[0034] The following reference Figures 1 to 4 This application describes a pressure pipeline deformation detection device according to some embodiments.

[0035] See Figures 1 to 4 As shown, an embodiment of this application provides a pressure pipeline deformation detection device, including: a mobile vehicle body 1, a first detection component 2, and a second detection component 3; wherein, along the moving direction of the mobile vehicle body 1 in the pressure pipeline, the first detection component 2 and the second detection component 3 are respectively disposed at both ends of the mobile vehicle body 1.

[0036] The first detection component 2 includes a support member 21, a displacement sensor 22, a detection component 23, and a spring. The support member 21 is disposed on the moving vehicle body 1, the displacement sensor 22 is disposed on the support member 21, and the detection component 23 is slidably connected to the detection end of the displacement sensor 22. The detection component 23 is used to contact the inner wall of the pressure pipeline, and the displacement sensor 22 is used to detect the moving distance of the detection component 23. Along the moving direction of the detection component 23, the spring is disposed between the detection component 23 and the detection end of the displacement sensor 22 to maintain the contact between the detection component 23 and the inner wall of the pressure pipeline.

[0037] The second detection component 3 includes a pull-rope encoder 31 and a limiting member 32. The pull-rope encoder 31 is mounted on the moving vehicle body 1, and one end of the pull-rope encoder 31 is connected to the limiting member 32. The limiting member 32 is used to fix the limiting member 32 at one end of the pressure pipe. The pull-rope encoder 31 is used to detect the position of the moving vehicle body 1 inside the pressure pipe.

[0038] In this embodiment, the pressure pipeline deformation detection device is used as follows: First, the moving vehicle 1 is placed inside the pressure pipeline, and the limiting member 32 is fixed to the open end of the pressure pipeline. Then, the moving vehicle 1 is moved inside the pressure pipeline, which will synchronously drive the first detection component 2 to move. When the first detection component 2 moves forward, its detection component 23 will move adaptively under the action of the spring due to the deformation inside the pressure pipeline. The corresponding displacement sensor 22 measures the moving distance of the detection component 23, which can accurately measure the deformation state of the pressure pipeline, thus improving the accuracy of the device in measuring the deformation inside the pressure pipeline. Moreover, in the above process, the position of the moving vehicle 1 can be detected in real time using the pull rope encoder 31, thereby locating the deformation position inside the pressure pipeline.

[0039] As can be seen, this embodiment provides a device for conveniently detecting the deformation of the inner wall of a pressure pipeline. It is simple, convenient, time-saving, and labor-saving to operate.

[0057] The spring is sleeved on the connecting part 232 and is located between the detection part 231 and the detection end of the displacement sensor 22 along the moving direction of the detection member 23.

[0058] In this embodiment, the detection component 23 is always in contact with the inner wall of the pressure pipe under the action of the spring, and can be effectively detected regardless of whether the inner wall of the actual pressure pipe is concave or convex.

[0065] It is worth noting that the controller 6, displacement sensor 22 and rope encoder 31 mentioned above are all existing devices.
