Problems solved by technology

However, when fires, gas and coal dust explosion accidents occur underground in coal mines, a large amount of harmful gases will be produced. Most of the miners who died were stunned by the explosion waves and could not use the compressed oxygen device for self-rescue, resulting in poisoning of harmful gases or hypoxia. Indirect casualties such as suffocation
The current alarm system can only alarm automatically, but cannot combine the compressed oxygen device with the intelligent alarm system. Therefore, a low-power, multi-functional, safe and reliable compressor can be developed that can automatically open the compressor when disasters such as gas occur. The new self-rescue device of the oxygen device is an urgently needed task and subject, and it is of great practical significance to protect the life safety of miners and the safe production of mines

Embodiment 1

[0030] Example 1. Underground gas safety self-rescue device for miners

[0031] This underground gas safety self-rescue device for miners of this example is a self-rescue safety device for miners in underground gas disasters. The self-rescue safety device also includes: an intelligent disaster alarm miner's lamp, an automatic oxygen supply device and an automatic protective mask. The specific structure of the miner's underground gas safety self-rescue device is given by Figure 1 to Figure 16 Jointly shown. figure 1 Shown is the structural block diagram of miners' underground gas safety self-rescue device. figure 1 Middle: 1 is the pressure sensor, 2 is the gas sensor, 3 is the amplification filter, 4 is the single chip microcomputer, 5 is the mining power supply, 6 is the voltage stabilizing circuit, 7 is the automatic oxygen supply device, 8 is the flashing alarm miner's light, 9 is Automated protective mask. figure 2 It is the physical structure diagram of miners' ...

Embodiment 2

[0032] Embodiment 2. Underground gas safety self-rescue device for miners

[0033] The specific structure of the underground gas safety self-rescue device for miners in this example can be Figure 1 ~ Figure 3 etc. jointly show that the underground gas safety self-rescue device for miners in this example differs from the underground gas safety self-rescue device for miners in Embodiment 1: 1. The microcomputer or microprocessor is PLC, model FX3UC. 2. The micromotor of this example adopts the micromotor of known public model. All the rest of the miner's underground gas safety self-rescue device of this example are not described, which are all the same as those described in Embodiment One, and will not be repeated.

Abstract

The invention discloses an underground gas safe self-help device for a miner, and belongs to the technical field of mine disaster monitoring and emergency rescue guarantee. The safe self-help device is an intelligent self-help safety device which is arranged on a safety helmet of the miner and is managed and controlled by a microcomputer or a micro processor and software of the microprocessor. The underground gas safe self-help device further comprises an intelligent alarm miner lamp, an automated oxygen supply device and an automated protective mask. The underground gas safe self-help device is multifunctional, low in power consumption, safe and reliable, a compressed oxygen device can be automatically opened when gas disasters and other disasters happen, and the death rate of workers after mine disasters can be effectively reduced. A common gas alarm system is only provided with a gas sensor, but the underground gas safe self-help device is additionally provided with a pressure sensor, so that the automated oxygen supply device and the automated protective mask can automatically release oxygen when the disaster happen, and people are prevented from breathing harmful gas and dying due to suffocation. The underground gas safe self-help device for the miner is worthy of adoption and popularization.

Description

technical field [0001] The miner's underground gas safety self-rescue device disclosed by the present invention belongs to the technical field of mine disaster monitoring and emergency rescue guarantee, and specifically relates to an intelligent self-rescue safety device equipped with a microcomputer or microprocessor and its software management control on the miner's helmet, which can In the event of gas and other disasters, a microcomputer or microprocessor drives an automatic alarm and an automatic oxygen supply system to carry out miners' safety self-rescue device. Background technique [0002] At present, the known gas warning lamp is to utilize the miner's lamp safety helmet to refit. It can send out a flashing alarm signal when the gas gas in the mine exceeds the limit, reminding miners to pay attention to safety. However, when fires, gas and coal dust explosion accidents occur underground in coal mines, a large amount of harmful gases will be produced. Most of t...
