[0026] The working principle of this utility model:

[0027] When the fan 4 needs to be inspected and maintained, the slider 604 is docked with the connecting plate 10 and fixed with bolts. After the fixation is completed, the rotating motor 701 is started.

During the rotation process, the chain 704 will drive the connecting gear 602 and the shaft block 601 to rotate through the meshing connection with the connecting gear 602. During the rotation process, the connecting gear 602 will maintain balance through the shaft connection point of the shaft block 601 and the body 1 and drive the screw rod 603 to rotate, and the screw rod 603 will drive the slider 6 when it rotates. 04 moves upward, and the slider 604 will drive the card plate 3 to follow the movement through the connecting plate 10 during the upward movement. The card plate 3 will drive the fan 4 and the intercepting net 5 to dock with the card tube 2 during the movement. After the fan 4 is completely out of the inner cavity of the card tube 2, the fan 4 can be quickly repaired. After the repair is completed, the rotating motor 701 is rotated in the opposite direction. When the output end of the rotating motor 701 rotates in the opposite direction, the transmission gear 702, chain 704, connecting gear 602, screw rod 603, slider 604 and connecting plate 10 will cooperate with each other to achieve the effect of driving the fan 4 and the intercepting net 5 to dock with the card tube 2 through the card plate 3, thereby improving the maintenance convenience of the fan 4.
