[0021] Gear 1 (41) meshes with Gear 2 (5). An air inlet and an air outlet are provided on the monitoring box (3). A first spring is provided between the baffle (8) and the monitoring box (3). By meshing, it is ensured that Gear 1 (41) can drive Gear 2 (5) to rotate when rotating.

By providing the first spring, it is ensured that the baffle (8) can achieve self-resetting.

[0022] When this embodiment works: First, before the equipment works, the staff checks whether all components of the equipment are working properly and whether the appearance of the equipment is normal. After confirming that there is no problem, the equipment is placed at the designated position to ensure that the support legs (1) support normally without shaking. Subsequently, the first motor (2) is started, so that the first motor (2) drives the first rotating shaft (4) to start rotating. The rotation of the first rotating shaft (4) drives Gear 1 (41) to start rotating. The rotation of Gear 1 (41) drives Gear 2 (5) to start rotating. The rotation of Gear 2 (5) drives the monitoring box (3) to start rotating.
