WATER FLOW ENERGY DAMPENER Russian patent published in 2018 - IPC E02B8/06 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to the hydraulic engineering, hydraulics, hydromechanics, and more particularly to hydraulic engineering structures intended for use in the structure of hydroelectric complexes equipped with tubular water outlets. Water stream energy absorber includes discharge outlet 1 with gate 2, the pipe 3 transition section with the outlet diffuser section 4. Inside the outlet diffuser section 4 the flow swirler 5 in the form of propeller is installed. Flow swirler 5 is attached to the rod 6 in the pipe 7, which is provided with the support crosspiece 8. To the diffuser section 4 end lower part, the conical outlet branch pipe 9 is coaxially fixed with the gap, secured by the rods 10 and installed above the hydraulic stilling basin 11 bottom. Conical outlet branch pipe 9 is made with diameter smaller than the outlet diffuser section 4 diameter. On the hydraulic stilling basin 11 walls inner surface, the flow deflector 13 with annular gap is made, oriented above the diffuser section 4 outlet end. Flow deflector 13 is located in the same plane of the outlet channel 12 bottom. Hydraulic stilling basin 11 is connected to the outlet channel 12. Entering the transition section 3 with the outlet diffuser section 4 from the discharge water outlet 1 water is swirled (crushed) by the water stream 5 swirler, which ensures the water flow good expansion at the diffuser section 4 end, and one part of the water flows through the conical branch pipe 9, and the other flows around it from the outside. Flow above the hydraulic stilling basin bottom loses energy, and the deflector 13 calms the water surface, after which the total flow exits into the outlet channel 12.

EFFECT: invention provides increase in the separated stream kinetic energy intensive quenching process efficiency and reliability and subsequent connection over the hydraulic stilling basin bottom, next the flow enters the outlet channel.
