Air bag blade tip maintenance method of wind power blade

The invention discloses an air bag blade tip maintenance method for a wind power blade in the field of design and manufacture of wind driven generator blades, which comprises the following steps of: taking an evidence through camera shooting, determining a blade damage position by combining a design drawing of a fan blade and a position of blade navigation mark paint, and then determining a cutting position of the blade; and then segmented air bag blade tips are manufactured through the 3D printing technology, then the segmented air bag blade tips are firmly bonded, and finally the air bag blade tips are installed on the blade body under the appropriate meteorological condition. According to the air bag blade tip maintenance method, a longer blade body is reserved, meanwhile, broken objects generated by blade breakage are removed, damage to the air bag blade tip is avoided, the strength of the air bag blade tip is guaranteed, meanwhile, the surface of the air bag blade tip is polished to be smooth, and the wi
