Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to an atmospheric environment real-time monitoring device and method. Background Technology

[0002] Atmospheric environmental monitoring is the process of observing and analyzing the concentration of pollutants in the atmospheric environment and measuring their changes and environmental impacts. Atmospheric quality monitoring involves sampling and analyzing major pollutants in the atmosphere of a certain region. It is usually based on factors such as the size of a region, the distribution and intensity of air pollution sources, meteorological conditions, and topography, and involves regular monitoring of specified items.

[0003] An atmospheric environment monitoring device, such as the one disclosed in CN220603416U, includes a housing, a controller, and a detection mechanism. The controller is installed in the housing, and an air inlet pipe is installed on the top of the housing. The air inlet pipe is connected to an air pump, which is used to send external air into a sampling tube. The sampling tube is installed inside the housing, and the bottom of the sampling tube is connected to a discharge pipe that penetrates the housing. A water pump sends cleaning solution from a cleaning solution tank into the sampling tube through a flushing pipe. The cleaning solution flowing out of the flushing pipe flushes the inner wall of the sampling tube, carrying away dust and other impurities accumulated in the sampling tube that have entered with the external air, and sending them to a filter box for storage. The filter box can be extracted from the cleaning solution tank for convenient subsequent unified processing. This device can clean the sampling tube thoroughly, resulting in more accurate data on gas composition detection and a more accurate atmospheric environment assessment.

[0004] However, air quality sensors must be in full contact with air to make accurate measurements, and gas sensors require a certain amount of time to detect air quality. This time refers to the time required for the sensor to go from contacting the gas to outputting a stable reading (commonly represented by T90, i.e., reaching 90% of the final value). Typically, a relatively stable reading can be obtained in about 30 seconds. Existing detection methods that directly extract gas and allow it to flow through the gas sensor are suitable for detecting gas environments that remain constant. If the gas environment changes, because the gas does not make sufficient contact with the sensor or the contact time is too short, it is difficult to distinguish the changes in the gas environment, which will affect the detection effect and reduce the accuracy of the detection results. Summary of the Invention

[0005] The purpose of this invention is to provide an atmospheric environment real-time detection device and method to solve the problem that when the gas environment changes, it is difficult to distinguish the changing gas environment because the gas does not have sufficient contact with the sensor or the contact time is too short, which reduces the detection accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an atmospheric environment real-time detection device, comprising a base plate and a mounting box fixedly installed on the top of the base plate, wherein a door is hinged to one side of the front of the mounting box, an air inlet pipe is vertically fixedly connected to one side of the interior of the mounting box, and a detection sensor is fixedly installed on the inner bottom surface of the air inlet pipe;

[0007] Also includes:

[0008] A horizontal pipe is fixedly connected to one side of the bottom of the air intake pipe, a detection component is provided inside the upper part of the base plate, and a guide component is provided inside the lower part of the air intake pipe.

[0009] The detection assembly includes a drive motor slidably mounted inside the intake pipe. A reciprocating lead screw is fixedly connected to the output end of the drive motor. A rotating shaft is fixedly connected to the bottom of the reciprocating lead screw. A vertical rod is slidably mounted to the bottom end of the rotating shaft. A bevel gear is rotatably connected to the top side of the horizontal pipe.

[0010] Preferably, a screw is rotatably connected to one side of the air intake pipe, and a sleeve is threadedly connected to the outside of the screw. The sleeve is fixedly installed with a drive motor. A limit rod is fixedly connected to the top of the drive motor and is slidably connected to the air intake pipe. A chassis is fixedly connected to the bottom end of the rotating shaft. The vertical rod is symmetrically fixedly connected to the top of the bevel gear. A bevel gear ring is rotatably connected to the outside of the horizontal pipe. A fan blade is fixedly installed on the inside of the bevel gear ring. Two baffles are slidably installed laterally inside the air intake pipe.

[0011] By adopting the above technical solution, while extracting external gas, the intake pipe can be sealed at intervals, and the gas can be pushed to the position of the detection sensor by the guide plate. This enables segmented sampling and detection of gas, and ensures that the sampled gas is in full contact with the detection sensor. This allows for detection under changing gas environment conditions and improves the accuracy of the detection results.

[0012] Preferably, the vertical rod is slidably connected to the chassis, the bevel gear is meshed with the bevel gear ring, a horizontal rod is fixedly connected to the inside of the bevel gear ring, one end of the horizontal rod is fixedly connected to the fan blade, and the other end of the horizontal rod is fixedly connected to a blocking disc, with a fan-shaped groove formed on the outer side of the blocking disc.

[0013] By adopting the above technical solution, when the crossbar drives the fan blades and the blocking disc to rotate, the fan blades draw air from the intake pipe through the horizontal pipe.

[0014] Preferably, a fixed plate is also fixedly connected inside the horizontal tube. The fixed plate is located on the side of the blocking plate away from the horizontal bar. The fixed plate is in contact with the blocking plate. The fixed plate has through holes evenly and circumferentially opened inside. A sliding sleeve is threaded to the outer side of the reciprocating screw. A limit ring is fixedly connected to one side of the sliding sleeve. The limit ring is slidably connected to the sleeve.

[0015] By adopting the above technical solution, the rotation of the blocking disc will open the through hole at intervals, allowing the gas to be slowly discharged through the through hole.

[0016] Preferably, a vertical plate is fixedly connected to the other side of the sliding sleeve, and push plates are fixedly connected to the upper and lower sides of the outer side of the vertical plate. A trapezoidal block is fixedly connected to one side of the blocking plate, and a sleeve is fixedly connected to the side of the air intake pipe away from the blocking plate. The blocking plate and the inner wall of the sleeve are tightly fitted around the perimeter.

[0017] By adopting the above technical solution, the reciprocating screw rotates, causing the sliding sleeve to move up and down repeatedly. When the sliding sleeve rises, it drives the upper push plate to squeeze the lower inclined surface of the trapezoidal block. The movement of the trapezoidal block drives the blocking plate to move. The blocking plate drives the sliding strip and the fixed strip to move. The fixed strip compresses the spring until the blocking plate enters the sleeve box, at which point the blocking plate blocks the air intake of the air intake pipe.

[0018] Preferably, a slide bar is fixedly connected to the other side of the baffle plate, a fixing strip is fixedly connected to one end of the slide bar, a spring is fixedly connected to the side of the fixing strip away from the slide bar, the spring is fixedly connected to the inner wall of the sleeve, friction blocks are fixedly connected to both sides of the fixing strip, the friction blocks are in contact with the inner wall of the sleeve, and the height of the upper friction block is greater than the height of the lower friction block.

[0019] By adopting the above technical solution, since the height of the upper friction block is greater than that of the lower friction block, the upper fixing strip experiences greater sliding resistance. When the upper spring drives the fixing strip and the blocking plate to slide and reset, it takes longer, thus extending the blocking time of the blocking plate.

[0020] Preferably, the guide assembly includes a slide plate slidably mounted on the lower part of the intake pipe. One end of the slide plate is fixedly connected to a ramp, and a second spring is fixedly connected between the ramp and the outer wall of the intake pipe. The other end of the slide plate is fixedly connected to a compression plate. A longitudinal axis and two transverse axes are rotatably connected inside the lower part of the intake pipe. A guide plate is fixedly connected to the outer side of the longitudinal axis. A torsion spring is sleeved on the outer side of the longitudinal axis. The two ends of the torsion spring are fixedly connected to the intake pipe and the guide plate, respectively. A compression block is symmetrically fixedly connected to the middle of the outer side of the guide plate. An auxiliary plate is fixedly connected to the outer side of the transverse axes. A second torsion spring is sleeved on the outer side of the transverse axes. The two ends of the second torsion spring are fixedly connected to the auxiliary plate and the intake pipe, respectively.

[0021] By adopting the above technical solution, the lower push plate squeezes the inclined plate, the inclined plate compresses the second spring and drives the slide plate to move, the slide plate drives the squeeze plate to move, the squeeze plate squeezes the guide plate, the guide plate drives the longitudinal axis to rotate and acts on the first torsion spring, which can perform interval sealing of the air intake pipe and push the gas to the position of the detection sensor through the guide plate.

[0022] Preferably, a processing box is fixedly connected to the top of the air intake pipe, a filter plate is fixedly connected inside the processing box, a cover is fixedly installed on the top of the processing box, an air outlet pipe is fixedly connected to the side of the horizontal pipe away from the air intake pipe, a shut-off valve is fixedly installed on the outside of the air outlet pipe, and a control panel is fixedly installed on the outside of the mounting box.

[0023] By adopting the above technical solution, the fan blades draw air from the intake pipe through the horizontal pipe, the external gas enters the intake pipe through the treatment box, the filter plate pre-filters the gas, and the tested gas is discharged.

[0024] A detection method for an atmospheric environment real-time monitoring device includes the following steps:

[0025] Step 1: The operator starts the drive motor through the control panel. The fan blades draw air from the intake pipe through the horizontal pipe. External gas enters the intake pipe through the treatment box, and the filter plate pre-filters the gas.

[0026] Step 2: The drive motor drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the sliding sleeve to move up and down. When the sliding sleeve rises, it drives the upper push plate to press the lower inclined surface of the trapezoidal block. The movement of the trapezoidal block causes the blocking plate to move. The blocking plate blocks the air intake of the air intake pipe, and the lower push plate presses the inclined plate, causing the guide plate to drive the longitudinal axis to rotate and act on the torsion spring. This can block the air intake pipe at intervals and push the gas to the position of the detection sensor through the guide plate, realizing the segmented sampling and detection of the gas and keeping the sampled gas in full contact with the detection sensor.

[0027] Step 3: When the gas concentration being detected is low, the operator rotates the screw, which drives the sleeve to rise. The sleeve then drives the drive motor to rise. Because the height of the upper friction block is greater than that of the lower friction block, the upper fixing strip experiences greater sliding resistance. When the upper spring drives the fixing strip and the blocking plate to slide back to their original positions, it takes longer. This extends the blocking time of the blocking plate and simultaneously provides auxiliary guidance to the auxiliary plate, thereby further improving the detection efficiency.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up detection components and guiding components, and utilizing the cooperation of the air inlet pipe, detection sensor, push plate, baffle plate, and guide plate, the drive motor drives the fan blades to rotate and extract external gas while simultaneously sealing the air inlet pipe at intervals. The guide plate pushes the gas towards the detection sensor, thereby achieving segmented gas sampling and detection, and maintaining full contact between the sampled gas and the detection sensor. This adapts to detection under changing gas environment conditions and improves the accuracy of the detection results. Furthermore, when the gas concentration is low, adjustments can be made to extend the blocking time of the baffle plate and simultaneously provide auxiliary guidance from the auxiliary plate, further improving detection efficiency and expanding the applicability of the detection device. This makes it more convenient for practical air environment detection. The specific details are as follows:

[0029] 1. By setting up detection and guiding components, the operator starts the drive motor via the control panel. The drive motor drives the reciprocating screw and rotating shaft to rotate, the rotating shaft drives the chassis and vertical rod to rotate, the vertical rod drives the bevel gear and bevel gear ring to rotate, the bevel gear ring drives the horizontal rod to rotate, and the horizontal rod drives the fan blades and blocking disc to rotate. The fan blades draw air from the intake pipe through the horizontal pipe, and external gas enters the intake pipe through the processing box. The filter plate pre-filters the gas. The rotation of the blocking disc opens the through holes at intervals, allowing the gas to slowly exit through the through holes, which facilitates increasing the contact time. Initially, there is a gap between the blocking plate and the sleeve, which does not block the gas from entering, and the limiting ring slides on the outside of the sleeve. The rotation of the reciprocating screw causes the sliding sleeve to move up and down reciprocally. When the sliding sleeve rises, it will... The upper push plate presses the lower inclined surface of the trapezoidal block, the movement of the trapezoidal block drives the movement of the blocking plate, the blocking plate drives the movement of the sliding bar and the fixing bar, the fixing bar compresses the first spring until the blocking plate enters the sleeve, the blocking plate blocks the air intake of the air intake pipe, and the lower push plate presses the inclined plate, the inclined plate compresses the second spring and drives the sliding plate to move, the sliding plate drives the pressing plate to move, the pressing plate presses the guide plate, the guide plate drives the longitudinal axis to rotate, and acts on the first torsion spring, which can perform intermittent blocking of the air intake pipe, and push the gas to the position of the detection sensor through the guide plate, thereby realizing the segmented sampling and detection of gas, and keeping the sampled gas in full contact with the detection sensor, thus adapting to the detection under the condition of gas environment change, and improving the accuracy of the detection results;

[0030] 2. When the gas concentration being detected is low, the operator rotates the screw, which raises the sleeve, which in turn raises the drive motor. The drive motor then moves the limit rod, causing it to slide. At this time, the reciprocating screw, rotating shaft, and chassis rise. The chassis slides outside the vertical rod, maintaining the rotation of the drive bevel gear. The sliding sleeve rises with the drive motor, which in turn raises the vertical plate and push plate. The push plate acts on the upper trapezoidal block and sleeve. Because the height of the upper friction block is greater than that of the lower friction block, the upper fixing strip experiences greater sliding resistance. When the upper spring 1 moves the fixing strip and the blocking plate to slide and reset, it takes longer, thus extending the blocking time of the blocking plate. The lower push plate also rises, allowing the inclined plate to move a longer distance when it is subsequently squeezed. At this time, the rotation angle of the guide plate is larger. The guide plate squeezes the auxiliary plate through the squeezing block, causing the auxiliary plate to deflect. The auxiliary plate drives the horizontal shaft to rotate and acts on the torsion spring 2, simultaneously achieving auxiliary guidance of the auxiliary plate, thereby further improving the detection efficiency and expanding the applicability of the detection device.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1 - Figure 3 The present invention provides a technical solution: an atmospheric environment real-time detection device, including a base plate 1 and a mounting box 2 fixedly installed on the top of the base plate 1. A door 3 is hinged to one side of the front of the mounting box 2. An air inlet pipe 4 is vertically fixedly connected to one side of the interior of the mounting box 2. A detection sensor 14 is fixedly installed on the inner bottom surface of the air inlet pipe 4. The detection sensor 14 is a gas sensor.

[0047] A horizontal pipe 5 is fixedly connected to one side of the bottom of the air intake pipe 4, and a detection component 6 is provided inside the upper part of the base plate 1.

[0048] The top end of the air intake pipe 4 is fixedly connected to a processing box 8. A filter plate 9 is fixedly connected inside the processing box 8. A cover 10 is fixedly installed on the top of the processing box 8. The filter plate 9 is used to filter out large particulate impurities in the air. The cover 10 is detachably fixed to the processing box 8, which facilitates the subsequent removal and cleaning of the filter plate 9. An air outlet pipe 11 is fixedly connected to the side of the horizontal pipe 5 away from the air intake pipe 4. A shut-off valve 12 is fixedly installed on the outside of the air outlet pipe 11. A control panel 13 is fixedly installed on the outside of the mounting box 2.

[0049] like Figure 3 - Figure 11 As shown, the detection component 6 includes a drive motor 63 slidably installed inside the air intake pipe 4. The output end of the drive motor 63 is fixedly connected to a reciprocating lead screw 65. The bottom of the reciprocating lead screw 65 is fixedly connected to a rotating shaft 66. A vertical rod 69 is slidably installed at the bottom end of the rotating shaft 66. A bevel gear 68 is rotatably connected to one side of the top of the horizontal pipe 5.

[0050] A screw 61 is rotatably connected to one side of the inside of the intake pipe 4. A sleeve 62 is threadedly connected to the outside of the screw 61. The sleeve 62 is fixedly installed with the drive motor 63. A limit rod 64 is fixedly connected to the top of the drive motor 63. The limit rod 64 is slidably connected to the intake pipe 4. A chassis 67 is fixedly connected to the bottom end of the rotating shaft 66. The vertical rod 69 is symmetrically fixedly connected to the top of the bevel gear 68. A bevel gear ring 610 is rotatably connected to the outside of the horizontal pipe 5. A fan blade 612 is fixedly installed on the inside of the bevel gear ring 610. Two baffle plates 620 are slidably installed laterally inside the intake pipe 4.

[0051] The vertical rod 69 is slidably connected to the chassis 67, the bevel gear 68 is meshed with the bevel gear ring 610, a horizontal rod 611 is fixedly connected to the inside of the bevel gear ring 610, one end of the horizontal rod 611 is fixedly connected to the fan blade 612, and the other end of the horizontal rod 611 is fixedly connected to the blocking disc 613, and a fan-shaped groove is opened on the outer side of the blocking disc 613.

[0052] A fixed plate 614 is also fixedly connected inside the horizontal tube 5. The fixed plate 614 is located on the side of the blocking plate 613 away from the horizontal bar 611. The fixed plate 614 is in close contact with the blocking plate 613. The fixed plate 614 has through holes 615 evenly and circumferentially opened inside. As the blocking plate 613 rotates, the through holes 615 will be partially opened in sequence, which helps to slow down the gas outflow speed, help prolong the contact time and improve the detection effect.

[0053] The reciprocating lead screw 65 is threadedly connected to a sliding sleeve 616. A limiting ring 617 is fixedly connected to one side of the sliding sleeve 616. The limiting ring 617 is slidably connected to the sleeve 62. The limiting ring 617 limits the sliding sleeve 616 and keeps the sliding sleeve 616 moving up and down stably.

[0054] A vertical plate 618 is fixedly connected to the other side of the sliding sleeve 616. Push plates 619 are fixedly connected to the upper and lower sides of the outer side of the vertical plate 618. The length of the lower push plate 619 is greater than that of the upper push plate 619. A trapezoidal block 621 is fixedly connected to one side of the blocking plate 620. A sleeve 622 is fixedly connected to the side of the air intake pipe 4 away from the blocking plate 620. The blocking plate 620 and the inner wall of the sleeve 622 are tightly fitted together.

[0055] A slider 623 is fixedly connected to the other side of the baffle plate 620. A fixing strip 624 is fixedly connected to one end of the slider 623. A spring 625 is fixedly connected to the side of the fixing strip 624 away from the slider 623. The spring 625 is fixedly connected to the inner wall of the sleeve 622. Friction blocks 626 are fixedly connected to both sides of the fixing strip 624. The friction blocks 626 are in contact with the inner wall of the sleeve 622. The height of the upper friction block 626 is greater than that of the lower friction block 626. The larger the height of the friction block 626, the greater the friction force it experiences when sliding against the inner wall of the sleeve 622.

[0056] Example 1: As Figure 3 - Figure 12 As shown, the operator starts the drive motor 63 via the control panel 13. The drive motor 63 drives the reciprocating screw 65 and the rotating shaft 66 to rotate. The rotating shaft 66 drives the chassis 67 and the vertical rod 69 to rotate. The vertical rod 69 drives the bevel gear 68 and the bevel gear ring 610 to rotate. The bevel gear ring 610 drives the horizontal rod 611 to rotate. The horizontal rod 611 drives the fan blade 612 and the baffle plate 613 to rotate. The fan blade 612 draws air from the intake pipe 4 through the horizontal pipe 5. The external gas enters the intake pipe 4 through the processing box 8. The filter plate 9 pre-filters the gas. The rotation of the baffle plate 613 will open the through hole 615 at intervals, allowing the gas to slowly exit through the through hole 615, which facilitates the increase of contact time. There is a gap between the initial baffle plate 620 and the sleeve 622, which will not block the gas from entering.

[0057] The limiting ring 617 slides on the outside of the sleeve 62. The reciprocating screw 65 rotates, causing the sliding sleeve 616 to move up and down. When the sliding sleeve 616 rises, it drives the upper push plate 619 to press the lower inclined surface of the trapezoidal block 621. The movement of the trapezoidal block 621 drives the blocking plate 620 to move. The blocking plate 620 drives the sliding strip 623 and the fixing strip 624 to move. The fixing strip 624 compresses the spring 625 until the blocking plate 620 enters the sleeve 622, at which point the blocking plate 620 blocks the air intake of the air intake pipe 4.

[0058] The operator rotates screw 61, which drives sleeve 62 to rise. Sleeve 62 then drives drive motor 63 to rise, and drive motor 63 drives limit rod 64 to slide. At this time, reciprocating screw 65, rotating shaft 66, and chassis 67 rise. Chassis 67 slides outside vertical rod 69, still maintaining the rotation of drive bevel gear 68. Sliding sleeve 616 rises with drive motor 63, which drives vertical plate 618 and push plate 619 to rise. At this time, push plate 619 acts on upper trapezoidal block 621 and sleeve box 622. Since the height of upper friction block 626 is greater than that of lower friction block 626, the upper fixing bar 624 experiences greater sliding resistance. When upper spring 625 drives fixing bar 624 and blocking plate 620 to slide and reset, the time required is longer, thus extending the blocking time of blocking plate 620.

[0059] like Figure 3 and Figure 12 - Figure 13 As shown, a guide assembly 7 is provided inside the lower part of the air intake pipe 4. The guide assembly 7 includes a slide plate 71 slidably installed on the lower part of the air intake pipe 4. One end of the slide plate 71 is fixedly connected to a ramp 72. A spring 73 is fixedly connected between the ramp 72 and the outer wall of the air intake pipe 4. The other end of the slide plate 71 is fixedly connected to a compression plate 74. A longitudinal shaft 75 and two transverse shafts 79 are rotatably connected inside the lower part of the air intake pipe 4. A guide plate 76 is fixedly connected to the outer side of the longitudinal shaft 75.

[0060] A torsion spring 77 is sleeved on the outer side of the longitudinal shaft 75. The two ends of the torsion spring 77 are fixedly connected to the air intake pipe 4 and the guide plate 76, respectively. A compression block 78 is symmetrically fixedly connected to the middle of the outer side of the guide plate 76. An auxiliary plate 710 is fixedly connected to the outer side of the transverse shaft 79. A torsion spring 711 is sleeved on the outer side of the transverse shaft 79. The two ends of the torsion spring 711 are fixedly connected to the auxiliary plate 710 and the air intake pipe 4, respectively.

[0061] Example 2: Figure 9 - Figure 13As shown, the lower push plate 619 presses against the inclined plate 72, the inclined plate 72 compresses the second spring 73 and drives the slide plate 71 to move, the slide plate 71 drives the extrusion plate 74 to move, the extrusion plate 74 presses against the guide plate 76, the guide plate 76 drives the longitudinal shaft 75 to rotate and acts on the first torsion spring 77, which can perform interval sealing of the air inlet pipe 4, and push the gas to the position of the detection sensor 14 through the guide plate 76, thereby realizing segmented sampling and detection of gas, and keeping the sampled gas in full contact with the detection sensor 14, thus adapting to the detection under the condition of gas environment change and improving the accuracy of the detection results.

[0062] The height of the lower push plate 619 also rises with the drive motor 63, so that when the inclined plate 72 is squeezed later, the inclined plate 72 moves a longer distance. At this time, the rotation angle of the guide plate 76 is larger. The guide plate 76 squeezes the auxiliary plate 710 through the squeezing block 78, causing the auxiliary plate 710 to deflect. The auxiliary plate 710 drives the horizontal shaft 79 to rotate and acts on the second torsion spring 711, thus realizing the auxiliary guidance of the auxiliary plate 710, thereby further improving the detection efficiency and expanding the applicability of the detection device.

[0063] Working principle: When using this device, firstly, as... Figure 1 - Figure 13As shown, the operator starts the drive motor 63 via the control panel 13, causing the fan blades 612 to draw air from the intake pipe 4 through the horizontal pipe 5. External gas enters the intake pipe 4 through the processing box 8, where the filter plate 9 pre-filters the gas. The rotation of the baffle plate 613 intermittently opens the through hole 615, allowing the gas to slowly exit through the through hole 615. The rotation of the reciprocating screw 65 causes the sliding sleeve 616 to move up and down. When the sliding sleeve 616 rises, it drives the upper push plate 619 to press the lower inclined surface of the trapezoidal block 621. The movement of the trapezoidal block 621 drives the baffle plate 620 to move until the baffle plate 620 enters the housing 622. At this point, the baffle plate 620 blocks the air intake of the intake pipe 4, and the lower push plate 619 presses the inclined plate 72. The guide plate 76 drives the longitudinal shaft 75 to rotate, pushing the gas towards the position of the detection sensor 14 through the guide plate 76, thereby realizing segmented sampling and detection of the gas and maintaining the sampled gas in contact with the detection sensor. When the gas concentration is low, the operator rotates the screw 61, which drives the sleeve 62 to rise. The sleeve 62 then drives the drive motor 63 to rise, which in turn drives the vertical plate 618 and the push plate 619 to rise. At this time, the push plate 619 acts on the upper trapezoidal block 621 and the sleeve 622. Since the height of the upper friction block 626 is greater than that of the lower friction block 626, the blocking time of the blocking plate 620 is extended, and the height of the lower push plate 619 also rises. This results in the inclined plate 72 moving a longer distance when it is subsequently squeezed. At this time, the rotation angle of the guide plate 76 is larger. The guide plate 76 squeezes the auxiliary plate 710 through the squeezing block 78, causing the auxiliary plate 710 to deflect. The auxiliary plate 710 drives the horizontal shaft 79 to rotate, simultaneously achieving the auxiliary guidance of the auxiliary plate 710, thereby further improving the detection efficiency and expanding the applicability of the detection device.

4. A detection method for an atmospheric environment real-time monitoring device, characterized in that, The following are the steps for using the real-time atmospheric environment monitoring device as described in claim 3: Step 1: The operator starts the drive motor through the control panel. The fan blades draw air from the intake pipe through the horizontal pipe. External gas enters the intake pipe through the treatment box, and the filter plate pre-filters the gas. Step 2: The drive motor drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the sliding sleeve to move up and down. When the sliding sleeve rises, it drives the upper push plate to press the lower inclined surface of the trapezoidal block. The movement of the trapezoidal block causes the blocking plate to move. The blocking plate blocks the air intake of the air intake pipe, and the lower push plate presses the inclined plate, causing the guide plate to drive the longitudinal axis to rotate and act on the torsion spring. This can block the air intake pipe at intervals and push the gas to the position of the detection sensor through the guide plate, realizing the segmented sampling and detection of the gas and keeping the sampled gas in full contact with the detection sensor. Step 3: The operator rotates the screw, which drives the sleeve to rise. The sleeve then drives the drive motor to rise. Because the height of the upper friction block is greater than that of the lower friction block, the upper fixing strip experiences greater sliding resistance. When the upper spring drives the fixing strip and the blocking plate to slide and reset, it takes longer. This extends the blocking time of the blocking plate and simultaneously achieves the auxiliary guidance of the auxiliary plate, thereby improving the efficiency of the detection.
