[0031] See also Figures 1 to 4 As shown, this embodiment is a photovoltaic building roof, comprising:

[0032] The roof 11 and the photovoltaic panel 12 are fixed to the upper surface of the roof 11;

[0033] Shielding assembly; the shielding assembly includes a fixed plate 21, a sliding groove 22, a sliding plate 23, a limiting groove 231, a sliding column 24, a side connecting plate 25, a rotating plate 26 and a rotating shaft 261. The fixed plate 21 is fixed on both sides of the upper surface of the roof 11, and the fixed plate 21 is located on both sides of the photovoltaic panel 12. The sliding groove 22 is opened at the lower end of the inner side of the outer surface of the fixed plate 21. The sliding plate 23 is slidably installed inside the sliding groove 22. The limiting groove 231 is equidistantly opened on one side of the outer surface of the sliding plate 23. The sliding column 24 is slidably installed inside the limiting groove 231. The side connecting plate 25 rotates through the outer end of the sliding column 24. The rotating plate 26 is fixed on the lower side of the outer surface of the side connecting plate 25. The rotating shaft 261 is fixed and passes through the inside of the rotating plate 26, and both ends of the rotating shaft 261 rotate and pass through the fixed plate 21;

[0034] The sliding groove 22 is used to accommodate and guide the sliding movement of the sliding plate 23. The sliding plate 23 can move horizontally in the sliding groove 22 to drive the movement of the connecting rod 27 and the connecting frame 28. The sliding column 24 slides in the limit groove 22 as the sliding plate 23 moves, and is used to transmit power to the side connecting plate 25. The rotating plate 26 is connected to the fixed plate 21 through the rotating shaft 261, and can rotate under the action of the electric push rod 29 to achieve shielding or exposure of the photovoltaic panel 12.

[0035] The shielding assembly also includes a connecting rod 27, a connecting frame 28 and an electric push rod 29. The connecting rod 27 is fixed to the middle part of one side of the outer surface of the rotating plate 26. The connecting frame 28 is fixedly connected to one side of the outer surface of the connecting rod 27. The electric push rod 29 is fixed to the upper end of the connecting frame 28. The connecting frame 28 is L-shaped, and the electric push rod 29 is fixed to the upper surface of the fixed plate 21. The electric push rod 29, the connecting frame 28 and the connecting rod 27 are provided in two groups, which are respectively located at the upper ends of the two fixed plates 21.

[0036] The connecting rod 27 transmits the movement of the rotating plate 26 to the connecting frame 28. The electric push rod 29 is the power source of the entire shading system. It controls the movement of the connecting frame 28, the connecting rod 27 and the rotating plate 26 through telescopic action, thereby achieving the shielding or exposure of the photovoltaic panel 12. The connecting frame 28 is L-shaped and is used to connect the electric push rod 29 and transmit power.

[0037] Working principle:

[0038] In bad weather, the staff can use the external controller to control the electric push rod 29 to extend and retract. The extension of the electric push rod 29 will drive the connecting frame 28 to move outward, and drive the connecting rod 27 to move outward. The connecting rod 27 will simultaneously drive the sliding plate 23 to move to the same side, and the sliding plate 23 will simultaneously drive the sliding groove 231 to move outward. Under the fixation of the rotating shaft 261, the sliding column 24 will move to the same side and make the sliding column 24 parallel to the rotating shaft 261, and the rotating plate 26 will rotate clockwise until the rotating plate 26 is placed horizontally to cover the photovoltaic panel 12.

[0039] In this step, the photovoltaic panels 12 can be covered in time through the automatic shielding system, effectively preventing physical damage caused by weather conditions and ensuring equipment safety.

[0040] See also Figure 4 As shown; this embodiment is based on the above embodiment 1; and also includes:

[0041] The cleaning assembly includes a mounting groove 31, a fixing hole 32, a cleaning brush 33, a mounting hole 34, a spring 35 and a fixing post 36. The mounting groove 31 is provided on the lower surface of the rotating plate 26, and the fixing holes 32 are provided at the lower ends of both sides of the rotating plate 26. The cleaning brush 33 is installed inside the mounting groove 31, and the mounting holes 34 are provided on both sides of the cleaning brush 33. The spring 35 is fixed inside the mounting hole 34, and the fixing post 36 is fixedly connected to one end of the spring 35. The mounting hole 34 corresponds to the mounting groove 31 in a positive direction, and both ends of the fixing post 36 are immersed in the mounting groove 31. The lower end of the cleaning brush 33 contacts the photovoltaic panel 12;

[0042] The mounting groove 31 provides an installation position for the cleaning brush 33, ensuring that it is stably fixed on the rotating plate 26 so that it can synchronously drive the cleaning brush 33 to clean during rotation. The fixing hole 32 is used to further fix the cleaning brush 33 to ensure its stability and reliability during operation. The cleaning brush 33 is a component that performs cleaning work. As the rotating plate 26 rotates, the cleaning brush 33 will clean off the dust on the surface of the photovoltaic panel 12.

[0043] Working principle:

[0044] When the rotating plate 26 rotates, it will synchronously drive the cleaning brush 33 to rotate. The cleaning brush 33 will clean the dust on the surface of the photovoltaic panel 12 to reduce the dust. After the cleaning brush 33 ages, the staff will press the fixing column 36 inward to compress the spring 35 in the mounting hole 34. The fixing column 36 is immersed in the mounting hole 34, and the cleaning brush 33 can be removed and replaced.

[0045] This step can significantly improve the conversion efficiency of the photovoltaic panel 12 by regularly cleaning the dust and dirt on the surface of the photovoltaic panel 12. The cleaned photovoltaic panel 12 can absorb sunlight more fully and convert light energy into electrical energy, thereby improving the power generation efficiency of the entire solar power generation system.
