Description
Technical Field
[0001] This utility model belongs to the technical field of photovoltaic modules, specifically relating to a dust-proof frame for a photovoltaic panel. Background Technology
[0002] Solar photovoltaic (PV) modules are a technology that directly converts solar energy into electrical energy. They convert light energy into electrical energy through the radiation of sunlight, using solar panels made of semiconductor materials to absorb light energy and convert it into direct current. The frame of the PV module is a supporting structure installed around the solar panel, mainly used to fix and protect the fragile parts inside the PV panel, such as glass, solar cells, and backsheet. It is usually made of aluminum alloy, which is lightweight, corrosion-resistant, and high-strength. It can effectively resist external mechanical stresses such as wind pressure and snow load, while facilitating the installation and fixing of the module. The standardized structure of the frame allows PV panels to be easily integrated into various support systems, adapting to different installation scenarios such as rooftops and ground.
[0003] However, after installation, if it rains, the accumulated rainwater at the bottom of the photovoltaic modules cannot drain away. After the water evaporates, it will form stains at the bottom, which will block the solar cells, affect the power generation, and even damage the photovoltaic modules. Utility Model Content
[0004] The purpose of this utility model is to provide a dust-proof frame for photovoltaic panels, in order to solve the problem mentioned in the background art that, after installation, if it rains, the rainwater accumulates at the bottom and cannot drain away. After the water evaporates, it forms stains at the bottom, which in turn obstructs the solar cells, affects the power generation, and may even damage the photovoltaic modules.

The long side component has a long side A surface at the top, a second groove wall below the long side A surface, a long side B surface on the side of the long side component, and a long side C surface at the bottom of the long side component. The short side component and the long side component are connected by a corner bracket. The second tank wall is provided with multiple drainage grooves, the upper surface of the second tank wall is provided with anti-slip ridges, the second tank wall is provided with an inner slope, a water guide groove is provided between the inner slope and the anti-slip ridges, an overflow glue groove is provided at the bottom of the short side A surface and the long side A surface, and corner overflow glue grooves are provided at the angles between the short side A surface, the long side A surface and the second tank wall and the short side B surface and the long side B surface, respectively. A pair of reinforcing inclined plates are provided at the top and bottom of the short side component and the long side component, respectively. Two reinforcing ridges are provided at the bottom of the second tank wall, and two reinforcing ridges are also provided at the upper surface of the short side C surface and the long side C surface. A base plate is provided at the bottom of the long side component, and multiple fixing holes are provided on the base plate.
[0006] Preferably, the long side component and the short side component are each cut at two ends. The A side of the long side component and the short side component are cut parallel to the port edge with a length of 5mm. The B side of the long side component and the short side component are cut to a depth of 3mm at the position corresponding to the A side. After the long side component and the short side component are assembled into a photovoltaic module with a frame, there is a water inlet at each of the four corners.
[0007] Preferably, the water inlet is an opening located at the connection between the short-side module and the long-side module. The water inlet can effectively carry away dust with rainwater, preventing dust from accumulating on the bottom of the photovoltaic module.
[0008] Preferably, the drainage channels are equidistantly arranged on the second channel wall, and the drainage channels adopt an outward inclined slope design. The drainage channels can drain the water that seeps into the connection between the photovoltaic panel and the short-side module and the long-side module.
[0009] Preferably, the drainage channel is connected to the water guide channel, and the drainage channel and the water guide channel are integrally formed with the second channel wall. The water guide channel can collect the water in the component, making it convenient for the drainage channel to drain the water.
[0010] Preferably, the anti-slip ridge is integrally formed with the second groove wall. The anti-slip ridge can increase the friction between the photovoltaic panel and the second groove wall. The overflow glue groove and the corner overflow glue groove can provide redundant space for the glue applied during installation and prevent the glue from overflowing from the photovoltaic module onto the surface of the photovoltaic panel.
[0011] Preferably, the reinforcing inclined plate is welded to the short side component, and the reinforcing rib is welded to the second groove wall, the short side C-surface, and the long side C-surface respectively. The reinforcing inclined plate and the reinforcing rib can improve the structural strength of the short side component and the long side component.
[0012] Compared with the prior art, the present invention provides a dust-proof frame for photovoltaic panels, which has the following advantages: 1. By setting up water inlets, drainage channels, and water guide channels, accumulated water on the installed components can be diverted away, and dust can be carried away, thus preventing dust accumulation. The openings formed at the four corners of the frame by the water inlets can use rainwater to wash away fine dust particles deposited on the edge of the frame, effectively preventing dust from accumulating at the bottom of the components. The drainage channels, which are evenly distributed and have outward inclined surfaces, ensure the rapid diversion and discharge of accumulated water. The water guide channels build directional water flow channels inside the components, so that the infiltrated water can be orderly collected and discharged into the drainage channels. These drainage structures can promptly remove rainwater accumulated at the bottom of the photovoltaic components, preventing the formation of stains after water evaporation that obstruct the solar cells. This not only ensures power generation efficiency but also extends the service life of the photovoltaic panels.
[0013] 2. By setting anti-slip ridges, corner overflow grooves, reinforcing bevels, and reinforcing ridges, the anti-slip ridges significantly enhance the frictional resistance between the photovoltaic panel and the groove wall, effectively preventing displacement problems during installation and use. The corner overflow grooves provide reasonable space for the installation glue, ensuring sealing while preventing glue overflow and contamination of the panel surface. The reinforcing bevels and reinforcing ridges connected by welding process make the various components of the frame form a rigid whole, greatly improving the bending and deformation resistance.

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.
[0022] This utility model provides, for example Figure 1-6 The image shows a dust-proof frame for a photovoltaic panel, comprising a pair of short-side components 1 and a pair of long-side components 10. The short side component 1 has a short side A surface 4 on its top, a second groove wall 5 below the short side A surface 4, a short side B surface 9 on one side of the second groove wall 5 and the short side A surface 4, and a short side C surface 18 on its bottom. The long side component 10 has a long side A surface 12 on its top, a second groove wall 5 below the long side A surface 12, a long side B surface 15 on one side of the long side component 10, and a long side C surface 16 on its bottom. The short side component 1 and the long side component 10 are connected by a corner bracket 17. Multiple drainage channels 8 are provided on the second tank wall 5. Anti-slip ridges 6 are provided on the upper surface of the second tank wall 5. Inner inclined surfaces 7 are provided on the second tank wall 5. Water guide channels 19 are provided between the inner inclined surfaces 7 and the anti-slip ridges 6. Overflow glue channels 13 are provided at the bottom of the short side A surface 4 and the long side A surface 12. Corner overflow glue channels 14 are provided at the angles between the short side A surface 4, the long side A surface 12 and the second tank wall 5 and the short side B surface 9 and the long side B surface 15, respectively. A pair of reinforcing inclined plates 2 are provided at the top and bottom of the short side component 1 and the long side component 10, respectively. Two reinforcing ridges 3 are provided at the bottom of the second tank wall 5. Two reinforcing ridges 3 are also provided on the upper surfaces of the short side C surface 18 and the long side C surface 16. A base plate 11 is provided at the bottom of the long side component 10. Multiple fixing holes 20 are provided on the base plate 11.
[0023] In this embodiment, the photovoltaic panel frame is a support structure installed around the solar panel, mainly used to fix and protect the fragile parts inside the photovoltaic panel such as glass, cells, and backsheet. It is usually made of aluminum alloy, which is lightweight, corrosion-resistant, and high-strength, and can effectively resist external mechanical stresses such as wind pressure and snow load. At the same time, it facilitates the installation and fixing of the module. The photovoltaic panel frame is used as follows: the short side component 1 and the long side component 10 cooperate to form a rectangular frame structure. The short side A surface 4 of the short side component 1 and the long side A surface 12 of the long side component 10 together form the upper support surface of the photovoltaic panel. The short side C surface 18 and the long side C surface 16 serve as the bottom support surface and are fixed to the installation foundation. During the installation process, the corner bracket 17 is first inserted into the connection part of the short side component 1 and the long side component 10, and the overall frame is formed by bolts. Then, the photovoltaic panel is embedded into the installation area formed by the short side A surface 4 and the long side A surface 12, and finally the assembly is completed.
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the long-side component 10 and the short-side component 1 are each cut at two ends. The A-side of the long-side component 10 and the short-side component 1 are cut parallel to the edge of the port with a length of 5mm. The B-side of the long-side component 10 and the short-side component 1 are cut to a depth of 3mm at the position corresponding to the A-side. After the long-side component 10 and the short-side component 1 are assembled into a photovoltaic module with a frame, there is a water inlet 21 at each of the four corners. The water inlet 21 is an opening set at the connection between the short-side component 1 and the long-side component 10. The water inlet 21 can effectively carry away dust with rainwater and prevent dust from accumulating at the bottom of the photovoltaic module. The drainage channel 8 is equidistantly set on the second channel wall 5. The drainage channel 8 adopts an outward inclined slope design. The drainage channel 8 can drain the water that seeps into the connection between the photovoltaic panel and the short-side component 1 and the long-side component 10. The drainage channel 8 is connected to the water guide channel 19. The drainage channel 8 and the water guide channel 19 are integrally formed with the second channel wall 5. The water guide channel 19 can collect the water in the module, which is convenient for the drainage channel 8 to drain the water.
[0025] Preferably, the water inlet 21, drainage channel 8, and water channel 19 are designed to drain water from the installed components and remove dust, thus preventing dust accumulation. The four corner openings formed by the water inlet 21 after the frame assembly can effectively remove dust with rainwater and wash away fine dust particles deposited on the edge of the frame, preventing dust from accumulating at the bottom of the components. The equidistant distribution and outward sloping design of the drainage channel 8 ensure rapid drainage of accumulated water. The water channel 19 can form a directional water flow channel inside the components, allowing infiltrated water to collect along the water channel 19 and drain out into the drainage channel 8. This drainage structure of the photovoltaic module can promptly guide and drain rainwater accumulated at the bottom of the photovoltaic module, preventing water from evaporating and forming stains at the bottom that obstruct the solar cells, affecting power generation and preventing damage to the photovoltaic module.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-slip rib 6 is integrally formed with the second groove wall 5. The anti-slip rib 6 can improve the friction between the photovoltaic panel and the second groove wall 5. The overflow glue groove 13 and the corner overflow glue groove 14 can provide redundant space for the glue applied during installation, preventing the glue from overflowing from the photovoltaic module to the surface of the photovoltaic panel. The reinforcing inclined plate 2 is welded to the short side module 1. The reinforcing rib 3 is welded to the second groove wall 5, the short side C surface 18 and the long side C surface 16 respectively. The reinforcing inclined plate 2 and the reinforcing rib 3 can improve the structural strength of the short side module 1 and the long side module 10.
[0027] Preferably, by setting the anti-slip rib 6, the corner overflow groove 14, the reinforcing inclined plate 2, and the reinforcing rib 3, the reinforcing rib 3 can effectively increase the frictional resistance between the photovoltaic panel and the second groove wall 5, preventing the photovoltaic panel from shifting or sliding during installation or use, and ensuring the long-term stable operation of the module. The corner overflow groove 14 provides sufficient space for the glue during the installation process, avoiding glue overflow and contaminating the surface of the photovoltaic panel, which not only ensures the sealing effect but also improves the aesthetics. The reinforcing inclined plate 2 and the reinforcing rib 3 form a rigid connection with the short side module 1, the second groove wall 5, the short side C surface 18, and the long side C surface 16 by welding, which significantly improves the overall bending and deformation resistance of the frame, especially under severe weather conditions, it can effectively resist wind pressure and snow load. The synergistic effect of these structures makes the dust-proof module frame have both installation stability, sealing reliability, and structural durability.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
