Abstract
The utility model relates to a silencing housing for vehicle-mounted diesel generator, which comprises an air inlet silencing channel, a radiator of the diesel generator set and an air exhaust silencing channel and is characterized in that an underbody air inlet is arranged at the air inlet silencing channel on the car housing bottom, an air exhaust silencing elbow is additionally arranged between the radiator and the air exhaust silencing channel, one end of the elbow is connected with the radiator of the diesel generator set and the other end is stretched into the air exhaust silencing channel. The underbody air inlet and the silencing elbow together with the air inlet silencing channel and the air exhaust silencing channel realize the functions of air intake, air exhausting and noise reduction. The utility model is simple in structure, eliminates the structural contradiction of a narrow and small car housing and the heat radiation and ventilation of the diesel generator set, and is suitable for various movable diesel generators, enables the equipment noise to reach the requirements of environmental protection, and greatly decreases the air intake resistance without louver, and prevents rainwater from flooding into the air inlet when vehicles are running in rain and wind weather, and guarantees stable noise elimination performance.
Description
The utility model relates to mechanical field, is applicable to various mobile diesel-drivens, particularly truck diesel alternator compartment noise reduction.
Now, general truck diesel alternator compartment noise reduction ventilation inlet is located at the side, adopts air grille, netted air port etc., and this mode has increased considerably the air intake resistance, the corresponding hush tube effective length that reduced; Special wind and rain weather, when operation, rainwater enters the air channel easily, causes the acoustic attenuation performance instability.Do not establish air draft noise elimination bend pipe between unit radiator and air draft noise elimination road now, directly enter air draft noise elimination road from the diffusing noise that appears of radiator, the noise elimination poor effect is difficult to reach environmental demands.
The purpose of this utility model is to provide a kind of structure, production technology simple to the public, rationally solved the contradiction of the narrow and small structure of heat dissipation ventilation and compartment of generator set, be applicable to various mobile diesel-engine generator, make the noise of equipment drop to 50～60 decibels of truck diesel alternator noise reduction sound compartments that reached environmental demands.
The technical solution of the utility model is finished like this.
The truck diesel alternator noise reduction compartment a kind of by ventilation inlet noise elimination road, diesel powerplant radiator, that air draft noise elimination road is formed is characterized in that at the bottom of the compartment that there is ventilation inlet at the bottom of the car at place, air intake noise elimination road, and radiator and air draft noise elimination road have additional air draft noise elimination bend pipe.Ventilation inlet, air draft noise elimination bend pipe, air intake noise elimination road and air draft noise elimination road are finished air intake, air draft, noise reduction jointly at the bottom of the car.
Described air draft noise elimination bend pipe, an end is connected with radiator, and the other end puts in air draft noise elimination road.
The utility model structure, production technology are simple, have solved diesel powerplant the contradiction with the narrow and small structure in compartment of ventilating of loosing, and are applicable to various mobile diesel-engine generator, make noise of equipment reach environmental protection requirement.Without louver, netted air port, reduced the air intake resistance significantly, when wind and rain weather moves, can prevent that rainwater from sucking the air channel, ensured the stable of acoustic attenuation performance; Under certain compartment size condition, increased noise elimination pipeline effective length than air port, side, compartment; Because the rational deployment in the compartment, the noise reduction of air draft noise elimination bend pipe is good, makes noise reduce to 50～60 decibels, thereby has reached the design-calculated purpose.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail, the utility model is not limited to the following examples.
Fig. 1 is the utility model forward sight structural representation.
Fig. 2 is the utility model I-I sectional structure scheme drawing.
Fig. 3 is the utility model II-II sectional structure scheme drawing.
Among the figure: 1, ventilation inlet; 2, air intake noise elimination road; 3, noise elimination bend pipe; 4, air draft noise elimination road; 5, diesel powerplant; 6, radiator; 7, compartment; 8, exhaust outlet; 9, generating cabin; 10, cable vault; 11, fuel tank; 12, smoke-discharging noise elimination device; 13, compartment sound insulation wall.
Fig. 1,2,3 is depicted as vehicle-mounted 30 diesel powerplants 5.Radiator on the diesel powerplant is called for short the unit radiator.As can be seen from Figure 2 the compartment be provided with that ventilation inlet 1 at the bottom of the car, air intake noise elimination road 2, electromagnetism are fixed 10, fuel tank 11, generating cabin 9, diesel powerplant 5, generating unit radiators 6, smoke-discharging noise elimination device 12, air draft noise elimination bend pipe 3, air draft noise elimination road 4, compartment sound insulation wall 13.
The direction of arrow is for advancing the air draft trend among Fig. 1, ventilation inlet 1 is in air intake noise elimination road 2 ventilation inlets at the bottom of the compartment at the bottom of the car, ventilation inlet 1 makes air intake noise elimination road 2 and compartment 7 exterior at the bottom of the car, ventilation inlet 1 enters air intake sound channel 2 at the bottom of the car, enter the heat that generating cabin 9 and diesel powerplant 5 and diesel-engine generator heat sink radiates go out again, after the wind of the making an uproar exchange, enter air draft noise elimination bend pipe 4, it is contained in 4 in diesel-engine generator radiator 6 and air draft noise elimination road, one end is connected with diesel-engine generator radiator 6, one end puts in air draft noise elimination road 4, it has increased de-noising and air draft effect, make the noise of equipment reduce to 50～60 decibels, reached environmental demands, and then entered air draft noise elimination road 4, discharged outside the compartment 7 from exhaust outlet 8 at last.
Claims (2)
