Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a pressure block structure for photovoltaic module installation. Background Technology

[0002] During the installation of photovoltaic (PV) modules, the edges of the modules are easily bumped and damaged, which can affect the efficiency of the PV modules during operation. Traditional PV module mounting blocks are insufficient to protect the perimeter of the PV modules, reducing the effectiveness of fixing and protecting the PV modules. Traditional PV module mounting blocks are usually fixed with bolts, but the mounting blocks are often located in outdoor environments, which can easily lead to rust at the ends of the bolts. This makes it difficult for operators to disassemble and repair the modules, affecting the efficiency of the subsequent equipment operation.

[0003] Chinese Patent Publication No. CN115864985A, Publication Date: March 28, 2023, discloses a Chinese patent entitled "A Self-Locking Wedge-Shaped Photovoltaic Mid-Pressure Block" for connecting a first photovoltaic module and a second photovoltaic module. It includes a U-shaped pressure plate located between the first and second photovoltaic modules, and further comprises: a wedge-shaped shaft penetrating the bottom surface of the U-shaped pressure plate and moving axially therein; a wedge-shaped block penetrating the side wall of the U-shaped pressure plate and abutting against the wedge-shaped shaft, with the wedge surface on the block engaging with the wedge surface on the shaft to compress the shaft to move axially; a latching block located at the end of the wedge-shaped shaft away from the wedge-shaped block and extending towards the slot of the second photovoltaic module to insert into and engage with it; and an elastic element sleeved on the outer periphery of the wedge-shaped shaft to provide elastic force to overcome the compression of the wedge-shaped block. This pressure block fails to protect the four corners of the photovoltaic module, resulting in poor protection. Utility Model Content

[0004] This utility model provides a pressure block structure for installing photovoltaic modules. By setting up protective plates, the four outer corners of the photovoltaic modules are protected, reducing the possibility of accidental damage to the photovoltaic modules.

[0005] A further objective of this invention is to isolate the end of the fastener from the outdoor environment by setting a sealing block, thereby reducing the corrosion of the end of the fastener.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure block structure for photovoltaic module installation, including a slider, the slider being fixed in the guide rail by a fixing member, pressure plates being provided on both sides of the top of the slider, and a telescopic plate being provided inside the outer end of the pressure plate; a guard plate being vertically provided on the lower surface of the outer end of the pressure block, and an anti-slip pad being provided on the inner side wall of the guard plate and fitting against the corner side wall of the photovoltaic module; a rotating plate being rotatably provided on the upper surface of the slider, and a sealing block being provided at the bottom end of the rotating plate, the sealing block being set in the mounting hole on the upper surface of the slider.

[0007] Preferably, the bottom end of the slider is convex and is positioned within the guide groove of the guide rail, with the slider shape matching the inner wall of the guide groove. The guide groove is convex and slightly larger than the slider. Through the cooperation between the guide rail and the slider, both ends of the slider are in contact with the inner wall of the guide groove, improving the slider's pressure-bearing capacity and reducing the possibility of the slider falling off due to unexpected situations.

[0008] Preferably, the guide groove has several fixing holes, through which the fixing component passes to fix the slider to the guide rail, and the end of the fixing component is located below the mounting hole. The annular sealing block isolates the end of the fixing component from the outdoor environment, reducing corrosion of the fixing component end.

[0009] Preferably, the protective plate is L-shaped, with its inner wall facing the photovoltaic module, and the pressure plate abuts against the upper surface of the photovoltaic module. The pressure plate fixes the photovoltaic module, and the protective plate protects the four corners of the photovoltaic module.

[0010] Preferably, the outer end face of the pressure plate is provided with a groove, and the pressure plate is slidably disposed in the groove, which is provided with a movable block. The groove is convex, and the movable block is disposed in the upper half of the groove. The upper half of the groove is smaller in size, and the shape of the movable block matches the upper half of the groove, ensuring that it can move within the groove without wobbling from side to side.

[0011] Preferably, the lower surface of the moving block and the upper surface of the inner end of the telescopic plate are fixedly connected, and the outer end face of the moving block and the inner wall of the outer end of the pressure block are connected by a return spring. One end of the return spring is fixed to the outer end face of the moving block, and the other end is fixed to the inner wall of the slide groove. Through the cooperation of the return spring and the moving block, the end of the moving block is squeezed by the return spring, so that the end of the telescopic plate, i.e., the protective plate, is in close contact with the outer wall of the photovoltaic module, thereby improving the protective effect of the telescopic plate on the photovoltaic module. The anti-slip pad is made of rubber. Through the cooperation of the telescopic plate and the anti-slip pad, the end of the telescopic plate, i.e., the protective plate, is adapted to the outer wall of the photovoltaic module 2, preventing damage to the outer wall of the photovoltaic module due to accidental situations, which could lead to malfunctions during operation of the photovoltaic module equipment, affect the stability of subsequent equipment operation, and reduce the possibility of accidental slippage of the telescopic plate.

[0012] Preferably, the sealing block is cylindrical, and the outer circumferential surface of the sealing block is provided with several annular sealing rings.

[0013] Preferably, the inner wall of the mounting hole is provided with several annular grooves, which fit into the annular sealing rings. These annular sealing rings are linearly arranged on the outer wall of the sealing block. Through the cooperation of the rotating plate and the fixed shaft, the operator can easily rotate the rotating plate on the outer wall of the fixed shaft, facilitating the installation and rotation of the bolts. By sliding the rotating plate on the outer wall of the fixed shaft, the annular sealing rings extend into the mounting hole, reducing the risk of rust at the bolt ends and facilitating subsequent replacement and maintenance of the equipment.

[0014] Preferably, the upper surface of the slider is provided with a fixed shaft, and the rotating plate is rotatably connected to the fixed shaft.

[0015] Preferably, the fixing component is a bolt and nut, and the slider has an operating cavity below the mounting hole, with the bolt end positioned inside the operating cavity. The nut and bolt are connected by threads, and the nut moves axially on the bolt. The slider and nut are in contact with the guide rail to limit the movement of the limiting component.

[0016] Beneficial effects: This utility model, by setting up a telescopic plate, moves the telescopic plate to drive the moving block to move, and the moving block squeezes the reset spring, so that the inside of the telescopic plate is connected to the outer wall of the photovoltaic module through the anti-slip pad, reducing the possibility of accidental damage to the photovoltaic module and ensuring the stability of the equipment during operation.

[0017] This utility model incorporates a sealing block, allowing operators to easily install and secure bolts by rotating a rotating plate on a fixed shaft. The rotating plate connects the sealing block to the mounting hole, linking the annular sealing ring to the annular groove, thus reducing bolt end corrosion and facilitating subsequent replacement and maintenance of certain equipment.

[0023] The photovoltaic module installation pressure block structure provided by this utility model focuses on the protection and fixation reliability issues in the photovoltaic module installation process. Through the precise cooperation between the slider 3 and the guide rail 1, the targeted protection of the L-shaped guard plate, and the anti-corrosion design of the sealing block 8, an installation solution that takes into account the fixation stability, module protection, and convenience of later maintenance is constructed.

[0024] exist Figure 1 and Figure 2In the illustrated embodiment, the pressure block structure uses the slider 3 as the core load-bearing component, forming a stable connection with the guide rail 1 through fixing parts, thereby achieving precise fixing and comprehensive protection of the photovoltaic module 2. Pressure plates 4 are symmetrically arranged on both sides of the top of the slider 3. A sliding telescopic plate 5 is built into the outer end of the pressure plate 4. A protective plate extends vertically from the lower surface of the outer end of the telescopic plate 5. The anti-slip pads 10 on the inner sidewall of the protective plate tightly fit against the corner sidewall of the photovoltaic module 2, forming a wrap-around protection for the four corners of the module. A rotating plate 7 is rotatably connected to the upper surface of the slider 3 via a fixed shaft 6. The sealing block 8 at the bottom of the rotating plate 7 can be embedded in the mounting hole of the slider 3, isolating the end of the fixing parts from the outdoor environment and effectively preventing corrosion. The overall structure is compact, and the components work together to ensure the firmness of the photovoltaic module 2 installation and achieve dual protection for both the module and the fixing parts, making it suitable for various outdoor photovoltaic power station installation scenarios.

[0025] exist Figure 1 and Figure 2 In the preferred embodiment shown, the convex fit design of the slider 3 and the guide groove of the guide rail 1 provides a solid foundation support for the entire pressure block structure. The bottom end of the slider 3 is designed to be convex, precisely matching the convex guide groove of the guide rail 1. This shape matching allows both ends of the slider 3 to fit tightly against the inner wall of the guide groove after installation, forming a comprehensive limiting constraint. Compared with the traditional planar contact sliding structure, the convex fit significantly improves the pressure-bearing capacity of the slider 3, effectively dispersing the pressure from the weight of the photovoltaic module 2 itself and the outdoor environment (such as wind and snow), preventing the slider 3 from deforming or breaking due to excessive local stress. The guide groove is designed to be slightly larger than the slider 3, which facilitates precise alignment during installation and provides buffer space when thermal expansion and contraction occur due to temperature changes, preventing damage caused by mutual squeezing between components. At the same time, the convex structure effectively restricts the horizontal displacement of the slider 3, significantly reducing the risk of the slider 3 falling off the guide rail 1 due to accidental collisions or long-term vibration, ensuring the overall stability of the photovoltaic module 2 after installation, and providing a reliable guarantee for the long-term safe operation of the photovoltaic system.

[0026] exist Figure 1 and 4In the preferred embodiment shown, the fixing holes in the guide groove cooperate with the fixing component, further enhancing the connection reliability between the slider 3 and the guide rail 1. The evenly distributed fixing holes in the guide groove provide multiple installation options for the fixing component. Operators can flexibly adjust the fixing position of the slider 3 on the guide rail 1 according to the actual installation spacing of the photovoltaic module 2, significantly improving the adaptability of the pressure block structure. The fixing component passes through the fixing holes to firmly fix the slider 3 to the guide rail 1, forming a double locking structure of "convex fit + bolt 12 fixation," completely preventing axial or lateral displacement of the slider 3 on the guide rail 1. The end of the fixing component is located below the mounting hole, reserving space for the subsequent installation of the sealing block 8. When the sealing block 8 is embedded in the mounting hole, it can completely seal the end of the fixing component, effectively isolating it from outdoor rainwater, moisture, dust, and other corrosive media, reducing corrosion at the end of the fixing component from the root cause, extending the service life of the fixing component, reducing safety hazards caused by fixing component failure, and reducing the frequency and cost of subsequent maintenance and replacement of the fixing component.

[0027] exist Figure 2 and Figure 3 In the preferred embodiment shown, the collaborative design of the L-shaped protective plate and the pressure plate 4 achieves the dual functions of fixing and protecting the photovoltaic module 2. The protective plate adopts an L-shaped structure, with its inner wall facing the photovoltaic module 2, which can precisely fit the corner position of the photovoltaic module 2, providing wrap-around protection for the four corners of the module from two vertical directions. The four corners of the photovoltaic module 2 are structurally weak areas, which are easily damaged by collisions and friction during transportation, installation, or use. The L-shaped protective plate can effectively block external impact forces and prevent corner cracks or chipping. The pressure plate 4 abuts tightly against the upper surface of the photovoltaic module 2, and firmly fixes the photovoltaic module 2 to the slider 3 through downward pressure, preventing the module from moving up and down; the protective plate restricts the horizontal displacement of the module from the side. The two form a dual fixing mode of "top pressure + side protection", which further improves the stability of the photovoltaic module 2 installation and ensures that the module always maintains the correct installation posture in harsh outdoor environments.

[0028] exist Figure 3In the preferred embodiment shown, the convex fit design of the sliding groove of the pressure plate 4 and the moving block 13 provides a stable guarantee for the flexible adjustment of the telescopic plate 5. The convex sliding groove on the outer end face of the pressure plate 4 precisely matches the shape of the moving block 13. The moving block 13 is located in the upper half of the sliding groove, and this area is relatively small, specifically, its width is smaller than the width of the lower half of the sliding groove. This ensures that the moving block 13 moves smoothly along the length of the sliding groove while effectively limiting the left and right swaying of the moving block 13, ensuring that the adjustment trajectory of the telescopic plate 5 is stable and controllable. This design avoids the problem of the protective plate not fitting tightly with the photovoltaic module 2 due to the offset of the telescopic plate 5 during the adjustment process, ensuring the consistency of the protective effect. At the same time, the structure of the convex sliding groove can prevent the moving block 13 from falling out of the sliding groove, improving the reliability of the structure. Even under long-term use or vibration, it can still maintain a good fit, laying the foundation for subsequent adaptive adjustment of the telescopic plate 5 by driving the return spring 14.

[0029] exist Figure 3 In the preferred embodiment shown, the coordinated design of the movable block 13, the return spring 14, and the anti-slip pad 10 constructs an adaptive side protection system for the photovoltaic module 2, effectively preventing damage to the module's corners. The lower surface of the movable block 13 is firmly fixed to the upper surface of the inner end of the telescopic plate 5, forming a synchronous linkage structure. The outer end face of the movable block 13 is connected to the inner wall of the slide groove through the return spring 14. The return spring 14 is always in a compressed state, continuously applying inward squeezing force to the movable block 13. This elastic drive design enables the telescopic plate 5 to have adaptive adjustment capabilities: when the photovoltaic module 2 is installed in place, the elastic force of the return spring 14 pushes the movable block 13 to move inward, causing the L-shaped protective plate at the end of the telescopic plate 5 to tightly fit against the outer wall of the photovoltaic module 2. Regardless of minor deviations in the dimensions of the photovoltaic module 2 or slight deformation due to temperature changes in the outdoor environment, the protective plate can maintain a tight fit through the elastic deformation of the spring, ensuring comprehensive and stable protection. Meanwhile, the anti-slip pads 10 on the inner wall of the protective plate are made of rubber. The softness of rubber can prevent scratch damage caused by hard contact between the protective plate and the photovoltaic module 2, effectively protecting the appearance and structural integrity of the module. Its high coefficient of friction can also enhance the friction between the protective plate and the side wall of the module, preventing the telescopic plate 5 from accidentally sliding due to vibration or external force, further improving the reliability of the protection. This design fundamentally reduces the risk of equipment failure caused by damage to the corners of the module, ensuring the stability of the photovoltaic system operation, and is especially suitable for outdoor photovoltaic power stations that are exposed to complex environments such as wind and vibration for a long time.

[0030] exist Figure 4In the preferred embodiment shown, the sealing block 8 and the mounting hole form a multi-ring seal, creating a corrosion barrier for the end of the fastener and completely solving the problem of outdoor rust. The sealing block 8 is designed as a cylinder, with several annular sealing rings 9 evenly arranged along the axial direction on its outer circumference. The annular sealing rings 9 are made of elastic corrosion-resistant material, possessing good sealing performance and anti-aging ability. Correspondingly, the inner wall of the mounting hole is provided with an annular groove 15 that precisely fits the annular sealing rings 9. When the sealing block 8 is embedded in the mounting hole, the annular sealing rings 9 will simultaneously engage with the annular groove 15, forming multiple sealing defenses. This structure can effectively prevent corrosive media such as rainwater, moisture, and dust from entering the mounting hole, completely isolating the end of the fastener from the harsh outdoor environment and preventing rust and corrosion at the source. Compared with the traditional single-seal structure, the multi-ring seal design significantly improves sealing reliability. Even if some sealing rings age and wear, the remaining sealing rings can still maintain the sealing effect, ensuring that the fastener is in good working condition for a long time, extending its service life, and reducing safety hazards caused by fastener failure. Meanwhile, the fixed shaft 6 on the upper surface of the slider 3 is rotatably connected to the rotating plate 7. When installing the fastener, the operator can rotate the rotating plate 7 around the fixed shaft 6 to one side to avoid interfering with the installation of the bolt 12. After installation, simply rotate the rotating plate 7 in the opposite direction and slide it downward to make the sealing block 8 accurately embedded in the installation hole. The whole process does not require any additional tools, and the operation is convenient and efficient, ensuring the sealing effect without affecting the installation efficiency.

[0031] exist Figure 2 and Figure 4 In the preferred embodiment shown, the rotating connection structure between the fixed shaft 6 and the rotating plate 7 further enhances the flexibility and convenience of operation. The fixed shaft 6 is vertically mounted on the upper surface of the slider 3, and the rotating plate 7 is rotatably engaged with the fixed shaft 6 through a central hole, allowing it to rotate freely around the fixed shaft 6 without any jamming during rotation. This design allows operators to flexibly adjust the position of the rotating plate 7 according to actual operational needs when installing or repairing the fastener: when installing bolt 12, the rotating plate 7 is rotated to the side offset from the mounting hole, fully exposing the mounting hole and the operating cavity below, providing ample space for tool operation; after installation, rotating the rotating plate 7 aligns the sealing block 8 with the mounting hole, and pressing down completes the seal. The rotation angle of the rotating plate 7 is unrestricted, adapting to the operating habits of different operators and significantly reducing the difficulty of installation and maintenance. Simultaneously, the connection structure between the fixed shaft 6 and the rotating plate 7 has high strength, capable of withstanding long-term rotational operation and outdoor environmental corrosion, and is not prone to breakage or deformation, ensuring the long-term reliability of the opening and closing operation of the sealing block 8, providing stable structural support for the sealing protection and subsequent maintenance of the fastener.

[0032] exist Figure 4In the preferred embodiment shown, the fastener uses a combination of bolts 12 and nuts 11, and the layout design of the operating cavity ensures both the firmness of the fixation and the convenience of later maintenance. The bolts 12 and nuts 11 are connected by threads, providing excellent self-locking performance and effectively preventing loosening due to vibration, ensuring a stable connection between the slider 3 and the guide rail 1. The operating cavity provided below the mounting hole of the slider 3 provides dedicated space for the ends of the bolts 12 and the nuts 11, completely concealing the ends of the bolts 12 within the operating cavity and avoiding direct exposure to the outdoor environment, further reducing the risk of corrosion. The nuts 11 can move axially on the bolts 12. By adjusting the position of the nuts 11, the slider 3 and the nuts 11 are respectively pressed tightly against both sides of the guide rail 1, forming a clamping and limiting structure on the guide rail 1. This bidirectional clamping structure effectively prevents axial displacement of the slider 3 on the guide rail 1, improving the overall installation stability. The dimensions of the operating chamber are designed to fully accommodate tool operation needs. When disassembling or repairing the fasteners, operators can easily tighten the nut 11 by inserting the tool through the mounting hole without disassembling the entire pressure block structure, significantly reducing maintenance time and costs. Furthermore, the standardized design of the bolts 12 and nuts 11 facilitates procurement and replacement, further enhancing the practicality and economy of the pressure block structure.

[0033] The installation process of this pressure block structure is as follows: The operator places the slider 3 into the inner wall of the guide groove of the guide rail 1. The outer wall of the slider 3 slides on the inner wall of the guide groove. The slider 3 drives the two pressure plates 4 to move. By abutting the bottom of the pressure plate 4 against the side wall of the photovoltaic module 2, the operator pulls the telescopic plate 5. The telescopic plate 5 drives the moving block 13 to move. The moving block 13 squeezes the reset spring 14, so that the inner wall of the telescopic plate 5 abuts against the end of the photovoltaic module 2 through the anti-slip pad 10, reducing the possibility of damage to the ends of the photovoltaic module 2. The operator rotates bolt 12 to pass through the movable hole at the end of guide rail 1, and moves axially on bolt 12 via nut 11. The bolt 12 and nut 11 cooperate to limit the slider 3. The operator rotates annular sealing block 8 via rotating plate 7. By moving rotating plate 7, annular sealing block 8 moves annular sealing ring 9, so that annular sealing ring 9 fits into annular groove 15, protecting the end of bolt 12 and reducing the occurrence of rust at the end of bolt 12.
