[0010] Furthermore, the regulating wind plate includes a plurality of wind plates, a connecting shaft and a motor. The plurality of wind plates are evenly distributed in the wind duct holes of the main deck along the length of the ship. One end of each wind plate is connected to a motor through a connecting shaft.

[0011] Furthermore, the cross-section of each wind plate is elliptical, and the maximum width of the wind plate is less than 1 / 4 of the width of the air duct hole on the main deck.

[0012] Furthermore, a plurality of lightening holes are provided on the air duct wall at intervals from top to bottom.

[0013] The utility model provides a ship air duct structure, which increases the effective commercial vehicle-carrying area of ​​the deck by adopting an L-shaped air duct structure, adjusts the fan efficiency, reduces the production process cost, and improves the economic benefit of ship operation.
