Specifically, the plugging sleeve assembly 210 is composed of a first semicircular rigid shell 211 and a second semicircular rigid shell 212, which can wrap the elastic lining assembly 230 under the action of the tightening assembly 220 and fasten the elastic lining assembly around the outer wall of the leakage pipeline 100 by synchronous extrusion from the periphery, so as to play a plugging role on the leakage pipeline 100.
When the plugging sleeve assembly 210 is specifically disposed, one end of the first semicircular rigid casing 211 and one end of the second semicircular rigid casing 212 are connected and disposed by the first connecting bolt 213, and at the same time, the first semicircular rigid casing 211 and the second semicircular rigid casing 212 can rotate around the first connecting bolt 213 to form a closed loop that can be opened and closed.
When the plugging sleeve is specifically arranged, a plurality of grooves can be formed in the outer walls of the first semicircular rigid shell 211 and the second semicircular rigid shell 212, so that the weight of the plugging sleeve assembly can be reduced, and the plugging sleeve is convenient to operate and use.
