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

FIELD: construction.

SUBSTANCE: baffle comprises a round or rectangular well (1) and a supply pipe (2). In the well (1), there are horizontal dividing partitions (3-5), one side of which is adjacent to the end of a supply conduit made in the form of the supply pipe (2). The free ends of the horizontal partitions (3-5) are located with respect to the parts of the horizontal partitions (3-5) and at the end are made with fractures in the vertical plane with given angles α₁, α₂, α₃, wherein their length in the plan is made by height in steps at the ratio to the length of a drainage tray (6) with a bottom opening (7) in the bottom of the tray (6). Side walls and a rear baffle wall (9) form a weir (6). The inclined bottom of the tray (6) and the bottom after the well wall (9) are made inclined towards the discharge pipeline (10) of the well (1). The lower part of the rear baffle wall (9) of the weir tray (6) is made with two trapezoidal cutouts. When the tray (6) is mated to the bottom of the well (1), the bottom opening (7) is located coaxially to the bottom opening (12) of the well (1) at the inlet to the discharge pipe 13. The bottom opening (12) of the well (1) is made by an annular L-shaped visor, the flange of which is directed downwards towards the discharge pipe (13). The bottom opening (7) of the weir tray (6) in the center is made with the smaller diameter than the diameter of the opening (12) in the well (1) bottom. The upper border of the edge of the weir tray (6) is located at the bottom mark of the supply pipe (2), and the upper face (15) of the discharge pipeline (10) of the well (1) is located on the mark above the edge of the weir tray (6). The trapezoidal cutouts made in the lower part of the wall (9) in the plane of the well (1) bottom are directed towards the flow movement into the discharge pipeline (10).

EFFECT: increasing work efficiency due to ensuring the uniform distribution of specific consumption over the baffle width, lowering bottom velocities at the outlet, and also reducing the operating costs of servicing the baffle as a whole.
