[0034] In photovoltaic power generation systems with corrugated steel roofs, the proper laying of photovoltaic cables is a crucial step in ensuring the safe and stable operation of the system. Photovoltaic cables need to connect from the photovoltaic modules to inverters, combiner boxes, and other equipment, typically requiring long-distance laying along the roof. Due to the unique corrugated structure of the corrugated steel roof surface, fixing and supporting the cables presents numerous technical challenges.

[0035] Currently, photovoltaic cables on corrugated steel roofs are often installed using methods such as drilling or adhesive fixing. These methods can easily damage the integrity of the corrugated steel roof, causing roof leaks. Drilling will create holes in the corrugated steel roof, compromising its waterproof performance; adhesive fixing is prone to aging and failure under temperature changes and ultraviolet radiation, leading to cable detachment.

[0036] Reference Figures 1 to 6 This application provides a photovoltaic cable laying device for a color steel tile roof, including clamps 100, crossbeams 200, and cable trays 300. Multiple clamps 100 are installed on the corrugated surface of the color steel tile, with each clamp 100 spaced apart along the length of the corrugated surface. The clamps 100 on adjacent corrugated surfaces are aligned with each other, thus forming an orderly array of clamps 100 on the color steel tile.

[0037] The clamp 100 includes a detachably connected first clamping member 110 and a second clamping member 120, which facilitates later maintenance and repair. When it is necessary to adjust or replace the clamp 100, it can be easily disassembled and reinstalled. The lower part of the first clamping member 110 is the first clamping part 111, and the lower part of the second clamping member 120 is the second clamping part 121. The two work together to clamp the corrugated color steel sheet.

[0038] Reference Figure 5 In the first embodiment, the first clamping part 111 is a straight plate structure, and the second clamping part 121 is an arc-shaped structure adapted to one side of the corrugated corrugated steel sheet. The straight plate structure of the first clamping part 111 fits against one side surface of the corrugated corrugated steel sheet, and achieves stable clamping through cooperation with the second clamping part 121. The inner side of the first clamping part 111 is provided with multiple horizontally extending serrations. These serrations can form a small mechanical engagement with the surface of the corrugated corrugated steel sheet when clamping, which significantly improves the anti-slip capability of the clamp 100 and ensures that the clamp 100 can still maintain a stable fixed state under the action of external forces such as wind load and snow load. The second clamping part 121 is an arc-shaped structure adapted to one side of the corrugated corrugated corrugated steel sheet. This arc-shaped design can perfectly fit the arc surface of one side of the corrugated corrugated corrugated steel sheet.

[0039] Reference Figure 6 In the second embodiment, the first clamping part 111 is an arc-shaped structure adapted to the corrugated side of the corrugated steel sheet. This design can better fit the arc-shaped contour of the corrugated steel sheet, increase the contact area, and improve the stability and reliability of clamping. The arc-shaped first clamping part 111 can form a more uniform stress distribution with the corrugated steel sheet during clamping, avoiding deformation or damage to the corrugated steel sheet that may be caused by localized stress concentration. This arc-shaped adaptation design is particularly suitable for applications requiring high clamping stability, such as cable laying in windy areas or under heavy load conditions.

[0040] To further enhance the stability and load-bearing capacity of the clamp 100, the bottom of the first clamping member 110 is horizontally bent to form a first support base 113, and the bottom of the second clamping member 120 is also horizontally bent to form a second support base 123. The first support base 113 and the second support base 123 increase the contact area between the clamp 100 and the color steel tile, providing additional support and stability. Especially when subjected to large lateral forces, the first support base 113 and the second support base 123 can effectively distribute the load and prevent the clamp 100 from overturning or slipping.

[0041] The first clamping member 110 has a slot 112 on its side, and the second clamping member 120 has a locking block 122. The locking block 122 cooperates with the slot 112 to achieve a quick connection. This snap-fit ​​connection method is simple to operate, has high installation efficiency, and has good connection reliability. The slot 112 is located below the support platform 114, extends horizontally along the width direction of the first clamping member 110 and passes through both sides of the first clamping member 110. Correspondingly, the locking block 122 is located on the top of the second clamping member 120, extends horizontally along the width direction of the second clamping member 120 to be flush with both sides of the second clamping member 120, ensuring a complete match and reliable connection between the locking block 122 and the slot 112, and improving the docking accuracy of the first clamping member 110 and the second clamping member 120.

[0042] In one specific embodiment, the slot 112 adopts a circular slot structure, and the locking block 122 adopts a cylindrical structure. This circular matching design allows the locking block 122 to be smoothly inserted into the slot 112 during assembly.

[0043] A support platform 114 is provided on the top of the first clamping member 110. The support platform 114 not only provides a stable installation foundation for the crossbeam 200, but more importantly, it transforms the clamp 100 from a simple fixing component into an important node of the load-bearing system. Through the support platform 114, the clamp 100 can effectively transfer the load from the crossbeam 200, the cable tray 300, and the cable to the color steel tile structure, achieving reasonable load distribution and transfer.

[0044] In some embodiments, the support platform 114 is covered with serrations. These serrations increase the friction between the crossbeam 200 and the support platform 114, improving the reliability of the connection.

[0045] The crossbeam 200 extends along the length parallel to the corrugated steel sheet, providing support for the cable tray 300. The crossbeam 200 is connected and fixed to the support platform 114 of the first clamping member 110 by the first connecting bolt. In actual engineering, multiple crossbeams 200 are set according to the size of the roof and the needs of cable laying. The crossbeams 200 are spaced apart along the distribution direction of the corrugated steel sheet, forming a complete support grid system for the cable tray 300.

[0046] Multiple cable trays 300 are provided, and each cable tray 300 is distributed at intervals along the length of the crossbeam 200. The bottom of the cable tray 300 is fixedly connected to the crossbeam 200, and the cable tray 300 is used to lay cables.

[0047] In some embodiments, the top and bottom of the crossbeam 200 are covered with serrations. The serrations at the top of the crossbeam 200 increase the friction between the cable tray 300 and the crossbeam 200, while the serrations at the bottom of the crossbeam 200 form a double engagement with the serrations on the support platform 114, significantly enhancing the connection stability between the crossbeam 200 and the support platform 114.

[0048] A connection hole is provided on the support platform 114, and a first connecting bolt 115 is installed in the connection hole to fix the crossbeam 200 to the support platform 114. The first clamping member 110 and the second clamping member 120 are connected by a second connecting bolt 124. The cable tray 300 is connected to the crossbeam 200 by a third connecting bolt 400.

[0049] The clamping fixing method of clamp 100 completely avoids damage to the color steel tile, maintaining the integrity of the roof and its waterproof performance, fundamentally solving the leakage risk associated with traditional drilling fixing methods. The separate clamp 100 design of the first clamping member 110 and the second clamping member 120, combined with the snap-fit ​​method of the slot 112 and the clamping block 122, as well as the bolt connection method, greatly simplifies the installation process, improves construction efficiency, and reduces installation difficulty and cost. This device effectively solves the technical problems of damaging the integrity of the color steel tile and easy leakage in traditional laying methods, achieving stable and reliable laying support for photovoltaic cables without damaging the structure of the color steel tile.

[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
