Embodiment 1

[0034] A leakage detection system for water supply and drainage pipes, such as figure 2 shown, including figure 1 In the composite pipe shown, a fluid conductive medium 4 is arranged in the composite pipe; the composite pipe includes an inner insulating layer 1, an outer insulating layer 3, and a conductive layer 2 arranged between the inner insulating layer 1 and the outer insulating layer 3 , the conductive layer can be a metal layer or other conductive medium layer, the inner insulating layer and the outer insulating layer are insulating polymer materials, and the composite pipe is used as a water supply and drainage pipe, and the interior is generally tap water or sewage, but it does not exclude all There are other wire media in the composite pipe; and a leakage detection device, the two poles of the leakage detection device are connected to the conductive layer 2 of the composite pipe, and are kept in point connection with the conductive layer. The leak detection device...

Embodiment 2

[0052] The second embodiment of the present invention provides a water supply and drainage pipe leakage detection method, refer to Figure 5 , with the following steps:

[0053] S101, the leak detection device applies a detection signal to the composite pipe;

[0054] S102. If the ground insulation resistance of the leakage detection device changes beyond a set value, it is determined that the outer insulation layer of the composite pipe or the whole is damaged.

[0055] Specifically, the leak detection device 100 includes a power supply unit 60, a signal generation unit 10, a detection unit 20, a processing unit 30, and an electrical connection with the composite pipe and the medium outside the composite pipe; the signal generation unit 10 is used for detecting The circuit provides a detection signal; the detection unit 20 is used to detect the change of the resistance to ground in the circuit, and the processing unit 30 judges whether the change exceeds a preset value, and ...

Abstract

The invention discloses a water supply and drainage pipe leakage detecting system and method. The detecting system comprises a composite pipe and a leakage detecting device. The leakage detecting device is provided with a detecting circuit. The composite pipe comprises an inner insulation layer, an outer insulation layer and a conductive layer arranged between the inner insulation layer and the outer insulation layer. Two poles of the leakage detection device are connected with the conductive layer, the leakage detection device is further provided with a grounded pole, and the grounded pole is arranged in a medium outside the composite pipe. When the whole pipe wall of the composite pipe or the outer insulation layer is broken, the ground insulation resistance of the leakage detection device changes. According to the water supply and drainage pipe leakage detecting system and method, the effects of carrying out earlier prediction and precisely locating the broken position when a water supply and drainage pipeline is broken are achieved, and the prevention capacity and first-aid repairing efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage pipeline leakage detection, in particular to a water supply and drainage pipeline leakage detection system and detection method. Background technique [0002] The urban underground pipe network is the deep underground blood vessel of the city, which plays an important role in urban construction. Water supply pipelines, drainage pipelines, natural gas pipelines, etc. are all buried underground for a long time and each plays a different role. Due to the relatively backward planning of urban underground pipelines in the early days, the distribution of them was complicated and buried deep underground, which made it difficult to manage the pipelines uniformly, and also created many problems for the subsequent construction of new cities. Leakage of underground pipelines easily caused by overdue service, aging pipelines, geological changes, poor construction, etc. is a huge challenge i...
