Description

Technical Field

[0001] This application relates to the field of rope anti-slip technology, and in particular to a rope anti-slip device. Background Technology

[0002] In related technologies, clamp structures are commonly used to fix ropes. Although clamp structures provide good radial restraint for the rope, they mainly rely on the friction between the rope and the clamp to limit rope slippage in the axial direction. This results in weak axial restraint and makes the rope prone to axial slippage, affecting the reliability of the rope fixation. Utility Model Content

[0003] The main objective of this application is to propose a rope anti-slip device and a photovoltaic system, which aims to improve the ability to limit the axial displacement of the rope, thereby ensuring the reliability of the rope's fixation.

[0004] To achieve the above objectives, the rope anti-slip device proposed in this application includes an installation component, on which at least one set of limiting components are provided; A set of the limiting members includes two rotating members, with a through groove formed between the two rotating members; or, a set of the limiting members includes one rotating member and one fixing member, with a through groove formed between the rotating member and the fixing member. The rotating member has an abutting portion for abutting the rope, the abutting portion having a first end A and a second end B distributed sequentially in a first direction; The distance between the rotation center O of the rotating component and the rope is d, the distance between the rotation center O of the rotating component and the first end A is D1, and the distance between the rotation center O of the rotating component and the second end B is D2, wherein at least one of D1 and D2 is greater than d.

[0005] In one embodiment, the rotating component satisfies: D1=D2>d.

[0006] In one embodiment, the rotating member satisfies: D1>D2≥d or D2>D1≥d.

[0007] In one embodiment, a set of limiting members includes two rotating members, both of which satisfy: D1>D2≥d.

[0008] In one embodiment, one of the rotating members satisfies: D1>D2≥d, and the other rotating member satisfies: D2>D1≥d.

[0009] In one embodiment, the rotating element is configured as a cam structure or a polygonal block.

[0010] In one embodiment, the abutting portion is provided with anti-slip texture.

[0011] In one embodiment, the abutting portion extends continuously in the first direction.

[0012] In one embodiment, the abutting portion has a groove between its two ends.

[0013] In one embodiment, the rotating member is mounted to the mounting member by fasteners.

[0014] In one embodiment, the mounting member includes a plate, and the limiting member is provided on at least one side of the plate.

[0015] In one embodiment, the mounting component includes at least two plates, with the limiting member sandwiched between the two plates.

[0016] This application also proposes a photovoltaic system, which includes: Support beam; The aforementioned rope anti-slip device, wherein the mounting component is fixedly installed on the support beam; A flexible support, comprising a rope threaded through the cable groove; and Photovoltaic modules are mounted on the flexible support.

[0017] In the technical solution of this application, the cable groove is used to accommodate the rope. The first direction corresponds to one of the axial directions of the rope. The rope in the cable groove will abut against the corresponding structures of the limiting member on both radial sides, thereby limiting the radial displacement of the rope. Based on this, by making at least one of D1 and D2 greater than d, the rope slippage can be reliably limited in at least one axial direction, thereby improving the ability to limit the axial displacement of the rope.

[0025] This application proposes a rope anti-slip device.

[0026] Please see Figures 1 to 3 In one embodiment of this application, the rope anti-slip device includes an installation member 100, and at least one set of limiting members 200 are provided on the installation member 100; A set of limiting members 200 includes two rotating members 220, with a wire groove 201 formed between the two rotating members 220; or, a set of limiting members 200 includes one rotating member 220 and one fixing member 210, with a wire groove 201 formed between the rotating member 220 and the fixing member 210. The rotating member 220 has an abutting portion 221 for abutting the rope 320, and the abutting portion 221 has a first end A and a second end B distributed sequentially in a first direction; The distance between the rotation center O of the rotating component 220 and the rope 320 is d, the distance between the rotation center O of the rotating component 220 and the first end A is D1, and the distance between the rotation center O of the rotating component 220 and the second end B is D2, at least one of D1 and D2 is greater than d.

[0027] In the technical solution of this application, the cable groove 201 is used to accommodate the rope 320. The first direction corresponds to one of the axial directions of the rope 320. The rope 320 in the cable groove 201 will abut against the corresponding structures of the limiting member 200 on both radial sides, thereby limiting the radial displacement of the rope 320. Specifically, it can be, as follows: Figure 2As shown, the cable groove 201 is formed between two rotating members 220, and the rope 320 abuts against different rotating members 220 on both radial sides. Alternatively, it can be as follows: Figure 1 As shown, the cable groove 201 is formed between a rotating member 220 and a fixed member 210. One side of the rope 320 abuts against the fixed member 210, and the other side abuts against the rotating member 220.

[0028] The rotating member 220 abuts against the rope 320 via the abutment portion 221. (See also...) Figure 3 The distance d between the rotation center O of the rotating member 220 and the rope 320 refers to the length of the perpendicular line from the rotation center O of the rotating member 220 to the rope 320, which is also the distance between the rotation center O and the foot of the perpendicular H. This distance d also corresponds to the shortest distance between the rotation center O of the rotating member 220 and the rope 320. For ease of description later, the portion of the abutment 221 located between the foot of the perpendicular H and the first end A is referred to as the first portion AH, and the portion of the abutment 221 located between the foot of the perpendicular H and the second end B is referred to as the second portion HB.

[0029] Please see Figure 3 When D1 is greater than d, the first part AH of the abutment 221 will gradually move away from the rotation center O from the position of the vertical foot H along the opposite direction of the first direction toward the first end A. At this time, if the rope 320 has a tendency to slide along the first direction, the rotating member 220 will have a tendency to rotate counterclockwise as shown in the figure, so that the first part AH abuts against the rope 320, increasing the force of the rotating member 220 on the rope 320. Even if the fixing member 210 is provided on the other side of the rope 320, the rotating member 220 can still press the rope 320 against the clamping member, so that the fixing member 210 passively increases the pressure on the rope 320. Of course, if the rope 320 is located between the two rotating members 220, both rotating members 220 can actively increase the pressure on the rope 320. Thus, the rope 320 will be subjected to opposite pressures on both radial sides, that is, the rope 320 can be clamped on both radial sides, thereby restricting the rope 320 from sliding along the first direction.

[0030] Please see Figure 3 When D2 is greater than d, the second part HB of the abutment 221 will gradually move away from the rotation center O from the position of the vertical foot H along the first direction toward the second end B. At this time, if the rope 320 has a tendency to slide in the opposite direction of the first direction, the rotating member 220 will have a tendency to rotate clockwise as shown in the figure, so that the second part HB abuts against the rope 320. Similarly, pressure in opposite directions can be applied to the rope 320 on both radial sides, so that the rope 320 can be clamped on both radial sides, thereby restricting the rope 320 from sliding in the opposite direction of the first direction.

[0031] Therefore, by ensuring that at least one of D1 and D2 is greater than d, slippage of the rope 320 can be reliably restricted in at least one axial direction, thereby improving the ability to limit the axial displacement of the rope 320. In practical applications, D1 or D2 can be designed to be greater than d, or both D1 and D2 can be greater than d, depending on the requirements.

[0032] The rotating member 220 can abut against the rope 320 through a structure not limited to the abutment portion 221. For example, it can abut against the rope 320 through a plane including the abutment portion 221.

[0033] In one implementation, please refer to Figure 3 The rotating member 220 satisfies: D1=D2>d. That is, the first end A and the second end B are symmetrically distributed on both sides of the vertical foot H, so that the rotating member 220 can provide considerable clamping capacity at the two end positions, and thus the limiting member 200 can provide considerable displacement restriction capacity in both directions of the axial direction of the rope 320, which is beneficial to improving the fixing reliability of the rope 320 in the cable groove 201.

[0034] In one implementation, please refer to Figures 4 to 7 The rotating component 220 satisfies either D1 > D2 ≥ d or D2 > D1 ≥ d. It can be understood that the side with the endpoint farther from the rotation center O has a stronger clamping capacity. If the distance between an endpoint and the rotation center O is equal to d, then the perpendicular H coincides with that endpoint, and the clamping capacity on that side is weaker. Therefore, based on the difference in the risk of slippage of the rope 320 in the two axial directions in actual application scenarios, different displacement limiting capabilities can be configured for the first end A and the second end B to avoid over-design and material waste.

[0035] In one implementation, please refer to Figure 4 and Figure 5 A set of limiting members 200 includes two rotating members 220, both of which satisfy: D1>D2≥d. Thus, at the first end A, the two rotating members 220 have a strong clamping capacity, and correspondingly, the set of limiting members 200 can also effectively limit the displacement of the rope 320 in one of the axial directions.

[0036] In one implementation, please refer to Figure 6 and Figure 7 One rotating component 220 satisfies: D1>D2≥d, and the other rotating component 220 satisfies: D2>D1≥d. In this way, the clamping capabilities provided by the two rotating components 220 at the same end position can complement each other, thereby helping to achieve a balance between saving materials and enhancing axial displacement restriction capability.

[0037] In one implementation, please refer to Figures 1 to 3 The abutting portion 221 extends continuously in the first direction. Thus, the abutting portion 221 abuts against the rope 230 through a continuous planar or near-planar structure, which helps to evenly distribute the contact stress between the abutting portion 221 and the rope 230, avoid local stress concentration, thereby reducing damage to the surface structure of both and improving the durability of the rope anti-slip device.

[0038] In one implementation, please refer to Figure 13 The abutment portion 221 has a groove 223 between its two ends. In this way, the abutment portion 221 can abut against the rope 230 at least through the first end A and the second end B, which is equivalent to reducing the contact area between the abutment portion 221 and the rope 230. When the rope 230 tends to slip axially, it can generate greater contact pressure and friction, thereby enhancing the ability to limit the axial displacement of the rope 230.

[0039] In one embodiment, the rotating member 220 is configured as a cam structure or a polygonal block shape. Specifically, except... Figure 3 and Figure 5 The shape shown can also be a circular or semi-circular shape with the rotation axis eccentric; please refer to [link to relevant documentation]. Figure 8 and Figure 9 The polygonal blocks can be triangles, quadrilaterals, pentagons, etc.

[0040] In one implementation, please refer to Figure 3 and Figure 4 The contact portion 221 is provided with anti-slip texture 222. The anti-slip texture 222 can significantly increase the coefficient of friction between the rotating part 220 and the rope 320. When the rotating part 220 presses against the rope 320, the frictional force increases accordingly, effectively suppressing the slight slippage of the rope 320 in the cable groove 201. Especially under vibration or alternating load conditions, it can further improve the stability and reliability of axial positioning. Specifically, the anti-slip texture 222 can be serrated, or it can be a frosted texture or an etched texture.

[0041] In one implementation, please refer to Figure 7 The rotating member 220 can have abutment portions 221 formed on different sides. In this way, the rotating member 220 can be rotated to different states to form a suitable wire groove 201. Furthermore, after the anti-slip texture 222 provided on one abutment portion 221 is worn, the other abutment portion 221 can be switched to engage with the rope 320, which can reduce the maintenance and replacement cost of the rotating member 220.

[0042] In one implementation, please refer to Figure 11 and Figure 12In the first direction, multiple sets of limiting members 200 are distributed. These multiple sets of limiting members 200 are arranged at intervals along the axial direction of the rope 320, enabling multi-point clamping of the rope 320. When the rope 320 slips under force, the multiple limiting points work together to disperse the force and provide resistance at each level, significantly enhancing the overall axial constraint capability, preventing local stress concentration, and improving the system's safety redundancy.

[0043] In one implementation, please refer to Figures 10 to 12 The rotating component 220 is mounted on the mounting component 100 via fasteners 310. It can be understood that the fasteners 310 also serve as the pivot of the rotating component 220. Using fasteners 310 facilitates the assembly, disassembly, and maintenance of the rotating component 220. Furthermore, the rotational damping of the rotating component 220 can be controlled by adjusting the preload of the fasteners 310, optimizing its response sensitivity and ensuring timely rotation and effective clamping under the slippage tendency of the rope 320, thereby improving the adjustability and adaptability of the device.

[0044] In one implementation, please refer to Figure 12 The mounting component 100 includes a plate 110, and a limiting member 200 is provided on at least one side of the plate 110. The plate 110 has a simple structure, is easy to process and manufacture, and has good structural strength. In addition, the limiting member 200 can be flexibly set on one or both sides of the plate 110 according to different installation spaces and rope 320 arrangement requirements.

[0045] In one implementation, please refer to Figure 10 and Figure 11 The mounting component 100 includes at least two plates 110, with a limiting member 200 sandwiched between the two plates 110. It is understood that the rope 320 will also be sandwiched between the two plates 110. Thus, the two plates 110 can protect the limiting member 200 and the rope 320, improving the installation stability of the limiting member 200 and the rope 320. In this embodiment, the same fastener 310 can simultaneously pass through both plates 110 and a rotating member 220 to save on components.

[0046] This application also proposes a photovoltaic system, which includes a rope anti-slip device. The specific structure of the rope anti-slip device is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0047] Specifically, please refer to Figure 10The photovoltaic system also includes a support beam 330, a flexible support structure, and photovoltaic modules. The mounting component 100 is fixedly installed on the support beam 330. The flexible support structure includes ropes 320, which pass through cable trays 201. The photovoltaic modules are installed on the flexible support structure. It is understood that during the construction of the photovoltaic system, or under environmental factors such as wind load, snow load, or temperature changes, the ropes 320 in the flexible support structure are prone to axial tension fluctuations, leading to a slippage tendency. This application utilizes a rope anti-slip device to reliably clamp the ropes 320, effectively suppressing their axial slippage, ensuring the stable tension of the flexible support structure, guaranteeing the installation stability of the photovoltaic modules, and thus ensuring the structural safety and power generation efficiency of the photovoltaic system during long-term operation.

[0048] The above are merely exemplary embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
