Wind power generation has become an indispensable renewable energy source. However, wind turbine blades fail in harsh environments such as ultraviolet radiation, ice, temperature changes, and dirt. Therefore, wind turbine blades need to be regularly repaired. In view of the difficulty of wind turbine blade repair, the current wind turbine blade maintenance methods and defects are analyzed, and a new robot mechanism that can crawl on the wind tower and detect the wind turbine blades is proposed. The mechanism adopts a permanent magnet adsorption mechanism, which can be stably adsorbed on the wall surface of the wind power tower barrel and move on the wall surface, and can adjust the arm extension length according to the distance between the wind power blade and the tower barrel, so as to detect the wind power blade. Using Solidworks, AnsysMaxwell ,Adams and other software to carry out structural modeling of the robot and simulation of the adsorption mechanism, movement simulation. The robot is subjected to force analysis under different instability conditions to obtain the required adsorption force, and the simulation results are compared with the calculation results. The research results show that the wall-climbing robot's adsorption capacity meets the adsorption requirements, and it can be stably adsorbed on the wind power tower and detect the wind power blades.
