DAMLESS WATER INTAKE FOR MOUNTAIN RIVERS Russian patent published in 2017 - IPC E02B9/04 

FIELD: construction.

SUBSTANCE: damless water intake on a mountain river 1 consists of the water intake device 2 with the head part 3, the straight dam portion 4 with the walled sleeve 5, in which the short end of the intake device 2 extends, with an opening for discharging excess water 6, the bolt 7 for flushing sediment, the dam portion 8 for coastal protection, the dam portion 9 rolling into the bank of the channel 10, the water intake device pocket 11 formed by the partition 12, and rolling into the other bank 14 of the channel 10, the threshold 13 of the pocket, the support flap 15, and the lifting mechanism 16. The intake of the upper water layers from the river 1 is provided by the device 2 with the head part 3, the short pipeline side of the device 2 passes through the sleeve 5 walled in the body of the dam 4. In the case of accumulation in the pocket 11 from the suspended sludge particles and sediments at the threshold 13, they are washed off by means of opening the valve 7. The device for water intake from the river is equipped with the support flap 15 also serving as a hydrofoil for emergency ejection, and the mechanism 16 for lifting it out of the river in case of high water or a large mud flow.

EFFECT: excluding the bottom sediments inflow, reducing the amount of suspended solid sediments.
