Description

Technical Field

[0001] This invention belongs to the field of coal mine safety technology and relates to a segmented and combined box-type compressed air and water supply self-rescue device and its usage method. Background Technology

[0002] The box-type compressed air and water supply self-rescue device is an open-type emergency supply self-rescue device that provides fresh air and drinking water. The supplied air and drinking water come from the mine compressed air self-rescue system and the mine water supply rescue system, which are part of the six major mine safety and disaster prevention systems. It is one of the simplest and most effective respiratory protection devices for respiratory accidents. After a disaster, when escape routes are blocked (including blocked tunnels and exposure to toxic gases in the respiratory environment), this device can establish a refuge for those in distress, providing necessary survival conditions. It can also provide a relay for breathing and water supply when the escape distance is long. Once the environmental conditions in the disaster area are suitable, the device can be replaced with a mining self-rescue device to continue the escape.

[0003] However, currently, domestically produced box-type compressed air and water supply self-rescue devices are all single-box structures, accommodating 6-8 people simultaneously. All components are integrated within a single box, such as a mine compressed air self-rescue device (CN222102089U), a mine compressed air and water supply self-rescue device (CN207093135U), and a mine compressed air and water supply self-rescue device (CN205779001U). The air supply section includes air supply pipelines, shut-off valves, gas pressure reducing and purification components, hoses, and masks; the water supply section includes pressure reducers, water supply pipelines, purification devices, shut-off valves, and drinking water pipes. Typically, a mechanical latch is fixed to the box door. Pushing the latch manually locks the door; pulling it out separates the door from the box body, and then manually flipping the door open again. Air is diverted from the main air supply pipeline, passing through shut-off valves to the gas pressure reducing and purification device for regulation and filtration, before flowing out through breathing hoses and masks. The shut-off valve is normally closed. When gas is supplied, the shut-off valve handle is manually rotated to open it, and the rotation angle can be adjusted. Water in the main water supply pipeline is reduced in pressure by the water pressure reducer and then filtered by the drinking water purification device. After being diverted, it is transported through pipelines to the shut-off valve, which is connected to the drinking water pipe. The shut-off valve is normally closed. When drinking water, the shut-off valve handle is rotated to open it, and the end of the drinking water pipe is picked up and the water is put into the mouth.

[0004] In conclusion, although the box-type compressed air and water supply self-rescue device has been widely used both domestically and internationally for many years and has played an important role in providing favorable conditions for emergency shelter and escape, it also has the following problems: (1) The opening speed is slow. When the device is activated, the pins fixed to the box must be manually pulled out first, and then the box door must be opened manually, which seriously affects the convenience of opening the box.

[0005] (2) Limited space for centralized use. The 6 to 8 breathing modules are densely arranged in a single box with a length of about 0.8m. After a disaster, it is easy for multiple people to take them together, which will cause crowding and chaos and seriously affect the synchronization of wearing.

[0006] (3) Inability to supply air automatically. Each mask is equipped with a corresponding air supply shut-off valve, which are interconnected in sequence through a spiral hose and a gas pressure reducing and purification device. After manually laying the spiral hose and wearing the mask, the shut-off valve needs to be turned on immediately. However, due to the dim lighting, the tangled spiral hoses, the mask being stuck on the shut-off valve handle, and the anxiety and panic of the people in distress, it is difficult to accurately distinguish and lock their respective breathing components with the naked eye and quickly complete the integrated operation of laying the hose, wearing the mask and opening the valve, which seriously affects the timeliness of air supply.

[0007] (4) Inconvenient flow rate adjustment. The air supply of a single breathing component can only be adjusted by manually changing the output pressure of the gas pressure reducing and purifying device or the opening of the shut-off valve. This requires personnel to be close to the chamber and operate while observing, which leads to the problem of multiple people working together, seriously affecting the timeliness of flow rate adjustment.

[0008] (5) Lack of regular sewage discharge capacity. Sewage, impurities and other harmful substances will continuously accumulate in the compressed air pipeline of the mine. If there is no sewage discharge measures during the inspection or if the sewage is not discharged for a long time, it will easily lead to a large amount of sewage. After direct ventilation, the gas pressure reduction and purification device cannot completely purify it, which will enter the human body and cause harm. At the same time, it is difficult for people to breathe smoothly, which seriously affects respiratory health and comfort.

[0009] (6) Lack of information sensing function. The existing purely mechanical gas and water supply integrated structure cannot monitor and acquire information on the gas supply status at the mask end in real time, and it is not connected to the monitoring platform. The post-disaster usage status of the device is unknown, and the ground command cannot dynamically grasp the location of the personnel in distress underground and the gas supply parameters, which seriously affects the pertinence of the rescue plan. Summary of the Invention

[0010] In view of this, the purpose of this invention is to provide a segmented, box-type compressed air and water supply self-rescue device and its usage method. It adopts an overall structural design in which breathing components are distributed in multiple interconnected boxes, and a centralized water purification source is located in the main box. It integrates mask, air supply, water supply, protection, and monitoring modules. A composite transmission mechanism with one-button pressing and assisted flipping allows for rapid separation and lowering of the box door, laying out a mask with controllable airflow at the end. Air supply is linked to the device based on a pneumatic push-rod valve. It also features daily discharge of impurities and wastewater, as well as intelligent monitoring of air pressure. This addresses the problems of existing box-type compressed air and water supply self-rescue devices, such as congestion, slow opening speed, inability to automatically supply air, inconvenience in mask retrieval and flow adjustment, poor air supply quality, and lack of information collection and feedback mechanisms.

[0011] To achieve the above objectives, the present invention provides the following technical solution: A segmented, box-type compressed air and water supply self-rescue device includes an external compressed air pipe, an external water supply pipe, a main box, and at least one sub-box. The main box includes a box body, a box door, a main box air supply section, a main box water supply section, and a box door quick-opening mechanism. The main box air supply section and the main box water supply section are arranged inside the box body. The main box air supply section includes a top rod valve and a multi-way quick connector connected in sequence to the external compressed air pipe. The multi-way quick connector is connected to at least one gas pressure reducing and purification device, and the gas pressure reducing and purification device is connected to a mask. The main water supply section includes a drinking water purification device and a first water supply tee connector connected in sequence to the external water supply pipe. One outlet of the first water supply tee connector is connected to the drinking water pipe, and the other outlet is connected in series with the second to Nth water supply tee connectors, or connected to a sub-box. When the other outlet of the first water supply tee connector is connected in series with the second to Nth water supply tee connectors, one outlet of each of the second to Nth water supply tee connectors is connected to the drinking water pipe, and the other outlet of the Nth water supply tee connector is connected to a sub-box. The compartment includes a box body, a box door, a compartment air supply section, a compartment water supply section, and a box door quick-opening mechanism. The compartment air supply section and the compartment water supply section are arranged inside the box body. The compartment air supply section includes a top rod valve and a multi-way quick connector connected in sequence to the external compressed air pipe. The multi-way quick connector is connected to at least one gas pressure reducing and purification device, and the gas pressure reducing and purification device is connected to a mask. The sub-tank water supply section includes a first water supply tee connector connected to either the first water supply tee connector or the Nth water supply tee connector in the main tank. One outlet of the first water supply tee connector in the sub-tank is connected to a drinking water pipe, and the other outlet is connected in series with the second water supply tee connector to the Nth water supply tee connector, or connected to another sub-tank. When the other outlet of the first water supply tee connector is connected in series with the second water supply tee connector to the Nth water supply tee connector, one outlet of each of the second water supply tee connector to the Nth water supply tee connector is connected to a drinking water pipe, and the other outlet of the Nth water supply tee connector is connected to another sub-tank. The quick-opening mechanism for the cabinet door includes a switch lock, a spring booster, and a push rod. The cabinet body and the cabinet door are hinged together, and a switch lock is provided between the cabinet body and the cabinet door to close the cabinet door. A spring booster is provided at the hinge of the cabinet body and the cabinet door to assist in opening the cabinet door after the switch lock is opened. The push rod is set on the cabinet door and cooperates with the push rod valve. When the cabinet door is closed, the push rod pushes against the push rod valve, so that the push rod valve is closed. When the cabinet door is opened, the push rod disengages from the push rod valve, so that the push rod valve is opened.

[0012] Furthermore, in the main air supply section, the external compressed air pipe is connected to the top rod valve in sequence via a quick-connect fitting, a first air supply tee fitting, a second air supply tee fitting, a shut-off valve, and a main air supply hose.

[0013] Furthermore, in the sub-box air supply section, the top rod valve is connected to the second air supply tee in the main box air supply section to connect to the external compressed air pipe; and between the second air supply tee in the main box air supply section and the top rod valve in the sub-box air supply section, a compressed air connecting pipe, a quick-connect fitting, a first air supply tee, a second air supply tee, a shut-off valve, and a main air supply hose are sequentially provided.

[0014] Furthermore, a drain valve is connected to the first air supply tee in the sub-box and the main box.

[0015] Furthermore, wind pressure sensors are connected to the multi-port quick-connect fittings in the sub-box and main box, and the wind pressure sensors are electrically connected to the coal mine monitoring substation to transmit electrical signals to the ground command center, indicating that the device has been turned on for maintenance or emergency use.

[0016] Furthermore, a spiral hose and a shut-off valve are sequentially connected between the gas pressure reducing and purification device and the mask.

[0017] Furthermore, a quick-connect fitting, a water pressure reducer, a shut-off valve, and a water pressure gauge are sequentially connected between the external water supply pipe and the drinking water purification device.

[0018] Furthermore, a shut-off valve is installed between each water supply tee and the drinking water pipe.

[0019] Furthermore, the first water supply tee or the Nth water supply tee in the main tank is connected to the first water supply tee in the sub-tank via a water supply connection pipe and a quick-connect fitting.

[0020] Furthermore, the multi-port quick-connector is a five-port quick-connector, connected to three gas pressure reducing and purification devices.

[0021] Furthermore, hooks are arranged on the upper side of the box to facilitate the installation of the box.

[0022] Furthermore, the mask is hung on the box door via a mask hook, and the box door opens downwards, so that the mask can automatically detach under the action of gravity and centrifugal force.

[0023] A method of using the segmented, combined box-type compressed air and water supply self-rescue device includes the following steps: (1) Connect the external compressed air pipe and the external water supply pipe to the air source and water source; (2) Open the box door with a one-button push-button switch lock, the spring booster flips the box door, the top rod valve opens, and air is automatically supplied to the mask, so that the mask can be put on; (3) Drink water through a drinking pipe.

[0024] Furthermore, in the main air supply section, the external compressed air pipe is connected to the top rod valve in sequence through a quick-connect fitting, a first air supply tee fitting, a second air supply tee fitting, a shut-off valve, and a main air supply hose, and a drain pipe valve is connected to the first air supply tee fitting. The drain valve is normally closed, but is opened during routine inspections to discharge impurities.

[0025] Furthermore, wind pressure sensors are connected to the multi-port quick-connect connectors in the sub-box and main box, and the wind pressure sensors are electrically connected to the coal mine monitoring substation to transmit electrical signals; The wind pressure sensor monitors the pressure transmission of the gas supply section, which is then transmitted to the ground command center via the coal mine monitoring substation for location and status assessment.

[0026] Furthermore, a shut-off valve is installed between each water supply tee and the drinking water pipe to regulate the water flow through the shut-off valve.

[0027] Furthermore, in the gas flow process, the gas source is diverted to the gas pressure reducing and purification device via an external compressed air pipe, a top rod valve, and a multi-way quick-connect fitting, and finally flows to the mask, and is connected to the distribution box via a compressed air connecting pipe before the top rod valve.

[0028] Furthermore, in the water flow process, the water source is diverted to the drinking water pipe via an external water supply pipe, a water pressure reducer, a drinking water purification device, and a water supply tee connector, and then to the distribution box via a water supply connection pipe after the drinking water purification device.

[0029] The beneficial effects of this invention are as follows: The segmented, modular, box-type compressed air and water supply self-rescue device provided by this invention significantly improves emergency self-rescue efficiency in confined spaces such as coal mines and tunnels through its series-connected multi-box structure and integrated functional modules. The device employs a layout where the main box centrally purifies the water source, while the sub-boxes disperse the breathing components. It utilizes stainless steel flexible metal hoses and gas-liquid quick-connect couplings to achieve seamless series delivery of gas and drinking water. While the total number of breathing components remains unchanged, the number of individual box components is reduced, effectively alleviating the crowding and confusion problem when multiple people use the device simultaneously, and improving the synchronization of wearing and the timeliness of operation. Simultaneously, the one-button press-type box door separation combined with a spring-assisted flipping mechanism simplifies the opening process to instantaneous completion, greatly shortening the opening time and solving the time-consuming and labor-intensive defects of traditional manual pin operation. Furthermore, based on the linkage design of the pneumatic push-rod valve, it ensures automatic air supply upon opening the box door. With other shut-off valves normally open, only mechanical compression and extension switching are needed to switch the air path on and off, further enhancing the air supply response speed and reliability.

[0030] Regarding mask retrieval and adjustment, this device innovatively hangs the masks on angled hooks on the inner wall of the cabinet door. When the cabinet door is quickly flipped, the masks automatically slide down using gravity and centrifugal force, making it easy for personnel to put them on quickly and avoiding the inconvenience caused by mixing masks inside the cabinet in traditional cabinets. Simultaneously, the mask's air inlet is equipped with a directional adjustable quick-connect shut-off valve, allowing users to manually adjust their breathing flow remotely from dispersed locations, unaffected by dim lighting or harsh environments, solving the problem of difficulty in positioning and adjustment when multiple people are operating the device. Furthermore, each cabinet's air inlet is equipped with a vertical drainage structure, facilitating daily inspections to open and discharge wastewater and impurities, ensuring efficient filtration by the gas pressure reduction and purification device, improving air supply quality, reducing the risk of breathing obstruction, and maintaining the user's health and comfort.

[0031] Finally, the device incorporates a built-in wind pressure sensor, powered by a mine monitoring substation and outputting digital signals. This enables real-time monitoring and transmission of wind pressure to the ground platform after the enclosure door is opened, aiding in determining the device's location and the movement of personnel in distress. This helps in developing targeted rescue plans, overcoming the shortcomings of existing purely mechanical structures that lack information feedback. Overall, this invention improves the device's intelligence, safety, and ease of maintenance while reducing operational complexity and cost. It is suitable for various emergency evacuation scenarios, providing more reliable breathing and drinking water protection.

[0038] Example 1 like Figures 1 to 6 As shown, this embodiment provides a segmented, box-type compressed air and water supply self-rescue device. The device mainly includes a main box 1, a sub-box 2, an external compressed air pipe 3, an external water supply pipe 4, a compressed air connecting pipe 5, and a water supply connecting pipe 6. The main box 1 and sub-box 2 are connected in series via the compressed air connecting pipe 5 and the water supply connecting pipe 6, forming a segmented structure that facilitates dispersed deployment in confined spaces such as coal mines or tunnels, reducing crowding when multiple people use it simultaneously. Specifically, one end of the external compressed air pipe 3 is quickly inserted into an external air source pipe via a quick-connect female connector 49, and the other end is quickly inserted into a quick-connect male connector 40 on the left side of the main box 1 via a quick-connect female connector 49, thus introducing an air source. Similarly, one end of the external water supply pipe 4 is connected to an external water source pipe via a quick-connect female connector 49, and the other end is connected to a quick-connect male connector 40 on the left side of the main box 1 via a quick-connect female connector 49, thus introducing a water source. The male quick-connect connector 40 on the right side of the main box 1 is connected to the male quick-connect connector 40 on the left side of the sub-box 2 via a compressed air connecting pipe 5 (including a vent pipe and female quick-connect connectors 49 at both ends), enabling series gas delivery. Another male quick-connect connector 40 on the right side of the main box 1 is connected to the male quick-connect connector 40 on the left side of the sub-box 2 via a water supply connecting pipe 6 (similar in structure to the compressed air connecting pipe 5), enabling series drinking water delivery. Both the male quick-connect connector 40 and the female quick-connect connector 49 are gas-liquid open-close quick-connect connectors with a self-sealing function, automatically closing when not connected to prevent gas or liquid leakage.

[0039] The main unit 1 includes a unit body 25, a door 45, an air supply unit, a water supply unit, and a quick-opening mechanism for the door (see...). Figure 2 , Figure 3 and Figure 4The specific structure of the gas supply section is as follows: the quick-connect male connector 40 on the left side of the main box 1 is connected to the transition connector 41 by a thread. The right side of the transition connector 41 is connected to the tee connector 42 (i.e., the first gas supply tee connector). The lower port of the tee connector 42 is connected to the drain pipe valve 7 (normally closed, used to manually open during daily inspections to discharge sewage and impurities from the pipe, preventing dirt from entering the human body and affecting respiratory health). The right port is connected to another transition connector 41, and the right side of the transition connector 41 is connected to another tee connector 42 (i.e., the second gas supply tee connector). The three-way connector 42 (i.e., the second gas supply three-way connector) is divided into two paths: one path is sequentially threaded to the transition connector 41, the metal gas pipe 44, the transition connector 41, and the quick-connect male connector 40, forming the main gas path for delivering gas to the distribution box 2; the other path is sequentially threaded to the transition connector 41, the metal gas pipe 44, the third shut-off valve 21 (normally open, used to shut off the gas supply to the main box 1 for easy maintenance), the transition connector 41, the two-way connector 23, and the quick-connect connector 22, forming a branch path, which is then quickly connected to one end of the main gas supply hose 24, and the other end of the main gas supply hose 24 is quickly connected to the top rod valve 12. The other end of the top rod valve 12 is quickly connected to the five-way quick-connect connector 15 (i.e., the multi-way quick-connect connector). The five-way quick-connect connector 15 is divided into two paths: one path is sequentially quickly connected to the vent pipe 17, the second shut-off valve 16 (normally open), the vent pipe 17, and the wind pressure sensor 18, which is fixed on the mounting base 19. The base 19 is installed on the box and is powered by the coal mine monitoring substation 50. It transmits the detected wind pressure digital signal to the coal mine monitoring substation 50 through a serial bus, and then gradually uploads it to the ground monitoring platform for real-time monitoring of the device's usage status and to assist in locating personnel in distress. The other branch of the five-way quick-connect connector 15 is a 3-way branch gas supply pipe 26 (3 in this embodiment, but can be adjusted to other numbers as needed). Each branch gas supply pipe 26 is quickly connected to the elbow quick connector 27 on the gas pressure reducing and purification device 28. The gas pressure reducing and purification device 28 has functions such as manual knob adjustment of output pressure, filtering impurities, purifying gas, and automatic drainage (automatic drainage when the internal water reaches the upper limit). The elbow quick connector 27 at the other end is quickly connected to the spiral hose 29. The other end of the spiral hose 29 is quickly connected to the fourth shut-off valve 30. The fourth shut-off valve 30 is connected to the adapter 31 and the mask 32 through a threaded connection to achieve the final gas output. The fourth shut-off valve 30 is located near the mask 32, which allows the user to manually adjust the air volume after wearing it. The mask 32 is hung on the mask hook 33 inside the door 45 (with an upward angle design for easy automatic sliding down).

[0040] The specific structure of the water supply section is as follows: The quick-connect male connector 40 on the left side of the main tank 1 is threadedly connected to the transition connector 41. The right side of the transition connector 41 is threadedly connected to a tee connector 42. This tee connector 42 is divided into two paths: one path is threadedly connected sequentially to the transition connector 41 and a metal water pipe 43 (a blind pipe design used to cut off water flow and avoid unnecessary branches; that is, the two ends of the metal water pipe are not connected, meaning the incoming water stops after reaching the metal water pipe); the other path is threadedly connected sequentially to a water pressure regulator 20 (which reduces high-pressure water to a safe drinking pressure), a third shut-off valve 21 (normally open, used to close the water inlet to the tank), the transition connector 41, the two-way connector 23, and the tee connector 42. The tee connector 42... One end is threaded to a water pressure gauge 8 (which displays the water pressure after depressurization in real time for easy monitoring), and the other end is threaded to a corrugated water pipe 10 via a nut 11. The other end of the corrugated water pipe 10 is threaded to the inlet of the drinking water purification device 39 via a nut 11. The outlet of the drinking water purification device 39 is threaded to another corrugated water pipe 10 via a nut 11. The other end of the corrugated water pipe 10 is sequentially threaded to a transition joint 41 and a tee joint 42 (here, the first water supply tee joint), a tee joint 42 (here, the second water supply tee joint), a tee joint 42 (here, the third water supply tee joint, i.e., the Nth water supply tee joint), and a quick-connect male connector 40, forming the main water supply line for transporting purified water to the distribution tank 2. Meanwhile, the three T-connectors 42 in the water supply pipeline (three in this embodiment, adjustable) are threaded to the first shut-off valve 13 respectively. Each first shut-off valve 13 is quickly connected to the drinking water pipe 14. When the user drinks water, he / she can manually open the first shut-off valve 13 and put the end of the drinking water pipe 14 into his / her mouth to drink the purified water.

[0041] The specific structure of the quick-opening mechanism for the cabinet door is as follows: a long nut 36 is welded to the inner side of the cabinet door 45; a push rod 38 is screwed into the long nut 36 via an external thread (the exposed length is adjustable); a positioning nut 37 is installed between the push rod 38 and the long nut 36 to fix the position of the push rod 38 (tightened counterclockwise after adjustment). When the cabinet door 45 is closed (see...), Figure 4 The push rod 38 presses against the elastic telescopic head of the push rod valve 12, putting the push rod valve 12 in an air-stopped state; when the box door 45 is opened (see... Figure 2 and Figure 3The elastic telescopic head of the top rod valve 12 automatically extends and resets, enabling automatic air supply. A switch lock 47 is fixed above the outer side of the door 45. When the door 45 is closed, pressing the switch lock 47 causes the internal fixing piece 34 to slide out of the slot 35, instantly separating the door 45 from the body 25. Simultaneously, two push-pull spring boosters 46 (fixed to the body 25) below the outer side of the door 45 quickly pull open the door 45, enabling assisted flipping opening. A buffer pad 48 (fixed to the body 25) is located below the spring boosters 46 to absorb the opening impact energy and protect the door 45. When closing the door 45, use one hand to forcefully close the door 45 while simultaneously pressing the spring piece on the switch lock 47 with the other hand, causing the fixing piece 34 to engage with the slot 35 and lock. During the opening of the door 45, the mask 32 automatically slides off the mask hook 33 under the action of gravity and centrifugal force, facilitating quick wearing by the user.

[0042] The structure of sub-tank 2 is basically the same as that of main tank 1, including similar air and water circuits, but it omits the drinking water purification device 39 and related connecting pipes (such as corrugated water pipe 10), and the purified water introduced directly from main tank 1 is used separately. The air circuit inlet is also equipped with a drain valve 7 for independent discharge.

[0043] The device is used as follows: First, connect the external compressed air pipe 3 and the external water supply pipe 4 to the external air source and water source, respectively. In an emergency, press the switch lock 47 of the main box 1 or the sub-box 2. The box door 45 will separate and quickly flip open under the action of the spring booster 46. The top rod valve 12 will reset and automatically supply air, and the mask 32 will automatically slide down. After the user puts on the mask 32, they can adjust the breathing flow by rotating the fourth shut-off valve 30. When water is needed, open the first shut-off valve 13 and drink through the drinking pipe 14. The air pressure sensor 18 monitors the air circuit pressure in real time and transmits it to the ground platform through the coal mine monitoring substation 50 to realize device positioning and status judgment. During routine inspections, open the sewage discharge pipe valve 7 to discharge sewage. The air circuit flow is as follows. Figure 5 The air source enters the main chamber 1 via external compressed air pipe 3, branching to the drain valve 7 and the main air path. The main air path is split via the top rod valve 12, one path to the air pressure sensor 18, and the other path to the gas pressure reduction and purification device 28 and the mask 32, and then to the distribution chamber 2 via compressed air connecting pipe 5. The water path flow is shown below. Figure 6 Water enters the main tank 1 through the external water supply pipe 4, is purified by the water pressure reducer 20 and the drinking water purification device 39, is then diverted to the drinking water pipe 14, and then to the sub-tank 2 through the water supply connection pipe 6.

[0044] This embodiment, through its segmented combination structure, enables simultaneous use by 6 people (each chamber contains 3 sets of breathing components), with an opening time of less than 1 second and an air supply response time of less than 1 second, greatly improving emergency efficiency.

[0045] Example 2 This embodiment expands upon Embodiment 1, providing a multi-combination, segmented, box-type compressed air and water supply self-rescue device suitable for scenarios with more people (e.g., 9 or more). Specifically, the device includes a main box 1 and two sub-boxes 2 (which can be expanded to more as needed). The right side of the main box 1 is connected to the first sub-box 2 via a compressed air connection pipe 5 and a water supply connection pipe 6. The right side of the first sub-box 2 is then connected to the second sub-box 2 via another set of compressed air connection pipes 5 and water supply connection pipes 6, forming a three-box series structure. Each box has 3 sets of breathing components, for a total of 9 sets, but the overall arrangement is dispersed to further reduce crowding.

[0046] The main box 1 has the same structure as in Embodiment 1, including a complete gas supply section (with a drain valve 7, a top rod valve 12, a wind pressure sensor 18, a gas pressure reducing and purification device 28, etc.), a water supply section (with a water supply pressure reducer 20, a drinking water purification device 39, etc.), and a quick-opening mechanism for the box door. Each sub-box 2 also has the same structure as the sub-box in Embodiment 1, omitting the drinking water purification device 39, but each sub-box 2 has an independent drain valve 7 and a wind pressure sensor 18 at its inlet, enabling independent monitoring and discharge. The connection method is as follows: the quick-connect male connector 40 on the right side of the main box 1 is connected to the quick-connect male connector 40 on the left side of the first sub-box 2 via the compressed air connection pipe 5 and the water supply connection pipe 6. The quick-connect male connector 40 on the right side of the first sub-box 2 is then connected to the quick-connect male connector 40 on the left side of the second sub-box 2, ensuring that gas and drinking water are transported in series without leakage.

[0047] To adapt to pure gas scenarios, this embodiment can also be modified into a pure gas structure, omitting all water supply-related components (external water supply pipe 4, water supply connection pipe 6, water pressure reducer 20, drinking water purification device 39, water pressure gauge 8, first shut-off valve 13, drinking water pipe 14, metal water pipe 43, corrugated water pipe 10, etc.), retaining only the air supply section and the quick-opening mechanism of the chamber door. In this case, the main chamber 1 and the sub-chamber 2 are connected in series only through the compressed air connection pipe 5, suitable for short-term emergency breathing situations where drinking water is not required. The chamber door 45 opening mechanism, automatic air supply, and automatic mask deployment function of the mask 32 remain unchanged.

[0048] The method of using this device is similar to that of Embodiment 1, but it is extended to multi-box operation: connect the external compressed air pipe 3 (and the external water supply pipe 4, if it is not a pure air structure) to the main box 1; users can disperse to each box and press their respective switch lock 47 to open the box door 45 to achieve independent automatic air supply and adjustment; the wind pressure sensor 18 of each box transmits signals independently, which facilitates accurate ground positioning of multiple emergency points. During routine inspections, open the drain valve 7 of each box one by one to discharge. The air and water circuit processes are the same as in Embodiment 1, but the paths are extended to multiple sub-boxes 2.

[0049] This embodiment, through multi-box expansion, enables simultaneous use by 9 or more people, making it suitable for long-distance tunnel escape relay and further enhancing the flexibility and reliability of the device.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
