Description

The invention relates to agriculture and can be used for automated irrigation and water distribution in rice irrigation systems.

The aim of the invention is to reduce the capital cost of laying cable lines.

The drawing shows a diagram of an automated rice irrigation system.

The system contains an irrigation source 1, a main channel with a head automated water intake structure 2 and a dispatch center, a distribution and irrigation channel 3. The main channel is equipped with blocking structures with downstream regulators A. Water outlets 5 to the irrigation canals and rice paddies, as well as water outlets 6 to the distribution pipelines are equipped with lowwater level hydraulic machines. The system also contains damping rice checks 7, equipped with hydraulic automatic machines of the 8th level of combined action with upstream and downstream controls.

Damper rice checks 7 form a damper field, the outlet to the distribution channel of which is reinforced with a 9-level hydraulic automatic machine and a flow meter 10, which is connected to line 11 with an automated water intake structure 2.

The system works as follows.

In accordance with the water consumption forecast for the next control time interval, the automated water intake structure supplies the specified irrigation flow to the rice irrigation system. Due to the fact that water outlets in rice fields, irrigation canals and distribution channels, as well as the blocking facilities of the main canal, are equipped with hydraulic automatic level 4 and 6

the pool, they take water of exactly as much as 50 downstream at the entrances to the distribution, how much is needed to compensate for the loss of transpiration and filtration. At the same time, all the excess or deficiency of WATER is in the first bay of the main canal, closest to the automated water intake structure 2. The excess or deficiency of water through the hydraulic automatic 9 level headwater and flow meter 10 enters

 S

spr; The distribution pipeline of damping checks 7 and further through hydraulic automatic machines 8 of mixed action into damper rice checks 7, which are used as reserve adjustment volumes within the required accuracy of maintaining a level of 2 cm from the nominal value. With

This automatically corrects the flow rate of the automated water intake facility by uQ, determined by the formula

. ““ -

where Q - the actual flow rate of water entering the outlet, regulated on the upstream;

QP is the predicted discharge of water entering the outflow regulated by the upstream pool;

S is the total area of the rice system;

Sj is the area of the rice system on which the downstream regulation is performed.

The flow rate Q is measured by the flow meter 10 and transmitted via the communication line 11 to the automated water intake structure 2, where the water supply flow to the system is calculated and corrected.

The application of the proposed system will significantly (5-10 times) reduce the consumption of cable products for automating the processes of water distribution and irrigation.
