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 coal mine underground, which comprises a self-rescuer body, an oxygen storage chamber is opened on the side wall of the self-rescuer body, an air bag is fixedly connected to the upper end of the self-rescuer body, and an air bag communicating with the inside is installed on the upper end of the air bag. The breathing mask, the side wall of the self-rescuer body is provided with a water storage tank, the side wall of the self-rescuer body is provided with a first circular groove, and an air intake pipe is connected between the first circular groove and the oxygen storage chamber, and the first circular groove An air outlet pipe communicates with the air bag, and a control valve is installed in the air outlet. In the present invention, the water flows into the exhaust pipe and is fully combined with the smoke before being discharged, which can greatly reduce the smoke concentration near the escape personnel wearing the self-rescuer, so that the escape personnel can clearly see the nearby road conditions and fire conditions, thereby increasing the survival possibility of the escape personnel. The mist-like water is sprayed on the wearer's body to replace the loss of water inside the human body, which can avoid dehydration and death of escape personnel, thereby improving the self-rescue performance of the device.

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...
