DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example 1: Figures 1 to 4 The illustrated photovoltaic support, with a single column 12 for mountain use and adjustable mounting, includes a base plate 1 fixed to a mounting surface on the mountain. Base plate 1 is a rectangular plate structure with mounting holes 11 at its four corners, through which bolts pass to secure base plate 1 to the mountain. An upwardly extending column 12 is connected above base plate 1. Column 12 adjusts its tilt angle by adjusting the angle between itself and base plate 1, thereby changing the support angle for photovoltaic panel 4. Its height is adjusted by a lifting assembly 3 to adapt to highly uneven mountain terrain. Column 12 is fixedly connected to photovoltaic panel 4 from above, providing stable support.

[0028] In this way, multiple photovoltaic brackets can be used to stably support the photovoltaic panel 4 so that it can be installed on a mountain with complex terrain, and the inclination angle and support height of a single photovoltaic bracket can be adjusted separately, which has a strong adaptability to complex terrain. The angle between the column 12 and the base plate 1 is changed by adjusting the component 2, thereby changing the support angle of the photovoltaic panel 4, and the inclination angle of the column 12 at different positions on the mountain is adaptively adjusted to match the changes in the slope of the mountain, thereby ensuring the flatness of the installation of the photovoltaic panel 4 and the support stability; and the height of the column 12 is adjusted by the lifting component 3, and the height of the column 12 at different positions on the mountain is adaptively adjusted to adapt to the highly uneven mountain terrain, thereby further ensuring the flatness of the installation of the photovoltaic panel 4 and the support stability, and comprehensively considering the height and inclination of the photovoltaic bracket from the terrain structure, making the installation of the photovoltaic panel 4 more convenient and effective, and improving the support stability.

[0029] Example 2: Based on Example 1, the adjustment component 2 is preferably designed as follows: Figures 2 to 3 As shown, the adjustment assembly 2 includes a gear 21 and a rack 22. The gear 21 is fixed to the side of the lower portion of the column 12 and is parallel to it. Therefore, when the gear 21 rotates, it drives the column 12 to rotate on the same vertical plane, adaptively adjusting its tilt angle. The rack 22 is located below the gear 21 and its upper surface engages with the gear 21. The rack 22 is parallel to the base plate 1 and is movably connected to the base plate 1. The rack 22 can move back and forth horizontally on the base plate 1. When the rack 22 moves, it drives the gear 21 to rotate. The rotation of the gear 21 drives the column 12 to adjust its tilt angle, thereby meeting the installation requirements of the photovoltaic panel 4 on different terrains.

[0030] Furthermore, support plates 13 are respectively provided on both sides of the column 12. The two support plates 13 are opposite to each other and are vertically fixed on the surface of the base plate 1 and are connected together by a connecting shaft 14. The two ends of the connecting shaft 14 are respectively connected to the support plates 13 through bearings 5. The bearings 5 ​​are respectively fixed in the support plates 13. The connecting shaft 14 can rotate freely under the action of the bearings 5 ​​and remains stably connected to the support plates 13; the column 12 is located between the two support plates 13, and the connecting shaft 14 horizontally passes through the bottom of the column 12 and the axis of the gear 21 and is fixedly connected to the two. Therefore, when the gear 21 rotates, it drives the connecting shaft 14 to rotate, thereby driving the column 12 to adjust the inclination angle.

[0031] Furthermore, a threaded through hole 223 is provided in the rack 22 along its length direction, and the threaded rod 24 is cooperated with the threaded through hole 223 and passes through the rack 22 from the threaded through hole 223. By rotating the threaded rod 24, the rack 22 can move back and forth on the threaded rod 24, thereby driving the gear 21 to rotate; the rack 22 is arranged in the frame 23, and the frame 23 is a rectangular box structure with its bottom fixed on the base plate 1. The rack 22 is connected to the frame 23 through the threaded rod 24, that is, the two ends of the threaded rod 24 are connected to the side walls of the frame 23 through bearings 5, and the bearings 5 ​​are fixed in the side walls of the two ends of the frame 23. The threaded rod 24 can rotate freely under the action of the bearings 5 ​​and remain stably connected to the frame 23. One end of the threaded rod 24 extends out of the side wall of the frame 23 and is connected to the handwheel 25 shaft transmission, that is, one end of the threaded rod 24 extends out from the bearing 5 on the side wall of the frame 23 and is fixedly connected to the axis of the handwheel 25. A support rod 251 extending vertically outward is fixed to the outer side of the handwheel 25. By rotating the support rod 251, the handwheel 25 can be driven to rotate, thereby driving the threaded rod 24 to rotate.

[0032] When adjusting the inclination angle of the column 12, the angle between the column 12 and the mountain slope is adjusted according to the slope. First, turn the handwheel 25 to drive the threaded rod 24 to rotate, and the threaded rod 24 drives the rack 22 to move back and forth, and then the rack 22 drives the gear 21 to rotate. The gear 21 drives the column 12 to swing along with the gear 21 through the connecting shaft 14 to adjust the angle of the column 12. The column 12 can change the support angle of the photovoltaic panel 4 to adapt to the changes in the slope in the mountain.

[0033] Example 3: Based on Example 1, the lifting component 3 is optimally designed, such as Figure 2 and Figure 4 As shown, the lifting assembly 3 includes a lifting column 31, and a cavity 121 is provided in the upper part of the column 12. The lifting column 31 is inserted into the cavity 121 from the top of the column 12 and is fixedly connected to the side wall of the column 12. The lifting column 31 can adjust the length of the insertion into the column 12 to change the overall height of the photovoltaic bracket. The specific fixing method is that the front and rear sides of the column body of the lifting column 31 are symmetrically arranged with a number of threaded holes 311 along its length direction, and the tops of the front and rear sides of the column body of the column 12 are respectively installed with positioning bolts 33 passing through the side walls thereof. The fixed ends of the positioning bolts 33 are respectively passed through the corresponding threaded holes 311 to fix the lifting column 31 on the column 12. The top of the lifting column 31 is then fixedly connected to the bottom of the photovoltaic panel 4, and the column 12 stably supports the photovoltaic panel 4 through the lifting column 31.

[0034] During use, the photovoltaic panel 4 is fixed to the lifting column 31, and the height of the lifting column 31 extending from the column 12 is adjusted to meet the installation requirements. Then, the positioning bolt 33 is rotated and screwed into the threaded hole 311 to fix the lifting column 31 at the appropriate height, ensuring that the photovoltaic panel 4 remains parallel to the mountain slope. By providing a movable and adjustable lifting column 31 within the cavity 121 of the column 12, it can adapt to highly uneven mountain terrain, further ensure the flatness of the photovoltaic panel 4 installation, and make subsequent adjustments more convenient.

[0035] Furthermore, a U-shaped plate 34 fixed to the side wall of the column 12 is provided between the column 12 and the positioning bolt 33. The two sides of the U-shaped plate 34 are vertically fixed to the side walls of the column 12. The positioning bolt 33 passes through the top surface of the U-shaped plate 34, the side wall of the column 12 and the threaded hole 311 of the lifting column 31 in sequence to fix the lifting column 31 on the column 12. The setting of the U-shaped plate 34 further improves the connection stability between the lifting column 31 and the column 12.

[0036] Furthermore, symmetrical positions on the upper and left sides of the column 12 extend along its length, respectively. A symmetrical position on the lower and left sides of the lifting column 31 is fixed with a symmetrical position on each of the lower and left sides. The position blocks 312 cooperate with the position blocks 122. That is, the position blocks 312 on the left and right sides of the lifting column 31 engage within the position blocks 122 on the left and right sides of the column 12 and can move up and down within the position blocks 122. The position blocks 122 communicate with the cavity 121 within the column 12. During use, the position blocks 312 on both sides of the lifting column 31 are first engaged within the position blocks 122. The lifting column 31 is then pulled to adjust its relative position to the column 12 according to the ground height. Once the height is determined, the lifting column 31 is fixed. The position blocks 312 that cooperate with the position blocks 312 further improve the connection stability between the lifting column 31 and the column 12, and also enhance the support stability of the column 12 for the photovoltaic panel 4.

Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the technical concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
