[0002] The air duct system on a railway locomotive or train usually uses pipes to transport wind. Due to the good sealing properties of the pipes, the loss of wind during the transportation process can be avoided.
[0003] In order to reduce dust in wind transportation, filters are usually installed at the air inlet or outlet to block the dust. However, as the use time increases, the gradually increasing dust will clog the mesh of the filter, which is inconvenient for personnel to clean and requires a high frequency of cleaning.
[0004] Therefore, it is necessary to propose a dust-proof plugging structure for train pipes to solve the above problems. Utility Model Content

[0013] Technical effects and advantages of this utility model:
[0014] 1. In the actual operation of the present invention, when wind enters the pipe body, it will pass through the inside of the mesh tube. The mesh tube and the filter disc will intercept and collect dust and impurities, preventing dust and impurities from entering the second half of the pipe body or the air outlet.
[0015] 2. When the mesh tube gathers some dust and impurities, it will block the mesh of the mesh tube and the filter disc. At this time, the wind is not easy to pass through, so the wind is gathered inside the mesh tube and the fixed tube. As the wind pressure increases, the wind will push the mesh tube to slide inside the fixed tube, causing the mesh tube to extend out of the fixed tube, allowing the remaining unblocked mesh of the mesh tube to extend out, facilitating the output of wind, and at the same time expanding the space between the mesh tube and the fixed tube to collect more dust.
[0016] 3. At the same time, the action of wind will cause the second spring on the filter disc to swing left and right, while entangling the dust, it can gather the dust on the nearby mesh on itself, thereby reducing the dust from gathering on the mesh. At the same time, the shaking of the second spring can make the dust shake to avoid being blocked in the mesh. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] The utility model provides Figures 1 to 4 The dust-proof plugging structure for a pipe used in a train is shown, comprising a pipe body 1, with a dust-proof mechanism 2 installed inside the pipe body 1. The train utilizes the pipe body 1 to transport hot air or cold air. By installing the dust-proof mechanism 2 at the air inlet of the pipe body 1, dust and impurities in the wind can be collected to prevent them from entering the pipe body 1 and causing cleaning difficulties.
[0024] The dust-proof mechanism 2 includes a fixed cylinder 5, a mesh cylinder 6 is telescopically and slidably arranged inside the fixed cylinder 5, a filter disc 11 is installed at the bottom end of the mesh cylinder 6, and a plurality of second springs 12 are fixed on the top of the filter disc 11. The plurality of second springs 12 are vertically fixed on the filter disc 11, and the plurality of second springs 12 extend into the interior of the mesh cylinder 6, and the top of the mesh cylinder 6 is connected to the outside world.
[0025] A first outer disk 3 is fixed to the top outer side of the pipe body 1, and a second outer disk 4 is fixed to the top outer side of the fixing tube 5. Corresponding through holes are provided on the first outer disk 3 and the second outer disk 4, and a fixing bolt is installed between the two corresponding through holes. The radius of the first outer disk 3 and the second outer disk 4 are consistent.
[0026] The pipe body 1 and the fixing cylinder 5 are connected to each other by fixing bolts.
[0027] Both ends of the fixed cylinder 5 are connected to the outside world, and a sliding groove 7 is provided inside the fixed cylinder 5. The sliding groove 7 is distributed along the height direction of the fixed cylinder 5, and a sliding block 8 is fixedly connected to the outside of the net cylinder 6. The sliding block 8 slides in the corresponding sliding groove 7, and a first spring 9 is fixedly connected between the top of the sliding block 8 and the top of the sliding groove 7.
[0028] In the actual operation of the present invention, when wind enters the pipe body 1, it will pass through the inside of the mesh tube 6. The mesh tube 6 and the filter plate 11 intercept and collect dust and impurities, preventing dust and impurities from entering the rear half of the pipe body 1 or the air outlet.
[0029] When the mesh tube 6 gathers some dust and impurities, it will block the mesh of the mesh tube 6 and the filter disc 11. At this time, the wind is not easy to pass through, so the wind is gathered inside the mesh tube 6 and the fixed tube 5. As the wind pressure increases, the wind will push the mesh tube 6 to slide inside the fixed tube 5, so that the mesh tube 6 extends out of the fixed tube 5, allowing the remaining unblocked mesh of the mesh tube 6 to extend, which is convenient for the output of wind and expands the space between the mesh tube 6 and the fixed tube 5 to collect more dust.
[0030] At the same time, the action of wind will cause the second spring 12 on the filter plate 11 to swing left and right, which will entangle the dust and gather the dust on the nearby mesh on itself. At the same time, the shaking of the second spring 12 can make the dust shake to avoid being blocked in the mesh.
[0031] A connecting plate 10 is fixed to the outside of the filter disc 11, and a fixing screw 13 is provided on the outside of the connecting plate 10. A connecting hole 14 for threaded engagement of the fixing screw 13 is opened on the outside of the fixing cylinder 5. The filter disc 11 and the mesh cylinder 6 can be disassembled to facilitate subsequent personnel to clean the collected dust.
[0032] The plurality of second springs 12 are all parallel to the length direction of the net cylinder 6 .
