Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic frames, and in particular relates to a photovoltaic installation frame. Background Art

[0002] PV panel frames are a crucial component of PV modules, primarily used to secure and seal the modules, enhance module strength, extend service life, and facilitate transportation and installation. Typically manufactured from aluminum, these frames undergo an anti-oxidation treatment using processes such as anodizing, electrophoresis, powder coating, PVDF, and sandblasting. Frame testing includes tensile strength, ductility, salt spray corrosion resistance, ammonia corrosion resistance, and curvature.

[0003] Currently, aluminum frames are widely used in photovoltaic modules, with a penetration rate exceeding 95%, and their price accounts for approximately 10% of the total module cost. However, aluminum frames represent a significant cost component, so reducing costs and improving weather resistance have long been a research priority. The emergence of composite material frames offers a new approach to addressing this issue. Composite material frames offer advantages such as low material cost, excellent weather resistance, insulation, and a lightweight, aesthetically pleasing design. They are 20% to 25% cheaper than aluminum frames and are expected to replace them in all scenarios in the future.

[0004] Currently, all photovoltaic frames on the market use a sealed installation structure. In a high-temperature environment, moisture will seep between the photovoltaic panels and the glass layer in front of the photovoltaic panels. Under the influence of the environment, the moisture will form water droplets and fog, which will block light from shining on the photovoltaic panels and affect the efficiency of the photovoltaic panels.

[0005] To address the aforementioned technical issues, this application employs a method that uses front-to-rear airflow to dissipate heat, removing moisture between the photovoltaic panel and the glass layer. This solves the technical problem of photovoltaic panels being blocked by mist or water droplets. Furthermore, the airflow facilitates heat dissipation, reducing the load on the photovoltaic panel. Furthermore, the bottom frame can be sealed with sealing tape when inserted, ensuring a complete seal when not in use, preventing the ingress of impurities and insects. Summary of the Invention

[0008] The bottom frame includes a two-layer mesh structure, the mesh structure includes an outer mesh and an inner mesh, the outer mesh and the bottom frame are connected in an integral structure, the bottom frame is provided with insertion holes along the left and right ends, and sealing tapes are inserted into the insertion holes;

[0009] An air supply component is installed on the top of the top frame.

[0010] Furthermore, the sealing belt is connected to the "U"-shaped hole through a "U"-shaped clip, and the "U"-shaped hole is opened on the extension plate body. The extension plate is an integrated structure extending horizontally to the right along the left end of the bottom frame.

[0011] Furthermore, an airflow gap is left between the outer network and the inner network, and the airflow gap is connected to the gap left between the photovoltaic panel and the protective layer.

[0012] Furthermore, the air supply assembly includes an air flow pump and an air supply connector;

[0014] Furthermore, a positioning groove is provided along one end of the extension plate of the bottom frame.

[0015] The beneficial effects of the utility model are:

[0016] Compared to existing technologies, this application utilizes a method that dissipates heat through front-to-rear airflow, removing moisture between the photovoltaic panel and the glass layer.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a photovoltaic mounting frame includes side frames, a top frame, and a bottom frame. A photovoltaic panel 9 is mounted between two sets of side frames 4. The top frame 5 and bottom frame 1 are mounted on the upper and lower ends of the photovoltaic panel 9, respectively. Both the bottom frame 1 and the top frame 5 are fixedly connected to the side frames 4 via mounting claws 10. The entire photovoltaic panel assembly is assembled using the two sets of side frames 4 and the top and bottom frames 5 and 1, providing the most basic protection.

[0023] The bottom frame 1 comprises a two-layer mesh structure, comprising an outer mesh 14 and an inner mesh 16. The outer mesh 14 is integrally connected to the bottom frame 1. Insertion holes 15 are defined along the left and right ends of the bottom frame 1, and sealing tape 17 is inserted into each insertion hole 15. The double-layer mesh structure of the bottom frame facilitates heat dissipation and ventilation within the photovoltaic panel 9. The double-layer design of the outer mesh 14 and inner mesh 16 enhances the structural strength of the mesh. Sealing tape 17 is inserted into the bottom frame 1 through the insertion holes 15 to seal the holes in the outer mesh 14 and inner mesh 16, preventing impurities and insects from entering the photovoltaic panel 9.

[0024] An air supply assembly is installed on the top of the top frame 5. The air supply assembly can provide airflow from top to bottom.

[0025] like Figure 1 and Figure 2 As shown, the sealing strip 17 is engaged with the U-shaped hole 13 via a U-shaped clip 18. The U-shaped hole 13 is provided in the extension plate 2, which extends horizontally and integrally to the right along the left end of the base frame 1. The U-shaped clip 18 cooperates with the U-shaped hole 13 to further secure the sealing strip 17, preventing it from being dislodged by external forces, airflow, or insects. The integrated connection of the extension plate 2 also strengthens its connection to the base frame 1, further stabilizing the installation of the sealing strip 17.

[0026] like Figure 1 and Figure 2 As shown, an airflow gap is left between the outer mesh 14 and the inner mesh 16, and the airflow gap is connected to the gap retained between the photovoltaic panel 9 and the protective layer 3. The airflow flows along the gap retained between the photovoltaic panel 9 and the protective layer 3, which can keep the interior dry and further reduce the temperature.

[0027] like Figure 1 and Figure 2 As shown, the air supply assembly includes an air flow pump 6 and an air supply connector 8;

[0028] The air flow pump 6 is connected to the air supply connector 8 through a pipeline. The air supply connector 8 is fixedly mounted on the outside of the top frame 5. The top frame 5 has a hollow air supply structure. The inner end of the top frame 5 retains an air groove, which is connected to the output port of the air supply connector 8. The air supply connector 8 can cooperate with the pipeline and the air flow pump 6 to deliver the supplied gas into the top frame 5. The hollow air supply structure of the top frame 5 can collect the three sections of the air supply connector 8 and evenly discharge them into the gap retained between the photovoltaic panel 9 and the protective layer 3.

[0029] like Figure 1 and Figure 2 As shown, the bottom frame 1 is provided with a positioning groove 12 along one end of the extension plate 2. The positioning groove 12 can cooperate with the bottom frames 1 produced in batches to complete the positioning, stacking, positioning and placement process, which is convenient for transportation.

[0030] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
