[0032] Photovoltaic mounting systems are metal or alloy structures used to support and secure photovoltaic modules. They are typically installed on the ground or rooftop to ensure the modules are positioned at the proper angle to maximize solar energy absorption and conversion into electricity. Photovoltaic mounting systems are crucial for stability, safety, and power generation efficiency. The mounting structure is designed to support the weight of the modules and withstand wind pressure, and typically includes support columns, purlins, braces, and connectors.

[0033] Purlins are the lateral support materials of photovoltaic racks. They have mounting holes on their tops for securing photovoltaic modules. Purlins are available in different models and specifications, depending on the size of the photovoltaic modules and installation requirements. Generally, purlins are designed with a length appropriate to the size of the photovoltaic modules to ensure a stable placement of the modules.

[0034] PV mount bolts and gaskets are commonly used during the installation of PV modules on the mount. They are used to secure the PV modules to the mount, ensuring a tight connection and secure fixation between the modules and the mount. Currently, the bolt sizes used to tighten and secure PV modules are all fixed. Due to uneven installation levels, the gaps between PV modules are uncontrollable, resulting in the inability to install PV modules or, after installation, the gaps are too large to effectively transmit lateral forces. Existing installation methods lack width adaptability, leaving some modules unable to fit or insufficiently fill the gaps after installation, potentially leading to the possibility of PV modules shifting.

[0035] Therefore, the inventors propose a photovoltaic module fixing device to solve the problem that existing fixing parts have poor adaptability and cannot match gaps of different widths.

[0036] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0037] Figure 1 A cross-sectional view of the photovoltaic module fixing device provided in an embodiment of the present application in use; Figure 2 A top view of a component pressing block provided in an embodiment of the present application; Figure 3 A schematic diagram of the structure of the inclined plate provided in an embodiment of the present application; Figure 4A schematic diagram of the structure of the insert provided in an embodiment of the present application; Figure 5 Schematic diagram of the bolt fixing structure provided in an embodiment of the present application.

[0038] Reference Figures 1 to 5 As shown, an embodiment of the present application provides a photovoltaic module fixing device, comprising: a module pressing block 1 and a spacing adjustment member.

[0039] The component pressing block 1 is U-shaped and has a wing plate 2 at the top. The bottom of the wing plate 2 abuts against the top of the photovoltaic component 3. The component pressing block 1 is set between two photovoltaic components 3, and the bottom of the component pressing block 1 is fixed to the photovoltaic bracket 4 below the photovoltaic component 3.

[0040] Specifically, by providing the component pressing block 1 with a U-shaped structure, local constraints and pressure can be formed, so that the photovoltaic component 3 is evenly supported and fixed.

[0041] The wing plate 2 can increase the contact area with the photovoltaic module 3, press and fix the photovoltaic module 3 and the photovoltaic bracket 4, and improve the stability of the connection.

[0042] The bottom of the component pressing block 1 is fixed to the photovoltaic bracket 4 below the photovoltaic component 3, which can further enhance the stability of the structure and ensure the safe operation of the entire photovoltaic system in natural environments such as wind and sun.

[0043] The distance adjustment component includes an insert 5 and a card plate 6. The card plate 6 is arranged between the component pressing block 1 and the photovoltaic component 3. The distance between the component pressing block 1 and the photovoltaic component 3 is adjusted by embedding the insert 5 between the card plate 6 and the component pressing block 1.

[0044] Specifically, the bottom end of the clip 6 rests against the purlin, ensuring that the insert 5 and the clip 6 are tightly engaged and do not move. By combining the insert 5 and the clip 6, the spacing between photovoltaic modules 3 can be flexibly adjusted to accommodate photovoltaic modules 3 of different sizes and arrangements, thereby improving the flexibility and applicability of the system.

[0045] The spacing adjustment member fully fills the gap when inserting the insert 5 between the clamp 6 and the module pressing block 1, effectively transmitting lateral force and ensuring a stronger and more stable connection between the module pressing block 1 and the photovoltaic module 3. By transmitting lateral force, the friction between the modules is increased, preventing relative movement or loss of balance, thereby improving overall stability.

[0046] The spacing adjustment member can be installed on one or both sides of the module pressing block 1, depending on actual needs. If it is installed on one side of the module pressing block 1, the wing plate 2 on the side where the spacing adjustment member is installed can be appropriately extended to facilitate spacing adjustment without affecting the compression effect on the photovoltaic module 3.

[0047] The present application provides a photovoltaic module 3 fixing device, which can flexibly adjust the spacing between photovoltaic modules 3 by combining the use of an insert 5 and a card plate 6, fully fill the gap between photovoltaic modules 3, and adapt to photovoltaic modules 3 of different sizes and arrangements, thereby improving the flexibility and applicability of the installation while improving the overall installation stability.

[0048] In some embodiments, the above-mentioned insert 5 is a triangular insert.

[0049] Specifically, the triangular fillet is a columnar component with a triangular cross-section. During the process of being embedded between the card plate 6 and the component pressing block 1, the tip of the triangular fillet is pressed downward. By pressing the triangular fillet downward, the gap between the card plate 6 and the component pressing block 1 is adjusted, thereby making the connection tighter and more stable.

[0050] The triangle shape provides better support and rigidity, making the columnar molding more stable and reliable when connecting or supporting. The triangular molding has a simple geometry and is easy to manufacture and install.

[0051] In some embodiments, the top of the above-mentioned card plate 6 is provided with a first inclined surface 7 that matches the angle of the insert 5, and the abutting surface between the insert 5 and the first inclined surface 7 is provided with a card groove 8. The first inclined surface 7 is provided with a card strip 9. The insert 5 and the card plate 6 are fixed by the card groove 8 and the card strip 9.

[0052] Specifically, the clamping strip 9 provided on the first inclined surface 7 is a serrated protrusion, which is engaged with the clamping slot 8 to form a bite structure, thereby forming a stable connection that can withstand a certain amount of tension and pressure, making the connection more firm and reliable.

[0053] The insert 5 and the clamping plate 6 are detachably connected, which is convenient for daily maintenance and replacement without damaging the parts themselves, making repair and replacement easy.

[0054] The clamping and fixing of the slot 8 and the strip 9 can evenly distribute the load to the entire connection surface, reduce the risk of local stress concentration, and increase the stability and durability of the connection; at the same time, it avoids the strip from exiting and forming a whole, ensuring that the horizontal force can be effectively transmitted.

[0055] In some embodiments, second inclined surfaces 10 are provided at both ends of the first inclined surface 7 , and the slope of the second inclined surface 10 is smaller than that of the first inclined surface 7 .

[0056] Specifically, the first bevel 7 and the second bevel 10 form a cross surface to constrain each other, thereby preventing the molding from sliding out laterally and improving the tightness and stability of the connection. The inclination angle of the first bevel 7 matches the angle of the molding.

[0057] By providing the second inclined surface 10, the structure of the card plate 6 can be optimized to make it more compact and utilize materials more effectively. Reasonable design of the shape and angle of the inclined surface can reduce unnecessary material waste and lower material costs.

[0058] In some embodiments, a notch 11 matching the insert 5 is provided in the middle of the wing plate 2 , and the insert 5 is inserted between the clamping plate 6 and the component pressing block 1 through the notch 11 .

[0059] Specifically, by providing a notch 11 in the middle of the wing plate 2 that matches the insert 5 , a stable connection can be formed between the insert 5 and the wing plate 2 , thereby preventing loosening and falling off between the components and ensuring the stability of the overall structure.

[0060] The design of embedding the insert 5 through the notch 11 can effectively utilize space, reduce the gap between components, make the overall structure more compact, and improve the efficiency of assembly and the utilization rate of work space.

[0061] In some embodiments, the bottom of the wing plate 2 and the top of the photovoltaic module 3 are provided with matching sawtooth structures.

[0062] Specifically, the serrated structure can form multiple transverse surfaces, increase the contact points between the connecting parts, effectively disperse the load, and improve the bearing capacity and wind pressure resistance of the connection; through the coordination of the serrated structure at the bottom of the wing plate 2 and the top of the photovoltaic module 3, the contact area and friction between the wing plate 2 and the photovoltaic module 3 can be increased, thereby improving the stability of the connection and the tensile bearing capacity.

[0063] The zigzag structure can effectively reduce the risk of shaking and loosening between the wing plate 2 and the photovoltaic module 3, improve the stability and safety of the entire structure, and avoid the risk of falling off due to external vibration or impact.

[0064] In some embodiments, a fixed pressure plate 12 is provided under the above-mentioned photovoltaic bracket 4, and both the component pressure block 1 and the fixed pressure plate 12 are provided with fixing holes 13. The purlins of the photovoltaic bracket 4 are locked between the component pressure block 1 and the fixed pressure plate 12 by passing the bolts 14 through the fixing holes 13 and cooperating with the nuts 15.

[0065] Specifically, after bolts 14 are tightened with fixed platen 12, the purlins are compressed within the space formed by bolts 14, fixed platen 12, and assembly clamp 1, preventing the need for perforations in the purlins, which would weaken their cross-section and increase work load. Fixed platen 12 prevents significant deformation of the purlins during the tightening of nuts 15, thus ensuring the stability of the support structure.

[0066] The nut 15 adopts a locking nut 15 or a double nut 15. The locking nut 15 usually has a special design, such as using an elastic washer, embedded thread, etc., to increase a certain friction on the thread pair, thereby preventing the bolt 14 from loosening by itself; the double nut 15 is to install two nuts 15 on the same bolt 14, and the two nuts 15 are locked with each other to increase the tightening force and prevent the bolt 14 from loosening under the action of external force.

[0067] The anti-loosening nut 15 or the double nut 15 can effectively prevent the bolt 14 from loosening due to wind vibration, thereby improving the stability and reliability of the connection.

[0068] By securing the pressure plate 12 and the fixing holes 13 of the module pressing block 1, and by cooperating with the bolts 14 and nuts 15, a secure connection is achieved between the purlins of the photovoltaic support 4 and the module pressing block 1, preventing the support system from shifting or loosening due to external wind or other environmental factors. The use of bolts 14 and nuts 15 for securing the system makes installation and adjustment relatively simple and convenient, making it suitable for on-site installation and significantly improving construction efficiency.

[0069] In some embodiments, the bolt 14 is a U-bolt.

[0070] Specifically, the shape of the U-shaped bolt can be better fixed in the fixing hole 13, and at the same time has better resistance to vibration and shock, thereby preventing the bolt 14 from loosening and falling off due to vibration, and improving the reliability of the connection.

[0071] The U-shaped bolt can be selected with a cross-sectional diameter size that matches the U-shape of the component pressing block 1, so that the U-shaped bolt and the component pressing block 1 can be completely fitted together and provide sufficient support area. While locking with the bottom, it provides support for the side wall of the component pressing block 1, effectively reducing the damage caused to the component pressing block 1 during the embedding process of the insert 5.

[0072] In some embodiments, the component pressing block 1 is made of aluminum alloy.

[0073] Specifically, aluminum alloy has a lighter weight and higher strength, which helps to reduce weight. It also has good corrosion resistance and can resist oxidation or corrosion to a certain extent, thereby extending the service life of the component compact 1.

[0074] In some embodiments, the distance adjusting member is made of plastic.

[0075] Specifically, the spacing adjustment component made of plastic material can play a certain shock-absorbing and buffering role, reducing the impact of vibration transmission or collision.

[0076] Compared to metal, plastic spacing adjustment members are lighter, helping to reduce the overall weight. Plastic spacing adjustment members have good insulation and corrosion resistance, protecting other components from the external environment and are suitable for the external environment in which the photovoltaic module 3 is located.

[0077] Those skilled in the art will readily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.

[0078] This application is intended to cover any modifications, uses or adaptations of the present application that follow the general principles of the present application and include common knowledge or customary technical means in the technical field that are not disclosed in this application.

[0079] The description and examples are to be considered as exemplary only, with the true scope and spirit of the present application being indicated by the claims. It should be understood that the present application is not limited to the precise construction described and illustrated in the drawings, and that various modifications and variations may be made without departing from the scope thereof.
