Description

Technical Field

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

[0002] Flexible mounting systems have far surpassed traditional fixed mounting systems in terms of terrain adaptability; however, common flexible mounting systems are usually deployed in locations with gentle slopes, such as hills. As the installed capacity of photovoltaic systems increases, the number of suitable terrains for their use is decreasing.

[0003] There are generally two ways to arrange flexible supports on slopes: one is to arrange them parallel to contour lines, and the other is to arrange them perpendicular to contour lines. In existing structures on steep terrain, the vertical contour line arrangement, which involves pulling steel cables from the top of the mountain to the bottom, will result in inconsistent tension at the top and bottom of the steel cables due to gravity. This means that the internal force of the same steel cable is much greater at the top of the mountain than at the bottom, making it difficult to effectively control the deflection of the flexible support. Secondly, with this arrangement, the photovoltaic panels need to be arranged along the steel cables, and the photovoltaic panel's power generation angle is consistent with the slope of the mountain. This will result in the photovoltaic panels not being at the optimal power generation angle, leading to low power generation efficiency. refer to Figure 1 The diagram shows the structural design of existing flexible support columns. In this common design, the columns are typically installed vertically downwards. In this method, the distance from the top of the column to the slope is related to the slope angle. If the slope at the column is A and the column height is L, then the distance from the top of the column to the slope is D = L * cosA. It can be seen that with a fixed column height L, D decreases as the slope A increases. That is, the steeper the slope, the smaller the distance from the top of the column to the slope, resulting in insufficient space for installing photovoltaic panels. This vertically downward installation method is unsuitable for terrain with steep slopes.

[0004] Therefore, a flexible support system suitable for steep slopes needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flexible support system suitable for steep slopes, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flexible support system suitable for steep slopes includes a column system, a cable-stayed system for fixing the two end column systems, a load-bearing cable system connecting the various column systems, a wind-resistant system, and photovoltaic panel mounting components installed on the load-bearing cable system, characterized in that: The column system consists of an upper column, a lower column, and a column beam. The upper and lower columns are hinged together by a row of holes and through bolts, and form a triangular structure through the column beam. The cable-stayed system includes cable stays, U-shaped adjusting bolts, and cable stay bases. The two ends of the cable stays are connected to the ear plates on the column beam and the cable stay bases, respectively. The load-bearing cable system includes two parallel steel cables. The steel cables pass through several middle column beams in sequence from the side column beams and are connected to the side column beams on the other side, and are tensioned and fixed by steel cable anchors.

[0007] Preferably, the wind-resistant system includes a wind-resistant beam, a wind-resistant rope, and a wind-resistant ground anchor. The wind-resistant beam is set between adjacent columns and connected by steel cables. One end of the wind-resistant rope is connected to the wind-resistant beam, and the other end is fixed to the wind-resistant ground anchor.

[0008] Preferably, the wind-resistant rope in the wind-resistant system is fixed between the wind-resistant beam and the wind-resistant ground anchor by rope clamps.

[0009] Preferably, the photovoltaic panel mounting assembly includes a fixing clamp and a photovoltaic panel. The photovoltaic panel is mounted on an upper steel cable via the fixing clamp. The relative position between the fixing clamp and the upper steel cable in the photovoltaic panel mounting assembly is adjustable, thereby changing the installation angle of the photovoltaic panel.

[0010] Preferably, the column beams are arranged parallel to the mounting surface, and each row is arranged independently along the contour line direction.

[0011] Preferably, the steel cables in the load-bearing cable system are tensioned and fixed on the column beam by steel cable anchors.

[0012] Preferably, the connection between the inclined base and the mounting surface is a fixed connection, and the inclined base is arranged perpendicular to the mounting surface and facing downwards.

[0013] The beneficial effects of this utility model are: the A-shaped column structure design of this technical solution ensures that the distance between the column beam and the slope is not affected by the slope change, thus ensuring that there is enough space between the photovoltaic panel installation plane and the slope. The A-shaped column structure, through the triangular design formed by the upper and lower columns and the column beam, significantly improves the column's adaptability to terrain and installation flexibility. The A-shaped structure has good triangular stability, and the vertical slope of the foundation facing downwards allows for better anchoring in the ground, thereby enhancing the overall structural stability.

[0014] The supports are arranged along the contour lines and each row of supports is set up independently, without the need for connection between adjacent supports, which greatly improves the adaptability to complex terrain.

[0015] Compared with the prior art, this utility model, through the design of a triangular A-shaped column structure, adopts an upper and lower column plus crossbeam method, which can ensure that the distance D between the column crossbeam and the slope is not affected by the change of slope A, thus ensuring that the photovoltaic panel installation plane has sufficient distance from the slope.

[0017] Reference Figures 1 to 8 A flexible support system suitable for steep slopes includes a column system 100, a cable-stayed system 200, a load-bearing cable system 300, a wind-resistant system 400, and a photovoltaic panel mounting assembly 500. The column system consists of an upper column 1, a lower column 2 and a column beam 3. The upper and lower columns are hinged to each other by column holes 20 and through bolts 13, and form a triangular structure through the column beam 3. The cable-stayed system includes a cable-stayed cable 4, a U-shaped adjusting bolt 5, and a cable-stayed base 21. The two ends of the cable-stayed cable 4 are respectively connected to the ear plate 15 on the column beam 3 and the cable-stayed base 21. The load-bearing cable system includes two parallel steel cables 6. The steel cables 6 pass through several middle column beams in sequence from the side column beams and are connected to the side column beams on the other side, and are tensioned and fixed by steel cable anchors 7. The wind-resistant system includes a wind-resistant beam 8, a wind-resistant rope 9, and a wind-resistant ground anchor 10. The wind-resistant beam 8 is set between adjacent columns, and one end of the wind-resistant rope 9 is connected to the wind-resistant beam 8, while the other end is fixed to the wind-resistant ground anchor 10. The photovoltaic panel mounting assembly includes a fixing clamp 12 and an upper steel cable 6, and the photovoltaic panel 11 is mounted on the upper steel cable 6 by the fixing clamp 12.

[0018] The column system adopts an A-shaped design, consisting of an upper column 1, a lower column 2, and a column beam 3. The upper and lower columns are hinged together by column holes 20 and through bolts 13, forming a stable triangular structure. The column beam 3 is arranged approximately parallel to the slope 25, ensuring that the distance between the column beam 3 and the slope is not affected by changes in slope, thus providing sufficient space for the installation of the photovoltaic panels 11. Each row of supports (i.e., the column system) is arranged independently along the contour line, and there is no need for direct connection between adjacent supports, significantly improving adaptability to complex terrain. To accommodate different angles, the upper column 1 and lower column 2 are each equipped with several sets of crossbeam openings 19 for installation with the column beam 3.

[0019] The installation process of the column system is as follows: First, the location of the column foundation is determined according to the actual terrain of the slope 25, and the column base 14 is fixed on the foundation. The upper and lower columns 1 and 2 are adjusted in height through the holes 20. During adjustment, the upper and lower columns are connected and fixed to the column beam 3 using through bolts 13. This design prevents the base 14 from being subjected to bending moment, reduces the requirement for the bending strength of the column, effectively reduces the weight of the column, and saves material costs. The column beam 3 has holes at both ends for steel cables to pass through, for the subsequent installation of the load-bearing cable system. In addition, ear plates 15 are provided on the outer side of the end column beam for connecting the stay cables 4.

[0020] The stay cables 4 of the cable-stayed system are located at the ends of the end column crossbeams 3, totaling two cables. One end is connected to the ear plate 15 via a U-shaped adjusting bolt 5, and the other end is fixed to the cable-stayed base 21. The design of the U-shaped adjusting bolt 5 allows the length of the stay cable 4 to be adjusted by rotating the nut, thereby adapting to the installation requirements under different terrain conditions and enhancing the flexibility and stability of the system. The stay cables 4 are mainly used to bear the horizontal and vertical loads of the steel cables 6 on the end column, while also playing a role in stabilizing the overall structure. To ensure overall strength, the cable-stayed base is connected to the column foundation that extends into the slope.

[0021] The steel cables 6 of the load-bearing cable system pass sequentially through the corresponding holes in the side column crossbeams 3, through several middle column crossbeams, and then connect to the side column crossbeams on the other side. The steel cables 6 are tensioned and fixed to the end column crossbeams by steel cable anchors 7, ensuring the stability and load-bearing capacity of the entire system. The parallel arrangement of the steel cables 6 avoids inconsistent deflection caused by changes in terrain slope, thus making the installation angle of the photovoltaic panels 11 more uniform. The tension of the steel cables 6 can be finely adjusted by the steel cable anchors 7, further ensuring the reliability of the system.

[0022] The wind-resistant beams 8 of the wind-resistant system are installed between adjacent column systems. The specific number depends on the actual installation area. One end of the wind-resistant rope 9 is connected to the wind-resistant beam 8, and the other end is fixed to the wind-resistant anchor 10. The wind-resistant rope 9 is designed to enhance the wind resistance of the support structure and reduce the impact of severe weather on the system. The arrangement of the wind-resistant system can effectively distribute wind loads and improve the stability of the overall structure. The wind-resistant anchor 10 uses either rock anchors or cast-in-place piles as the foundation, depending on the actual terrain. Rock anchors are suitable for hard rock foundations, while cast-in-place piles are suitable for soft soil foundations. The wind-resistant anchor 10 is installed vertically downwards from the slope, which allows it to be better anchored in the foundation, thereby enhancing the overall stability of the system. The wind-resistant beams are connected in conjunction with steel cables 6.

[0023] The photovoltaic panel 11 of the photovoltaic panel mounting assembly is mounted on the upper steel cable 6 via a fixing clamp 12. The relative position between the fixing clamp 12 and the steel cable 6 is adjustable, thereby changing the installation angle of the photovoltaic panel 11. This design ensures that the photovoltaic panel 11 is always at the optimal power generation angle, significantly improving power generation efficiency. The adjustment range of the installation angle of the photovoltaic panel 11 is limited by the fitting accuracy between the fixing clamp 12 and the steel cable 6, but even under conditions of large slope, it can achieve superior power generation performance.

[0024] The operating principle of this flexible support system in practical applications is as follows: When the photovoltaic support is installed on a steep slope, the A-shaped column structure can effectively cope with changes in terrain slope. The upper and lower columns 1 and 2 are adjusted in height through the holes 20 to ensure that the column beam 3 remains parallel to the slope surface 25. The steel cable holes on the column beam 3 are used to install the load-bearing cable system. The arrangement of the steel cables 6 solves the problem of inconsistent deflection in traditional flexible supports on steep terrain. The length of the stay cables 4 is adjusted through U-shaped adjusting bolts 5, enabling the system to maintain stability under different terrain conditions. The wind-resistant system enhances the overall structure's wind resistance through the synergistic effect of the wind-resistant beam 8, wind-resistant rope 9, and wind-resistant ground anchor 10. The photovoltaic panels 11 are installed on the steel cables 6 through fixing clamps 12, and their angle can be flexibly adjusted according to the terrain slope to ensure maximum power generation efficiency.

[0025] The construction process of the flexible support system in complex terrain according to this embodiment is as follows: First, the location of the column foundation is determined based on the on-site survey results, and rock anchors or cast-in-place piles are selected as the foundation scheme according to the terrain. Then, the column system is installed, and the heights of the upper and lower columns 1 and 2 are adjusted to ensure that the column crossbeams 3 are parallel to the slope 25. After completing the column system, the cable-stayed system is installed, and the length of the cable-stayed cables 4 is adjusted to adapt to the actual terrain conditions. Next, the load-bearing cable system is installed, and the steel cables 6 are passed through each column crossbeam 3 in sequence and tensioned and fixed on the end column crossbeams. Finally, the wind-resistant system and photovoltaic panels 11 are installed to ensure the stability of the overall structure and the power generation efficiency.

[0026] The advantages of this utility model are that the A-shaped column structure of this technical solution, through the triangular design formed by the upper and lower columns and the column beam, significantly improves the terrain adaptability and installation flexibility of the column.

[0027] The column system is arranged along the contour lines and each row of supports is set up independently, without the need for connection between adjacent rows, which greatly improves the adaptability to complex terrain.

[0028] The height-adjustable installation design is achieved through the holes 20 on the upper and lower columns and the column beams, which facilitates the adjustment of the column installation according to the terrain and ensures the consistency of the photovoltaic panel installation angle.

[0029] The cable-stayed system features an adjustable length design using U-shaped adjusting bolts to adapt to installation requirements under different terrain conditions.

[0030] The wind-resistant system significantly enhances the wind resistance of the support structure through the synergistic effect of wind-resistant beams, wind-resistant ropes, and wind-resistant ground anchors.

[0031] Compared with the prior art, this utility model, through the design of a triangular A-shaped column structure, adopts an upper and lower column plus crossbeam method, which can ensure that the distance D between the column crossbeam and the slope is not affected by the change of slope A, thus ensuring that the photovoltaic panel installation plane has sufficient distance from the slope.

[0032] 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.
