AUTOMATED WATER OUTLET FOR CONTROL OF LOWER POOL LEVEL Russian patent published in 2020 - IPC E02B13/02 G05D9/00 A01G25/16 

FIELD: construction.

SUBSTANCE: invention relates to irrigation systems and can be used to control the lower pool level on channel support structures, as well as to control closed reclamation water reservoirs of reclamation systems. Automated water outlet for control of the level of the lower pool includes a supply pipe with a water outlet hole, in which there is a body of a water level regulator, consisting of a gate on a horizontal axis of rotation with an upper platform on the support, a control chamber with a cover, an elastic shell communicated with the pools, a supply pipe with a vertical inlet branch pipe and an outlet nozzle with holes. In one of the outlet holes of the outlet branch pipe there is a control valve with a rod having through holes and a movable float level sensor, and the other hole enters the elastic shell of the control chamber. Device has a detachable tuck-off filter installed in the vertical inlet branch pipe of the supply pipe, made in the form of a pipe, the upper end of which is located above the level of the upper pool, and the lower one is sealed and is perforated on the water head side and is located from the bottom of the water level regulator body at a distance equal to at least 1/2 of the diameter of the water outlet hole. Removable tamper-proof filter has hole aligned with feed tube inlet hole. In the control chamber cover above the edge of the upper pad of the bolt there is a screw for adjustment of the lifting height of the bolt. Control valve has the shape of a cone, the vertex of which is connected to the rod, which is equipped with a system for adjusting the height of the movable float level sensor, made in the form of a guiding tube with holes and a securing pin.

EFFECT: higher efficiency of device due to wider range of adjustment and stabilization of device operation at wide range of pressure on structure.
