The specific application principle of the invention is as follows:

automatically controlling the opening and closing of the movable fan:

the electric telescopic rod 11 controls the push head 10 to extend forwards, the movable base 7 or the steering assembly 8 or the mounting seat of the driving gear 9 is extruded through the inclined plane of the push head 10, the movable base 7 is subjected to downward extrusion force, the movable base 7 rotates around the movable shaft 6, the driving gear 9 descends, the driving gear is meshed with the rack 4 after penetrating through the driving groove 52, the driving motor 17 is started, the motor shaft of the driving motor 17 rotates in the vertical direction, the driving gear 9 is driven to rotate after conversion of the steering assembly 8, and the driving gear 9 drives the rack 4 to move, so that the movable fan 1 is driven to open and close.

Manually controlling the opening and closing of the movable fan:

the driving motor 17 is powered off, the electric telescopic rod 11 is powered off, the push head 10 of the electric telescopic rod 11 is in a retracted state, and the movable base 7 is turned upwards around the movable shaft 6 under the torsion action of the return spring 14, so that the driving gear 9 is lifted and separated from meshing with the rack 4; at this time, the movable fan 1 can be easily pushed to open and close manually.

Fine tuning control:

the driving device needs to carry out displacement adjustment during installation, one is to adjust the position of the driving gear 9, and the other is to adjust the descending distance of the driving gear 9.

Adjustment of the horizontal position of the drive gear 9: the wrench is inserted into the wrench hole 22 of the second worm 15, so that the second worm 15 is controlled to rotate, the second worm 15 rotates to drive the second rack plate 16 to horizontally move back and forth, the second rack plate 16 is connected with the movable shaft 6, and the movable shaft 6 is arranged in the bar-shaped hole 51, so that the movable base 7 integrally moves back and forth along with the horizontal movement, and the driving gear 9 horizontally moves back and forth.

Up and down position adjustment of the drive gear 9: the spanner is inserted into the spanner hole 22 of the first worm 12, the first worm 12 is controlled to rotate, the first rack plate 13 is driven to horizontally move back and forth by the rotation of the first worm 12, the first rack plate 13 is connected with the electric telescopic rod 11, therefore, the basic position of the electric telescopic rod 11 is changed, the position of the push head 10 is changed, when the basic position of the push head 10 moves forward, the push head 10 stretches out, longer-distance extrusion can be generated on the steering assembly 8, and as the bottom surface of the push head 10 is an inclined surface, the movable base 7 is enabled to downwards overturn by more angles around the movable shaft 6, and the driving gear 9 descends by more distances. The reverse direction then drives the gear wheel 9 down a smaller distance.
