Abstract

PURPOSE: To economise irrigation time also to save irrigation water by a method wherein the gate is opened by a remote control, then shut by the action of a float when the ponded area has reaches its predetermined water level.
CONSTITUTION: For starting irrigation from the closed position of the gate 6 of the outlet 12, the control button is pressed then the circuit of the coil 15 around the cylinder 13 is energized, the plunger 17 is pulled up, the oil is moved from the upper oil tank 14 towards the oil cylinder 18 to fill the upper oil chamber 20 and accordingly presses down the piston 19. Thus the connecting cable 9 is pulled, the gate 6 is raised along a rail 5 up to the position where the gate 6 is clamped at the projected point 7 with steel plates on both sides and accordingly the gate 6 is held leaving the outlet 12 opened. Water is flown into the irrigation area then reaches to the predetermined water level 1. The ring-shaped float 11 is pushed up together with the horizontal seat by the force of bouyancy, unlocks the clamping of the gate 6 at the projected point 7 by a deformation on the steel plate attached to the float. Thus the gate 6 is descended and accordingly the outlet 12 is closed.
