Abstract

Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, specifically a flexible cable structure for a double-row linkage tracking flexible photovoltaic support system. Background Technology

[0002] Currently, flexible photovoltaic supports, as an emerging type of fixed support, overcome the shortcomings of traditional supports such as small span, large steel consumption, and weak adaptability to terrain by relying on the large span support structure formed by tensioned prestressed cables. They are widely used in complex terrains such as mountains, sewage treatment plants, and fish ponds.

[0003] Existing rigid tracking supports suffer from problems such as bulky systems, high energy consumption, and complex maintenance, making them incompatible with the efficient layout characteristics of flexible supports. They are unable to balance large-span layout, efficient power generation, and structural stability in complex terrain. Utility Model Content

[0004] The purpose of this invention is to provide a flexible cable structure for a dual-row linkage tracking flexible photovoltaic support system, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible cable structure for a double-row linkage tracking flexible photovoltaic support system, including a support frame mechanism. The support frame mechanism includes a top frame disposed on the top, a crossbeam disposed parallel below the top frame, and the two ends of the top frame are fixed to the crossbeam by diagonal connecting ribs. The crossbeam and the top frame are connected and fixed by vertical reinforcing ribs.

[0006] Furthermore, the top frame, crossbeam, and connecting ribs form an inverted triangular pyramid structure, and adjacent triangular structures are connected and fixed by oblique reinforcing ribs.

[0007] Furthermore, a cable anchoring mechanism is installed on the top frame and the crossbeam. The cable anchoring mechanism includes a base bolted to the top frame and the crossbeam, and a U-shaped clamp with an open end is fixedly installed on the base.

[0008] Furthermore, the cable anchoring mechanism also includes an external thread formed on the outer wall of the U-shaped clamp, and a locking nut is tightened on the outer thread of the external thread.

[0009] Furthermore, the cable anchoring mechanism also includes a pressure block embedded inside the U-shaped clamp recess, and the bottom arc surface of the pressure block is provided with a serrated pattern.

[0010] Furthermore, adjacent support frame mechanisms are connected by cable bodies through cable anchoring mechanisms, and photovoltaic modules are mounted on the cable bodies. The two ends of the cable bodies are anchored to the truss beams through anchors.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In use, the cable body and the truss beam are reliably connected by anchors. The cable bodies are connected by a spatial three-dimensional support frame mechanism. The top frame, crossbeam and connecting ribs in the support frame mechanism form an inverted triangular pyramid structure. With the diagonal reinforcing ribs and flexible cable layout, it can effectively resist lateral forces and distribute loads, forming a stable spatial force system. This application innovatively realizes the arrangement of double-row photovoltaic modules along the array direction. This layout significantly increases the power generation capacity per unit area without increasing the structural weight too much. The rigid connection design of the end bracket combined with the flexible cable layout not only ensures the structural force transmission stability, but also realizes the arrangement of photovoltaic modules with large span and high adaptability.

[0013] 2. In use, when the spatial three-dimensional support frame mechanism is installed between the cable bodies and the double-row photovoltaic modules are installed and fixed in sequence, the cable body is directly inserted into the U-shaped clamp opening and then radially placed into the pressure block. The outer wall thread of the U-shaped clamp and the locking nut cooperate to form a two-way constraint. The pressure block converts the radial pressure into a circumferential clamping force on the cable body, which can effectively suppress the slippage of the cable body. It eliminates the cable pre-alignment step of traditional anchors and is especially suitable for high-altitude or confined space operations. The detachable structure facilitates the replacement of the cable body or the adjustment of the pre-tightening force in the later stage, avoiding the irreversible defects of welded anchors.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 3As shown, a flexible cable structure for a double-row linkage tracking flexible photovoltaic support system includes a support frame mechanism 1. The support frame mechanism 1 includes a top frame 101 disposed on the top, and a crossbeam 102 is disposed parallel below the top frame 101. The two ends of the top frame 101 are fixed to the crossbeam 102 by diagonal connecting ribs 103. The crossbeam 102 and the top frame 101 are connected and fixed by vertical reinforcing ribs 104. The top frame 101, the crossbeam 102 and the connecting ribs 103 form an inverted triangular pyramid structure, and adjacent triangular structures are connected and fixed by diagonal reinforcing ribs 104.

[0020] The specific operation is as follows: The cable body 3 and the truss beam 5 are reliably connected by anchors. The cable bodies 3 are connected by a spatial three-dimensional support frame mechanism 1. The top frame 101, the crossbeam 102 and the connecting rib 103 in the support frame mechanism 1 form an inverted triangular pyramid structure. With the diagonal reinforcing rib 104 and the flexible cable layout, it can effectively resist lateral forces and distribute loads, forming a stable spatial force system. This application innovatively realizes the arrangement of double-row photovoltaic modules 4 along the array direction. This layout significantly increases the power generation capacity per unit area without increasing the structural weight too much. The rigid connection design of the end bracket combined with the flexible cable layout not only ensures the structural force transmission stability, but also realizes the arrangement of photovoltaic modules 4 with large span and high adaptability.

[0021] like Figures 1 to 3 As shown, a cable anchoring mechanism 2 is installed on the top frame 101 and the crossbeam 102. The cable anchoring mechanism 2 includes a base 201 bolted to the top frame 101 and the crossbeam 102, and a U-shaped clamp 202 with an end opening is fixedly installed on the base 201. The cable anchoring mechanism 2 also includes an external thread 203 opened on the outer wall of the U-shaped clamp 202, and a locking nut 204 is tightened on the external thread of the external thread 203. The cable anchoring mechanism 2 also includes a pressure block 205 embedded in the recess of the U-shaped clamp 202, and the bottom arc surface of the pressure block 205 is provided with a serrated pattern. The adjacent support frame mechanisms 1 are connected by a cable body 3 through the cable anchoring mechanism 2, and a photovoltaic module 4 is mounted on the cable body 3. The two ends of the cable body 3 are anchored to the truss beam 5 through anchors.

[0022] The specific operation is as follows: During the process of installing the spatial three-dimensional support frame mechanism 1 between the cable bodies 3 and installing and fixing the double-row photovoltaic modules 4 in sequence, the cable body 3 is directly inserted through the opening of the U-shaped clamp 202 and then radially placed into the pressure block 205. The outer wall thread of the U-shaped clamp 202 cooperates with the locking nut 204 to form a two-way constraint. The pressure block 205 converts the radial pressure into a circumferential clamping force on the cable body 3, which can effectively suppress the slippage of the cable body 3, eliminate the cable pre-alignment step of traditional anchors, and is especially suitable for high-altitude or confined space operations. The detachable structure facilitates the replacement of the cable body 3 or the adjustment of the pre-tightening force in the later stage, avoiding the irreversible defects of welded anchors.

[0023] Working principle: The cable body 3 is reliably connected to the truss beam 5 through anchors. The cable bodies 3 are connected by a spatial three-dimensional support frame mechanism 1. The top frame 101, crossbeam 102 and connecting rib 103 in the support frame mechanism 1 form an inverted triangular pyramid structure. With the help of the diagonal reinforcing rib 104 and the flexible cable layout, it can effectively resist lateral forces and distribute loads, forming a stable spatial force system. This application innovatively realizes the arrangement of double rows of photovoltaic modules 4 along the array direction. This layout significantly increases the power generation capacity per unit area without increasing the structural weight too much. The rigid connection design of the end support combined with the flexible cable layout ensures the structural force transmission stability and realizes large span. The photovoltaic module 4 arrangement is highly adaptable. During the process of installing the spatial three-dimensional support frame mechanism 1 between the cable bodies 3 and installing and fixing the double rows of photovoltaic modules 4 in sequence, the cable body 3 is directly inserted through the opening of the U-shaped clamp 202 and then radially placed into the pressure block 205. The outer wall thread of the U-shaped clamp 202 cooperates with the locking nut 204 to form a two-way constraint. The pressure block 205 converts the radial pressure into a circumferential clamping force on the cable body 3, which can effectively suppress the slippage of the cable body 3. It eliminates the cable insertion and pre-alignment steps of traditional anchors, and is especially suitable for high-altitude or confined space operations. The detachable structure facilitates the replacement of the cable body 3 or the adjustment of the pre-tightening force in the later stage, avoiding the irreversible defects of welded anchors.
