[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes an assembled beam structure of a photovoltaic bracket, including at least two main beams 1, with multiple boards 2 laid on the upper ends of the main beams 1. The main beams 1 are arranged horizontally, and the boards 2 are arranged longitudinally. A fastening device for fixing the boards 2 is provided on the upper ends of the main beams 1; the boards 2 are fixed to the upper ends of the main beams 1 by the fastening device, and the main beams 1 cooperate with the boards 2 to form a supporting structure for the photovoltaic equipment.

[0025] The fastening device includes a U-shaped member 3 and a protrusion 4. The protrusion 4 is fixedly connected to the upper end of the main beam 1. The upper end of the protrusion 4 is provided with a positioning groove 9 for placing the sandalwood board 2. The U-shaped member 3 is sleeved on the outer side of the sandalwood board 2, and the lower end of the U-shaped member 3 is snapped into the positioning groove 9.

[0026] A cross fixing structure is provided at the connection between the U-shaped member 3, the sandalwood board 2 and the main beam 1, and the cross fixing structure is detachably connected to the main beam 1, the sandalwood board 2 and the U-shaped member 3.

[0027] The protrusion 4 at the top of the main beam 1 holds the board 2 in place from the bottom, while the U-shaped piece 3 on the outside of the board 2 holds the board 2 in place from the top and sides. The cross-shaped fixing structure connects the board 2, U-shaped piece 3, and main beam 1 into a single unit. This design offers the advantage of a more secure connection between the main beam 1, board 2, and U-shaped piece 3, preventing the entire connection from becoming loose due to a single bolt falling off.

[0028] About the cross fixed structure:

[0029] The cross fixing structure includes:

[0030] The first threaded rod 5 vertically passes through the U-shaped member 3, the sandalwood board 2 and the main beam 1. The first threaded rod 5 is slidably connected to the sandalwood board 2, the main beam 1 and the U-shaped member 3. The upper and lower ends of the first threaded rod 5 are sleeved with first fastening nuts 7. The first fastening nuts 7 are threadedly connected to the first threaded surface 11 provided on the outer side of the first threaded rod 5.

[0031] The second threaded rod 6 horizontally passes through the U-shaped part 3, the sandalwood board 2 and the first threaded rod 5. The second threaded rod 6 is slidingly connected to the U-shaped part 3, the sandalwood board 2 and the first threaded rod 5. The left and right ends of the second threaded rod 6 are sleeved with second fastening nuts 8. The second fastening nut 8 is threadedly connected to the second threaded surface 12 opened on the outside of the second threaded rod 6.

[0032] When fixing the U-shaped member 3 and the sandalwood board 2, first vertically insert the first threaded rod 5 into the through holes opened at the top of the U-shaped member 3, the top of the sandalwood board 2 and the top of the main beam 1, and then screw the first fastening nut 7 onto the exposed ends of the first threaded rod 5. The first fastening nut 7 is tightly pressed against the lower end surface of the main beam 1 and the upper end surface of the U-shaped member 3 to fix the sandalwood board 2 and the U-shaped member 3;

[0033] Then, insert the second threaded rod 6 horizontally into the through holes opened on the sides of the U-shaped part 3, the sandalwood board 2 and the first threaded rod 5, and tighten the second fastening nuts 8 to fix the two ends of the second threaded rod 6. The second fastening nuts 8 can perform secondary reinforcement of the sandalwood board 2 and the U-shaped part 3 from the sides of the sandalwood board 2 and the U-shaped part 3. The cross connection structure formed between the second threaded rod 6 and the first threaded rod 5 can improve the structural strength of the first threaded rod 5, and at the same time can also limit the rotation of the first threaded rod 5, thereby preventing the first threaded rod 5 from loosening due to rotation and the first fastening nut 7.

[0034] To prevent dust and liquid from adhering to the threads of the first and second threaded rods 5 and 6 and hindering the opening of the first and second fastening nuts 7 and 8, a protective cover 13 is provided at the upper end of the protrusion 4. A protective groove 16 is defined at the lower end of the protective cover 13 to accommodate the U-shaped member 3, the first and second fastening nuts 7 and 8. The protective cover 13 is detachably connected to the protrusion 4. The protective cover 13, located at the upper end of the protrusion 4, fits over the outer surface of the U-shaped member 3, protecting the U-shaped member 3, the exposed first and second threaded rods 5 and 6, and the first and second fastening nuts 7 and 8. This improves the service life of the cross-fixing structure.

[0035] In a preferred embodiment, the lower end of the protective cover 13 is provided with multiple rubber ball plugs 15. Each rubber ball plug 15 is fixedly connected to each corner of the lower end surface of the protective cover 13. The rubber ball plugs 15 snap-fit ​​into the slots 14 provided at the upper end of the protrusion 4. After the cross-fixing structure is completed to secure the main beam 1, the slats 2, and the U-shaped member 3, the protective cover 13 is placed over the outer side of the U-shaped member 3. The rubber ball plugs 15 at the lower end of the protective cover 13 are aligned with the slots 14 provided at the upper end of the protrusion 4 and pushed into the slots. The rubber ball plugs 15 elastically contract and snap into the corresponding slots 14, completing the assembly of the protective cover 13. This snap-fit ​​installation method makes the protective cover 13 easy to disassemble, install, and replace, facilitating maintenance of the slat structure.

[0036] Of course, in addition to the snap-fit ​​fixing method, other methods such as bolt connection can also be used to fix the protective cover 13 to the protruding portion 4, which will not be explained in detail here.

[0037] In a preferred embodiment, the cross-section of the steel plate 2 is I-shaped, and the inner sidewall of the U-shaped member 3 forms an I-shaped slot that fits within the steel plate 2. The steel plate 2 is an I-shaped steel structural member. Its cross-sectional shape provides excellent rigidity and stability, enabling it to withstand significant pressure and weight. Furthermore, the unique structure of the I-shaped steel structure ensures its strength while remaining relatively lightweight. This characteristic makes the I-beam easier to handle during construction, saving construction time and improving project duration.

[0038] The second threaded surface 12 is sleeved on the outer side of the sandalwood board 2, and the inner side wall of the second threaded surface 12 forms a mutually interlocking matching structure with the outer side wall of the sandalwood board 2, which is more stable after assembly.

[0039] In another preferred embodiment, the first threaded rod 5 and the second threaded rod 6 are each sheathed with a plurality of rubber washers, each of which is placed between the first fastening nut 7 and the main beam 1, the first fastening nut 7 and the U-shaped member 3, and the second fastening nut 8 and the sandalwood board 2. The rubber washers are used to distribute the stress at the connection between the first fastening nut 7 and the main beam 1, the first fastening nut 7 and the U-shaped member 3, and the second fastening nut 8 and the sandalwood board 2, thereby increasing the tightness of the first fastening nut 7 and the second fastening nut 8 to the mating parts and protecting the first fastening nut 7, the second fastening nut 8, the main beam 1, the sandalwood board 2, and the U-shaped member 3.

[0040] How this application works:

[0041] The slats 2 are fixed to the upper end of the main beam 1 by a fastening device, and the main beam 1 and the slats 2 form a supporting structure of the photovoltaic device.

[0042] The protrusion 4 at the top of the main beam 1 restrains the board 2 from its bottom, while the U-shaped piece 3 on the outside of the board 2 restrains the board 2 from its top and sides. The cross-shaped fixing structure connects the board 2, U-shaped piece 3, and main beam 1 into a single unit. The advantage of this design is that the connection between the main beam 1, board 2, and U-shaped piece 3 is more secure, and the problem of a single bolt falling off causing the entire connection to loosen and fall off cannot be caused by the detachment of a single bolt.
