Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and specifically provides a mounting bracket for a photovoltaic component and a photovoltaic system. 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] In a first aspect, 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] Wherein, a receiving groove for accommodating the frame is provided on the support beam, so that when the frame is arranged in the receiving groove, the distance between the photovoltaic glass and the support beam can be reduced.

[0009] When the above technical solution is adopted, when the photovoltaic module is fixed to the mounting bracket, the frame of the photovoltaic module is placed in the corresponding receiving groove. At this time, the distance between the photovoltaic glass and the upper surface of the supporting beam is reduced. When the photovoltaic glass is subjected to mechanical load, the pressure can be directly transmitted to the upper surface of the supporting beam and the base, 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, a plurality of the support beams are arranged side by side, and each of the support beams has a plurality of the accommodating grooves evenly distributed along its extension direction.

[0011] In a technical solution of the above-mentioned mounting bracket, the support beam includes a bottom wall and two side walls respectively connected to the bottom wall, and the receiving grooves are respectively opened on the two side walls.

[0012] When the above technical solution is adopted, the overall weight of the support beam can be reduced.

[0013] In a technical solution of the above-mentioned mounting bracket, an end of at least one of the side walls of the support beam away from the bottom wall is connected to a support plate, and the support plate has a working surface for supporting the photovoltaic glass.

[0014] When the above technical solution is adopted, the support plate can increase the contact area between the photovoltaic glass and the support beam, thereby improving the support effect.

[0015] In a technical solution of the above-mentioned mounting bracket, the support plate includes a first support plate, the two side walls of each support beam are connected to the first support plate, and the extension direction of the first support plate is the same as the extension direction of the support beam.

[0016] When the above technical solution is adopted, a specific form of a support plate is provided.

[0017] In a technical solution of the above-mentioned mounting bracket, the support plate includes a second support plate, and the second support plate is connected to the side walls of adjacent support beams that are opposite to each other.

[0018] When the above technical solution is adopted, the second support plate is connected between adjacent support beams, and its contact area with the photovoltaic glass is larger. Moreover, the more second support plates there are and the more their arrangements are, the more uniform the distribution of support points of the photovoltaic glass is. In this way, each position of the photovoltaic glass can be effectively supported, thereby further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0019] In a technical solution of the above-mentioned mounting bracket, a plurality of through holes are provided on the bottom wall at intervals along the extension direction of the support beam.

[0020] When the above technical solution is adopted, not only can the weight of the support beam be further reduced to 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 groove of the support beam and reduce the corrosion of the support beam by rainwater.

[0021] In a second aspect, the present application provides a photovoltaic system, comprising:

[0022] The mounting bracket described in any one of the first aspects;

[0023] A photovoltaic assembly comprises photovoltaic glass and a frame for mounting the photovoltaic glass, wherein the frame is connected to the support beam and is located in the receiving groove.

[0024] In a technical solution of the above-mentioned photovoltaic system, the depth of the receiving groove is greater than or equal to the distance between the bottom surface of the frame and the back surface of the photovoltaic glass, so that when the frame is set in the receiving groove, the photovoltaic glass is in contact with the support beam.

[0025] When the above technical solution is adopted, the deformation of the photovoltaic glass can be reduced to the maximum extent when the photovoltaic glass is under pressure.

[0026] In a technical solution of the above-mentioned photovoltaic system, a plurality of photovoltaic components are arranged on the mounting bracket, and the size of the receiving groove in the extension direction of the support beam is greater than twice the width of the bottom of the frame, so that the frames of two adjacent photovoltaic components can be located in the same receiving groove.

[0027] When the above technical solution is adopted, in terms of spatial arrangement, adjacent photovoltaic modules can be closely arranged, reducing the gap between adjacent photovoltaic modules, thus improving the utilization rate of space and the utilization rate of the mounting bracket.

[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 schematic diagram of a support beam according to an embodiment of the present application. The support beam 2 may be a structure with a U-shaped or C-shaped cross section. This configuration 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 may be a prefabricated C-shaped channel steel or other structure. Based on this, the support beam 2 includes a bottom wall 21 and two side walls 22 respectively connected to the bottom wall 21. The two side walls 22 are respectively provided with accommodating grooves 221, and the frame of the photovoltaic module can be placed in the accommodating grooves 221.

[0044] It is understandable that the number of receiving grooves 221 should be determined according to the number of photovoltaic modules. For example, for a single support beam 2, since the frame of the photovoltaic module is a square structure, the frame of the photovoltaic module has a group of relatively parallel edges. Therefore, the single support beam 2 should have at least two groups of receiving grooves 221 to accommodate the group of parallel edges of the frame.

[0045] For multiple support beams 2 arranged side by side, each support beam 2 has side walls 22 evenly distributed with receiving grooves 221 along its extension direction, and the receiving grooves 221 on each support beam 2 correspond to each other, that is, the receiving grooves 221 at different positions on each support beam 2 are all located on the same straight line, so that the frame of the photovoltaic module can be embedded in the receiving grooves 221 of multiple support beams 2.

[0046] In this way, when the photovoltaic module is fixed to the mounting bracket, the frame of the photovoltaic module is placed in the corresponding receiving groove 221. At this time, the distance between the photovoltaic glass and the upper surface of the support beam 2 is reduced. When the photovoltaic glass is subjected to mechanical load, the pressure can be directly transmitted to the upper surface of the support beam 2 and the base 1, thereby reducing the deformation of the photovoltaic glass, and further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0047] Of course, it is understandable that when the depth of the accommodating groove 221 is equal to the distance between the back of the photovoltaic glass and the bottom of the frame, after the photovoltaic module is installed, the back of the photovoltaic glass contacts the upper surface of the support beam 2, which can maximize the support effect.

[0048] Reference Figure 2 A plurality of through holes 211 are provided on the bottom wall 21 along the extension direction of the support beam 2. 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 of the support beam 2 and reducing the corrosion of the support beam 2 by rainwater.

[0049] It should be noted that, although the cross-section of the support beam 2 is U-shaped in the above embodiment of the present application, it is taken as an example for illustrative description, but it does not constitute a limitation to the present application. For example, when the support beam 2 is a solid component with a polygonal cross-section, a receiving groove can also be provided on the support beam 2, so that the frame of the photovoltaic module is embedded in the receiving groove to support the photovoltaic glass.

[0050] As an optional implementation of the present application, at least one side wall 22 of the support beam 2 is connected to a support plate at one end away from the bottom wall 21, and the support plate has a working surface for supporting the photovoltaic glass. It should be noted that the "at least one side wall 22" mentioned above means that, in some embodiments, both side walls 22 of each support beam 2 are connected to a support plate, and in other embodiments, only one of the side walls of the support beam 2 is connected to a support plate.

[0051] Reference Figure 4 In one embodiment of the present application, support plates are connected to the two side walls 22 of each support beam 2. For the convenience of distinction, the support plate is called a first support plate 31. The extension direction of the first support plate 31 is consistent with the extension direction of the support beam 2. At this time, the two first support plates 31 can effectively support the photovoltaic glass.

[0052] Reference Figure 5 In another embodiment of the present application, the support plate is a second support plate 32 connected between the side walls 22 of adjacent support beams 2 that are opposite to each other. At this time, the extension direction of the second support plate 32 is set at an angle to the extension direction of the support beam 2. According to actual needs, the extension direction of the second support plate 32 can be perpendicular to the support beam 2, or can be inclined relative to the extension direction of the support beam 2, and the present application does not limit this.

[0053] In addition, it should be noted that the number of second support plates 32 between two adjacent support beams 2 is not limited to one, and multiple second support plates 32 can be provided according to actual needs. The shape of the second support plate 32 is also not limited to extending along a fixed direction, that is, being arranged in a straight line, and the second support plate 32 can also include two cross-arranged support portions, for example, being arranged in an "X" shape. The above deformations made to the shape or relative position of the second support plate 32 should all be within the protection scope of this application.

[0054] The second support plate 32 is connected between adjacent support beams 2, and its contact area with the photovoltaic glass is larger. In addition, the more the second support plates 32 are and the more their arrangements are, the more uniform the distribution of the support points of the photovoltaic glass is. In this way, each position of the photovoltaic glass can be effectively supported, thereby further reducing the probability of explosion or hidden cracks in the photovoltaic glass.

[0055] The present application also discloses a photovoltaic system, which includes the mounting bracket and the photovoltaic module in any of the above embodiments, wherein the frame of the photovoltaic module is connected to the support beam 2 , and the frame is embedded in the receiving groove 221 .

[0056] As an implementation method of the photovoltaic system of the present application, the depth of the receiving groove 221 is set to be greater than or equal to the distance between the bottom surface of the frame and the back surface of the photovoltaic glass. In this way, when the frame is embedded in the receiving groove 221, the photovoltaic glass can fit with the support beam 2, so that when the photovoltaic glass is subjected to pressure, the deformation of the photovoltaic glass can be minimized.

[0057] Further, refer to Figure 6 , the size of the receiving groove 221 in the extension direction of the support beam is greater than twice the width of the bottom of the frame of the photovoltaic module. In practical applications, the size of a single photovoltaic module is usually fixed, and multiple photovoltaic modules often need to be installed on a mounting bracket. At this time, through the above-mentioned setting, in the installation of the photovoltaic module, the parts of the frames of two adjacent photovoltaic modules that are opposite to each other can be located in the same receiving groove 221. In this way, in terms of spatial arrangement, adjacent photovoltaic modules can be closely arranged, reducing the gap between adjacent photovoltaic modules. In this way, the space utilization rate and the utilization rate of the mounting bracket can be improved. On the other hand, the number of receiving grooves 221 opened can also be reduced, thereby simplifying the processing technology of the mounting bracket.

[0058] 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.
