Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments of the utility model, and it should be understood that the utility model is not limited by the example embodiments described herein. Based on the embodiments described in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should fall within the protection scope of the utility model.

[0037] In order to adapt to complex installation terrain, in the related art, steel cables can be pulled by supports, and photovoltaic panels 30 are fixed on the steel cables to install the photovoltaic panels 30 to adapt to the ups and downs of the terrain. However, in this installation mode, the circumferential position of each support cannot be effectively guaranteed during installation, and the installation efficiency is low.

[0038] At the same time, since the steel cable needs to have a preset tensile stress load, if each support is relatively twisted, a large torque will be generated, which is prone to fatigue and other conditions, and is not conducive to improving the service life of the support.

[0039] Therefore, the utility model provides a flexible photovoltaic support, referring to Figures 1 to 7 The flexible photovoltaic support comprises: a plurality of support systems 10, the support system 10 comprises a column 11 and a crossbeam 12 rotationally connected with the column 11, the crossbeam 12 extends in the width direction, a plurality of steel cables 20 sequentially pass through each crossbeam 12 in the length direction and are fixed with two crossbeams 12 at both ends in the length direction respectively, and the steel cable 20 is used for installing the photovoltaic panel 30; the support system 10 further comprises a fixed base plate 13 and a connecting plate 14, the fixed base plate 13 is used for being fixed with a foundation 70, the inner ring part of the connecting plate 14 is fixed with the lower end of the column 11, the outer ring part of the connecting plate 14 has an arc-shaped hole 141 extending in the circumferential direction of the connecting plate 14, a first connecting piece 40 passes through the arc-shaped hole 141 and is connected with the outer ring part of the fixed base plate 13, so that the column 11 is relatively fixed with the fixed base plate 13, wherein before the first connecting piece 40 (for example, a bolt or the like) completely locks the connecting plate 14 with the fixed base plate 13, the connecting plate 14 can rotate relative to the fixed base plate 13 under the limiting action of the arc-shaped hole 141, so that the plurality of crossbeams 12 are parallel to each other.

[0040] Wherein, the width direction may be, for example, the direction in which the crossbeam 12 extends in the horizontal plane, and the length direction may be the direction perpendicular to the width direction in the horizontal plane. Referring to Figure 1 And Figure 4 The length direction may be the direction in which the steel cable 20 extends.

[0041] Wherein, the inner ring part may refer to the part with a smaller diameter, and the outer ring part may refer to the part with a larger diameter. It can be understood that the diameter of the inner ring part is smaller than the diameter of the outer ring part.

[0042] In the scheme of this embodiment, the steel cable 20 passes through each cross beam 12 and is fixed with the cross beams 12 at both ends in the length direction. For example, referring to Figure 1 and Figure 4 In the case of three support assemblies, one end of the steel cable 20 is fixed with the cross beam 12 of the left support assembly, the other end of the steel cable 20 passes through the cross beam 12 of the middle support assembly and is fixed with the cross beam 12 of the right support assembly.

It can be understood that in the case of each cross beam 12 being parallel to each other, after the installation of the steel cable 20 is completed, the situation that the cross beam 12 bears a torque due to the relative inclination of the cross beam 12 can be avoided, and the load received by the cross beam 12 can be balanced. Further, by providing the rotatable adjusting connecting plate 14, the angle of the cross beam 12 can still be adjusted after the pouring of the foundation 70 is completed, thereby avoiding the situation that the cross beam 12 is deflected due to the angle error during the pouring of the foundation 70, and reducing the requirement for the pouring precision of the foundation 70.

[0047] In this scheme, the fixing rib 61 and the fixed plate 50 can be pre-buried in the concrete-poured foundation 70, and during installation, the fixed base plate 13 is pressed against the fixed plate 50 by the fastening nut 62, so that the fixed base plate 13 is relatively fixed with the foundation 70.

[0048] In a possible implementation, the support system 10 further comprises a transmission rod 15 rotatably arranged on the column 11 and extending in the length direction; a transmission plate 16 fixedly connected with the cross beam 12, the transmission plate 16 being in transmission connection with the transmission rod 15; a connecting rod assembly, the transmission rods 15 of two adjacent support systems 10 being connected through the connecting rod assembly; and the flexible photovoltaic support further comprises a driving device 80 (for example, a motor), the driving device 80 being in transmission connection with the transmission rod 15 (for example, through gear transmission, chain wheel transmission, etc.).

[0049] In this scheme, the driving device 80 drives the transmission rod 15 to rotate, and the transmission rods 15 of different support assemblies are connected through the connecting rod assembly to realize power transmission. In this way, the driving device 80 can drive the transmission rods 15 of multiple support assemblies to rotate. The transmission plate 16 is in transmission connection with the transmission rod 15, and in the process of rotation of the transmission rod 15, the photovoltaic panel 30 can be driven to rotate through the transmission plate 16 to adjust the angle of the photovoltaic panel 30.
