[0002] In the industrial and commercial fields, engines are widely used as power sources in various equipment, such as engines, compressors and pumps. However, the noise generated by the engine during operation often has a significant impact on the surrounding environment, especially in densely populated areas or areas with strict noise restrictions. In order to solve this problem, silent boxes came into being, aiming to reduce the spread of engine noise through sound insulation materials and technologies. In order to ensure good sound insulation, the existing silent boxes are often designed to be relatively closed, which means that once the engine or related components fail, maintenance personnel need to spend a lot of time and effort to open the box for inspection. The door and cover design of traditional silent boxes is often not user-friendly, inconvenient to open, and the space is narrow, which brings inconvenience to maintenance work and increases downtime and maintenance costs.

[0003] The existing mute box is a single-layer structure. The single-layer mute box design limits the combination of the engine unit and different equipment in certain scenarios, thereby limiting the versatility and flexibility of the system. The single-plane layout is difficult to accommodate more equipment or modules, limiting the expansion and upgrade of system functions. It is not easy to combine the engine unit with special-purpose equipment (such as pumps, compressors, lighting systems, etc.) to form a customized solution.

[0004] In order to solve the above technical problems, the utility model designs a double-layer sound-proof box. Utility Model Content

[0031] The upper box body 13 is provided with an upper support rib 131. Each module on the upper box body 13 also has a corresponding inspection door, so that the corresponding module can be inspected without disassembling and installing a mute box.

[0032] The second air inlet 292 is a louvered opening. The louvered opening is designed with a special angle and shape to guide rainwater to flow downward instead of entering the lower box 22. The inclination angle and direction of the blades make it difficult for rainwater to penetrate directly while allowing air to circulate.

[0033] The lower box base 21 is provided with a lower reinforcement rib 211. The upper box base 12 is provided with an upper reinforcement rib 121

[0034] The outlet door plate 26 is connected to the outlet box 261, and the outlet box 261 has an inlet 262. The engine wire harness is received in the outlet box 261 through the inlet 262 and passes through the gap between the outlet door plate 26 and the lower box body 22.

[0036] Place the working equipment on the upper layer of the double-layer silent box and the engine on the lower layer. The engine usually produces a higher noise level. Placing it on the lower layer of the silent box can effectively use the sound insulation material of the box to reduce the spread of noise, especially the impact on the working equipment on the upper layer.

[0037] The layered design allows for more efficient space management, the upper layer can be designed to be more spacious for easier operation and monitoring, while the lower layer can compactly house the engine and its related accessories, making it more convenient to use with the mobile trolley 3.

[0038] By placing the engine group on the lower level and different equipment on the upper level, the equipment on the upper level can be easily replaced or added according to specific application requirements without affecting the engine group on the bottom level. This design makes the engine group the basic platform, and systems with different functions can be quickly configured according to the specific needs of customers, such as mobile power stations, emergency rescue systems, construction site support systems, etc. The two-layer setting makes it easier to integrate various equipment, and through standardized interfaces and modular design, plug-and-play equipment is realized, simplifying the system construction and maintenance process.

[0039] This integration capability allows users to expand the system's application areas without changing the core power generation function, such as agricultural irrigation, power supply for construction sites, outdoor activity support, etc.

[0040] After placing the engine on the lower box base 21, install the lower box body 22, which can be fixed with bolts, etc., so that the engine controller corresponds to the controller door panel 24, the emergency stop button corresponds to the emergency stop button box 25, the engine wiring harness is stored in the outlet box 261, and passes through the gap between the outlet door panel 26 and the lower box body 22, and the engine exhaust interface is installed on the smoke inlet 272 of the exhaust pipe 27, and the exhaust pipe 272 leads to the lower box base 21 and the mobile car 3, and is discharged through the smoke outlet 273.

[0041] The gas enters from the first air inlet 291 and the second air inlet 292 and is exhausted and dissipated through the heat dissipation port 28 .

[0042] While ensuring the soundproof box is closed, the baffle 293 and the shutter opening can effectively prevent rain, and the sound-absorbing cotton arranged in the soundproof box can achieve the effect of isolating sound.

[0043] The modular setting of multiple inspection doors in the silent box means that the engine or working equipment can be approached from different directions, simplifying the maintenance and inspection process. This is especially beneficial for large or complex equipment, because all operations do not need to be performed from a single entrance, which can improve work efficiency. The fast and convenient modular setting design can reduce equipment downtime, because it can enter and exit faster during maintenance, which helps to shorten the non-operating state of the equipment and improve production efficiency.

[0044] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
