The two sets of retaining frames 6 are fixedly connected to the corresponding air ducts 2 via telescopic tubes 7. An installation frame 3 is slidably installed inside the installation box 1, and a lead screw 16 is rotatably installed inside the installation box 1. The lead screw 16 passes through the installation frame 3 and is threadedly connected to the installation frame 3. Two sets of symmetrically distributed installation frames 4 are fixedly installed on the installation frame 3. Each set of installation frames 4 has two sets of symmetrically distributed slots 5. The two sets of retaining frames 6 can be movably engaged with the installation frames 4 through the slots 5. The two sets of installation frames 4 are equipped with... The installation box 1 is equipped with multiple sets of equidistantly distributed guide plates 8. Two sets of symmetrically distributed mounting plates 14 are located inside the mounting box 14. Fixing blocks 35 are slidably installed within the mounting plates 14. A fixing seat 17 is located below the fixing block 35, and a fixing frame 21 is slidably installed within the fixing seat 17. Multiple sets of cleaning brushes 22, corresponding to the guide plates 8, are located below the fixing frame 21. Two adjacent sets of cleaning brushes 22 are respectively attached to the sides of the corresponding guide plates 8. Two sets of symmetrically distributed dust collection boxes 15 are slidably installed inside the mounting box 1, located on both sides of the air duct 2. During use, air enters the bus through the air duct 2 on the mounting box 1. The air direction is adjusted by the guide plates 8 on the mounting frame 4. Dust and impurities in the air inevitably adhere to the guide plates 8. After the guide plate 8 in the mounting frame 4 has been used for a period of time, the starting mechanism in the mounting box 1 is activated to move the clamping frame 6 away from the mounting frame 4, and the motor inside the mounting box 1 is activated to drive the lead screw 16 to rotate, so that the mounting frame 3 drives the two sets of mounting frames 4 to slide in the mounting box 1, completing the replacement of the two sets of mounting frames 4. After the new mounting frame 4 is aligned with the two sets of clamping frames 6, the mounting frame 4, guide plate 8 and two sets of air ducts 2 are reconnected through clamping frames 6 and telescopic tubes 7, and the air inlet and outlet structure continues to work. The guide plate 8 is rotatably connected to the mounting frame 4 through the mounting shaft 9. The mounting shaft 9 is sleeved with a synchronous pulley 10. The mounting frame 4 is equipped with a synchronous belt 11, which is connected to multiple sets of synchronous pulleys 10 for transmission. The middle mounting shaft 9 is sleeved with a first gear 12, which slides inside the mounting frame 4. A first rack 13 is installed, meshing with a first gear 12. A threaded rod 23 is rotatably installed inside the mounting plate 14, passing through and threadedly connecting to a fixing block 35. Two sets of symmetrically distributed first slide rods 24 are fixedly installed inside the fixing seat 17. A fixing frame 21 is slidably sleeved with each of the two sets of first slide rods 24. Two sets of symmetrically distributed first springs 26 are sleeved on the first slide rods 24, with their ends fixedly connected to the fixing frame 21 and the fixing seat 17, respectively. A first cam 27 is rotatably installed inside the fixing seat 17. A push plate 25 is fixedly installed on the fixing frame 21. The first cam 27 is fitted against the push rod. The replaced mounting frame 4 and guide plate 8 are aligned with one side of the mounting plate 14.In the mounting box 1, the cylinder drives the mounting plate 14 downward, causing the cleaning brush 22 to insert into the mounting frame 4. Cleaning brushes 22 are attached to both sides of each guide plate 8. The motor in the mounting plate 14 drives the threaded rod 23 to rotate. Under the limiting action of the mounting plate 14, the fixing block 35 causes the lower fixing seat 17, fixing frame 21, and cleaning brushes 22 to slide on the mounting plate 14. Inside the fixing seat 17, the motor drives the first cam 27 to rotate, and in conjunction with the push plate 25, the first slide rod 24, and the first spring 26, the fixing frame 21 drives the cleaning brushes 22 to reciprocate on the fixing seat 17, completing the cleaning of dust and impurities adhering to the guide plates 8.
[0026] like Figure 8 and Figure 9 As shown, the fixed base 17 is rotatably connected to the fixed block 35 via an adjusting rod 18. A second gear 19 is sleeved on the adjusting rod 18. A second rack 20 is slidably installed inside the fixed block 35, and the second rack 20 meshes with the second gear 19. A movable frame 28 is slidably installed on the mounting plate 14. A screw 29 is rotatably installed inside the mounting plate 14, and the screw 29 passes through the movable frame 28 and is threadedly connected to the movable frame 28. A movable plate 30 is slidably installed inside the movable frame 28, and multiple sets of equidistantly distributed... Roller brushes 31, multiple sets of roller brushes 31 are respectively fitted with two corresponding sets of cleaning brushes 22. A second slide rod 32 is fixedly installed inside the movable frame 28. The movable plate 30 is slidably sleeved with the second slide rod 32. Two sets of symmetrically distributed second springs 33 are sleeved on the second slide rod 32. The two ends of the two sets of second springs 33 are respectively fixedly connected to the corresponding movable plate 30 and the movable frame 28. A second cam 34 is rotatably installed inside the movable frame 28. The second cam 34 is fitted with the movable plate 30. After the cleaning brushes 22 have been used for a period of time... Afterwards, the mounting plate 14 drives the fixing block 35, fixing seat 17, fixing frame 21, and cleaning brush 22 to move upwards. The cylinder in the fixing block 35 drives the second rack 20 to slide, which, in conjunction with the second gear 19, achieves a 90-degree rotation of the fixing seat 17, fixing frame 21, and cleaning brush 22. At this time, the cleaning brush 22 is aligned with the corresponding roller brush 31, and the roller brush 31 is located between the two sets of cleaning brushes 22 and is in close contact with them. The motor in the mounting plate 14 drives the screw 29 to rotate, causing the moving frame 28 to slide. The motor in the moving frame 28 drives... The rotation of the second cam 34, in conjunction with the second slide bar 32 and the second spring 33, causes the moving plate 30 to drive multiple sets of roller brushes 31 to reciprocate on the moving frame 28, and to scrape against the cleaning brushes 22 that are in contact with it. At the same time, the motor in the fixed base 17 can continue to drive the first cam 27 to rotate, so that the cleaning brushes 22 reciprocate under the drive of the fixed frame 21. Under the interaction of the roller brushes 31 and the cleaning brushes 22, the impurities attached to the cleaning brushes 22 are shaken off and fall into the dust collection box 15 corresponding to the mounting plate 14.
[0027] This utility model provides a bus air duct outlet structure. The specific working principle is as follows: During use, air enters the bus through the air duct 2 on the mounting box 1. The air direction is adjusted by the guide plate 8 on the mounting frame 4. Dust and impurities in the air inevitably adhere to the guide plate 8. After a period of use, the guide plate 8 in one set of mounting frames 4 is activated. The starting mechanism in the mounting box 1 moves the retaining frame 6 away from the mounting frame 4, and the motor inside the mounting box 1 drives the lead screw 16 to rotate. This causes the mounting bracket 3 to slide the two sets of mounting frames 4 within the mounting box 1, completing the swap of the two sets of mounting frames 4. The new mounting frame 4 is then aligned with the two sets of retaining frames 6 and passed through the retaining frames again. 6 and telescopic tube 7 complete the connection between the mounting frame 4, guide plate 8 and two sets of air ducts 2, and continue the air inlet and outlet structure. The replaced mounting frame 4 and guide plate 8 are aligned with the mounting plate 14 on one side. The cylinder in the mounting box 1 drives the mounting plate 14 to move down and inserts the cleaning brush 22 into the mounting frame 4. Cleaning brushes 22 are attached to both sides of each set of guide plates 8. The motor in the mounting plate 14 drives the threaded rod 23 to rotate. Under the limiting action of the mounting plate 14, the fixing block 35 drives the lower fixing seat 17 and fixing frame 21 and the cleaning brush 22 to slide on the mounting plate 14. The motor in the fixing seat 17 drives the first cam 27 to rotate, and The push plate 25, the first slide rod 24, and the first spring 26 work together to cause the fixing frame 21 to drive the cleaning brush 22 to reciprocate on the fixing seat 17, thus cleaning the dust and impurities attached to the guide plate 8 that it is in contact with. After the cleaning brush 22 has been used for a period of time, the mounting plate 14 drives the fixing block 35, the fixing seat 17, the fixing frame 21, and the cleaning brush 22 to move upward. The cylinder in the fixing block 35 drives the second rack 20 to slide, which, together with the second gear 19, realizes the 90-degree rotation of the fixing seat 17, the fixing frame 21, and the cleaning brush 22. At this time, the cleaning brush 22 is aligned with the corresponding roller brush 31, and the roller brush 31 is located between the two sets of cleaning brushes 22 and is aligned with the roller brush 31. Upon contact, the motor in the mounting plate 14 drives the screw 29 to rotate, causing the movable frame 28 to slide. The motor in the movable frame 28 drives the second cam 34 to rotate, which, together with the second slide rod 32 and the second spring 33, causes the movable plate 30 to drive multiple sets of roller brushes 31 to reciprocate on the movable frame 28 and scrape against the cleaning brush 22 that is in contact with it. At the same time, the motor in the fixed base 17 can continue to drive the first cam 27 to rotate, causing the cleaning brush 22 to reciprocate under the drive of the fixed frame 21. Under the interaction of the roller brushes 31 and the cleaning brush 22, the impurities attached to the cleaning brush 22 are shaken off and fall into the dust collection box 15 corresponding to the mounting plate 14.
