Description

one

The invention relates to meliora-open irrigation systems and allows land irrigation to be performed during group operation of wide-area Kuban irrigation machines.

The aim of the invention is to improve the performance of the system by ensuring its reliability and the rational use of irrigation water.

The drawing shows schematically the proposed irrigation system.

The irrigation system contains a distribution channel of 1 T-shaped view (in plan) with a two-way flow regulator 2 in its head part. At a distance

in addition to the last 7th channels, their flow controllers 9 with distribution channel 1 or its branches 6 are lower than the upstream level regulator 8 that is closest to this irrigation canal. The system works in the mode of group work of wide-spanning, Kuban-type sprinkling machines.

When a sprinkler is put into operation, for example, at the extreme channel 7, water flows through the distribution channel 1 in transit through the river; tors 8, since after filling the irrigation channels 3 and 4, the water through the channels 10 is discharged again into the distribution channel. First, the average irrigation channel 5 is filled, then the remaining channels 5. In the case of a sprinkler machine disconnecting on channel 7, the branch 6 of the distribution channel begins to overflow, and the flow rate is adjusted by means of controllers 8 and 2 of double-sided operation.

If another machine is switched on, for example in channel 5, the volume of water, on the other hand, in channel 5, will start to operate. Previously discharged through regulator 8, the minimum transit flow will begin to flow into channel 5.

After the estimated time, the flow controller 2 will operate and the water flow will increase. Corrector V. Sinitska Subscription
