Abstract

The invention relates to a durable mining lifesaving cabin automatic oxygen supplying system capable of supplying oxygen through a safety oxygen source, and the automatic oxygen supplying system is used for emergency active rescuing for a mine. The durable mining lifesaving cabin automatic oxygen supplying system is composed of an oxygen monitoring device, an oxygen supplying control device and a storage oxygen supplying group. The storage oxygen supplying group is composed of a NO.1 chlorate oxygen candle, a NO.2 chlorate oxygen candle and a NO.N chlorate oxygen candle. The oxygen supplying control device is provided with a programmable logic controller (PLC) control unit, a display controller and an isolation relay unit. The isolation relay unit is provided with a NO.1 relay, a NO.2 relay and a NO.N relay. The oxygen monitoring device is provided with an oxygen sensor. The oxygen content in a lifesaving cabin environment is monitored through the oxygen sensor, then a signal is input to the PLC control unit of the oxygen supplying control device, the relays are sequentially controlled and triggered, the oxygen candles are sequentially lighted, oxygen is generated timely and conveyed continuously, a lifesaving process is continued, and survival of people is guaranteed. The durable mining lifesaving cabin automatic oxygen supplying system has the advantage of being compact in structure, effective to control, durable in storage and safe to use.

Description

Technical field [0001] The invention relates to a storage-resistant oxygen supply equipment for a mine emergency rescue chamber, in particular to an automatic oxygen supply system for a mine rescue chamber with a durable safe oxygen source for oxygen supply. Background technique [0002] When a mine disaster occurs, mine rescue is often a passive behavior, which consumes manpower, material and financial resources, and the results are unpredictable. The mine rescue cabin installed in the mine has become an important equipment for people to actively rescue. The key technology of the mine rescue cabin is the durability, safety and reliability of the oxygen supply system. In the prior art, most of the mine rescue cabins use peroxide medicine boards for oxygen supply, or superoxide medicine boards for oxygen supply, or Oxygen cylinders supply oxygen. The oxygen supply method of the peroxide medicine board uses the peroxide air regeneration medicine board, or the superoxide medic...
