Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0049] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0050] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0051] With the development of photovoltaic power generation technology, the construction of photovoltaic power stations is growing rapidly, and the demand for fixed supports is also increasing day by day.

[0052] As mentioned in the background section, fixed brackets are one of the most commonly used photovoltaic array brackets in photovoltaic power generation systems. These brackets are stable and highly reliable, and are widely used in the construction of photovoltaic power plants.

[0053] In existing technologies, ground-mounted photovoltaic (PV) power stations typically use fixed supports composed of purlins, diagonal beams, columns, and braces. Whether a double-column or single-column structure, these supports utilize multiple support units composed of diagonal beams, columns, and braces to support the purlins, which in turn support the PV modules. However, this type of support system has numerous components, connectors, and fasteners, making installation cumbersome and hindering product standardization.

[0054] In view of this, please refer to Figures 1-12 The photovoltaic fixing bracket 1000 provided in the embodiments of this utility model can solve this problem, and will be described in detail below.

[0055] Please refer to Figure 1 This utility model provides a photovoltaic mounting bracket 1000, which includes a column 100, a main beam support 200, a main beam 300, and purlins 400. The main beam support 200 is connected to the top of the column 100, the main beam 300 is disposed on the main beam support 200, and the purlins 400 are connected to the main beam 300. The purlins 400 are used to connect the photovoltaic module 10. The main beam support 200 is installed on the top of the column 100, and then the main beam 300 is disposed on the main beam support 200, while the purlins 400 are connected to the main beam 300. The photovoltaic module 10 is connected to the purlins 400, thus completing the installation of the photovoltaic module 10.

[0056] As can be seen, the main beam 300 of the photovoltaic mounting bracket 1000 is directly fixed to the column 100 through the main beam support 200 (which can be understood as an adapter), and the photovoltaic module 10 is directly fixed to the main beam 300 through the purlin 400. The structure is simple, with few parts and adapters, and the corresponding number of fasteners required is small, making installation convenient.

[0057] It should be noted that the top of column 100 here can be understood as the upper end of column 100 when it is installed on the ground. Column 100 can be a C-shaped steel structure. Figure 2 As shown), or, in other embodiments, it may be as follows: Figure 3 The H-shaped steel structure shown.

[0058] The main beam support member 200 and the column 100 can both be multiple, with multiple main beam support members 200 and multiple columns 100 corresponding one-to-one, multiple columns 100 distributed at intervals, and multiple main beam support members 200 connected to the same main beam 300.

[0059] The word "multiple" here can be understood as at least two, for example, the number of beam supports and the number of columns 100 are two, three, four or five, etc.

[0060] In addition, there can be multiple purlins 400. The photovoltaic mounting bracket 1000 also includes multiple U-bolts. The multiple U-bolts and multiple purlins 400 can correspond one-to-one. The purlins 400 are fixed to the main beam 300 by the U-bolts, and the photovoltaic modules 10 are installed on the purlins 400 by fasteners.

[0061] To facilitate the tilting of the photovoltaic module 10 (which can be understood as tilting relative to the horizontal plane), the main beam support 200 is provided with a limiting groove 210. The main beam 300 passes through the limiting groove 210. The limiting groove 210 is a U-shaped groove. The extension direction from the groove opening 211 to the groove bottom 212 of the limiting groove 210 is inclined to the horizontal plane. At the same time, the main beam 300 is a rectangular beam (equivalent to a rectangular tube). The main beam 300 fits into the limiting groove 210, and the purlin 400 is in a tilted state (this tilted state can also be understood as tilting relative to the horizontal plane).

[0062] Of course, in other embodiments, the main beam 300 can also be a square tube or a polygonal tube (e.g., a triangular tube, a pentagonal tube, etc.).

[0063] In addition, please refer to Figure 5 and combined Figure 1 The photovoltaic mounting bracket 1000 also includes a pressure plate 500. There are multiple pressure plates 500. Each pressure plate 500 and each main beam support 200 are connected by fasteners. The inner walls of the limiting grooves 210 of the pressure plate 500 and the main beam support 200 together define a limiting channel. The main beam 300 passes through the limiting channel.

[0064] Please continue to refer to this. Figures 2-4 In order to facilitate the adjustment of the installation angle of the photovoltaic module 10, in this embodiment, the photovoltaic fixing bracket 1000 also includes a first fastener, the main beam support 200 is provided with a plurality of first angle adjustment holes 201 distributed in an arc shape, and the column 100 is provided with a plurality of second angle adjustment holes 101 distributed in an arc shape.

[0065] The first fastener can be a connecting bolt, and there can be multiple first fasteners, such as two or more.

[0066] Each first fastener is simultaneously inserted into one of the first angle adjustment holes 201 and a corresponding second angle adjustment hole 101 to connect the main beam support 200 and the column 100. By adjusting the relative positions of the main beam support 200 and the column 100, the correspondence between the first angle adjustment hole 201 and the second angle adjustment hole 101 can be changed.

[0067] In other words, the angle of the extension direction of the groove opening 211 to the bottom 212 of the groove 210 relative to the horizontal plane can be changed, thereby adjusting the angle of the side wall of the main beam 300 used to connect the purlin 400 relative to the horizontal plane. The tilt angle of the purlin 400 changes, making it possible to adjust the installation angle of the photovoltaic module 10.

[0068] In this embodiment, the number of first angle adjustment holes 201 is greater than the number of second angle adjustment holes 101, and the central angle of an adjacent second angle adjustment hole 101 is a non-integer multiple of the central angle of an adjacent first angle adjustment hole 201. Here, the non-integer multiple can be 1.5 times.

[0069] For example, the central angle of the adjacent second angle adjustment hole 101 is 3A, and the central angle of the adjacent first angle adjustment hole 201 is 2A. At this time, the tilt angle of the photovoltaic module 10 with a central angle of A can be adjusted. Meanwhile, the spacing between the adjacent second angle adjustment holes 101 and the spacing between the adjacent first angle adjustment holes 201 will not be too small, ensuring the structural strength at the connection between the column 100 and the main beam support 200.

[0070] Of course, in other embodiments, the central angle of an adjacent first angle adjustment hole 201 can be a non-integer multiple (e.g., 1.5 times) of the central angle of an adjacent second angle adjustment hole 101. The number of second angle adjustment holes 101 can be greater than the number of first angle adjustment holes 201. In this case, the angle of the central angle of an adjacent first angle adjustment hole 201 is 3A, and the angle of the central angle of an adjacent second angle adjustment hole 101 is 2A. In this case, the tilt angle adjustment of the photovoltaic module 10 with a central angle of A can also be achieved. At the same time, the spacing between adjacent second angle adjustment holes 101 and adjacent first angle adjustment holes 201 will not be too small, ensuring the structural strength at the connection between the column 100 and the main beam support 200.

[0071] It should be noted that, in some embodiments, when the installation tilt angle of the photovoltaic module 10 is determined, in order to facilitate the adjustment of the height of the photovoltaic module 10, the photovoltaic fixing bracket 1000 also includes a second fastener. The main beam support member 200 is provided with at least two first mounting holes, wherein the height of at least one first mounting hole is greater than the height of the other first mounting holes. The column 100 is provided with a first connecting hole. The second fastener passes through both the first connecting hole and one of the first mounting holes to connect the main beam support member 200 and the column 100.

[0072] Specifically, the number of first mounting holes can be two, three, or four, etc.

[0073] For example, if there are two first mounting holes, and the height of one first mounting hole is greater than the height of the other first mounting hole, the second fastener can be inserted into the first connecting hole and different first mounting holes simultaneously to adjust the height of the main beam support 200, thereby adjusting the height of the main beam 300 and achieving fine-tuning of the height of the photovoltaic module 10.

[0074] For example, if there are three first mounting holes, the height of one of the first mounting holes is greater than the height of the other two first mounting holes. The height of the other first mounting holes can also be different. In this case, the second fastener can adjust the height of the main beam support 200 by passing through the first connecting hole and different first mounting holes at the same time, thereby adjusting the height of the main beam 300 and achieving fine adjustment of the height of the photovoltaic module 10.

[0075] In some embodiments, the photovoltaic mounting bracket 1000 may also include a third fastener, the column 100 may be provided with at least two second mounting holes, wherein the height of at least one second mounting hole is greater than the height of the other second mounting holes, the main beam support 200 may be provided with a second connecting hole, and the third fastener may pass through both the second connecting hole and one of the second mounting holes to connect the main beam support 200 and the column 100.

[0076] Specifically, the number of second mounting holes can also be two, three, or four, etc.

[0077] For example, if there are two second mounting holes, and the height of one second mounting hole is greater than the height of the other second mounting hole, the third fastener can be inserted into the second connecting hole and different second mounting holes simultaneously to adjust the height of the main beam support 200, thereby adjusting the height of the main beam 300 and achieving fine-tuning of the height of the photovoltaic module 10.

[0078] For example, if there are three second mounting holes, the height of one of the second mounting holes may be greater than the height of the other two second mounting holes. The height of the other second mounting holes may also be different. In this case, the third fastener can adjust the height of the main beam support 200 by passing through the second connecting hole and the different second mounting holes simultaneously, thereby adjusting the height of the main beam 300 and achieving fine adjustment of the height of the photovoltaic module 10.

[0079] Please refer to Figure 7 and Figure 8In some embodiments, when the installation tilt angle of the photovoltaic module 10 is determined, in order to facilitate the adjustment of the height of the photovoltaic module 10, the photovoltaic fixing bracket 1000 further includes a fourth fastener. The main beam support 200 is provided with a first height adjustment hole 202, which has at least two first hole positions 2021, wherein the height of at least one first hole position 2021 is greater than the height of the other first hole positions 2021. The column 100 is provided with a third connecting hole 102. The fourth fastener passes through both the third connecting hole 102 and one of the first hole positions 2021 to connect the main beam support 200 and the column 100.

[0080] Specifically, the number of first holes 2021 can be two, three, or four, etc. The number of first height adjustment holes 202 and the number of third connecting holes 102 can both be multiple. Each first height adjustment hole 202 is a through hole with multiple first holes 2021.

[0081] Multiple first height adjustment holes 202 and multiple third connection holes 102 correspond one-to-one, and there are also multiple fourth fasteners, with multiple fourth fasteners and multiple third connection holes 102 corresponding one-to-one.

[0082] For example, if there are two first holes 2021, and the height of one first hole 2021 is greater than the height of the other first hole 2021, the fourth fastener can adjust the height of the main beam support 200 by simultaneously passing through the third connecting hole 102 and different first holes 2021, thereby adjusting the height of the main beam 300 and achieving fine adjustment of the height of the photovoltaic module 10.

[0083] For example, if there are three first holes 2021, and the height of one of the first holes 2021 is greater than the height of the other two first holes 2021, and the heights of these other first holes 2021 are different, then the fourth fastener can adjust the height of the main beam support 200 by simultaneously passing through the third connecting hole 102 and the different first holes 2021, thereby adjusting the height of the main beam 300 and achieving fine-tuning of the height of the photovoltaic module 10.

[0084] Of course, in some embodiments, the photovoltaic mounting bracket 1000 may also include a fifth fastener, the main beam support 200 is provided with a second height adjustment hole, the second height adjustment hole has at least two second holes, wherein the height of at least one second hole is greater than the height of the other second holes, the column 100 is provided with a fourth connecting hole, and the fifth fastener passes through both the fourth connecting hole and one of the second holes to connect the main beam support 200 and the column 100.

[0085] Specifically, the number of second holes can be two, three, or four, and the number of second height adjustment holes and fourth connecting holes can both be multiple. Each second height adjustment hole is a through hole with multiple second holes.

[0086] Multiple second height adjustment holes and multiple fourth connection holes correspond one-to-one, and there are also multiple fifth fasteners, with multiple fifth fasteners and multiple fourth connection holes corresponding one-to-one.

[0087] For example, if there are two second holes, and the height of one second hole is greater than the height of the other second hole, the fifth fastener can adjust the height of the main beam support 200 by simultaneously passing through the fourth connecting hole and different second holes, thereby adjusting the height of the main beam 300 and achieving fine-tuning of the height of the photovoltaic module 10.

[0088] For example, if there are three second holes, and the height of one of the second holes is greater than the height of the other two second holes, and the heights of these other second holes are different, then the fifth fastener can adjust the height of the main beam support 200 by simultaneously passing through the fourth connecting hole and the different second holes, thereby adjusting the height of the main beam 300 and achieving fine-tuning of the height of the photovoltaic module 10.

[0089] Please refer to Figure 9 and Figure 10 In some embodiments, when the main beam 300 is not installed horizontally, that is, when the main beam 300 is inclined relative to the horizontal plane, in order to facilitate the installation of the main beam 300, the main beam support 200 is rotatably connected to the top of the column 100, and the rotation axis of the main beam support 200 is perpendicular to the extension direction of the main beam 300.

[0090] The main beam support 200 is provided with two spaced-apart first rotating connection holes 203, and the column 100 is provided with two spaced-apart second rotating connection holes 103. The two first rotating connection holes 203 correspond to the two second rotating connection holes 103 respectively. The photovoltaic fixing bracket 1000 may also include a sixth fastener (not shown in the figure), which can connect the two first rotating connection holes 203 and the two second rotating connection holes 103. This allows the main beam support 200 and the column 100 to be fixed when the main beam support 200 rotates relative to the column 100 to a certain angle. This can effectively address the problem of effective connection between the column 100 and the main beam 300 caused by the tilt of the main beam 300.

[0091] In addition, it should be noted that Figure 1 The purlin 400 in the text can be understood as the first type of purlin 400 ( Figure 6As shown), the purlin 400 has a U-shaped structure (i.e., has a U-shaped groove). Optionally, in other embodiments, the purlin 400 may also be as shown... Figure 11 The zigzag structure shown indicates that the purlin 400 can be understood as a second type of purlin 400, or, as... Figure 12 The purlin 400 shown also has a U-shaped structure (i.e., it has a U-shaped groove). This purlin 400 can be understood as a third type of purlin 400. The difference between the third type of purlin 400 and the first type of purlin 400 is that the distance between the parallel inner walls of the U-shaped groove of the third type of purlin 400 is less than the distance from the bottom of the U-shaped groove to the opening of the U-shaped groove of the purlin 400, while the distance between the parallel inner walls of the U-shaped groove of the first type of purlin 400 is greater than the distance from the bottom of the U-shaped groove to the opening of the U-shaped groove of the purlin 400.

[0092] In summary, the photovoltaic mounting bracket 1000 includes a column 100, a main beam support 200, a main beam 300, and purlins 400. The main beam support 200 is connected to the top of the column 100. The main beam 300 is mounted on the main beam support 200. The purlins 400 are connected to the main beam 300 and are used to connect the photovoltaic modules 10. The aforementioned first, second, third, fourth, fifth, and sixth fasteners and U-bolts are also included. All of these can be understood as fasteners. It can be seen that a main beam 300 can be supported by multiple columns 100. The main beam support 200 is installed on the top of the column 100. Then, the main beam 300 is placed on the main beam support 200 and the main beam 300 is firmly fixed to the top of the column 100 with the pressure plate 500 and fasteners. The purlin 400 is fixed to the main beam 300 with U-bolts. The photovoltaic module 10 is installed on the purlin 400 with fasteners, thus completing the installation of the photovoltaic module 10.

[0093] The main beam 300 of the photovoltaic mounting bracket 1000 is directly fixed to the column 100 via the main beam support 200 (which can be understood as an adapter). The photovoltaic module 10 is directly fixed to the main beam 300 via the purlin 400. In other words, the photovoltaic mounting bracket 1000 can be composed of the column 100, the main beam 300, the main beam support 200, the pressure plate 500, the purlin 400 and fasteners. It has only one adapter, which makes the structure simple, with fewer parts and fewer adapters. The corresponding number of fasteners required is small, the installation is convenient, and each component is easy to standardize.

[0094] The photovoltaic mounting bracket 1000 abandons the existing structure of inclined beams, columns 100 and diagonal braces. Instead, it adopts a main beam 300 and column 100 as the main structure. The column 100 supports the main beam 300, and the photovoltaic modules 10 are installed on the main beam 300 through purlins 400. The structure is simple, with fewer connecting parts and fasteners, and it is easy to achieve standardized production. The photovoltaic mounting bracket 1000 has a very broad application prospect in the construction of photovoltaic power plants.

[0095] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
