DRAINAGE RUNOFF REGULATOR Russian patent published in 2017 - IPC E02B11/00 G05B11/00 G05D9/02 

FIELD: agriculture.

SUBSTANCE: regulator includes a well 1 with an inlet branch pipe 2 of a drain, a float chamber 3 and an autonomously floating large float 4. The autonomous floating receiver has the necessary fit for water drainage and is made in the form of an inlet socket 5 with the large float 4 covering it. The inlet socket 5 is connected by a discharge flexible hose 6 with a drainage pipe 7. The body of the inlet branch pipe 5 on the outside is equipped with an inlet 10 with an adjustable locking element 11 and with a small float 13. The locking element 11 is made in the form of a cone and is arranged in the guides of the latch 12. The small float 13 is connected to a flexible link 15 fixed to a screw 16 with a nut 17 with the possibility of moving up the autonomously floating receiver. The autonomous floating receiver is arranged between the stops 8 and 9 with the possibility of freely moving between them. Due to the pushing device made in the form of a pair of screws 16 and 17, the inlet socket 5 housing with the covering large float can be mounted upwards in case of exceeding the groundwater level above the water level in the well.

EFFECT: flexible, differentiated regulation of predetermined levels above the territory under command during the vegetation period to regulate groundwater, simplifying the design.
