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

[0016] (1) The present invention can move the movable ring 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 large, when the locking rod is contracted, the upper locking main rod and the upper locking auxiliary rod are opened, thereby being 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, while causing 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 range of use of the entire device.

[0017] (2) The present invention can move the moving wheel by extending and retracting the close 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 scope of use of the device. At the same time, the device can reverse 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 detection accuracy and improving detection efficiency;

[0018] (3) The present invention surrounds the outside of the gas pipeline with multiple ring sensors, which can easily 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 cooperate to pump the marking liquid inside the marking liquid tank into the marking ring through the marking liquid delivery pipe, and then spray it out through the nozzle, thereby achieving the purpose of marking. At the same time, the charging rod of the device is retractable, thereby driving the lock support plate to move up and down, so that the entire device can adapt to gas pipes at different distances from the top wall, thereby improving the use range of the entire 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 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 the accuracy of monitoring.
