AI Technical Summary

Technical Problem

Existing pipeline leak detection technologies have low detection accuracy in multi-inlet and multi-outlet pipe sections, making it impossible to quickly locate leak points. Furthermore, the mounting brackets of existing sonic flow sensors cannot flexibly adapt to pipes of different sizes, resulting in low detection efficiency.

Method used

The ultrasonic flow sensor mechanism collects real-time flow data at the inlet and outlet of each pipe section. Combined with the data processing module, the flow deviation ΔQ is calculated, and the leaking pipe section is marked on the topology map by the positioning display module. It is compatible with multiple inlet and outlet pipe sections, and the mounting bracket of the ultrasonic flow sensor mechanism is adjustable to accommodate different pipe sizes.

Benefits of technology

It enables accurate leak detection of pipe sections with multiple inlets and outlets, reduces false alarms and missed detections, improves leak handling efficiency, adapts to different pipe sizes, and simplifies installation and maintenance processes.

Abstract

The application relates to the technical field of pipeline detection, and discloses a pipeline leakage detection device with a leakage point positioning function and a detection method, which comprises a pipeline system, an acoustic flow sensor mechanism, a data acquisition module, a data processing module and a positioning display module. The pipeline system comprises at least one pipe section, and one acoustic flow sensor mechanism is arranged at each of N inlet ends and N outlet ends of each pipe section. The data acquisition module is used for receiving flow data collected by all acoustic flow sensor mechanisms. The data processing module is used for receiving flow data transmitted from the data acquisition module, calculating flow deviation Delta Q of each pipe section, and the positioning display module is used for displaying a topological graph of the pipeline system. When the data processing module determines that the flow deviation Delta Q of a certain pipe section is greater than 1%, the positioning display module marks the pipe section in the topological graph with a color. The application can accurately reflect flow loss of the pipe section, ensure detection precision, effectively identify slight leakage, and reduce the false negative and false positive rates.
