Problems solved by technology

[0003] When a fire breaks out in an underground coal mine, not only a large amount of oxygen is consumed, resulting in a greatly reduced oxygen concentration in the underground, but also a large amount of smoke will be generated, which will block the sight of the escaped personnel and greatly reduce the possibility of survival of the escaped personnel. , In addition, when a fire occurs, it will also generate high temperature, which will easily evaporate the water in the human body, and easily dehydrate the trapped people in the mine to death.
However, the existing compressed oxygen self-rescuer can only provide oxygen for breathing in dangerous moments, and has low self-rescue performance. In view of this, this application document proposes a compressed oxygen self-rescuer for underground coal mines

Embodiment 1

[0020] refer to Figure 1-2 , a compressed oxygen self-rescuer for underground coal mines, comprising a self-rescuer body 1, an oxygen storage chamber 2 is opened on the side wall of the self-rescuer body 1, an airbag 11 is fixedly connected to the upper end of the self-rescuer body 1, and an airbag 11 is installed on the upper end of the airbag 11. The breathing mask 12 that the inside communicates. The airbag 11 is provided with a carbon dioxide absorber for absorbing the carbon dioxide exhaled by people, and the material of the absorber is calcium hydroxide.

[0021] The side wall of the self-rescuer body 1 is provided with a water storage tank 3. It should be noted that the side wall of the self-rescuer body 1 is provided with a water injection port communicating with the water storage tank 3, and water can be added to the water storage tank 3 through the water injection port.

[0022] The side wall of the self-rescuer body 1 is provided with a first circular groove 6, an...

Embodiment 2

[0033] refer to Figure 3-4 , different from Embodiment 1, one of the blades of the exhaust fan 9 is made of iron, and the remaining blades are made of non-magnetic material, and the side wall of the self-rescuer body 1 is provided with a strip groove 14, and the strip groove 14 A bar magnet 15 is slidably connected to the inside, and the bar magnet 15 is elastically connected to the inner wall of the bar slot 14 through a spring 17, and a helical coil 16 is embedded on the inner wall of the bar slot 14. It should be noted that the helical coil 16 is only arranged on a part of the right side of the strip groove 14, and the distance that the bar magnet 15 moves back and forth is greater than the length of the helical coil 16, so that the bar magnet 15 can enter and exit the helical coil 16 to generate an induced current.

[0034] A warning light 13 coupled with a helical coil 16 is installed on the side wall of the self-rescuer body 1 . The installation method between the warn...

Abstract

The invention discloses a compressed oxygen self-rescuer for an underground coal mine. The compressed oxygen self-rescuer comprises a self-rescuer body, wherein an oxygen storage cavity is formed in the side wall of the self-rescuer body; an air bag is fixedly connected to the upper end of the self-rescuer body; a respirator communicating with the interior of the air bag is installed at the upperend of the air bag; a water storage tank is formed in the side wall of the self-rescuer body; a first circular groove is formed in the side wall of the self-rescuer body; an air inlet pipe communicates between the first circular groove and the oxygen storage cavity; an air outlet pipe communicates between the first circular groove and the air bag; and a control valve is installed in an air outlet.According to the compressed oxygen self-rescuer, water flows into an exhaust pipe to be fully combined with smoke and then is discharged, the concentration of smoke nearby an escape person wearing the self-rescuer can be greatly reduced, the escape person can clearly see the nearby road condition and the fire condition, and therefore the survival possibility of the escape person is increased; mist water is sprayed to the body of a wearer to replace water loss in the human body, the escape person can be prevented from being dehydrated and died, and therefore the self-rescue performance of thedevice is improved.

Description

technical field [0001] The invention relates to the technical field of related equipment in underground coal mines, in particular to a compressed oxygen self-rescuer for underground coal mines. Background technique [0002] Compressed oxygen self-rescuer, also known as isolated compressed oxygen self-rescuer, is a reusable self-rescue escape device that uses high-pressure compressed oxygen as the oxygen source. Use in case of sexual disaster. [0003] When a fire breaks out in an underground coal mine, not only a large amount of oxygen is consumed, resulting in a greatly reduced oxygen concentration in the underground, but also a large amount of smoke will be generated, which will block the sight of the escaped personnel and greatly reduce the possibility of survival of the escaped personnel. , In addition, when a fire occurs, it will generate high temperature, which will easily evaporate the water in the human body, and easily dehydrate the trapped people in the mine to de...
