High-rise electromagnetic damping escape device

Abstract

The invention discloses a high-rise electromagnetic damping escape device. The device comprises a rescue cabin module, a speed change wheel module and a magnetic damping speed reducing piston module;the rescue cabin module comprises a left side escape well and a right side escape well, a left side escape cabin, a right side escape cabin, and buffer pads arranged at the bottoms of the escape wells; the speed change wheel module comprises a double-rail rope wheel, a rope wheel center shaft, a speed change large gear, a speed change small gear, a cam and a rope; and the magnetic damping speed reducing piston module comprises a cam connecting rod, a magnet, a copper pipe and a protective cover. The magnet performs a reciprocating motion in the copper pipe; as the continuous change of the magnetic flux can be caused by the reciprocating motion of the magnet in the copper pipe, induction current can be generated on the copper pipe by the Faraday law; through the Lenz law, the generated induction current can be associated with an induction magnetic field to act on the magnet; and the descending speed of the rescue cabin can be reduced by using resistance continuously generated by the electromagnetic induction phenomenon in less space.

Description

technical field [0001] The present invention relates to the technical field of escape equipment, and more specifically relates to an electromagnetic damping escape device for high-rise buildings. Background technique [0002] With the rapid advancement of urbanization and the rapid increase of urban population, in order to meet the needs of living and office, the height of buildings is increasing day by day. When facing critical situations such as fire, high buildings often cause serious casualties due to the lack of effective means of escape. Therefore, more and more society pays close attention to for the research of high-rise escape device. At present, the common high-rise escape devices on the market mainly use self-rescue emergency ropes of descending devices, life-saving air cushions, life-saving slides and other equipment. The self-rescue emergency rope needs to be fixed manually during use, and the position of the rope needs to be constantly adjusted during the des...

AI Technical Summary

Problems solved by technology

The self-rescue emergency rope needs to be fixed manually during use, and the position of the rope needs to be adjusted continuously during the descent process. Due to the complicated operation, the elderly and children cannot use it alone, and it is easy to cause secondary injuries to the shoulder and neck when descending

Rescue air cushion is a kind of inflatable air cushion, because it cannot reach the fire scene quickly and put into use, a lot of rescue time is wasted, and it is limited to lower floors

Although the lifesaving slide can be used by the elderly and children, its safety is relatively low because its rescue principle relies on the inner guide sleeve material and is easily scratched
