[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A mine-use compressed air and water supply self-rescue device includes a protective box 1, a door rotatably installed on the protective box 1, and an air supply system 2 and a water supply system 7 installed inside the protective box 1.

[0017] The air supply system 2 includes a main air supply interface 3 and a multi-channel compressed air pipe 5 installed on the protective housing 1. The air inlet of the main air supply interface 3 is connected to the mine compressed air system, and a pressure reducing and stabilizing valve 4 is installed in series between its air outlet and the air inlet of the multi-channel compressed air pipe 5.

[0018] The pressure reducing and stabilizing valve 4 uses existing technology to stabilize the high-pressure gas in the mine compressed air system to a pressure value that is comfortable for human breathing. It also has a pressure overload protection function, which automatically releases pressure when the output pressure exceeds the set value to ensure breathing safety.

[0019] A main air supply valve is installed in series at the connection between the main air supply interface 3 and the protective housing 1. The main air supply valve is a manual shut-off valve, which can control the air circuit opening and closing as a whole, making it convenient to shut off the air circuit when the equipment is under maintenance or idle for a long time.

[0020] Multiple air outlets of the multi-channel compressed air pipe 5 are connected to branch air supply valves 51, and the air outlets of the branch air supply valves 51 are connected to breathing masks 6 through air supply hoses.

[0021] The air supply hose is made of flame-retardant and aging-resistant rubber material, with a certain length reserved to meet the range of movement of personnel in emergencies. The breathing mask 6 is a headband-type half mask with a built-in one-way breathing valve to prevent exhaled gas from flowing back, and the mask edge is equipped with sealing gaskets to improve the sealing performance.

[0022] The water supply system 7 includes a main water supply interface 8 and a multi-channel water supply pipe 10 installed on the protective housing 1. The inlet end of the main water supply interface 8 is connected to the mine pressurized water system, and its outlet end is connected in series with the inlet end of the multi-channel water supply pipe 10 and a filter element assembly 9 is installed.

[0023] A main water supply valve is connected in series at the connection between the main water supply interface 8 and the protective box 1. The main water supply valve is a manual shut-off valve, which can control the water circuit opening and closing as a whole, so as to close the water circuit when cleaning the backup water tank 12 and replacing the filter element assembly 9 to avoid water leakage.

[0024] Multiple outlets of the multi-channel water supply pipe 10 are connected to branch water supply valves 101, and the outlets of the branch water supply valves 101 are connected to water outlet terminals 11 via water supply hoses.

[0025] The main water supply interface 8 and the multi-channel water supply pipe 10 are both made of food-grade stainless steel to avoid secondary water pollution. The pipe connection adopts a compression fitting sealing structure, which is convenient to disassemble and reliably sealed.

[0026] The water supply hose is made of food-grade material, and the water outlet terminal 11 is a push-button type water outlet with anti-drip function. It automatically seals when not in use to avoid water waste.

[0027] The protective housing 1 is equipped with a backup water tank 12, which is connected in series between the main water supply interface 8 and the filter element assembly 9.

[0028] The backup water tank 12 is a one-piece molded structure made of food-grade stainless steel and is used to store emergency water. Its top is equipped with a water inlet that is connected to the main water supply interface 8. When replenishing water, the backup water tank 12 is kept at a full water level.

[0029] A transparent liquid level window 14 is installed on the side of the backup water tank 12 facing the tank door, so that the inspection personnel can observe the water level inside the backup water tank 12 through the transparent liquid level window 14.

[0030] The filter element assembly 9 is detachably installed inside the protective housing 1. The side facing the door has an integrally formed filter element viewing window 16, which allows inspectors to visually observe the contamination status of the internal composite filter element.

[0031] The bottom of the backup water tank 12 is integrally formed with an arc-shaped sludge collection trough 13.

[0032] The arc-shaped sludge collection trough 13 has a structure that is low in the middle and high on both sides, which facilitates the natural settling and collection of impurities such as mud, sand and rust in the water.

[0033] The bottom of the arc-shaped sludge collection tank 13 is connected to a drain valve 15, and the outlet of the drain valve 15 is connected to the mine drainage system.

[0034] The drain valve 15 is a quick-opening ball valve with a threaded interface at its outlet. It can be selectively connected to the mine drainage system. When not connected, it is sealed with a plug cap. When draining, the plug cap can be opened to quickly discharge the sediment in the tank without disassembling the box for cleaning.

[0035] The transparent liquid level window 14 is marked with "full water level" and "emergency water level" scale lines.

[0036] The “emergency water level” scale corresponds to 1 / 3 of the volume of the backup water tank 12, ensuring that the emergency water demand can still be met in extreme situations. The scale lines are made of laser etching technology, which is not easy to wear and makes it easy to quickly identify during inspections.

[0037] The door is fitted with two transparent opening and closing windows 17, which correspond to the transparent liquid level window 14 and the filter element viewing window 16.

[0038] Two transparent opening and closing windows 17 are set independently, corresponding to the positions of the transparent liquid level window 14 and the filter element viewing window 16 respectively. When opened, they can fully expose the observation area without obstructing the operating space.

[0039] The filter element assembly 9 includes a fixed base that is fixedly connected inside the protective housing 1. The fixed base is connected in series between the backup water tank 12 and the multi-channel water supply pipe 10. The filter element body is assembled on the fixed base through a detachable structure. After the two are assembled, the filter element body is connected in series between the backup water tank 12 and the multi-channel water supply pipe 10.

[0040] The mounting base is made of stainless steel and is fixed to the inner wall of the protective box 1 with bolts. Its inlet and outlet are connected to the spare water tank 12 and the multi-channel water supply pipe 10 through sealing joints to ensure the water circuit is sealed.

[0041] The detachable structure features a spring-loaded buckle design. The mounting base has spring-loaded buckles on both sides, and the filter element body has corresponding slots on both sides. During assembly, the filter element body is pushed into the mounting base, and the buckles automatically engage with the slots to secure it. At the same time, the sealing ring connectors at both ends of the filter element body fit tightly with the mounting base interface to achieve a sealed connection, allowing water to flow without additional operation. During disassembly, simply pull the spring-loaded buckles to remove the filter element body.

[0042] A rubber sealing gasket is provided between the transparent opening and closing window 17 and the box door, and a positioning buckle is installed on the outside of the transparent opening and closing window 17.

[0043] The positioning buckle is a push-type elastic buckle. When the transparent opening and closing window 17 is slid to the "fully open" or "fully closed" position, the buckle automatically pops out and locks, preventing the transparent opening and closing window 17 from sliding on its own due to transportation or underground vibration, ensuring sealing effect and observation stability. To unlock, simply press the buckle to push the window.

[0044] During gas supply, the gas from the mine compressed air system enters through the main gas supply interface 3, is controlled by the main gas supply valve, and after being stabilized to a comfortable pressure by the pressure reducing and stabilizing valve 4, flows into the multi-channel compressed air pipe 5. Self-rescue personnel can open the corresponding branch gas supply valve 51 as needed and breathe by connecting the breathing mask 6 through the gas supply hose.

[0045] During water supply, the water source of the mine pressurized water system is connected through the main water supply interface 8. The water circuit is controlled by the main water supply valve. The water first flows into the backup water tank 12 for storage. Impurities settle into the arc-shaped sludge collection tank 13, and then enter the top multi-channel water supply pipe 10 after being filtered by the filter element assembly 9. The branch water supply valve 101 is opened, and water is taken for drinking from the water outlet terminal 11 through the water supply hose.

[0046] During the inspection, the inspectors confirmed that they could clearly see the water level scale on the transparent liquid level window 14 through the transparent opening and closing window 17, and confirmed that the water level was within the effective range of "full water level - emergency water level". At the same time, they observed the filter element viewing window 16 to check whether the filter element was clean, undamaged or severely contaminated.

[0047] Visual inspection revealed no signs of aging, damage, or tangling in the gas and water supply hoses. No leaks were found at the main gas supply interface 3, the main water supply interface 8, or any pipe connections.

[0048] Lightly touch the handles of the main air supply valve, the main water supply valve, the branch air supply valve 51, and the branch water supply valve 101 to confirm that the switches are flexible and without jamming, and that the drain valve 15 cap is properly sealed.

[0049] If the water level is lower than the emergency water level, open the main water supply valve to add water to the full level and then close it; if the filter element is contaminated or damaged, or the valve operation is abnormal, pull the corresponding transparent opening and closing window 17, replace the filter element or repair the valve; if the arc-shaped sludge collection tank 13 needs to be cleaned, open the drain valve 15 to drain the sludge, reset the plug, and then add water.

[0050] After the operation is completed, reset the transparent opening and closing window 17 and lock the positioning buckle to ensure the door is sealed, and record the inspection results.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
