Abstract

PURPOSE:To automatically maintain the highest water level of paddy field by a method in which a float is provided through an arm to one side of a shaft as the center, a gate plate is provided to the other side, and a gate plate is also provided for the gate plate receiver of aqueduct in a freely contacting manner. CONSTITUTION:When water is supplied to an aqueduct 11, a gate plate 4 is opened by the weight of an arm 2 and a float 1 and water flows into a paddy field 13. When the water level of the paddy field reaches the highest level, the plate 4 is moved by the buoyancy of the float 1 in a rocking manner around a shaft 3, comes into contact with a gate plate receiver 5, and is closed. When the water level of the paddy field is lowered, the plate 4 is separated from the receiver 5 by the weight of the arm 2 and the float 1 and is opened.
