[0002] Existing heating pipes will continue to leak due to aging of the pipe material and working environment, which will have a great impact on the stable and safe operation of the heating system.

[0003] The Chinese utility model with the current announcement number: CN221121452U discloses a device for finding and plugging leaks in a heating pipeline. It includes a shell, multiple support blocks are fixedly connected at both ends of the shell, a mobile component is movably connected inside the support block, multiple mobile components are movably connected to the outer wall of the pipeline, and a rotating component is movably connected inside the shell; multiple clamping components are fixedly connected inside the rotating component, the inner wall of the clamping component is movably connected to the outer wall of the pipeline, and a plugging component is fixedly connected inside the rotating component. The utility model is implemented by sleeves of multiple clamping components on the outer wall of the pipeline, so that the clamping components fix the rotating component and the shell on the outer wall of the pipeline, and the shell is driven to move by the moving component, thereby driving the rotating component and the plugging component to move on the outer wall of the pipeline, adjusting the direction of the plugging component by the rotation of the rotating component, and plugging the damaged part of the pipeline by the plugging component.

[0004] The existing method of using satellite remote sensing to locate the leakage position of the heating pipeline is that the range that the satellite can locate is relatively large. Therefore, when detecting the actual pipeline leakage point, the staff still needs to use thermal imaging instruments to conduct further detailed detection within the approximate range of the pipeline located by the satellite, so as to determine the specific location of the pipeline leakage and repair it. The actual operation is labor-intensive and the manual detection efficiency is low, which is not convenient for actual use. Utility Model Content

[0005] The purpose of the utility model is to provide a heating pipe leakage rapid positioning device using satellite remote sensing for existing devices, which has the advantages of improving the efficiency of heating pipe leakage point detection and facilitating installation on a variety of heating pipes with different diameters for detection.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a heating pipeline leakage rapid positioning device using satellite remote sensing, comprising a first arc-shaped collar and a second arc-shaped collar, the first arc-shaped collar and the second arc-shaped collar are hinged to each other, the ends of the first arc-shaped collar and the second arc-shaped collar away from each other are fixedly connected with connecting bolts bolted to each other, the tops of the first arc-shaped collar and the second arc-shaped collar are bolted with detection components, the tops of the first arc-shaped collar and the second arc-shaped collar are slidably connected with telescopic cylinders on both sides, the first arc-shaped collar and the second arc-shaped collar are welded with positioning rods slidably plugged with the telescopic cylinder on both sides of the inside, the surface of the positioning rod is fixedly sleeved with a spring fixedly connected with the telescopic cylinder, the end of the telescopic cylinder away from the spring is rotatably connected with a rotating shaft, the two ends of the rotating shaft are fixedly sleeved with rollers, the inside of the end of the telescopic cylinder away from the spring is bolted with a motor, the output end of the motor is fixedly connected with a first bevel gear, and the surface of the rotating shaft is fixedly sleeved with a second bevel gear meshing with the first bevel gear.

[0007] The above technical solution is adopted: by fixing the first arc-shaped collar and the second arc-shaped collar on the surface of the heating pipe, and then driving the roller to rotate on the surface of the heating pipe by a motor, so that the first arc-shaped collar and the second arc-shaped collar can drive the detection component on the surface of the heating pipe to automatically move and detect the leakage position. This not only reduces the labor intensity of the staff, but also improves the detection efficiency. By using the elastic force of the spring to drive the telescopic cylinder to slide inside the first arc-shaped collar and the second arc-shaped collar, the telescopic cylinder can push the roller to expand and contract according to the diameter change of the heating pipe, so that the roller can stably fit on the surface of the heating pipe to drive the first arc-shaped collar and the second arc-shaped collar to move. Therefore, the device can be applied to a variety of heating pipes with different diameters for detection, thereby improving the practicality of the device.

[0008] The utility model is further configured such that a satellite antenna is fixedly installed on one side of the top of the detection component, a signal transceiver module, a satellite communication auxiliary module and a data microprocessor module used in conjunction with the satellite antenna are bolted to the inside of the detection component, a thermal imaging sensor is bolted to the bottom of the detection component, a thermal imaging detection probe is fixedly connected to the bottom of the thermal imaging sensor, and a rechargeable battery pack electrically connected to the thermal imaging sensor, the signal transceiver module, the satellite communication auxiliary module and the data microprocessor module is also fixedly installed inside the detection component.

[0009] The above technical solution is adopted: by installing the device on the pipeline, and then using satellite remote sensing to detect the approximate range of the heating pipeline leakage, and receiving satellite signals through the satellite antenna. After that, the ground personnel use the satellite communication auxiliary module and the data microprocessing module to process the data to know the approximate range of the heating pipeline leakage, and then the control device moves to the range of the pipeline. Then, the thermal imaging detection probe and thermal imaging sensor are used to detect the movement of the pipeline at this end, and data imaging is performed. The signal transceiver module and the satellite antenna are used to send the imaged data to the ground detection station, so that the staff can observe the surface of the pipeline. In the thermal imaging picture, the location of the pipeline leakage will be hotter than other locations due to the overflow of internal hot air, so the staff can use the abnormal position with higher temperature in the thermal imaging picture to determine the pipeline leakage point. Finally, after finding the specific leakage point of the worker's pipeline, the maintenance personnel can be dispatched to this point to directly repair it.

[0010] The utility model is further configured such that the tops of the first arc-shaped collar and the second arc-shaped collar are both bolted with signal lights electrically connected to the rechargeable battery pack.

[0011] The above technical solution is adopted: by setting a signal light, it is easy to observe whether the module inside the detection component is damaged, so as to facilitate timely maintenance.

[0012] The utility model is further configured such that one side of the top of the first arc-shaped collar and the second arc-shaped collar is bolted with an inspection door used in conjunction with the detection component, and a heat dissipation mesh hole is provided on the front side of the inspection door.

[0013] By adopting the above technical solution, the inspection door can be removed to facilitate the repair and replacement of the modules inside the detection component, and the heat dissipation mesh can be used to ventilate and dissipate heat for the detection component.

[0014] The utility model is further configured that a non-slip sleeve is fixedly sleeved on the surface of the roller.

[0015] The above technical solution is adopted to improve the surface friction, thereby preventing slipping on the pipeline surface and improving the movement stability.

[0017] By adopting the above technical solution, the motor can be ventilated and cooled, thereby improving working stability.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] The utility model fixes the first arc-shaped collar and the second arc-shaped collar on the surface of the heating pipe, and then drives the roller to rotate on the surface of the heating pipe through a motor, so that the first arc-shaped collar and the second arc-shaped collar can drive the detection component on the surface of the heating pipe to automatically move and detect the leakage position. This not only reduces the labor intensity of the staff, but also improves the detection efficiency;

[0020] The utility model utilizes the elastic force of the spring to drive the telescopic cylinder to slide inside the first arc-shaped collar and the second arc-shaped collar, so that the telescopic cylinder can push the roller to expand and contract according to the diameter change of the heating pipe, so that the roller can stably fit on the surface of the heating pipe to drive the first arc-shaped collar and the second arc-shaped collar to move.
