Technical Field

[0001] The utility model relates to the technical field of heating pipe network detection devices, and more specifically, to a leakage positioning detection device for heating pipe networks. Background Technique

[0002] Due to the cold in the north in winter, heating is mostly required, and many heating pipe networks will be used. If the heating pipe network leaks, it will affect heating and waste energy. Therefore, it is necessary to check the heating pipe network regularly or irregularly.

[0003] According to a leakage positioning detection device for heating pipe networks disclosed in Chinese Patent CN202220303336.5, this application includes a frame. Two support shafts are rotatably connected inside the frame. Traveling rollers for walking outside the pipe are respectively fixed to the outer parts of the two support shafts. A servo electric cylinder is fixed to the frame. A fixed rod is fixed to the end of the output shaft of the servo electric cylinder. The end of the fixed rod is detachably connected to a fixing plate. A smoke sensor, a temperature sensor, a PLC controller and an alarm are fixed to the fixing plate. Auxiliary stability structures are respectively arranged on both sides of the frame. A power assembly for driving the traveling rollers to rotate is arranged on the frame. The leakage positioning detection device for heating pipe networks can walk outside the pipe and can monitor the leakage of the heating pipe network, with high automation and improved monitoring efficiency. When the existing leakage positioning detection device for heating pipe networks moves on the outer wall of the pipe, it lacks an anti-detachment structure.

The driving roller 6 drives the driving box 2 to move on the heating pipe 3, and the driving box 2 drives the detection box 1 to move. At this time, the smoke sensor 10 and the temperature sensor 11 in the detection box 1 detect the outer wall of the heating pipe 3. By setting the driving roller 6, the driving box 2 can move on the pipeline by itself, making the detection more time - saving and labor - saving; When installing the anti - detachment cover 7, first, the operator rotates the runner 24 to drive the lead screw 16 to rotate. The lead screw 16 drives the moving sleeve 17 to move downward. The moving sleeve 17 drives the conical pressing block 18 to move downward. At this time, the conical pressing block 18 leaves the ball 22, and the spring 21 resets to drive the limiting rod 19 to move into the positioning column 13, so that the end of the limiting rod 19 away from the ball 22 moves into the sliding hole. At this time, the positioning column 13 on the anti - detachment cover 7 is inserted into the positioning groove 14 at the bottom end of the driving box 2. Subsequently, rotate the runner 24 in the reverse direction to drive the lead screw 16 to rotate. The lead screw 16 drives the conical pressing block 18 to move upward through the moving sleeve 17. The conical pressing block 18 squeezes the two groups of balls 22, and the balls 22 drive the limiting rod 19 to move outward from the positioning column 13 until it is inserted into the limiting groove 23 on the driving box to limit it. By setting the anti - detachment cover and the connection component, when the detection device moves and detects on the heating pipe, it can prevent it from slipping off the heating pipe under the influence of the external environment, improve its safety, and make its movement more stable. Among them, the connection component is convenient for disassembling and assembling between the anti - detachment cover and the driving box, saving the disassembly and assembly time between the detection device and the pipeline.
