WATER INTAKE STRUCTURE Russian patent published in 2020 - IPC E02B9/04 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering for land reclamation purposes. Water intake structure includes water intake pipeline equipped with shutoff-control valves with water intake head arranged in channel in bottom water layer, equipped with a trash-and-fish protection screen (trash-bioprotection screen) in the form of a rigid body with a filtering mesh fabric and a pneumatic flushing device consisting of a system of air ducts equipped with nozzles. In order to increase efficiency, reliability and safety of water intake facility operation, the structure is equipped with two water-supplying pipelines operating alternately with water intake headers arranged on them, arranged on opposite sections of channel cross-section and consisting of trash-bioprotection screens. Trash-bioprotection screens are made in the form of a rigid hemispherical frame with a waterproof base. Base is coated with a filtering fine-meshed hemispherical water-receiving surface, in the cavity of which there is a flushing device, which air distributing tubular headers are equipped with different extended flexible nozzles with taking into account the shape of the sphere, directed towards the mesh fabric.

EFFECT: application of the device will allow to ensure continuous, stable and safe intake of water to be cleaned from garbage and biogenic contaminants from channels for its subsequent supply to drip irrigation systems.
