Description

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

technical field

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

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.

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 supply Rescue system and communication system.

Existing compressed air self-rescue device is generally pocket type and mask type.

Pocket-type compressed air self-rescue device scheme: install a tee on the compressed air self-rescue pipeline, connect the branch pipe, set 5 to 8 valves on the branch pipe, and connect the pressure reducing valve and plastic bag below the valve. When a dangerous situation occurs, disaster avoiders open the valve, put their heads into their pockets, and breathe compressed air.

Mask-type compressed air self-rescue device scheme: integrate the air supply control device into a box, the air supply pipe in the box is connected with the mine compressed air self-rescue system, and install valves, pressure regulating valves, and pressure gauges on the air supply pipe in the box and breathing mask. When a dangerous situation occurs, disaster avoiders pull open the door of the box, open the air supply valve, put on a breathing mask, and breathe compressed air.

Mine compressed air self-rescue devices are currently divided into pocket-type and mask-type compressed-air self-rescue devices. In recent years, mask-type compressed-air self-rescue devices have shown a tendency to replace pocket-type compressed-air self-rescue devices.

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; , Increase the psychological pressure of disaster avoidance personnel; ③The pocket material is easily damaged and difficult to maintain; ④Complicated installation, inconvenient to operate and use; ⑤It can only supply wind, but cannot supply water at the same time.

Disadvantages of the existing mask-type compressed air self-rescue device: ①It can only supply air, but cannot supply water at the same time; ②After opening the door of the box, it cannot automatically supply air, and the air supply valve needs to be opened manually, which slows down the self-rescue speed of disaster avoiders; ③ There is no panel partition in the box, the layout is messy, and the operation is inconvenient; ④ The connection of the gas supply pipeline is welded, and the manufacturing process is complicated.

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.
