Magnetic damping life-saving apparatus

Abstract

The invention is a magnetic damping life apparatus which includes shell, spool, insurance ropes and driving device. The spool support on the shell through rotation shaft, one end of insurance ropes is fixed and wound on the spools. Said magnetic damping life apparatus also includes electrical and mechanical conversion device and energy receiving device, the spool drives the electrical and mechanical conversion device through the driving device, electrical and mechanical conversion device transforms the mechanical energy into electrical energy which is received by the receiving device to increasing the safety and practicality of magnetic damping life apparatus.

Description

【Technical field】 [0001] The invention relates to a life-saving device, which can be used as self-rescue and escape equipment for trapped people when disasters occur in construction disasters (fires, earthquakes, terrorist incidents, etc.), warships and passenger and cargo ocean-going ships. Simultaneously, the magnetic damping life preserver of the present invention can also be used as a kind of safety equipment for cleaning personnel on the exterior wall of a building. 【Background technique】 [0002] Among many natural disasters, earthquakes and fires are the most sudden, and they cause the greatest casualties to human beings. For civil self-rescue equipment in the event of a disaster in high-rise buildings, due to the particularity of its use, use environment, storage time and other conditions, there are extremely high requirements for the practicability and safety of life-saving equipment. But existing life-saving equipment for high-rise buildings is limited by the mech...

AI Technical Summary

Problems solved by technology

However, the existing life-saving equipment for high-rise buildings is limited by the principle of mechanical friction, and the structural design cannot guarantee safety and practicality. When a disaster occurs, it is difficult for rescuers to rescue the trapped people in high-rise buildings in time.

The main disadvantages of its existence are: 1. It adopts friction brake, which has few times of use, poor reliability and safety, and can only be used by professional firefighters, and is not suitable for civilian self-rescue.

2. The descending speed cannot be adjusted. The descending speed is fast when the human body is heavy, and the descending is slow when the human body is light. It is not conducive to crossing the fire layer and emergency escape of children, and it cannot stop in the air as needed.

5. When in use, the safety ropes at both ends move relative to each other within a few centimeters, and the relative movement speed can reach 3m / s, so the user is extremely vulnerable to injury

6. The use height is limited (below 100M)

Because friction generates heat, it is usually easy to stall when used at a height of more than 50 meters

7 When in use, the two safety ropes move relative to each other, which is very easy to cause injury

8. The host and the safety rope are separated into two pieces, which is inconvenient to use and operate
