Vibration oil cylinder protection device and protection method thereof

The invention discloses a vibration oil cylinder protection device and a protection method thereof, and belongs to the technical field of vibration oil cylinder protection. The device comprises a vibration oil cylinder, a piston rod output shaft is arranged at the output end of the vibration oil cylinder, a sealing ring is arranged on the outer ring of the piston rod output shaft, the output end of the piston rod output shaft is connected with a connecting shaft, and a static guide cover and a dynamic protective cover are arranged on the surface of the vibration oil cylinder. The mechanical seal dynamic and static ring principle is adopted, and sealing protection is achieved through the design of the static guide cover and the dynamic protective cover; the static guide cover adopts a water flow condensation pipe design to reduce the environment temperature of the output part of the piston rod; the dynamic protective cover adopts an air cooling and airflow curtain design, so that the dynamic protective cover i
