[0017] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0018] The embodiment of the present invention provides a photovoltaic bracket that can be fully rotated and digitally adjusted. Figures 1 to 3 As shown, the photovoltaic bracket includes: A retractable column is set on the ground; A support frame, located above the retractable column, for supporting the photovoltaic module 1; A rotatable column, the bottom end of which is connected to the top end of the telescopic column, and the top end of which is rotatably connected to the bottom of the support frame, for driving the support frame to rotate horizontally; The telescopic member 6 is located on one side of the rotatable column, one end of which is rotatably connected to the bottom of the support frame, and the other end of which is rotatably connected to the side wall of the rotatable column, and is used to drive the support frame to tilt and rotate during the telescopic process.

[0019] Specifically, the support frame and the telescopic column are not directly connected, but are connected to each other through a rotatable column.

[0020] By setting a rotatable column, the photovoltaic component 1 can be rotated 360 degrees horizontally to track the changes in the azimuth of the sun; by setting a retractable part 6, the inclination of the photovoltaic component 1 can be adjusted to meet the optimal solar radiation angle; by setting a retractable column, the height of the photovoltaic component 1 can be adjusted to avoid the photovoltaic component 1 being blocked. Through the azimuth, inclination and height, the photovoltaic component 1 can track the sun, thereby greatly improving the power generation efficiency of the photovoltaic system.

[0021] At the same time, through refined azimuth, inclination and height adjustment, the ability of the photovoltaic module 1 to resist adverse strong wind loads can also be enhanced. When encountering extreme strong winds, the photovoltaic bracket can quickly and efficiently lower the height of the photovoltaic module 1 and level the inclination of the photovoltaic module 1, thereby effectively reducing the load on the photovoltaic module 1 and preventing its structure from being damaged due to excessive load, thereby ensuring the safe operation of the photovoltaic system and improving the stability of the photovoltaic system.

[0029] Specifically, the diagonal brace 5 is connected to the diagonal beam 3 through a connecting member 4 .

[0030] By connecting a plurality of diagonal braces 5 to the connecting plate 10 to form an umbrella-like structure, the force transmitted from the plurality of photovoltaic modules 1 to the purlins 2 can be concentratedly transmitted to the connecting plate 10 to ensure the overall stability of the supporting frame.

[0031] Specifically, the support frame may further include: One end of the support rod 9 is connected to the top of the connecting plate 10 , and the other end is connected to the bottom of the inclined beam 3 .
