Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable technology, specifically an adjustable tension photovoltaic load-bearing cable assembly. Background Technology

[0002] In recent years, flexible photovoltaic (PV) supports have been increasingly used in complex terrains and special scenarios due to their structural characteristics of "large span, high clearance, and long spacing". They utilize cables as the main load-bearing structure and consist of columns, trusses, cables, and ground anchors, offering excellent adaptability and cost-effectiveness.

[0003] Currently, most common flexible support structures employ a split cable structure. This involves placing a load-bearing cable between two trusses, and additional diagonal cables between the trusses and ground anchors to balance horizontal forces. This structure requires multiple connection points on each truss and corresponding connection structures on the ground anchors, totaling six anchoring points to secure the entire cable system. This not only increases the number of connection structures but also raises installation difficulty and construction costs. Furthermore, it makes adjusting the cable tension inconvenient. Therefore, an adjustable tension photovoltaic load-bearing cable assembly is proposed to address these issues. Utility Model Content

[0004] This invention provides an adjustable tension photovoltaic load-bearing cable assembly, which realizes the cable system through a single load-bearing cable, solving the problems of high installation difficulty and construction cost, as well as the inconvenience of adjusting the tension of the cable.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable tension photovoltaic load-bearing cable assembly, comprising:

[0006] The truss consists of two trusses, each consisting of multiple columns with supporting beams at the top and a central crossbeam between the columns.

[0007] The load-bearing cable assembly comprises multiple components, including two ground anchor structures located on opposite sides of two trusses. Each of the two trusses has a lockable cable saddle at the top of its support beam. The two ground anchor structures are connected by a load-bearing cable passing through the lockable cable saddle. A tension adjustment assembly connected to the load-bearing cable is installed on the middle crossbeam of any one or two trusses.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the lockable saddle includes a U-shaped seat, with a mounting base at the bottom of the U-shaped seat. Both sides of the U-shaped seat have lifting grooves, in which lifting guide wheel assemblies are mounted and lowered. A support spring is also provided in the lifting groove below the lifting guide wheel assembly. The tops of both sides of the U-shaped seat are threaded with pressing bolts. A receiving part is also provided on the inner side of the U-shaped seat. A locking part higher than the lifting guide wheel assembly is provided. The receiving part and the locking part can clamp the load-bearing cable within them.

[0010] When the lifting guide wheel assembly is raised, its contact point with the load-bearing cable is higher than the receiving part.

[0011] Furthermore, the lifting guide wheel assembly includes two lifting blocks that are slidably disposed in two lifting slots respectively. The side of the lifting block is provided with a groove that slides with the side arm of the lifting slot. A wheel is rotatably disposed between the two lifting blocks, and a support spring is disposed at the bottom of the lifting block.

[0012] Furthermore, the receiving part includes a vertical plate disposed inside the U-shaped seat, a receiving platform disposed at the bottom of the vertical plate, and a lower arc-shaped groove disposed on the receiving platform.

[0013] Furthermore, the locking part includes two support plates symmetrically arranged on the top of the lifting block, and a locking plate located above the receiving platform is provided between the ends of the support plates. The bottom of the locking plate is provided with an upper arc groove opposite to the lower arc groove.

[0014] Furthermore, both the lower arc-shaped groove and the upper arc-shaped groove are one-third the length of the load-bearing cable.

[0015] Furthermore, the tension adjustment assembly includes a hinged seat mounted on the middle crossbeam, a cable telescopic rod hinged to the hinged seat, and a pulling element fitted onto the telescopic end of the cable telescopic rod.

[0016] Furthermore, the pulling component includes a U-shaped assembly, in which a sliding wheel is rotatably provided for contacting the load-bearing cable. The ends of the two side arms of the U-shaped assembly are provided with outwardly extending docking plates. The telescopic end of the cable telescopic rod is provided with a connecting plate that matches the docking plate. The docking plate and the connecting plate are fixed together by bolts and nuts.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. This adjustable tension photovoltaic load-bearing cable assembly, through the setting of two trusses and the adjustable load-bearing cable assembly, enables a single load-bearing cable to form a stable support structure between the two trusses. Through the cooperation of the ground anchor structure and the lockable cable saddle, a reliable cable-stayed system is constructed, thereby effectively improving the stability and load-bearing capacity of the overall structure. At the same time, tension adjustment components are set on the crossbeams in the trusses, which allows the load-bearing cable to be easily tensioned during installation, ensuring that it maintains a good stress state under different working conditions, thus improving the adaptability and safety of the photovoltaic support system.

[0019] 2. This adjustable tension photovoltaic load-bearing cable assembly, through a lockable saddle structure with lifting guide wheel assembly, not only reduces frictional resistance during the movement of the load-bearing cable when adjusting tension, improving adjustment efficiency and ease of operation, but also achieves a firm clamping of the load-bearing cable through the locking part and the receiving part after adjustment, enhancing the reliability of the connection. This design simplifies the complex anchoring arrangement in traditional cable structures, reduces the number of connection points and construction difficulty, thereby reducing the overall manufacturing and installation costs.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figure 1-9 As shown, an adjustable tension photovoltaic load-bearing cable assembly in this embodiment includes: a truss 1 and a load-bearing cable assembly 2. The number of trusses 1 is two, specifically including multiple columns 101. A support beam 103 is provided on the top of the column 101, and a middle crossbeam 102 is provided between the columns 101.

[0033] The number of load-bearing cable assemblies 2 is multiple and can be adjusted according to the needs of use. Specifically, it includes two ground anchor structures 22 set on the opposite sides of the two trusses 1. The top of the support beam 103 of the two trusses 1 is provided with a lockable cable saddle 20. The two ground anchor structures 22 are connected by a load-bearing cable 23 passing through the lockable cable saddle 20. One or two of the trusses 1 have a tension adjustment assembly 21 connected to the load-bearing cable 23 on the middle crossbeam 102.

[0034] With this design, a support structure can be formed between the two trusses 1 by a load-bearing cable 23. At the same time, the load-bearing cable 23 is fixed by the lockable cable saddle 20, forming a diagonal tension structure between it and the ground anchor structure 22. In addition, the tension adjustment component 21 set on the middle crossbeam 102 can adjust the tension of the load-bearing cable 23 before the lockable cable saddle 20 locks the load-bearing cable 23.

[0035] It should be noted that the ground anchor structure 22 and the connection structure between the load-bearing cable 23 and the ground anchor structure 22 are existing technologies in the field, and therefore will not be described in detail here.

[0036] Furthermore, the lockable saddle 20 includes a U-shaped seat 201, with a mounting base 208 at the bottom of the U-shaped seat 201. Each of the two side arms of the U-shaped seat 201 has a lifting groove 202, in which a lifting guide wheel assembly 203 is vertically mounted. A support spring 204 is also located below the lifting guide wheel assembly 203 within the lifting groove 202. A pressing bolt 205 is threaded onto the top of each of the two side arms of the U-shaped seat 201. The height of the lifting guide wheel assembly 203 can be adjusted through the cooperation between the support spring 204 and the pressing bolt 205. A receiving part 206 is also provided on the inner side of the U-shaped seat 201. A locking part 207, higher than the lifting guide wheel assembly 203, is provided on the lifting guide wheel assembly 203. The receiving part 206 and the locking part 207 can clamp the load-bearing cable 23 within them.

[0037] It should be noted that when the lifting guide wheel assembly 203 is raised, its contact position with the load-bearing cable 23 is higher than that of the receiving part 206.

[0038] This design allows the lifting guide wheel assembly 203 to be raised to support the load-bearing cable 23 when adjusting its tension, reducing friction during adjustment and improving ease of adjustment. After adjustment, the lifting guide wheel assembly 203 is lowered so that the load-bearing cable 23 falls onto the receiving part 206, and the locking part 207 and the receiving part 206 form a clamping and fixing structure for the load-bearing cable 23.

[0039] In a preferred embodiment, the lifting guide wheel assembly 203 includes two lifting blocks 2030 that are slidably disposed in two lifting slots 202 respectively. The side of the lifting block 2030 is provided with a groove 2031 that slides with the side arm of the lifting slot 202, so that the lifting block 2030 can slide up and down while preventing it from sliding left and right. A wheel 2032 is rotatably disposed between the two lifting blocks 2030. The wheel 2032 is rotatably disposed between the two lifting blocks 2030 through a bearing, and the wheel 2032 is a concave wheel, which facilitates the embedding of the load-bearing cable 23 into the groove. The support spring 204 is disposed at the bottom of the lifting block 2030.

[0040] In a preferred embodiment, the receiving part 206 includes a vertical plate 2061 disposed inside the U-shaped seat 201, a receiving platform 2062 disposed at the bottom of the vertical plate 2061, and a lower arc-shaped groove 2063 disposed on the receiving platform 2062.

[0041] In addition, the locking part 207 includes two support plates 2070 symmetrically arranged on the top of the lifting block 2030. It should be noted that the position of the support plates 2070 does not affect the normal lifting and lowering of the lifting block 2030. A locking plate 2071 is provided between the ends of the support plates 2070, located above the receiving platform 2062. The bottom of the locking plate 2071 is provided with an upper arc groove 2072 opposite to the lower arc groove 2063.

[0042] In addition, both the lower arc-shaped groove 2063 and the upper arc-shaped groove 2072 are one-third of the load-bearing cable 23, which facilitates the clamping of the load-bearing cable 23.

[0043] This design allows the locking part 207 to rise and fall along with the lifting guide wheel assembly 203. Thus, when the lifting guide wheel assembly 203 rises, it releases its clamping engagement with the receiving part 206. When the lifting guide wheel assembly 203 descends, it clamps the load-bearing cable 23 with the receiving part 206.

[0044] In a preferred embodiment, the tension adjustment assembly 21 includes a hinge seat 210 disposed on the middle crossbeam 102, and a cable telescopic rod 211 is hingedly disposed on the hinge seat 210. In this embodiment, the cable telescopic rod 211 is a screw-type electric telescopic cylinder, and a pulling member fitted on the load-bearing cable 23 is installed on the telescopic end of the cable telescopic rod 211.

[0045] With this design, the tension of the load-bearing cable 23 can be adjusted by extending and retracting the cable telescopic rod 211 in conjunction with the pulling component.

[0046] Furthermore, the pulling component includes a U-shaped assembly 212, which facilitates the fitting of the load-bearing cable 23. The U-shaped assembly 212 is rotatably provided with a sliding wheel 213 for contacting the load-bearing cable 23. The sliding wheel 213 is rotatably mounted in the U-shaped assembly 212 via a bearing, and the sliding wheel 213 is a concave wheel, thereby reducing the frictional force in contact with the load-bearing cable 23. The ends of the two side arms of the U-shaped assembly 212 are provided with outwardly extending docking plates 214. The telescopic end of the cable telescopic rod 211 is provided with a connecting plate 215 that matches the docking plate 214. The docking plate 214 and the connecting plate 215 are fixed together by bolts and nuts 216.

[0047] This design facilitates the installation of the tension adjustment component 21 after the load-bearing cable 23 is installed, by installing the U-shaped kit 212 on the telescopic end of the cable telescopic rod 211, and at the same time, the tension of the load-bearing cable 23 can be adjusted by telescopically extending and retracting the cable telescopic rod 211.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
