[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] Example 1

[0037] Please refer to the instruction manual appendix. Figure 1-7 A flexible photovoltaic module with cooling protection function includes a flexible photovoltaic panel 2, and further includes:

[0038] The automatic unfolding installation component 1 causes the flexible photovoltaic panel 2 to bend when the temperature exceeds the set value and unfolds into a horizontal shape when the temperature is lower than the set value.

[0039] The automatic deployment mounting component 1 includes an automatic adjustment component, a buffer component, and a mounting component; both the automatic adjustment component and the flexible photovoltaic panel 2 are mounted on the mounting component, and the automatic adjustment component is located between the flexible photovoltaic panel 2 and the rear wall of the automatic deployment mounting component 1; one end of the automatic adjustment component is connected to the buffer component, and the other end of the buffer component is connected to one end of the flexible photovoltaic panel 2.

[0040] The mounting box 11 is equipped with a cooling component 3 for air cooling of the flexible photovoltaic panel 2;

[0041] When the temperature rises, the automatic adjustment component drives the buffer component to move. After the buffer component moves a distance, when the temperature of the flexible photovoltaic panel 2 exceeds approximately 60°C, it will continue to drive one end of the flexible photovoltaic panel 2 to move relative to the automatic unfolding installation component 1, thus achieving a certain temperature buffering effect. At the same time, when one end of the flexible photovoltaic panel 2 moves, the flexible photovoltaic panel 2 will bend, thereby achieving the bulging of the flexible photovoltaic panel 2, which can improve the ventilation effect of the flexible photovoltaic panel 2. The cooling component 3 cools down the panel, thereby improving the heat dissipation effect.

[0042] This invention has a cooling protection function, which can cause the flexible photovoltaic panel 2 to bend when the temperature is too high, and effectively cool the flexible photovoltaic panel 2 through air cooling, thereby reducing safety hazards and avoiding accidents such as fires, and further improving safety performance.

[0043] Example 2

[0044] Based on Example 1, please refer to the appendix of the instruction manual. Figure 1-7 The automatic adjustment component includes a slide plate 17, a piston plate 18, and a mercury tank 19. The mercury tank 19 is fixedly installed on the inner wall of the automatic unfolding mounting component 1. The mercury tank 19 contains mercury. The piston plate 18 is slidably connected to the inside of the mercury tank 19. One end of the piston plate 18 is fixedly connected to one end of the slide plate 17. The slide plate 17 passes through the mercury tank 19 and is slidably connected to the mercury tank 19. The other end of the slide plate 17 is connected to the buffer component.

[0045] When the temperature rises, the mercury in the mercury tank 19 expands, pushing the piston plate 18 to slide along the inner wall of the mercury tank 19. The piston plate 18 drives the slide plate 17 to extend outward, and the slide plate 17 drives the buffer assembly to move.

[0046] The mounting assembly includes a mounting box 11, a groove 12, a lower connecting block 13, and an upper connecting block 14. The mounting box 11 has a groove 12 inside, where the automatic adjustment assembly and the flexible photovoltaic panel 2 are located. The lower connecting block 13 and the upper connecting block 14 are fixedly installed at the left and right ends of the flexible photovoltaic panel 2, respectively, and both the lower connecting block 13 and the upper connecting block 14 are located within the groove 12. The front and rear ends of the upper connecting block 14 are rotatably connected to the front and rear ends of the mounting box 11, respectively. The lower connecting block 13 is slidably connected to the mounting box 11 and is connected to the other end of the buffer assembly.

[0047] After the buffer component moves a distance, the lower connecting block 13 will continue to move when the temperature of the flexible photovoltaic panel 2 exceeds approximately 60°C. This causes one end of the flexible photovoltaic panel 2 to move relative to the automatic unfolding installation component 1, resulting in the flexible photovoltaic panel 2 bending.

[0048] The front and rear ends of the lower connecting block 13 and the upper connecting block 14 are respectively fixedly connected to the connecting shaft 112; the front and rear ends of the upper connecting block 14 are respectively rotatably connected to the front and rear ends of one side of the mounting box 11 through the connecting shaft 112.

[0049] On the inner walls of the front and rear ends of the mounting box 11, there are horizontal sliding grooves 110 respectively. Springs 111 are installed in the horizontal sliding grooves 110 respectively. The two sets of connecting shafts 112 of the lower connecting block 13 are slidably connected in the two sets of horizontal sliding grooves 110 respectively.

[0050] Preferably, one end of the spring 111 is in contact with the connecting shaft 112, and the connecting shaft 112 is located outside the spring 111;

[0051] The buffer assembly includes an L-shaped connecting plate 15 and an L-shaped pull plate 16; the other end of the sliding plate 17 is fixedly connected to one end of the L-shaped pull plate 16, the other end of the L-shaped pull plate 16 is slidably connected to one end of the L-shaped connecting plate 15, and the other end of the L-shaped connecting plate 15 is fixedly connected to the lower connecting block 13.

[0052] A square buffer gap is formed between the other end of the L-shaped pull plate 16 and one end of the L-shaped connecting plate 15;

[0053] During the heating process, the L-shaped pull plate 16 is moved by the slide plate 17. After the L-shaped pull plate 16 moves a distance, the temperature of the flexible photovoltaic panel 2 is about 60°C. The other end of the L-shaped pull plate 16 contacts one end of the L-shaped connecting plate 15. Subsequently, the L-shaped pull plate 16 moves the L-shaped connecting plate 15, and the L-shaped connecting plate 15 moves the lower connecting block 13. The connecting shafts 112 at the front and rear ends of the lower connecting block 13 slide along the transverse slide groove 110, which compresses the spring 111. The lower connecting block 13 causes the flexible photovoltaic panel 2 to bend.

[0054] During cooling, the L-shaped pull plate 16 is moved by the sliding plate 17. When the L-shaped pull plate 16 moves, a gap is formed between it and the L-shaped connecting plate 15. Under the elastic restoring force of the spring 111, the spring 111 drives the connecting shaft 112 of the lower connecting block 13 to move and reset, thereby realizing the automatic flattening of the flexible photovoltaic panel 2.

[0055] After the flexible photovoltaic panel 2 cools down to the set temperature, the present invention can also realize the automatic unfolding of the flexible photovoltaic panel 2 into a horizontal position to ensure the working effect.

[0056] Example 3

[0057] Based on Example 2, please refer to the appendix of the instruction manual. Figure 1-7 The cooling component 3 includes an air-cooling component and a push-button switch component, with the push-button switch component connected to the air-cooling component;

[0058] The air-cooled assembly includes a diffuser 31, a horizontal pipe 32, an air intake shroud 33, and a fan 34. The fan 34 is fixedly installed inside the air intake shroud 33. The air intake shroud 33 is fixedly connected to one end of the horizontal pipe 32, and the other end of the horizontal pipe 32 is fixedly connected to the diffuser 31. The diffuser shroud 31 is fixedly connected to the front end of the mounting box 11. Several sets of horizontal holes 35 are provided at both the front and rear ends of the mounting box 11. The horizontal holes 35 at the front end of the mounting box 11 are all connected to the diffuser shroud 31. The horizontal holes 35 are all connected to the groove 12, and the gap between the flexible photovoltaic panel 2 and the rear wall of the automatic unfolding mounting component 1 is connected to the horizontal holes 35.

[0059] The push-button switch assembly includes a push-pull trapezoidal block 36 and a push-button switch 37; the push-button switch 37 is fixedly connected to the outer wall of the mercury tank 19, and the push-pull trapezoidal block 36 is fixedly connected to the inner wall of the L-shaped pull plate 16, with the push-pull trapezoidal block 36 located in the middle of the L-shaped pull plate 16;

[0060] When the temperature of the flexible photovoltaic panel 2 is approximately 35°C, the trapezoidal block 36 is pressed and connected to the push switch 37. The push switch 37 is electrically connected to the fan 34, which powers on and starts the fan 34. Gas enters the diversion hood 31 through the horizontal pipe 32, and then is transported to the groove 12 through the horizontal hole 35 to cool the flexible photovoltaic panel 2. Afterward, the gas flows out through the horizontal hole 35 on the other side. When the temperature of the flexible photovoltaic panel 2 drops to the set value, the piston plate 18 drives the slide plate 17 and the L-shaped pull plate 16 to reset and move. When the trapezoidal block 36 is no longer in contact with the push switch 37, the fan 34 is de-energized and stops, thus realizing the automatic control of the opening and closing of the air cooling according to the set temperature.

[0061] Preferably, when the other end of the L-shaped pull plate 16 contacts one end of the L-shaped connecting plate 15, the pressing and pushing trapezoidal block 36 and the pressing switch 37 are always in contact.

[0062] This invention enables the L-shaped pull plate 16 to first drive the trapezoidal block 36 to contact the push switch 37 when the temperature reaches a certain value, energizing the fan 34 to cool the flexible photovoltaic panel 2. Then, as the temperature continues to rise to a certain value, the L-shaped pull plate 16 moves the L-shaped connecting plate 15 and the lower connecting block 13, allowing the flexible photovoltaic panel 2 to bend by nearly 30 degrees, improving the cooling effect. Simultaneously, when the temperature drops to a certain value, the flexible photovoltaic panel 2 automatically flattens out, and the fan 34 automatically stops.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
