WATER INTAKE STRUCTURE Russian patent published in 2021 - IPC E02B9/04 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to the field of hydraulic engineering for the purposes of land reclamation. The water intake structure includes a water intake pipeline equipped with shut-off and control valves, combined with a mobile pumping station, taking water under pressure from a source for redistribution with adjustable valves of the pressure pipeline 2, equipped with water pipelines 5 with risers with closed pressure domes 10, and water is pumped through high-speed pressure with the organization of the jet movement of water under a rigid hemispherical frame 15 with a waterproof base 14. The base 14 of the silt-stop is covered with a filtering fine-mesh hemispherical surface 16, in the cavity of which a closed water intake dome 10 is located, consisting of modularly arranged side branches in the form of a bundle of tubes 11 along the height and along the perimeter of the intake dome 10, connected with the corresponding flow swirlers. The swirler of the water flow is each made in the form of a hyperboloid of rotation, where the pressure flow generates at a high speed and washes the inner surface of the sorboat in the form of a rigid hemispherical frame 15, covered with a fine-mesh filtering mesh fabric 16. A single flow swirling under pressure creates a single swirling flow of water and removes from the cavity continuously into a safe intake of water cleared of debris and biogenic pollutants from the canal for its subsequent supply to the drip irrigation systems. The swirlers of the water flow structurally consist of a hollow tube in the form of a hyperboloid of revolution, with separating blades-baffles, bent along the Archimedes spiral, located outside, to form a swirling flow. The channels themselves in the swirlers have a spiral shape and form a single swirling flow in the cavity of the trap-damper.

EFFECT: reduces material consumption, increasing the efficiency of jets coming out through a covered filtering fine-mesh mesh cloth, which will not only expand the functionality of the water intake structure, but also increase productivity during water intake, and also ensures its safe operation with a continuous stable intake of cleaned from debris and pollutants water.
