A self-protecting photovoltaic module

Abstract

This utility model belongs to the field of photovoltaic technology and discloses a self-protective photovoltaic module, including a frame, an mounting plate installed on the top of the frame, a photovoltaic panel installed on the top of the mounting plate, and a protective frame for all-weather protection of the photovoltaic panel. The protective frame includes a frame and tempered glass circumferentially connected to the frame. The tempered glass can effectively resist impacts from hail or flying stones in severe weather, preventing damage to the photovoltaic panel. Light can pass through the tempered glass to reach the photovoltaic panel, allowing it to generate electricity normally. Ear plates are installed at the corners of the mounting plate, and fixing rods are installed at the corners of the frame. Each ear plate corresponds to a fixing rod, which passes through the corresponding ear plate. A locking rod is rotatably installed at the end of the fixing rod furthest from the frame. Rotating the locking rod locks it to the bottom of the ear plate, completing the installation of the protective frame. Disassembly only requires rotating the locking rod in the opposite direction to remove the protective frame, resulting in high installation and disassembly efficiency. The manufacturing and material costs of the protective frame's installation structure are low, reducing installation costs.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a self-protective photovoltaic module. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are the most basic power generation unit in a photovoltaic power generation system. They are the core components that convert solar energy into electrical energy. A photovoltaic panel is composed of multiple solar cells combined through certain electrical connections and encapsulation processes. Solar cells utilize the photovoltaic effect of semiconductor materials to directly convert light energy into electrical energy. Common semiconductor materials include thin film materials such as monocrystalline silicon, polycrystalline silicon, and amorphous silicon.

[0003] Photovoltaic modules are typically installed outdoors and are exposed to the natural environment for extended periods, making them susceptible to various severe weather conditions. Hail, heavy rain, and blizzards can cause physical damage to the modules, such as damaging the surface or deforming them. A utility model patent with publication number CN222395628U discloses a photovoltaic panel protection structure that, in severe weather, moves a protective plate to cover the photovoltaic panel, thus preventing physical damage. However, the overall structure described above is complex, making design and manufacturing difficult and increasing material, processing, and assembly costs. During protection, the protective plate blocks some or all of the sunlight from reaching the photovoltaic panel, preventing it from generating electricity and significantly reducing power generation efficiency. Because protection affects power generation, it can only protect the photovoltaic panel under specific conditions of severe weather, and cannot provide all-weather, constant protection. Utility Model Content

[0004] The purpose of this utility model is to provide a self-protecting photovoltaic module that provides all-weather protection for the photovoltaic panel, does not affect power generation, and is easy to install and remove at a low cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A self-protecting photovoltaic module includes a stand, a mounting plate, a photovoltaic panel, and a protective frame. The mounting plate is installed on the top of the stand, and the photovoltaic panel is installed on the top of the mounting plate. The protective frame includes a frame and tempered glass circumferentially connected to the frame. Ear plates are installed at the corners of the mounting plate, and fixing rods are installed at the corners of the frame. A locking rod is rotatably provided at the end of the fixing rod away from the frame. The ear plates and fixing rods correspond one-to-one, and the fixing rod passes through the corresponding ear plate. The locking rod is rotated to lock the ear plate to the bottom.

[0007] Preferably, a first magnetic attractor is embedded at the bottom of the ear plate, and a second magnetic attractor is embedded inside the locking rod. When the locking rod is rotated, the second magnetic attractor is attracted to the first magnetic attractor.

[0009] Preferably, a positioning member is installed on the top of the ear plate, and a limiting groove is formed through the positioning member along its height direction. Positioning blocks are installed at the corners of the frame, and the fixing rod is disposed through the positioning block. The positioning block is circumferentially limited to the limiting groove corresponding to the positioning member.

[0010] Preferably, a buffer ring is installed at the end of the positioning block away from the frame, and the buffer ring abuts against the top of the ear plate.

[0011] Preferably, a pivot is installed on the edge of the fixed rod away from the frame, one end of the locking rod is hinged to the pivot, and the length of the locking rod is less than the diameter of the fixed rod.

[0012] Preferably, the ear plate has a through hole extending along its height direction, and the fixing rod is inserted into the through hole.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides a self-protecting photovoltaic module, including a stand, a mounting plate, a photovoltaic panel, and a protective frame. The mounting plate is installed on top of the stand, and the photovoltaic panel is installed on top of the mounting plate. The protective frame is used to protect the photovoltaic panel in all weather conditions. The protective frame includes a frame and tempered glass connected circumferentially to the frame.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] This embodiment provides a self-protecting photovoltaic module that can protect the photovoltaic panel in all weather conditions without affecting the power generation of the photovoltaic panel. The overall structure is simple, which improves installation efficiency and reduces installation costs.

[0029] Please see Figures 1 to 4 This embodiment provides a self-protecting photovoltaic module including a support frame 1, a mounting plate 2, a photovoltaic panel 3, and a protective frame 4. The mounting plate 2 is mounted on top of the support frame 1, the photovoltaic panel 3 is mounted on top of the mounting plate 2, and the protective frame 4 provides all-weather protection for the photovoltaic panel 3.

[0030] Optionally, please refer to Figure 1 and Figure 2The support frame 1 includes a fixed pier 11, a support rod 12, and two support rods 13. The fixed pier 11 is placed on the installation platform and is relatively heavy, so it can be placed stably on the installation platform. The support rod 12 is installed on the fixed pier 11, and the back of the installation plate 2 is installed on the top of the support rod 12. One end of each of the two support rods 13 is installed on the support rod 12, and the other end is installed on both sides of the width direction of the installation plate 2, thereby stably supporting the installation plate 2.

[0031] Please continue reading. Figure 1 and Figure 2 The protective frame 4 includes a frame 41 and tempered glass 42 circumferentially connected to the frame 41. The frame 41 is installed on the top of the mounting plate 2 and is used to fix and protect the tempered glass 42, thereby enhancing the overall strength of the protective frame 4. The tempered glass 42 covers the photovoltaic panel 3. On the one hand, due to the high strength and impact resistance of the tempered glass 42 itself, it can withstand the impact of hail or flying stones in severe weather, effectively preventing damage to the photovoltaic panel 3 and extending the service life of the photovoltaic panel 3. On the other hand, light can pass through the tempered glass 42 to irradiate the photovoltaic panel 3, and the photovoltaic panel 3 can generate electricity normally.

[0032] Furthermore, the outer surface of the tempered glass 42 is covered with an anti-reflective film, which can reduce the reflection of light on the surface of the tempered glass 42, improve the light absorption rate of the photovoltaic panel 3, and thus improve the power generation efficiency of the photovoltaic panel 3.

[0033] Furthermore, a self-cleaning coating is applied to the outer surface of the anti-reflective film. This self-cleaning coating utilizes the principle of photocatalysis to decompose organic pollutants on the outer surface of the tempered glass 42 under light, making the outer surface of the tempered glass 42 super-hydrophilic. Natural forces such as rainwater can easily wash away dust and dirt from the outer surface of the tempered glass 42, reducing manual cleaning costs. This gives the tempered glass 42 a self-cleaning function, reducing the adhesion of dust and dirt to the outer surface of the tempered glass 42, lowering cleaning costs and maintenance workload, while ensuring that the photovoltaic panel 3 is always in a good light-receiving state, further improving the power generation efficiency of the photovoltaic panel 3.

[0034] In this embodiment, the protective frame 4 is detachably mounted on the mounting plate 2, facilitating assembly and disassembly. For example, please refer to... Figure 2 and Figure 3 Ear plates 5 are installed at the corners of the mounting plate 2, and fixing rods 6 are installed at the corners of the frame 41. The ear plates 5 and fixing rods 6 correspond one-to-one. The fixing rods 6 pass through the corresponding ear plates 5, and a locking rod 7 is rotatably set at the end of the fixing rod 6 away from the frame 41. Rotating the locking rod 7 locks the locking rod 7 to the bottom of the ear plate 5, thus completing the installation of the protective frame 4. When disassembling, simply rotate the locking rod 7 in the opposite direction to release the locking rod 7 from the ear plate 5, and then remove the protective frame 4.

[0035] The disassembly process of the protective frame 4 is simple and easy to operate, requiring no tools or professional personnel, which greatly improves installation efficiency and reduces installation costs. The installation structure of the protective frame 4 is simple, requiring no high-precision processing equipment or complex manufacturing processes, resulting in low production costs. The ear plates 5, fixing rods 6, locking rods 7, etc., are made of metal or plastic materials, which can ensure the installation strength of the protective frame 4 while keeping material costs low, thus reducing installation costs.

[0036] In this embodiment, a through hole 50 is opened through the ear plate 5 along its height direction, and the fixing rod 6 is inserted into the through hole 50. Preferably, the outer wall of the fixing rod 6 abuts against the hole wall of the through hole 50 in the circumferential direction to prevent the fixing rod 6 from shaking in the through hole 50 and improve the stability of the protective frame 4.

[0037] Furthermore, a pivot b is installed at the end of the fixing rod 6 away from the frame 41. One end of the locking rod 7 is hinged to the pivot b. When the locking rod 7 is rotated, the other end of the locking rod 7 is attached to the bottom of the ear plate 5 so as to lock the locking rod 7 to the bottom of the ear plate 5. When the locking rod 7 is rotated in the opposite direction, the top of the locking rod 7 is attached to the end of the fixing rod 6 so as to remove the fixing rod 6 from the through hole 50.

[0038] Specifically, the rotating shaft b is installed at the edge of the end of the fixed rod 6, and the length of the locking rod 7 is less than the diameter of the fixed rod 6 to prevent the locking rod 7 from interfering with the removal of the fixed rod 6 from the through hole 50.

[0039] Further, please refer to Figure 3 and Figure 4 A first magnetic suction element 51 is embedded at the bottom of the ear plate 5, and a second magnetic suction element 71 is embedded inside the locking rod 7. When the locking rod 7 is rotated, the other end of the locking rod 7 is attached to the bottom of the ear plate 5, and the second magnetic suction element 71 and the first magnetic suction element 51 attract and adhere to each other, realizing the magnetic connection between the locking rod 7 and the ear plate 5, locking the locking rod 7 to the ear plate 5, preventing the locking rod 7 from rotating on its own during use, preventing the fixing rod 6 from coming out of the through hole 50, and enhancing the fixing effect of the protective frame 4. At the same time, the locking rod 7 and the ear plate 5 can be locked and unlocked by rotation. The operation is simple, without additional tools and complicated operating steps, improving the loading and unloading efficiency of the protective frame 4.

[0040] Preferably, the second magnetic member 71 is embedded in the end of the locking rod 7 away from the rotating shaft b, thereby locking the end of the locking rod 7 away from the rotating shaft b to the bottom of the ear plate 5, effectively preventing the locking rod 7 from rotating on its own around the axis of the rotating shaft b during use.

[0041] In other feasible embodiments, a fixing post c can be installed at the end of the fixing rod 6 away from the frame 41. The fixing post c can be inserted into the through hole 50, and the rotating shaft b is installed at the end of the fixing post c.

[0042] Please continue reading. Figure 3 and Figure 4 In this embodiment, a U-shaped component 8 is installed on the top of the ear plate 5, and the bottom of the U-shaped component 8 is installed on the top of the ear plate 5. Further, positioning blocks 9 are installed at the corners of the frame 41, and fixing rods 6 are inserted through the positioning blocks 9. Each positioning block 9 corresponds to one of the U-shaped components 8. The outer wall of the positioning block 9 circumferentially abuts against the wall of the U-shaped groove formed by the corresponding U-shaped component 8. The positioning block 9 is positioned by the U-shaped component 8, initially defining the installation position of the frame 41, allowing the positioning block 9 to be more accurately aligned with the corresponding ear plate 5, facilitating subsequent fixing operations and improving the accuracy and efficiency of installation. Preferably, the opening of the U-shaped groove formed by the U-shaped component 8 faces the photovoltaic panel 3, thereby preventing the positioning block 9 from detaching from the opening of the U-shaped groove and improving the stability of the frame 41.

[0043] In other feasible embodiments, a positioning element can be installed on the top of the ear plate 5, and a limiting groove can be opened through the positioning element along its height direction. Furthermore, positioning blocks 9 are installed at the corners of the frame 41, and fixing rods 6 are inserted through the positioning blocks 9. The positioning blocks 9 correspond one-to-one with the positioning elements, and the positioning blocks 9 are circumferentially limited in the limiting grooves of the corresponding positioning elements. By initially limiting the installation position of the frame 41, the positioning blocks 9 can be more accurately aligned with the corresponding ear plates 5.

[0044] For further information, please refer to [link / reference]. Figure 4 Install a buffer ring a at the end of the positioning block 9 away from the frame 41, insert the fixing rod 6 into the through hole 50, and lock the locking rod 7 to the ear plate 5. The buffer ring a circumferentially abuts against the top of the ear plate 5. During use, the buffer ring a plays a buffering role, reducing the mutual impact between the frame 41 and the mounting plate 2 caused by vibration or external force.

[0045] The installation process of a self-protective photovoltaic module provided in this embodiment includes:

[0046] Place the protective frame 4 above the photovoltaic panel 3. The positioning block 9 installed at the corner of the frame 41 corresponds one-to-one with the ear plate 5 installed at the corner of the mounting plate 2. Control the outer wall of the positioning block 9 to abut against the groove wall of the U-shaped groove formed by the corresponding U-shaped part 8 to initially limit the installation position of the protective frame 4. Then, pass the fixing rod 6 through the positioning block 9 through the through hole 50 opened in the ear plate 5. Rotate the locking rod 7 until the second magnetic suction part 71 embedded at the end of the locking rod 7 away from the rotating shaft b attracts and adheres to the first magnetic suction part 51 embedded on the bottom side of the ear plate 5, locking the locking rod 7 to the ear plate 5, and completing the installation of the protective frame 4.

[0047] The disassembly process for a self-protective photovoltaic module provided in this embodiment includes:

[0048] Rotate the locking rod 7 in the opposite direction to release the locking rod 7 from the ear plate 5 until the top of the locking rod 7 is completely in contact with the end of the fixing rod 6. Remove the fixing rod 6 from the through hole 50 and the protective frame 4 can be removed.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
