Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a flexible support triangular structure strut system. Background Technology

[0002] Flexible photovoltaic (PV) supports have gained increasing attention and application due to their advantages such as large span, high efficiency in utilizing material mechanical properties, and low cost. Flexible PV supports are adaptable to various complex installation environments, including mountains, water surfaces, and rooftops, and are equipped with cables.

[0003] Flexible photovoltaic (PV) support structures bear gravity loads, wind loads, and snow loads, which are then transferred to the cable structure. In most scenarios, wind and snow loads are far greater than gravity loads. Currently, most flexible PV support structures are single-layer cable structures. While these can effectively withstand the vertical gravity and snow loads of the modules, their high sag design limits their ability to withstand wind loads and negative wind pressure (wind acting on the modules, creating an upward lifting force). Pulsating wind pressure can cause significant vibrations in the cable structure, including flutter and galloping, which can even lead to damage in severe cases. Furthermore, single-layer cable structures, due to the requirement for a certain sag in the cables and their limited load-bearing capacity, are unsuitable for scenarios with large wind loads and small spans.

[0004] Therefore, the existing single-layer cable structure of flexible photovoltaic support has the following disadvantages: poor resistance to negative winds; prone to wind-induced vibration, including flutter and galloping; and large structural deformation under wind and snow loads, which can easily cause serious damage such as component detachment, tensile cracking, and hidden cracks. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to propose a flexible support triangular structure strut system to improve the stability of the support and reduce its swaying.

[0006] To achieve the above objectives, this utility model proposes a flexible support triangular structure strut system, including:

[0007] A bracket unit, wherein multiple bracket units are configured, the bracket units are arranged adjacent to each other, and adjacent bracket units are fixedly connected, and the upper end of the bracket unit is used to mount photovoltaic modules;

[0008] Component cable, the component cable is arranged laterally on the upper end of the support unit, and each support unit is provided with the component cable on its upper end;

[0009] A load-bearing cable is provided at the lower end of the support unit in a transverse direction, and each support unit is provided with a load-bearing cable at its lower end.

[0010] A connecting cable is longitudinally arranged at the lower end of the support unit. The connecting cable is sequentially connected to the lower end of the support unit and intersects with the component cable and the load-bearing cable respectively.

[0011] According to the flexible support triangular structure strut system of this utility model embodiment, the component cable is arranged laterally at the upper end of the support unit, and each support unit has a component cable at its upper end. The load-bearing cable is arranged laterally at the lower end of the support unit, and each support unit has a load-bearing cable at its lower end. The support unit is located between the component cable and the load-bearing cable, forming a double-layer cable truss cable net structure. This maintains the stability of the cable net structure, improves the stability of the support, further reduces the swaying of the component cable and the load-bearing cable in the horizontal and vertical directions, and improves the stiffness of the component cable and the load-bearing cable. When the component cable and the load-bearing cable are tensioned, the support unit can effectively offset the downward pressure brought by the component cable and the upward support force of the load-bearing cable through internal force transmission, forming a mutually offsetting internal force balance and increasing the stiffness between the component cable and the load-bearing cable.

The fixing component includes a first fixing member, a second fixing member, and a U-shaped screw. The first fixing member is fixed to one side of the support frame, and the second fixing member is fixed to the other side of the support frame opposite to the first fixing member. The U-shaped screw passes through the first fixing member, the support frame, and the second fixing member in sequence to fix the component cable in the U-shaped screw.

[0018] Specifically, the support frame is configured as a triangle.

[0019] Optionally, the support units are connected by a first connecting frame and a second connecting frame. The first connecting frame is V-shaped and is positioned opposite to the second connecting frame. One end of the first connecting frame is connected to the upper end of one of the support units to form a triangular support.
