Watering controller for Irrigation canal

摘要

The present invention relates to agricultural irrigation which makes the operation smoothness, as well as the pressure in the lower regions of the water makes it possible to fully automate the supply and interruption of the water.; Water supply device according to the prior art is the water supplied to the water supply device as being only the device is working area having a significant degree of water pressure by an external pressure water the bar was a limit not available in the place naturally flowing in through a common channel the invention open-close means (4) and, by detecting the level of nonmul the switching means to control that the water is obtained is obtained chamber (1) and, the inlet water chamber available, go to the discharge chamber (2) (4 ), the method being composed of a level sensing means 5 for operating the closing means (4) consists of a valve 40 having buoyancy, said water level sensing means 5 and the valve 40 is a hinge shaft ( 42) the valve 40 by the lowering operation of to the center through to the load (41) for pivoting the float 50, the valve 40 by the raising operation and close the through hole 31, a float (50) to the by configured to be able to open the through hole 31, the life of the crop Let it supplies the water to the rice after adjusting a water level suitable to six times and automatically stop the supply of water at the time of reaching the discussed water level adjusting water level, the discussion water is natural evaporation of the water at the point where the water level is low, it can automatically feed will be effective to prevent the waste of labor and precious water for farmers.
