| 摘 要：太阳能作为纯净的能源，既是一次能源，又是可再生的能源，有着化石能源无法相提并论的优越性。但太阳能利用效率低和有这局限性这些问题一直阻碍着太阳能技术的发展。而把太阳能运用到军事机械更是必须攻克的难题。设计精确的太阳能板收展机构，可使太阳能采光板的采光率大大的提高，对与提高太阳能利用的效率大大提高，有利于拓宽太阳能的利用领域。在太阳能的工作中，电池板受光面与太阳光线的角度是决定太阳能发电效率的非常关键的因素。装配式野战车如果装上了太阳能板的收展执行机构，就可以在战场上大大的节约能源，从而有可能是我军赢得胜利的关键因素。28992 为了能更好的接受阳光的光线，本设计提出了凸轮机构，和蜗轮蜗杆机构来解决接受光线的角度为题。运用这两个机构来调整太阳光照射角以极高太阳能电池的光电转化率。该系统内部由步进电机工作来实现使太阳能电池板一直处于垂直于太阳光线的角度，来提高太阳能的利用率。由于时间和目前的知识限制，只是进行粗略的角度调整，有较大误差，今后如有机会再进行改进。 毕业论文关键字：太阳能板收展机构；太阳照射角；凸轮机构；蜗轮蜗杆；步进电机 Design of Prefabricated field power cars for Or closed institutions Abstract: Solar energy as pure energy, both primary energy, and renewable energy, fossil fuels can not be equated with superiority.But the low efficiency of solar energy utilization and limitations of these problems have been that hinder the development of solar technology.The solar energy applied to the military machinery is necessary to overcome the problem.Design accurate solar panels or closed institutions, can lighting of the solar lighting panels greatly improved, and improving the efficiency of solar energy utilization is greatly improved, help broaden the field of solar energy utilization.Work in solar energy, solar panels light-receiving surface and the angle of the sun's rays are very crucial factor in determining the efficiency of solar power. Prefabricated field car if fitted with solar panels or closed actuators, it can greatly save energy on the battlefield, so there may be a key factor in our army to victory. In order to better accept the sun light, the design of the cam mechanism is proposed, and the worm mechanism to address the theme of acceptance angle of light. The use of these two institutions to adjust the angle of the sun light at very high photoelectric conversion rate of solar cells. The system consists of an internal stepper motor to achieve the solar cell panel has been in a perpendicular angle to the sun's rays, to improve the utilization of solar energy. Due to time limitations and the current knowledge, only a rough angle adjustment, there is a large error in the future if the opportunity to make improvements.
