From the above structure, it can be seen that the fixing frame 1 plays a role of connecting the telescopic maintenance ladder 2 and the climbing support assembly at the same time and fixing the positions between the telescopic maintenance ladder 2 and the climbing support assembly. The telescopic maintenance ladder 2 is inclined at the top of the fixing frame 1 and extends to the lower left of the fixing frame 1. After installation, the telescopic maintenance ladder 2 is suspended above the solar panels. The telescopic maintenance ladder 2 includes a number of telescopic maintenance ladder units with different sizes and sleeved in sequence from large to small, which is convenient for adjusting the extension length of the telescopic maintenance ladder 2 according to the actual position of the maintenance. The climbing support assembly is arranged at the bottom of the fixing frame 1 for supporting the fixing frame 1 and facilitating the staff to climb from the climbing support assembly to the telescopic maintenance ladder 2.
