Abstract: A modular blade connection structure includes a first module, a second module and a structural adhesive module. The first module is provided on an end face thereof with a bonding flange extending into the second module; a gap between the butting surfaces of the first module and the second module is injected with a structural adhesive, which is extruded and cured to form a structural adhesive module; and the thickness of the first module at the starting end of the bonding flange extends towards the inner surface to form a first reinforcement, and the structural adhesive module extends inside the second module in a direction away from the bonding flange to form a second reinforcement. The present disclosure facilitates the control the bonding quality of the double-sided overlapping of the modular blade by means of the bonding flange and the improvement of the fatigue resistance at the assembling position.
