The arbitrary and all combination of the Listed Items of pass.
Before the sound-insulation structure 10 in the present invention illustrates, the essential structure first to generating set is carried out
Brief explanation, in order to which the sound-insulation structure in the present invention is better understood.Wherein, casing includes the main tank being connected with each other
Body and side box body, the generator unit mainly include motor and generator, and motor is arranged in main box, and generator is arranged at side case
In vivo, motor output power, drives generator operation and output power.Specifically, the motor produces driving using fuel combustion
The energy of motor output end rotation, usually, main box need to have air inlet and exhaust outlet, and air ejector fan is provided with exhaust outlet,
To form an air current flow path, ensure the normal operation of motor.In addition, air-flow can also be taken away in being moved along air current flow path
Partial heat, the effect of radiating is played to motor and generator.But air-flow disengaging can produce noise, and motor and generator
Work can also produce noise, bring noise pollution, the sound-insulation structure in the present invention, can be before ensureing into, air draft smoothly
Put, play noise reduction, deadening.
As shown in figure 1, the sound-insulation structure 10 in an embodiment of the present invention, including casing (figure is not marked), maintenance door
Air intake assembly 12 and side air intake assembly (figure is not marked).
Maintenance door air intake assembly 12 is arranged at main box side, and maintenance door air intake assembly 12 includes being provided with the first air inlet
1222 maintenance door main body 122, cooperatively form the first door socket 124 of the first sound insulation chamber with maintenance door main body 122, and positioned at the
First inlet scoop 126 of one sound insulation chamber, the first inlet scoop 126 are arranged at maintenance door body 122 side, and with the first air inlet
1222 connections, the first sound insulation chamber also connect with main box.
Side air intake assembly, is arranged at side box body, and side air intake assembly includes the side shutter master provided with the second air inlet 1422
Body 142, cooperatively form the second door socket 144 of the second sound insulation chamber with side air intake door main body 142, and the positioned at the second sound insulation chamber
Two inlet scoops 146, the second inlet scoop 146 is arranged at the side of side air intake door main body 142, and is connected with the second air inlet 1422, the
Two sound insulation chambers also connect with side box body.
In actual applications, main box is arranged side by side with side box body, and maintenance door air intake assembly 12 is adopted with side air intake assembly
With two-stage wind scoop structure, when generating set is run, outside cold wind is from the first air inlet 1222 of maintenance door main body 122, and side
Second air inlet 1422 of air intake door main body 142 enters in casing, then passes through the first inlet scoop 126 and the second inlet scoop respectively
146 enter the first sound insulation chamber and the second sound insulation chambers, finally by the first sound insulation chamber and the second sound insulation chamber into main box and side
In casing.
In this way, during air intake, extend air intake path, extend buffer time so that air intake noise is in double-deck wind scoop
Between, cut down, reduce air intake noise.In addition, double-deck wind scoop configuration also acts the effect of double-deck sound insulation, generator unit production
Raw noise needs guiding through double-decker and can just given off, and create a further reduction noise, has greatly reinforced soundproof effect, improves
Running environment.
In one embodiment, the sound-insulation structure 10 also includes top air intake assembly 16, and the top air intake assembly 16 is set
At the top of main box, top air intake assembly 16 includes the jacking air door main body 162 provided with the 3rd air inlet 1622 and jacking air door master

Two door sockets 144 are arranged at the top of side box body, and the air inlet of side suction silencer 148 connects with the exhaust outlet of the second door socket 144, side
The exhaust outlet of suction silencer 148 connects with side box body.
Also referring to Fig. 2, further, side suction silencer 148 includes body 1482 and provided with air draft punching 1486
Acoustical panel 1484, body 1482 has a muffler chamber, and acoustical panel 1484 is arranged in muffler chamber, and cooperation is defined in fan
The silencers channel of palace formula.Specifically, acoustical panel 1484 includes acoustical panel main body and silencing cotton layer, and silencing cotton layer is covered in acoustical panel
In main body, then offer some air draft punchings.
In this way, further playing noise reduction, the effect of noise reduction, running environment is improved.
It is pointed out that the connection between side air intake door main body 142, the second door socket 144 and the three of the second inlet scoop 146
Relation and position relationship, with maintenance door main body 122, the annexation between the first door socket 124 and the three of the first inlet scoop 126 and
Position relationship is similar, and difference is that door main body, door socket, the size of wind scoop and model are different, for ease of description, therefore does not go to live in the household of one's in-laws on getting married herein
State the annexation between side air intake door main body 142, the second door socket 144, the concrete structure of the second inlet scoop 146 and three and position
Put relation.
It should be appreciated that in specific implementation, side air intake door main body 142, the second door socket 144 and the second inlet scoop 146
Size, annexation and position relationship between three can as the case may be depending on, be not limited thereto.For example, at one
In preferable embodiment, the bottom side of side air intake door main body 142 is provided with the second air inlet 1422, and the second inlet scoop 146 is set
