Description

TECHNICAL FIELD

[0001] The utility model relates to mine safety protection technical field, concretely is downhole pressure supply water self-rescue device. BACKGROUND

[0002] According to statistical data, the high incidence of mine accidents is closely related to the lack of rescue facilities and the long rescue response time. Therefore, in order to effectively reduce the harm caused by accidents and improve the safety protection level of mine operating personnel, a series of perfect self-rescue facilities must be built in the mine. These facilities should be able to provide necessary life support for operating personnel in various emergency situations.

[0003] The patent with publication number CN220226969U discloses a mine air pressure water supply self-rescue device, which includes a box body, a main gas supply pipeline and a main water supply pipeline connected inside the box body, a plurality of branch gas valves connected to the main gas supply pipeline, a breathing mask connected to each branch gas valve through a breathing hose, a plurality of branch water valves connected to the main water supply pipeline, a suction nozzle connected to each branch water valve through a water suction hose, an openable box cover connected to the box body, and a positioning assembly connected to the inner side of the box cover for positioning the breathing mask and the suction nozzle. The mine air pressure water supply self-rescue device can position the breathing mask and the suction nozzle, on the one hand, preventing the breathing mask from slipping and falling when the box cover is opened, and on the other hand, making the positions of the breathing mask and the suction nozzle more regular, which is convenient for disaster avoidance personnel to obtain and use in time.

[0004] The above-mentioned prior art can position the breathing mask and the suction nozzle, which is convenient for disaster avoidance personnel to obtain and use in time in emergency situations, but it has some limitations. First, when there is no mine disaster, the water in the main water supply pipeline stays for a long time, which can cause water quality deterioration, affecting the health and safety of the user. Second, when a mine disaster occurs, if the main water supply pipeline is broken due to external force or other reasons, the water suction hose inside the box body will not be able to output water, thus failing to meet the emergency water supply needs of personnel. This means that the existing device cannot completely cover all possible emergency situations in actual application, which has certain safety hazards. Therefore, in view of the above problems, we propose a downhole air pressure water supply self-rescue device to realize more comprehensive and efficient self-rescue functions and effectively improve the safety protection of mine operating personnel in disaster situations.
