply vehicle, particularly relates to a kind of supply vehicle air draft denoising 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.Air-flow is driven to be discharged by anechoic chamber 4 rearwardly shutter 7 as it is shown in figure 1, generating set 3 is air-cooled by unit cooling fan.Reach the purpose of cooling unit.
But, when air-flow is by anechoic chamber 4, owing to capstan winch dividing plate 5 blocks major part air-flow, it is easy to gas backstreaming phenomenon occurs, causing that gas circulation is obstructed, expellant gas noise does not obtain sound-absorbing and damping, causes that supply vehicle afterbody noise is bigger.
Summary of the invention
Based on this, this utility model is in order to air-flow can pass through air exhaust passage, and the gas noise given off is absorbed and damping, thus reducing the purpose of afterbody noise, spy devises a kind of supply vehicle air draft denoising structure.
This utility model solves its technical problem and the technical scheme is that a kind of supply vehicle air draft denoising structure, including chassis, compartment and generating set, described compartment is provided with air exhaust passage, and described air exhaust passage is provided with partition and air draft guide plate, and rear portion, described compartment is provided with air draft shutter.
A kind of supply vehicle air draft denoising structure, described air draft guide plate has several.
Compartment is provided with cable hoist.
The beneficial effects of the utility model are in that: by installing partition and air draft guide plate additional, eliminate gas backstreaming, and air-flow is easier to circulate at air exhaust passage, reduces, by air draft guide plate, the noise that air-flow is taken out of.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model background technology；
Fig. 2 is the structural representation that this utility model relates to a kind of supply vehicle air draft denoising structure.
As it is shown in figure 1, wherein, 1 it is chassis, 2 is compartment, 3 is generating set, 4 is anechoic chamber, 5 cuts off for capstan winch, 6 is cable hoist, 7 be afterbody shutter, arrow is air flow direction.
As in figure 2 it is shown, wherein, 11 be chassis, 12 be compartment, 13 be generating set, 14 be air exhaust passage, 15 be air draft guide plate, 16 for cutting off, 17 be cable hoist, 18 be air draft shutter, arrow be air flow direction.
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 in figure 2 it is shown, a kind of supply vehicle air draft denoising structure, including chassis 11, compartment 12 and generating set 13, compartment 12 is provided with air exhaust passage 14, and air exhaust passage 14 is provided with partition 16 and air draft guide plate 15；Rear portion, compartment 12 is provided with air draft shutter 18.
Described air draft guide plate 15 has several.
In described compartment 12, cable hoist 17 is installed.Cable hoist 17 configures frequency-variable controller, and possess automatically and manually operating function to be wound folding and unfolding cable.
The supply vehicle compartment 2 that this utility model relates to firmly is connected with chassis 1, and generating set 3 is arranged in compartment 2.When air-flow is by air exhaust passage 14, cut off 16 air-flow upwards water conservancy diversion, when air-flow runs into air draft guide plate 15, the noise taken out of by the sound absorber confrontation air-flow arranged on air draft guide plate 15 carries out sound-absorbing and damping, discharge finally by air draft shutter 18 is outside to compartment 12, so can eliminate gas backstreaming, reduce the noise that air-flow is taken out of simultaneously.
Adopt this air draft denoising structure, it is possible to meet the good running environment of generating set 3, give full play to the Emergency use of supply vehicle, save the energy simultaneously, 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.
Claims (3)
1. a supply vehicle air draft denoising structure, including chassis, compartment and generating set, it is characterised in that: described compartment is provided with air exhaust passage, and described air exhaust passage is provided with partition and air draft guide plate；Rear portion, described compartment is provided with air draft shutter.
2. a kind of supply vehicle air draft denoising structure according to claim 1, wherein, described air draft guide plate has several.
