[0044] Specifically, the model of the air pressure sensor 12 is VTI-SCP1000, and its working principle is that the main sensing element of the air pressure sensor is a pressure-sensitive film, which is connected to a flexible resistor. When the pressure of the measured gas decreases or increases, the film deforms, and the resistance value of the resistor will change. The resistance value of the resistor changes. The corresponding principle structure is not drawn in the attached figure.

[0048] In a more specific embodiment, a first connecting flange 13 is provided at one end of the RTP pipe body 11, and second connecting flanges 26 matching the first connecting flange 13 are provided at both ends of the connecting pipe 21 and fixed by bolts. By disassembling and assembling the first connecting flange 13 and the second connecting flange 26, the convenience of disassembling and assembling the barrier assembly 2 is increased.

[0049] In a more specific embodiment, a buzzer 28 is provided on the outside of the shell 22, and alarm lights 29 are provided on both sides of the shell 22. When the air pressure sensor 12 on the outside of the RTP tube body 11 detects that the gas inside the section of the RTP tube body 11 is leaking, the buzzer 28 and the alarm light 29 are used to remind nearby maintenance personnel, so that the maintenance personnel can check and repair the RTP tube body 11 in time.

[0050] In a more specific embodiment, the fixing member 33 includes: a lower fixing sleeve 331 is arranged on the

[0051] The top of the support plate 32; the rotating shaft 332 is arranged at the top of the lower fixed sleeve 331; the upper fixed sleeve 333 is arranged on the outside of the rotating shaft 332, the RTP tube body 11 is placed in the lower fixed sleeve 331, and the upper fixed sleeve 333 is closed by rotating the rotating shaft 332, so as to clamp and fix the RTP tube body 11.
