However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

A pressure detection part and a leakage detection part are installed between the inner detection part 8 and the outer detection part 6, and the inner side of the inner detection part 8 is in contact with the outer periphery of the pipeline to be tested.
[0030] like Figure 4 As shown, the pressure detecting member includes a pressing member 10 and a fixing member 12. The pressing member 10 is installed on the outer periphery of the inner detecting member 8, and the fixing member 12 is installed on the inner side of the outer detecting member 6. A cavity 1 is opened in the fixing member 12, and a pressure sensor 11 is installed at the bottom of the cavity 1. The end of the pressing member 10 passes through the bottom surface of the fixing member 12, and the end of the pressing member 10 is located in the cavity 1.
[0031] like Figure 1-Figure 3 As shown, the leakage detection component includes a plurality of airbags 5, and the plurality of airbags 5 are all installed on the outer periphery of an outer detection component 6, a groove 1 is provided at a position corresponding to the outer detection component 6 and the airbag 5, an air guide tube 9 passes through the bottom surface of the groove 1, an end of the air guide tube 9 is installed on the outer periphery of an inner detection component 8, a through hole 1 is provided at a position corresponding to the inner detection component 8 and the air guide tube 9, and the through hole 1 is connected to the airbag 5 through the air guide tube 9 and the groove 1 in sequence.
[0032] like Figure 1-Figure 3 As shown, the two moving mechanisms both include a servo motor 2 and a screw 7. The servo motor 2 is installed on the side of the base 1. The screw 7 passes through the base 1. The output end of the servo motor 2 is detachably connected to the end of the screw 7. Two opposite threads are provided on the screw 7. The connecting piece 1 3 and the connecting piece 2 4 are respectively matched with the two opposite threads.

[0034] In the present invention, the pressure sensor 11 is externally connected to a controller, and the controller is communicatively connected to a buzzer.
[0035] In the present invention, the inner detection member 8 of the left detection assembly and the inner detection member 8 of the right detection assembly are both arc-shaped and arranged relatively, and the pipeline to be tested is located between the inner detection member 8 of the left detection assembly and the inner detection member 8 of the right detection assembly.

[0039] The working principle of the utility model for detecting the pressure in a pipeline is as follows: when the pressure in the pipeline to be tested is high, the pipe wall of the pipeline to be tested expands outward, causing the pressure piece 10 to move toward the bottom of the cavity of the fixing piece 12, and the low-pressure piece 10 squeezes the pressure sensor 11. The pressure sensor 11 transmits a signal to the controller, and the controller controls the operation of the buzzer to remind the detection personnel. In the process of the movement of the pressure piece 10, due to the outward expansion of the pipe wall, the air guide tube 9 moves in the direction close to the airbag 5.
