[0002] Photovoltaic power generation is a clean energy that conforms to green development, an important development direction of energy transformation, and plays an important role in the energy revolution. The bifacial photovoltaic module in photovoltaic power generation is a very promising technology in the photovoltaic industry. In the construction of a photovoltaic system, the installation of photovoltaic modules is a crucial link. Photovoltaic modules, as the core components of solar power generation, usually consist of photovoltaic panels, frames, junction boxes, etc. The frame assembly, as an important load-bearing component of the photovoltaic panel, is particularly important for its structural strength in use.

[0003] However, in the actual installation process, especially when two adjacent photovoltaic module frames need to be connected and fixed through corner keys, the simple connection method may bring potential problems. This simple connection method may only rely on the physical insertion of the corner key or simple bolt fixation. Such a structure is prone to loosening during long-term use due to the influence of various environmental factors. Loosening will not only reduce the installation stability of the photovoltaic module, but may also affect the power generation efficiency and safety of the entire photovoltaic system, as well as the performance and service life of the photovoltaic panel. Summary of the Utility Model

[0004] Aiming at the above-mentioned disadvantages of the prior art, the utility model provides a single-glass photovoltaic module frame with high structural stability and high mechanical load strength, which can effectively solve the problems that the power generation efficiency of the photovoltaic system is affected and the service life of the photovoltaic panel is reduced due to the loosening of the corner key when two adjacent frames are connected by a simple corner key in the prior art.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0006] The utility model provides a single-glass photovoltaic module frame with high structural stability and high mechanical load strength, including two frames and two closed cavities respectively arranged in the two frames. A fixing plate is fixedly installed on the inner wall of the closed cavity. An installation groove is formed between the fixing plate and the inner wall of the closed cavity. A right-angled corner key is jointly arranged between two adjacent frames. A plurality of sliding grooves are formed on one side of the corner key close to the fixing plate. A sliding column is slidably connected inside the sliding groove. A clamping plate is fixedly installed at one end of the sliding column away from the corner key. A spring is sleeved outside the sliding column. One end of the spring is fixedly connected with the clamping plate, and the other end of the spring is fixedly connected with the outer side wall of the corner key.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model will be further described below with reference to the embodiments.

[0023] Embodiment: Refer to Figures 1 to 4, A single-glass photovoltaic module frame with high structural stability and high mechanical load strength, including two frames 1 and two closed cavities 2 respectively arranged in the two frames 1. A fixing plate 3 is fixedly installed on the inner wall of the closed cavity 2. An installation groove 31 is formed between the fixing plate 3 and the inner wall of the closed cavity 2. A right-angled corner key 4 is jointly arranged between two adjacent frames 1. A plurality of sliding grooves 5 are opened on one side of the corner key 4 close to the fixing plate 3. A sliding column 6 is slidably connected inside the sliding groove 5. One end of the sliding column 6 far from the corner key 4 is fixedly installed with a clamping plate 8. Each side of each clamping plate 8 is provided with an arc surface, and each arc surface is arranged opposite to the corresponding frame 1. A spring 7 is sleeved on the outer side of the sliding column 6. One end of the spring 7 is fixedly connected with the clamping plate 8, and the other end of the spring 7 is fixedly connected with the outer side wall of the corner key 4. A plurality of clamping holes 9 respectively adapted to the clamping plates 8 are opened on the fixing plate 3; when installing two adjacent frames 1 of the photovoltaic module, first clamp one of the frames 1 on the edge of the photovoltaic module. After adjusting its position, insert one end of the corner key 4 into the installation groove 31, and then also clamp the adjacent other frame 1 on the edge of the photovoltaic module and make the other end of the corner key 4 also snap into the corresponding installation groove 31. When the corner key 4 is inserted into the installation groove 31, the clamping plate 8 is squeezed so that the sliding column 6 slides in the reverse direction of the sliding groove 5, and at the same time the spring 7 is also compressed. After the corner key 4 is inserted into the installation groove 31, the clamping plate 8 also clamps in the corresponding clamping hole 9. Since the side of the clamping plate 8 close to the frame 1 is arc-shaped, the plurality of clamping plates 8 can continue to slide out from the clamping hole 9 close to the corner key 4 until it slides into the corresponding clamping hole 9, and the elastic force of the spring 7 makes the clamping plate 8 clamped in the corresponding clamping hole 9 and unable to slide out, thereby making the corner key 4 clamped with the frame 1. The connection between the corner key 4 and the two adjacent frames 1 is strengthened through the sliding column 6, the spring 7 and the clamping plate 8, the installation stability of the photovoltaic module is strengthened, preventing it from loosening and affecting the power generation efficiency and safety of the entire photovoltaic system, and extending the service life of the photovoltaic panel.

[0024] Further, the frame 1 is made of aluminum alloy material, and a corrosion-resistant metal coating is provided on the outer surface of the frame 1; the aluminum alloy material has the characteristics of light weight, firmness and good corrosion resistance. By further protecting it by setting a metal coating on the outside of the frame 1, its corrosion resistance in the environment is stronger, and its service life is extended.

[0025] Further, limiting rods 10 are symmetrically and fixedly installed at both ends of the sliding column 6. Limiting grooves 11 which are in limiting sliding connection with the limiting rods 10 are formed in the inner wall of the sliding groove 5. One side of the fixing plate 3 close to the corner key 4 is inclined. An anti-slip pad 12 is fixedly installed on the outer side of the corner key 4. The anti-slip pad 12 is made of silica gel. When the sliding column 6 slides in the sliding groove 5, the limiting rod 10 also slides in the corresponding limiting groove 11. The limiting rod 10 and the limiting groove 11 enhance the stability of the sliding column 6 during sliding, preventing the sliding column 6 from rotating and changing the direction of the clamping plate 8. The inclined setting of one side of the fixing plate 3 close to the corner key 4 facilitates the corresponding fixing plates 3 to fit when two adjacent frames 1 are fitted, thereby making their connection more stable. The silica gel anti-slip pad 12 increases the friction between the corner key 4 and the inner wall of the installation groove 31, thus further enhancing the connection stability between the corner key 4 and the frame 1.

[0026] The working principle of the present utility model is as follows:

[0027] When installing two adjacent frames 1 of the photovoltaic module, first, one of the frames 1 is clamped to the edge of the photovoltaic module. After adjusting its position, one end of the corner key 4 is inserted into the installation groove 31. Then, another adjacent frame 1 is also clamped to the edge of the photovoltaic module and the other end of the corner key 4 is also inserted into the corresponding installation groove 31. When the corner key 4 is inserted into the installation groove 31, the clamping plate 8 is squeezed, causing the sliding column 6 to slide in the reverse direction of the sliding groove 5. The limiting rod 10 also slides in the corresponding limiting groove 11. At the same time, the spring 7 is compressed. After the corner key 4 is inserted into the installation groove 31, the clamping plate 8 is also stuck in the corresponding clamping hole 9. Since one side of the clamping plate 8 close to the frame 1 is arc-shaped, a plurality of clamping plates 8 can continue to slide out from the clamping hole 9 close to the corner key 4 until they slide into the corresponding clamping hole 9. The elastic force of the spring 7 causes the clamping plate 8 to be clamped in the corresponding clamping hole 9 and unable to slide out, thereby making the corner key 4 clamped to the frame 1. The connection between the corner key 4 and the adjacent two frames 1 is strengthened through the sliding column 6, the spring 7, the clamping plate 8, etc., enhancing the installation stability of the photovoltaic module, preventing it from loosening and affecting the power generation efficiency and safety of the entire photovoltaic system, and prolonging the service life of the photovoltaic panel.

[0028] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
