[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a reinforced high-weather-resistant photovoltaic frame, including a frame profile 1, a partition board 2, a reinforcing plate 3, a coating 4, a connecting block 5, a limiting block 6, and a fixing bolt 7.

[0031] The cross-section of the frame profile 1 is in an I shape, and hollow rectangles are connected to the upper and lower surfaces of the I-shaped frame profile 1. The frame profile 1 is made of aluminum alloy material, and a reinforcing structure is arranged inside the frame profile 1. The reinforcing structure arranges the partition board 2 and the reinforcing plate 3 to increase the support strength of the device while reducing the weight of the device. The reinforcing structure includes a partition board 2, which is arranged in the rectangular hollow of the frame profile 1 and is fixedly connected to the inner wall of the rectangular hollow. Three partition boards 2 are arranged in parallel, and the three partition boards 2 divide the rectangular hollow into four chambers. The inner wall of the chamber of the frame profile 1 is fixedly installed with a reinforcing plate 3, and the reinforcing plate 3 is located in the middle two chambers. The two reinforcing plates 3 are symmetrically arranged obliquely to form a triangular structure. A coating 4 is arranged on the outer surface of the frame profile 1, and the coating 4 is an anti-corrosion paint;

[0032] As shown Figure 1 in the figure, a rectangular hollow is provided on the surface of the frame profile 1. Taking the rectangular hollow as a connecting member, the frame profile 1 presents an I-shaped structure. Photovoltaic panel components can be installed on both sides of the I-shaped frame profile 1 to reduce the area of the photovoltaic frame in the photovoltaic module. Since the frame profile 1 is made of aluminum alloy material and has a hollow surface, the device is relatively light in weight. At the same time, a partition 2 and a reinforcing plate 3 are arranged in the rectangular hollow of the frame profile 1. The reinforcing plate 3 is inclined to form a triangular structure, and the triangular structure is used to increase the support strength of the frame profile 1. The anti-corrosion coating 4 on the outer surface of the frame profile 1 can increase the weather resistance of the frame profile 1.

[0033] The connecting block 5 is composed of two cross-shaped structures arranged parallel up and down. The two cross-shaped structures of the connecting block 5 are fixedly connected by a connecting member. The two cross-shaped structures of the connecting block 5 are respectively aligned with the upper and lower chambers on the surface of the frame profile 1. Threaded connection holes are provided on the surface of the connecting block 5, and corresponding threaded connection holes are provided on the surface of the frame profile 1. A limiting block 6 is provided on the surface of the connecting block 5. The limiting block 6 is a square structure, and the cross-section of the limiting block 6 is larger than the cross-section of the chamber on the surface of the frame profile 1. The threaded connection holes on the surface of the connecting block 5 and the threaded connection holes on the surface of the frame profile 1 are connected by fixing bolts 7;

[0034] As shown Figures 1-6 in the figure, the connecting block 5 can be used to connect the frame profiles 1. One end of the cross-shaped connecting block 5 is inserted into the upper and lower chambers of the frame profile 1. When the limiting block 6 on the surface of the connecting block 5 contacts the surface of the frame profile 1, the connecting block 5 cannot be inserted further at this time, and the threaded connection holes on the surface of the connecting block 5 are aligned with the threaded connection holes on the surface of the frame profile 1. The connecting block 5 and the frame profile 1 can be connected by using the fixing bolts 7. The cross-shaped connecting block 5 can be used to connect multiple frame profiles 1 to one end of the connecting block 5 respectively, so as to form a cross-shaped photovoltaic panel structure centered on the connecting block 5.

[0035] Working principle: When using this reinforced highly weather-resistant photovoltaic frame, the hollow frame profile 1 can reduce the weight of the device, and a partition 2 and a reinforcing plate 3 are arranged in the rectangular hollow of the frame profile 1. While not increasing the weight of the device, the support strength of the frame profile 1 is ensured. An anti-corrosion coating 4 is provided on the surface of the frame profile 1 to increase the weather resistance of the device. One end of the connecting block 5 is inserted into the chamber of the frame profile 1. After the limiting block 6 contacts the surface of the frame profile 1, the threaded holes on the surface of the connecting block 5 and the frame profile 1 are aligned at this time. The frame profile 1 and the connecting block 5 can be connected by using the fixing bolts 7, which increases the overall practicality.
