A fire-resistant photovoltaic cable installation device

Abstract

This utility model discloses a fire-resistant photovoltaic cable installation device, relating to the field of cable installation technology. It includes a fixed rail with multiple fixing devices slidably mounted on its top. The fire-resistant photovoltaic cable installation device of this utility model utilizes elastic clips and rubber pads. Because the elastic clips are made of elastic material, their own reaction force clamps and fixes the cable, while the rubber pads support the cable's outer surface, preventing wear caused by the clamping of the elastic clips. Simultaneously, it insulates the rotating ring from the cable and is adaptable to cables of different diameters. The cable can be fixed at any position on the top of the fixing frame. The reaction force of the fixing spring causes the plug to insert into the snap-fit ​​hole, allowing the rotating ring to rotate in different directions on the top of the fixing column. This allows the rotating ring to be freely adjusted according to the cable wiring scenario, improving the flexibility of cable installation.

[0002] With the increasing global demand for renewable energy, photovoltaic (PV) power generation, as a clean and sustainable energy form, has been widely applied and developed. PV cables, as a key component of PV power generation systems, bear the important responsibility of transmitting electrical energy. Among existing technologies, some PV cables with fire-resistant properties have emerged. For example, some cables improve their fire resistance by using highly flame-retardant materials as insulation and sheathing.

[0003] However, existing fire-resistant photovoltaic cable installation devices rely on a limited range of cable fixing methods during installation, making it difficult to adapt to cables of different specifications and shapes. This can easily lead to loosening or displacement of the cables after installation, affecting their normal operation and fire resistance. Furthermore, in complex photovoltaic power plant wiring scenarios, traditional fixing clamps cannot be flexibly adjusted due to the intricate cable routing, resulting in inconvenience and significant limitations.

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0016] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a fire-resistant photovoltaic cable installation device, including a fixed rail 1 and multiple fixing devices 2, wherein the multiple fixing devices 2 are slidably installed on the top of the fixed rail 1; like Figure 4 As shown, the fixing device 2 includes a connecting seat 21 and a rotating ring 26. A fixing plate 22 is fixedly installed in the middle of the connecting seat 21. Multiple snap-fit ​​holes 23 are opened on the top of the fixing plate 22. A fixing column 24 is fixedly installed on the top of the fixing plate 22. A movable column 210 is movably sleeved inside the fixing column 24. A top plate 25 is fixedly installed on the top of the movable column 210. A positioning plate 211 is fixedly installed on the bottom of the movable column 210. Multiple plug bolts 213 are fixedly installed on the bottom of the positioning plate 211. The rotating ring 26 is rotatably installed at both ends of the top of the top of the top plate 25. A connecting block 27 is fixedly installed on the top of both ends of the rotating ring 26. Fixing bolts are installed in the internal threads of the connecting blocks 27 at both ends.

[0017] Among them, a fixed spring 212 is movably sleeved on the outer surface of the movable column 210, and the fixed spring 212 is located between the top of the positioning plate 211 and the top wall of the fixed column 24.

[0018] The snap-fit ​​holes 23 are distributed in a circumferential shape on the top of the fixing plate 22. The number of plugs 213 corresponds to the number of snap-fit ​​holes 23, and the position of the plugs 213 corresponds to the position of the snap-fit ​​holes 23. The plugs 213 are inserted and installed inside the snap-fit ​​holes 23.

[0019] Specifically, by setting a positioning plate 211, a plug 213, and a locking hole 23, and by pulling up the rotating ring 26, the movable column 210 moves inside the fixed column 24, the positioning plate 211 rises, compressing the fixed spring 212, and the plug 213 moves out of the locking hole 23. By rotating the rotating ring 26, the positioning plate 211 rotates inside the fixed column 24, and through the reaction force of the fixed spring 212, the plug 213 is inserted into the locking hole 23. This allows the rotating ring 26 to rotate in different directions at the top of the fixed column 24, enabling the rotating ring 26 to be freely adjusted according to the cable wiring scenario, thus improving the flexibility of cable installation.

[0020] Among them, elastic cards 28 are fixedly installed on the inner walls of the rotating rings 26 at both ends, rubber pads 29 are fixedly installed on the sides of the elastic cards 28, and locking parts 3 are snapped into the bottom of the connecting seat 21.

[0021] Specifically, by setting up elastic clips 28 and rubber pads 29, since the elastic clips 28 are made of elastic material, the cable is clamped and fixed by the reaction of the elastic clips 28 themselves, and the outer surface of the cable is supported by the rubber pads 29 to prevent the cable from being worn due to the clamping of the elastic clips 28. At the same time, insulation is formed between the rotating ring 26 and the cable, the cable is quickly fixed, and it can be adapted to cables of different diameters.

[0022] like Figure 5 As shown, the locking component 3 includes two locking rods 31, and a fixing block 32 is fixedly installed at both ends of the two locking rods 31. A locking bolt 33 is fixedly installed on the top of the fixing blocks 32 at both ends, and a locking nut 34 is threaded on the outer surface of the locking bolt 33.

[0023] like Figure 2 As shown, the fixed track 1 includes a fixed frame 11, with mounting blocks 12 fixedly installed on both sides of the fixed frame 11. Sliding grooves 13 are provided on both sides of the top of the fixed frame 11. An active cavity 14 is provided inside the fixed frame 11. Fixed racks 15 are fixedly installed on both sides of the top wall of the active cavity 14.

[0024] The connecting seat 21 is slidably mounted on the outer surface of the fixed frame 11, the fixed block 32 is slidably mounted inside the movable cavity 14, the two snap-fit ​​rods 31 are snap-fitted onto the bottom of the two fixed racks 15, the locking bolt 33 is slidably mounted inside the sliding groove 13, and the connecting seat 21 is connected to the fixed block 32 by the locking nut 34.

[0025] Specifically, the locking rod 31 and the fixing block 32 can move inside the movable cavity 14, and the connecting seat 21 slides on the outer surface of the fixing frame 11. When the fixing device 2 moves to a place on the fixing frame 11, the locking bolt 33 drives the fixing block 32 and the locking rod 31 to move upward by rotating the locking nuts 34 at both ends, so that the locking rod 31 is locked into the bottom of the fixing rack 15 inside the fixing frame 11, so that the fixing device 2 can be fixed at any place on the fixing frame 11, and the cable can be fixed at any position on the top of the fixing frame 11, improving the flexibility of cable installation.

[0026] The working process of this utility model is as follows: In use, depending on the cable wiring scenario, rotate the locking nuts 34 at both ends to lower the snap-fit ​​rod 31 and the fixing block 32 at the bottom of the fixing rack 15. At this time, push the connecting seat 21 to slide on the top of the fixing frame 11. According to the position of the cable, rotate the locking nuts 34 at both ends to move the locking bolt 33 to move the fixing block 32 and the snap-fit ​​rod 31 upward, so that the snap-fit ​​rod 31 snaps into the bottom of the fixing rack 15 inside the fixing frame 11, thereby locking the fixing device 2 at the top of the fixing frame 11 according to the position of the cable. According to the cable routing, by pulling up the rotating ring 26, the movable column 210 moves inside the fixed column 24, the positioning plate 211 rises, compressing the fixed spring 212, and the plug 213 moves out of the snap-fit ​​hole 23. By rotating the rotating ring 26, the positioning plate 211 rotates inside the fixed column 24, and the reaction force of the fixed spring 212 causes the plug 213 to be inserted into the snap-fit ​​hole 23. Thus, the rotating ring 26 rotates to different positions on the top of the fixed column 24 according to the cable routing, which facilitates the installation of the cable. Subsequently, the cable is placed between the two rotating rings 26. By rotating the rotating rings 26, the elastic clips 28 and rubber pads 29 on both sides of the two rotating rings 26 compress the two sides of the cable. Since the elastic clips 28 are made of elastic material, the cable is clamped and fixed by the reaction of the elastic clips 28 themselves, and the outer surface of the cable is supported by the rubber pads 29 to prevent the cable from being worn due to the clamping of the elastic clips 28. Then, the rotating rings 26 at both ends are locked by fixing bolts, thereby keeping the cable fixed and installed.
