Description

Technical Field

[0001] This invention belongs to the field of coal mine safety monitoring technology, specifically referring to a real-time monitoring device for an intelligent integrated management and control platform for coal mines. Background Technology

[0002] In the process of intelligent coal mine construction, the underground integrated management and control platform, as the central hub for underground safety production scheduling and risk perception, relies on front-end sensing equipment to continuously output stable and accurate underground environmental gas parameters. Methane and oxygen are two core monitoring indicators for underground operation safety: Methane is the main component of gas, with an explosion limit range of 5% to 16%, and it can easily accumulate in poorly ventilated areas of roadways, forming an explosion hazard; When the ambient oxygen concentration is below 19.5%, underground workers face the risk of asphyxiation, and the oxygen-deficient conditions will significantly reduce the detection accuracy of catalytic combustion gas sensors, directly causing the monitoring data to be distorted.

[0003] The existing intelligent integrated management and control platform for coal mines uses real-time monitoring equipment that has the following problems: First, in deep underground mining areas and ventilation dead zones, the ambient oxygen content is generally low. Catalytic combustion sensors produce negative measurement deviations due to insufficient combustion gas supply, and the methane concentration output by the equipment is lower than the actual concentration underground, forming a blind spot for safety monitoring. At the same time, the sensors work in a low-oxygen environment for a long time, and the incomplete oxidation of methane will cause continuous carbon buildup on the surface of the catalytic element, accelerating catalyst failure and shortening the overall service life of the sensor. Second, the existing monitoring equipment lacks a sensor-based catalytic element automatic carbon removal structure. The carbon layer on the surface of the element will block the gas to be tested from contacting the catalytic layer, continuously reducing the sensor's response sensitivity. The monitoring data uploaded to the control platform has long deviated from the actual gas concentration downhole, making it impossible for the platform to accurately assess the gas risk situation. Third, when the methane concentration at the monitoring point exceeds the standard, the existing equipment only has the function of uploading data and alarming. It cannot collect gas samples exceeding the standard for filtration and treatment, nor can it dilute and safely discharge local abnormal gas masses. The control platform lacks emergency linkage intervention means for front-end equipment, which makes it difficult to meet the needs of emergency response to underground gas. Therefore, it cannot meet the current demand for real-time monitoring equipment for intelligent integrated management and control platforms in coal mines. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of existing technologies, this solution provides a real-time monitoring device for an intelligent integrated management and control platform for coal mines. This device can supplement sufficient oxygen to the catalytic combustion sensor in the oxygen-deficient environment of deep underground mines, eliminating methane detection errors caused by low oxygen conditions. It can also periodically and automatically clean the carbon deposits on the surface of the sensor's sensitive elements and has the function of filtering and treating excessive methane gas samples.

[0005] The technical solution adopted in this plan is as follows: This plan proposes a real-time monitoring device for an intelligent integrated management and control platform for coal mines, including a detection cylinder, with an oxygen sensor and controller installed on the side wall of the detection cylinder; and movable frames are symmetrically arranged on both sides of the detection cylinder. A separate air supply mechanism, comprising a suction assembly and a filter assembly; The suction assembly is located at the end of the movable frame away from the detection cylinder, and includes a locking slide groove, a detachable tube frame, a rotating cylinder, and a gas valve. The air filtration assembly is disposed on the side wall of the detection cylinder and includes a filter frame fixed on the side of the detection cylinder near the moving frame, a filter cylinder installed on the outside of the filter frame, two layers of filter cotton arranged symmetrically in the filter cylinder, a modified activated carbon layer filled between the two layers of filter cotton, an air pump installed at the bottom of the filter cylinder, and a wound hose; the wound hose is wound around the outside of the rotating cylinder, and its two ends are respectively connected to the rotating cylinder and the air pump inlet. The self-complementary gas detection mechanism includes a gas storage component, a channel cutting component, a detection component, a carbon removal component, and a waste discharge component; The gas storage assembly includes a gas guide tube connected to the upper wall of the detection cylinder, the gas guide tube being through and having an upper inner diameter larger than a lower inner diameter; a gas storage hood being connected to the top of the gas guide tube; a delivery pipe connecting the filter cylinder and the gas storage hood; and a gas delivery electric valve being installed at the end of the delivery pipe near the filter cylinder. The cutting assembly is located inside the air guide tube and includes a first annular electromagnet, a second annular electromagnet, and an air inlet that are magnetically controlled. The detection assembly includes a catalytic combustion sensor installed at the bottom of the detection cylinder; The carbon removal assembly includes a carbon removal channel connected to the detection cylinder, a carbon removal electric valve, and a low-temperature hot air heater installed inside the carbon removal channel. The waste discharge assembly includes a waste discharge pipe connecting the carbon removal channel and the filter cartridge, and a waste discharge electric valve.

[0006] As a further preferred embodiment of the present invention, in the suction assembly, the tube holder is detachably snapped into the engagement groove; the rotating cylinder is rotatably mounted on the tube holder, and the wound hose is wrapped and stored on the outer wall of the rotating cylinder.

[0007] Preferably, the cutting channel assembly further includes: a dust filter plate fixed to the inner wall of the air guide cylinder near the detection cylinder, with multiple sets of dust filter screens penetrating the dust filter plate; a sealing block slidably assembled inside the air guide cylinder, with the two ends of the cutting channel spring connected to the dust filter plate and the sealing block respectively; an air supply port opened inside the sealing block, with a one-way air supply valve installed inside the air supply port; multiple sets of detection ports opened on the side wall of the air guide cylinder near the air storage hood; a first annular electromagnet fixed to the top wall of the air storage hood, and a second annular electromagnet fixed to the sealing block outside the air supply port; and a controller controlling the switching of the air supply port and the detection port by switching the energizing current direction of the two sets of electromagnets.

[0008] Preferably, the controller is connected to the first annular electromagnet, the second annular electromagnet, the catalytic combustion sensor, the oxygen sensor, and the air pump via electrical signals.

[0009] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, by setting up a separate gas supply mechanism and a self-replenishing gas measurement mechanism, oxygen-rich fresh air from the roadway can be extracted and sent into the detection cylinder under oxygen-deficient conditions in the mine, ensuring that the catalytic combustion sensor is in a standard oxygen concentration working environment, eliminating the negative deviation of methane measurement caused by low oxygen from the root, and the data uploaded to the integrated management and control platform can truly reflect the actual concentration of underground gas, avoiding the risk of monitoring blind spots. The equipment uses a controller to periodically open the carbon removal electric valve, which introduces a clean, oxygen-rich flow into the catalytic combustion sensor. The oxygen in the flow is used to oxidize and remove the carbon buildup on the surface of the element, restore the catalytic layer's responsiveness, and achieve automatic maintenance of the sensor without disassembly, thus extending the equipment's service life. The waste discharge electric valve and the carbon removal electric valve work in coordination at different times. When the gas level exceeds the standard, the local high-concentration gas cloud can be introduced into the filter cartridge, and after being adsorbed by the modified activated carbon layer, it can be safely discharged. This provides a pre-dilution treatment for the local accumulated gas and provides front-end emergency intervention capability for the integrated management and control platform.

The wound hose 39 is wound and stored on the outer wall of the rotating cylinder 7, and the two ends of the wound hose are respectively connected to the rotating cylinder 7 and the air inlet end of the air pump 38.

[0017] The gas storage assembly 15 includes a gas guide cylinder 16, a gas storage cover 17, a delivery pipe 18, and a gas delivery electric valve 19; the gas guide cylinder 16 is connected to the upper wall of the detection cylinder 1, and the inner diameter of the upper end of the gas guide cylinder 16 is larger than the inner diameter of the lower end; the gas storage cover 17 is connected and assembled on the top of the gas guide cylinder 16, the delivery pipe 18 connects the filter cylinder 11 and the gas storage cover 17, and the gas delivery electric valve 19 is installed on the section of the delivery pipe 18 near the filter cylinder 11; The cutting channel assembly 20 includes a dust filter plate 21, a dust filter screen 22, a sealing block 23, a cutting channel spring 24, an air inlet 26, a first annular electromagnet 27, a second annular electromagnet 28, a one-way air guide valve 34, and a detection port 37. The dust filter plate 21 is fixed to the inner wall of the air guide cylinder 16 near the detection cylinder 1, and multiple sets of dust filter screens 22 are opened through the dust filter plate 21. The sealing block 23 is slidably assembled in the upper inner cavity of the air guide cylinder 16, and the two ends of the cutting channel spring 24 are respectively connected to the dust filter plate 21 and the sealing block 23. The air inlet 26 is opened in the center of the sealing block 23, and a one-way air guide valve 34 is installed inside the air inlet 26. The first annular electromagnet 27 is fixed to the top wall of the air storage hood 17, and the second annular electromagnet 28 is fixed to the upper surface of the sealing block 23 outside the air inlet 26. Multiple sets of detection ports 37 are opened in annular shape on the side wall of the air guide cylinder 16 near the air storage hood 17. The detection assembly 29 includes a detection plate 30 and a catalytic combustion sensor 31; the detection plate 30 is threadedly fitted to the inner wall of the bottom of the detection cylinder 1, and the catalytic combustion sensor 31 is fixedly installed on the upper surface of the detection plate 30. The carbon removal component 40 includes a carbon removal channel 41, a carbon removal electric valve 42, and a low-temperature hot air heater 43. The carbon removal channel 41 is opened in the inner wall of the movable frame 2, and the lower end of the carbon removal channel 41 is connected to the bottom of the detection cylinder 1 through a through hole. The carbon removal electric valve 42 penetrates the outer wall of the movable frame 2 and is connected to the carbon removal channel 41. The low-temperature hot air heater 43 is fixedly assembled in the inner cavity of the carbon removal channel 41. The waste discharge assembly 25 includes a waste discharge electric valve 35 and a waste discharge pipe 36; the waste discharge electric valve 35 is connected to the upper wall of the carbon removal channel 41, and the waste discharge pipe 36 passes through the filter frame 10, with its two ends connected to the waste discharge electric valve 35 and the inner cavity of the filter cylinder 11, respectively.

[0018] The oxygen sensor 32 and the controller 33 are fixedly installed on the side wall of the detection cylinder 1 respectively; the controller 33 is electrically connected to the first annular electromagnet 27, the second annular electromagnet 28, the catalytic combustion sensor 31, the oxygen sensor 32, and the air pump 38.

[0019] In actual use, in the initial standby state: the cutting spring 24 is in the natural extension and pre-tightening state, the sealing block 23 blocks the detection port 37 downwards, and the air supply electric valve 19, the carbon removal electric valve 42, and the waste discharge electric valve 35 are all kept closed. Underground mobile deployment stage: The operator pushes the two mobile frames 2 on both sides and carries the detection tube 1 into the underground mining roadway; when the equipment moves to a point in the roadway with sufficient oxygen content and normal gas concentration, the pipe rack 6 is taken out from the locking slide 5 and fixed to the roadway ground; the mobile frame 2 continues to move the detection tube 1 to the deep area to be tested, and the rotating cylinder 7 rotates with the equipment to release the wound hose 39, completing the long-distance sampling pipeline deployment; Conventional downhole gas sampling and monitoring operation: After the equipment is started, the controller 33 supplies positive current to the first annular electromagnet 27 and the second annular electromagnet 28. The two sets of electromagnets form a state of attraction between opposite poles. The first annular electromagnet 27 attracts the second annular electromagnet 28 upward, which drives the sealing block 23 to slide upward along the gas guide cylinder 16 against the elastic force of the tangential spring 24. The detection port 37 is connected to the inner cavity of the gas guide cylinder 16. The downhole ambient gas enters the gas guide cylinder 16 through the detection port 37, passes through the dust filter 22 to filter dust and impurities, and then flows into the inner cavity of the detection cylinder 1, so that the gas composition in the cylinder is consistent with the downhole environment. The controller 33 simultaneously starts the catalytic combustion sensor 31 and the oxygen sensor 32 to collect downhole methane and oxygen concentration data in real time. The monitoring data is uploaded to the coal mine intelligent integrated management and control platform in real time. Emergency response to excessive methane concentration: When the catalytic combustion sensor 31 detects that the methane concentration exceeds the safety threshold, the controller 33 maintains the positive energization of the two sets of electromagnets, the sealing block 23 remains upward, the detection port 37 remains open, the controller 33 closes the gas supply electric valve 19, and simultaneously opens the waste discharge electric valve 35; the suction pump 38 extracts the excessive methane gas sample from the mine through the detection port 37 and sends it into the detection cylinder 1. The excessive gas flows into the filter cylinder 11 through the carbon removal channel 41 and the waste discharge pipe 36; after the gas passes through two layers of filter cotton 13 for dust removal and the modified activated carbon layer 12 for methane adsorption, it flows into the wound hose 39 and is finally safely discharged through the gas valve 8, reducing the local methane accumulation concentration; the equipment simultaneously uploads an excessive alarm signal to the integrated management platform, triggering the platform to link emergency procedures such as roadway ventilation and working face power outage; Underground deep oxygen deficiency and oxygen replenishment correction condition: When the oxygen sensor 32 detects that the ambient oxygen concentration is lower than the 19.5% oxygen deficiency threshold, the controller 33 switches the direction of the current of the two sets of electromagnets. The two sets of electromagnets form a state of like poles repulsion. The sealing block 23 slides down along the gas guide tube 16. The detection port 37 is blocked by the side wall of the sealing block. The gas storage hood 17 is connected to the gas replenishment port 26. The controller 33 opens the gas supply electric valve 19 and closes the waste discharge electric valve 35. The air pump 38 draws oxygen-enriched air from the roadway via the gas valve 8. The oxygen-enriched air is then sent to the filter cylinder 11 via the coiled hose 39. After passing through the filter cotton layer 13 and the modified activated carbon layer 12, the air is cleaned and purified. The clean oxygen-enriched air is then sent to the gas storage hood 17 via the delivery pipe 18. The oxygen-enriched air in the gas storage hood is then sent to the detection cylinder 1 via the gas supply port 26 and the one-way gas guide valve 34. This increases the oxygen concentration in the detection cylinder, ensuring that the catalytic combustion sensor has sufficient combustion support and eliminating the negative deviation in methane measurement caused by low oxygen. After the oxygen sensor 32 monitors the oxygen concentration in the cylinder and it returns to the safe standard range, the controller 33 restores the positive energization of the two sets of electromagnets. The sealing block 23 slides upward to open the detection port 37, and the equipment resumes normal downhole gas real-time sampling and monitoring. Automatic carbon removal maintenance of sensors: When oxygen sensor 32 determines that the downhole oxygen content meets the standard and catalytic combustion sensor 31 detects that the methane does not exceed the standard, controller 33 cuts off the power supply to the two sets of electromagnets. After the magnetic force disappears, the cutting spring 24 rebounds and pushes the sealing block 23 downward to block the detection port 37, cutting off the downhole environmental gas sampling path. The controller synchronously opens the air supply electric valve 19, the carbon removal electric valve 42, the air pump 38, and the low-temperature hot air heater 43; the air pump 38 draws in room temperature oxygen-rich air purified by the filter cartridge 11, and sends it into the carbon removal channel 41 through the carbon removal electric valve 42; the low-temperature hot air heater 43 gently heats the airflow, and the warm air blows on the surface of the catalytic combustion sensor 31, using the oxygen in the airflow to oxidize and remove the carbon deposits on the surface of the element. The waste gas containing impurities after blowing flows into the gas storage hood 17 through the air supply port 26 and the one-way air guide valve 34, and then flows back to the filter cartridge 11 along the conveying pipe 18. After secondary purification by the filter material, it is discharged through the wound hose 39 and the gas valve 8, completing the automatic carbon removal maintenance of the sensor. Equipment maintenance and replacement operation: After the performance of the catalytic combustion sensor 31 deteriorates after long-term use, the operator can unscrew the bottom detection plate 30 of the detection cylinder 1 in the well and directly take out the catalytic combustion sensor 31 to complete the replacement. After assembly, tighten the detection plate 30 to restore the gas circuit seal. When replacing the filter media, only the filter frame 10 needs to be disassembled to quickly replace the filter cotton layer 13 and the modified activated carbon layer 12, making downhole disassembly and maintenance convenient. After the equipment maintenance is completed, the above operation process can be repeated to continue downhole monitoring.
