ARRANGEMENT FOR ENERGY DAMPING OF WATERWAYS Russian patent published in 2017 - IPC E02B8/06 

FIELD: building.

SUBSTANCE: invention relates to hydraulic engineering, namely for the energy damping after pressure conduits in the receiving pit. The arrangement for damping of water flow energy involves stilling basin 1, a supply conduit 2 and outlet channel 4. The upper part of the well 1 has the form of a truncated cone 3, in which cavity the reflectors of the flow 5 are installed executed in several levels with their large bases to the direction of the bottom 7 of the well 1 and are arranged symmetrically to the vertical axis of the well 1. The pressure face of the reflectors 5 faces the side walls of the truncated cone 3. Below the reflectors 5 of the flow at the end of the truncated cone extension 3 and at some distance from the lower base of the reflector 5 in the walls of the truncated cone 3 lateral cycle-damping bowls 6 are located. The bottom 7 of the well 1 has an extension in the direction of its outlet channel 4. Additional closed damping chamber 8 is situated behind vertical cantilevered wall 9 and the chamber floor 8 is situated in one plane with the bottom 7 of the well 1 and has a threshold 10. The damping chamber 8 has a partition wall 11 at its end and is connected through the outlet 12 to the outlet pipe 13 and exhaust channel 4. The partition wall 11 is designed to change the direction of the effluent from the outlet of the well 1 between the vertical cantilevered wall 9, which ultimately reduces bottom and surface speeds of the outlet pipe 13.

EFFECT: at all sections the flow is intensively damped, the high degree of protection of the exhaust channel from dynamic effects of excess energy of high-speed flow of the supply conduit is obtained, which increases the reliability of the arrangement, the exhaust channel length is reduced and the need for the well arrangement in the downstream channel is eliminated.
