Description

Technical Field

[0001] This invention relates to an aluminum photovoltaic frame, specifically a high-performance, impact-resistant aluminum photovoltaic frame. Background Technology

[0002] Photovoltaic modules generally consist of photovoltaic cells, ultra-clear glass, encapsulating film, encapsulation backsheet, and aluminum alloy frame. However, ultra-clear glass has its limitations; its high density results in a heavier photovoltaic module. For existing industrial and commercial rooftops, most have lower load-bearing capacity, posing a significant challenge to the application of single-glass photovoltaic modules. Furthermore, the large weight of each module also creates various inconveniences for construction workers.

[0003] For example, Chinese utility model patent CN216699923U discloses a frame assembly, including a third frame for assembly onto the third side of a photovoltaic panel and a fourth frame for assembly onto the fourth side opposite to the third side of the photovoltaic panel. One side of the third frame has a first connecting portion; one side of the fourth frame has a second connecting portion that can be matched and connected to the first connecting portion. At least one of the first and second connecting portions has a rough surface, which allows for stable assembly between the first connecting portion of the third frame and the second connecting portion of the fourth frame, resulting in good assembly performance between the third and fourth frames. During transportation and use after installation, if the photovoltaic panel is subjected to external impact, the glass and silicon wafers of the photovoltaic panel are easily damaged. The aforementioned frame assembly for the photovoltaic panel uses ordinary profiles and does not effectively buffer the impact on the photovoltaic panel, making it prone to damage during transportation and use.

[0004] In view of this, the present invention designs a high-performance, impact-resistant aluminum photovoltaic frame. Summary of the Invention

[0005] The main objective of this disclosure is to provide a high-performance, impact-resistant aluminum photovoltaic frame to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-performance, impact-resistant aluminum photovoltaic frame includes a primary photovoltaic frame, a folding frame, a connecting connector, and an aluminum photovoltaic frame. The primary photovoltaic frame has detachable and movable folding frames on both sides, and both folding frames are vertically oriented, i.e., the folding frames are set at approximately a 90-degree angle to the primary photovoltaic frame. The top of the two folding frames is interference-fitted to an aluminum photovoltaic frame, and the aluminum photovoltaic frame is used to install external photovoltaic modules. The distance between the aluminum photovoltaic frame and the primary photovoltaic frame is greater than 30 centimeters. The docking connector includes a moisture-proof docking rail and a channel steel bracket sleeve. The bottom of the first photovoltaic frame is fixedly connected to two parallel moisture-proof docking rails, and a channel steel bracket sleeve is fitted on the moisture-proof docking rail. The channel steel bracket sleeve has an I-shaped magnetic groove inside, that is, the end of the moisture-proof docking rail is magnetically attracted to the I-shaped magnetic groove. The moisture-proof docking rails on the two high-performance impact-resistant aluminum photovoltaic frames are spliced ​​together by the channel steel bracket sleeve. One side of the first photovoltaic frame is detachably and movably equipped with an impact-resistant baffle, and at least two L-shaped restraining clamps are fixedly connected to one side of the impact-resistant baffle. The clamping end of the L-shaped restraining clamp is hooked onto the frame of the folding frame. A C-shaped fastening ring is fixedly connected to the other side of the first photovoltaic frame. A first anti-corrosion rope is detachably connected to one of the folding frames, and the other end of the first anti-corrosion rope passes through the C-shaped fastening ring and is detachably connected to another folding frame.

[0007] Preferably, a first positioning seat and a second positioning seat are fixedly connected to both the left and right sides of the first photovoltaic frame, and the first positioning seat and the second positioning seat are distributed at the same height in the front and back positions. A rotating hole is opened on the side of the first positioning seat and the second positioning seat that are close to each other, and a horizontal disassembly shaft is inserted between the two rotating holes. The folding frame is fixedly installed on the surface of the horizontal disassembly shaft, and the end of the horizontal disassembly shaft rotates in the rotating hole.

[0008] Preferably, a concealed groove is provided on one side of the first photovoltaic frame, and an angle adjustment shaft is rotatably installed in the concealed groove. The impact-resistant baffle is detachably sleeved and installed on the surface of the angle adjustment shaft. A groove is provided on the top of the first photovoltaic frame, and a second photovoltaic panel is embedded and fixedly installed in the groove. The main material of the first photovoltaic frame is aluminum profile.

[0009] Preferably, the two folded frames are secured to the side near the impact-resistant baffle by a second anti-corrosion rope, i.e., the second anti-corrosion rope is taut.

[0010] Preferably, the folding frame is composed of a rectangular frame, horizontal and vertical crossbars, and vertical crossbars. The horizontal and vertical crossbars are fixedly connected to the inner wall of the rectangular frame, forming various rectangular spaces. That is, the horizontal and vertical crossbars are arranged in a crisscross pattern. A photovoltaic panel is installed in each rectangular space, and the L-shaped limiting clamp is hooked onto the rectangular frame.

[0011] Preferably, the top of the aluminum photovoltaic frame is provided with a photovoltaic mounting groove, and the aluminum photovoltaic frame is composed of an aluminum profile frame structure and a polyurethane composite material edge. The polyurethane composite material edge is wrapped around the outside of the aluminum profile frame structure, and the side of the aluminum photovoltaic frame is wider than the distance between the two moisture-proof docking rails.

[0012] Preferably, the top of the rectangular frame is flush with the top of the impact-resistant baffle, the bottom of the rectangular frame is always higher than the moisture-proof docking rail when it is set horizontally, and the distance between the two high-performance impact-resistant aluminum photovoltaic frames is less than the sum of the widths of the two aluminum photovoltaic frames.

[0013] Preferably, the moisture-proof connecting rail is made of I-beams, and the height of the I-beams is at least three centimeters, for installation and layout in complex terrain.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, when using an aluminum photovoltaic frame, the impact-resistant baffle is first swung to a vertical position to limit the position of the concealed groove. Then, the two folding frames are swung in opposite directions to a vertical position. The L-shaped limiting clips on the impact-resistant baffle are then fastened to the folding frames to fix the position of the impact-resistant baffle. The first anti-corrosion rope is then passed through the C-shaped tight ring and its two ends are tied to the folding frames to fix the two folding frames. This completes the aluminum photovoltaic frame. The aluminum photovoltaic frame is then attached to the two folding frames to enable the application of the entire photovoltaic system. With the tie-and-fix of the second anti-corrosion rope, the stress on the entire aluminum photovoltaic frame is more even, improving the overall stability.

[0015] (ii) In this application, the two moisture-proof docking rails on the first photovoltaic frame are set in parallel. The moisture-proof docking rails on the adjacent high-performance impact-resistant aluminum photovoltaic frames are docked to achieve the splicing of the high-performance impact-resistant aluminum photovoltaic frames. The end of the moisture-proof docking rail is inserted into the I-shaped magnetic groove in the channel steel bracket groove. It has a certain friction and magnetic attraction, and will not easily fall off. The layout is beautiful.

[0016] (iii) In this application, when not in use, the folding frame and the impact-resistant baffle are released from the fixation, and then the folding frame and the impact-resistant baffle are swung to a horizontal state, which can increase the laying area, so that more photovoltaic panels can be used, improve the utilization rate, and after being laid out, the space occupied is reduced, which facilitates transportation and has a better turnover rate.

[0017] (iv) In this application, the folding frame adopts a detachable installation method, which allows it to be quickly disassembled and transported. When disassembling, first make sure that the fixing of the folding frame is released, then move the folding frame towards the first positioning seat so that the horizontal disassembly shaft moves synchronously and disengages from the rotating hole on the second positioning seat. Then, the horizontal disassembly shaft can be pulled out from the rotating hole on the first positioning seat. The operation is very convenient, requires no more tools, and saves labor costs.

[0018] (v) In this application, the main material of the entire photovoltaic frame is aluminum profile, which has the superior performance of being lightweight and having strong impact resistance. Combined with the support of polyurethane composite material waving edge, its performance is further enhanced. Attached Figure Description
