APPARATUS FOR CONTROLLING GROUNDWATER LEVEL Russian patent published in 2016 - IPC E02B11/00 G05D9/02 G05B11/60 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to irrigation, and can be used for automatic control of ground water drainage network drainage-humidification systems. Device includes a float drive which is designed as a two-armed lever, consisting of levers 13 and 14 with rigid locking body in form of a cone 11 with a small float 12, arm 14 is rigidly connected to a rod 15 with a large float 16 to move with one another up and down simultaneously. End of rod 15 is connected with lever 18 rigidly fastened to locking body designed as a clamping disc 19. Overflow tube 10 is connected to one end of working chamber 6, and other end comes into contact with cone 11. Cavity of working chamber 6 is connected with central part of tube 9 with throttling flow divider 8 which is placed in cavity of an additional inlet 4. Due to driving mechanism made in form of a screw pair 23 and 24, body 5 with shutoff member can be installed in zone ensure kinematic connection of two float-type drives interconnected via lever 14.

EFFECT: design of device is aimed at increasing efficiency due to connection and disconnection of device for control of ground waters, as well as simplifying design.
