[0036] Reference Figure 2 , Figure 3 and Figure 6 The inner wall of the connecting sleeve 4 is provided with an installation component, which includes a fixed cylinder 71 for improving the sliding stability of the installation component. The rear side of the fixed cylinder 71 is fixedly connected to the inner wall of the front end of the connecting sleeve 4. The inner wall of the front end of the fixed cylinder 71 is slidably connected with a pull rod 72. The limit of the connecting rod 3 is released by pulling the pull rod 72. The rear side of the pull rod 72 is fixedly connected with a clamping block 74. The clamping block 74 is limited by sliding on the inner wall of the clamping groove 75. The outer wall of the clamping block 74 slides in the connecting sleeve 4. The pull rod 72 and the fixed cylinder 71 are elastically connected by a return spring 73. The elastic force of the return spring 73 improves the stability of the block 74 and can quickly release the limit on the connecting rod 3.

The right side of the connecting rod 3 rotates and slides on the inner wall of the left side of the connecting sleeve 4.

[0037] Working principle: During use, when the device needs to be installed on the pipeline, first insert the connecting rod 3 on the mounting plate 1 into the inner wall of the connecting sleeve 4 on the adjacent group of mounting plates 2, and pull the pull rod 72 while inserting it, driving the block 74 to slide and squeezing the reset spring 73 at the same time. At this time, the connecting rod 3 is completely inserted into the inner wall of the connecting sleeve 4, and the pull rod 72 is released. The elastic force of the reset spring 73 drives the pull rod 72 back to its position, thereby driving the block 74 to slide into the inner wall of the slot 75 to limit the connecting rod 3. Multiple groups of mounting plates 1 and 2 are installed. At this time, they are placed on the outer wall of the pipeline, and then the connecting rod 3 on another group of mounting plates 1 and 2 is inserted into the connecting sleeve 4 of the adjacent group for installation, so that the device forms a closed loop.

[0038] During installation, the two groups of limit blocks 53 can be pulled to squeeze the compression spring 54, so that the limit blocks 53 slide out from the inner wall of the limit groove 52, and the mounting plate 1 and the mounting plate 2 can be pulled to make the expansion plate 51 slide out from the inner wall of the mounting plate 1, and the distance between the mounting plate 1 and the mounting plate 2 can be adjusted. When the distance is appropriate, the two groups of limit blocks 53 are released, and the elastic force of the compression spring 54 drives the two groups of limit blocks 53 to slide into the corresponding slots on the limit groove 52, thereby limiting the expansion plate 51, so that the device has a certain adjustment ability, thereby improving the applicability of the device.

[0039] During installation, multiple groups of mounting plates 1 and 2 are in contact with the outer wall of the pipe, so that multiple groups of sensor bodies 64 are in contact with the outer wall of the pipe. At the same time, the elastic tensile force of the tension spring 63 drives the slide bar 61 to move toward the outside of the mounting plates 1 and 2, driving the fixed plate 62 to squeeze the sensor body 64, so that the sensor body 64 is tightly attached to the outer wall of the pipe, thereby improving the accuracy of detection and the stability of the device.
