[0002] Photovoltaic power generation utilizes the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electrical energy. It primarily consists of three main components: solar panels, inverters, and grid-connected cabinets, with the majority of components being electronic components. Solar cells are connected in series and then packaged and protected to form large-scale solar cell modules. Combined with components such as power controllers, these modules form photovoltaic power generation devices.

[0033] Example 1

[0034] like Figure 1 and Figure 3 As shown, this embodiment provides a cable arrangement tool for a photovoltaic system, including a main line trough bottom plate 1, a main line trough cover plate 2 and a lead trough tube 3. The main line trough bottom plate 1 includes a U-shaped bottom plate 11 and a limiting plate 12. The limiting plate 12 is fixed to the open end of the U-shaped bottom plate 11. The limiting plate 12 is provided with a cable arrangement notch 13. The main line trough cover plate 2 is detachably fixed to the limiting plate 12.

[0035] A transfer structure 14 is provided on one side of the U-shaped bottom plate 11. The transfer structure 14 is provided with a port that cooperates with the lead trough tube 3. The lead trough tube 3 is inserted into the port, and the port is connected to the interior of the U-shaped bottom plate 11. A threaded hole and a fastening screw 15 are provided on the transfer structure 14. The fastening screw 15 abuts against the surface of the lead trough tube 3 through the threaded hole.

[0036] Working principle: Place the cables into the U-shaped bottom plate 11 from the cable arrangement slot 13 on the limiting plate 12, and then fix the main cable slot cover 2 on the limiting plate 12 to seal the cable arrangement slot 13; pass the cables on the photovoltaic panels through the lead trough tube 3 and connect them to the cables inside the main cable slot bottom plate 1, and connect the cables on the independent photovoltaic panels to the cables in the main cable slot for convergence, so as to facilitate the transmission of electricity generated by photovoltaic power generation.

[0037] By setting a transfer structure 14 on one side of the U-shaped bottom plate 11 of the main line trough and fixing the lead trough tube 3 with fastening screws 15, the structure is simple and easy to install and disassemble; and the main line trough bottom plate 1 is provided with a limit plate 12 at the upper end of the U-shaped bottom plate 11 to limit the cables placed in the U-shaped bottom plate 11, which is convenient for the subsequent installation of the main line trough cover plate 2. The cable arrangement slot 13 is convenient for cable arrangement, ensuring cable arrangement efficiency and convenience, and the structure is more reliable.

[0038] Preferred embodiment, as Figure 2 As shown, the main trunking bottom plate 1 includes multiple sections of U-shaped bottom plates 11 , and U-shaped brackets 16 are provided between adjacent U-shaped bottom plates 11 . The U-shaped brackets 16 are wrapped around the connection between the two U-shaped bottom plates 11 .

[0039] Bolt holes are provided at corresponding positions on both sides of the U-shaped bottom plate 11 and the U-shaped bracket 16 , and the U-shaped bracket 16 is bolted to the U-shaped bottom plate 11 .

[0040] The main trunking floor features a U-shaped base constructed from multiple sections. U-shaped brackets are installed at the joints, wrapping around the two U-shaped bases and bolted to each section to complete the connection. Compared to a one-piece structure, the spliced ​​U-shaped base is easier to transport and install on the roof. The U-shaped brackets effectively ensure the reliability of the connection.

[0041] Furthermore, a plurality of connecting bolts 17 are provided between the U-shaped bracket 16 and the U-shaped bottom plate 11 , and a grounding wire is connected between the connecting bolts 17 of adjacent U-shaped bottom plates 11 .

[0042] A grounding wire is provided between two adjacent U-shaped bottom plates 11 and fixed by connecting bolts 17 to improve the safety of the cable trough.

[0043] The main line trough cover plate 2 is a U-shaped cover plate, which is inverted and buckled on the main line trough bottom plate 1. The main line trough cover plate 2 and the limiting plate 12 are provided with through holes at corresponding positions, and the main line trough cover plate 2 is bolted to the limiting plate 12.

[0044] The main line duct cover plate 2 with a U-shaped structure is snapped onto the main line duct bottom plate 1. On the one hand, it is convenient for positioning the cover plate when installing the cover plate and for the stability of the subsequent bolt installation process. On the other hand, it can reduce rainwater from entering the main line duct bottom plate 1 in rainy weather after installation, thereby improving the safety and reliability of the structure.

[0045] In a preferred embodiment, a support leg 4 is provided at one end of the main line duct bottom plate 1 away from the main line duct cover plate 2, and the support leg 4 is an X-shaped structure.

[0046] Among them, a threaded hole is provided at one end of the U-shaped bottom plate 11 away from the main line duct cover plate 2, and a threaded hole corresponding to the U-shaped bottom plate 11 is provided at the symmetrical center of the support leg 4, and the U-shaped bottom plate 11 is bolted to the support leg 4.

[0047] By setting support legs 4 at the lower end of the main line duct bottom plate 1, the main line duct bottom plate 1 and the internal wiring are kept at a certain distance from the roof, avoiding the impact of water accumulation on the cables in the cable duct and improving the safety of the device.

[0048] Optionally, the support legs 4 are glued and fixed to the roof. For some roofs with colored steel tiles, that is, roofs that are not convenient for punching and installation, gluing and fixing can improve the installation efficiency of the cable trough while ensuring the reliability of the fixation.

[0049] Optionally, a mounting hole 41 is provided on the support leg 4, and the support leg 4 is fixed to the roof with bolts. For roofs that can be fixed with holes, the reliability of the cable trough fixation is ensured.

[0050] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
