DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] like Figure 1 As shown, an embodiment of the present invention provides a corner bracing support system, the support system comprising:

[0036] A main beam 100, wherein the main beam 100 is supported by a column 300, and the main beam 100 and the column 300 are fixedly connected;

[0037] A plurality of support brackets 200 provided on the main beam 100 are used to fix the photovoltaic panels. The support brackets 200 include a photovoltaic support frame 210, a hanging plate 230 and an oblique support 240. The photovoltaic support frame 210 and the hanging plate 230 are located on the upper and lower sides of the main beam 100. The photovoltaic support frame 210 is a flat frame structure. The hanging plate 230 is rotatably connected to the main beam 100. The hanging plate 230 and the photovoltaic support frame 210 are fixedly connected by oblique supports 240. The oblique supports 240 are distributed on both sides of the hanging plate 230.

[0038] An adjusting unit is arranged on the main beam 100, and the adjusting unit includes a driving component and a braking component 600. The braking component 600 is fixedly connected to the main beam 100, and the braking component 600 is used to brake the hanger 230 so that it cannot rotate. The driving component is used to drive the hanger 230 to rotate on the main beam 100 to adjust the angle of the photovoltaic support frame 210.

[0039] In this embodiment, the photovoltaic support frame 210, the hanger plate 230 and the inclined support 240 form a trapezoidal structure. Due to the fixed connection between the photovoltaic support frame 210, the hanger plate 230 and the inclined support 240, the photovoltaic panel is installed on the photovoltaic support frame 210. When the hanger plate 230 rotates, the photovoltaic support frame 210 rotates around the main beam 100 driven by the column 300, so as to adjust the angle between the photovoltaic panel and the sunlight. When adjusting the angle of the photovoltaic panel, the driving assembly drives the hanger plate 230 to rotate around the main beam 100. When the adjustment of the angle of the photovoltaic panel stops, the braking unit brakes the hanger plate 230, so that the hanger plate 230 cannot rotate.
