The invention relates to land reclamation and can be used to adjust and level the rice field checks.

A known rice irrigation system includes an open kart irrigator with a water level regulator in it. placed in the head of the channel, with water outlets into checks placed along the length of the channel, a check system and a waste open channel equipped with a headwater level regulator and outlets from checks {1 j.

However, elements of such an irrigation system cannot be used as automation tools, therefore, to ensure automatic control of the check level regime, it is necessary to create a special automatic control system.

Closest to the proposed closed rice irrigation system, including checks, head water intake, kart irrigator and card dumping, is located one below the other and hydraulically connected to each other, water discharge wells connected to the card dump by a check waste pipe, and water outlets 2.

The known system allows for the accelerated discharge of water from checks.

However, the ATA system does not provide for the adjustment of the level regime of checks from the place of the head intake, and also requires the creation of a special automatic control system.

The aim of the invention is to provide an automatic adjustment of the check level regimes from the place of the head intake.

The goal is achieved by the fact that each receipt waste pipeline at the outlet of the waste well is equipped with a water filled valve, the cavity of the second in the upper part is communicated by means of a supply pipe with an open sprinkler, and in the lower part there is a continuous discharge water outlet The feeding tube in the kart irrigator is equipped with a telescopic tube.

FIG. 1 shows a diagram of a rice irrigation system; in fig. 2 shows section A-A in FIG. one.

Rice irrigation system contains kart irrigator 1, equipped with water level regulator 2, powered from household irrigator 3, card reset 4, serving check system 5, node 6 of structures that regulate the level level of flooded checks of 1 mu, hydraulically connected as with map irrigator 1 with a card discharge 4, which freely discharges waste water into a household discharge 7. Checks 5 have water discharge wells 8 connected by a waste discharge pipe 9 to a card discharge 4. A check waste pipe rovod 9 at the outlet of the well 8 is provided with a relief vodonapoln emym valve 10, the cavity of which communicates with the Cartesian irrigator 1 feed tube 11, the telescopic pipe 12. okanchivayuscheys Vodonapoln emy valve 10 is provided at the bottom of the drain hole 13 a constant flow rate. In order to supply water in checks 5 on a kart irrigator 1, install float regulators 14 for water supply, communicated with checks of pipelines. House 15.

Rice irrigation system works as follows.

Water enters through the cart sprinkler 1 through regulator 2 from the household irrigator 3. When the water level in the cart irrigator I rises, water first of all

J passes through the telescopic pipe 12, feeds the pipe AND, and fills the valve 10. After filling the valve 10, the waste discharge pipeline 9 closes, so it is possible to supply water to the checks 5 in the process of further

0 raising the water level with a card sprinkler 1 through the water supply float regulator 14 and pipeline 15. When the check is filled, the water level in it rises to a predetermined level and pushes the water supply float regulator 14 to the specified

5 levels of water in the kartovy sprinkler 1, ensuring the water balance of the check.

If it is necessary to raise the water level in the checks, the water level in the irrigator 1 rises by the required amount, after

as the flow rate through the float regulator 14 increases, and consequently, the water level in the checks 5 rises together with the controller 14 to the mark at which the water balance is established.

If necessary, lower the level

5 in checks, the water level in the kart irrigator 1 is lowered; the water supply to the checks 5 is stopped and, consequently, the level of the four is reduced; a certain period of time due to constant loss of the node.

If it is necessary to discharge water from checks 5, the level in kart irrigator I is lowered below the telescopic bottom, 12, as a result of which valve 10 is depleted, residual water goes through the drain hole of constant flow 13 of valve 10. after that water. The water goes through the check waste pipe 9 to the card dump 4 and then to the household dump 7.

The use of rice irrigation system will provide improved operating conditions compared to izvesgnymi

as a result of automatic level control of checks from the place of head water intake and reduction of costs for automation of the system due to the conversion of the card irrigator into a control channel.
