The number of the first connecting pieces 301 is at least two, and the first connecting pieces 301 are used for installing the photovoltaic panel 4, and two ends of each first connecting piece 301 are connected with any two columns 1 of the plurality of columns 1 through the lifting assembly 2 respectively so as to adjust the angle of the photovoltaic panel 4 under the driving of the lifting assembly 2.
For example, as shown in fig. 1 and fig. 2, an external thread is provided on the outer periphery of the rotor 201, the external thread of the rotor 201 forms a second meshing portion 2011, a plurality of saw teeth arranged in the up-down direction are provided on the column 1, the plurality of saw teeth form a first meshing portion 1061, the axis of the rotor 201 is arranged in the up-down direction, and the rotor 201 is rotatably connected to the first meshing portion 1061 around its own axis. The pitch of the external screw thread of rotor 201 and the pitch phase adaptation of sawtooth to rotor 201 when rotating, rotor 201 drive lifting unit 2 and move along the upper and lower direction on stand 1 under the effect of first meshing portion 1061, and lifting unit 2 drives first connecting piece 301 when moving in the upper and lower direction, with the inclination of adjusting first connecting piece 301 and horizontal plane, thereby realizes the angle modulation of the photovoltaic board 4 of first connecting piece 301.
The fact that at least a part of the rotor 201 is made of a magnetic material means that the entire rotor 201 is made of a magnetic material, or a part of the rotor 201 may be made of a magnetic material, and the N pole and the S pole of the rotor 201 are arranged opposite to each other in the radial direction of the rotor 201 (as shown in fig. 3 and 4).

Therefore, the rotating flexible photovoltaic support 100 of the embodiment of the invention has the advantages of convenience in angle adjustment of the photovoltaic panel 4 and the like.
In some embodiments, the plurality of posts 1 includes a first set of posts including first posts 101 and second posts 102 spaced apart along a first direction, and a second set of posts including third posts 103 and fourth posts 104 spaced apart along the first direction, the first and second sets of posts being disposed along a second direction, the first direction being orthogonal to the up-down direction, the second direction being orthogonal to the up-down direction, the first direction being at an angle to the second direction.

In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking as an example that the first direction coincides with the east-west direction and the second direction coincides with the north-south direction, wherein the east-west direction and the north-south direction are shown in fig. 1.
For example, as shown in fig. 1, the first upright 101 is located west of the second upright 102, and the third upright 103 is located west of the fourth upright 104. The first group of columns is positioned on the north side of the second group of columns, the first column 101 and the third column 103 correspond to each other in the north-south direction, the second column 102 and the fourth column 104 correspond to each other in the north-south direction, and the highest position and the lowest position of the movement of the lifting assembly 2 on each column 1 are the same.

The initial length of the first connecting member 301 is the linear distance between the highest point of the lifting assembly 2 on the first upright 101 and the lowest point of the lifting assembly 2 on the fourth upright 104, plus the linear distance between the highest point and the lowest point of the lifting assembly 2 on the fourth upright 104, plus the connection distance between the lifting assembly 2 and the upright 1.
When the rotating flexible photovoltaic support 100 of the embodiment of the invention is used, for example, when the sun is at the south at 12:00 pm, the photovoltaic panel 4 needs to be changed from the inclined posture with the west high and east low to the inclined posture with the north high and south low (as shown in fig. 1), the coils 502 on the stators 501 on the second upright 102 and the third upright 103 are sequentially energized to rotate the rotor 201, so that the lifting assembly 2 on the second upright 102 rises and the lifting assembly 2 on the third upright 103 descends at the same speed as the lifting assembly 2 on the second upright 102, the lifting assembly 2 on the second upright 102 rises to the same height as the lifting assembly 2 on the first upright 101, and the lifting assembly 2 on the third upright 103 descends to the same height as the lifting assembly 2 on the fourth upright 104. As shown in fig. 6, the first connecting member 301 connected between the second vertical column 102 and the third vertical column 103 is changed from the inclined state shown by the dotted line to the inclined state shown by the solid line, so that the length difference of the first connecting member 301 generated by the movement of the lifting assembly 2 in the up-down direction forms an equal triangle, and the lengths of the first connecting member 301 in the up-down direction of the second vertical column 102 and the third vertical column 103 are complemented with each other, so that the photovoltaic panel 4 assumes a north-south posture.
When the sun is at the west of 16:00 pm, the photovoltaic panel 4 needs to be changed from the inclination posture of north high, south low (as shown in fig. 1) to the inclination posture of east high, west low, the coils 502 on the stators 501 on the first upright column 101 and the fourth upright column 104 are respectively electrified in sequence to rotate the rotor 201, so that the lifting assembly 2 on the fourth upright column 104 rises and the lifting assembly 2 on the first upright column 101 descends at the same speed as the lifting assembly 2 on the fourth upright column 104, the lifting assembly 2 on the fourth upright column 104 rises to the same height as the lifting assembly 2 on the second upright column 102, the lifting assembly 2 on the first upright column 101 descends to the same height as the lifting assembly 2 on the third upright column 103, and the photovoltaic panel 4 presents the posture of north high, south low.
Therefore, the rotating flexible photovoltaic support 100 provided by the embodiment of the invention further facilitates the angle adjustment of the photovoltaic panel 4 by reasonably arranging the upright posts 1 and the first connecting pieces 301, so that the photovoltaic panel 4 can present different inclined postures according to different running tracks of the sun, the tracking of the photovoltaic panel 4 on the sun from east to west by 180 degrees is realized, and the photoelectric conversion effect of the photovoltaic panel 4 is improved.
