[0002] With the rapid development of society, the excessive use of resources has caused serious pollution to the environment. The international community has attached increasing importance to energy conservation and emission reduction, calling for the use of green energy to replace traditional energy to reduce pollution to the environment. In recent years, the use of solar energy has made significant progress. Solar photovoltaic panels are currently the most common devices for converting solar energy. As a clean and environmentally friendly green energy product, solar photovoltaic panels are increasingly used in various fields of production and life. Solar photovoltaic panels are connected to grid-connected photovoltaic power generation systems or independent photovoltaic power generation systems. When the flat single-axis bracket is tracking the sun normally, a driving device is required to drive the photovoltaic components to rotate from east to west with the north-south axis as the axis to obtain higher sunlight irradiation and increase power generation.

[0003] The photovoltaic tracking brackets currently on the market are limited by the adverse effects of undulating terrain on installation and are mostly used in relatively flat terrain. When the terrain is basically flat or a large area of ​​sloping terrain, the axis of rotation of the tracking bracket is basically parallel to the ground. However, when encountering relatively dense undulating mountains, it is difficult for a long single set of tracking brackets to be installed continuously along the slope.

[0004] For a mountain photovoltaic project, the size of the mountain slope is often more complicated, not a single slope. The existing flat single-axis tracking bracket needs to be designed one by one according to the different slopes of the mountain to meet the on-site installation requirements. The design workload and on-site installation workload are both very large. Utility Model Content
