The invention discloses a drifting steamship, which comprises a steamship body and propellers pushing the steamship body to sail, wherein the propellers are arranged at the bottom of the steamship body in pairs; each pair of propellers comprises two propellers which are symmetrically distributed on the two sides of the axis of the steamship body, the propellers can deflect by +/-alpha relative to the installation position, and alpha ranges from 30 degrees to 60 degrees; when the deflection angle of the propeller is alpha, thrust for pushing the steamship body to move forwards and upward acting force for supporting the steamship body can be generated at the same time; when the deflection angle of the propeller is -alpha, thrust for pushing the steamship body to retreat and upward acting force for supporting the steamship body can be generated at the same time. Therefore, the propeller is arranged at the bottom of the steamship and can deflect by +/-alpha relative to the mounting position, the gripping force of the propeller can be increased by utilizing the buoyancy of water, the influence of water flow on the propeller is effectively reduced, and the speed increasing limit value is increased.
本发明公开了一种漂移轮船,包括船体和推动船体航行的螺旋桨,所述螺旋桨布置在船体的底部,并成对布置;每对螺旋桨均包括对称分布在船体轴线两侧的两个螺旋桨,且螺旋桨能够相对于安装位置处偏转±α,α取值为30°‑60°;当螺旋桨偏转的角度为α时,能够同时产生推动船体前行的推力以及托起船体的向上作用力;当螺旋桨偏转的角度为‑α时,能够同时产生推动船体后退的推力以及托起船体的向上作用力。由此可知,本发明将螺旋桨设置在轮船底部,并能够相对于安装位置处偏转±α,可以利用水的浮力来增加螺旋桨的抓着力,有效地减少水流对螺旋桨的影响,从而提高航速增速的极限值。
