Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support structure, and in particular to a flexible photovoltaic support wind-resistant cable-stayed structure and a spatial three-cable wind-resistant system. Background Technology

[0002] For large-span (over 35m) cable structures of photovoltaic flexible supports, in addition to the two main cables, a third stabilizing cable is required to ensure the safety of the cable structure (stability of the support under wind pressure, snow pressure, and wind vibration). This is called a three-cable system, which means that a load-bearing stabilizing cable of equal or higher strength is set below the two main cables.

[0003] The third cable is a load-bearing cable, running in the east-west direction. In order to enhance the wind resistance of the overall cable net structure, a cable structure is also needed in the north-south direction. The overall stress stability is enhanced by connecting the rows together. In the past, no north-south cable structure was set up, so the support system had poor wind and snow load resistance. Even if a north-south wind-resistant cable system was set up, it could not effectively resist loads due to unreasonable structural design. Utility Model Content

[0004] This invention provides a flexible photovoltaic support wind-resistant cable-stayed structure and a spatial three-cable wind-resistant system, which can solve the problem of poor wind and snow load resistance in existing technologies that do not have wind-resistant cable structures.

[0005] A flexible photovoltaic support wind-resistant cable-stayed structure includes:

[0006] Multiple photovoltaic support frames are used to support photovoltaic panels;

[0007] At least one wind-resistant cable is used to connect multiple photovoltaic support frames in series; and

[0008] Two foundation piles are connected to the two ends of the wind-resistant cable, respectively.

[0009] The photovoltaic support frame has a triangular structure.

[0010] The photovoltaic support frame includes three links, with the two ends of any link connected to two adjacent links respectively.

[0011] Each of the foundation piles is provided with a stay pile on its side, and the stay pile is connected to the foundation pile by at least one stay cable.

[0012] There are two wind-resistant cables, located at different heights.

[0013] One of the wind-resistant cables is connected to the connection point of the two links, and the other wind-resistant cable is connected to one of the links.

[0014] The two adjacent photovoltaic support frames are connected by two staggered support members.

[0015] Of the three connecting rods of the photovoltaic support frame, the uppermost connecting rod is inclined.

[0016] The foundation piles include a bottom pile and a movable pile hinged to the bottom pile. The inclined piles are connected to the movable piles by inclined cables, and the connection point between the inclined cables and the movable piles is higher than the connection point between the inclined cables and the inclined piles.

[0017] A spatial three-cable wind-resistant system includes at least one flexible photovoltaic support wind-resistant cable-stayed structure, and also includes a spatial three-cable structure. The spatial three-cable structure includes two main cables and a load-bearing cable located below the two main cables. The two main cables and the load-bearing cable are fixedly connected to the photovoltaic support frame, and both ends of the main cables and the load-bearing cable are connected to foundation piles.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the spatial three-cable structure composed of two main cables and a load-bearing cable, plus the design of wind-resistant cable, can interconnect the horizontal and vertical photovoltaic support components to form a whole force transmission, which enhances the overall safety and stability. Among them, the spatial three-cable structure effectively improves the load-bearing capacity of the flexible photovoltaic support system, and is more suitable for harsh weather environments than the existing ordinary photovoltaic support system.

[0027] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0028] Example 1

[0029] like Figures 1 to 3 As shown in the figure, the flexible photovoltaic support wind-resistant cable-stayed structure provided in this embodiment of the utility model is applied to a space three-cable wind-resistant system, including multiple photovoltaic support frames 1, at least one wind-resistant cable 2 and two foundation piles 3;

[0030] Among them, multiple photovoltaic support frames 1 are used to support photovoltaic panels and are arranged in a matrix;

[0031] This embodiment takes two wind-resistant cables 2 as an example. The two cables are at different heights and the ends of the wind-resistant cables 2 are fixedly connected to the foundation piles 3.

[0032] In this embodiment, the photovoltaic support frame 1 has a triangular structure. Specifically, the photovoltaic support frame 1 includes three connecting rods 4. The two ends of any connecting rod 4 are respectively connected to two adjacent connecting rods 4. The connection method can be welding, riveting, etc., and the specific fixing method is not limited. Among the three connecting rods 4 of the photovoltaic support frame 1, the uppermost connecting rod 4 can be designed to be inclined, so that the photovoltaic support frame 1 forms an inverted triangle shape. This design can effectively unload force and overcome the swaying caused by wind vibration.

[0033] The connection points between the two wind-resistant cables 2 and the photovoltaic support frame 1 are not restricted. In addition, the connection method can be fixed by existing steel cable fasteners. The connection positions in this embodiment are as follows: one of the two wind-resistant cables 2 is connected to the connection point of the two connecting rods 4, and the other wind-resistant cable 2 is connected to one of the connecting rods 4.

[0034] In addition, a tie pile 6 is provided on the side of each foundation pile 3. The tie pile 6 is connected to the foundation pile 3 by at least one tie cable 5, which can effectively prevent the pile from undergoing horizontal displacement due to excessive horizontal force on a single pile.

[0035] In some other embodiments, the foundation pile 3 is designed as a rocking structure. Specifically, the foundation pile 3 includes a bottom pile 7 and a movable pile 8 hinged to the bottom pile 7. The inclined pile 6 is connected to the movable pile 8 by an inclined cable 5. The connection point between the inclined cable 5 and the movable pile 8 is higher than the connection point between the inclined cable 5 and the inclined pile 6.

[0036] Example 2

[0037] like Figure 4As shown, based on Embodiment 1, this embodiment proposes a flexible photovoltaic support wind-resistant inclined structure. The difference from Embodiment 1 is that in this embodiment, two adjacent photovoltaic support frames 1 are connected by two staggered support members 9, and the two photovoltaic support frames 1 located on the outermost side are connected to the foundation piles 3 by wind-resistant cables 2. This design also effectively improves the overall stability of the flexible photovoltaic support.

[0038] Example 3

[0039] like Figures 5-6 As shown, this embodiment proposes a spatial three-cable wind-resistant system, which also includes at least one flexible photovoltaic support wind-resistant cable-stayed structure, and spatial three-cable structures corresponding one-to-one with multiple photovoltaic support frames 1.

[0040] The flexible photovoltaic support wind-resistant cable-stayed structure in this embodiment is multiple, and includes the two forms of Embodiment 1 and Embodiment 2 above, and the two are arranged alternately.

[0041] The spatial three-cable structure of this embodiment includes two main cables 13 and a load-bearing cable 10 located below the two main cables 13. Both the two main cables 13 and the load-bearing cable 10 are fixedly connected to the photovoltaic support frame 1. The fixed connection can be achieved by welding, fixing with cable hoops, binding with steel wire ropes, etc., and the specific method is not limited. In addition, the specific connection point is not limited. In this embodiment, the load-bearing cable 10 is connected to the lowest point of the photovoltaic support frame 1. Both ends of the main cables 13 and the load-bearing cable 10 are connected to the foundation piles 3.

[0042] In addition, the spatial three-cable structure is fixedly installed on the load-bearing component 11, and a foundation base 12 is provided on the lower side of the load-bearing component 11. The foundation pile 3 is connected to the load-bearing component 11 through the stay cable 5.

[0043] The spatial three-cable structure composed of two main cables 13 and a load-bearing cable 10, along with the design of the wind-resistant cable 2, can interconnect the horizontal and vertical photovoltaic support components 9 to form a whole force transmission system, enhancing the overall safety and stability. The spatial three-cable structure effectively improves the load-bearing capacity of the flexible photovoltaic support system, making it more suitable for harsh weather environments than existing ordinary photovoltaic support systems.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
