[0002] A multi-stage circulating water-cooled cooling tower is a device that uses water and air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation to ensure the normal operation of the equipment system. The device is generally barrel-shaped, and the air inlet grille is generally installed at the location where air is needed in the cooling tower.

[0003] However, when the existing multi-stage circulating water-cooled cooling tower is in use, dust and other impurities are easily adhered to the air inlet grille, which is very inconvenient to clean and will affect the air intake effect. Summary of the invention
