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

FIELD: hydraulic engineering.

SUBSTANCE: used to absorb water flow after pressure water conduits in a water cushion. A pyramidal divider is fixed in the upper part of the water flow energy absorber chamber, with its narrow part directed towards the outlet pipe, while the chamber is equipped with auger shafts located parallel to each other in height, on the outer side of each auger below the chamber cover parallelograms are placed, on the hinges of which blades are fixed, directing the flow to the spiral blades of the augers, at an angle of 45-60 degrees for each auger relative to the vertical axis of the flow, and each parallelogram is equipped with a drive for changing the angles of inclination of the blades directing the flow, and the spiral blades of the augers are made funnel-shaped with by the opposite twist of the spiral blades on their shafts, while to the pyramidal divider covering the auger shafts on top, there are nozzles with bearings installed inside them, in which the upper ends of the shaft are attached, and the lower ends of the shaft are installed in nozzles with bearings with the possibility of rotation, the nozzles of the latter of which secured to the bottom of the chamber from the side of the outlet pipe connected to the cushion.

EFFECT: increasing the efficiency of work along the path of an unsteady fluid flow due to the constructive use of the current force of the flow in the opposite direction of rotation of the screws and their vertical arrangement close to each other, while they are closed at the top with a pyramidal divider fixed in the upper part to direct the moving flow of water to the side outlet pipe with a water cushion, the design is simplified and bottom velocities in the flow are reduced.
