The utility model discloses a separating passive protective net, which comprises steel columns, a pedestal, an upper supporting rope, a lower supporting rope and a pulling steel wire. The pulling steel wire is fixed with adjacent components through U-shaped buckles, an upper end of each steel column is provided with a gap for penetration of the upper supporting rope, a gap for penetration of the lower supporting rope is formed between an upper supporting board and a lower supporting board of the pedestal, and a gap on the upper end of the steel column is formed by two parts with arc roofs facing inside. The separating passive protective net is reasonably designed, since the contacting parts of the upper end of the steel column and the upper supporting rope are of arc structures, the friction force between the upper supporting rope and the steel column during sliding can be effectively decreased, and the shift amount of the upper supporting rope is increased, when the protective net is subjected to large impac
