At the same time, the rotation of the rotating shaft 5 drives the sealing block 66 to rotate, thereby driving the fan blades 67 outside the sealing block 66. The rotation causes the fan blades 67 to blow air, blowing out the heat generated when the shaft 5 rotates. The wind generated by the fan blades 67 passes through the through holes on the top of the water-absorbing shell 62, and blows the hot air to the water-absorbing cloth 63, drying the water-absorbing cloth 63, further improving the waterproof effect. Finally, the multiple sealing rings 69 on the outside of the shaft 5 further block the water on the shaft 5, improving the waterproof sealing performance of the wiper drainage support, and preventing rainwater from entering through the gap between the shaft 5 and the bearing seat 4 through multiple protections, avoiding rust inside the shaft 5 caused by rainwater entering, thereby improving the practicability of the wiper drainage support.
