Mining amphibious breathing self-rescuer with protecting cap

Abstract

The invention relates to a mining amphibious breathing self-rescuer with a protecting cap, which comprises a protecting cap 1, a back plate 5, a back strap 6, a high-pressure air bottle 7, a pressure reducer 8, a breathing air box mouthpiece 9, a separate face mask 10, a pressure gauge 11, and the like. A cushion blocking 4 is arranged on the inner side of the protecting cap 1; a neck 2 of a strap 3 is arranged on the protecting cap 1; and the protecting cap 1 can be connected with the high-pressure air bottle 7 or the back plate 5 through the strap 3. The protecting cap can protect the high-pressure air bottle and prevent the high-pressure air bottle on the back from colliding with the top of a laneway or a borehole wall and from being damaged, and further avoid accidents, such as the explosion of the high-pressure air bottle. After water trouble accidents happen to various mines, miners under water can use the mining amphibious breathing self-rescuer with the protecting cap to safely and quickly escape from the water.

Description

technical field [0001] The invention belongs to amphibious respiration self-rescuer for mining, in particular to an amphibious respiration self-rescuer for mine with a protective cover (the protective cover may be referred to as protective cover, the same below). Mine amphibious breathing self-rescuer belongs to a kind of underwater escape equipment used by submerged miners after water disasters in various mines - underwater breathing self-rescuer; at the same time, it can also be used by miners after harmful gases are produced in mines A breathing self-rescuer. The high-pressure gas cylinder protective cover of the mining amphibious breathing self-rescuer with shield can protect the high-pressure gas cylinder from direct collision in the underground roadway, so as to avoid accidents caused by the collision of the high-pressure gas cylinder. Background technique [0002] After the mine flood accident, the submerged miners can rely on the mine amphibious breathing self-rescu...

AI Technical Summary

Problems solved by technology

The mining amphibious breathing self-rescuer uses very mature scuba diving technology, and uses the core equipment of scuba diving equipment to provide underwater escape breathing for miners in distress, but the mining amphibious breathing self-rescuer is used as an escape equipment for miners in water distress There are still deficiencies. When diving in the open waters of rivers, lakes and seas, in addition to using scuba diving equipment, divers also use counterweight lead weights and buoyancy regulators to float and dive independently, so there is no need to consider the collision problem. When a miner carries a mine-used amphibious breathing self-rescuer to escape in a submerged narrow underground tunnel, he only needs to consider floating up and getting out of the water as soon as possible. The gas cylinder will float the human body, and the high-pressure gas cylinder behind the back will inevitably collide with the top of the tunnel or the wall of the well, which will easily cause damage to the high-pressure gas cylinder, and then accidents such as explosion of the high-pressure gas cylinder
