AI Technical Summary
The existing wind turbine tower flange connection bolts pose a risk of accidental snagging during climbing, resulting in safety hazards. Furthermore, the existing protective equipment cannot simultaneously ensure both surface smoothness and protective effectiveness.
Design a protective device that includes a protective shell, mounting base, cover shell, sealing mechanism, reinforcing components and locking mechanism. The bolt protection is achieved by using a three-layer composite material (high-strength alloy steel, rubber and EPDM sealing material) combined with a spring and insert structure to ensure a smooth surface and excellent protective effect.
It improves climbing safety, reduces the risk of accidental snags, enhances the protective effect of bolts, reduces the number of maintenance visits, and lowers maintenance costs.
