Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a high-load lightweight component for photovoltaic panels. Background Art

[0002] With the rapid development of photovoltaic technology, photovoltaic modules are gradually developing towards lighter weight and higher power. Especially with the application of ultra-thin photovoltaic glass, the development of lightweight modules has been rapid. However, the load capacity of lightweight modules using ultra-thin glass is generally not very high, and it is difficult to meet the module load requirements, especially for applications and installations in some high wind load and high snow load areas.

[0003] like Figure 1 As shown, currently, in order to meet the load requirements of lightweight modules, some photovoltaic module manufacturers usually increase the wall thickness of the frame and drill holes on the vertical and horizontal surfaces of the frame structure to install beams, and use self-tapping screws or rivets to fix the beams to the frame, thereby increasing the overall force of the module. However, the increased force of this structural method is concentrated on the horizontal surface of the frame, which can easily cause the frame to break and has poor bearing capacity. In addition, the existing beams are connected to the frame in a fixed manner, which makes installation, replacement and subsequent maintenance more difficult. Utility Model Content

[0031] Example 1

[0032] The embodiment of the utility model provides a high-load light-weight component for a photovoltaic panel, such as Figure 2-11As shown, it includes a frame and a plurality of cross beams 11, the frame includes a mounting frame 7, the mounting frame 7 includes two vertical sections 5 and two horizontal sections 6, one of the vertical sections 5 is provided with an L-shaped support arm 2 which is symmetrical up and down, the two L-shaped support arms 2 and one of the vertical sections 5 form a nut fixing groove 1, and the cross beam 11 is detachably connected to the nut fixing groove 1.

[0033] The working principle and beneficial effects of the above technical solution are as follows: an L-shaped support arm 2 that is symmetrical up and down is set on one of the vertical sections 5, thereby forming a nut fixing groove 1, and then the crossbeam 11 is detachably connected to the nut fixing groove 1; by setting the L-shaped support arm 2 that is symmetrical up and down, that is, connecting the crossbeam 11 through the L-shaped support arm 2, the force of the component is more concentrated on the vertical section 5 of the frame and the L-shaped support arm 2, the load borne by the component will be higher, the risk of frame breakage is effectively reduced, and the supporting performance of the component is improved, and the detachable connection between the crossbeam 11 and the nut fixing groove 1 is more conducive to the later installation and maintenance and replacement, and the practicality is higher.

[0034] Example 2

[0035] On the basis of Example 1, Figure 2-3 As shown, the mounting frame 7 and the upper L-shaped support arm 2 are provided with a mounting portion 3 .

[0036] The first forming method of the mounting portion 3 is as follows: a special-shaped matching section 4 is provided on the mounting frame 7 , and the special-shaped matching section 4 forms the mounting portion 3 with the upper horizontal section 6 and the upper L-shaped support arm 2 .

[0037] In this method, by providing a silicone layer 13 on the mounting portion 3 and limiting the photovoltaic panel 14 by the special-shaped matching segment 4, the connection between the photovoltaic panel 14 and the assembly can be made tighter;

[0038] The second forming method of the mounting portion 3 is as follows: an extension section 18 is provided on the mounting frame 7 , and the extension section 18 , the upper horizontal section 6 and the upper L-shaped support arm 2 form the mounting portion 3 .

[0039] Compared with the first method, this method reduces the special-shaped matching section 4, and does not use the special-shaped matching section 4 to limit the photovoltaic panel 14. Instead, the entire photovoltaic panel 14 is directly exposed to the sun (the photovoltaic panel is directly connected to the extension section 18 or the crossbeam 11), which can reduce the shading of the front of the photovoltaic panel 14 caused by the accumulation of rain or dust on the front of the photovoltaic panel 14, thereby increasing the power generation power of the photovoltaic panel 14;

[0044] like Figure 6 As shown, the middle portion of the crossbeam 11 may be provided with a hollow structure, so as to meet the needs of actual users for crossbeams of different widths and have a wider range of applications.

[0045] The working principle and beneficial effects of the above technical solution are as follows: first, align the crossbeam 11 and the frame at a 90-degree angle, then install the nut 9 to the appropriate position in the nut fixing groove 1 and the mounting groove 16 (the position is determined by a technician in this field or the installer), place the right-angle connector 10 at the contact position between the crossbeam 11 and the frame, and pass the two bolts 12 through the mounting holes 19 and cooperate with the nuts 9 respectively, thereby completing the connection between the crossbeam 11 and the frame, making the connection more stable, with stronger bearing capacity, and more convenient replacement and maintenance.

[0048] Preferably, hollow portions 15 are provided on both right-angled sides of the angle code 8 .

[0049] Preferably, a plurality of friction protrusions 20 are provided on the two right-angled sides of the angle code 8.
