ENERGY-EFFICIENT AUTOMATED IRRIGATION SYSTEM WITH LOW-HEAD SPRINKLING MACHINES OF CIRCULAR ACTION Russian patent published in 2010 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: system includes low-pressure pump, low-pressure supply pipeline, high-pressure pump, high-pressure supply pipeline, central control panel of irrigation system. Low-pressure pump is connected to low-pressure supply pipeline of irrigation network. Inlets of watering pipelines of low-pressure sprinkling machines are connected to low-pressure supply pipeline of irrigation networks via locks. High-pressure pump is connected to high-pressure supply pipeline. Supply lines of low-pressure sprinkling machine hydraulic drives are connected to high-pressure supply pipeline through cutoff valves. Central control panel is connected by communication and supply line to unit of sprinkling machines operation control. Unit of control is connected to line of electric accident protection and drive of cutoff valve, and also to electric drive of the second valve, flow metre, sensors of sprinkling machine position on area, sensor of the first support trolley wheel travel and sensor of infiltration moisture flow monitoring in active soil layer. Drive of cutoff valve is installed at the inlet of machine hydraulic drives supply line. Drive of pumps and generator is arranged in the form of water wheel. Water wheel is installed in irrigation channel. Central control panel is connected to automatic weather station. The second valve is installed at the inlet of sprinkling machines control line. Flow metre is installed at the inlet of sprinkling machine. Electric drive of the first valve is included into line of electric protection. Electric drive of the first valve is installed at the inlet of master support trolley hydraulic drive.

EFFECT: design makes it possible to use energy of water flow in irrigation channel for operation of irrigation system pumps drive, to prevent hydraulic shocks in irrigation system, to simplify design of automated system of sprinkling machine motion control and to prevent losses of irrigation water for depth filtration.
