AI Technical Summary

Technical Problem

Existing traditional leak detection technologies have limitations in terms of resolution, response delay, and resistance to environmental interference in detecting minute leaks. They are particularly difficult to deploy and maintain in extreme environments such as the deep sea and outer space. Furthermore, current research has failed to effectively combine the intrinsic link between the self-powered galvanic cell mechanism of liquid metal and pipeline leak detection.

Method used

By constructing a liquid metal bubble generator, leaked gas forms bubbles on the surface of liquid metal and their rupture activates a galvanic cell reaction. Electrical signals are collected in real time, and a linear correlation is established between the amplitude of the electrical signals and the volume, frequency, and flow rate of the bubbles, thereby achieving real-time monitoring and control of self-powered power supply.

Benefits of technology

It achieves highly sensitive, real-time monitoring of micro-leaks in pipelines, accurately identifies the severity and location of leaks, requires no external power source, is suitable for long-term deployment in extreme environments, and provides an innovative monitoring tool.

Abstract

This invention discloses a method for real-time monitoring and control of electrical parameters in liquid metal pipelines, belonging to the field of real-time monitoring and intelligent sensing technology. The method utilizes a liquid metal bubble generator to convert the mechanical event of bubble collapse caused by pipeline leakage into a quantifiable electrical signal. This liquid metal bubble generator comprises liquid metal and an electrolyte. When a bubble collapses on the surface of the liquid metal, it instantly destroys the oxide layer and activates a galvanic cell reaction, generating a self-powered electrical pulse signal. This method achieves autonomous and highly sensitive discrimination of the severity, flow rate, and location of micro-leakage in pipelines by real-time monitoring of the amplitude and frequency of the electrical signal and establishing a linear correlation between it and the bubble volume and gas flow rate. This method requires no external power supply, has high energy efficiency and anti-interference capabilities, and provides an innovative solution for intelligent pipeline monitoring in extreme environments.
