Description

A device for automatic watering of plants refers to irrigation systems and is intended to organize automatic watering of a group of plants.

A device for watering plants [1], containing a receiving tank with a supply liquid, a pump made with inlet and outlet pipes, the end of the inlet pipe is lowered into the tank, and the outlet pipe from the pump is connected to the soil with the function of watering plants, also containing a sensor humidity, photoelectric sensor, communication device, controller, while the pump is configured to start from the controller, while the controller is configured to automatically control the process of watering plants for Anna program.

The disadvantage of the design of this device is that it is applicable only for watering a single plant.

Also known is a plant watering system [2], containing a receiving tank for water, a feeding tube, a siphon with a trigger mechanism, a suction elbow and a sensor tube connected to the atmosphere, a hydraulic channel in communication with the siphon, and a distribution pipe for watering the plants. The feed tube is equipped with a metering valve with a locking device, and the siphon is made in the form of a tee with two inlet nozzles and one or two outlet nozzles, while one inlet nozzle is connected via a hose to the siphon trigger mechanism, the other to the sensor tube, and the outlet nozzle is to the hydraulic channel, which through a splitter connected to the distribution pipe for watering plants. The ends of the distribution pipe are provided 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.

This system provides group watering of plants, but is of little use for watering indoor plants due to the cumbersome design and specific requirements for installing the trigger mechanism of the siphon. In addition, it is difficult to regulate a single volume of watering in it, once watering has already been started, it will end only after all the liquid has been poured out of the tank.

The closest in technical essence and the achieved result is a plant watering system [3], containing a tank for irrigation liquid, a device for supplying irrigation liquid, the input of which is connected to a tank for irrigation liquid, and an outlet to a distribution pipe for watering plants and a software device with automatic control the process of watering plants according to specified programs. An additional control unit is introduced into the irrigation system, the output of which is connected to the irrigation fluid supply device, and the corresponding inputs are connected to the software device, to the manual irrigation switch and to the irrigation delay switch, the outputs of which are connected to the input of the software device and to the input of the irrigation parameter adjustment unit, the other input of which is connected to the corresponding output of the manual watering switch, and the input-output is connected to the input-output of the software device.

The disadvantage of the design of this system of watering plants is the presence of a distribution pipeline, that is, the lack of selectivity. Therefore, all plants receive the same amount of water, regardless of individual needs. As a result, the soil under some plants is too dry, and under others - too moist. This can lead to a slowdown in the growth and development of plants and even to their death. Therefore, you have to inspect each plant and manually water those that lack moisture, and those plants that are in waterlogged conditions, temporarily disconnect from the general irrigation system until the soil beneath them dries.

The problem solved by the utility model is to develop the design of a device for automatic watering of plants, providing individual watering of two or more plants.

To solve this problem, a device for automatic watering of plants is used, containing a container with a medium for growing at least two plants, in which there are receiving nozzles with holes for supplying irrigation fluid to plants, a container for irrigation fluid with an irrigation fluid supply device having an outlet pipe with a tip and a software device with the ability to automatically control the process of watering plants according to specified programs. An additional drive controlled from a software device is introduced into the device for automatic watering of plants to move the tip from one receiving branch pipe to another by a distance equal to the distance between the receiving branch pipes. The distance between the receiving nozzles can be fixed.

This design of the installation allows for individual watering of each plant. Therefore, you can not manually water those that lack moisture, and those plants that are in waterlogged conditions, temporarily disconnect from the general irrigation system until the soil beneath them dries. It is enough to adjust the irrigation program by setting the optimal amount of irrigation fluid supplied to a particular plant. To eliminate the possibility of a mismatch between the actual distance between the receiving pipes and the distance programmed in the software device, the receiving pipes are fixed, making it impossible to change their position. Figure 1 shows a diagram of a device for automatic watering of plants. A device for automatic watering of plants contains a container 1 with a medium for growing plants 2. In the container 1, at least two receiving pipes 3 with holes 4 are fixed for supplying the irrigation liquid to the plants 2. The irrigation liquid container 5 is equipped with an irrigation liquid supply device 6 having an output tube 7 with a tip 8. The software device 9 has the ability according to specified programs to co-ordinate the operation of the irrigation fluid supply device 6 and the drive 10 to move the tip 8 t 3 one suction nozzle to another receiver by a distance L. The value of the distance L is entered into the program.

A device for automatic watering of plants works as follows. At the beginning of irrigation, the axis of the tip 8 coincides with the axis of the first receiving pipe 3. From the software device 9, a signal is sent to turn on the device 6 for supplying irrigation fluid. The amount of irrigation fluid is set by the program. Irrigation fluid through the tube 7 with the tip 8 enters the first receiving pipe 3 and from it to the roots of the plants 2. Having reached the specified volume of the supplied irrigation fluid, the software device 9 turns off the device 6 for supplying irrigation fluid and turns on the actuator 10, which moves the tube 7 with the tip 8 at a distance L to align the axis of the tip 8 and the axis of the second receiving pipe. The watering cycle is repeated. Then the tube 7 with the tip 8 moves either to the next receiving pipe, if any, or returns to its original state.

Experimental tests of a device for automatic watering of plants showed that it allows you to individually water two or more plants with different flow rates of irrigation fluid.
