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...
