[0002] Early heating pipelines mostly used simple metal pipes, such as cast iron pipes and steel pipes, primarily for small, localized heating systems. With the expansion of cities and the increase in demand for centralized heating, the diameter of heating pipelines has gradually increased, and their length has been continuously extended, forming more complex pipe network systems. According to publication number CN209470036U, a heating pipeline leakage alarm device is disclosed, including a positioning rod, a groove on the side wall of the positioning rod, a working chamber fixed to the upper end of the positioning rod, and an alarm system located within the working chamber. A thermistor is connected to the alarm system. There are two grooves, one housing a thermistor and the other a resistive humidity sensor. A protective mesh is fixed to the inner wall of the groove. The positioning rod, from top to bottom, has a positioning ring, a positioning nut, and a protective sleeve. This invention is used for leak detection in heating pipelines. It can be installed on the pipeline at any location where a leak may occur to detect the pipeline. When a leak occurs, it can quickly send an alarm signal to the host computer. However, existing devices cannot accurately detect pipelines after production. They can only detect whether a single pipeline is leaking. Furthermore, existing detection devices are fixed installations and cannot detect leaks from mobile detectors.

Then, move the fixing frame 211 to the side of the heating pipeline through the moving wheel 212 at the bottom in the moving groove 11. Then, rotate the screw 215 to push the moving clamp 214 to clamp and limit the heating pipeline. Then, pull the mounting cover 223 to flip it over and cover the other end of the heating pipeline. Then, turn on the power to start the air inflation pump 221 to supply air into the heating pipeline through the air supply pipe 22. At the same time, start the servo motor 322 to drive the top conveyor belt group 323 to rotate. The rotation of the conveyor belt group 323 can drive the moving block 324 and the ring plate 41 to move. The movement of the ring plate 41 can drive the temperature alarm 415 installed at the top to move outside the heating pipeline. When the heating pipeline is leaking air, the gas can pass through the central ring groove 411 and then blow upward into the through-hole 413 to the temperature alarm 415 for detection. This is the complete working principle of this utility model.
