[0001] The application belongs to the technical field of pipeline leakage detection, and particularly relates to a pipeline leakage detection device. BACKGROUND

[0002] The pipeline leakage detection device is a device for realizing real-time monitoring and positioning of pipeline leakage by using fiber grating sensing technology. The working principle is that, by using the Bragg diffraction principle of the fiber grating, the fiber grating sensor senses the change of the external environmental parameters by monitoring the Bragg wavelength change. When the pipeline leaks, the temperature, stress and other parameters near the leakage point will change. These changes will be captured by the fiber grating sensor and converted into identifiable electrical signals through the signal demodulation system, thereby realizing the monitoring and positioning of the leakage.

[0003] The existing pipeline leakage detection device, when in use, fixes the grating sensor on the circumferential side of the pipeline through the clamp on the pipeline leakage detection device.
