Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and in particular to a non-destructive detection device and method for pressure pipeline detection. Background Art

[0002] Ultrasonic testing is a commonly used method for pipeline inspection. It uses the propagation properties of ultrasound waves through materials to detect pipeline defects. The sound waves emitted by the ultrasonic detector are reflected back by internal defects in the pipeline, revealing the extent and location of the defect.

[0003] Chinese patent CN109519712B discloses a high-precision fault monitoring device, which includes an upper shell and a lower shell. The upper shell and the lower shell are respectively recessed to form a first plugging groove and a second plugging groove. The first plugging groove and the second plugging groove are respectively connected to a first plugging device and a second plugging device. A drive motor is provided above the upper shell, and the drive motor drives the first roller below it through the motor shaft, thereby the upper shell and the lower shell move synchronously. A vibration sensor is also provided below the drive motor, and ultrasonic flaw detectors are respectively provided in the upper shell and the lower shell. When in use, the vibration sensor is used to monitor leakage faults in the gas pipeline, and then the ultrasonic flaw detector is used to detect the leakage point. Then, the gas pipeline is urgently repaired by the first plugging device and the second plugging device. The emergency repair agent can quickly condense to achieve the effect of emergency plugging of the gas pipeline leakage point, which can achieve the effect of high-precision monitoring of gas pipeline leakage faults.

[0004] However, the structure disclosed in the above patent cannot be installed on a continuous pipeline that has already been laid for use. At the same time, it cannot adapt to the detection of pipelines with different outer diameters. In addition, the above structure cannot cross the flanges between the pipelines during detection, which is not conducive to practical use.
