Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, and in particular to a flexible photovoltaic support cable angle adaptive end anchor device. Background Technology

[0002] Flexible photovoltaic (PV) support systems utilize prestressed cables (i.e., cables) tensioned between two supports, with PV panels fixed to the cables via clips. This allows them to span unfavorable terrains such as fishponds, valleys, and ravines, adapting to various landform features and becoming an important support technology direction for mountainous PV projects.

[0003] However, due to the complex topography and large slope variations in mountainous areas, the angles of the flexible photovoltaic support cables at the end anchor connections vary greatly as they are arranged along the slope. This results in the anchor plate and the cable not being completely perpendicular, leading to a decrease in the anchoring performance of the anchor ends, reduced reliability of the connection nodes, and potential safety hazards to the overall structure of the flexible support. Utility Model Content

[0004] This utility model aims to provide a flexible photovoltaic support cable angle adaptive end anchor device to solve the technical problem in the prior art where the angle of the flexible photovoltaic support cable at the end anchor connection varies greatly due to the complex topography and large slope changes in mountainous areas.

[0005] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0006] A flexible photovoltaic support cable angle adaptive end anchor device is provided for connecting the cable, comprising:

[0007] A column, which is set on the ground, has vertically arranged strip-shaped holes on both sides;

[0008] An anchor is provided on the column and is used to fix the cable. The cable passes through two slots in the column and is then fixedly connected to the anchor.

[0009] A rotating assembly is disposed on the side of the column near the anchor, and the anchor can rotate on the rotating assembly to adjust the angle of the cable;

[0010] The anchor can rotate on the rotating assembly so that the plane in which the anchor is located always remains perpendicular to the cable.

[0011] In some embodiments, the rotating assembly includes an arc-shaped support plate and an anchor plate;

[0012] The arc-shaped support plate is disposed on the side of the support column near the anchor.

[0013] The anchor plate is disposed on the anchor near the side of the arc-shaped support plate;

[0014] The anchor plate and the arc-shaped support plate are in close contact with each other, and the anchor plate can drive the anchor to rotate on the arc-shaped support plate to adapt to the angle of the cable.

[0015] In some embodiments, the anchor plate is concave on the side near the arc-shaped support plate to fit against the arc-shaped support plate.

[0016] In some embodiments, the length of the strip hole is greater than the length of the arc-shaped support plate to provide sufficient space for the cable to adjust its angle.

[0017] In some embodiments, two arc-shaped support plates are provided, and the two arc-shaped support plates are arranged opposite each other on both sides of the strip hole on the column, forming a limiting channel between the two arc-shaped support plates. The cable passes through the strip hole, the limiting channel and the anchor plate in sequence and is then connected to the anchor.

[0018] In some embodiments, the sides of the two arc-shaped support plates are in contact with the cable to limit the cable.

[0019] In some embodiments, the anchor plate has a through hole for the cable to pass through and connect to the anchor.

[0020] In some embodiments, two stiffening ribs are welded to the sides of each of the two arc-shaped support plates.

[0021] Compared with existing technologies, in the flexible photovoltaic support cable angle adaptive end anchor device provided in this embodiment, the rotating component ensures that the anchor plane is always perpendicular to the cable axis, so that the cable tension is evenly applied to the anchor plate, avoiding local stress concentration.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0031] The following is combined with Figures 1 to 4 The flexible photovoltaic support cable angle adaptive end anchor device 100 provided in this application will be described in detail through specific embodiments.

[0032] Please refer to the following: Figures 1 to 4 , Figure 1 This is a structural schematic diagram of the flexible photovoltaic support cable angle adaptive end anchor device provided by this utility model; Figure 2 This is a side view of the connecting rod of the flexible photovoltaic support cable angle adaptive end anchor device provided by this utility model; Figure 3 This is a top view of the connecting rod of the flexible photovoltaic support cable angle adaptive end anchor device provided by this utility model; Figure 4 This is a partial structural diagram of the connecting rod of the flexible photovoltaic bracket cable angle adaptive end anchor device provided by this utility model. One embodiment of the flexible photovoltaic bracket cable angle adaptive end anchor device 100 includes a column 10, an anchor 20, and a rotating assembly 30. The column 10 is set on the ground, and corresponding strip holes 11 are vertically opened on both sides of the column 10. The anchor 20 is set on the column 10 and is used to fix the cable 40. The cable 40 passes through the two strip holes 11 of the column 10 in sequence and is fixedly connected to the anchor 20. The rotating assembly 30 is set on the side of the column 10 near the anchor 20. The anchor 20 can rotate on the rotating assembly 30 to adjust the angle of the cable 40. The anchor 20 can rotate on the rotating assembly 30 so that the plane of the anchor 20 remains perpendicular to the cable 40.

[0033] The column 10 serves as the foundation support for the device, fixed to the ground via embedded parts or concrete pouring, and bears all loads transmitted by the cable 40 (including prestress, wind load, snow load, etc.). The column 10 provides an installation base for the anchor 20 and rotating assembly 30, ensuring the relative positional accuracy of each component. The slotted holes 11 on both sides provide a path for the cable 40 to pass through, while the position of the holes limits the horizontal and vertical offset of the cable 40, ensuring that the path of the cable 40 at the column 10 is controllable. The slotted holes 11 allow the cable 40 to be finely adjusted up and down or left and right within a certain range to adapt to the slope changes of mountainous terrain, avoid the cable 40 from being rigidly bent due to terrain undulations, and reduce stress concentration.

[0034] Anchor 20 secures the end of cable 40 through clamping and tensioning, ensuring effective transfer of prestress from cable 40 to column 10. Anchor 20 converts the tension on cable 40 into pressure or shear force between anchor 20 and column 10, which is then transmitted to column 10 via rotating component 30. Anchor 20, connected to rotating component 30, automatically adjusts its orientation to maintain perpendicularity to the cable 40 axis as the cable 40 angle changes. The rotatable anchor 20 eliminates angular deviations between cable 40 and anchor plate 32 caused by terrain slope (e.g., angle differences exceeding 10° in mountainous terrain), preventing anchor 20 failure or cable 40 fatigue fracture due to eccentric stress.

[0035] The rotating assembly 30 ensures that the plane of the anchor 20 is always perpendicular to the axis of the cable 40, allowing the tension of the cable 40 to be evenly applied to the anchor plate 32, avoiding localized stress concentration. This design eliminates the need for manual on-site adjustment of the anchor 20 angle, and through structural adaptability to complex terrain, significantly simplifies the construction difficulty of mountain photovoltaic projects and improves installation efficiency. This solves the technical problem of "anchor plate 32 not being perpendicular to cable 40," enabling it to adapt to slope variations in complex terrains such as mountains, valleys, and fishponds. The rotating assembly 30 ensures that the plane of the anchor 20 is always perpendicular to the axis of the cable 40, allowing the tension of the cable 40 to be evenly applied to the anchor plate 32, avoiding localized stress concentration.

[0036] In some embodiments, the rotating assembly 30 includes an arc-shaped support plate 31 and an anchor plate 32; the arc-shaped support plate 31 is disposed on the side of the support column near the anchor 20; the anchor plate 32 is disposed on the anchor 20 near the side of the arc-shaped support plate 31; wherein the anchor plate 32 and the arc-shaped support plate 31 are in contact with each other, and the anchor plate 32 can drive the anchor 20 to rotate on the arc-shaped support plate 31 to adapt to the angle of the cable 40.

[0037] The rotational freedom of the arc-shaped support plate 31 complements the guiding function of the strip hole 11 in the column 10. The strip hole 11 allows for fine-tuning of the cable 40 vertically, while the arc-shaped surface allows for angular rotation, together achieving dual self-adaptation of the cable 40's "position + angle". When the tension of the cable 40 acts on the anchor plate 32 along the axis, it generates a component force that causes the anchor plate 32 to rotate in contact with the arc-shaped surface. This component force balances the normal reaction force of the arc-shaped surface, forcing the anchor plate 32 to automatically adjust to a vertical state.

[0038] In addition, a limiting flange (5-10mm high) can be provided on the edge of the arc-shaped support plate 31 to prevent the anchor plate 32 from rotating excessively and deviating from the track. At the same time, a gap of 1-2mm is reserved between the limiting flange and the anchor plate 32 to not affect the normal degree of freedom of rotation.

[0039] In some embodiments, the anchor plate 32 is concave on the side near the arc-shaped support plate 31 to fit against the arc-shaped support plate 31. This allows the anchor plate 32 and the arc-shaped support plate 31 to fit together. When the anchor plate 32 is subjected to a force from the cable 40, it can rotate on the arc-shaped support plate 31, thereby causing the anchor 20 to rotate, so that the plane of the anchor 20 is always perpendicular to the axis of the cable 40.

[0040] In some embodiments, the length of the strip hole 11 is greater than the length of the arc-shaped support plate 31 to provide sufficient space for the cable 40 to adjust its angle. If the length of the strip hole 11 is insufficient, the cable 40 will bend due to the limitation of the hole wall when it rotates. When the length of the strip hole 11 is sufficient, the cable 40 can slide freely along the length of the hole, avoiding fatigue fracture of the steel strand due to repeated bending.

[0041] In some embodiments, two arc-shaped support plates 31 are provided, and the two arc-shaped support plates 31 are arranged opposite each other on both sides of the strip hole 11 on the column 10. A limiting channel is formed between the two arc-shaped support plates 31. The cable 40 passes through the strip hole 11, the limiting channel and the anchor plate 32 in sequence and is then connected to the anchor 20.

[0042] In some embodiments, the sides of the two arc-shaped support plates 31 are in contact with the cable 40 to limit the cable 40. When the cable 40 enters the limiting channel, the two arc-shaped support plates 31 can restrict the cable 40 from shifting left or right.

[0043] In some embodiments, the anchor plate 32 has a through hole for the cable 40 to pass through and connect to the anchor 20.

[0044] In some embodiments, two stiffening ribs 33 are welded to the sides of each of the two arc-shaped support plates 31. The stiffening ribs 33 are used to support the arc-shaped support plates 31 to ensure the out-of-plane stability of the arc-shaped support plates 31 under the pressure F transmitted by the anchor plate 32.
