A leak detection device and method for pipeline transfer fittings

Abstract

The invention discloses a pipeline connecting pipe fitting seepage detection device and method. The pipeline connecting pipe fitting seepage detection device comprises a central controller, four rainwater sensors and a warning unit, wherein the four rainwater sensors and the warning unit are connected with the central controller respectively, the four rainwater sensors are the rainwater sensor A, the rainwater sensor B, the rainwater sensor C and the rainwater sensor D, the rainwater sensor D is installed at the vertical-gravity bottommost position perpendicular of a pipeline connecting pipe fitting, and the rainwater sensor A, the rainwater sensor B and the rainwater sensor C are respectively installed above the pipeline connecting pipe fitting and the left-side position and the right-side position of the pipeline connecting pipe fitting. The analog signal output ends of the rainwater sensor A, the rainwater sensor B and the rainwater sensor C are respectively connected with an analog signal I / O port of the central controller, and the digital signal output end of the rainwater sensor D is connected with a digital signal I / O port of the central controller. The pipeline connecting pipe fitting is detected by combining the four rainwater sensors, the situation from humidity, water existing and water seepage of the pipeline connecting pipe fitting is judged to achieve a trend prediction warning function.

Description

Technical field [0001] The invention relates to the field of pipeline leakage detection, in particular to a pipeline transfer pipe fitting leakage detection device and method. Background technique [0002] The water supply official website is a piping system for delivering and distributing water to users in water supply projects. It is composed of pipelines, pipe fittings and auxiliary facilities, among which the pipe fittings between pipelines include flanges, gate valves, exhaust valves and drain valves, etc. The facilities include regulating structures (pools, water towers or water columns) and water supply pumping stations. The water pipe network is an important part of the water supply system. The safe operation of the water supply network is directly related to the economic benefits and sustainable development of the water supply enterprise. Water supply pipelines are laid underground, streets, buildings and other places. Due to the quality of the initial pipeline construc...

Problems solved by technology

However, this kind of water leakage detection system uses point-based one-dimensional judgment, and judges the signal based on whether water leakage occurs or not, that is, "leakage" and "no leakage". The management of potential safety hazards in communication base stations cannot make predictions, and it is easy to cause false alarm information through single-point one-dimensional detection, so the complete safe operation of equipment cannot be guaranteed.

Moreover, the implementation of this kind of water leakage system will involve issues such as integrated wiring, alarm distance, positioning, and networking, which are limited by the geographical environment of the computer room, resulting in high costs and high maintenance thresholds.
