Technical Field

This unidirectional arrangement has significant limitations in some operating sites, such as limited space around the transformer casing, narrow passages, and inconvenient maintenance locations. This makes fan replacement difficult and inefficient, and may even require power outages for disassembly and assembly, affecting the stability of system operation. Utility Model Content

A limiting device 11 is fixedly connected to the lower part of the handle body 2.

[0025] In a further preferred embodiment of this utility model, the slider 3 and the guide rail body 8 are detachably slidably connected, and the guide rail body 8 is installed on the guide rail mounting bracket 6 in the horizontal or vertical direction to realize the sliding withdrawal of the fan in two directions. The limiting bracket 7 is set as an L-shaped bent plate structure and is installed at the end of the guide rail body 8 away from the handle body 2. The fixing bracket 9 is connected to the handle mounting by bolts, and the bolts are detachably installed at the opening of the L-shaped structure. A locking plate 13 is fixedly connected to the outside of the guide rail mounting bracket 6.

[0026] In this embodiment, the slider 3 and the guide rail body 8 are detachably slidably connected, allowing the fan beam 4 to slide smoothly inside the guide rail while also providing quick disassembly and assembly during maintenance. This connection method balances movement flexibility and structural maintainability, facilitating the replacement or adjustment of the guide rail direction and improving on-site adaptability. The limit rod 118 is locked between the fixed bracket 9 and the locking plate 13 in a static state, achieving mechanical locking through structural interference. No additional electrical control devices are required, providing high reliability and power failure protection. When the moving plate 117 is lifted, the limit rod 118 disengages from the slot, completing the unlocking process. The entire action is intuitive and stable, suitable for frequent maintenance scenarios.

[0027] In a further preferred embodiment of this utility model, the limiting device 11 includes a fixing block 111, which is fixedly connected to the fixing bracket 9. Vertical plates 112 are symmetrically installed outside the fixing block 111. Slide grooves 113 are formed inside the vertical plates 112, and slide plates 114 are provided in both slide grooves 113. A pull plate 115 is fixedly connected to both slide plates 114.

An arc-shaped groove is provided in the connecting column 116 to facilitate hand gripping.

[0028] In this embodiment, one end of the pull-back spring 119 is fixed below the moving plate 117, forming a resetting force structure with upward and downward pulls. After releasing the hand, it can automatically return the limiting device 11 to the initial locking state, ensuring the automatic reset effect after each use, enhancing the structural reliability and reducing human intervention.

[0029] In summary, through the sliding cooperation of the fan beam 4, slider 3, and guide rail, combined with the horizontal and vertical installation methods of the guide rail, the fan body 12 can be pulled out from two directions respectively, adapting to different transformer installation environments, meeting the actual needs of uninterrupted power replacement, and improving the flexibility and maintenance efficiency of on-site operation. At the same time, the combination of L-shaped limit bracket 7 and fixed bracket 9 ensures the stability of the fan in the non-pull-out state. When the operator grasps the handle and pulls the connecting column 116, it drives the pull plate 115 to move upward, thereby pulling the limit rod 118 out of the slot of the fixed bracket 9 and locking plate 13, realizing the unlocking of the fan structure. Subsequently, the fan beam 4 can slide in the guide rail, and the operator can pull out the fan from the front or side for inspection or replacement.
