As shown in fig. 1 to 5, according to an embodiment of the present invention, there is provided a wind inlet device for a generator set, including:

a silent sound box door body 10; an air inlet hole 11 is arranged on at least part of the surface of the silent sound box door body 10;

the main body part 20, the main body part 20 is arranged on the inner side of the silent sound box door body 10; and

the partition plate 30 is disposed inside the main body 20, and the first sound absorbing layer 31 and the second sound absorbing layer 32 are disposed on both sides of the partition plate 30.

This use is novel through setting up baffle 30 in the inside of main part 20, separates into circuitous wind channel with the wind channel of main part 20 to set up first sound absorbing layer 31 and second sound absorbing layer 32 respectively in the both sides of baffle 30, for generating set hot blast blowpipe apparatus among the prior art, increased the number of piles on sound absorbing layer, increased the effect of making an uproar, realize multiple syllable-dividing and fall the noise.

The air intake device of the generator set further comprises a back plate 40 and a third sound absorption layer 41, wherein the third sound absorption layer 41 is arranged on one side of the back plate 40 far away from the main body part 20. Through set up third sound absorbing layer 41 in the one side that main part 20 was kept away from to backplate 40, the noise can further be reduced, and can not increase generating set's size, simple structure, convenient production.

In addition, because the back plate 40 and the partition plate 30 are both arranged on the inner side of the silent sound box door body 10, the internal space of the generator set silent sound box is effectively utilized, and the volume of the external space occupied by the generator set silent sound box 100 cannot be increased.

The first sound-absorbing layer 31, the second sound-absorbing layer 32 and the third sound-absorbing layer 41 may be made of sound-absorbing materials, such as sound-absorbing cotton. The partition plate 30 and the first sound absorbing layer 31 and the second sound absorbing layer 32 on the two sides can be manufactured by adopting an integral forming process, so that the subsequent installation is convenient. The partition board 30 and the main body portion 20 and/or the back board 40 and the main body portion 20 are mechanically connected, for example, by using a bolt structure or a self-tapping screw, and may also be fixed by using an adhesion process or a welding process.

The number of the spacers 30 is one, and is provided at an intermediate position in the thickness direction of the main body 20. The air enters the wind inlet device of the generator set from the air inlet holes 11 of the mute box door 10, flows along the air channel between the main body part 20 and the right side of the partition plate 30, flows upwards firstly, then flows horizontally, then flows downwards in the air channel between the main body part 20 and the left side of the partition plate 30, then enters the interior of the generator set, and reduces noise under the action of the partition plate 30, the first sound absorption layer 31, the second sound absorption layer 32, the back plate 40 and the third sound absorption layer 41.

The number of the partition plates 30 is plural, and the plural partition plates 30 are provided at intervals inside the main body portion 20. Wherein the plurality of partition plates 30 are arranged in parallel with each other. By providing a greater number of the partition plates 30, the sound insulation effect can be increased, and the noise can be reduced. In addition, since the first and second

sound absorbing layers

31 and 32 are disposed on both sides of each partition plate 30, the sound absorbing effect can be increased and noise can be reduced.

The bottom of the main body 20 has a bevel plate 21. By arranging the inclined plane plate 21, the rainproof window can effectively prevent rain, conveniently discharge the entering water and is beneficial to water drainage.

The inclined plate 21 is inclined downward in the direction of the silent box door 10. By setting the inclined plane plate 21 to be inclined downward from the bottom of the partition 30 toward the edge of the main body portion 20, the moisture can be collected at the lower end of the inclined plane plate 21, and can be discharged from the air inlet hole 11 of the silent box door 10, which is advantageous for drainage.

The outer edge of the contact surface of the partition board 30 with the main body 20 is provided with a sealing strip 50. Through setting up sealing strip 50, can prevent that the rainwater from getting into generating set silence case, to the gap department that can't use sealing strip 50, can adopt the fixed glue to fill, prevent into water. The sealing strip 50 is also required to be disposed at the edge portion of the contact surface between the main body portion 20 and the mute door body 10 to prevent rainwater from entering, and for the position where the sealing strip 50 is inconvenient to use, the sealing strip is filled with fixing glue to prevent water from entering.

For ease of installation, the height of the baffle 30 is slightly less than the height of the main body portion 20, such that the baffle 30 is located inside the main body portion 20. The height of the back plate 40 is equal to or slightly lower than that of the main body part 20, and the third sound-absorbing layer 41 can be fixed on the inner side of the back plate 40 by bonding or other connection means between the back plate 40 and the third sound-absorbing layer 41.

The body portion 20 is rectangular or stepped in cross-section. The main body 20 is rectangular for easy processing, and the back plate 40 is a unitary plate. The main body 20 may be provided in a stepped shape, and in this case, the back plate 40 is two or more plates respectively provided on the inner side of the main body 20, so that the inner space of the power plant soundbox 100 can be fully utilized.

According to an embodiment of the present invention, there is also provided a generator set sound box 100, including the aforementioned generator set air intake devices, which are disposed on the side surfaces of the generator set sound box 100, and in fig. 5, the number of the generator set air intake devices is three, and the three generator set air intake devices are respectively located on two side surfaces and the front end surface of the generator set.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
