The invention relates to the technical field of propellers, in particular to an underwater shell, a pod propeller and a ship. The underwater shell comprises a pod shell, a thruster shell, a front shell and a rear shell, the top of the pod shell can be arranged on the ship body in a sealed mode, the bottom of the pod shell is communicated with the thruster shell, and a propeller shaft of the propeller can penetrate out of the two ends of the thruster shell in the front-back direction in a sealed mode. The two sides, in the front-back direction, of the pod shell extend outwards to be provided with a front shell and a rear shell respectively. The pod propeller and the ship comprise the propeller, the front shell and the rear shell are arranged on the two sides of the pod shell in the front-back direction respectively, and the structural strength and the anti-collision capacity of the underwater shell are improved. Even if the front shell and/or the rear shell are/is collided and damaged, the structural strength and water tightness of the pod shell and the propeller shell cannot be damaged, and the safety of the ship is improved.
本发明涉及推进器技术领域,尤其涉及一种水下壳体、吊舱推进器及船舶。水下壳体包括吊舱壳体、推进器外壳、前壳体和后壳体,吊舱壳体的顶部能够密封设置于船体上,吊舱壳体的底部连通设置有推进器外壳,螺旋桨的桨轴能够密封穿出推进器外壳沿前后方向的两端。吊舱壳体沿前后方向的两侧分别向外延伸设置有前壳体和后壳体。吊舱推进器及船舶包括上述的推进器,通过在吊舱壳体前后方向的两侧分别设置前壳体和后壳体,提高了水下壳体的结构强度和防碰撞能力。即使前壳体和/或后壳体发生碰撞破坏也不会对吊舱壳体和推进器外壳的结构强度和水密性造成损伤,提高了船舶的安全性。
