Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a flexible support wind-resistant cable end connection structure and a flexible support. Background Art

[0002] In recent years, flexible photovoltaic racks, with their large spans, high clearances, and excellent terrain adaptability, have become increasingly popular in mountainous, fishpond, and desert photovoltaic applications. Flexible photovoltaic racks replace the purlins of traditional racks with galvanized steel strands. While this improves the rack's adaptability to complex terrain, the steel strands' inherent low stiffness, light weight, and large spans significantly impact wind resistance. Therefore, wind resistance is crucial to the design of flexible photovoltaic racks.

[0003] Currently, most designers use recurved steel wire ropes as wind-resistant cables to prevent large displacement of the flexible support steel strands under wind loads. During construction and installation, the wind-resistant cables often only need to be in a tensioned state, without applying a large initial tension. This is because applying a large initial tension increases the cost of the flexible support foundation, and the tensioned wind-resistant cables can provide good wind protection. However, simply tensioning the wind-resistant cable wire ropes is a task that cannot be completed by manpower alone, and often requires the use of a tensioning machine. The flexible support construction environment is complex, and it is difficult for operators to use machinery to pre-tighten all the wind-resistant cables. This makes construction very difficult and the construction quality is difficult to guarantee. Summary of the Invention

[0027] In recent years, flexible photovoltaic racks, with their large spans, high clearances, and excellent terrain adaptability, have become increasingly popular in mountainous, fishpond, and desert photovoltaic applications. Flexible photovoltaic racks replace the purlins of traditional racks with galvanized steel strands. While this improves the rack's adaptability to complex terrain, the steel strands' inherent low stiffness, light weight, and large spans significantly impact wind resistance. Therefore, wind resistance is crucial to the design of flexible photovoltaic racks.

[0028] Currently, most designers use recurved steel wire ropes as wind-resistant cables to prevent large displacement of the flexible support steel strands under wind loads. During construction and installation, the wind-resistant cables often only need to be in a tensioned state, without applying a large initial tension. This is because applying a large initial tension increases the cost of the flexible support foundation, and the tensioned wind-resistant cables can provide good wind protection. However, simply tensioning the wind-resistant cable wire ropes is a task that cannot be completed by manpower alone, and often requires the use of a tensioning machine. The flexible support construction environment is complex, and it is difficult for operators to use machinery to pre-tighten all the wind-resistant cables. This makes construction very difficult and the construction quality difficult to control.

[0029] Reference Figure 1 The present application provides a flexible support anti-wind cable end connection structure, including a pipe pile clamp 100 and an anti-wind cable 710. The pipe pile clamp 100 includes two clamps 110 and two fasteners 120. Connecting ears 111 are set on both sides of the clamp 110. The two clamps 110 are used to clamp on the pipe pile 510. The connecting ears 111 of the two clamps 110 are connected by fasteners 120, and the anti-wind cable 710 is connected to the fasteners 120 through basket bolts 400.

[0030] The present application connects the wind-resistant cable 710 to the fastener 120 on the pipe pile clamp 100 through the basket bolt 400. By tightening the basket bolt 400, the wind-resistant cable 710 can be initially tensioned, so that the wind-resistant cable 710 is initially in a tensioned state, which has a better wind-resistant effect. The installation of the basket bolt 400 can be completed manually without the help of a tensioning machine, and the construction is more convenient. At the same time, by checking the thread spacing of the basket bolt 400, the construction quality of the installation of the wind-resistant cable 710 can be controlled, making it easier to control the quality of the project.

[0031] The wind-resistant rope 710 is generally a steel strand with a diameter of 8 mm.

[0032] In some embodiments, the fastener 120 is an eye screw. The turnbuckle 400 on the wind-resistant cable 710 is more conveniently connected to the eye screw, saving the cost of anchors and lowering the connection cost.

[0033] Of course, the fastener 120 can also be configured as a bolt with other structures, such as a hook bolt, a U-bolt, etc.

[0034] Reference Figure 2 The present application also provides a flexible bracket, including a column device 500, a photovoltaic panel support device 600 and a wind-resistant component 700. There are at least two column devices 500, and each column device 500 is arranged at intervals. The column device 500 includes a pipe pile 510 and a cross arm 520. The cross arm 520 is fixed on the top of the pipe pile 510. The photovoltaic panel support device 600 includes two photovoltaic panel support cables 610. The ends of the cross arms 520 of two adjacent column devices 500 are connected by the photovoltaic panel support cable 610. The wind-resistant component 700 includes the above-mentioned wind-resistant cable 710, and the wind-resistant cable 710 is connected to the pipe pile 510 through the above-mentioned pipe pile clamp 100.

[0035] During the installation of this flexible bracket, the installation of the wind-resistant cable 710 is more convenient and saves more manpower.

[0036] In the embodiment shown in the present application, two column devices 500 are provided, the middle part of the cross arm 520 is horizontally fixed on the top of the pipe pile 510, the ends of the cross arms 520 of the two column devices 500 are connected by a photovoltaic panel support cable 610, the two photovoltaic panel support cables 610 are arranged in parallel, and the two photovoltaic panel support cables 610 and the two cross arms 520 form a rectangular structure, and the photovoltaic panels 300 are laid on the two photovoltaic panel support cables 610 in sequence along the length direction of the photovoltaic panel support cables 610.

[0037] In some embodiments, two wind-resistant cables 710 are provided, and the middle portions of the two wind-resistant cables 710 are respectively connected to the middle portions of two photovoltaic panel support cables 610. The wind-resistant cables 710 can pull the photovoltaic panel support cables 610, thereby improving the wind resistance of the entire photovoltaic panel support device 600 and making the photovoltaic panel 300 mounted on the photovoltaic panel support device 600 more stable.

[0038] In some embodiments, the flexible support further includes a support member 200, the ends of which are connected to the connection points of the two wind-resistant cables 710 and the two photovoltaic panel support cables 610. The support member 200 primarily provides support, enhancing the load-bearing capacity of the two photovoltaic panel support cables 610. It also enables the two photovoltaic panel support cables 610 of the photovoltaic panel support device 600 to remain parallel, allowing for more precise placement of the photovoltaic panel 300 on the two photovoltaic panel support cables 610.

[0039] In some embodiments, the flexible bracket also includes a load-bearing cable 800, which is located below the photovoltaic panel support device 600. The two ends of the load-bearing cable 800 are respectively connected to the cross arms 520 of two adjacent column devices 500, and the middle part of the load-bearing cable 800 is connected to the support member 200.

[0040] Specifically, the two ends of the load-bearing cable 800 are respectively connected to the middle of the crossarm 520 of the two adjacent column devices 500. The load-bearing cable 800 supports the photovoltaic panel support device 600 in the middle of the photovoltaic panel support device 600 through the support member 200, mainly bearing the pressure generated by the wind load. At the same time, the load-bearing cable 800 can also make the photovoltaic panel support cable 610 more horizontal, and the installed photovoltaic panel 300 more flat.

[0041] The load-bearing cable 800 is generally a 15.2mm steel strand.

[0042] In some embodiments, the support member 200 is a tripod structure, with the two bottom corners of the support member 200 connected to the connection points of the two wind-resistant cables 710 and the two photovoltaic panel support cables 610, respectively, and the top corner of the support member 200 connected to the middle of the load-bearing cable 800. The triangular structure of the support member 200 provides greater stability.

[0043] In the present application, the support member 200 is formed by welding a steel structure.

[0044] Of course, the support member 200 can also be configured as other structures, such as other polygonal structures such as a pentagon or a hexagon.

[0045] In some embodiments, the column device 500 further includes a diagonal brace 530, one end of which is fixedly connected to the cross arm 520, and the other end of which is fixedly connected to the pipe pile 510. The diagonal brace 530 strengthens the connection between the cross arm 520 and the pipe pile 510, thereby improving the stability of the cross arm 520.

[0046] Specifically, in the present application, both ends of the cross arm 520 are fixedly connected to the pipe pile 510 through the diagonal bracing rod 530 .
