Description

Technical Field

[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

[0033] In order to make the purpose and advantages of the present invention more clear and understandable, the present invention will be further described below in combination with the embodiments; it should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0034] Embodiment 1: Please refer to Figures 1-6As shown in the figure, a manually adjustable sampler for ambient air detection includes a base 1. An inverted "T"-shaped ring groove is formed on the upper surface of the base 1. The base 1 is movably installed with a rotating ring 101 through the inner surface of the ring groove. In the middle of the four sides of the upper surface of the rotating ring 101, guide rods 102 are fixedly provided. On the upper surface of the rotating ring 101 on the side close to each other between the outer surfaces of the guide rods 102, limit rods 103 are fixedly provided;

[0035] By using the base 1 and the rotating ring 101 in cooperation, the rotating ring 101 can rotate within the ring groove formed on the upper surface of the base 1, thereby synchronously driving the guide rods 102 and the limit rods 103 to rotate during the rotation process.

[0036] A collar 2 is movably sleeved on the outer ring surface of the base 1. In the middle of the four sides of the upper surface of the collar 2, adjusting screws 201 are movably installed through bearings. The other ends of the adjusting screws 201 are jointly movably installed with a fixing ring 3. The other ends of the guide rods 102 and the limit rods 103 are connected to the lower surface of the fixing ring 3. In the middle of the inner surface of the fixing ring 3, a fixing plate 301 is fixedly provided. On the upper surface of the fixing plate 301, a micro-meteorological sensor 302 is fixedly installed. On the lower surface of the fixing plate 301, a sampling point predictor 4 is fixedly installed;

[0037] The collar 2 can be used to movably support the adjusting screws 201. Since the other ends of the guide rods 102 and the limit rods 103 are connected to the lower surface of the fixing ring 3, when the guide rods 102 and the limit rods 103 are in a rotating state, they can synchronously drive the fixing ring 3 to rotate. At the same time, since the fixing ring 3 is movably connected to the adjusting screws 201, the adjusting screws 201 can be synchronously driven to rotate during the rotation of the fixing ring 3. By rotating the adjusting screws 201 clockwise or counterclockwise, the adjusting block 6 can be controlled to move vertically up and down. The fixing plate 301 is used to install the micro-meteorological sensor 302 and the sampling point predictor 4. The micro-meteorological sensor 302 is used to monitor the meteorological factors within the monitoring range in real time, and the sampling point predictor 4 is used to predict the sampling points.

[0038] Adjusting blocks 6 are spirally sleeved and movably installed in the middle of the outer surfaces of the adjusting screws 201. On the side close to each other between the outer surfaces of the adjusting blocks 6, arc-shaped limit blocks 5 are fixedly installed. In the middle of the upper surface of the limit block 5, a guiding opening 502 is formed through. The guiding opening 502 is movably sleeved on the outer surface of the guide rod 102. At both ends of the outer surface of the limit block 5, limiting openings 501 are formed. The limiting openings 501 are movably sleeved on the outer surface of the limit rod 103;

[0039] By using the limit blocks 5 in cooperation with the guide rods 102 and the limit rods 103, the limit rods 103 are used in cooperation with the limiting openings 501 to limit the limit blocks 5. Since the limit blocks 5 are connected to the adjusting blocks 6, the effect of limiting the adjusting blocks 6 is achieved.

[0040] On both sides of the lower surface of the adjustment block 6, fixed frames 601 are fixedly installed. In the middle of the lower surface of the fixed frame 601, an internal thread opening is penetrated and provided. Through the inner surface of the internal thread opening of the fixed frame 601, a locking pin 602 is spirally inserted and installed. The output end of the locking pin 602 is movably installed with a locking block 603 through a bearing. A sampling cylinder 7 is installed in a clamping manner on the inner surface of the fixed frame 601. An air suction valve 701 is fixedly installed at the air inlet end of the sampling cylinder 7. An air suction pipe 702 is fixedly installed at the exhaust port end of the sampling cylinder 7. The air suction pipe 702 is arranged in a corrugated stacked structure;

[0041] By screwing the locking pin 602 clockwise and counterclockwise, the extension length of its output end in the fixed frame 601 can be controlled, so as to adjust the position of the locking block 603 in the fixed frame 601. The sampling cylinder 7 is locked and fixed by the cooperation of the locking block 603 and the fixed frame 601. The air collection sample is transmitted through the cooperation of the sampling cylinder 7 and the air suction pipe 702. When the air suction pipe 702 is in a corrugated stacked structure, arbitrary adjustment of various transmission lengths can be realized. The sampling cylinder 7 can be hermetically protected by the air suction valve 701 in the non-sampling state to avoid the problem that its internal pollution affects sampling. When in the sampling state, negative pressure will be generated in the sampling cylinder 7 to control the opening of the air suction valve 701, and the air sample can enter the sampling cylinder 7 for collection and transmission.

[0042] In the middle of the four sides of the lower surface of the base 1, support legs 104 are fixedly provided. In the middle of the inner surface of the support legs 104, a support plate 105 is fixedly installed together. In the middle of the upper surface of the support plate 105, a sampler 8 is fixedly installed. In the middle of the upper surface of the sampler 8, a sampling pipe 801 is fixedly provided. A tray 802 is movably installed on the inner surface of the other end of the sampling pipe 801. In the middle of both sides of the outer surface of the tray 802, adjustment ears 803 are fixedly provided. The other end of the adjustment ear 803 penetrates the sampling pipe 801 and extends outside. The middle of the upper surface of the tray 802 is arranged in a concave shape. A second sealing plug 902 is placed in an embedded manner through the inner surface of the concave part of the tray 802;

[0043] The sampler 8 can be supported and installed through the cooperation of the support legs 104 and the support plate 105. The air sample can be collected through the cooperation of the sampler 8 and the sampling pipe 801. 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 pipe 801, and the adjustment ear 803 is 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 provided on the lower surface of the sample storage bottle 9 to seal the sample storage bottle 9.

[0044] At the other end of the sampling tube 801, an interface 804 is fixedly provided. The sampling tube 801 is fixedly inserted and installed with a sample storage bottle 9 through the inner surface of the interface 804. Openings are respectively formed through the middle parts of the upper and lower surfaces of the sample storage bottle 9. The sample storage bottle 9 is inserted and installed with a first sealing plug 901 through the upper surface opening. The diameter size of the lower surface opening of the sample storage bottle 9 matches the diameter size of the tray 802.

[0045] The sample storage bottle 9 can be placed through the interface 804. When the sampler 8 is used to cooperate with the sampling tube 801 for air sampling, the air sample will pass through the sample storage bottle 9. The two ends of the sample storage bottle 9 are sealed by the first sealing plug 901 and the second sealing plug 902, and then the air sample can be intercepted in the sample storage bottle 9 to complete the sample collection.

[0046] The sampling point predictor 4 includes a database, an analysis module, a prediction module, and a transmission module.

[0047] The database is used to store the deduced data of the distribution state of air pollutants within the monitoring range under different interval states of various meteorological data.

[0048] Specifically, the analysis is as follows: The various meteorological data include temperature, humidity, wind speed, and wind direction data within the monitoring range, and data intervals are preset for each data. The temperature data is set as WD, the humidity data is set as SD, the wind speed data is set as FS, and the wind direction data is set as FX.

[0049] The temperature thresholds (WDa - WDb), (WDb - WDc),... are set as temperature level 1 intervals, level 2 intervals,...

[0050] The humidity thresholds (SDa - SDb), (SDb - SDc),... are set as humidity level 1 intervals, level 2 intervals,...

[0051] The wind speed thresholds (FSa - F Sb), (FSb - FSc),... are set as wind speed level 1 intervals, level 2 intervals,...

[0052] The wind direction is set as wind direction FX1, FX2,... according to different flow directions.

[0053] Based on the preset data intervals and flow directions of various meteorological factors, through the speculation of monitoring personnel on the distribution range and trend of air pollutants, the deduced data of the distribution state of air pollutants within the monitoring range is obtained.

[0054] The analysis module is used to receive each meteorological value real-time monitored by the micro-meteorological sensor 302, match each meteorological value with the preset meteorological data intervals, and obtain the predicted data of the corresponding distribution state of air pollutants based on the matching results and transmit them to the prediction module.

[0055] The specific analysis is as follows: The values of various meteorological factors are monitored in real time through the micrometeorological sensor 302 to obtain the real-time temperature value. and the real-time humidity value and the real-time wind speed value and the wind direction and flow direction . The real-time meteorological values are matched with the preset intervals. If the match is successful, the interval levels corresponding to the real-time monitoring values of various meteorological factors are obtained, and the deduced data of the air pollutant distribution state corresponding to the interval levels are screened to obtain the predicted data of the air pollutant distribution state.

[0056] The prediction module substitutes the predicted data of the air pollutant distribution state obtained into the preset coordinate model within the monitoring range to obtain the coordinates for arranging sampling points.

[0057] The specific analysis is as follows: The pollutant distribution range and trend in the predicted data of the air pollutant distribution state are substituted into the preset coordinate model within the monitoring range, and the coordinates for arranging sampling points are obtained according to the matching results of the coordinate model.

[0058] The transmission module is wirelessly connected to the micrometeorological sensor 302 and the mobile terminals of the monitoring personnel, and is used to obtain the meteorological values monitored in real time by the micrometeorological sensor 302 and transmit them to the analysis module for data analysis, and transmit the obtained coordinates for arranging sampling points to the mobile terminals of the monitoring personnel.

[0059] The specific analysis is as follows: The coordinates for arranging sampling points are transmitted to the mobile terminals of the monitoring personnel through the transmission module. The monitoring personnel can then adjust the sampling position of the sampling cylinder 7 according to the coordinate positions. After adjusting to the coordinate positions, air samples can be collected.

[0060] When the present invention is in use, first, the micrometeorological sensor 302 is used in cooperation with the sampling point predictor 4 to predict the air pollutant distribution state to obtain the sampling point coordinates, and the sampling cylinder 7 is clamped and installed in the fixed frame 601. The locking pin 602 is rotated counterclockwise to control the locking block 603 to approach the sampling cylinder 7 and cooperate with the fixed frame 601 to complete the locking and fixing of the sampling cylinder 7. When the sampling point coordinates are obtained, the rotating ring 101 can be rotated to drive the collar 2 to rotate and adjust. When the collar 2 is in the rotating and adjusting state, the adjusting screw 201 can be synchronously adjusted in position. At this time, the position adjustment of the adjusting screw 201 can be used to drive the synchronous adjustment of the collection orientation of the adjusting block 6. After the adjusting screw 201 is adjusted to the specified position, it can be rotated clockwise or counterclockwise. By rotating the adjusting screw 201 clockwise or counterclockwise, the adjusting block 6 is controlled to move up and down to drive the sampling cylinder 7 to be adjusted to the sampling point coordinates. At this time, the adjustment of the sampling point is completed.

[0061] Next, when the control and adjustment block 6 drives the sampling cylinder 7 to adjust the sampling points, the suction pipe 702 can be stretched and unfolded from the stacked state to achieve the effect of adjusting the transmission length. After the sampling cylinder 7 is adjusted, the other end of the suction pipe 702 can be connected to the opening of the first sealing plug 901 on the storage sample bottle 9. At this time, the sampler 8 can be started to perform negative pressure sampling. At this time, the storage sample bottle 9 and the sampling cylinder 7 will gradually become in a negative pressure state. Under the negative pressure state, the suction valve 701 installed at the air inlet end of the sampling cylinder 7 will open, and thus the external air will be sampled and collected into the sampler 8;

[0062] When the collected air sample enters the sampler 8, it will flow through the storage sample bottle 9 through the suction pipe 702. At this time, the adjustment ear 803 can be pulled out of the sampling pipe 801, and the adjustment ear 803 is used to drive the tray 802 to move upward. During the upward movement of the tray 802, the second sealing plug 902 placed therein can be inserted into the opening formed on the lower surface of the storage sample bottle 9 to seal the storage sample bottle 9. At the same time, the suction pipe 702 is separated from the storage sample bottle 9 and the first sealing plug 901 is used to seal the opening formed on the upper surface of the storage sample bottle 9, and thus the air sample can be intercepted in the storage sample bottle 9 to complete the sample collection.

A collar 2 is movably sleeved on the outer ring surface of the base 1. The middle parts of the four sides of the upper surface of the collar 2 are all movably installed with adjustment screws 201 through bearings. The other ends of the adjustment screws 201 are jointly movably installed with a fixing ring 3. The other ends of the guide rod 102 and the limiting rod 103 are both connected to the lower surface of the fixing ring 3. The middle part of the inner surface of the fixing ring 3 is fixedly provided with a fixing disk 301. A micro-meteorological sensor 302 is fixedly installed on the upper surface of the fixing disk 301. A sampling point predictor 4 is fixedly installed on the lower surface of the fixing disk 301;

[0064] The middle parts of the four sides of the lower surface of the base 1 are all fixedly provided with support legs 104. The middle part of the inner surface of the support legs 104 is jointly fixedly installed with a support disk 105. A sampler 8 is fixedly installed in the middle of the upper surface of the support disk 105. The middle part of the upper surface of the sampler 8 is fixedly provided with a sampling pipe 801,

[0065] The other end of the sampling pipe 801 is fixedly provided with a docking port 804. A storage sample bottle 9 is fixedly inserted and installed through the inner surface of the docking port 804. Openings are respectively formed through the middle parts of the upper surface and the lower surface of the storage sample bottle 9. A first sealing plug 901 is inserted and installed through the upper surface opening of the storage sample bottle 9. The diameter size of the lower surface opening of the storage sample bottle 9 matches the diameter size of the tray 802;

[0066] The sampling point predictor 4 includes a database, an analysis module, and a transmission module;

[0067] The database is used to store the deduced preservation conditions required for air collection samples under different interval states of various meteorological data;

[0068] Specific analysis is as follows: Each meteorological data includes temperature and humidity data within the monitoring range, and preset data intervals are set for each data. The temperature data is set as WD, and the humidity data is set as SD;

[0069] The temperature thresholds (WDa - WDb), (WDb - WDc),... are set as the temperature level 1 interval, level 2 interval,... intervals;

[0070] The humidity thresholds (SDa - SDb), (SDb - SDc),... are set as the humidity level 1 interval, level 2 interval,... intervals;

[0071] Based on the preset data intervals of each meteorological factor, the deduced preservation conditions required for collecting air samples are speculated by the monitoring personnel;

[0072] The analysis module is used to receive each meteorological value real - time monitored by the micro - meteorological sensor 302, match each meteorological value with the preset meteorological data intervals, and obtain the pre - preservation conditions required for collecting air samples based on the matching results;

[0073] Specific analysis is as follows: By real - time monitoring the values of each meteorological factor through the micro - meteorological sensor 302, the real - time temperature value and the real - time humidity value are obtained. Each meteorological real - time value is matched with the preset interval. If the match is successful, the interval level corresponding to each meteorological factor real - time monitoring value is obtained, and the corresponding deduced preservation conditions for collecting air samples are screened according to the interval level, and the pre - preservation conditions required for collecting air samples are obtained;

[0074] The transmission module is wirelessly connected to the micro - meteorological sensor 302 and the mobile terminal of the monitoring personnel, and is used to obtain the meteorological values real - time monitored by the micro - meteorological sensor 302 and transmit them to the analysis module for data analysis, and transmit the obtained pre - preservation conditions for collecting air samples to the mobile terminal of the monitoring personnel;

[0075] Specific analysis is as follows: The sample pre - preservation conditions are transmitted to the mobile terminal of the monitoring personnel through the transmission module. The monitoring personnel can then adjust the preservation conditions of the sample storage bottle 9 according to the pre - preservation conditions, and the air sample can be preserved after the adjustment is completed.

[0076] When the present invention is in use, first, the micro-meteorological sensor 302 and the sampling point predictor 4 can be used to predict the preservation conditions of the air sample collection, so as to obtain the pre-preservation conditions. At this time, the sample storage bottle 9 can be adjusted specifically according to the pre-preservation conditions. Then, the other end of the suction pipe 702 after the adjustment of the sampling cylinder 7 is communicated with the opening of the first sealing plug 901 on the sample storage bottle 9, and the sampler 8 is started to perform negative pressure sampling. At this time, the sample storage bottle 9 and the sampling cylinder 7 will gradually become in a negative pressure state. Under the negative pressure state, the suction valve 701 installed at the air inlet end of the sampling cylinder 7 will open, so as to start extracting the external air sample and collecting it into the sampler 8. When the collected air sample enters the sampler 8, it will flow through the adjusted sample storage bottle 9 through the suction pipe 702. At this time, the second sealing plug 902 and the first sealing plug 901 are used to seal the openings provided at both ends 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 and preservation.

[0077] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
