The photovoltaic flexible bracket can be a flexible fixed bracket, and the inclination angle of the photovoltaic module on the flexible fixed bracket is fixed. It can also be a flexible fixed adjustable bracket with adjustable inclination angle. The photovoltaic module of the flexible bracket with adjustable inclination angle can adjust the inclination angle according to the season, or it can also be a flexible tracking bracket. The tracking angle of the photovoltaic module is adjusted in real time according to the azimuth of the sun. The photovoltaic flexible bracket specifically includes columns, and multiple columns are arranged at intervals on the base surface. The base surface can be the top of a building, a plain, a hill, a mountain, a lake, a desert, a next door, etc., which can be illuminated by sunlight. The present invention does not limit the base surface.

[0056] In this embodiment, the support truss 43 is preferably an angle steel, and the four corners of the support truss 43 are connected to the cable by U-bolts, and the stability and anti-deformation ability of the support truss 43 are ensured by the cross-arranged intermediate trusses 433. Preferably, the distance between the corner point on the lower truss 432 connected to the stabilizing cable 42 and the plane of the photovoltaic module 9 carrier body is uniformly changed so that the stabilizing cable 42 is in an upward concave arch shape.

The stabilizing cable 42 passes through the fixing part 81 at the bottom of the first beam 71 or the second beam 72 and is fixed by the wire clamp 82.

[0058] In this embodiment, by providing a fixing member 81 and a wire clamp 82, the anti-falling ability of the load-bearing cable 41 and the stabilizing cable 42 is improved, the stress concentration at the ends of the first beam 71 and the second beam 72 is weakened, and the risk of cable falling off and beam deformation caused by stress concentration is reduced.

[0059] refer to Figure 1 , Figure 2 On the basis of the above-mentioned embodiment, the first mounting seat 61 and the third mounting seat 63 are provided with a driving device 10, and the output ends of the multiple driving devices 10 are respectively connected to the corresponding first beam 71 or the second beam 72, and the multiple driving devices 10 synchronously drive the first beam 71 and the second beam 72 to rotate and drive the photovoltaic component 9 on the carrier to rotate.

[0060] In this embodiment, the first mounting seat 61 and the third mounting seat 63 are preferably both provided with a bottom plate and a support plate vertically and parallelly arranged on the bottom plate, and the two support plates and the bottom plate form an accommodating cavity, and the driving device 10 and the first beam 71 or the second beam 72 are arranged in the accommodating cavity. In the accommodating cavity of the first mounting seat 61, the driving device 10 is arranged on the support plate close to the third mounting seat 63, and the first beam 71 is arranged at the output end of the driving device 10; in the accommodating cavity of the third mounting seat 63, the driving device 10 is arranged on the support plate on either side, and the second beam 72 is arranged at the output end of the driving device 10.

The bolts pass through the through holes of the support plate, the driving device, the first beam 71 or the second beam 72, so that the force of the housing of the driving device 10 acting on the support plate is transmitted to the other corresponding support plate through the bolts, so that the two support plates are jointly subjected to force, thereby avoiding local stress concentration on the first mounting seat 61 and the third mounting seat 63, causing small deformation on the first mounting seat 61 and the third mounting seat 63, and facilitating improving the bearing capacity of the first mounting seat 61 and the third mounting seat 63.

The bolts connecting the support plate pass through the inside of the sleeves, and one end of the sleeve is inserted into the bearing cavity and can rotate around the axis of the through hole on the support plate. By providing the bearing and the sleeve, the bolt only needs to bear the tensile force and does not need to bear the vertical shear force. The stress state is simple, and the risk of damage to the bolt under a complex stress state is eliminated. At the same time, the sleeve and the bearing can reduce the deformation of the first mounting seat 61 and the third mounting seat 63 and the friction between the first beam 71 and the second beam 72 and the through hole on the support plate when they rotate, so that the rotation is stable and smooth.
