Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-5 The photovoltaic module anti-dust frame shown includes a frame body 1;

[0025] A photovoltaic panel 2 is installed in the middle of the interior of the frame body 1, and an outer frame 3 is installed on the outer side of the frame body 1.

[0026] An outer frame strip 6 is arrayed inside the outer frame 3, and a slot 7 is provided in the middle of the outer frame strip 6.

[0027] The outer frame strip 6 has outer grooves 12 on its upper and lower sides, and an inner cavity 13 is provided inside the outer frame strip 6.

[0028] Side openings 10 are provided on the upper and lower sides of the inner cavity 13. The inner cavity 13 and the outer groove 12 are connected through the side openings 10. Rainwater enters the inner cavity 13 through the outer groove 12 and then flows out of the outer frame 3.

[0029] The card slot 7 has an array of flow guide grooves 11 inside, and the inside of the flow guide grooves 11 is coated with waterproof paint.

[0030] An inner frame 4 is provided inside the outer frame 3, and inner frame strips 5 are arranged in an array inside the inner frame 4.

[0031] An inner groove 8 is provided in the middle of the inner frame strip 5, and side grooves 9 are provided on the upper and lower sides of the inner frame strip 5. Rainwater enters the guide groove 11 through the side grooves 9.

[0032] The inner groove 8 is snapped to the photovoltaic panel 2, the outer frame 3 is snapped to the inner frame 4, and the outer frame strips 6 and the inner frame strips 5 are connected by welding.

[0033] In this embodiment, a specific implementation step of a photovoltaic module anti-dust frame is as follows: the photovoltaic panel 2 is installed in the inner groove 8 of the inner frame 4, and then the inner frame 4 and the outer frame 3 are fixed by the slot 7. When it rains, the internal rainwater flows into the guide groove 11 through the side groove 9, and the external rainwater enters the inner cavity 13 through the outer groove 12. Finally, the rainwater flows out from the outer frame 3.

[0034] like Figures 1-2 and Figure 5 As shown, an outer frame strip 6 is arranged in an array inside the outer frame 3. A slot 7 is provided in the middle of the outer frame strip 6. Outer grooves 12 are provided on the upper and lower sides of the outer frame strip 6. An inner cavity 13 is provided inside the outer frame strip 6. Side openings 10 are provided on the upper and lower sides of the inner cavity 13. The inner cavity 13 and the outer groove 12 are connected through the side openings 10. Rainwater enters the inner cavity 13 through the outer groove 12 and then flows out of the outer frame 3. A guide channel 11 is arranged in an array inside the slot 7. The inside of the guide channel 11 is coated with waterproof paint.

[0035] Preferably, the outer grooves 12 on the upper and lower sides of the outer frame strip 6 provide channels for rainwater to enter. After the rainwater flows into the outer grooves 12, it can smoothly enter the inner cavity 13 through the side openings 10. This design allows the rainwater to be quickly guided to a specific discharge path, avoiding accumulation on the surface of the frame and reducing the possibility of dust adhering due to water accumulation. The inner cavity 13 inside the outer frame strip 6 serves to store and guide rainwater. After entering the inner cavity 13, the rainwater can quickly flow out of the outer frame 3, ensuring the dryness of the frame and reducing the risk of dust accumulation. The guide channel 11 inside the slot 7 further optimizes the flow path of the rainwater, allowing the rainwater to be discharged more smoothly. At the same time, the waterproof paint sprayed inside the guide channel 11 can not only prevent the guide channel 11 from rusting and corroding, but also ensure the smooth flow of rainwater and extend the service life of the frame.

[0036] like Figure 1 and Figures 3-4 As shown, an inner frame 4 is provided inside the outer frame 3, an inner frame strip 5 is arranged in an array inside the inner frame 4, an inner groove 8 is provided in the middle of the inner frame strip 5, and side grooves 9 are provided on the upper and lower sides of the inner frame strip 5. Rainwater enters the guide channel 11 through the side grooves 9.

[0037] Preferably, an inner frame 4 is set inside the outer frame 3 to form a double-layer structure, which increases the stability and protection of the frame. The inner frame 4 can better fix the photovoltaic panel 2 and reduce the impact of external factors on the photovoltaic panel. The inner groove 8 inside the inner frame strip 5 can be tightly engaged with the photovoltaic panel 2 to ensure the installation of the photovoltaic panel firmly. The side grooves 9 on the upper and lower sides of the inner frame strip 5 provide a channel for rainwater to enter the drainage channel 11, so that rainwater can be guided and discharged in time, avoiding accumulation on the frame and reducing the possibility of dust accumulation. At the same time, this design also helps to improve drainage efficiency and protect the photovoltaic panel from rainwater erosion.

[0038] like Figures 1-5 As shown, the inner groove 8 is snapped to the photovoltaic panel 2, the outer frame 3 is snapped to the inner frame 4, and the outer frame strips 6 and the inner frame strips 5 are connected by welding.

[0039] Optionally, the inner groove 8 is snap-fitted to the photovoltaic panel 2, making the installation of the photovoltaic panel more convenient and stable. The snap-fit ​​method facilitates installation and disassembly, improving installation efficiency, and also ensures that the photovoltaic panel will not easily loosen during use, guaranteeing the stability and reliability of the photovoltaic module. The outer frame 3 is snap-fitted to the inner frame 4. This connection method not only facilitates assembly and disassembly, but also allows for flexible adjustment according to different needs. During transportation and storage, the outer frame and inner frame can be separated, reducing space occupation and facilitating handling. During installation, the snap-fit ​​connection enables quick positioning and improves installation accuracy. The outer frame strips 6 and the inner frame strips 5 are connected by welding, making the overall structure of the frame more robust. The welded connection can withstand greater external forces, improving the strength and stability of the frame, thereby better protecting the photovoltaic panel and extending the service life of the photovoltaic module.
