Description

The invention relates to hydraulic engineering, in particular to the automatic regulation of water levels in rivers and other streams by a cascade of hydraulic structures, and can be used mainly in land-reclamation systems.

The purpose of the invention is to increase the speed of the system.

Fig. 1 schematically shows the control system, a section along the axis of the water course; figure 2 - node I in figure 1.

The control system contains an automatic water level controller for the upper and lower pools, having a water-filled float 1, which is placed below the water level of the upper pool, on each of the NMHs of the structures blocking the water flow. The water-filled float 1 of the regulator on the building 2, located downstream (downstream), is connected to the regulating body in the form of a pressure head SCHITa 3 by means of a rotary double-arm lever 4 (can be rotated about the horizontal axis 5). The pressure shield 3 closes the culvert 6 on the downstream side of the structure 2. The water-filled float 1 is connected to the atmosphere with a tube 7, with the upper reach - an opening 8 with a filter to prevent litter from the water flow from entering the float, and with a downstream by means of flexible water supply tube 9, having a greater culvert capacity than the hole 8.

The outlet of the flexible water pipe 9 is placed in the chamber 10 connected by pipe 11 with the lower pool, and attached to the support 12 through the pull 13 and the end cap 14 of the tube. On the vertical outlet pipe of the flexible water pipe 9 there is a valve made in the form of a suction outlet pipe of the flexible water pipe 9 of the annular float 15 fixed with a shear limited by the plug 14 and the stop 16, and blocked by the annular float 15 of symmetrically arranged discharge openings 17, made in the outlet pipe of the flexible tube 9. A water-filled float 18 of the regulator on the overlying

The structure 19 is provided with an additional water pipe 20, the output end of which is connected and connected to the outlet of the flexible water pipe 21 of the regulator of the underlying structure 2.

The total water permeability of the discharge holes 17 is not less

0 than the total water throughput capacity of pipes 9 and 20. The inlet pipe of the additional water pipe 20 is connected to the flexible water pipe 21 of the upstream regulator

5 of the structure 19. To the flexible water pipe 21 an additional water pipe 22 of the structure regulator, which is located higher than the structure 19, is connected. Valve

0 on the outlet pipe of the flexible water pipe 21 is made similar to the valve on the outlet pipe of the flexible water pipe 9. At the same time, the total water throughput is

5 blocked by an annular float 15 consumables, the holes 17 in the flexible water pipe 21 are not less than the total capacity of the pipes 21 and 22, the total capacity of the pipes

0 the capacity of the tubes 20 and 21 is greater than the water carrying capacity of the hole 23, which connects the water-filled float 18 to the upper side of the structure 19, and each of the tubes 20 and 21 separately has a lower water-carrying capacity than the hole 23. The pressure shield 24 is connected to the water-filled float 18 Behind Building 2 is a lower pool 25.

0 The system works as follows.

With an increase in water intake from. The section of the watercourse is low (downstream) of the structure 2, the water level in its lower pool falls and the annular float 15 is lowered, following the level along the flexible water pipe 9 and covers the supply holes 17 in it. As a result, both of the double-level float 1 and and of

Similarly to the completed water-filled float 18 of the automatic regulator of the overlying structure 19, less water flows out than it enters the float through the opening 8 or a similar opening 23, and both floats are filled with water.

Filling the water-filled float 1 causes the shield to turn 3

(together with the float) at a greater angle of its opening, thereby increasing the flow of water through the culvert 6 from the top to the downstream of the structure 2. At the same time, the same process opens the porch 24 connected to the water-filled 18, which increases the flow through the culvert opening 26 of the overlying structure 19 and replenishment of the reserve volume of water in the area between the constructions 2 and 19, triggered through the culvert opening 6,

When water consumption decreases, level 25 rises, and the ring float 15 follows the level that

The automatic regulator, cw 19, with a water pipe 22, ensures the operation of the next section in the cascade, downstream.

Claims (2)

1. A water level control system in the pools of a cascade of hydraulic structures on a watercourse containing automatic level controllers installed on structures with a water-filled float in the upstream side, connected to a regulator mounted on the culvert, the float cavity communicates with the atmosphere and results in the opening of consumable openings 2o by the downstream tail of the flexible water piping 17, the simultaneous outflow through the tube, on the outlet branch pipe 15 they are water from water-filled floats 1 and 18, covering the shields 3 and 24, which reduces the water flow through the holes 6 and 26. With an increase in water intake from the section of water current between structures. 2 and 19 (with openings of the x 17 tube 9) water level in the downstream of structure 19 falls, and the holes in the water pipe 21 overlap with an annular float 15. This leads to the filling of water with the water-filled float 18, since the outflow of water from the latter through pipe 20 (with the pipe 21 blocked) is less than the flow of water into the water-filled float 18 through the opening 23, to the opening of the shield 24 and to an increase in the flow of water through the opening 26 from the upper to the lower pool of the structure 19. Thus, the automatic controller of the structure 19 operates in this case regardless of the position of the water level lower its underlying pond construction applications 2.
