Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, and in particular to an intelligent mobile environmental monitoring system for key mining areas. Background Technology

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

[0003] Because the concentration of solid particulate matter such as dust and coal slag in the mining environment is extremely high, pollutants quickly accumulate on the surface of the gas detector's filter. Moreover, the filters used in gas detectors are mostly needle filters, which are prone to clogging in dusty and humid environments. Once the filter is clogged, the suction power of the air pump will weaken, making it unable to effectively extract the sample gas from the test area. At the same time, impurities in the sampled gas will enter the detection instrument, affecting the normal operation of the sensor and leading to inaccurate detection results. Therefore, the filter needs to be replaced frequently, which is costly. If the filter is replaced during the detection process, it may lead to gas leakage or the infiltration of external pollutants, directly affecting the accuracy of the detection. Summary of the Invention

[0004] This application provides a mining intelligent mobile environmental monitoring system for key areas, which solves the problems in the prior art where frequent filter replacements are costly and can lead to gas leaks or external pollutants seeping in during the monitoring process, directly affecting the accuracy of the monitoring.

[0005] This application provides a mine-use intelligent mobile key area environmental monitoring system, including a gas detector, a filter chamber and an air inlet cylinder. The filter chamber is fixed with a fine filter layer and a coarse filter layer. The coarse filter layer is near the air inlet cylinder and also includes a cleaning component.

[0006] The cleaning assembly includes a vent pipe and an air inlet pipe;

[0007] The vent pipe is a ring-shaped tube and is fixed in the filter chamber near the gas detector. The vent pipe is located above the fine filter layer.

[0008] Multiple gas soft bags are uniformly fixed on the side of the ventilation tube near the fine filter layer, with one end of each gas soft bag extending into the ventilation tube.

[0009] Each of the gas soft bags has a striking block fixed on its empty end. One end of the air inlet pipe is connected to the air pump, and the other end of the air inlet pipe extends into the ventilation pipe.

[0010] The air inlet pipe fills and deflates the vent pipe, causing the gas soft bag to repeatedly expand and contract, which in turn drives the striking block to repeatedly beat the fine filter layer.

[0017] Furthermore, the fixing frame is a hollow cylinder and it is fixed inside the air intake cylinder by a rectangular plate, and the ribbon is a hollow elliptical cylindrical rubber strip that communicates with the inside of the fixing frame.

[0018] An air guide tube is fixed to the side of the fixed frame. One end of the air guide tube extends into the fixed frame, and the other end of the air guide tube is connected to the air inlet tube.

[0019] Furthermore, this also includes the cleaning department;

[0020] The cleaning unit includes a sealed chamber and a fixing plate;

[0021] The sealing chamber is fixed to the side of the filter chamber, the fixing plate is located inside the sealing chamber, and a movable frame is fixed on the side of the fixing plate away from the filter chamber.

[0022] The sealed chamber has a through hole on its side, and the spare end of the movable frame extends out of the sealed chamber through the through hole.

[0023] A cylindrical upper cleaning plate is fixed to the other side of the fixed plate near the filter chamber. The upper cleaning plate is located between the fine filter layer and the coarse filter layer. Brushes are fixed to the top and bottom of the upper cleaning plate. One brush is in contact with the surface of the fine filter layer and the other brush is in contact with the surface of the coarse filter layer.

[0024] The filter chamber has a reserved slot on the side near the sealing chamber. A partition is sealed and connected in the reserved slot, and the partition can be removed. After the partition is removed, the upper cleaning plate can be inserted into the filter chamber.

[0025] Furthermore, the partition is a semi-circular arc-shaped plate, and a protruding plate is fixed on its side. The protruding plate is located outside the filter chamber, and a groove is opened on the side of the filter chamber, in which a limiting plate is embedded.

[0026] The limiting plate is a semi-circular arc-shaped plate with a protrusion fixed on its side, and its end face abuts against the end face of the partition.

[0027] The filter chamber is threaded with a sealing cap near the air inlet, and the air inlet is fixed to the sealing cap.

[0028] Furthermore, a telescopic bladder is fixed on the fixed plate, and the upper cleaning plate is a hollow cylinder that is slidably connected to the fixed plate.

[0029] The telescopic bladder is used to push the upper cleaning plate to move, and the upper cleaning plate is located above the fine filter layer;

[0030] A cylindrical cleaning box is fixed in the middle of the fixed plate, and the cleaning box is located between the fine filter layer and the coarse filter layer;

[0031] The cleaning box contains cleaning fluid, and multiple atomizing nozzles are fixed at both ends of the cleaning box.

[0032] A telescopic bladder is fixed on the fixed plate away from the upper cleaning plate. A cylindrical lower cleaning plate is slidably connected to the fixed plate. A brush is fixed on the lower cleaning plate, and the lower cleaning plate is located below the coarse filter layer.

[0033] The diameter of the upper cleaning plate is equal to the diameter of the fine filter layer, and the diameter of the lower cleaning plate is equal to the diameter of the coarse filter layer.

[0034] Furthermore, a branch pipe is fixed to the intake pipe, a valve is fixed to the branch pipe, and a booster pipe is fixed to the branch pipe;

[0035] The unused end of the booster pipe extends into the cleaning box, and a valve is fixed on the booster pipe. A valve is also fixed at the end of the air inlet pipe that connects to the vent pipe.

[0036] A distribution pipe is fixed on the branch pipe. The distribution pipe has two air outlets. One air outlet of the distribution pipe extends into the first telescopic bladder, and the other air outlet of the distribution pipe extends into the second telescopic bladder.

[0037] Furthermore, the brush of the upper cleaning plate can extend into the mesh of the fine filter layer, and the brush of the lower cleaning plate can extend into the mesh of the coarse filter layer.

[0038] Furthermore, a handheld plate is fixed to the side of the gas detector. The handheld plate is a rectangular plate with a hollow interior and openings on both sides of its long side, and a buffer bladder is fixed to its inner side. A diversion tube is fixed to the handheld plate, and a valve is fixed to the diversion tube.

[0039] One end of the diverter tube is connected to the intake tube, and the other end of the diverter tube extends into the buffer bladder.

[0040] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0041] The cleaning components, through the air inlet pipe, inflate and deflate the air duct, causing the gas bladder to repeatedly expand and contract, which in turn drives the striking block to repeatedly beat the fine filter layer. This repeated beating of the fine filter layer dislodges the trapped dust, reducing clogging and eliminating the need for frequent filter replacements. The system can clean the filter chamber during gas detection, ensuring the accuracy of gas detection. Attached Figure Description

[0064] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

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

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

[0067] like Figures 1 to 4 As shown, this application proposes a mine-use intelligent mobile key area environmental monitoring system, 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 at the bottom of the gas detector 100, and an air inlet 120 is fixed at the bottom of the filter chamber 110. The gas in the detection area enters the filter chamber 110 from the air inlet 120, and enters the gas detector 100 after being filtered by the filter chamber 110. A fine filter layer 111 is fixed in the filter chamber 110 near the gas detector 100, and a coarse filter layer 112 is fixed in the filter chamber 110 near the air inlet 120. 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 inlet pipe 220;

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

[0070] Multiple gas soft bags 211 are uniformly and fixed on the side of the ventilation tube 210 near the fine filter layer 111. One end of the gas soft bag 211 extends into the ventilation tube 210, and the connection between the gas soft bag 211 and the ventilation tube 210 is airtight and fixed.

[0071] Each of the gas soft bags 211 has a striking block 212 fixed on its empty end. One end of the air inlet pipe 220 is connected to the air pump, which is fixed on 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 intake pipe 220 inflates and deflates the air vent pipe 210, causing the gas soft bag 211 to repeatedly expand and contract, which in turn drives the striking block 212 to repeatedly beat 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, while the coarse filter layer 112 can intercept dust particles of 0.5mm to 1mm. The fine filter layer 111 is more prone to clogging than the coarse filter layer 112. By repeatedly striking the fine filter layer 111 with the striking block 212, the intercepted dust can be knocked off, and the dust can pass through the coarse filter layer 112 and fall down, reducing clogging.

[0074] It also includes wireless transceivers, displays, and network switches;

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

[0076] It is worth noting that the gas detector 100 has a storage function. When no wireless transceiver is installed at the inspection point, the gas inspector can save the detection data manually. After going up the well, the saved detection data can be synchronized to the central station.

[0077] The gas detector 100 has a miniature air pump 130 fixed inside. An air extraction pipe 131 is fixed to the air inlet end of the miniature air pump 130, and an air delivery pipe 132 is fixed to the air outlet end of the miniature air pump 130. A detection module 140 is fixed inside the gas detector 100. The detection module 140 is used to detect the concentration of the gas. The unused end of the air delivery pipe 132 is connected to the detection module 140. An air outlet pipe 133 is fixed on the detection module 140, and the unused end of the air outlet pipe 133 extends out of the gas detector 100.

[0078] It is easy to understand that by using a micro air pump 130 to draw air from the suction pipe 131, the gas in the detection area enters the filter chamber 110 from the air inlet 120. After filtration, the gas enters the air delivery pipe 132 through the suction pipe 131, and is then sent into the detection module 140 through the air delivery pipe 132. Finally, the gas is discharged from the exhaust pipe 133. The detection module 140 can detect methane, carbon monoxide, oxygen, hydrogen sulfide, ambient temperature, etc.

[0079] Specifically, such as Figures 5 to 7 As shown, the fine filter layer 111 has a through groove, and a soft mesh 1111 is fixed in the through groove. The mesh diameter of the soft mesh 1111 is the same as that of the fine filter layer 111. That is to say, the soft mesh 1111 can also intercept dust particles of 0.2μm to 0.35μm. Multiple collision blocks 1112 are fixed on the soft mesh 1111 near the coarse filter layer 112.

[0080] Multiple flexible plates 114 are fixed inside the filter chamber 110. The flexible plates 114 are located between the fine filter layer 111 and the coarse filter layer 112. A hammer plate 1141 is fixed on the unused end of each flexible plate 114. The hammer plate 1141 is located below the collision block 1112.

[0081] The striking block 212 is located above the soft mesh 1111. The striking block 212 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 hammer plate 1141, and the hammer plate 1141 can hammer the coarse filter layer 112.

[0082] It should be noted that the lower part of the striking block 212 penetrates into the soft mesh 1111, causing the soft mesh 1111 to deform and indent downwards. At this time, the upper part of the striking block 212 can still collide with the fine filter layer 111. Moreover, the soft plate 114 has good elasticity. When the hammer plate 1141 hammers the coarse filter layer 112 downwards, the gas soft bag 211 contracts and drives the striking block 212 to move upwards. Because the soft plate 114 has high elastic strength, the impact generated by the hammer plate 1141 can react on the impact block 1112. The gap created by the upward movement of the striking block 212 is used to strike the fine filter layer 111 and the soft mesh 1111 again, further improving the cleaning efficiency.

[0083] Specifically, such as Figures 5 to 7 As shown, a fixing frame 121 is fixed inside the air inlet cylinder 120 near the coarse filter layer 112. The fixing frame 121 occupies little space and does not affect the entry of gas. A ribbon 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 tested 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 contacting the ribbon 122. This not only makes the dust particles in the gas evenly dispersed and avoids excessive blockage in the area, but also increases the flow speed of the airflow and improves the efficiency of the test.

[0085] Specifically, such as Figures 5 to 7 As shown, the fixing frame 121 is a hollow cylinder and it is fixed inside the air inlet cylinder 120 by a rectangular plate. The ribbon 122 is a hollow elliptical cylindrical rubber strip. That is to say, gas can enter the space of the cylindrical structure of the ribbon 122. The ribbon 122 is connected to the inside of the fixing frame 121. In other words, when air is introduced into the fixing frame 121, the gas can enter the ribbon 122.

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

[0087] It is easy to understand that when the air inlet pipe 220 is repeatedly filled and deflated, the air duct 1211 is also repeatedly filled and deflated, thereby causing the ribbon 122 to be repeatedly filled and deflated. When air enters the ribbon 122, the ribbon 122 will expand and compress the gas in its space to be discharged. When air is drawn out of the ribbon 122, a negative pressure will be generated in its cylindrical space, which will draw the gas in the air inlet pipe 120 into the cylindrical space. This repeated process can more quickly disturb the flow rate of the airflow. Moreover, the swing caused by the expansion and contraction of the ribbon 122 can also disturb the flow state of the surrounding airflow, further increasing the flow rate of the airflow and dispersing dust and impurities in the airflow.

[0088] In the above embodiments, gas inspectors carry gas detectors 100 to patrol underground mines. When the gas inspectors arrive at the patrol point, they use the gas detectors 100 to transmit the detected environmental data, such as methane, carbon monoxide, oxygen, hydrogen sulfide, and ambient temperature, to the surface central station via a wireless transceiver and switch. The various detection data are then displayed on the screen. This can improve the standardization and informatization of coal mines, and transmit the data detected by gas inspectors to underground workers in a timely and effective manner, effectively reducing or avoiding the occurrence of safety accidents and providing a guarantee for safe production in coal mines.

[0089] During gas detection, the gas inspector holds the gas detector 100 with the air inlet of the air inlet cylinder 120 facing the ground. The micro air pump 130 draws gas from the detection area, allowing the detection gas to enter the filter chamber 110 from the air inlet 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 ribbon 122 to increase the airflow velocity. When air enters the air pipe 210, the gas soft bag 211 inflates and expands, causing the striking block 212 to descend rapidly and strike the fine filter layer 111. At the same time, it causes the hammer 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 gas detection, reduce blockage, and thus improve the quality of gas detection.

[0090] In some embodiments of this application, such as Figures 5 to 7 As shown, it also includes a cleaning unit 230;

[0091] The cleaning unit 230 includes a sealed 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 inside the sealing chamber 231, and the movable frame 232 is fixed on 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 unused 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 on the other side of the fixed plate 2321 near the filter chamber 110. The upper cleaning plate 233 is located between the fine filter layer 111 and the coarse filter layer 112. Brushes are fixed on the top and bottom of the upper cleaning plate 233. One brush is in contact with the surface of the fine filter layer 111 and the other brush is in contact with the surface of the coarse filter layer 112.

[0095] The filter chamber 110 has a reserved slot on the side near the sealing chamber 231. A partition 116 is sealed and connected in the reserved slot. The partition 116 can be removed. After the partition 116 is removed, the upper cleaning plate 233 can be inserted into the filter chamber 110.

[0096] It is worth noting that when further cleaning the fine filter layer 111 and the coarse filter layer 112, the partition plate 116 can be removed, and the moving frame 232 can be pushed into the filter chamber 110. By moving the moving frame 232 back and forth, the fine filter layer 111 and the coarse filter layer 112 can be further cleaned with a brush. This eliminates the 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, such as Figures 8 to 11As shown, the partition 116 is a semi-circular arc-shaped plate, and a protruding plate is fixed on its side. The protruding plate is located outside the filter chamber 110. A groove is opened on the side of the filter chamber 110, and a limiting plate 115 is embedded in the groove.

[0098] The limiting plate 115 is a semi-circular arc plate with a protrusion fixed on its side. The protrusion is used to increase the contact force with the hand, making it easier to remove the limiting plate 115. Its end face abuts against the end face of the partition plate 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 together, and the sealing cover 113 can be removed by rotating it.

[0100] It should be noted that the limiting plate 115 is used to limit and fix the partition 116 to ensure that the partition 116 does not shift. When it is necessary to rotate the partition 116 to clean the fine filter layer 111 and the coarse filter layer 112, first remove the limiting plate 115, and then rotate the convex plate to rotate 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 off and the limiting plate 115 is removed. Then, the pull plate is pushed to rotate the partition 116 outward. Then, the moving frame 232 is pushed to push the upper cleaning plate 233 into the filter chamber 110. 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 cleaned impurities are discharged outward. It is not necessary 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 this application, such as Figures 12 to 14 As shown, a telescopic bladder 2331 is fixed on the fixed plate 2321. The upper cleaning plate 233 is a hollow cylinder and is slidably connected to the fixed plate 2321. The telescopic bladder 2331 is located above the upper cleaning plate 233. The upper cleaning plate 233 is detachably connected to the fixed plate 2321 by a buckle. That is to say, the upper cleaning plate 233 and the fixed plate 2321 can be disassembled by a buckle.

[0103] A guide plate 2322 is fixed on the fixed plate 2321. A sliding groove is opened in the sealed chamber 231. The guide plate 2322 extends into the sliding groove. In this way, when the moving frame 232 pushes the fixed plate 2321, the guide plate 2322 can move horizontally in the sliding groove, and the guide plate 2322 supports and guides the fixed plate 2321.

[0104] The telescopic bladder 2331 is used to push the upper cleaning plate 233 to move, and 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 sealing chamber 231 can be opened. The cleaning box 234 has a liquid injection port, which makes it easy to add cleaning liquid to the cleaning box 234 in a timely manner.

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

[0107] A second telescopic bladder 2351 is fixed on the fixed plate 2321 at a distance away from the upper cleaning plate 233. A cylindrical lower cleaning plate 235 is slidably connected to the fixed plate 2321. The second telescopic bladder 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 detached by a buckle. A brush is fixed on 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, and the diameter of the lower cleaning plate 235 is equal to the diameter of the coarse filter layer 112. There are no brushes under the hammer plate 1141, so it 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 onto the brushes of the upper cleaning plate 233 and the lower cleaning plate 235, which facilitates the cleaning of the fine filter layer 111 and the coarse filter layer 112. Furthermore, both the upper cleaning plate 233 and the lower cleaning plate 235 are detachable, making it easy to clean them without affecting the normal use of the equipment.

[0110] Specifically, such as Figures 8 to 14 As shown, a branch pipe 221 is fixed on the air intake pipe 220, and a valve is fixed on the branch pipe 221. The valve is used to control the air intake and exhaust in the branch pipe 221. A booster pipe 2211 is fixed on the branch pipe 221. The unused end of the booster pipe 2211 extends into the cleaning box 234, and a valve is fixed on the booster pipe 2211. When air enters the branch pipe 221, the valve of the booster pipe 2211 opens, and vice versa. A valve is fixed at one end of the air intake pipe 220 connected to the ventilation pipe 210, and the valve does not affect the normal air intake and exhaust of the air intake pipe 220 when it is closed. When the upper cleaning plate 233 and the lower cleaning plate 235 enter the filter chamber 110, the valve on the air intake pipe 220 is in the closed state.

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

[0112] Specifically, such as 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 brush of the upper cleaning plate 233 can further clean the mesh of the fine filter layer 111, and the brush of the lower cleaning plate 235 can further clean the mesh of the coarse filter layer 112. Even when air is introduced into the branch pipe 221, the expansion and movement of the first expansion bladder 2331 and the second expansion bladder 2351 will not affect the brush adsorption of cleaning liquid, and the upper cleaning plate 233 and the lower cleaning plate 235.

[0114] Based on the above embodiment, air is introduced into the air inlet pipe 220 by an air pump, and air is introduced into the branch pipe 221. The pressure is increased in the cleaning box 234 by the pressurizing pipe 2211, so that the atomizing nozzle 2341 sprays atomized cleaning liquid. The brushes of the upper cleaning plate 233 and the lower cleaning plate 235 are adsorbed with 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 pressurizing pipe 2211 is closed. Then the moving 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 designated position, the air pump inflates and deflates the air inlet pipe 220, causing the first telescopic bladder 2331 to expand and contract, and driving the upper cleaning plate 233 to rise and fall repeatedly. The brush on the upper cleaning plate 233 cleans the mesh of the fine filter layer 111. Similarly, when the second telescopic bladder 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. This can achieve further deep cleaning of the fine filter layer 111 and the coarse filter layer 112, and improve the gas detection quality.

[0116] In some embodiments of this application, such as 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 sides of its long side. A buffer bladder 151 is fixed to its inner side. A diversion tube 152 is fixed to the handheld plate 150, and a valve is fixed to the diversion tube 152.

[0117] One end of the diverter pipe 152 is connected to the intake pipe 220, and the other end of the diverter pipe 152 extends into the buffer bladder 151.

[0118] In the above embodiment, the gas inspector holds the gas detector 100 after passing his hand through the handheld plate 150, which can save effort. During the detection process, when it is necessary to free the fingers and ensure that the gas detector 100 will not fall, the valve on the diversion tube 152 is opened to allow the gas to enter the buffer bladder 151. As the buffer bladder 151 expands and squeezes the hand, the purpose of freeing the fingers is achieved, which facilitates the operation of both hands and improves the convenience of use.

[0119] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. 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.
