摘　　要：针对光伏板发电量受其表面灰尘影响较大及大型光伏电站光伏板清洗难度大的现象,提出了新型光伏组件自动清洗机的设计构想。光伏组件均有一定的安装角度,设计结合了真空吸附技术、履带驱动技术,保证清洗机能够在倾斜的表面上自由移动。考虑到我国西北地区大型光伏电站所处风沙较大、人力资源匮乏、干旱少雨等特殊环境,提出三步清洗法,保证清洗机高效地完成光伏组件的清洗任务。理论计算结果表明该设计是完全可以实现的,且在原理性验证试验中清洗效果较好,达到预定要求。The generation capacity of the photovoltaic （PV） panels is influenced by dust on the surface, and it is difficult to clean the PV panels of large scale PV power station, thus the design concept of new type of automatic cleaning machine for PV modules is proposed. Due to PV modules are installing in certain angle, the design combines vacuum adsorption technology and crawler drive technology, to ensure the cleaning machine moving freely on inclined surfaces. Considering the particular environment in which the large scale PV power stations located, e. g. , heavy wind and sand,lack of human resources, and drought, etc. , the three-step cleaning method is proposed for ensuring the cleaning machine completes the cleaning task in high efficiency. The results of theoretical calculation show that the design is fully implemented, and the cleaning effect is better in verification test of principium, and reaches the predetermined requirements.
