The utility model aims to overcome current flexible support structure span is big, vibrates serious shortcoming under the wind load effect, provides a flexible photovoltaic supporting structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:

a flexible photovoltaic support structure comprises two rows of pile foundations and a plurality of photovoltaic panels, wherein the pile foundations are arranged oppositely, steel columns are arranged on the pile foundations at two ends, steel beams are erected at the upper ends of the steel columns, inhaul cables are arranged between the steel beams, each photovoltaic panel is fixed on the inhaul cables through 4 connecting pieces, and elastic gaskets are arranged in the connecting pieces;

an earth anchor is arranged below each inhaul cable, a damping rod is arranged in each inhaul cable span, and the other end of each damping rod is connected with the corresponding earth anchor;

and each span end is provided with a wind resisting cable, one end of the wind resisting cable is connected with the inhaul cable, and the other end of the wind resisting cable is connected with the steel column.

Furthermore, every cluster of subassembly of cable establishes two altogether, and the tip of every is provided with the anti-wind cable.

Furthermore, the inhaul cable adopts a prestress steel strand, and is fixed on the steel beam after being tensioned by applying prestress.

Further, the damping rod adopts a spring or a viscous damper.

Further, the pile foundation is a reinforced concrete cast-in-place pile or a prestressed concrete pipe pile.

Further, steel upright and steel beam adopt steel structure H shaped steel.

Further, the ground anchor adopts concrete or steel structure stub.

Compared with the prior art, the utility model discloses following beneficial effect has:

the flexible photovoltaic support structure of the utility model adds the damping rod and the wind resisting cable, which can greatly reduce the structure amplitude; the connecting piece adopts elastic support, reduces the transmission force of structural vibration to the photovoltaic panel, ensures that the photovoltaic panel can not be hidden and broken, and ensures that the structure is safer and more reliable, economic and reasonable.

Furthermore, the prestressed steel strand is used as a main supporting structure of the flexible support, so that the damping force of the structure is increased, and the structure is guaranteed against special wind-induced disasters.
