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 3kW photovoltaic power station installed in Wuhan as an example, the wind load of the tracking device is calculated, the range of elevation angle of the pitch-up mechanism in the tracking device is determined, and the solar push rod is selected as the actuator of the pitch-up mechanism. The structural parameters (such as the fixed angle of the push rod) and the movement parameters (such as the push rod stroke, the driving angle and the tensile force or pressure) are deduced, calculated and analyzed, which shows the design of the pitching mechanism and the selection points of the push rod.
