Anti-explosion and heat-insulating structure of mine rescue capsule

Abstract

The invention discloses an anti-explosion and heat-insulating structure of a mine rescue capsule. The anti-explosion and heat-insulating structure of the mine rescue capsule comprises a capsule body and a capsule door, wherein the capsule body comprises a framework, an inner wall and an outer shell body, wherein the inner wall is arranged on the inner surface of the framework, the outer shell body is arranged on the outer surface of the framework, the framework is in a structure of a Chinese character 'mi', an interlayer is formed between the inner wall and the outer shell body, the interlayer is filled with water, and opening holes are formed in the framework to form a water flow passage inside the interlayer. The framework in the structure of the Chinese character 'mi' is capable of greatly improving anti-explosion capacity of the rescue capsule, reducing weight and saving cost. The flow passage formed by a plurality of the holes is arranged on the framework in the structure of the Chinese character 'mi' inside the interlayer, and the water in a water pressing system enters a water inlet, flows through the flow passage on the framework in the structure of the Chinese character 'mi' and fills the whole interlayer. The interlayer can play a role of insulating outside heat to enter the capsule due to high specific heat capacity of the water when a mine disaster occurs and outside temperature is higher than the temperature inside the capsule. The water in the interlayer can serve as the drinking water for people inside the capsule to drink in emergency.

Description

technical field [0001] The invention relates to the field of safety and lifesaving, in particular to a mine lifesaving explosion-proof heat insulation structure. Background technique [0002] The mine rescue cabin is also called "underground refuge". Provide a safe confined space for personnel. According to the surveys of mine accidents in various countries in the world, the miners who were injured and died instantly at the scene of fire, explosion and other accidents only accounted for a part of the casualties in the accident. Fleeing from the scene of high temperature, toxic and harmful gases, resulting in drowning, suffocation or poisoning death. Therefore, all countries are vigorously developing mine rescue cabins to provide a safe confined space for miners who cannot evacuate in time after a mine accident occurs. This confined space completely isolates the internal personnel from the outside environment and provides oxygen and food for trapped miners. And water, to r...

AI Technical Summary

Problems solved by technology

Most of the cabins currently used are supported by a skeleton of steel structure inside or outside the shell. The skeleton is welded by structural steel, and the structural steel is either vertical or parallel. To achieve higher strength, the structure needs more Structural steel, which increases the cost and increases the weight of the cabin, which is not conducive to disassembly and handling

At present, the way to isolate high temperature is to fill the inside of the shell with an appropriate amount of heat insulating material. The heat insulating material occupies a large volume and cannot be used for other purposes, and it is difficult to replace
