AI Technical Summary
Delamination is prone to occur at the root of wind turbine blades, resulting in insufficient structural strength and reduced service life. Existing mechanical reinforcement methods damage the original structure and are complex to construct, making them unsuitable for on-site reinforcement of in-service blades.
A bearing mechanism is fitted onto the outside or inside of the blade root, in conjunction with a circumferentially arranged adjustable clamping mechanism. Through circumferential encircling constraint and overall reinforcement, the blade root delamination and deformation are restricted. The clamping force can be adjusted as needed to avoid excessive local stress caused by rigid fixation.
It improves the structural strength and rigidity of the blade root, extends the service life of the blade, is suitable for on-site reinforcement of in-service blades, does not require damage to the original structure, is easy to construct, and is adaptable to complex working conditions.
