With this market development, flexible support systems have emerged, enabling the construction of photovoltaic power stations in complex locations such as gullies, hillsides, and sewage treatment plants, offering a wide range of applications. However, flexible support systems are sensitive to wind loads and require a sufficient wind-resistant stabilization system to ensure the safe operation of photovoltaic modules under wind loads. Wind-resistant stabilization systems are generally spatial structures made of round or square steel tubes. These systems are crucial to flexible support systems, and ensuring a reliable connection between the wind-resistant stabilization system and the steel cables is a pressing problem that needs to be solved.

[0033] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

Figure 2 for Figure 1 A schematic diagram of the node connection on the front elevation; Figure 3 for Figure 1 A schematic diagram of the side elevation of the node connection; Figure 4 for Figure 1 A schematic diagram of the spatial structure of irregularly shaped fasteners. (See attached diagram.) Figure 1-4 As shown, a method for fixing a steel pipe and a flexible support cable according to the present invention includes the following steps:

[0035] Step S1: Two irregularly shaped fasteners 3 are placed facing each other, and the steel cable is clamped by the toothed grooves formed by the two irregularly shaped fasteners 3; a gap should be left between the two irregularly shaped fasteners 3 during installation.

[0036] Each of the irregularly shaped fasteners 3 includes:

[0037] The upper clamping part 301 has a clamping tooth groove 302 on one side, and the clamping tooth groove 302 is provided opposite to the clamping tooth groove 302 for clamping the steel cable 1 of the fixed flexible support.

[0038] To enhance the strength and reduce the weight of the irregularly shaped fastener 3, the irregularly shaped fastener 3 is made of aluminum alloy and is formed by one-time stamping. Furthermore, the clamping part 301 is designed to be hollow in the middle and is provided with a first reinforcing rib plate 307, which divides the space into a first chamber 308 and a second chamber 309.

[0039] The lower insertion part 303 is inserted into the steel pipe 2 fixed to the ground. The insertion part 303 has a through hole 304 for accommodating the connecting bolt 4. The special-shaped fastener 3 and the steel pipe 2 are connected as a whole by the connecting bolt 4.

[0040] The middle part of the insertion part 303 is designed to be hollow and is provided with a second reinforcing rib plate 310, which divides the space into a third chamber 311 and a fourth chamber 312. The lower outer side of the insertion part 303 is formed with an arc-shaped guide part 313 to facilitate the smooth insertion of the insertion part 303 into the steel pipe 2; the lower inner side of the insertion part 303 is formed with a curved reinforcing part 314 to enhance the strength of the lower part of the insertion part 303.

[0041] There is an integrally formed stepped transition shoulder 305 between the clamping part 301 and the insertion part 303. The stepped transition shoulder 305 is used to support the clamping part 301 on the outside of the steel pipe 2.

[0042] Among them, the aforementioned irregular fasteners 3 are all treated with an oxide film for corrosion protection, and the oxide film thickness is at least 12um. To ensure connection strength and reliability, the thinnest wall thickness of the irregular fasteners 3 is at least 3mm.

[0043] The clamping part 301 has a through hole 306 for accommodating the locking bolt 5. The locking bolt 5 tightens the two irregularly shaped fasteners 3, causing the teeth of the clamping grooves 302 of the irregularly shaped fasteners 3 to firmly grip the steel cable 1, restricting the sliding of the steel cable 1 within the clamping grooves 302, thus completing the connection between the steel pipe 2 and the steel cable 1. The irregularly shaped fastener 3 has teeth within its grooves, with a tooth depth of at least 0.5 mm.

[0044] In step S2, the insertion part 303 of the irregular fastener 3 from step S1 is inserted into the steel pipe 2 and extended to the designated position. Then, the irregular fastener 3 and the steel pipe 2 are connected as a whole by the connecting bolt 4.

[0045] Step S3: Tighten the two irregular fasteners 3 with locking bolts 5 so that the teeth of the irregular fasteners 3 tightly bite the steel cable, restricting the sliding of the steel cable 1 in the tooth groove, and completing the connection between the steel pipe 2 and the steel cable 1.

[0046] This invention solves the problem of reliable connection between the steel pipes and cables of the stabilization system in flexible support systems, ensuring an effective connection between the stabilization system and the cables, and guaranteeing the safe operation of the power station. This invention utilizes the integrated function of irregularly shaped fasteners to reduce the difficulty of high-altitude construction, shorten the construction period, and reduce the construction cost of the power station. This invention provides anti-corrosion treatment to the connection nodes, improving their durability and ensuring the long-term operation of the photovoltaic power station.
