[0028] The following further describes the implementation mode of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] As shown in Figure 1 to Figure 7 shown:

[0030] Embodiment 1: The present invention provides a photovoltaic structure for a green building, including a support frame 1 with a hollow interior. An installation frame 2 is arranged inside the support frame 1. The photovoltaic panel 3 is placed on the installation frame 2. Installation plates 4 are arranged on the front and rear end faces of the support frame 1. Enclosing rings 5 are arranged on the installation plates 4 at intervals. A rotating disc 6 is rotatably connected inside the enclosing ring 5. A support rod 7 extending out of the enclosing ring 5 is arranged on the outer ring wall of the rotating disc 6;

[0031] It further includes a rotating clamping ball 8. The rotating clamping ball 8 is fixedly connected to the bottom of the support rod 7. An enclosing ball 9 is movably connected to the rotating clamping ball 8. A support foot plate 10 is arranged on the outer wall of the enclosing ball 9. A quick installation combination component is arranged between the photovoltaic panel 3 and the installation frame 2.

[0032] It should be noted that through the provided support frame 1, the installation frame 2 is arranged inside the support frame 1, the photovoltaic panel 3 is installed inside the installation frame 2, mounting plates 4 are arranged at the front end and the rear end of the support frame 1, the surrounding ring 5 is rotatably connected to the mounting plate 4, the rotating disk 6 is rotatably connected inside the surrounding ring 5, the support rod 7 is connected to the outer wall of the rotating disk 6, and the rotating ball 8 at the other end of the support rod 7 is also movably installed inside the surrounding ball 9. The bottom of the surrounding ball 9 is connected to the support foot plate 10. Thus, when it is necessary to install the photovoltaic panel 3, the inclination angle can be adjusted from 0° to 90° by rotating the support rod 7. At the same time, the support foot plate 10 and the support rod 7 are designed to be rotatable, so as to adapt to different building curved surfaces. On the one hand, it reduces the difficulty of installing the photovoltaic structure, and on the other hand, it improves the flexibility of installing the photovoltaic structure.

[0033] In this embodiment, the cross-sectional profile of the support frame 1 is a rectangle with a hollow interior. The installation frame 2 is welded to the inner walls around the support frame 1. The interior of the installation frame 2 is provided with spaced-apart hollow chambers 11, and the photovoltaic panel 3 is installed on each hollow chamber 11.

[0034] It should be noted that the support frame 1 is made of steel material, thus ensuring the firmness of the overall photovoltaic structure. Spaced-apart hollow chambers 11 are formed inside the installation frame 2, and the photovoltaic panel 3 is installed inside the hollow chambers 11. There is a gap between two adjacent photovoltaic panels 3. On the one hand, after the photovoltaic panel 3 generates heat, the dissipated heat can flow out better through the heat dissipation channel 18. Moreover, after the photovoltaic panel 3 is damaged, the gap makes it easier to replace it.

[0035] In this embodiment, the mounting plate 4 is fixed to the support frame 1. The mounting plate 4 is provided with a positioning shaft 12. Each surrounding ring 5 is fixedly connected to the positioning shaft 12. The rotating disk 6 is located inside the surrounding ring 5 and is penetrated by the positioning shaft 12. A notch 13 is provided on the outer ring wall of each surrounding ring 5. The support rod 7 extends out of the notch 13. The support rod 7 at the front end of the support frame 1 rotates along the long side direction of the support frame 1 within the notch 13, and the support rod 7 at the rear end of the support frame 1 rotates along the short side direction of the support frame 1 within the notch 13.

[0036] It should be noted that through the provided positioning shaft 12, the surrounding ring 5 is fixedly connected to the positioning shaft 12, and the rotating disk 6 is movably connected to the positioning shaft 12, so that the rotating disk 6 can rotate inside the surrounding ring 5. By providing the notch 13 on the surrounding ring 5, the support rod 7 can rotate within the notch 13. Thus, when installing the photovoltaic panel 3, the angle of the support rod 7 can be adjusted to adapt to different installation surfaces;

[0037] Meanwhile, rotate the support rod 7 at the front end of the support frame 1 along the long side direction of the support frame 1 within the notch 13, and rotate the support rod 7 at the rear end of the support frame 1 along the short side direction of the support frame 1 within the notch 13. On the one hand, not only can the angle of each support rod 7 be adjusted, but also the rotation directions of the support rods 7 at the front and rear ends are perpendicular, which improves the installation flexibility and can also support the support frame 1 from different directions, ensuring the stability of the overall installation of the photovoltaic panel 3.

[0038] In this embodiment, annularly distributed threaded holes 14 are provided on the side of the rotating disk 6 away from the support frame 1, and positioning screws 15 are symmetrically provided on the outer wall of the surrounding ring 5. The positioning screws 15 pass through the surrounding ring 5 and cooperate with the threaded holes 14. The support rod 7 includes a first branch rod 7-1 and a second branch rod 7-2. The first branch rod 7-1 is fixedly connected to the outer ring wall of the rotating disk 6, and one end of the first branch rod 7-1 away from the rotating disk 6 has a threaded portion 16, and the threaded portion 16 is threadedly connected to the second branch rod 7-2.

[0039] It should be noted that by providing the annular threaded holes 14 on the rotating disk 6 and the positioning screws 15 on the surrounding ring 5, when the angle of the support rod 7 needs to be adjusted, rotate the rotating disk 6 to adjust the support rod 7 to an appropriate angle, and the rotating disk 6 can be fixedly connected to the surrounding ring 5 by locking the positioning screws 15 through the surrounding ring 5 into the threaded holes 14, thereby fixing the support rod 7. The fixing method is simple and convenient;

[0040] The support rod 7 is designed to be split, into a first branch rod 7-1 and a second branch rod 7-2. A threaded portion 16 is provided on the first branch rod 7-1. The threaded portion 16 is an external thread that cooperates with the internal thread inside the second branch rod 7-2. Rotating the second branch rod 7-2 can make it rotate on the threaded portion 16, thereby adjusting the overall length of the support rod 7, which can be adjusted according to the height of the installation surface, so that the support foot plate 10 can better fit the building installation surface and improve the installation flexibility.

[0041] In this embodiment, the rotating ball 8 is fixed at the bottom of the second branch rod 7-2. A spherical surrounding groove 17 is provided inside the surrounding ball 9. The rotating ball 8 is freely rotatable within the surrounding groove 17, and the surface area of the surrounding groove 17 is greater than half of the outer spherical area of the rotating ball 8.

[0042] It should be noted that by providing the surrounding groove 17 inside the surrounding ball 9, the rotating ball 8 can be embedded into the surrounding groove 17 and rotate within the surrounding groove 17, thereby adjusting the fitting angle of the support foot plate 10. In the present invention, the support foot plate 10 is used to fit the building installation surface, or a steel plate can be used to fit the installation surface and then bolts are installed between the steel plate and the installation surface for fixation. It is not limited to the above installation methods, as long as it does not slide after installation.

[0043] The internal area surrounding the groove 17 is designed to be larger than half of the outside of the rotating ball 8, so that when the rotating ball 8 rotates on the surrounding ball 9, the rotating ball 8 will not rotate out of the surrounding ball 9.

[0044] In this embodiment, a heat dissipation channel 18 is formed between two adjacent hollowed-out chambers 11. A rubber layer 19 is provided at the top of the mounting frame 2. The cross-section of the rubber layer 19 is a rectangle with a hollow interior. The bottom of the photovoltaic panel 3 is in contact with the rubber layer 19. A heat conduction layer 20 is provided at the bottom of the photovoltaic panel 3, and a phase change material layer 21 is provided at the bottom of the heat conduction layer 20.

[0045] It should be noted that by providing the heat dissipation channel 18 between two adjacent hollowed-out chambers 11, when the temperature of the photovoltaic panel 3 rises during operation, the heat dissipated from the bottom can be lost through the heat dissipation channel 18, avoiding the situation of overheating of the photovoltaic panel 3.

[0046] The rubber layer 19 is provided at the top of the mounting frame 2, and the photovoltaic panel 3 is mounted on the top of the rubber layer 19, which can reduce the direct contact between the photovoltaic panel 3 and the mounting frame 2. Since the mounting frame 2 is made of metal, it can reduce the situation of bump damage during the installation of the photovoltaic panel 3. At the same time, the heat conduction layer 20 is provided at the bottom of the photovoltaic panel 3. The heat conduction layer 20 is a graphene heat conduction film with a thickness of 0.5 mm. When heat is generated during the operation of the photovoltaic panel 3, the battery heat can be quickly conducted out. The phase change material layer 21 is provided at the bottom of the heat conduction layer 20. The phase change material layer 21 is made of paraffin-expanded graphite composite PCM with a thickness of 10 mm. After the heat conduction layer 20 conducts out the heat, it can better absorb / release latent heat and improve the heat dissipation effect during the operation of the photovoltaic panel 3.

[0047] In this embodiment, a bearing plate 22 is provided on one side of the support frame 1. On the side of the bearing plate 22 away from the support frame 1, a fan 23 is symmetrically provided. The fan 23 is externally powered. Below the support frame 1, air ducts 24 are symmetrically provided. Each air duct 24 is connected to the air outlet of the fan 23. A plurality of air supply ducts 25 are provided at intervals on each air duct 24. Each air supply duct 25 is located below the photovoltaic panel 3, and air outlets 26 are provided at intervals on the air supply duct 25.

[0048] It should be noted that by providing the fan 23, which is powered by direct current, the power supply of the fan 23 can be electrically connected to the photovoltaic panel 3. Thus, the electric energy converted by the photovoltaic panel 3 can supply power to the fan 23. The wind blown by the fan 23 can enter each air supply duct 25 through the air delivery duct 24. An installation ring is connected between the air delivery duct 24 and the bottom of the installation frame 2, so that the air delivery duct 24 can be installed below the installation frame 2. The air outlet 26 is installed on the air supply duct 25 and is located below the photovoltaic panel 3, so as to blow air below the photovoltaic panel 3. The heat generated during the operation of the photovoltaic panel 3 can be blown away and taken away through the heat dissipation channel 18, further improving the heat dissipation effect of the photovoltaic panel 3.

[0049] In this embodiment, the quick-installation combination component includes an installation card board 27, a clamping member 28, a suction cup one 29, and a suction cup two 30. The installation card board 27 is fixedly connected in each hollow cavity 11 and above the air outlet 26. Insertion holes 31 are symmetrically provided on the installation card board 27, and the suction cup one 29 is fixedly connected to the top of the installation card board 27.

[0050] In this embodiment, the clamping member 28 is symmetrically and fixedly connected to the bottom of the photovoltaic panel 3. The clamping member 28 is made of plastic material and can pass through the insertion holes 31 for mutual clamping. The suction cup two 30 is fixedly connected to the bottom of the photovoltaic panel 3, and the suction cup one 29 and the suction cup two 30 are magnetically attracted to each other.

[0051] It should be noted that by providing the quick-installation combination component, the clamping member 28 is made of plastic and is similar to the structure of a buckle, and both ends can be bent. When installing the photovoltaic panel 3, move the two legs of the clamping member 28 towards the middle. After passing through the insertion holes 31 on the installation card board 27, release the legs, and the clamping member 28 can be fixed in the clamping hole. At the same time, the suction cup one 29 and the suction cup two 30 are attracted to each other by magnetic force, improving the stability of the photovoltaic panel 3 after installation. Thus, in case of damage to the photovoltaic panel 3, it is not necessary to disassemble the whole, and the damaged photovoltaic panel 3 can be disassembled separately, reducing the maintenance cost.

[0052] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
