[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] See attached document Figure 1 -Appendix Figure 4The present invention provides an intelligent ventilation and dust removal system for subway tunnels, including a dust removal box 1, a plurality of support legs 2 fixedly connected to the bottom of the dust removal box 1, an air inlet pipe 3 on one side of the dust removal box 1, an air outlet pipe 4 on the other side of the dust removal box 1, a plurality of air outlets 5 on one side of the air outlet pipe 4, a purification mechanism inside the dust removal box 1, and a dust removal mechanism inside the air inlet pipe 3. The purification mechanism includes multiple positioning frames 6, all of which are fixedly embedded inside the dust collection box 1. Filter plates 7 are provided on both sides of each positioning frame 6, and purification boxes 8 are embedded inside each positioning frame 6. A base plate 9 is fixedly provided at the bottom of each purification box 8, located at the bottom of the dust collection box 1. Two crossbars 10 are provided at the bottom of the dust collection box 1, located on the front and rear sides of the base plates 9 respectively. Mounting plates 11 are provided on the outer sides of each of the two crossbars 10. Mounting frames 12 are provided on the front and rear sides of the dust collection box 1. The frame 12 is fitted onto the outside of the mounting plate 11. Two snap-fit ​​rods 13 are embedded inside the mounting frame 12. Snap-fit ​​grooves are opened on both sides of the mounting plate 11. The snap-fit ​​rods 13 match the snap-fit ​​grooves. Two movable frames 14 are provided on the top of the mounting frame 12. The two movable frames 14 are fixedly connected to the two snap-fit ​​rods 13 respectively. Springs 15 are provided on both sides of the mounting frame 12. The two springs 15 are fixedly connected to the inside of the two movable frames 14 and fitted onto the outside of the snap-fit ​​rods 13 respectively. A lever 16 is provided on the front side of the two movable frames 14. In this embodiment, when the device is working, multiple purification boxes 8 purify the air. After purification, the air is discharged to reduce the harm caused by harmful air to the staff. When it is necessary to replace the purification box 8, the user pushes the lever 16 outward to move the two moving frames 14 outward. The outward movement of the moving frames 14 compresses the two springs 15, causing the locking rod 13 to disengage from the locking groove, thus making it easy for the user to remove the multiple purification boxes 8. Similarly, when it is necessary to replace, the user pulls the lever 16 outward to insert the new purification box 8 into the dust collection box 1, and then releases the lever 16 to insert the locking rod 13 into the locking groove to position and install the purification box 8. To achieve the purpose of ventilation and dust removal, this device adopts the following technical solution: A drive motor 17 is installed on one side of the exhaust duct 4. A drive shaft 18 is fixedly connected to the output end of the drive motor 17. The drive shaft 18 extends into the interior of the exhaust duct 4. A blower fan blade 19 is fixedly sleeved on the outside of the drive shaft 18. A filter screen 20 is embedded inside the air inlet duct 3. A connecting ring 21 is installed on one side of the filter screen 20. Multiple scrapers 22 are fixedly connected to the outside of the connecting ring 21. A servo motor 23 is installed on the top of the dust collection box 1. A drive rod 24 is fixedly connected to the output end of the servo motor 23. A first... A connecting shaft 26 is embedded inside the transmission wheel 25 and the filter screen 20. The connecting shaft 26 is fixedly embedded inside the connecting ring 21. A second transmission wheel 27 is fixedly sleeved on the outside of the connecting shaft 26. A conveyor belt is sleeved on the outside of the first transmission wheel 25 and the second transmission wheel 27. The first transmission wheel 25 and the second transmission wheel 27 are driven and connected by the conveyor belt. A collection box 28 is provided at the bottom of the air inlet pipe 3. A through groove is opened at the bottom of the air inlet pipe 3. The through groove is connected to the collection box 28. A protective cover 29 is provided on the top of the dust collector 1. The protective cover 29 is sleeved on the outside of the first transmission wheel 25 and is movably connected to the transmission rod 24 through a rolling bearing. When the user starts the drive motor 17, the drive motor 17 causes the drive shaft 18 and the blower blades 19 to rotate. The rotating blower blades 19 draw in air from the air inlet pipe 3 and then exhaust it from the air outlet pipe 4. When it is necessary to clean the filter screen 20, the user starts the servo motor 23. The servo motor 23 drives the drive rod 24 and the first drive wheel 25 to rotate. The rotation of the first drive wheel 25 drives the second drive wheel 27 and the connecting shaft 26 to rotate. The rotation of the connecting shaft 26 drives the connecting ring 21 and the scraper 22 to rotate. Multiple scrapers 22 scrape off the dust adhering to the surface of the filter screen 20, which falls into the collection box 28 through the channel for easy collection by the user later.

[0022] The usage process of this utility model is as follows: The user starts the drive motor 17, which causes the drive shaft 18 and the blower blade 19 to rotate. The blower blade 19 draws air in from the air inlet pipe 3 and then discharges it from the air outlet pipe 4. When it is necessary to clean the filter screen 20, the user starts the servo motor 23. The servo motor 23 drives the drive rod 24 and the first drive wheel 25 to rotate. The rotation of the first drive wheel 25 drives the second drive wheel 27 and the connecting shaft 26 to rotate. The rotation of the connecting shaft 26 drives the connecting ring 21 and the scraper 22 to rotate. Multiple scrapers 22 scrape off the dust adhering to the surface of the filter screen 20, which falls into the collection box 28 through the channel. Inside, for easy collection by the user, when the device is working, multiple purification boxes 8 purify the air. After purification, the air is discharged, reducing the harm caused by harmful air to the staff. When it is necessary to replace the purification box 8, the user moves the lever 16 outward, causing the two moving brackets 14 to move outward. The outward movement of the moving brackets 14 compresses the two springs 15, causing the locking rod 13 to disengage from the locking groove, thus making it easy for the user to remove the multiple purification boxes 8. Similarly, when it is necessary to replace, pull the lever 16 outward to insert the new purification box 8 into the dust collection box 1, and then release the lever 16 to insert the locking rod 13 into the locking groove for positioning and installation of the purification box 8.

[0023] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
