I.ch () the brend belongs to o6.; Iacrn i andtechnology and can be used to regulate the water levels in the upstream of nonregional structures.

The purpose of the invention is new reliability and improved performance characteristics.

FIG. 1 and Fig. Shows level control, plan; in fig. 2 a section A-- L in FIG. ; (along Katia.iia); in fig. For, b - section B - B in FIG. 1 (but the main shutter); in fig. 4a, b section bb ia fig. 1 (but one of the chambers of the optional shutter).

The regulator contains a main channel 1, a trench 2 interfacing with a lateral branch 3 through a threshold 4, a retaining wall 5, a main gate 6, a wall in the form of a flat shield 7, connected with a console 9 installed on a horizontal axis 8 the weight of which is a counterweight 10. The regulator also contains an auxiliary shutter, the chamber of which is made of several chambers, for example

11 and 12. Each of the chambers 11 and 12 is formed by an additional flat shield 13, mounted on an axis of rotation 14, and a flexible element 15 connecting the free edge of the flat shield 13 to the concrete wall of the transt.

Chambers 11 and 12 are installed in series throughout the channel. The camera auxiliary shutter can be made of several cameras. The chamber adjacent to the main valve b, in this case chamber 11, communicates with the headwater of the main pipe 16, the plane of the outlet port of which is located parallel to the plane of the main gate 6 in the direction of flow and at a distance of 6 not exceeding the diameter of the main pipe 16 (Fig For, b). Camera

12 (FIG. 4) is communicated with the zone of influence of the chamber 11 by an auxiliary conduit 17. The chambers 1 and 12 contain washing boards 18. The position of the flat panel 13 and the flexible shell 15 forming the chamber 11, in FIG. 4a is shown by a dotted line.

The device works as follows.

The flow of water from the main, channel 1 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 into lateral discharge 3, and bottom sediment falls under the effect of the open main gate 8, 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.

With an increase in the water flow in the main channel 1, the main shutter 6 opens under the influence of an excess gap, begins to move the masses of water toward the opening, therefore the outflow of water from chamber 11 through the main pipeline Hi begins. The whole of this auxiliary valve will begin to descend below the level of water 1) () pool,

dropping izlinki water together with the fin to the downstream of the structure. With the achievement of NIITOM 13 of the camera 11 of the auxiliary shutter of a certain mark (Fig. 4a, b), it will begin to look at camera 12 of the auxiliary shutter through the auxiliary

the conduit 17, as a result of which the pressure in the chamber decreases, and the HUIT 13 of the chamber 12 will begin to descend following the shield 13 of the chamber 1 1, additionally dropping excess water into the downstream of the structure. With this in front

5, the main gate 6 maintains the estimated water head HP. which ensures the constancy of the overflowing layer of water over threshold 4. With a decrease in the flow rate of water in the main canal, the operation of the device is repeated in the reverse order.

0 The effectiveness of the device lies in the fact that it allows you to block wide river beds, canals, maintain a constant water level in them, fight against sediment and fin. The gates come into operation alternately, i.e. at first, the main shutter opens, which then puts into operation a nearby camera, which introduces a sequentially installed camera, last puts the next one into operation, etc. in the case of a multi-span structure. Such a scheme of operation allows one to discharge excess costs concentrated, i.e., if the water flow rate corresponds to the capacity of the main gate and the auxiliary gate adjacent to the non-camera, then subsequent cameras will not open (lower), which increases the reliability of the whole structure. If instead of a few chambers of the auxiliary shutter there is one camera of length, then the same flow rate will be discharged in a thin layer. This prevents the fin from moving to the lower section of the structure, in addition, the auxiliary logger is under considerable loads and transfers them to the supporting elements of the structure, which complicates

, design execution.

The proposed device can also be used to adjust the level in the downstream structure. To do this, you need to replace the main gate of the upstream level regulator with the lower level regulator

0 pool, which will control the auxiliary gate by perturbation from the downstream structure, maintaining the constancy of the level in the downstream.
