WATER FLOW BAFFLE Russian patent published in 2020 - IPC E02B8/06 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to the hydraulic equipment and can be used for the water flow quenching downstream the pressure water lines in the water cushion. Water flow energy damper includes horizontal section of underwater pipe 1, vertical outlet branch pipe 2 and water cushion 7. Water cushion 7 is divided by vertical overflow partition 6 into two unequal parts 8 and 9. One part 8 of water cushion 7 has an inlet movable telescopic pipe 3 arranged above extinguishing grate 10 located above the bottom of hydraulic water cushion 7. Second part 9 of water cushion 7 inside it contains at least two shortened horizontal reflecting plates 14 and 15 welded to its inner side walls and to partition wall 6, which in the second part of the water cushion form at least three rectangular channels in the form of water lines, for movement of the flow from overflow thereof through the edges of the vertical spillway partition 6, which, when moving in horizontal plane, alternately performs, respectively, at least four consecutive turns of 90°, 180°, 180° and 90° in vertical plane, which dampens flow energy. Lower end of movable branch pipe 3 is located below upper edge of vertical overflow partition 6, constantly immersed in water, and in second part 9 of water cushion 7 the lower horizontal plate-reflector 14 is located above the outlet hole of discharge pipeline 13.

EFFECT: increased efficiency of operation on the way of non-stationary flow of liquid, due to local collisions of pulsating water flow towards the water cushion, simplification of design and reduction of bottom speeds in flow.
