When wind turbine blades reach the end of their service life or are no longer suitable for use, they need to be recycled. The current method of processing wind turbine blades is mainly to cut the wind turbine blades into small pieces, cut the small wind turbine blades into small pieces, and crush them into fragments or powder through crushing equipment;

[0003] For example, "CN114406351B" discloses a recycling device and method for discarded wind turbine blades, wherein the recycling device for discarded wind turbine blades includes a longitudinal moving mechanism, a blade clamping device, a rope saw transverse moving mechanism and a rope saw main structure, wherein the blade clamping device is arranged on the longitudinal moving mechanism, the rope saw main structure is installed on the corresponding rope saw transverse moving mechanism, the rope saw transverse moving mechanism is symmetrically arranged at the front end of the longitudinal moving mechanism, the blade clamping device includes a blade root clamping mechanism, the blade root clamping mechanism includes an annular fixed track relatively fixed to the longitudinal moving platform and a blade root clamping mechanism moving along the annular fixed track, the transverse moving platform is sequentially provided with a guide wheel bracket, a tightening transverse moving mechanism and a rope saw main unit from the inside to the outside, the tightening transverse moving mechanism is used to drive the tightening wheel to move transversely, and the guide wheel bracket includes an arc beam and a guide wheel structure installed on the front side of the arc beam. The present invention uses one device to cut the entire wind turbine blade in sections, has high working efficiency, and the blades are not easily deformed, thereby reducing safety risks;

[0004] However, in the prior art, as shown in the above patent, the cutting effect of wind turbine blades is very good, but there is a lack of protective measures during the cutting process, and the main components of wind turbine blades are glass fiber, carbon fiber and epoxy resin, among which the glass limiter is relatively small. The glass limiter debris during cutting will fly around and come into contact with the skin of surrounding workers, causing damage to the eyes or skin. It will also be inhaled into the body during breathing, causing respiratory damage. The output of glass fiber and other debris generated by cutting a wind turbine blade is very large. If it cannot be intercepted and processed at the source, it will greatly affect the health of surrounding workers and other personnel. Summary of the invention
