Description

Technical Field

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

[0002] In mountain photovoltaic projects, steep slopes, undulating terrain, and various irregular changes are often encountered. Under these complex mountain conditions, the drawbacks of traditional fixed photovoltaic support structures are becoming increasingly apparent. Due to the complexity of the terrain, traditional fixed photovoltaic support structures cannot be used for installation in many cases, reducing land use efficiency and affecting the overall photovoltaic power generation capacity.

[0003] The existing technology, CN2024118381641, describes a three-cable photovoltaic flexible support system. The existing flexible supports are mostly double-column single-layer cable structures at the end columns. This double-column form increases the number of pile foundations for the support, increases costs, and makes installation inconvenient.

[0004] The single-layer cable design results in short spans, making it unsuitable for crossing large gullies and limiting its adaptability to various terrains. Furthermore, the lack of a lower-layer cable prevents the formation of an effective mesh-like spatial structure between rows, leading to poor stability of the support system.

[0005] Therefore, a flexible photovoltaic support system for mountainous areas needs to be designed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a flexible photovoltaic support system for mountainous areas, so as to overcome the above-mentioned shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A flexible photovoltaic support system for mountainous areas includes several sets of flexible support systems arranged side by side. Each flexible support system includes end column assemblies at both ends, several sets of intermediate column assemblies between the end column assemblies, and a steel cable system passing through the end column assemblies and intermediate column assemblies. Each end column assembly includes an end column pile foundation placed on the ground of the erection area, an end column on the end column pile foundation, and an end column crossbeam perpendicular to the end column and located at the end of the end column. The steel cable system includes upper cables and lower cables. One end of the upper cable is fixed to the end column crossbeam at one end, and the other end passes through several intermediate column crossbeams in sequence and connects to the end column crossbeam at the other end. Triangular bracing structures are provided below the upper cables between the intermediate column assemblies. Adjacent rows of triangular bracing structures are connected by cross-arranged support rods to form a mesh-like spatial structure.

[0009] Preferably, column beam ear plates are provided at both ends of the end column beam; lock holes are also provided at both ends of the end column beam; the intermediate column assembly includes a middle column and a middle column beam provided at the end of the middle column, and lock holes are provided on the middle column beam.

[0010] Preferably, the end beams at both ends of the end column are fitted with stay cables via U-bolts, and the other end of the stay cables is fitted with a cable reel.

[0011] Preferably, a photovoltaic panel clamp is installed on the upper cable.

[0012] Preferably, in the flexible support system between rows, a cross support structure is provided between the end columns of two adjacent rows at the same beginning or end, and the adjacent middle column components are also connected by a cross support structure.

[0013] The beneficial effects of this utility model are: compared with the prior art, this technical solution adopts a single column structure for the end column, which reduces the number of foundations for the end column by half, while facilitating construction and improving installation efficiency.

[0014] This flexible support structure system connects the columns and triangular supports in the lateral direction using struts or cables to form a mesh-like spatial structure, making the support array a unified spatial network structure. In particular, each span of the support system features several triangular supports, separating the upper and lower cables to create a double-layer, three-cable spatial structure. Wind-resistant ropes are installed at the outermost and innermost triangular supports to reduce the upward sway of the photovoltaic panels under wind suction. The overall design reduces mid-span deflection and improves stability even with large spans, making this large-span design highly practical for mountainous environments. Attached Figure Description

[0023] Reference Figures 1 to 7 A flexible photovoltaic support system for mountainous areas includes several sets of flexible support systems 1 arranged side by side. The flexible support system includes end column assemblies 2 placed at both ends, several sets of intermediate column assemblies 3 placed between the end column assemblies at both ends, and a steel cable system 4 passing through the end column assemblies at both ends and the intermediate column assemblies.

[0024] The flexible support systems are provided with intersecting cross support structures 6;

[0025] The end column assembly 2 includes an end column pile base 21 placed on the ground of the erection area, an end column 22 set on the end column pile base 21, and an end column crossbeam 23 set perpendicular to the end column and placed at the end of the end column.

[0026] To strengthen the fixed installation of the entire end column assembly 2 and improve its stability, column beam ear plates 24 are provided at both ends of the end column beam 23; to facilitate the use with the steel cable system, lock holes are also provided at both ends of the end column beam 23.

[0027] The end beams 24 at both ends of the end column beam 23 are fitted with stay cables 25 by U-bolts, and the other end of the stay cables is fitted with a cable reel 26. The cable reel is placed on the ground in the erection area and is mainly used to bear the horizontal and vertical loads of the steel cables on the end column.

[0028] The intermediate column assembly 3 includes a central column 31 and a central column crossbeam 32 disposed at the end of the central column. In order to facilitate use with the steel cable system, a locking hole is provided on the central column crossbeam.

[0029] The cable system 4 includes an upper cable 41 and a lower cable 42. The upper cable 41 is positioned higher than the lower cable 42. One end of the upper cable 41 is fixed to the end column beam at one end (i.e., it is set to cooperate with the lock hole), and the other end passes through multiple middle column beams in sequence and connects to the end column beam at the other end. Two sets of upper cables 41 are set and arranged parallel to each other. A triangular bracing structure 5 is set below the upper cables between the middle columns. The lower cable 42 passes through the triangular bracing structure 5 between each span and the middle column beam from the middle position of the end column beam and then connects to the end column beam on the other side. A single row realizes a double-layer three-cable structure system for the support.

[0030] To enhance wind resistance and improve overall strength, wind-resistant ropes are installed on the outermost two triangular support structures 5 and the middle triangular support, and the wind-resistant ropes are fixed to the ground.

[0031] Specifically, the upper and lower cables are separated by a triangular bracing structure, forming a double-layer, three-cable spatial structure. Wind-resistant ropes are installed at the outermost and innermost triangular bracings to reduce the upward sway of the photovoltaic panels under wind suction.

[0032] Between rows, column supports are provided between the first and last row end columns. At the same time, the cross support structure 6 is placed between the two end columns. Other middle columns are connected by the cross support structure 6. For easy adjustment, the cross support structure 6 adopts a telescopic and adjustable support rod, which facilitates adjustment and is suitable for different terrains.

[0033] To further enhance the stability between the ropes, cross-connecting support rods 7 are used between adjacent rows of triangular bracing structures 5 to form a mesh-like spatial structure, thus connecting this support array into a whole spatial website structure.

[0034] A photovoltaic panel clamp 8 is installed on the upper cable to facilitate the installation and fixation of the photovoltaic panel assembly 9.

[0035] In this implementation case, multiple sets of flexible support systems 1 are planned and arranged side by side according to the size of the terrain to be installed, with spacing set, and end column components 2 are installed at both ends. Several sets of intermediate column components 3 are set between the end column components 2. After installation, inclined cables 25 are installed outward from both ends of the end column crossbeam of the end column component 2, and fixed with the cable tray 26 to fix the foundation.

[0036] Two parallel upper cables 41 are provided at both ends of the end column crossbeam 23. The middle column crossbeam 32 of several sets of intermediate column components passes through the two ends of the end column crossbeam in sequence and connects to the end column crossbeam 23 on the other side. Several sets of triangular support structures 5 are provided below the upper cables 41 between the columns. After the lower cable 42 passes through the cross-sectional triangular support structure 5 and the middle column crossbeam in sequence from the middle position of the end column main crossbeam, it is connected to the end column crossbeam 23 on the other side.

[0037] Then, the columns at the beginning or end of the same row are connected by crossbeams and cross steel wire ropes 27, and the columns in the same column are connected by cross steel wire ropes 27.

[0038] The triangular support structures between adjacent rows are connected by cross bracing rods, and the bottom is connected by crossbeam cable 28;

[0039] To further enhance wind resistance, wind-resistant ropes are installed at the triangular support structures of the flexible support system on both outermost sides and in the middle, and attached to the bottom surface.

[0040] Finally, install the photovoltaic panel clamp 8 on the upper cable 41, and fix the corresponding photovoltaic panel assembly 9 in place with the photovoltaic panel clamp 8. (Refer to...) Figure 1 The image shown is a screenshot of the result after installation.

[0041] The advantages of this utility model are that, compared with the prior art, this technical solution adopts a single-column structure for the end columns, which reduces the number of foundations for the end columns by half, while facilitating construction and improving installation efficiency.

[0042] This flexible support structure system connects the columns and triangular supports in the lateral direction using struts or cables to form a mesh-like spatial structure, making the support array a unified spatial network structure. In particular, each span of the support system features several triangular supports, separating the upper and lower cables to create a double-layer, three-cable spatial structure. Wind-resistant ropes are installed at the outermost and innermost triangular supports to reduce the upward sway of the photovoltaic panels under wind suction. The overall design reduces mid-span deflection and improves stability even with large spans, making this large-span design highly practical for mountainous environments.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
