Technical Field

[0001] This utility model relates to the field of building and new energy technology, specifically to a novel roof photovoltaic support system. Background Technology

[0002] With the rapid development of renewable energy, photovoltaic (PV) power generation systems are increasingly being used in buildings. As a key clean energy source that directly converts sunlight into electricity, PV technology has enormous development potential. Countries around the world are actively promoting the research and development of PV technology to improve its conversion efficiency, stability, and economic viability, thereby driving the optimization and transformation of the energy structure.

[0003] Currently, there are various rigid support schemes for rooftop photovoltaic (PV) systems, including: precast cement schemes for new roofs, load-bearing retrofit schemes for existing building roofs, flat-lay clamp schemes for light steel factory roofs, and non-precast roof guide plate bracket schemes. However, traditional schemes have the following main problems: (1) Installing PV modules by reinforcing or modifying the roof structure is not only costly but also complex to construct, and may affect the building's functionality; (2) For large buildings, especially those designed as non-accessible roofs, adding a PV support system will significantly increase the roof load, which may cause structural safety hazards. Therefore, there is an urgent need for an efficient, economical, and safe rooftop PV load transfer solution. Utility Model Content

The system effectively avoids additional loads on the roof structure by anchoring the cable structure to the ground concrete foundation. Furthermore, it connects to the building structure via cable supports and employs a rational cross-sectional design to enhance overall stability.

[0005] The technical solution provided by this utility model is: a novel roof photovoltaic support system, including a load-bearing cable, an anchor cable, a cable support and connectors, and anchors; wherein, the cable support is connected to the longitudinal beam of the building structure through a support base, ensuring its rotatability; the load-bearing cable is connected to the cable supports on both sides; one end of the anchor cable is connected to the cable support, and the other end is connected to the ground concrete foundation through an anchoring device and an anchoring collar; the cable support forms an angle of 30-60 degrees with the horizontal plane.

[0006] Preferably, a height difference is set between two adjacent sets of catenary cables to install photovoltaic modules with different tilt angles.

[0007] Preferably, the cable support includes a support cantilever and a support ear plate; the support ear plate is disposed at both ends of the support cantilever, and a support pull hole is reserved on the support ear plate; the support cantilever adopts an unequal cross-section design, and its surface is provided with reinforcing ribs.

[0008] Preferably, the support base includes a support base bottom plate, a support base clamping plate, and high-strength bolts; the support base bottom plate is connected to the longitudinal beam, and the cable support is placed in the middle of the support base clamping plate and fixed by high-strength bolts.

[0009] Preferably, the anchoring device includes an anchoring base plate and an anchoring clamp; the anchoring base plate is connected to the ground foundation, and the anchoring clamp is fixed on the anchoring base plate; the lower end of the anchoring cable is hinged to the anchoring base plate.

[0010] The advantages of this utility model are:

[0024] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate a preferred embodiment of this utility model. However, this utility model is not limited to the described embodiment and can actually be implemented in many different forms. The purpose of providing these embodiments is to enable those skilled in the art to more comprehensively and deeply understand the technical content of this utility model.

[0025] This embodiment uses a building structure with a span of 20m, a height of 8m, and a longitudinal length of 72m as an example, and a flexible photovoltaic support system with a height of approximately 2m is constructed on its roof. Figure 1 and Figure 2 As shown, building structure 1 includes steel frame columns 11, steel frame beams 12, longitudinal beams 13, wind-resistant columns 14, and wall beams 15. The flexible photovoltaic support system mainly consists of load-bearing cables 21, anchor cables 22, cable supports 23, and several connectors and anchors.

[0026] like Figure 1 and Figure 2 As shown, the flexible cable support system 2 is arranged along the span direction of the building structure 1, while the photovoltaic modules 3 are arranged along the longitudinal direction of the building structure 1. The catenary 21 supports the photovoltaic modules 3, and the cable support 23 is connected to the catenary 21 and further anchored by the anchor cable 22. The cable support 23 is connected to the longitudinal beam 13, transferring the load to the steel frame column 11.

[0027] like Figure 3 As shown, the cable supports 23 can be arranged at different tilt angles as needed and are equipped with load-bearing cables 21 of different lengths, thereby forming a height difference between adjacent load-bearing cables, and thus realizing the arrangement of photovoltaic modules 3 with fixed tilt angles. Each cable support 23 is also anchored to the ground foundation by a vertical anchor cable 22.

[0028] like Figure 4As shown, the cable support 23 is connected to the longitudinal beam 13 of the building structure through the support base 24; the horizontal load-bearing cable 21 is connected to the cable support 23 through the load-bearing cable end plate 25; and the vertical anchor cable 22 is connected to the cable support 23 through the anchor cable end plate 26.

[0029] like Figure 4 and Figure 5 As shown, the cable support 23 includes a support cantilever 231, support lugs 232, support tension holes 233, and stiffening ribs 234. The support cantilever 231 adopts an unequal cross-section design to resist the bending moment caused by the catenary cable 21 and the anchor cable 22; the support lugs 232 at both ends are used to connect the anchor cable 22 and the longitudinal beam 13 of the building structure 1, respectively; the support tension hole 233 is located in the middle of the cable support 23 and is used to connect with the catenary cable 21. In addition, by reserving holes of different heights, the installation requirements of different types and tilt angles of photovoltaic modules 3 can be met; stiffening ribs 234 are welded to the edges of the cable support 23 and at the support tension holes 233 to improve the out-of-plane stiffness of the cable support 23 and resist the cross-sectional bending moment in the cable support 23.

[0030] like Figure 6 As shown, the support base 24 includes a support base bottom plate 241, a support base clamping plate 242, and high-strength bolts 243. The support base bottom plate 241 is connected to the longitudinal beam 13, and the cable support 23 is placed in the middle of the support base clamping plate 242 and fixed by the high-strength bolts 243.

[0031] like Figure 7 As shown, the anchoring device 27 consists of an anchoring base plate 271, an anchoring clamp plate 272, and a central round rod 273. The anchoring base plate 271 is connected to the ground foundation, and the anchoring cable 22 passes around the central round rod 273 and is fixed by the anchoring collar 28 to prevent the anchoring cable 22 from loosening or slipping.
