DOUBLE-ACTING IRRIGATION SYSTEM Russian patent published in 2015 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: double-acting irrigation system consists of a source of irrigation, in which a water lift is mounted in the form of a hydraulic ram to lift the water to elevated areas of land. The rise of water is supplied to the supply pipeline 2, then to the storage container 3 connected through the inclined connecting pipe 5 with the shutter 6 and the well 4. The middle part of the well is attached to the double-acting irrigation network in the form of drains 7. The water lift in the form of a hydraulic ram, mounted at the river, channel, reservoir has a partitioning jumper, a tubular pipe, an accumulation chamber, a curved shutter in the form of a sector with the axis of rotation, a float with a shutter, at the end part of the supply pipeline there is a beater chamber of round section, inside which a stroke valve is mounted. The float locking device consists of a horizontal double-arm lever 42 with a rod 43 and a large float 44 and a rod 45 with a small float 46 and a support 47. One arm of the double-arm lever 42 is provided with a valve 48, and the other - with a segment shield 49, overlapping the inlet pipes of the drains 7. The double-arm lever is provided with the ability of movement for equilibration and reduction of effort on the side of the segment shield 49 with float drives in the form of large 44 and small 46 floats which can be moved along the screw of the rods 43, 45 pivotally attached to one arm of the lever. The segment shield 49 is mounted on the inlet pipe of the drain 7 with the ability of abutment in the closed position by the limiter 50.

EFFECT: invention expands the range of technical means intended for the double-acting irrigation system with a complex relief, enables to reduce the depth of the well and to increase its efficiency of operation.
