[0005] Using the above two methods, it is impossible to monitor the displacement of the underground heating pipes. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a device that can monitor the displacement of underground heating pipes, thereby improving the accuracy of early warning.

[0007] The present invention adopts the following technical solution:

[0008] The present invention is used to monitor the underground heating pipe 1 and the underground pipe well, and includes a compensator displacement monitoring module, a water level measurement module, a temperature measurement module, a pressure measurement module, a gas detection module and a host computer. The compensator displacement monitoring module, the water level measurement module, the temperature measurement module, the pressure measurement module and the gas detection module are all connected to the host computer through an RS485 interface.

[0009] The compensator displacement monitoring module described in the present invention includes a connecting frame 2 fixedly connected to one end of a heating underground pipe 1, a supporting tube 3 arranged on the connecting frame 2, a rotating shaft 4 passing through the upper end of the supporting tube 3, a wire pull turntable 5 fixedly arranged on the rotating shaft 4, an infrared receiving board fixedly arranged on the rotating shaft 4, an infrared transmitting board 6 arranged on the connecting frame 2 and a microprocessor, one end of the rotating shaft 4 is located in the supporting tube 3, a torsion spring 7 for providing a pre-tightening force to the rotating shaft 4 is arranged in the supporting tube 3, the infrared receiving board is located between the supporting tube 3 and the wire pull turntable 5, the infrared transmitting board 6 is located at the edge of the infrared receiving board and partially overlaps with the infrared receiving board, a wire is arranged on the wire pull turntable 5, one end of the wire is connected to the wire pull turntable 5, and the other end of the wire is connected to the other end of the heating underground pipe 1, and the microprocessor is connected to the host computer via an RS485 interface.

[0010] The water level measurement module of the present invention comprises a water immersion sensor arranged at a monitoring node on an underground pipe well, which is used to detect whether there is water at the monitoring node of the underground pipe well. The water immersion sensor is connected to a host computer via an RS485 interface and issues an early warning via the host computer.

[0011] The temperature measurement module of the present invention comprises a temperature sensor arranged on an underground pipe well, which is used to collect the temperature of the underground pipe well.

[0017] When the underground heating pipe is displaced, the pull wire drives the pull wire turntable to rotate, which in turn causes the infrared receiving board to rotate. The infrared receiving board is provided with a receiving tube. The microprocessor can calculate the displacement change of the pull wire according to the changes in the connected receiving tube on the infrared receiving board and the angle change of the rotating shaft, and then determine the displacement change of the underground heating pipe. When the displacement change is too large, the host computer can issue an early warning.

[0018] The compensator displacement monitoring module, the water level measurement module, the temperature measurement module, the pressure measurement module and the gas detection module can realize the environmental monitoring of the heating underground pipe well, thereby improving the reliability of the heating system.
