Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and in particular relates to a photovoltaic flexible support truss-type side beam structure. Background Technology

[0002] With the development of photovoltaic construction, the application of flexible photovoltaic supports is gradually increasing, and the application scenarios are also becoming more diverse. At the same time, due to the scarcity of land resources, there is less and less land available for photovoltaic construction. Therefore, the issue of land utilization efficiency in photovoltaic construction has become a concern for photovoltaic builders.

[0003] Existing flexible support systems, due to their unique structural advantages, can traverse special terrains such as ravines and valleys, significantly improving land utilization compared to traditional fixed supports. However, there is still room for improvement in certain areas. Flexible support systems require stay cables on their side beams. For optimal stress distribution, the stay cables are typically angled at 45 degrees. Since the side beams of a flexible support system are usually 4.5 meters above the ground, and the 45-degree angle requires anchor piles to be 4.5 meters away from the side beams, this distance must be within the land boundary. However, this location is currently unsuitable for installing photovoltaic modules. Because both ends of the flexible support system have stay cables and anchor piles, approximately 45 meters of land at both ends of each row of flexible modules cannot be used for photovoltaic module installation.

[0004] Therefore, a photovoltaic flexible support truss-type side beam structure needs to be designed to solve the above problems. Utility Model Content

[0022] Definitions:

[0023] Flexible support structure: This refers to a photovoltaic support structure with an east-west span of more than 8 meters, where flexible steel cables support the photovoltaic modules between the columns. The two ends of the steel cables are fixed to the two outermost crossbeams, and tension is applied to keep the cables taut. Photovoltaic modules are then installed on the taut cables. This type of support structure allows for some sag in the middle of the cables and permits slow swaying under wind load conditions, hence the name "flexible support structure."

[0024] Large span: This refers to a photovoltaic (PV) support structure with an east-west column span exceeding 30 meters. Correspondingly, there are medium spans of 16-20 meters and small spans of 6-9 meters. The advantages of a large span are: reduced number and density of ground piles, facilitating mechanized agricultural operations beneath the PV panels; the disadvantages are reduced rigidity of the supporting components, leading to a tendency for downward deformation under wind and snow loads, or wind-induced vibration. Currently, small span supports are difficult to adapt to agricultural planting requirements, while large span supports present cost and safety issues. Medium span supports are gradually gaining market acceptance. However, in some special situations where intermediate piling is not permitted, large spans are still necessary.

[0025] Prestressing: To improve the rigidity of the overall structure, tensile or compressive forces are applied in advance during construction, thereby generating stress inside the component in advance to partially or completely offset the stress caused by external loads and avoid excessive deformation when subjected to external forces.

[0026] Wind load: refers to the external pressure generated by wind acting on the surface of an object.

[0027] Photovoltaic modules: generally referring to solar cell modules, are a number of individual solar cells sealed together in series and parallel to prevent corrosion of the cell electrodes and interconnects, prevent cell breakage, and facilitate outdoor installation.

[0028] Module cable: Steel strands used for mounting photovoltaic modules, connected between the crossbeams of the photovoltaic support structure.

[0029] Load-bearing cable: A steel strand that connects the two crossbeams and is connected to the component cable by a hinge.

[0030] Tripod: A triangular structure formed by welding or bolting profiles. The three vertices of the tripod are connected to two component cables and one load-bearing cable, respectively, forming a large-span flexible support system.

[0031] Truss: A support structure made of steel sections that connect two triangular frames. A truss can be used horizontally as a single piece or in an X-shape with two pieces crossed.

[0032] Side beams: The crossbeams at both ends of the flexible support, used to connect component cables and load-bearing cables inwards, and to connect stay cables outwards.

[0033] Stay cables: Cable structures used to connect side beams and anchor piles, typically at a 45-degree angle, but other angles are possible depending on project requirements.

[0034] Anchor piles: Located on the outside of the side beam, usually 0.2 meters above the ground, with a connecting plate on top, and connected to the side beam by inclined cables. The force of the component cable is transmitted to the anchor pile through the side beam and the inclined cables.

[0035] Land use boundary line: The red line for the planned land use area for photovoltaic construction. The construction process shall not exceed the red line land use area.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
