The walking mechanism includes a connecting plate 1, a driving wheel assembly 2, and two auxiliary wheel assemblies 3. The connecting plate 1 is connected to the base 100. The driving wheel assembly 2 is arranged in the middle region of the connecting plate 1. The two auxiliary wheel assemblies 3 are connected to the connecting plate 1 and arranged on the two sides of the driving wheel assembly 2. In this way, the overall structure of the walking mechanism is stable, and the walking mechanism can move more stably on the steel strand 102. The auxiliary wheel assembly 3 is arranged on the two sides of the driving wheel assembly 2 to further improve the stability of the walking mechanism during the turning process between the two photovoltaic modules 101.
