fall protection device

Abstract

The invention relates to a high-altitude fall protection device, which includes a three-axis acceleration sensor, a main control circuit, an ignition drive circuit, an igniter, a gas generator and a safety airbag, wherein the three-axis acceleration sensor detects acceleration and transmits the acceleration signal to the main engine. Control circuit; the main control circuit receives the acceleration signal and sends the ignition enable signal to the ignition drive circuit; the ignition drive circuit receives the ignition enable signal and sends drive power to the igniter; the igniter is built into the gas generator and can detonate the gas generator The ignition agent in the gas generator; the gas generator is filled with the ignition agent and the gas generating agent, and the outlet of the gas generator is connected with the safety air bag; the safety air bag includes more than one safety air bag, each safety air bag is folded and curled in a backpack, and the backpack is opened There are air bag ejection openings for each air bag ejection. The invention has the advantages of simple structure and convenient use, can effectively reduce the damage caused by falling from high altitudes, and guarantee the safety of personnel working at high altitudes.

Description

technical field [0001] The invention relates to the field of safety protection for high-altitude operations, in particular to a high-altitude fall protection device. Background technique [0002] Personnel working at heights such as power pole tower climbers, high-rise construction personnel, building cleaning personnel, and outdoor climbing and rock climbing personnel all need to undergo formal training and strictly abide by high-altitude safety operation procedures. At the same time, they must wear a variety of safety protection equipment during the operation . Nevertheless, due to personnel negligence or equipment damage, there is still a certain risk of falling for personnel working at heights. In addition, the current high-rise buildings are gradually increasing, and people spend most of their time in high-rise buildings. Once a fire breaks out in a high-rise building, people will be trapped in the high-rise building, and the smoke generated by the fire will force peop...

However, due to personnel negligence or equipment damage, there is still a certain risk of falling for personnel working at heights

In addition, the current high-rise buildings are gradually increasing, and people spend most of their time in high-rise buildings. Once a fire breaks out in a high-rise building, people will be trapped in the high-rise building, and the smoke generated by the fire will force people to the balcony and window. The window is waiting for rescue, in an emergency, it is prone to fall accidents
