The invention discloses a pipeline leakage monitoring and plugging device and relates to the field of pipeline leakage plugging. The pipeline leakage monitoring and plugging device is used for detecting the leakage position of an oil pipeline and plugging the leakage position, and comprises a valve pipeline which can move along the oil pipeline, a detection mechanism which is used for detecting the defects of the oil pipeline and arranged on the outer wall of the valve pipeline, an unpowered traveling mechanism which is used for adjusting the cross sectional area of a channel for allowing fluid to flow through in the valve pipeline, a leakage plugging mechanism which abuts against the leakage position of the inner wall of the oil pipeline in an expanding or contracting mode for plugging leakage or removing leakage plugging, and a brake mechanism which abuts against the inner wall of the oil pipeline in an expanding or contracting mode for braking or removing braking. According to the pipeline leakage monitori
