TWO-WAY WATER SEPARATOR FOR CHANNELS WITH A LARGE SLOPE Russian patent published in 2019 - IPC E02B13/00 E02B8/02 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering and can be used for one-sided or double-sided stabilized flow rate of water, both in irrigation and diversion channels of micro-HPP with turbulent flow mode and super-storm (wave) flow mode. Water separator comprises inlet (1) and transit (2) channels interfaced with water intake gallery (3), covered with splitter in form of U-shaped slab overlapping (9) and located above bottom of supply channel (1) and bottom of transit channel (2) with formation two parts from chambers 10 and 11. U-shaped slab overlapping (9) has front inclined wall with horizontal shield (28). Rear part of wall (12) of overlap slab (9) is fixed to axis of rotation (13) in front of water intake hole of gallery (3) at bottom of recess of bottom of transit channel (2). U-shaped floor slab (9) comprises a fixing vertical partition (14) with a lower freely stepped end (15) opposite threshold (16) at the bottom of supply channel (1). Overlapping slab (9) has inside slit (17), partition (14) of which is fixed to plane of overlap slab (9). Above posterior wall of threshold (18) of gallery (3) is fixed vertical ledge (19), in which guide groove (20) is made for installation of end of rod (21) with valve (22), overlapping slit (17) between stepped end (15) and threshold (16) in closed position. A compression spring (24) is put on stock (21), resting against the end face of vertical ledge (19), by the other end spring (24) is fixed by the end face of valve (22). Rear wall (12) of overlap slab (9) has opening (23) for end stroke of rod (21). Lower part 4 (bottom) of gallery (3) is inclined to each outlet channel.

EFFECT: improving carrying capacity of operation with maintaining stabilization of discharge rate and throughput capacity due to pressure static pressure of water under superimposed overlapping above gallery with overlapping plate and improving water inlet in supply channel ahead of water intake hole covered by vibro-grate.
