Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a wind-resistant flexible photovoltaic bracket. Background Art

[0002] Photovoltaic mounting systems are specialized structures used to support, mount, and secure photovoltaic modules in solar photovoltaic power generation systems. Flexible photovoltaic mounting technology, as an emerging renewable energy solution, has garnered widespread attention and application worldwide in recent years. Traditional rigid photovoltaic mounting systems, due to their complex structure, high installation costs, and poor adaptability, limit their application in specific environments and geographical conditions. In contrast, flexible photovoltaic mounting systems, with their simple structure, lightweight materials, and strong adaptability, play a vital role in various photovoltaic projects.

[0003] Flexible photovoltaic racking systems typically consist of side columns, side beams, inter-column supports, diagonal braces, center columns, center beams, module cables, load-bearing cables, and inter-cable bracing. Flexible photovoltaic racking systems currently on the market generally have poor wind resistance in windy environments and lack effective wind load mitigation measures and optimized designs. Especially in high-wind areas, such as coastal areas or high-altitude regions, wind loads can significantly impact flexible photovoltaic racking systems, affecting their safety and long-term operational stability. Therefore, improving the wind resistance of flexible photovoltaic racking systems has become a pressing issue. Utility Model Content

[0004] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0005] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a wind-resistant flexible photovoltaic bracket, including a support mechanism and a plurality of wind-resistant mechanisms fixed on the support mechanism; the support mechanism includes a plurality of first bracket assemblies fixed on the ground and a plurality of second bracket assemblies fixed on the ground; the first bracket assembly and the second bracket assembly have the same structure; the first bracket assembly and the second bracket assembly are connected by an assembly cable and a load-bearing cable; the wind-resistant mechanism includes a plurality of counterweights, an adjustment assembly fixed on the counterweight, and a plurality of cable support assemblies fixed on the assembly cable and the load-bearing cable; the adjustment assembly and the cable support assembly are connected by a first guy cable and a second guy cable; adjacent cable support assemblies are connected by a connecting rod. Photovoltaic panels are mounted on component cables. Due to the large laying area of photovoltaic panels, they will block the wind. When encountering strong winds, the flexible bracket will bear a large wind load, and the component cables and load-bearing cables will shake. The cable support assembly can make the component cables and load-bearing cables always maintain a fixed distance. At the same time, adjacent cable support assemblies are connected by connecting rods to form a whole, avoiding collision between two adjacent rows of photovoltaic panels due to shaking and improving stability. The adjustment assembly can pull the cable support assembly. When the cable support assembly and the photovoltaic panel shake, the adjustment assembly can pull to avoid the cable support assembly engaging the photovoltaic panel and causing large shaking.

[0006] Specifically, the first bracket assembly includes a plurality of side columns fixed on the ground, side beams fixed on adjacent side columns, inter-column supports fixed on adjacent side columns, and diagonal braces fixed on the side columns.

[0007] Specifically, the cable support assembly includes a plurality of first aluminum alloy buckles, a second aluminum alloy buckle, and a plurality of cable support rods fixed on the first aluminum alloy buckle and the second aluminum alloy buckle.

[0008] Specifically, the adjustment assembly includes an anchor ring fixedly arranged on the counterweight, and a spring damper with one end rotatably sleeved on the anchor ring.

[0009] Specifically, the support mechanism further includes a plurality of center columns fixed on the ground and center beams fixed on adjacent center columns.

[0010] Specifically, the load-bearing cable is arranged in the middle and lower part of the adjacent component cables.

[0011] Specifically, the lengths of the struts between the cables are equal.

[0012] The beneficial effects of the utility model are:

[0013] (1) The connecting rods integrate the adjacent cable support assemblies into a whole, thereby improving the stability of the cable support assemblies under wind loads and preventing collisions between two adjacent rows of photovoltaic panels due to shaking.

[0014] (2) By adjusting the damping of the spring damper and then adjusting the traction force on the cable mechanism, the vibration amplitude under the action of wind is reduced, the wind load is effectively resisted, the stability of the bracket is improved, and the photovoltaic bracket is prevented from being damaged due to excessive wind load. It can also prevent the photovoltaic panel from being cracked or damaged due to wind vibration, and enhance the overall safety of the photovoltaic bracket structure.

[0015] (3) The number of spring dampers can be adjusted according to the span of the flexible bracket and the size of the local wind load. Spring dampers with different elastic stiffness and compression can also be selected according to different situations, making the practical flexible photovoltaic bracket more versatile.

[0016] (4) The spring damper has a simple structure and is easy to maintain. It can significantly improve the wind resistance of the flexible photovoltaic bracket at a low cost and improve the stability and reliability of the flexible photovoltaic bracket under extreme weather conditions.

[0017] (5) The lengths of the struts between cables are equal, that is, the inverted triangle formed by the component cables and the load-bearing cables is an equilateral triangle. When subjected to wind loads, the load can be evenly distributed to the three struts between cables, so that each strut between cables is evenly stressed, thus preventing some struts from breaking due to excessive loads.

[0033] Reference Figure 1-6As shown, the utility model describes a wind-resistant flexible photovoltaic bracket, comprising a support mechanism 1, and a plurality of wind-resistant mechanisms 4 fixed on the support mechanism; the support mechanism comprises a plurality of first bracket assemblies 11 fixed on the ground, and a plurality of second bracket assemblies 12 fixed on the ground; the first bracket assembly and the second bracket assembly have the same structure; the first bracket assembly and the second bracket assembly are connected by an assembly cable 2 and a load-bearing cable 3; the wind-resistant mechanism comprises a plurality of counterweights 41, an adjustment assembly 42 fixed on the counterweight, and a plurality of cable support assemblies 43 fixed on the assembly cable and the load-bearing cable; the adjustment assembly and the cable support assembly are connected by a first guy cable 44 and a second guy cable 45; adjacent cable support assemblies are connected by a connecting rod 46. The support mechanism is used to provide support and is installed on the ground; multiple component cables and load-bearing cables are installed on the support mechanism, photovoltaic panels are installed on the component cables, and the load-bearing cables are used to assist in bearing the weight; the wind-resistant mechanism is used to enhance the wind-resistant ability of the photovoltaic bracket; the counterweight is fixedly installed on the ground and is used to pull the adjustment component and the cable support component; the adjustment component can reduce the shaking amplitude of the cable mechanism under the action of wind and improve the stability of the bracket; the cable support component is used to support the component cables and the load-bearing cables; adjacent cable support components are connected by two connecting rods, so that multiple cable support components form a whole, which improves the stability of the cable support component under wind load and avoids collision between two adjacent rows of photovoltaic panels due to shaking.

[0034] Specifically, the first support assembly includes multiple side columns 111 fixed to the ground, side beams 112 fixed to adjacent side columns, inter-column supports 113 fixed to adjacent side columns, and diagonal braces 114 fixed to the side columns. The side columns are fixed to the ground; the side beams connect adjacent side columns; the inter-column supports and diagonal braces reinforce the side columns, making them more stable.

[0035] Specifically, the cable support assembly includes a plurality of first aluminum alloy buckles 431, a second aluminum alloy buckle 432, and a plurality of cable support rods 433 fixed on the first aluminum alloy buckle and the second aluminum alloy buckle. A single cable support assembly is provided with two first aluminum alloy clips and one second aluminum alloy clip; the first aluminum alloy clip is two-piece and connected by bolts and nuts; the second aluminum alloy clip is two-piece and connected by bolts and nuts; the assembly cable passes through the first aluminum alloy clip; the load-bearing cable passes through the second aluminum alloy clip; the first wind cable is connected to the first aluminum alloy clip; the second wind cable is connected to the second aluminum alloy clip; the inter-cable support rod is used to connect adjacent first aluminum alloy clips and second aluminum alloy clips to form an inverted triangle, and at the same time the inter-cable support rod can make the assembly cable and the load-bearing cable always maintain a fixed distance; adjacent cable support assemblies are connected by two connecting rods, which are cross-arranged, one end of the connecting rod is connected to the first aluminum alloy clip, and the other end is connected to the second aluminum alloy clip of the adjacent cable support assembly, and one end of the other connecting rod is connected to the second aluminum alloy clip, and the other end is connected to the first aluminum alloy clip of the adjacent cable support assembly.

[0036] Specifically, the adjustment component includes an anchor ring 421 fixed on the counterweight and a spring damper 422 with one end rotatably mounted on the anchor ring. One end of the spring damper is connected to the first and second wind cables.

[0037] Specifically, the support mechanism also includes a plurality of center columns 13 fixed to the ground and center beams 14 fixed to adjacent center columns. The center columns are fixed to the ground and serve as auxiliary support. Since photovoltaic panels are laid over a large area and the side columns are set far apart, the module cables and load-bearing cables are prone to falling.
