[0002] Currently, there is no specific device for tensioning and fixing the module cables to the support structure during the construction of flexible photovoltaic systems in mountainous areas. Existing technologies typically use U-bolts and clamps to secure the module cables to the support components. During tensioning, the module cables need to pass through the U-bolts and clamps. However, during tensioning, the module cables experience sliding friction with the clamps and support structure, leading to damage to the anti-corrosion protective layer of both the module cables and the support structure.

[0057] Furthermore, the support plate 81 is provided with an eccentric shaft hole 811, an eccentric shaft hole 812, an adjusting plate screw hole 813, an anti-rotation block rotation shaft hole 814, and an anti-rotation shaft hole 815. The eccentric shaft holes 811 and 812 need to be concentrically arranged, the adjusting plate screw holes 813 need to be evenly distributed along the circumferential direction, the anti-rotation block rotation shaft hole 814 is a smooth hole, and the anti-rotation shaft hole 815 is a threaded hole.

[0058] The following explains the combination relationship of each part:

[0059] In this embodiment, the roller 2 is connected to the eccentric shaft 1 via the bearing 3 to form a roller assembly;

[0060] The eccentric shaft 1 is connected to the roller support structure 8 through the eccentric shaft hole 811 and the eccentric shaft hole 812;

[0061] The adjusting plate 4 is connected to the eccentric shaft 1 and then connected to the roller support structure 8 by screws 11;

[0062] The anti-rotation block 5 is connected to the roller support structure 8 via the anti-rotation block rotation shaft 6, and both ends of the anti-rotation block rotation shaft 6 are fixed by cotter pins 10; the anti-rotation shaft 7 is installed on the roller support structure 8 through the anti-rotation shaft hole 815, and the tapered structure 71 of the anti-rotation shaft 7 abuts against the side of the short toe 51 of the anti-rotation block 5, and the long toe 52 of the anti-rotation block presses against the bracket structure 12; the main function of the anti-rotation block 5 is to press against the bracket structure 12, and the main function of the anti-rotation shaft 7 is to prevent the anti-rotation block 5 from rotating;

[0063] The bracket structure 12 is disposed in the support plate groove 816. Two sets of roller assemblies are mounted on the upper and lower parts of the support plate 81. Each set of roller assemblies includes two roller assemblies, which are located at the same height. The eccentric shafts 1 in the two sets of roller assemblies are installed in opposite directions. For example, the square boss 011 of the eccentric shaft 1 of the upper set of roller assemblies is located on the left support plate 81, and the square boss 101 of the eccentric shaft 1 of the lower set of roller assemblies is located on the right support plate 81; or the square boss 101 of the eccentric shaft 1 of the upper set of roller assemblies is located on the right support plate 81, and the square boss 101 of the eccentric shaft 1 of the lower set of roller assemblies is located on the left support plate 81.

[0064] Furthermore, in this embodiment, two anti-rotation blocks 5 are provided and installed on the same side of the roller support structure 8; the roller 2 has an arc-shaped groove, and the roller 2 grooves on both sides of the roller support structure are on the same straight line, and the component cable 9 passes through the roller groove 21 in the two sets of roller assemblies in sequence.

[0065] Furthermore, the roller section 103 of the eccentric shaft 1 is connected to the inner ring of the bearing 3, and the outer ring of the bearing 3 is connected to the roller 2.

[0066] Furthermore, the thickness of the square boss 103 of the eccentric shaft 1 should be greater than the thickness of the adjusting plate 4.

[0067] Furthermore, the specific installation method of the above-mentioned component cable tensioning and fixing device for mountain flexible photovoltaic support is as follows:

[0068] The roller support structure 8 is installed onto the bracket structure 12 via the support plate groove 816, and the anti-rotation block 5 is pressed against the anti-rotation shaft 7, causing the anti-rotation block 5 to press against the bracket structure 12. The component cable 9 passes through the roller 2, and the gap between the rollers 2 is adjusted by the eccentric shaft 1. When the component cable 9 is tensioned, a gap is maintained between the roller 2 and the component cable 9. When the component cable 9 is fixedly installed, the eccentric shaft 1 is adjusted to make the component cable 9 and the bracket structure 12 in close contact.

[0069] Furthermore, when the component cable 9 is in a tensioned state, it is necessary to adjust the eccentric shaft 1 in the two sets of roller assemblies to ensure that the component cable 9 does not contact the support structure 12. The specific adjustment method is as follows:

[0070] Use a tool to turn the square boss 103 of the eccentric shaft 1 to adjust the gap between the component cable 9 and the bracket structure 12. When the component cable 9 and the bracket structure 12 are not in contact, connect the elongated hole 42 of the adjusting plate 4 and the adjusting plate screw hole 813 of the support plate 81 through the screw 11, tighten the screw 11, and fix the adjusting plate 4 and the support plate 81.

[0071] Furthermore, when the component cable 9 is in a fixed installation state, the eccentric shaft 1 needs to be adjusted to make the component cable 9 in close contact with the bracket structure 12;

[0072] Use a tool to turn the square boss 103 of the eccentric shaft 1 to adjust the gap between the component cable 9 and the bracket structure 12. After the component cable 9 and the bracket structure 12 are in close contact, connect the elongated hole 42 of the adjusting plate 4 and the adjusting plate screw hole 813 of the support plate 81 through the screw 11, tighten the screw 11, and fix the adjusting plate 4 and the support plate 81.

[0073] This utility model discloses a component cable tensioning and fixing device for flexible photovoltaic supports in mountainous areas, which has the advantages of simple design, strong practicality, and low manufacturing cost. This device effectively solves the problem of damage to the anti-corrosion protective layer between the component cable and the support structure during the tensioning process. Furthermore, after the component cable is tensioned, the adjusting roller mechanism ensures that the component cable makes tight contact with the support structure through compression, facilitating the fixing of the component cable to the support structure, simplifying construction, and also improving the service life of the flexible support.

[0074] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
