Claims

[Scope of utility model registration request]

A float chamber is provided next to the waterway, and a gate that dams the waterway and adjusts the water level, and a float floating in the float chamber are fixed to the same axis via an arm and a float arm, respectively, and the buoyancy of the float is Therefore, in an automatic water level adjustment gate that opens and closes the gate, a suction pipe is provided that penetrates the wall of the float chamber and projects into the downstream waterway, and the float arm is attached to the shaft with the center of the shaft centered. An automatic water level adjustment gate characterized in that the horizontal line passing through the gate bisects the operating angle of a float arm that rotates from rest to fully closed.
