DRAIN COLLECTOR MOUTH Russian patent published in 2017 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: mouth of the drain collector comprises a water intake chamber 6 formed as a washing gallery and a chamber 12 separated by a partition wall 4 in the well 5. A water outlet 3 is located between the water intake chamber 6 and the second chamber 12 via the partition wall 4. At that, the water outlet 3 comprises a plug valve 11, the rod 13 of which is connected through a pivot system 14 with a float sensor 17. The plug valve 11 is oriented coaxially with the drain hole 10 of the outlet 3 with the fixed lower stem 18. The stem 18 is connected through a hinge 19 and a lever 20 with a valve 9 overlapping the outlet 8 opening. The washing gallery 6 is adjacent to the input of the outlet 8. The second chamber 12 is connected to a discharge manifold 23. Inclusion of an outlet 6 with a valve 9 in the device at the end of the bottom 7 of the chamber 6 allows to provide a link to the water outlet 3 with the plug valve 11, automatic control of water level in the well 5, as well as a possibility to protect against bottom sediments and floating debris falling into the water outlet 3. Reliability in transient modes depending on water filling and bottom sediment accumulation in the chamber 6, coming from the collector 2, will be achieved by reduced material consumption and simplified design, consisting of two chambers, one valve, and reduced number of stems that affect plug valve operation in the water outlet.

EFFECT: simplified design, reduced material consumption and improved protection of mouth operation against sediment and floating debris getting into the water outlet.
