Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline inspection equipment, specifically a water pipe crawling device. Background Technology

[0002] Water supply pipelines are a crucial component of urban water supply systems, typically constructed from materials such as iron, steel, cement, and fiberglass. However, being buried underground for extended periods, these pipelines are susceptible to damage due to aging, corrosion, wear, and expansion if not properly maintained. If leaks are not detected and repaired promptly, precious water resources are wasted, and the leaks can endanger nearby roads, buildings, and facilities. In severe cases, they can cause water pollution, significant economic losses, and adverse social impacts. Therefore, conducting leak detection for water supply pipelines to ensure their safe, stable, and healthy operation is of practical and far-reaching significance.

[0003] Early leak detection equipment mainly included sound leak rods, sound leak discs, and electronic sound leak meters. However, these detection methods also had certain limitations. For example, the traditional handheld listening rod technique—detecting the sound of leaks at exposed points on the pipe—was affected by background noise, pipe pressure, and the experience of the leak detector. Furthermore, leaks could not be detected at great pipe burial depths. Electronic amplified audiometers (pipe leak detectors) compared sound intensities along suspected leaking pipes using specific steps, but they were difficult to apply effectively in noisy or busy urban environments and were also affected by soil properties. Correlation analysis—using the delay of leaking sound to determine the leak location—was relatively accurate, but often ineffective for non-metallic pipes. Additionally, errors in pipe network topology, the presence of branch pipes, and sound velocity calculations could all lead to location errors. Tracer gas detection—finding leaks by detecting changes in the concentration of tracer gas along the pipe—was highly sensitive, but had stringent conditions; the direction of water flow was essential, and the presence of branch pipes could cause gas leaks, resulting in detection failure. Ground-based radar leak detection utilizes electromagnetic principles to detect underground pipelines. It locates leaks by emitting electromagnetic waves and performing reverse sampling. This method is suitable for large-diameter or non-metallic pipelines. However, it suffers from difficulties in accurately determining the initial leak point, challenging image analysis, and slow data processing. Instantaneous flow rate detection locates leaks by identifying pipeline pressure signals. It artificially generates instantaneous flow rate changes, but comparing the calculated instantaneous pressure changes with actual pressure changes under different leak location and area conditions introduces noise interference, leading to errors in the inverse problem analysis and low model reliability.

[0004] Therefore, a crawling device needs to be designed to move through the water supply pipe, so as to synchronously drive the detection device to move together in the water supply pipe. Utility Model Content
