Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frames, specifically to a high-strength photovoltaic frame and its photovoltaic module. Background Technology

[0002] Traditional photovoltaic (PV) frames are mostly made of aluminum alloy, steel, or composite materials with plastic as the base. They are primarily placed in barren areas or on residential rooftops, operating in harsh environments. A high rate of PV panel damage due to weather factors results in significant economic losses. Although manufacturers have made various attempts to enhance structural strength, current solutions have yielded unsatisfactory results. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a photovoltaic frame with a high-strength structure.

[0004] According to one aspect of the present invention, a photovoltaic frame with a high-strength structure is provided, comprising: a cavity having three cavity walls connected to each other: an upper wall, a right wall, and a lower left wall; a sloping tie wall passing through the intersection of the upper wall and the right wall and connected at both ends to a vertical rib rising from the upper wall and an extension of the lower right wall, which is an extension of the lower left wall; the sloping tie wall on one side of the intersection, together with the vertical rib and the upper wall, defines a triangular area I; and the sloping tie wall on the other side of the intersection, together with the right wall and the lower right wall, defines a triangular area II.

[0005] Preferably, the cavity further includes another cavity wall connected to the upper wall and the lower left wall, namely, the left wall.

[0006] Preferably, the vertical rib rises from the middle of the upper wall, and extends from the connection part of the vertical rib and the inclined wall on one side of the intersection point along a direction that is separated from and parallel to the upper wall to form an overflow groove base and an overflow groove connected to each other, forming a receiving groove with the vertical rib as the bottom of the groove and the upper wall, the overflow groove base and the overflow groove facing each other as the groove walls.

[0007] Preferably, a positioning rib is formed on at least one inner wall side of the cavity.

[0008] Preferably, a mounting protrusion of predetermined thickness is formed on the mounting wall that extends from the lower right wall relative to the inclined pull wall.

[0009] Preferably, the photovoltaic frame with high-strength structure has mounting holes in the mounting protrusions.

[0010] According to another aspect of the present invention, a photovoltaic module is provided, comprising two long and two short photovoltaic frame components of the high-strength structure described above, which are spliced ​​and fixed by corner brackets to form a rectangular structure.

[0011] The beneficial effects of this utility model are as follows: Based on the traditional photovoltaic frame, a sloping wall structure and two additional triangular structures are added, strengthening the overall structural strength. The mounting hole walls are thickened, optimizing the connection between the photovoltaic frame and the mounting bracket and avoiding the risk of tearing of the photovoltaic frame mounting holes. The receiving groove has been moved from the edge of the photovoltaic frame to the middle of the cavity, further strengthening the receiving groove in conjunction with the sloping wall, reducing the risk of photovoltaic panel bursting due to twisting and deformation of the receiving groove in the later stages of installation and use.

[0037] <Processing and Assembly Instructions>

[0038] Aluminum alloys are produced by hot extrusion forming to produce cross-sections that conform to... Figure 1 A high-strength photovoltaic frame.

[0039] After extrusion, the material is cut to a fixed length of 6050 (0, +20) mm and then aged at 185-195℃ for 3-4 hours. Following this, it undergoes sandblasting or shot blasting. Taking sandblasting as an example, the glass abrasive is 40-80 mesh, and the blasting speed is 25-35 Hz. Finally, it undergoes conventional anodizing.

[0040] Afterwards, further processing is carried out. The short ruler is cut into 1000 (0, +0.5) mm pieces, and the long ruler is cut into 2000 (0, +0.5) mm pieces. The mounting hole 17 is punched to be used for bolt connection with the base frame at the installation site later.

[0041] After being cut to a fixed length, the photovoltaic panels are inserted into the receiving groove 3 and sealed with sealant. The two long and two short photovoltaic frames are combined and fixed with corner brackets at the four corners to form a rectangular photovoltaic module.

[0043] On the mounting wall 7, which extends from the lower right wall 10 relative to the connection point with the inclined wall 6, a mounting protrusion 8 of predetermined thickness is formed, wherein a mounting hole 17 is provided.

[0044] The vertical rib 11 rises from the middle of the upper wall 12. The connection between the vertical rib 11 and the inclined wall 6 on the side of the intersection 20 extends in a direction that is spaced apart from and parallel to the upper wall 12 (preferably substantially parallel) to form an overflow groove base 1 and an overflow groove 2, forming a receiving groove 3 with the vertical rib 11 as the bottom and the upper wall 12, the overflow groove base 1, and the overflow groove 2 as the walls.
