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 above the columns. The two parallel component cables are connected together 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 beams by a first anchoring clamp. 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 for driving the inclined beams to rotate is provided between the columns and the inclined beams.

[0008] The following are further optimizations of the above technical solution by this utility model: 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°.

[0009] According to the claim, a segmented adjustable tension flexible photovoltaic tracking bracket is characterized in that: the figure-eight-shaped connecting cable and the stabilizing cable form a double-triangle stabilizing structure, which is used to decompose the oblique tension into a horizontal constraint force and a vertical preload force.

[0010] Further optimization: Both ends of the component cable are connected to the inclined beams at both ends through a second anchoring clamp.

[0011] Further optimization: The rotating shaft assembly includes a bearing seat fixed to the top of the column, a rotating shaft fixedly installed inside the bearing seat, and an inclined beam rotatably sleeved on the rotating shaft.

[0012] Further optimization: At least one zipper assembly is connected to each of the opposite sides of the two end columns.

[0013] 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.

[0014] Further optimization: The cable assembly includes a stay cable, one end of which is connected to a connecting plate via a first tensioner, and the other end of which is connected to a fixing seat via a second tensioner. The fixing seat is fixed to the foundation or pile foundation.

[0015] 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 cables or stabilizing cables.

[0016] Further optimization: All corner points of the wind-resistant frame are located in the same plane, forming a stable planar support structure.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] This invention designs the stabilizing cable as a segmented structure and uses forked connecting cables at both ends for anchoring, forming modular units that work in conjunction with an independent wind-resistant frame. This allows for individual replacement of damaged stabilizing cables, preventing overall cable failure, and the figure-eight anchoring design limits the spread of damage. Furthermore, it supports segmented independent tensioning and adjustment to adapt to different terrains and load requirements, reducing construction difficulty. In addition, the modular units formed with the wind-resistant frame facilitate rapid disassembly and maintenance, significantly shortening the maintenance cycle and ensuring continuous and efficient system operation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1-2 As shown, a segmented adjustable tension flexible photovoltaic tracking bracket 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 column 1. The component cables 2 are connected together by multiple inclined beams 3. The top of the column 1 is hinged to the inclined beams 3 through a rotating shaft 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 7. Multiple wind-resistant frames 8 are arranged at intervals between two adjacent inclined beams 3. The wind-resistant frames 8 connect the component cables 2 and the stabilizing cables 5.

[0024] This design, firstly, by designing the stabilizing cable 5 as a segmented connection and anchoring it at both ends with a forked connecting cable 6, means that when a segment of the stabilizing cable 5 is damaged, only that segment needs to be replaced, avoiding the failure of the entire cable; at the same time, the figure-eight anchoring distributes the force, further limiting the spread of damage and reducing maintenance costs and system risks.

[0025] Secondly, the segmented stabilizing cable 5 and the independent wind-resistant frame 8 form a modular unit. During installation, only the tensioning and adjustment of each segment are required, without the need for overall synchronous operation, which reduces the requirements for large-span spaces and complex terrains.

[0026] Furthermore, the tension of each stabilizing cable 5 can be adjusted individually through the anchor points of the connecting cable 6 to adapt to the terrain undulations, load differences, or structural requirements of different sections.

[0027] Finally, localized damage only requires disassembling the corresponding section of the stabilizing cable 5 and wind-resistant frame 8, resulting in a small replacement work area and no need to dismantle the entire structure. At the same time, the anchoring design of the bifurcated connecting cable 6 facilitates quick disassembly and assembly, shortens the maintenance cycle, and maximizes the continuous operating efficiency of the photovoltaic system.

[0028] In this embodiment, the column 1 can be a foundation structure such as a concrete pile foundation or a steel structure column.

[0029] A drive device 9 for driving the inclined beam 3 to rotate is provided between the column 1 and the inclined beam 3.

[0030] 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 improving structural stability and drive efficiency.

[0031] 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 crossbeam and the column 1.

[0032] 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.

[0033] 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.

[0034] 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°~60°.

[0035] 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.

[0036] 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.

[0037] Both ends of the component cable 2 are connected to the inclined beams 3 at both ends through the second anchoring clamps 12.

[0038] This design enables a reliable connection between the component cable 2 and the inclined beam 3 through the second anchoring clamp 12, facilitating tension adjustment and ensuring structural stability.

[0039] 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.

[0040] In this embodiment, the cross-section of the bearing seat 41 is concave.

[0041] At least one zipper assembly 10 is provided on each of the opposite sides of the two end columns 1.

[0042] This design enhances structural stability through the zipper assembly 10, effectively balancing the force distribution on both sides of the columns 1.

[0043] In this embodiment, the number of zipper assemblies 10 is preferably three, wherein the middle zipper assembly 10 is connected to the rotating shaft 42, and the two zipper assemblies 10 on both sides are fixedly connected to the shaft seat 41 through the connecting plate 11.

[0044] The zipper assembly 10 includes a stay cable 101. One end of the stay cable 101 is connected to the connecting plate 11 or the rotating shaft 42 through a first tensioner 102. The other end of the stay cable 101 is connected to a fixing seat 104 through a second tensioner 103. The fixing seat 104 is fixed to the foundation or pile foundation.

[0045] In this embodiment, the fixing seat 104 can be fixed to the upper surface of the pile foundation by fasteners such as bolts.

[0046] 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.

[0047] In this embodiment, both the first tensioning member 102 and the second tensioning member 103 adopt U-shaped buckles.

[0048] 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.

[0049] The wind-resistant frame 8 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 hinged with a connector. The connectors are detachably connected to the corresponding component cable 2 or stabilizing cable 5.

[0050] All corner points of the wind-resistant frame 8 are located in the same plane, forming a stable planar support structure.

[0051] 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.
