[0002] Hydroponics is a cultivation technique that uses nutrient solution for cultivation. Compared with soil cultivation, it is highly favored because it can accelerate the growth process of crops, has good product quality, is pollution-free, maintains a clean and hygienic production environment, and has few pests and diseases. However, when existing crops are grown hydroponically, their planting height is fixed and the amount of water used for each irrigation is the same, resulting in serious waste of water resources. In addition, when using pipeline modular planting, when certain crops with relatively vigorous root systems are planted, the pipelines may be blocked, causing water and nutrient solution to overflow and cause waste.

[0003] Therefore, it is necessary to provide an integrated intelligent multi-stage water-saving hydroponic device to solve the problems mentioned in the above background technology. Summary of the Invention

[0023] See also Figure 1-5 The present invention provides an integrated intelligent multi-stage water-saving hydroponic device, comprising:

[0024] A planting rack 1 is provided with a water tank 2 at the bottom, and multiple layers of hydroponic components 4 are arranged longitudinally at intervals above the planting rack 1. A water volume regulating module 21 and a fertilizer liquid concentration regulating module 3 are provided on the upper end and side of the water tank 2, respectively. The water volume regulating module 21 is connected with each of the hydroponic components 4 and the water tank 2 through a water pipe 5. The fertilizer liquid concentration regulating module 3 can add fertilizer liquid to the water flow supplied to the hydroponic component 4, and a lighting module 6 is provided above each of the hydroponic components 4, and a plant height and leaf surface data monitoring module 61 is also provided next to the lighting module 6.

[0025] It should be explained that the plant seedlings are placed in the hydroponic component 4, and water is pumped into the hydroponic component 4 through the water volume regulating module 21, and intermittent irrigation is carried out layer by layer from top to bottom, so that multiple irrigations can be carried out with one water, thereby reducing the waste of water resources. At the same time, fertilizer liquid is injected into the water body through the fertilizer liquid concentration regulating module 3 to ensure the growth needs of the plants. In addition, the height, leaf size and other data of the plants are monitored through the plant height and leaf surface data monitoring module 61, and then the growth status / stage is judged, and the feedback is fed back to the fertilizer liquid concentration regulating module 3 to automatically adjust the fertilizer liquid concentration and irrigation water volume in real time to ensure the normal growth of the plants and realize intelligent planting. Among them, the lighting module 6 can be supplied with energy by solar energy or a built-in power supply.

[0026] In this embodiment, the hydroponic component 4 includes:

[0027] The tube body 41 is a rectangular parallelepiped structure. A U-shaped cover plate 42 is detachably provided on the upper end of the tube body 41. A plurality of circular holes 43 are uniformly formed through the bottom end of the U-shaped cover plate 42 along its extension direction.

[0028] A limiting cylinder 44 is longitudinally slidably disposed in the circular hole 43. A flexible support body 45 is provided in the circular hole 43 for limiting position. The flexible support body 45 is a splicable columnar structure with a limiting hole provided at the central splicing seam. A fixing plate extends horizontally along the lower end of the limiting cylinder 44; and

[0029] The suspension capsules 46 are fixed on both sides of the fixing plate along the extension direction of the tube body 41 .

[0030] It should be explained that the provision of the detachable U-shaped cover 42 facilitates the harvesting of plants and the inspection of the root system. When the seedlings are placed, they are elastically supported by the flexible support body 45 to avoid large deviations in the growth posture of the plants.

[0031] In this embodiment, a water inlet and a water outlet are respectively provided at both ends of each tube body 41, the water inlet is positioned higher than the water outlet, and solenoid valves are provided at both the water inlet and the water outlet, and the water inlets and water outlets of the longitudinally adjacent tube bodies 41 are arranged alternately.

[0032] That is to say, after the water is pumped into the topmost tube body 41, it flows downward in an S shape between the tube bodies 41 for irrigation, and by controlling the solenoid valve, the water can be temporarily stored or moved downward in each layer of the hydroponic component 4, gradually and fully irrigating each layer of plants. In the case of limited water, irrigation can be carried out layer by layer to avoid waste of water resources, and at the same time prevent the roots of the plants from being immersed in water for a long time, causing root rot and affecting plant growth.

[0033] In this embodiment, an irrigation water level monitoring module 461 and a fertilizer concentration detection module 462 are installed on the side of each suspension capsule 46 within each hydroponic assembly 4. These modules are used to monitor the water level and fertilizer concentration of each layer during irrigation. This monitoring allows for analysis of the degree of attenuation of fertilizer concentration and water level, allowing for appropriate adjustments to fertilizer concentration and irrigation volume to avoid significant differences in fertilizer concentration or water level between upper and lower layers, which could lead to insufficient nutrients for growth or inadequate irrigation.

[0034] In this embodiment, a reel 47 is provided above the fixing plate and beside the circular hole 43 . The reel 47 is connected to the fixing plate via a rope 48 . A coil spring is provided inside the reel 47 to reel the rope 48 .

[0035] It should be explained that when the plant switches between irrigation and non-irrigation states, the suspension bag 46 can rise and fall freely with the change of water flow, ensuring that the root system is in full contact with the water body to adapt to various stages of plant growth and avoid waste of water resources caused by excessive irrigation. It should be noted that when in the non-irrigation state, the suspension bag 46 is in a suspended state under the action of the rope body 48.

[0036] In this embodiment, the reel 47 is provided with a plant weight sensing module 471 and a temperature and humidity monitoring module 472, respectively, for monitoring the plant growth status and ambient temperature and humidity. The data is fed back to the lighting module 6 to adaptively adjust the lighting intensity and duration, ensuring that the plant is always in a suitable growth environment.

[0037] In this embodiment, a plurality of strip sponges 49 are provided at intervals perpendicular to the extension direction of the bottom of the tube body 41. The provision of the strip sponges 49 reduces the evaporation of residual water at the bottom of the tube body 41 after irrigation, and at the same time, can temporarily store some water, thereby preventing poor plant growth caused by long irrigation intervals.

[0038] In this embodiment, the buoyancy of the suspension capsule 46 during plant irrigation is greater than the friction between the limiting cylinder 44 and the circular hole 43. This ensures that the suspension capsule 46 can pull the plant roots upward during each irrigation, allowing them to fully contact the water body. This also prevents the roots from being immobilized for a long time, causing them to block the irrigation water flow and affect the irrigation effect.

[0039] During the specific implementation, the plant seedlings are placed in the hydroponic component, water is pumped into the hydroponic component through the water volume regulating module, and intermittent irrigation is carried out layer by layer from top to bottom. At the same time, fertilizer liquid is injected into the water body through the fertilizer liquid concentration regulating module. The growth status and environment of the plant are judged through the plant height and leaf surface data monitoring module, the plant weight sensing module, and the temperature and humidity monitoring module, and the feedback is fed back to the fertilizer liquid concentration regulating module to automatically adjust the fertilizer liquid concentration, irrigation water volume, and lighting time and frequency in real time to ensure the normal growth of the plant and realize intelligent hydroponic planting.

[0040] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
