COMBINED IRRIGATION SYSTEM Russian patent published in 2016 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to hydrotechnical land reclamation, primarily to drying lands in agriculture with automatic control of ground water level. System consists of combined drying-humidification collector, which is connected through drain wells of drain collectors. Drain wells at drying-humidification collector are equipped with automatic controllers of one-way levels, and intermediate shafts are equipped with regulators of two-way level. Collector head regulator consists of well 12, divided by baffle 13 into two vessels 14 and 15. Control membrane of chamber 16 is connected by rod 17 with valve 18 and is installed in vessel 14. Second vessel 15 comprises float level gauge 22, rigidly connected with rod 23, connected by hinge joint 24 with one arm bent double-arm lever 25, arranged on horizontal axis 26 of rotation, arranged on support 27, which is fixed rigidly on vertical knee-shaped pipe 28. Knee-shaped pipe 28 on top is equipped with valve 32 connected rigidly to second arm of lever 25. Lower part of knee-shaped pipe 28 is connected by linking channel 33 with adjustable valve 34 with control membrane chamber 16, which in its turn is connected with collector mouth 38 via linking channel 36 with adjustable valve 37.

EFFECT: technical result is simplification of design, improvement of reliability and accuracy of control.
