Simultaneously, the control component 5 is connected to the gas detection component 2, the first collection component 3, and the second collection component 4, respectively. The control component 5 is used to acquire the detection results of the gas detection component 2 and control the gas flow between the gas detection component 2 and the first or second collection component 3. Specifically, in addition to acquiring the detection results of the gas detection component 2, the control component 5 can also control the connection / disconnection between the gas detection component 2 and the first collection component 3, and between the gas detection component 2 and the second collection component 4, according to a preset program.

By precisely controlling the gas flow, the control component 5 ensures the accuracy of the gas samples acquired by the gas detection component 2, improving detection accuracy and ensuring the reliability of the results. Simultaneously, through multi-point collection by the first and second collection components 3 and 4, the gas situation in the goaf and roadways can be monitored in real time, allowing for the timely detection of potential safety hazards and improving mine safety. Furthermore, the control component 5 can quickly respond to detection results and take timely measures to prevent accidents. In addition, integrating all components onto the housing 1 achieves an integrated design, resulting in a neat appearance, improved overall aesthetics, and ease of installation, inspection, and maintenance. It also enables automated control and detection, reducing manual intervention and improving operational convenience.

At least a portion of the control component 5 is installed in the installation space of the housing 1 and is connected to the gas detection component 2, the first collection component 3, and the second collection component 4, respectively. It is used to obtain the detection results of the gas detection component 2 and control the gas flow between the gas detection component 2 and the first collection component 3 or the second collection component 4. When it is necessary to detect the air in the goaf, the control unit 5 closes the connection between the second sampling unit 4 and the gas detection unit 2, and opens the connection between the first sampling unit 3 and the gas detection unit 2. The first sampling unit 3 then collects air from the goaf and transmits it to the gas detection unit 2 through its outlet.

The detection results are then fed back to the control unit 5. When it is necessary to detect the air in the roadway, the control unit 5 closes the connection between the first sampling unit 3 and the gas detection unit 2, and opens the connection between the second sampling unit 4 and the gas detection unit 2. The second sampling unit 4 then collects air from the roadway and transmits it to the gas detection unit 2 through its outlet. The gas detection unit 2 receives the air sample from the roadway, detects the air, and obtains data such as the concentration of at least one gas in the air. The detection results are then fed back to the control unit 5.

The control valve 51 can quickly switch gas flow paths, enabling rapid gas detection in the goaf and roadways, saving time. By precisely controlling the gas flow, the control valve 51 ensures the accuracy of the gas samples acquired by the gas detection component 2, improving detection accuracy.

The first air inlet 511 and the second air inlet 512 form the air inlet end of the control valve 51.

[0040] Optionally, the control valve 51 is a reversing solenoid valve, specifically a two-position three-way reversing solenoid valve.

[0041] Specifically, such as Figures 4 to 7 As shown, the control component 5 also includes a flow control assembly 52, at least a portion of which is installed within the installation space. The flow control assembly 52 is connected to both the first outlet of the control valve 51 and the inlet of the gas detection component 2. The flow control assembly 52 is used to measure and / or regulate the airflow entering the gas detection component 2. By employing this control method, the flow control assembly 52 can regulate the airflow entering the gas detection component 2, ensuring that the gas detection component 2 operates in its optimal working condition, thus improving the accuracy and reliability of detection. Furthermore, it allows for rapid adjustment of the gas flow, ensuring that the gas detection component 2 can quickly obtain a stable gas sample when switching detection paths, improving detection efficiency.

[0042] Furthermore, such as Figures 4 to 7 As shown, the flow control assembly 52 includes a flow regulating valve 521 and a flow measuring element 522. The flow regulating valve 521 is connected to the first outlet end of the control valve 51 and the inlet end of the gas detection component 2, respectively, to regulate the air flow rate entering the gas detection component 2. The flow measuring element 522 is connected to the outlet end of the flow regulating valve 521 and the inlet end of the gas detection component 2, respectively, to measure the air flow rate entering the gas detection component 2.

[0046] Specifically, such as Figures 4 to 7 As shown, the control component 5 also includes an air pump 53, which is installed within the installation space. The air pump 53 is connected to the first outlet of the control valve 51 and the inlet of the gas detection component 2. The air pump 53 is used to guide air from the goaf or roadway to the inlet of the gas detection component 2. With this structure, the air pump 53 can draw air from the roadway or goaf into the second collection component 4 or the first collection component 3, and then sequentially pass through the control valve 51, the air pump 53, and the flow control component 52 into the gas detection component 2. This allows the gas detection component 2 to quickly obtain gas samples, improving the detection speed. Furthermore, the air pump 53 can provide a stable airflow, ensuring consistent gas flow during each detection and reducing detection errors caused by airflow fluctuations.

[0049] Specifically, such as Figures 4 to 7 As shown, the control component 5 also includes a pressure detection element 54, which is connected to the second air outlet of the control valve 51. The pressure detection element 54 is used to monitor the pressure of the air entering the control valve 51. With this structural arrangement, the pressure detection element 54 allows for real-time monitoring of the air pressure, enabling timely detection of pressure anomalies, aiding in fault diagnosis and troubleshooting, and ensuring the long-term stable operation of the system. The pressure detection element 54 can monitor the gas pressure in real time, ensuring that the gas pressure remains within a safe range during the detection process, thus improving mine safety.

[0050] Furthermore, the pressure detection device 54 only detects the air pressure in the goaf. Its purpose is to monitor the gas pressure in the goaf, enabling timely detection of pressure anomalies, early warning, and prevention of safety accidents such as gas leaks or explosions. By monitoring the gas pressure in the goaf in real time, it ensures that the gas pressure remains within a safe range throughout the detection process, improving mine safety. In addition, the pressure detection device 54 can record the gas pressure data in the goaf, facilitating subsequent data analysis and historical comparison, helping mine managers understand the gas pressure change trends in the goaf.

[0051] Optionally, the second air outlet of the control valve 51 is connected to the first air inlet 511 of the control valve 51. When the air in the goaf enters the control valve 51 from the first air inlet 511, a portion of it enters the pressure detection element 54.

[0052] Optionally, the pressure sensing element 54 is a pressure transmitter.

[0053] Specifically, such as Figures 1 to 3As shown, the mine gas monitoring equipment also includes a temperature detection component 6, which has a first detection end and a second detection end. The first detection end is used to detect the temperature in the goaf, and the second detection end is used to detect the temperature in the roadway. The temperature detection component 6 is communicatively connected to the control component 5, and sends the detection results to the control component 5. This structural arrangement allows for real-time monitoring of the temperature in the goaf and roadway by the temperature detection component 6, enabling timely detection of temperature anomalies. By monitoring the temperature in the goaf and roadway in real time, it ensures that the temperature remains within a safe range during the detection process, thus improving mine safety. This enables early detection and warning of fire hazards in the goaf or roadway, effectively addressing the technical shortcomings in fire prediction and early warning in goaf or roadway areas. It provides coal mine management personnel with scientific monitoring data and reasonable management methods, providing sufficient time and space for early fire hazard management, effectively reducing or avoiding fire accidents and their losses, significantly improving fire prevention and monitoring technology, and having a positive impact on safe coal production, resulting in significant safety benefits. Furthermore, the temperature detection component 6 can quickly respond to temperature changes and take timely measures to prevent safety accidents caused by abnormal temperatures. Combined with the gas detection component 2 and the temperature detection component 6, comprehensive monitoring of gas and temperature in the goaf and roadways can be achieved, providing more comprehensive safety assurance. The control component 5 can integrate the data from gas and temperature detection for comprehensive analysis, improving the accuracy and reliability of monitoring.

[0054] Furthermore, the temperature detection component 6 can send the detection results to the controller of the control component 5. After receiving the results, the controller analyzes them and issues relevant instructions based on the analysis results, or sends the analyzed results and the results detected by the temperature detection component 6 to the terminal or other devices.

[0055] Furthermore, the temperature detection component 6 includes a first temperature sensor 61 and a second temperature sensor 62, wherein the first temperature sensor 61 forms a first detection end of the temperature detection component 6, and the second temperature sensor forms a second detection end of the temperature detection component 6.

[0056] Specifically, such as Figures 1 to 3As shown, the first acquisition component 3 includes a first filter 31. The first inlet 310 of the first filter 31 is connected to a pipeline at least partially located in the goaf area, and the first outlet 311 of the first filter 31 forms the outlet of the first acquisition component 3. The first filter 31 filters the air to be introduced into the gas detection component 2. This structural arrangement allows the first filter 31 to filter the air entering the gas detection component 2. This effectively prevents dust and particulate matter from entering the gas detection component 2, reducing wear and tear and extending its service life. Furthermore, by filtering out dust, particulate matter, and other impurities from the goaf air, the first filter 31 ensures the cleanliness of the gas entering the gas detection component 2, reducing detection errors caused by impurities. It also makes the filtered gas more stable, contributing to improved detection accuracy and reliability of the gas detection component 2. In addition, the first filter 31 prevents dust and particulate matter from clogging the gas flow path, ensuring smooth gas flow and improving the overall stability of the system.

[0057] Optionally, the first filter 31 can filter out dust, particulate matter, moisture, static electricity and other impurities in the air of the goaf.

[0058] Further, the first filter 31 includes: a first housing 312, a first drying filter element, a first dust removal element, and a first static eliminator element. The first housing 312 has a first mounting cavity, and a third observation window 313 is provided on the outer wall of the first housing 312. Simultaneously, the first drying filter element, the first dust removal element, and the first static eliminator element are disposed within the first mounting cavity. The collected air from the goaf enters the control valve 51 sequentially through the first drying filter element, the first dust removal element, and the first static eliminator element. The third observation window 313 allows observation of the status of the first drying filter element, the first dust removal element, and the first static eliminator element within the first mounting cavity, enabling timely replacement of the first drying filter element and / or the first dust removal element and / or the first static eliminator element based on the observed conditions.

[0059] The installation order of the first drying filter, the first dust removal component, and the first static electricity removal component can be adjusted arbitrarily according to the actual situation.

The second filter 41 filters the air entering the gas detection component 2. This structural arrangement allows the second filter 41 to filter the air entering the gas detection component 2. This effectively prevents dust and particulate matter from entering the gas detection component 2, reducing wear and tear and extending its service life. Furthermore, by filtering out dust, particulate matter, and other impurities from the air in the roadway, the second filter 41 ensures the cleanliness of the gas entering the gas detection component 2, reducing detection errors caused by impurities. It also makes the filtered gas more stable, contributing to improved detection accuracy and reliability of the gas detection component 2. In addition, the second filter 41 prevents dust and particulate matter from clogging the gas flow path, ensuring smooth gas flow and improving the overall stability of the system.

[0061] Further, the second filter 41 includes: a second housing 412, a second drying filter element, a second dust removal element, and a second antistatic element. The second housing 412 has a second mounting cavity, and a fourth observation window 413 is provided on the outer wall of the second housing 412. Simultaneously, the second drying filter element, the second dust removal element, and the second antistatic element are disposed within the second mounting cavity. The collected air from the tunnel sequentially enters the control valve 51 through the second drying filter element, the second dust removal element, and the second antistatic element. The fourth observation window 413 allows observation of the status of the second drying filter element, the second dust removal element, and the second antistatic element within the second mounting cavity, enabling timely replacement of the second drying filter element and / or the second dust removal element and / or the second antistatic element based on the observed conditions.

[0062] The installation order of the second drying filter, the second dust removal component, and the second static electricity elimination component can be adjusted arbitrarily according to the actual situation.

[0063] Specifically, the mine gas monitoring equipment also includes a sensing component, which is mounted on the housing 1. The sensing component is used to detect whether personnel are approaching within a preset distance range of the mine gas monitoring equipment. This structural arrangement, by incorporating the sensing component, allows for real-time monitoring of the surrounding area to prevent personnel from approaching, thereby improving safety.

[0064] Optionally, the sensing element is an infrared sensor (i.e., an electronic fence). Preferably, it is an infrared pyroelectric sensor.

[0065] Furthermore, the sensing component is connected to the controller of the control component 5 to send the sensing result to the controller of the control component 5, and the controller of the control component 5 sends relevant instructions based on the signal detected by the sensing component.

[0066] Specifically, such as Figures 1 to 3 As shown, the mine gas monitoring equipment also includes an alarm 100, which is mounted on the housing 1. The alarm 100 is connected to the controller of the control component 5, and the controller of the control component 5 controls whether the alarm 100 is activated. For example, when the sensing component detects that someone has entered the sensing range, the sensing component sends the detected result to the controller. After receiving the result, the controller sends an alarm command to the alarm 100, and the alarm 100 activates the alarm.

[0067] In this embodiment, the housing 1 includes a housing body 11 and a cover 12. The housing body 11 is provided with a placement groove 110, and the cover 12 is disposed on the housing body 11 to seal the placement groove 110.

[0069] Specifically, such as Figure 1 As shown, the mine gas monitoring equipment also includes: an operating component 8, which is mounted on the cover 12 and connected to the control component 5; the user can send commands to the control component 5 through the operating component 8.

[0070] Furthermore, the operating component 8 includes a first operating key 81 and a second operating key 82. The first operating key 81 is used to cancel the alarm. When the first operating key 81 is pressed as specified, the controller of the control component 5 receives the alarm cancellation command and controls the alarm 100 to stop. The second operating key 82 is used to control the mine gas monitoring equipment to start detection. When the second operating key 82 is pressed as specified, the controller of the control component 5 receives the start command, the mine gas monitoring equipment is turned on, and the controller of the control component 5 controls each component to enter the detection state.

[0071] Specifically, the mining gas monitoring equipment also includes multiple indicator lights 200, which are mounted on the cover 12. All multiple indicator lights 200 are connected to the controller of the control component 5, and the multiple indicator lights 200 illuminate in accordance with the instructions sent by the controller of the control component 5.

[0072] Optionally, the multiple indicator lights 200 include an air pump 53 operation indicator light, a power indicator light, a sensor transmitting indicator light, a receiving indicator light, and a sensing component operation indicator light, etc.

[0073] Specifically, the housing 1 is also provided with a vent valve 300, which is used to make the pressure of the housing 1 consistent with the pressure in the roadway.

[0074] Specifically, the mine gas monitoring equipment also includes a first communication interface 400 and a second communication interface 500. The first communication interface 400 is used to connect to a server terminal, and the controller of the control unit 5 sends the content received by the controller of the control unit 5 and the analysis results to the server terminal through the first communication interface 400, and / or the controller receives the content sent by the server terminal through the first communication interface 400. The second communication interface 500 is used to connect to an external display screen, and the controller of the control unit 5 sends the content received by the controller of the control unit 5 and the analysis results to the external display screen through the second communication interface 500. The external display screen displays accordingly based on the content sent by the controller of the control unit 5.

[0075] Specifically, the mining gas monitoring equipment also includes a power interface 600, through which the mining gas monitoring equipment can be connected to an external power source.

[0076] Specifically, the mining gas monitoring equipment is an intrinsically safe monitoring equipment for mining.

[0077] Optionally, the mine gas monitoring equipment is hung on a sealed cavity and located inside the roadway during use. The first air inlet 310 of the first filter 31 is connected to a pipeline, and the end of the pipeline away from the first air inlet 310 passes through the sealed wall and is located in the goaf. The first temperature sensor passes through the sealed wall and is installed in the goaf, and is connected to the controller via a wire.

[0078] Optionally, such as Figure 7 As shown, the specific operation process of the mine gas monitoring equipment for monitoring gas is as follows:

[0079] When it is necessary to detect the gas content in the air of the goaf, control valve 51 switches so that its first air inlet 511 is connected to its first air outlet, while its second air inlet 512 is closed. Simultaneously, the second air outlet and the first air inlet 511 of control valve 51 are normally open. After air pump 53 starts pumping air, the air from the goaf enters the first filter 31 through its first air inlet 310. After being filtered by the first filter 31, the air then passes through its first air outlet 311 and sequentially enters control valve 51 and pressure sensor 54. Pressure sensor 54 detects the air pressure in the goaf and feeds the result back to the controller. Meanwhile, the gas entering control valve 51 passes sequentially through air pump 53, flow regulating valve 521, and flow measuring device 522 before entering gas detection component 2. Gas detection component 2 detects various gases contained in the air in the goaf. The detected air is then discharged into the roadway or the gas negative pressure extraction pipeline within the roadway through the outlet end and exhaust pipe 9 of gas detection component 2. Furthermore, the results detected by gas detection component 2 are fed back to the controller, which analyzes the data and performs subsequent procedures.

[0080] When it is necessary to detect the gas content in the air within the tunnel, control valve 51 switches so that its second inlet 512 is connected to its first outlet, while the first inlet 511 is closed, thus the second outlet is also closed. After the air pump 53 starts pumping air, the air in the tunnel enters the second filter 41 through its second inlet 410. After being filtered by the second filter 41, the air then passes through its second outlet 411 and enters the control valve 51. It then passes through the air pump 53, flow regulating valve 521, and flow measuring device 522 before entering the gas detection component 2. The gas detection component 2 detects the various gases present in the air within the tunnel. The detected air is then discharged into the tunnel or into the gas negative pressure extraction pipeline within the tunnel through the outlet and exhaust pipe 9 of the gas detection component 2. Furthermore, the results detected by the gas detection component 2 are fed back to the controller, which analyzes the data and performs subsequent procedures.

[0081] For temperature detection, the first temperature sensor 61 and the second temperature sensor 62 will monitor the temperature of the goaf and the temperature in the roadway in real time, respectively, and feed the detected results back to the controller, which will analyze and perform subsequent procedures.
