[0017] (3) The moisture-proof electrical cabinet sealing device for the wind power station drives the rotating rod to rotate through the rotation of the gear, and the rotation of the rotating rod drives the stirring rod to rotate. The rotation of the stirring rod stirs the activated carbon particles inside the mesh frame. The activated carbon can absorb moisture and remove moisture from the air in the cabinet. The rotation of the stirring rod can help the activated carbon particles to maintain a uniform distribution, thereby avoiding the accumulation or agglomeration of the activated carbon particles and ensuring that the surface area of ​​the activated carbon is maximized. The vibration of the arc rod drives the vibration of the rotating rod, and the vibration of the rotating rod drives the vibration of the stirring rod to improve the stirring effect of the stirring rod. The vibration of the stirring rod can further improve the loose state between the activated carbon particles. BRIEF DESCRIPTION OF THE DRAWINGS
