[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that terms such as "end", "upper", "lower", "side", "top", "bottom", "length", "inside", and "surface" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present invention.

[0026] In a photovoltaic open-air planting system, after the installation density of the solar panels is determined, the coverage rate of the photovoltaic system can be adjusted by changing the orientation, tilt angle and other parameters of the photovoltaic panels. Selecting an appropriate photovoltaic coverage rate can achieve the best power generation efficiency, and is conducive to the growth of crops, maximizing economic benefits. In the prior art, it is difficult to synchronously adjust an array of photovoltaic panels arranged and installed in an area, and the construction and maintenance costs of achieving synchronous adjustment are relatively high. Based on this, the present embodiment provides a photovoltaic installation structure with adjustable photovoltaic coverage, which can synchronously adjust the inclination angle of the photovoltaic panels of each photovoltaic unit, and has the advantages of simple structure and convenient adjustment.

[0027] See also Figure 1As shown, the photovoltaic installation structure with adjustable photovoltaic coverage includes a plurality of photovoltaic units 100 arranged transversely, and each photovoltaic unit 100 is connected by a transmission shaft 300. A driving component 200 is installed at one end of the transmission shaft 300. The driving component 200 uses a motor to synchronously adjust the inclination angle of the photovoltaic panel 9 of each photovoltaic unit 100, and facilitates the adjustment of the inclination angle of each photovoltaic panel 9.

[0028] Specifically, see Figure 2-Figure 4 As shown, the photovoltaic unit 100 includes a bracket 1, a mounting frame 6 and a photovoltaic panel 9. The mounting frame 6 is hinged to the upper end of the bracket 1 by a hinge, and the photovoltaic panel 9 is fixed to the mounting frame 6 by bolts so as to rotate with the mounting frame 6.

[0029] The bracket 1 is also equipped with a screw adjustment mechanism for adjusting the inclination of the photovoltaic panel 9. The screw adjustment mechanism includes a screw 3, a slider 4 and a connecting rod 5. The screw 3 is arranged in the height direction and is rotatably mounted on the bracket 1 through a shaft seat. The slider 4 is threadedly connected to the screw 3. One end of the connecting rod 5 is hinged to the peripheral side of the slider 4, and the other end of the connecting rod 5 is hinged to the mounting frame 6. The transmission shaft 300 is rotatably mounted on the bracket 1 through a shaft seat and is located at the lower end of the screw 3. A first bevel gear 7 is fixedly mounted on the lower end of the screw 3. A plurality of second bevel gears 8 are fixedly mounted on the peripheral side of the transmission shaft 300. The first bevel gear 7 is meshed with the second bevel gear 8.

[0030] During operation, the angle of the photovoltaic panel 9 can be adjusted according to the illumination characteristics of the crops planted below the photovoltaic unit 100 and the seasonal movement characteristics of the sun. For example, at noon in summer, the sun's irradiation causes the moisture of crops and soil to be lost rapidly. At this time, the transmission shaft 300 is driven by the motor to rotate, and then the lead screw 3 of each photovoltaic unit 100 is driven to adjust the photovoltaic panel 9 of each photovoltaic unit 100 to a state perpendicular to the light. At this time, the photovoltaic panel 9 can be guaranteed to have the best shading effect, that is, the maximum photovoltaic coverage rate. Reduce the evaporation of moisture from crops and soil under the photovoltaic panel 9. For periods with strong light intensity such as morning and evening, or crops that like light, the light intensity and duration of the crops should be fully guaranteed. By adjusting the photovoltaic panel 9 to an angle with the sun's rays, a certain light transmittance can be guaranteed. It is worth noting that in order to ensure that the photovoltaic panel 9 has a certain power generation capacity, the photovoltaic panel 9 should be avoided as much as possible from being parallel to the sun's rays, in order to obtain the maximum photovoltaic and agricultural comprehensive benefits.

[0031] In a preferred embodiment of the present invention, a foundation pile 2 is provided for fixing the photovoltaic unit 100, and the bracket 1 is fixed on the foundation pile 2. The foundation pile 2 can be made of cement casting, which has low construction cost and can fully ensure the stability of the photovoltaic unit when installed outdoors. At the same time, the foundation pile 2 occupies a small area, ensuring the planting area of ​​crops. And the cement foundation piles 2 are arranged in rows, which is convenient for the later crop management.
