[0076] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0077] The principle of the photovoltaic bracket 1000 proposed in this application is described in detail below:

[0078] In the related art, the tooling scheme of the cable is to crimp an extrusion anchor at a certain distance from the end of the cable body. The extrusion anchor serves as a permanent anti-slip part. The two-petal clamp is clamped on the permanent anti-slip part, and the clamp and the power equipment are connected by a traction rope for traction and tensioning. Before crimping the extrusion anchor, a section of the sheath of the cable body needs to be peeled off to expose the inside of the cable body as the crimping part of the extrusion anchor. The crimping part of the extrusion anchor is easy to wear, and has poor corrosion resistance and stability. The extrusion anchor is a disposable tooling part and cannot be disassembled and reused. The extrusion anchor after crimping also needs to be anti-corrosion treated. The process is relatively complicated and the construction cost is high.

[0079] In order to solve this technical problem, the present application provides a photovoltaic bracket 1000, which is described below with reference to Figures 1-9 A photovoltaic bracket 1000 according to an embodiment of the present application is described.

[0080] like Figure 1-Figure 4 As shown, the photovoltaic bracket 1000 of the embodiment of the present application includes: a first end support frame 110, a second end support frame 120, a cable 200 and a cable holding device 300.

[0081] The first end support frame 110 and the second end support frame 120 are disposed opposite to each other, and the first end support frame 110 and the second end support frame 120 are fixed to the ground.

[0082] like Figure 3 and Figure 4As shown, the cable 200 includes a cable body 210 , a first anchor 220 and a second anchor 230 .

[0083] The cable body 210 may be made of various materials, including high-strength materials such as steel strands and carbon fibers.

[0084] The cable body 210 in this embodiment is a steel strand, which has high strength, good toughness and wear resistance.

[0085] The first anchor 220 and the second anchor 230 are connected to both ends of the cable body 210 .

[0086] The first anchor 220 and the second anchor 230 can be ear-insertion anchors, clip-type anchors, extrusion anchors, etc.

[0087] In this embodiment, an ear-insertion type anchor is selected, which has good durability and strong bearing capacity.

[0088] The first anchor 220 is connected to the first end support frame 110, and the second anchor 230 is connected to the second end support frame 120. The first anchor 220 and the second anchor 230 are used to connect the cable body 210 between the first end support frame 110 and the second end support frame 120 that are oppositely arranged.

[0089] The cable holding device 300 includes a connecting structure 310 .

[0090] The cable gripping device 300 clamps the cable body 210 .

[0091] The connecting structure 310 on the rope-holding device 300 is used to connect the traction rope 400 .

[0092] In the related art, the tooling scheme of the cable is to crimp an extrusion anchor at a certain distance from the end of the cable body. The extrusion anchor serves as a permanent anti-slip part. The two-petal clamp is clamped on the permanent anti-slip part, and the clamp and the power equipment are connected by a traction rope for traction and tensioning. Before crimping the extrusion anchor, a section of the sheath of the cable body needs to be peeled off to expose the inside of the cable body as the crimping part of the extrusion anchor. The crimping part of the extrusion anchor is easy to wear, and has poor corrosion resistance and stability. The extrusion anchor is a disposable tooling part and cannot be disassembled and reused. The extrusion anchor after crimping also needs to be anti-corrosion treated. The process is relatively complicated and the construction cost is high.

[0093] The rope body 210 of this embodiment is suspended on the second end support frame 120 through the second anchor 230, and the rope holding device 300 clamps the rope body 210 at a certain distance from the first anchor 220. The connecting structure 310 on the rope holding device 300 is connected to the traction rope 400, and the traction rope 400 is tensioned by an external power device, so that the first anchor 220 at the end not connected to the first end support frame 110 is pulled up until it is fixed to the first end support frame 110. In this embodiment, the rope holding device 300 directly clamps the rope body 210, and there is no need to remove the outer sheath of the rope body 210. The clamping part is not easy to wear and has good corrosion resistance and stability. After the second anchor 230 is connected to the second end support frame 120, the rope holding device 300 can be directly pulled by the traction rope 400 to tension the rope body 210. The process is simple and the cost is low.

[0094] According to the photovoltaic bracket 1000 provided in the embodiment of the present application, it is suspended on the second end support frame 120 through the second anchor 230, and the traction rope 400 pulls the rope holding device 300 and then tensions the rope body 210, so that the first anchor 220 is connected to the first end support frame 110. The process is simple and the cost is low, and the rope 200 is not easy to wear and has good corrosion resistance and stability.

[0095] In some embodiments, as Figure 5-Figure 7 As shown, the rope holding device 300 may include a first holding hoop 320 and a second holding hoop 330 .

[0096] The first clamp 320 and the second clamp 330 can be made of materials such as carbon steel, stainless steel, cast iron, aluminum alloy and high-strength plastic.

[0097] In this embodiment, the first clamp 320 and the second clamp 330 are made of stainless steel. The stainless steel first clamp 320 and the second clamp 330 have good corrosion resistance and high-temperature oxidation resistance, and good durability.

[0098] like Figure 6 As shown, the first clamp 320 is formed with a first groove 321 , and the second clamp 330 is formed with a second groove 331 .

[0099] The first groove 321 and the second groove 331 are used to accommodate the cable body 210 .

[0100] The second clamp 330 is detachably connected to the first clamp 320 .

[0101] The second groove 331 is disposed opposite to the first groove 321 . The second groove 331 and the first groove 321 together form an accommodating cavity. The cable body 210 is clamped in the accommodating cavity surrounded by the second groove 331 and the first groove 321 .

[0102] The connecting structure 310 may be provided on the first clamp 320 , the connecting structure 310 may be provided on the second clamp 330 , or the connecting structure 310 may be provided on the first clamp 320 and the second clamp 330 .

[0103] In this embodiment, the connecting structure 310 is provided on the first clamp 320 and the second clamp 330, so that the traction rope 400 has better stability when being pulled.

[0104] like Figure 6 As shown, in this embodiment, the first groove 321 and the second groove 331 extend along the first direction, and the first groove 321 and the second groove 331 pass through both ends of the first clamp 320 and the second clamp 330 respectively.

[0105] It can be understood that the first direction is the length direction of the first clamp 320 and the second clamp 330. The extension of the first groove 321 and the second groove 331 along the first direction can increase the length of the first groove 321 and the second groove 331, thereby increasing the contact area with the cable body 210 and increasing friction, so that the cable body 210 is not easy to slip or wear.

[0106] According to the photovoltaic bracket 1000 provided in the embodiment of the present application, the cable body 210 is accommodated by the first groove 321 and the second groove 331 set on the first clamp 320 and the second clamp 330, so that the first clamp 320 and the second clamp 330 can clamp the cable body 210. At the same time, the first clamp 320 and the second clamp 330 are detachably connected, which is easy to disassemble and maintain.

[0107] In some embodiments, as Figure 6 and Figure 7 As shown, the first groove 321 and the second groove 331 may be provided with anti-slip grooves 3211 .

[0108] The first groove 321 and the second groove 331 may be in at least one of the following structural forms:

[0109] First, the first groove 321 is provided with an anti-slip groove 3211 , while the second groove 331 is not provided with an anti-slip groove 3211 .

[0110] In this embodiment, the anti-slip grooves 3211 of the first grooves 321 increase the friction between the cable holding device 300 and the cable body 210 , thereby preventing the cable holding device 300 and the cable body 210 from slipping, scratching or tearing the cable body 210 .

[0111] Second, the first groove 321 is not provided with the anti-slip groove 3211 , while the second groove 331 is provided with the anti-slip groove 3211 .

[0112] In this embodiment, the anti-slip grooves 3211 of the second grooves 331 increase the friction between the cable holding device 300 and the cable body 210 , thereby preventing the cable holding device 300 and the cable body 210 from slipping, scratching or tearing the cable body 210 .

[0113] Third, if Figure 6 and Figure 7 As shown, both the first groove 321 and the second groove 331 are provided with anti-slip grooves 3211 .

[0114] In this embodiment, the anti-slip grooves 3211 of the first groove 321 and the second groove 331 increase the friction between the surface of the cable holding device 300 and the cable body 210, thereby preventing the cable holding device 300 and the cable body 210 from slipping, scratching or tearing the cable body 210. The first groove 321 and the second groove 331 are both provided with anti-slip grooves 3211, and the anti-slip effect is better.

[0115] In this embodiment, both the first groove 321 and the second groove 331 are provided with anti-slip grooves 3211 , and the anti-slip grooves 3211 are threads.

[0116] The threads can be trapezoidal, buttress, or other non-standard thread shapes.

[0117] In this embodiment, the anti-slip pattern 3211 adopts a trapezoidal thread. The trapezoidal thread has high root strength, can withstand a large load, has good self-locking performance, and has high connection firmness and reliability.

[0118] According to the photovoltaic bracket 1000 provided in the embodiment of the present application, the anti-slip grooves 3211 provided in the first groove 321 and the second groove 331 increase the friction between the surface of the cable holding device 300 and the cable body 210, thereby preventing the cable holding device 300 and the cable body 210 from slipping, scratching or tearing the cable body 210.

[0119] In some embodiments, as Figure 6 As shown, the photovoltaic bracket 1000 may further include a lock buckle 500 , and the connection structure 310 may include a first hole 311 and a second hole 312 .

The first hole 311 and the second hole 312 are arranged at one end to facilitate the connection between the rope holding device 300 and the traction rope 400, and the traction rope 400 will not interfere with the rope body 210.

[0123] The first hole 311 and the second hole 312 are detachably connected to the lock buckle 500 , and the lock buckle 500 is connected to one end of the traction rope 400 .

[0124] In this embodiment, the lock buckle 500 is a shackle.

[0125] The shackles can be straight shackles or oval shackles.

[0126] In this embodiment, an oval shackle is selected to facilitate connection with the traction rope 400.

[0127] According to the photovoltaic bracket 1000 provided in the embodiment of the present application, the first hole 311 and the second hole 312 are detachably connected to the lock buckle 500, which facilitates the connection and disassembly of the traction rope 400 and the rope holding device 300.
