Description

[0001] The present invention relates to the technical field of samplers, and in particular to a manually adjustable sampler for environmental air detection. Background Art

[0002] Ambient air monitoring refers to the fixed-point, continuous or timed sampling and measurement of pollutants in the atmosphere to assess air quality conditions. The existing air monitoring sampling method mainly sets up air monitoring points at fixed locations and collects test samples through air samplers.

[0003] However, pollutants in the air can be affected by natural factors, which may cause their distribution to change, thus affecting the results of sampling and detection. In order to ensure the accuracy of air detection results, the sampling points need to be adjusted according to the changes in the distribution of pollutants in the air. At the same time, since the air samplers at air monitoring points are usually set in a fixed state, the sampling points are not easy to adjust according to the distribution changes of pollutants in the air, resulting in a certain degree of error in sample collection. To this end, we propose a manually adjusted sampler for ambient air detection. Summary of the invention

[0021] The outer ring surface of the base 1 is movably sleeved with a collar 2, and the middle parts of the four sides of the upper surface of the collar 2 are movably mounted with adjusting screws 201 through bearings, and the other end of the adjusting screw 201 is movably mounted with a fixing ring 3, and the other ends of the guide rod 102 and the limit rod 103 are connected to the lower surface of the fixing ring 3, and a fixing plate 301 is fixedly mounted in the middle part of the inner surface of the fixing ring 3, and a micro-meteorological sensor 302 is fixedly mounted on the upper surface of the fixing plate 301, and a sampling point predictor 4 is fixedly mounted on the lower surface of the fixing plate 301; The adjusting screw 201 can be movably supported by the sleeve ring 2. Since the other ends of the guide rod 102 and the limit rod 103 are connected to the lower surface of the fixed ring 3, when the guide rod 102 and the limit rod 103 are in a rotating state, the fixed ring 3 can be synchronously driven to rotate. At the same time, since the fixed ring 3 is movably connected to the adjusting screw 201, the adjusting screw 201 can be synchronously driven to rotate during the rotation of the fixed ring 3. The adjusting block 6 can be controlled to perform vertical lifting and lowering movement by rotating the adjusting screw 201 clockwise or counterclockwise. The micrometeorological sensor 302 and the sampling point predictor 4 are installed through the fixed plate 301. The meteorological factors within the monitoring range are monitored in real time through the micrometeorological sensor 302, and the sampling points are predicted through the sampling point predictor 4.

The limit block 5 is used in conjunction with the guide rod 102 and the limit rod 103, and the limit rod 103 is used in conjunction with the limit opening 501 to limit the limit block 5.

The sampling tube 7 is locked and fixed by the locking block 603 in cooperation with the fixed frame 601. The air collection sample is transmitted by the sampling tube 7 in cooperation with the suction pipe 702. When the suction pipe 702 is a corrugated stacking structure, various transmission lengths can be arbitrarily adjusted. The sampling tube 7 can be sealed and protected by the suction valve 701 when not collecting, avoiding the problem of internal contamination affecting sampling. When in the collection state, negative pressure will be generated in the sampling tube 7, thereby controlling the suction valve 701 to open, and the air sample can enter the sampling tube 7 for collection and transmission.

[0024] Support legs 104 are fixedly provided in the middle of the four sides of the lower surface of the base 1, and a support plate 105 is fixedly installed in the middle of the inner surface of the support legs 104. A sampler 8 is fixedly installed in the middle of the upper surface of the support plate 105. A sampling tube 801 is fixedly provided in the middle of the upper surface of the sampler 8. A tray 802 is movably installed on the inner surface of the other end of the sampling tube 801. Adjustment ears 803 are fixedly provided in the middle of both sides of the outer surface of the tray 802. The other end of the adjustment ear 803 passes through the sampling tube 801 and extends outside. The middle of the upper surface of the tray 802 is concave, and a second sealing plug 902 is embedded and placed on the inner surface of the concave part of the tray 802. The sampler 8 can be supported and installed by the support legs 104 and the support plate 105. The sampler 8 can be used in conjunction with the sampling tube 801 to collect air samples. The second sealing plug 902 is fixed by the tray 802. After the sample collection is completed, the adjustment ear 803 can be pulled out of the sampling tube 801. The adjustment ear 803 can be used to drive the tray 802 to move up and down. During the rising process of the tray 802, the second sealing plug 902 placed therein can be inserted into the opening on the lower surface of the sample storage bottle 9 to seal the sample storage bottle 9.

The middle parts of the upper surface and the lower surface of the sample storage bottle 9 are penetrated with openings, and the first sealing plug 901 is inserted and installed through the upper surface opening of the sample storage bottle 9. The diameter of the lower surface opening of the sample storage bottle 9 matches the diameter of the tray 802. The sample storage bottle 9 can be placed through the docking port 804. When the sampler 8 cooperates with the sampling tube 801 to perform air extraction sampling, the air sample will pass through the sample storage bottle 9. The openings at both ends of the sample storage bottle 9 will be sealed by the first sealing plug 901 and the second sealing plug 902, so that the air sample can be intercepted in the sample storage bottle 9 to complete the sample collection.

[0026] The sampling point predictor 4 includes a database, an analysis module, a prediction module, and a transmission module; The database is used to store the distribution state deduction data of air pollutants within the monitoring range under different intervals of meteorological data; The specific analysis is as follows: each meteorological data includes the temperature, humidity, wind speed and wind direction data within the monitoring range, and the data interval of each data is preset, the temperature data is set to WD, the humidity data is set to SD, the wind speed data is set to FS, and the wind direction data is set to FX; The temperature thresholds (WDa-WDb), (WDb-WDc), ... are set as temperature level 1 interval, level 2 interval, ... intervals; The humidity thresholds (SDa-SDb), (SDb-SDc), ... are set as humidity level 1 interval, level 2 interval, ... interval; The wind speed thresholds (FSa-FSb), (FSb-FSc), ... are set to wind speed level 1 interval, level 2 interval, ... interval; Set the wind direction to FX1, FX2, ... according to the flow direction; Based on the preset data intervals and flow directions of various meteorological factors, monitoring personnel infer the distribution range and direction of pollutants in the air, and obtain the distribution state deduction data of pollutants in the air within the monitoring range; The analysis module is used to receive various meteorological values ​​monitored in real time by the micro-meteorological sensor 302, and match each meteorological value with a preset meteorological data interval, and obtain distribution state prediction data corresponding to pollutants in the air based on the combination of matching results and transmit it to the prediction module; The specific analysis is as follows: the micro-meteorological sensor 302 monitors the values ​​of various meteorological factors in real time to obtain the real-time temperature value. , Real-time humidity value , Real-time value of wind speed , wind direction , match each meteorological real-time value with the preset interval. If the match is successful, the interval level corresponding to the real-time monitoring value of each meteorological factor is obtained, and the corresponding air pollutant distribution state deduction data is screened according to the interval level to obtain the air pollutant distribution state prediction data; The prediction module substitutes the obtained prediction data of the distribution state of pollutants in the air into the preset coordinate model within the monitoring range to obtain the sampling point layout coordinates; The specific analysis is as follows: the pollutant distribution range and direction in the predicted data of the distribution state of pollutants in the air are substituted into the preset coordinate model within the monitoring range, and the sampling point layout coordinates are obtained according to the matching results of the coordinate model; The transmission module is connected to the micro-meteorological sensor 302 and the mobile terminal of the monitoring personnel through wireless signals, and is used to obtain the meteorological values ​​monitored in real time by the micro-meteorological sensor 302 and transmit them to the analysis module for data analysis, and transmit the obtained sampling point layout coordinates to the mobile terminal of the monitoring personnel; The specific analysis is as follows: the sampling point layout coordinates are transmitted to the monitoring personnel's mobile terminal through the transmission module, and the monitoring personnel can control the sampling tube 7 to adjust the sampling position according to the coordinate position, and the air sample can be collected after it is adjusted to the coordinate position.

[0027] When the present invention is in use, first, the distribution state of pollutants in the air can be predicted through the micro-meteorological sensor 302 in cooperation with the sampling point predictor 4 to obtain the sampling point coordinates, and the sampling tube 7 is clamped and installed in the fixed frame 601, and the locking pin 602 is turned counterclockwise to control the locking block 603 to move toward the sampling tube 7 and close to the fixed frame 601 to complete the locking and fixing of the sampling tube 7. When the sampling point coordinates are obtained, the rotating ring 101 can be rotated to drive the sleeve ring 2 to rotate and adjust. When the sleeve ring 2 is in the rotation adjustment state, it can synchronously drive the adjusting screw 201 to adjust the position. At this time, the position adjustment of the adjusting screw 201 can be used to drive the adjusting block 6 to synchronously adjust the collection direction. When the adjusting screw 201 is adjusted to the specified position, it can be rotated clockwise and counterclockwise. The adjusting screw 201 is rotated clockwise and counterclockwise to control the adjusting block 6 to perform lifting and lowering adjustment to drive the sampling tube 7 to adjust to the sampling point coordinates. At this time, the adjustment of the sampling point can be completed; Secondly, when the control adjustment block 6 drives the sampling tube 7 to adjust the sampling point, the suction tube 702 can be stretched and unfolded from the stacked state to achieve the effect of adjusting the transmission length. After the adjustment of the sampling tube 7 is completed, the other end of the suction tube 702 can be connected to the opening of the first sealing plug 901 on the sample storage bottle 9. At this time, the sampler 8 can be started to start negative pressure sampling. At this time, the sample storage bottle 9 and the sampling tube 7 will gradually change to a negative pressure state. Under the negative pressure state, the suction valve 701 installed at the air inlet end of the sampling tube 7 will open, thereby starting to extract samples of the external air and collect them into the sampler 8; When the collected air sample enters the sampler 8, it will flow through the sample storage bottle 9 through the suction pipe 702. At this time, the adjustment ear 803 can be pulled out from the sampling tube 801, and the adjustment ear 803 can be used to drive the tray 802 to move upward. During the rising process of the tray 802, the second sealing plug 902 placed in it can be inserted into the opening opened on the lower surface of the sample storage bottle 9 to seal the sample storage bottle 9. At the same time, the suction pipe 702 is separated from the sample storage bottle 9 and the first sealing plug 901 is used to seal the opening opened on the upper surface of the sample storage bottle 9, so that the air sample can be intercepted in the sample storage bottle 9 to complete the sample collection.
