Water-proof shutter ventilation structure

The invention provides a water-proof shutter ventilation structure, a fan cover is mounted at a ship ventilation opening, a water-stop sheet is arranged at the bottom of the fan cover, a ventilation barrel is mounted at a partition air opening of the water-stop sheet, a water baffle is mounted at the top of the ventilation barrel and is higher than a ventilation grille mounted on the side wall of the fan cover, a drainage hole is formed in the position, located at the water-stop sheet, of the fan cover, and the outer side of the fan cover is further provided with a flexible wave stopping plate capable of shielding the drainage hole. Through the arrangement of the water-proof shutter ventilation structure, ventilation can be ensured, and meanwhile, bad water or rainwater can be effectively prevented from entering a watertight compartment of a ship, so that the safety and the operation reliability of the ship or an overwater facility are ensured; the water-proof shutter ventilation structure can be widely appli
