The invention discloses a ventilation device and a ship, and belongs to the technical field of ships, the ventilation device comprises a ventilation assembly and a ventilation part, the ventilation assembly comprises a weather tight cover, an air duct and a driving mechanism, the air duct is provided with an air inlet and an air outlet, and the driving mechanism can drive the weather tight cover to move between an opening position and a closing position in the axial direction of the air duct. The ventilation part is rotationally connected with the weather-tight cover, when the weather-tight cover is located at the closing position, the air outlet is closed by the weather-tight cover, and the ventilation part is arranged on the periphery of the air duct in a surrounding mode; when the weather-tight cover is located at the opening position, the weather-tight cover is far away from the air outlet, a cavity is formed between the ventilation part and the air outlet, and the ventilation part can rotate under the action of external wind so that the cavity can have negative pressure to drive airflow to flow from the air inlet to the air outlet. The ship comprises a ship body and the ventilation device, the ship body comprises a cabin, and the air inlet is communicated with the cabin. During natural ventilation, the ventilation piece rotates to promote airflow flowing, and the convection replacement effect during natural ventilation is improved.
本发明公开了一种通风装置及船舶,其属于船舶技术领域,通风装置包括通风组件和换气件,通风组件包括风雨密盖、风筒和驱动机构,风筒具有进风口和出风口,驱动机构能够驱动风雨密盖沿风筒的轴向在打开位置和关闭位置之间移动。换气件和风雨密盖转动连接,当风雨密盖位于关闭位置时,风雨密盖关闭出风口,换气件绕设于风筒外周;当风雨密盖位于打开位置时,风雨密盖远离出风口,换气件和出风口之间形成空腔,换气件能够在外界风力作用下转动以使得空腔具有负压带动气流从进风口向出风口流动。船舶包括船体和上述的通风装置,船体包括舱室,进风口与舱室连通。自然通风时,换气件转动促进了气流流动,提高了自然通风时的对流置换效果。
