Description

Technical Field

[0001] This invention relates to the field of self-rescue device technology, and more specifically, to a self-rescue device supply valve, an oxygen self-rescue device, protective equipment, and a refuge system. Background Technology

[0002] In recent years, with the accelerated growth of my country's energy production, safe and efficient coal mining is crucial to ensuring national energy security. As shallow coal seams in my country are gradually depleted, coal mining has entered the deep mining stage. Due to the complex geological conditions of deep coal seams, the obvious characteristics of high stress and high gas content, and the high porosity and natural gas content of oil and gas layers, the threat of coal and rock dynamic disasters is becoming increasingly serious. As a personal protective breathing device, the oxygen self-rescue device can provide workers with sufficient oxygen for a certain period of time, ensuring the health and safety of underground workers. It is one of the essential self-rescue devices for coal miners.

[0003] Currently, the available types of self-rescue devices include compressed oxygen self-rescue devices and chemical oxygen self-rescue devices.

[0004] (1) The compressed oxygen self-rescue device, also known as the isolated compressed oxygen self-rescue device, is a reusable self-rescue and escape device that uses high-pressure compressed oxygen as the oxygen source. It is mainly used in coal mines or ordinary atmospheric pressure work environments when there is a toxic and harmful gas outburst or oxygen deficiency and asphyxiation disaster. The human respiratory system is isolated from the outside world, and the instrument and the human respiratory system form an internal circulation.

[0005] (2) The chemical oxygen self-rescue device uses a canister containing potassium superoxide or sodium superoxide oxygen-generating agent as its core. It uses a chemical reaction to generate oxygen. It usually uses solid chemical substances or chemical agents to generate oxygen supply. When a person's mouth is connected to the mouthpiece (mask) of the self-rescue device, the person's respiratory system forms a closed system with the airway and canister of the entire self-rescue device, and the person's respiratory system is also isolated from the external gas.

[0006] The oxygen self-rescue device includes an interconnected supply valve and an oxygen tank. The supply valve of the self-rescue device is generally opened or closed by manually turning a knob, and the opening degree of the supply valve is adjusted to regulate the oxygen delivery rate. It can be seen that the existing self-rescue device supply valve has the following disadvantages: the existing self-rescue device supply valve cannot provide the oxygen demand of the human body under different exercise states, and it lacks the ability to achieve precise control and automatic supply of the self-rescue device.

[0007] In related technologies, automatic replenishment supply valves are disclosed, for example:

[0008] In the first related technology, an independent supply valve for a compressed oxygen self-rescue device is disclosed. It includes a lower housing with an air inlet, inside which a supply diaphragm with a metal insert is placed. An air inlet cap with an air source interface, a supply port, and a metering port is screwed onto a valve body back cap. An O-ring is placed on the valve body back cap, which is then fixed to an upper housing with an air outlet by the air inlet cap and valve body screws. A valve stem with a rubber sealing gasket is fitted with an adjusting spring, which passes through the valve body and is secured with a nut to a lever with a shaft and a washer. The upper and lower housings are then fastened together with screws. This design requires both a diaphragm and a lever to achieve automatic oxygen supply through their interaction, making the valve structure and automatic supply process complex. Furthermore, the automatic supply of this valve is easily affected by the diaphragm's elasticity, resulting in poor reliability.

[0009] In the second related technology, a technical solution is disclosed that by setting a first microcomputer and a pressure sensor on the supply valve, the first microcomputer can directly control the opening degree of the automatic valve according to the detection result of the pressure sensor. Although this solution solves the problem of complex structure and automatic replenishment process in the first related technology, if the first microcomputer is subjected to electromagnetic interference, it is easy for the first microcomputer to fail to control the opening degree of the automatic valve correctly, making its control effect unreliable.

With the installation of the refuge system of this application, ground personnel can provide critical guidance to underground personnel through a server, improving the survival rate of personnel in the event of a coal mine disaster. Furthermore, the second control component is connected to the first control component of the self-rescue device supply valve, so that the first control component transmits the air pressure detected by the first detection component of the self-rescue device supply valve to the second control component, so that the second control component records the air pressure detected by the first detection component. This further ensures the reliability of the self-rescue device supply valve and facilitates the control of the first control component. Attached Figure Description

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] Please refer to Figure 1 and Figure 2This invention provides a self-rescue device supply valve, comprising: a mounting housing 1 having an oxygen delivery channel 100; a detection assembly 2 including a first detection component 21 installed within the oxygen delivery channel 100 to detect the air pressure within the oxygen delivery channel 100; a first control valve 101 disposed within the oxygen delivery channel 100; and a first control assembly 3 mounted on the mounting housing 1 and located outside the oxygen delivery channel 100, the first control assembly 3 being connected to the detection assembly 2 and the first control valve 101 respectively to receive detection signals. The test results of component 2 are used to control the opening of the first control valve 101 to adjust the oxygen delivery rate of the oxygen delivery channel 100. The second control valve 102 is arranged at intervals with the first control valve 101. The second control valve 102 includes a valve seat 1020 and a valve core 1021 connected to each other. The valve seat 1020 is located in the oxygen delivery channel. The valve core 1021 is movably inserted into the valve seat 1020. The valve core 1021 has an operating part 1022 located on the outside of the mounting housing 1 to adjust the opening of the valve seat 1020 by operating the operating part 1022. With the above settings, the first control component 3 directly controls the opening degree of the automatic valve based on the detection result of the first detection component 21. This simplifies the control process of the self-rescue device supply valve. Furthermore, this application also provides a second control valve 102. When the first control component 3 receives electromagnetic interference and cannot accurately control the first control valve 101, the first control valve is fully opened, and the opening degree of the second control valve is adjusted by the operation unit 1022 to improve the reliability of the self-rescue device supply valve.

[0056] In this application, the detection component 2 includes a second detection element 22, which is disposed within the oxygen delivery channel 100 to detect the air pressure within the oxygen delivery channel 100. The second detection element 22 is connected to a first control valve 101 to jointly control the opening degree of the first control valve 101 based on the detection results of the first detection element 21 and the second detection element 22. The first detection element 21 and the second detection element 22 are spaced apart. This arrangement allows the detection results of the first detection element 21 and the second detection element 22 to corroborate each other, thereby improving the accuracy of the air pressure detection within the oxygen delivery channel 100.

[0057] In this application, the first detection component 21 is a pressure sensor; and / or the second detection component 22 is an impeller-type wind pressure measuring device.

[0058] like Figure 1As shown, the first detection component 21 and the second detection component 22 are both located on one side of the first control valve 101, and the second control valve 102 is located on the other side of the first control valve 101. This makes the structural arrangement of the first detection component 21, the second detection component 22, the first control valve 101, and the second control valve 102 reasonable.

[0059] In this application, the mounting housing 1 includes a mounting groove, and the first control component 3 includes a first microcomputer 31 and a first battery 32. The first microcomputer 31 is installed in the mounting groove, which has a bottom wall. The projection of the first microcomputer 31 on the bottom wall coincides with the projection of the detection component 2 on the bottom wall, thus facilitating the connection between the first microcomputer 31 and the detection component 2 and making the structure between the first microcomputer 31 and the detection component 2 compact. The first battery 32 is installed in the mounting groove and located on one side of the first microcomputer 31. The first battery 32 is connected to the first microcomputer 31 to charge the first microcomputer 31. Thus, both the first battery 32 and the first microcomputer 31 are set in the mounting groove, facilitating the connection between the first battery 32 and the first microcomputer 31 and making the structure between the first battery 32 and the first microcomputer 31 compact.

[0060] In this application, the first control component 3 includes a reset button 33, which is connected to the first microcomputer 31. The reset button 33 disconnects the circuit between the first control valve 101 and the first microcomputer 31, and sets the first control valve 101 to its maximum opening. Thus, when the first control component 3 receives electromagnetic interference and cannot accurately control the first control valve 101, pressing the reset button 33 disconnects the connection between the first control valve 101 and the first microcomputer 31, preventing the first microcomputer 31 from erroneously controlling the first control valve 101 under electromagnetic interference, further ensuring the reliability of the self-rescue device supply valve.

[0061] Optionally, pressing the reset button 33 controls the first microcomputer 31 to shut down, thereby disconnecting the circuit between the first control valve 101 and the first microcomputer 31 and severing the connection between the first control valve 101 and the first microcomputer 31; or, the first microcomputer 31 and the first control valve 101 have a switching component, and pressing the reset button 33 controls the first microcomputer 31 to open the switching component, thereby disconnecting the circuit between the first microcomputer 31 and the first control valve 101.

[0062] Optionally, after pressing the reset button 33, the first microcomputer 31 first controls the first control valve 101 to be at its maximum opening, and then disconnects the circuit between the first microcomputer 31 and the first control valve 101; or, when the reset button 33 is pressed, the first microcomputer 31 detects that the first control valve 101 is at its maximum opening, and disconnects the circuit between the first microcomputer 31 and the first control valve 101.

[0063] In this application, the self-rescue device supply valve includes an emergency light 4, which is mounted on the mounting housing 1 and connected to a first control component 3 to control the emergency light 4 to open or close. The emergency light 4 is disposed adjacent to a first battery 32, which is connected to the emergency light 4 to supply power. This facilitates the connection between the emergency light 4 and the first battery 32, resulting in a compact structure between them. Furthermore, by installing an emergency light on the self-rescue device supply valve, emergency lighting can be provided to underground workers in complex and dark disaster environments, facilitating observation of the surrounding conditions and further improving the reliability of the self-rescue device supply valve.

[0064] In this application, the self-rescue device supply valve includes a first explosion-proof cotton 300 and a protective cover 301. The protective cover 301 covers the opening of the mounting groove, and the first explosion-proof cotton 300 is located between the first control component 3 and the protective cover 301. In this way, the first control component 3 can be protected to ensure that the first control component 3 can reliably control the first control valve 101.

[0065] The existing oxygen self-rescue device uses a supply valve with a working pressure of only 20MPa, which restricts the increase of oxygen storage capacity, reduces the safe working time of the self-rescue device, and is not conducive to the effective escape of underground workers.

[0066] In this application, the housing 1 is made of carbon fiber metal composite material, which can increase the working pressure of the self-rescue device supply valve. When the working pressure of the self-rescue device supply valve increases, the gas (oxygen) in the self-rescue device's storage tank will be compressed more tightly, thereby increasing the oxygen storage capacity of the storage tank. This means that the self-rescue device can provide oxygen supply for a longer period of time, thereby increasing the user's survival time in an emergency.

[0067] In the embodiments of this application, the self-rescue device supply valve can achieve a test water pressure of 50MPa and a working pressure of 30MPa.

[0068] Optionally, the impeller-type wind pressure measuring instrument includes a rotatably disposed impeller, and the impeller and the first detection element 21 are disposed at intervals along the width of the oxygen delivery channel 100.

[0069] like Figure 2 As shown, the mounting housing 1 includes a first housing 110 and a second housing 120 that are connected to each other. The first housing 110 and the second housing 120 form an oxygen delivery channel 100. The first control component 3 and the detection component 2 are both mounted on the first housing 110.

[0070] The width direction of the oxygen delivery channel 100 is perpendicular to the gas flow direction of the oxygen delivery channel 100, and the width direction of the oxygen delivery channel 100 is perpendicular to the distribution direction of the first housing 110 and the second housing 120.

[0071] Specifically, the first housing 110 has a first groove, and the second housing 120 has a second groove. The first housing 110 is inserted into the second groove so that the bottom wall of the first groove and the second groove form an oxygen delivery channel 100.

[0072] like Figure 2 As shown, the self-rescue device supply valve of the present invention further includes a fixing strip 111 and a sealing gasket 112. The inner sidewall of the second groove portion and the outer sidewall of the first groove portion are spaced apart to form a first sealing gap. The fixing strip 111 is located in the first sealing gap and at the opening of the second groove portion. At least a portion of the sealing gasket 112 is located in the first sealing gap and at the side of the fixing strip 111 near the bottom wall of the second groove portion.

[0073] Specifically, the sealing gasket 112 includes a first sealing section and a second sealing section. The first sealing section is located within a first sealing gap. One end of the first groove portion near the bottom wall of the second groove portion is spaced apart from the bottom wall of the second groove portion to form a second sealing gap. The second sealing section is located within the second sealing gap, which can improve the sealing effect.

[0074] In this application, the first sealing section and the second sealing section are connected to each other, so as to protect the corners of the first housing 110; and / or, the first sealing section and the second sealing section are arranged perpendicularly to accommodate the structure of the corners of the first housing 110.

[0075] In this application, the first detection component 21 is installed on the first housing 110 and located in the oxygen delivery channel 100. The first detection component 21 can transmit the pressure signal to the first microcomputer. The first detection component 21 is made of single crystal silicon, which has the advantages of high accuracy ±0.075% and high stability, thus ensuring the control accuracy and reliability of the first control valve 101.

[0076] The impeller-type wind pressure measuring instrument (second detection component 22) is located inside the first housing. The impeller-type wind pressure measuring instrument includes an impeller (including blades). It monitors the impeller speed value and transmits the impeller speed value to the first microcomputer. The first microcomputer calculates the wind pressure by combining it with Bernoulli's equation. Together with the first detection component 21, the second detection component 22 ensures the control accuracy and reliability of the first control valve 101.

[0077] The present invention also provides an oxygen self-rescue device, comprising: the aforementioned self-rescue device supply valve 13; an air source connected to one end of the oxygen delivery channel 100 of the self-rescue device supply valve; an outlet hose connected to the other end of the oxygen delivery channel 100; and a face mask 12 connected to the outlet hose. The provision of the aforementioned self-rescue device supply valve 13 improves the reliability of the oxygen self-rescue device.

[0078] Specifically, the mounting housing 1 of this application is made of carbon fiber metal composite material, which increases the gas storage capacity of the gas source and can provide oxygen supply for a longer period of time, thereby increasing the user's survival time in emergency situations and further improving the reliability of the oxygen self-rescue device.

[0079] In this application, the mounting housing 1 of the self-rescue device supply valve 13 includes a first interface 130 and a second interface 140 that communicate with the oxygen supply channel 100. The first interface 130 and the second interface 140 are located at the two ends of the oxygen supply channel 100, respectively. The first interface 130 is connected to the gas source, and the second interface 140 is connected to the air outlet hose.

[0080] Specifically, the gas source includes a gas storage tank, and the first interface 130 is connected to the gas storage tank through a connecting pipe, which is threadedly connected to the first interface 130.

[0082] Specifically, the air outlet hose is inserted into the second interface 140, and the inner wall of the second interface 140 is interference-fitted with the outer wall of the air outlet hose.

[0083] In this application, the oxygen self-rescue device also includes an air supply bag, which is connected to an air supply hose.

[0084] Please refer to Figures 3 to 6The present invention also provides protective equipment, including: the aforementioned oxygen self-rescuer; a wearable component 5 for human wear, wherein the self-rescuer supply valve of the oxygen self-rescuer is installed on the wearable component 5; and a fire extinguishing component 6, which includes a fire extinguishing chamber 60 disposed on the wearable component 5. The fire extinguishing chamber 60 has a spray hole 600 and is used to hold carbon dioxide hydrate. When the temperature rises, the carbon dioxide hydrate decomposes into carbon dioxide gas, increasing the pressure inside the fire extinguishing chamber 60, causing the carbon dioxide gas to be ejected from the spray hole 600. With the above configuration, when a fire occurs while working underground, the carbon dioxide hydrate in the fire extinguishing chamber 60 decomposes into carbon dioxide gas, increasing the pressure inside the fire extinguishing chamber 60, causing the carbon dioxide gas to be ejected from the spray hole 600 for fire extinguishing. Simultaneously, the mask of the oxygen self-rescuer can be used to cover the mouth and nose to ensure normal breathing. Thus, the combination of the protective equipment and the oxygen self-rescuer improves the reliability and safety of underground workers.

[0085] In an embodiment of this application, the fire extinguishing component 6 includes a shielding member movably disposed at the spray hole 600 to open or close the spray hole 600. This prevents carbon dioxide hydrate from leaking out of the spray hole during normal operation.

[0086] To enable the shielding component to open or close the injection orifice, the shielding component can optionally be an inflatable gas bladder used to store inert gas. In the event of an explosion, the inflatable gas bladder will burst, opening the injection orifice 600. Alternatively, the shielding component can be a baffle plate movably disposed at the injection orifice 600. Or, the shielding component can be a baffle plate rotatably disposed at the injection orifice 600. This application utilizes a baffle plate to facilitate the reuse of the shielding component.

[0087] In the embodiments of this application, in order to achieve automatic control of the shield, when the shielding component is a shield, the fire extinguishing assembly 6 includes: a first driving component, which is disposed inside the wearable assembly 5 to protect the first driving component, and is drivenly connected to the shield to drive the shield to open or close; and a third detection component, which is disposed inside the fire extinguishing chamber 60 to detect the pressure inside the fire extinguishing chamber 60, and is connected to the first driving component to control the first driving component to drive the shield to move according to the detection result of the third detection component.

[0088] Optionally, the first driving component is an electric push rod or a cylinder; or, the first driving component is a drive motor.

[0089] like Figure 3 and Figure 4As shown, the wearable assembly 5 includes a first wearable component and a second wearable component disposed opposite to each other, forming a wearable space for accommodating a human body. Both the first and second wearable components include: an inner wearable layer 510, an explosion-proof layer 520, and an outer wearable layer 530. The explosion-proof layer 520 is located between the inner wearable layer 510 and the outer wearable layer 530, and the inner wearable layer 510 and the outer wearable layer 530 are interconnected. The outer wearable layer 530 of the first wearable component and the outer wearable layer of the second wearable component... 530 is movably connected to open the outer layer 530 of the wearable device, exposing the explosion-proof layer 520, thereby improving the explosion-proof effect of the explosion-proof layer 520; the inner layer of the first wearable device and the inner layer 510 of the second wearable device are interconnected; the explosion-proof layer 520 of the first wearable device and the explosion-proof layer 520 of the second wearable device are interconnected; wherein, the fire extinguishing component 6 is disposed on the inner layer 510, the explosion-proof layer 520 and the outer layer 530 of the wearable device, and the fire extinguishing component 6 is disposed on the first wearable device and / or the second wearable device. By incorporating the inner layer 510, the explosion-proof layer 520, and the outer layer 530, the impact resistance of the protective equipment is enhanced in the event of an explosion underground. Furthermore, opening the outer layer 530 improves the explosion-proof effect of the explosion-proof layer 520. In addition, the combined use of the inner layer 510, the explosion-proof layer 520, the outer layer 530, and the fire extinguishing component 6 enables the protective equipment to possess both explosion-proof and fire-extinguishing functions. This improves the reliability of the protective equipment in the event of an explosion and increases the survival rate of the personnel.

[0090] Specifically, the wearable component 5 includes an elastic element 540, the two ends of which are connected to the explosion-proof layer 520 and the inner wearable layer 510, respectively, thereby further improving the impact resistance of the protective equipment.

[0091] Preferably, there are multiple elastic elements 540, which are evenly distributed between the explosion-proof layer 520 and the inner wear layer 510 to further improve the impact resistance of the protective equipment. Among them, the elastic element 540 is a spring.

[0093] In the embodiments of this application, the impact resistance of the protective equipment is ensured by combining fiber-toughened ceramic composite material, carbon fiber resin composite material and elastic element 540.

Each of the first wearable structures 51, the second wearable structure 52, and each of the third wearable structures 53 has a first wearable component and a second wearable component. The fire extinguishing assembly 6 is disposed on the second wearable structure 52. Through the above arrangement, the protective equipment's protection range for the human body is ensured, minimizing the damage caused by underground disasters.

[0095] In embodiments of this application, the first wearable component of the second wearable structure 52 is worn on the chest of a human body, and the second wearable component of the second wearable structure 52 is worn on the back of a human body.

Each gas collection structure 7 includes a gas collection pump 70, which is connected to both the outside environment and the wearing space to introduce gas into the wearing space, causing the first and second wearing components to expand. The gas collection structures 7 located on the first and second wearing components of the second wearing structure 52 are spaced apart from the fire extinguishing components 6. Through this configuration, when encountering flooding underground, gas can be collected into the wearing space by the gas collection pump 70 to inflate the wearing components, ensuring that the wearing components can float in water, further improving the safety and reliability of workers operating underground.

[0100] In this application, at least one of the plurality of gas collection structures 7 includes a humidity sensor connected to a gas collection pump 70 to control the operating state of the gas collection pump 70 based on the detection result of the humidity sensor. Through this configuration, automatic gas collection by the gas collection structure 7 can be achieved, improving the reliability of the protective equipment.

[0101] Preferably, each of the multiple gas collection structures 7 is equipped with a humidity sensor to improve the reliability of the use of the multiple gas collection structures 7.

[0102] Since the area of ​​the second wearable structure 52 is relatively large, there are multiple air collection structures 7 on both the first wearable component and the second wearable component of the second wearable structure 52. These multiple air collection structures 7 are arranged at intervals, which improves the air collection effect on the second wearable structure 52.

The fourth wearable structure 54 has a first wearable component and a second wearable component. A fourth detection component is disposed on the fourth wearable structure 54, thus making the structural arrangement of the protective equipment reasonable. The fourth detection component is an impact force sensor.

[0109] In this application, the fourth detection component is installed on the fourth wearing structure 54, the fire extinguishing component 6 is installed on the second wearing structure 52, and the gas collection structure 7 is installed on the first wearing structure, the second wearing structure, and the third wearing structure. In this way, the fourth detection component will not affect the gas collection of the gas collection structure 7, nor will it affect the installation of the fire extinguishing component, so that the installation structure of the protective equipment is reasonably distributed.

The wearable connection portion 550 has two communicating openings 551, and the two communicating openings 551 are connected to the two third wearable structures 53 in a one-to-one correspondence.

[0111] Both connecting openings are arc-shaped structures to adapt the two connecting openings 551 to the connection structure of the third wearable structure 53.

[0112] In this application, the air collecting pump 70 is a miniature air pump.

[0113] Existing general-purpose protective equipment for underground mining consists of self-rescue devices. However, these devices only provide a safe breathing system for workers and cannot offer comprehensive and reliable safety protection in the event of gas explosions, mine fires, or floods. By incorporating the protective equipment described in this application, workers are provided with multifaceted protection during underground work through the wearing component 5, fire extinguishing component 6, and gas collection structure 7, thereby improving the reliability of the protective equipment.

[0114] When coal mine workers encounter disasters, the lack of emergency monitoring means restricts their rapid evacuation, and ground staff cannot provide crucial guidance to underground workers, thus reducing the survival rate of personnel during coal mine disasters.

[0137] In summary, during the specific implementation of the self-rescue device supply valve, oxygen self-rescue device, protective equipment, and refuge system of this application:

[0138] First, after the operator wears the protective equipment normally, the outer layer of the equipment will automatically open when encountering a gas shock wave caused by a gas explosion, and the internal elastic element 540 will change from a compressed state to a normal state, releasing the explosion-proof layer 520 to pop out in front of the person, thus acting as an explosion barrier. In the event of a fire, the high temperature environment will cause the carbon dioxide hydrate inside the carbon dioxide hydrate extinguishing chamber 60 to decompose rapidly, producing a large amount of high-pressure, high-concentration carbon dioxide, which is released from the spray hole 600, achieving a fire extinguishing effect. In the event of a flood, the gas collection structure 7 can use its gas collection pump 70 to quickly draw gas from the air into the space between the outer and inner layers of the equipment, increasing the buoyancy of the overall equipment and allowing the operator to float on the water surface.

[0139] Second, before using the oxygen self-rescuer, personnel should first wear a mask 12, then press the switch button 804 to open the refuge system, then inhale and press the calibration button. At this time, the first microcomputer will use Bernoulli's equation to calculate the wind pressure value from the rotation speed value collected by the impeller wind pressure measuring device, and combine it with the first detection component to obtain an accurate pressure signal. Then, the signal is transmitted to the second microcomputer 10 for recording. After that, the second microcomputer 10 can use the value as the opening and closing setting value of the first control valve and send the correct opening and closing status signal to the first control valve. Repeat the inhalation and exhalation test to see if the first control valve is working properly.

[0140] Third, during normal inhalation and exhalation, adjust the valve core of the second control valve 102 to a suitable oxygen delivery rate according to the person's lung capacity, and repeat the inhalation and exhalation test under different exercise states to see if the automatic supply valve (first control valve 101) is working properly.

[0141] Fourth, when personnel use the oxygen self-rescue device, the oxygen in the storage tank first enters the oxygen delivery channel 100 through the first interface, and then passes through the valve core of the second control valve, the first control valve 101 and the pressure sensor (first detection component 21) in sequence in the oxygen delivery channel 100, and finally enters the outlet hose and outlet bag through the second interface for personnel to inhale.

[0142] Fifth, when the calibration button 802 is pressed and the first control valve 101 cannot be controlled correctly, the person can press the reset button 33. At this time, the first control valve 101 will be forced to remain open, and the oxygen self-rescuer can only manually control the oxygen supply through the valve core of the second control valve.

[0143] Sixth, when personnel use the device normally, the detection radar (fifth detection component 9) will detect the damage to the roadway and locate the personnel in real time. The first and second sensor straps will monitor the personnel's heart rate, body temperature and other data in real time. When the human body is in an abnormal state, the data will be fed back to the second microcomputer 10 and transmitted to the ground server. The ground staff can contact the underground staff through the communication module 15 and the speaker 800 to obtain information on the disaster damage.

[0144] Seventh, when a disaster occurs underground, after the workers turn on the oxygen self-rescue device and put on the mask to breathe, the first microcomputer controls the emergency light 4 to light up, providing a bright self-rescue environment for the workers. Then, the workers can press the refuge button 803 to release the refuge signal to the second microcomputer 10 for processing. The second microcomputer 10 feeds back the refuge signal to the refuge module 16 and the communication module. The refuge module 16 displays the real-time optimal refuge route sent by the ground server on the display screen (display module 11). The communication module 15 will also emit refuge voice and broadcast it through the speaker hole 800.

[0145] Eighth, after the device is used, press switch button 804 to turn off the refuge system.

The valve core 1021 has an operating part 1022 located outside the mounting housing 1 to adjust the opening of the valve seat 1020 by operating the operating part 1022. With the above settings, the first control component 3 directly controls the opening degree of the automatic valve based on the detection result of the first detection component 21. This simplifies the control process of the self-rescue device supply valve. Furthermore, this application also provides a second control valve 102. When the first control component 3 receives electromagnetic interference and cannot accurately control the first control valve 101, the first control valve is fully opened, and the opening degree of the second control valve is adjusted by the operation unit 1022 to improve the reliability of the self-rescue device supply valve.

[0149] The reliability of the oxygen self-rescue device is improved by setting the self-rescue device supply valve 13 as described above.

[0150] The protective equipment of this application includes the aforementioned oxygen self-rescuer, wearable component 5, fire extinguishing component 6, and gas collection structure 7. When an explosion occurs while working underground, the carbon dioxide hydrate in the fire extinguishing chamber 60 decomposes into carbon dioxide gas upon heating, increasing the pressure inside the fire extinguishing chamber 60 so that the carbon dioxide gas is ejected from the injection port 600 for fire extinguishing. At the same time, the mask of the oxygen self-rescuer can be used to cover the mouth and nose to ensure normal breathing. In this way, the reliability and safety of underground workers are improved through the combination of protective equipment and oxygen self-rescuer. Through the setting of the gas collection structure 7, when a flood occurs underground, gas can be collected into the wearable component 5 so that the wearable component 5 can float on the water surface.

[0151] The refuge system of this application includes a fifth detection component 9, a second control component, and a supporting component. With the setting of the refuge system of this application, ground personnel can provide key guidance to underground personnel through a server, improving the survival rate of personnel in the event of a coal mine disaster. Furthermore, the second control component is connected to the first control component of the self-rescue device supply valve, so that the first control component transmits the air pressure detected by the first detection component 21 of the self-rescue device supply valve to the second control component, so that the second control component records the air pressure detected by the first detection component 21. This further ensures the reliability of the self-rescue device supply valve and facilitates the control of the first control component.

[0152] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
