Airplane life-saving device

Abstract

The invention relates to an aircraft lifesaving device which comprises a cold protective jacket and a helium bag connected to the cold protective jacket, and a control part is connected to the cold protective jacket and used for controlling opening of the helium bag. According to the technical scheme, the cold protective clothing has the advantages that necessary warm keeping measures are provided, and people are prevented from losing viability due to the fact that the body temperature is too low in the cold high altitude. The cotton wadded jacket is made of high-tech heat preservation materials and has the advantages of being light, efficient and heat-preservation. In emergency, the helium bag provides buoyancy for the life-saving device to help people to slowly fall down, and hurt caused by high-altitude falling is avoided. When the helium bag is activated, helium inside the helium bag expands rapidly to form a large air bag, and enough buoyancy is provided for a person wearing the cold protective clothing. The control piece is used for controlling opening of the helium bag. Therefore, the problem that civil aircrafts in the prior art generally cannot be equipped with lifesaving equipment such as parachutes is solved.

[0033] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0034] Embodiment 1:

[0035] like Figures 1 to 3As shown, an aircraft lifesaver includes a cold-proof suit 1 and a helium bag 2 connected to the cold-proof suit 1. The cold-proof suit 1 provides warmth for the wearer to cope with the low temperature environment at high altitudes. The helium bag 2 serves as the main buoyancy providing device to help the wearer maintain buoyancy at high altitudes. The control member 4 is used to control the opening of the helium bag. When the user is in a falling state, the control member 4 activates the internal helium to expand rapidly to form a large air bag, providing sufficient buoyancy for the person wearing the cold-proof suit. At the same time, the helium bag 2 is connected to a helium tank 3. The helium tank 3 is liquid helium. Since the boiling point of liquid helium is minus 268°, liquid helium can be quickly converted into helium when it enters the helium bag, thereby realizing rapid inflation of the helium bag. After the helium bag is opened, it becomes a large balloon. The descent speed suddenly decreases.

[0036] The control unit 4 includes an automatic switch 41, a timer 42 and a nine-axis gyroscope 43 connected to the helium bag 2. When the nine-axis gyroscope 43 detects that it is in a falling and rotating state, the timer 42 starts timing. When the timer 42 runs to a specified time, the automatic switch 41 is turned on to control the helium bag 2 to open.

[0037] The helium bag 2 is connected with a satellite positioning device 5 and a compass 51. When an emergency occurs in the aircraft, the user puts on cold-proof clothing and activates the life preserver, and the satellite positioning device 5 and the compass 51 start working at the same time. The satellite positioning device 5 quickly determines the user's precise geographic location and sends the location information to the rescue team through a built-in communication module (such as radio or satellite communication). The compass 51 provides direction indication to help the user determine his or her direction, so that the user can provide additional direction information to the rescue team or find a safe place by himself or herself when necessary.

[0038] The cold-proof clothing 1 is connected with a safety belt 6, which includes a shoulder strap, a waist belt and a leg belt. The main function is to fix the human body and prevent it from moving around in the cold-proof clothing. The cold-proof clothing 1 is connected with an oxygen absorption component 7, which includes an oxygen cylinder and an oxygen absorber.

[0039] Since the air is thin at 10,000 meters, the oxygen content in the air is only 23.6% of that at sea level, so an oxygen absorber needs to be installed at the head position of the cold-proof clothing. Since it only takes 180 seconds to get from 10,000 meters to the ground (excluding the time after the helium bag is opened, when oxygen is no longer needed), and below 3,000 meters, oxygen is no longer needed, so the amount of oxygen required for 180 seconds. Since civil airliners fly mostly at around 10,000 meters, and the highest is 12,000 meters. But the altitudes at which the planes crashed were different.

[0040] The timer in the helium bag is set to the landing time at 10,000 meters, 6 kilometers, and 3 kilometers respectively (the helium bag is opened when it is about 500 meters from the ground). Because of the low altitude of 3 kilometers and below, there is no need for cold-proof clothing and oxygen, and people do not need to enter the sleeping bag. A safety belt can be set on the helium bag 2. At the same time, an alarm 8 is connected to the cold-proof clothing 1 and the helium bag 2. The alarm 8 will be in an alarm state after the user lands, so that he can be searched in time.

[0041] Embodiment 2:

[0042] On the basis of the first embodiment, the present embodiment adds a manual switch 44 to the cold-proof clothing 1, and the manual switch 44 is used to manually open the helium bag 2. When an emergency occurs in the aircraft, such as a crash or an uncontrolled rotation, the nine-axis gyroscope 43 quickly detects these conditions. The timer 42 starts timing and waits for a specified time period to confirm the continuity and necessity of the emergency. When the timing reaches the preset time, the automatic switch 41 is triggered, and the helium bag 2 expands rapidly to provide buoyancy for the user. The user slowly descends to the ground with the buoyancy of the life preserver to avoid injuries caused by falling from a high altitude. However, when the automatic switch 41 is not turned on, the user can manually open the helium bag 2. At the same time, the helium bag 2 is provided with a variety of weight user requirements, such as users with a weight of 50 to 60 kg, users with a weight of 60 to 80 kg, and users with a weight of 80 to 100 kg.

[0043] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0044] Cold-proof clothing provides necessary warming measures to prevent people from losing their ability to survive due to hypothermia in the cold high altitude. Cold-proof clothing uses high-tech insulation materials and is lightweight and highly effective in heat preservation. In an emergency, the helium bag provides buoyancy for the life preserver to help people land slowly and avoid injuries caused by falling from a high altitude. When the helium bag is activated, the helium inside expands rapidly to form a large airbag, providing sufficient buoyancy for people wearing cold-proof clothing. The control part is used to control the opening of the helium bag. This solves the problem that civil aircraft in the prior art are generally unable to be equipped with life-saving equipment such as parachutes.
