DETAILED DESCRIPTION

[0021] like Figure 1-4 As shown, a natural gas pipeline external oil pollution cleaning device includes a workbench 1 and a plurality of supporting legs 2 installed at the bottom thereof, and also includes: a lifting cleaning mechanism and a plug-in installation mechanism; the lifting cleaning mechanism includes a fixed vertical plate 3 installed on the top of the workbench 1, a servo motor 301 is fixedly connected to the top of the outer wall of the fixed vertical plate 3, a square slide groove is opened on one side of the fixed vertical plate 3, a reciprocating screw 302 is fixedly connected to the output end of the servo motor 301, and the end of the reciprocating screw 302 away from the servo motor 301 rotates and extends to the inside of the square slide groove, the outer wall of the reciprocating screw 302 is located in the inner thread of the square slide groove and is connected to a thread block 303, the top and bottom of the thread block 303 are fixedly connected to a protective plate 304, and the bottom end of the protective plate 304 located at the bottom of the thread block 303 slides and extends to the outside of the bottom of the workbench 1;

[0022] The utility model is further described in detail. A sliding groove is provided on the workbench 1. The bottom of the protective plate 304 slides and extends to the outside of the bottom of the workbench 1 through the sliding groove. The outer wall of the threaded block 303 and the inner wall of the square sliding groove are slidably fitted. A mounting opening is provided on one side of the threaded block 303, and the outer wall of the mounting block 4 and the inner wall of the mounting opening are slidably fitted.

[0023] Through the setting of the above technical solution, in specific use: when the staff cleans the outer wall of the pipeline, the pipeline is placed inside the cleaning ring 401, and then the servo motor 301 is turned on. When the servo motor 301 works, the reciprocating screw 302 is driven to rotate accordingly. According to the threaded connection between the threaded block 303 and the reciprocating screw 302, the threaded block 303 can be moved downward, and then the threaded block 303 and the cleaning ring 401 are driven to move downward, so that according to the sliding fit of the multiple cleaning brushes on the inner wall of the cleaning ring 401 and the outer wall of the pipeline, the outer wall is scraped and cleaned up and down reciprocatingly;

[0024] like Figure 1-4 As shown, the plug-in installation mechanism includes a mounting block 4, a sliding rod 402 is slidably connected to the top of the outer wall of the threaded block 303, tension springs 403 are fixedly connected to the outer walls of the sliding rod 402 on both sides, a protective shell 404 is fixedly connected to the top of the sliding rod 402, a cleaning ring 401 is fixedly connected to one side of the mounting block 4, a plurality of cleaning brushes are connected to the inner wall of the cleaning ring 401, a limiting slide groove 405 is provided on the top of the mounting block 4, a socket 406 is provided inside the limiting slide groove 405, a mounting magnetic block 407 is fixedly connected to the bottom end of the sliding rod 402, and a fixed magnetic block 408 is fixedly connected to the inside of the socket 406;

[0025] The utility model further specifically describes that the outer wall of the sliding rod 402 and the inner wall of the limiting slide groove 405 are slidingly fitted, the sliding rod 402 and the plug hole 406 are correspondingly slidingly arranged, and the mounting magnetic block 407 and the fixed magnetic block 408 are correspondingly arranged with opposite poles attracting each other;

[0026] By setting the above technical solution, in specific use: when the cleaning ring 401 is damaged and needs to be replaced, the protective shell 404 is pulled upward to drive the sliding rod 402 to slide upward, so that the sliding rod 402 is disengaged from the socket 406 on the mounting block 4, and the fixing effect of the mounting block 4 and the threaded block 303 is released, and then the mounting block 4 can be directly taken out by sliding, thereby disassembling the cleaning ring 401;

[0027] When the cleaning ring 401 is installed, the mounting block 4 on one side of the cleaning ring 401 is directly inserted into the mounting opening on the threaded block 303. At this time, the limiting slide groove 405 and the sliding plug rod 402 are in sliding contact. When the bottom end of the sliding plug rod 402 corresponds to the position of the insertion hole 406, the sliding plug rod 402 is slidably inserted into the insertion hole 406 according to the polar attraction between the mounting magnetic block 407 and the fixed magnetic block 408, and the mounting block 4 can be fixed, so that the cleaning ring 401 is installed. Through the setting of this structure, the cleaning ring 401 can be disassembled at will, so that the staff can replace it when the cleaning effect is not good during the long-term use of the cleaning ring 401. At the same time, according to the sliding plugging effect of the sliding plug rod 402, the disassembly and installation of the cleaning ring 401 is simplified, and the work efficiency of the staff in installing, disassembling and replacing the cleaning ring 401 is correspondingly improved.

[0028] It should be noted that the bottom of the protective shell 404 does not fit with the top of the outer wall of the threaded block 303 in the initial state, and only fits with the outer wall of the threaded block 303 when the sliding rod 402 is inserted into the inside of the insertion hole 406, and at the same time, the attraction force between the mounting magnetic block 407 and the fixed magnetic block 408 is greater than the elastic tension of the tension spring 403;

[0029] In summary, this device for cleaning the external oil pollution of a natural gas pipeline can disassemble the cleaning ring 401 at will, so that the staff can replace it when the cleaning effect is poor during the long-term use of the cleaning ring 401. At the same time, according to the sliding plug-in function of the sliding plug rod 402, the disassembly and installation of the cleaning ring 401 is simplified, and the work efficiency of the staff in installing, disassembling and replacing the cleaning ring 401 is correspondingly improved.
