1、湖面清洁机结构设计摘 要：本文主要是对水面（主要是公园的湖面）垃圾自动打捞船的船体结构、动力装置、传输装置、垃圾存储装置以及其他零部件的设计、计算、校核等。此外，在了解此次设计的成果所需实现的功能需求，以及实际环境背景的情况下，研究湖面清洁机结构构成及功能的设计方法。湖面清洁机针对水面环境污染的问题，致力于中小型公园湖面的固体垃圾（如树 叶，塑料袋，瓶子等）清理，可以实现湖面垃圾清理的机械化与自动化，整个打捞过程无需人工参与，安全性非常好，效率大约是人工打捞的几十倍。为了使得湖面垃圾的收集更加有效率，特意采用链齿轮与链条的传动带动传输带的形式，以及船体前方叶轮的设计。此外，为了便于湖面垃圾的清
2、理，垃圾存储装置采用的是三个可替换式的存储箱，其底部设计为多孔式。关键词：湖面垃圾,自动清理,环境保护,船舶,高效率The lake cleaning machine structure designAbstract：This paper aims at designing, calculating and collating the hull structure, powerplant, transmission device, garbage storage device as well as other parts of the automaticlake-cleaning machin
