Automatic detection device and detection method for water leakage of water pipeline

Abstract

The invention provides an automatic detection device and a detection method for water leakage of a water pipeline, well solving the problem of pipe network monitoring. The detection device is simple in structure and energy-saving, instantly reports leakage and does not need to maintain in fixed time. The automatic detection device for the water leakage of the water pipeline comprises a detection unit, a transporting unit and a processing unit, wherein the detection unit detects water leakage information and converts the water leakage information into an electronic or digital signal, and after being initialized, the detection unit automatically searches the transporting unit; the transporting unit receives detection information and transports the detection information to the processing unit; the processing unit receives and processes the detection information transferred by the transporting unit; and power is supplied for the detection unit by a water battery; and the water in the water battery is supplied by water leaked from a water pipeline. The automatic detection device has the characteristics that the water battery is applied to leakage detection of a water pipeline, and application scenes comprise families, office buildings and municipal engineering.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to the field of active water leakage detection of water pipes. Background technique [0002] A water battery is a new type of battery that generates electricity by injecting water into the battery. The basic principle is to use the different potential difference characteristics of different metals, add water to activate and generate current, thereby providing electric energy. The advantage is that no harmful substances are used, and it can be reused only by replenishing water. Since the water battery only produces a chemical reaction after adding a certain amount of water, it can be stored for more than 10 years if it is not filled with water. Water batteries are often used in small power consumption electronic products such as pocket radios, electronic small alarm clocks or flashlights, and are suitable for storage in homes and public facilities for backup.

AI Technical Summary

Problems solved by technology

[0003] Existing water pipe leakage detection is generally carried out with the assistance of various sensors, including related leak detection method, audio-audio leak detection method, automatic leakage sound recording and monitoring method, partition leak detection method and other methods. Leakage method is the main method, although active leak detection method has also appeared, but due to cost, installation difficulty, power supply maintenance and other issues, the popularity is still not high

Most of these water leakage detection nodes are powered by batteries or mains power supply. The disadvantage is that the power supply must be provided for a long time, and there are problems in battery replacement and power supply maintenance.
