[0041] In the present invention, the working steps of the device are as follows:

[0042] First, when the gate needs to be opened, start the motor 18 of the lifter 6. The motor 18 drives the lifter 6 to work, driving the gate knife 2 to slide upward along the sliding column 10 until the gate knife 2 is fully opened, allowing water to flow through. When the gate needs to be closed, reverse the operation of the motor 18 of the lifter 6 to make the gate knife 2 slide downward along the sliding column 10 until the gate knife 2 is tightly matched with the clamping structure of the gate frame 1 to form a seal to prevent water from flowing through. Then, during the process of opening the gate to release water, the drying net 20 of the sieve plate 7 will filter impurities in the water to prevent impurities from entering the downstream. Finally, by adjusting the speed and working time of the motor 18 of the lifter 6, the opening and closing speed of the gate knife 2 can be controlled to meet the needs of different scenarios.
