The leakage stopping device is arranged between the cavity and the side opening cavity and the pipeline. The equipment is simple in structure. After the equipment abuts against the gas pipeline through cooperation of an air bag and a guide rail, thegas leakage point is searched, in addition, a double-layer structure is utilized, the gas leakage point is sufficiently wrapped and locked, and rapid leakage repairing of the gas leakage part is achieved.
