Abstract

The invention relates to hydraulic engineering and can be used to control the flow of water supplied to the discharge channels on the water distribution nodes of irrigation systems. The purpose of the invention is to increase the operating efficiency when installed in a water distribution structure by increasing throughput. The shutter-stabilizer is made in the form of a rectangular wall 11, a stepped wall 13 and ribs 15 located between them. Walls 11 and 13 have a visor 12 and a curved tip 14 in the lower part, respectively. The stabilizer gate has a vertical movement actuator 10 and a actuator 19 of a valve 18 installed by means of a hinge 17 on the edge of the plate 16. The actuator 19 is made of a cable. When the valve 18 is raised, the device acts as a water flow stabilizer. Depending on the level of water in front of the stabilizer gate, the number of working steps of wall 13 varies, which changes the flow of water between walls 11 and 13, and consequently, the flow of water through the structure. With the valve 18 lowered, the device allows an increase in the water flow passing through the gate stabilizer. 3 il.

Description

The invention relates to hydraulic engineering and can be used to control the flow of water supplied to the outlet channels at the water distribution nodes of the structures of irrigation systems.

The purpose of the invention is to increase the operating efficiency when installed in a water distribution facility by increasing throughput.

Figure 1 shows the water distribution unit of the irrigation system, top view; figure 2 - section a - a in figure 1; in Fig.3 is a view of B in Fig.2.

The stabilizer gates 1 and 2 are installed in a water distribution unit with a supply channel 3, outlet channels 4 and 5 and a transit channel 6 between them, having a separation head 7 and two weirs 8 and 9 at the head.

Shutter-stabilizers 1 and 2 contain a box-shaped shield with an actuator 10, made in the form of a rectangular rear wall 11 with a horizontal visor 12 in the lower part, a stepped front wall 13 with a curved head 14 in the lower part and transverse vertical ribs 15 located between the walls 11 and 13 along the borders of the steps. A horizontal plate 16 is attached to the upper part of the wall 11 by the edge, with a width equal to the thickness of the box shield, to the free edge of which, by means of a hinge 17, a flat valve 18 is connected, connected to a cable actuator 19 located on the wall 11.

When the valve 18 is raised by the actuator 19, the gate-stabilizer 1 operates in the stabilization mode. Depending on the change in the water level in front of the shutter-stabilizer 1, a different number of steps are involved in the work, between the walls 11 and 13 a different flow rate of water passes, preventing the flow of water under the head 14, which ensures the constancy of the flow of water passing through the device. When the valve 18 is lowered, the shutter-stabilizer 1 acts as a flat shield, providing large waste water consumption. Depending on the height of the stabilizer valves 1 and 2 έ the composition of the water distribution unit (figure 1), you can adjust the water flow in the channels 4,5 and 6 from maximum to zero, i
