GROUND WATER LEVEL REGULATOR Russian patent published in 2018 - IPC E02B11/00 G05D9/02 

FIELD: reclamation.

SUBSTANCE: invention relates to reclamation and may be used for automatic control of ground water level. Regulator includes drainage well 1, shut-off device 3 installed on the inlet end of the drainage pipe. Shut-off device 3 is provided with L-shaped lever 4 pivotally connected to stem 5, which is connected to the lever of floating actuator 10, hingedly by one end connected to the well side. Float 15 is shaped like a biconvex lens and is provided with shut-off device 16 in its lower part, which is made in the form of a conical needle, and in the upper part float 15 is rigidly connected to stem 26. Outlet branch pipe 17 of chamber 11 has conical locking socket 18. Locking saddle 18 of outlet pipe 17 is connected to tapering tube 19 connected by threaded connection 22 to outflow tube 20. Chamber 11 is provided with lid 23 with opening 24 and guides 25 through which stem 26 is passed, connected in the bottom part rigidly with float 15, and in the upper part through hinge 8 with the middle part of lever 10. Valve 27 is also hingedly connected to the middle part of lever 10, respectively, by stem 28. Stem 28 of valve 27 is located in cylinder 30 with return spring 31, one end of which is attached to lid 32 of cylinder 30 and the second to valve 27.

EFFECT: regulator efficiency, accuracy and operational reliability are increased by combining a float with stem and shut-off device connected to the outlet branch pipe in the bottom of the chamber, and decreased material consumption.
