ENERGY DISSIPATOR FOR OPEN CANALS Russian patent published in 2015 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: vertical longitudinal flow directing element 4 in the form of supporting pier with radome 7 in the lower part is installed in steep canal 1 with the revetment walls and bottom between the longitudinal walls 5 and 6. The length of the flow directing element 4 is larger than the length of vertical walls 5 and 6. The radome 7 is oriented along the axis of transit canal and divides it into two canals with equal input cross-sections. The end portion of the radome has convex shape. Lateral walls of the canal are made with annular stilling pools 12, 13. Flat vertical gate 8 and 9, which is the regulating device for annular chamber 12 and 13 designed in the form of knee-shaped turn to at least 180° relative to the initial portion, fixed to the wall of steep canal 1, is pivotally attached to the lower ends of the end longitudinal walls 5 and 6. The height of walls 5, 6 and 4 is equal to the height of canal 1 walls. Pivotally flat vertical gates 14 and 15 oriented along the transit canal at an angle of 25-35° to the walls of canal 1 are fixed additionally opposite the radome 7 from side of the convex outer form to the walls of steep canal 1.

EFFECT: water level pressure boosting is reduced in front of the separation walls, which improves the reliability of the device operation.
