Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, specifically to a quick-installation steel cable flexible photovoltaic support. Background Technology

[0002] The flexible photovoltaic support frame adopts a method of tensioning prestressed steel cables between two fixed points. The two fixed points are provided with reaction force by a rigid foundation. There can be a large gap of 10 to 30 meters between the two fixed points. This design can avoid unfavorable factors such as mountainous terrain and high vegetation. The foundation points are set and the prestressed steel cables are tensioned only in suitable locations. At the same time, the foundation and flexible photovoltaic support frame can be constructed in deep ponds while keeping the water level unchanged.

[0003] A prior art patent with publication number CN118971733A discloses a solution including a column and a cable beam. A main cable and a secondary cable are tensioned on the cable beam. A cable support frame and a main cable pressure plate are fixedly installed on the main cable, and the cable support frame and the main cable pressure plate are fixedly connected. The cable support frame also has a secondary cable fixedly installed on it. Both sides of the main cable pressure plate are supported by damping springs. Spring guide posts sequentially and movably pass through one damping spring, the main cable pressure plate, and another damping spring and are installed on the component longitudinal beam. A sway-damping balance wing is also installed on the main cable. The sway-damping balance wing includes a main cable connecting arm fixedly installed on the two main cables. A rib plate support shaft is rotatably supported on the main cable connecting arm. A balance wing rib plate is fixedly installed on the rib plate support shaft. The outer end of the balance wing rib plate is fixedly covered with a balance wing skin, which is a symmetrically convex arc-shaped flat cylindrical surface. This bracket effectively reduces the damage to photovoltaic modules caused by vibration and swaying, making it particularly suitable for installation in strong wind environments.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, existing flexible photovoltaic supports rely on shock-absorbing structures to overcome the swaying of photovoltaic panels caused by slack steel cables and strong winds. However, in winter or summer, the elasticity of the shock-absorbing springs is affected by temperature, making it impossible to adjust the shock-absorbing elasticity of the structure according to different seasons.

[0006] Secondly, existing flexible photovoltaic brackets, due to the limitations of the photovoltaic panel fixing structure, cannot quickly assemble and disassemble the photovoltaic panels during the assembly process, which reduces the assembly efficiency on the construction site.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model solves the problem that in traditional flexible photovoltaic brackets, the use of shock-absorbing structures to overcome the swaying of photovoltaic panels under conditions of high wind speed and force, and the inability to adjust the shock-absorbing elasticity of the structure according to different seasons, is problematic.

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

[0010] A quick-installation steel cable flexible photovoltaic support includes a photovoltaic panel support frame.

[0012] The upper and lower ends of the photovoltaic panel support frame are respectively hinged to an upper positioning plate and a lower positioning plate that are swingable. When the upper positioning plate swings to a state parallel to the photovoltaic panel, it is locked by an upper positioning component. When the lower positioning plate swings to a state parallel to the photovoltaic panel, it is locked by a lower positioning component.

[0013] As an optimized solution, the steel cable quick-release seat includes two semi-circular brackets arranged vertically opposite each other. One of the opposite ends of the two semi-circular brackets is hinged together, and a connecting plate is fixedly connected to the outer wall of the other opposite end of the two semi-circular brackets. The two connecting plates are fixed together by a bolt assembly. The upper end of the upper semi-circular bracket is fixedly connected to the lower end of the support cylinder.

[0014] As an optimized solution, a sliding hole is provided axially on the side wall of the support cylinder, and a slider is fixedly connected to the side wall of the support column and slidably constrained within the sliding hole.

[0015] As an optimized solution, the outer wall of the support column is provided with an external thread that matches the opposing nut.

[0016] As an optimized solution, a connecting plate is fixed to the upper end of the support column, and the connecting plate is fixed to the lower end of the photovoltaic panel support frame by screws.

[0017] As an optimized solution, the photovoltaic panel support frame includes two parallel inclined side plates, a lower end plate is fixed between the upper surfaces of the lower ends of the two side plates, a bottom plate is fixed to the opposite inner walls of the two side plates, an upper end plate is slidably disposed between the two bottom plates along the inclined direction of the photovoltaic panel support frame, the upper end plate and the lower end plate abut against the upper and lower ends of the photovoltaic panel respectively, and the bottom plate abuts against the lower surface of the photovoltaic panel.

[0018] As an optimized solution, a fixing plate is fixedly connected to the upper end plate on the side wall away from the lower end plate. The fixing plate has a fixing hole. The bottom plate has a number of threaded holes arranged in parallel along the sliding direction of the upper end plate. Bolts are inserted into the fixing holes, and the ends of the bolts are threadedly connected to the threaded holes.

[0019] As an optimized solution, the upper positioning component includes upper locking plates fixed to both ends of the upper positioning plate, upper square locking blocks fixed to the opposite sidewalls of the upper end plate, upper locking plates having upper rectangular sliding holes, and upper circular unlocking holes having connected upper rectangular sliding holes at their lower ends, and upper square locking blocks being slidably constrained between the upper rectangular sliding holes and the upper circular unlocking holes.

[0020] As an optimized solution, the width of the upper rectangular sliding hole is the same as the width of the upper square locking block, and the diameter of the upper circular unlocking hole is greater than the diagonal length of the upper square locking block.

[0021] As an optimized solution, the lower positioning component includes lower locking plates fixed to both ends of the lower positioning plate, and lower square locking blocks fixed to the opposite side walls of the lower end plate. The lower locking plate has a lower rectangular sliding hole, and the lower end of the lower rectangular sliding hole has a connected lower circular unlocking hole. The lower square locking block is slidably constrained between the lower rectangular sliding hole and the lower circular unlocking hole.

[0022] As an optimized solution, the width of the lower rectangular sliding hole is the same as the width of the lower square locking block, and the diameter of the lower circular unlocking hole is greater than the diagonal length of the lower square locking block.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The quick-assembly bracket for steel cables includes two semi-circular brackets arranged vertically opposite each other. When assembly with a steel cable is required, the lower semi-circular bracket is opened, the upper semi-circular bracket is supported on the steel cable, and then the lower semi-circular bracket is closed. The upper and lower semi-circular brackets are used to hold and lock the steel cable in place. Finally, the two semi-circular brackets are fixed with bolts and connecting plates, which allows for quick assembly with the steel cable.

[0025] By setting opposing nuts that move along the axial direction on the support column, the damping spring can be compressed, and the damping distance of the damping spring can be adjusted. By adjusting the elasticity of the damping spring, the damping distance can be shortened when the elasticity is good in the high temperature environment of summer, and extended when the elasticity is poor in the low temperature environment of winter, thus improving the damping performance. It can be adjusted according to the external environment to improve the damping performance.

[0026] The upper plate can be adjusted in position using bolts to fix photovoltaic panels of different widths. When fixing the photovoltaic panel, the lower surface of the panel is supported on the base plate, with the lower end of the panel and the upper plate corresponding to each other. Then, the upper or lower positioning plate is swung to position the square locking block within the circular unlocking hole. The angle of the upper or lower positioning plate can then be adjusted to be parallel to the photovoltaic panel. Pushing the upper or lower positioning plate then positions the square locking block within the rectangular sliding hole, achieving locking. The upper or lower positioning plate can be kept horizontal with the photovoltaic panel, and the upper and lower surfaces of the photovoltaic panel are pressed together, effectively preventing the photovoltaic panel from falling off the support frame and improving assembly efficiency. When disassembling the photovoltaic panel, simply reverse the movement of the upper and lower positioning plates, swinging them to a perpendicular position to the photovoltaic panel, and the panel can be removed from the support frame, making assembly quick and easy.

[0046] The working principle of this device is as follows:

[0047] The quick-assembly bracket for steel cables includes two semi-circular brackets 6 arranged vertically opposite each other. When assembly with the steel cable is required, the lower semi-circular bracket 6 is opened, the upper semi-circular bracket 6 is supported on the steel cable, and then the lower semi-circular bracket 6 is closed.

Then, the two semi-circular brackets 6 are fixed by the bolt assembly 8 and the connecting plate 7, which can quickly complete the assembly with the steel cable.

[0048] By setting a counter nut 3 on the support column 2 that moves along its axial direction, the damping spring 4 is compressed, and the damping distance of the damping spring 4 is adjusted. By adjusting the elasticity of the damping spring 4, the damping distance can be shortened when the elasticity is good in the high temperature environment of summer, and the damping distance of the spring can be extended when the elasticity is poor in the low temperature environment of winter, thereby improving the damping performance. It can be adjusted according to the external environment to improve the damping performance.

Then, the upper positioning plate 15 or the lower positioning plate 14 is swung to make the square locking block position in the circular unlocking hole. At this time, the upper positioning plate 15 or the lower positioning plate 14 can be swung to adjust its angle. After adjusting it to a parallel angle with the photovoltaic panel 13, the upper positioning plate 15 or the lower positioning plate 14 is pushed to make the square locking block position in the rectangular hole. The upper positioning plate 15 or the lower positioning plate 14 is locked within the sliding hole, keeping it horizontal with the photovoltaic panel 13. The upper positioning plate 15 and the lower positioning plate 14 abut against each other, effectively preventing the photovoltaic panel 13 from falling off the photovoltaic panel 13 support frame and improving the assembly efficiency of the photovoltaic panel 13. When disassembling the photovoltaic panel 13, simply move the upper positioning plate 15 and the lower positioning plate 14 in the opposite direction and swing them to a perpendicular position to the photovoltaic panel 13 to remove the photovoltaic panel 13 from the photovoltaic panel 13 support frame, making assembly quick and easy.
