[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a diesel engine muffler with a dustproof and waterproof protection structure, including a muffler body 1, an air outlet pipe 2 is fixedly connected to the upper surface of the muffler body 1, and a plurality of air outlet holes 3 are penetrated through the upper side of the inner part of the air outlet pipe 2, a mounting plate 4 is slidably connected to the outer wall of the air outlet pipe 2, an air outlet pipe 5 is fixedly connected to the upper surface of the mounting plate 4, and a plurality of air outlet holes 6 are penetrated through the lower side of the inner part of the air outlet pipe 25, a main shell 7 is fixedly connected to the upper surface of the mounting plate 4, a sliding ring 8 is slidably connected to the inner wall of the main shell 7, a limiting frame 9 is fixedly connected to the upper surface of the sliding ring 8, a spring 10 is sleeved on the outer wall of the limiting frame 9, and the spring 10 is sleeved on the outer wall of the spring 10. 0, one end of the spring 10 is fixedly connected to the upper surface of the sliding ring 8, the other end of the spring 10 is fixedly connected to the top of the inner wall of the main housing 7, the limit frame 9 is slidably connected to the inside of the main housing 7, one side of the lower surface of the limit frame 9 is fixedly connected to the connecting rod 11, and the lower surface of the connecting rod 11 is provided with a cleaning component 12; the cleaning component 12 includes a fixed ring 1201, the upper surface of the fixed ring 1201 is fixedly connected to the lower surface of the connecting rod 11, one side of the inner wall of the fixed ring 1201 is fixedly connected to a cleaning brush 1202, and the cleaning brush 1202 is slidably connected to the outer wall of the main housing 7; the upper surface of the limit frame 9 is fixedly connected to the support rod 13, and the upper surface of the support rod 13 is fixedly connected to a rainproof top 14;
[0023] Specifically, after the gas is purified, the gas will enter the outlet pipe 25 from the outlet hole 13, and then further enter the interior of the main shell 7. In this process, the gas not only realizes the internal flow, but also plays the role of pushing the sliding ring 8, so that it can slide smoothly inside the main shell 7. The movement of the sliding ring 8 is not isolated, it also drives the limit frame 9 to slide synchronously. The purpose of this design is to enable the gas cleaning brush 1202 to effectively clean the outer wall outlet of the main shell 7 through the fixing ring 1201 on the lower surface of the connecting rod 11. This series of actions realizes the cleaning of the gas flow path and ensures the efficient operation of the equipment. After completing the cleaning task, the spring 10 plays a role of rapid reset, so that the cleaning brush 1202 returns to the initial position and prepares for the next cleaning. In addition, the setting of the rainproof top 14 further improves the protective performance of the equipment and effectively prevents water from affecting the effect of the muffler body 1.
[0024] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the mounting plate 4 is fixedly connected with a left-right symmetrical connecting block 15, and the upper surface of the muffler body 1 is fixedly connected with a left-right symmetrical mounting column 16; the inner wall of the mounting column 16 is slidably connected with a left-right symmetrical sliding block 18, and one side of the outer wall of the sliding block 18 is fixedly connected with a clamping block 19; a telescopic rod 17 is fixedly connected between the sliding blocks 18, and a spring 20 is sleeved on the outer wall of the telescopic rod 17;
[0025] Specifically, the mounting plate 4 is mounted on the outer wall of the mounting column 16. At this time, the reaction force of the spring 20 is used to drive the sliding block 18 to move. In this step, the role of the spring 20 is crucial. When the spring 20 is compressed by an external force, a reaction force is generated. This reaction force can drive the sliding block 18 to slide on the mounting column 16, thereby achieving rapid movement. This design makes the installation process easier and reduces the difficulty of operation. Then, through the movement of the sliding block 18, the card block 19 is pushed to engage with the outer wall of the mounting plate 4. Finally, a telescopic rod 17 is set to prevent the spring 20 from deforming. During the installation process, the spring 20 may be deformed due to excessive external force, affecting its normal operation. The setting of the telescopic rod 17 is to prevent this from happening.
[0026] Reference Figure 1 , Figure 2 and Figure 3 A symmetrical stabilizing plate 21 is fixedly connected to one side of the outer wall of the muffler body 1, and a telescopic rod 22 is fixedly connected to the upper surface of the stabilizing plate 21; an insert block 23 is fixedly connected to the upper surface of the telescopic rod 22, and the insert block 23 is slidably connected to the connecting block 15, and a spring 3 24 is sleeved on the outer wall of the telescopic rod 22;
[0027] Specifically, when the block 19 is pressed and retracted, the reaction force generated by the spring 3 24 can drive the plug block 23, thereby lifting the connecting block 15. In the process of pushing the plug block 23, the telescopic rod 22 can adjust the length so that the plug block 23 remains stable during operation. When the connecting block 15 is lifted, pushing the plug block 23 can drive the mounting plate 4. In this way, the mounting plate 4 can be quickly separated from the outer wall of the main housing 7 to achieve disassembly. This design greatly improves the usability of the device and reduces the difficulty of the disassembly process.
[0028] Working principle: When the silencer needs to be dustproof and waterproof, the mounting plate 4 is first mounted on the outer wall of the mounting column 16. At this time, the reaction force of the second spring 20 drives the sliding block 18 to move. At this time, the movement of the sliding block 18 facilitates the effect of pushing the card block 19 to engage with the outer wall of the mounting plate 4 for installation. The setting of the telescopic rod 17 facilitates the effect of preventing the second spring 20 from deforming.
[0029] Secondly, when in use, the gas is discharged into the inside of the gas outlet pipe 2 5 through the gas outlet hole 1 3, and then discharged into the inside of the main shell 7 through the gas outlet hole 2 6. At this time, the gas inside the main shell 7 will push the sliding ring 8 to slide inside the main shell 7, and the limiting frame 9 is driven to slide through the sliding ring 8, thereby achieving the effect of driving the fixing ring 1201 on the lower surface of the connecting rod 11 to slide. At this time, the cleaning brush 1202 is driven by the fixing ring 1201 to clean the dust on the outer wall of the gas outlet hole on the outer wall of the main shell 7. At this time, the cleaning brush 1202 is quickly reset by the spring 10, and the setting of the rainproof top 14 can further prevent the effect of water showering the silencer body 1;
[0030] Again, when disassembly is required, the card block 19 is pressed to retract into the installation column 16. At this time, the reaction force of the spring three 24 is used to drive the plug block 23 to lift the connecting block 15. At this time, the setting of the telescopic rod two 22 is used to facilitate the stable operation of the plug block 23. The connecting block 15 is pushed by the plug block 23, so as to facilitate the installation plate 4 to quickly detach from the outer wall of the main shell 7 for disassembly.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
