[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention can cause the movable ring to move upward by contracting the locking rod, thereby causing the upper locking main rod and the upper locking auxiliary rod to open, so that the upper locking auxiliary rod can be closely attached to the upper end of the ceiling. Further, due to the contraction of the locking rod, the sealing ring can be deformed, so that the sealing ring is closely attached to the drilled hole, and further the lower locking main rod is closely attached to the bottom surface of the ceiling, thereby ensuring the stability of the monitoring panel. In addition, if the thickness of the top wall is relatively large, when the locking rod is contracted, the upper locking main rod and the upper locking auxiliary rod are opened, so that they are clamped in the hole inside the top wall. Further contraction of the locking rod can cause the sealing ring to be closely attached to the drilled hole in the top wall, and at the same time cause the lower locking main rod to be closely attached to the lower surface of the top wall, thereby ensuring the stability of the monitoring panel. At the same time, the device can be adapted to top walls of different thicknesses, thereby increasing the use range of the entire device.

[0017] (2) The present invention can move the moving wheel by extending the proximity rod, so that multiple moving wheels can be closely attached to the gas pipe, thereby ensuring the stability of the detection main ring and the detection secondary ring, and can adapt to gas pipes of different sizes, thereby increasing the use range of the device. At the same time, the device can change the direction of the moving wheel through multiple moving wheel reversing motors, so that the moving wheel can move horizontally and vertically along the gas pipe at the same time, so that any position of the gas pipe can be detected, thereby ensuring the detection accuracy and improving the detection efficiency;

[0018] (3) The present invention surrounds the outside of the gas pipeline with multiple ring sensors, which can conveniently detect whether there is a gas leak outside the gas pipeline, thereby ensuring the accuracy of the detection and improving the detection efficiency. At the same time, since the marking rod is extended, the inner sensor can be close to the gas pipeline, so that the specific location of the gas leakage area outside the gas pipeline can be detected, thereby further ensuring the detection accuracy and thus ensuring the detection effect;

[0019] (4) The marking solenoid valve and the marking pump of the present invention can cooperate to pump the marking liquid in the marking liquid tank into the marking ring through the marking liquid delivery pipe, and then spray it out through the nozzle, so as to achieve the purpose of marking. At the same time, the charging rod of the device can be retracted, so as to drive the lock support plate to move up and down, so that the whole device can be adapted to the gas delivery pipes at different distances from the top wall, thereby improving the use range of the whole device;

[0020] (5) The present invention can reverse the direction of the monitoring plate by cooperating with the monitoring motor and the reversing motor, so that the monitoring sensor can monitor any position of the top wall or the bottom, thereby ensuring the accuracy of monitoring. At the same time, the cleaning motor can drive the cleaning main gear to rotate, and then drive the cleaning sub-gear to rotate while revolving around the cleaning main gear, so that any position of the filter plate can be cleaned. At the same time, the device can measure the distance between the monitoring plate and the support plate by a measuring ruler, so that different numbers of monitoring sensors can be set according to the monitoring range, thereby improving the sensitivity and accuracy of monitoring, and being able to fully cover a larger monitoring area, so that gas leaks can be detected more quickly and accurately, thereby ensuring monitoring accuracy.

When the monitoring sensor 316 detects that there is a gas leak in the area, the controller 404 alarms, and further the controller 404 controls the charging plate 402 to open. At this time, the controller 404 controls the moving wheel reversing motor 501 and the moving motor 504 to make the detection main ring 2 move along the gas pipeline 1 to the gas leakage area. Further, due to the multiple sensors 203 in the ring, the gas pipeline 1 on the same plane can be detected. In the case of gas leakage, when one of the ring inner sensors 203 detects a gas leakage at the location, the controller 404 controls the mobile motor 504 to stop working. At this time, the controller 404 controls the two marking wheel motors 905 to work, thereby driving the two marking wheels 903 to rotate, thereby driving the mobile arc plate 9 to slide along the moving rail 204, so that the inner sensor 912 moves to the gas leakage location. Further, the controller 404 controls the marking rod 902 to extend, thereby driving the inner sensor 912 to move inward, so that the leakage point can be accurately detected. At this time, the controller 404 controls the marking pump 907 and the marking solenoid valve 908 to work.Thus, the marking liquid in the marking liquid tank 906 is transported to the inside of the marking ring 910 through the marking liquid delivery pipe 909, and then sprayed out through the spray head 911, thereby achieving the purpose of marking.
