FIELD: hydraulic engineering, particularly means to close water-discharge weir or dam orifices and to regulate water level in water storage pond.
SUBSTANCE: automatic hydraulic gate comprises counterweight and rotary sheet performing rotation about horizontal axis and having working chamber located over the axis of sheet rotation. The working chamber comprises adjustable water intake means. Drainage orifices are created in working chamber from lower pool side. In closed state the sheet may be supported by weir still and by spillway piers so that the sheet is inclined towards lower pool. In opened state the sheet may be supported by spillway piers. Water intake means may be filled with water from upper pool and has inlet orifice located over axis of sheet rotation. Inlet water intake means orifice may be arranged above overflow ridge of the sheet.
EFFECT: increased operational reliability and prevention of water level elevation in upper pool over predetermined mark.
