[0013] An arc-shaped slide groove is provided on the circumferential side of the through hole of the fixed plate, and a driving rod is slidably engaged on the inner arc surface of the arc-shaped slide groove, and an adjustment plate is fixedly installed on the bottom end of the driving rod.

The upper surface of the spin-on plate is movably connected to the fixed plate through a rotating shaft. There are four spin-on plates, which are evenly distributed on the fixed plate in the form of a ring array.

[0014] A main rod is fixedly installed on the upper surface of the supporting universal joint, a support platform is fixedly installed on the upper surface of the main rod, a wind direction detector is fixedly installed on one side of the upper surface of the support platform, and a wind speed detector is fixedly installed on the other side of the support platform. A lower support platform is provided on the lower surface of the main rod, and air analyzers are fixedly installed on both sides of the upper surface of the lower support platform. A central processing unit integration box is fixedly installed on one side of the adjustment component.

[0015] A method for using an air pollution detection device, the method using the above-mentioned air pollution detection device, comprising the following steps: A1. The wind direction is detected by the wind speed detector, and the detected data is then transmitted to the central processing unit integration box. The central processing unit integration box controls the operation of the first motor, which drives the expansion assembly to operate and adjusts the direction of the wind direction detector to rotate it to the windward side. The external wind enters the interior of the air analyzer through the rotating rotary plate, and the air is monitored by the air analyzer. A2. The air flow is directed to the fixed plate on the mounting frame, and the impurities on the air after passing through the air analyzer are analyzed to obtain the quantity and type of impurities. When the air pollution is more serious and there are more impurities in the air, the first motor drives the gear ring to rotate. Under the support of the rotating force, the adjustment plates connected between the two gear rings drive the driving rods in the arc-shaped slide grooves to rotate accordingly. The rotating driving rods drive the rotating plates to rotate around the axis, so that the holes between the multiple rotating plates are reduced. After the holes are reduced, the air flow is concentrated in the central area of the air analyzer, which is convenient for centralized observation and analysis of impurities in the atmosphere. When the air pollution is more serious and there are more impurities in the air, the adjustment plate is rotated to enlarge the holes enclosed by the multiple rotating plates, and the diameter of the wiring harness for the guided air is increased. The impurities are more dispersedly arranged on the air analyzer, and there is not much overlap between the impurities. A3. Meanwhile, the rotation of the output shaft of the second motor can drive the rotation of the driving gear. The driving gear is meshed and connected with the annular teeth, so that the rotation of the driving gear can drive the U-shaped clamping block to move in a circular motion outside the annular teeth. The movement of the U-shaped clamping block drives the adjustment to slide outside the limit ring, causing the air analyzer on the main rod at its top to rotate until it reaches the windward side. When the staff rotates the platform knob, the translation gear rotates and meshes with the turntable translation rack. The reaction force from the translation rack pushes the installation platform to move in the opposite direction, realizing the translation movement of the installation platform relative to the carrier. At the same time, the installation frame at the rear end is movably clamped in the two moving grooves through the locking parts at the rear end of the carrier. During the translation movement relative to the carrier, the two locking parts at the rear end move vertically on the moving grooves on both sides of the installation frame. A4. When it is necessary to change the location for atmospheric detection, there is an elastic part on the adjusting part that moves along with the adjusting part. The inner diameter of the conical groove in the connecting kit corresponding to the movement track of the elastic part gradually decreases along one direction, so that the elastic part gathers towards the center to press the probe when moving along with the adjusting part, or the elastic part loosens the protruding end due to the deformation of restoring from the gathered state to the initial state. One end of the conical groove extending into the adjusting part is provided with a threaded part, and the inner thread is correspondingly provided on the peripheral wall of the connecting kit. The adjusting part rotates in the connecting kit, and the cooperation between the inner thread and the threaded part converts the circumferential displacement of the rotation of the adjusting part into a linear displacement along the axial direction, thereby changing the depth of the adjusting part in the connecting kit. At the same time, the rotating rod can also be rotated in the reverse direction to make the arc grooves on both sides, so that the protruding ends on both sides are disengaged from the clamping with the rotating rod, thus completing the quick disassembly.

[0016] The beneficial effects of the present invention are as follows: 1. The disassembly component can be used for comprehensive inspection and maintenance. For example, when the equipment fails or the measurement is inaccurate, after disassembly, the problem can be diagnosed more deeply, and targeted repairs can be carried out. This helps to improve the reliability and accuracy of the equipment, ensuring that the subsequent pollution detection data is more reliable. When large-scale infrastructure construction, building construction or site renovation is carried out in certain areas, the pollution detection equipment may hinder the construction process. At this time, temporarily disassembling the equipment can facilitate the construction and avoid damage to the equipment. After the construction is completed, the equipment can be reinstalled to resume pollution monitoring.

[0017] 2. By relying on the adjustment component, the sampling port of the detection equipment can be placed in a more appropriate position to obtain more representative air samples. For example, for pollution sources with different heights of emissions, adjusting the height of the air analyzer can better capture the distribution of pollutants. As the wind direction changes, the diffusion direction of pollutants also changes. By adjusting the angle of the adjustment component, it can always be aligned with the main pollution diffusion direction, improving the detection sensitivity to pollutants.

[0018] 3. Drive the rotating matching plate to rotate around the axis through the rotating drive rod, so that the holes between multiple rotating matching plates are reduced. After reduction, the air flow is concentrated in the central area of the air analyzer, which is convenient for centralized observation and analysis of impurities in the atmosphere; when the air pollution is relatively serious and there are many impurities in the air, rotate the adjusting plate to make the holes enclosed by multiple rotating matching plates larger, and the diameter of the air flow bundle for guiding air becomes larger. The impurities are more dispersed on the air analyzer, and there will not be too much overlap between the impurities, which is convenient for the detector to observe and analyze the quantity and type of impurities, making the detection more accurate.

Detailed implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, the embodiment of the present invention includes a support mounting base 1. A stabilizing block 2 is fixedly installed in the middle of the upper surface of the support mounting base 1. A rotating rod 3 is threadedly connected to the upper surface of the stabilizing block 2. A disassembly component 4 is provided at the top of the outer arc surface of the rotating rod 3. The disassembly component 4 includes an adjusting piece 401 penetrating and connected to the top of the surface of the rotating rod 3. The middle of the lower surface of the adjusting piece 401 is fixedly installed with a threaded piece 402. Elastic pieces 403 are provided on both sides of the lower surface of the threaded piece 402. The top end of the adjusting piece 401 is movably connected with a connecting kit 404 through the threaded piece 402. A conical groove 405 is provided in the middle of the inner arc surface of the connecting kit 404. The inner arc surface of the conical groove 405 is movably clamped with the elastic piece 403. The protruding ends of 406 are provided at both bottom ends of the elastic piece 403. A spring 407 is fixedly installed on the lower surface of the threaded piece 402. One end of the spring 407 is movably sleeved in the two elastic pieces 403. Arc grooves 408 are provided on both sides of the outer arc surface of the rotating rod 3 penetrating through the connecting kit 404. The inner arc surfaces of the two arc grooves 408 are movably clamped with the two protruding ends 406. The top end of the rotating rod 3 is fixedly provided with an adjusting component 5.

[0024] When it is necessary to change the location for atmospheric detection, an elastic member 403 is provided on the adjusting member 401. As the adjusting member 401 moves, the inner diameter of the conical groove 405 on the connecting kit 404 gradually decreases along one direction corresponding to the moving track of the elastic member 403, so that the elastic member 403 gathers towards the center to press the probe when moving with the adjusting member 401, or the elastic member 403 deforms from the gathered state to the initial state to release the protruding end 406. A threaded member 402 is provided at one end of the conical groove 405 into which the adjusting member 401 extends, and an internal thread is correspondingly provided on the peripheral wall of the connecting kit 404. The adjusting member 401 rotates within the connecting kit 404, and the cooperation between the internal thread and the threaded member 402 converts the circumferential displacement of the rotation of the adjusting member 401 into a linear displacement along the axial direction, thereby changing the depth of the adjusting member 401 within the connecting kit 404. At the same time, the rotating rod 3 can also be rotated in the reverse direction to make the arc-shaped grooves 408 on both sides, so that the protruding ends 406 on both sides are disengaged from the clamping connection with the rotating rod 3, thus completing the quick disassembly.

[0025] Secondly, the disassembly component 4 can be used to conduct a comprehensive inspection and repair on it. For example, when the equipment fails or the measurement is inaccurate, after disassembly, the problem can be diagnosed more deeply, and targeted repairs can be carried out. This helps to improve the reliability and accuracy of the equipment, ensuring that the subsequent pollution detection data is more reliable. And when large-scale infrastructure construction, building construction or site renovation is carried out in certain areas, the pollution detection equipment may hinder the construction process. At this time, temporarily disassembling the equipment can facilitate the construction and avoid damage to the equipment. After the construction is completed, the equipment can be reinstalled to resume pollution monitoring.

[0026] Embodiment 2: As Figure 3 、 Figure 6 、 Figure 7 and Figure 10As shown in the figure, the adjusting assembly 5 includes a mounting platform 501 fixedly installed at the top end of the rotating rod 3. A protruding portion 502 is provided in the middle of the lower surface of the mounting platform 501.

A limiting ring 507 is fixedly installed on the outer arc surface of the annular connecting plate 506. A U-shaped clamping block 508 is movably clamped on the outer arc surface of the limiting ring 507. A connecting arm 509 is fixedly installed on one side of the outer arc surface of the U-shaped clamping block 508. An annular gear 510 is fixedly installed on the circumferential side of the upper surface of the mounting platform 501. An L-shaped mounting plate 511 is fixedly installed on one side of the upper surface of the annular gear 510. A driving gear 512 is rotatably connected to the upper surface of the L-shaped mounting plate 511 through a rotating shaft. The serrated portion on the outer arc surface of the driving gear 512 is meshed and connected with the annular gear 510. Platform knobs 513 are fixedly installed on both sides of the protruding portion 502 on the lower surface of the U-shaped clamping block 508. A translation gear 514 is fixedly installed on one side of the outer arc surface of the platform knob 513.

One end of the locking member 516 is movably clamped into the moving groove 519.

[0027] Driving the rotation of the output shaft of the second motor can drive the rotation of the driving gear 512. The driving gear 512 is meshed and connected with the annular gear 510, so that the rotation of the driving gear 512 can drive the U-shaped clamping block 508 to perform a circular motion outside the annular gear 510. The movement of the U-shaped clamping block 508 drives the adjustment to slide outside the limiting ring 507, so that the air analyzer 10 on the main rod 7 at its top rotates until it reaches the windward side. When the staff rotates the platform knob 513, the translation gear 514 rotates and meshes with the turntable translation rack 517. The reaction force from the translation rack 517 reversely pushes the mounting platform 501 to move, realizing the translation movement of the mounting platform 501 relative to the bearing frame 515. At the same time, the mounting frame 518 at the rear end is movably clamped in the two moving grooves 519 through the locking members 516 at the rear end of the bearing frame 515. When performing the translation movement relative to the bearing frame 515, the two locking members 516 at the rear end move vertically on the moving grooves 519 on both sides of the mounting frame 518.

[0028] By relying on the adjustment component 5, the sampling port of the detection device can be placed in a more appropriate position to obtain a more representative air sample. For example, for pollution sources with different emission heights, adjusting the height of the air analyzer 10 can better capture the distribution of pollutants. As the wind direction changes, the diffusion direction of pollutants also changes. By adjusting the angle of the adjustment component 5, it can always be aligned with the main pollution diffusion direction, improving the detection sensitivity to pollutants.

[0029] Embodiment 3: As Figure 2 , Figure 4 , Figure 5 and Figure 10 shown, the upper surface of the mounting frame 518 is provided with an extension surface, and through holes are opened on the upper surface of the extension surface. The lower surface of the mounting frame 518 is fixedly installed with an expansion component 6 by bolts. The expansion component 6 includes a fixing plate 601 fixedly installed on the lower surface of the mounting frame 518. A through hole is opened in the middle of the upper surface of the fixing plate 601. The through hole on the upper surface of the fixing plate 601 corresponds to the through hole on the extension surface. An arc-shaped sliding groove 602 is opened on the circumference of the through hole of the fixing plate 601. A driving rod 603 is slidably clamped on the inner arc surface of the arc-shaped sliding groove 602. The bottom end of the driving rod 603 is fixedly installed with an adjusting plate 604. Both sides of the adjusting plate 604 are movably connected with a toothed ring 605 through a rotating shaft. The inner arc surface serrated part of the toothed ring 605 is meshed and connected with a rotating and matching plate 606. The upper surface of the rotating and matching plate 606 is movably connected to the fixing plate 601 through a rotating shaft. The number of the rotating and matching plates 606 is four and they are evenly distributed on the fixing plate 601 in a circular array form. The upper surface of the support universal joint 504 is fixedly installed with a main rod 7. The upper surface of the main rod 7 is fixedly installed with a support platform. On one side of the upper surface of the support platform, a wind direction detector 8 is fixedly installed. On the other side of the support platform, a wind speed detector 9 is fixedly installed. A lower support platform is provided on the lower surface of the main rod 7. Air analyzers 10 are fixedly installed on both sides of the upper surface of the lower support platform. A central processor integration box 11 is fixedly installed on one side of the adjustment component 5.

[0030] The atmosphere is guided into the fixed plate 601 on the mounting frame 518, and the impurities on the air after passing through the air analyzer 10 are analyzed to obtain the quantity and type of impurities. When the air pollution is more serious and there are more impurities in the air, the first motor drives the gear ring 605 to rotate. Under the support of the rotational force, the adjustment plates 604 connected between the gear rings 605 drive the drive rod 603 in the arc-shaped slide groove 602 to rotate accordingly. The rotating drive rod 603 drives the spin-on plate 606 to rotate around the axis, so that the holes between the multiple spin-on plates 606 are reduced. After the holes are reduced, the air flow is concentrated in the central area of the air analyzer 10, which is convenient for centralized observation and analysis of impurities in the atmosphere. When the air pollution is more serious and there are more impurities in the air, the adjustment plate 604 is rotated to enlarge the holes enclosed by the multiple spin-on plates 606, and the diameter of the wiring harness for guiding the air is enlarged, so that the impurities are more dispersedly distributed on the air analyzer 10.

[0031] When the air pollution is not serious and there are fewer impurities in the air, the rotating drive rod 603 drives the spin-on plate 606 to rotate around the axis, so that the holes between the multiple spin-on plates 606 are reduced. After the holes are reduced, the air flow is concentrated in the central area of the air analyzer 10, which is convenient for centralized observation and analysis of impurities in the atmosphere; when the air pollution is more serious and there are more impurities in the air, the adjustment plate 604 is rotated to enlarge the holes enclosed by the multiple spin-on plates 606, and the diameter of the wire bundle for draining air is increased. The impurities are more dispersedly distributed on the air analyzer 10, and there will not be too much overlap between the impurities, which is convenient for the detector to observe and analyze the quantity and type of impurities, making the detection more accurate.

[0032] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

10. A method for using an air pollution detection device, the method using an air pollution detection device as described in claims 1 to 9, characterized in that: Including the following steps: A1. Detect the direction of the wind through the wind speed detector (9), and then transmit the detected data to the central processor integration box (11). Control the first motor to work through the central processor integration box (11), drive the expansion assembly 6 to work through the first motor, and adjust the direction of the wind direction detector (8) so that the wind direction detector (8) rotates to the windward side. The external wind enters the interior of the air analyzer (10) through the rotating rotating and matching plate (606), and monitor the air through the air analyzer (10); A2. The air flow is led to the fixed plate (601) on the mounting frame (518). The air flow passes through the impurities on the air analyzer (10) and is analyzed to obtain the quantity and type of impurities. When the air pollution is serious and there are more impurities in the air, the first motor drives the gear ring (605) to rotate. Under the support of the rotation force, the adjustment plates (604) connected between the gear rings (605) drive the driving rod (603) in the arc-shaped slide groove (602) to rotate accordingly. The rotating driving rod (603) drives the rotating gear ring (605). The plate (606) rotates around the axis, so that the holes between the plurality of rotating plates (606) are reduced. After the holes are reduced, the air flow is concentrated in the central area of the air analyzer (10), which facilitates the centralized observation and analysis of impurities in the atmosphere. When the air pollution is more serious and there are more impurities in the air, the adjustment plate (604) is rotated to enlarge the holes enclosed by the plurality of rotating plates (606), and the diameter of the air guide wire bundle is increased, so that the impurities are more dispersed on the air analyzer (10), and there is not much overlap between the impurities. A3. Simultaneously, the rotation of the second motor output shaft drives the rotation of the driving gear (512). The driving gear (512) is meshed with the annular gear (510), so that the rotation of the driving gear (512) drives the U-shaped clamping block (508) to make a circular motion on the outside of the annular gear (510). The movement of the U-shaped clamping block (508) drives the adjustment to slide on the outside of the limit ring (507), so that the air analyzer (10) on the top main rod (7) rotates to the windward side. When the staff rotates the platform knob (513), the translation gear (514) ) rotates and meshes with the turntable translation rack (517), and the reaction force from the translation rack (517) pushes the installation platform (501) to move, thereby realizing the translation movement of the installation platform (501) relative to the support frame (515), and at the same time, the rear end installation frame (518) is movably engaged in the two moving grooves (519) through the locking member (516) at the rear end of the support frame (515), and the two locking members (516) at the rear end move vertically relative to the moving grooves (519) on both sides of the installation frame (518) during the translation movement relative to the support frame (515); A4. When it is necessary to change the location for atmospheric detection, an elastic member (403) is provided on the adjusting member (401). As the adjusting member (401) moves, the inner diameter of the conical groove (405) in the connecting kit (404) gradually decreases along one direction at the position corresponding to the movement track of the elastic member (403), so that the elastic member (403) moves from the initial state to the center and gathers to press the probe when moving with the adjusting member (401), or the elastic member (403) deforms from the gathered state to the initial state to loosen the protruding end (406). A threaded member (402) is provided at one end of the conical groove (405) extending into the adjusting member (401), and an internal thread is correspondingly provided on the peripheral wall of the connecting kit (404). The adjusting member (401) rotates in the connecting kit (404), and the cooperation between the internal thread and the threaded member (402) converts the circumferential displacement of the rotation of the adjusting member (401) into a linear displacement along the axial direction, thereby changing the depth of the adjusting member (401) in the connecting kit (404). At the same time, the rotating rod (3) can also be rotated in the reverse direction to make the arc-shaped grooves (408) on both sides, so that the protruding ends (406) on both sides are disengaged from the clamping connection with the rotating rod (3), thus completing the quick disassembly.
