Description

Technical Field

[0002] Buried PE pipe refers to pipes made of polyethylene (PE) buried underground for use in water supply, gas transportation, and other projects and facilities. PE pipes are widely used in engineering due to their unique properties and wide range of application scenarios.

[0003] After searching, a Chinese patent discloses a leakage monitoring device for an oil pipeline (authorization announcement number CN216743875U), which includes a second arc-shaped trough plate, a monitoring mechanism and a positioning mechanism. The monitoring mechanism is fixedly installed at the bottom end of the inner wall of the second arc-shaped trough plate. The monitoring mechanism includes a connecting slot, a protective box, an oil sensor, a liquid storage box and a data transmission device. The bottom end of the outer wall of the second arc-shaped trough plate is fixedly installed with a protective box, the inner side wall of the protective box is fixedly installed with a liquid storage box, the bottom end of the inner wall of the liquid storage box is fixedly installed with an oil sensor, and the bottom end of the liquid storage box is fixedly installed with a data transmission box. Although this patented technology can detect that there is oil in the oil pipe connection when leakage occurs, the oil flows along the outer wall of the oil pipe into the liquid storage box. When the oil sensor in the liquid storage box detects that there is oil in the liquid storage box, the data is sent to the data transmission device, which is transmitted to the client by the data transmission device, thereby realizing real-time monitoring of the oil pipe connection and ensuring the safety of oil transportation through the oil pipe.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the above leakage monitoring device uses the first arc-shaped groove plate and the second arc-shaped groove plate to clamp and fix the pipeline, but the above fixing structure cannot be used for pipelines of different sizes, which reduces the applicability of the monitoring device.
