Side plates 30 are respectively provided on both sides of the support column 4. A first insertion block 31 penetrates through the side plate 30. First insertion slots 32 are respectively provided on both sides of the support column 4. One end of the first insertion block 31 is located in the corresponding first insertion slot 32. The other end of the first insertion block 31 is fixedly connected to an iron plate 34.

The magnetic ring 44 is located on the side of the iron plate 43 facing the support box 3;

[0039] When the fixed ring 17 moves in the vertical direction, the fixed ring 17 drives the stop plate 35 to slide vertically relative to the iron plate 34. By limiting the position of the iron plate 34 with the stop plate 35, it is ensured that the end of the first insertion block 31 away from the iron plate 34 is always located in the first slot 32, so that the support column 4 is fixed relative to the side plate 30 and the mounting seat 2. When it is necessary to disassemble the mounting seat 2 and the monitoring device body 1 from the support box 3, the staff presses the iron plate 43 to move. The iron plate 43 drives the movable plate 38 to move through the movable column 41, so that the movable plate 38 drives the second insertion block 39 to disengage from the second slot 40, releasing the limitation on the position of the fixed block 36, and the tension spring 42 is in a stretched state. At this time, the iron plate 43 is in contact with the magnet ring 44, and the magnet ring 44 and the iron plate 43 generate magnetic force, so that the movable column 41 and the movable plate 38 are fixed relative to the support box 3, and the second insertion block 39 remains in the state of disengaging from the second slot 40.

The staff drives the iron plate 34 to move away from the side plate 30, and the iron plate 34 is no longer magnetically attracted to the magnet bar 33. The iron plate 34 drives the end of the first insertion block 31 to disengage from the first slot 32, releasing the limitation on the position of the support column 4. The staff drives the support column 4 and the roller 5 to move downward relative to the mounting seat 2, so that the positioning block 28 disengages from the positioning groove 29, and then the removal of the support column 4 and the roller 5 can be completed, which is convenient for replacing the roller 5.

[0040] A method for using an on-line gas monitoring device in transformer oil according to this embodiment, using the on-line gas monitoring device in transformer oil as described above, includes the following steps:

[0041] Step 1: Drive the support sleeve 6 and the cleaning ring 7 to move downward through the position adjustment assembly, so that the cleaning ring 7 is in contact with the ground;

[0042] Step 2: The staff pushes the monitoring device body 1 to move, and the roller 5 rolls on the ground;

[0043] Step 3: During the movement of the monitoring device body 1, drive the support sleeve 6 and the cleaning ring 7 to rotate through the position adjustment assembly, and clean the stones and sundries on the ground through the rotating cleaning ring 7 to prevent the stones and sundries from being on the moving track of the roller 5.

[0044] Working principle: The position adjustment component drives the support sleeve 6 and the cleaning ring 7 to move downward so that the cleaning ring 7 contacts the ground. The staff member pushes the monitoring device body 1 to move, and the rollers 5 roll on the ground. During the movement of the monitoring device body 1, the position adjustment component drives the support sleeve 6 and the cleaning ring 7 to rotate. The rotating cleaning ring 7 clears the stones and sundries on the ground to prevent the stones and sundries from being on the moving track of the rollers 5, so that the monitoring device body 1 can move smoothly to the preset position, reducing the possibility of loosening of the electronic components in the monitoring device body 1;

[0045] When the monitoring device body 1 moves to the preset position, the hydraulic telescopic rod 11 drives the movable frame 8 to move downward. The movable frame 8 drives the support seat 9 and the anti-slip pad 12 to move downward through the connecting column 10, so that the bottom of the anti-slip pad 12 contacts the ground. The monitoring device body 1 is supported by the support seat 9 and the anti-slip pad 12 to reduce the possibility of the monitoring device body 1 shaking relative to the ground. When it is necessary to drive the monitoring device body 1 to move, the hydraulic telescopic rod 11 drives the movable frame 8 and the support seat 9 to move upward so that the anti-slip pad 12 no longer contacts the ground, and the movable frame 8 drives the second toothed plate 23 to move upward. The second toothed plate 23 drives the gear 22 to rotate. The gear 22 drives the lifting plate 16 and the fixed ring 17 to move downward through the first toothed plate 21. The lifting plate 16 slides relative to the guide post 20. Through the design of the guide post 20, the lifting plate 16 and the fixed ring 17 move smoothly in the vertical direction. The fixed ring 17 drives the support sleeve 6 and the cleaning ring 7 to move downward so that the bottom of the cleaning ring 7 contacts the ground, and the support sleeve 6 drives the slide plate 15 to slide relative to the chute 14. When it is necessary to drive the monitoring device body 1 to move, the servo motor 25 drives the rotating frame 26 and the second toothed ring 27 to rotate. The second toothed ring 27 drives the rotating sleeve 13 to rotate through the first toothed ring 24. The rotating sleeve 13 can drive the support sleeve 6 to rotate synchronously through the slide plate 15. The support sleeve 6 drives the guide ring 19 to slide in the guide groove 18, and the support sleeve 6 can drive the cleaning ring 7 to clean the ground;

[0046] When the fixed ring 17 moves in the vertical direction, the fixed ring 17 drives the stop plate 35 to slide vertically relative to the iron plate 34. By limiting the position of the iron plate 34 through the stop plate 35, it is ensured that the end of the first insertion block 31 away from the iron plate 34 is always located within the first slot 32, so that the support column 4 is fixed relative to the side plate 30 and the mounting seat 2. When it is necessary to disassemble the mounting seat 2 and the monitoring device body 1 from the support box 3, the staff presses the iron plate 43 to move. The iron plate 43 drives the movable plate 38 to move through the movable column 41, so that the movable plate 38 drives the second insertion block 39 to disengage from the second slot 40, releasing the limitation on the position of the fixed block 36, and the tension spring 42 is in a stretched state. At this time, the iron plate 43 and the magnet ring 44 are in contact, and the magnet ring 44 and the iron plate 43 generate magnetic force, so that the movable column 41 and the movable plate 38 are fixed relative to the support box 3, and the second insertion block 39 remains in the state of disengaging from the second slot 40. When all the second insertion blocks 39 are disengaged from the second slot 40, the staff drives the monitoring device body 1 and the mounting seat 2 to move upward through the lifting equipment, so that the mounting seat 2 drives the fixed block 36 to disengage from the positioning ring 37, and the mounting seat 2 drives the support column 4 and the roller 5 to be withdrawn from the support sleeve 6, and then the disassembly between the mounting seat 2 and the support box 3 can be completed. The staff drives the iron plate 34 to move away from the side plate 30, and the iron plate 34 is no longer magnetically attracted to the magnet bar 33. The iron plate 34 drives the end of the first insertion block 31 to disengage from the first slot 32, releasing the limitation on the position of the support column 4. The staff drives the support column 4 and the roller 5 to move downward relative to the mounting seat 2, so that the positioning block 28 disengages from the positioning groove 29, and then the removal of the support column 4 and the roller 5 can be completed, which is convenient for replacing the roller 5.
