The vertical telescopic rotary air duct comprises a base, a supporting shaft, a lower-layer air duct body and an upper-layer air duct body, the base is arranged above an exposed deck, the supporting shaft is fixed above the base, the lower-layer air duct body is arranged outside the supporting shaft in a sleeving mode and located above the base, and the upper-layer air duct body is arranged outside the lower-layer air duct body in a sleeving mode; the supporting shaft is provided with a first driving device for driving the lower-layer air duct to rotate, and a second driving device for driving the upper-layer air duct to move up and down relative to the lower-layer air duct is arranged in the upper-layer air duct; and a limiting device for limiting the upper-layer air duct to rotate relative to the lower-layer air duct is arranged between the upper-layer air duct and the lower-layer air duct. According to the vertical telescopic rotary air duct, the height of the air duct is adjusted through the relative telescopic displacement between the upper-layer sleeve and the lower-layer sleeve which are arranged above an exposed deck, and the occupied space of a ship body below the deck cannot be increased while the trafficability of a ship is improved.

    本发明涉及一种安装在船舶上的垂向伸缩式旋转风筒,包括基座、支撑轴、下层风筒、上层风筒,基座设置在露天甲板上方,支撑轴固定在基座上方,下层风筒套设在支撑轴外部并位于基座上方,上层风筒套设在下层风筒外部;支撑轴设置有驱动下层风筒转动的第一驱动装置,上层风筒内设置有用以驱动上层风筒相对下层风筒上下移动的第二驱动装置;上层风筒和下层风筒之间设置有限制上层风筒相对下层风筒转动的限位装置。本发明的垂向伸缩式旋转风筒通过设置在露天甲板上方,上层套筒和下层套筒之间的相对伸缩位移实现风筒高度的调节,实现提高船舶通过性的同时不会增加对甲板下方船体空间的占用。
