FLOODGATE ACT SHALLOWS

摘要

A rotary floodgate having the function of shallows is provided to reduce manufacturing man-hour by simplifying the structure of a cut-off plate and an opening and closing device, to be operated strongly and exactly by applying the driving method by gear combination, and to keep tightly by installing a watertight member between a cutoff plate and a waterway. A rotary floodgate(A1) having the function of shallows comprises supports(2) installed to two sides of a waterway(100), a cut-off plate(4) inserted to the waterway and fitted with arms(46) at two ends to be coupled with the supports by shafts(49) to be rotary, a lower body(6) provided with a groove fitted with the cut-off plate and installed to the bottom of the waterway, and a driving device(8) rotating the shafts formed on two ends of the cut-off plate to open or close, wherein a watertight member is installed to the boundary of the top of the lower body and a groove of the lower body to be in contact with the outside of the cutoff plate and composed of an elastic plate contacted with the outside of the cutoff plate and a fixture of a bolt and a nut to install the elastic plate to be detachable, and many rotary bars(5) are installed to the lower body and rotated vertically when the cutoff plate rotates and opens upward to block a gap to prevent drowning.
