[0028] Working principle: When in use, the driving motor 12 drives the driving wheel 14 to rotate, and then drives the driven wheel 8 below to rotate through the connection of the chain 10. The driven wheel 8 drives the shaft 9 to rotate during the rotation, so that the flip plate 7 is rotated from the inside to the outside, so that a blocking structure is formed between the flip plate 7 and the upper baffle 6, and the water flow is cut off. When it is opened again, it only needs to drive the flip plate 7 to rotate into the upper baffle 6, so that the bottom channel is in an open state, and the water flow can flow;

[0029] The ultrasonic flow meter 16 can detect the flow changes in the front and rear pipes, and feed back the acquired data to the controller 15, which then feeds back to the user terminal, so that the user can know remotely. The user can control the controller 15 by wireless control, and then control the drive motor 12 to turn on through the controller 15, so that the flip plate 7 can rotate and adjust the opening and closing state, so that the user can perform water cut-off operation conveniently.
