[0002] The definition of photovoltaic cable installation refers to the correct installation of photovoltaic cables into a photovoltaic power generation system to ensure that the solar energy system can operate efficiently and safely.

[0003] Cable trays for photovoltaic (PV) installation are structural systems used for installing and fixing cables. They are mainly used for the arrangement and protection of cables in PV power plants. Cable trays can effectively manage cables in PV power plants, avoid cable clutter, improve space utilization, and facilitate later maintenance and repair. Cable trays provide physical protection to prevent cables from mechanical impact, animal bites, or human damage. At the same time, some cable tray materials have fire-resistant properties, reducing the risk of fire. However, when using existing cable trays, their length is fixed. During the installation process, the length may be insufficient. Sometimes, even if only a small section of cable tray is missing, it is still necessary to cut new cable trays for assembly. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 One embodiment provided by this utility model: A cable tray for installing photovoltaic cables, comprising: The frame includes the main cable tray 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here. The extension mechanism includes an extension cable tray 2, which is slidably connected to the surface of the main cable tray 1 to extend the usable length of the main cable tray 1. A limit groove 21 is formed on the surface of the extension cable tray 2 for connecting a limit block 22. The limit block 22 is fixedly connected to the surface of the main cable tray 1 to limit the extension length of the extension cable tray 2. A guide rod 23 is fixedly connected inside the extension cable tray 2 for connecting a positioning buckle 25. A damping spring 24 is wound around the surface of the guide rod 23 to drive the positioning buckle 25 to engage with the slot 26 through its own deformation. The positioning buckle 25 is movably connected to the surface of the guide rod 23 to limit the extension position of the extension cable tray 2. The slot 26 is formed on the surface of the main cable tray 1 for engaging the positioning buckle 25.

[0019] Furthermore, the extended cable trays 2 are symmetrically distributed in two sets at both ends of the main cable tray 1, and the limiting grooves 21 are symmetrically opened in two sets on the surface of the extended cable trays 2. The two sets of extended cable trays 2 can be used to extend the main cable tray 1 from both ends of the main cable tray 1. The two sets of limiting grooves 21 are used to connect the two sets of limiting blocks 22, thereby improving the smoothness of the sliding of the extended cable trays 2.

[0020] Furthermore, the limiting blocks 22 are evenly distributed in four groups on the surface of the main cable tray 1. The extension cable tray 2 is movably connected to the surface of the limiting groove 21 and the limiting blocks 22. The sliding extension cable tray 2 can extend the cable tray 2 to change the length of the main cable tray 1.

[0021] Furthermore, the guide rods 23 are symmetrically distributed in two sets inside the extended cable tray 2. The positioning buckle 25 is movably connected to the surface of the extended cable tray 2 through the guide rods 23. When the extended cable tray 2 moves, the positioning buckle 25 abuts against the surface of the main cable tray 1, thereby causing the damping spring 24 to deform.

[0022] Furthermore, the two ends of the damping spring 24 are fixedly connected to the inside of the extended cable tray 2 and the surface of the positioning buckle 25. The positioning buckle 25 is engaged with the surface of the groove 26 through the damping spring 24. The groove 26 is evenly opened on the surface of the main cable tray 1. When the extended cable tray 2 is extended and retracted to a suitable position, the positioning buckle 25 can be engaged into the groove 26. The damping spring 24 drives the positioning buckle 25 to engage in the groove 26 in order to return to its original shape, thereby limiting the extension and retraction position of the extended cable tray 2 and fixing the service length of the main cable tray 1.

[0023] Furthermore, the splicing mechanism includes a splicing cable tray 3, which acts on the surface of the extended cable tray 2 to splice the extended cable tray 2, allowing multiple main cable trays 1 to be spliced ​​together. The surface of the splicing cable tray 3 is fixedly connected to an installation block 31 for engaging splicing clips 34. The surface of the extended cable tray 2 is fixedly connected to a connecting block 32 for installing the installation block 31. The surface of the connecting block 32 is fixedly connected to a connecting base 33 for connecting the splicing clips 34. The surface of the connecting base 33 is fixedly connected to a splicing clip 34 for engaging at the installation block 31, thus fixing the splicing position of the extended cable tray 2 and the splicing cable tray 3.

[0024] Furthermore, the mounting blocks 31 are symmetrically distributed in two sets on both sides of the splicing cable tray 3, and the connecting blocks 32 are symmetrically distributed in two sets on both sides of the extension cable tray 2. The two sets of connecting blocks 32 are used to connect the two sets of mounting blocks 31. The splicing cable tray 3 and the extension cable tray 2 have the same structure. For ease of explanation, they are described separately in this application. The mounting blocks 31 are connected by the abutment of the surfaces of the splicing cable tray 3 and the connecting blocks 32, so that the splicing cable tray 3 is installed on the surface of the extension cable tray 2, and the mounting blocks 31 are installed on the surface of the connecting blocks 32.

[0025] Furthermore, the splicing buckles 34 are evenly distributed in four groups on the surface of the connecting base 33. The connecting base 33 is connected by the surface of the connecting block 32 and the mounting block 31. The splicing buckles 34 are connected by the surface of the connecting base 33 and the mounting block 31, so that the connecting base 33 is inserted into the surface of the mounting block 31 and the splicing buckles 34 are deformed and locked at the mounting block 31, thereby fixing the splicing position of the extension cable tray 2 and the splicing cable tray 3.

[0026] Working principle: When using the main cable tray 1, firstly, slide the telescopic extension cable tray 2 to change the length of the main cable tray 1. Extend the extension cable tray 2 to a suitable position so that the positioning buckle 25 can be engaged in the slot 26. The damping spring 24 returns to its original shape, causing the positioning buckle 25 to engage in the slot 26, thereby limiting the extension position of the extension cable tray 2 and fixing the length of the main cable tray 1. Then, as needed, splice multiple sets of main cable trays 1 and install the spliced ​​cable tray 3 on the surface of the extension cable tray 2 so that the mounting block 31 is installed on the surface of the connecting block 32, so that the connecting base 33 is inserted into the surface of the mounting block 31. The splicing buckle 34 deforms and engages in the mounting block 31, thereby fixing the splicing position of the extension cable tray 2 and the spliced ​​cable tray 3.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
