Description

Technical Field

[0001] This utility model relates to the field of transformer box technology, specifically a transformer box with flame extinguishing function. Background Technology

[0002] The transformer box contains various components, including transformers, circuit breakers, disconnect switches, meters, and relays. These components all need to be in contact with cables, making it a place where fires can easily occur due to short circuits or other reasons.

[0003] In existing technologies, fire extinguishing agents or flame extinguishing patches are typically installed in transformer boxes for fire suppression. These flame extinguishing patches are made of flame-retardant hot melt adhesive encapsulating flame extinguishing microcapsules containing the fire extinguishing agent. The patches are installed 2-10 cm away from components; when heated above 100°C, the microcapsules rupture, releasing the fire extinguishing agent. However, due to the numerous wiring connections within transformer boxes, flame extinguishing patches are usually fixed using bolts or adhesive, making it difficult to adjust their position when wiring changes. Therefore, we propose a transformer box with flame extinguishing functionality to address these issues. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a transformer box with flame extinguishing function, comprising: a transformer box body 1, components 2 installed inside the transformer box body 1, a cable tie box 3 provided on one side of the components 2, a cable tie box 3 having a wire insertion hole 4 on the surface of the cable tie box 3 near the components 2, a moving rail 8 installed at one end of the cable tie box 3, and a moving block 9 slidably connected to the inner wall of the moving rail 8; the cross-section of the cable tie box 3 is U-shaped, and a plurality of heat dissipation holes 7 are evenly provided on the surface of the cable tie box 3 near the wire insertion hole 4. A mounting plate 5 is fixedly installed on the side wall of the cable tie box 3, and mounting screws 6 are installed between the mounting plate 5 and the inner wall of the transformer box body 1, facilitating the assembly and disassembly of the cable tie box 3 by means of mounting screws 6. The mounting plate 5 can be fixedly installed on the cable tie box 3 by means of bolts or welding. The moving track 8 is fixedly installed on the cable tie box 3. The moving block 9 is T-shaped. One end of the moving block 9 is slidably connected to the inner wall of the moving track 8, and the other end of the moving block 9 slides out of the moving track 8. Depending on the number of components 2 and connecting lines, several moving blocks 9 can be inserted through one end of the moving track 8. The moving track 8 can longitudinally limit the moving blocks 9.

[0024] A threaded sleeve 10 is installed at one end of the movable block 9. A magnet 11 is provided on the surface of the threaded sleeve 10 near the movable track 8. A threaded rod 12 is threadedly connected to the inner wall of the movable track 8. An adjusting rod 16 is installed at one end of the threaded rod 12. A fixing plate 14 is installed at one end of the adjusting rod 16 near the component 2. A flame extinguishing patch 15 is provided at one end of the fixing plate 14. The flame extinguishing patch 15 is made of flame-retardant hot melt adhesive wrapped with flame extinguishing microcapsules. It utilizes the principle that the flame extinguishing microcapsules will rupture on their own when heated to above 100°C to release the fire extinguishing agent, thereby extinguishing the fire at the connection line where it is burning. One end of the threaded sleeve 10 is fixedly mounted on the movable block 9. Magnet blocks 11 are fixedly mounted on the top and bottom of the end of the threaded sleeve 10 closest to the movable block 9. Both magnet blocks 11 are magnetically attracted to the surface of the moving track 8. The iron material of the moving track 8 facilitates lateral positioning of the movable block 9 using the magnet blocks 11. Lateral movement of the movable block 9 requires external force to pull the threaded sleeve 10 laterally. Threaded rods 12 can be inserted into the openings at both ends of the threaded sleeve 10, allowing for selective installation of the threaded rods 12 based on the location of the components 2 and connecting lines. One end of the fixing plate 14 is fixedly mounted on the adjusting rod 16, and the other end of the fixing plate 14 is fixedly connected to the flame extinguishing patch 15. The flame extinguishing patch 15 can be fixed to the fixing plate 14 by adhesive or magnetic attraction.

[0025] A threaded groove 13 is formed at one end of the threaded rod 12 near the adjusting rod 16. An adjusting screw 17 is threadedly connected to the inner wall of the threaded groove 13. Several adjusting holes 18 are evenly formed on the surface of the adjusting rod 16 near the adjusting screw 17. One end of the adjusting screw 17 passes through an adjacent adjusting hole 18 and is rotated into the threaded groove 13. The adjusting rod 16 is fixedly installed at one end of the threaded rod 12 through the threaded connection between the adjusting screw 17 and the threaded groove 13.

[0026] When this device is in operation, the connecting wires at one end of component 2 can be passed through the wiring box 3 on one side of component 2 and stored in the wiring box 3, facilitating the organization of the connecting wires inside the transformer box body 1. Using the movable track 8, movable block 9, and magnet 11, the threaded sleeve 10 can be pulled to adjust the movable block 9 to a suitable position. The magnetic attraction between the magnet 11 and the movable track 8 then limits the movable block 9, making it easier to adjust the position of the threaded sleeve 10 along the movable track 8. The threaded rod 12 is connected to the inner wall of the threaded sleeve 10. To facilitate the adjustment of the length of the threaded rod 12 extending out of the threaded sleeve 10 by rotating the threaded rod 12, i.e. adjusting the distance between the adjusting rod 16 and the threaded sleeve 10, and then aligning one of the adjusting holes 18 on the adjusting rod 16 with the threaded groove 13, it is convenient to adjust the distance between the flame extinguishing patch 15 and the threaded rod 12, so as to prevent the flame extinguishing patch 15 from being too close or too far from the connection line. By passing one end of the adjusting screw 17 through the corresponding adjusting hole 18 and rotating it into the threaded groove 13, the adjusting rod 16 can be fixed on the threaded rod 12 by adjusting the adjusting screw 17, thereby realizing the function of adjusting the installation position of the flame extinguishing patch when the connection line changes.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
