[0023] By installing the track 1 inside the gas pressure regulating cabinet, a predetermined running route can be made according to the position of each instrument to ensure that the monitoring camera 11 can accurately detect the instrument. At the same time, the monitoring camera 11 can be moved at different heights to facilitate the coverage of instruments located at different positions by the monitoring camera 11. The monitoring camera 11 can also be deflected at an angle to avoid some instruments that cannot be directly viewed by the monitoring camera 11 due to the installation angle, thereby ensuring that the monitoring camera 11 can clearly detect the data on the instruments.

[0024] The driving assembly 6 includes a driving motor 61 fixed to the bottom of the inner cavity of the movable box 2, the output shaft of the driving motor 61 is fixed with a driving pulley 62, the outer side of the rotating shaft 3 is fixed with a driven pulley 63, and the outer sides of the driving pulley 62 and the driven pulley 63 are connected by a linkage belt 64. The driving motor 61 drives the driving pulley 62 to rotate, and then the linkage belt 64 drives the driven pulley 63 to rotate, so as to drive the rotating shaft 3, so that the two sets of driving gears 4 drive the movable box 2 to move on the outside of the rack 5, so as to facilitate the transfer of the monitoring camera 11 according to a predetermined path.

[0025] A through hole is opened inside the support seat 10, and the inner cavity of the through hole is slidably connected to a limiting rod 13. One end of the limiting rod 13 is fixed to the bottom of the movable box 2, and the other end of the limiting rod 13 extends downward and is flush with the screw 8. Through the setting of the limiting rod 13, it is convenient to limit the support seat 10 to prevent the support seat 10 from rotating on the outside of the screw 8 with the threaded sleeve 9, resulting in the support seat 10 being unable to adjust the height up and down on the outside of the screw 8.

[0026] The adjustment component 12 includes a deflection motor 121 fixed to the top of the support base 10. A fan-shaped deflection slot 122 is opened inside the support base 10.

The two ends of the connecting rod 123 extend outward and are fixed with mounting rings 124. The monitoring camera 11 is installed on the outside of the mounting ring 124. The connecting rod 123 is driven to rotate in the deflection slot 122 by the deflection motor 121, and the mounting ring 124 is used to offset the monitoring angle of the monitoring camera 11 to ensure that the monitoring camera 11 takes into account different instruments.

[0027] Two sets of hangers 14 are fixed on the top of the movable box 2. The hangers 14 extend to the inner cavity of the track 1 and are slidably connected to the inner cavity of the track 1.

[0028] The track 1 includes a straight rail 101 and a curved rail 102, and the rack 5 is fixed in sections to the bottom of the straight rail 101 and the curved rail 102.

By setting the structure of the track 1, not only can the path of the track 1 be designed according to the pipeline distribution inside the gas pressure regulating cabinet, but also the hanger 14 can be conveniently disassembled and assembled from the track 1.

[0029] A groove is provided in the shape of a ring on the outer side of the support base 10, and the mounting ring 124 rotates in the inner cavity of the groove. The setting of the groove facilitates the storage of the mounting ring 124 and limits the shaking of the mounting ring 124, thereby preventing the surveillance camera 11 from shaking during deflection and affecting the detection accuracy.

[0030] During specific use, the track 1 is installed on the top of the inner cavity of the gas pressure regulating cabinet through the mounting plate 15, and then the driving motor 61 is started. The driving motor 61 drives the driving pulley 62 to rotate, and then the driving pulley 62 drives the driven pulley 63 to rotate through the linkage belt 64, driving the rotating shaft 3 and the driving gear 4. Subsequently, the driving gear 4 drives the movable box 2 to move on the outside of the rack 5, and the rotating motor 7 drives the screw 8 to rotate. The threaded sleeve 9 drives the support seat 10 to adjust the height with the cooperation of the limit rod 13, and then the deflection motor 121 deflects the monitoring angle of the monitoring camera 11 through the connecting rod 123 and the mounting ring 124, so as to facilitate the detection of instruments and equipment at different positions inside the gas pressure regulating cabinet and ensure the safety of the gas pipeline.
