[0001] This utility model belongs to the field of cable trays, and in particular relates to a cable tray for photovoltaic inverters. Background Technology

[0002] Cable trays are devices used to support and protect cables, wires, and other wiring. In photovoltaic power generation technology, photovoltaic inverters convert the direct current generated by photovoltaic panels into alternating current. The photovoltaic inverters are usually connected to cables for transmission, and these cables are typically laid inside the cable trays to protect the photovoltaic inverter cables.

[0003] In existing technologies, multiple cable trays are often spliced ​​together for use in actual applications. Adjacent cable trays are usually connected by bolts. In order to tighten the bolts, appropriate disassembly and assembly tools such as wrenches are usually required. This means that appropriate disassembly and assembly tools must be carried for installation, which increases the tool burden on installers. To address this issue, we provide a cable tray for photovoltaic inverters to solve the above problems. Utility Model Content

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0029] like Figures 1-8 As shown, this utility model is a cable tray for a photovoltaic inverter, including a cable tray 1, a protective cover 2, a positioning block 19, a docking structure, a connecting structure, a limiting structure, and a fixing structure.

[0030] like Figures 1-8 As shown, a detachable protective cover 2 and two positioning blocks 19 fixedly connected to the lower surface of the cable tray 1 are provided on the cable tray 1. There are two cable trays 1, which are symmetrically distributed. A detachable docking structure is provided on the cable tray 1. The docking structure includes a detachable connecting plate 6 movably connected to the cable tray 1, two positioning grooves 7 opened on the connecting plate 6, the outer surface of the positioning block 19 movably connected to the positioning groove 7, two connecting shafts 8 fixedly connected to the connecting plate 6, multiple movable plates 9 rotatably connected to the connecting shafts 8, slots 10 opened on the movable plates 9, and multiple connecting structures provided on the cable tray 1.

[0031] The connection structure includes a support block 3 fixedly connected to the cable tray 1, an insert block 4 fixedly connected to the support block 3 and movably connected to the slot 10, and a fixing structure disposed on the support block 3.

[0032] The fixing structure includes an anti-detachment block 11 slidably connected to the inner surface of the support block 3, a slide rod 12 fixedly connected to the side surface of the anti-detachment block 11, a slider 13 fixedly connected to the slide rod 12, a fixing block 14 fixedly connected to the side surface of the slider 13, a fixing groove 15 opened on the movable plate 9 and movably connected to the fixing block 14, and an insert rod 17 fixedly connected to the upper surface of the slider 13. The outer surface of the fixing block 14 is movably connected to the support block 3, the outer surface of the slide rod 12 is slidably connected to the support block 3, and a spring 16 is slidably sleeved on the outer surface of the slide rod 12. One end of the spring 16 is fixedly connected to the side surface of the anti-detachment block 11, and the end of the spring 16 away from the anti-detachment block 11 is fixedly connected to the inner side wall of the support block 3.

[0033] In this embodiment, by pulling the protective cover 2 upwards, the protective cover 2 and the structure on the protective cover 2 can be removed from the cable tray 1, thereby releasing the fixation on the insertion rod 17. Then, pulling the insertion rod 17 allows the moving insertion rod 17 to drive the slider 13, the fixing block 14, the sliding rod 12, and the anti-detachment block 11 to move. During the movement, the anti-detachment block 11 gradually compresses the spring 16, thus keeping the spring 16 in a taut state. When the moving fixing block 14 disengages from the fixing groove 15, the fixation is released. The movable plate 9 is fixed, then it is flipped so that the movable plate 9 and the slot 10 rotate around the connecting shaft 8. When the flipped slot 10 disengages from the insert block 4, the fixing of the cable tray 1 is released. Then the insert rod 17 is released, so that the spring 16 is no longer restricted by tension and rebounds. The rebounding spring 16 can drive the anti-disengagement block 11, the slide rod 12, the slider 13, the fixing block 14, and the insert rod 17 to move back to their original positions. Then the cable tray 1 is pulled upward, which can separate the two cable trays 1. When connecting two cable trays 1, first align the ends of the two cable trays 1, then insert the two positioning slots 7 on the connecting plate 6 into the positioning blocks 19 of the two cable trays 1 respectively. Then pull the insertion rod 17, so that the moving insertion rod 17 drives the anti-disengagement block 11, the sliding rod 12, the slider 13 and the fixing block 14 to move, while keeping the spring 16 in a taut state. When the moving fixing block 14 no longer affects the flipping of the movable plate 9, flip the movable plate 9 in the opposite direction, so that the movable plate 9 and the slot 10 flip in the opposite direction. When the flipped slot 10 is inserted into the plug block 4, the plug rod 17 is released, so that the spring 16 is no longer restricted by the tension and rebounds. The rebounding spring 16 can drive the anti-disengagement block 11, the slide rod 12, the slider 13, the fixing block 14 and the plug rod 17 to move back to their original positions. When the moving fixing block 14 enters the fixing groove 15, one of the cable trays 1 is fixed. Then the above operation is repeated on the other side to fix the other cable tray 1, thereby realizing the docking between the two cable trays 1. Specific Implementation Example 2

[0034] like Figures 1-2 As shown, this utility model is a cable tray for a photovoltaic inverter. Compared with Embodiment 1, in this embodiment, the limiting structure includes a limiting block 5 fixedly connected to the protective cover 2 and a limiting groove 18 opened on the limiting block 5. The inner surface of the limiting groove 18 is movably connected to the insertion rod 17.

[0035] In this embodiment, after the two cable trays 1 are connected and the photovoltaic inverter cables are laid, the limiting groove 18 on the limiting block 5 is inserted into the plug rod 17. This not only enables the connection between the cable tray 1 and the bearing block 3, allowing the bearing block 3 to protect the cables in the cable tray 1, but also fixes the plug rod 17, preventing it from moving. This prevents the fixing block 14 from coming out of the fixing groove 15, thereby improving the stability of the two cable trays 1 after connection.
