Rigid plugging device for leakage of fluid pipeline under pressure

The utility model provides a rigid plugging device for leakage of a fluid pipeline under pressure, which comprises a shell with a cavity inside and first pipeline grooves at two ends, and is characterized in that the shell is formed by combining two same half shells, glands with second pipeline grooves are arranged in the first pipeline grooves at two ends of each half shell, and the second pipeline grooves are arranged on the glands. A sealing ring connected with the pressurized fluid pipeline in a matched mode is arranged in the second pipeline groove of the gland, a first semicircular flange plate is arranged at the outer end of the first pipeline groove, and a plurality of first screw holes are formed in the first semicircular flange plate. After the two half shells are rapidly wrapped and fixed to the leakage position of the fluid pipeline under pressure, the two ends of the shell are sealed through the glands and the sealing rings, the leakage position of the fluid pipeline under pressure is blocked, th
