[0002] With the development of the economic society, in recent years, the country has vigorously developed the wind power industry, and wind power generation has developed rapidly. The wind turbine tower barrel is an important part of wind power generation equipment. The technical difficulty of transporting a tower barrel dozens of meters or even hundreds of meters long is extremely high, and even difficult to achieve by ground transportation. Usually, a tower barrel with an axial length of dozens of meters or even hundreds of meters is limited by transportation conditions and needs to be axially split into multiple segments for transportation. After transportation to the wind farm, axial assembly and forming are carried out.

[0003] The segmented assembly structure of the wind turbine tower barrel is that corresponding inner folding flanges are arranged at the butt joints of adjacent tower barrel segments in the axial direction, so that several fastening bolts are used to axially lock and assemble adjacent tower barrel segments on the inner side of the tower barrel. When installing the tower barrel segments, it is often necessary to apply epoxy resin at the splicing joints (i.e., flanges) of the tower barrel segments to reduce the generation of cracks at the joints of the tower barrel segments and improve the tensile strength of the tower barrel.

[0004] However, currently, resin is usually applied manually at the flange. Due to the high height and large diameter of the tower barrel segments, the method of manual resin application seriously affects the installation efficiency of the tower barrel segments. Content of the Utility Model
