坐海底波能摆式发电机构设计(中文3700字,英文2300字)
摘 要：海洋能作为一种清洁的可再生能源，利用其进行发电的装置研究越来越受到人们的重视。波浪能作为海洋能的一种,是指海洋表面波浪所具有的动能和势能。它是海洋中蕴藏最为丰富的能源之一,也是海洋能利用研究中近期研究得较多的能源之一。国内外众多机构已经研究出多种形式的波浪能转化装置，但由于这些转化装置普遍存在着转换效率偏低的问题，成为大规模推广应用的障碍之一。在综合分析已有装置的基础上，设计出一种能有效提高波浪能利用的摆式波浪能转化发电装置机构。该装置的原理：其主体是随着波浪摆动的摆体，摆体是摆式装置的一级能量转换机构。在波浪的作用下，摆体作左右摆动,将波浪能转换成摆体的动能。与摆体相联的通常是一套液压装置，它将摆体的动能转换成液压装置的动能，再带动发电机发电。摆体的运动很适合波浪大推力和低频的特性，因此摆式装置的转换效率较高,但机械和液压机构的维护较为困难。摆式装置的另一优点是可以方便地与相位控制技术相结合，相位控制技术可以使波浪能装置吸收迎波宽度以外的波浪能，从而大大提高装置的效率。

Abstract: as a kind of clean and renewable energy, the marine energy is more and more valued by people. Wave energy as a kind of ocean energy is the kinetic energy and potential energy of ocean surface waves. It is one of the most abundant sources of energy in the ocean, and it is also one of the most recent studies in the study of ocean energy utilization. Many types of wave energy conversion devices have been studied at home and abroad. However, due to the low conversion efficiency of these devices, it has become one of the obstacles to large-scale application. On the basis of comprehensive analysis of the existing device, design a can effectively improve the utilization of wave energy of pendulum wave energy conversion device power mechanism. The principle of the device: the main body is with the pendulum waving, the pendulum is an energy conversion mechanism tilting device. Under the action of the wave, the pendulum swing is left and right, and the wave energy can be converted into the kinetic energy of the swing body. A hydraulic device is usually connected with the pendulum body, which converts the kinetic energy of the pendulum body to the kinetic energy of the hydraulic device, and then drives the generator to generate electricity. Pendulum body of the game is suitable for wave high thrust and low frequency characteristics, so tilting device conversion efficiency was higher, but the maintenance of mechanical and hydraulic mechanism is difficult. Tilting device of another advantage is that it can easily and phase control technology combining, phase control technology can make wave energy device to absorb the wave width of attack outside the wave energy, so as to greatly improve the device efficiency.
