TWO-SIDED WATER DIVIDED FOR CHANNELS WITH STEEP SLOPES Russian patent published in 2018 - IPC E02B13/00 E02B8/02 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to hydraulic equipment and can be used to draw water from channels with steep slopes, for which there is a significant fluctuation in water levels, as well as in conditions of large bottom-bed loads. Division gate comprises approach (1) and a transit (2) channels connected by intake gallery 3 covered by a splitter in form of plane plate (12) and located in the same plane with the bottom of approach channel (1). Gallery 3 has a slope (4). Splitter, made in form of a plane plate (12), is applied on pipes (13) and has bypass channels (14) in its front part. Short pressure pipes (13) are laid on slope (4) towards the bottom (5) of gallery (3). Front part of splitter under grid (16) with bypass channels (14) is made by a regulator in form of fixed turntable sections of valves (17) on axis (18) with drive (19). Rear part of splitter is made with bafflers (20), which have baffles (21) and cover intake holes (22) in the plate plane (12), and they form depletion curve of flow, which provides attraction of sediment downstream in transit channel (2). Water additionally through intake holes enters in gallery (3), where it mixes with the main flow divertor from short pressure pipes (13), and is taken into tail-water channels (8, 9).

EFFECT: improves efficiency of work by improving conditions for water entry and reducing pressure in front of intake hole, covered with a grid.
