[0029] Embodiment 1
[0030] For the photovoltaic main beam 1 with a rhombic cross-section as Figure 2 described, since there are gaps on both sides in the vertical direction, using a traditional U-bolt structure is likely to cause deformation of the purlin or the photovoltaic main beam 1 during use, while using purlins with better special-shaped fitting effect has higher production processing and raw material costs.
[0031] As Figures 1 - 3 shown, a photovoltaic module connection device includes a photovoltaic main beam 1 with a rhombic cross-section, a purlin 2 with a common channel-shaped structure on the market, and a photovoltaic module 15. The purlin 2 is fixedly connected to the top of the photovoltaic main beam 1, the photovoltaic module 15 is fixedly connected to the purlin 2, the photovoltaic main beam 1 is fixedly connected to the purlin 2 through a connecting member, and a support member for limiting and supporting the photovoltaic main beam 1 is inserted through the connecting member. The surface of the support member in contact with the photovoltaic main beam 1 is set as an arc structure identical to the outer surface contour of the photovoltaic main beam 1. Through the cooperation of the support member and the connecting member, the purlin 2 is stably installed on the photovoltaic main beam 1 with a rhombic cross-section.
[0032] By using the support member and the connecting member in cooperation, a connection structure that can stably fit on the surface of the photovoltaic main beam 1 with a rhombic cross-section is formed. The support member is set separately, which can effectively fill the vacant parts on the left and right sides of the rhombic cross-section, and at the same time, the cost is lower.
[0033] In some alternative embodiments, the connecting member is composed of a first vertical rod 4, a second vertical rod 7, and a main beam clamp 6. The first vertical rod 4 and the second vertical rod 7 penetrate through the purlin 2 and the main beam clamp 6 and are fixedly arranged on the photovoltaic main beam 1.
[0034] Furthermore, the main beam fixture 6 is set as a U-shaped bending part, and the top surface of the main beam fixture 6 is designed as a flat structure, which can better fit the bottom of the diamond-section photovoltaic main beam 1. The support member is set as the first support block 5 arranged at the upper left of the photovoltaic main beam 1 and the second support block 10 arranged at the lower right of the photovoltaic main beam 1. The first vertical rod 4 and the second vertical rod 7 are both set as screw rods. The top of the first support block 5 and the bottom of the second support block 19 are both set as flat structures, so as to better contact the bottom of the purlin 2 and the top of the U-shaped bending part.
[0035] Preferably, the first vertical rod 4 penetrates through the purlin 2, the first support block 5, and the main beam fixture 6 from top to bottom and is locked by a nut. The second vertical rod 7 penetrates through the purlin 2, the second support block 10, and the main beam fixture 6 from top to bottom and is locked by a nut.
[0036] The nut is threadedly connected to the bottoms of the first vertical rod 4 and the second vertical rod 7 which are set as screw rods. An inner lining 3 can also be installed inside the purlin 2 for reinforcement support. The width of the inner lining 3 is set to be greater than the minimum distance between two parallel sides of the hexagonal surface of the screw head at the top of the screw rod and less than the maximum distance between any two points of the top screw head, so as to prevent the screw head at the top of the screw rod from slipping when installing the nut from the bottom, and the installation is more convenient.
[0037] Embodiment 2
[0038] As Figures 4 - 5 shown, the main beam fixture 6 is composed of a U-shaped block 8 and an arc-shaped block 9. The support member is set as the first support block 5 arranged at the upper left of the photovoltaic main beam 1 and the arc-shaped block 9 arranged at the lower right of the photovoltaic main beam 1. The first vertical rod 4 and the second vertical rod 7 are both set as screw rods.
[0039] Among them, the first vertical rod 4 penetrates through the purlin 2, the first support block 5, and the U-shaped block 8 on the main beam fixture 6 from top to bottom and is locked by a nut. The second vertical rod 7 penetrates through the purlin 2 and the arc-shaped block 9 on the main beam fixture 6 from top to bottom and is locked by a nut.
[0040] As an optional solution, an inner lining 3 is also arranged inside the purlin 2, and the inner lining 3 is used for reinforcement.
[0041] The difference from Embodiment 1 is that by designing the U-shaped block 8 and the arc-shaped block 9 as an integral structure, a slot is arranged at the bottom of the arc-shaped block 9, so that the length of the second vertical rod 7 can be set to be shorter than that of the first vertical rod 4, further saving the weight of the overall photovoltaic bracket.
[0042] Embodiment 3
[0043] As Figures 6 - 8As shown in the figure, the connecting member is set as the U-bolt 11, and the support member is set as the first support block 5 arranged on the upper left of the photovoltaic main beam 1. The U-bolt 11 passes through the first support block 5 and the purlin 2 and is locked by a nut.
[0044] As an alternative solution, the U-bolt 11 is composed of a vertical section 14, a horizontal section 16, and an arc section 13 that matches the outer surface contour of the photovoltaic main beam 1 with a diamond cross-section.
[0045] The vertical section 14, the horizontal section 16, and the arc section 13 form a structure that is the same as the outer contour of the photovoltaic main beam 1 with a diamond cross-section, so that it can better fit the photovoltaic main beam 1. Cooperating with the first support block 5 installed on the upper left of the photovoltaic main beam 1, the purlin in the shape of a several-character can be effectively and stably installed on the photovoltaic main beam 1.
[0046] In addition, as Figure 8 shown, as an alternative solution, a reinforcing portion 17 protruding outward is provided at the middle position of the purlin 2 for strengthening the structural strength of the existing purlin in the shape of a several-character.
[0047] The above is the preferred embodiment of the present invention. The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
