The unfolded sliding frame and the unfolded support frame cooperatively provide accurate positioning sliding support for the sliding support column; the fixed bolt cooperates with the locking groove to reliably limit and lock the rotation of the unfolded support frame, so that the structural stability is ensured. On this basis, the sliding support column provides flexible rotating support for the bearing support frame as a whole through the cooperation of the positioning support block and the rotating connecting block, so that the bearing support frame can support the accurate positioning of the two groups of protective side covers on the fan side. When the two groups of protective side covers are connected through the rotation of the bearing support frame, the fan can be effectively shielded and protected; at the same time, the locking support block cooperates with the locking clamping groove to drive the locking clamping block to complete the connection and locking of the first support block and the second support block, so that the connection stability of the two groups of protective side covers is further improved, and the protection effect is ensured. When the fan needs maintenance and repair after long-term use, the operation convenience is significantly improved: the abutment locking of the first support block and the second support block is released by rotating the locking support block, after the fixing bolts are disassembled, the support frame is unfolded and can be flexibly rotated and adjusted, and then the two groups of bearing support frames are slidably unfolded by the sliding support column. In this process, the bearing support frame drives the protective side cover to separate from the fan protection area, and the positioning support block and the rotating block support the bearing support frame to further rotate and unfold the protective side cover, so that the fan structure is completely exposed, thereby realizing stable and fast maintenance and repair operation, and greatly improving the maintenance efficiency; The overall structure not only ensures reliable protection of the fan during daily use, but also simplifies the operation steps in the maintenance process through modular linkage design, and balances the protection stability and maintenance convenience.
