Detailed Embodiments

[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] First Embodiment:

[0024] Please refer to Figures 1 to 3 , where Figure 1 is the front view of the first embodiment of the present invention, Figure 2 is a Figure 1 cross-sectional view taken along line A-A in the present invention, Figure 3 is a Figure 2 cross-sectional view taken along line B-B in the present invention.

[0025] The present invention provides a silent sound insulation system for a generator set, which includes an air outlet hood 101, an air inlet hood 102 and a silent box 103. A plurality of air outlet pipes 104 are connected to the front end face of the air outlet hood 101. A plurality of air inlet pipes 105 are connected to the rear end face of the air inlet hood 102. Silencers 106 are provided on both the air outlet pipes 104 and the air inlet pipes 105. One end of the silent box 103 has an air outlet 107, and the other end of the silent box 103 has an air inlet 108. A generator set mounting plate 109 is provided in the middle of the silent box 103. Two adjusting screws 110 are rotatably provided between the air inlet 108 and the generator set mounting plate 109. One of the adjusting screws 110 is driven by a stepper motor 111. The two adjusting screws 110 are driven by a synchronous belt 112 and a synchronous pulley 113. An installation frame 114 is threadedly provided between the two adjusting screws 110. A plurality of heat dissipation fans 115 are provided in the installation frame 114, and the air outlet ends of the plurality of heat dissipation fans 115 are arranged towards the direction of the generator set mounting plate 109. The air outlet hood 101 is fixedly connected to the silent box 103 and is located at one end of the silent box 103. The air inlet hood 102 is fixedly connected to the silent box 103 and is located at the other end of the silent box 103. By integrating the air outlet hood 101, the air inlet hood 102 and the silent box 103, efficient sound insulation and heat dissipation functions are achieved. The silencers 106 provided on the air outlet hood 101 and the air inlet hood 102 effectively reduce the air flow noise and ensure air circulation at the same time. The generator set mounting plate 109 designed inside the silent box 103 facilitates the stable installation of the generator set. Then, through the adjusting screws 110 driven by the stepper motor 111 and the synchronous belt 112 and the synchronous pulley 113 drive system, the position of the heat dissipation fans 115 in the installation frame 114 can be flexibly adjusted to ensure that the generator set is evenly and effectively cooled, thereby improving the operating stability and service life of the generator set.

[0026] Wherein, the rear end face of the air outlet hood 101 has a conical surface 116, and a plurality of the air outlet pipes 104 are located at the bottom end of the conical surface 116. The design of the conical surface 116 also helps to reduce eddy currents and noise, improves the overall sound insulation effect, and at the same time makes the discharged air flow smoother, reduces the air flow resistance, and further improves the heat dissipation efficiency.

[0027] Secondly, a placement opening 117 is provided above the silent box 103, and a silent top plate 118 is embedded at the placement opening 117. Through the silent top plate 118, the sealing performance inside the silent box 103 can be ensured to prevent noise leakage. At the same time, the design of the placement opening 117 enables the staff to easily repair and install the generator set.

[0028] When using a silent sound insulation system for a generator set according to this embodiment, first, firmly install the generator set on the generator set mounting plate 109 in the middle of the silent sound box 103. Then, start the stepping motor 111. Through the transmission of the synchronous belt 112 and the synchronous pulley 113, adjust the positions of the two adjusting screws 110, so as to adjust the lateral movement position of the heat dissipation fan 115 in the mounting frame 114. And the mounting frame 114 realizes reciprocating motion under the forward and reverse rotation of the stepping motor 111, ensuring that the air outlet end of the heat dissipation fan 115 faces the generator set to achieve efficient heat dissipation. When the generator set is running, cold air enters from the air inlet pipe 105 of the air inlet cover 102, passes through the muffler 106 to reduce noise, and then is blown towards the generator set by the heat dissipation fan 115 to take away heat, and then is discharged from the air outlet pipe 104 of the air outlet cover 101, also passing through the muffler 106 to reduce noise. In this way, it effectively solves the technical problems that in actual use, due to the relatively sealed overall structure, the temperature of each area inside is relatively high, and its heat dissipation effect is limited, unable to effectively dissipate heat in multiple areas, and thus easily causes damage to the generator set and a decrease in its service life.

[0029] Second Embodiment:

[0030] On the basis of the first embodiment, please refer to Figures 4 to 5 , where Figure 4 is a side view of the second embodiment of the present invention, Figure 5 is the Figure 4 cross-sectional view taken along line C-C in

[0031] The present invention provides a silent sound insulation system for a generator set, which further includes two generator set fixing mechanisms and a support mechanism 201. The two generator fixing mechanisms are symmetrically arranged on the generator set mounting plate 109 respectively, and the support mechanism 201 is arranged below the silent sound box 103. Through the generator set fixing mechanism, it is ensured that the generator set is firmly fixed on the generator set mounting plate 109, preventing noise and damage caused by vibration. The support mechanism 201 provides a stable supporting force to ensure the stability of the entire silent sound insulation system.

[0032] Among them, the generator set fixing mechanism includes a fixing screw 202, a fixing plate 203 and a threaded sleeve 204. A slider is provided below the fixing plate 203. The upper end surface of the generator set mounting plate 109 has a plurality of chutes. The fixing screw 202 is rotatably connected to the fixing plate 203 through a bearing and is located at the rear end surface of the fixing plate 203. The fixing screw 202 is also threadedly connected to the threaded sleeve 204 and is located inside the threaded sleeve 204. The fixing plate 203 is slidably connected to the generator set mounting plate 109 through the slider and is located on the generator set mounting plate 109, and the slider is located in the corresponding chute. The threaded sleeve 204 is fixedly connected to the generator set mounting plate 109 and is located on the generator set mounting plate 109. The sliding connection is realized through the cooperation of the slider and the chute. This design enables the fixing plate 203 to be flexibly adjusted in position on the generator set mounting plate 109, facilitating adaptation to generator sets of different sizes and models. At the same time, the threaded connection between the fixing screw 202 and the threaded sleeve 204 provides a reliable fixing force to ensure that the generator set does not displace during operation.

[0033] Secondly, the generator set fixing mechanism further includes a buffer pad 205 and two limit members. The limit members include a limit rod 206 and a limit sleeve 207. The buffer pad 205 is adhesively connected to the fixing plate 203 and is located on the front end surface of the fixing plate 203. The limit rod 206 is fixedly connected to the fixing plate 203 and is located at the rear end surface of the fixing plate 203 and is also located on one side of the fixing screw 202. The limit rod 206 is also slidably connected to the limit sleeve 207 and is located inside the limit sleeve 207. The limit sleeve 207 is fixedly connected to the generator set mounting plate 109 and is located on the generator set mounting plate 109 and is also located on one side of the threaded sleeve 204. The buffer pad 205 can reduce the vibration and noise generated by the generator set during operation and protect the generator set from damage. The limit members limit the movement range of the conveying fixing plate 203 to prevent accidents caused by excessive vibration or external impact.

[0034] At the same time, the air outlet hood 101, the air inlet hood 102, the silent top plate 118 and the silent box 103 are all composed of an outer protective layer 210, two intermediate sound insulation layers 211 and a sound filtering layer 208, and an inner sound reduction layer 209. Through this multi-layer structure design, an efficient sound insulation effect is achieved. The sound insulation layer 211 and the sound filtering layer 208 can effectively isolate external noise, and the sound reduction layer 209 further reduces the reflection and propagation of internal noise. This design enables the entire silent sound insulation system to have excellent sound insulation performance and provides a quiet and stable working environment for the generator set.

[0035] Third embodiment:

[0036] Based on the second embodiment, please refer to Figure 6 ,in Figure 6 It is a three-dimensional stereogram of the third embodiment of the present invention.

[0037] The present invention provides a silent sound insulation system for a generator set, which also includes two top plate fixing mechanisms, wherein the top plate fixing mechanisms include a push screw 301, a push plate 302 and a C-shaped frame 303, wherein the C-shaped frame 303 has a threaded groove 304, wherein the push screw 301 is rotatably connected to the push plate 302 through a bearing and is located above the push screw, wherein the push screw 301 is also threadedly connected to the C-shaped frame 303 and is located in the threaded groove 304, wherein the push plate 302 is in conflict with the silent top plate 118 and is located on the upper end surface of the silent top plate 118, The C-shaped frame 303 is fixedly connected to the soundproof box 103 and is located above the soundproof box 103. Through the threaded connection between the push screw 301 and the C-shaped frame 303, and the mutual interference between the push plate 302 and the soundproof top plate 118, the soundproof top plate 118 can be stably fixed. This fixing method is not only simple in structure but also easy to adjust. The screw-in depth of the push screw 301 can be adjusted according to actual needs, thereby changing the pressure of the push plate 302 on the soundproof top plate 118 to ensure that the soundproof top plate 118 is stable and does not shake.

[0038] Among them, the top plate fixing mechanism also includes two positioning rods 305, and the C-shaped frame 303 also has two positioning grooves 306, and the threaded groove 304 is located between the two positioning grooves 306. The two positioning rods 305 are respectively fixedly connected to the push plate 302 and are located at both ends of the push plate 302. The two positioning rods 305 are also respectively slidably connected to the C-shaped frame 303 and are located in the corresponding positioning grooves 306. The design of the positioning rods 305 can prevent the push plate 302 from shifting or tilting when subjected to force, thereby ensuring that the silent top plate 118 can always remain in a horizontal state, thereby improving the stability of the entire silent sound insulation system.

[0039] Secondly, the supporting mechanism 201 includes a supporting frame 307 and a plurality of supporting legs 308. The supporting frame 307 is fixedly connected to the corresponding supporting legs 308 and is located below the plurality of supporting legs 308.
