摘　　要：以安装在武汉的3kW聚光光伏电站为例,计算了其跟踪装置的风载,确定了跟踪装置中仰俯机构的高度角运行范围,选择太阳能推杆作为仰俯机构的执行机构,对其结构参数(如推杆固定角)和运动参数(如推杆行程、传动角和承受的拉力或压力)进行了推导、计算和分析,说明了仰俯机构的设计和推杆的选用要点。Taking the 3 kW concentrator photovoltaic（CPV） power plant located in Wuhan as an example, we have calculated the wind load of its tracker, determined by computation the range of altitude angle of the tracker＇ s pitching mechanism, and selected the solar pusher as the actuator of the pitching mechanism. The structural parameters, such as the location angle, and dynamical parameters, such as pusher stroke, drive angle and press or pull, of solar pusher in pitching mechanism were formulated, calculated and analyzed. The key points of design of pitching mechanism and selec- tion of pusher were illuminated.
