Description

Technical Field

[0001] The utility model relates to a wind-resistant system, in particular to a flexible wind-resistant system. Background Art

[0002] Flexible photovoltaic support technology is being applied in more and more projects in mountainous areas, fishery-photovoltaic complementary scenarios, and other scenarios. Along with the demand for increasing the support span and improving the wind resistance and stability of the support, the double-layer cable truss structure is becoming a commonly used flexible support structure.

[0003] The component cables and load-bearing cables of the double-layer cable truss structure can be connected by a tripod or a tetrahedron, so that the component cables and the load-bearing cables can be deformed in coordination and bear the force together. However, by doing so alone, the overall wind resistance of the bracket is still insufficient. On the one hand, the three-cable structure has insufficient stiffness to resist lateral deformation and torsion. On the other hand, the three-cable structure deforms too much to resist wind suction loads because the load-bearing cables stop working under the action of wind suction, and the stiffness is still insufficient if the component cables with pre-tension are used alone.

[0004] The solution to the former is to connect the adjacent rows of flexible brackets into a whole to resist wind, and the solution to the latter is to set up cables to resist wind suction. Different projects have different solutions for connecting cables and setting up cables. For example, the component cables and load-bearing cables of adjacent rows of brackets are connected by X-shaped cross rods. This practice is common in fish-solar complementary projects, but it is difficult to apply to mountain projects. Utility Model Content
