Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline leakage detection, and particularly relates to a pipeline leakage detection device. Background Art

[0002] A pipeline leakage detection device is a device that uses fiber Bragg grating sensing technology to achieve real-time monitoring and positioning of pipeline leakage. Its working principle is through fiber Bragg grating sensors, using the Bragg diffraction principle of fiber Bragg gratings, and by monitoring the change in the Bragg wavelength of light to sense the change in external environmental parameters. When a pipeline leaks, parameters such as temperature and stress near the leakage point will change. These changes will be captured by the fiber Bragg grating sensors and converted into recognizable electrical signals through a signal demodulation system, thereby realizing the monitoring and positioning of the leakage.

[0003] When the existing pipeline leakage detection device is in use, the grating sensor is fixed on the circumference of the pipeline through a clamp on the pipeline leakage detection device. When the user fixes the grating sensor on the pipeline through the clamp, it is necessary to sequentially turn multiple bolts through tools to fix the clamps on the pipeline leakage detection device to each other on the circumference of the pipeline. Moreover, when the pipeline leakage detection device is in use, the user also needs to turn multiple bolts through tools to fix the grating sensor on the clamp and wind it around the circumference of the pipeline. This installation method consumes a long working time, resulting in the user being unable to quickly fix the grating sensor on the pipeline surface. In view of this, we propose a pipeline leakage detection device. Summary of the Invention
