Description

Technical Field

[0001] The utility model relates to an intelligent soilless cultivation facility and belongs to the technical field of soilless cultivation. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat, forest leaf mold, vermiculite and other media as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time. It can be carried out in places with suitable light and temperature but no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply.

[0003] Soilless cultivation is divided into hydroponics, mist cultivation and substrate cultivation according to different cultivation media. Hydroponics refers to a cultivation method in which the plant roots are directly in contact with the nutrient solution without the use of a substrate. The earliest hydroponics was to immerse the plant roots in the nutrient solution for growth. This method will cause hypoxia and cause root death in severe cases. The nutrient film method is often used for hydroponics. Even a very thin layer of nutrient solution is continuously circulated through the crop root system, which not only ensures the continuous supply of water and nutrients to the crop, but also continuously supplies fresh oxygen to the root system. There are many ways to supply liquid for soilless cultivation, including nutrient film irrigation, flooding, double-walled pipe irrigation system, drip irrigation system, siphon method, spray method and manual irrigation. In summary, it can be divided into two major categories: circulating water and non-circulating water. At present, the most widely used methods in production are nutrient film method and drip irrigation.

[0004] Plants need sufficient light, suitable temperature, sufficient water and certain nutrients to grow healthily. In order to provide a suitable growth environment for soilless plants, it is necessary to control the pH value and EC value of the nutrient solution, as well as the temperature and light in the environment according to the characteristics of the plants. Traditional methods mostly use manual or simple sensor control units for adjustment, which cannot guarantee the healthy and rapid growth of plants to the greatest extent, and is not conducive to the development of industrialization.

[0005] Therefore, it is necessary to develop a new type of intelligent soilless cultivation equipment to solve the above problems. Summary of the invention

[0022] See also Figure 1 to Figure 2 As shown, an intelligent soilless cultivation facility shown in an embodiment of the utility model has a high degree of automation, is easy to control, and can ensure the healthy and rapid growth of plants to the greatest extent. It includes: a device body and an intelligent control system arranged on the device body.

[0023] The main body of the equipment includes a bracket 1, a water tank 2, a water pipe 1 3, a water pipe 2 4, an overflow pipe 1 5, an overflow pipe 2 6, an overflow pipe 3 7 and a seedling cup 8. The bracket 1 and the water tank 2 are both arranged on the ground, the water tank 2 is located on one side of the bracket 1, the water pipe 1 3 is arranged on the bracket 1, the water pipe 2 4 is arranged on the water pipe 1 3, the overflow pipe 1 5 is arranged on the water pipe 2 4 and is connected, the overflow pipe 1 5 is located in the water pipe 1 3, the overflow pipe 2 6 is arranged on the water pipe 2 4 and is located in the overflow pipe 1 5, the water inlet of the overflow pipe 2 6 is higher than the overflow pipe 1 5, and multiple groups of water pipes 2 4 are arranged at equal intervals, wherein two adjacent water pipes 2 4 The space existing between them is a closed space. There is a closed space between the topmost water pipe 2 4 and the water pipe 1 3 and between the lowest water pipe 2 4 and the water pipe 1 4. The outlet of the overflow pipe 2 6 extends to the top of the water pipe 2 4 below and is not higher than the overflow pipe 1 5. The overflow pipe 3 7 is arranged between the lowest water pipe 2 4 and the water storage tank 2. The overflow pipe 3 7 is located in the overflow pipe 1 5. The seedling cup 8 is installed on both ends of the water pipe 2 4. The bottom wall of the seedling cup 8 is provided with a through hole, and the through hole is located in the water pipe 2 4. A water pump 9 is provided in the water storage tank 2, and an inlet pipe 10 is provided between the water pump 9 and the top of the water pipe 3.

[0024] During specific use, the seedling cup containing seedlings or seeds is placed on water pipe 2 4, and the water pump 9 is started. The water pump 9 first transports the water or nutrient solution in the water tank 2 through the water inlet pipe 10 to the space formed between the topmost water pipe 2 4 and the water pipe 1 3, and enters the water pipe 2 4 through the overflow pipe 1 5. When the water or nutrient solution is higher than the overflow pipe 2 6, it enters the next closed space through the overflow pipe 2 6. By analogy, when the water or nutrient solution fills the closed space at the bottom, it will enter the water tank through the overflow pipe 3 7, thereby realizing irrigation of the seedlings or seeds or nutrient delivery.

[0025] The intelligent control system includes a temperature sensor probe 11, a water quality pH sensor probe 12, a nutrient solution EC concentration sensor probe 13, a light sensor probe 14, and a PLC controller 15 arranged in the main body of the device. The PLC controller 15 is electrically connected to the temperature sensor probe 11, the water quality pH sensor probe 12, the nutrient solution EC concentration sensor probe 13, and the light sensor probe 14 respectively. The intelligent control system also includes a constant temperature heating rod 16 arranged in the main body of the device, and a lighting group 17, a display screen 18 and a warning light 19 arranged on the main body of the device.

[0026] The intelligent control system can monitor the temperature, light intensity, pH value and EC value of the soilless cultivation equipment in real time and control the above environmental conditions within a range suitable for plant growth. The specific process is as follows:

[0027] The water quality pH sensor probe 12 monitors the pH value of the nutrient solution in the soilless cultivation equipment in real time, transmits the monitoring results to the PLC controller 15, and displays the pH value of the nutrient solution through the display screen 18. When the pH value is too high or too low, the warning light 19 lights up to remind the operator to add acid or alkali solution in time to adjust the nutrient solution to a pH value suitable for the growth of specific plants.

[0028] The nutrient solution EC concentration sensor probe 13 monitors the EC value of the nutrient solution in the soilless cultivation equipment in real time, transmits the monitoring result to the PLC controller 15, and displays the EC value of the nutrient solution through the display screen 18. When the EC value of the nutrient solution is too high, the PLC controller 15 will control the water pump 9 to start and inject water to dilute the nutrient solution; if the EC value is too low, the warning light 19 will light up to prompt the operator to add nutrient solution to adjust the concentration.

[0029] The temperature sensor probe 11 monitors the temperature in the soilless cultivation equipment in real time and transmits the monitoring results to the PLC controller 15. When the temperature in the equipment is lower than the lower limit of the suitable temperature of the current plant, the PLC controller 15 will control the constant temperature heating rod 16 to start heating; when the temperature in the equipment is higher than the upper limit of the suitable temperature of the current plant, the heating will stop.

[0030] The light sensor 14 monitors the light intensity near the soilless cultivation equipment in real time and transmits the monitoring results to the PLC controller 15. When the external light is too dark (such as cloudy, rainy or indoors where the sun is not visible), the PLC controller 15 will automatically turn on the lighting group 17 to achieve automatic supplementary light. The appropriate lighting time H for the corresponding plant is set on the PLC controller 15. When the sum of the natural lighting time and the lighting time of the lighting group 17 exceeds H, the lighting group 17 will automatically turn off.

[0031] In summary, the utility model can monitor the temperature, light intensity, pH and EC value of the soilless cultivation equipment in real time and display them on the display screen by adding an intelligent control system including a temperature sensor probe, a water pH sensor probe, a nutrient solution EC concentration sensor probe, a light sensor probe, and a PLC controller to the soilless cultivation equipment. Acid, alkali and high-concentration nutrient solution are added to the equipment accordingly according to the above information. Combined with a constant temperature heating rod, a water pump and a lighting group, only a small amount of manual operation is required to provide soilless cultivation equipment with suitable and constant conditions. The equipment can ensure the healthy and rapid growth of plants, is easy to control, and has a high degree of automation.
