Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to an installation structure and photovoltaic bracket. Background Technology

[0002] Photovoltaic modules convert solar energy into electrical energy to power loads or store it in batteries, making them the core component of a photovoltaic power generation system. Photovoltaic modules are typically mounted on rooftops, ground surfaces, or water surfaces using photovoltaic brackets to ensure stable operation.

[0003] Besides the stability of photovoltaic (PV) module power generation, the stability of PV module installation is also crucial. Furthermore, with the application of large-size PV modules that offer high power and high output, the requirements for PV module reliability are increasing.

[0004] The purlin system can fix the photovoltaic modules to the main beam of the photovoltaic bracket, but the current load-bearing capacity of the purlin system is insufficient to support the application of high-power photovoltaic modules. Utility Model Content

[0005] Based on this, this application provides an installation structure and a photovoltaic bracket to enhance the load-bearing capacity of the installation structure.

[0006] In a first aspect, this application provides an installation structure for mounting photovoltaic modules on a supporting structure, the installation structure comprising:

[0007] The purlin has a first side and a second side, the first side is used to connect the photovoltaic module, and the second side is provided with a first mating surface;

[0008] The first connector has a first end and a second end. The first connector abuts against the load-bearing structure through the first end. The second end is provided with a second mating surface that abuts against the first mating surface. The first mating surface is provided with a first recess and / or a first protrusion. The second mating surface is provided with a second protrusion that mates with the first recess and / or a second recess that mates with the first protrusion.

[0009] In one embodiment, the first mating surface has two first connecting holes, and the second mating surface has two second connecting holes that correspond one-to-one with each of the first connecting holes.

[0010] The mounting structure also includes fastening connectors, which include a first connecting structure and a second connecting structure. One end of the first connecting structure passes through one of the first connecting holes and a corresponding second connecting hole, and one end of the second connecting structure passes through another first connecting hole and a corresponding second connecting hole, so as to connect the purlin and the first connector.

[0011] In one embodiment, the mounting structure further includes a second connector, which is disposed opposite to the first connector. The second connector has two third connecting holes. The other end of the first connector passes through one of the third connecting holes, and the other end of the second connector passes through the other third connecting hole to connect the second connector, the first connector, and the purlin.

[0012] In one embodiment, the purlin includes a first bottom surface and two first sidewalls connected to opposite sides of the first bottom surface, and a first mating surface is disposed on the first bottom surface;

[0013] The fastening connector also includes a third connecting structure, the two opposite ends of which are connected to the first connecting structure and the second connecting structure respectively, and the third connecting structure extends into the space enclosed by the first bottom surface and the two first side walls.

[0014] In one embodiment, the third connecting structure is provided with a third protrusion that mates with the first recess and / or a third recess that mates with the first protrusion.

[0015] In one embodiment, the mounting structure further includes two fasteners, one of which is installed on one end of the first connecting structure that passes through the third connecting hole and abuts against the side of the second connector opposite to the first connector, and the other fastener is installed on one end of the second connecting structure that passes through the third connecting hole and abuts against the side of the second connector opposite to the first connector.

[0016] In one embodiment, the fastener is a flange nut.

[0017] In one embodiment, the first protrusion includes at least two first sub-protrusions, and the second recess includes a first sub-groove that corresponds to and mates with each of the first sub-protrusions; and / or,

[0018] The first recess includes at least two second sub-grooves, and the second protrusion includes a second sub-protrusion that corresponds to and engages with each of the second sub-grooves.

[0019] In one embodiment, the first connector abuts against the sidewall of the load-bearing structure via a second end, the second end having a fourth recess that matches the shape of the sidewall of the load-bearing structure.

[0020] Secondly, this application provides a photovoltaic support structure, which includes a load-bearing structure and an installation structure described in the above embodiments. The photovoltaic modules are installed on the load-bearing structure through the installation structure.

[0021] The aforementioned mounting structure and photovoltaic bracket include purlins and a first connector. Photovoltaic modules are mounted using the mating purlins and first connector, which reduces costs and increases the load-bearing capacity of the mounting structure. The purlin abuts against the second mating surface of the first connector via a first mating surface, and the purlin and first connector can contact each other using mating protrusions and recesses, increasing the contact area between them. This further enhances the load-bearing capacity and stability of the mounting structure, enabling it to support high-power, large-size photovoltaic modules and expanding its applicability. Furthermore, the increased contact area between the purlin and the first connector allows for a reduction in purlin thickness, thus lowering costs. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0036] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] With fossil fuels becoming increasingly scarce, renewable energy has become an important part of energy use. Solar energy, which is relatively easier to obtain, has seen particularly rapid development in recent years.

[0041] The application of high-efficiency, high-power photovoltaic (PV) modules is one of the key factors in reducing the levelized cost of electricity (LCOE) of PV power generation. Currently, the proportion of 210mm cells and 600W+ modules is rapidly expanding, and at the same time, the requirements for the reliability of PV products are also increasing. Besides the stability of PV module power generation, the stability of its installation structure is also crucial. The purlin system, which fixes the PV modules to the main beam of the support frame, has become a key research focus.

[0042] For high-power, large-size modules, failures occurred in all current purlin systems during the verification process according to the IEC 61215-2:2016 load test standard. This indicates that the strength and stiffness of the current purlin system are insufficient to support the application of high-power modules.

Figure 3 This is an assembly front view of the installation structure provided in an embodiment of this application.

Figure 5 This is a schematic diagram of the purlin structure provided in an embodiment of this application. Figure 6 A side view of a purlin provided in an embodiment of this application. Figure 7 This is a schematic diagram of the structure of the first connector provided in an embodiment of this application. Figure 8 A side view of the first connector provided in an embodiment of this application.

[0044] See Figures 1-8 One embodiment of this application provides an installation structure for mounting photovoltaic modules on a support structure 10. The installation structure includes: a purlin 20 having a first side and a second side, the first side being used to connect the photovoltaic modules, and the second side having a first mating surface 21; a first connector 30 having a first end and a second end, the first connector 30 abutting against the support structure 10 through the first end, and the second end having a second mating surface 31 abutting against the first mating surface 21. The first mating surface 21 is provided with a first recess 22 and / or a first protrusion, and the second mating surface 31 is provided with a second protrusion 32 that mates with the first recess 22 and / or a second recess that mates with the first protrusion.

[0045] As can be seen from the composition of the above installation structure, combined with Figures 1-8 The photovoltaic module can be installed on one side of the purlin 20, and the other side of the purlin 20 abuts against one end of the first connector 30. The other end of the first connector 30 can abut against the supporting structure 10, thus enabling the photovoltaic module to be installed on the supporting structure 10 through the purlin 20 and the first connector 30. If the height of the purlin 20 is too low, the glass of the photovoltaic module may be damaged when subjected to large wind pressure. If the height of the purlin 20 is too high, it will lead to a surge in cost. Therefore, installing the photovoltaic module through the matching purlin 20 and the first connector 30 can reduce costs, improve the load-bearing capacity of the installation structure, and enhance the wind resistance of the photovoltaic module.

[0046] Furthermore, the purlin 20 abuts against the second mating surface 31 of the first connector 30 via the first mating surface 21. The first mating surface 21 is provided with a first recess 22 and / or a first protrusion, and the second mating surface 31 is provided with a second protrusion 32 that mates with the first recess 22 and / or a second recess that mates with the first protrusion. This allows the purlin 20 and the first connector 30 to contact each other through the mating protrusions and recesses, increasing the contact area between them. This further improves the load-bearing capacity and stability of the mounting structure, enabling it to support high-power, large-size photovoltaic modules and expanding its applicability to meet diverse needs. In addition, the increased contact area between the purlin 20 and the first connector 30 allows for a reduction in the thickness of the purlin 20, thus reducing costs.

[0047] In some examples, the first mating surface 21 may be provided with a first protrusion, and the second mating surface 31 may be provided with a second recess that mates with the first protrusion; alternatively, the first mating surface 21 may be provided with a first recess 22, and the second mating surface 31 may be provided with a second protrusion 32 that mates with the first recess 22; or alternatively, the first mating surface 21 may be provided with a first recess 22 and a first protrusion, and the second mating surface 31 may be provided with a second recess that mates with the first protrusion and a second protrusion 32 that mates with the first recess 22.

[0048] Among them, Figures 1-3 As shown, the second protrusion 32 and the first concave portion 22 are matched, meaning that the shapes of the second protrusion 32 and the first concave portion 22 are matched; the second concave portion and the first protrusion are matched, meaning that the shapes of the second concave portion and the first protrusion are matched.

[0049] In some examples, the first recess 22 may include a first arcuate recess, and the second protrusion 32 may include a first arcuate protrusion that matches the shape of the first arcuate recess; and / or, the first protrusion may include a second arcuate protrusion, and the second recess may include a second arcuate recess that matches the shape of the first arcuate protrusion. In this case, the purlin 20 can contact the first connector 30 through the matching arcuate recess and arcuate protrusion, increasing the contact area between the purlin 20 and the first connector 30 and improving the load-bearing capacity of the installation structure.

[0050] In some examples, the first protrusion may include at least two first sub-protrusions, and the second recess may include a first sub-groove that corresponds to each of the first sub-protrusions; and / or, the first recess 22 may include at least two second sub-grooves, and the second protrusion 32 may include a second sub-protrusion that corresponds to each of the second sub-grooves.

[0051] In this configuration, the first sub-groove and the first sub-protrusion are matched one-to-one, meaning that the number of first sub-grooves and the first sub-protrusions are the same and their shapes match. Similarly, the second sub-protrusion and the second sub-groove are matched one-to-one, meaning that the number of second sub-grooves and the second sub-protrusions are the same and their shapes match. At this point, the purlin 20 can contact the first connector 30 through at least two first sub-protrusions and first sub-grooves with matching shapes, and / or at least two second sub-grooves and second sub-protrusions with matching shapes, thereby increasing the contact area between the purlin 20 and the first connector 30 and improving the load-bearing capacity of the installation structure.

[0052] For example, compared to the arc-shaped concave portion and the arc-shaped convex portion, the sub-protrusions and sub-grooves are smaller in size and more numerous. Further, when the first convex portion includes the first sub-protrusion and the second concave portion includes the first sub-grooves, the first sub-protrusions can be evenly distributed on the first mating surface 21, and the first sub-grooves can be evenly distributed on the second mating surface 31; when the first concave portion 22 includes the second sub-grooves and the second convex portion 32 includes the second sub-protrusions, the second sub-grooves can be evenly distributed on the first mating surface 21, and the second sub-protrusions can be evenly distributed on the second mating surface 31.

[0053] In some examples, the first protrusion may include a first arcuate protrusion and at least two first sub-protrusions, and the second concave portion may include a second arcuate concave portion and at least two first sub-grooves. In this case, the first sub-protrusions are evenly distributed on the surface of the first arcuate protrusion, and the second sub-grooves are evenly distributed on the surface of the second arcuate concave portion; and / or, the first concave portion 22 may include a second arcuate concave portion and at least two second sub-grooves, and the second protrusion 32 may include a second arcuate protrusion and at least two second sub-protrusions. In this case, the second sub-grooves are evenly distributed on the surface of the second arcuate concave portion, and the second sub-protrusions are evenly distributed on the surface of the second arcuate protrusion.

[0054] For example, such as Figures 1-3 and Figures 5-8 As shown, the first mating surface 21 is provided with a first recess 22, and the second mating surface 31 is provided with a second protrusion 32 that mates with the first recess 22. The first recess 22 is an arc-shaped recess, and the second protrusion 32 is an arc-shaped protrusion that matches the shape of the first recess 22. Based on this, the purlin 20 and the first connector 30 contact each other through arc-shaped surfaces, which not only increases the contact area and enhances the load-bearing capacity of the installation structure, but also improves the load-bearing effect under torsion, further improving the stability of the installation structure. In addition, the process of forming the arc-shaped first recess 22 on the first mating surface 21 of the purlin 20 and the arc-shaped second protrusion 32 on the second mating surface 31 of the first connector 30 is simpler and easier to implement, which is conducive to the standardization of production, enables mass production, and reduces production costs.

[0055] For example, an arc-shaped first recess 22 can be formed on the first mating surface 21 of the purlin 20 and an arc-shaped second protrusion 32 can be formed on the second mating surface 31 of the first connector 30 using a stamping process.

[0056] Figure 9 This is a schematic diagram of a fastening connector provided in an embodiment of this application.

[0057] As one possible implementation method, combined Figures 1-9 The first mating surface 21 has two first connecting holes 23, and the second mating surface 31 has two second connecting holes 33 corresponding to each of the first connecting holes 23. The mounting structure also includes a fastening connector 40, which includes a first connecting structure 41 and a second connecting structure 42. One end of the first connecting structure 41 passes through one of the first connecting holes 23 and the corresponding second connecting hole 33, and one end of the second connecting structure 42 passes through the other first connecting hole 23 and the corresponding second connecting hole 33 to connect the purlin 20 and the first connector 30.

[0058] Based on this, combined Figures 1-9 The first connecting structure 41 can connect one of the first connecting holes 23 and the corresponding second connecting hole 33, and the second connecting structure 42 can connect the other first connecting hole 23 and the corresponding second connecting hole 33, so that the first mating surface 21 and the second mating surface 31 can fit tightly together, thereby realizing the connection between the purlin 20 and the first connecting member 30.

[0059] Figure 10 This is a schematic diagram of the structure of the second connector provided in an embodiment of this application.

[0060] In some examples, combined Figures 1-10 The installation structure also includes a second connector 50, which is disposed opposite to the first connector 30. The second connector 50 has two third connecting holes 51. The other end of the first connecting structure 41 passes through one of the third connecting holes 51, and the other end of the second connecting structure 42 passes through the other third connecting hole 51 to connect the second connector 50, the first connector 30 and the purlin 20.

[0061] Based on this, combined Figures 1-10 One end of the first connecting structure 41 passes through the first connecting hole 23 and the corresponding second connecting hole 33, and the other end passes through one of the third connecting holes 51. One end of the second connecting structure 42 passes through another first connecting hole 23 and the corresponding second connecting hole 33, and the other end passes through another third connecting hole 51, so that the first connecting structure 41 and the second connecting structure 42 can fasten the purlin 20, the first connecting member 30 and the second connecting member 50.

[0062] In some examples, combined Figures 1-3 , Figure 5 and Figure 7 The two first connecting holes 23 can be distributed at opposite ends of the first mating surface 21, and correspondingly, the two second connecting holes 33 can also be distributed at opposite ends of the second mating surface 31, and the two third connecting holes 51 can also be distributed on opposite sides of the second connector 50. At this time, the first connector 30, the first connecting structure 41, the second connecting structure 42, and the second connector 50 can form a limiting space for limiting and engaging the bearing structure 10.

[0063] For example, the first connecting structure 41 and the second connecting structure 42 can be bolts with threads at both ends. This is only an example and is not a specific limitation.

[0064] In some examples, such as Figure 9 As shown, the fastening connector 40 may further include a third connecting structure 43, the opposite ends of which are connected to the first connecting structure 41 and the second connecting structure 42, respectively. In this case, the fastening connector 40 includes a first connecting structure 41, a third connecting structure 43, and a second connecting structure 42 connected at their ends in sequence.

[0065] For example, Figure 9 As shown, when the first mating surface 21 is provided with a first recess 22 and the second mating surface 31 is provided with a second protrusion 32 that mates with the first recess 22, and the first recess 22 is an arc-shaped recess and the second protrusion 32 is an arc-shaped protrusion that matches the shape of the first recess 22, the fastening connector 40, which includes the first connecting structure 41, the third connecting structure 43 and the second connecting structure 42 connected at their ends in sequence, can be a U-bolt, and the ends of the first connecting structure 41 and the second connecting structure 42 away from the third connecting structure 43 have threads.

[0066] For example, the opposite ends of the third connecting structure 43 can be connected to the ends of the first connecting structure 41 and the second connecting structure 42 that are away from the first connecting hole 23 and the second connecting hole 33, respectively. In this case, the third connector can be limited from the side of the bearing structure 10 away from the first connector 30, and the first connector 30, the first connecting structure 41, the second connecting structure 42 and the third connecting structure 43 can form a limiting space for limiting and engaging the bearing structure 10.

[0067] In some examples, such as Figure 5 and Figure 6 As shown, the purlin 20 includes a first bottom surface 24 and two first sidewalls 25 connected to opposite sides of the first bottom surface 24, and a first mating surface 21 is provided on the first bottom surface 24.

[0068] For example, Figure 4 and Figure 9 As shown, the opposite ends of the third connecting structure 43 can be connected to one end of the first connecting structure 41 and the second connecting structure 42 that pass through the first connecting hole 23 and the second connecting hole 33, respectively. The third connecting structure 43 can extend into the space enclosed by the first bottom surface 24 and the two first sidewalls 25. At this time, the fastening connector 40 connects one of the first connecting holes 23 and its corresponding second connecting hole 33 through the connecting section between the third connecting structure 43 and the first connecting structure 41, and connects the other first connecting hole 23 and its corresponding second connecting hole 33 through the connecting section between the third connecting structure 43 and the first connecting structure 41. When the fastening connector 40 is a U-bolt, the purlin 20 and the first connector 30 can be tightly connected through the main body of the fastening connector 40, avoiding the problem that the nut cannot be locked when connecting the mating surfaces with concave and convex parts through the threaded connection position of the fastening connector 40, further improving the stability and load-bearing capacity of the installation structure.

[0069] Furthermore, such as Figure 4 and Figure 9 As shown, the third connecting structure 43 is provided with a third protrusion 431 that mates with the first recess 22 and / or a third recess that mates with the first protrusion.

[0070] Among them, such as Figure 4 and Figure 9 As shown, the third protrusion 431 mates with the first recess 22, meaning that the shapes of the third protrusion 431 and the first recess 22 match; the third recess mates with the first protrusion, meaning that the shapes of the third recess and the first protrusion match. Based on this, the third connecting structure 43 can achieve a tight fit with the first mating surface 21 with its protrusions and recesses of matching shapes, resulting in better stability and load-bearing capacity when subjected to wind loads from different directions, as well as wind pressure torque, further improving the load-bearing capacity and stability of the installation structure.

[0071] For example, the first mating surface 21 may be provided with a first protrusion, and the third connecting structure 43 may be provided with a third recess that mates with the first protrusion; or, the first mating surface 21 may be provided with a first recess 22, and the third connecting structure 43 may be provided with a third protrusion 431 that mates with the first recess 22; or, the first mating surface 21 may be provided with a first recess 22 and a first protrusion, and the third connecting structure 43 may be provided with a third recess that mates with the first protrusion and a third protrusion 431 that mates with the first recess 22.

[0072] For example, Figure 4 and Figure 9 As shown, when the first mating surface 21 is provided with the first recess 22, the third connecting structure 43 is provided with the third protrusion 431 that mates with the first recess 22.

[0073] In some examples, such as Figure 4 and Figure 5 As shown, the side of the first sidewall 25 away from the first bottom surface 24 has a bent portion 251, which can be threadedly connected to the frame 60 of the photovoltaic module to realize the installation of the photovoltaic module on the purlin 20.

[0074] As one possible implementation, such as Figure 4 As shown, the mounting structure also includes two fasteners 70. One fastener 70 is installed at one end of the first connecting structure 41 that passes through the third connecting hole 51 and abuts against the side of the second connecting member 50 opposite to the first connecting member 30. The other fastener 70 is installed at one end of the second connecting structure 42 that passes through the third connecting hole 51 and abuts against the side of the second connecting member 50 opposite to the first connecting member 30. Based on this, the first connecting structure 41 and the second connecting member 50, as well as the second connecting structure 42 and the second connecting member 50, can be locked by the fasteners 70, realizing the assembly of the purlin 20, the first connecting member 30, the fastening connecting member 40 and the second connecting member 50, thereby allowing the photovoltaic module to be installed onto the supporting structure 10 through the mounting structure.

[0075] In some examples, fastener 70 is a flange nut.

[0076] As the size of photovoltaic modules continues to change, it is currently necessary to install spring washers, gaskets, and nuts when fixing photovoltaic modules, which increases installation time and labor costs. Therefore, flange nuts can be used to connect and fasten the connector 40 and the second connector 50, eliminating the need for spring washers, gaskets, and nuts, saving installation time and labor costs, and promoting standardized on-site installation.

[0077] For example, the connection between the purlin 20 and the frame 60 of the photovoltaic module can also be made using flange nuts, which further reduces installation time and labor costs.

[0078] As one possible implementation, such as Figures 1-3 , Figure 7 and Figure 8 As shown, the first connector 30 abuts against the side wall of the supporting structure 10 at its second end, and the second end is provided with a fourth recess 34, which matches the shape of the side wall of the supporting structure 10. Based on this, the second end of the first connector 30 can fit tightly against the side wall of the supporting structure 10, further improving the load-bearing capacity and stability of the installation structure.

[0079] On the other hand, this application also provides a photovoltaic support structure, which includes a load-bearing structure 10 and an installation structure described in any of the above embodiments. The photovoltaic modules are installed on the load-bearing structure 10 through the installation structure.
