DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention provides a photovoltaic assembly frame structure, including: a plurality of bracket parts 1, a plurality of fixing parts 2 and at least two supporting parts 3.

[0024] The ends of the multiple bracket parts 1 are connected in sequence to form a frame, and the photovoltaic module is set in the frame. The photovoltaic module is fixed in the frame through the frame formed by the multiple bracket parts 1, so as to protect the photovoltaic module, and the photovoltaic module can be suspended in the air through the frame. Of course, support columns are required to support the frame so that the photovoltaic module is suspended in the air. Optionally, the multiple bracket parts 1 can be made of carbon fiber material.

[0025] The multiple fixing parts 2 sequentially fix and connect the ends of two adjacent bracket parts 1, thereby improving the stability of the connection between the adjacent bracket parts 1, so that the photovoltaic module can be stably arranged in the frame structure.

[0026] The ends of at least two support parts 3 can be slidably arranged on two parallel bracket parts 1, and at least two support parts 3 are arranged at intervals, so that photovoltaic modules of different sizes can be installed, that is, the width between the two support plates 31 can be adjusted by two support plates 31, and photovoltaic modules of different widths can be installed. When the photovoltaic module is installed, the support part 3 is fixed to the bracket part 1, so that the displacement of the support part 3 can be avoided. The photovoltaic module is arranged on the support part 3, and the photovoltaic module is located in the frame surrounded by the bracket part 1, so that the photovoltaic module in the frame can be protected. Since the photovoltaic module can be installed with photovoltaic modules of different sizes through the support part 3, the frame formed by the multiple bracket parts 1 has a wider range of use.

[0027] In one embodiment, the plurality of bracket parts 1 each include a connector 11 and a fixing part 12, and the adjacent connectors 11 and the adjacent fixing parts 12 are fixedly connected by the fixing part 2, wherein the frame enclosed by the connectors 11 encloses the fixing parts 12, so that the fixing parts 12 are located on the inner side of the connectors 11, and the two ends of at least two support parts 3 can be slidably arranged on two parallel connectors 11, and when the photovoltaic module is installed, at least two support parts 3 are fixed on the fixing parts 12. Optionally, the plurality of bracket parts 1 is four, and the adjacent ends between the four bracket parts 1 are connected together by the fixing parts 2. The four bracket parts 1 each include a connector 11 and a fixing part 12. The adjacent connectors 11 can be fixed together by the plurality of fixing parts 2, and the adjacent fixing parts 12 are tightly fixed together without loosening or even falling off. The two support parts 3 can slide on the connector 11, so that the photovoltaic modules of different sizes can be adjusted in width through the two support plates 31. When the photovoltaic assembly is installed, at least two support parts 3 are fixed to the fixing member 12 , so as to avoid displacement of the support parts 3 .

[0028] In one embodiment, the ends of the connecting members 11 are provided with connecting grooves 111, and the plurality of fixing portions 2 fix the adjacent connecting members 11 through the connecting grooves 111. It should be noted that the connecting grooves 111 can provide a mounting channel for the connecting members 11, so that the fixing portions 2 can tightly fix the adjacent connecting members 11 together. Of course, while fixing the adjacent connecting members 11 together, the fixing portions 2 can also fix the adjacent fixing members 12 together.

[0029] like Figure 5 As shown, in one embodiment, the plurality of fixing parts 2 each include a fixing frame 21 and a fastening frame 22, the two ends of the fixing frame 21 are respectively extended into the adjacent connection grooves 111 to fix the adjacent connecting members 11, and the two ends of the fastening frame 22 are arranged on the outer wall of the adjacent connecting members 11 to fasten the adjacent connecting members 11. It should be noted that the fixing frame 21 can make the adjacent bracket parts 1 fixedly connected together, and the fastening frame 22 can make the adjacent bracket parts 1 fixedly connected more tightly. Of course, the fastening frame 22 can fasten the adjacent bracket parts 1 so that the bracket parts 1 cannot fall apart, thereby improving the stability of the bracket parts 1.

[0030] In one embodiment, the outer structures of the fixing frame 21 and the fastening frame 22 are both L-shaped or arc-shaped. Since the adjacent bracket parts 1 need to be in a mutually perpendicular state when splicing, the adjacent bracket parts 1 are conveniently connected together through the L-shaped fixing frame 21, and at the same time, the bracket parts 1 are conveniently fastened together more closely through the L-shaped fastening frame 22. Of course, in addition to the outer structures of the fixing frame 21 and the fastening frame 22 being both L-shaped or arc-shaped, they can also be other structures, which are no longer limited here. In addition, the fixing frame 21 and the fastening frame 22 are made of aluminum alloy. When subjected to external forces, the L-shaped structure has good strength and rigidity in combination with the aluminum alloy material, can withstand greater pressure and tension, can effectively disperse and resist impact, improve the structural stability of the entire frame, and can avoid the phenomenon of photovoltaic components falling and being damaged.

[0031] In one embodiment, the fastening frame 22 includes a bracket 24 and a fastening bolt 23, and both ends of the bracket 24 are arranged on the outer wall of the adjacent connecting member 11, and the fastening bolt 23 passes through the bracket 24 and can be screwed with the outer wall of the connecting member 11. The fastening bolt 23 passes through the bracket 24 and can be screwed with the outer wall of the connecting member 11, so that the adjacent bracket parts 1 can be fastened together. Of course, when disassembly is required, the fastening bolt 23 can also be loosened to separate the adjacent bracket parts 1. Of course, in addition to fastening the adjacent bracket parts 1 by the fastening bolt 23, the bracket 24 can also be directly welded to the outer wall of the adjacent connecting member 11.

[0032] See also Figure 3 and Figure 4As shown, in one embodiment, at least two support parts 3 each include a support plate 31, two connection blocks 32 and two sliders 33, the two ends of the support plate 31 are placed on two parallel bracket parts 1, the two connection blocks 32 are respectively vertically arranged on the two ends of the support plate 31, and the two sliders 33 are respectively vertically arranged on one end of the corresponding connection block 32 and slidably arranged on the outer wall preset slide rail 110 of the bracket part 1. Optionally, there are at least two support plates 31, and the two support plates 31 are respectively spaced and slidably arranged on the outer side wall of the connecting member 11. By placing photovoltaic modules of different sizes on the support plates 31, photovoltaic modules of different sizes can be fixed in the frame formed by the bracket part 1, which can improve the use range of the frame of the photovoltaic module. It should be noted that the two support plates 31 have the same structure. In addition, when installing the photovoltaic module, it is necessary to position the photovoltaic module first, and it is necessary to find a positioning hole 5 that can cooperate with the photovoltaic module. The positioning hole 5 is set on the fixing part 12 to ensure that the position of the photovoltaic module is not biased. After the photovoltaic module is positioned, it is necessary to adjust the distance between the two support plates 31 so that it can be adjusted to the maximum width of the photovoltaic module so that the photovoltaic module can be placed on the two support plates 31. At this time, the two support plates 31 are fixed to the fixing part 12 on the bracket part 1 to prevent the two support plates 31 from sliding.

[0033] In one embodiment, at least two support parts 3 further include two threaded shafts 34, two extrusion plates 36 and two rotating disks 35. The two threaded shafts 34 are respectively screwed and pass through the bracket part 1 to be connected with the corresponding rotating disks 35. The two rotating disks 35 are respectively connected with the corresponding extrusion plates 36. The two extrusion plates 36 are respectively extruded on two parallel bracket parts 1. It should be noted that by driving the threaded shafts 34, the rotating disk 35 is driven to rotate, and the extrusion plates 36 connected to the rotating disk 35 also rotate accordingly. The extrusion plates 36 at different positions of rotation squeeze different positions of the fixing member 12 on the bracket part 1, so that the extrusion plates 36 and the fixing member 12 are squeezed, that is, the extrusion plates 36 are pressed on the fixing member 12, so that the support plate 31 can avoid displacement.

[0034] like Figure 2 As shown, in one embodiment, it further includes a plurality of support rods 4, and the plurality of support rods 4 are respectively arranged on adjacent bracket parts 1. The support rods 4 can enhance the stability of the adjacent bracket parts 1, so that the adjacent bracket parts 1 are not easy to fall. Optionally, the plurality of support rods 4 is four, and the four support rods 4 are respectively arranged on adjacent bracket parts 1.

[0035] In one embodiment, one end of the support rod 4 is rotatably disposed on one of the bracket parts 1, and the other end is fixed on the adjacent bracket part 1. By rotating the support rod 4 to the adjacent bracket part 1 and fixing it on the bracket part 1, of course, the support rod 4 can be rotated by the rotating shaft. The fixing member 12 of the support rod 4 on the bracket part 1 can improve the stability of the adjacent bracket part 1.
