An integrated self-rescue device for mine compressed air and water supply

Abstract

The invention discloses a forced air and water supply integrated self-rescuing device for a mine, which comprises a box body (1), wherein an air supply pipe (5) and a water supply pipe (7) are arranged in the box body (1) and converged into an air-water combiner (10), an automatic extrusion valve (2) is arranged on the water supply pipe (7), a breathing mask (11) is provided with an air outlet and a water outlet and connected with the air-water combiner (10) through an air-water connecting hose, and a water supply hose is internally sleeved in the air supply hose to form an air-water connecting hose. The invention has the advantages of simple structure, convenience for operation, reliability and durability and is widely applicable to mine operation.

Description

technical field [0001] The invention belongs to the field of safety lifesaving equipment manufacturing, and in particular relates to an integrated self-rescue device for mine compressed air and water supply. Background technique [0002] At present, in the process of mine development, underground accidents occur from time to time, and casualties are not uncommon. According to the investigation and statistics of relevant departments, in most cases, the casualties are not the immediate death at the time of the accident, but after the accident, the injured cannot get timely rescue resulted in death. [0003] The mine operation environment is complex, the conditions are harsh, and the disasters are serious. In order to ensure the safety of the operators, it is necessary to build and improve the "six major systems" of safety and risk avoidance-monitoring and monitoring system, personnel positioning system, emergency risk avoidance system, compressed air self-rescue system, water ...

AI Technical Summary

Problems solved by technology

[0008]The pocket-type compressed air self-rescue device integrates the air supply control device and the breathing mask into one box, which overcomes a series of shortcomings of the pocket-type compressed air self-rescue device: ① Loud noise; ② It affects the sight of disaster evacuation personnel, and the surrounding is dark, which increases the psychological pressure of disaster evacuation personnel; ③ The pocket material is easily damaged and difficult to maintain; ④ The installation is complicated and inconvenient to operate and use; ⑤ It can only supply wind, but cannot supply water at the same time

[0009] Disadvantages of the existing mask-type compressed air self-rescue device: ①It can only supply air, but cannot supply water at the same time; Manually open the gas supply valve, which slows down the self-rescue speed of disaster evacuation personnel; ③There is no panel partition in the box, the layout is messy, and the operation is inconvenient; ④The connection of the gas supply pipeline is welded, and the manufacturing process is complicated

[0010] At present, the compressed air self-rescue system and the water supply rescue system are still two independent systems, which have not been organically combined. The existing compressed air self-rescue device is only a simple supply of air, which cannot enable disaster avoiders to obtain drinking water while exhaling air. Extend disaster avoidance time
