[0027] like Figure 1 As shown, this embodiment provides a support assembly for tilting a solar module 6 onto a cable 5, including a first support member 1 and a second support member 2. The first support member 1 includes a first mounting plate 11 for connecting to the solar module 6, a first fixing plate 12 for fixing to the steel cable 5, and a first connecting member for connecting the first mounting plate 11 and the first fixing plate 12. The second support member 2 includes a second mounting plate 21 for connecting to the solar module 6, a second fixing plate 22 for fixing to the steel cable 5, and a second connecting member for connecting the second mounting plate 21 and the second fixing plate 22. The support height of the first support member 1 is less than the support height of the second support member 2. By using the first support member 1 and the second support member 2 in combination, this embodiment can achieve the fixing of the solar module 6 onto the steel cable 5 at a certain tilt angle, which can effectively increase the amount of solar radiation received by the module per unit time, thereby increasing the power generation of the solar module 6. Moreover, the first support member 1 and the second support member 2 have simple structures and low manufacturing costs.

[0028] In this embodiment, the support height of the first support member 1 is the height between the position where the first fixing plate 12 is fixed to the steel cable 5 and the position where the first mounting plate 11 is connected to the solar module 6, and the support height of the second support member 2 is the height between the position where the second fixing plate 22 is fixed to the steel cable 5 and the position where the second mounting plate 21 is connected to the solar module 6.

[0029] Furthermore, both the first mounting plate 11 and the second mounting plate 21 are arranged horizontally, while both the first fixing plate 12 and the second fixing plate 22 are arranged vertically. The horizontal arrangement of the first mounting plate 11 and the second mounting plate 21 facilitates the fixing of the solar module 6; the vertical arrangement of the first fixing plate 12 and the second fixing plate facilitates the fixing to the steel cable 5.

[0030] In some embodiments, the first connector includes two first connecting plates 13, the lower ends of which are connected to the upper ends of the first fixing plate 12, and the upper ends of which are respectively connected to the two ends of the first mounting plate 11. Figure 1 As shown, the lower ends of the two first connecting plates 13 are connected to the upper ends of the first fixing plate 12, and the upper ends of the two first connecting plates 13 are respectively connected to the two ends of the first mounting plate 11, forming an inverted triangular support structure, which can improve the stability and reliability of the first support member 1; and the included angle of the two first connecting plates 13 is an obtuse angle, which makes the stress distribution more uniform when the structure is under force, reduces stress concentration, thereby extending the service life of the first support member 1 and reducing the risk of structural failure.

[0031] In some embodiments, the second connector includes two second connecting plates 23, the lower ends of which are connected to the upper ends of the second fixing plate 22, and the upper ends of which are respectively connected to the two ends of the second mounting plate 21. Figure 1 As shown, the lower ends of the two second connecting plates 23 are connected to the upper ends of the second fixing plate 22, and the upper ends of the two second connecting plates 23 are respectively connected to the two ends of the second mounting plate 21, forming an inverted triangular support structure, which can improve the stability and reliability of the second support member 2; and the included angle of the two second connecting plates 23 is an acute angle, which can increase the support height of the second support member 2.

[0032] In the optimized embodiment above, the first support member 1 and the second support member 2 are both integrally molded. Since both the first support member 1 and the second support member 2 are integrally molded, they can be manufactured in a factory, eliminating the need for on-site assembly. This facilitates on-site operation, significantly improves on-site construction efficiency, and eliminates the stress concentration issues associated with connecting parts found in assembled components, resulting in higher stability and reliability.

[0033] Furthermore, both ends of the first mounting plate 11 and both ends of the second mounting plate 21 are provided with first connection holes 3 for connecting to the solar module 6. Figure 1As shown, the connection points between the upper ends of the two first connecting plates 13 and the first mounting plate 11 are located between the two first connecting holes 3 of the first mounting plate 11 and are respectively close to the two first connecting holes 3; the connection points between the upper ends of the two second connecting plates 23 and the second mounting plate 21 are located between the two first connecting holes 3 of the second mounting plate 21 and are respectively close to the two first connecting holes 3.

[0034] Furthermore, both the first fixing plate 12 and the second fixing plate 22 are provided with two second connecting holes 4 for fixing to the steel cable 5. Figure 1 As shown, the two second connecting holes 4 on the first fixing plate 12 are used to fix the steel cable 5 with U-bolts 7. The height between the bottom of the upper second connecting hole 4 on the first fixing plate 12 and the first mounting plate 11 is the support height of the first support member 1. The two second connecting holes 4 on the second fixing plate 22 are used to fix the steel cable 5 with U-bolts 7. The height between the bottom of the upper second connecting hole 4 on the second fixing plate 22 and the second mounting plate 21 is the support height of the second support member 2.

[0035] This embodiment also provides a solar power generation system, including several solar power generation units. Each solar power generation unit includes two parallel steel cables 5 and several solar modules 6 spaced apart along the length of the steel cables 5. It also includes any of the aforementioned support components. One end of each solar module 6 is fixed to the two steel cables 5 via two first support members 1, and the other end of each solar module 6 is fixed to the two steel cables 5 via two second support members 2. This embodiment, through the combined use of the first support members 1 and the second support members 2, enables the solar modules 6 to be fixed at a certain angle on the steel cables 5, effectively increasing the amount of solar radiation received by the modules per unit time and improving the power generation of the solar modules 6. Furthermore, the four-point fixing method of the solar modules 6 using two first support members 1 and two second support members 2 makes the connection between the solar modules 6 and the steel cables 5 more reliable, and can flexibly adapt to various different tilting fixations of the solar modules 6 on the cables, exhibiting good versatility and adaptability.

[0036] Furthermore, the solar module 6 includes a solar panel and a frame 61 for fixing the solar panel. The frame 61 is connected to the first mounting plate 11 and the second mounting plate 21 by bolts 7. Furthermore, the frame 61 includes two oppositely arranged first sides and two oppositely arranged second sides, and at least two of the first sides have a base plate at their bottom for connecting to the first support member 1 or the second support member 2. The base plate has two holes corresponding to the positions of each of the first support member 1 or each of the second support members 2.

[0037] like Figure 2and Figure 3 As shown, one of the first side ends is connected to the first mounting plate 11 of the two first support members 1 by four bolts 7, and the bolts 7 pass through the corresponding holes on the first side and the corresponding first connecting holes 3 on the first mounting plate 11 and are fixed by nuts; Figure 2 and Figure 4 As shown, the two ends of the other first side are connected to the second mounting plates 21 of the two second support members 2 by four bolts 7, and the bolts 7 pass through the corresponding holes on the second side and the corresponding first connecting holes 3 on the second mounting plate 21 and are fixed by nuts; wherein, the bolts 7 can be hexagonal bolts, and washers can also be set between the nut and the first mounting plate 11 and between the nut and the second mounting plate 21.

[0038] In some embodiments, the first fixing plate 12 and the second fixing plate 22 are respectively fixed to the steel cable 5 by U-bolts 8, and the two studs of the U-bolt 8 pass through the first fixing plate 12 or the second fixing plate 22 and are fixed by nuts 9. The steel cable 5 is fixed between the arc-shaped part of the U-bolt 8 and the first fixing plate 12 or the second fixing plate 22. During installation, the steel cable 5 is clamped at the arc-shaped part of the U-bolt 8, and the two studs of the U-bolt 8 pass through the first fixing plate 12 of the first support member 1 or the second fixing plate 22 of the second support member 2. Then, the nuts 9 are tightened. As the nuts 9 are tightened, the arc-shaped part of the U-bolt 8 will gradually move closer to the fixing plate and generate sufficient clamping force, thereby fixing the first fixing plate 12 of the first support member 1 or the second fixing plate 22 of the second support member 2 to the steel cable 5. This not only makes installation and disassembly convenient and can effectively improve the construction efficiency of the system, but also ensures a firm and reliable connection that can withstand greater tension and vibration, ensuring that the first support member 1 and the second support member 2 can be stably fixed on the steel cable 5.

[0039] like Figure 3 As shown, the two studs of the U-bolt 8 pass through the two second connecting holes 4 on the first fixing plate 12 and are fixed by nuts 9. The arc-shaped part of the U-bolt 8 and the first fixing plate 12 form a space for fixing one of the steel cables 5. Figure 4 As shown, the two studs of the U-bolt 8 pass through the two second connecting holes 4 on the second fixing plate 22 and are fixed by the nut 9. The arc-shaped part of the U-bolt 8 and the second fixing plate 22 form a space for fixing another steel cable 5. Washers can also be placed between the nut 9 and the first fixing plate 12 and between the nut 9 and the second fixing plate 22 to enhance the stability and reliability of the connection and prevent loosening.

[0040] In this embodiment, each solar power generation unit further includes columns at both ends. Each column has a crossbeam at its top. One end of each of the two steel cables 5 is connected to both ends of the crossbeam at one end, and the other end of each steel cable 5 is connected to both ends of the crossbeam at the other end. The bottom of each column is fixed to a column foundation, which is buried below ground level. Furthermore, the top of each column is also fixed to the ground by inclined anchors.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
