Problems solved by technology

[0003] On the one hand, the leakage of the pipeline causes the waste of water resources and affects the operating efficiency of the enterprise
On the other hand, leaks in water supply pipes will cause soil erosion to form underground cavities, which may further cause road surface subsidence accidents

Embodiment 1

[0028] A device for locating different amounts of water leakage in water supply pipelines, including a signal receiving unit, and multiple groups of monitoring equipment arranged in an array along the length direction of the water supply pipeline, each group of monitoring equipment includes flowmeters, pressure gauges, leakage monitors, pipeline surface video, The flowmeter and pressure gauge are installed at the same location. The signal receiving unit is respectively connected to the data terminals of all components in each group of monitoring equipment. Among them, the leakage monitor is PQWT water leakage listening rod. The collection frequency of the manometer is 40-60 times / second. In this embodiment, the acquisition frequency of the manometer is 50 times / second.

Embodiment 2

[0030] The difference from Example 1 is that the acquisition frequency of the manometer is 40 times / second.

Embodiment 3

[0032] The difference from Embodiment 1 is that the acquisition frequency of the manometer is 60 times / second.

Abstract

The invention relates to the field of pipe networks, in particular to a device and method for positioning different water leakage quantities of a water supply pipeline. The device comprises a plurality of sets of monitoring devices which are arranged in the length direction of the water supply pipeline in an arrayed mode, each set of monitoring device comprises a flow meter, a pressure meter, a leakage monitor and a pipeline pavement video, and the flow meters and the pressure meters are mounted in the same position. The device and the method have the advantages that as for a system, through matched using of the flow meters, the pressure meters, the leakage monitors and the pipeline pavement videos, the three conditions of leakage, pipeline hidden leakage and pipe bursting can be monitoredwell, especially leakage and pipeline hidden leakage. According to the method, by using the system, a comprehensive identification and judgment technique for leakage, hidden leakage and pipe burstingof the water supply pipeline is formed.

Description

technical field [0001] The invention relates to the field of pipe networks, in particular to a device and method for locating different water leakage amounts of water supply pipes. Background technique [0002] Urban water supply pipelines play an important role in ensuring residents' water use and maintaining urban security and stability. A large number of water supply pipelines are laid underground in various cities. According to the Urban Water Supply Statistical Yearbook, in 600 cities across the country, the total length of urban water supply pipelines (above DN75mm) reaches more than 140,000 kilometers, and the total annual water supply reaches more than 33 billion cubic meters. The average leakage rate of the network is 15.61%, and the total leakage of the pipeline network reaches 4.5 billion cubic meters. Assume that the average cost of urban water supply is 1.10 yuan / m 3 , the annual economic loss caused by leakage in my country's urban water supply industry is as...
