海流能发电机设计
摘 要
目前，国际性的能源危机和持续环境恶化使各国纷纷加大对可再生能源的开发力度。但随着人口增加等原因，可利用空余陆地面积急剧减少，人类已把目光转向海洋能源的开发利用。海洋能源是一种永不枯竭且无任何污染的“可再生性"能源。它是以潮汐、波浪、海流、温度差、盐度差等形式表达的物理、化学能量，为人类提供了大量宝贵能源。其中潮汐能、波浪能、温差能和盐差能的开发成本较高、发电效率相对低、规模开发利用难度大。
海流能是指海水流动的动能，其变化具有规律性，可预测性等特点。其成因是由太阳、地球及月亮相对位置及地球自转而引起的海水表层水平移动。我们选择了开发成本
相对较低，开发利用可行性较高的海流能做为研究对象，但海流能的利用在我国以及国际上都是一个崭新的课题。
在我国边远海域与沿海地区有为数众多电网无法覆盖的岛屿、哨所及村镇，那里的用电和淡水供应一直是个难题。如能利用每天持续不断的海流能提供电能和制备淡水所
需的能量，对于改善那里的生活条件不失为一种最现实的办法。海流能的利用要求整个发电装置浸泡在海水中，海流能发电机的工作环境决定了它所面临的难点，因此我们设想了一种新型的海流发电装置并制作了模型试图解决这些问题。关键词：海流能；海流模拟试验；海流能发电装置
Abstract
With the International energy crisis and the continued deterioration of the environment， Many countries increase the development of renewable energy today．However, with the population and other reasons，we can make use of the land area of sharp decline in spare． People have eyes to development and utilization of ocean energy．Ocean energy is a kind of renewable energy which is inexhaustible and no pollution．It is Physical and chemical energy expressed by Tides，waves，currents，temperature and salinity difference，and people Can obtain a lot of valuable energy from it．Tidal energy,wave energy,temperature energy and salinity energy can be bad to the development of high cost，relatively low efficiency of power generation，and the scale of the development and utilization of difficulty．
Currents can flow refers to the kinetic energy of water．It is caused by the sail，the relative positions of Earth and the moon and the earth’s rotation．We have chosen current energy which is the relatively low development costs，development and utilization of the high feasibility．But the exploit of Current energy is a new subject not only in China but also in the other countries．
There are many islands，post and villages in the remote sea areas and coastal areas， which are no power．And it is a problem about electricity and fresh water supply．If we can make use of daily continuous Current energy,it will be the most realistic way to improve their living conditions．Power devices immersed in seawater when We make use of Current energy, and the working environment of current energy generator determines the difficulties it faces． Therefore，we envisaged a new type of ocean current power generation devices and produced a model to deal with it．
Key words：Current energy；Current simulation test；Current generation devices
