[0033] Specifically, in an alternative embodiment, as shown in Figure 1 The flexible photovoltaic support includes four bearing ropes 105 divided into two groups, and each group of bearing ropes 105 is used for installing a single-row photovoltaic module; the bearing ropes 105 pass through the buckle holes of the U-shaped buckles installed on the middle column rotation shaft beam 202.

[0034] That is, the four bearing ropes 105 corresponding to each middle column rotation shaft beam 202 can be installed with two rows of photovoltaic modules, and the above-mentioned double-row structure can meet the design requirements of a larger span. Due to the characteristics of the flexible support, various terrains such as mountains, Gobi, farmland, and fishing grounds can be met.

[0035] Specifically, in an alternative embodiment, the other end of the front middle column traction rope 2041 is tied to the fixed middle column traction rope buckle on the middle column rotation shaft arc disc 203; the other end of the rear middle column traction rope 2042 is tied to the fixed middle column traction rope buckle on the middle column rotation shaft arc disc 203.

[0036] Specifically, in an alternative embodiment, as shown in Figure 4 The middle column rotation shaft beam 202 and the middle column 201 are rotationally connected in the following manner: the middle column 201 is divided into a left steel column 2061 and a right steel column 2062, a left fixed plate 2063 and a right fixed plate 2064 are respectively arranged on the left side of the left steel column 2061 and the right side of the right steel column 2062, the outer surface of a middle column outer sleeve is fixed with the middle column rotation shaft beam 202, the inner tube of the middle column outer sleeve is sleeved into a middle column lining pipe, the inner tube of the middle column lining pipe is inserted into a middle shaft 209, and the two ends of the middle shaft 209 are respectively inserted into the pin holes of the left fixed plate 2063 and the right fixed plate 2064 after passing through the left steel column 2061 and the right steel column 2062.

[0037] Specifically, in an alternative embodiment, as shown in Figures 3-4As shown, the bottom of the left steel column 2061 and the right steel column 2062 of the middle column 201 is fixed with the middle column column support 2066, and the top of the left steel column 2061 and the right steel column 2062 of the middle column 201 is fixed with the middle column top plate 2065; the bottom of the middle column column support 2066 is fixed with the middle column precast pipe pile 2067.

[0038] The middle column rotating mechanism is composed of the middle column rotating shaft beam 202, the middle column rotating shaft arc disc 203, the front and rear middle column traction ropes 2041 and 2042. The middle column rotating shaft beam 202 can be flexibly selected according to the local wind and snow pressure adjustment by selecting different specifications of square steel pipes. The middle column rotating shaft beam 202 directly supports two single-row photovoltaic modules within the allowable inclination angle range, so it mainly bears the additional load of the photovoltaic modules.

[0039] The left steel column 2061, the right steel column 2062 and the middle column top plate 2065 form an upper I-shaped steel column. The middle column rotating shaft beam 202 is connected to the upper I-shaped steel of the middle column 201 by a shaft pin to form a restriction degree, allowing only circular motion around the normal direction of the shaft pin. The front and rear pulley supports 2043 and 2044 are welded at the lower end position of the left steel column 2061 or the right steel column 2062.

[0040] The other ends of the front and rear middle column traction ropes 2041 and 2042 are buckled on the middle column traction rope buckles reserved on the middle column rotating shaft arc disc 203, forming a controllable "transmission" structure. By controlling the reciprocating displacement of the transverse driving cable 1070, the displacement difference of the front and rear middle column traction ropes 2041 and 2042 is formed, so that the middle column rotating shaft beam 202 forms the expected inclination angle to meet the inclination angle control of the whole row of modules.

The movement torque of each part is transmitted by flexible cables, and the force transmission direction is changed by the cooperation of the front and rear pulleys 2045 and 2046. The flexible transverse driving cable 1070 penetrates through each row of arrays. The front and rear middle column traction ropes 2041 and 2042 in a single middle column structure change the direction of motion by the front and rear pulleys 2045 and 2046.

By arranging the front and rear oil pipe clamps 2071, 2072, the transverse driving cable 1070 is further limited in position, so that it is only movable in the left-right direction.

[0043] Specifically, in an optional embodiment, as shown in Figure 2 As shown, the center column rotating shaft arc plate 203 is connected with the two edge portions of the center column rotating shaft beam 202 with a first center column reinforcing pipe 2081 and a fourth center column reinforcing pipe 2084 respectively, and the middle portion of the center column rotating shaft arc plate 203 is connected with the center column rotating shaft beam 202 with a second center column reinforcing pipe 2082 and a third center column reinforcing pipe 2083, and the first center column reinforcing pipe 2081, the second center column reinforcing pipe 2082 and the center column rotating shaft beam 202 form a triangle, and the third center column reinforcing pipe 2083, the fourth center column reinforcing pipe 2084 and the center column rotating shaft beam 202 form a triangle. By arranging this form of reinforcing structure, the center column rotating shaft arc plate 203 and the center column rotating shaft beam 202 are more stable, and the rotating shaft beam is not easy to be deformed by the load cable 105.

[0044] Specifically, in an optional embodiment, as shown in Figure 2 As shown, the center column rotating shaft arc plate 203 and the center column rotating shaft beam 202 are further connected with at least one fifth center column reinforcing pipe 2085. By arranging this form of reinforcing structure, the center column rotating shaft arc plate 203 and the center column rotating shaft beam 202 are more stable, and the center column rotating shaft beam 202 is not easy to be deformed by the load cable 105.
