Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a photovoltaic module installation system. Background Technology

[0002] Currently, photovoltaic (PV) power generation systems refer to power generation systems that directly convert solar radiation energy into electrical energy using the photovoltaic effect of PV modules. The energy of PV power generation systems comes from inexhaustible solar energy, making it a clean, safe, and renewable energy source. Building-integrated photovoltaics (BIPV), on the other hand, uses PV modules as building components or materials, making them an integral part of the building while also providing power generation capabilities. This avoids occupying excessive land resources, which is especially important for urban buildings where land is expensive.

[0003] In related technologies, photovoltaic tiles mostly use plastic or polymer material bases. The bases are processed by injection molding, and then the photovoltaic modules are bonded to the bases. The photovoltaic tiles are then fixed to the purlins with nails to complete the installation of the photovoltaic system.

[0004] However, the inventors recognized that the above installation method has the following drawbacks in practical use: the plastic or polymer material base is prone to aging in long-term outdoor environments such as ultraviolet radiation, high temperature, and humidity, leading to decreased material strength and increased brittleness. This affects the structural support capacity of the diamond-shaped photovoltaic tiles and increases the risk of module detachment. Utility Model Content

[0011] In one embodiment, the first elastic arm and / or the second elastic arm are provided with elastic hooks, which extend into the embedding groove when the first elastic arm and the second elastic arm approach each other.

[0012] In one embodiment, the mounting base further includes an extension having mounting holes, the extension being mounted on the roof by fasteners.

[0015] In one embodiment, the second fastener has a first clamping surface and a second clamping surface, and a clamping space is formed between the first clamping surface and the second clamping surface, so that the end of the photovoltaic module is mounted on the second fastener.

[0016] In one embodiment, the first fixing member is further provided with a buffer member, which is disposed between the first fixing member and the photovoltaic module, so that the surface of the photovoltaic module elastically abuts against the first fixing member.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0032] In some embodiments, such as Figures 1-5 As shown, this application provides a photovoltaic module installation system, including: a photovoltaic module 1 and an installation component 2. The installation component 2 is arranged along a first direction Q of the roof to fix the photovoltaic module 1 to the roof. Two adjacent photovoltaic modules 1 are staggered along a second direction C. The lower part of the upper photovoltaic module 1 is higher than the upper part of the lower photovoltaic module 1 along the second direction C to form an installation space 3 along the second direction C. The installation component 2 is disposed in the installation space 3. The installation component 2 includes a first fixing member 21, a second fixing member 22, a locking member 23, and a fixing seat 24. The fixing seat 24 is installed on the roof. The first fixing member 21 is used to install the upper photovoltaic module 1 along the second direction C. The second fixing member 22 is used to install the lower photovoltaic module 1 along the second direction C. The second fixing member 22 and the fixing seat 24 cooperate with each other to restrict the movement of the second fixing member 22 along the second direction C. The locking member 23 is adapted to connect the first fixing member 21 and the fixing seat 24 to restrict the movement of the first fixing member 21 along the second direction C.

[0033] In some embodiments, such as Figure 1 As shown, two adjacent photovoltaic modules 1 are staggered along the second direction C, with the lower part of the upper photovoltaic module 1 being higher than the upper part of the lower photovoltaic module 1 to form a stepped load-bearing structure. This allows the roof load to be evenly distributed onto the fixing base 24, avoiding roof deformation caused by local stress concentration. At the same time, the lower part of the upper photovoltaic module 1 shields the upper part of the lower photovoltaic module 1 to increase the rainproof effect of the photovoltaic module installation system. When rainwater slides down the surface of the photovoltaic module 1, it is blocked by the upper photovoltaic module 1, preventing rainwater from flowing back into the installation space 3 and preventing the installation components 2 from rusting and corroding.

[0034] In some embodiments, the first direction Q is the extending direction of the photovoltaic module 1, and the second direction C is the direction perpendicular to the plane where the photovoltaic module 1 is located. That is, the first direction Q is perpendicular to the second direction C.

[0035] In some embodiments, the mounting assembly 2 includes a first fixing member 21, a second fixing member 22, a locking member 23, and a fixing base 24, such as Figure 2 As shown, the first fixing member 21 and the fixing base 24 are connected to each other by the locking member 23. Compared with the installation method of installing the locking member 23 on the photovoltaic module 1 by fasteners, the tension of the fasteners will directly act on the frame or glass surface of the photovoltaic module 1. When subjected to wind, snow and other loads for a long time, it is easy to cause cracks in the photovoltaic module 1. Moreover, the fixing of the locking member 23 is more convenient, shortens the installation time of the photovoltaic module 1, and increases the reliability of the installation of the first fixing member 21.

[0036] In some embodiments, the second fixing member 22 and the fixing seat 24 are interlocked, which can shorten the installation and disassembly time of the photovoltaic module 1, make the single panel of the photovoltaic module 1 easier to install and remove, and the fixing seat 24 can also restrict the movement of the second fixing member 22, increasing the stability of the second fixing member 22.

[0037] In some embodiments, the locking member 23 is provided with a first locking hook 231 along the first direction Q, and the fixing base 24 is provided with a first slot 241 that engages with the first locking hook 231, so that the locking member 23 is connected to the fixing base 24.

[0038] In some embodiments, such as Figure 3 As shown, the first locking hook 231 extends along the first direction Q and engages with the first slot 241, eliminating the need for additional connectors and significantly improving installation efficiency. Through this snap-fit ​​connection, the first locking hook 231 and the first slot 241 are tightly engaged, forming a mechanical self-locking mechanism that effectively resists displacement caused by wind or roof vibration.

[0039] In some embodiments, the locking member 23 further includes a second locking hook 232, which is disposed opposite to the first locking hook 231 along the first direction Q. The first fixing member 21 is provided with an embedding groove 211, and the second locking hook 232 engages with the embedding groove 211.

[0040] In some embodiments, such as Figure 3 As shown, the second locking hook 232 is engaged with the embedded groove 211, thereby limiting the photovoltaic module 1 from shifting, preventing the photovoltaic module 1 from falling off, and thus improving the wind resistance of the photovoltaic module 1.

[0041] Alternatively, the embedding groove 211 is provided on the locking member 23, and the second locking hook 232 is provided on the first fixing member 21. The second locking hook 232 cooperates with the embedding groove 211 to lock and thus restrict the photovoltaic module 1 from shifting.

[0042] In some embodiments, the second locking hook 232 includes a first elastic arm 2321 and a second elastic arm 2322, the first elastic arm 2321 and the second elastic arm 2322 being disposed opposite to each other along a second direction C, and the first elastic arm 2321 and the second elastic arm 2322 being close to each other to be embedded in the embedding groove 211.

[0043] In some embodiments, such as Figure 3 As shown, the first elastic arm 2321 and the second elastic arm 2322 are arranged opposite each other along the second direction C to form a U-shaped elastic structure. When the roof is subjected to wind pressure or vibration, the two elastic arms can absorb the vibration through slight deformation, avoiding stress abrupt changes caused by rigid clamping. During installation, the installer inserts the second elastic arm 2322 into the embedding groove 211, so that the second elastic arm 2322 and the embedding groove 211 are interlocked. Since the end face of the first elastic arm 2321 is inclined, the first elastic arm 2321 slides into the embedding groove 211 to complete the interlocking, making the installation process more convenient.

[0044] In some embodiments, such as Figure 3 As shown, the first elastic arm 2321 and / or the second elastic arm 2322 are provided with elastic hooks 2323. When the first elastic arm 2321 and the second elastic arm 2322 are embedded in the embedding groove 211, the elastic hooks 2323 and the embedding groove 211 are engaged with each other to prevent the first elastic arm 2321 and the second elastic arm 2322 from disengaging from the embedding groove 211.

[0045] In some embodiments, the first elastic arm 2321 may be provided with an elastic hook 2323, or the second elastic arm 2322 may be provided with an elastic hook 2323, or both may be provided with an elastic hook 2323, which is not limited here.

[0046] In some embodiments, the fixing base 24 further includes an extension 242, the roof is provided with a tile purlin 4, and the fixing base 24 is installed on the tile purlin 4 by fasteners. The extension 242 is provided with a mounting hole 2421, the tile purlin 4 is provided with a threaded hole that cooperates with the mounting hole 2421, and the fastener passes through the mounting hole 2421 and engages with the thread in the threaded hole.

[0047] In some embodiments, such as Figure 2 and Figure 3As shown, the roof is provided with a tile purlin 4, and the fixing seat 24 is provided with an extension 242. The extension 242 is provided with a mounting hole 2421, and the tile purlin 4 is provided with a threaded hole. The threaded hole and the mounting hole 2421 coincide with each other, so that the fastener passes through the mounting hole 2421 and engages with the thread in the threaded hole. Thus, the fixing seat 24 is detachably installed on the tile purlin 4. Installation by fastener can be easily disassembled, shortening the maintenance and replacement time. At the same time, the mounting hole 2421 is machined on the extension 242, making the processing technology simpler.

[0048] In some embodiments, the first fixing member 21 is provided with a receiving surface 212, which abuts against at least a portion of the side of the upper photovoltaic module 1, so that the first fixing member 21 supports the upper photovoltaic module 1 along the second direction C.

[0049] In some embodiments, such as Figure 4 As shown, the first fixing member 21 has a receiving surface 212 along the second direction C. The receiving surface 212 abuts against the side of the photovoltaic module 1 near the purlin 4, so that the first fixing member 21 and the photovoltaic module 1 are in surface contact, avoiding stress concentration that could cause the photovoltaic module 1 to break.

[0050] In some embodiments, a positioning block 2121 is provided on the receiving surface 212, and the positioning block 2121 abuts against the end of the photovoltaic module 1 along the first direction Q to restrict the movement of the photovoltaic module 1 along the first direction Q.

[0051] In some embodiments, such as Figure 4 As shown, the positioning block 2121 is disposed on the receiving surface 212, and the positioning block 2121 protrudes relative to the receiving surface 212 along the second direction C, so that the positioning block 2121 can abut against the end of the photovoltaic module 1. On the one hand, it restricts the photovoltaic module 1 from shifting, so as to avoid the photovoltaic module 1 from shifting and affecting the power generation. On the other hand, the photovoltaic module 1 undergoes thermal expansion and contraction under the temperature difference between day and night. If it is fixed by screws, it will cause the photovoltaic module 1 to deform. Therefore, the positioning block 2121 restricts the movement of the photovoltaic module 1, thus avoiding the problem of deformation.

[0052] In some embodiments, flexible elements are provided between the positioning block 2121 and the photovoltaic module 1, and between the receiving surface 212 and the photovoltaic module 1, to provide buffering. When the photovoltaic module 1 is heated and expands, the flexible elements are squeezed to increase the space for placing the photovoltaic module 1 and prevent the photovoltaic module 1 from being squeezed and deformed.

[0053] In some embodiments, the fixing base 24 is further provided with a receiving groove 243, which is adapted to receive the second fixing member 22 so that the second fixing member 22 is interconnected with the fixing base 24. Figure 3As shown, the fixing base 24 is provided with a receiving groove 243. The shape of the receiving groove 243 is adapted to the contour of the second fixing member 22 to avoid incorrect installation or misalignment of the second fixing member 22. At the same time, while fixing the second fixing member 22, the receiving groove 243 also leaves some space, specifically as shown in the figure. Figure 6 As shown, the second fixing member 22 can rotate at a certain angle, so that the installed photovoltaic module 1 can adapt to the roof structure and is more aesthetically pleasing after installation.

[0054] In some embodiments, the second fixing member 22 is provided with a first clamping surface 221 and a second clamping surface 222, and a clamping space 223 is formed between the first clamping surface 221 and the second clamping surface 222, so that the end of the photovoltaic module 1 is mounted on the second fixing member 22.

[0055] In some embodiments, such as Figure 4 As shown, the second fixing member 22 has a first clamping surface 221 and a second clamping surface 222 that are arranged opposite to each other. The first clamping surface 221 and the second clamping surface 222 form a compression fixing on the two sides of the photovoltaic module 1 to limit the displacement of the photovoltaic module 1 in the vertical direction. The end of the photovoltaic module 1 is set in the clamping space 223, and it can be installed without the need for additional fixing devices, making the fixing method of the photovoltaic module 1 simpler and the installation time shorter.

[0056] In some embodiments, such as Figure 2 as well as Figure 4 As shown, the first fixing member 21 is further provided with a first buffer member 213. The first buffer member 213 is disposed between the first fixing member 21 and the photovoltaic module 1, so that the surface of the photovoltaic module 1 elastically abuts against the first fixing member 21. The first buffer member 213 absorbs stress through elastic deformation, avoiding direct rigid contact between the photovoltaic module 1 and the first fixing member 21, reducing the risk of cracking or microcracks in the frame, glass or internal cells of the photovoltaic module 1, and extending the service life of the photovoltaic module 1. In addition, the elasticity of the first buffer member 213 can accommodate a certain range of installation errors. By adapting and adjusting the contact state through its own deformation, it ensures that the photovoltaic module 1 and the first fixing member 21 are tightly fitted, improving the overall stability of the fixing.

[0057] In some embodiments, the second fixing member 22 is further provided with a second buffer member 224, which is disposed within the clamping space 223, so that the end of the photovoltaic module 1 elastically abuts against the first clamping surface 221 and the second clamping surface 222. Figure 3 as well as Figure 4As shown, a second buffer 224 is provided between the first clamping surface 221 and the second clamping surface 222 on both sides of the photovoltaic module 1 to avoid deformation of the frame of the photovoltaic module 1 caused by direct metal compression, and at the same time, it can reduce the wear of the photovoltaic module 1 and improve the service life of the photovoltaic module 1.

[0058] In some embodiments, the second buffer 224 has a U-shaped structure and can cover the end of the photovoltaic module 1 to prevent the photovoltaic module 1 from being worn. The material of the second buffer 224 can be any one or a combination of EPDM rubber, polyurethane or neoprene foam, and is not limited herein.
