Problems solved by technology

However, the response time of these "mini" products is as long as 1 to 2 minutes, and the sensitivity level is poor.
[0008] 2. Imported products with high sensitivity are expensive to more than 1,000 yuan. It is obviously meaningless to promote such products as accessories for individual equipment

Abstract

The invention relates to a safety helmet type individual escaping device for gas explosion under a coalmine. The safety helmet type individual escaping device comprises an automatic oxygen respirator, a safety helmet and a control part. A shell of the automatic oxygen respirator is internally provided with an oxygen cylinder, a filter, a pressure reducing valve, a one-way valve, a CO2 absorbent and the like; an electromagnetic valve is connected with a leather bag; a gas duct is connected with the one-way valve which is connected a central blank pipe in the CO2 absorbent; the leather bag is folded in a upper cover; and the bottom of the shell is enclosed. The safety helmet comprises a helmet body, a helmet lining, a breather pipe, a breather hose and the like; the breather pipe is connected with an output pipe of the electromagnetic valve on the oxygen cylinder; and the breather hose is connected with a face contacting mask. In the invention, an early warning signal sent by an early warning network is received through a super-regenerative type receiver module, and is decoded and amplified to an on-off controller to control the opening of the electromagnetic valve which opens the oxygen cylinder and is connected with the face contacting mask through the breather pipe for supplying oxygen; meanwhile a buzzer HA gives out an alarming sound; and a user manually pulls down the face contacting mask to mouth and nose positions. The invention gains precious time for escaping.

Description

technical field [0001] The invention relates to a safety helmet type individual escape device for gas explosion in a coal mine. Background technique [0002] Due to the rapid economic development, the demand for energy is also increasing rapidly. As a country that uses coal as the main raw material, the amount of coal mining is also increasing, so coal mine safety accidents also occur frequently and cause a large number of casualties. After analyzing a large amount of data on mine disaster sites and casualties, it was found that more than 90% of the deaths in underground work were caused by the inhalation of carbon monoxide gas after the gas explosion. [0003] There are life-saving cabins under some large mines. As long as the underground personnel can enter the life-saving cabin smoothly before and after the gas explosion accident, there will be no danger to their lives. There is no way for the device to save itself in a short time. [0004] For a long time, the isolatio...
