[0005] Furthermore, the water supply rescue device includes a water supply main pipe, which is connected to the water source in the well. After entering from the top of the box, the water supply main pipe is connected in sequence to the inlet of the pressure reducing valve and the filter. The outlet of the filter is connected to the water supply main pipe. Multiple water circuit ball valves are connected in series on the water supply main pipe. Each water circuit ball valve is connected to a water supply branch pipe to form a water supply self-rescue unit.

[0006] Furthermore, the compressed air self-rescue device includes a main air pipe, which is connected to the downhole air source. After entering from the top of the box, the main air pipe is connected in series with multiple air path ball valves. Each air path ball valve is connected to an air flow regulating valve and a mask in sequence through an air pipe to form a compressed air self-rescue unit.

[0007] Furthermore, a pressure gauge is installed at the end of the water pipe.

[0008] Furthermore, a water collection trough is formed inside the tank below the opening, and the outlet of the water collection trough is located on the bottom surface of the tank, with a drain valve installed on the outlet.

[0009] Furthermore, a door is hinged to the bottom edge of the opening of the box, a retaining edge for limiting the door is provided inside the opening of the box, a pin hole is provided at the top of the opening of the box, and a spring pin is installed at the corresponding position of the door.

[0010] Furthermore, the water branch pipe is a spring hose.

[0011] Furthermore, the air tube between the airflow valve and the mask is a spring-loaded hose.

[0012] Furthermore, ear plates are installed on the top of the enclosure.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This utility model provides a combined water supply rescue and compressed air self-rescue device, which integrates the originally separate water supply rescue device and compressed air self-rescue device into a single housing. This completely solves the problems of traditional split devices, such as scattered installation, inconvenient operation, and the need for personnel to switch positions back and forth. The interfaces of the two self-rescue units (water supply branch pipe and compressed air mask) are distributed side by side within the opening of the housing. Users can quickly and conveniently use the water supply and compressed air self-rescue functions simultaneously or alternately from the same position and facing the same operating surface, greatly improving the efficiency of coordinated operation in emergency situations. A single housing replaces two separate housings, reducing the space occupied by the equipment and making it easier to arrange and install in limited underground spaces.

[0015] The water supply rescue system, through its "main pipe, pressure reduction, filtration, main pipe, and branch pipe" design, ensures the provision of drinking water with stable pressure and clean water quality to meet the basic drinking water needs of trapped personnel. The compressed air self-rescue system, through its "main pipe, branch pipe, regulation, and mask" design, provides adjustable flow and clean, fresh air to meet the breathing needs of trapped personnel and prevent toxic or harmful gases or oxygen deficiency from causing suffocation.

The water supply rescue device and the compressed air self-rescue device are arranged inside the box 1. The water supply self-rescue unit of the water supply rescue device and the compressed air self-rescue unit of the compressed air self-rescue device are arranged in a row within the opening area of ​​the box 1.

[0021] The water supply rescue device includes a main water supply pipe 2, which connects to a well water source. The main water supply pipe 2 enters from the top of the housing 1 and connects sequentially to the inlet of a pressure reducing valve 3 and a filter 4. The outlet of the filter 4 connects to a main water supply pipe 5. Multiple water circuit ball valves 6 are connected in series on the main water supply pipe 5, and each water circuit ball valve 6 connects to a water supply branch pipe 7, forming a water supply self-rescue unit. The pressure reducing valve 3 ensures safe and controllable water pressure, preventing high-pressure water injury; the filter 4 ensures safe water quality, preventing impurities from clogging the water or causing health problems.

[0022] The compressed air self-rescue device includes a main air pipe 8, which is connected to the downhole air source. After entering from the top of the box 1, the main air pipe 8 is connected in series with multiple air path ball valves 9. Each air path ball valve 9 is connected to a regulating airflow valve 10 and a mask 11 in sequence through an air pipe to form a compressed air self-rescue unit.
