ABSTRACT:
A hydraulic timer mechanism for water irrigation is disclosed to comprise a cylindrical body having an irrigation water entrance and a number of irrigation water exits. The water exits are arranged along the same peripheral circle of the cylindrical body. A water turbine assembly housed inside the cylindrical body for harnessing the power of irrigation water flow is employed to provide rotational power for the mechanism. A speed reduction device is coupled to the water turbine assembly for reducing the rotational speed and increasing the torque produced by the water turbine. A Geneva mechanism is coupled to the speed reduction device for transforming the continuous rotational motion of water turbine assembly into intermittent motion. An energy storage device is used for storing energy provided by the rotation of water turbine that is released in a short period of time. A rotating seat coupled to the Geneva mechanism provides for aligning the irrigation water entrance to one of the irrigation water exits one at a time as the intermittent motion means is driven for intermittent rotational motion. Subsequent irrigation water distribution is therefore provided to the multiple irrigation regions attached to the hydraulic timer mechanism.
