Problems solved by technology
[0002] The use of pipelines to transport tap water is not only a large amount of transportation, but also safe and convenient. Therefore, pipeline transportation has become an important transportation method for urban water supply. Problems such as dripping and leaking have always been hot issues in the global water supply industry. However, there is no mature method for locating pipeline leaks in the prior art, which makes it impossible to accurately find the leaking point in the water supply pipeline, which not only wastes a lot of water resources , and will also affect the surrounding environment and road safety

The invention discloses a method for locating pipeline leaks. The water supply pipeline to be tested generates instantaneous water hammer waves under the action of external forces, and reverse water hammer waves will be generated when the water hammer waves propagate in the pipeline to the leak point, and the two The generation time of each water shock wave can be obtained by analyzing the vibration signal of the pipe wall of the water supply pipeline to be tested before and after the transient flow is applied, and finally combined with the propagation velocity of the water shock wave in the water supply pipeline to be tested and the application of transient The position of the flow can be used to locate the location of the pipeline leak, and the location of the pipeline leak can be accurately performed. The staff can also accurately excavate and repair the pipeline leak, which not only saves water resources, but also eliminates the existing problems of the pipeline. Security risks. The invention also discloses a pipeline leakage point locating device and system, which have the same beneficial effect as the pipeline leakage point location above.
Description
technical field [0001] The invention relates to the field of pipeline leakage detection, in particular to a method for locating pipeline leakage points, and also relates to a pipeline leakage point locating device and system. Background technique [0002] The use of pipelines to transport tap water is not only a large amount of transportation, but also safe and convenient. Therefore, pipeline transportation has become an important transportation method for urban water supply. Problems such as dripping and leaking have always been hot issues in the global water supply industry. However, there is no mature method for locating pipeline leaks in the prior art, which makes it impossible to accurately find the leaking point in the water supply pipeline, which not only wastes a lot of water resources , and will also affect the surrounding environment and road safety. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in th...
