[0027] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes: a marking component arranged on the mounting frame 11, the marking component is used to mark the leakage position on the pipeline 01, and a group of marking components are arranged on the upper and lower mounting frames 11, and the marking components include: the guide rail 41 fixedly installed on the mounting frame 11, and the guide rails 41 of the two groups of marking components are circled outside the pipeline 01 together; the moving block 42 slidably installed on the guide rail 41; the electric wheel 43 rotatably installed on the moving block 42, and the electric wheel 43 rolls in contact with the guide rail 41 to control the moving block 42 to move on the guide rail 41; the electric push rod 44 fixedly installed on the moving block 42 ; the motor C45 fixedly mounted on the telescopic end of the electric push rod 44; the cross bar 46 fixedly mounted on the output end of the motor C45; the marking pen 47 slidably mounted on the end of the cross bar 46; the elastic member 48 fixedly mounted between the marking pen 47 and the cross bar 46, the elastic member 48 is a compression spring; the fixing member B49 arranged on the cross bar 46, the cross bar 46 is divided into two, the fixing member B49 is a combination of a sleeve frame and an adjusting bolt, after changing the distance between the two parts of the cross bar 46, the sleeve frame and the cross bar 46 are compressed using the adjusting bolt, so that the cross bar 46 can be adjusted and fixed after adjustment.
[0028] like Figure 1 and Figure 7As shown, it also includes: the blower 51 fixedly installed on the upper and lower layers of the mounting frame 11, the blower 51 is used to blow away impurities on the pipeline 01, so that the marking pen 47 can mark smoothly to prevent impurities from affecting the marking effect.
[0029] Before using the monitoring device, adjust the distance between the two layers of the installation frames 13 according to the size of the pipeline 01. Assuming that the pipeline 01 to be monitored at this time is a pipeline 01 of a larger size, operate the motor A21 to control the upper rotating arm 15 to rotate upward and the lower rotating arm 15 to rotate downward, thereby controlling the two layers of the installation frames 13 to separate from each other, thereby achieving the purpose of expanding the range of the total frame, and unlocking the fixing piece B49, and adjusting the size of the marking range of the marking pen 47 by adjusting the length of the cross bar 46; after completion, remove the upper layer of the installation frame 11 from the upper layer of the installation frame 13 Remove it from the upper layer, unfasten the fixing piece A16, separate the upper installation frame 13, and disassemble the overall frame from a ring-like shape into a linear shape. At this time, the monitoring device can be circled around the outside of the pipeline 01, and the magnetic wheel 33 is magnetically fixed to the outside of the pipeline 01, so that the cross frame 14 and the rotating arm 15 slide relative to the installation frame 13, that is, the monitoring device adapts itself according to the size of the pipeline 01. Finally, use the fixing piece A16 to fix the upper installation frame 13, and install the upper installation frame 11 back on the upper installation frame 13, thus completing the preparatory work of the monitoring device before monitoring.
[0030] Afterwards, the hub motor 32 is started to drive the monitoring device to move forward along the pipeline 01. Since the pipeline 01 is generally assembled using a flange, and the diameter of the flange is larger than the pipeline 01, the monitoring device automatically overcomes obstacles by setting a traveling component. When moving to the flange, the motor B35 controls the mounting block 31 to be retracted toward the horizontal frame 14, so that the magnetic wheel 33 bypasses the flange. In particular, when each group of traveling components overcomes obstacles in turn, among the three groups of traveling components on the same side, no matter which group overcomes the obstacle, the other two groups remain connected to the pipeline 01, thereby ensuring that the monitoring device can have stable support.
[0031] When the monitor 12 detects that the local natural gas concentration of the pipeline 01 increases, it can be determined that there is a natural gas leak in the pipeline 01. First, the blower 51 on the corresponding position side is started to blow away impurities on the pipeline 01 within the range, and then the marking component on the corresponding position side is operated, and the electric wheel 43 rotates to move the moving block 42 to the position of the natural gas leak. The electric push rod 44 extends to press the marking pen 47 against the pipeline 01, and the elastic member 48 is stretched. Then, the motor C45 runs to control the cross bar 46 to rotate one circle, so that the marking pen 47 draws a circle on the pipeline 01, so that the leakage position can be quickly found during subsequent maintenance. The elastic member 48 keeps the marking pen 47 in contact with the pipeline 01 at all times to ensure the marking effect.
[0032] After the monitoring operation is completed, the upper mounting frame 11 is removed, and the fixing member A16 is released, and the monitoring device can be removed from the pipeline 01.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
