Description

Technical Field

[0001] This application relates to the field of planting equipment technology, and in particular to a photovoltaic planting box. Background Technology

[0002] With the development of urban agriculture and renewable energy technologies, photovoltaic planting boxes that combine photovoltaic power generation with plant cultivation are gradually emerging.

[0003] Existing photovoltaic (PV) planting boxes typically fix PV modules to the box body to provide power for supplemental lighting inside the box. However, because the solar altitude angle and azimuth angle constantly change throughout the day and throughout the year, fixed PV modules can only obtain optimal irradiance during limited periods, and their power generation efficiency is significantly reduced at other times due to the deviation in the incident angle.

[0004] To improve power generation efficiency, solar-tracking photovoltaic (PV) brackets are typically installed independently outside the container, making the system complex and bulky, thus negating the advantages of miniaturization and mobility of the planting box. Therefore, how to maximize the sun-facing surface of the PV modules while maintaining a compact and integrated design to improve power generation efficiency remains a pressing technical challenge for PV planting boxes. Utility Model Content

[0005] This application provides a photovoltaic planting box that can solve the problem of low power generation efficiency caused by the fixed angle of photovoltaic modules in related technologies.

[0006] This application provides a photovoltaic planting box; the photovoltaic planting box includes a support frame, an aeroponic tank, photovoltaic modules, a locking / unlocking mechanism, a planting board, and an infusion assembly. The aeroponic tank is installed on the bottom side of the support frame and is used to hold nutrient solution.

At least one of the two outermost photovoltaic units is movably connected to the support frame. Adjacent photovoltaic units are rotatably connected through at least one rotating part. The locking / unlocking mechanism is movably connected to the support frame and can switch between a locked state and an unlocked state. In the locked state, the locking / unlocking mechanism is configured to lock the photovoltaic units to the support frame so that the included angle between adjacent photovoltaic units is fixed. In the unlocked state, the locking / unlocking mechanism is configured to release the photovoltaic units to the support frame so that the included angle between adjacent photovoltaic units is adjustable. The planting board is disposed on the support frame and located between the aeroponic tank and the photovoltaic modules. The planting board is used to fix the plants. At least a portion of the infusion assembly is installed on the support frame. The inlet end of the infusion assembly is connected to the aeroponic tank, and the outlet end of the infusion assembly is used to supply nutrient solution to the plants on the planting board.

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] Please refer to Figures 1-4 As shown, this application proposes a photovoltaic planting box 1, which can improve the power generation efficiency of photovoltaic modules 30.

[0019] The photovoltaic planting box 1 includes a support frame 10, an aeroponic tank 20, photovoltaic modules 30, a locking / unlocking mechanism 40, a planting board 50, and an infusion assembly 60. The aeroponic tank 20 is installed on the bottom side of the support frame 10 and is used to hold nutrient solution. The photovoltaic modules 30 include multiple photovoltaic units 31 and multiple rotating parts 32. All photovoltaic units 31 are located on the top side of the support frame 10. At least one of the two outermost photovoltaic units 31 is movably connected to the support frame 10, and adjacent photovoltaic units 31 are rotatably connected via at least one rotating part 32. The locking / unlocking mechanism 40 is movably connected to the support frame 10 and can switch between a locked state and an unlocked state. In the locked state, the locking / unlocking mechanism 40 is configured to lock the photovoltaic units 31 to the support frame 10, fixing the angle between adjacent photovoltaic units 31. In the unlocked state, the locking / unlocking mechanism 40 is configured to release the photovoltaic units 31 from the support frame 10, allowing the angle between adjacent photovoltaic units 31 to be adjustable. The planting board 50 is mounted on the support 10 and located between the aeroponic tank 20 and the photovoltaic module 30. The planting board 50 is used to fix the plants. At least part of the infusion assembly 60 is mounted on the support 10. The inlet end of the infusion assembly 60 is connected to the aeroponic tank 20, and the outlet end of the infusion assembly 60 is used to supply nutrient solution to the plants on the planting board 50.

[0020] The following combination Figures 1-7 The specific structure of the photovoltaic planting box 1 will be described in detail.

[0021] like Figures 1-4 As shown, the photovoltaic planting box 1 includes a support frame 10, an aeroponic tank 20, a photovoltaic module 30, a locking and unlocking component 40, a planting board 50, and an infusion assembly 60.

[0022] The support frame 10 serves as the framework for the photovoltaic planting box 1, supporting components such as the aeroponic tank 20, photovoltaic modules 30, locking and unlocking components 40, planting board 50, and infusion assembly 60. The specific material of the support frame 10 is not limited here; designers can design it appropriately according to actual needs. For example, the material of the support frame 10 can be, but is not limited to, stainless steel or aluminum alloy. The specific structure of the support frame 10 will be described in detail below.

[0023] The aeroponic tank 20 is used to hold the nutrient solution and is installed on the bottom side of the support 10. The specific installation method between the aeroponic tank 20 and the support 10 is not limited here; designers can design it reasonably according to actual needs. For example, the aeroponic tank 20 can be detachably connected to the support 10 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the aeroponic tank 20 can also be non-detachably fixedly connected to the support 10 by riveting or welding, but not limited to this method.

[0024] The photovoltaic module 30 serves as the energy conversion device for the photovoltaic planting box 1. The photovoltaic module 30 includes multiple photovoltaic units 31 and multiple rotating parts 32.

[0025] Photovoltaic units 31 are used to convert solar energy into electrical energy. All photovoltaic units 31 are located on the top side of the support 10, and at least one of the two outermost photovoltaic units 31 is movably connected to the support 10; for example, both of the outermost photovoltaic units 31 may be movably connected to the support 10; or, for another example, one of the two outermost photovoltaic units 31 may be movably connected to the support 10 and the other may be fixedly connected to the support 10.

[0026] The rotating component 32 serves as a connector to link two adjacent photovoltaic units 31, allowing them to rotate relative to each other. This maximizes the sunlight-receiving surface of the photovoltaic unit 31, thereby improving its power generation efficiency. The specific form of the rotating component 32 will be described in detail below.

[0027] Two adjacent photovoltaic units 31 are rotatably connected by at least one rotating member 32. For example, when two adjacent photovoltaic units 31 are rotatably connected by one rotating member 32, the rotating member 32 is located in the middle of the two adjacent photovoltaic units 31; or, for example, when two adjacent photovoltaic units 31 are rotatably connected by multiple rotating members 32, the multiple rotating members 32 are equally spaced between the two adjacent photovoltaic units 31.

[0028] like Figures 1-4 As shown, the locking and unlocking component 40 serves as a locking structure of the photovoltaic planting box 1 to fix the relative position between the photovoltaic unit 31 and the support 10. On the other hand, the locking and unlocking component 40 serves as a releasing structure of the photovoltaic planting box 1 to change the relative position between the photovoltaic unit 31 and the support 10.

[0029] The locking / unlocking component 40 is movably connected to the bracket 10. The specific movable connection method between the locking / unlocking component 40 and the bracket 10 is not limited here. Designers can make reasonable designs according to actual needs. It is also understood that the specific movable connection method between the locking / unlocking component 40 and the bracket 10 will be different for different specific forms of the locking / unlocking component 40.

[0030] The lock / unlock device 40 has a locked state and an unlocked state, and the lock / unlock device 40 can switch between the locked state and the unlocked state.

[0031] When the locking / unlocking component 40 is in the locked state, it is configured to lock the photovoltaic unit 31 to the support 10, thereby fixing the relative position between the photovoltaic unit 31 and the support 10 and thus fixing the included angle between two adjacent photovoltaic units 31. When the locking / unlocking component 40 is in the unlocked state, it is configured to release the photovoltaic unit 31 from the support 10, thereby changing the relative position between the photovoltaic unit 31 and the support 10 and thus making the included angle between two adjacent photovoltaic units 31 adjustable. By switching between the locked and unlocked states, the locking / unlocking component 40 can adjust the angle between two adjacent photovoltaic units 31, allowing the sun-receiving surface of the photovoltaic unit 31 to face the sun as much as possible, thereby improving the power generation efficiency of the photovoltaic unit 31.

[0032] The planting board 50 is used to fix the plant. The planting board 50 has multiple fixing holes 51. The plant is fixed by inserting the roots of the plant into the fixing holes 51.

[0033] The planting board 50 is mounted on the support 10 and located between the aeroponic tank 20 and the photovoltaic module 30. The specific arrangement between the planting board 50 and the support 10 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the planting board 50 and the support 10 may not have any connection relationship, and the planting board 50 can be directly tilted and placed on the support 10. Alternatively, the planting board 50 and the support 10 may also have a connection relationship. In this case, the planting board 50 may be detachably connected to the support 10 by at least one of the following methods: screw connection, snap connection, or plug connection.

[0034] The infusion component 60 serves as the liquid supply pipeline for the photovoltaic planting box 1. The specific structure of the infusion component 60 will be described in detail below.

[0035] At least a portion of the infusion assembly 60 is mounted on the support 10; the specific installation method between the infusion assembly 60 and the support 10 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the infusion assembly 60 can be detachably connected to the support 10 by means of screwing, snap-fitting, plugging or binding; for another example, the infusion assembly 60 can also be non-detachably connected to the support 10 by means of riveting or welding.

[0036] The inlet end of the infusion assembly 60 is connected to the aeroponic tank 20, and the outlet end of the infusion assembly 60 is used to supply nutrient solution to the plants on the planting board 50. Thus, the nutrient solution in the aeroponic tank 20 flows into the infusion assembly 60 from the inlet end, passes through the infusion assembly 60, and then flows out from the outlet end of the infusion assembly 60 and is transported to the plant roots. The "inlet end" of the infusion assembly 60 is the part of the infusion assembly 60 used to allow the nutrient solution from the aeroponic tank 20 to flow into the infusion assembly 60; the "outlet end" of the infusion assembly 60 is the part of the infusion assembly 60 used to allow the nutrient solution to flow out of the infusion assembly 60.

[0037] Based on the photovoltaic planting box 1 in this embodiment, by designing photovoltaic modules 30, solar energy can be converted into electrical energy to provide green energy for electrical components such as the infusion module 60, enabling the hydroponic system inside the box to operate off-grid or with low mains power. By designing multiple photovoltaic units 31 and multiple rotating parts 32, adjacent photovoltaic units 31 are rotatably connected by at least one rotating part 32. Furthermore, a locking / unlocking part 40 is designed; by switching between locked and unlocked states, the angle between adjacent photovoltaic units 31 can be adjusted, thereby allowing the photovoltaic unit 31 to receive... The surface of the plant should face the sun as much as possible to improve power generation efficiency. By designing the infusion component 60, which delivers nutrient solution to the plant roots, hydroponics can be achieved, eliminating soil-borne diseases, reducing pesticide use, and saving energy and protecting the environment. By designing the photovoltaic module 30 above the planting board 50, "power generation on the upper layer and planting on the lower layer" can be achieved in the same vertical space, increasing the output per unit area and realizing agricultural-photovoltaic complementarity. In addition, the photovoltaic module 30 above can shade and cool the plants below during periods of strong sunlight, and it can also serve as a top barrier to reduce rainwater directly washing over the plants below.

[0038] It is worth mentioning that two adjacent photovoltaic units 31 are connected by at least one rotating part 32, and there is a gap between two adjacent photovoltaic units 31. This gap can play a role in stress relief, especially in the case of strong convective winds. The gap between two adjacent photovoltaic units 31 is used to allow fluid to pass through, which plays a role in stress relief and prevents damage to the photovoltaic module 30.

[0039] like Figures 1-4As shown, each photovoltaic unit 31 includes a photovoltaic panel 311 and a frame 312. The photovoltaic panel 311 is used to convert solar energy into electrical energy. The frame 312 is fixedly connected to the edge of the photovoltaic panel 311. The frame 312 of at least one of the two outermost photovoltaic units 31 is slidably connected to the bracket 10. The frames 312 of two adjacent photovoltaic units 31 are rotatably connected by at least one rotating member 32. The photovoltaic panel 311 can be detachably fixedly connected to the frame 312 by at least one of the following methods: screwing, snap-fitting, or plugging. The photovoltaic panel 311 can also be non-detachably fixedly connected to the frame 312 by riveting or gluing. By designing the photovoltaic panel 311 and the frame 312, the photovoltaic panel 311 is used to convert solar energy into electrical energy, and the frame 312 serves as an intermediate connection structure between the photovoltaic panel 311 and the rotating component 32. This allows the frame 312 of at least one of the two outermost photovoltaic units 31 to be slidably connected to the bracket 10, avoiding direct slid connection between the photovoltaic panel 311 and the bracket 10, thus reducing the assembly difficulty between the photovoltaic unit 31 and the bracket 10. Furthermore, the frame 312 of two adjacent photovoltaic units 31 is rotatably connected through the rotating component 32, avoiding direct connection between the photovoltaic panel 311 and the rotating component 32, thus reducing the assembly difficulty between two adjacent photovoltaic units 31.

[0040] The rotating component 32 includes a hinge, with both ends of the hinge being fixedly connected to the frame 312 of two adjacent photovoltaic units 31, respectively. The two ends of the hinge may be detachably fixedly connected to the frame 312 of the two adjacent photovoltaic units 31 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the two ends of the hinge may be non-detachably fixedly connected to the frame 312 of the two adjacent photovoltaic units 31 by riveting, welding, or gluing.

[0041] Of course, in other embodiments, the rotating member 32 may also include a rotating shaft (not shown in the figure), and the frames 312 of two adjacent photovoltaic units 31 are directly rotatably connected through the rotating shaft.

[0042] like Figures 1-4 As shown, the support frame 10 includes a lower side beam frame 11, a column 12, and a first upper side beam frame 13; the aeroponic tank 20 is installed on the lower side beam frame 11; the bottom end of the column 12 is connected to the lower side beam frame 11; the first upper side beam frame 13 is connected to the top end of the column 12; at least one of the two outermost photovoltaic units 31 is slidably connected to the first upper side beam frame 13; and the locking / unlocking member 40 is slidably connected to the first upper side beam frame 13.

[0043] The specific installation method between the aeroponic tank 20 and the lower beam frame 11 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the aeroponic tank 20 can be detachably fixedly connected to the lower beam frame 11 by at least one of the following methods: screw connection, snap connection or plug connection. Alternatively, the aeroponic tank 20 can also be non-detachably fixedly connected to the lower beam frame 11 by riveting or welding. Specifically, the lower beam frame 11 includes a first horizontal beam 111, a first vertical beam 112, a second horizontal beam 113, a second vertical beam 114, and an upright beam 115. The two ends of the first horizontal beam 111 are fixedly connected to the top of the upright beam 115, and the two ends of the first vertical beam 112 are fixedly connected to the top of the upright beam 115. The first horizontal beam 111 and the first vertical beam 112 enclose a rectangular frame. The second horizontal beam 113 is located below the first horizontal beam 111 and its two ends are fixedly connected to the upright beam 115. The second vertical beam 114 is located below the first vertical beam 112 and its two ends are fixedly connected to the upright beam 115. The second horizontal beam 113 and the second vertical beam 114 enclose another rectangular frame. In this way, the lower beam frame 11 forms a two-layer frame structure, making the structure more stable.

[0044] The specific connection method between the column 12 and the lower side beam frame 11 is not limited here; designers can design it reasonably according to actual needs. For example, the column 12 can be detachably fixedly connected to the lower side beam frame 11 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the column 12 can be non-detachably fixedly connected to the lower side beam frame 11 by riveting or welding. Similarly, the specific connection method between the column 12 and the first upper side beam frame 13 is not limited here; designers can design it reasonably according to actual needs. For example, the column 12 can be detachably fixedly connected to the first upper side beam frame 13 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the column 12 can be non-detachably fixedly connected to the first upper side beam frame 13 by riveting or welding.

[0045] By designing the lower side beam frame 11, which serves as a base for installing the aeroponic tank 20 and providing main support for the frame formed by assembling the column 12 and the first upper side beam frame 13, the column 12 provides support for the first upper side beam frame 13. The first upper side beam frame 13 is slidably connected to at least one of the two outermost photovoltaic units 31, providing a movement track for the photovoltaic unit 31. This allows the photovoltaic unit 31 to slide relative to the first upper side beam frame 13, changing the angle between two adjacent photovoltaic units 31. This enables the photovoltaic unit 31 to face the sun as much as possible, effectively improving the power generation efficiency of the photovoltaic unit 31.

[0046] like Figures 4-6 As shown, the locking / unlocking component 40 includes a handle 41 slidably connected to the first upper beam frame 13. The handle 41 is adapted to rotate under force to press against the first upper beam frame 13, thereby remaining stationary relative to the first upper beam frame 13 to lock the photovoltaic unit 31 to the first upper beam frame 13. At this time, the included angle between two adjacent photovoltaic units 31 is fixed. The handle 41 is also adapted to rotate under force to release the first upper beam frame 13, thereby moving relative to the first upper beam frame 13 to push against the photovoltaic unit 31, thereby releasing the photovoltaic unit 31 from the first upper beam frame 13. At this time, the included angle between two adjacent photovoltaic units 31 is adjustable.

[0047] Specifically, the handle 41 includes a handle body 411, a wedge 412, and a locking stud 413. The handle body 411 is rotatably connected to the wedge 412, and the wedge 412 is slidably connected to the groove of the first upper side beam frame 13. The locking stud 413 is threadedly connected to the handle body 411 and the wedge 412. Rotating the handle body 411 in the reverse direction causes the locking stud 413 to press against the side of the groove of the first upper side beam frame 13, thereby positioning the entire handle 41 on the first upper side beam frame 13. Rotating the handle body 411 in the forward direction causes the locking stud 413 to disengage from the side of the groove of the first upper side beam frame 13, thereby allowing the entire handle 41 to slide relative to the groove of the first upper side beam frame 13. The handle 41 also includes a pulley 414, which is rotatably connected to the wedge 412. When the entire handle 41 slides relative to the groove of the first upper beam frame 13, the pulley 414 rolls on the side wall of the groove of the first upper beam frame 13.

[0048] By designing the locking / unlocking component 40 as a handle 41 slidably connected to the first upper beam frame 13, when it is necessary to adjust the included angle between two adjacent photovoltaic units 31, the user rotates the handle body 411 forward, causing the handle body 411 to disengage the locking / unlocking stud 413 of the handle 41 from the side of the groove of the first upper beam frame 13, thereby allowing the entire handle 41 to slide relative to the groove of the first upper beam frame 13. At this time, the handle 41 is unlocked from the first upper beam frame 13 and is in an unlocked state. The user pushes the handle 41 so that the handle 41 can move along the groove of the first upper beam frame 13. The movement of the handle 41 relative to the first upper beam frame 13 pushes against the photovoltaic unit slidably connected to the first upper beam frame 13. When unit 31 moves, it releases the photovoltaic unit 31 onto the first upper beam frame 13, thus changing the angle between two adjacent photovoltaic units 31 until the photovoltaic unit 31 moves to the point where its light-receiving surface faces the sun. The user then stops pushing the handle 41 and rotates the handle 411 in the opposite direction, causing the handle 411 to drive the locking stud 413 of the handle 41 to press against the side of the groove of the first upper beam frame 13. At this time, the handle 41 is locked onto the first upper beam frame 13 and is in a locked state. The wedge 412 of the handle 41 limits the photovoltaic unit 31, keeping the photovoltaic unit 31 stationary relative to the first upper beam frame 13, thereby locking the photovoltaic unit 31 onto the first upper beam frame 13.

[0049] Of course, in other embodiments, the locking and unlocking component 40 may also include a locking and unlocking screw (not shown in the figure). The locking and unlocking screw passes through the frame 312 of the photovoltaic unit 31 and abuts against the groove surface of the sliding groove of the first upper beam frame 13. By tightening and loosening the locking and unlocking screw, the relative position between the photovoltaic unit 31 and the first upper beam frame 13 is changed and fixed, thereby unlocking or locking the photovoltaic unit 31 to the first upper beam frame 13.

[0050] like Figures 1-3 As shown, there are two photovoltaic modules 30, and each photovoltaic module 30 is equipped with a locking / unlocking component 40. By operating the locking / unlocking component 40 individually, the user can change the angle between two adjacent photovoltaic units 31 of the corresponding photovoltaic module 30, so that the light-receiving surfaces of the photovoltaic units 31 of the two photovoltaic modules 30 face the sun as much as possible, thereby improving the power generation efficiency of the two photovoltaic modules 30.

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the support frame 10 also includes a second upper beam frame 14, a first inclined beam 15, a top plate 16, and a side plate 17. The second upper beam frame 14 is located below the first upper beam frame 13. The width of the second upper beam frame 14 is smaller than the width of the lower beam frame 11. The bottom side of the planting board 50 is attached to the lower beam frame 11, and the top side of the planting board 50 is attached to the second upper beam frame 14. The bottom end of the first inclined beam 15 is connected to the lower beam frame 11, and the top end of the first inclined beam 15 is connected to the second upper beam frame 14. The outer edge of the top plate 16 is connected to the second upper beam frame 14. The outer edge of the side plate 17 is connected to the lower beam frame 11, the first inclined beam 15, and the second upper inclined beam, respectively. The side plate 17, the planting board 50, the aeroponic tank 20, and the top plate 16 together form a hydroponic cavity for the flow of nutrient solution.

[0052] The specific connection method between the first inclined beam 15 and the lower side beam frame 11 is not limited here; designers can design it reasonably according to actual needs. For example, the first inclined beam 15 can be detachably fixedly connected to the lower side beam frame 11 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the first inclined beam 15 can be non-detachably fixedly connected to the lower side beam frame 11 by riveting or welding. Similarly, the specific connection method between the first inclined beam 15 and the second upper side beam frame 14 is not limited here; designers can design it reasonably according to actual needs. For example, the first inclined beam 15 can be detachably fixedly connected to the second upper side beam frame 14 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the first inclined beam 15 can be non-detachably fixedly connected to the second upper side beam frame 14 by riveting or welding.

[0053] The specific connection method between the top plate 16 and the second upper side beam frame 14 is not limited here. Designers can make reasonable designs according to actual needs. For example, the top plate 16 can be detachably and fixedly connected to the second upper side beam frame 14 by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the top plate 16 can also be non-detachably and fixedly connected to the upper side beam frame by riveting or welding.

[0054] The specific connection method between the side plate 17 and the lower side beam frame 11 (or the first inclined beam 15 or the second upper side beam frame 14) is not limited here. Designers can make reasonable designs according to actual needs. For example, the side plate 17 can be detachably and fixedly connected to the lower side beam frame 11 (or the first inclined beam 15 or the second upper side beam frame 14) by at least one of the following methods: screwing, snap-fitting, or plugging. For another example, the side plate 17 can also be non-detachably and fixedly connected to the lower side beam frame 11 (or the first inclined beam 15 or the second upper side beam frame 14) by riveting or welding.

[0055] By designing the second upper side beam frame 14, the first inclined beam 15, the top plate 16, and the side plate 17, the side plate 17, the planting plate 50, and the top plate 16 are arranged together to form a photovoltaic planting box 1 with a trapezoidal cross-section. The planting plate 50 is set on both sides of the trapezoidal structure, which can improve the planting efficiency of the photovoltaic planting box 1. The side plate 17, the planting plate 50, the aeroponic pool 20, and the top plate 16 are arranged together to form a hydroponic cavity for the flow of nutrient solution, which can reduce the loss of nutrient solution and prevent the nutrient solution from being contaminated.

[0056] like Figures 1-4 As shown, the photovoltaic planting box 1 also includes a photovoltaic panel layer (not shown in the figure), which is disposed on the outer side of the side panel 17. The photovoltaic panel layer can also convert solar energy into electrical energy, so that the side of the photovoltaic planting box 1 can also convert solar energy into electrical energy when it is exposed to sunlight, thereby improving power generation efficiency.

[0057] Specifically, the photovoltaic planting box 1 also includes a clamping member 70, through which the photovoltaic panels are clamped and fixed to the outer surface of the side panel 17. The clamping member 70 can be, but is not limited to, a dovetail clip. This facilitates the installation of the photovoltaic panels to the side panel 17. Alternatively, the photovoltaic planting box 1 also includes an adhesive member (not shown in the figure), through which the photovoltaic panels are adhesively fixed to the outer surface of the side panel 17. The adhesive member can be, but is not limited to, double-sided tape. This also facilitates the installation of the photovoltaic panels to the side panel 17.

[0058] The photovoltaic planting box 1 also includes casters, which are installed on the lower side beam frame 11. The casters are designed to facilitate the handling and movement of the photovoltaic planting box 1 by users.

[0059] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the infusion assembly 60 includes an infusion pump 61, an infusion line 62, and an infusion nozzle 63. The infusion pump 61 is installed in the aeroponic tank 20; the infusion line 62 is mounted on the bracket 10 and communicates with the infusion pump 61, with the inlet of the infusion line 62 extending into the nutrient solution of the aeroponic tank 20 as the inlet end of the infusion assembly 60; the infusion nozzle 63 is connected to the infusion line 62 as the outlet end of the infusion assembly 60.

[0060] The infusion pump 61 is used to generate suction force. Under the suction force of the infusion pump 61, the nutrient solution in the aeroponic tank 20 flows from the inlet of the infusion pipeline 62 into the infusion pipeline 62, flows in the infusion pipeline 62, and finally sprays out from the nozzle of the infusion nozzle 63 to sprinkle on the roots of the plant.

[0061] Specifically, the aeroponic tank 20 includes a tank body 21 and a sealed box 22; the tank body 21 is used to hold the nutrient solution; the sealed box 22 is sealed to the tank body 21, and the infusion pump 61 is installed inside the sealed box 22. The infusion pipeline 62 includes an inlet pipe 621, a connecting pipe 622, and an outlet pipe 623; the inlet of the inlet pipe 621 extends into the nutrient solution in the tank body 21 as the inlet end of the infusion assembly 60, and the outlet of the inlet pipe 621 is connected to the inlet of the infusion pump 61; the inlet of the connecting pipe 622 is connected to the outlet of the infusion pump 61, and the outlet of the connecting pipe 622 is connected to the inlet of the outlet pipe 623; the outlet of the outlet pipe 623 is connected to the infusion nozzle 63.

[0062] The specific connection method between the infusion pump 61 and the sealed box 22 is not limited here, and designers can design it reasonably according to actual needs. For example, the infusion pump 61 can be detachably and fixedly connected to the sealed box 22 by at least one of the following methods: screw connection, snap connection, or plug connection. By designing the infusion pump 61 inside the sealed box 22, contact between the infusion pump 61 and the nutrient solution in the pool 21 can be avoided, preventing the nutrient solution from corroding the infusion pump 61 and extending the service life of the infusion pump 61.

[0063] There can be multiple nutrient outlet pipes 623, arranged in layers from top to bottom, with the number of pipes 623 in different layers being the same or different. Based on this, the connecting pipe 622 has multiple outlets, each connected to one of the multiple nutrient outlet pipes 623 via connectors. Each nutrient outlet pipe 623 has multiple outlets spaced apart, each connected to one of multiple infusion nozzles 63. This design ensures that the nutrient solution sprayed from the infusion nozzles 63 can cover the plant's root system as comprehensively as possible, allowing for better nutrient absorption by the roots.

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the support 10 also includes a second inclined beam 18a, a first support beam 18b, and a second support beam 18c; the bottom end of the second inclined beam 18a is connected to the lower side beam frame 11, and the top end of the second inclined beam 18a is connected to the second upper side beam frame 14; both ends of the first support beam 18b are connected to the first inclined beam 15; both ends of the second support beam 18c are connected to the second inclined beam 18a. A connecting pipe 622 is fixed to the first support beam 18b, and a liquid outlet pipe 623 is fixed to the second support beam 18c.

[0065] The specific connection method between the second inclined beam 18a and the lower beam frame 11 (or the second upper beam frame 14) is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the second inclined beam 18a can be detachably and fixedly connected to the lower beam frame 11 (or the second upper beam frame 14) by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the second inclined beam 18a can also be non-detachably and fixedly connected to the lower beam frame 11 (or the second upper beam frame 14) by riveting or welding.

[0066] The specific connection method between the first support beam 18b and the first inclined beam 15 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the first support beam 18b can be detachably and fixedly connected to the first inclined beam 15 by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the first support beam 18b can also be non-detachably and fixedly connected to the first inclined beam 15 by riveting or welding.

[0067] The specific connection method between the second support beam 18c and the second inclined beam 18a is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the second support beam 18c can be detachably and fixedly connected to the second inclined beam 18a by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the second support beam 18c can also be non-detachably and fixedly connected to the second inclined beam 18a by riveting or welding.

[0068] The specific installation method between the connecting pipe 622 and the first support beam 18b is not limited here; designers can design it reasonably according to actual needs. For example, the connecting pipe 622 can be fixed to the first support beam 18b by, but is not limited to, components such as straps, wires, or clamps. Similarly, the specific installation method between the outlet pipe 623 and the second support beam 18c is not limited here; designers can design it reasonably according to actual needs. For example, the outlet pipe 623 can be fixed to the second support beam 18c by, but is not limited to, components such as straps, wires, or clamps.

[0069] By designing a second inclined beam 18a, which connects to the second support beam 18c and also acts as a reinforcing rib to enhance the overall structural strength of the support 10; by designing a first support beam 18b, which serves to fix the connecting pipe 622 and also acts as a reinforcing rib to enhance the overall structural strength of the support 10; and by designing a second support beam 18c, which serves to fix the outlet pipe 623 and also acts as a reinforcing rib to enhance the overall structural strength of the support 10.

[0070] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the infusion line 62 also includes a drain pipe 624, with one end of the drain pipe 624 connected to the connecting pipe 622 and the other end of the drain pipe 624 extending outside the pool body 21. The infusion assembly 60 also includes a spray valve 64 and a drain valve 65; the spray valve 64 is located on the connecting pipe 622; and the drain valve 65 is located on the drain pipe 624.

[0071] Among them, the spray valve 64 is used to control the opening and closing of the connecting pipe 622; the drain valve 65 is used to control the opening and closing of the drain pipe 624. The spray valve 64 and drain valve 65 can be manual valves. When it is necessary to spray nutrient solution on the plant roots, the user can directly operate the spray valve 64 to open and the drain valve 65 to close manually. At this time, the nutrient solution in the pool 21 flows into the inlet pipe 621 from the inlet under the suction force of the infusion pump 61, flows through the infusion pump 61, the connecting pipe 622 and the outlet pipe 623 in sequence, and finally sprays out from the infusion nozzle 63 to sprinkle on the plant roots. When it is necessary to replace the nutrient solution in the pool 21, the user can directly operate the spray valve 64 to close and the drain valve 65 to open manually. At this time, the nutrient solution in the pool 21 flows into the inlet pipe 621 from the inlet under the suction force of the infusion pump 61, flows through the infusion pump 61, the connecting pipe 622 and the drain pipe 624 in sequence, and finally flows out from the outlet of the drain pipe 624 to the outside of the pool 21. The spray valve 64 and drain valve 65 can also be automatic valves. The photovoltaic planting box 1 also includes a remote control. When it is necessary to spray nutrient solution on the plant roots, the user presses the "spray" switch on the remote control. The infusion pump 61 starts, the spray valve 64 is opened, and the drain valve 65 is closed. At this time, the nutrient solution in the tank 21 flows from the inlet of the infusion pipe 621 into the infusion pipe 621 under the suction force of the infusion pump 61, flows through the infusion pump 61, the connecting pipe 622 and the outlet pipe 623 in sequence, and finally flows out of the infusion pipe 621. The nozzle 63 sprays the solution onto the plant roots. When the nutrient solution in the pool 21 needs to be replaced, the user presses the "drain" switch on the remote control. The infusion pump 61 starts, the spray valve 64 closes, and the drain valve 65 opens. At this time, the nutrient solution in the pool 21 flows from the inlet of the infusion pipe 621 into the infusion pipe 621 under the suction force of the infusion pump 61. It then flows through the infusion pump 61, the connecting pipe 622, and the drain pipe 624 in sequence, and finally flows out of the pool 21 from the outlet of the drain pipe 624.

[0072] like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the sealed box 22 includes a box body 221 and a cover 222; the box body 221 is located inside the tank of the pool body 21 and is sealed to the pool wall of the pool body 21, and the opening of the box body 221 penetrates one side of the pool wall of the pool body 21; the cover 222 is connected to the box body 221 to open or close the opening of the box body 221. The liquid discharge pump is located in the cavity formed by the box body 221 and the cover 222.

[0073] The lid 222 can be rotatably connected to the box 221, in which case the lid 222 opens or closes the box opening of the box 221 by rotating; the lid 222 can also be slidably connected to the box 221, in which case the lid 222 opens or closes the box opening of the box 221 by sliding.

[0074] By designing the opening of the housing 221 to penetrate one side of the pool wall of the pool body 21, and the cover 222 connected to the housing 221 to open or close the opening of the housing 221, it is convenient for users to repair or replace the infusion pump 61 from outside the pool body 21 by opening and closing the cover 222.
