[0030] The toothed disc rod 203 penetrates through the butt joint pipe 105 and is located at the center of the front side of the butt joint pipe 105, the axis of the toothed disc rod 203 is collinear with the center line of the ball valve 204, and the ball valve 204 has a hollow spherical shape.

[0031] Firstly, the box door of the box body 1 is opened, the butt joint pipe 105 is inserted into the box body 1, the first sealing shell 103 is rotated and driven by the screw rod 101 to move vertically inside the limiting frame 102, and is abutted and fixed on the top of the second sealing shell 104, so that the function of connecting the drain pipe is realized;

[0032] Secondly, the box body 1 can collect and store the leaked water source at the connecting position of the butt joint pipe 105, the water immersion sensor 205 operates and detects by using the liquid conductive principle, in the normal working state, the probe of the water immersion sensor 205 is insulated by air, in the water immersion state, the probe is conducted, a dry contact signal is output, an alarm signal is generated, and the alarm signal is transmitted to the controller through the wire, and the controller controls the electric rod 201 to operate through the wire;
