WATER GATE OPENING CLOSING APPARATUS

摘要

PURPOSE: A floodgate opening and closing device is provided to control the fluid flow direction using a rotor according to the force applied to the flow rate of fluid. CONSTITUTION: A floodgate opening and closing device comprises a main flow path part(100), an overflow wall(210), and a sub flow path part and a rotation opening and closing unit(300). The main flow path part has a side wall. The main flow path part forms a main flow path in which fluid flows. The overflow wall has a cross section of swollen half circle. The sub flow path part forms a sub flow path inside a pair of overflow walls. The opening and closing unit is connected between a pair of over flow walls through a rotary shaft. The opening and closing unit converts the flow direction of the fluid into the main flow path or sub flow path.
