[0030] The clamp mechanism is clamped on the outside of the pipe by means of a fixed clamp 1 and a movable clamp 2. At this time, the lugs 3 on one side of the fixed clamp 1 and the movable clamp 2 will fit together, and then the fixing bolts 4 are used to penetrate the lugs 3 for locking and fixing. Then the limit baffle 6 is rotated so that one side of the limit baffle 6 is inserted into the inner side of the limit slot 5. Finally, the limit baffle 6 is fixed by means of the buckle assembly 8 in the movable slot 7. At this time, the limit baffle 6 will be pressed and limited at the upper end of the fixing bolt 4 to prevent the fixing bolt 4 from loosening and falling off.
[0031] Preferably, a groove 11 is provided on the inner wall of the fixing clamp 1, a positioning hole 12 is provided on the surface of the groove 11, a contact switch 13 is installed inside the positioning hole 12, and an audible and visual alarm 14 is installed on one side of the outer end of the fixing clamp 1 (it can be a 12V audible and visual alarm 14 or other types of audible and visual alarm 14, which is not specifically limited in this application and can be set as needed).
[0032] When the fixed clamp 1 and the movable clamp 2 are clamped on the outside of the pipeline, the contact switch 13 in the groove 11 is not in contact with the outer wall of the pipeline, and a gap is left between the two. The contact switch 13 passes through the fixed clamp 1 through the positioning hole 12 and is electrically connected to the sound and light alarm 14. When the pipeline expands, the expanded protrusion will extend into the groove 11 and contact the contact switch 13. When the contact switch 13 is touched, the sound and light alarm 14 will be activated to sound an alarm, which is convenient for the staff to inspect and replace it in time to avoid the pipeline from bursting due to being in an expanded state for a long time.

At this time, the block 81 will move up and disengage from the limit hole 71, and the buffer spring 83 will also be squeezed and deformed. When the through hole 61 is aligned with the limit hole 71, the connecting plate 82 can be loosened to make the buffer spring 83 rebound the connecting plate 82 and the block 81, making it convenient for the block 81 to move down, pass through the limit hole 71 and be stuck in the through hole 61.

When the limit baffle 6 is rotated and plugged, the block 81 can be lifted up by the connecting plate 82, and the buffer spring 83 will be squeezed and deformed. When the limit baffle 6 is plugged into the inner side of the limit slot 5 so that the through hole 61 is aligned with the limit hole 71, the connecting plate 82 can be loosened to make the buffer spring 83 rebound the connecting plate 82 and the block 81, and finally the block 81 will move down through the limit hole 71 and be stuck in the through hole 61. At this time, the limit baffle 6 will be pressed and limited at the upper end of the fixing bolt 4. When the pipeline expands, the expanded protrusion will extend into the groove 11 and contact the contact switch 13. When the contact switch 13 is touched, the sound and light alarm 14 will be activated to sound an alarm, which is convenient for the staff to repair and replace in time.
