气垫式伸缩救生船的设计

摘要

气垫式伸缩救生船是在水灾发生后，为保证受灾人员能安全逃生而设计的逃生装置。它可以放在普通救生船上，在普通救生船载不完人的情况下，用于危急逃生；也可以放在家里，发生水灾时进行逃生。本文对气垫式伸缩救生船从机构设计、机构间的受力分析、以及船的浮力等方面进行了详细的研究计算。

首先，为了减小船身的体积，占的位置少，该船采用了伸缩机构。遇到水灾时，利用伸缩机构就可以很快的把船身打开，快捷而且方便。结构简单、抗风浪能力强、可折叠、便于携带。

其次，该船采用了气垫装置，在发生水灾时，利用充气泵给气垫充气完成后，船就可以用了。我们在研究过程中给出了相关机构详细的计算设计过程和图纸的详细标注。

再次，该船上的所有机构连接用螺栓或铆钉进行连接。

最后，本船实用新型体积小、成本低、使用方便，与救生圈相比，是一种既实用、又能提高求救者生存率的小型水上救生设备。

根据以上的理论计算，对气垫式伸缩救生船进行了模拟实验，取得了比较满意的结果。

Abstract

Air cushion type telescopic lifeboat is in a flood occurs, to ensure the affected people can safely and design of escape device. It can be placed in ordinary lifeboats, in the ordinary lifeboat years don't perfect conditions, used for emergency escape; Can also be put in the home, when a flood, escape. In this paper, air cushion type telescopic lifeboat from mechanism design, between organizations force analysis, and the ship's buoyancy and other aspects of the detailed study of calculation.

First, in order to reduce the volume of the hull, accounting for position less, the ship was adopted telescopic institutions measures. Meet flood, using telescopic institutions will soon open the hull, very convenient. Simple structure, resisting waves ability strong, but fold, easy to carry.

Secondly, the ship adopts the mattress device, occurred in flood, using aerating pump to mattress inflated after finishing, ship can use it. We are in the process of research presented related institutions detailed calculation of detailed drawings design process and labeling.

Again, the ship all institutions are connected with bolt connection.

Finally, this ship utility model small volume, low cost, easy to use, compared with life buoy, is a practical, and can enhance the survival rate for small water rescue equipment.

According to above the theoretical calculation of air cushion type telescopic lifeboat simulated experiment, and achieved satisfactory results.

Keywords: escape telescopic inflatable lifeboat
