In addition, these traditional structures may cause the frame to deform or be damaged due to thermal expansion and contraction during long-term use, affecting the stability and service life of the photovoltaic modules.

[0029] This embodiment provides a photovoltaic system that can be applied to various regions and buildings, which includes photovoltaic modules. In order to solve the problem that the photovoltaic modules in the prior art have poor thermal insulation performance, thereby reducing the overall thermal insulation effect of the photovoltaic system, this embodiment provides a photovoltaic connection frame, which is as follows:
[0030] like Figure 1 and Figure 2 As shown, the photovoltaic connection frame proposed in this embodiment includes a fixing seat 10, a support member 20, a heat insulating member 30 and a fastener 40; the fixing seat 10 is embedded and fixed on the wall 80, and the two support members 20 are respectively arranged on the left and right sides of the top surface of the fixing seat 10, and the heat insulating member 30 is arranged between the support member 20 and the fixing seat 10, and the fastener 40 connects the fixing seat 10, the support member 20, the heat insulating member 30 and the wall 80. In detail, the heat insulating member 30 in this embodiment is generally made of rubber and has a certain flexibility. In addition, the left and right sides of the top surface of the fixing seat 10 mentioned above specifically refer to: the cross-sectional shape of the fixing seat 10 is a concave shape, and the left and right sides of the top surface are based on the cross-sectional view.
[0031] It is understandable that the present embodiment greatly reduces heat loss through the provision of the heat insulating member 30, thereby improving the thermal efficiency of the system, which has a positive significance for improving the performance of the photovoltaic module; the design of the support member 20 can effectively disperse and withstand the weight of the photovoltaic module and external forces such as wind pressure, thereby ensuring the stability and service life of the photovoltaic module. Compared with the prior art, the combination of the support member 20 and the heat insulating member 30 not only avoids the damage to the module frame caused by thermal expansion and contraction, but also reduces the risk of deformation or damage caused by long-term uneven heating, thereby significantly improving the service life of the photovoltaic module.
[0032] In addition, the design of the fastener 40 of this embodiment realizes a stable connection between the fixing base 10, the support member 20, the heat insulating member 30 and the wall 80, ensuring the stability and durability of the entire structure. During long-term use, this structure is not prone to loosening, further enhancing the overall safety performance of the photovoltaic system.
[0033] Finally, this embodiment not only improves the thermal insulation effect and stability, but also takes into account the simplicity and economy of the structure. Its design is not only easy to install and maintain, but also has a relatively low production cost, meets the requirements of energy conservation and emission reduction, and embodies the green and environmentally friendly design concept.
[0034] In summary, this embodiment has obvious advantages over the prior art in terms of improving the thermal insulation effect, stability and service life of the photovoltaic system. Its beneficial effects are not only reflected in the improvement of technical performance, but also represent the new development trend of photovoltaic module installation structure, providing new technical support for the sustainable development of the photovoltaic industry.
[0035] In a preferred embodiment, the support member 20 is provided with a first connecting portion 21 and a second connecting portion 22, the cross-section of the first connecting portion 21 is L-shaped, and one side of the photovoltaic panel 70 is attached to the first connecting portion 21; the second connecting portion 22 is attached to the thermal insulation member 30 and is connected by a fastener 40.
[0036] It is understandable that the first connection portion 21 of the present embodiment adopts an L-shaped cross-section design, so that the photovoltaic panel 70 can fit tightly on the first connection portion 21, effectively improving the installation stability and force-bearing performance of the photovoltaic panel 70. At the same time, the good fit between the second connection portion 22 and the thermal insulation member 30 further ensures the firmness of the entire structure. The design of the present embodiment makes the installation process of the photovoltaic panel 70 easier and reduces the difficulty of installation. In addition, in the subsequent maintenance process, due to the simple structure, it is easy to carry out inspection and maintenance, thereby reducing the maintenance cost.
[0037] In an optional embodiment, the first connecting portion 21 includes a horizontal edge and a vertical edge, a rubber strip 23 connected to the photovoltaic panel 70 is provided on the horizontal edge, and a sealing strip 24 is provided on the vertical edge.
[0038] It is understandable that the design of the first connection portion 21 helps to improve the weather resistance of the photovoltaic panel 70 and prevent water ingress, oxidation and other problems caused by long-term exposure to outdoor environments. The use of the sealing strip 24 effectively isolates the connection portion from erosion by the external environment, thereby increasing the service life of the photovoltaic panel 70.
[0039] In addition, the structure has excellent adaptability and can be applied to photovoltaic panels 70 of different specifications and sizes, and has strong market competitiveness. In addition, while reducing production costs, the design is also conducive to saving raw materials and reducing waste emissions, which is in line with the development trend of green environmental protection.
[0040] In an optional embodiment, the photovoltaic connection frame further includes a water guide groove 50 , and two sides of the water guide groove 50 are respectively connected to two support members 20 .
[0041] In detail, by providing the water guide groove 50, rainwater or cleaning liquid can be effectively guided to flow to the outside of the frame, reducing the accumulation of water inside the photovoltaic module, thereby reducing the corrosion risk of the frame and the module due to water vapor erosion, and extending the service life of the photovoltaic module.
[0042] In addition, the design of the water channel 50 is not only conducive to drainage, but also increases the connection stability between the frame and the support member 20, reduces the frame deformation caused by temperature difference, and ensures the structural stability and long-term reliability of the photovoltaic system.
[0043] In an optional embodiment, a mounting groove 25 is provided on the support member 20 , and socket strips 51 inserted into the mounting groove 25 are provided on both sides of the water guide groove 50 .
[0044] The installation structure of this embodiment effectively solves the problems of unstable installation and easy falling of the water guide groove 50, thereby improving the reliability of the overall structure. In addition, due to the design of the installation groove 25, the installation and removal process of the water guide groove 50 becomes simple and fast, reducing maintenance costs and improving work efficiency.
[0045] Secondly, the water guide groove 50 of this embodiment is provided with plug-in strips 51 inserted into the installation groove 25 on both sides. This design not only ensures the straightness of the water guide groove 50, but also avoids the problem of poor drainage caused by deformation of the water guide groove 50 itself or improper installation.
[0046] In an optional embodiment, the middle portion of the water guide groove 50 is in a concave shape, the shape of the fixing seat 10 is also in a concave shape, and the water guide groove 50 is located in the fixing seat 10 .
[0047] In particular, due to the design of the concave-shaped structure, the water guiding efficiency of the water guide groove 50 is significantly improved. Under the same conditions, compared with the prior art, this embodiment can more effectively guide the water flow, reduce the impact of the water flow on the side wall of the water guide groove 50, and reduce the wear of the water flow on the material of the water guide groove 50.
[0048] In an optional embodiment, the water channel 50 is made of rubber or plastic. Since rubber or plastic materials have good anti-aging, anti-ultraviolet and corrosion resistance, the service life of the water channel 50 of this embodiment is significantly better than that of traditional water channels 50 made of metal or other materials.
[0049] In an optional embodiment, the photovoltaic connection frame further includes a wiring frame 60 , and the wiring frame 60 is connected to the bottom of the fixing seat 10 by bolts.
[0050] The photovoltaic connection frame provided in this embodiment has the following advantages:
[0051] This embodiment greatly reduces heat loss by setting the heat insulation member 30, thereby improving the thermal efficiency of the system, which has a positive significance for improving the performance of photovoltaic modules; the design of the support member 20 can effectively disperse and withstand the weight of the photovoltaic module and external forces such as wind pressure, thereby ensuring the stability and service life of the photovoltaic module. Compared with the prior art, the combination of the support member 20 and the heat insulation member 30 not only avoids the damage to the module frame caused by thermal expansion and contraction, but also reduces the risk of deformation or damage caused by long-term uneven heating, thereby significantly improving the service life of the photovoltaic module.
