[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is made further explained below:
As shown in drawings, this utility model includes: cooling water tank 4, diesel engine assembly 5, air filtering core assembly
6, alternator assembly 7, chassis fuel tank 9 and low noise box assembly 10, cooling water tank 4, diesel engine assembly 5,
It is internal that air filtering core assembly 6, alternator assembly 7, chassis fuel tank 9 are placed in low noise box assembly 10, cold
But water tank 4, diesel engine assembly 5, alternator assembly 7 are sequentially connected with from left to right, cooling water tank 4, diesel oil
Machine assembly 5, alternator assembly 7 are arranged on chassis fuel tank 9, and it is total that air filtering core assembly 6 is installed in diesel engine
Becoming on 5, diesel engine assembly 5, alternator assembly 7 bottom are all equiped with amortisseur 8；Wherein, low noise audio amplifier
Assembly 10 includes casing and acoustical cotton 18, and acoustical cotton 18 is arranged at cabinet wall surrounding and inside top.
In this utility model, air filtering core assembly 6 connects smoke exhaust pipe 2, smoke exhaust pipe 2 end by corrugated tube 3
It is equiped with smoke evacuation deafener 1；Chamber door, chamber door and low noise audio amplifier it is provided with on low noise box assembly 10 front end face
Connected by hinge 11 between assembly 10, chamber door is equiped with door lock 12；Low noise box assembly 10 front end face
On offer air inlet 13 and oil filler 14, air inlet 13, oil filler 14 are arranged on the right side of chamber door, refuel
Mouth 14 is located at below air inlet 13, and low noise box assembly 10 front bottom end offers lifting mouth 15；Low noise
Box assembly 10 side is provided with Intelligent control cabinet 16, and Intelligent control cabinet 16 front end face is provided with scram button 17.
In this utility model, low noise box assembly has good noise reduction in noise control, according to noise
The distribution in source and Volume control, be divided into four control zones by noise control in casing, and according in different subregions
The feature of noise, is respectively adopted sound insulation in different control zones, absorbs sound and the noise control technique such as noise elimination；Thus
Under the conditions of box sizes is restricted, utilize limited space, it is achieved that bigger noise reduction, achieve
Good result.The biggest sound operationally can occur due to diesel generating set, and the generation of its noise is very
Complexity, divides from Producing reason and position, and Diesel Generator Noise can include following sections: row
Cigarette noise, mechanical noise, combustion noise, cooling fan and exhaust noise, air intake noise, electromotor noise.
Wherein, internal combustion engine exhaust noise district: i.e. internal combustion engine discharge flue, smoke evacuation noise is a kind of high temperature, height
The pulsating nature pneumatic noise of speed, is the part that in equipment acoustic noise, energy is maximum, composition is most, compares induction noise
And the mechanical noise of body radiation is much higher, is topmost ingredient in unit overall noise, also makes an uproar
The emphasis of acoustic control.Induction noise district: be primarily present unit mechanical noise, electromotor noise and pneumatic noise
Deng, owing to air inlet is passive air inlet, and present position is away from main noise source, noise level and other several districts phases
Ratio is relatively low, and the noise reduction of relative requirement is the least.Aircraft cabin noise control zone: aircraft cabin noise district is predominantly organic
Tool noise, electromotor noise and combustion in IC engine noise, but this district relatively closes so mainly considering noise
Sound insulation problem, to reduce the outside propagation of noise.Exhaust noise control zone: be mainly composed of exhaust noise,
Pneumatic noise, fan noise, mechanical noise and combustion in IC engine noise etc., this district's noise source is more, noise
Level is higher, and owing to unit uses strong-force exhaust cooling to add the outside propagation of noise, so the noise in this district
Control relatively difficulty.
In this utility model, the design of low noise box assembly is for effectively reducing equipment acoustic noise impact to external world,
Effectively block noise route of transmission and the closing space designed.When unit is positioned over box house, due to every
The technology such as audio technology, sound absorption, stops noise outwards to be propagated, noise control at casing by noise source effectively
Inside, thus reduce its impact to external world.Opacity technique is the direction of propagation making acoustic wave segment with acoustic isolater
Change, reflect, reflect and make the acoustic wave energy penetrating this object weaken, thus reduce making an uproar of acoustic isolater another side
Sound.
This utility model is not limited by above-mentioned embodiment, other any without departing from of the present utility model
The change made under spirit and principle, modify, substitute, combine, simplify, all should be the displacement of equivalence
Mode, within being included in protection domain of the present utility model.
