Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] In Figure 1, 1 is the oxygen hose, which is convenient for users to use when inhaling oxygen; 2 is the upper cover of the life-saving oxygen supply device, which is tightly combined with the box in a sealed manner, which can effectively prevent the evaporation of water; 3 is the conduit , there are power supply wires and wire conduits in between, which can effectively protect the power line; 4 is the hard oxygen pipe in the device, 5 is the water storage tank, and its bottom plate is movable. Once it is installed in the tank, the water storage tank body can be It is divided into electrolytic tank and water storage tank; the water storage tank is used to store the water for electrolysis, and a small amount of low-concentration electrolyte, such as NaOH or KOH, can be added during the period to increase its conductivity; 6 is the central circular shape of the cover...

Abstract

The lifesaving oxygen replenisher for emergency use of persons in condition of mine collapse includes one DC power source of accumulator; one electrolytic bath with anode and cathode connected electrically to the positive and negative poles of the DC power source, stopper carrying pull rod, oxygen output pipe, hydrogen output pipe and porous diaphragm; one water tank for supplying water to the electrolytic bath; and gas output pipelines. The lifesaving oxygen replenisher has simple structure, may be in different sizes and suitable for industrial production. It is used mainly for self-help of miners in emergency, and may be also used in hospital, household and anoxic environment to improve air quality.

Description

technical field [0001] The present invention relates to an automatic oxygen replenishing device used in anoxic environment, and in particular relates to an automatic oxygen replenishing device that can be used by trapped personnel when an obstructive landslide occurs in an underground tunnel of a mine. Background technique [0002] As far as coal mines are concerned, China has the largest coal mining industry in the world, and its annual coal exports account for about 20-30% of world production. However, the annual number of deaths in mining accidents in China accounts for more than 80% of the world's total. According to statistics, for every 100 tons of coal produced in China, 3 miners will die due to mining accidents. This probability is almost 100 times that of the United States. [0003] In addition to factors such as the extensive high-energy-consuming economic development model, one of the main reasons why mining disasters occur frequently is that miners lack sufficie...
