WATER FLOW BAFFLE Russian patent published in 2017 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: baffle comprises a water line 1, a vertical branch pipe 2, a well 3, an annular air pipeline 4 with spray nozzles 5 and 6. The spray nozzles 5 and 6 are installed with inclined holes in different directions, and each nozzle is directed up and down at an angle to the plane perpendicular to the axis of the branch pipe 2. A reflective screen 8 with a curvilinear nozzle 10 of the screen 8 is placed coaxially above the outlet opening of the branch pipe 2. The gap changing mechanism 9 can be made in the form of a screw pair to move the reflective screen 8. The well in the lower part is equipped with a transverse partition 11 with bypass ports 12 with an annular inclined apron 13. The annular cavity of the pipeline 4 has a branch pipe 7 for supplying compressed air from a source, which is supplied under the pressure through the spray nozzles 5 and 6 into the cavity of the well 3 filled with the water flow.

EFFECT: increasing the efficiency and uniformity of the distribution of costs, reducing bottom speeds in the flow, improving the reliability of the device and reducing the structure cost.
