[0027] Working principle: when a connecting joint of a dredging pipeline is used, in the initial state, firstly, the first pipeline 1, the first flange 101, the second flange 102 and the second pipeline 103 are connected by means of a sealing gasket 104 and a bolt 105, and the first sealing cover 2 and the second sealing cover 201 arranged outside the first pipeline 1 are fixed at the connection between the first pipeline 1 and the second pipeline 103 by means of a fixing bolt 203, and a sealing ring 205 and a sealing strip 207 are arranged between the first sealing cover 2 and the second sealing cover 201, so as to prevent external water vapor or corrosive substances from contacting with the first flange 101 and the second flange 102 to cause rust, and a baffle 302 and a prompt column 303 are slidably raised and lowered in a transparent cover 301 arranged on the first sealing cover 2, and a push rod 304 connected to the bottom of the baffle 302 is connected to an air bag 307 through a bottom plate 305 and a connecting rod 306, so as to monitor water seepage in the first pipeline 1;

[0028] When it is necessary to observe whether the connection between the first pipe 1 and the second pipe 103 is leaking, first, when there is no water leakage at the connection between the first pipe 1 and the second pipe 103, the baffle 302 and the prompt column 303 are always at the bottom of the transparent cover 301 under the traction of the connecting rod 306 and the airbag 307, and the prompt column 303 cannot be observed through the transparent cover 301. If water leakage occurs at the connection, the seeped water will remain in the first sealing cover 2 and the second sealing cover 201. When the connection continues to leak water and the water level in the first sealing cover 2 and the second sealing cover 201 rises, the airbag 307 will float on the water surface and rise with the water level, and the rising airbag 307 uses the connecting rod 306, the bottom plate 305 and the push rod 304 to push the baffle 302 and the prompt column 303 upward, so that the outside can directly observe the prompt column 303 through the transparent cover 301, so that it is known that water leakage occurs at the connection between the first pipe 1 and the second pipe 103.
