At the same time, the device is light and easy to carry;

[0025] The detection component 4 includes an annular detector 41 which is movably sleeved on the outside of the heating pipeline 1. The inner side of the annular detector 41 is slidably connected to the outer side of the heating pipeline 1. A groove 42 is provided at the inner end of the annular detector 41. A pressure sensing sheet 43 is provided inside the groove 42. The rear end of the pressure sensing sheet 43 is fixedly installed inside the groove 42, and the front end of the pressure sensing sheet 43 fits the outside of the heating pipeline 1. When the heating pipeline 1 is damaged, smoke will emerge from the damaged part and impact the pressure sensing sheet 43, thereby detecting the heating pipeline 1.

[0026] The driving assembly 2 includes a crab clip 21 movably arranged on the outside of the heating pipeline 1. The inside of the crab clip 21 is hollow to reduce the weight of the crab clip 21. Two crab clips 21 are arranged at the front and rear. An inclined block is arranged at the upper end of the crab clip 21. The bottom of the inclined block is clamped on both sides of the top of the heating pipeline 1 to fix the crab clip 21 on the outside of the heating pipeline 1. Rollers 22 are arranged on the adjacent side walls of the upper end of the crab clip 21. The rollers 22 are symmetrically arranged in two groups, each group of rollers 22 has two rollers, and one of the rollers 22 is arranged on the upper end of the crab clip 21. The side is fitted into the outer wall of the heating pipeline 1, and the roller 22 is rollingly connected to the outer wall of the heating pipeline 1. A rotating shaft 23 is arranged inside the roller 22. One end of the rotating shaft 23 extends through the interior of the crab clamp 21 and is connected to a motor 24. The motor 24 is fixedly installed inside the crab clamp 21.

[0030] Working principle: First, the motor 24 controls the rotation of the shaft 23 to drive the roller 22 to roll, thereby pulling the annular detector 41 to move. When damage is detected, the pressure sensing sheet 43 transmits information to the receiver 51. At this time, the warning light 52 on the receiver 51 lights up, and an alarm sounds through the alarm sounder 53. The device is small and light. While preventing heat loss from affecting sampling, it occupies a small space and is easy to carry.
