[0003] Traditional cleaning methods for cooling devices are mostly single-point cleaning or manual cleaning. Each single-point cleaning tool can only handle a small area at a time. When facing large-area cooling devices, it requires a lot of time and manpower, and the cleaning efficiency is extremely low. Manual cleaning not only has a high labor intensity, but also it is difficult to ensure the uniformity and comprehensiveness of cleaning, and it is easy to have missed cleaning areas. Especially when dealing with protrusions, depressions or irregular shapes on the surface of the cooling devices, since it is difficult to precisely make the cleaning tool closely fit the surface by manual operation, the dust in these parts is difficult to be completely removed, and the cleaning effect is greatly reduced.

[0004] In view of this, this application proposes a cleaning mechanism for EMU cooling devices. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present application in detail with reference to the accompanying drawings of the specification.

[0022] Refer to Figures 1-4, an embodiment of the present application provides a cleaning mechanism for the heat dissipation device of a multiple unit train, including a fixed frame 1 and an air extraction structure for dust suction. A cleaning frame 2 is fixedly connected to the lower end surface of the fixed frame 1, and a cleaning mechanism for cleaning the dust on the surface of the heat dissipation device of the multiple unit train is arranged inside the cleaning frame 2; the cleaning mechanism includes a pair of ventilation nets 13 fixedly connected inside the cleaning frame 2, and a driving component located between the two ventilation nets 13. A first brush block 14 is arranged below the ventilation net 13, and a plurality of second brush blocks 15 are arranged on the periphery of the first brush block 14. The driving component is used to drive the first brush block 14 and the plurality of second brush blocks 15 to rotate. By synchronously performing circular motion of the plurality of second brush blocks 15 and the first brush block 14, the cleaning area can cover the heat dissipation device more widely. Compared with the single-point or manual cleaning method, the cleaning efficiency is greatly improved, ensuring that the dust on the surface of the heat dissipation device can be effectively removed in a short time, helping to maintain the normal heat dissipation function of the heat dissipation device, and ensuring the stable operation of the device.

[0023] The driving component includes a fixing plate 12 fixedly connected between the two ventilation nets 13. An installation opening 16 is penetrated inside the fixing plate 12, and a plurality of extension openings 17 are opened on the inner wall of the installation opening 16. A gear ring 18 is arranged inside the installation opening 16, and a gear block 19 is arranged inside the extension opening 17. The gear ring 18 meshes with the plurality of gear blocks 19. By driving the rotation of the gear ring 18 to drive the rotation of the plurality of gear blocks 19, the rotation of the gear ring 18 and the gear block 19 drives the rotation of the first brush block 14 and the second brush block 15. The operation is simple and it is more convenient to use.

[0024] The upper end of the first brush block 14 penetrates the lower ventilation net 13 and is fixedly connected to the gear ring 18. An arc-shaped sleeve 21 is fixedly connected to the upper end surface of the second brush block 15. A spherical block 22 is movably clamped inside the arc-shaped sleeve 21. A fixing block 23 is fixedly connected to the upper part of the outer wall of the spherical block 22, and the upper end of the fixing block 23 penetrates the lower ventilation net 13 and is fixedly connected to the gear block 19. When encountering protrusions, depressions or irregular shapes on the surface of the heat dissipation device, the spherical block 22 will flip inside the arc-shaped sleeve 21, driving the second brush block 15 to adjust the angle and fit with the surface of the heat dissipation device. This adaptive structure enables the second brush block 15 to better adapt to the changes in different angles and shapes of the surface of the heat dissipation device, avoiding cleaning omissions or poor cleaning effects caused by uneven surfaces, further improving the cleaning effect, and ensuring that all parts of the heat dissipation device can be effectively cleaned.

[0025] Refer to Figure 4, a colloid column 24 is fixedly connected between the arc-shaped sleeve 21 and the spherical block 22. After cleaning, the colloid column 24 returns to its initial state and drives the arc-shaped sleeve 21 and the second brush block 15 back to their initial positions, enabling the cleaning device to quickly return to its initial state for convenient next use. Meanwhile, the stability and reliability of the cleaning device structure are ensured, the risk of reduced cleaning effect or equipment failure caused by structural deformation or position deviation is reduced, and the service life and reusable performance of the cleaning device are improved.

[0026] Refer to Figure 2 and Figure 3 , a motor 3 is fixedly connected to the upper end face of the fixed frame 1. A fixed rod 20 is rotatably connected inside the fixed frame 1, and the lower end of the fixed rod 20 penetrates through the upper ventilation net 13 and is fixedly connected to the gear ring 18. The output end of the motor 3 is fixedly connected to the fixed rod 20. The motor 3 drives the fixed rod 20 and the gear ring 18 to rotate, eliminating the need for manual cleaning and improving the efficiency of the device.

[0027] Refer to Figure 1 and Figure 2 , the air extraction structure includes an extension frame 4 fixedly connected to the outer wall of the fixed frame 1, and the fixed frame 1 is in communication with the extension frame 4. One end of the extension frame 4 is rotatably connected with a threaded cover 5 through threads. An exhaust fan group 6 is fixedly connected inside the threaded cover 5. A filter screen frame 7 is fixedly connected inside the threaded cover 5 near one end of the extension frame 4. The filter screen frame 7 is used to collect the dust cleaned, preventing the dust from flying around the heat dissipation device and causing secondary pollution.

[0028] A fixed frame 8 is fixedly connected inside the extension frame 4. A rotating rod 9 is rotatably connected to the lower end of the fixed frame 8. A fan blade 10 is fixedly connected to the outer wall of the rotating rod 9. A scraping strip 11 is fixedly connected to the lower end of the rotating rod 9, and the outer wall of the scraping strip 11 is in mutual fit with the inside of the filter screen frame 7. When the air passes through the filter screen frame 7, it blows the fan blade 10. The rotation of the fan blade 10 drives the rotating rod 9 and the scraping strip 11 to rotate synchronously. The rotation of the scraping strip 11 will stir the dust on the inner wall of the filter screen frame 7. The self-cleaning function of the filter screen frame 7 is realized by using the power of the ventilation air flow, preventing dust particles from blocking the filter screen frame 7, ensuring the smoothness of the ventilation system, thus continuously maintaining good ventilation and cleaning effects, reducing the risk of equipment failure and the decline of cleaning efficiency caused by filter screen blockage, and extending the maintenance cycle of the equipment.

[0029] Working principle: The staff installs the clamping blocks on the outer wall of the fixed frame 1 onto the handle with a specified length. When cleaning the dust on the surface of the heat dissipation device for the EMU, the motor 3 and the exhaust fan group 6 are started. The output end of the motor 3 rotates to drive the rotating rod 9 to rotate, and the rotating rod 9 rotates to drive the gear ring 18 inside the fixed plate 12 to rotate. Since the multiple gear blocks 19 inside the multiple extension ports 17 are meshed with the gear ring 18, the rotation of the gear ring 18 drives the multiple gear blocks 19 and the first brush block 14 to rotate synchronously. The rotation of the gear block 19 drives the fixed block 23, the spherical block 22, the arc-shaped sleeve 21 and the second brush block 15 to rotate synchronously. Through the rotation of the multiple second brush blocks 15 and the first brush block 14, a wider cleaning area of the heat dissipation device can be covered.

[0030] When encountering protrusions, depressions or irregular shapes on the surface of the heat dissipation device, the spherical block 22 will flip inside the arc-shaped sleeve 21, so that the second brush block 15 can adjust the angle and fit the surface of the heat dissipation device. At the same time, the colloid column 24 deforms, and the second brush block 15 can better adapt to the changes in different angles and shapes of the surface of the heat dissipation device, further improving the cleaning effect.

[0031] The exhaust fan group 6 works to exhaust air. The dust and air swept by the first brush block 14 and the second brush block 15 will pass through the two ventilation nets 13 and the fixed plate 12 and enter the fixed frame 1. The dust and air then enter the extension frame 4 through the fixed frame 1. Finally, the air passes through the filter frame 7 and the exhaust fan group 6 and is discharged outside the device, while the dust is isolated inside the filter frame 7. When the air passes through the filter frame 7, it will blow the fan blades 10. The rotation of the fan blades 10 drives the rotating rod 9 and the scraping strip 11 to rotate synchronously. The rotation of the scraping strip 11 will stir the dust on the inner wall of the filter frame 7 to prevent dust particles from blocking the filter frame 7 and affecting the ventilation and cleaning effects.

[0032] After the cleaning is completed, the device is taken out. The colloid column 24 returns to its initial state and drives the arc-shaped sleeve 21 and the second brush block 15 back to their initial positions. The motor 3 and the exhaust fan group 6 are turned off. The staff rotates and removes the threaded cover 5, and the threaded cover 5 brings out the filter frame 7. The staff cleans the dust inside the filter frame 7 and then reinstalls the filter frame 7 and the threaded cover 5.

[0033] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
