The application provides a ship and a propeller setting method. The ship comprises a ship body. When the ship body enters water, the bottom of the ship body is immersed in water; a channel is formed in the bottom of the ship body and used for arranging a propeller, and an outlet of the channel is located in the tail of the bottom of the ship body; and the inner diameter of the channel between thepropeller and the outlet is not larger than the positioning inner diameter, the diameter of the propeller is smaller than the positioning inner diameter, the difference ratio of the diameter of the propeller to the positioning inner diameter does not exceed a preset difference ratio, the positioning inner diameter represents the inner diameter of the channel where the propeller is arranged, and the preset difference ratio is between 0 and 0.3. When the propeller is arranged in the channel, the water flow in the channel is pushed to the outlet direction when the propeller rotates. Therefore, the divergence angle when the propeller pushes the water flow backwards during operation can be effectively reduced, the thrust generated by the water flow is close to the forward and backward directions, so that the utilization efficiency of energy is improved, and the effect of saving energy is achieved. Meanwhile, water flows through the channel at the bottom of the ship body to improve the stability of the ship body.
本申请提供一种船舶及螺旋桨的设置方法,船舶包括船体,船体入水时,船体底部浸没于水中,船体底部设有通道,用于设置螺旋桨,通道的出口位于船体底部的尾部;螺旋桨与出口之间的通道的内径不大于定位内径,螺旋桨的直径小于定位内径,且螺旋桨的直径与定位内径的差异比例不超过预设差异比例,其中,定位内径表示设置螺旋桨处的通道的内径,预设差异比例在0至0.3之间;其中,在螺旋桨设置于通道内时,螺旋桨转动时将通道内的水流向出口方向推送。这样可以有效减小螺旋桨运行时将水流向后推动时的发散角,使得水流产生的推力接近前后反向,从而提升能量的利用效率,从而达到节约能源的效果。同时船体底部的通道内有水流通过可以提高船身稳定性。
