Abstract
An automatic mechanism for pivoting a barrage gate allows the gate weir level to adjust open in the case of rapid rises in head water level, and uses a bucket to effect incremental gate opening via a winch mechanism. The bucket is located in a chamber beside the gate and has a trapezoidal asymmetric cross section, with a counterweight to maintain the bucket horizontal when empty. The bucket is filled by water which is ducted from head waters, rotates when full, empties and returns to the horizontal position. Bucket rotation effects, via a linkage, a retraction of a winch ratchet, permitting a gravitational incremental gate opening until equilibrium is reached.
