[0002] Flexible photovoltaic support is a large-span photovoltaic module support structure mainly composed of prestressed steel cables (steel strands), tensile members on both sides, and supporting columns in the middle. Compared with traditional fixed photovoltaic supports, it is flexible to install, has high site space utilization, and uses less steel.

[0003] There are two main ways to connect components of traditional fixed photovoltaic brackets: block connection and pallet connection. Both connection methods use bolts to fix the block or pallet to the purlin of the photovoltaic bracket to fix the photovoltaic components. The structural feature of the fixed photovoltaic bracket is a rigid structure.

[0004] Different from traditional fixed photovoltaic brackets, flexible photovoltaic brackets will produce displacement and deflection changes in the cable structure during normal operation due to their own structural characteristics. In the flexible photovoltaic bracket system, if the traditional fixed photovoltaic bracket assembly installation method is adopted, a series of problems will occur, such as loosening of the pressure block bolts, hidden cracks in the photovoltaic components, and the photovoltaic components falling off during the deformation of the steel strands, causing economic losses and bringing safety hazards. Therefore, it is necessary to provide a photovoltaic TV component connection method that can not only cope with the displacement changes of the cable structure under normal working conditions, allowing it to deform freely between two photovoltaic components, but also stably and firmly connect the cable structure to the photovoltaic component to solve the above problems.

[0027] See also Figure 1-6The utility model provides a technical solution: a flexible photovoltaic bracket connection structure, which includes: a U-shaped bolt 1, which is used to connect the steel strand 2 with the inverted "J"-shaped support plate 3 and the deformable pressing block 4. The middle part of the U-shaped bolt 1 is penetrated by the inverted "J"-shaped support plate 3. The U-shaped bolt 1 is clamped on the steel strand 2, and then the inverted "J"-shaped support plate 3 is fixed to the U-shaped bolt 1 with a first set of fastening nuts 5. Both sides above the inverted "J"-shaped support plate 3 are equipped with photovoltaic modules 6. The upper end of the photovoltaic module 6 is in contact with the deformable pressing block 4. The deformable pressing block 4 is put on the U-shaped bolt 1, and the top is pressed to the upper edge of the frame of the photovoltaic module 6. The second set of fastening nuts 5 is used to tighten the U-shaped bolt 1. Tightly fix so that the deformable pressing block 4 presses the photovoltaic component 6. The deformable pressing block 4 is in an inverted "J" shape. The upper part of the U-shaped bolt 1 passes through the deformable pressing block 4. A plurality of protrusions 8 are provided at the bottom end of the deformable pressing block 4. The inverted "J"-shaped support plate 3 is respectively provided with two groups of circular through holes, and the circular through holes are provided in the middle part of the inverted "J"-shaped support plate 3, which are penetrated by the U-shaped bolt 1. The protrusions 8 on the bottom surface of the deformable pressing block 4 are in the shape of multiple rows of tiny canine teeth, and the protrusions 8 press the top of the frame of the photovoltaic component 6. The U-shaped bolt 1 is connected to the steel strand 2, the inverted "J"-shaped support plate 3, the two fastening nut combinations 5, the deformable pressing block 4, and the fastening nut combination 5 includes a flat washer, a spring washer, and a nut.

[0028] Bolts 9 are inserted between the bottom fixing frame of the photovoltaic component 6 and the inverted "X"-shaped support plate 3. The photovoltaic component 6 is placed close to the limiting block 7 and placed on both sides of the inverted "X"-shaped support plate 3, and connected with bolts 9 to fix the photovoltaic component 6. The middle and upper parts of the U-shaped bolt 1 are threadedly fastened with a fastening nut combination 5. Tighten the first group of fastening nuts 5 to firmly connect the U-shaped bolt 1 and the inverted "X"-shaped support plate 3. The upper surface ends of the inverted "X"-shaped support plate 3 are fixedly connected to the limiting block 7, and the limiting block 7 and the photovoltaic component 6 are in contact with each other. The limiting block 7 can be used to contact the photovoltaic component 6, which is convenient for contact limiting. The inside of the U-shaped bolt 1 is penetrated by a steel strand 2, and the upper part of the steel strand 2 is in contact with the bottom of the inverted "X"-shaped support plate 3.

[0029] Working principle: first clamp the U-bolt 1 on the steel strand 2, then fix the inverted "X"-shaped support plate 3 on the U-bolt 1 with the first set of fastening nuts 5, and tighten the first set of fastening nuts 5 to firmly connect the U-bolt 1 and the inverted "X"-shaped support plate 3 together.

[0030] Then, the photovoltaic assembly 6 is placed close to the limiting block 7 on both sides of the inverted "X"-shaped support plate 3 , and connected with bolts 9 to fix the photovoltaic assembly 6 .

[0031] Finally, the deformable pressing block 4 is put onto the U-shaped bolt 1 , and the top is pressed to the upper edge of the frame of the photovoltaic component 6 , and the second set of fastening nuts 5 are tightened and fixed on the U-shaped bolt 1 , so that the deformable pressing block 4 presses the photovoltaic component 6 .

[0032] When the cable structure undergoes displacement changes under normal working conditions, the steel strand 2 bends and the displacement is transmitted through the inverted “X”-shaped support plate 3. Since the inverted “X”-shaped support plate 3 is elastic and can consume part of the kinetic energy, further, the photovoltaic module 6 supported by the inverted “X”-shaped support plate 3 is not tightly attached to the steel strand 2, thereby avoiding the problem of hidden cracks in the photovoltaic module 6 caused by the displacement of the steel strand 2.

[0033] When the displacement is transmitted to the deformable pressing block 4 through the U-bolt 1, the inverted L-shaped parts on both sides thereof can be deformed, and the kinetic energy brought by the vibration of the steel strand 2 is consumed under the condition of ensuring the free deformation between the photovoltaic modules 6, thereby reducing the risk of hidden cracks in the photovoltaic modules 6. Furthermore, when the deformable pressing block 4 is deformed, the inverted L-shaped part forms a self-locking, and the photovoltaic modules 6 will not loosen or fall off due to its own deformation. During the overall working process, the safety and stable operation of the photovoltaic modules 6 are guaranteed.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
