Background
At present, emergency escape equipment is applied to a plurality of disaster scenes, including daily life places such as hotels and restaurants and special operation places such as elevator shafts, sewage shafts and other closed spaces. For example, when a fire disaster occurs, toxic gas diffuses and high temperature damages a human body, and by wearing the protective clothing, the damage to the human body can be effectively reduced, and meanwhile, sufficient escape time is obtained. Similarly, the closed space is a common space type in modern production and life, and due to the narrow space, accidents are easy to happen, and the space is not beneficial to rescue.
Statistical data show that the number of casualties caused by personnel failing to escape in time and improper rescue exceeds more than 90 percent of the total casualties. Therefore, whether a person can escape quickly when an accident occurs is related to the severity of the accident consequence. If the personnel can be timely separated from the dangerous scene, subsequent rescue is not needed, and casualties caused by improper rescue can be reduced to the minimum degree.
The existing emergency protection equipment mainly focuses on protecting the safety of a human body, such as positive pressure air equipment, breathing appliances such as a long pipe mask and the like, and an elevator shaft anti-falling construction operation frame. These devices, although they protect the safety of the workers' lives to the greatest extent, do not help them to leave the enclosed space and have a limited protection time.

the method comprises the following steps: the working states of the mask opening and closing device (5), the pressure reducing valve (14), the air valve (15), the alarm (2), the accelerator control system (17), the main thrust engine (11), the left thrust engine (9) and the right thrust engine (12) are controlled through a control chip (19), wherein the working states of the mask opening and closing device (5), the pressure reducing valve (14), the air valve (15) and the alarm (2) depend on output signals of the air detector (1), and the output signals of the air detector (1) depend on the concentration conditions of various gases in the surrounding environment; the working states of the main thrust engine (11), the left thrust engine (9) and the right thrust engine (12) depend on an accelerator control system (17); the working state of the throttle control system (17) depends on the output signals of the position sensor (18) and the oil level sensor (20); the main control system (7) comprises an accelerator control system (17), a control chip (19) and a position sensor (18), and signals are transmitted to the accelerator control system (17) through the control chip (19) so as to keep the power balance of the 3 thrust engines;
step two: the air guide pipe connector (6) of the protective helmet (4) is connected with the oxygen bottle (13) through an air guide pipe (16) with a pressure reducing valve (14) and an air valve (15), when the air detector (1) detects that the concentration of toxic gas exceeds the standard, a control chip (19) receives a signal and starts to work, an alarm (2) starts to send an alarm signal, the pressure reducing valve (14) and the air valve (15) are opened immediately, meanwhile, a mask opening and closing device (5) controls a mask (3) to be closed, and the oxygen bottle (13) starts to convey oxygen to the interior of the protective helmet (4); in addition, the accelerator control system (17) starts the main thrust engine (11), the left thrust engine (9) and the right thrust engine (12), the personnel can fly upwards by utilizing the air boosting principle, and meanwhile, the thrust of the left thrust engine and the thrust of the right thrust engine are adjusted by the position sensor (18), so that the personnel are always positioned in the middle position of any cross section of the closed space.
