Description

Technical Field

[0001] The utility model relates to a low-power pipeline burial depth monitoring device, belonging to the technical field of natural gas pipeline monitoring. Background Art

[0002] Water damage disasters are a special type of geological disasters. It mainly refers to the soil erosion caused by the flow of water when the water body flows through the pipeline and the surrounding rock and soil masses, and causes phenomena such as the thinning, exposure, and suspension of the pipeline coating. Water damage disasters are one of the main geological disaster risks threatening the safety of long-distance oil and gas pipelines. Compared with other pipeline geological disasters such as collapses, landslides, and debris flows, water damage disasters have the largest number and the widest influence. In particular, oil and gas pipelines crossing river channels and laid along river channels are most threatened by floods. With the rapid development of long-distance oil and gas pipeline technology in China, pipelines inevitably cross river channels or are laid along riverbanks. Under the action of river channel evolution and flood scouring, it is extremely easy to cause insufficient pipeline burial depth, suspension or even fracture. Especially in some areas with complex terrain and frequent seasonal floods, the stress state and load distribution of pipelines are more complex, and the threat of floods is more serious. Therefore, improving the monitoring and early warning level of pipeline flood disasters is crucial for the safe operation of pipelines.

[0003] For the monitoring and early warning of pipeline water damage disasters, each pipeline operation unit usually uses a hydrometeorological early warning platform to conduct macro monitoring and early warning of rainfall, river water level, flow rate, etc. along the pipeline, providing a decision-making basis for the early prevention of regional pipeline flood disasters. However, this method cannot conduct local monitoring and early warning of the relative position relationship between the pipeline and the riverbed or riverbank, and it is difficult to discover potential water damage risks. For the scour of the riverbed of the pipeline crossing the river, the underwater pipeline burial depth detection technology based on the electromagnetic method is usually used. However, the use cost of such equipment is relatively high, and it is generally detected once every 3 to 5 years, and it is impossible to conduct real-time monitoring and early warning of the pipeline burial depth. For the erosion of the riverbank of the pipeline along the river, technologies such as satellite remote sensing, unmanned aerial vehicles, and remote video monitoring are usually used. Although it can realize the identification of water damage disasters in an unattended state, in some areas with harsh climate and complex topography and landforms, related equipment is easily damaged destructively, and it is difficult to achieve continuous monitoring.

[0004] In view of the above problems, on the basis of summarizing the experience and related achievements of pipeline water damage risk management, starting from the disaster formation law and distribution characteristics of pipeline water damage disasters, a low-power pipeline burial depth monitoring device is developed.
