[0021] As Figures 1 - 2 As shown, the present utility model provides a photovoltaic panel mounting bracket applicable to mountainous areas, including: a cast-in-place pile 1 fixed on the mountain, a support column 2 arranged at the top of the cast-in-place pile 1, a first ear seat 3 arranged at the top of the support column 2, a second ear seat 4 hinged on the first ear seat 3, a support plate 5 arranged on the second ear seat 4, the support plate 5 rotates in the vertical plane, and a photovoltaic panel 6 is fixedly connected to the top of the support plate 5;

[0022] Among them, one end of the bottom surface of the support plate 5 is provided with a first pull ring 7, the upper outer wall of the support column 2 is provided with a spring connection seat 8, a spring 9 is arranged between the first pull ring 7 and the spring connection seat 8, the other end of the bottom surface of the support plate 5 is provided with a second pull ring 10, a self-locking hand winch 11 is arranged on the lower outer wall of the support column 2, and the rope on the self-locking hand winch 11 is connected to the second pull ring 10 to control the elevation angle of the photovoltaic panel 6;

[0023] The support column 2 is rotatably connected to the top of the cast-in-place pile 1 around its own axis, and a handle 12 is further arranged on the lower side wall of the support column 2 along the radial direction of the support column 2 to control the orientation of the photovoltaic panel 6.

[0024] Specifically, the cast-in-place pile 1 is vertically and fixedly arranged on the mountain. At the top of the cast-in-place pile 1, a support column 2 is coaxially rotatably connected. The first ear seat 3 is connected to the top of the support column 2 by welding or bolts. The axis of the ear hole on the first ear seat 3 is horizontally arranged. The second ear seat 4 is hinged on the first ear seat 3. In this way, the second ear seat 4 can rotate in a vertical plane perpendicular to the axis of the ear hole on the first ear seat 3. The support plate 5 is connected to the second ear seat 4 by welding or screws. The photovoltaic panel 6 is connected to the support plate 5 by screws. When the second ear seat 4 rotates, it can drive the photovoltaic panel 6 to rotate together, thereby realizing the adjustment of the elevation angle of the photovoltaic panel 6.

[0025] Specifically, the first pull ring 7, the spring connection seat 8, the spring 9, the second pull ring 10, and the self-locking hand winch 11 are all arranged on the rotating surface of the photovoltaic panel 6. One end of the support plate 5 is pulled by the spring 9 to apply a force to the support plate 5 to make it rotate in the clockwise direction. The rope on the self-locking hand winch 11 pulls the other end of the support plate 5 to apply a force to the support plate 5 to make it rotate in the counterclockwise direction. By rotating the self-locking hand winch 11 to overcome the torque generated by the tension of the spring 9, the photovoltaic panel 6 is stopped at the preset elevation angle, and locking the self-locking hand winch 11 can complete the adjustment of the elevation angle of the photovoltaic panel 6. When the change of seasons causes the change of the solar incident angle, the rope of the self-locking hand winch 11 can be loosened, or the rope of the self-locking hand winch 11 can be tightened continuously to readjust the elevation angle of the photovoltaic panel 6.

[0026] Specifically, since the support column 2 is coaxially rotatably connected to the cast-in-place pile 1, the support column 2 can be rotated by rotating the handle 12. The photovoltaic panel 6, the support plate 5, the first ear seat 3, the second ear seat 4, the first pull ring 7, the spring connection seat 8, the spring 9, the second pull ring 10, and the self-locking hand winch 11 are all arranged on the support column 2. The rotation of the support column 2 can drive the photovoltaic panel 6 to rotate, thereby adjusting the orientation of the photovoltaic panel 6.

[0027] In the above embodiment, the elevation angle of the photovoltaic panel 6 can be adjusted by rotating the self-locking hand winch 11. After the adjustment is completed, the self-locking hand winch 11 can also self-lock and fix the elevation angle of the photovoltaic panel 6. The orientation of the photovoltaic panel 6 can be adjusted by rotating the handle 12. The operation is simple. At the same time, the installation positions of the self-locking hand winch 11 and the handle 12 are close. Therefore, the staff can operate at the same position, and the use experience is better.

[0028] In another embodiment, the support column 2 can be coaxially rotatably connected to the top of the cast-in-place pile 1 in the following way: a first connecting plate 13 is arranged at the top of the cast-in-place pile 1. A second connecting plate 14 is bolted to the first connecting plate 13. A core tube 15 coaxial with the cast-in-place pile 1 is arranged on the second connecting plate 14. The support column 2 is coaxially sleeved outside the core tube 15. A bearing 16 is arranged between the support column 2 and the core tube 15.

[0029] Specifically, the cast-in-place pile 1, the support column 2, and the core pipe 15 can all be made of steel pipes and are coaxially arranged. The cast-in-place pile 1 serves as a foundation pile, and its outer diameter is larger than that of the support column 2. The lower end of the core pipe is welded to the second connecting plate. Of course, the cast-in-place pile 1 can also be a square steel pipe, and the inscribed circle diameter of the square steel pipe is not less than the outer diameter of the support column 2. A bearing 16 is arranged between the support column 2 and the core pipe 15, so that the support column 2 can be accurately coaxially sleeved outside the core pipe 15. The cast-in-place pile 1, the support column 2, and the core pipe 15 are coaxially arranged, and the center of gravity is on the same vertical line, without generating torque, which is beneficial to the stability of the bracket.

[0030] When the above-mentioned embodiment is used, by rotating the handle 12, the photovoltaic panel 6 on the support column 2 can be driven to rotate, and the operation is simple.

[0031] In another embodiment, a fixed pulley is arranged on the outer wall of the upper part of the support column 2, and the rope on the self-locking hand winch 11 bypasses the fixed pulley and is connected to the second pull ring 10.

[0032] Since there are trees in the mountainous area, if the rope on the self-locking hand winch 11 is directly connected to the second pull ring 10, the deflection angle of the rope relative to the vertical direction is large and it is easily interfered by tree branches. Therefore, in the above-mentioned embodiment, a fixed pulley is arranged to converge the rope to avoid the interference of tree branches on the rope.

[0033] In another embodiment, an annular groove adapted to the lower end of the support column 2 is arranged on the upper surface of the second connecting plate 14, and lubricating grease is arranged in the annular groove. By arranging the annular groove and the lubricating grease, the lower end of the support column 2 can be limited, and the frictional resistance between the support column 2 and the second connecting plate 14 can be reduced, and the wear of both can be reduced.

[0034] In another embodiment, the rope on the self-locking hand winch 11 is a plastic-coated steel wire rope. Since there are rodent small animals in the mountainous area, using a steel wire rope can prevent small animals from biting off the rope, and at the same time, the plastic-coated shell can reduce the erosion of rainwater on the steel wire rope.

[0035] In another embodiment, galvanized layers are arranged on the surfaces of the cast-in-place pile 1, the support column 2, the first ear seat 3, the second ear seat 4, the support plate 5, the first pull ring 7, the second pull ring 10, the spring 9, and the spring connecting seat 8. Arranging the galvanized layer can enhance the corrosion resistance of the components such as the cast-in-place pile 1, the support column 2, the first ear seat 3, the second ear seat 4, the support plate 5, the first pull ring 7, the second pull ring 10, the spring 9, and the spring connecting seat 8, and extend their service life.

[0036] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples here.
