Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a power generation device and a power generation system. Background Art

[0002] A tower crane is a rotating crane with a boom mounted on top of a tower. It is primarily used for transporting materials and lifting components during the construction of multi-story and high-rise buildings. However, in remote areas or areas affected by earthquakes, mudslides, and other disasters, tower cranes are often unusable due to power outages, which reduces construction efficiency. Furthermore, tower cranes consume a lot of electricity, resulting in high electricity costs.

[0003] Conventional technology uses photovoltaic panels installed on the boom of a tower crane to generate electricity, allowing the crane to generate its own electricity. This allows the crane to operate normally in areas without power systems and reduces the crane's electricity costs. However, when installing photovoltaic panels, multiple panels are typically connected in series and then connected to an inverter. This results in the installation and removal of each panel being affected by the other panels. Adding or removing a panel requires adjusting the positions of the other panels, making installation and removal inconvenient. Summary of the Invention
