DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following combination Figures 1 to 3 A plant hydroponic device and a plant factory provided in the embodiments of the present invention are described.

[0029] The present embodiment provides a plant hydroponic device, comprising: a hydroponic tank 1 , a water-permeable support 2 , a fertilizer supply machine 3 and a liquid level meter 4 .

[0030] Among them, the hydroponic tank 1 is filled with nutrient solution; the permeable support member 2 is arranged in the hydroponic tank 1, used to support the culture matrix, and used to immerse the bottom of the culture matrix in the nutrient solution, and plants such as strawberry seedlings 15 can be cultivated in the culture matrix; the fertilizer supply machine 3 is connected to the hydroponic tank 1 through a liquid inlet pipe, and is used to provide nutrient solution to the hydroponic tank 1; the liquid level meter 4 is arranged in the hydroponic tank 1, and is used to measure the depth of the nutrient solution in the hydroponic tank 1.

[0031] It can be seen from the above scheme that when in use, plants are cultivated in the culture matrix, and the culture matrix is placed on a permeable supporting member, and the bottom of the culture matrix is immersed in the nutrient solution in the hydroponic tank 1 through the permeable supporting member 2, forming a new cultivation method of "upper matrix cultivation, lower nutrient solution cultivation", thereby avoiding the plant roots from being completely immersed in the nutrient solution, which can not only meet the plant roots' absorption of nutrients, but also avoid the problem of poor root permeability; by setting a liquid level meter 4 to measure the depth of the nutrient solution in the hydroponic tank 1 in real time, and cooperating with the fertilizer supply machine 3, it can achieve fluid replenishment according to the consumption of the nutrient solution, and when the liquid level is less than the preset value, the nutrient solution can be replenished to the initial liquid level meter 4 numerical position through the fertilizer supply machine 3, so that the nutrient solution can always infiltrate the culture matrix so that the nutrients can be absorbed by the plant roots, effectively overcoming the problem of low irrigation accuracy in the plant matrix cultivation process and ensuring accurate supply of nutrient solution.

[0032] The above-mentioned permeable support member 2 can be a non-woven fabric. When in use, the non-woven fabric can be fixed to the inner side of the hydroponic tank 1 by snaps, etc., and a plant-specific culture medium or a cultivation pot with holes at the bottom can be placed on the non-woven fabric, and plants can be planted in the cultivation pot.

[0033] Furthermore, it also includes a waste liquid pool 5, which is connected to the hydroponic tank 1 through a liquid outlet pipe.

[0034] In this way, as the strawberry seedlings 15 grow, the nutrient solution is supplemented in the hydroponic tank 1 for a long time, which easily causes the accumulation of harmful components, not only affecting the normal growth of the strawberry seedlings 15, but also possibly polluting the cultivation environment. By arranging the waste liquid pool 5 and the liquid outlet pipe, the nutrient solution with harmful components accumulated in the hydroponic tank is transported to the waste liquid pool 5 for further processing to prevent direct discharge from causing environmental pollution.

[0035] The hydroponic tank 1 is provided with a liquid outlet and a liquid inlet, the liquid inlet is connected to the liquid inlet pipe, and the liquid outlet is connected to the liquid outlet pipe.

[0036] Furthermore, it also includes a disinfection device and a circulation pump 6. The disinfection device is connected between the waste liquid pool 5 and the fertilizer supply machine 3, and is used to send the nutrient solution in the waste liquid pool 5 to the fertilizer supply machine 3 after disinfection. The circulation pump 6 is arranged on the pipeline between the disinfection device and the waste liquid pool 5.

[0037] This embodiment further includes a controller, which is electrically connected to the fertilizer feeder 3, the liquid level gauge 4, and the circulation pump 6. The liquid level gauge 4 can be a liquid level sensor, which measures the depth of the nutrient solution in the hydroponic tank 1 in real time. In conjunction with the fertilizer feeder 3, the liquid level gauge 4 can automatically replenish the nutrient solution according to the consumption of the nutrient solution. A preset value can be set. When the measured liquid level is less than the preset value, the fertilizer feeder 3 replenishes the nutrient solution to the initial value of the liquid level gauge 4, ensuring that the nutrient solution can always penetrate the culture medium for absorption by the plant roots and automatically realizing the recycling of the nutrient solution.

[0038] In some embodiments, the fertilizer feeder 3 is further connected to a water supply pipe for connecting to a water supply device. This arrangement allows for the sterilized nutrient solution to be supplied with clean water to adjust the concentration of the nutrient solution, thereby better controlling the concentration of the nutrient solution to meet the growth needs of the plants.

[0039] In this embodiment, the disinfection device includes a first temporary storage tank 7 and a disinfection machine 8. The first temporary storage tank 7 is connected to the waste liquid pool 5 through a first pipeline, and the circulation pump 6 is arranged on the first pipeline; the disinfection machine 8 is connected between the first temporary storage tank 7 and the fertilizer supply machine 3 through a second pipeline.

[0040] In this way, by setting up the first temporary storage tank 7 to store a certain amount of nutrient solution therein, the disinfection machine 8 can conveniently disinfect the nutrient solution in the temporary storage tank, which not only plays a role in buffering and regulating the flow, but also can balance the demand for nutrient solution and fertilizer supply machine 3. When the fertilizer supply machine 3 needs to temporarily stop working or adjust the working speed, the first temporary storage tank 7 can store excess liquid to avoid liquid backflow, making the transportation process smoother, avoiding flow fluctuations from causing impact on downstream equipment, and protecting equipment such as the circulation pump 6 and the fertilizer supply machine 3.

[0041] Furthermore, the disinfection device also includes a second temporary storage tank 9, which is arranged between the disinfection machine 8 and the fertilizer supply machine 3, the second temporary storage tank 9 is connected to the disinfection machine 8 through a second pipeline, and the second temporary storage tank 9 is connected to the fertilizer supply machine 3 through a third pipeline.

[0042] In this way, by setting up a second temporary storage tank 9 to store the disinfected nutrient solution first, it helps to balance the flow difference between the disinfector 8 and the fertilizer supply machine 3, ensuring that the fertilizer supply machine 3 can stably receive an appropriate amount of liquid, playing a buffering and balancing role; and the disinfected nutrient solution can be further stabilized in the second temporary storage tank 9, which helps to reduce water quality fluctuations and reduce the impact on the fertilizer supply machine 3 due to sudden flow changes or water quality fluctuations, thereby extending the service life of the fertilizer supply machine 3. When the fertilizer supply machine 3 needs to temporarily stop working or adjust the working speed, the second temporary storage tank 9 can store excess liquid to avoid liquid backflow or waste.

[0043] In this embodiment, the hydroponic tank 1 includes a bottom plate 101, a pair of first side plates 102 and a pair of second side plates 103. The first side plates 102 are vertically connected to the bottom plate 101, and the second side plates 103 are obliquely connected to the bottom plate 101. Figure 2 As shown, the cross-section of the hydroponic tank 1 is trapezoidal, a pair of first side panels 102 are relatively connected to the two short sides of the bottom plate 101, a pair of second side panels 103 are relatively connected to the two long sides of the bottom plate 101, and both sides of the first side panel 102 are respectively connected to the pair of second side panels 103, together forming the hydroponic tank 1.

[0044] The plant hydroponic device provided by the present utility model can realize the circulating supply of nutrient solution. As the plant seedlings grow, the nutrient solution can be continuously added to the hydroponic tank to ensure that the culture medium is always immersed in the nutrient solution, so that the plant roots are in contact with the nutrient solution; the nutrient solution with accumulated harmful components is discharged into the waste liquid pool 5, and the nutrient solution in the waste liquid pool 5 is transported to the first temporary storage tank 7 through the circulation pump 6 through the pipeline, the disinfection machine 8 extracts the nutrient solution in the first temporary storage tank 7, and after disinfection, the nutrient solution is transported to the second temporary storage tank 9, the nutrient solution in the second temporary storage tank 9 is transported to the fertilizer supply machine 3 and mixed with clean water, and then transported to the hydroponic tank 1 through the fertilizer supply machine 3, thereby realizing the recycling of the nutrient solution.

[0045] Reference Figure 3 The embodiment of the present invention also provides a plant factory, including a cultivation room 10 and the above-mentioned plant hydroponic device. A plurality of hydroponic racks 11 are provided in the cultivation room 10, and the plant hydroponic device is arranged on the hydroponic racks 11. A fill light 13 is also provided in the cultivation room 10. The fill light 13 corresponds to the hydroponic tank 1 of the plant hydroponic device and is electrically connected to the controller. A plurality of strawberry seedlings 15 are cultivated in each hydroponic tank 1.

[0046] With such a configuration, due to the adoption of the above-mentioned plant hydroponic device, the plant factory has all the advantages of the above-mentioned plant hydroponic device, and by providing a light source in the cultivation room, the existing light is supplemented or strengthened, the growth environment of plants such as strawberry seedlings 15 is improved, and the growth of strawberry seedlings 15 is facilitated.

[0047] In this embodiment, a nutrient solution supply device is provided, which includes a liquid supply pipe 12 and may also include a liquid storage tank and a water pump. One end of the liquid supply pipe 12 is connected to the liquid storage tank, and the other end is connected to the hydroponic tank 1. The water pump is arranged on the liquid supply pipe 12 and is electrically connected to the controller for providing nutrient solution to the hydroponic tank 1 so that when the liquid level meter 4 detects that the liquid level has dropped to a preset height, the nutrient solution is replenished in time to ensure that the nutrient solution in the hydroponic tank 1 meets the growth needs of the strawberry seedlings 15.

[0048] Furthermore, it also includes a ventilation and temperature control device 14, which includes a circulation fan and an air conditioner. The circulation fan and the air conditioner are both electrically connected to the controller, and the circulation fan is set at the window of the cultivation room 10.

[0049] Thus arranged, by arranging circulating blower and air-conditioning in the cultivation chamber 10, the growth of plant such as strawberry seedling 15 is played a good regulating and controlling role, on the one hand, blower can promote the air circulation in the cultivation chamber 10, keep the air fresh, and reduce the influence of unfavorable meteorological conditions such as high temperature and high humidity on strawberry seedling 15, provide suitable growth environment for strawberry seedling 15, help to reduce the generation of disease, reduce the possibility of pathogenic microorganism breeding.On the other hand, by adjusting the set temperature of air-conditioning, it is possible to ensure that the temperature in the cultivation chamber 10 remains within the suitable range for the growth of strawberry seedling 15, and it is possible to ensure that it can obtain optimal growth conditions throughout the growth cycle. By rationally using these two types of equipment, a more stable, suitable growth environment can be created for the plant in the cultivation chamber 10, thereby improving the growth rate and the output of strawberry seedling 15.

[0050] The plant factory provided by the present invention transforms and combines the two methods of substrate cultivation and nutrient solution cultivation, combines the advantages of the substrate cultivation system and the hydroponic system, and forms a new cultivation system of "upper part - substrate cultivation, lower part - nutrient solution cultivation". The system is combined with the plant factory, and at the same time effectively overcomes the disadvantages of low irrigation accuracy and non-reusability of nutrient solution in the substrate cultivation system and poor root aeration, high labor intensity and high planting risk in the hydroponic system. Under the premise of ensuring the year-round production of strawberries, automatic irrigation can be started according to the evaporation of crops to ensure accurate supply of water and fertilizer to crops, and reduce the amount of labor. At the same time, the recycling of nutrient solution and precise temperature control are realized, which reduces the production cost of the plant factory to a certain extent, improves the utilization rate of water and fertilizer and the level of cultivation management, increases economic benefits, realizes the reuse and sustainable development of resources, and has a great driving effect on the future development of the strawberry industry.
