[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5As shown, a building facade photovoltaic module includes a frame 1 with four mounting slots 2 arranged in a rectangular array. A photovoltaic panel 3 is installed inside each of the four mounting slots 2, and the upper end of the photovoltaic panel 3 is rotatably connected to the frame 1. Several support cylinders 4 are provided on one side of the frame 1, and connecting grooves communicating with the support cylinders 4 are provided on the surface of the frame 1. Two support frames 5 are provided on the back side of the frame 1. A spring 6 is provided on the back side of the photovoltaic panel 3, with one end fixedly connected to the photovoltaic panel 3 and the other end fixedly connected to the support frame 5. A mounting bracket 7 is provided on the back side of the frame 1, below each photovoltaic panel 3, and a pulley 8 is provided on the mounting bracket 7. Suspension 9 is provided on both sides of the upper back side of frame 1. A rotating shaft 10 is provided on the suspension 9. A spool 11 is provided at both ends of the rotating shaft 10. An extension plate 12 is provided on the upper support frame 5 of the two support frames 5. A main shaft 13 is provided between the extension plate 12 and frame 1. A winding wheel 14 is provided on the main shaft 13. A motor 15 is provided on the back side of frame 1. The output end of the motor 15 and the main shaft 13 are both provided with meshing gears 16. A connecting rope 17 for connecting photovoltaic panel 3 and winding wheel 14 is also included. One end of the connecting rope 17 is fixedly connected to photovoltaic panel 3. The other end of the connecting rope 17 passes around pulley 8 and spool 11 and is fixedly connected to winding wheel 14.

[0019] When it is necessary to rotate the photovoltaic panel 3 to improve power generation efficiency, the motor 15 is started. Through the transmission between the gear 16 on the output end of the motor 15 and the gear 16 on the main shaft 13, the main shaft 13 and the winding wheel 14 on the main shaft 13 are driven to rotate. When the winding wheel 14 rotates, the connecting rope 17 wound on the outer surface of the winding wheel 14 is released. At this time, the compressed spring 6 will extend and the length of the spring 6 will gradually increase. As the length of the spring 6 increases, it will push the photovoltaic panel 3 to rotate outward of the frame 1, thereby completing the adjustment of the angle of the photovoltaic panel 3 to improve power generation efficiency. The maximum angle at which the photovoltaic panel 3 rotates outward of the frame 1 is 30°. The factor limiting the maximum angle of rotation of the photovoltaic panel 3 is the length of the connecting rope 17. At this time, the spring 6 is not fully extended to ensure that the photovoltaic panel 3 can be relatively stably maintained in the adjusted position after the rotation is completed, so as to resist sudden strong winds and other weather conditions.

[0020] There is a certain gap between the photovoltaic panels 3 to ensure that after the photovoltaic panels 3 are flipped to the outside of the frame 1 at the maximum angle, there will be no shading between the different photovoltaic panels 3.

[0021] When hail occurs, since hail does not hit the ground vertically, but tilts to a certain extent due to the wind, there is a high probability that the photovoltaic panel 3 will be hit by hail when it is vertical or rotated to the outside of the frame 1 at a certain angle. At this time, the motor 15 can be started to drive the winding wheel 14 to rotate. The winding wheel 14 winds up the connecting rope 17, so that the photovoltaic panel 3 can be rotated to the inside of the frame 1. The angle at which the photovoltaic panel 3 is rotated to the inside of the frame 1 is 15°, which can effectively prevent hail from hitting the photovoltaic panel 3 directly.

[0022] Furthermore, when the outer surface of the photovoltaic panel 3 is subjected to an accidental impact, such as by a person, the connecting rope 17 restricts the photovoltaic panel 3 from flipping outwards towards the frame 1, but does not restrict it from flipping inwards towards the frame 1. Therefore, when the photovoltaic panel 3 is impacted, it will flip inwards towards the frame 1, further compressing the spring 6 to cushion the impact force. At the same time, the connecting rope 17 also has a certain degree of elasticity. When the photovoltaic panel 3 flips inwards towards the frame 1, the connecting rope 17 itself will contract to a certain extent, so that the connecting rope 17 can stably pass around the pulley 8 and the spool 11 and wind around the take-up reel 14, avoiding large positional changes of the connecting rope 17 on the pulley 8, spool 11, and take-up reel 14, thus ensuring the normal use of the connecting rope 17.

[0023] The photovoltaic module is also equipped with components required for a solar power generation system, such as an inverter, a charge controller, a battery, a combiner box, and cables.

[0024] The frame 1 and support cylinder 4 can be fixed to the building facade 20 by bolts.

[0025] Appropriate gaps are reserved between the four sides of the photovoltaic panel 3 and the mounting groove 2 so that the photovoltaic panel 3 can be rotated normally in the mounting groove 2 without reducing the area of ​​the photovoltaic panel 3 too much.

[0026] Furthermore, the spring 6 is arc-shaped when fully extended, and the spring 6 located between the photovoltaic panel 3 and the support frame 5 is always in a compressed state, which facilitates better control of the flipping of the photovoltaic panel 3 through the spring 6 and makes the compression of the spring 6 smoother.

[0027] Furthermore, a foldable sleeve 18 is fitted on the outer surface of the spring 6. The sleeve 18 is made of rubber, and its two ends are fixedly connected to the photovoltaic panel 3 and the support frame 5, respectively, to reduce the contact between rainwater and the spring 6, reduce the corrosion of the spring 6, and improve its service life.

[0028] Furthermore, each photovoltaic panel 3 is provided with two springs 6 on its back side, and the two springs 6 are symmetrically arranged on both sides of the mounting frame 7 to improve the stability of the photovoltaic panel 3 when it is flipped.

[0029] Furthermore, a partition 19 is provided on the frame 1. The partition 19 is used to shield the top and sides of the frame 1 to prevent impurities from entering the frame 1 from the top and sides. At the same time, when hail or other impurities enter the frame 1 through the lower end of the inclined photovoltaic panel 3, since the partition 19 does not shield the bottom of the frame 1, the hail or other impurities can fall out of the frame 1 normally, preventing impurities from accumulating in the frame 1.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
