When the span of the photovoltaic support is large, additional stabilizing cables or anti-chord cables are usually added to improve the wind resistance of the photovoltaic system. However, once the wind load exceeds the design value of the photovoltaic system or there are defects in the construction process of the photovoltaic system, it can easily lead to hidden cracks in the photovoltaic modules or tearing and falling off of the frame, or even the collapse of the entire row of photovoltaic supports, resulting in significant losses.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] The following is for reference. Figures 1-8 A photovoltaic system 10 according to an embodiment of the present utility model is described.

[0033] like Figures 1-8 As shown, this application provides a photovoltaic system 10, including: a module cable 102; a plurality of photovoltaic modules 101, all of which are fixed to the module cable 102, each photovoltaic module 101 and the module cable 102 are arranged along a first direction, and some of the photovoltaic modules 101 are detachable photovoltaic modules 1012, which are configured to detach from the module cable 102 when subjected to a force along the first direction away from the module cable 102 that reaches a first preset force value.

[0034] In this embodiment, multiple photovoltaic modules 101 are fixed to module cables 102. In some embodiments of this application, multiple photovoltaic modules 101 can be fixed to module cables 102 via connecting brackets 100. In some embodiments of this application, multiple photovoltaic modules 101 can be fixed to module cables 102 via bolts. In some embodiments of this application, a portion of the multiple photovoltaic modules 101 is fixed to module cables 102 via connecting brackets 100, and another portion of the multiple photovoltaic modules 101 is fixed to module cables 102 via bolts.

[0035] Each photovoltaic module 101 and module cable 102 are arranged along a first direction, i.e., the first direction is... Figure 6 In the X direction, some of the multiple photovoltaic modules 101 are detachable photovoltaic modules 1012. When the detachable photovoltaic module 1012 is subjected to a force along the first direction away from the module cable 102, reaching a first preset force value, as an example: during a super typhoon, the detachable photovoltaic module 1012 is detached from the module cable 102 by the wind force, thereby actively unloading the photovoltaic support. This helps reduce the risk of wind force continuously being transmitted to the photovoltaic support through the detachable photovoltaic module 1012, thereby reducing the risk of major losses such as most photovoltaic modules 101 developing microcracks, frame 1011 tearing and falling off, or even the collapse of the entire row of photovoltaic supports. This helps improve the stability and safety of the photovoltaic system 10, reduces the economic losses caused by winds exceeding the design value, and acts as a "fuse".

[0036] Specifically, as some embodiments of this application, such as Figures 1-2 As shown, at least a portion of the photovoltaic modules 101 in the middle of the outer array of the photovoltaic support structure are unloadable photovoltaic modules 1012. Further, 10%-50% of the outer array of the photovoltaic support structure... Figure 1 , Figure 2The photovoltaic modules 101 in the framed portion are detachable photovoltaic modules 1012. For example, 10%, 20%, or 50% of the photovoltaic modules 101 in one span of the outer array of the photovoltaic support are detachable photovoltaic modules 1012, while the remaining photovoltaic modules 101 are non-detachable photovoltaic modules 1013. When the non-detachable photovoltaic modules 1013 are subjected to a force along the first direction away from the module cable 102 and the force reaches a first preset force value, the non-detachable photovoltaic modules 1013 will not detach from the module cable 102.

[0037] As some embodiments of this application, the detachable photovoltaic module 1012 is fixed to the module cable 102 by the connecting bracket 100, and the non-detachable photovoltaic module 1013 is also fixed to the module cable 102 by the connecting bracket 100. The connecting bracket 100 includes a clamping part 2, which includes a first clamping part 21 and a second clamping part 22. The first clamping part 21 and the second clamping part 22 are arranged opposite to each other to form a clamping space 23 between the first clamping part 21 and the second clamping part 22. The module cable 102 passes through the clamping space 23.

[0038] The load on the connecting bracket 100 that mates with the non-removable photovoltaic module 1013 when detached from the module cable 102 is much greater than the load on the connecting bracket 100 that mates with the removable photovoltaic module 1012 when detached from the module cable 102. For example, the thickness and width of the clamping portion 2 of the connecting bracket 100 that mates with the non-removable photovoltaic module 1013 can be increased. As some embodiments of this application, multiple photovoltaic modules 101 can be fixed to the module cable 102 by bolts.

[0039] As some embodiments of this application, the removable photovoltaic module 1012 is fixed to the module cable 102 via the connecting bracket 100, and the non-removable photovoltaic module 1013 is fixed to the module cable 102 via clamps, bolts, or clamps. As some embodiments of this application, the removable photovoltaic module 1012 and the non-removable photovoltaic module 1013 can also be connected using traditional module connectors, but the removable photovoltaic module 1012 uses bolts of a specific specification to ensure that the bolts can break under a set load (i.e., when the force on the removable photovoltaic module 1012 reaches a first preset force value). For example, the bolts of the removable photovoltaic module 1012 can be low-grade bolts, necking bolts, low-grade nuts, etc.

[0040] When the wind force is low, all photovoltaic modules 101 can be stably assembled on the module cable 102, and the photovoltaic system 10 operates normally. When the wind force is high, when the force exerted on the unloadable photovoltaic module 1012 by the wind and moves away from the module cable 102 in the first direction reaches a first preset force value F, the unloadable photovoltaic module 1012 detaches from the module cable 102 to actively unload the photovoltaic support, thereby reducing the natural frequency and amplitude of the photovoltaic support and the force exerted by the wind load. This reduces the risk of damage to the photovoltaic support due to wind speed exceeding the design value (such as super typhoons) or other construction defects, thus reducing the scale of economic losses. The non-unloadable photovoltaic module 1013 does not detach from the module cable 102 and continues to perform its function, realizing the function of the photovoltaic system 10 in converting solar energy into electrical energy.

[0041] Therefore, by configuring the unloadable photovoltaic module 1012 to detach from the module cable 102 when subjected to a first preset force value, the photovoltaic support can be actively unloaded, reducing the risk of major losses such as microcracks in most photovoltaic modules 101, tearing and falling off of the frame 1011, or even the collapse of the entire row of photovoltaic supports. This is beneficial to improving the stability and safety of the photovoltaic system 10, reducing the economic losses caused by winds exceeding the design value, and acting as a "fuse".

[0042] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, multiple photovoltaic modules 101 form multiple rows of photovoltaic modules 103, which are arranged sequentially along a second direction. Each row of photovoltaic modules 103 includes multiple photovoltaic modules 101, which are arranged along a third direction. The first direction, the second direction, and the third direction intersect each other. At least one row of photovoltaic modules 103 has a detachable photovoltaic module 1012.

[0043] Multiple photovoltaic modules 101 form multiple rows of photovoltaic module rows 103. For example, multiple photovoltaic modules 101 form two, ten, or more rows of photovoltaic module rows 103. The multiple rows of photovoltaic module rows 103 are arranged sequentially along a second direction, i.e., the second direction is... Figure 1 The Y direction. Each row of photovoltaic modules 103 includes multiple photovoltaic modules 101, for example: each row of photovoltaic modules 103 includes two, thirty, fifty or more photovoltaic modules 101. The multiple photovoltaic modules 101 in each row of photovoltaic modules 103 are arranged along a third direction, i.e. Figure 1The Z direction in the diagram. The first direction, the second direction, and the third direction intersect each other, that is, the X direction, the Y direction, and the Z direction intersect each other. This arrangement can make the arrangement of multiple photovoltaic modules 101 reasonable, and make the assembly of multiple photovoltaic modules 101 and module cables 102 reasonable, reducing the risk of interference between any two adjacent photovoltaic modules 101 and improving the rationality of the arrangement of photovoltaic modules 101.

[0044] At least one row of photovoltaic modules 103 has detachable photovoltaic modules 1012. For example, one row of photovoltaic modules 103, six rows of photovoltaic modules 103, or eight rows of photovoltaic modules 103 have detachable photovoltaic modules 1012. The detachable photovoltaic modules 1012 are all installed independently and have no structural connection with adjacent photovoltaic modules 101. When the wind is strong, the detachable photovoltaic modules 1012 will not affect adjacent photovoltaic modules 101 when they detach, reducing the economic losses caused by cascading damage.

[0045] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, the photovoltaic module 101 located in the middle of the photovoltaic module row 103 with the unloadable photovoltaic module 1012 is configured as the unloadable photovoltaic module 1012.

[0046] Among them, the photovoltaic module 101 located in the middle position is in the core area of ​​the photovoltaic module row 103 and will be subject to higher wind pressure and environmental stress. By constructing the photovoltaic module 101 located in the middle position of the photovoltaic module row 103 with unloadable photovoltaic module 1012 as an unloadable photovoltaic module 1012, the unloadable photovoltaic module 1012, which is subject to higher wind pressure and environmental stress, can be detached from the module cable 102 in time when the force reaches the first preset force value, thereby reducing the risk of major losses such as the collapse of the photovoltaic support in the middle position or even the collapse of the entire row of photovoltaic supports, which is conducive to improving the stability and safety of the photovoltaic system 10.

[0047] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, the multi-row photovoltaic module row 103 has one or more unloadable photovoltaic modules 1012, and each row of photovoltaic module row 103 with unloadable photovoltaic modules 1012 has multiple unloadable photovoltaic modules 1012. The unloadable photovoltaic modules 1012 in two adjacent rows of photovoltaic module rows 103 are opposite each other along a second direction.

[0048] Among them, the multi-row photovoltaic module row 103 has unloadable photovoltaic modules 1012. When a super typhoon occurs, the unloadable photovoltaic modules 1012 are detached from the module cable 102 by the wind force, thereby actively unloading the photovoltaic support. This helps to reduce the risk of wind force being continuously transmitted to the photovoltaic support through the unloadable photovoltaic modules 1012, thereby reducing the risk of major losses such as most photovoltaic modules 101 developing microcracks, frame 1011 tearing and falling off, or even the collapse of the entire row of photovoltaic supports. This helps to improve the stability and safety of the photovoltaic system 10, reduce the economic losses caused by winds exceeding the design value, and act as a "fuse".

[0049] Each row of photovoltaic modules 103 having a removable photovoltaic module 1012 has one or more removable photovoltaic modules 1012. For example, each row of photovoltaic modules 103 having a removable photovoltaic module 1012 has one, two, three, or more removable photovoltaic modules 1012, and the removable photovoltaic modules 1012 in two adjacent rows of photovoltaic modules 103 are opposite each other along a second direction. Further, as some embodiments of this application, along the second direction, such as... Figure 1 As shown, the number of unloadable photovoltaic modules 1012 in the photovoltaic module row 103 can be equal in each row. As some embodiments of this application, such as... Figure 2 As shown, along the second direction, from the outer photovoltaic module row 103 to the inner photovoltaic module row 103, the number of unloadable photovoltaic modules 1012 in the photovoltaic module row 103 can decrease sequentially. This arrangement makes the arrangement of unloadable photovoltaic modules 1012 reasonable, which is conducive to the number of unloadable photovoltaic modules 1012 on the periphery being greater than the number on the inner side. This reduces the risk that unloadable photovoltaic modules 1012 will damage other non-unloadable photovoltaic modules 1013 after detaching from the module cable 102, and further improves the stability and safety of the photovoltaic system 10.

[0050] According to one embodiment of this application, the photovoltaic system 10 may further include: a fastener (not shown in the figure), wherein the detachable photovoltaic module 1012 is fixed to the module cable 102 by the fastener, and the fastener is configured to cause the detachable photovoltaic module 1012 to detach from the module cable 102 when the force on the detachable photovoltaic module 1012 reaches a first preset force value.

[0051] The detachable photovoltaic module 1012 can be fixed to the module cable 102 by fasteners, which can be, but are not limited to, low-grade bolts, necking bolts, low-grade nuts, etc. The non-detachable photovoltaic module 1013 is rigidly connected to the module cable 102. The fasteners are configured to cause the detachable photovoltaic module 1012 to detach from the module cable 102 when the force on the detachable photovoltaic module 1012 reaches a first preset force value. For example, when the wind force is strong, the detachable photovoltaic module 1012 will be subjected to the first preset force value. At this time, the fastener will break or come off, so that the detachable photovoltaic module 1012 will detach from the module cable 102 and actively unload the photovoltaic support, thereby reducing the natural frequency, amplitude and force of the photovoltaic support from wind load, reducing the risk of damage to the photovoltaic support due to wind speed exceeding the design value (such as super typhoon) or other construction defects, and thus reducing the scale of economic loss.

[0052] According to one embodiment of this application, such as Figures 3-8 As shown, the photovoltaic system 10 also includes a connecting bracket 100, through which the detachable photovoltaic module 1012 is mounted on the module cable 102. The connecting bracket 100 includes a clamping part 2, which includes a first clamping part 21 and a second clamping part 22. The first clamping part 21 and the second clamping part 22 are arranged opposite to each other to form a clamping space 23 between the first clamping part 21 and the second clamping part 22. The module cable 102 passes through the clamping space 23. The first clamping part 21 and the second clamping part 22 are configured to move away from each other when a force along the arrangement direction of the first clamping part 21 and the second clamping part 22 reaches a second preset force value, so that the module cable 102 moves out of the clamping space 23.

[0053] The detachable photovoltaic module 1012 is fixedly connected to the connecting bracket 100, and the connecting bracket 100 is assembled to the module cable 102 so that the detachable photovoltaic module 1012 is installed on the module cable 102 through the connecting bracket 100. The connecting bracket 100 includes a clamping part 2, a first clamping part 21 and a second clamping part 22 are arranged opposite to each other to form a clamping space 23 between the first clamping part 21 and the second clamping part 22. The module cable 102 passes through the clamping space 23, and the shape of the clamping space 23 is adapted to the shape of the module cable 102 so that the connecting bracket 100 and the photovoltaic module 101 can be stably assembled on the module cable 102 when the module cable 102 passes through the clamping space 23.

[0054] When the force exerted on the first clamping part 21 and the second clamping part 22 along the arrangement direction of the first clamping part 21 and the second clamping part 22 reaches a second preset force value, as an example: during a super typhoon, the photovoltaic module 101 is subjected to wind force and transmits the force to the clamping part 2. Along the arrangement direction of the first clamping part 21 and the second clamping part 22, when the force exerted on the first clamping part 21 and the second clamping part 22 reaches the second preset force value, the first clamping part 21 and the second clamping part 22 move away from each other, so that the module cable 102 moves out of the clamping space 23. When the photovoltaic module 101 and the connecting bracket 100 detach from the module cable 102, the photovoltaic bracket is actively unloaded, which helps to reduce the risk of wind continuously being transmitted to the photovoltaic bracket through the photovoltaic module 101 and the connecting bracket 100. This reduces the risk of major losses such as microcracks in most photovoltaic modules 101, tearing and falling off of the frame 1011, or even the collapse of the entire row of photovoltaic brackets, thus reducing the scale of economic losses. It also helps to improve the stability and safety of the photovoltaic system 10, reduce the economic losses caused by winds exceeding the design value, and acts as a "fuse".

[0055] Specifically, the assembly ends of the first clamping part 21 and the second clamping part 22 are moved toward each other to open the clamping space 23. The module cable 102 is moved into the clamping space 23 through the open end. The end of the first clamping part 21 that is away from the fixing part 1 and the end of the second clamping part 22 that is away from the fixing part 1 are moved toward each other to achieve the effect of mounting the photovoltaic module 101 onto the module cable 102 through the connecting bracket 100.

[0056] When the wind is light, all photovoltaic modules 101 can be stably mounted on the module cable 102 via the connecting bracket 100, and the photovoltaic system 10 operates normally. When the wind is strong, the unremovable photovoltaic modules 1012 are subjected to wind force and the force is transmitted to the clamping part 2. Along the arrangement direction of the first clamping part 21 and the second clamping part 22, when the force on the first clamping part 21 and the second clamping part 22 reaches the second preset force value F, the first clamping part 21 and the second clamping part 22 move away from each other, so that the module cable 102 moves out of the clamping space 23. At this time, the unremovable photovoltaic modules 1012 and the connecting bracket 100 detach from the module cable 102 together to actively unload the photovoltaic bracket, thereby reducing the natural frequency, amplitude and force of the photovoltaic bracket from the wind load. The non-removable photovoltaic modules 1013 continue to function, realizing the function of the photovoltaic system 10 in converting solar energy into electrical energy.

[0057] According to one embodiment of this application, such as Figures 6-8As shown, the connecting bracket 100 may further include a fixing part 1, the fixing part 1 and the clamping part 2 are fixedly connected, the fixing part 1 and the clamping part 2 are arranged along a first direction, the first clamping part 21 is opposite to the free end of the fixing part 1 and the second clamping part 22 is opposite to the free end of the fixing part 1 and spaced apart to form an assembly port 24 communicating with the clamping space 23, the assembly port 24 is used to assemble the component cable 102.

[0058] The fixing part 1 and the clamping part 2 are fixedly connected. For example, the fixing part 1 and the clamping part 2 can be integrally formed, or they can be welded together. Figure 4 As shown, the photovoltaic module 101 may have a frame 1011. The fixing part 1 and the frame 1011 may be fixedly connected by means of, but not limited to, bolts, snap-fit, etc., so that the fixing part 1 and the photovoltaic module 101 can be assembled together, thereby enabling the connecting bracket 100 to be assembled with the photovoltaic module 101. The fixing part 1 and the clamping part 2 are arranged along a first direction. The free ends of the first clamping part 21 and the second clamping part 22 opposite to the free ends of the fixing part 1 are arranged opposite each other, and the free ends of the first clamping part 21 and the second clamping part 22 opposite to the free ends of the fixing part 1 are spaced apart to form an assembly port 24. The assembly port 24 is the open end of the above embodiment. The assembly port 24 communicates with the clamping space 23 so that the component cable 102 can be assembled into the clamping space 23 through the assembly port 24, thereby achieving the effect of smoothly assembling the connecting bracket 100 into the component cable 102. By setting the assembly port 24, the assembly difficulty of the connecting bracket 100 and the component cable 102 can be reduced, thereby improving the assembly efficiency of the connecting bracket 100.

[0059] According to one embodiment of this application, such as Figure 7 and Figure 8 As shown, a first guide flange 211 is formed at the free end of the first clamping part 21, and a second guide flange 221 is formed at the free end of the second clamping part 22. Along the arrangement direction of the first clamping part 21 and the second clamping part 22, the first guide flange 211 and the second guide flange 221 are opposite to each other and spaced apart, and the first guide flange 211 is bent toward the side away from the second clamping part 22, and the second guide flange 221 is bent toward the side away from the first clamping part 21.

[0060] The first clamping portion 21 has a first guide flange 211 formed at its free end. The second clamping portion 22 has a second guide flange 221 formed at its free end. Along the arrangement direction of the first clamping part 21 and the second clamping part 22, the first guide flange 211 and the second guide flange 221 are arranged opposite to each other and spaced apart. The first guide flange 211 is bent away from the second clamping part 22, and the second guide flange 221 is bent away from the first clamping part 21. This arrangement makes the arrangement of the first guide flange 211 and the second guide flange 221 reasonable. Along the first direction and from the end near the clamping space 23 to the end away from the clamping space 23, the distance between the first guide flange 211 and the second guide flange 221 gradually increases, which helps to reduce the difficulty of aligning the opening between the first guide flange 211 and the second guide flange 221 with the component cable 102, thereby further reducing the assembly difficulty of the connecting bracket 100.

[0061] During the assembly of the component cable 102 into the clamping space 23, the first guide flange 211 and the second guide flange 221 can also guide the component cable 102. Specifically, the component cable 102 is aligned with the opening between the first guide flange 211 and the second guide flange 221, and pressure is applied to the connecting bracket 100. Under the action of the force, the component cable 102 drives the first guide flange 211 and the second guide flange 221 to gradually move in a direction away from each other, and drives the free end of the first clamping part 21 away from the fixed part 1 and the free end of the second clamping part 22 away from the fixed part 1 to gradually move in a direction away from each other, so that the component cable 102 can be smoothly assembled into the clamping space 23.

[0062] After the component cable 102 is fully assembled into the clamping space 23, the component cable 102 no longer applies force to the first clamping part 21 and the second clamping part 22. The free ends of the first clamping part 21 and the second clamping part 22 that are away from the fixed part 1 return to their original state under the action of their own restoring force, so that the component cable 102 is stably clamped into the clamping space 23, and the connecting bracket 100 is smoothly assembled into the component cable 102.

[0063] According to one embodiment of this application, such as Figure 7 and Figure 8 As shown, the first clamping part 21 and the first guide flange 211 are integrally formed; and / or the second clamping part 22 and the second guide flange 221 are integrally formed.

[0064] In some embodiments of this application, the first clamping part 21 and the first guide flange 211 are integrally formed. In some embodiments of this application, the second clamping part 22 and the second guide flange 221 are integrally formed. In some embodiments of this application, the first clamping part 21 and the first guide flange 211 are integrally formed, and the second clamping part 22 and the second guide flange 221 are integrally formed. This application uses the example of the first clamping part 21 and the first guide flange 211 being integrally formed, and the second clamping part 22 and the second guide flange 221 being integrally formed. The first clamping part 21 and the first guide flange 211 are integrally formed, and the second clamping part 22 and the second guide flange 221 are integrally formed. That is to say, the first clamping part 21 and the first guide flange 211, the second clamping part 22 and the second guide flange 221 are constructed as integrally formed parts. The integrally formed parts have good structural strength. By making the first clamping part 21 and the first guide flange 211, the second clamping part 22 and the second guide flange 221 integrally formed, the connection reliability of the first clamping part 21 and the first guide flange 211, the second clamping part 22 and the second guide flange 221 can be improved, and the probability of breakage at the connection of the first clamping part 21 and the first guide flange 211, the second clamping part 22 and the second guide flange 221 can be reduced, thereby improving the structural strength and operational reliability of the connecting bracket 100.

[0065] According to one embodiment of this application, such as Figure 7 and Figure 8 As shown, the fixing part 1 includes: a first fixing part 11 and a second fixing part 12. The first fixing part 11 and the second fixing part 12 are opposite to each other and are both assembled with the corresponding photovoltaic module 101. The first fixing part 11 is fixedly connected to the first clamping part 21, and the second fixing part 12 is fixedly connected to the second clamping part 22.

[0066] Among them, such as Figure 8 As shown, the first fixing part 11 and the second fixing part 12 can be constructed as separate parts, such as... Figure 7 As shown, the first fixing part 11 and the second fixing part 12 can also be constructed as a single piece. For example, the first fixing part 11 and the second fixing part 12 can be fixedly connected by means of integral molding, welding, etc. The first fixing part 11 and the second fixing part 12 are arranged opposite to each other, and both the first fixing part 11 and the second fixing part 12 are used to assemble with the photovoltaic module 101. As some embodiments of this application, both the first fixing part 11 and the second fixing part 12 are formed with assembly holes 13. The assembly holes 13 of the first fixing part 11 and the assembly holes 13 of the second fixing part 12 are arranged opposite to each other. Bolts are sequentially passed through the two assembly holes 13 and connected to the photovoltaic module 101, and screwed and fixed with corresponding nuts, so that both the first fixing part 11 and the second fixing part 12 are assembled with the photovoltaic module 101.

[0067] In some embodiments of this application, the photovoltaic module 101, the first fixing part 11, and the second fixing part 12 are all formed with screw holes. Bolts are screwed into the three screw holes so that the first fixing part 11 and the second fixing part 12 are both assembled with the photovoltaic module 101. The first fixing part 11 and the first clamping part 21 are fixedly connected, for example, the first fixing part 11 and the first clamping part 21 can be fixedly connected by means of integral molding, welding, etc. The second fixing part 12 and the second clamping part 22 are fixedly connected, for example, the second fixing part 12 and the second clamping part 22 can be fixedly connected by means of integral molding, welding, etc. This arrangement helps to improve the connection reliability of the first fixing part 11 and the first clamping part 21, the second fixing part 12 and the second clamping part 22, and can reduce the probability of breakage at the connection of the first fixing part 11 and the first clamping part 21, the second fixing part 12 and the second clamping part 22, thereby further improving the structural strength and operational reliability of the connecting bracket 100.

[0068] According to one embodiment of this application, such as Figure 7 As shown, both the first clamping part 21 and the second clamping part 22 are constructed as arc-shaped structures and protrude in a direction away from each other.

[0069] The first clamping part 21 and the second clamping part 22 are both arc-shaped, and both protrude in a direction away from each other. By making both the first clamping part 21 and the second clamping part 22 arc-shaped and protruding in a direction away from each other, the structural design of the first clamping part 21 and the second clamping part 22 can be reasonable. This is beneficial because the shape of the clamping space 23 formed by the first clamping part 21 and the second clamping part 22 can be consistent with or approximately consistent with the shape of the component cable 102. The shape of the clamping space 23 is adapted to the shape of the component cable 102. When the component cable 102 is inserted into the clamping space 23, the photovoltaic module 101 can be stably assembled onto the component cable 102 through the connecting bracket 100. This helps to reduce the risk of damage or even breakage of the connecting bracket 100 or the component cable 102 caused by the shaking of the connecting bracket 100 and the photovoltaic module 101 on the component cable 102, thereby improving the working reliability and service life of the connecting bracket 100.

[0070] According to one embodiment of this application, such as Figure 7 and Figure 8 As shown, the first fixing part 11 includes a first mounting plate 111, and the second fixing part 12 includes a second mounting plate 121. The first mounting plate 111 and the second mounting plate 121 are opposite to each other and are both used to assemble with the photovoltaic module 101.

[0071] The first mounting plate 111 and the second mounting plate 121 are arranged opposite to each other, and both the first mounting plate 111 and the second mounting plate 121 are used to assemble with the photovoltaic module 101. As some embodiments of this application, both the first mounting plate 111 and the second mounting plate 121 are formed with assembly holes 13. The assembly holes 13 of the first mounting plate 111 and the second mounting plate 121 are arranged opposite to each other. Bolts are sequentially passed through the two assembly holes 13 and connected to the photovoltaic module 101, and screwed and fixed with the corresponding nuts, so that both the first mounting plate 111 and the second mounting plate 121 are assembled with the photovoltaic module 101. As some embodiments of this application, the photovoltaic module 101, the first mounting plate 111, and the second mounting plate 121 are all formed with screw holes. Bolts are screwed into the three screw holes in sequence so that the first fixing part 11 and the second fixing part 12 are both fitted and assembled with the photovoltaic module 101. Thus, the photovoltaic module 101 is fixedly assembled with the connecting bracket 100 through the first mounting plate 111 and the second mounting plate 121, thereby achieving the effect of assembling the photovoltaic module 101 onto the module cable 102 through the connecting bracket 100.

[0072] According to one embodiment of this application, such as Figure 7 and Figure 8 As shown, the first fixing part 11 further includes a first connecting plate 112, which is connected between the first mounting plate 111 and the first clamping part 21. The second fixing part 12 further includes a second connecting plate 122, which is connected between the second mounting plate 121 and the second clamping part 22. The first connecting plate 112 and the second connecting plate 122 are opposite to each other along the arrangement direction of the first clamping part 21 and the second clamping part 22, and the first connecting plate 112 and the second connecting plate 122 are fixedly fitted together.

[0073] The first connecting plate 112 is connected between the first mounting plate 111 and the first clamping part 21. For example, the first connecting plate 112, the first mounting plate 111, and the first clamping part 21 can be connected by, but is not limited to, integral molding or welding. The second connecting plate 122 is connected between the second mounting plate 121 and the second clamping part 22. For example, the second connecting plate 122, the second mounting plate 121, and the second clamping part 22 can be connected by, but is not limited to, integral molding or welding. Along the arrangement direction of the first clamping part 21 and the second clamping part 22, the first connecting plate 112 and the second connecting plate 122 are arranged opposite to each other, and the first connecting plate 112 and the second connecting plate 122 are fixedly fitted together.

[0074] In some embodiments of this application, both the first connecting plate 112 and the second connecting plate 122 have mounting through holes 14. The mounting through holes 14 of the first connecting plate 112 and the second connecting plate 122 are positioned opposite each other, allowing bolts to pass through the mounting through holes 14 sequentially and be fitted with corresponding nuts, thus fixing the first connecting plate 112 and the second connecting plate 122 in a secure fit. In some embodiments of this application, both the first connecting plate 112 and the second connecting plate 122 have threaded holes. Bolts are sequentially screwed into the two threaded holes, fixing the first connecting plate 112 and the second connecting plate 122 in a secure fit. By fixing the first connecting plate 112 and the second connecting plate 122 in a secure fit, the end of the first clamping part 21 near the first connecting plate 112 and the end of the second clamping part 22 near the second connecting plate 122 can be relatively stable, thereby allowing the first clamping part 21 and the second clamping part 22 to grip the module cable 102, achieving the effect of assembling the photovoltaic module 101 onto the module cable 102 via the connecting bracket 100.

[0075] According to one embodiment of this application, such as Figures 6-8 As shown, the first connecting plate 112 and the first mounting plate 111 are bent and connected, and the second connecting plate 122 and the second mounting plate 121 are bent and connected.

[0076] The bending connection between the first connecting plate 112 and the first mounting plate 111, and the bending connection between the second connecting plate 122 and the second mounting plate 121, makes the structural arrangement of the first connecting plate 112 and the first mounting plate 111, the second connecting plate 122 and the second mounting plate 121 reasonable. This is beneficial for the first mounting plate 111 and the second mounting plate 121 to be fixedly assembled with the photovoltaic module 101, while the first clamping part 21 and the second clamping part 22 can be smoothly assembled with the module cable 102. This reduces the risk of interference between the arc-shaped first clamping part 21 or the arc-shaped second clamping part 22 and the photovoltaic module 101 during the installation of the photovoltaic module 101 onto the module cable 102, thereby facilitating the smooth assembly of the photovoltaic module 101 onto the module cable 102 via the connecting bracket 100.

[0077] According to one embodiment of this application, such as Figure 6 As shown, the connecting bracket 100 may further include a connecting rope 3, which is fixedly connected to at least one of the fixing part 1 and the clamping part 2, and the connecting rope 3 is also used to fixally connect to the fixing structure.

[0078] The connecting rope 3 may be constructed as, but is not limited to, a cable, wire rope, etc. The connecting rope 3 is fixedly connected to at least one of the fixing part 1 and the clamping part 2. For example, the connecting rope 3 may be fixedly connected to the fixing part 1, or fixedly connected to the clamping part 2, or fixedly connected to both the fixing part 1 and the clamping part 2. The connecting rope 3 may be fixedly connected to at least one of the fixing part 1 and the clamping part 2 by means of binding, welding, etc. Furthermore, the connecting rope 3 is also used for fixed connection to a fixed structure, which may be constructed as the component cable 102 or other adjacent components (such as a stabilizing cable, anti-arch cable, truss, etc.).

[0079] Understandably, during the installation of photovoltaic module 101, a mounting plate is assembled onto a plurality of corresponding module cables 102 via at least two connecting brackets 100. For example, a mounting plate is fixedly assembled with two connecting brackets 100, and the two connecting brackets 100 are respectively snapped onto two different module cables 102, or a mounting plate is fixedly assembled with three connecting brackets 100, and the three connecting brackets 100 are respectively snapped onto three different module cables 102.

[0080] The different component cables 102 of the photovoltaic system 10 have a certain height difference, so that the photovoltaic module 101 can be at a certain angle, thereby better realizing the effect of converting solar energy into electrical energy. The connecting rope 3 is usually connected to the higher side of the component cable 102. When the connecting bracket 100 and the photovoltaic module 101 detach from the component cable 102, the connecting rope 3 can reduce the risk of the connecting bracket 100 and the photovoltaic module 101 flying around, thereby reducing the risk of them damaging other rigidly connected photovoltaic modules 101 or even pedestrians, which helps to improve the safety of the photovoltaic system 10.
