The invention relates to hydraulic engineering in the design of canals and the operation of irrigation systems.

The aim of the invention is eco-friendly. irrigation water, reduction of canal construction and improvement of irrigation systems operation.

Figure 1 shows a controller; in FIG. 2, the same% view of the top,

The regulator contains the channel of channel 1, the shutter 2 installed in the latter and the weir 3, made in the form of a sideway with respect to the drain gate, the drain edge of which is located below the level of the maximum opening of the shutter at the level specified.

At the outlet of the side spillway, a spillway pipe 4, which provides the discharge of water from the design channel 1 to the area of the intersected channel 5, is installed,

The shutter is installed on the wall of the partition 6, installed across the project channel 5.

Spillway 3 is formed by at least two lateral taps, expanding

. on both sides of the gate, and the edge of the weir is located along the channel axis.

The device works in the following 5 ways.

During the operation of the regulator, water enters the channel, where, spreading and filling it, the flow rate at the approach to the upper level is less.

0 by the structure. As the upper pool is filled, water flows through the gate-controlled opening to the lower pool. With increasing channel flow rate the water level before the shutter

5 increases to the target level, at the level of which the drain edge of the two weirs 3 is located. A further increase in the flow rate and, as a result,. The reduction-level leads to an automatic symmetrical overflow of fluid through the drain edges of the water-j drains into the spillway chambers, and of them through the overflow pipes 4 - into the intersected channel 5.

In the emergency position of the regulator, the shutter 2 is closed and its operation is similar to that described, but no water enters the lower reach.

Claims (3)

1. LEVEL REGULATOR IN IRRIGATING CHANNELS, containing a shutter and a spillway installed in the channel bed, characterized in that, in order to save irrigation water, reduce the volume of canal construction and improve the operation of irrigation systems, the spillway of the regulator is made in the form of a lateral drain outlet relative to the shutter, the drain edge of which is located below the level of maximum opening of the shutter at the level of the set level, and an overflow pipe is installed at the outlet of the spillway. 2. The controller according to claim 1, characterized in that the spillway is formed by at least two lateral branches located on both sides of the shutter. § 3. The regulator according to claims 1 and 2, characterized in that the edge of the spillway is located along the axis of the channel. SU ,,,. 1174906 Figure 1
