The invention belongs to the technical field of safety protection, and particularly relates to a protective cover with high safety performance for
welding. The protective cover is characterized by comprising a protective cover body. By arranging a motor, a rotating shaft and rotating blades, in the
welding process, a worker carries out safety protection through the protective cover body, in the
welding process, the motor is started, the motor drives the rotating blades to rotate through the rotating shaft, and therefore sparks generated in the
welding process are blown to other places and prevented from splashing to goggles to cause accidents, meanwhile, mounting holes are formed in the rotating blades, flow limiting plates and compression plates are mounted on the inner walls of the mounting holes,
wind power is compressed and guided through the flow limiting plates and the compression plates, the
wind power collection range is wider, then the
wind power is discharged from shrinking through holes in connecting rings, the
potential energy of the wind power is improved, and therefore the wind blowing effect is improved; and it is ensured that te sparks generated in the
welding process cannot be sputtered to the protective cover body, and the protective effect of the protective cover is improved.
