[0040] An air inlet 7 is provided on the box body corresponding to the unit cavity 4. There are two groups of air inlets 7, which are arranged opposite to each other. An air guide structure 8 is provided at the position corresponding to the air inlet in the unit cavity 4.
[0041] An air outlet plate 9 is provided at the top of the unit cavity 4, one end of the air outlet plate 9 is connected to the side wall of the unit cavity 4, and the other end of the air outlet plate 9 is an air outlet free end 901. A gap is left between the air outlet free end 901 and the partition 2 to form an air outlet port 10, and a gap is left between the air outlet plate 9 and the top of the unit cavity 4 to form an air outlet channel 11. The air outlet 10 is connected to the air outlet channel 11; a muffler 12 is provided in the air outlet channel 11.
[0042] The gas required for the operation of the generator set enters the unit cavity from the air inlet through the air guide structure, avoiding the gas from directly entering the unit cavity. The setting of the air guide structure is conducive to reducing the speed of the gas entering the unit cavity, thereby reducing the noise of the gas entering the unit cavity; and the hot air generated when the generator set is running is discharged through the air outlet and the air outlet channel. In the process of the hot air being discharged through the air outlet channel, the hot air passes through the muffler to reduce the noise of the gas discharge, thereby reducing the overall noise of the generator set.
[0043] As a preferred embodiment, the air guide structure 8 in the present application includes a wind shield 801 and an L-shaped guide plate. The wind shield 801 is arranged at the air inlet 7, and a distance is left between the wind shield 801 and the air inlet 7. A first section of the channel 804 is formed between the wind shield 801 and the four walls of the unit cavity; the L-shaped guide plate is arranged at the top of the wind shield 801;
[0044] The L-shaped guide plate includes a horizontal plate 802 and a vertical plate 803, one end of the horizontal plate 802 is horizontally arranged on the inner wall of the unit cavity 4, and one end of the vertical plate 803 is vertically provided on the other end of the horizontal plate 802, and the other end of the vertical plate 803 extends toward the bottom end of the unit cavity 4. A gap is left between the horizontal plate 802 and the top of the wind shield 801 to form a second section of the channel 805, and the vertical plate 803 and the wind shield 801 are both vertically arranged, and a gap is left between the vertical plate 803 and the wind shield 801 to form a third section of the channel 806, and the first section of the channel 804 is connected to the second section of the channel 805 and the third section of the channel 806 in sequence to form an air guide channel.
[0045] The air guide channel in the present application is in a bent shape, so that the gas entering the unit cavity cannot enter in a straight line. The gas must flow along the path of the air guide channel. The setting of the wind shield, horizontal plate and vertical plate in the air guide structure blocks and restricts the air entering the unit cavity from the air inlet, so that the gas path is extended and the gas flow rate is effectively reduced, which is beneficial to reducing the noise of the gas entering the unit cavity.
[0046] The horizontal plate and the vertical plate in this application are integrally formed, the center of the horizontal plate is located directly above the wind shield, and one end of the vertical plate extending to the bottom end of the unit cavity is lower than the top end of the wind shield, so as to extend the length of the third section of the channel and effectively reduce the flow rate of the gas.
[0047] The air inlet in the present application is provided with an air inlet box 13, the air inlet box 13 includes a frame 1301, and multiple groups of air inlet structures are arranged in sequence from top to bottom on the frame 1301, with a distance between two adjacent air inlet structures;
[0048] The air inlet structure includes a first air inlet guide plate 1302 and a second air inlet guide plate 1303. The first air inlet guide plate 1302 and the second air inlet guide plate 1303 are arranged on opposite sides of the frame 1301.

One end of the second air inlet guide plate 1303 is a second connecting end and the other end is a second free end 13031.
[0049] The first air inlet guide plate 1302 is tiltedly arranged on one side of the frame, and the first connection end of the first air inlet guide plate is higher than the first free end 13021, and the first connection end is arranged in the frame; the second air inlet guide plate 1303 is tiltedly arranged on the other side of the frame, the second connection end is higher than the second free end 13031, and the second connection end is connected to the first connection end; an inverted V-shaped air inlet channel is formed between the first air inlet guide plate and the second air inlet guide plate, so that the gas cannot flow in a straight line, which increases the gas flow path while also achieving gas blocking, which is beneficial to reducing the gas flow rate and reducing the noise of the gas passing through the air inlet box.
[0050] As a preferred embodiment, the first air inlet guide plate 1302 and the second air inlet guide plate 1303 in the present application are symmetrically arranged along the connection between the first connection end and the second connection end; the structure is simple and the manufacturing is convenient;
[0051] The first air inlet guide plate 1302 and the second air inlet guide plate 1303 both include a steel plate 13a, a perforated plate 13b and sound-absorbing cotton 13c. Perforated plates 13b are symmetrically arranged on both sides of the steel plate 13a, and sound-absorbing cotton 13c is arranged between the steel plate 13a and the perforated plate 13b. The steel plate supports the perforated plate and the sound-absorbing cotton. The setting of the perforated plate and the sound-absorbing cotton utilizes the propagation of sound waves in the porous material to convert the sound energy into heat energy due to friction and dissipate it, thereby achieving the purpose of noise reduction.
[0052] The muffler 12 in the present application includes a muffler housing 14 and a front muffler structure 15 and a rear muffler structure 17 disposed within the muffler housing. The front muffler structure 15 is located at the muffler housing air inlet 1401, and the rear muffler structure 17 is located at the muffler housing air outlet 1402. A distance is provided between the front muffler structure 15 and the rear muffler structure 17. By providing the front muffler structure and the rear muffler structure, exhaust gas noise is reduced, achieving silent operation of the generator set.
[0053] The front muffler structure 15 in the present application includes a front baffle 1501, a front top arc plate 1502 and a front bottom arc plate 1503. The front baffle 1501 is vertically arranged in the muffler box and is arranged corresponding to the muffler air inlet 1401. A distance is left between the front baffle 1501 and the muffler air inlet 1401. The front top arc plate 1502 is arranged at the top of the front baffle 1501 and the front top arc plate 1502 is connected to the top of the muffler box 14. The front bottom arc plate 1502 is arranged at the bottom end of the front baffle 1501 and the front bottom arc plate 1503 is connected to the bottom end of the muffler box.

There is a distance between the rear baffle 1701 and the sound-absorbing air outlet 1401. The rear top arc plate 1702 is arranged at the top of the rear baffle 1701, and the rear top arc plate 1702 is connected to the top end of the sound-absorbing box 14. The rear bottom arc plate 1703 is arranged at the bottom end of the rear baffle 1701, and the rear bottom arc plate 1703 is connected to the bottom end of the sound-absorbing box 14. The rear top arc plate and the rear bottom arc plate are both perforated plates.
[0055] The hot gas generated during the operation of the generator set first enters the outlet channel through the outlet. When the hot air enters the muffler box, it enters the front muffler structure through the muffler box air inlet. Specifically, the hot gas enters the front muffler structure and collides with the front baffle. The gas is diverted to the front top arc plate and the front bottom arc plate to flow into the muffler box. The setting of the front baffle reduces the flow rate of the hot air entering the muffler box, which is conducive to achieving uniform diversion of the hot air, extending the flow path of the hot air, and reducing the noise during the hot air circulation. When the hot air flows through the rear muffler structure, the setting of the rear baffle also greatly reduces the flow rate of the hot gas, extends the flow path of the hot gas, reduces the exhaust speed of the hot gas, and reduces the sound of the hot gas exhaust. When the hot gas flows through the front top arc plate, the front bottom arc plate, the rear top arc plate, and the rear bottom arc plate, the sound energy is converted into heat energy due to friction when the sound waves propagate in the porous material and dissipated, so that the noise propagating along the pipeline is attenuated with distance, thereby achieving the purpose of sound elimination.
[0056] As a preferred embodiment, the present application further includes a middle noise reduction structure 16, which is located between the front noise reduction structure 15 and the rear noise reduction structure 17, and there is a gap between the middle noise reduction structure and the front noise reduction structure, and between the middle noise reduction structure and the rear noise reduction structure; the middle noise reduction structure includes a middle air inlet box and a middle air outlet box, and there is a gap between the middle air inlet box and the middle air outlet box;

[0060] The setting of multiple air inlet baffles and multiple air outlet baffles in this application prevents the hot gas entering the middle sound-absorbing structure from flowing in a straight line, and can only flow along the path of the middle sound-absorbing structure, thereby extending the flow path of the hot gas. The setting of multiple air inlet baffles and air outlet baffles is conducive to reducing the flow rate of the hot gas, and combined with the sound-absorbing cotton, it greatly reduces the noise of the hot gas exhaust.
[0061] As a preferred embodiment, the outer wall of the silencer box in the present application is provided with a shell 1403, and a cavity is formed between the shell 1403 and the outer wall of the silencer box.

Due to the arrangement of the front silencer structure 15, the middle silencer structure 16 and the rear silencer structure 17 in the silencer box, the path of the exhaust gas is extended, the contact area between the exhaust gas and the cooling water is increased, and the exhaust gas is cooled, which is beneficial to reduce the temperature of the hot air in the unit cavity and realize the stable operation of the generator set.

The air outlet fan 18 is arranged on a mounting frame 1801, and the mounting frame 1801 is arranged on a partition 2, and an angle of 45° is formed between the mounting frame 1801 and the partition 2; the setting of the air outlet fan 18 is conducive to increasing the speed of gas discharge from the air outlet channel, reducing the residence time of hot air in the unit cavity, increasing the gas convection speed in the unit cavity, and helping to reduce the temperature in the unit cavity, thereby realizing stable operation of the generator set.
[0063] The generator set 6 is arranged on a base 19, and an elastic device is provided between the base 19 and the bottom end of the unit cavity. There are two groups of elastic devices, which are respectively arranged at the bottom end of the base.
