The water spraying mechanism 500 is further provided with a temperature detection unit for detecting the ambient temperature around the nacelle 210. When the temperature detecting unit detects that the ambient temperature around the cabin 210 reaches a set temperature range, the electromagnetic valve in the water pipe spraying mechanism is automatically opened, and the spraying part 540 sprays water to the cabin 210 and the periphery of the cabin 210, so that the effects of fire prevention, fire extinguishment and temperature reduction to a certain degree are achieved.

In this embodiment, the quick danger avoiding apparatus further includes an alarm 600 provided in the storage box 100. The alarm 600 is mainly composed of a battery compartment, a battery, a control circuit, an LED lamp, a buzzer, a switch, and the like. The alarm 600 is of a compact design and is mounted on the body of the storage box 100 such that the alarm 600 operates when the lid 120 is opened. The flash lamp and the buzzer on the alarm 600 give out sound and light alarm at the same time, so that the rescue personnel can find rescue.

The fire smoke rapid danger avoiding device disclosed by the invention fully utilizes the space structure of the box body in design, is as universal as possible in component model selection, adopts industry standard components, and reduces non-standard components to the maximum extent, so that the purposes of ensuring the safe operation of the danger avoiding device and reducing the manufacturing cost of the danger avoiding device are achieved.

The working principle of the quick fire smoke danger avoiding device is as follows:

when fire smoke occurs, because the corridor is blocked by smoke and fire, people cannot escape from the residence and return immediately, and the residence door and window are closed to seal the residence as much as possible so as to prevent smoke from entering. However, once a fire occurs, adjacent doors and windows around the fire source are damaged, and smoke can enter the residence. To prevent the smoke from suffocating people, the quick danger prevention apparatus should be immediately lifted to a relatively suitable space, the storage box 100 is opened, one end of the main water pipe 510 is immediately pulled out to be inserted into a faucet (the same principle as the water pipe connection of the washing machine) as the conditions permit, and the faucet is turned on. When the cover 120 of the storage box 100 is opened, the switch installed between the main body 110 and the cover 120 is automatically turned on, the flash lamp and the buzzer flash and sound alarm to facilitate the rescue workers to search for rescue, and the water spraying mechanism 500 is turned on. After the box cover 120 is opened, the soft sealed cabin 200 is taken out from the main box body 110, the high-pressure gas cylinder is connected with the inflatable framework 220 on the soft sealed cabin 200 through the gas supply pipe, the high-pressure gas cylinder is opened, and compressed gas in the high-pressure gas cylinder is rapidly filled into the inflatable framework 220 on the cabin body 210 to rapidly support the cabin body 210. According to the number of people entering the cabin, an oxygen candle starting switch (one oxygen candle for each person and one switch for each oxygen candle) is pressed, the oxygen candles are started according to the number of people so as to control the oxygen supply ratio and accurately control the oxygen concentration in the cabin), the oxygen candles are started, and oxygen enters the cabin through an oxygen supply pipe. Then the person pulls open the watertight zipper 213 of the hatch door 211, enters the cabin, pulls on the watertight zipper 213, and the cabin forms a closed space. When the soft sealed cabin 200 is quickly supported, the gas concentration detection unit 710 and the illumination component 720 mounted on the cabin 210 are switched on automatically under the action of the tension of the cabin 210, and the gas concentration detection unit 710 and the illumination component 720 start to work to measure the oxygen and carbon dioxide concentrations in the cabin. Similarly, under the action of the tension of the chamber 210, the protective sealing film on the curtain is pulled away, and the agent on the curtain starts to work to continuously absorb the carbon dioxide in the chamber, so that the concentration of the carbon dioxide in the chamber is kept below the allowable value. The outside conditions can be observed at any time through the observation window 212 during the stay of the person in the cabin. If the air pressure in the cabin is higher than the set value, the one-way exhaust valve 730 on the cabin is opened to exhaust the air outwards to exhaust the redundant air in the cabin. When the temperature detecting unit in the water spraying mechanism 500 detects that the ambient temperature around the cabin 210 reaches a set temperature range (e.g. higher than 39 ℃), the electromagnetic valve in the water pipe spraying mechanism is automatically opened, and the spraying component 540 sprays water onto the cabin 210 and around the cabin 210, thereby playing roles of fire prevention, fire extinguishing and temperature reduction to a certain extent. The personnel can stay in the cabin for a long time and wait for the escape of the external aid or the escape of the smoke and fire after the smoke and fire are dissipated.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
