By reducing the diameter of the guiding gun head 2, it is convenient for the guiding gun head 2 to cooperate with the support rod 6 to displace in the underwater pipeline. The inspection camera 5 is used to detect the position in front of the device. With the signal transmission of the underwater cable, the damaged position of the underwater pipeline can be quickly determined. As the plugging rubber layer 1 and the support rod 6 are inserted and located below the damaged position of the pipeline, an external air pump supplies air into the air flow channel 10, so that the air flow channel 10 inflates the inside of the plugging rubber layer 1, making the plugging rubber layer 1 bulge and expand like a balloon, so that the plugging rubber layer 1 and the flexible steel wire 15 are integrally attached to the inner wall of the underwater pipeline. The limiting silica gel ring 16 is used for internal traction to avoid excessive unilateral bulging. As the plugging rubber layer 1 can adapt to the shape and size of the pipeline after inflation, it can achieve a tight fit, thus achieving a good plugging effect and increasing the overall practicability.
