摘  要
在环境污染和能源短缺等问题日趋严重的背景下，开发水能、风能、太阳能等可再生能源成为人类迫切的需要。目前太阳能热水器的使用已经得到广泛普及，但是这种方式虽然节约了能源却不能从根本上解决能源短缺问题。利用太阳能发电是解决当前能源、资源和环境等问题的一种有效途径和方法。
目前，较为成熟的太阳能发电技术是光伏发电和太阳能热发电。在太阳能热发电中，通过聚光产生高温进而发电的效率较高，更具应用前景。聚光类太阳能热发电有塔式、槽式、碟式三种。其中，槽式太阳能热发电系统结构紧凑，其太阳能热辐射收集装置占地面积比塔式和碟式系统的要小30％～50％；且槽形抛物面集热装置的制造所需的构件形式不多，容易实现标准化，适合批量生产；用于聚焦太阳光的抛物面聚光器加工简单，制造成本较低，耗材少等一系列优点，因而成为了人们研究的焦点。
本文主要针对常见槽式太阳能热发电系统的集热器进行总体设计和分析。在设计过程中主要以动力传动路径为依据来进行各零部件的设计。首先根据太阳能集热器的工况要求初选一比较合适的步进电机，接着根据已知条件选择一合适的单级蜗轮蜗杆减速器，并通过计算校核确定其是否真的满足条件。对于销齿传动部分，需要根据传动比等条件进行严格的计算校核，并根据最后得出的数据进行零件加工。最后是聚光器的设计，其中聚光器包括反射镜和支架，这部分主要采用的是常见且加工生产技术成熟的设计方案。计算完成设计数据之后,再根据数据绘制出各主要零部件的CAD图纸以及Pro-E零件图、装配图，并进行运动仿真模拟。通过本次毕业设计，使我对槽式太阳能集热器的工作原理、性能特点有了基本的了解，同时也熟悉了太阳能集热器总体设计的基本步骤和方法，综合运用在《机械原理》、《机械设计》等课程中所学的知识，理论联系实际，拓宽、加深所学专业知识，提高自己的综合素质。总之，在本次毕业设计中我学到了很多，受益匪浅。这将为我以后从事相关方面的研究、工作打下坚实的基础。 [资料来源：Doc163.com]

The overall design of trough solar collector
Abstract
    On the backdrop of Environmental pollution and energy shortages, the development of hydro, wind, solar and other renewable energy has become urgent needs to human. Currently the use of solar water heaters have gained wide popularity, but this approach, while saving energy but not fundamentally solve the problem of energy shortage. Use of solar power is the solution to the current energy, resources and environmental issues is an effective way and methods.
    Currently, more mature solar power technology for photovoltaic and solar thermal power generation. In solar thermal power generation, through the condenser generate heat and thus a higher efficiency of electricity generation and more applications. There are three kinds of solar thermal power generation system . Among them, the trough solar thermal power generation system is compact, its solar thermal radiation collection device footprint than the tower and dish systems to be smaller 30% to 50%;and parabolic trough collector device manufacturing components required form small,easy to implement standardization, suitable for mass production; sunlight for focusing parabolic concentrator processing simple, lower manufacturing costs, less supplies a series of advantages, and thus become the focus of people's studies.

    In this paper, common trough solar thermal collector overall power generation system was designed and analyzed. Mainly in the design process is based on the power transmission path for all parts of the design. First, according to solar collectors working conditions primaries a more appropriate stepper motor, then select a suitable under known conditions of single-stage worm gear reducer and checked by calculating determine whether it satisfies the condition. For the pin gear transmission parts, gear ratio and other conditions required under strict checking calculations and derived data based on the last part machining. Finally, the design of the condenser, where condenser includes a mirror and bracket, which is used in some of the major common and processing technology is mature design. After the calculations are complete design data, according to the above data to draw all the major parts of the CAD drawing and Pro-E part and assembly drawings and simulation exercise. Through this graduation project so that we are familiar with the overall design of solar collectors the basic steps and methods, integrated use of "mechanical principle", "Mechanical Design" courses, theory with practice, to broaden and deepen knowledge of the profession, improve my overall quality. In short, through this design, I learned a lot which will be engaged in relevant aspects of my future research work has laid a solid foundation. [资料来源：http://www.doc163.com]
