Technical Field

[0001] This utility model relates to the field of soilless potato cultivation technology, and in particular to an automatic light control device for soilless potato cultivation. Background Technology

[0002] With the development of agricultural technology, soilless potato cultivation has gradually become the mainstream planting method. It eliminates soil limitations and provides nutrients for potato growth through nutrient solutions, offering advantages such as high yield and fewer pests and diseases. Light is a key factor affecting photosynthesis and tuber development in soilless potato cultivation; its intensity, duration, and distribution directly determine the growth quality and final yield of the potatoes. However, existing soilless potato cultivation devices have several shortcomings:

[0003] 1) Lack of automatic shading device: When the light is too strong, it is not possible to automatically shade according to the actual light intensity, which can easily lead to problems such as leaf burn and growth inhibition of potato plants due to strong light. In addition, manual adjustment of the shading net is not only inefficient, but also difficult to guarantee timeliness and accuracy.

[0004] 2) Lack of supplemental lighting: When natural light is insufficient, it cannot provide enough light for potato growth, resulting in insufficient photosynthesis of the plant, affecting the normal growth and development of potatoes, and reducing potato yield and quality.

[0005] Therefore, there is an urgent need to develop an automatic light control device for soilless potato cultivation in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an automatic light control device for soilless potato cultivation, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic light control device for soilless potato cultivation, comprising a base and a support, wherein the support is located on the top of the base; a light control mechanism and a cultivation box assembly are installed on the upper end of the support, an infusion assembly is provided at the lower part of the cultivation box assembly, and a controller located on one side of the support is installed on the top of the base;

[0008] The lighting control mechanism includes a support column, the upper end of which is fitted with a hollow top plate, and a sunshade component is installed inside the hollow top plate.

[0009] Preferably, there are four support columns, one of which is equipped with a brightness detector on the side near the cultivation box assembly. The brightness detector is electrically connected to the controller. Multiple evenly distributed supplementary lights and supplementary light strips are fixedly installed at the bottom of the hollow top plate. A first groove is formed in the inner peripheral wall of the hollow top plate. Second grooves are formed on the left and right sides of the hollow top plate, located inside the first groove. The supplementary lights and supplementary light strips are all electrically connected to the controller.

[0010] Preferably, the sunshade assembly includes a servo motor, which is fixedly installed on one side of the hollow top plate and electrically connected to a controller; the output end of the servo motor passes through the hollow top plate and is connected to a roller located inside the first groove, a sunshade cloth is fixedly connected to the roller, a positioning rod is fixedly connected to the end of the sunshade cloth away from the roller, and sliders adapted to the second groove are fixedly connected to both ends of the positioning rod; the sunshade assembly also includes two hydraulic rods fixedly installed inside the first groove, the movable ends of the two hydraulic rods are respectively fixedly connected to both ends of the positioning rod, and the hydraulic rods are electrically connected to the controller.

[0011] Preferably, the cultivation box assembly includes four cultivation box bodies fixedly installed on the top of the support. A filter frame is detachably installed inside each cultivation box body. The infusion assembly includes drainage pipes and a water pump. There are three drainage pipes, each connected at both ends to the upper and lower cultivation box bodies respectively. A first solenoid valve is installed on each drainage pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. Achieving Intelligent Automatic Light Adjustment: This invention monitors light intensity in real time using a brightness detector and transmits the data to a controller. The controller automatically controls the operation of the shading components and supplemental lighting equipment based on preset thresholds. When the light is too strong, a servo motor and hydraulic rod work together to unfold the shading cloth to block sunlight; when the light is insufficient, supplemental lights and light strips are automatically activated. This avoids the inefficiency and untimely nature of manual adjustment, precisely ensuring that potato plants grow in a suitable light environment and preventing the effects of strong light burn and insufficient light on growth and development.

[0015] 2. Optimized Nutrient Solution Circulation Management: This invention is equipped with a nutrient solution delivery system. Under the control of the controller, the water pump, solenoid valve, and drainage pipe work together to achieve automatic circulation and replenishment of the nutrient solution.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1 to 6 As shown, an automatic light control device for soilless potato cultivation includes a base 1 and a support 2, with the support 2 located on top of the base 1. A light control mechanism 3 and a cultivation box assembly 4 are installed on the upper end of the support 2, and an infusion assembly 5 is installed at the lower part of the cultivation box assembly 4. A controller 6 located on one side of the support 2 is installed on the top of the base 1. The light control mechanism 3 includes a support column 31, with a hollow top plate 32 installed on the upper end of the support column 31. A shading assembly 33 is installed inside the hollow top plate 32.

[0026] It should be specifically noted that there are four support columns 31, one of which is equipped with a brightness detector 311 on the side near the cultivation box assembly 4. The brightness detector 311 is electrically connected to the controller 6. Multiple evenly distributed supplementary lights 321 and supplementary light strips 322 are fixedly installed at the bottom of the hollow top plate 32 for supplementing light to the potatoes at night or when there is insufficient light. A first groove 323 is opened in the inner peripheral wall of the hollow top plate 32, and a second groove 324 is opened on the left and right sides of the hollow top plate 32, located inside the first groove 323. The supplementary lights 321 and supplementary light strips 322 are all electrically connected to the controller 6.

[0027] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6 The sunshade assembly 33 includes a servo motor 331, which is fixedly installed on one side of the hollow top plate 32 and electrically connected to the controller 6. The output end of the servo motor 331 passes through the hollow top plate 32 and is connected to a roller 332 located inside the first groove 323. A sunshade cloth 333 is fixedly connected to the roller 332. A positioning rod 334 is fixedly connected to one end of the sunshade cloth 333 away from the roller 332. Slider blocks 335 that are adapted to the second groove 324 are fixedly connected to both ends of the positioning rod 334.

[0028] It should be noted that the sunshade assembly 33 also includes two hydraulic rods 336 fixedly installed inside the first groove 323. The movable ends of the two hydraulic rods 336 are fixedly connected to the two ends of the positioning rod 334, and the hydraulic rods 336 are electrically connected to the controller 6. The length and width of the sunshade cloth 333 are both 1-5 mm greater than the length and width of the inner wall of the hollow top plate 32.

[0029] Furthermore, when the light is too strong, the controller 6 sends instructions to the servo motor 331 and the hydraulic rod 336. The servo motor 331 rotates clockwise, driving the roller 332 to rotate. At the same time, the movable end of the hydraulic rod 336 retracts inward, pulling the positioning rod 334 and the sliders 335 at both ends to slide in the second groove 324, so that the shade cloth 333 unfolds from the roller 332, covering the central area of ​​the hollow top plate 32, blocking the excessive sunlight and preventing the potato plants from being damaged by strong light.

[0030] Furthermore, when the light is suitable, the controller 6 controls the servo motor 331 to rotate counterclockwise, the movable end of the hydraulic rod 336 is pushed outward, pushing the positioning rod 334 to drive the slider 335 to slide in the opposite direction, and the roller 332 simultaneously rolls the shade cloth 333 back onto the roller 332, ensuring that the natural light fully illuminates the plant.

[0031] Furthermore, when there is insufficient light, the controller 6 triggers the supplemental lighting 321 and the supplemental lighting strip 322 to turn on. These supplemental lighting devices are distributed at the bottom of the hollow top plate 32, providing additional light to the potato plants at night or during periods of insufficient light, maintaining normal photosynthesis and ensuring the plant's growth needs.

[0032] Please see Figures 1 to 3 As shown, the cultivation box assembly 4 includes four cultivation box bodies 41 fixedly installed on the top of the support 2. A filter frame 42 is detachably installed inside the cultivation box body 41. The infusion assembly 5 includes a drainage pipe 51 and a water pump 52. There are three drainage pipes 51. The two ends of each drainage pipe 51 are connected to the upper cultivation box body 41 and the lower cultivation box body 41, respectively. A first solenoid valve 54 is installed on the drainage pipe 51. The water pump 52 is fixedly installed on the top of the base 1. The inlet and outlet of the water pump 52 are connected to a second inlet pipe 55 and an outlet pipe 56, respectively. The other end of the second inlet pipe 55 is connected to the bottom cultivation box body 41, and the other end of the outlet pipe 56 is connected to the top cultivation box body 41. A first inlet pipe 53 is connected to the side of the top cultivation box body 41. A second solenoid valve 57 is installed on the first inlet pipe 53. The first solenoid valve 54, the second solenoid valve 57, and the water pump 52 are all electrically connected to the controller 6.

[0033] It should be specifically noted that the ends of the drainage pipe 51, the second inlet pipe 55, and the outlet pipe 56 that penetrate and extend into the main body of the cultivation box 41 are all located inside the filter frame 42; this prevents debris or plants in the upper cultivation box main body 41 from entering the lower cultivation box main body 41 and prevents the pipes from becoming blocked.

[0034] Please see Figures 1 to 6 As shown, the working principle of the entire device in actual use is as follows: Step 1, Light Monitoring and Adjustment: After the device is started, the brightness detector 311 installed on the support column 31 monitors the ambient light intensity in real time and transmits the data to the controller 6. The controller 6 analyzes and judges the data according to the preset light intensity threshold, and then controls the light control mechanism 3 to perform corresponding operations:

[0035] When the sunlight is too strong: the controller 6 sends a command to the servo motor 331 and the hydraulic rod 336. The servo motor 331 rotates clockwise, driving the roller 332 to rotate. At the same time, the movable end of the hydraulic rod 336 retracts inward, pulling the positioning rod 334 and the sliders 335 at both ends to slide in the second groove 324, so that the shade cloth 333 unfolds from the roller 332, covering the central area of ​​the hollow top plate 32, blocking the strong sunlight and preventing the potato plants from being damaged by strong light.

[0036] When the light is suitable: the controller 6 controls the servo motor 331 to rotate counterclockwise, the movable end of the hydraulic rod 336 is pushed outward, pushing the positioning rod 334 to drive the slider 335 to slide in the opposite direction, and the roller 332 simultaneously rolls the shade cloth 333 back onto the roller 332 to ensure that the natural light fully illuminates the plant.

[0037] When there is insufficient light: Controller 6 triggers the supplemental light 321 and supplemental light strip 322 to turn on. These supplemental lighting devices are distributed at the bottom of the hollow top plate 32. At night or during periods of insufficient light, they provide additional light to potato plants, maintain normal photosynthesis, and ensure the plant's growth needs.

[0038] Step 2, Nutrient Solution Circulation and Supply: Simultaneously with light regulation, the infusion unit 5, under the control of the controller 6, completes the circulation and replenishment of the nutrient solution.

[0039] Nutrient solution replenishment: When fresh nutrient solution needs to be replenished, the controller 6 opens the second solenoid valve 57, and the nutrient solution flows into the main body of the cultivation box 41 at the top through the first inlet pipe 53 to provide nutrients for the potato plants.

[0040] Nutrient solution circulation: Controller 6 starts water pump 52 and simultaneously opens the first solenoid valve 54. Water pump 52 draws nutrient solution from the bottom cultivation box body 41 through the second inlet pipe 55, and delivers it to the top cultivation box body 41 through the outlet pipe 56. Then, the nutrient solution is sequentially delivered to each cultivation box body 41 through the drainage pipe 51, realizing the circulation of nutrient solution within the cultivation box assembly 4 and continuously supplying nutrients to the potato plants. During this process, the filter frame 42 inside the cultivation box body 41 plays a filtering role, preventing plant roots, impurities, etc. from entering the pipes, ensuring that the drainage pipe 51, the second inlet pipe 55, and the outlet pipe 56 are unobstructed, and maintaining the stable operation of the nutrient solution circulation system.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
