[0025] To better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0026] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0027] Figures 1 to 4 A solar panel connection structure according to an embodiment of the present utility model includes:

[0028] Conversion frame 1: It is composed of a conversion board 12, connecting ear plates 11 formed on the bottom surface of the conversion board 12, and a set of fixed convex columns 2 formed upward on the top surface of the conversion board 12; the conversion frame 1 is the main component of the device for bearing the load: the connecting ear plates 11 are connected to an external fixed structure such as a column, etc., and there are arc-shaped holes on the connecting ear plates 11, enabling the adjustment of the pitching angle of this structure;

[0029] The three-dimensional structure formed by the combination of the conversion board 12 and the set of fixed convex columns 2 functions to bear and transmit the load to the connecting ear plates 11. The conversion board 12 and the fixed ear plates can be integrally formed by casting, reducing the residual stress generated during the forming process of the internal complex structure. To bear the loads in all directions, the thickness of the conversion board 12 should be large; it can also be assembled by welding. The conversion board 12 can be circular, or an equilateral polygon, or other shapes that can adapt to the overall shape after the splicing of special-shaped photovoltaic modules.

[0030] Set of fixed convex columns 2: It includes several internal structural columns 21, connecting convex columns 22, and several external fixed columns 23. Among them: Internal structural columns 21: They are distributed at the eight intersection points of an equilateral octagon; the internal structural columns 21 and the external connecting columns form a spatial geometric structure, enabling the device to have strength in all directions. When the photovoltaic module is in use, it is subjected to various loads in different directions such as wind load, self-weight load, and temperature load. Using a hollow spatial structure can, while meeting the above working conditions, also have the effects of high structural strength and good heat dissipation.

[0031] Specifically, internal stiffening ribs 211 are provided between adjacent internal structural columns 21. Among them, two internal stiffening ribs 211 on the opposite sides of the octagon form an internal notch 2111. The overall size of this structure is large, and equipment tools need to be inserted into it during installation. Therefore, while further enhancing the overall strength of the structure, the internal stiffening ribs 211 can also be provided with some internal notches 2111 for maintenance to facilitate subsequent operations.

[0032] Connecting convex columns 22: There are four, located at the midpoints of the lines connecting two adjacent internal structural columns 21, and any two connecting convex columns 22 are not adjacent; the preferred way of the connecting convex columns 22 is to connect the positioning plate 4 and the conversion frame 1 in a quadrilateral manner, which is convenient for assembly.

[0033] The connecting convex columns 22 are structures used to fix the positioning plate 4 and the conversion frame 1. The positioning plate 4 is provided with raised screws and is installed in the screw holes on the end faces of the connecting convex columns 22. It can also be that the connecting convex columns 22 protrude for a certain length and are fixed to the positioning plate 4 by screws or other means after contact.

[0034] External fixing columns 23: are provided on the extension lines of the connections between the midpoint of the equilateral octagon and the internal structural columns 21; as described above, the internal structural columns 21 and the external fixing columns 23 form a space structure; the internal connecting columns and the external fixing columns 23 are respectively connected to the photovoltaic module installation rails 41, and through the photovoltaic module installation rails 41, the internal connecting columns and the external fixing columns 23 are further integrated in the space structure.

[0035] In some embodiments, a cover plate 3 is detachably provided between adjacent external fixing columns 23. Specifically, the external fixing columns 23 extend outward to both sides to further form fixing sides, and the sides are connected to the cover plate 3 by screws or other means. The cover plate 3 can achieve the effect of dust prevention. In addition, as described above, the working environment of this device is in a condition of drastic temperature changes. Using the split cover plate 3 can reduce the influence of temperature stress on the entire structure through gap adjustment compared with the overall structure.

[0036] Specifically, a U-shaped connecting rib 231 is provided between the internal structural columns 21 and the external fixing columns 23. As described above, compared with a whole piece of connecting rib, it can reduce temperature stress and also facilitate equipment to pass through the internal structure for maintenance.

[0037] Positioning plate 4: is provided with photovoltaic module installation rails 41. The internal structural columns 21 and the external fixing columns 23 are fixed to the installation rails, and the connecting convex columns 22 are fixed to the positioning plate 4.

[0038] Specifically, the photovoltaic module installation rails 41 are convex-shaped, and multiple groups of screws are provided in each direction of the photovoltaic module, which is convenient for installing the photovoltaic module.

[0039] In some embodiments, a plurality of positioning posts 411 are formed on one side of the photovoltaic module installation rail 41 that contacts the conversion frame 1, and positioning holes are correspondingly formed on the end faces of the inner structural posts 21 and the outer fixing posts 23.

[0040] The force transmission direction of the overall structure of this device is as follows: The photovoltaic module is arranged in the photovoltaic module installation rail 41. The photovoltaic module installation rail 41 and the fixed convex post group 2 are firmly fixed by means such as screws to achieve force transmission. The fixed convex post group 2 further transmits the force to the connecting ear plate 11 through the conversion plate 12, and then to the external structure. The positioning disc 4 can strengthen the integrity of the photovoltaic module installation rails 41 with each other, or can merely be used as a decorative part to block the function of the photovoltaic module installation rails 41.
