COMBINED IRRIGATION SYSTEM Russian patent published in 2018 - IPC E02B11/00 

Abstract RU 2642095 C1

FIELD: agriculture.

SUBSTANCE: invention relates to hydraulic reclamation, mainly to land drainage in agriculture with automatic regulation of groundwater levels. System is located on a reclaimable massif, divided into fields with a drainage-humidifying collector-drainage network, which has a regulator of the collector mouth in the form of a spillway. System consists of a combined drainage-humidifying collector, to which drainage collectors are connected through water intake wells. Water intake wells at drying-humidification collector are equipped with two-way automatic level controllers. Collector mouth regulator consists of well 12, divided by partitions 13, 14 and 15 into four tanks 16, 17, 18 and 19. Control chamber 20 in vessel 17 is connected by stem 21 to cone-shaped valve 22 passed through chamber 20, and stem 21 is connected to lever 23 of the articulated actuator. Vessel 17 comprises level float sensor 25 rigidly connected to stem 26 connected by a hinge to one end of lever 23, and the other end of lever 23 is provided with adjustable weight 27 located in vessel 16. Lever 23 is fixed to rotational axis 24 on the abutment in the upper part of partition 13. Stem 21 is located in guides 28 in the cover of chamber 20. Control chamber 20 is fixed to nozzle 29 fixed to the collector mouth by pipe 30. Vertical partition 14 has inlet nozzle 32 located at the bottom, the end of which flexible hose 33 is provided. Upper end of flexible hose 33 is attached to float 34 with drain diverging nozzle 35. Self-regulating mechanism consists of nozzle 35, float 34 and flexible hose 33 with inlet nozzle 32, and has a hydraulic connection in the form of a channel with vessel 17 according to the principle of communicating vessels. Discharge pipe 36 is inserted with one end into water discharge vessel 19. Vertical partition 15 has pipeline 37 in the middle, connecting vessels 18 and 19, while the self-regulating mechanism is located in vessel 18. Working volume of vessel 18 is set to receive water from vessel 17 with outlet nozzle 35 at the top with float 34, and also in the upper position of float 25 in vessel 17.

EFFECT: use of the invention will make it possible to automate the process of regulating the groundwater level, improve efficiency and reliability of operation, reduce the hazard of groundwater level rise and reduce the development of secondary salinization processes.
