Abstract: An upright-plate type sunlight generator comprises up-right-plate type photovoltaic generating tubes capable of automatically cleaning dust, collecting mirrors with the automatic storm-sheltering mechanisms and a collecting carrier, a cooling and radiating system, and an automatic sun-tracking machine and its object carrier. The collecting mirrors are the folding mirrors made up of plane mirrors, and are connected to the photovoltaic generating tubes provided in the focal strip of the group of collecting mirrors during the operation on the support of the collecting carrier. The collecting carrier is immovably connected to the object carrier of the automatic sun-tracking machine, and the object carrier is connected to the automatic sun-tracking machine. The cooling and radiating system includes a liquid-cooling cavity that is the internal cavity of the photovoltaic generating tube, flexible connecting pipes and a liquid storing and cooling member.
