[0032] The embodiments of this application 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 application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-8 Description of a connection bracket 100 according to an embodiment of this application.

[0034] like Figures 1-6 As shown, this application provides a connection bracket 100 for a photovoltaic system 10. The photovoltaic system 10 includes a photovoltaic module 101 and a module cable 102. The connection bracket 100 includes a fixing part 1 and a clamping part 2. The fixing part 1 and the clamping part 2 are fixedly connected. The fixing part 1 is used to assemble with the photovoltaic module 101. The clamping part 2 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 clamping space 23 is used to pass through the module cable 102. 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 preset force value, so that the module cable 102 moves out of the clamping space 23.

[0035] 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 2 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 bolts, snap-fit, etc., so that the fixing part 1 and the photovoltaic module 101 can be assembled together. 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 clamping space 23 is used to pass through the module cable 102. The shape of the clamping space 23 is adapted to the shape of the module cable 102 so that when the module cable 102 is passed through the clamping space 23, the connecting bracket 100 and the photovoltaic module 101 can be stably assembled on the module cable 102.

[0036] When the force 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 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 on the first clamping part 21 and the second clamping part 22 reaches the 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. At this time, the light... The photovoltaic module 101 and the connecting bracket 100 detach together from the module cable 102, thereby actively unloading the photovoltaic bracket. This helps reduce the risk of wind continuously being transmitted to the photovoltaic bracket through the photovoltaic module 101 and the connecting bracket 100. In turn, it 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. This reduces the scale of economic losses and helps improve the stability and safety of the photovoltaic system 10. It also reduces the economic losses caused by winds exceeding the design value, acting as a "fuse".

[0037] Specifically, as some embodiments of this application, such as Figures 7-8 As shown, at least a portion of the photovoltaic modules 101 in the middle of the outer array of the photovoltaic support are connected to the module cables 102 via the connecting bracket 100 of this application. Further, 10%-50% of the photovoltaic modules 101 in one span of the outer array of the photovoltaic support are connected... Figure 7 , Figure 8 (The framed portion) is connected by the connecting bracket 100 of this application. For example, 10%, 20%, or 50% of the photovoltaic modules 101 in one span of the outer array of the photovoltaic bracket are connected by the connecting bracket 100 of this application, and the remaining photovoltaic modules 101 are rigidly connected to the module cable 102.

[0038] As some embodiments of this application, such as Figures 7-8 As shown, connecting brackets 100 of different specifications are set up to assemble photovoltaic modules 101 and module cables 102 through connecting brackets 100 of different specifications. For example, 10%-50% of the photovoltaic modules 101 in one span of the outer array of the photovoltaic bracket ( Figure 7 , Figure 8 The selected portion is connected by removing the connecting bracket 100 with a preset force value of F, and the remaining photovoltaic modules 101 are connected by removing the connecting bracket 100 with a preset force value greater than F. It can be understood that the preset force value of the connecting bracket 100 can be achieved by changing the width and thickness of the connecting bracket 100.

[0039] The fixing part 1 is fixed to the photovoltaic module 101 by bolts. It can be understood that the fixing part 1 and the photovoltaic module 101 are assembled before the connecting bracket 100 and the module cable 102 are assembled. This can avoid the installer having to look up to operate, which helps to reduce the labor intensity and improve the installation efficiency of the connecting bracket 100.

[0040] The first clamping part 21 and the second clamping part 22, which are opposite to the fixed part 1, are moved toward each other in a direction away from each other, so that the clamping space 23 is opened. The module cable 102 is moved into the clamping space 23 through the open end, and the first clamping part 21 and the second clamping part 22, which are opposite to the fixed part 1, are moved toward each other in a direction close to each other, so as to achieve the effect of installing the photovoltaic module 101 on the module cable 102 through the connecting bracket 100.

[0041] 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 photovoltaic modules 101 are subjected to wind force and transmit the force to the clamping part 2, along the arrangement direction of the first clamping part 21 and the second clamping part 22, i.e. Figure 4 In the X direction, when the force on the first clamping part 21 and the second clamping part 22 reaches a 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, at least some of the photovoltaic modules 101 and the connecting bracket 100 in the middle of the outer array of the photovoltaic support detach from the module cable 102 together, so as to actively unload the photovoltaic support, thereby reducing the natural frequency, amplitude and force of the photovoltaic support from wind load. The remaining photovoltaic modules 101 that are rigidly connected to the module cable 102 or connected to the module cable 102 by removing the connecting bracket 100 with a preset force value greater than F continue to work, realizing the function of the photovoltaic system 10 to convert solar energy into electrical energy.

[0042] Therefore, by arranging the first clamping part 21 and the second clamping part 22 opposite to each other to form a clamping space 23 for threading the component cable 102, and by moving the first clamping part 21 and the second clamping part 22 away from each other when subjected to a preset force value so that the component cable 102 moves out of the clamping space 23, the photovoltaic module 101 and the connecting bracket 100 can be detached from the component cable 102, thereby actively unloading the photovoltaic bracket, reducing the risk of major losses such as microcracks in most of the photovoltaic modules 101, tearing and falling off of the frame 1011, or even the collapse of the entire row of photovoltaic brackets. 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".

[0043] According to one embodiment of this application, such as Figure 4 and Figure 5As shown, the fixing part 1 and the clamping part 2 are arranged along the first direction. The free end of the first clamping part 21 away from the fixing part 1 and the second clamping part 22 away from the free end of the fixing part 1 are opposite to each other 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. The first direction intersects with the arrangement direction of the first clamping part 21 and the second clamping part 22.

[0044] The fixing part 1 and the clamping part 2 are arranged along a first direction, which is... Figure 4 In the Y direction, the free ends of the first clamping part 21 and the second clamping part 22 opposite to the free ends of the fixed part 1 are arranged opposite to each other, and the free ends of the first clamping part 21 and the second clamping part 22 are spaced apart to form an assembly port 24. The assembly port 24 is the open end in 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. The first direction intersects with the arrangement direction of the first clamping part 21 and the second clamping part 22, that is, the X direction intersects with the Y direction. Furthermore, the first direction can be perpendicular to the arrangement direction of the first clamping part 21 and the second clamping part 22, that is, the X direction is perpendicular to the Y direction.

[0045] According to one embodiment of this application, such as Figure 5 and Figure 6 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] According to one embodiment of this application, such as Figure 6 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.

[0050] 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.

[0051] According to one embodiment of this application, such as Figure 5 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.

[0052] 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.

[0053] According to one embodiment of this application, such as Figure 5 and Figure 6As shown, the fixing part 1 may include: 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 used to assemble with the photovoltaic module 101. The first fixing part 11 and the first clamping part 21 are fixedly connected, and the second fixing part 12 and the second clamping part 22 are fixedly connected.

[0054] Among them, such as Figure 6 As shown, the first fixing part 11 and the second fixing part 12 can be constructed as separate parts, such as... Figure 5 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.

[0055] 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.

[0056] According to one embodiment of this application, such as Figure 4 and Figure 5 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.

[0057] 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.

[0058] According to one embodiment of this application, such as Figure 4 and Figure 5 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.

[0059] 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.

[0060] 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.

[0061] According to one embodiment of this application, such as Figures 4-6 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.

[0062] 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.

[0063] According to one embodiment of this application, such as Figure 4 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.

[0064] 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.).

[0065] 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.

[0066] 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.

[0067] The photovoltaic system 10 according to an embodiment of this application includes the connecting bracket 100 described in the above embodiment. The photovoltaic system 10 includes a photovoltaic module 101 and a module cable 102. 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-fits, etc., so that the fixing part 1 and the photovoltaic module 101 can be assembled together. When the module cable 102 passes through the clamping space 23, the connecting bracket 100 and the photovoltaic module 101 can be stably assembled on the module cable 102.

[0068] 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 photovoltaic modules 101 are subjected to wind force and transmit the force to the clamping part 2, along the arrangement direction of the first clamping part 21 and the second clamping part 22, i.e. Figure 4In the X direction, when the force on the first clamping part 21 and the second clamping part 22 reaches a 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, at least some of the photovoltaic modules 101 and the connecting bracket 100 in the middle of the outer array of the photovoltaic support detach from the module cable 102 together, so as to actively unload the photovoltaic support, thereby reducing the natural frequency, amplitude and force of the photovoltaic support from wind load. The remaining photovoltaic modules 101 that are rigidly connected to the module cable 102 or connected to the module cable 102 by removing the connecting bracket 100 with a preset force value greater than F continue to work, realizing the function of the photovoltaic system 10 to convert solar energy into electrical energy.

[0069] Therefore, by arranging the first clamping part 21 and the second clamping part 22 opposite to each other to form a clamping space 23 for threading the component cable 102, and by moving the first clamping part 21 and the second clamping part 22 away from each other when subjected to a preset force value so that the component cable 102 moves out of the clamping space 23, the photovoltaic module 101 and the connecting bracket 100 can be detached from the component cable 102, thereby actively unloading the photovoltaic bracket, reducing the risk of major losses such as microcracks in most of the photovoltaic modules 101, tearing and falling off of the frame 1011, or even the collapse of the entire row of photovoltaic brackets. 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".
