Abstract

PURPOSE: To roll and close a dam gate in stages in accordance with the flood rate of a river by arranging several varieties of floats in accordance with water levels.
CONSTITUTION: A float 10 rises in accordance with the rise of the water level in a standing dam gate 2, an arm 9 is inclined and a float volue 8 is opened. The operational oil in a hydraulic cylinder 1 opens a check a valve 12 by hydraulic pressure through a pipe 3 a bypass 7, the float valve 8. Therefore, the operational oil from an accumulator 13 opens a check valve 4 and the operational oil in the hydraulic cylinder 1 reaches are oil tank 5. In a short time the hydraulic pressure of the accumulator 13 reduces and blocks the check valve 4. At this moment the dam gate 2 stops rolling. The rollings of the dam gate in the following stages are carried out in the sequence of the second, the third float.
