Description

The invention relates to the field of agriculture and can be applied with the effective use of water resources on sloping and low-slope lands, drained by closed drainage.

There is a known drainage and humidification system (RU 2628341, 08.16.2017), which includes closed drains coupled with a collector communicating with a drainage drainage storage pond, on the bank of which a pumping station is located, connected through a fine water filter to a water distribution pipeline system associated with irrigation pipelines equipped with droppers-water outlets, while the fine water filter is a group of disc sprinklers installed above the filtration platform, including a waterproof corrugated base, on the surface of which a layer of filtering material is located, while a drainage groove is made along the contour of the site, connected to the tank for filtrate, equipped with a pump for supplying water to the drip irrigation system. Also, the filter material of this drying and humidification system can be peat mats.

The disadvantage of this system is the use of expensive drip irrigation, the use of which is carried out with a low seasonal load due to the use in areas of sufficient moisture, the filter materials used are also intended only for removing suspended solids from the water, however, the mineral composition of the waters of drained lands can negatively affect the operation of drippers.

Known drainage and humidification system (RU No. 2593530, 08/10/2016), including a water intake-water source, water supply and drainage collectors with wells equipped with automatic double-acting level regulators, a level regulator is installed at the outlet of the collector in the position of drainage regulation, while the well is divided a partition into two containers, in one of which a control membrane chamber is installed, and the second container is equipped with a weir elbow-shaped branch pipe having a valve on its outlet part, mechanically connected to the shoulder of the two-arm lever of the float level sensor, while the elbow-shaped branch pipe is rigidly fixed at the end of the channel by the inlet part communication with a valve with a control diaphragm chamber. Also, this drying and humidification system can be equipped with a control membrane chamber, which is communicated with the manifold mouth through a communication channel with a valve.

The disadvantage of this system is that when the system operates in the subsoil irrigation mode, the uniformity of soil moisture is not ensured both in the vertical and horizontal planes, which can affect the uniformity of the development of agricultural crops.

A known drainage and humidification system (RU 2608050, 10/12/2017), including a water intake-water source, water supply and drainage collectors with wells equipped with automatic double-acting level regulators, a level regulator is installed at the outlet of the collector in the position of drainage regulation, while the well is divided by a partition into two containers, in one of which a control membrane chamber is installed, and the second container is equipped with a weir elbow-shaped pipe having a valve at its outlet part, mechanically connected to the shoulder of the two-armed lever of the float level sensor, while the elbow-shaped pipe is rigidly fixed at the end of the communication channel by the inlet part with a valve with a control diaphragm chamber. Also, the control diaphragm chamber can be communicated with the manifold mouth through a communication channel with the valve.

The disadvantage of this system is its complexity in implementation, in particular, when a sprinkler system covers a large irrigation radius, it is necessary to build a well of significant size; with a decrease in the irrigation radius, the land use coefficient will decrease.

The closest system of the same purpose to the one declared in terms of a set of features is a drainage and humidification system with sprinkling (Handbook: Melioration and water management Drainage / Ed. By Academician of RAAS B.S. Maslov. - M .: "Association Ecost", 2001 - S. 337-338), taken as a prototype, including permanent or temporary humidifiers with a depth of 1 meter, cut through 120 meters, with a bottom slope of 0.0003-0.002. Field roads are laid along the humidifiers for the movement of sprinklers. The humidifier trails do not cross drains. Closed collectors are laid 50 cm deeper than the bottom of the humidification channels. The optimal length of humidifiers is 400 ... 800 m, which do not extend to the end of the irrigated area by 7 m.

The disadvantages of the known technical solution, taken as a prototype, is that in the presence of humidifiers cut through 120 meters and the field roads laid along them significantly reduce the coefficient of land use.

The objective of the invention is to create a constructive solution for a drainage and humidification system with a regulating capacity and irrigation by sprinkling machines with its own pumping and power units, designed to ensure maximum use of water resources through coordinated drainage and accumulation of drainage flow during wet periods and humidification of drained lands during dry periods, drainage and humidification network of which is hydraulically linked and allows the use of the regulating tank as a water source.

The technical result of the claimed invention is to ensure the drainage of the territory during the wet period and irrigation of crops during the dry season, and to increase the reliability and efficiency of the use of water resources (drainage flow) of the system.

The specified technical result is achieved due to the device of a drainage and humidification system on a slope-free land plot (low-slope) with a regulating tank made in the form of a storage pond, a regulation pool, etc. with combined humidification, including a crop rotation section with six fields and consists of 2nd order drainage collectors, a 1st order drainage collector, a closed combined drainage and humidification network for draining drainage water and supplying water to an open canal for a frontal circular intake (Fig. . 1) or a frontal (Fig. 2) sprinkler with its own pumping and power unit, characterized in that a non-sloping stationary sealed open sprinkler equipped with a wellhead structure with a regulator is provided, the length of which, when working with a front-circular sprinkler, is equal to the length of the field, with the exception of the length of the sprinkler and the reach of the end sprinkler. The design of the drainage and humidification system differs in that the length of the sprinkler when working with a front sprinkler is equal to the length of the field, with the exception of half the width of the sprinkler irrigation (the distance from the axis of the sprinkler pipeline to the boundary of the fall of extreme drops on the soil along the front).

The dehumidifying and humidifying system is illustrated in FIG. 1 and FIG. 2. In FIG. 1 - drainage and humidification system using a front-circular sprinkler. FIG. 2 - drainage and humidification system using a front sprinkler.

The drainage and humidification system includes the following elements (Fig. 1, 2): drains 1, drainage collectors of the 2nd order 2, drainage collector of the 1st order 3, open sprinkler 4, drainage and humidification pipeline 5, main drainage and humidification pipeline 6 , front-circular (Fig. 1) or frontal (Fig. 2) sprinkler 7, control center 8, chemicalization unit 9, water treatment unit 10, combined pumping station 11, water treatment unit 12, regulating tank 13, suction pipeline for water supply 14, regulating structures 15, retaining and regulating structure 16, water intake-water source 17, wellhead structures with regulators 18, wellhead structures with check valves 19. Arrows show the direction of movement of water resources: solid - outlet; dashed line - feed.

The dehumidifying and humidifying system works as follows. During the period of excessive humidification, water is collected along drains 1 and is transferred to the drainage collector of the 2nd order 2, then the 1st order 3 and the drainage and humidification pipeline 5, from where it enters the main drainage and humidification pipeline, whereby it enters the unit, if necessary water treatment 12 and then into the control tank 13. In case of overflow of the control tank, water is discharged into the water intake-water source 17.

During the period of insufficient humidification, water is taken from the control tank 13 by the combined pumping station 11 through the suction pipeline 14 and transferred through the main drainage and humidification pipeline 6 to the slope-free open sprinkler 4, from which the frontal-circular 7 (Fig. 1) or frontal 7 (Fig. 2) a sprinkler for the purpose of even distribution over the surface of the served land.

If there is an insufficient amount of drainage flow in the control tank 13, as well as the need to dilute the drainage flow with waters, water intake from the water intake 17 is provided.
