Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a column structure for flexible photovoltaic supports and a flexible photovoltaic support. Background Technology

[0002] With the increasing global demand for renewable energy, photovoltaic (PV) power generation, as a major force in clean energy, is seeing its application scale continuously expand. Against the backdrop of increasingly scarce land resources, complex terrain, especially rugged mountainous areas, has become a key focus for PV project construction. Compared to traditional fixed supports, flexible PV supports offer significant advantages such as large span, strong adaptability, lower steel consumption, and fewer foundations, demonstrating enormous application potential in irregular sites such as mountains, hills, and ponds.

[0003] However, when flexible photovoltaic (PV) supports are applied to complex mountainous terrain with steep slopes and significant elevation differences, their inherent structural characteristics present new technical challenges. Flexible supports typically form a stable cable-net structure using prestressed cables, with PV modules laid on top and load-bearing cables tensioned below. This structure will experience some sagging displacement when subjected to wind loads, snow loads, and its own weight. In mountainous environments, due to the undulating terrain, flexible PV supports are highly susceptible to collisions or interference with protruding slopes at mid-span.

[0004] Such collision issues can trigger a series of serious engineering risks and safety hazards, including component damage, structural friction with the mountain, corrosion layer peeling off, electrical wiring short circuits, and many other risks, directly affecting the safe and stable operation of photovoltaic power stations.

[0005] Traditional solutions typically involve increasing the height of the side columns to improve the clearance between the support structure and the slope. However, this leads to a significant increase in material costs, raises the structural center of gravity, reduces wind resistance, and in some steep terrains, simply increasing the height of the columns may not be an effective solution. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the first objective of this invention is to provide a column structure for flexible photovoltaic (PV) mounting systems. When installed on a flexible PV mounting system, this invention enables the system to adapt to the undulating terrain of mountainous areas and traverse protruding mountainsides, thereby ensuring that the flexible PV system does not collide with or damage the mountainous terrain.

[0007] In a first aspect, the present invention provides a column structure for a flexible photovoltaic support, comprising a front column, a rear column, a pile cap structure, and a support structure. The front column and the rear column are supported on a complex mountain foundation with a large slope or significant elevation difference. The pile cap structure is rotatably mounted on the top of both the front column and the rear column. The two ends of the support structure are respectively connected to the front column and the rear column through corresponding pile cap structures. The pile cap structure is provided with a first connecting part and a second connecting part. The first connecting part and the second connecting part have a linked adjustable position state as the pile cap structure rotates. The first connecting part is connected to the support structure.

[0008] As a preferred embodiment of the present invention: the support structure includes an upper connecting component and a lower connecting component connected to each other; the two ends of the upper connecting component are rotatably connected to the corresponding first connecting part, and the two ends of the lower connecting component are rotatably connected to the column body of the front column or the rear column.

[0009] As a preferred technical solution of the present invention: the pile cap structure includes a sleeve, a first connecting part, a second connecting part, and an arc-shaped cover plate. The sleeve is rotatably fitted onto the top of the front column or the rear column. The first connecting part and the second connecting part are symmetrically arranged on the outer side wall of the sleeve. The arc-shaped cover plate is disposed on the top of the sleeve. A component cable mounting structure is provided on the arc-shaped cover plate and is connected to the component cable of the flexible photovoltaic bracket through the component cable mounting structure.

[0010] As a preferred embodiment of the present invention: the first connecting part and the second connecting part are respectively disposed on both sides of the upper part of the sleeve, and a locking structure is provided at the lower part of the sleeve.

[0011] As a preferred technical solution of the present invention: the arc-shaped cover plate includes a base and arc-shaped guide sections disposed on both sides of the base and bent downward, the bending surface of the arc-shaped guide sections being arranged in the same direction as the first connecting part and the second connecting part.

[0012] As a preferred technical solution of the present invention: small clamps are fitted on the column bodies of the front column and the rear column, and wind-resistant cable installation structures are provided on the small clamps, and the wind-resistant cable installation structures are connected to the wind-resistant cables of the flexible photovoltaic support.

[0013] As a preferred technical solution of the present invention: a load-bearing cable installation structure is provided on the upper connecting component, and the load-bearing cable installation structure is connected to the load-bearing cable of the flexible photovoltaic bracket.

[0014] Secondly, a second objective of the present invention is to provide a flexible photovoltaic support structure, comprising a base support structure, a strut structure, ropes, and a column structure as described in any of the preceding claims. The base support structure is supported on a mountain foundation, the ropes are connected to the base support structure, and the strut structure is supported on the ropes. The two sides of the column structure are used to connect to the strut structure, and the front column, rear column, pile cap structure, and support structure are connectable to the ropes on the flexible photovoltaic support structure.

[0015] The beneficial effects provided by this invention are as follows:

[0016] 1. When installed on a flexible photovoltaic support, this invention allows the flexible photovoltaic support to adapt to the undulating terrain of mountainous areas and cross protruding mountains, thereby ensuring that the flexible photovoltaic support does not collide with or be damaged by the mountainous terrain.

[0017] 2. This invention improves construction tolerance and installation efficiency by employing a sleeve-type pile cap structure as a "connection converter," separating the high-precision column positioning requirements from the pile top alignment requirements. This design allows the connection position to be finalized after the column is installed by rotating and adjusting the pile cap structure, significantly reducing the installation accuracy requirements for the column in terms of planar angle and elevation, thereby simplifying the installation process and improving on-site construction efficiency and tolerance.

[0018] 3. This invention enhances structural durability and safety by incorporating an arc-shaped guide section on the arc-shaped cover plate, achieving a smooth transition between the steel cable and the fixing plate. This design effectively avoids stress concentration and frictional damage at the connection points of the steel cable, improving the fatigue life of the steel cable and the safety and reliability of the entire support system during long-term operation.

[0019] 4. This invention significantly shortens the project construction cycle by adopting a scheme where the columns are separated from the upper connection nodes and installed independently. After the columns are procured to the required dimensions, they can be directly poured. During the "equal strength gap" period for the curing of the foundation grout, the processing and transportation of other node components can be carried out simultaneously. This parallel operation mode makes reasonable use of time and greatly shortens the overall construction period of the project. Attached Figure Description

Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present invention.

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0046] like Figure 7As shown, a column structure for a flexible photovoltaic support includes a front column 1602, a rear column 1601, a pile cap structure 17, and a support structure. The front column 1602 and the rear column 1601 are supported on a complex mountain foundation 15 with a large slope or significant elevation difference. The pile cap structure 17 is rotatably mounted on the top of both the front column 1602 and the rear column 1601. The two ends of the support structure are respectively connected to the front column 1602 and the rear column 1601 through corresponding pile cap structures 17. The pile cap structure 17 is provided with a first connecting part 1702 and a second connecting part 1703. The first connecting part 1702 and the second connecting part 1703 have a linked adjustable position state as the pile cap structure 17 rotates, so as to eliminate the relative posture error caused by the front column 1602 and the rear column 1601 on the steep mountain foundation 15. The first connecting part 1702 is connected to the end of the support structure, and the second connecting part 1703 can cooperate with the strut structure of the flexible photovoltaic bracket.

[0047] Specifically, boreholes are drilled on the mountain foundation 15, and the front column 1602 and the rear column 1601 are vertically placed into the boreholes. The depth of the front column 1602 and the rear column 1601 is adjusted to ensure that the top height of the front column 1602 and the rear column 1601 reaches the design elevation. Then, grouting material 26 is poured into the boreholes.

[0048] The support structure includes an upper connecting component and a lower connecting component connected to each other; the two ends of the upper connecting component are rotatably connected to the corresponding first connecting part 1702, and the two ends of the lower connecting component are rotatably connected to the column body of the front column 1602 or the rear column 1601.

[0049] like Figures 15-20 As shown, specifically, the upper connecting part is a crossbeam 23, with both ends hinged to the corresponding first connecting part 1702; the lower connecting part includes a rear diagonal brace 21 and a front diagonal brace 22, one end of the front diagonal brace 22 and the rear diagonal brace 21 being connected to the middle of the crossbeam 23, and the other end being rotatably connected to the column body of the front column 1602 or the rear column 1601 respectively; one end of the front diagonal brace 22 and the rear diagonal brace 21 is hinged to the crossbeam 23, and a large clamp 19 is fitted on the column body of the front column 1602 or the rear column 1601, with the other end of the front diagonal brace 22 and the rear diagonal brace 21 hinged to the corresponding large clamp 19. The front diagonal brace 22 and the rear diagonal brace 21 can be either round rods or rectangular tubes.

[0050] like Figures 8-14As shown, the pile cap structure 17 includes a sleeve 1704, a first connecting part 1702, a second connecting part 1703, and an arc-shaped cover plate 1701. The sleeve 1704 is rotatably fitted onto the top of the front column 1602 or the rear column 1601. The first connecting part 1702 and the second connecting part 1703 are symmetrically arranged on the outer side wall of the sleeve 1704. The arc-shaped cover plate 1701 is disposed on the top of the sleeve 1704. A component cable mounting structure is provided on the arc-shaped cover plate 1701, and it is connected to the component cable 7 of the flexible photovoltaic bracket through the component cable mounting structure.

[0051] Specifically, component cable 7 is laid flat on top of the curved cover plate 1701 and fixed by component cable wire rope clamp 1801.

[0052] The first connecting part 1702 and the second connecting part 1703 are respectively provided on both sides of the upper part of the sleeve 1704, and a locking structure is provided at the lower part of the sleeve 1704. Specifically, the first connecting part 1702 and the second connecting part 1703 are respectively provided as ear plates, and the ear plates of the pile cap structure 17 on the front column 1602 and the rear column 1601 are in the same vertical plane, thereby ensuring that the crossbeam 23 can be connected.

[0053] The inner diameter of the sleeve 1704 is larger than the outer diameter of the column, with a 4-6 mm gap reserved. The lower part of the sleeve 1704 has symmetrically opened U-shaped cutouts 1705. The outer wall of the sleeve 1704 is provided with bolt connection structures 1706 at the location of each U-shaped cutout 1705. The U-shaped cutouts 1705 are configured to provide clearance deformation space when the bolt connection structure 1706 applies a locking force, so that the lower part of the sleeve 1704 can hug and fit tightly against the outer peripheral surface of the top of the column.

[0054] The arc-shaped cover plate 1701 includes a base and arc-shaped guide sections 1707 with a certain radius of curvature located on both sides of the base and bent downwards. The bending surface of the arc-shaped guide section 1707 is arranged in the same direction as the first connecting part 1702 and the second connecting part 1703.

[0055] Small clamps 20 are fitted on the column bodies of the front column 1602 and the rear column 1601. The small clamps 20 are located below the large clamps 19. The small clamps 20 are provided with wind-resistant cable installation structures and are connected to the wind-resistant cables 5 of the flexible photovoltaic support through the wind-resistant cable installation structures.

[0056] like Figure 21 and Figure 22As shown, in this embodiment, the small clamp 20 includes two clamp plates 2001 that are connected to each other. One of the clamp plates 2001 has an integrally formed or fixedly connected multi-section steel plate 2003 extending outward on its outer side wall. The wind-resistant cable installation structure includes a wind-resistant cable wire rope clamp 25 and an installation plate 2004. The wind-resistant cable 5 is laid flat on the installation plate 2004 and fixed by the wind-resistant cable wire rope clamp 25.

[0057] The upper connecting component is provided with a load-bearing cable installation structure, and is connected to the load-bearing cable 6 of the flexible photovoltaic support through the load-bearing cable installation structure.

[0058] The load-bearing cable installation structure includes a top cover plate 2304 and a load-bearing cable wire rope clamp 1802. The top cover plate 2304 is fixed to the crossbeam 23, and the load-bearing cable 6 is fixed to the top cover plate 2304 through the load-bearing cable wire rope clamp 1802.

[0059] The column structure of this invention enables rapid assembly construction and improves the safety of mountain operations. All major connection nodes can be connected using high-strength bolts, achieving rapid assembly and simplifying the construction process. Simultaneously, this method completely avoids on-site welding operations, making it particularly suitable for environmentally sensitive areas such as mountains and hills. It fundamentally eliminates the risk of wildfires caused by welding, ensuring safety during construction and operation.

[0060] like Figures 1-2 As shown, this embodiment of the invention also provides a flexible photovoltaic support structure, specifically a flexible photovoltaic support structure with a double-layer three-cable wind-resistant system, including a basic support structure, a strut structure, ropes, and a column structure 14 as described above. The basic support structure is supported on a mountain foundation 15, the ropes are connected to the basic support structure, the strut structure is supported on the ropes, and the top of the strut structure is used to install photovoltaic modules 3. The two sides of the column structure 14 are used to connect to the strut structure, and the front column 1602, the rear column 1601, the pile cap structure 17, and the support structure can be connected to the ropes on the flexible photovoltaic support structure.

[0061] In this embodiment, the basic support structure includes a support system composed of multiple side anchor foundations 1, multiple side supports 2, and multiple wind-resistant foundations 4. The ropes include a rope system composed of multiple wind-resistant cables 5, multiple load-bearing cables 6, multiple component cables 7, and multiple stay cables 10. The strut structure includes multiple component struts 12 and multiple row struts 13.

[0062] The load-bearing cable 6 is connected between the two side supports 2, the wind-resistant cable 5 is connected between the two wind-resistant foundations 4, and multiple component struts 12 and multiple row struts 13 are arranged alternately, with their bottoms fixed to the wind-resistant cable 5 and the load-bearing cable 6. The upper parts of the multiple component struts 12 and multiple row struts 13 are connected to the component cable 7.

[0063] like Figures 3-4 The diagram shows a cross-section of the wind-resistant system of the flexible photovoltaic (PV) support array along the north-south direction. The mountainous terrain is complex and varied, with undulating terrain. The component support rod 12 of the flexible PV support collides with the mountain foundation 15 at the E-axis. Therefore, at the point where the component support rod 12 collides with the mountain foundation 15 at the E-axis, the component support rod 12 is removed, and a column structure 14 is installed to raise the wind-resistant system of the flexible PV support, extending it beyond the protruding mountain foundation 15.

[0064] like Figures 5-6 As shown, a cross-section of the load-bearing system of the flexible photovoltaic support array along the east-west direction is displayed. The mountain terrain is complex and varied, with undulating terrain. The wind-resistant triangular brace 11 of the flexible photovoltaic support's load-bearing cable 6 collides with the mountain foundation 15. Therefore, as... Figure 6 As shown, at the point where the wind-resistant triangular brace 11 of the flexible photovoltaic support cable 6 collides with the mountain foundation 15, the component support rod 12 at that point is removed, the overall column structure 14 is installed, the wind-resistant system of the flexible photovoltaic support is raised, and it passes over the protruding mountain 15.

[0065] This invention provides a method for installing a column structure, specifically including the following steps:

[0066] S1: Conduct a profile analysis of the project terrain to identify areas where the flexible photovoltaic support will collide with the mountain. Select these areas to add an overall column structure 14.

[0067] S2: Drill holes, insert columns, adjust the top height of the front column 1602 and the rear column 1601 to the design elevation, ensure that the height difference angle between the two columns is the design tilt angle of the photovoltaic module 3, and after adjusting the verticality of the columns, pour the grout 26 into the drilled holes.

[0068] S3: During the grouting process of grouting material 26, complete the processing and transportation of other node components to the construction site.

[0069] S4: Insert the pile cap structure 17 onto the top of the front column 1602 and the rear column 1601. Position the ear plates of the two pile cap structures 17 in the same vertical plane. Securely attach the pile cap structure 17 to the corresponding column through the locking structure.

[0070] S5: Align the ear plates at both ends of the crossbeam with the ear plates of the pile cap structure 17 on the front column 1602 and the rear column 1601 respectively. At this time, the top cover plate 2304 on the crossbeam is on top. Then, pass the bolts through the ear plates at the ends of the crossbeam and the ear plates of the pile cap structure 17, tighten the bolt group, and realize the connection between the crossbeam and the pile cap structure 17.

[0071] S6: Connect large clamps 19 to the front pillar 1602 and rear pillar 1601 respectively by bolt groups. Then, hinge one end of the front diagonal brace 22 and the rear diagonal brace 21 to the crossbeam 23, and the other end to the corresponding large clamps 19.

[0072] S7: Secure the small clamp 20 to the front pillar 1602 and rear pillar 1601 with bolts. Note that the position of the small clamp 20 should be lower than the position of the large clamp 19.

[0073] S8: Lay the component cable 7 flat on the arc-shaped cover plate 1701 and install the component cable wire rope clamp 1801 to achieve a smooth connection between the component cable 7 and the pile cap structure 17. Lay the load-bearing cable 6 flat on the top cover plate 2304 and install the load-bearing cable wire rope clamp 1802 to achieve a smooth connection between the load-bearing cable 6 and the crossbeam structure 23. Lay the wind-resistant cable 5 flat on the mounting plate 2004 and install the wind-resistant cable wire rope clamp 25 to achieve a smooth connection between the wind-resistant cable 5 and the small clamp 20. At this point, the flexible photovoltaic support structure is able to cross the protruding mountain 15 via the newly added column structure 14.
