[0002] In recent years, new energy represented by wind power and photovoltaic power generation has achieved remarkable results, with a large installed capacity, a steadily increasing proportion of power generation, a rapid decline in costs, and has basically entered a new stage of development without subsidies at parity. At the same time, to promote the integrated development of new energy development and utilization and rural revitalization, local governments support farmers to build household photovoltaics on the roofs of their own buildings. However, the roof styles of rural self-built houses vary from place to place, and the lighting conditions are different in different places. Conventional fixed brackets can only be slightly adjusted locally and cannot be adjusted over a large area according to the slope of the house roof and the sunshine angle. Therefore, we propose a photovoltaic panel bracket with adjustable angle to solve the above problems. Content of the Utility Model

[0009] A further improvement of the angle-adjustable photovoltaic panel support of the utility model is that a bearing for inserting the shaft rod is installed in the positioning sleeve.

[0021] By starting the driving motor 9 to drive the output shaft 11 to rotate, the small sprocket 12 can be driven to rotate, and the large sprocket 8 can be driven to rotate through the transmission belt 13, thereby driving the photovoltaic panel frame 2 to adjust the angle, and further adjusting the angle of the photovoltaic panel assembly 3 installed on the photovoltaic panel frame 2, that is, the illumination angle can be adjusted in a large area and the inclination angle can be increased according to the angles of different building roof shapes in different places, increasing the illumination time of the photovoltaic panel in different quarters and stages, and improving the power generation efficiency.

[0022] Wherein, the chassis 1 is of an A-shaped structure, and a positioning sleeve 4 for the shaft rod 7 to be movably inserted and passed through is arranged at the top of the chassis 1;

[0023] The positioning sleeve 4 is detachably connected to the top of the chassis 1; in this embodiment, screw holes 5 are correspondingly provided on both the positioning sleeve 4 and the top of the chassis 1, and the positioning sleeve 4 and the chassis 1 are fixed by bolts passing through the screw holes 5 on the positioning sleeve 4 and inserting into the screw holes 5 on the chassis 1.

[0024] The rotatable connection between the photovoltaic panel frame 2 and the chassis 1 is realized through the cooperation of the arranged shaft rod 7 and the positioning sleeve 4, which is beneficial to stably adjust the angle; the chassis 1 with an A-shaped structure has the effect of stable force support.

[0025] Wherein, referring to Figures 1 - 2 as shown, a bearing 6 for the shaft rod 7 to be inserted is installed in the positioning sleeve 4.

[0026] By setting the positioning sleeve 4 to be detachable, it is convenient to disassemble, inspect and clean it from the chassis 1. After using for a period of time, it can be removed to detect, clean the ash and maintain the bearing 6 therein and other operations.

[0029] Among them, the driving motor 9 is a forward and reverse motor. In this embodiment, the driving motor 9 is fixed to the outside of the chassis 1 through a buckle 10.
