Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to the dustproof and waterproof structure of photovoltaic power station components. Background Technology

[0002] During actual operation, photovoltaic (PV) power plants are exposed to the outdoor environment for extended periods, making them highly susceptible to dust, rain, and other contaminants. Dust accumulation on the PV panel surface reduces its light absorption rate, leading to decreased power generation efficiency. Rainwater seeping into the PV panel can cause short circuits, damage to electronic components, and severely impact the lifespan and power generation stability of the PV panel. Currently, existing dustproof and waterproof measures for PV power plant modules have many shortcomings. Some modules use simple sealant to fill gaps, but over time, the sealant is prone to aging and cracking, significantly reducing its waterproof and dustproof effectiveness. Other modules achieve protection by adding protective shells, but the connection structure between the protective shell and the PV panel is complex, inconvenient to install and disassemble, and the protective effect is insufficient for long-term outdoor use.

[0003] Therefore, there is an urgent need to design a protective structure for photovoltaic power station modules that is simple in structure, easy to install, and can effectively provide dust and water protection for a long time. Utility Model Content

[0004] To overcome existing problems, this application provides a dustproof and waterproof structure for photovoltaic power station modules. Through the synergistic effect of components such as clips, protective films, and sealants, a tight fit is achieved between the photovoltaic panel and the frame, effectively blocking dust and rainwater from entering, improving the dustproof and waterproof performance of the photovoltaic modules, and ensuring the stable operation and power generation efficiency of the photovoltaic power station.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A dustproof and waterproof structure for photovoltaic power station modules includes a frame with a buckle at the top. The buckle is made of high-strength plastic and is fixedly connected to the frame by an integral molding method. A protective film is provided inside the buckle and the frame. A photovoltaic panel is located inside the frame and the buckle. A groove is formed on the lower surface of the buckle. The groove has an irregular structure and is recessed into the buckle. The groove is filled with sealant, which is silicone sealant, and the amount of sealant is higher than the surface of the groove. When the photovoltaic panel is connected to the buckle, the photovoltaic panel squeezes the protective film to make it adhere tightly to the surface of the photovoltaic panel, and the sealant forms a sealing layer in the groove. The protective film and the sealant work together to form a dustproof and waterproof barrier. The sealant forms a sealing layer in the groove. The protective film and the sealant work together to form a double dustproof and waterproof barrier, effectively preventing dust and rainwater from entering the photovoltaic module.

[0007] Preferably, the protective film is made of fluororubber. When the size of the photovoltaic panel changes, the protective film can adapt to the shape of the photovoltaic panel through elastic deformation and remain tightly attached. When the photovoltaic panel is connected to the buckle, the photovoltaic panel exerts a squeezing effect on the protective film, so that the protective film is tightly attached to the surface of the photovoltaic panel.

[0008] Preferably, the frame also includes reinforcing ribs to enhance its load-bearing capacity, and a support plate is provided on the top of the frame to support the photovoltaic panels. The support plate is made of aluminum alloy and is fixed to the top of the frame by integral molding.

[0009] The advantages of the embodiments of this application are:

[0010] 1. By tightly adhering the protective film to the photovoltaic panel and sealing it with the sealant, a dual protection system is formed. The protective film can fill tiny gaps under the pressure of the photovoltaic panel, while the sealant further seals the gaps between the frame and the clips. The two work together to effectively block dust particles and rainwater penetration, significantly improving the dustproof and waterproof performance of the photovoltaic module and extending its service life.

[0011] 2. The structure is mainly composed of components such as clips, frames, and protective films. The structural design is simple, and the installation methods of each component are clear. The photovoltaic panels only need to be connected to the frame through clips, without the need for complicated installation processes and tools, which reduces the installation difficulty and labor costs, improves installation efficiency, and facilitates large-scale application and maintenance.

[0012] 3. The protective film has good flexibility and elasticity, which can adapt to photovoltaic panels of different sizes and shapes. It automatically deforms and fits under the pressure of the photovoltaic panel to ensure the sealing effect. At the same time, the sealant can be selected with different specifications and performance products according to actual needs to meet the dustproof and waterproof requirements under different environmental conditions, making this structure suitable for various types of photovoltaic power station modules.

[0018] This application provides a dustproof and waterproof structure for photovoltaic power station modules, solving the problems in the prior art. Through the tight adhesion of the protective film to the photovoltaic panel and the sealing effect of the sealant, a dual protection system is formed. The protective film fills tiny gaps under the pressure of the photovoltaic panel, while the sealant further seals the gaps between the frame and the clips. Working together, they effectively block dust particles and rainwater penetration, significantly improving the dustproof and waterproof performance of the photovoltaic modules and extending their service life. The structure mainly consists of clips, a frame, and a protective film. The structural design is simple, and the installation methods for each component are clear. The photovoltaic panel only needs to be connected to the frame via clips, eliminating the need for complex installation processes and tools, reducing installation difficulty and labor costs, improving installation efficiency, and facilitating large-scale application and maintenance. The protective film has good flexibility and elasticity, adapting to photovoltaic panels of different sizes and shapes. It automatically deforms and fits under the pressure of the photovoltaic panel, ensuring a sealing effect. Simultaneously, the sealant can be selected from different specifications and performance products according to actual needs, meeting the dustproof and waterproof requirements under different environmental conditions, making this structure suitable for various types of photovoltaic power station modules.

[0019] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0020] Example

[0021] This embodiment provides a specific structure for the dustproof and waterproof design of photovoltaic power station modules, such as... Figure 1-2 As shown, the device includes a frame 3, with a buckle 1 on top of the frame 3. The buckle 1 is made of high-strength plastic and is fixedly connected to the frame 3 by an integral molding method. A protective film 4 is provided inside the buckle 1 and the frame 3. A photovoltaic panel 7 is installed inside the frame 3 and the buckle 1. A groove 5 is formed on the lower surface of the buckle 1. The groove 5 has an irregular structure and is recessed into the buckle 1. The groove 5 is filled with sealant 6, which is a silicone sealant, and the amount of sealant is higher than the surface of the groove 5. When the photovoltaic panel 7 is connected to the buckle 1, the photovoltaic panel 7 squeezes the protective film 4 to make it adhere tightly to the surface of the photovoltaic panel 7, and the sealant 6 forms a sealing layer in the groove 5. The protective film 4 and the sealant 6 work together to form a dustproof and waterproof barrier. A sealing layer is formed. The protective film 4 and the sealant 6 work together to form a double dustproof and waterproof barrier, effectively preventing dust and rainwater from entering the photovoltaic module. The photovoltaic panel 7 is placed steadily on the receiving plate 2, and the position of the photovoltaic panel 7 is adjusted to align it with the frame 3. Then, the photovoltaic panel 7 is pushed, and it engages with the buckle 1 during the movement. One end of the photovoltaic panel 7 contacts the protective film 4. Then, the protective film 4 is squeezed, and it undergoes elastic deformation to fit tightly against the side of the photovoltaic panel 7, forming the first dustproof and waterproof barrier. As the buckle 1 is tightened, the sealant 6 in the groove 5 is squeezed and fills the gap between the frame 3 and the buckle 1, forming a second sealing layer on the outside of the protective film 4, further enhancing the dustproof and waterproof effect.

[0022] The protective film 4 is made of fluororubber. When the size of the photovoltaic panel 7 changes, the protective film 4 can adapt to the shape of the photovoltaic panel 7 through elastic deformation and remain tightly attached. When the photovoltaic panel 7 is connected to the buckle 1, the photovoltaic panel 7 exerts a squeezing effect on the protective film 4, so that the protective film 4 is tightly attached to the surface of the photovoltaic panel 7.

[0023] The frame 3 also includes reinforcing ribs to enhance its load-bearing capacity. A support plate 2 is installed on top of the frame 3 to support the photovoltaic panel 7. The support plate 2 is made of aluminum alloy and is fixed to the top of the frame 3 in an integral molding manner.

[0024] By adopting the above technical solution:

[0025] The frame 3 is made of aluminum alloy and is precision machined. The inner width of the frame 3 is larger than that of the photovoltaic panel 7 to ensure that the photovoltaic panel 7 can be placed smoothly. The receiving plate 2 is made of aluminum alloy and is fixed to the bottom center of the frame 3 by welding. Neutral silicone sealant is loaded into the glue gun and evenly filled into the groove 5, with the filling height slightly higher than the surface of the groove 5.

[0026] Place the photovoltaic panel 7 stably on the receiving plate 2, ensuring that the four sides of the photovoltaic panel 7 are aligned with the inner edge of the frame 3. Then push the photovoltaic panel 7, and the photovoltaic panel 7 will engage with the buckle 1 during the movement. One end of the photovoltaic panel 7 will contact the protective film 4. Then squeeze the protective film 4, and the protective film 4 will undergo elastic deformation and tightly adhere to the side of the photovoltaic panel 7, forming the first dustproof and waterproof barrier.

[0027] As the buckle 1 and the photovoltaic panel 7 are tightened, the sealant 6 in the groove 5 is evenly squeezed out and overflows to fill the gap between the buckle 1 and the frame 3 and the tiny gap on the outside of the protective film 4, forming a uniformly thick sealing layer on the outside of the protective film 4, thus forming a second dustproof and waterproof barrier.

[0028] The photovoltaic modules with dustproof and waterproof structures were installed in an outdoor photovoltaic power station for testing. After three consecutive months of outdoor operation, including windy and sandy weather and multiple rainfalls, the surface of the photovoltaic panel 7 and the inside of the module were inspected by opening the clip 1. It was found that there was only a small amount of dust on the surface of the photovoltaic panel 7, and the inside of the module was dry and clean with no water ingress. The dustproof and waterproof effect was significant, effectively ensuring the normal power generation efficiency of the photovoltaic module.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
