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 containing a damping device. 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:

[0003] 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.

[0004] 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.

[0005] 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.

[0006] 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.

[0007] In addition, existing flexible photovoltaic supports sway frequently and with large amplitude under wind suction, which can easily cause microcracks in the photovoltaic panels. Utility Model Content

[0008] The main technical problem to be solved by this utility model is to provide a segmented adjustable tension flexible photovoltaic tracking bracket with a damping device, so as to realize the individual replacement of local damage to the stabilizing cable, precise adjustment of segmented tension, reduce construction difficulty and maintenance costs, and suppress wind vibration.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] A segmented adjustable tension flexible photovoltaic tracking bracket with a damping device includes multiple columns arranged at intervals on the same straight line. At least two parallel component cables are arranged above the columns, and the component cables are connected by multiple inclined beams. The top of the column is hinged to the inclined beams through a rotating shaft assembly. A stabilizing cable is arranged between two adjacent inclined beams and below the component cables. Each end of the stabilizing cable branches into two connecting cables. The two connecting cables on the same side are arranged in a figure-eight shape and are jointly anchored to the corresponding inclined beam by a first anchoring clamp. Multiple wind-resistant frames and elastic damping components are alternately arranged between two adjacent inclined beams. The wind-resistant frames and elastic damping components are connected to the component cables and stabilizing cables, respectively. A driving device for driving the inclined beams to rotate is arranged between the columns and the inclined beams.

[0011] The following are further optimizations of the above technical solution by this utility model:

[0012] The elastic damping assembly includes at least two elastic damping structures, with each end of the elastic damping structure connected to a corresponding component cable and a stabilizing cable, respectively.

[0013] Further optimization: The elastic damping structure includes a counterweight block, with damping springs symmetrically fixedly connected to both ends of the counterweight block. The opposite ends of the two damping springs are respectively connected to the component cable and the stabilizing cable.

[0014] Further optimization: The connecting cable and the stabilizing cable are integrally formed, and the included angle between the two connecting cables on the same side is 30° to 60°.

[0015] Further optimization: The connecting cables and stabilizing cables arranged in a figure-eight shape form a double-triangle stabilizing structure, which is used to decompose the oblique tension into horizontal constraint force and vertical preload force.

[0016] Further optimization: The two ends of the component cable are respectively connected to the inclined beams at both ends through the second anchoring clamps.

[0017] Further optimization: The rotating shaft assembly includes a bearing seat fixedly connected to the top of the column, and a rotating shaft is fixedly installed inside the bearing seat. The rotating shaft is rotatably sleeved on the inclined beam.

[0018] Further optimization: At least one zipper assembly is provided on each of the opposite sides of the two end columns.

[0019] 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.

[0020] Further optimization: The wind-resistant frame includes 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 or stabilizing cable. All corner points of the wind-resistant frame are located in the same plane, forming a stable planar support structure.

[0021] This invention completely eliminates single-point dependence through a segmented stabilizing cable design. When a local cable segment is damaged by corrosion or impact, only the faulty segment needs to be replaced instead of the entire cable, which greatly reduces maintenance costs and system downtime risks, and ensures the continuous and stable operation of the support.

[0022] This utility model uses a figure-eight-shaped forked connecting cable combined with a modular anchoring clamp to achieve segmented, small-range tensioning. This eliminates the need for large equipment or high-precision overall cable adjustment during construction, making it particularly suitable for complex sites such as mountains and slopes, and significantly reducing installation difficulty and construction period.

[0023] This invention allows for segmented and differentiated force adjustment through independently anchored stabilizing cables. It can adjust the tension of connecting cables individually to address differences in terrain undulations, snow loads, or wind pressure in different sections, thereby optimizing the stress distribution of the structure and avoiding local overload or slack caused by a "one-size-fits-all" tension in the overall cable net.

[0024] This invention uses alternating elastic damping components to dynamically absorb and dissipate wind vibration energy, significantly suppressing the risk of support swaying and resonance, and improving the adaptability and safety of the structure in harsh wind environments.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0030] like Figure 1-2 As shown, a segmented adjustable tension flexible photovoltaic tracking bracket with a damping device includes multiple columns 1 arranged at intervals and located 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 top of the columns 1 is hinged to the inclined beams 3 through a pivot assembly 4. A stabilizing cable 5 is arranged between two adjacent inclined beams 3 and below the component cables 2. Two connecting cables 6 extend from each end of the stabilizing cable 5. The two connecting cables 6 on the same side are arranged in a figure-eight shape and are jointly anchored to the corresponding inclined beam 3 by a first anchoring clamp 12. Multiple wind-resistant frames 8 and elastic damping components are alternately arranged between two adjacent inclined beams 3. The wind-resistant frames 8 and elastic damping components are connected to the component cables 2 and the stabilizing cables 5, respectively.

[0031] This design, firstly, completely eliminates single-point dependence with its segmented stabilizing cable design. Thus, when a local cable segment is damaged by corrosion or impact, only the faulty segment needs to be replaced instead of the entire cable, significantly reducing maintenance costs and system downtime risks, and ensuring the continuous and stable operation of the support system.

[0032] Secondly, the figure-eight bifurcated connecting cable 6, combined with modular anchoring clamps, enables segmented small-range tensioning, thus eliminating the need for large equipment or high-precision overall cable adjustment during construction. This is especially suitable for complex sites such as mountains and slopes, significantly reducing installation difficulty and construction period.

[0033] Furthermore, the independently anchored stabilizing cable 5 allows for segmented and differentiated force adjustment. Depending on the terrain undulations, snow load, or wind pressure differences in different sections, the tension of the connecting cable 6 can be adjusted individually to optimize the structural stress distribution and avoid local overload or slack caused by the "one-size-fits-all" tension of the integral cable net.

[0034] Finally, the alternating arrangement of elastic damping components can dynamically absorb and dissipate wind vibration energy, significantly suppressing the risk of support swaying and resonance, and improving the structure's adaptability and safety in harsh wind environments.

[0035] In this embodiment, the column 1 can be a foundation structure such as a concrete pile foundation or a steel structure column.

[0036] A drive device 9 for driving the inclined beam 3 to rotate is provided between the column 1 and the inclined beam 3.

[0037] This design enables the inclined beam 3 to rotate via the drive device 9, ensuring that the photovoltaic modules accurately track the sun's position while simultaneously improving structural stability and drive efficiency.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] The elastic damping assembly includes at least two elastic damping structures 7, with each end of the elastic damping structure 7 connected to a corresponding component cable 2 and a stabilizing cable 5, respectively.

[0042] The elastic damping structure 7 includes a counterweight 71, with damping springs 72 symmetrically fixed at both ends of the counterweight 71. The opposite ends of the two damping springs 72 are respectively connected to the component cable 2 and the stabilizing cable 5.

[0043] This design, through the symmetrical arrangement of damping springs 72 and counterweights 71, achieves bidirectional buffering and vibration reduction and enhanced dynamic stability, effectively absorbing bidirectional vibration and impact loads, suppressing high-frequency vibration and reducing the risk of resonance; at the same time, the coordinated work of multiple elastic damping structures 7 makes the load distribution more balanced, avoids stress concentration, and extends service life.

[0044] The connecting cable 6 and the stabilizing cable 5 are integrally formed, and the included angle between the two connecting cables 6 on the same side is 30° to 60°.

[0045] This design, with its integrated molding, forms a high-strength whole between the connecting cable 6 and the stabilizing cable 5, avoiding weak joints and improving tensile strength and durability. The bifurcation angle of 30° to 60° evenly distributes the tension to the inclined beam 3, reducing stress concentration and enhancing wind resistance and deformation resistance. At the same time, the integrated structure simplifies the installation process, and the bifurcation angle provides construction flexibility and facilitates tension adjustment. In addition, this angle range takes into account different needs; around 30° is suitable for high-tension sections, while around 60° adapts to terrain undulations or flexible adjustments, enhancing overall adaptability.

[0046] The figure-eight-shaped connecting cable 6 and the stabilizing cable 5 form a double-triangle stabilizing structure, which is used to decompose the oblique tension into horizontal constraint force and vertical preload force.

[0047] The two ends of the component cable 2 are respectively connected to the inclined beams 3 at both ends through the second anchoring clamps 13.

[0048] This design enables a reliable connection between the component cable 2 and the inclined beam 3 through the second anchoring clamp 13, facilitating tension adjustment and ensuring structural stability.

[0049] The rotating shaft assembly 4 includes a bearing seat 41 fixedly connected to the top of the column 1, and a rotating shaft 42 fixedly installed inside the bearing seat 41. The rotating shaft 42 is rotatably sleeved on the inclined beam 3.

[0050] In this embodiment, the cross-section of the bearing seat 41 is concave.

[0051] At least one cable assembly 10 is provided on each of the opposite sides of the two end columns 1.

[0052] This design enhances structural stability through the cable assembly 10, effectively balancing the force distribution on both sides of the columns 1.

[0053] In this embodiment, the number of cable assemblies 10 is preferably three, wherein the middle cable assembly 10 is connected to the rotating shaft 42, and the cable assemblies 10 on both sides are fixedly connected to the bearing seat 41 through the connecting plate 11.

[0054] 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 42 via a first tensioner 102. The other end of the stay cable 101 is connected to a fixing seat 104 via a second tensioner 103. The fixing seat 104 is fixed to the foundation or pile foundation.

[0055] In this embodiment, the fixing seat 104 can be fixed to the upper surface of the pile foundation by fasteners such as bolts.

[0056] 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.

[0057] In this embodiment, both the first tensioning member 102 and the second tensioning member 103 adopt U-shaped buckles.

[0058] In other embodiments, the first tensioning member 102 and the second 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.

[0059] 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 5.

[0060] All corner points of the wind-resistant frame 8 are located in the same plane, forming a stable planar support structure.

[0061] 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.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
