The invention relates to hydraulic engineering and can be used to maintain the water level in the channel in the blocking structures,

The purpose of the invention is to increase the reliability and increase the capacity of the controller.

FIG. 1 shows a regulator, a plan view; in fig. 2-4 shows section A-A in FIG. 1 (various moments of the regulator); in fig. 5 is a section BB in FIG. one; in fig. 6 and 7 -regulator, general view.

The regulator contains the main channel 1, the trench 2, which mates with the lateral branch 3 through the threshold 4, the sampling wall 5, the main gate

6, made in the form of a flat shield

7 connected to a non-horizontally mounted rotation axis 8 by a console 9 on which a weight counterweight 10 ... is attached. The controller also contains an auxiliary gate with several cameras, for example 11 and 12. Each chamber is formed by an additional flat shield 13 mounted on

the axis of rotation 14, and the flexible element 15 connecting the free edge of the flat panel 13 to the concrete wall of the trench.

Chambers 11 and 12 are installed in series over the entire width of the channel, the chamber closest to the main gate 6, in this case chamber 11, communicates with the headstream of the main pipe 16, the plane of the outlet port of which is parallel to the plane of the main gate 6 in the direction of flow the distance if is not greater than the diameter of the main pipeline 16. Chamber 12 is in communication with the zone of influence of chamber 11 by an auxiliary pipeline 17. Chamber 11 and 12 contain washing boards 18.

In addition, the regulator additionally contains bottom flushers 19 and 20, made in the form of short pipelines passing through chambers 11 and 12. Washbasin 19 passes through chambers 11, and washer 20 through chambers 12, i.e. In each chamber of the auxiliary gate there can be one two or more industrial sites depending on the length of each chamber and the superficial regime of the river. The bottom industrial outputs 19 and 20 on the downstream side overlap with valves 21

and 22, rigidly connected to additional flat shields 13. Moreover, each valve 21 and 22 have a weight counterweight 23 fixed on the console 24.

The device works as follows.

The water flow from the main channel enters trench 2 and, having received a rotational-translational motion, moves to threshold 4. The more clarified part of the stream (without sediment) overflows through the threshold, enters lateral discharge 3, and bottom sediment is affected by an open main gate 6, creating bottom currents, is transported to the downstream of the structure. The fin is dropped into the downstream of the structure through chambers 11 and 12.

The main shutter 6 and the auxiliary shutter consisting of the chambers 11 and 12 operate as follows.

As the water flow in the main channel 1 increases, the main shutter 6 under the influence of excess water pressure opens, the mass of water begins to move toward the hole that has formed, subsequently, the outflow of water from chamber 11 through the main pipe 16 begins. As a result, the auxiliary shutter begins to fall below the level the waters of the upper reach, dropping excess water together with the fin to the lower reach of the structure, simultaneously moving upward the valve 21 (Fig. 3) together with the counterweight 23 and opening the bottom bottom 19, which contributes to the discharge into the downstream of bottom water layers saturated with bottom sediments. When the shield 13 of the auxiliary shutter chamber 11 reaches a certain mark (see Fig. 3), its influence on the auxiliary shutter chamber 12 through the auxiliary pipeline 17 begins, as a result of which the pressure in the chamber decreases and the shield 13 of the chamber 12 begins to descend after the shield 13 of the chamber 11, additionally discharging excess water into the downstream of the structure and at the same time opening the bottom washer 20 by moving the valve 22 with the load balance 23 upwards. This provides an additional discharge of water from the bottom layers along with the bottom and pumps. This moment Ustronstpl work shown
