[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0031] Please refer to Figures 1 to 8 The embodiment of the present invention provides an exhaust component and a generator noise reduction structure, including a square steel pipe 1 and an iron sheet 2. The square steel pipe 1 is provided with a plurality of boxes assembled into a frame, and the iron sheet 2 is installed on the outside of the box frame. After the box frame and the iron sheet 2 are assembled, a cabin for wrapping the generator is formed. The exhaust pipe of the generator is connected to the muffler 16. The connection between the exhaust pipe and the muffler 16 adopts a high-performance sealing material to ensure that there is no leakage during the exhaust process, thereby reducing the propagation path of the noise. The interior of the muffler 16 is filled with high-efficiency sound-absorbing materials. These materials can effectively absorb and convert exhaust noise into heat energy, significantly reducing the exhaust noise level. One end of the muffler 16 is connected to one end of the pipe 15, and the other end of the pipe 15 extends out of the through hole 13 opened on the back of the cabin.

[0032] A plurality of through holes 7 are opened at the lower end of the right side of the engine compartment. The width of the through holes 7 is 4CM and the height is 14CM. The interval between each through hole 7 is 4CM. The through holes 7 can significantly increase the contact area between the engine compartment and the external environment, thereby improving the heat dissipation efficiency. Although the through holes 7 are not directly involved in the exhaust process, they can indirectly affect the overall efficiency of the exhaust system. By optimizing the air flow inside the engine compartment, the resistance of the exhaust system inside the engine compartment can be reduced, so that the exhaust gas can be discharged more smoothly.

[0033] On the other hand, the present application also provides an exhaust component and a generator noise reduction structure, including: a partition 8, the partition 8 is installed inside the engine room constructed by a square steel pipe 1 and an iron sheet 2, and a soundproofing chamber 9 is formed between the partition 8 and the inner wall of one side of the engine room. The soundproofing chamber 9 isolates and absorbs the noise generated by the generator. When the noise sound waves propagate to the soundproofing chamber 9, the sound-absorbing material in the room can effectively convert the sound waves into heat energy, thereby significantly reducing the propagation of noise.

[0034] A temperature control device 11 is installed at the upper end of the anechoic chamber 9. At the same time, a slot 12 is opened at the upper end of the partition 8. A 60W exhaust fan 10 is installed in the slot 12. The high temperature inside is extracted by the exhaust fan 10. The temperature control device 11 can intuitively display the internal temperature. The exhaust fan 10 is used to increase the ventilation volume to achieve rapid cooling when the temperature is too high in hot weather.

[0035] An air outlet 14 is provided at the bottom of the left side of the engine compartment. The air outlet 14 also helps to promote the air circulation inside the engine compartment. When external air enters the engine compartment through other openings of the engine compartment, such as the through hole 7 and the silencer chamber 9, the air outlet 14 can be used as an exhaust port to discharge the air inside the engine compartment, thereby forming a complete air flow cycle. This cycle helps to reduce the temperature and humidity inside the engine compartment and improve the operating efficiency of the generator.

[0036] A pair of front door panels 5 are provided on the front side of the machine cabin, and a single rear door panel 6 is provided on the rear side of the machine cabin, so that the front door panels 5 and the rear door panels 6 can be used to operate the machine unit and related equipment.

[0037] Furthermore, fireproof cotton 3 is provided on the inner side of the iron sheet 2, and wire mesh 4 is provided on the outer side of the fireproof cotton 3. The fireproof cotton 3 is a 10 cm thickened industrial fireproof special noise reduction material, which greatly suppresses mechanical noise. In addition, a bracket 17 is installed at the upper end of the machine room, and the bracket 17 can be used to install other required equipment.

[0038] In summary, the exhaust assembly and generator noise reduction structure of the embodiment of the present invention have the following working principles: a square steel pipe 1 and an iron sheet 2 are welded together to form a cabin that wraps the generator, and a front door panel 5 and a rear door panel 6 are opened on both sides of the cabin to facilitate the operation of the unit and related equipment through the door. The interior of the cabin is designed to be thickened with industrial fire-proof special noise-reducing fireproof cotton 3 for noise reduction, and a partition 8 is used to separate the silencer room 9 to reduce noise. At the same time, the exhaust fan 10 can extract the heat inside the cabin to reduce the internal temperature, and the internal temperature is displayed by the temperature control device 11.

[0039] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
