Description

Technical Field

[0001] The present invention relates to the technical field of environmental detection, and in particular to an intelligent mobile key area environmental detection system for mining. Background Art

[0002] When working in the confined space underground in a mine, various harmful gases, such as methane, carbon monoxide, oxygen, and hydrogen sulfide, accumulate in the mine due to the closed space and poor ventilation. Therefore, it is crucial to conduct gas detection before entering the mine to work. During the underground coal mine environment monitoring, the coal mine inspectors carry portable gas detectors to conduct inspections underground and detect the gas environment data underground through the gas detectors.

[0003] Due to the extremely high concentration of solid particulate matter such as dust and coal slag in the mine environment, pollutants accumulate quickly on the filter surface of the gas detector, and the filters used in the gas detector are mostly needle filters, which are very easy to clog when used in dusty and humid environments. Once the filter is clogged, the suction force of the air pump will be weakened, and the sample gas in the test area cannot be effectively absorbed. At the same time, impurities in the sampled gas will enter the detection instrument, affecting the normal operation of the sensor and causing inaccurate test results. Therefore, the filter needs to be replaced frequently, and the cost of frequent filter replacement is high. If the filter is replaced during the detection process, gas leakage or infiltration of external pollutants will occur, which will directly affect the accuracy of the detection. Summary of the Invention

[0064] To facilitate understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0065] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0067] like Figures 1 to 4 As shown, the present application proposes an intelligent mobile key area environment detection system for mining, including a gas detector 100 and a filter chamber 110. The gas detector 100 is used to detect the gas concentration in the mine environment. The filter chamber 110 is fixed to the bottom of the gas detector 100. An air inlet cylinder 120 is fixed to the bottom of the filter chamber 110. The gas in the detection area enters the filter chamber 110 from the air inlet cylinder 120, and enters the interior of the gas detector 100 after being filtered by the filter chamber 110. A fine filter layer 111 is fixed near the gas detector 100 in the filter chamber 110, and a coarse filter layer 112 is fixed near the air inlet cylinder 120 in the filter chamber 110. That is to say, the detection gas passes through the coarse filter layer 112 and the fine filter layer 111 in sequence. The system also includes a cleaning component 200.

[0068] The cleaning assembly 200 includes a vent pipe 210 and an air intake pipe 220;

[0069] The vent pipe 210 is an annular tube and is fixed in the filter chamber 110 near the gas detector 100. The vent pipe 210 is located above the fine filter layer 111.

[0070] A plurality of gas capsules 211 are evenly fixed on the side of the ventilation tube 210 near the fine filter layer 111. One end of the gas capsule 211 extends into the ventilation tube 210. The connection between the gas capsule 211 and the ventilation tube 210 is airtight and fixed.

[0071] A striking block 212 is fixed to the free end of each gas bag 211. One end of the air inlet pipe 220 is connected to the air pump, which is fixed to the outer side of the filter chamber 110. The other end of the air inlet pipe 220 extends into the ventilation pipe 210.

[0072] The air inlet pipe 220 is used to inflate and deflate the air in the vent pipe 210 , causing the air bag 211 to repeatedly expand and contract, thereby driving the striking block 212 to repeatedly strike the fine filter layer 111 .

[0073] It is worth noting that the fine filter layer 111 can intercept dust particles of 0.2μm to 0.35μm, and the coarse filter layer 112 can intercept dust particles of 0.5㎜ to 1㎜, and the fine filter layer 111 is more easily clogged than the coarse filter layer 112. By repeatedly hitting the fine filter layer 111 with the hitting block 212, the intercepted dust can be knocked down, and the dust can fall through the coarse filter layer 112, reducing clogging.

[0074] Also included are wireless transceivers, display screens, and network switches;

[0075] The wireless transceiver and display screen are both installed at the inspection point under the mine. The gas detector 100 is electrically connected to the wireless transceiver through wireless signals. The gas detector 100 has auxiliary functions such as real-time time display, ambient temperature detection, stopwatch, etc., and can achieve real-time detection and real-time upload. The wireless transceiver is electrically connected to the network switch through the circuit. The system has functions such as data storage, query, printing, analysis and early warning.

[0076] It is worth mentioning that the gas detector 100 has a storage function. When the inspection point is not equipped with a wireless transceiver, the gas inspector can save the detection data manually, and then synchronize the saved detection data to the central station after going up the well.

[0077] A micro air pump 130 is fixed in the gas detector 100, an exhaust pipe 131 is fixed on the air inlet end of the micro air pump 130, and an air supply pipe 132 is fixed on the air outlet end of the micro air pump 130. A detection module 140 is fixed in the gas detector 100. The detection module 140 is used to detect the concentration of the gas. The free end of the air supply pipe 132 is connected to the detection module 140. An air outlet pipe 133 is fixed on the detection module 140, and the free end of the air outlet pipe 133 extends to the outside of the gas detector 100.

[0078] It is easy to understand that the micro air pump 130 is used to evacuate the air in the exhaust pipe 131, so that the gas in the detection area enters the filter chamber 110 from the air inlet cylinder 120, and after filtration, enters the air supply pipe 132 through the exhaust pipe 131, and the gas is sent into the detection module 140 through the air supply pipe 132, and then discharged from the air outlet pipe 133. The detection module 140 can detect methane, carbon monoxide, oxygen, hydrogen sulfide, ambient temperature, etc.

[0079] Specifically, if Figures 5 to 7 As shown, the fine filter layer 111 is provided with a through groove, in which a soft net 1111 is fixed. The mesh diameter of the soft net 1111 is the same as that of the fine filter layer 111, that is, the soft net 1111 can also intercept dust particles of 0.2 μm to 0.35 μm. A plurality of collision blocks 1112 are fixed on the soft net 1111 near the coarse filter layer 112;

[0080] A plurality of soft plates 114 are fixed inside the filter chamber 110. The soft plates 114 are located between the fine filter layer 111 and the coarse filter layer 112. A hammering plate 1141 is fixed to the free end of each soft plate 114. The hammering plate 1141 is located below the collision block 1112.

[0081] The striking block 212 is located above the soft net 1111 and is a rubber plate with a T-shaped cross section. When the striking block 212 strikes the fine filter layer 111 , it can drive the collision block 1112 to repeatedly strike the beating plate 1141 , and beat the coarse filter layer 112 through the beating plate 1141 .

[0082] It should be noted that the lower part of the beating block 212 penetrates into the soft net 1111, causing the soft net 1111 to deform and sink downward. At this time, the upper part of the beating block 212 can still collide with the fine filter layer 111, and the soft plate 114 has good elasticity. When the beating plate 1141 beats the coarse filter layer 112 downward, the gas bag 211 contracts and drives the beating block 212 to move upward. Due to the high elastic strength of the soft plate 114, the impact generated by the beating plate 1141 can react on the collision block 1112, and the gap left by the upward movement of the beating block 212 is used to hit the fine filter layer 111 and the soft net 1111 again, thereby further improving the cleaning efficiency.

[0083] Specifically, if Figures 5 to 7 As shown, a fixing frame 121 is fixed in the air inlet cylinder 120 near the coarse filter layer 112 . The fixing frame 121 takes up little space and does not affect the entry of gas. A streamer 122 is fixed on the fixing frame 121 away from the coarse filter layer 112 .

[0084] It is easy to understand that after the gas to be detected enters the air inlet cylinder 120, it comes into contact with the ribbon 122. The ribbon 122 swings under the influence of the airflow. The airflow in the laminar state becomes turbulent after coming into contact with the ribbon 122. This not only disperses the dust particles in the gas evenly and avoids excessive blockage in the area, but also increases the flow speed of the airflow and improves the efficiency of detection.

[0085] Specifically, if Figures 5 to 7 As shown, the fixing frame 121 is a hollow cylinder and is fixed in the air inlet cylinder 120 by a rectangular plate. The streamer 122 is an elliptical cylindrical rubber strip with a hollow interior. That is, gas can enter the space of the cylindrical structure of the streamer 122. The streamer 122 is connected to the interior of the fixing frame 121. That is, when air is taken into the fixing frame 121, the gas can enter the streamer 122.

[0086] An air duct 1211 is fixed to the side of the fixing frame 121 . One end of the air duct 1211 extends into the fixing frame 121 , and the other end of the air duct 1211 is connected to the air inlet pipe 220 .

[0087] It is easy to understand that when the air inlet pipe 220 is repeatedly inflated and deflated, the air guide pipe 1211 is also repeatedly inflated and deflated, thereby causing the streamer 122 to be repeatedly inflated and deflated. When air is taken into the streamer 122, the streamer 122 will expand and compress the gas in its space to be discharged. When the air is exhausted from the streamer 122, a negative pressure will be generated in its cylindrical space, and the gas in the air inlet cylinder 120 will be sucked into the cylindrical space. In this way, the flow rate of the airflow can be repeatedly disturbed more quickly, and the swing caused by the expansion and contraction of the streamer 122 can also disrupt the flow state of the surrounding airflow, further increasing the flow rate of the airflow and dispersing the dust impurities in the airflow.

[0088] In the above embodiment, a gas inspector carries a gas detector 100 while conducting an inspection in the mine. When the gas inspector arrives at the inspection point, the gas detector 100 uploads the detected environmental data, such as methane, carbon monoxide, oxygen, hydrogen sulfide, and ambient temperature, to the central station above the mine via a wireless transceiver and a switch, and displays each detected data on a display screen. This can improve the standardization and informatization of coal mines, and timely and effectively transmit the data detected by the gas inspector to on-site workers underground, effectively reducing or avoiding the occurrence of production safety accidents, and providing protection for coal mine production safety.

[0089] During the gas detection process, the gas inspector holds the gas detector 100 and always points the air inlet of the air cylinder 120 toward the ground. The micro air pump 130 is used to extract the gas in the detection area, so that the detection gas enters the filter chamber 110 from the air cylinder 120. At the same time, the air pump inflates and deflates the air inlet pipe 220, and the air guide pipe 1211 repeatedly inflates and deflates the streamer 122 to increase the flow rate of the air flow. When air is taken into the ventilation pipe 210, the gas bag 211 is inflated and drives the striking block 212 to quickly descend and strike the fine filter layer 111, and at the same time drives the beating plate 1141 to strike the coarse filter layer 112. This repeated movement can clean the fine filter layer 111 and the coarse filter layer 112 during the gas detection process, reduce blockage, and thus improve the quality of gas detection.

[0090] In some embodiments of the present application, Figures 5 to 7 As shown, a cleaning portion 230 is also included;

[0091] The cleaning unit 230 includes a sealing chamber 231 and a fixing plate 2321;

[0092] The sealing chamber 231 is fixed to the side of the filter chamber 110, the fixing plate 2321 is located in the sealing chamber 231, and the movable frame 232 is fixed to the side of the fixing plate 2321 away from the filter chamber 110;

[0093] The sealing chamber 231 has a through hole on its side, and the free end of the movable frame 232 extends out of the sealing chamber 231 through the through hole.

[0094] A cylindrical upper cleaning plate 233 is fixed to the other side of the fixed plate 2321 close to the filter chamber 110, and the upper cleaning plate 233 is located between the fine filter layer 111 and the coarse filter layer 112. Brushes are fixed to the top and bottom of the upper cleaning plate 233, one brush contacts the surface of the fine filter layer 111, and the other brush contacts the surface of the coarse filter layer 112.

[0095] A reserved groove is opened on one side of the filter chamber 110 close to the sealing chamber 231 , and a partition 116 is sealed in the reserved groove. The partition 116 is detachable, and the upper cleaning plate 233 can extend into the filter chamber 110 after the partition 116 is removed.

[0096] It is worth noting that when further cleaning the fine filter layer 111 and the coarse filter layer 112, the partition 116 is taken out and the movable frame 232 is pushed to push the upper cleaning plate 233 into the filter chamber 110. By moving the movable frame 232 back and forth, the fine filter layer 111 and the coarse filter layer 112 are further cleaned with a brush. There is no need to repeatedly disassemble the fine filter layer 111 and the coarse filter layer 112, thereby improving the cleaning efficiency and thus improving the efficiency of gas detection.

[0097] Specifically, if Figures 8 to 11As shown, the partition 116 is a semicircular plate, and a convex plate is fixed on its side. The convex plate is located outside the filter chamber 110. A groove is opened on the side of the filter chamber 110, and a limit plate 115 is embedded in the groove.

[0098] The limiting plate 115 is a semicircular plate with a protrusion fixed on its side. The protrusion is used to increase the contact force with the hand to facilitate the removal of the limiting plate 115, and its end surface contacts the end surface of the partition 116.

[0099] The filter chamber 110 is threadedly connected to a sealing cover 113 near the air inlet cylinder 120. The air inlet cylinder 120 is fixed on the sealing cover 113. The sealing cover 113 and the filter chamber 110 are sealed and can be removed by rotating the sealing cover 113.

[0100] It should be noted that the limit plate 115 is used to limit and fix the partition 116 to ensure that the partition 116 does not shift. When the partition 116 needs to be rotated to clean the fine filter layer 111 and the coarse filter layer 112, first buckle out the limit plate 115, and then rotate the convex plate to turn the partition 116 outward, which is convenient for cleaning and easy to operate.

[0101] In the above embodiment, after the gas detection is completed, the sealing cover 113 is first rotated and removed, the limit plate 115 is disassembled, and then the pull plate is pushed to rotate the partition 116 outward, and then the movable frame 232 is pushed to push the upper cleaning plate 233 into the filter chamber 110, and the brush on the upper cleaning plate 233 is used to clean the fine filter layer 111 and the coarse filter layer 112 at the same time. The impurities after cleaning are discharged outward, and there is no need to frequently disassemble the filter chamber 110 for cleaning, which improves the cleaning efficiency and ensures the quality of gas detection.

[0102] In some embodiments of the present application, Figures 12 to 14 As shown, a telescopic bag 1 2331 is fixed to the fixed plate 2321, and the upper cleaning plate 233 is a hollow cylinder and is slidably connected to the fixed plate 2321. The telescopic bag 1 2331 is located above the upper cleaning plate 233, and the upper cleaning plate 233 is detachably connected to the fixed plate 2321 by means of a buckle. In other words, the upper cleaning plate 233 and the fixed plate 2321 are detachable by means of a buckle.

[0103] A guide plate 2322 is fixed to the fixed plate 2321. A sliding groove is provided in the sealing chamber 231. The guide plate 2322 extends into the sliding groove. In this way, when the movable frame 232 pushes the fixed plate 2321, the guide plate 2322 can move horizontally in the sliding groove, and the fixed plate 2321 is supported and guided by the guide plate 2322.

[0104] The telescopic bag 1 2331 is used to push the upper cleaning plate 233 to move. The upper cleaning plate 233 is located above the fine filter layer 111.

[0105] A cylindrical cleaning box 234 is fixed in the middle of the fixing plate 2321. The cleaning box 234 is located between the fine filter layer 111 and the coarse filter layer 112. The sealed chamber 231 can be opened. A liquid injection port is provided on the cleaning box 234 to facilitate timely addition of cleaning liquid into the cleaning box 234.

[0106] The cleaning box 234 contains a cleaning liquid, which is an alkaline cleaning liquid that can better clean the coal powder in the fine filter layer 111 and the coarse filter layer 112. The cleaning liquid is used to clean the fine filter layer 111 and the coarse filter layer 112. A plurality of atomizing nozzles 2341 are fixed at both ends of the cleaning box 234.

[0107] A second telescopic bag 2351 is fixed to the fixed plate 2321 away from the upper cleaning plate 233. A cylindrical lower cleaning plate 235 is slidably connected to the fixed plate 2321. The second telescopic bag 2351 is located below the lower cleaning plate 235. The lower cleaning plate 235 is detachably connected to the fixed plate 2321 by a buckle. The lower cleaning plate 235 and the fixed plate 2321 are detachable by a slot buckle. A brush is fixed to the lower cleaning plate 235, and the lower cleaning plate 235 is located below the coarse filter layer 112.

[0108] The diameter of the upper cleaning plate 233 is equal to the diameter of the fine filter layer 111 , the diameter of the lower cleaning plate 235 is equal to the diameter of the coarse filter layer 112 , and there is no brush under the beating plate 1141 , which does not affect the cleaning of the coarse filter layer 112 .

[0109] It should be noted that the water mist sprayed by the atomizing nozzle 2341 can be adsorbed on the brushes of the upper cleaning plate 233 and the lower cleaning plate 235, which is convenient for cleaning the fine filter layer 111 and the coarse filter layer 112, and the upper cleaning plate 233 and the lower cleaning plate 235 are both detachable, which is convenient for cleaning both without affecting the normal use of the equipment.

[0110] Specifically, if Figures 8 to 14 As shown, a branch pipe 221 is fixed to the air inlet pipe 220, and a valve is fixed to the branch pipe 221. The valve is used to control the inlet and outlet air in the branch pipe 221. A boost pipe 2211 is fixed to the branch pipe 221. The free end of the boost pipe 2211 extends into the cleaning box 234, and a valve is fixed to the boost pipe 2211. When air is taken into the branch pipe 221, the valve of the boost pipe 2211 is opened, and vice versa. A valve is fixed to one end of the air inlet pipe 220 connected to the ventilation pipe 210, and when the valve is closed, it does not affect the normal inlet and outlet air of the air inlet pipe 220. When the upper cleaning plate 233 and the lower cleaning plate 235 enter the filter chamber 110, the valve on the air inlet pipe 220 is in a closed state.

[0111] A distribution pipe 2212 is fixed on the branch pipe 221 . The distribution pipe 2212 has two air outlet ends. One air outlet end of the distribution pipe 2212 extends into the first telescopic bag 2331 , and the other air outlet end of the distribution pipe 2212 extends into the second telescopic bag 2351 .

[0112] Specifically, if Figures 8 to 14 As shown, the brush of the upper cleaning plate 233 can extend into the mesh of the fine filter layer 111 , and the brush of the lower cleaning plate 235 can extend into the mesh of the coarse filter layer 112 .

[0113] It is easy to understand that the brushes on the upper cleaning plate 233 can further clean the mesh of the fine filter layer 111, and the brushes on the lower cleaning plate 235 can further clean the mesh of the coarse filter layer 112. Even when air enters the branch pipe 221, the expansion and movement of the first and second bellows bladders 2331 and 2351 will not affect the brushes from absorbing the cleaning liquid, and the upper and lower cleaning plates 233 and 235 can be cleaned.

[0114] On the basis of the above embodiment, air is supplied into the air intake pipe 220 through the air pump, so that air is supplied into the branch pipe 221, and the pressure in the cleaning box 234 is increased through the pressure boosting pipe 2211, so that the atomizing nozzle 2341 sprays atomized cleaning liquid, so that the brushes of the upper cleaning plate 233 and the brushes of the lower cleaning plate 235 adsorb fine water droplets with cleaning function, and the water droplets are not easy to fall off. After spraying, the air intake is stopped and the valve of the pressure boosting pipe 2211 is closed, and then the movable frame 232 is pushed to send the upper cleaning plate 233 and the lower cleaning plate 235 into the filter chamber 110;

[0115] When the upper cleaning plate 233 and the lower cleaning plate 235 reach the specified position, the air inlet pipe 220 is inflated and deflated by the air pump, so that the telescopic bag 1 2331 expands and contracts and drives the upper cleaning plate 233 to rise and fall repeatedly, and the brush on the upper cleaning plate 233 is used to clean the mesh of the fine filter layer 111. Similarly, when the telescopic bag 2 2351 expands and contracts, it can drive the lower cleaning plate 235 to rise and fall repeatedly to clean the mesh of the coarse filter layer 112. The water droplets of cleaning liquid adsorbed on the brush can deeply clean the impurities in the mesh and are not prone to water stains. It can achieve further deep cleaning of the fine filter layer 111 and the coarse filter layer 112, thereby improving the quality of gas detection.

[0116] In some embodiments of the present application, Figure 15 As shown, a handheld plate 150 is fixed to the side of the gas detector 100. The handheld plate 150 is a rectangular plate with a hollow interior and openings on both long sides, and a buffer capsule 151 is fixed to the inside thereof. A shunt tube 152 is fixed to the handheld plate 150, and a valve is fixed to the shunt tube 152.

[0117] One end of the shunt tube 152 is connected to the air inlet pipe 220 , and the other end of the shunt tube 152 extends into the buffer bag 151 .

[0118] In the above embodiment, the gas inspector passes his hand through the hand-held plate 150 and holds the gas detector 100, which can save effort. When it is necessary to free the fingers during the detection process and ensure that the gas detector 100 does not fall, the valve on the shunt tube 152 is opened to allow the gas to enter the buffer bag 151. As the buffer bag 151 continues to expand and squeeze the hand, the purpose of freeing the fingers is achieved, which facilitates the cooperation of both hands in operating operations and improves the convenience of use.

[0119] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
