Description
Technical Field
The invention belongs to the field of photovoltaic power generation, and particularly relates to a self-anchored polygonal photovoltaic support system.
Background
The traditional strip-shaped photovoltaic support is in a bent frame form. A plurality of bent cold-formed steel frames are arranged in the short direction of the strip photovoltaic support structure, namely in the transverse direction of the structure. And at the top end of the frame, a continuous purline is arranged in the longitudinal direction of the elongated strip-shaped photovoltaic support structure, namely the longitudinal direction of the structure, so as to support the photovoltaic assembly. This form is simple in construction, design, manufacture and installation and was originally applied to flat gobi terrain.
With the development of the photovoltaic industry, the method is also gradually applied to hilly and mountain lands and photovoltaic composite projects such as agriculture light complementation, forest light complementation, pasture light complementation and fishing light complementation. But for the photovoltaic composite project with large span and large space requirement under the assembly, the steel consumption is large. With the larger lower space requirements of composite projects, the technical economics of such structures have gone beyond reasonable limits. A traditional photovoltaic support in a bent frame form is similar to a single-layer industrial factory building and is a straight strip-shaped structure system formed by mutually connecting plane structures. In the case of a relief, both construction and application are difficult. The continuous purline for supporting the photovoltaic module is of a continuous beam statically indeterminate structure in mechanics. In unfavorable geological environment such as soft foundation, colliery subsidence district, the uneven settlement of basis can cause this kind of hyperstatic structure support to subside, causes the purlin distortion to warp and exceeds extreme condition, and the photovoltaic module on the purlin is buckled and is destroyed.
Flexible photovoltaic supports that have emerged in the last two years use a structure of cables of the strip type supported on uprights or flat frames. The horizontal supporting system is a bearing cable parallel to the length direction, and the photovoltaic support is fixed on the bearing cable. The bearing cable with the length of about dozens of meters to hundreds of meters can be supported by vertical components such as upright posts or plane frames to form a plurality of spans, and is similar to an overhead transmission line. These columns or flat frames are generally designed to bear the weight of the cable only, and not the tension of the cable. At both ends of the bearing cable, a firm supporting structure bears huge cable tension, and the cable tension is transmitted to the foundation by the foundation. The stability of the bearing cable depends on a stabilizing cable in the vertical length direction or a plurality of downward anchor cables in the span of the bearing cable. The flexible photovoltaic support needs to be firmly fixed by the bearing cables, the stabilizing cables and the anchor cables, and transmits the cable tension to the foundation and the foundation, so that the flexible photovoltaic support requires relatively solid foundation conditions and is difficult to adapt to unfavorable geological environments such as a soft foundation, a coal mine subsidence area and the like. The continuous collapse resistance of the support in the length direction is weak, and the damage of the end part, the middle support or the bearing cable at any position can cause the failure of the integral cable structure support system with the length of about dozens of meters to hundreds of meters, thus causing the continuous collapse of the support.
At the present stage, the photovoltaic projects are flat-price projects, and on the premise of ensuring the profitability of owners, the costs of land, components, booster stations, outgoing lines and the like are deducted, so that little charge is left for photovoltaic supports and basic parts. And then the geological conditions, typhoons, sea waves and agricultural policy influences of project site areas are superposed, and the selection faces of the photovoltaic support and the basic technical scheme are very limited, so that the project can be facilitated by breaking through the conventional method and meeting safe, reliable, economic and applicable conditions.
