AI Technical Summary
Existing diesel generator set protective covers are usually quite sealed when pursuing sound absorption, which affects the heat dissipation of the equipment. Furthermore, the heat dissipation vents of traditional sound-absorbing materials can interfere with the sound absorption effect, making it difficult to achieve both sound absorption and heat dissipation.
The design employs a double-layer staggered sound-absorbing panel. Sound-absorbing side panels are installed by setting installation ports on the side wall of the protective cover. The staggered distribution of the sound-absorbing panels increases the noise reflection path, and heat dissipation holes are set between the sound-absorbing panels to achieve a balance between sound absorption and heat dissipation.
While improving the sound absorption effect, the staggered distribution of sound-absorbing panels increases the noise reflection path, takes into account the heat dissipation effect of the equipment, and the sound-absorbing side panels are easy to disassemble and replace.

Technical Field
[0001] This utility model belongs to the technical field of generator set protective covers, specifically relating to a double-layer staggered sound-absorbing panel generator set protective cover. Background Technology
[0002] A complete generator set generally consists of a diesel engine, generator, control box, fuel tank, starting and control batteries, protection devices, emergency cabinet and other components. Because diesel generators generate a lot of noise during operation, many diesel generator sets are usually equipped with protective covers on the outside for protection and sound absorption.
[0003] Currently, sound-absorbing panels are typically attached to the inner wall of the protective cover, or sound-absorbing materials are directly used to make the protective cover. Although this can absorb sound, it is usually quite sealed to ensure the sound absorption effect, which is not conducive to the heat dissipation of the main body of the equipment inside. However, opening heat dissipation vents on the protective cover will interfere with the sound absorption effect. Therefore, it is necessary to propose a double-layer staggered sound-absorbing panel generator set protective cover to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0022] Please see Figure 1-5This utility model provides the following technical solution: a protective cover for a double-layer staggered sound-absorbing panel generator set, including a main body 1, a protective cover 2 fixed on one side of the main body 1, the specific structure and operating principle of the main body 1 can refer to the generator sets in the prior art, the protective cover 2 has symmetrically provided mounting openings 22 on the side wall, and a sound-absorbing side plate 3 is fixed on the inner side of the mounting opening 22, the sound-absorbing side plate 3 includes an outer plate 31, a shielding cylinder 32, a mounting bracket 33, a first sound-absorbing plate 34 and a second sound-absorbing plate 35, which can be referred to in the appendix for details. Figure 3 Appendix Figure 4 and attached Figure 5 The outer panel 31 has heat dissipation holes 314 through its sidewall for auxiliary heat dissipation. The sidewall of the outer panel 31 also has a first slot 312 and a second slot 313, both of which are inclined. The first slot 312 is located on one side of the heat dissipation hole 314, and the second slot 313 is located on the other side. A first sound-absorbing plate 34 is inserted into the inner side of the first slot 312, and a second sound-absorbing plate 35 is inserted into the inner side of the second slot 313. The first and second sound-absorbing plates 34 and 35 are arranged in a staggered V-shape, with one end of the first sound-absorbing plate 34 located on one side of the middle of the second sound-absorbing plate 35. The heat dissipation holes 314 are located between the first and second sound-absorbing plates 34 and 35, respectively, without contact between the two plates. Multiple heat dissipation holes 314 are provided, as are multiple first and second sound-absorbing plates 34 and 35. A shielding cylinder 32 is fixed to the edge of the outer panel 31, passing through the mounting opening 22. A mounting bracket is fixedly connected to one side of the shielding cylinder 32. 33. The mounting bracket 33 is fixedly connected to the inner wall of the protective cover 2. The mounting bracket 33 includes a fixing plate 331, a fixing hole 332, a connecting cylinder 333, and a connecting frame plate 334. The fixing plate 331 is fixed to the inner wall of the protective cover 2. The fixing plate 331 is located outside the mounting opening 22. A connecting cylinder 333 is fixed to one side wall of the fixing plate 331. A connecting frame plate 334 is fixed to one side of the connecting cylinder 333. One end of the shielding cylinder 32 is fixedly connected to the connecting frame plate 334. In this solution, the sound-absorbing side plate 3, after installation, can absorb sound through two sets of staggered sound-absorbing plates. Due to the staggered distribution, the noise reflection path is increased, improving the sound absorption effect. At the same time, heat dissipation holes 314 are set between the two sets of sound-absorbing plates. While absorbing sound through the sound-absorbing plates, heat dissipation can be assisted through the gaps between the sound-absorbing plates and the heat dissipation holes 314. Compared with conventional closed sound-absorbing materials, the sound-absorbing side plate 3 takes into account both sound absorption and heat dissipation, and has strong functionality.
[0023] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the fixing plate 331 has a fixing hole 332 on its side, and a fixing bolt 21 passes through the outer wall of the protective cover 2. One end of the fixing bolt 21 passes through the fixing hole 332. The sound-absorbing side plate 3 can be fixed by the external bolt passing through the protective cover 2 and the fixing hole 332. The existing bolt fixing method can be used as a reference. Afterwards, the bolt can be removed so that the sound-absorbing side plate 3 can be detached and taken out from the inside of the mounting port 22. Then the mounting port 22 can be opened to check the internal equipment. Example 2
[0024] In another embodiment of this solution, refer to Figure 3 , Figure 4 and Figure 5 As shown, specifically, the upper ends of the first slot 312 and the second slot 313 pass through the shielding tube 32. One end of the shielding tube 32 is fixed with a telescopic tube 321. One end of the telescopic tube 321 is fixedly connected to the side wall of the connecting frame plate 334. The connecting tube 333 is located outside the telescopic tube 321 and the shielding tube 32. A handle 311 is fixed in the middle of one side wall of the outer plate 31. When the sound-absorbing panel needs to be replaced or repaired later, the operator can pull the outer plate 31 outward to stretch the telescopic tube 321 and move the shielding tube 32 to the outside of the installation port 22. The operator can then lift and pull out the sound-absorbing panel from the top of the shielding tube 32, which is convenient for disassembly and assembly.
[0025] Reference Figure 5 As shown, specifically, a compression washer 315 is fixed on the outer side of the outer plate 31. The compression washer 315 is made of elastic material. The outer ring size of the compression washer 315 is adapted to the inner ring size of the mounting opening 22. After the outer plate 31 is pushed to the inside of the mounting opening 22, the compression washer 315 can improve the engagement stability between the outer plate 31 and the mounting opening 22.
[0026] The working principle and usage process of this utility model are as follows: An installation opening 22 is provided on the protective cover 2 of the generator set. The sound-absorbing side plate 3 is placed horizontally and inserted into the inner side of the protective cover 2 through the installation opening 22. Then, the mounting bracket 33 of the sound-absorbing side plate 3 is placed against the inner wall of the protective cover 2 and fixed with bolts, allowing the shielding cylinder 32 and outer plate 31 of the sound-absorbing side plate 3 to pass through the installation opening 22. The operator then pulls the outer plate 31 outwards, causing the shielding cylinder 32 to extend. Subsequently, the operator inserts multiple first sound-absorbing plates 34 into the inner side of the first slot 312 from the top of the shielding cylinder 32, and inserts second sound-absorbing plates 35 into the inner side of the second slot 313, resulting in a staggered distribution of the two sets of sound-absorbing plates. Simultaneously, the sound-absorbing plates are located on both sides of the heat dissipation holes 314 on the outer plate 31. This staggered distribution of sound-absorbing plates increases the noise reflection path, thereby improving the sound absorption effect, while also allowing for heat dissipation through the heat dissipation holes 314, demonstrating strong functionality.
