Description

Technical Field

[0001] The utility model relates to the field of water supply network pipes, in particular to a water supply network pipe leakage detection device. Background Art

[0002] The water supply network pipe is an important part of the urban water supply system, used to transport water from the water source to the terminals of each user. Since the water supply network pipe is buried underground, it is difficult to detect leakage during use. At this time, workers are required to detect the leakage location in order to facilitate subsequent maintenance of the network pipe at that location. The current methods for detecting buried network pipes include acoustic detection, flow monitoring and pressure detection.

[0003] Currently, when inspecting pipelines using acoustic detection methods, sound waves are usually emitted into the pipelines through a probe. When the pipelines have water leaks, they can be detected. However, when inspecting in construction areas, the soil in the construction areas is muddy and uneven, so the probe cannot point vertically to the position of the pipeline, which leads to a misaligned direction of the sound wave emission, resulting in reduced detection accuracy. Therefore, a water supply network pipe leakage detection device is proposed to address the above problems. Utility Model Content

[0008] Preferably, the end of the connecting plate away from the pressure spring abuts against the end face of the connecting rod, and the surface of the screw is provided with an annular groove adapted for rotational connection with the connecting ring, so that the pressing block can be stably rotated and connected to the bottom of the screw to avoid separation.
