Bridge guardrail with good anti-collision performance

The utility model belongs to the technical field of guardrails, and particularly relates to a bridge guardrail with good anti-collision performance, which comprises two upright posts, bases are fixedly welded at the lower ends of the two upright posts, positioning lugs are fixedly mounted at the left ends and the right ends of the two bases, and illuminating lamps are fixedly mounted in the middles of the upper ends of the two upright posts. Two transverse rods and a supporting plate are jointly and fixedly installed at the opposite ends of the two stand columns, the supporting plate is located between the two transverse rods, wind power generation mechanisms are fixedly installed on the upper portions of the sides, away from the opposite ends, of the two stand columns, and the wind power generation mechanisms are electrically connected with the illuminating lamps on the same sides. Impact force generated during collision is reduced through compression of the buffer springs, the buffer plate is buffered, the
