Downhole rescue system

Abstract

The invention discloses a downhole rescue system which is connected with a monitoring center. The downhoel rescue system comprises a breathing mask, an air source conversion system, a first air supply system and a second air supply system, wherein the air source conversion system can be switched in the first air supply system or the second air supply system to supply air to the breathing mask. The downhole rescue system enables a user to automatically switch to a standby air source under the emergency that a motor air supply system breaks down, precious time is prolonged, secondary disasters are prevented from occurring in the rescue process to cause unnecessary property loss and casualties, and therefore downhoel rescue operation can be carried out timely, effectively and interactively.

Description

technical field [0001] The invention relates to a rescue system, in particular to a rescue system with a respirator. Background technique [0002] At present, with the increasingly tense global energy demand, the mining industry has developed rapidly. With the continuous increase of underground mining capacity and mining volume, sudden underground water seepage accidents caused by complex underground geological structure and many uncertain factors occur from time to time, causing a large number of casualties and huge property losses. For the industry, mining accidents have always been a lingering shadow. There have been many large coal mine disasters in our country this year, causing huge loss of life and property. At the same time, mine rescue has become the focus of public attention when encountering mine disasters. Compared with foreign countries, although China's mine emergency rescue technology and equipment research and the construction of new mine safety protection ...

Problems solved by technology

Although the life-saving devices used in the market have certain functions such as gas supply, lighting and communication, the functions of these life-saving devices are too single, and often cannot cope with the complex and changeable situations when mine disasters occur, resulting in the ground staff being unable to respond to changes. The rescue work cannot be carried out smoothly due to the correct rescue instructions given under the circumstances, or the trapped people do not have enough oxygen to survive when the conventional oxygen supply is difficult due to the lack of a backup air supply and oxygen supply system. These are not conducive to the trapped people Escape and rescue in time

[0003] In addition, there are many underground operation points and a wide range of operations, involving a variety of situations, and the risk factors and safety hazards are also complicated. A series of problems are often encountered, such as: the type of underground dangerous gas is not clear, and the working hours are restricted. The limitation of the amount of gas to be carried, the lack of lighting facilities at the rescue site, the inability of the monitoring personnel on the well to observe the situation on the site, and the inability of the underground staff to communicate with the monitoring personnel from time to time, etc., have brought certain obstacles to the underground work, and also caused difficulties for the underground staff. Safety of life brings safety hazards
