Description

The invention relates to hydraulic engineering and can be used for dividing the flow of water in irrigation canals with a steady flow regime.

A water distributor for channels is known, which consists of supply, transit and discharge channels, gates on the transit and discharge channels, and a differential made in the form of a water well 1.

The disadvantage of this structure consists in the difficulty of stabilizing the flow of water in the outflow channels, since for this it is necessary to constantly maneuver the closures of the outflow channels in case of changes in the flow rate of the water in the supply channel.

A water distributor for channels is also known, comprising a supply channel, a well located at the end of the supply channel, a transit channel connected to the well, discharge channels arranged in the side walls of the well at the bottom of the supply channel, and a device for directing flow diverting channels 2.

In the known water distributor, the device for directing the flow to the discharge channels is made in the form of a complex rotary metal structure with a plurality of elements, which has a low accuracy in stabilizing the flow of water in the discharge channels.

The purpose of the invention is to simplify the design, increase the reliability of operation and the accuracy of stabilizing the flow of water in the discharge channels.

The goal is achieved by the fact that in a water distributor for canals containing a supply channel, a well located at the end of the supply channel, a transit channel connected to the well, outlet channels made in the side walls of the well at the bottom of the supply channel, and the device for directing the flow to the discharge channels, the device for directing the flow to the discharge channels is made in the form of a T-shaped tray in plan, the ends of which are connected to the feed and discharge channels.

The upper edges of the tray are located at the level of the minimum filling of the supply channel, and the bottom - at the level of the bottom of the supply channel.

The water distributor is equipped with valves, which are located in the outlet channels.

FIG. 1 shows a water dispenser, top view; in fig. 2 shows section A-A in FIG. one.

Water distribution for canals consists of supply I, transit 2 and outlet 3 channels, water supply tray 4 T-shaped in terms of shape, valves 5j

 located in the outlet channels 3, and the well 6, located at the end of the inlet channel 1. The transit channel 2 adjoins the well 6, and the outlet channels 3 are made in the side walls of the well 6,

5 at the bottom of the feed channel 1. Tray 4 is a device for directing flow into the discharge channels 3 and its ends are connected to the feed 1 and discharge 3 channels. The upper edges of the tray 4 are located at the level of the minimum filling of the supply channel 1, and the bottom - at the level of the bottom of the supply channel 1.

Water dispenser works as follows.

The water from channel 1 enters tray 4,

5 from there to its branches and from them to the discharge channels 3. If there is more water flow in the supply channel 1 than is required in the discharge channels 3, water flows through the edges of the walls of the tray 4 into the well b and enter the transit channel 2. Thus, a constant flow of water is supplied to the discharge channels 3, and the surplus is discharged into the transit channel 2.

Such an embodiment of the water distributor allows for the automatic maintenance of a constant water level in front of the gates of the diverting channels and, therefore, stabilizing the diverted water flow; due to the elongated front of the spillway (through the walls of the T-shaped tray in terms of shape) to ensure the unhindered discharge of increased water flow into the transit canal, which eliminates emergency situations at the structure; to ensure the compactness of the structure due to the fact that the well is located within the water distribution unit (under the T-shaped tray), and not behind the structure; ensure simplicity of design and reliability in operation; and also eliminate the need to equip the transit channel with a gate.
