The invention relates to a magnetic levitation bearing system, in particular to a manual type bearing protection device. The manual type bearing protection device comprises a rotor, two bearing seats,two groups of bearing protection assemblies and a manual driving assembly; two ends of the rotor are in a circular truncated cone shape; the two bearing seats are arranged at the two ends of the rotor, and the two ends of the rotor extend into the bearing seats; the two groups of the bearing protection assemblies are symmetrically and slidably arranged in the bearing seats, cone-shaped holes which are matched with the ends of the rotor are formed in the bearing protection assemblies; and the manual driving assembly drives the bearing protection assemblies to axially move close to each other until the bearing protection assemblies are in contact with the rotor. The manual type bearing protection device can temporarily support the rotor when a magnetic bearing system fails, can manually protect the rotor, prevents damage caused by falling of the high-speed rotor, and improves the security of the system.
