The invention relates to hydraulic engineering and can be used to collect water from mountain rivers for irrigation.

The purpose of the invention is to increase the efficiency of work by reducing the flow of sediment into the water intake chamber.

FIG. 1 shows a water intake (armament, top view; in Fig. 2 - a section on the firm.,

In the riverbed 1 of the river, retaining platform 2 was installed with an automatic water-supporting gate 3, which ensures the constancy of the water level C at the upstream 4 and the discharge of sediment into | downstream 5. The banks of the channel 6 of the channel 1 are adjacent to the overflow of thresholds 7, surrounding the banks of the river 6 and retaining equipment 2 water receiving chambers 8. k1 to the water receiving chambers 8 adjacent water receiving heads 9 with regulators 10 of the water flow, to which the discharge channels 11 are connected At each threshold 7, the stream-forming element 13 is rotatably mounted on o, bw, 12, and made in the form of horizontal segmented plumbing 14 with a window 15 and attached to the arcuate edge of the vertical arcuate shgastina 16. Element 13 o retracted by an arched plate 16 to retaining sruzheniyu 2.

Water intake works as follows.

: River flow saturated with sediments ps | The feed channel 1 enters the retaining structure 2, while the automatic water-assisting gate 3 creates the necessary water level above the overflow threshold 7, consequently, through element 13 the water clarified from the bottoms enters the water intake chamber 8, and from the latter into the receiving chamber 8. The current IT channel. Moreover, the channel stream, foray, onto plate 16, is divided into three streams. Upper brightened flow layer, deflected flat

16, enters the chamber 8, and at the same time the helical flow movement, which is squeezed out at the same time, contributes to the dropping of sediments to the window 15 and their sequential separation and pushing the threshold 7 from the wall to the central axis of the bed 1. Then the sediment transport is controlled through the span of the supporting structure 2 to the lower pool 5.

With flood expenses, when the flow and transport of sediment are dramatically increased along the channel, the span with gate 3 is completely open. Element 13 is rotated around the axis 12 by a drive into the water intake chamber 8, ensuring smooth passage of high sediment costs and additionally protecting the outflow channels 11 from sediment debris.
