Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel protection technology, and more specifically, to a protective structure for photovoltaic panels. Background Technology

[0002] With the growing global demand for renewable energy, photovoltaic energy is gaining increasing attention as a clean and sustainable energy solution. Photovoltaic panels are key equipment for converting solar energy into electricity, but they are exposed to the outdoor environment for extended periods, facing multiple challenges such as wind and sand erosion, temperature variations, and ultraviolet radiation.

[0003] Existing photovoltaic (PV) panel installation methods are not stable enough. Under the influence of external forces such as strong winds and earthquakes, PV panels are prone to swaying, displacement, or even detachment, which not only affects power generation efficiency but may also pose safety hazards. Furthermore, during heat transfer, due to the poor thermal insulation performance of the protective structure, heat easily accumulates on the back of the PV panel, leading to excessively high temperatures on the back of the panel. This can damage internal components, such as accelerating backsheet aging, degrading cell performance, and severely shortening the lifespan of the PV panel.

[0004] Meanwhile, photovoltaic panels suffer from insufficient installation stability and are easily affected by the external environment. In addition, during heat transfer, heat tends to accumulate at the frame of the photovoltaic panel, causing the back temperature to rise, which in turn causes thermal damage to the electronic components on the back, affecting the overall efficiency and service life.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a protective structure for photovoltaic panels to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A protective structure for photovoltaic panels includes a protective frame installed on the outer wall of the photovoltaic panel; a protective component disposed on one side of the protective frame for protecting the photovoltaic panel; a plurality of hinges movably connected between the protective frame and the protective component; and a plurality of latches disposed on one side of the protective frame and the protective component.

[0008] Furthermore, in order to effectively protect the photovoltaic panel, the protective component includes a mounting frame set on one side of the protective frame, with a transparent plate on one side of the mounting frame; and a sealing gasket that cooperates with the protective frame on the other side of the mounting frame.

[0009] Furthermore, in order to improve the thermal performance and structural strength of the protective frame and effectively reduce the temperature accumulation on the back of the photovoltaic panel, the protective frame includes a front frame and a rear frame set on both sides of the outer wall of the photovoltaic panel. The front frame and the rear frame are connected in sequence by a first thermal break bridge, a second thermal break bridge, a third thermal break bridge and a fourth thermal break bridge. Filling blocks are set between the first thermal break bridge, the second thermal break bridge, the third thermal break bridge and the fourth thermal break bridge. Several weight-reducing cavities are opened on both the front frame and the rear frame. A placement plate that cooperates with the photovoltaic panel is set at one end of the first thermal break bridge.

[0010] Furthermore, in order to improve the overall structure's wind pressure resistance and protection level, sealing strips that cooperate with the photovoltaic panels are installed on the opposite sides of both the front and rear frames.

[0011] Furthermore, in order to improve the reliability of the connection between the front and rear frames, the front frame consists of an upper frame, a middle frame and a lower frame; the lower frame and the middle frame are spliced ​​together by U-shaped and F-shaped bayonet joints; the middle frame and the upper frame are spliced ​​together by L-shaped locking blocks; the middle frame and the lower frame are each provided with a number of first locking blocks on the side facing the rear frame, and the first locking blocks are set in a trapezoidal structure.

[0012] Furthermore, in order to achieve rapid assembly and secure connection between the thermal break bridge and the front and rear frames, the first, second, third, and fourth thermal break bridges are all equipped with second locking blocks on both sides that cooperate with the first locking block.

[0013] Furthermore, to ensure accurate positioning and secure connection of the thermal break during installation, the gap between two adjacent sets of first clips matches the shape and size of the second clip.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model has a reasonable and reliable structure and is simple to operate. Through the synergistic effect of the protective components and the protective frame, it provides comprehensive protection for the photovoltaic panel. The protective components, relying on the rigid support of the mounting frame for the transparent panel, form a solid protective barrier, while the protective frame effectively blocks heat transfer, reducing the temperature of the components on the back of the photovoltaic panel in hot weather. Together, they improve the environmental adaptability and operational stability of the photovoltaic panel, effectively extending the equipment's lifespan.

[0015] 2. This utility model, by incorporating protective components, achieves multi-dimensional protection for photovoltaic panels without affecting their normal light absorption. The rigid support of the mounting frame for the transparent panel forms a robust protective barrier, resisting impacts from hail, sandstorms, and other external forces, preventing breakage of the original glass cover and microcracks in the solar cells. It also prevents the direct adhesion of dust, fallen leaves, and other foreign objects, thus preventing localized hot spot effects. Simultaneously, the sealing gasket filling the gap between the mounting frame and the protective frame effectively blocks rainwater and salt spray intrusion, preventing corrosion of the internal backsheet and oxidation of the circuitry, further ensuring the stable operation of the photovoltaic panel.

[0016] 3. This utility model, by setting up a protective frame, can effectively block heat transfer, reducing the temperature of various components on the back of the photovoltaic panel in hot weather. At the same time, the structural design of the protective frame enhances the overall wind pressure resistance, achieving a balance between lightweight and robust photovoltaic panel protection structure, improving the environmental adaptability and operational stability of the photovoltaic panel, and thus effectively extending the service life of the equipment.

Detailed Implementation

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0021] According to an embodiment of the present invention, a protective structure for photovoltaic panels is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, a protective structure for a photovoltaic panel according to an embodiment of the present utility model includes a protective frame 1, which is installed on the outer wall of the photovoltaic panel; a protective component 2, which is disposed on one side of the protective frame 1 for protecting the photovoltaic panel; a plurality of hinges 3, which are movably connected between the protective frame 1 and the protective component 2; and a plurality of latches 4, which are disposed on one side of the protective frame 1 and the protective component 2.

[0023] By utilizing the aforementioned technical solution, the protective component 2 and the protective frame 1 work together to provide comprehensive protection for the photovoltaic panel. The protective component 2, relying on the rigid support of the mounting frame 201 for the transparent panel 202, forms a robust protective barrier. Meanwhile, the protective frame 1 effectively blocks heat transfer, reducing the temperature of the components on the back of the photovoltaic panel in hot weather. Together, they enhance the environmental adaptability and operational stability of the photovoltaic panel, effectively extending the equipment's lifespan.

[0024] It should be noted that the Transparent Panel 202 uses UV-resistant and high-temperature resistant PC board with a light transmittance of over 90%, ensuring that sunlight efficiently reaches the photovoltaic panel to meet the photoelectric conversion requirements. The PC board has built-in UV stabilizers to resist long-term ultraviolet radiation, preventing the panel from yellowing and cracking, and it can withstand extreme temperatures, making it suitable for outdoor temperature difference conditions and preventing structural deformation. The surface of the Transparent Panel 202 is coated with a nano-level transparent ceramic coating. The coating is transparent and does not affect light transmission. It not only improves surface hardness, but also allows rainwater to carry away impurities due to its hydrophobic properties, and it can also enhance high-temperature resistance and assist in heat dissipation.

[0025] In one embodiment, the protective component 2 includes a mounting frame 201 disposed on one side of the protective frame 1, a transparent plate 202 disposed on one side of the mounting frame 201, and a sealing gasket 203 that cooperates with the protective frame 1 disposed on the other side of the mounting frame 201. This effectively protects the photovoltaic panel.

[0026] In one embodiment, the protective frame 1 includes a front frame 101 and a rear frame 102 disposed on both sides of the outer wall of the photovoltaic panel. The front frame 101 and the rear frame 102 are connected sequentially by a first thermal break 103, a second thermal break 104, a third thermal break 105, and a fourth thermal break 106. A filler block 117 is disposed between each of the first thermal break 103, the second thermal break 104, the third thermal break 105, and the fourth thermal break 106. Several weight-reducing cavities 118 are provided on both the front frame 101 and the rear frame 102. A placement plate 107 that cooperates with the photovoltaic panel is disposed at one end of the first thermal break 103. This improves the thermal performance and structural strength of the protective frame 1 and effectively reduces temperature accumulation on the back of the photovoltaic panel.

[0027] In one embodiment, for the aforementioned front frame 101, both the front frame 101 and the rear frame 102 have sealing strips 108 that cooperate with the photovoltaic panels on opposite sides. This improves the overall structure's wind pressure resistance and protection level.

[0028] In one embodiment, the front frame 101 comprises an upper frame 109, a middle frame 110, and a lower frame 111. The lower frame 111 is connected to the middle frame 110 via U-shaped latches 112 and F-shaped latches 113. The middle frame 110 is connected to the upper frame 109 via L-shaped latches 114. Several first latches 115, each trapezoidal in shape, are provided on the side of the middle frame 110 and the lower frame 111 facing the rear frame 102. This improves the reliability of the connection between the front and rear frames.

[0029] In one embodiment, for the first thermal break 103, the first thermal break 103, the second thermal break 104, the third thermal break 105, and the fourth thermal break 106 are all provided with second locking blocks 116 on both sides to cooperate with the first locking block 115. This enables rapid assembly and secure connection between the thermal break and the front and rear frames.

[0030] In one embodiment, for the aforementioned first locking block 115, the gap space formed between two adjacent sets of first locking blocks 115 matches the shape and size of the second locking block 116. This ensures accurate positioning and secure connection of the thermal break during installation.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] like Figures 1-4 As shown, in practical applications, a section of the rear frame 102 is installed on the outer wall of one side of the photovoltaic panel. The first locking block 115 on the rear frame 102 and the second locking block 116 on the thermal break bridge sequentially connect the first thermal break bridge 103, the second thermal break bridge 104, the third thermal break bridge 105, and the fourth thermal break bridge 106, achieving a stable assembly of the thermal insulation structure. Next, through the cooperation of the first locking block 115 and the second locking block 116, the lower frame 111 is installed to the front end of each thermal break bridge, completing the assembly of the bottom of the front frame.

[0033] The middle frame 110 is slidably spliced ​​with the lower frame 111 via the U-shaped latch 112 at its bottom and the F-shaped latch 113 at its top, achieving quick locking and connection between the upper and lower frames. Then, the middle frame 110 is horizontally spliced ​​via the L-shaped latch 114 set between the middle frame 110 and the upper frame 109, completing the complete assembly of the front frame 101 on this side, thereby achieving firm coverage and fixation of one edge of the photovoltaic panel, forming a complete protective frame 1.

[0034] The remaining three protective frames 1 are assembled in the same way, and adjacent protective frames 1 are vertically connected and fastened at the corners using special corner brackets to achieve a closed encapsulation of the photovoltaic panel around the perimeter, ensuring the stability and sealing of the overall structure.

[0035] Several hinges 3 are installed on one side of the protective frame 1, and the mounting frame 201 is connected to the protective frame 1 via the hinges 3. A latch 4 is provided on the other side of the mounting frame 201, which is locked to the corresponding fasteners on the protective frame 1, achieving an openable and closable closure of the mounting frame 201. In the closed state, the sealing gasket 203 on the mounting frame 201 fits tightly against the protective frame 1, effectively preventing dust, rainwater, and other impurities from entering the interior, ensuring a clean operating environment for the photovoltaic panel. Meanwhile, the transparent plate 202 on the outside of the mounting frame 201 is made of a high-transmittance, weather-resistant material, providing physical protection for the photovoltaic panel without affecting light absorption, ensuring its long-term stable and efficient operation.

[0036] In summary, by utilizing the above-mentioned technical solution of this utility model, the protective component 2 and the protective frame 1 work together to provide comprehensive protection for the photovoltaic panel. Specifically, the protective component 2, relying on the rigid support of the mounting frame 201 for the transparent plate 202, forms a solid protective barrier. The protective frame 1 effectively blocks heat transfer, reducing the temperature of the components on the back of the photovoltaic panel in hot weather. Together, they improve the environmental adaptability and operational stability of the photovoltaic panel, effectively extending the equipment's lifespan. This utility model, by setting up the protective component 2, can achieve multi-dimensional protection for the photovoltaic panel without affecting its normal light absorption. The rigid support of the mounting frame 201 for the transparent plate 202 forms a solid protective barrier, which can resist external impacts such as hail and sandstorms, preventing the original glass cover of the photovoltaic panel from cracking and the cells from microcracks, and also prevents the direct adhesion of foreign objects such as dust and fallen leaves, thereby preventing the generation of localized hot spots. Simultaneously, the sealing gasket 203 fills the gap between the mounting frame 201 and the protective frame 1, effectively blocking the intrusion of rainwater and salt spray, preventing corrosion of the internal back panel of the photovoltaic panel and oxidation of the circuitry, further ensuring the stable operation of the photovoltaic panel. This invention, by setting up a protective frame 1, can effectively block heat transfer, reducing the temperature of various components on the back of the photovoltaic panel in hot weather. At the same time, the structural design of the protective frame 1 enhances the overall wind pressure resistance, achieving a balance between lightweight and robust photovoltaic panel protection structure, improving the environmental adaptability and operational stability of the photovoltaic panel, and thus effectively extending the service life of the equipment.
