WATER FLOW ENERGY DAMPER Russian patent published in 2024 - IPC E02B8/06 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering and can be used in end devices of closed pipelines and tunnel structures. Water flow energy damper has a water conduit, a flow swirler with the possibility of rotation on a shaft passing through a seal in the well cover, has a partition fixed above the flow swirler with an annular gap, besides, the well in the upper part has a discharge tray on the outer side, at the same time the bottom of the discharge tray is connected to a discharge pipeline having an adjustment gate. At that, the well is divided into two unequal chambers by an annular downwardly directed inclined partition separating the upper chamber of the well from the lower chamber of the well and having an annular gap, lower chamber of the well is made with a convexity downwards and is equipped with a damping rotating bowl with ends bent up at the point of narrowing of the chamber equipped with a rotation drive in the form of a shaft with an electric motor, fixed on well cover through coupling with frequency converter for smooth control of shaft rpm, wherein the upper chamber of the well is a damping chamber in the form of a cylinder with placed in it fixed cone-shaped partition with perforation holes in the form of a bowl directed towards the circular inclined partition.

EFFECT: in all sections the flow is intensively extinguished as a whole, high degree of protection of the well is achieved, which is made of two compartments of different shape and devices relative to each other in relation to the rotation shaft, and are connected to excess energy of high-speed flow of the supply water conduit, which causes reliability of the device operation.
