Implementation of the utility model

The device for watering plants consists of a mixing tank 1 with a liquid level sensor 12 located inside, connected by pipes 2 to the water supply inlet with a water temperature sensor 13 through a filter 16 and a water pump 3 with an electronic control unit 4, also connected by pipes 2 from the inlet supply of the solution to the mixing tank 1 through the water pump 3 with the electronic control unit 4, the solenoid valve 7 and the flow meter 6 with the containers for the solution 5. On the nozzles 2 on the side of the outlet of the solution from the mixing tank 1 there is a water pump 3 with an electronic control unit 4, a filter 16 , conductivity sensor 8 and solution pH sensor 9, flow meters 6 and electromagnetic valves 7. The control unit 10 is connected with the possibility of feedback by interface wires 15 with the liquid level sensor 12 located inside the mixing tank 1, the information display device 10, the solar radiation sensor 14, the sensor conductivity 8 and solution pH sensor 9, with 4 electronic control units, 6 flow meters and 7 solenoid valves.

The claimed utility model is used as follows.

On the one hand, water is supplied to the mixing tank 1 through a branch pipe 2 with a water temperature sensor 13 using a water pump 3 through a filter 16. On the other hand, a chemical solution is supplied to the mixing tank 1 using a water pump 3 through a filter 16, an electrovalve 7 and a flow meter 6 from the solution tank 5. The liquid obtained as a result of mixing through the pipe 2 through the filter 16 and the water pump 3 is supplied to the outlet solenoid valve 7 with the flow meter sensor 6. The control unit 10 continuously processes the incoming information from the liquid level sensor 12 located in the mixing tank 1, the solar radiation sensor 14, with an electronic pump control unit 5 and an electrical conductivity sensor 8 and a solution pH sensor 9. Depending on the indicators of the sensors, the operation of the outlet solenoid valves 7 and water pumps 3 is adjusted.

An example of achieving a technical result

When using a plant watering device, the operating mode of the control unit 10 is initially set, which takes into account the amount and volume of the output solution from the mixing tank 1 through the flow meters 6, its composition and physical properties (electrical conductivity and pH) depending on the parameters of the external environment. The use of information by the control unit 10 from the solar radiation sensor 14 makes it possible to control the level of solar radiation in the external environment and controls the operation of the water pump 3 for supplying the solution from the mixing tank 1 to the outlet solenoid valve 7. Placement of the water pump 3 on the branch pipe 2 at the place where water is supplied to the mixing tank 1 and at the point of water intake from the mixing tank 1 allows using the control unit 10 to control and change the physical properties of the irrigation solution.

The increase in the number of use of solution tanks 5 makes it possible, by means of the control unit 10, to mix in the mixing tank 1 and distribute through the outlet solenoid valve 7 different compositions of the solution.

An increase in the number of outlet solenoid valves 7 in pipes 2 from the outlet of the solution from the mixing tank 1 using the control unit 10 allows organizing the supply of the solution to several places both simultaneously and at specified intervals.

The placement of the water temperature sensor 13 in the branch pipe 2 of the water supply to the mixing tank 1 allows you to control the temperature of the solution in the mixing tank 1. The placement of the liquid level sensor 12 in the mixing tank 1 prevents the operation of the water pump 3 in the absence of a given volume of solution in the mixing tank 1.

Rationale for the achievement of the technical result

A solar radiation sensor is connected to the control unit, which allows measuring solar activity in the wavelength range from 400 nm to 700 nm, used by plants for photosynthesis (chlorophyll absorbs photons from 400 nm to 700 nm with 100% efficiency). Measuring this parameter for certain time intervals makes it possible to control photosynthesis for various plant species by changing the time intervals for supplying the solution and pauses in supplying the outlet solenoid valve by the control unit. Simultaneous processing of information by the control unit about the composition of the irrigation solution, solar activity and the volume of the irrigation solution supplied makes it possible to control the process of water movement through the plants and its evaporation through the external organs of the plant.
