AI Technical Summary
The existing sluice gate's filter screen is clogged due to sediment and debris from the bottom of the river, affecting the filtration effect.
A sliding baffle and drive assembly are installed inside the filter frame of the gate. The baffle is driven by a motor to slide back and forth inside the filter frame. The comb-tooth rack moves the silt and leaves, and the bottom column prevents the silt from clogging the filter holes. The garbage is also collected simultaneously when the gate is raised.
This effectively prevents filter clogging, ensures timely garbage removal, prevents downstream water pollution, and improves the filtration and garbage disposal efficiency of the gate.
