[0026] The lower ring piece 41 and the upper ring piece 42 cooperate with the two sets of lower fixing rings 43 and upper fixing rings 44 to tightly clamp the gas pipeline, significantly enhancing the stability of the entire device and preventing loosening or displacement due to vibration or external force.

[0027] Two groups of first mounting holes 6 are respectively defined on the outer sides of the two groups of upper fixing rings 44 , and two groups of second mounting holes 7 are respectively defined on the outer sides of the two groups of lower fixing rings 43 .

[0028] The provision of the first mounting hole 6 and the second mounting hole 7 provides clear positioning points for the installation and fixation of the fixing assembly 4. The use of appropriate fasteners such as bolts, nuts, etc. for fixation can significantly enhance the structural strength of the entire device.

[0029] Two sets of sealing strips 8 are installed on the top of the lower ring piece 41 , and the bottom of the upper ring piece 42 is in contact with the top of the sealing strips 8 .

[0030] By setting the sealing strip 8, when the upper ring piece 42 and the lower ring piece 41 are closed, the sealing strip 8 will fit with the bottom of the upper ring piece 42 to form a sealing barrier, which helps prevent gas from leaking from the gap between the fixed component 4 and the gas pipeline.

[0031] A detection rod 9 is provided on the top of the detection device 1 , and through holes 10 for use by the detection rod 9 are respectively opened on the opposite sides of the connecting plate 3 and the lower ring plate 41 .

The display screen 14 can intuitively display the detected information, so that relevant personnel can judge the situation more accurately and formulate effective response measures.

[0037] The working principle of the present utility model is as follows: when in use, a suitable fixing assembly 4 is selected according to the diameter of the gas pipeline to be detected. After the selection is completed, the limit plate 54 is aligned with the through groove 55 and removed into the fixing seat 2, and the threaded rod 52 is rotated. The threaded rod 52 drives the positioning rod 53 to move and insert into the positioning hole 56 to achieve a stable connection between the connecting plate 3 and the fixing seat 2. Then the lower circle piece 41 and the upper circle piece 42 are respectively fixed to the outside of the gas pipeline. The lower fixing ring 43 and the upper fixing ring 44 are respectively provided with a first mounting hole 6 and a second mounting hole 7. These can be used to install bolts or other fasteners to fasten the fixing assembly 4 to the gas pipeline.

The connecting plate 3 and the lower circle piece 41 are provided with a through hole 10 for the detection rod 9 to pass through and extend into the vicinity of the gas pipeline for detection. When the detection rod 9 detects a gas leak, it will transmit a signal back to the detection device 1, the alarm 13 will sound an alarm, and the display screen 14 will display the leakage information.
