The invention discloses a safety elevator running in a fire disaster. The safety elevator comprises a building body, an elevator shaft is arranged in the building body, an elevator is arranged in theelevator shaft in a sliding manner, a lift car is arranged in the elevator, an airflow cavity is arranged in the bottom wall of the lift car, and a first driving shaft is rotationally arranged in thetop wall of the airflow cavity; and spiral fan blades are fixedly arranged at the lower end of the first driving shaft. According to the safety elevator, the safety elevator can be started when the fire disaster occurs, when the fire disaster occurs in a building, an elevator door is opened through a fire disaster alarm, smoke is used for providing power through a turbine, the situation that the elevator cannot be used due to power failures caused by the fire disaster is prevented, the smoke provides elevator door opening power through the spiral fan blades at the bottom of the elevator, elevator lifting power transmission is reversed through a pressing plate, and people are transported out, so that a fast, convenient and safe survival channel is effectively provided, and the survival rateof people is greatly increased.

    本发明公开了一种火灾时运行的安全电梯,包括建筑体,所述建筑体内设有电梯井,所述电梯井内滑动设有电梯,所述电梯内设有轿厢,所述轿厢底壁内设有气流腔,所述气流腔顶壁内转动设有第一驱动轴,所述第一驱动轴下端固定设有螺旋扇叶,本发明实现了火灾时启动的安全电梯,在建筑物内出现火灾时火灾报警器将电梯门打开,利用烟雾通过涡轮提供动力,防止因为火灾而导致的断电,使得电梯不能使用,烟雾通过电梯底部的螺旋扇叶提供电梯开门动力,再通过压板使得电梯提升动力传动反向,将人员运出,有效提供一种快速便捷且安全的求生通道,大大提高了人员的生存率。
