Abstract

The invention relates to the technical field of solar tracking devices, and provides a novel biaxial photovoltaic tracker comprising a base and a biaxial tracking mechanism. The base comprises a fixediron plate and a fixed gear. The fixed gear is welded on the fixed iron plate. In the biaxial tracking mechanism, the four side surfaces of a photovoltaic panel fixing plate are provided with photoresistor mounting blocks, and each photoresistor is arranged on one photoresistor mounting block. The left side of the photovoltaic panel fixing plate is connected with a left side frame through a firstconnecting rotation shaft. The rotor of an upper stepping motor is connected with the first connecting rotation shaft or a second connecting rotation shaft. The fixed gear is connected with a lower frame through a third connecting rotation shaft on the upper part. A lower stepping motor is mounted on the lower frame. A moving gear is fixed on the rotor of the lower stepping motor. The moving gearis meshed with the fixed gear. The photoresistors, the upper stepping motor and the lower stepping motor are all electrically connected with a controller. The pitch angle and the azimuth angle of thephotovoltaic panel can be adjusted in real time so that the photovoltaic power generation efficiency can be improved and the novel biaxial photovoltaic tracker is suitable for small photovoltaic power stations.

Description

technical field [0001] The invention relates to the technical field of sun tracking devices, in particular to a novel dual-axis photovoltaic tracker. Background technique [0002] Vigorously developing renewable energy is one of the effective ways to deal with the fossil energy crisis and environmental problems. Among them, photovoltaic power generation has developed rapidly in recent years due to its advantages of abundant resources and little influence by geographical location. The output of photovoltaic power generation is closely related to the intensity of sunlight. Common ground photovoltaic systems generally use concrete as the installation foundation for solar photovoltaic support. However, due to the rotation and revolution of the earth, compared with a solar photovoltaic power generation system at a fixed location, the In the four seasons of summer, autumn and winter, the sun rises and sets every day, and the angle of the sun's light changes all the time. This effe...
