A first protective sleeve 12 and a third protective sleeve 13 are coaxially fixed on the side of the front disk 4 close to the rear disk 5. The third protective sleeve 13 is located on the outside of the first protective sleeve 11, and a circular front slot 14 is provided on the side of the front disk 4 between the first and second protective sleeves. An annular rear slot 15 is provided at a position corresponding to the first protective sleeve 12 and the third protective sleeve 13 on one side of the rear disk 5 close to the front disk 4, and a second protective sleeve 16 is coaxially fixed at a position corresponding to the front slot 14 on one side of the rear disk 5 close to the front disk 4. The tail ends of the first protective sleeve 12 and the third protective sleeve 13 are inserted in the corresponding rear slot 15 to wrap the flange 3 on the inner side of the first protective sleeve 12, and the tail end of the second protective sleeve 16 is inserted in the corresponding front slot 14. A gas concentration sensor 17 is fixed on the inner side of the first protective sleeve 12, between the first protective sleeve 12 and the second protective sleeve 16, and between the second protective sleeve 16 and the third protective sleeve 13 on the front disk 4. A plurality of installation boxes 18 are fixedly arranged on one side edge of the front disk 4 close to the rear disk 5 and are evenly spaced at circumferential intervals. The installation box 18 is open at one end close to the rear disk 5 and a magnet 19 is fixedly arranged on the inner wall of the other end. A magnetic block 20 is fixedly arranged on the rear disk 5 corresponding to the installation box 18. The magnetic block 20 is inserted into the corresponding installation box 18 and is magnetically connected to the corresponding magnet 19. An electric push rod 21 is fixedly arranged on the outer side of the third protective cover 13 corresponding to the installation box 18. The telescopic end of the electric push rod 21 faces the corresponding installation box 18 and a through hole 22 is provided on the side of the corresponding installation box 18. A blind hole 23 is provided on the magnetic block 20 corresponding to the through hole 22. The telescopic end of the electric push rod 21 can be inserted into the corresponding blind hole 23 through the corresponding through hole 22. The gas concentration sensor 17, the electric push rod 21, the buzzer alarm 9, the wireless communication module 10 and the GPS locator 11 are all electrically connected to the controller 8.
[0020] When laying the gas pipeline, first connect the front gas pipeline 1 with the rear gas pipeline 2 through the flange 3, then move the front disk 4 on the front gas pipeline 1 to move it toward the side where the flange 3 is located until the first protective cover 12 is completely covered on the outside of the flange 3. Then, move the rear disk 5 to make it close to the front disk 4, and align the magnetic block 20 with the installation box 18 one by one until the magnetic block 20 is plugged into the corresponding installation box 18. At this time, the magnetic block 20 can be magnetically connected with the corresponding magnet 19, the first protective cover 12 and the third protective cover 13 are plugged into the corresponding rear slot 15, and the second protective cover 16 is plugged into the corresponding front slot 14.

In this way, the installation of the monitoring device at the flange connection can be completed. During the subsequent use, each gas concentration sensor 17 can monitor the gas concentration at the corresponding position in real time and feed it back to the controller 8. When a gas leak occurs at the flange connection, the leaked gas can first enter the inside of the first protective cover 12 and be blocked by the first protective cover 12 to prevent the gas from directly leaking and spreading to the external environment. It can also be monitored by the gas concentration sensor 17 inside the first protective cover 12 and fed back to the controller 8. The controller 8 can automatically control the start of the buzzer alarm 9 to give an alarm, control the start of the GPS locator 11 to provide positioning prompts, and feed back information to the remote terminal through the wireless communication module 10, so as to promptly remind the corresponding staff to find and solve the problem. If the first protective cover 12 fails to protect and the leaked gas continues to enter the inner side of the second protective cover 16, the second protective cover 16 can continue to block the gas leakage, and the gas concentration sensor 17 inside the second protective cover 16 can monitor and feedback to the controller 8. The controller 8 can automatically control and adjust the tone of the buzzer alarm 9 to increase the urgency of the warning, and transmit information to the remote terminal again through the wireless communication module 10, and remind the corresponding staff to rush to and deal with the leakage point. If the second protective cover 16 also fails to protect and the leaked gas continues to enter the inner side of the third protective cover 13, the third protective cover 13 can continue to block the gas leakage, and the gas concentration sensor 17 inside the third protective cover 13 can monitor and feedback to the controller 8. The controller 8 can automatically control and adjust the tone of the buzzer alarm 9 to increase the urgency of the warning, and transmit information to the remote terminal again through the wireless communication module 10, and remind the corresponding staff to rush to and deal with the leakage point. In this way, triple effective leakage monitoring and blocking of the flange connection of the gas pipeline can be achieved, and technical alarm positioning can be performed, which is more conducive to timely handling by the staff and has a higher safety level.When the monitoring device needs to be disassembled to deal with the leakage point or inspect the flange connection, it is only necessary to operate the electric push rod 21 to shrink and reset its telescopic end, so as to release the plug-in fixation of the magnetic block 20, and then pull the front disk 4 and the rear disk 5 to the left and right sides respectively to separate the magnetic block 20 from the magnet 19, until the magnetic block 20 is pulled out of the installation box 18, so that the front disk 4 and the rear disk 5 can be separated, and then the two disks are removed from the flange connection, so that the flange connection can be exposed for subsequent operations. In this way, the convenient docking assembly and disassembly and separation of the entire monitoring device can be realized, which is more flexible and practical. The opening and closing connection mode and specific structure of the box door 7 can all adopt the existing technology, and the gas concentration sensor 17, the electric push rod 21, the buzzer alarm 9, the wireless communication module 10, the GPS locator 11 and the controller 8 can all adopt the existing technology.
