Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a segmented adjustable tension flexible photovoltaic tracking bracket. Background Technology

[0002] In photovoltaic (PV) power generation systems, the stability of the PV support structure is crucial to the system's safety and power generation efficiency. Currently, the commonly used stabilizing cables in PV supports are typically designed as a single, continuous cable across the entire support structure to enhance its resistance to wind, snow loads, and deformation. However, this monolithic stabilizing cable design has some limitations in practical applications: First, if a section of the stabilizing cable is damaged due to corrosion, mechanical damage, or accidental impact, the entire stabilizing cable may fail, thereby affecting the stability of the entire support system and increasing maintenance costs and risks.

[0003] Secondly, the integral stabilizing cable requires a large tensioning space and high construction precision during installation and subsequent adjustment, especially in complex terrain or large-span support systems, where construction is more difficult.

[0004] Third, different sections of the photovoltaic support may require different tension adjustments due to differences in terrain, load distribution or structure, but the integral stabilizing cable is difficult to adjust independently in sections, affecting the overall optimization of the structure.

[0005] Fourth, if the stabilizing cable is partially damaged, it usually needs to be replaced entirely, which not only wastes materials but also has a long construction period, affecting the normal operation of the photovoltaic system. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a segmented adjustable tension flexible photovoltaic tracking bracket, so as to realize the individual replacement of local damage to the stabilizing cable and the precise adjustment of segmented tension, thereby reducing construction difficulty and maintenance costs.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A segmented adjustable tension flexible photovoltaic tracking bracket includes multiple columns arranged at intervals and on the same straight line. At least two parallel component cables are arranged on the top of the columns. The component cables are connected by multiple inclined beams. A rotating shaft is rotatably sleeved in the middle of the inclined beams. The top of the columns is fixedly connected to the rotating shaft through a bearing seat. A stabilizing cable is arranged between two adjacent inclined beams. The two ends of the stabilizing cable are respectively connected to the corresponding rotating shaft through a first tensioning member. Multiple wind-resistant frames are arranged at intervals between two adjacent inclined beams. The wind-resistant frames connect the component cables and the stabilizing cables. A driving device is arranged between the columns and the inclined beams to drive the inclined beams and the rotating shaft to rotate synchronously.

[0008] The following are further optimizations of the above technical solution by this utility model: Both ends of the component cable are connected to the inclined beam via anchoring clamps.

[0009] Further optimization: At least one cable assembly is connected to each of the opposite sides of the two end columns.

[0010] Further optimization: The number of zipper assemblies is three, wherein the middle zipper assembly is connected to the rotating shaft, and the two zipper assemblies on both sides are fixedly connected to the shaft seat through connecting plates.

[0011] Further optimization: The cable assembly includes a stay cable, one end of which is connected to a connecting plate via a second tensioner, and the other end of which is connected to a fixing seat via a third tensioner. The fixing seat is fixed to the foundation or pile foundation.

[0012] Further optimization: The wind-resistant frame includes a rigid frame consisting of at least three rods, with a connector at each corner of the rigid frame, and the connectors are detachably connected to the component cable or stabilizing cable respectively.

[0013] Further optimization: All corner points of the wind-resistant frame are located in the same plane, forming a stable planar support structure.

[0014] This invention connects the stabilizing cable in segments between adjacent inclined beams, ensuring that local damage affects only a single segment rather than the entire system. This significantly reduces maintenance risks and costs, and improves system reliability. Furthermore, the segmented stabilizing cable eliminates the need for extensive tensioning during installation, adapting to complex terrain and large-span scenarios, reducing construction precision requirements, and simplifying the operation process. In addition, the tension of each stabilizing segment can be adjusted independently, flexibly addressing differences in terrain or load across different sections, achieving localized optimization of structural performance, and enhancing overall adaptability. Local damage only requires replacement of the corresponding segment, avoiding the need to replace the entire cable, reducing material waste and downtime, and ensuring the efficient operation of the photovoltaic system.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, a segmented adjustable tension flexible photovoltaic tracking bracket includes multiple columns 1 arranged at intervals and on the same straight line. At least two parallel component cables 2 are arranged above the columns 1. The component cables 2 are connected together by multiple inclined beams 3. The middle of each inclined beam 3 is rotatably fitted with a rotating shaft 4. The top of the column 1 is fixedly connected to the rotating shaft 4 through a bearing 5. A stabilizing cable 6 is arranged between two adjacent inclined beams 3 and below the component cables 2. The two ends of the stabilizing cable 6 are respectively connected to the corresponding rotating shaft 4 through a first tensioning member 7. Multiple wind-resistant frames 8 are arranged at intervals between two inclined beams 3. The wind-resistant frames 8 connect the component cables 2 and the stabilizing cables 6.

[0021] This design, firstly, by connecting the stabilizing cable 6 in segments between adjacent inclined beams 3, ensures that local damage only affects a single segment rather than the whole system, significantly reducing maintenance risks and costs and improving system reliability.

[0022] Secondly, the segmented stabilizing cable 6 does not require extensive tensioning during installation, making it suitable for complex terrain and large-span scenarios, reducing construction accuracy requirements and simplifying the operation process.

[0023] Furthermore, the tension of each stabilizing cable 6 can be adjusted individually to flexibly respond to differences in terrain or load in different sections, thereby achieving local optimization of structural performance and improving overall adaptability.

[0024] Finally, localized damage only requires replacement of the corresponding section, avoiding the need to replace the entire cable, reducing material waste and downtime, and ensuring the efficient operation of the photovoltaic system.

[0025] In this embodiment, the column 1 can be a foundation structure such as a concrete pile foundation or a steel structure column.

[0026] A drive device 9 is provided between the column 1 and the inclined beam 3 to drive the inclined beam 3 and the rotating shaft 4 to rotate synchronously.

[0027] This design enables synchronous linkage between the inclined beam 3 and the rotating shaft 4 through the drive device 9, ensuring that the photovoltaic module accurately tracks the sun's position while improving structural stability and drive efficiency.

[0028] In this embodiment, the driving device 9 is an electric push rod, and the two ends of the electric push rod are respectively hinged to the inclined beam 3 and the column 1.

[0029] In other embodiments, the drive device 9 may also be one of a hydraulic cylinder, a gear motor, a linear motor, a wire rope winch, or a pneumatic cylinder.

[0030] In this embodiment, a first hinge seat is fixedly installed on the column 1, and a second hinge seat is fixedly connected to the bottom of one end of the inclined beam 3. The two ends of the electric push rod are respectively hinged to the first hinge seat and the second hinge seat through pins.

[0031] In this embodiment, the cross-section of the bearing seat 5 is concave.

[0032] Both ends of the component cable 2 are connected to the inclined beams 3 at both ends by anchoring clamps 12.

[0033] This design enables a reliable connection between the component cable 2 and the inclined beam 3 through the anchoring clamp 12, facilitating tension adjustment and ensuring structural stability.

[0034] At least one cable assembly 10 is connected to each of the two opposing sides of the column 1.

[0035] This design enhances structural stability through the cable assembly 10, effectively balancing the force distribution on both sides of the columns 1.

[0036] In this embodiment, three cable assemblies 10 are preferably provided, wherein the middle cable assembly 10 is connected to the rotating shaft 4, and the cable assemblies 10 on both sides are fixedly connected to the bearing seat 5 through the connecting plate 11.

[0037] The cable assembly 10 includes a stay cable 101. One end of the stay cable 101 is connected to a connecting plate 11 or a rotating shaft 4 via a second tensioner 102. The other end of the stay cable 101 is connected to a fixing seat 104 via a third tensioner 103. The fixing seat 104 is fixed to the foundation or pile foundation.

[0038] In this embodiment, the fixing seat 104 can be fixed to the upper surface of the pile foundation by fasteners such as bolts.

[0039] In other embodiments, the fixing seat 104 is fixed to the pile foundation, and the fixing seat 104 is pre-embedded in the pile foundation to achieve a fixed connection between the fixing seat 104 and the pile foundation.

[0040] The wind-resistant frame 8 comprises a rigid frame consisting of at least three rods connected end to end. The rigid frame has at least three corner points, and each corner point is connected to a connector. The connectors are detachably connected to the corresponding component cable 2 or stabilizing cable 6.

[0041] All corner points of the wind-resistant frame 8 are located in the same plane, forming a stable planar support structure.

[0042] This design, through the synergistic effect of the rigid frame and the flexible cable structure, ensures wind resistance stability while allowing the support system to rotate flexibly with the drive device 9 and effectively disperses wind loads.

[0043] In this embodiment, the first tensioning member 7, the second tensioning member 102, and the third tensioning member 103 all adopt U-shaped buckles.

[0044] In other embodiments, the first tensioning member 7, the second tensioning member 102, and the third tensioning member 103 may also adopt structures such as turnbuckles, wedge anchors, threaded sleeves, and quick-release buckles to meet the tension adjustment and connection requirements under different working conditions.
