Technical Field

[0001] This utility model belongs to the field of photovoltaic agricultural technology, and in particular relates to a shade-loving plant planting system that also generates photovoltaic power. Background Technology

[0002] Epimedium sagittatum is a highly valuable traditional Chinese medicine. It is a shade-loving plant, best suited for growth under forest canopies or in shady environments. Traditional non-forest cultivation requires the construction of specialized shade structures, which undoubtedly increases planting costs. Therefore, it is necessary to improve the existing Epimedium sagittatum cultivation system. Summary of the Invention

[0003] The main purpose of this invention is to provide a shade-loving plant planting system that combines photovoltaic power generation. The system utilizes the shading environment generated by rotating photovoltaic panels to provide shade-loving plants such as Epimedium brevicornu under the forest canopy, while the sprinkler system can provide a suitable humidity environment for the soil in which the plants are planted. At the same time, the photovoltaic panels generate electricity to increase economic benefits.

[0004] Therefore, the present invention provides a shade-loving plant planting system that also generates photovoltaic power, including a photovoltaic sun-tracking bracket and a photovoltaic panel installed on the photovoltaic sun-tracking bracket. The photovoltaic sun-tracking bracket is installed on the planting ground, and shade-loving plants are planted on the planting ground below the photovoltaic panel. A sprinkler system is installed on the photovoltaic sun-tracking bracket, and a soil moisture meter is installed in the planting ground. The soil moisture meter, the sprinkler system, and the photovoltaic sun-tracking bracket are all connected to a controller.

[0005] Specifically, the photovoltaic tracking bracket includes a purlin frame, a support frame, and a rotation drive component. The support frame is fixedly installed on the planting ground, and multiple photovoltaic panels are fixedly installed on the purlin frame to form a photovoltaic array. The purlin frame is rotatably connected to the top of the support frame via a rotating shaft. The rotation drive component is used to drive the photovoltaic panels to rotate around the support frame, and the controller is connected to the rotation drive component.

[0006] Specifically, the rotary drive component is a double-acting electro-hydraulic cylinder, one end of which is hinged to the support frame and the other end is hinged to the purlin frame.

[0007] Specifically, multiple support frames are arranged equidistantly along the north-south direction on the planting ground, and at least one of the support frames is equipped with the rotary drive component.

[0008] Specifically, drainage ditches are provided on the east and west sides of the planting site where the shade-loving plants are located.

[0009] Specifically, the sprinkler system includes multiple nozzles arranged on the back of the purlin frame. The nozzles are connected to a water tank via pipes. A water pump is installed on the pipes. The water pump and the soil moisture meter are both connected to the controller.

[0010] Specifically, the shade-loving plant is Epimedium sagittatum.

[0011] Compared with the prior art, this utility model has the following beneficial effects: The controller controls the photovoltaic sun-tracking bracket to drive the photovoltaic panel to change its posture (sun-tracking) according to the sun's position, so that the light-receiving surface of the photovoltaic panel receives vertical sunlight in real time, thereby effectively increasing power generation. At the same time, the shading environment generated by the rotating photovoltaic panel provides shade conditions under the forest for shade-loving plants. The soil moisture meter measures the soil moisture in real time and feeds it back to the controller. Based on the measured humidity data, the controller controls the operation of the sprinkler system to provide a suitable growth humidity environment for shade-loving plants, thereby achieving the purpose of increasing economic benefits.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] See Figures 1-3 A shade-loving plant planting system that also generates photovoltaic power includes a photovoltaic sun-tracking bracket 1 and a photovoltaic panel 2 installed on the photovoltaic sun-tracking bracket 1. The photovoltaic sun-tracking bracket 1 is installed on a planting site 3. Shade-loving plants 4 are planted on the planting site 3 below the photovoltaic panel 2. A sprinkler system 5 is installed on the photovoltaic sun-tracking bracket 1. A soil moisture meter 6 is installed in the planting site 3. The soil moisture meter 6, the sprinkler system 5, and the photovoltaic sun-tracking bracket 1 are all connected to a controller 8.

[0018] In this embodiment, the controller 8 controls the photovoltaic tracking bracket 1 to drive the photovoltaic panel 2 to change its posture (tracking the sun) according to the sun's position, so that the light-receiving surface of the photovoltaic panel 2 receives vertical sunlight in real time, thereby effectively increasing power generation. At the same time, the shading environment generated by rotating the photovoltaic panel 2 provides shade-loving plants 4 under the forest canopy. The soil moisture meter 6 measures the soil moisture in real time and feeds it back to the controller 8. Based on the measured humidity data, the controller 8 controls the sprinkler system 5 to work, providing a suitable growth humidity environment for the shade-loving plants 4, thereby achieving the purpose of increasing economic benefits.

[0019] See Figure 1 , Figure 3 and Figure 4 Specifically, the photovoltaic tracking bracket 1 includes a purlin frame 101, a support frame 102, and a rotary drive component 103. The support frame 102 is fixedly installed on the planting area 3, and multiple photovoltaic panels 2 are fixedly installed on the purlin frame 101 to form a photovoltaic array. The purlin frame 101 is rotatably connected to the top of the support frame 102 through a rotating shaft 12. The rotary drive component 103 is used to drive the photovoltaic panels 2 to rotate around the support frame 102. The controller 8 is connected to the rotary drive component 103. The rotary drive component 103 is a double-acting electro-hydraulic cylinder. One end of the double-acting electro-hydraulic cylinder is hinged to the support frame 102, and the other end is hinged to the purlin frame 101.

[0020] In this embodiment, the solar tracking system composed of the photovoltaic tracking bracket 1 and the controller 8 employs an apparent solar trajectory tracking method. The apparent solar trajectory is calculated by the calculation program in the controller 8 based on the position parameters of the photovoltaic system, determining the correspondence between the time and the direction and altitude of the sun. This, in turn, controls the rotating drive component 103 to rotate the photovoltaic panel 2, achieving the tracking purpose. Of course, photoelectric detection tracking or a combination of both can also be used. The above-described solar tracking system construction is a conventional existing technology and is not the focus of this application's improvement; therefore, it will not be elaborated upon further.

[0021] See Figure 3 To provide stable support for the photovoltaic panel 2, multiple support frames 102 are arranged at equal intervals along the north-south direction on the planting site 3, and at least one support frame 102 is equipped with the aforementioned rotary drive component 103. To adapt to different terrain installation requirements, the length of the support frame 102 can be flexibly adjusted.

[0022] See Figures 1-3 In addition, drainage ditches 7 are provided on the east and west sides of the planting site 3, located on the shade-loving plant 4. The shade-loving plant 4 prefers moist but not waterlogged soil. The drainage ditches 7 are designed to precisely control the soil moisture in the root zone through active drainage, simulating the loose and well-drained soil conditions in its native forest environment, effectively maintaining a moist but not wet state. Among them, the shade-loving plant 4 can be Epimedium sagittatum, but it can also be other plants.

[0023] See Figure 1 and Figure 3 Specifically, the sprinkler system 5 includes multiple nozzles 501 arranged on the back of the purlin frame 101. The nozzles 501 are connected to a water tank via pipes 502, and a water pump is installed on the pipes 502. The water pump and the soil moisture meter 6 are both connected to the controller 8. In this embodiment, the soil moisture meter 6 measures whether the soil moisture is within the set range. When the soil moisture is too low than the design value, the controller 8 controls the water pump to work, and the water pump sprays the water in the water tank through the nozzles 501 onto the planting area 3 of the shade-loving plants 4, thereby increasing the soil moisture.

[0024] See Figure 1 and Figure 3 It is understood that multiple nozzles 501 are arranged in rows on the back of the purlin frame 101, with each row including multiple nozzles 501 arranged along the north-south direction. The number of rows of nozzles 501 can be adjusted according to actual needs. For example, in this embodiment, the number is one row, as long as the spray can cover the shade-loving plants 4 below. See Figure 4 and Figure 5 The top of the support frame 102 is fixedly installed with a bearing seat 9. The rotating shaft 12 passes through the bearing seats 9 on each support frame 102 in sequence. The double-acting electro-hydraulic cylinder is hinged to the rocker arm 10 on the rotating shaft. The support frame 102 is fixed to the cement base 11 in the planting area 3 by bolt assembly.
