Abstract
Disclosed is a novel photovoltaic-panel two-dimension-motion control system driven by a single motor. The system includes a PLC installed in a control box. The PLC controls a solar-hour-angle tracking mechanism. The solar-hour-angle tracking mechanism is a rotation mechanism which is parallel to the rotation axis of the earth. The solar-hour-angle tracking mechanism includes a stepping motor. An output shaft of the stepping motor is connected with a speed reducer. An output shaft of the speed reducer is connected with a driving shaft parallel to the rotation axis of the earth. A photovoltaic panel is installed on the driving shaft. A rotation nut push block used for driving a rotation nut to rotate is also installed at the end part of the driving shaft. A lifting screw is installed in an internal threaded hole of the rotation nut in an engaging manner. The top end of the lifting screw is installed at one side of the bottom part of the photovoltaic panel. The PLC is also connected with a coder in which the motion frequency of the stepping motor is stored. A power amplifier is connected between the coder and the stepping motor. In the photovoltaic-panel two-dimension-motion control system driven by the single motor, the rotation nut of the pitching mechanism is driven to rotate while the driving rotation is rotating so that the lifting screw supports the pitching of the photovoltaic panel in an ascending and descending manner.
