[0027] Refer toFigures 1-5 , a natural gas filtering pipeline, comprising a filtering pipeline main body 1: One end of the filtering pipeline main body 1 is fixedly connected with an air inlet pipe 2, and the other end of the filtering pipeline main body 1 is fixedly connected with an air outlet pipe 3. One end of the air inlet pipe 2 and the air outlet pipe 3 are both fixedly connected with a flexible connecting pipe 4. An adjusting mechanism 5 is arranged on the outer surface of one side of the flexible connecting pipe 4. The adjusting mechanism 5 includes a fixed block 501 fixedly connected to one side of the air inlet pipe 2. A rack belt 502 is fixedly connected to the lower side of the fixed block 501. The rack belt 502 is movably connected to one side of the outer surface of the flexible connecting pipe 4. A through groove 503 is opened on one side of the fixed block 501. One end of the rack belt 502 penetrates through the through groove 503 and is movably connected with the through groove 503. A groove body 504 is fixedly connected to one side of the fixed block 501. A servo motor 505 is fixedly connected to the inner wall of one side of the groove body 504. The output end of the servo motor 505 is fixedly connected with a rotating shaft 506. The rotating shaft 506 penetrates through one side wall of the fixed block 501 and is rotatably connected with the fixed block 501. A gear 507 is fixedly connected to the outer surface of the rotating shaft 506. The gear 507 is meshed with the rack belt 502. Both the gear 507 and the rack belt 502 are made of rubber. A battery box 6 is fixedly connected to the middle of one side of the groove body 504. A cover plate 7 is screwed to one side of the battery box 6. A storage battery 8 is installed on the inner wall of the battery box 6. The storage battery 8 is electrically connected with the servo motor 505. When it is necessary to adjust the diameter of the flexible connecting pipe 4 to connect the filtering pipeline main body 1 with an external connecting pipeline, the servo motor 505 is started to drive the gear 507 to rotate through the rotating shaft 506. The gear 507 rotates and meshes with the rack belt 502, thereby driving the rack belt 502 to move and contract on the outer surface of the flexible connecting pipe 4. The contraction of the rack belt 502 changes the diameter of the flexible connecting pipe 4, so that the diameter of the flexible connecting pipe 4 can be adjusted, and then it is convenient for the filtering pipeline main body 1 to be installed with external connecting pipelines of different diameters through the flexible connecting pipe 4, enhancing the applicability and flexibility of the filtering pipeline main body 1.

[0028] On the inner wall of one side of the filtering pipeline main body 1 close to the air inlet pipe 2, a filter net 9 is installed. The diameter of the filter net 9 is adapted to the diameter of the inner wall of the filtering pipeline main body 1. On the upper surface of one side of the filtering pipeline main body 1, a slot 10 is opened. An arc-shaped plate 11 is inserted into the inner wall of the slot 10. On the inner wall of the arc-shaped plate 11, clamping grooves 12 are symmetrically opened. A clamping block 13 is clamped in the inner wall of the clamping groove 12. The clamping block 13 is fixedly connected to one side of the filter net 9. In the middle of the lower surface of the filter net 9, a plug rod 14 is fixedly connected. On one side of the filtering pipeline main body 1 close to the plug rod 14, a jack 15 is opened. On the outer surface of the lower part of the plug rod 14, a thread groove 16 is opened. A rotating block 17 is threadedly connected to the outer surface of the thread groove 16. On the lower sides of both side walls of the arc-shaped plate 11, lifting plates 18 are fixedly connected. On both side walls of the arc-shaped plate 11, sealing gaskets 19 are fixedly connected. On the upper surface of the rotating block 17, a sealing ring 20 is fixedly connected. The diameter of the inner wall of the sealing ring 20 is adapted to the diameter of the plug rod 14. The natural gas is filtered through the filter net 9, so as to prevent impurities in the natural gas from adhering to the inside of the filtering pipeline main body 1 and affecting the use of the filtering pipeline main body 1. When it is necessary to remove the filter net 9 for cleaning, rotate the rotating block 17 to drive it to move downward on the outer surface of the plug rod 14, so that the plug rod 14 is no longer limited to the inner wall of the jack 15, and then the filter net 9 is no longer limited to the inner wall of the filtering pipeline main body 1. Push up the lifting plate 18 to drive the arc-shaped plate 11 to move upward in the inner wall of the slot 10, thereby driving the filter net 9 to move upward, so that the filter net 9 is separated from the filtering pipeline main body 1, and then the filter net 9 is removed to clean the impurities adhering to its surface. The disassembly and installation are relatively convenient, and the filter net 9 can be removed from the arc-shaped plate 11 through the clamping groove 12 and the clamping block 13 for replacement, which is convenient to use.

[0029] Working principle: When it is necessary to adjust the diameter of the flexible connecting pipe 4 to connect the filtering pipeline main body 1 with an external connecting pipeline, start the servo motor 505 to drive the gear 507 to rotate through the rotating shaft 506. The gear 507 rotates and meshes with the rack belt 502, thereby driving the rack belt 502 to move and contract on the outer surface of the flexible connecting pipe 4. The contraction of the rack belt 502 changes the diameter of the flexible connecting pipe 4, so that the diameter of the flexible connecting pipe 4 can be adjusted, and then it is convenient for the filtering pipeline main body 1 to be installed with external connecting pipelines of different diameters through the flexible connecting pipe 4, enhancing the applicability and flexibility of the filtering pipeline main body 1.
