Abstract

本发明轮船的转向机构的改进方案，其特点是控制轮船的航行方向不靠尾舵，而是在轮船的前部和后部船舷的吃水线下，左右各安放一个螺旋桨，这样可以快速地转向。

Description

轮船转向机构的改进方案
技术领域
本实用新型轮船转向机构的改进方案，系一种普通造船业里的一项重大改革。
背景技术
轮船在水中航行时，为了避免撞上暗礁、或是钻过桥洞、躲避来往船只、以至最后傍靠码头时，都时不时地需要变换航行方向，方能平安地行驶、通过。过去一向是依靠船尾的一个方向舵来扭动船身以改变航向的。但是由于一般尾舵的尺寸与船身的长度相较，非常有限；而且转向的效率又是随着水流相对于船身航行的速度成直线变化，因此当船行速度下降时，转弯效率就会大大降低，以至于尾舵此时根本起不了作用，当轮船要进入码头时，就会使舵手深感棘手。尤其是在雾天航行时，要经常避让来往船只，由于明视距离有限，因而当两船相离很近时往往避让不及而酿成惨祸，这在世界航海史上是屡见不鲜的。
百年前泰坦尼克号巨型邮轮上1500多名旅客的葬身海底，就是当年的总设计师托马斯·安德鲁斯(TOmas Andrews)的设计失误所造成的悲剧。可见，工程设计上哪怕是“小小的”失误，就会造成人类生命和财产多大的损失！若是此项发明早一百年前就诞生，这一百年间所发生的多少起海难历史就可以改写！
发明内容
此项发明，就是为了解决这个基本矛盾而设计出的新的转向方法，即设法横向给力，它所产生的扭距，大大高过尾舵所产生的扭矩，以增大扭转船身的扭力，其转向效率更是与轮船的航速无关。
办法是，在轮船左右船舷的前端和尾端的吃水线下，各安上一个螺旋桨，当要转向时，开动对角线上的两个螺旋桨，便可轻易地转动船身，甚至还可以原地打转，这对于进港靠码头的船只，尤为有利，因为此时可以同时开启一侧的螺旋桨，以使船身慢慢地贴近码头！
附图说明

A——螺旋桨
具体实施措施
1、改造现有船只：
利用现有的船只，在其前后左右船舷吃水线下的合适部位，开四个洞，内各装一个螺旋桨，并用活动盖板遮盖，以防海水进入。
2、造新船时，在船舷的吃水线下的合适部位，预留四个洞，以备安装螺旋桨用。

Claims (2)

1.本发明轮船的转向机构，其特点是控制轮船的航行方向不靠尾舵。
2.根据权利要求1所述，在轮船的前部和后部船舷的吃水线下，左右各安放一个螺旋桨。
