[0036] In the related art, photovoltaic power stations mostly determine the most unfavorable load that photovoltaic brackets bear during operation based on a relatively high reliability index, and then use the most unfavorable load as a design requirement to select the assembly components connecting the photovoltaic brackets and photovoltaic modules, thereby increasing the load borne by the photovoltaic brackets and assembly components and ensuring the stable bearing effect of the photovoltaic brackets on the photovoltaic modules. However, in the actual operation of photovoltaic power stations, the probability of photovoltaic brackets encountering the most unfavorable load is extremely small, and the structural design of assembly components that meet the requirements of bearing the most unfavorable load is relatively cumbersome and costly, which leads to redundant designs of assembly components and photovoltaic brackets, making the overall construction cost of photovoltaic brackets relatively large, reducing the practicality of photovoltaic brackets. In view of the above problems, the utility model proposes a photovoltaic bracket 1000.
[0037] Reference Figures 1 to 8 In the embodiment of the utility model, the photovoltaic bracket 1000 includes a supporting frame 300, a load-bearing cable 500 and an assembly component 100. The load-bearing cable 500 is connected to the supporting frame 300, and the load-bearing cable 500 is used to bear and support the photovoltaic component 2000. The load-bearing cable 500 includes a first load-bearing section 51 and a second load-bearing section 53 located at both ends of the first load-bearing section 51; the assembly component 100 includes a first component 10 and a second component 30, the first component 10 is connected to the first load-bearing section 51, the second component 30 is connected to the second load-bearing section 53, the first component 10 and the second component 30 are used to connect and fix the photovoltaic component 2000, and the ultimate load bearing capacity of the first component 10 is less than the ultimate load bearing capacity of the second component 30.
[0038] It can be understood that the photovoltaic bracket 1000 can be fixedly installed on the installation plane of the photovoltaic power station using a support frame 300 such as columns or triangular pillars. At this time, multiple columns or triangular pillars of the support frame 300 can be arranged side by side at a certain interval, so that the load-bearing cable 500 can be laid on the top surface 23 of the support frame 300, and connected to the support frame 300 to maintain a certain tension, so that the load-bearing cable 500 can have a certain load-bearing capacity, and then by connecting the assembly component 100 to the load-bearing cable 500, and using the assembly component 100 to tightly connect with the frame 200 of the photovoltaic component 2000, the photovoltaic bracket 1000 is able to carry and install the photovoltaic component 2000, thereby ensuring the stable operation of the photovoltaic power station.
[0039] The assembly component 100 can be fixedly connected to the load-bearing cable 500 by a clamp or a clip, and the assembly component 100 of the corresponding model can be selected according to the installation requirements of the photovoltaic assembly 2000 to fix and install the photovoltaic assembly 2000. In the present application, the line segment of the load-bearing cable 500 located on the support frame 300 for carrying the photovoltaic assembly 2000 is divided into a first load-bearing segment 51 and a second load-bearing segment 53. The first load-bearing segment 51 can be a partial line segment of the load-bearing cable 500 located in the central area of the photovoltaic support 1000, so that the other parts of the load-bearing cable 500 located at both ends of the first load-bearing segment 51 are set as the second load-bearing segment 53. Furthermore, by making the assembly component 100 include the first component 10 and the second component 30 with different load bearing capacities, the ultimate load bearing capacity of the first component 10 is set to be smaller than the ultimate load bearing capacity of the second component 30, the first component 10 with a smaller load bearing capacity can be arranged in the first bearing section 51, and the second component 30 with a larger load bearing capacity can be arranged in the second bearing section 53, and the first component 10 and the second component 30 can be used to fix the photovoltaic assembly 2000 to achieve the assembly of the photovoltaic assembly 2000. Among them, the second component 30 can be designed to meet the requirements of the photovoltaic support 1000 to bear the most extreme load, and the first component 10 can be designed to meet the requirements of the photovoltaic support 1000 to bear a larger load, for example, the second component 30 meets the most unfavorable load requirements of the photovoltaic support 1000 when the photovoltaic power station operates for 25 years, and the first component 10 meets the most unfavorable load requirements of the photovoltaic support 1000 when the photovoltaic power station operates for 10 years. In this way, by using the first component 10 with lower design requirements for some of the assembly components 100 of the photovoltaic bracket 1000, the overall production cost of the assembly components 100 can be effectively reduced, which is conducive to better optimizing the redundant design of the photovoltaic bracket 1000. By arranging the first component 10 at the first bearing section 51 in the central area of the bearing cable 500, when the photovoltaic power station encounters severe adverse weather conditions and the photovoltaic bracket 1000 is subjected to a large load, the first component 10 can be broken due to the large load, so that the photovoltaic component 2000 located on the first bearing section 51 falls off the photovoltaic bracket 1000, and then as the photovoltaic component 2000 located in the central area of the photovoltaic bracket 1000 is detached, the contact area of the photovoltaic component 2000 as a whole that bears the load can be reduced, so that the load borne by the photovoltaic bracket 1000 as a whole can be greatly reduced as the photovoltaic component 2000 on the first bearing section 51 is detached, so that the second component 30 can more stably fix the photovoltaic component 2000 located on the second bearing section 53, thereby avoiding a certain probability of the entire photovoltaic bracket 1000 tipping over when it is subjected to a load greater than the maximum load that the second component 30 can withstand, thereby further improving the overall structural reliability and practicality of the photovoltaic bracket 1000.
[0040] Among them, the first component 10 and the second component 30 can be different in material, so that the first component 10 is made of a material with lower structural strength, and the second component 30 is made of a material with better structural strength, so that the load-bearing capacity of the first component 10 is lower than the load-bearing capacity of the second component 30; or the first component 10 and the second component 30 can be different in structural shape, so that the connection points between the first component 10 and the photovoltaic component 2000 are fewer than the connection points between the second component 30 and the photovoltaic component 2000, so that the second component 30 can have a larger contact area, so that the load-bearing capacity of the first component 10 is lower than the load-bearing capacity of the second component 30; or, the first component 10 and the second component 30 can have certain differences in material and structural shape, and the differentiated settings of the first component 10 and the second component 30 are realized, so that the load-bearing capacity of the first component 10 is lower than the load-bearing capacity of the second component 30.
[0041] The technical solution of the utility model divides the load-bearing cable 500 into a first load-bearing section 51 located in the central area of the photovoltaic bracket 1000 and a second load-bearing section 53 located at both ends of the first load-bearing section 51, and uses the first component 10 and the second component 30 to fix the photovoltaic assembly 2000 on the photovoltaic bracket 1000, and makes the ultimate load that the first component 10 can bear smaller than the ultimate load that the second component 30 can bear. The first component 10 can be used to reduce the local design requirements of the photovoltaic bracket 1000, which is conducive to better reducing the overall production cost of the photovoltaic bracket 1000 and optimizing the redundant design of the photovoltaic bracket 1000. When the photovoltaic bracket 1000 is subjected to a larger ultimate load, the first component 10 can be broken under the action of the larger load, so that the photovoltaic component 2000 on the first bearing section 51 loses the fixation of the first component 10 and detaches from the photovoltaic bracket 1000, thereby reducing the load force borne by the photovoltaic bracket 1000 as a whole, effectively preventing the photovoltaic bracket 1000 from tipping over as a whole due to a strong load, and ensuring the connection and fixation of the second component 30 to the photovoltaic component 2000 located on the second bearing section 53, further improving the practicality and reliability of the photovoltaic bracket 1000.
[0042] Reference Figure 3 , Figure 4 and Figure 6 In one embodiment of the utility model, the first component 10 includes a first support plate 11 and a first fastener 13. The first support plate 11 is connected to the load-bearing cable 500 and is used to support the bottom edge 21 of the frame 200 of the photovoltaic component 2000; the first fastener 13 is connected to the first support plate 11 and is used to fix the frame 200 of the photovoltaic component 2000.
[0043] In this embodiment, the first component 10 can place a first support plate 11 with a certain bearing area on the first bearing section 51, and then connect the first bearing section 51 and the first support plate 11 by using a clamp or a clamp structure to achieve the connection and fixation of the first component 10 and the bearing cable 500. At this time, by arranging the first fastener 13 on the first support plate 11, the photovoltaic assembly 2000 can be stably supported and fixed on the first support plate 11 by using the first fastener 13, so as to achieve the fixed connection between the photovoltaic assembly 2000 and the first component 10, and then ensure the installation and fixation of the photovoltaic assembly 2000 on the photovoltaic bracket 1000 by the first component 10. Among them, the first fastener 13 can be a clamping and fixing mechanism with the outer periphery of the frame of the photovoltaic assembly 2000; or it can be a fastening structure such as a self-tapping screw, a bolt or a pin, etc. The first fastener 13 can be used to connect and fix the first bearing section 51 and the photovoltaic assembly 2000 with the first support plate 11, so as to achieve a simpler assembly effect of the first component 10 and improve the assembly efficiency of the first component 10.
[0044] Among them, if the second component 30 adopts a structural setting consistent with the first component 10, the structural strength or size specification of the first fastener 13 of the first component 10 can be made smaller than the structural strength or size specification of the second fastener 33 of the second component 30, or the second component 30 can adopt a more complex connection structure than the first component 10, thereby ensuring the difference in the ultimate load bearing capacity between the first component 10 and the second component 30, and further improving the overall structural reliability of the photovoltaic bracket 1000.
[0045] In an embodiment of the present invention, the first fastener 13 includes a clip structure, and the clip structure is used to clamp and fix the outer periphery of the frame of the photovoltaic component 2000.
[0046] In this embodiment, the first fastener 13 can be set in the form of a clip structure, so that the first component 10 can use the first fastener 13 to abut and clamp the top surface, bottom edge and side wall of the frame of the photovoltaic component 2000, thereby achieving stable and reliable fixation of the photovoltaic component 2000 by the first component 10, and further improving the connection stability and reliability between the first component 10 and the photovoltaic component 2000.
[0047] Among them, when the second component 30 is also arranged in the photovoltaic bracket 1000 in the form of clamping and fixing the photovoltaic component 2000, the overall structural strength or model size of the clamp structure can be made smaller than the structural strength and model size of the second component 30, thereby ensuring the difference in the ultimate load bearing capacity between the first component 10 and the second component 30, so that when the photovoltaic bracket 1000 is subjected to a larger ultimate load, the load on the first component may be too large and break, so that the load borne by the photovoltaic bracket 1000 as a whole can be greatly reduced as the photovoltaic component 2000 on the first load-bearing section 51 is detached, thereby ensuring the overall structural stability of the photovoltaic bracket 1000.
[0048] Reference Figures 4 to 7 In one embodiment of the utility model, the first support plate 11 is provided with an assembly hole 111, and the first fastener 13 includes a fastening plug 131 and a fastening plug 133. The fastening plug 131 is passed through the assembly hole 111, and a bolt cap 1311 is provided at one end of the fastening plug 131. The bolt cap 1311 is used to abut against the bottom edge 21 of the frame 200 of the photovoltaic component 2000; the fastening plug 133 abuts against the side of the first support plate 11 facing the load-bearing cable 500, and the fastening plug 133 is provided with a mounting hole 1331. The fastening plug 131 is inserted into the mounting hole 1331 and connected to the fastening plug 133.
[0049] In this embodiment, the first fastener 13 can realize the fastening connection between the photovoltaic module 2000 and the first support plate 11 by means of the matching connection of the fastening plug 131 and the fastening plug 133. During the assembly process, the fastening plug 131 can be firstly aligned with the hole of the bottom edge 21 of the frame 200 of the photovoltaic module 2000 and the assembly hole 111 of the first support plate 11, so that the fastening plug 131 is inserted into the assembly hole 111, and the bolt cap 133 at one end of the fastening plug 131 is fixed. 11 abuts against the bottom edge 21 of the frame 200 of the photovoltaic component 2000. At this time, by aligning the fastening plug 131 with the mounting hole 1331 of the fastening plug 133 on the side of the first support plate 11 facing away from the photovoltaic component 2000, the fastening plug 131 can be inserted into the mounting hole 1331, and the fastening plug 133 is connected and fixed to the fastening plug 131, so that the fastening plug 133 abuts against the surface of the first support plate 11 facing away from the photovoltaic component 2000. Furthermore, the fastening bolt 131 and the fastening plug 133 are used to penetrate the bottom edge 21 of the frame 200 of the photovoltaic component 2000 and connect and fix it with the first support plate 11. The bolt cap 1311 of the fastening bolt 131 can abut against the side of the bottom edge 21 of the frame 200 of the photovoltaic component 2000 that is away from the first support plate 11, and the fastening plug 133 can abut against the board surface of the first support plate 11 that is away from the photovoltaic component 2000, so that the bolt cap 1311 and the fastening plug 133 can clamp and fix the bottom edge 21 of the frame 200 of the photovoltaic component 2000 and the first support plate 11, thereby realizing a stable connection and fixation between the first component 10 and the photovoltaic component 2000. The fastening plug 131 can be threadedly connected with the mounting hole 1331 of the fastening plug 133, or the fastening plug 131 and the fastening plug 133 can be stably connected by using a buckle or a sealant after the fastening plug 131 is inserted into the mounting hole 1331, thereby ensuring the connection stability and reliability of the fastening plug 131 and the fastening plug 133. By using the fastening plug 131 and the fastening plug 133 to cooperate and connect to realize the connection and assembly of the first component 10 and the photovoltaic assembly 2000, it can be beneficial to better improve the assembly convenience of the first component 10 and improve the overall assembly efficiency of the photovoltaic bracket 1000.
[0050] Reference Figure 4 and Figure 5 In one embodiment of the utility model, the fastening plug 131 includes a weakened section 1312 and a connecting section 1313, one end of the weakened section 1312 is connected to the bolt cap 1311; the connecting section 1313 is connected to the other end of the weakened section 1312, the connecting section 1313 is inserted into the mounting hole 1331, and is threadedly connected to the inner wall of the mounting hole 1331, and the outer diameter of the connecting section 1313 is larger than the outer diameter of the weakened section 1312.
[0051] In this embodiment, the fastening plug 131 can be provided with an external thread on the connecting section 1313 and an internal thread on the inner wall of the mounting hole 1331, so that the fastening plug 131 can be connected with the fastening plug 133 through a threaded fit when the connecting section 1313 is used to pass through the assembly hole 111 and is exposed on the side of the first support plate 11 facing away from the photovoltaic component 2000, so that the fastening plug 133 can be directly screwed into the fastening plug 131 and cooperate with the fastening plug 131 to fix the photovoltaic component 2000 and the first support plate 11, thereby further improving the assembly convenience of the first component 10. At the same time, the outer diameter of the connecting section 1313 of the fastening plug 131 is set larger than the outer diameter of the weakened section 1312, so that the structural strength of the weakened section 1312 can be set smaller than the structural strength of the connecting section 1313, so that the weakened section 1312 can form a local structural weak point of the fastening plug 131, and then when the photovoltaic bracket 1000 is subjected to a large load, the first component 10 can be broken at the weakened section 1312 of the fastening plug 131, thereby realizing the relative separation of the photovoltaic component 2000 and the first support plate 11, so that the overall load borne by the photovoltaic bracket 1000 can be reduced. By utilizing the weakened section 1312 of the fastening bolt to break and separate the first component 10 from the photovoltaic assembly 2000, damage to the frame 200 and the first support plate 11 of the photovoltaic assembly 2000 can be reduced, so that the photovoltaic power station can replace the fastening plug 131 to connect the photovoltaic assembly 2000 and the first support plate 11 after the load is eliminated, which is conducive to better reducing the consumables of the photovoltaic bracket 1000 and further improving the practicality of the photovoltaic bracket 1000.
[0052] Reference Figure 6 and Figure 7 In one embodiment of the utility model, a receiving groove 1314 is provided on the outer peripheral side of the fastening plug 131, and the fastening plug 131 is provided with an elastic member 1315 and a tightening block 1316. The tightening block 1316 is movably inserted into the receiving groove 1314, and the notch exposed in the receiving groove 1314 abuts against the inner wall of the hole of the mounting hole 1331. The elastic member 1315 connects the tightening block 1316 and the bottom wall of the receiving groove 1314.
[0053] In this embodiment, the fastening plug 131 can be fastened by setting a receiving groove 1314 on the periphery, and connecting the bottom wall of the receiving groove 1314 and the tightening block 1316 using an elastic member 1315, so that the tightening block 1316 can compress the elastic member 1315 to achieve movement in the receiving groove 1314. By making the accommodating groove 1314 and the tightening block 1316 exposed on the side of the first support plate 11 facing away from the photovoltaic component 2000 after the fastening plug 131 passes through the assembly hole 111, the inner diameter of the mounting hole 1331 of the fastening plug 133 can be set slightly larger than the outer diameter of the fastening plug 131. Furthermore, during the assembly process, by making the tightening block 1316 compress the elastic member 1315 to retract into the accommodating groove 1314, and then inserting the fastening plug 131 into the mounting hole 1331, the tightening block 1316 can be pressed against the inner wall of the mounting hole 1331 under the action of the elastic member 1315 restoring the elastic deformation, thereby realizing the connection and fixation between the fastening plug 131 and the fastening plug 133, and ensuring the fixed connection between the first component 10 and the bottom edge 21 of the frame 200 of the photovoltaic component 2000. The installation method of arranging the elastic member 1315 and the tightening block 1316 on the outer periphery of the fastening plug 131 to abut against the inner wall of the mounting hole 1331 to fix the fastening plug 131 is conducive to further improving the assembly convenience of the first component 10 and improving the assembly efficiency of the photovoltaic bracket 1000. When the photovoltaic bracket 1000 is subjected to a large load, if the load is greater than the friction between the tightening block 1316 and the fastening plug 131 and the inner wall of the mounting hole 1331, the load force can separate the fastening plug 131 from the fastening plug 133, thereby separating the photovoltaic assembly 2000 from the first support plate 11, reducing the overall load borne by the photovoltaic bracket 1000, and preventing the photovoltaic bracket 1000 from tipping over as a whole. The tightening block 1316 is used to press against the inner wall of the mounting hole 1331 to achieve fixation, so that the fastening plug 131 can be reconnected and fixed to the fastening plug 133 after being pulled out of the fastening plug 133 under the action of external force, so that the photovoltaic bracket 1000 can be reassembled with the first component 10 to connect and fix the photovoltaic component 2000 after the load is eliminated, which is conducive to better reducing the consumables of the photovoltaic bracket 1000 and further improving the practicality of the photovoltaic bracket 1000.
[0054] Reference Figure 7 In one embodiment of the utility model, a card slot 1333 is provided on the inner wall of the mounting hole 1331 , and the card slot 1333 is provided corresponding to the receiving groove 1314 , and one end of the tightening block 1316 exposed from the notch of the receiving groove 1314 is card-connected to the card slot 1333 .
[0055] In this embodiment, the fastening plug 133 can be recessed with a slot 1333 on the inner wall of the mounting hole 1331, and the position of the slot 1333 can correspond to the accommodating groove 1314 of the fastening plug 131, so that after the fastening plug 131 and the fastening plug 133 cooperate to clamp and fix the photovoltaic component 2000 and the first support plate 11, the top tightening block 1316 can be clamped in the slot 1333 under the action of the elastic member 1315 restoring the elastic deformation, so that the fastening plug 131 and the fastening plug 133 can utilize the clamping fixation of the top tightening block 1316 and the slot 1333 to further improve the load-bearing capacity of the first component 10, so that the first component 10 can only be separated from the fastening plug 131 and the fastening plug 133 when it is subjected to a maximum load close to the second component 30, thereby further improving the structural stability and reliability of the photovoltaic bracket 1000.
[0056] In one embodiment of the present invention, an anti-slip structure is provided on the outer circumference of the fastening plug 131 , and / or an anti-slip structure is provided on the end surface of the tightening block 1316 facing away from the bottom wall of the accommodating groove 1314 .
[0057] In this embodiment, an anti-slip structure such as an anti-slip strip or anti-slip protrusion is provided on the outer peripheral side of the fastening plug 131, and the anti-slip structure can be used to increase the friction between the fastening plug 131 and the inner wall of the mounting hole 1331, so that the fastening plug 131 can be better pressed and fixed on the inner wall of the mounting hole 1331 under the action of the elastic member 1315 to restore the elastic deformation, which is beneficial to further improve the load-bearing capacity of the first component 10, so that the fastening plug 131 and the fastening plug 133 can be separated only when the first component 10 is subjected to a load close to the maximum bearing load of the second component 30, thereby further improving the overall structural stability and reliability of the photovoltaic bracket 1000.
[0058] In addition, by providing an anti-slip structure such as an anti-slip strip or anti-slip protrusion at the end surface of the tightening block 1316 facing away from the bottom wall of the accommodating groove 1314, the friction between the tightening block 1316 and the inner wall of the mounting hole 1331 can be further increased under the action of the anti-slip structure, so that the tightening block 1316 can more stably press against the inner wall of the mounting hole 1331, which is beneficial to further improve the load-bearing capacity of the first component 10, so that the first component 10 can only be detached from the fastening bolt 131 and the fastening plug 133 when it is subjected to a maximum load close to that of the second component 30, thereby further improving the overall structural stability and reliability of the photovoltaic bracket 1000.
[0059] In an embodiment of the present invention, the fastening plug 131 is made of plastic or plastic-steel.
[0060] In this embodiment, the fastening plug 131 can be a bolt or a pin structure made of a material with low structural strength such as plastic or plastic steel, so that when the photovoltaic bracket 1000 is subjected to a large load, the fastening plug 131 can be broken to achieve the separation of the photovoltaic bracket 1000 and the first support plate 11, which is beneficial to avoid the photovoltaic component 2000 or the first support plate 11 from breaking, and then the photovoltaic bracket 1000 can be reassembled to connect the first component 10 and the photovoltaic component 2000 by replacing the fastening plug 131 after the load is eliminated, thereby better reducing the consumables of the photovoltaic bracket 1000 and further improving the practicality of the photovoltaic bracket 1000.
[0061] Reference Figure 8 In one embodiment of the utility model, the second component 30 includes a second support plate 31 and a second fastener 33. The second support plate 31 is connected to the load-bearing cable 500 and is used to support the bottom edge 21 of the frame 200 of the photovoltaic component 2000; the second fastener 33 is connected to the second support plate 31 and is used to connect the bottom edge 21 of the frame 200 of the photovoltaic component 2000.
[0062] In this embodiment, the second member 30 can place the second support plate 31 on the second bearing section 53 of the bearing cable 500, and use a structure such as a clamp or a clip to connect and fix the bearing cable 500 and the second support plate 31, and then use the second support plate 31 to better increase the contact area between the second member 30 and the bottom edge 21 of the frame 200 of the photovoltaic assembly 2000. At this time, by arranging the second fastener 33 on the second support plate 31, the second fastener 33 can be used to stably support and fix the photovoltaic assembly 2000 on the second support plate 31, so as to achieve a fixed connection between the photovoltaic assembly 2000 and the second member 30, and then ensure that the second member 30 is installed and fixed on the photovoltaic bracket 1000. Among them, the second fastener 33 can be a clamping mechanism that is clamped and fixed with the outer periphery of the frame of the photovoltaic component 2000; or it can be a fastening structure such as self-tapping screws, bolts or pins, etc. The second fastener 33 can be used to connect and fix the second bearing section 53 and the photovoltaic component 2000 with the second support plate 31, which can achieve a simpler assembly effect of the second component 30 and improve the assembly efficiency of the second component 30.
[0063] Among them, if the second component 30 adopts a structural setting consistent with the first component 10, the structural strength or size specification of the second fastener 33 of the second component 30 can be made greater than the structural strength or size specification of the first fastener 13 of the first component 10, or the second component 30 can adopt a more complex connection structure than the first component 10, to ensure the difference in the ultimate load bearing capacity between the first component 10 and the second component 30, so that the second component 30 can remain installed and fixed on the second bearing section 53 after the first component 10 is damaged by excessive load, thereby further improving the overall structural reliability of the photovoltaic bracket 1000.
[0064] Reference Figure 8 In one embodiment of the utility model, the second fastener 33 includes a connecting structure 331 and a pressing block structure 333. The connecting structure 331 is used to connect and fix the second support plate 31 and the bottom edge of the frame of the photovoltaic component 2000; the pressing block structure 333 is connected to the second support plate 31 and is used to press and fix the top surface 23 of the frame 200 of the photovoltaic component 2000.
[0065] In this embodiment, a connecting structure such as a buckle, bolt or pin is provided on the second support plate 31 to connect and fix the bottom edge 21 of the frame 200 of the photovoltaic component 2000, and a pressure block structure 333 is used to press the top surface 23 of the frame 200 of the photovoltaic component 2000 to connect and fix it on the second support plate 31. Under the action of the pressure block structure 333 and the second fastener 33, the second component 30 can be more stably and reliably connected to and fixed to the photovoltaic component 2000, so that the photovoltaic bracket 1000 and the photovoltaic component 2000 located at the second bearing section 53 can withstand a larger load, thereby further improving the structural stability and reliability of the photovoltaic bracket 1000.
[0066] In an embodiment of the present invention, the photovoltaic support 1000 is further provided with a buffer structure, which is disposed below the load-bearing cable 500 and corresponding to the first load-bearing section 51 .
[0067] In this embodiment, a buffer structure such as sandbags or soft cushions can be placed at the bottom of the photovoltaic bracket 1000 at a position corresponding to the first bearing section 51, so that when the photovoltaic bracket 1000 is subjected to a large load and the first component 10 is separated from the photovoltaic component 2000, the photovoltaic component 2000 can be separated from the photovoltaic bracket 1000 and fall on the buffer structure. The buffer structure is used to buffer the force exerted on the photovoltaic component 2000 when it falls, which can better protect the photovoltaic component 2000. The photovoltaic power station can reassemble and fix the photovoltaic component 2000 after the load is eliminated, thereby reducing the maintenance and replacement of the photovoltaic component 2000 and further improving the practicality and reliability of the photovoltaic bracket 1000.
