Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a fixed component and a photovoltaic system. Background Technology

[0002] With the development of photovoltaic (PV) module technology and the pursuit of cost reduction and efficiency improvement, PV modules have become increasingly larger in recent years. This increase in module area has also led to higher risks related to mechanical loads. Faced with market and competitive pressures, PV manufacturers are striving to reduce costs while ensuring the mechanical load performance of their modules.

[0003] Currently, the primary installation method for solar photovoltaic (PV) modules used in various locations is clamp mounting. This method securely fixes the PV modules to the support structure, preventing them from shifting due to wind and vibration. The clamps apply pressure evenly to ensure tight contact between the PV module and the support, providing stable support. Typically, the clamps are placed at the edge of the PV module and secured to the support structure with bolts. The installation process is relatively simple, relying mainly on the shape and material of the clamps to provide fixing force. It is well-suited for rapid installation of PV modules and is applicable to both flat and sloping PV systems. It effectively distributes stress, is easy to inspect and replace, and regular checks of the clamp tightness can reduce potential safety hazards.

[0004] However, in the above installation methods, improper installation of the clamping blocks may lead to uneven stress on the photovoltaic modules, increasing the risk of breakage or deformation. Under the action of external forces such as strong winds or vibrations, the clamping blocks may loosen, affecting the stability and safety of the photovoltaic modules. The installation of the clamping blocks requires regular inspection and maintenance to ensure their stability in long-term operation, increasing the later maintenance costs and workload. In some cases, the accurate positioning and installation of the clamping blocks may require higher technical requirements, increasing the complexity of the installation. Furthermore, under extreme climatic conditions, such as snow pressure or freezing, the clamping blocks' fixing ability is insufficient. Utility Model Content

[0041] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0042] The specific structure is as follows: Figures 1 to 4 As shown.

[0043] This embodiment provides a fixing component for fixing the frame 1 of a photovoltaic module to a photovoltaic bracket 2. The fixing component includes: a first fastening block, a second fastening block 6, and a fastener. The first fastening block includes a pressing part 3 and a fixing connection part 4, and the pressing part 3 can press the frame 1 of the photovoltaic module. The second fastening block 6 is disposed below the first fastening block, and a clamping space for clamping and fixing the frame 1 of the photovoltaic module is formed between it and the pressing part 3. One end of the second fastening block 6 is provided with a slot 13 with the slot facing the other end for inserting the frame 1 of the photovoltaic module. The fastener is used to connect the fixing connection part 4, the second fastening block 6, and the photovoltaic bracket 2.

[0044] In this embodiment, during installation, the frame 1 of the photovoltaic module is clipped into the slot 13, and the pressing part 3 of the first fastening block presses it onto the frame 1 of the photovoltaic module, placing the frame 1 of the photovoltaic module within the clamping space. The fixing connection part 4, the second fastening block 6, and the photovoltaic bracket 2 are connected and fixed by fasteners. The cooperation of the first fastening block, the second fastening block 6, and the fasteners ensures that the frame 1 of the photovoltaic module is firmly fixed. At the same time, the stress on the frame 1 of the photovoltaic module can be dispersed, avoiding local concentration and reducing the risk of photovoltaic module breakage or deformation. This improves the installation tightness of the photovoltaic module in harsh environments, meets the installation requirements in harsh environments, expands the application range of the photovoltaic module, and, due to its good stability, does not require regular inspection and maintenance, ensuring its stability in long-term operation and reducing later maintenance costs and workload. Since the first fastening block and the second fastening block 6 are installed together, the positioning and installation of the first fastening block do not require high technical requirements, reducing the complexity of installation.

[0045] In this embodiment, the pressing part 3 presses against the A side 16 of the frame 1 of the photovoltaic module, and the slot 13 is engaged with the C side 17 of the frame 1 of the photovoltaic module, so as to ensure the stability of the frame 1 of the photovoltaic module.

[0046] In an optional technical solution of this embodiment, the second fastening block 6 is provided with an elongated hole 15 for engaging with a fastener. This facilitates adjustment of the installation position of the second fastening block 6.

[0047] In this embodiment, the second fastening block 6 is plate-shaped, and one end is bent upwards and then bent to the other end to form a slot 13. The structure is simple and easy to manufacture.

[0048] In the optional technical solution of this embodiment, the clamping part 3 includes a pressure plate 5 and a side plate 7; the pressure plate 5 is connected to the first side of the side plate 7 and is opposite to the second fastening block 6, and a clamping space is formed between the pressure plate 5 and the second fastening block 6; the fixed connection part 4 is located on the second side of the side plate 7 away from the pressure plate 5. The structure is simple and the installation is stable.

[0049] In the optional technical solution of this embodiment, an arc-shaped groove 8 is provided at the angle between the pressure plate 5 and the side plate 7.

[0050] In this embodiment, the arc-shaped groove 8 allows for an expansion of the clamping space on the frame 1 of the photovoltaic module during installation, improving installation convenience and applicability, and significantly enhancing stress buffering effect. On one hand, the arc-shaped groove 8 eliminates stress concentration points at right angles, preventing fatigue and cracking caused by excessive stress accumulation; on the other hand, the movement space reserved in the arc-shaped groove 8 allows the clamping part 3 to undergo slight elastic displacement under external forces such as strong winds and temperature changes, absorbing energy through deformation and reducing the overall impact force on the photovoltaic module, thereby effectively extending the service life and operational stability of the photovoltaic module.

[0051] In the optional technical solution of this embodiment, the pressure plate 5 is provided with an anti-slip structure on the side facing the second fastening block 6; the anti-slip structure abuts against the A-side 16 of the photovoltaic module frame 1, and the anti-slip structure increases the friction between the pressure plate 5 and the A-side 16 of the photovoltaic module frame 1, ensuring the stability of the clamping and effectively preventing the displacement of the photovoltaic module frame 1; and / or; the second fastening block 6 is provided with an anti-slip structure on the side facing the pressure plate 5, and the anti-slip structure is used to abut against the C-side 17 of the photovoltaic module frame 1, and the anti-slip structure increases the friction between the second fastening block 6 and the C-side 17 of the photovoltaic module frame 1, ensuring the stability of the clamping and effectively preventing the displacement of the photovoltaic module frame 1.

[0052] In the optional technical solution of this embodiment, the anti-slip structure includes multiple spaced anti-slip ribs 9 along the direction from the first side to the second side of the side plate 7. The structure is simple and provides better anti-slip effect. The anti-slip ribs 9 tightly grip the surface of the photovoltaic module frame 1, enhancing the stability of the mechanical connection, increasing the friction between the ribs and the photovoltaic module frame 1, and effectively resisting lateral displacement caused by external forces such as strong winds and blizzards. In extreme weather conditions, the anti-slip ribs 9 form a stable grip through multi-point contact, preventing loosening and ensuring that the photovoltaic module maintains a reliable connection for a long time, reducing the risk of reduced power generation efficiency due to connection failure. During compression, the anti-slip ribs 9 evenly distribute concentrated stress to a larger area of ​​the photovoltaic module frame 1, optimizing stress dispersion and avoiding localized stress overload. The cross-section of the anti-slip ribs 9 can be triangular, trapezoidal, or arc-shaped. Its unique structure allows external forces to be gradually transmitted along the inclined surface of the anti-slip ribs 9, reducing direct impact on the photovoltaic module frame 1, effectively preventing deformation and cracking of the photovoltaic module frame 1, ensuring the structural integrity of the photovoltaic module in complex environments, and extending its service life. Meanwhile, the anti-slip ribs 9 work in conjunction with the arc-shaped grooves 8 to enhance the adaptability of the frame 1 of photovoltaic modules with different surface roughness, enabling secure installation without special treatment of the frame 1 of the photovoltaic modules. During installation, the anti-slip ribs 9 automatically embed into the tiny grooves on the frame 1 of the photovoltaic modules, quickly positioning and locking them, reducing the difficulty and time cost of manual installation, while ensuring that photovoltaic modules of different batches and specifications can achieve stable and reliable connection.

[0053] This embodiment is not limited to this; the anti-slip structure can also be an anti-slip strip, anti-slip bumps, or anti-slip pad, etc., as long as it meets the requirements.

[0054] In the optional technical solution of this embodiment, the fixed connection part 4 includes a support plate 10 and a connecting plate 11; the support plate 10 is connected to the pressing part 3 through the connecting plate 11, and the support plate 10 abuts against the second fastening block 6; the fastener is used to connect the connecting plate 11, the second fastening block 6 and the photovoltaic bracket 2.

[0055] In this embodiment, the fastener passes through the connecting plate 11, the second fastening block 6, and the photovoltaic bracket 2 for connection. At the same time, the support plate 10 abuts against the second fastening block 6. There is a hollow space between the support plate 10 and the second fastening block 6. The overall structure is lightweight and saves materials during manufacturing. However, it is not limited to this. The fixed connection part 4 can also be a fixed block, that is, there is no hollow space.

[0056] In the optional technical solution of this embodiment, an abutment seat 12 is provided at the end of the support plate 10 that abuts against the second fastening block 6; the width of the abutment seat 12 is greater than the width of the support plate 10. This increases the abutment area and ensures the stability of the abutment.

[0057] In this embodiment, the fastener may be a rivet or a pin.

[0058] In the optional technical solution of this embodiment, the fastener includes a bolt 14, the fixed connection part 4 is provided with a threaded connection hole, and the thread of the bolt 14 is connected to the thread of the threaded connection hole through a helical spring.

[0059] In this embodiment, the bolt 14 can be directly screwed onto the photovoltaic bracket 2 to achieve connection, or the fastener can also include a nut that matches the bolt 14, and the bolt 14 passes through the photovoltaic bracket 2 and is fixed by the nut.

[0060] In this embodiment, the helical spring and the threaded connection hole can be screwed into the threaded connection hole, and the thread of the bolt 14 and the helical spring can be screwed into the helical spring. The helical spring is made of a high-elasticity shape memory alloy and is arranged axially along the bolt 14, forming a composite elastic structure with the threaded connection hole. This significantly improves the anti-loosening performance, maintaining tightness even under vibration, and also acts as a buffer to increase the service life of the bolt 14 and reduce maintenance. Furthermore, compared to traditional external anti-loosening structures, the embedded helical spring does not change the external dimensions of the bolt 14 and can be adapted to existing standard nuts and connected components. By dispersing stress, it avoids local overload, reduces fatigue damage caused by long-term stress, delays structural aging, and effectively extends the service life of the fastening block and the connected components. In addition, the helical spring undergoes elastic deformation under pressure, accumulating elastic potential energy; under the thrust of the helical spring, it expands outward, tightly fitting the outer wall of the bolt 14 and the inner wall of the threaded connection hole, forming multi-directional friction. The special structural design provides buffer protection for the photovoltaic module and bolt 14, reducing wear caused by vibration and avoiding problems such as loosening of bolt 14 and deformation of hole positions caused by high-frequency vibration. This extends the service life of the overall fastening system, reduces the frequency of maintenance and replacement, and lowers the overall cost of use.

[0061] This embodiment provides a photovoltaic system including a photovoltaic module, a photovoltaic bracket 2, and the aforementioned fixing components. Therefore, the technical advantages and effects achieved by this photovoltaic system include the technical advantages and effects achieved by the aforementioned fixing components, which will not be elaborated here.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
