Description

A photovoltaic module support device and photovoltaic power generation equipment Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic module support device and a photovoltaic power generation equipment. Background Technology

[0002] When conducting photovoltaic power generation projects in aquatic environments such as oceans and lakes, a dedicated floating photovoltaic support system is typically laid on the water surface to effectively support and relatively fix the photovoltaic modules. This type of support structure establishes a connection with the photovoltaic modules through physical contact. Currently, two main technical approaches are used: one is the clamping block fixing method, which uses specially made metal clamps to clamp the photovoltaic module frame at multiple points, using the friction between the clamps and the support to position the module; the other is the direct fastener connection method, where standard parts such as bolts and nuts pass through pre-drilled mounting holes in the photovoltaic module frame to form a rigid connection with the support structure.

[0003] However, in actual operation, the above-mentioned connection structure has revealed significant structural reliability issues. When there are large waves in the water environment, the floating support system will experience periodic swaying motion, causing the photovoltaic modules to be subjected to continuous lateral shear forces. In particular, when the wave height exceeds the design threshold, stress concentration will occur at the contact surface between the module frame and the clamping block, which may cause the clamping block to loosen or the module frame to deform. On the other hand, when encountering external impacts such as floating object collisions or accidental contact by ships, the mounting holes of the direct connection method will be subjected to instantaneous impact loads. Since there are stress weak areas at the edge of the holes in the aluminum alloy frame material, cracks are easily propagated around the mounting holes, and in severe cases, even the hole walls may tear.

[0004] Such structural failures will directly lead to multiple adverse consequences: the relative displacement of photovoltaic modules will damage the sealing of the electrical connection system and increase the risk of water ingress into cable joints; damage to the frame structure will reduce the overall mechanical strength of the modules and create safety hazards; more seriously, repeated structural stress may accelerate hidden damage such as microcracks in the cells and aging of the encapsulation materials, significantly shortening the actual service life of photovoltaic modules in complex aquatic environments, thereby affecting the economic benefits and power generation stability of the entire floating photovoltaic power station. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a photovoltaic module support device and a photovoltaic power generation equipment.

[0006] This utility model provides the following technical solution:

[0007] A photovoltaic module support device is provided for mounting photovoltaic modules on a floating photovoltaic support frame. The photovoltaic module support device includes an upper connector, a lower connector, and an adjusting component.

[0008] The upper connector has an upper clamping portion located above the frame of the photovoltaic module; the lower connector has a lower clamping portion corresponding to the upper clamping portion located below the frame of the photovoltaic module; the end of the lower connector facing away from the upper connector is used for fixed connection with the floating photovoltaic support; the adjusting member is located between the lower clamping portion and the lower end face of the frame of the photovoltaic module, and the adjusting member has a connecting hole; the upper connector and the lower connector are fixedly connected by fasteners so that the upper connector and the lower connector together clamp and fix the frame of the photovoltaic module; the adjusting member is fixedly connected to the frame of the photovoltaic module by fasteners passing through the connecting hole and the preset hole on the frame.

[0009] As a further improvement to the above technical solution, the upper connector is provided with a first support plate at the end opposite to the lower connector, the lower plane of the first support plate being parallel to the upper end face of the frame to form the upper clamping part; the lower connector is provided with a second support plate, the upper plane of the second support plate being parallel to the lower end face of the frame to form the lower clamping part.

[0010] As a further improvement to the above technical solution, the second support plate is provided with a limiting platform corresponding to the inner edge surface of the frame, and the limiting platform is disposed on the end of the second support plate near the middle of the photovoltaic module.

[0011] As a further improvement to the above technical solution, the end face of the limiting platform near the inner edge surface is provided with an elastic pad.

[0012] As a further improvement to the above technical solution, the adjusting member is specifically plate-shaped and located between the lower end face of the frame and the second support plate, and the end face area of ​​the adjusting member is larger than the upper support surface area of ​​the second support plate.

[0013] As a further improvement to the above technical solution, the upper connector is provided with a boss at the end near the lower connector, and the adjusting member is also located between the boss and the lower connector.

[0014] As a further improvement to the above technical solution, the adjusting element is specifically made of an elastic material.

[0015] As a further improvement to the above technical solution, the connecting hole is an elongated hole, and the extending direction of the connecting hole is perpendicular to the edge line of the clamped frame.

[0016] As a further improvement to the above technical solution, multiple connection holes are provided along the edge line of the frame.

[0017] This utility model also provides a photovoltaic power generation device, including a photovoltaic module support device as described in any of the above.

[0018] Compared with related technologies, the beneficial effects of this utility model are:

[0019] The photovoltaic module support device provided by this utility model has a reasonable installation process and is easy to operate, which can effectively improve the assembly efficiency and quality of photovoltaic modules and floating photovoltaic brackets.

[0020] During installation, multiple photovoltaic module support devices are first moved smoothly and accurately to the vicinity of the frame of the two opposite longer sides of the photovoltaic module.

[0021] Next, the initial positioning of the connectors and the frame is performed. The installer positions the upper clamping part of the upper connector above the frame, while ensuring the lower clamping part of the lower connector is below the frame. At this point, the upper and lower clamping parts form a preliminary vertical alignment with the frame, but a tight connection is not yet established. This step provides the basic framework for the subsequent installation of adjustment components and fasteners. The installer must carefully adjust the position of the connectors to ensure their relative position to the frame is accurate.

[0022] Next, the adjusting component is inserted between the frame and the lower clamping part. The adjusting component plays a crucial role in this installation process; it not only serves as a connector but also allows for adjustment according to different photovoltaic module specifications. Installers need to slowly and meticulously adjust the relative position of the adjusting component and the frame, ensuring that the connecting holes of the adjusting component are aligned with the pre-drilled holes on the frame through visual inspection or with the aid of professional measuring tools. Once adjusted, appropriate fasteners are used to securely connect the connecting holes of the adjusting component to the pre-drilled holes on the frame. The selection of fasteners should be determined based on actual needs and the installation environment to ensure a firm and reliable connection.

[0023] After securing the adjustment component to the frame, the next step is to secure the upper and lower connectors. Installers use fasteners to firmly connect the upper and lower connectors. As the fasteners are tightened, the upper and lower connectors gradually move closer to the frame, ultimately clamping and securing the photovoltaic module's frame and adjustment component. This clamping method effectively secures the photovoltaic module to the support device, preventing loosening or displacement during subsequent use. Installers must tighten the fasteners to the specified torque value to ensure the connection strength meets requirements.

[0024] Finally, connect the lower connector to the floating photovoltaic support. This step marks the completion of the entire assembly of the photovoltaic modules and the floating photovoltaic support. Installers must ensure that the connection is secure to prevent loosening during use. The entire installation process is simple and efficient, with each step closely linked, which can greatly shorten installation time and improve installation efficiency.

[0025] It is worth mentioning that this support device exhibits strong adaptability through the movable cooperation between the adjusting component and the lower connecting component before fixed clamping. In practical applications, the spacing of the pre-drilled holes on the frames of photovoltaic modules produced by different manufacturers may vary. The photovoltaic module support device of this invention can adapt to photovoltaic modules with different pre-drilled hole spacings by adjusting the position of the adjusting component. Installers do not need to customize support devices for different specifications of photovoltaic modules; they can complete the installation simply by adjusting the adjusting component. This not only improves installation efficiency but also reduces installation costs.

[0026] After installation, the photovoltaic (PV) modules enter the usage phase. Due to the tight clamping fit between the upper connector, lower connector, adjusting components, and frame, this close fit provides significant friction. This friction plays a crucial role in the operation of the PV modules. It effectively limits the relative displacement between the PV modules and the floating PV support, preventing the PV modules from swaying or shifting on the support due to external factors (such as wind, waves, and water currents), thus ensuring the normal power generation efficiency of the PV modules. Simultaneously, this friction also limits the relative displacement between the adjusting components and the frame, avoiding excessive shearing forces generated by their relative movement. Excessive shearing forces may damage the pre-drilled holes on the frame caused by the fasteners, affecting the installation stability and lifespan of the PV modules.

[0027] Furthermore, the fixed connection between the adjusting component and the frame further increases the friction between the upper and lower connecting components and the frame when there is a tendency for the photovoltaic module to slide relative to it. When the photovoltaic module is subjected to external forces and tends to slide relative to the support device, the fixed connection between the adjusting component and the frame makes the entire connection system more stable, thereby increasing the friction between the upper and lower connecting components and the frame. This enhanced friction makes the assembly between the photovoltaic module and the floating photovoltaic bracket more reliable, ensuring the stability and safety of the photovoltaic module even under harsh environmental conditions, and improving the operating efficiency and reliability of the entire photovoltaic power generation system.

[0041] Example 1

[0042] As shown in Figures 1 and 2, an embodiment of the present invention provides a photovoltaic module support device for mounting a photovoltaic module 100 on a floating photovoltaic support. The photovoltaic module support device includes an upper connector 200, a lower connector 300, and an adjusting member 400.

[0043] The upper connector 200 has an upper clamping portion located above the frame 110 of the photovoltaic module 100; the lower connector 300 has a lower clamping portion corresponding to the upper clamping portion located below the frame 110 of the photovoltaic module 100; the end of the lower connector 300 facing away from the upper connector 200 is used for fixed connection with the floating photovoltaic support; the adjusting member 400 is located between the lower clamping portion and the lower end face of the frame 110 of the photovoltaic module 100, and the adjusting member 400 has an upper clamping portion located above the frame 110 of the photovoltaic module 100. A connection hole 410 is provided; the upper connector 200 and the lower connector 300 are fixedly connected by a fastener 420, so that the upper connector 200 and the lower connector 300 together clamp and fix the frame 110 of the photovoltaic module 100; the adjusting member 400 is fixedly connected to the frame 110 of the photovoltaic module 100 by a fastener 420 passing through the connection hole 410 and a preset hole on the frame 110; the fastener 420 may be a bolt, a buckle or other structure depending on the application scenario.

[0044] In this embodiment, the photovoltaic module support device is first moved smoothly and accurately to the vicinity of the frame 110 of the two opposite longer sides of the photovoltaic module 100 during the installation process.

[0045] Next, preliminary positioning of the connectors and frame 110 is performed. The installer positions the upper clamping part of the upper connector 200 above the frame 110, while ensuring the lower clamping part of the lower connector 300 is below the frame 110. At this point, the upper and lower clamping parts form a preliminary vertical correspondence with the frame 110, but a tight connection is not yet established. This step provides the basic framework for the subsequent installation of the adjusting part 400 and fastener 420. The installer must carefully adjust the position of the connectors to ensure their relative position to the frame 110 is accurate.

[0046] Subsequently, the adjusting component 400 is inserted between the frame 110 and the lower clamping part. The adjusting component 400 plays a crucial role in this installation process, serving not only as a connector but also allowing adjustment according to different photovoltaic module 100 specifications. Installers need to adjust the relative position of the adjusting component 400 and the frame 110, ensuring, by visual inspection or with the aid of professional measuring tools, that the connecting hole 410 of the adjusting component 400 aligns with the pre-drilled hole on the frame 110. Once adjusted, suitable fasteners 420 are used to securely connect the connecting hole 410 of the adjusting component 400 to the pre-drilled hole on the frame 110. The selection of fasteners 420 should be determined based on actual needs and the installation environment to ensure a firm and reliable connection.

[0047] After the adjusting component 400 is fixedly connected to the frame 110, the next step is to fix the upper connecting component 200 and the lower connecting component 300. The installer uses fasteners 420 to fix the upper connecting component 200 and the lower connecting component 300. During the tightening of the fasteners 420, the upper connecting component 200 and the lower connecting component 300 gradually move closer to the frame 110, ultimately clamping and fixing the frame 110 of the photovoltaic module 100 and the adjusting component 400. This clamping and fixing method effectively fixes the photovoltaic module 100 to the support device, preventing loosening or displacement during subsequent use. The installer must tighten the fasteners 420 according to the specified torque value to ensure that the connection strength meets the requirements.

[0048] Finally, connect the lower connector 300 to the floating photovoltaic support. This step marks the completion of the assembly of the entire photovoltaic module 100 and the floating photovoltaic support. Installers must ensure the connection is secure to prevent loosening during use. The entire installation process is simple and efficient, with each step closely linked, significantly reducing installation time and improving efficiency.

[0049] It is worth mentioning that the support device exhibits strong adaptability through the movable cooperation between the adjusting member 400 and the lower connecting member 300 before fixed clamping. In practical applications, the hole spacing of the reserved holes on the frame 110 of photovoltaic modules 100 produced by different manufacturers may vary. However, the photovoltaic module support device of this embodiment can adapt to photovoltaic modules 100 with different reserved hole spacings by adjusting the position of the adjusting member 400. Installers do not need to customize support devices for photovoltaic modules 100 of different specifications; they can complete the installation simply by adjusting the adjusting member 400. This not only improves installation efficiency but also reduces installation costs.

[0050] After installation, the photovoltaic module 100 enters the usage stage. Due to the tight clamping fit between the upper connector 200, lower connector 300, adjusting member 400, and frame 110, this close fit provides significant friction. This friction plays a crucial role in the use of the photovoltaic module 100. It effectively limits the relative displacement between the photovoltaic module 100 and the floating photovoltaic support, preventing the photovoltaic module 100 from swaying or shifting on the support due to external factors (such as wind, waves, and water currents), thus ensuring the normal power generation efficiency of the photovoltaic module 100. Simultaneously, this friction also limits the relative displacement between the adjusting member 400 and the frame 110, avoiding excessive shearing force generated by their relative movement. Excessive shearing force may damage the pre-drilled holes on the frame 110 caused by the fastener 420, affecting the installation stability and service life of the photovoltaic module 100.

[0051] Furthermore, the fixed connection between the adjusting member 400 and the frame 110 further increases the friction between the upper connecting member 200 and the lower connecting member 300 and the frame 110 when the upper connecting member 200 and the lower connecting member 300 tend to slide relative to the photovoltaic module 100. When the photovoltaic module 100 is subjected to external forces and tends to slide relative to the support device, the fixed connection between the adjusting member 400 and the frame 110 makes the entire connection system more stable, thereby increasing the friction between the upper and lower connecting members 300 and the frame 110. This enhanced friction makes the assembly between the photovoltaic module 100 and the floating photovoltaic bracket more reliable, ensuring the stability and safety of the photovoltaic module 100 even under harsh environmental conditions, and improving the operating efficiency and reliability of the entire photovoltaic power generation system.

[0052] As shown in Figure 3, in some specific embodiments, the upper connector 200 is positioned away from the end of the lower connector 300, and a first support plate 210 is carefully provided. During the design process, the positional relationship between the first support plate 210 and the frame 110 was precisely planned to ensure that the lower plane of the first support plate 210 is parallel to the upper surface of the frame 110. This parallel arrangement allows the first support plate 210 to fit tightly against the upper surface of the frame 110, thereby forming the upper clamping portion.

[0053] Meanwhile, a corresponding structural design was also implemented on the lower connector 300, including a second support plate 310. Similarly, the positions of the second support plate 310 and the frame 110 were carefully arranged to ensure that the upper surface of the second support plate 310 is parallel to the lower end surface of the frame 110. This parallel arrangement allows the upper surface of the second support plate 310 to make good contact with the lower end surface of the frame 110, thereby forming the lower clamping portion.

[0054] The design of the upper and lower clamping portions as plate-like structures offers significant advantages. In actual clamping operations, the plate-like upper and lower clamping portions can achieve a larger contact area with the frame 110. Compared to clamping structures of other shapes, the plate-like structure effectively increases the clamping area with the frame 110. When the same clamping force is applied, the increased contact area reduces the pressure per unit area. This significantly reduces the probability of damage to the frame 110 due to excessive clamping force. During the long-term use of the photovoltaic module support device, the frame 110, as a crucial load-bearing component, is vital to the stability and reliability of the entire device. This plate-like clamping design better protects the frame 110, thereby ensuring high reliability of the photovoltaic module support device in practical applications and meeting the needs of various complex environments.

[0055] In some specific embodiments, the second support plate 310 is provided with a limiting platform 311 corresponding to the inner edge surface 111 of the frame 110. The limiting platform 311 is disposed on the end of the second support plate 310 near the middle of the photovoltaic module 100, and is used to limit the relative position of the frame 110 and this embodiment. In actual application, the photovoltaic module 100 may be affected by various external factors, such as strong winds, water flow impacts, vibrations, etc. When the photovoltaic module 100 is affected by these external factors, the frame 110 tends to move away from this embodiment (i.e., the photovoltaic module support device). At this time, the limiting platform 311 plays a key role. Since the limiting platform 311 corresponds to the inner edge surface 111 of the frame 110, when the frame 110 tends to move, the limiting platform 311 will abut against the inner edge surface 111 of the frame 110, thereby limiting the relative position of the frame 110 and this embodiment and preventing the frame 110 from moving further.

[0056] This limiting design greatly improves the assembly reliability of this embodiment. It ensures that the photovoltaic module 100 can be stably fixed on the support device in various complex environments, and will not loosen or shift due to external factors, thereby guaranteeing the normal operation and service life of the photovoltaic module 100, and also improving the stability and safety of the entire photovoltaic power generation system.

[0057] In some specific embodiments, the limiting platform 311 is provided with an elastic pad 312 near the end face of the inner edge surface 111. The elastic pad 312 is reliably made of rubber. In actual assembly and use scenarios, the limiting platform 311 plays an important role in limiting and blocking the frame 110 to prevent improper displacement of the frame 110 due to external factors. However, when the limiting platform 311 directly contacts the frame 110 and performs the limiting action, the hard contact between the two may generate a large impact force, which may damage the frame 110, such as scratches or deformation. This will not only affect the aesthetics of the photovoltaic module 100, but may also reduce its structural strength and service life.

[0058] To effectively address this issue, an elastic pad 312 is added to the end face of the limiting platform 311 near its inner edge 111. The elastic pad 312 has excellent cushioning properties; when the limiting platform 311 limits and blocks the frame 110, the elastic pad 312 can elastically deform, absorbing and dispersing the impact force generated when the two come into contact. In this way, while achieving the limiting function, the probability of damage to the frame 110 is greatly reduced, ensuring the integrity and stability of the frame 110, and thus guaranteeing the assembly quality and reliability of the entire photovoltaic module support device.

[0059] In some specific embodiments, the adjusting member 400 is specifically plate-shaped and located between the lower end face of the frame 110 and the second support plate 310. The end face area of ​​the adjusting member 400 is larger than the upper support surface area of ​​the second support plate 310, so as to further increase the clamping surface area of ​​the second support plate 310 on the frame 110.

[0060] In some specific embodiments, the upper connector 200 has a boss 220 at its end near the lower connector 300, and the adjusting member 400 is located between the boss 220 and the lower connector 300. Specifically, when the upper connector 200 and the lower connector 300 are connected and brought closer together, the boss 220 begins to play a crucial role. As the upper connector 200 moves closer to the lower connector 300, the boss 220 first abuts against the adjusting member 400. At this time, the contact between the boss 220 and the adjusting member 400 lays the foundation for the subsequent clamping action. Then, as the upper connector 200 continues to move, the boss 220 further presses the adjusting member 400 against the lower connector 300. During this process, the pressure applied to the adjusting member 400 by the boss 220 is transmitted to the lower connector 300 through the adjusting member 400, forming a tight clamping force. This clamping force can further improve the clamping effect of the upper connector 200 and the lower connector 300 on the adjusting member 400, ensuring that the adjusting member 400 is stably fixed between the two and will not loosen or shift.

[0061] In some specific embodiments, the adjusting member 400 is made of an elastic material, such as rubber. During the assembly of the photovoltaic module support device, fasteners 420 are used to fix the upper connecting member 200 and the lower connecting member 300, thereby clamping and fixing the frame 110 of the photovoltaic module 100. However, in actual operation, it is difficult to precisely control the clamping force applied by the fasteners 420 between the upper connecting member 200 and the lower connecting member 300. If the clamping force is too large, it will exert excessive pressure on the frame 110, leading to deformation of the frame 110. Deformation of the frame 110 will not only affect the appearance of the photovoltaic module 100, but may also damage its structural strength and electrical performance, reducing the service life and power generation efficiency of the photovoltaic module 100.

[0062] Designing the adjusting component 400 as an elastic material effectively solves this problem. When the clamping force applied by the fastener 420 between the upper connector 200 and the lower connector 300 is excessive, the elastic adjusting component 400 will deform. This deformation is not meaningless but can partially absorb the excessive clamping force. Through deformation, the adjusting component 400 buffers and disperses the excessive pressure that was originally applied directly to the frame 110, thereby reducing the pressure on the frame 110 to a certain extent. In this way, the probability of the frame 110 being squeezed and deformed is greatly reduced, ensuring the stability and integrity of the frame 110 in the support device, and thus ensuring the normal operation and performance of the photovoltaic module 100.

[0063] As shown in Figure 4, in some specific embodiments, the connecting hole 410 is an elongated hole, and the extending direction of the connecting hole 410 is perpendicular to the edge line of the clamped frame 110. In the actual assembly process of the photovoltaic module support device, different models of photovoltaic modules 100 are often encountered, and the positions of the reserved holes on the frame 110 of these different models of photovoltaic modules 100 may not be completely consistent. If the connecting hole 410 adopts a traditional circular hole design, once the position of the reserved hole deviates, it may cause the connecting hole 410 to fail to accurately align with the reserved hole, thereby affecting the assembly efficiency and stability of the entire device.

[0064] Designing the connecting hole 410 as an elongated hole, with its extension direction perpendicular to the edge of the frame 110, provides the adjusting component 400 with greater adjustment space. When assembling different models of photovoltaic modules 100, the adjusting component 400 can make small-amplitude adjustments to the pre-drilled holes on different frames 110. During the fine-tuning process, the adjusting component 400 can slide along the extension direction of the elongated hole, allowing the position of the connecting hole 410 to adapt to the position of the pre-drilled hole, thereby achieving docking and connection between the connecting hole 410 and the pre-drilled hole. This design greatly improves the versatility and adaptability of the photovoltaic module support device, reduces the need to replace the support device or make complex modifications due to different photovoltaic module 100 models, reduces assembly costs and time costs, and improves the construction efficiency of the entire photovoltaic power generation system.

[0065] In some specific embodiments, multiple connection holes 410 are provided along the edge line of the frame 110. In actual photovoltaic module 100 application scenarios, the spacing of the reserved holes on the frame 110 of photovoltaic modules 100 produced by different manufacturers, or even different series of products from the same manufacturer, may vary significantly. If the number of connection holes 410 on the support device is limited and their positions are fixed, when encountering photovoltaic modules 100 with excessively large differences in the spacing of reserved holes, the connection holes 410 and the reserved holes may not be precisely aligned, resulting in the inability to install normally and thus limiting the scope of use of the support device.

[0066] In this embodiment, this problem is cleverly solved by providing multiple connection holes 410 along the edge of the frame 110. When installation is required according to the spacing of the reserved holes on the frame 110 of different photovoltaic modules 100, the installer can flexibly select the corresponding connection holes 410 for connection. For example, when the spacing of the reserved holes is small, the adjacent connection holes 410 can be selected for fixing; when the spacing of the reserved holes is large, a combination of connection holes 410 with appropriate positions and larger spacing can be selected to complete the connection. This design allows the support device to adapt to more types of photovoltaic modules 100, further improving the applicability of this embodiment, reducing the installation difficulties and cost increases caused by the mismatch of photovoltaic module 100 specifications, and providing convenience for the construction and maintenance of photovoltaic power generation systems.
