For hydroponic technology, nutrient solution is one of the important factors for the good growth of crops.

[0003] When hydroponics is carried out, nutrient solution is usually transported to each cultivation trough of the cultivation rack through a liquid supply device to provide the crops with the nutrients necessary for growth. For example, Chinese patent No. CN217523511U discloses an artificial light hydroponic plant cultivation system, in which nutrient solution is provided to the cultivation bed 102 on the cultivation rack 101 through a liquid supply device 108. Most of the prior art uses similar technology, but after the nutrient solution has been used for a period of time, more bacteria will breed, affecting the normal growth of crops. Some of them directly discharge the contaminated directly for convenience, and some add bactericidal pesticides to the nutrient solution for sterilization, which not only wastes more nutrient solution and water, but also causes the phenomenon of excessive pesticides in crops.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, the soilless cultivation technology of hydroponic cultivation is developing at an increasingly faster speed. The purity of the nutrient solution is one of the key factors affecting crop growth. The current hydroponic cultivation is to supply the nutrient solution made by the water-fertilizer integrated machine 4 to the cultivation trough 2 of the cultivation rack 1. However, the nutrient solution will breed bacteria after being used in the cultivation trough 2 for a period of time, affecting the growth of crops. The existing treatment method is to replace the nutrient solution with a new one or add pesticides for sterilization. On the one hand, both will cause waste, and on the other hand, they will cause secondary pollution, causing crops to carry more pesticides. Therefore, the inventor has made improvements in the existing hydroponic cultivation system and designed a hydroponic system with a sterilization device, which will be explained in detail below in conjunction with the diagram.

[0030] This embodiment provides a hydroponic cultivation system with a sterilization device, see Figure 1 and Figure 2, including a cultivation frame 1, the cultivation frame 1 can be set to a certain height as needed, and multiple layers of cultivation troughs 2 are arranged along the vertical height of the cultivation frame 1, and each layer is provided with multiple cultivation troughs 2. The two cultivation troughs 2 between the upper and lower layers are connected by a liquid pipe 3, so that the nutrient solution can flow into the cultivation trough 2 of each layer.

[0031] In this embodiment, a water-fertilizer integrated machine 4 is provided on one side of the cultivation frame 1. Figure 4 The water-fertilizer integrated machine 4 adopts existing equipment, which is a purchased part, and has a built-in circulation pump, which can transport the internal nutrient solution to the outside, and can transport the external nutrient solution back to the water-fertilizer integrated machine 4, wherein the liquid outlet pipe 5 and the liquid inlet pipe 6 are respectively connected with the cultivation troughs 2 at different heights. Specifically, in order to facilitate the entry and recovery of the nutrient solution, the liquid outlet pipe 5 is connected with the highest cultivation trough 2, and the liquid inlet pipe 6 is connected with the lowest cultivation trough 2. In order to enable the nutrient solution to flow completely through each cultivation trough 2, the liquid pipes 3 connecting the cultivation troughs 2 on two adjacent layers are staggered in the vertical direction, so that the nutrient solution flows in a "snake" shape in the cultivation troughs 2 on the upper and lower layers.

[0032] On the basis of the above structure, in order to be able to control the nutrient solution entering and flowing out of the cultivation trough 2, valves 12 are provided on the pipelines between the liquid outlet pipe 5 and the liquid inlet pipe 6 and the cultivation trough 2 and the liquid through pipe 3, and one or more valves 12 can be controlled individually to allow the nutrient solution of one or more cultivation troughs 2 to flow, and a valve 12 is provided at a position of the liquid outlet pipe 5 near the water-fertilizer integrated machine 4 to control the release of nutrient solution by the water-fertilizer integrated machine 4.

[0033] In the present embodiment, the hydroponic cultivation system also includes a water tank 8, and is connected to the water inlet of the water-fertilizer integrated machine 4 through a water outlet pipe 9. In order to press the water in the water tank 8 into the water-fertilizer integrated machine 4 and mix it with the internal liquid fertilizer to prepare a nutrient solution, the water outlet pipe 9 between the water-fertilizer integrated machine 4 and the water tank 8 is connected to a water pump 13. Secondly, as one of the main technical points of the utility model, a sterilization device 10 is provided on the water tank 8, which can sterilize the water in the water tank 8. In the present embodiment, in order to achieve a sterilization effect and not cause secondary pollution, the sterilization device 10 is an ozone sterilizer, and the specific model used is yj-005, and the air outlet is connected to the inside of the water tank 8 through the air outlet pipe 11. The ozone generated by the ozone sterilizer is transported to the water tank 8 through the air outlet pipe 11 to sterilize and disinfect the water, thereby improving the purity of water as one of the raw materials of the nutrient solution.

[0034] In this embodiment, as one of the other main technical points of the utility model, the liquid outlet pipe 5 and the liquid inlet pipe 6 are respectively connected to the nutrient solution sterilizer 7, combined with Figure 3In order to improve the disinfection effect of the nutrient solution, multiple groups of nutrient solution sterilizers 7 are arranged along the arrangement direction of the liquid inlet pipe 6 and the liquid outlet pipe 5. In the present embodiment, 2-4 groups of nutrient solution sterilizers 7 are arranged at intervals on the liquid outlet pipe 5 or the liquid inlet pipe 6, which are mainly customized according to the length of the liquid outlet pipe 5 or the liquid inlet pipe 6, and the distance between two adjacent groups of nutrient solution sterilizers 7 on the same pipeline is 2m-5m, which can sterilize and disinfect the nutrient solution in the pipeline to the greatest extent. In the present embodiment, the nutrient solution sterilizer 7 adopts an ultraviolet sterilizer, and the specific model adopted is AFUV-240W.

[0035] Specifically, before configuring the nutrient solution, first turn on the ozone sterilizer to sterilize the water in the water storage tank 8. After working for a certain period of time, start the water pump 13 to transport the water to the water-fertilizer integrated machine 4 and mix it with the liquid fertilizer. Start the circulation pump in the water-fertilizer integrated machine 4 to transport the configured nutrient solution outward through the liquid outlet pipe 5, and start the ultraviolet sterilizer on the liquid outlet pipe 5. The nutrient solution flowing is sterilized and disinfected through continuous irradiation of multiple sterilizers and added to each cultivation trough 2; after the nutrient solution has been used for a certain period of time, open the valve 12 between the bottom cultivation trough 2 and the liquid inlet pipe 6 and the liquid pipe 3, start the circulation pump and the ultraviolet sterilizer of the liquid inlet pipe 6, and transport the nutrient solution of the cultivation trough 2 along the liquid inlet pipe 6 to the water-fertilizer integrated machine 4. During the flow of the nutrient solution, the multiple ultraviolet sterilizers of the liquid inlet pipe 6 sterilize and disinfect the nutrient solution to complete the purification of the used nutrient solution. Then, the nutrient solution is transported back to the cultivation trough 2 through the liquid outlet pipe 5 and sterilized again, so that the nutrient solution is recycled.
