Abstract

The invention relates to the technical field of self-rescue devices for mines, in particular to a self-rescue device for mine-used pressurized air water supply, which includes a protective shell, an air pipeline and a water supply tank are fixed on the inner wall of the protective shell, and a plurality of air intake valves are installed at the lower end of the air pipeline. The lower end of each intake valve is connected to a pressure control valve through a connecting pipe, one side of the pressure control valve is connected to a spiral air pipe, the lower end of the spiral air pipe is connected to a breathing mask, and a filter element is placed in the water supply tank, and the top and bottom surfaces of the filter element are There are fixed pieces on both sides, and four sets of U-shaped fixing seats are fixed on the inner wall of the water supply tank. The fixed pieces are inserted into the corresponding U-shaped fixing seats, and the fixed pieces and the U-shaped fixing seats are fixed through the pin shafts. , the upper end of the filter element is provided with a water inlet, and one side of the lower end is provided with a water outlet, the water outlet is connected with a hose, and the upper end of the hose is movably connected to the side wall of the water supply tank. The invention solves the problem that the filter element of the water supply mechanism of the existing self-rescue device is not easy to replace.

Description

technical field

[0001] The invention relates to the technical field of mine self-rescue devices, in particular to a mine-used compressed air water supply self-rescue device. Background technique

[0002] At present, when accidents or harmful gases occur in underground mines in my country, pocket-type compressed air self-rescue devices are mainly used. Conventional self-rescue devices can only guarantee oxygen inhalation requirements, and cannot meet personnel's water supply requirements. Even self-rescue devices with simple water supply mechanisms, There is also no comprehensive filter system, and the filter core is directly fixedly installed in the water supply mechanism, so that the filter core is not easy to replace, which will inevitably affect the normal use of the whole self-rescue device during long-term use. Contents of the invention

[0003] The purpose of the present invention is to solve the shortcomings of simple water supply mechanism and difficult replacement ...
