WATER INTAKE STRUCTURE Russian patent published in 2018 - IPC E02B9/04 E03B3/04 E03B3/36 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to hydraulic engineering and can be used to draw water directly from the surface channel of the watercourse, the water of which contains a large number of deposits and debris, as well as water intake into canals, pipes and pumping stations of pumping stations. Water intake structure contains installed ladle water intake chamber 1 in the channel of watercourse 2. Input of the water intake chamber 1 is equipped at an angle by protective grate 6, drain 4 with a wide threshold with operational shutter 5, and the outlet is intake chamber 3 connected to discharge channels 9 and 10 with flow regulators 11 and 12. Protective grate 6 is supported by a free end on step 7. Transverse baffle 13 in the form of a rigid curvilinear wall fixed at the bottom of the channel of watercourse 2, and separating vertical wall 14 located parallel to the coastal edge of the channel of watercourse 2 forms flow channel 15 from the side of water intake chamber 1. Elements 13 and 14 contribute to the release of sediments towards the outlet of section 16 into the channel of watercourse 2 and the flow of clarified water into intake chamber 3. Hydraulic jet is formed below the ladle water intake chamber 1, and the flow of water to the consumer is taken through a weir 4 with a wide threshold. Marks of the bottom of intake chamber 3 and the channel of watercourse 2 do not coincide, as a result, a given intake of water takes place. At the top of elements 1, 6 13, 14, overlap 17 is installed.

EFFECT: invention makes it possible to create hydraulic conditions in the zone of influence of water intake, providing effective protection against deposits and debris during water intake, simplification and reduction of metal consumption.
