The invention provides a liftable buoyancy tank device of a semi-submersible transport ship. The liftable buoyancy tank device comprises a deck, a flap type rudder and a buoyancy tank, the flap type rudder is connected to the tail of the bottom end of the deck, one side of the bottom end of the flap type rudder is in threaded connection with the buoyancy tank through a buoyancy shaft, and a buoyancy shaft circular shaft is in attached sleeving connection with the peripheral surface of the buoyancy shaft through a cylindrical groove of a rotating groove in one side surface of the flap type rudder. The liftable buoyancy tank device of the semi-submersible transport ship is provided with the buoyancy shaft; through the buoyancy shaft, the transport ship can ascend and descend through buoyancywhen diving; due to the fact that the buoyancy shaft upper lifting shaft is connected with the buoyancy tank in a threaded embedded mode, the buoyancy tank can be forced to ascend and descend in theopposite direction when the buoyancy shaft ascends to drive the lifting shaft to rotate and ascend, the buoyancy tank on the transport ship can ascend and descend automatically according to the descending and ascending conditions of transport, and loading and unloading of goods of the transport ship cannot be hindered.

    本发明提供了一种半潜运输船的可升降浮箱装置,包括甲板、襟翼舵和浮箱,甲板底端尾部连接有襟翼舵,襟翼舵的底端一侧通过浮力轴与浮箱螺纹连接,浮力轴圆轴通过襟翼舵一侧表面旋转槽的圆柱开槽对浮力轴的周围表面进行贴合套接连接。该种半潜运输船的可升降浮箱装置设置有浮力轴,通过浮力轴能够在运输船下潜的时候通过其浮力而进行升降,而因为其浮力轴上升降轴与浮箱的螺纹嵌合连接使得在浮力轴上升带动升降轴旋转升降的时候会迫使其浮箱向反方向进行升降,使得其运输船上的浮箱能够更具去运输的下潜上升情况自行升降使得其不会妨碍其货物的装卸。
