[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0031] Traditional photovoltaic support structures are mostly rigid supports, which are composed of front columns, rear columns, beams, purlins and other components, which are connected to each other through connectors and bolts. However, this rigid support structure has problems such as small span, low bottom space utilization, large number of foundations, large amount of vegetation damage and large amount of steel consumption. It is not suitable for distributed photovoltaic projects that have large span requirements or require high bottom space utilization. Large-span flexible support is an innovative photovoltaic support structure with the characteristics of large span, high clearance and less consumables. It usually uses prestressed steel wire rope or steel strand to tension between the two fixed points. The two fixed points use rigid structures and outer inclined steel strands to provide support reaction force, which can achieve a span of 10 to 30 meters or even larger, and the span range is relatively flexible and adjustable.

[0032] The existing flexible support column structure will produce a torque phenomenon: the two points of force are not intersected at the same point, and the greater the interval between the two force points, the greater the torque generated, which will cause the structure to deform and affect the service life of the column. If the extension lines of the forces acting on both ends of the object converge to one point, then the sum of the torques of the two forces on the point is zero, thereby eliminating the torque. This is because the torque is equal to the force multiplied by the lever arm. When the line of action of the force passes through the same point, the lever arm is zero, so the torque is also zero. The large-span flexible support side column structure provided by the present application, a plurality of first steel wire ropes and a second steel wire rope are respectively located on both sides of the column body, and a plurality of first steel wire ropes and a second steel wire rope are located in the same vertical plane, a plurality of first steel wire ropes pass through the steel rope hole and are fixed, the second steel wire rope is connected to the steel rope connection assembly, and the extension line of the second steel wire rope passes through the center of the steel rope hole, so that the forces at both ends of the column body converge to one point, thereby eliminating the torque and improving the service life of the column.
