Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and specifically provides a mounting bracket for a photovoltaic module. Background Art

[0002] In practical applications, photovoltaic modules usually need to first fix the mounting bracket to the area where the photovoltaic module is to be installed, and then fix the photovoltaic module to the mounting bracket. Photovoltaic modules usually include photovoltaic glass and a frame for supporting the installation of photovoltaic glass. The mounting bracket usually includes multiple beams arranged side by side. The multiple beams usually have a height difference so that the photovoltaic module can be tilted to better receive light.

[0003] During the installation of photovoltaic modules, the frame needs to be fixedly connected to the beam on the mounting bracket, and the frame usually has a certain height. This results in a height difference between the back of the photovoltaic glass and the beam after installation, and the photovoltaic glass cannot be effectively supported. Photovoltaic modules are installed in various complex environments. Under the influence of natural conditions or human factors, photovoltaic glass will inevitably be subjected to various mechanical pressures. In this case, photovoltaic glass may be deformed, and even glass panels may burst or cells may be cracked.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0005] The present application aims to solve the above-mentioned technical problem, namely, to solve the problem that after the installation of existing photovoltaic modules, the photovoltaic glass cannot be effectively supported, which may cause glass explosion or hidden cracks in the battery cells.

[0006] To this end, the present application provides a mounting bracket for a photovoltaic assembly, wherein the photovoltaic assembly includes photovoltaic glass and a frame for mounting the photovoltaic glass, and the mounting bracket includes:

[0007] A base, on which a support beam for supporting and connecting the frame is arranged;

[0008] An auxiliary support member has one end connected to the support beam and the other end extending toward the direction of the photovoltaic glass to support the photovoltaic glass.

[0009] When the above technical solution is adopted, after the photovoltaic module is fixed on the mounting bracket, the frame supports the four edges of the photovoltaic module, and the auxiliary support members support the middle area of ​​the photovoltaic glass. When the photovoltaic glass is subjected to mechanical loads, the pressure can be transmitted to the support beam and the base through the auxiliary support members, thereby reducing the deformation of the photovoltaic glass and further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0010] In a technical solution of the above-mentioned mounting bracket, the surface of the support beam used to support the photovoltaic glass is provided with a groove along the extension direction of the support beam, one end of the auxiliary support member is located in the groove, and the other end extends out of the groove.

[0011] When the above technical solution is adopted, the auxiliary support member is installed in the groove, and no other installation structure is required. The photovoltaic glass and the mechanical load thereon can be transferred to the support beam through the auxiliary support member.

[0012] In a technical solution of the above-mentioned mounting bracket, the auxiliary support member includes a first component arranged in the groove and a second component connected to the first component and extending out of the groove, the first component is adapted to the groove to limit the displacement of the second component, and the second component has a working surface for supporting the photovoltaic glass.

[0013] When the above technical solution is adopted, the first component is configured to have a shape that matches the cross section of the groove, and no other locking structure is required, thereby simplifying the overall structure of the mounting bracket.

[0014] In a technical solution of the above-mentioned mounting bracket, the extension direction of the first component and the second component are both consistent with the extension direction of the support beam.

[0015] When the above technical solution is adopted, a specific method of providing an auxiliary support member is provided.

[0016] In a technical solution of the above-mentioned mounting bracket, a plurality of support beams are arranged side by side, and each of the auxiliary support members includes the first components respectively arranged in the grooves of each of the support beams, and the second components connected between the plurality of the first components, so that the extension direction of the second component is arranged at an angle to the extension direction of the support beam.

[0017] When adopting the above technical solution, another specific method of providing an auxiliary support is provided. In this method, the contact area between the auxiliary support and the photovoltaic glass is larger and the distribution of the contact points is more even. Each position of the photovoltaic glass can be effectively supported, thereby further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0018] In a technical solution of the above-mentioned mounting bracket, the surface area of ​​the working surface is larger than the cross-sectional area of ​​the first component.

[0019] When the above technical solution is adopted, the larger the surface area of ​​the working surface, the larger the contact area between the auxiliary support member and the photovoltaic glass, thereby effectively improving the supporting effect.

[0020] In a technical solution of the above-mentioned mounting bracket, a gap is provided between the first component and the bottom surface of the groove, so that the surface of the second component facing away from the working surface abuts against the support beam.

[0021] When the above technical solution is adopted, the gravity of the photovoltaic module and the mechanical load from the outside act on the upper surface of the support beam through the second component, and the upper surface of the support beam is the main force-bearing surface.

[0022] In a technical solution of the above-mentioned mounting bracket, the first component abuts against the bottom surface of the groove, thereby supporting the second component.

[0023] When the above technical solution is adopted, the gravity of the photovoltaic module and the mechanical load from the outside act on the bottom surface of the groove through the second component and the first component in turn, and the bottom surface of the groove is the main force-bearing surface.

[0024] In a technical solution of the above-mentioned mounting bracket, the working surface is provided with a shock-absorbing layer.

[0025] When the above technical solution is adopted, the shock-absorbing layer can absorb vibration energy, thereby further reducing the probability of photovoltaic glass bursting or hidden cracks.

[0026] In a technical solution of the above-mentioned mounting bracket, a plurality of through holes are provided at intervals on the bottom surface of the groove.

[0027] When the above technical solution is adopted, the provision of the through holes can not only reduce the weight of the support beam and meet the lightweight design requirements, but also rainwater can be discharged downward through the through holes on rainy and snowy days to prevent rainwater from accumulating in the grooves and reduce the corrosion of the support beam by rainwater.

[0038] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0039] It should be noted that in the description of this application, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description, and does not indicate or imply that the relevant devices or components must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application. In addition, the ordinal numbers "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] Reference Figure 1, is a schematic diagram of the partial structure of a photovoltaic module, which includes a frame 100 and a photovoltaic glass 200. The frame 100 is surrounded to form a square frame structure, and the edges of the photovoltaic glass 200 are respectively embedded in the grooves formed on the inner side of the frame 100. For the convenience of description, the surface of the photovoltaic glass 200 that receives light, that is, the upper surface in the figure, is called the front of the photovoltaic glass 200, and the backlight surface of the photovoltaic glass 200, that is, the lower surface in the figure, is called the back of the photovoltaic glass 200. It can be seen from the figure that there is a certain height difference between the back of the photovoltaic glass 200 and the bottom surface of the frame 100. After the photovoltaic module is installed, the bottom surface of the frame 100 is in contact with the crossbeam on the mounting bracket. Therefore, this inevitably leads to the middle area on the back of the photovoltaic glass 200 cannot be effectively supported. When the photovoltaic glass 200 is subjected to a large mechanical pressure, it will cause the photovoltaic glass 200 to deform, and even cause the glass to burst or the battery cell to crack.

[0042] Reference Figure 2 , is a schematic diagram of the overall structure of a mounting bracket for a photovoltaic module according to an embodiment of the present application, which includes a base 1 and a support beam 2 fixedly connected to the top of the base, and the support beam 2 is used to connect to the frame of the photovoltaic module to support the frame. The base 1 serves as a supporting foundation for the installation of the photovoltaic module, and it can be formed by connecting multiple profiles or square tubes. Multiple support beams 2 can be arranged side by side on the top of the base 1. In an optional manner, multiple support beams 2 are arranged horizontally, and there is a height difference between adjacent support beams 2, so that after the photovoltaic module is installed on the support beam 2, the photovoltaic glass is arranged at an angle to better receive light.

[0043] Reference Figure 3 , is a cross-sectional view of a support beam according to an embodiment of the present application. A surface of the support beam 2 for supporting the photovoltaic glass (i.e., the upper surface in the figure) is provided with a groove 21 along the extension direction of the support beam 2, so that the cross-section of the support beam 2 is a U-shaped or C-shaped structure. This arrangement is to reduce the overall weight of the support beam 2 while ensuring the structural rigidity of the support beam 2, while saving material costs. Of course, in actual processing, the support beam 2 can be a prefabricated C-shaped channel steel or other structure.

[0044] Further, refer to Figure 2 The bottom surface of the groove 21 is also provided with a plurality of through holes 211 at intervals. This can not only further reduce the weight of the support beam 2 and meet the lightweight design requirements, but also allow rainwater to be discharged downward through the through holes 211 on rainy and snowy days, preventing rainwater from accumulating in the groove 21 and reducing the corrosion of the support beam 2 by rainwater.

[0045] The mounting bracket also includes an auxiliary support member 3 arranged on the support beam 2, one end of the auxiliary support member 3 is connected to the support beam 2, and the other end extends toward the back side of the photovoltaic glass, thereby supporting the photovoltaic glass.

[0046] In this way, after the photovoltaic module is fixed on the mounting bracket, the frame supports the edges of the photovoltaic module on all sides, and the auxiliary support member 3 supports the middle area of ​​the photovoltaic glass. When the photovoltaic glass is subjected to mechanical loads, the pressure can be transmitted to the support beam 2 and the base 1 through the auxiliary support member 3, thereby reducing the deformation of the photovoltaic glass and further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0047] Reference Figure 3 As a possible implementation of the present application, the auxiliary support member 3 includes a first component 31 and a second component 32, wherein the first component 31 is located in the groove 21, and the second component 32 extends out of the groove 21. The surface of the second component 32 facing away from the first component 31 is a working surface for supporting the photovoltaic glass. In order to absorb vibration energy, a shock-absorbing layer can also be fixedly arranged on the working surface, thereby further reducing the probability of explosion or hidden cracks of the photovoltaic glass. The first component 31 is adapted to the cross-sectional shape of the groove 21, so that the first component 31 can be slidably arranged in the groove 21, limiting the displacement of the entire auxiliary support member 3 in a direction perpendicular to the extension direction of the support beam 2.

[0048] The cross section of the auxiliary support member 3 is in a "T" shape. Figure 3 In the illustrated embodiment, there is a gap between the first component 31 and the bottom surface of the groove 21, so that the surface of the second component 32 facing away from the first component 31 abuts against the upper surface of the support beam 2. At this time, after the photovoltaic component is fixed on the mounting bracket, the gravity of the photovoltaic component and the mechanical load from the outside act on the upper surface of the support beam 2 through the second component 32.

[0049] Of course, the cooperation between the auxiliary support member 3 and the support beam 2 is not limited to this. Figure 4 In another implementation, the lower end of the first component 31 abuts against the bottom surface of the groove 21. At this time, the bottom surface of the groove 21 supports the second component 32, the gravity of the photovoltaic module and the mechanical load from the outside, and the bottom surface of the groove 21 serves as a force-bearing part. It should be noted that, in the above case, by adjusting the height of the first component 31, the surface of the second component 32 away from the first component 31 can contact the upper surface of the support beam 2, or there can be a gap between the surface of the second component 32 and the upper surface of the support beam 2. When the surface of the second component 32 away from the first component 31 can contact the upper surface of the support beam 2, the upper surface of the support beam 2 can bear part of the gravity from the photovoltaic module and the mechanical load from the outside.

[0050] As an implementation of the present application, the extension direction of the first component 31 and the second component 32 are consistent with the extension direction of the support beam 2. In this way, each support beam 2 can correspond to an auxiliary support member 3, and the length of the first component 31 and the second component 32 are the same as the length of the support beam 2, so as to increase the contact area between the auxiliary support member 3 and the support beam 2.

[0051] In order to further increase the contact area between the auxiliary support member 3 and the support beam 2 , thereby enhancing the supporting effect, the surface area of ​​the working surface of the second component 32 is larger than the cross-sectional area of ​​the first component 31 .

[0052] Reference Figure 5 In some other implementations of the present application, the extension direction of the second component 32 is set at an angle to the extension direction of the support beam 2. At this time, different from the above-mentioned embodiment, each auxiliary support member 3 includes a first component 31 respectively arranged in the groove 21 of each support beam 2, that is, each auxiliary support member 3 includes multiple first components 31. For example, when the number of support beams 2 is two, the number of first components 31 is two, and the second component 32 is connected between the two first components 31.

[0053] It should be noted that the extension direction of the second component 32 and the extension direction of the support beam 2 being “set at an angle” mentioned above means that the extension direction of the second component 32 is not parallel to the extension direction of the support beam 2. Specifically, the extension direction of the second component 32 can be perpendicular to the support beam 2, or can be inclined relative to the extension direction of the support beam 2. This is not restricted in the present application.

[0054] It should also be noted that, based on the above embodiment, for each auxiliary support member 3, the groove 21 of each support beam 2 is not limited to having only one first component 31, and the second component 32 is not limited to extending along a fixed direction. Figure 6 In one implementation, two first components 31 are disposed in the groove 21 of each support beam 2, and the second component 32 is disposed in an "X" shape, and the two straight sections of the "X"-shaped first component 31 are respectively connected to the two first components 31 that are staggered with each other in the two support beams 2.

[0055] Furthermore, in some other implementations, support components can also be connected between the first components 31 in each support beam 2, so that the second component 32 is a mesh structure that is interlaced in all directions. In short, the higher the complexity of the second component 32, the larger the contact area between it and the photovoltaic glass, and the more uniform the distribution of the contact points, so that each position of the photovoltaic glass can be effectively supported, thereby further reducing the probability of photovoltaic glass bursting or hidden cracks. Therefore, without departing from the principles of the present application, equal or similar replacements made to the combination of the first component 31 and the second component 32 in the auxiliary support member 3 should be within the scope of protection of the present application.

[0056] Similarly, for the above embodiment, within a unit length, the surface area of ​​the working surface corresponding to the second component 32 is larger than the cross-sectional area of ​​the first component 31, so as to increase the contact area between the second component 32 and the photovoltaic glass, thereby improving the supporting effect.

[0057] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
