Description

(54) SEGMENT SHUTTER OF HYDROTECHNICAL STRUCTURE

12. This chamber receives water through pipeline 13, at the inlet 14 of which a garbage truck is installed (a grid is not shown). The outlet 15 of pipeline 13 g is covered by a movable valve 16 mounted on lever 17, pumped on support 18 under the action of the float-sensor 19 water level downstream ,. The latter is attached to the rod 20, moving | Q along the heights © to change the installation of a predetermined water level of the downstream. The rod 2O is fixed in the desired position by clamp 21 on the lever 17. Above the float-sensor 19 on the rod 20 there is a cylindrical jg tank 22 without a lid, in the bottom 23 of the tank there is a drain -: calibrated opening 24. Above the tank 22, sleeve 25 is located behind the vine 25, connected by an inlet pipe 26 with an inlet 27, moving with a rod 28 and with a fastened clamp 29 at the mark of the maximum allowable water level of the upstream. The volume of the container 22 is chosen so that when it is filled with water, the float sensor 19 is submerged under the water level in the chamber 9. The size of the calibrated holes 12 and 24 is set so that the water flow through them is much less than the possible flow, respectively, through the pipeline 13 with the hole open 15 and through line 26 at the headwater level at a level higher than the maximum allowed. Before starting the shutter operation, the counter balance 5 is loaded so that the shield 1 is at any of the working positions in equilibrium with the water level in the KaMepfe 8 float at water elevations approximately 5–15 cm above the maximum lower water level of the downstream. in a way.

With the upstream water levels lower than the maximum allowable mark, and with the downstream water level equal to the given shield 1, it is in a state of dynamic equilibrium. At the same time, the float is 50 sensor 19 with the help of the lever 17 and the movement of the valve 16 opens the outlet 15 so that the flow of water into the float chamber 8 through this opening

equal to the outflow of water Through a calibrated g-55 bay.

Aergy 12. In the chamber of the 8th level, the WATER is located at the mark between the water level of the upstream and the water level of the downstream of the structure. With an increase in the level of WATER of the downstream of the water in the chamber 9, the water level also raises the float-sensor 19 and the lever 17 additionally lifts the shade to open the outlet 15. water level and the necessary for restoring a given horizon-vdda: downstream cover of the shield 1 under the action of the increased churning. Segmental valve of the hydraulic structure according to the auth St. No. 424945, characterized in that, in order to ensure the possibility of a mixed control of the upper and lower pools of the structure, a container made with a suction opening on the stem of the float sensor is connected by means of a pipeline to the top of the float 2. The lower water level and the downstream water level of the target system are working in a brotherly direction, eliminating the resulting coordination. In the case when the water level of the upper pool reaches and begins to exceed the maximum allowable, water through the inlet port 27s supply line 26 and the sling sleeve 25 enters the tank 22e. Under the influence of the weight of water in 22, the lever 17 attaches the outlet 15 to the movable valve 16 so that the water level in the float chamber 8 decreases and the shield 1 opens to the extent necessary automatically maintaining the level L Vod headwater at the level not higher maksymapygo permissible. This happens regardless of the downstream water level. By reducing the water level of the upstream below the maximum allowable mark, the system proceeds to autoregulate the set downwater level. formula of invention
