Description

The system of automatic drip irrigation of plants refers to irrigation systems and is intended for the organization of automatic irrigation of many plants.

A device for automatic watering of plants is known (patent RU No. 2539854 dated 09/10/2013), comprising a container for irrigation liquid with a device for supplying irrigation liquid to several rows of plants, having an output hose connected to a pump with a feeding tip, a drive for moving the tip controlled by a software device branch pipes located at each plant row, to which distribution pipelines with watering tips are attached. The software device automatically controls the process of watering the plants.

The disadvantage of this device is significant fluctuations in soil moisture as a result of intermittent irrigation due to the movement of the irrigation hose with a tip from one receiving pipe with a distribution pipe to another.

A known plant watering system (patent RU No. 2331189 dated 09/04/2006), containing a receiving tank for water, a feeding tube, a siphon with a trigger mechanism, a hydraulic channel in communication with the siphon, is connected via a splitter to a distribution pipe for watering plants, the ends of which are equipped with droppers. The siphon trigger mechanism contains a hydraulic pump, which is installed at the bottom of the receiving tank and is equipped with an electronic starting device (EPU) with a programmer and a photoelectric sensor. EPU is configured to automatically control the process of watering plants according to a given program.

The disadvantage of this system is the slow flow of fluid through the siphon after turning off the pump, which can lead to a lack of moisture in the soil, as well as the lack of automatic maintenance of the moisture level necessary for optimal plant growth.

Known soil moisture sensor (http://iarduino.ru/shop/Sensory-Datchiki/datchik-vlazhnosti-pochvy.html), connected to the control electronics, having analog and digital outputs.

The technical problem solved by the utility model is maintaining a given level of soil moisture with a minimum consumption of electricity from the network.

The technical problem is solved in an automatic drip irrigation system for many plants planted in parallel rows in the ground, including:

- irrigation subsystem, consisting of:

- containers with water installed near the rows of many plants;

- a pump with an electric drive, located inside the tank with water, having a suction and discharge nozzles;

- a pressure hose connected to the discharge pipe of the pump;

- a main splitter connected to the pressure hose to which several distribution hose lines are connected, each with a plurality of secondary splitters connecting the distribution hoses in series; each of the secondary splitters has additional nozzles;

- a plurality of feed hoses connecting a plurality of droppers to a plurality of additional nozzles;

- many droppers in the form of tubular pins buried near the roots of plants with holes for drip water supply;

- plugs plugging each last distribution hose or pipe of the last secondary splitter,

- a power supply subsystem having an electric power source connected to an electric drive;

- a drive control subsystem having a programmable controller connected to an electric motor,

wherein

- in the power supply subsystem, the source of electricity is a solar battery with an electric battery connected to it;

- in the electric drive control subsystem, the electric motor has a microprocessor connected to the controller by an interface bus, and in the soil between the irrigated plants in each row there is at least one soil moisture sensor connected by an interface bus to the controller.

Each secondary splitter of the irrigation subsystem has two additional nozzles, while the length of one of the feed hoses corresponds to the distance between adjacent rows of many plants.

The distance between each pair of irrigated rows of many plants is greater than between the rows of plants in a pair.

The irrigation subsystem has a device for maintaining the water level in the tank.

This combination of distinctive features was not found in the process of patent information search, therefore, the utility model meets the criterion of "novelty."

In FIG. 1 shows a system of automatic drip irrigation of plants in the soil of a greenhouse.

In FIG. 2 - a system of automatic drip irrigation of plants in open ground.

The system of automatic drip irrigation of many plants 1 (Fig. 1, 2), planted in greenhouse soil (Fig. 1) or in open ground (Fig. 2) in parallel rows 2, includes:

- irrigation subsystem 3, consisting of:

- tanks 4 with water installed near rows 2;

- a pump 5 with an electric drive 6, located inside the tank 4 with water, having a suction pipe 7 and a discharge pipe 8;

- pressure hose 9 connected to the discharge pipe 8;

- the main splitter 10 connected to the pressure hose 9, to which several lines 11 of the distribution hoses 12 are connected, each with a plurality of secondary splitters 13 connecting the distribution hoses 12 in series; each of the secondary splitters 13 has additional nozzles 14 (Fig. 1) with a plurality of feed hoses 15 connecting a plurality of droppers 16 buried near the roots of plants 1 in the form of tubular pins with holes 17 for drip water supply with a plurality of additional nozzles 14;

- plugs 18 plugging each last distribution hose 12a or pipe 14a of the last secondary splitter 13a;

- a power supply subsystem 19 having an electric power source in the form of a solar battery 20 with an electric battery 21 connected thereto, connected to an electric drive 6;

- a control subsystem 22 of the electric drive 6 having a programmable controller 23 connected to the electric drive 6, the electric motor 24 of which has a microprocessor 25 connected to the controller 23 by an interface bus 26, and at least one in the soil between the irrigated plants 1 in each row 2 a soil moisture sensor 27 connected by an interface bus 28 to a controller 23.

The program in the programmable controller 23 sets the range of the controlled soil moisture level. For example, the manufacturer of the “DFRobot” Arduino-based soil moisture sensor 27 suggests interpreting its readings as follows:

"0-300: dry;

300-700: wet;

700-950: in the water. "

Each secondary splitter 13 of the irrigation subsystem 3 may have two additional nozzles 14 (Fig. 1), while the length of one of the supply hoses 15 corresponds to the distance between adjacent rows 2a and 2b of many plants 1.

For the convenience of processing plants 1 and picking fruits, the distance 29 between pairs 30 of irrigated rows 2 of a plurality of plants 1 is greater than the distance 31 between rows 2a and 2b of plants 1 in a pair.

Watering subsystem 3 may have a device (not shown) for maintaining the water level in the tank 4.

The operation of the automatic drip irrigation system is as follows. Programmable controller 23, having received a signal about the level of soil moisture from the sensors 27 through the interface bus 26, gives a signal to turn on or off the electric drive 6.

When the electric drive 6 is turned on, the pump 5 connected to the electric accumulator 21 pumps water from the tank 4 into the pressure hose 9. The pump 5 operates in accordance with the program selected on the programmable controller 23. The electric battery 21 of the controller 23 is charged with electric energy from the solar battery 20, and in the absence of sunlight - from a household electrical network (not shown).

The water flow in the pressure hose 9 using the main splitter 10 is divided into two or three lines 11, depending on the planting pattern of many plants 1. If only two lines 11 are needed, the third nozzle 10a (Fig. 1) of the main splitter 10 is closed with a stopper 18a.

Through the secondary splitters 13 of the irrigation subsystem 3, water is supplied through a plurality of feed hoses 15 and a plurality of droppers 16 directly to the roots of plants 1.
