Description

Technical Field

[0001] The present invention relates to the technical field of atmosphere monitoring, and in particular to a portable atmosphere detection device and method with dynamic drainage. Background Art

[0002] To overcome the shortcomings of traditional atmospheric monitoring equipment and meet diverse monitoring needs, portable atmospheric monitoring equipment with dynamic drainage has emerged. This device integrates advanced sensor technology, an efficient dynamic drainage system, and a convenient data processing and transmission module. By actively collecting atmospheric samples through dynamic drainage technology, it significantly improves detection efficiency and accuracy. Its compact size and portability make it suitable for monitoring tasks in a variety of complex environmental conditions, providing a new and efficient solution for atmospheric environmental monitoring.

[0003] Currently, some portable atmospheric monitoring equipment uses gas guides, such as needles, to switch between gas cylinders, enabling sample collection under different testing environments. However, when switching between gas cylinders, these gas guides inevitably retain the previous sample, causing contamination of subsequent samples and biased test results.

[0004] Furthermore, dust, particulate matter, and some sticky contaminants in the atmosphere easily adhere to the inner walls of the testing equipment's pipes. Over time, these deposits accumulate in the pipes, altering the gas flow characteristics within them and affecting smooth gas transmission. They can also chemically react with subsequently collected samples, interfering with the accuracy of test results.

[0005] For example, the Chinese patent publication number CN119915969A discloses a portable atmospheric detection device, which includes: a casing, with rollers installed at the four corners of the lower end face; an air intake bin, arranged on the inner upper side of the casing, and a plurality of air slots distributed circumferentially on the upper end face of the air intake bin; a circulating air supply unit, vertically arranged in the casing, and the upper end of the circulating air supply unit is connected to the air intake bin; an exhaust bin, fixed in the casing and located directly below the circulating air supply unit, and an exhaust channel is provided on one side of the exhaust bin; an air sampling unit, installed in the casing, and a sampling pipe is connected between the air sampling unit and the circulating air supply unit; it can realize efficient dynamic drainage and high-frequency continuous sampling of environmental airflow, significantly improving the accuracy and reliability of atmospheric detection.

[0006] However, the above portable atmospheric detection device still has some shortcomings in actual use: 1. The above-mentioned device can achieve efficient dynamic drainage of ambient airflow and high-frequency continuous sampling. However, during the drainage process, the gas guide device may retain the previous sample when switching gas cylinders, causing cross-contamination of subsequent samples, seriously interfering with the accuracy of the test results, and failing to truly reflect the actual atmospheric conditions.

[0007] 2. Debris may remain in the pipes. Over time, various atmospheric substances will accumulate on the inner walls of the pipes, gradually forming stubborn deposits. These deposits may absorb key pollutants in the sample, causing the testing instrument to misjudge the type and content of the pollutants, resulting in distorted atmospheric testing data and an inability to provide a reliable basis for environmental monitoring and remediation.

[0008] Therefore, based on the above-stated viewpoints, it is of great significance to improve and perfect the portable atmospheric detection device, which can not only ensure that the samples will not be cross-contaminated and the accuracy of the test results, but also clean the attachments in the pipeline and further ensure the accuracy of the test data.

DETAILED DESCRIPTION

[0037] The following combination Figures 1-8 The embodiments of the present invention are described in detail.

[0038] The embodiment of the present application discloses a portable atmospheric detection device and method with dynamic drainage. The present invention is mainly used in the process of atmospheric monitoring. In terms of technical effect, it can avoid the problem that during the drainage process, the gas guide device may retain the previous sample when switching gas cylinders, causing cross-contamination of subsequent samples and seriously interfering with the accuracy of the detection results; further, the present invention can also solve the problem that residual attachments may remain in the pipeline, which will affect the collection effect if not cleaned.

[0039] Example 1: Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, a portable atmospheric detection device with dynamic drainage includes a mobile frame 1, on which a detection box 10 is installed. The detection box 10 is moved by the mobile frame 1, making the detection more portable and convenient to move. A support block 11 is rotatably installed inside the detection box 10, and a clamping groove 12 is provided on the support block 11. A loading piece 2 is installed on one side of the length direction of the detection box 10. The present application uses a method of placing an atmospheric sample in an existing sample bottle for detection. A detector (not shown in the figure) is provided in the detection box 10 to inspect the bottle body after collecting the sample. The detector is preferably an existing portable detector for detecting atmospheric quality, which will not be described in detail herein.

[0040] The clamping groove 12 on the support block 11 plays the role of supporting the sample bottle to facilitate the material collection. A plurality of sample bottles are gradually placed in the clamping groove 12 by the loading member 2.

[0041] A collecting piece 3 connected to the interior is provided on the outside of the detection box 10 along its width direction; the collecting piece 3 includes a fixed box 30, and a collecting tube 31 extending to the interior of the detection box 10 is provided inside the fixed box 30 along its width direction. The air is collected by the collecting piece 3 and enters the sample bottle, and the air enters the detection box 10 through the collecting tube 31.

[0042] The detection box 10 is provided with a cleaning member 4 for cleaning the collection tube 31. Since only a single collection tube 31 is used during the air collection process, and different samples are placed in different sample bottles, when sampling at different locations twice, the air sample collected at the previous location will remain in the collection tube 31. This will cause the remaining air to enter the sample bottle first when air is introduced into the sample bottle the next time, resulting in distorted sample detection results. Therefore, the cleaning member 4 cleans the collection tube 31 to ensure that no air sample remains in the collection tube 31, thereby ensuring the accuracy of the detection.

[0043] The cleaning unit 4 comprises a mounting block 40, which defines a connecting chamber 41. A sealing plate 42 is slidably mounted along its height. A nozzle 43 is mounted on the sealing plate 42. A storage tank 44 is located within the test chamber 10, and the nozzle 43 communicates with the interior of the storage tank 44 via a pipe. After sampling is complete, the sealing plate 42 descends to seal the collection tube 31. An air pump then pumps the air within the test chamber 10 through the pipe and out of the nozzle 43, clearing the collection tube 31.

[0044] The storage box 44 stores inert gas, which is used to clean the collection tube 31. During the blowing process, the sample can be prevented from adhering to the inner wall of the collection tube 31. The adhering dust, condensation of water vapor and other impurities can be removed by blowing, thereby ensuring the accuracy of sample detection.

[0045] Reference Figure 1 and Figure 4 As shown, it is a structural diagram of gradually placing the sample bottles in the clamping groove 12; specifically, the loading part 2 includes a square placement tube 20, a conveyor belt 21 is provided in the placement tube 20, and support plates 22 are equidistantly installed on the conveyor belt 21. A discharge port is provided on the side of the placement tube 20 close to the support block 11, and a baffle 23 is provided along its length direction at the discharge port, and a through groove corresponding to the support plate 22 is provided on the baffle 23.

[0046] Multiple samples are gradually placed in the placement tube 20, and the sample bottles are placed between multiple support plates 22. Through the rotation of the conveyor belt 21, multiple sample bottles can be brought close to the discharge port at one time and enter the clamping groove 12 from the direction of the discharge port.

[0047] An arc-shaped plate 24 connected to the mounting pipe and sleeved on the outside of the support block 11 is provided in the detection box 10 .

[0048] After the sample bottle enters the clamping groove 12, it will be rotated by the support block 11 so that the sample bottle is aligned with the collection tube 31, which is convenient for sampling. During the rotation process, the curved plate 24 always conflicts with the sample bottle to prevent the sample bottle from falling due to the lack of rigid support during the rotation of the support block 11.

[0049] Reference Figure 5 、 Figure 6 and Figure 7 As shown, it is a structural diagram of moving the air in the collection tube 31 into the sample bottle; specifically, a slide groove communicating with the connecting chamber 41 is provided inside the placement block 40, and a connecting needle 45 is slidably provided inside the slide groove.

[0050] A working chamber connected to the slide groove is further provided inside the placement block 40 , a driving screw 46 is rotatably provided inside the working chamber, a connecting block 47 is threadedly provided on the driving screw 46 , and one end of the connecting block 47 is connected to the connecting needle 45 .

[0051] When the clamping groove 12 corresponds to the collecting tube 31, the driving screw 46 is driven to rotate by external driving, and the connecting block 47 on the driving screw 46 brings the connecting needle 45 closer to the sample bottle. It should be noted at this time that a rubber layer is provided at the opening of the sample bottle, and the connecting needle 45 will gradually penetrate into the rubber layer. At this time, the air in the collecting tube 31 will enter the sample bottle through the connecting needle 45 when passing through the working gun, thereby collecting air samples. Due to the setting of the rubber layer, the gas will not leak after the connecting needle 45 is removed, and the pinhole will be directly covered.

[0052] Reference Figure 5 、 Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for controlling the air to enter the collection tube 31 ; specifically, the support block 11 is arranged inside the detection box 10 through a rotating shaft, and the detection box 10 is also provided with a control member 6 for sucking air into the collection tube 31 .

[0053] The control member 6 includes a mounting block 60 slidably arranged along the height direction of the fixing box 30 . The mounting block 60 is provided with two through holes corresponding to the movement of the collecting pipe 31 . Fans 61 are provided inside the two through holes.

[0054] By sliding the mounting block 60, the fans 61 in the two through holes are respectively aligned with the collection tube 31, and the rotation directions of the two fans 61 are opposite. The upper fan 61 can draw external air into the collection tube 31 for use during the sampling process.

[0055] The fan 61 below can suck out the gas in the collection pipe 31. After the impurities in the collection pipe 31 are pushed out by the inert gas, the excess gas can be taken out by the fan 61 to ensure that the collection pipe 31 is in a clean state.

[0056] Reference Figure 5 、 Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for controlling the lifting of the mounting block 60 ; specifically, the detection box 10 is further provided with a driving member 62 for controlling the sliding of the mounting block 60 ; the driving member 62 includes a connecting rope 1 620 and a connecting rope 2 621 .

[0057] The rotating shaft passes through the detection box 10 and is installed with a roller 622. One end of the connecting rope 1 620 is connected to the upper end of the mounting block 60 and the other end is wound on the roller 622. One end of the connecting rope 2 621 is set at the lower end of the mounting block 60, and the other end is wound on the roller 622.

[0058] When the shaft rotates counterclockwise, the connecting rope 1 620 on the roller 622 is gradually loosened, and the connecting rope 2 621 is gradually wound around the roller 622. At this time, the connecting rope 2 621 will pull the mounting block 60 to move downward, so that the upper fan 61 corresponds to the collection pipe 31, and the collection work is carried out at this time. When the shaft rotates clockwise, the connecting rope 1 620 is gradually wound around the roller 622, and the connecting rope 2 621 is gradually loosened. At this time, the mounting block 60 will move upward under the pull of the connecting rope 1 620 to perform cleaning work.

[0059] Reference Figure 5 As shown, it is a schematic diagram of the structure for collecting the sample after the sampling is completed; specifically, a slider 50 is slidably provided on one side of the width direction of the detection box 10, and an electric push rod 51 is provided on the slider 50, and a push plate 52 is connected to the telescopic end of the electric push rod 51.

[0060] After the sampling is completed, the electric push rod 51 extends, and the push plate 52 on the electric push rod 51 pushes the slider 50 toward the clamping groove 12, pushing out the sample bottle in the clamping groove 12 to complete the collection.

[0061] Reference Figure 3 As shown, it is a schematic diagram of the structure for storing sample bottles after collection; specifically, there is a storage element 7 on one side of the width direction of the detection box 10; the storage element box includes a storage cylinder 70, and multiple groups of guide plates 71 are arranged in the storage cylinder 70 by torsion springs.

[0062] After being pushed out, the sample bottle will fall onto the guide plate 71 in the storage tube 70. After falling onto the guide plate 71, the sample bottle will gradually twist under the action of its gravity, and the sample bottle will gradually fall from top to bottom. The sample bottle will be supported and placed by multiple groups of guide plates 71.

[0063] Reference Figure 5 、 Figure 7 and Figure 8 , which is a schematic diagram of the structure for filtering and cleaning impurities within the collection pipe 31. Specifically, a filter screen 81 is installed in the collection pipe 31 via a spring tube on the side of the mounting block 60 near the collection pipe 31. The purpose of the filter screen 81 is to prevent impurities in the collection pipe 31 from clogging in the collection pipe 31 or adhering to the fan 61 during the cleaning process, causing the detection instrument to misjudge the type and content of pollutants, resulting in distorted atmospheric detection data and an inability to provide a reliable basis for environmental monitoring and treatment.

[0064] The detection box 10 is provided with an extension slot 82 for the filter 81 to slide. A bending slot 83 is provided on the side wall of the extension slot 82 . A matching block 84 is mounted on the side wall of the filter 81 to slide inside the bending slot 83 .

[0065] When the filter screen 81 is lowered along with the mounting block 60, the mating block 84 on the filter screen 81 will cooperate with the bending groove 83, driving the spring tube to expand and contract, so that the filter screen 81 moves back and forth along the width direction of the extension groove 82, producing a certain vibration effect on the filter screen 81, and removing impurities on the filter screen 81 through vibration.

[0066] The bottom of the extension groove 82 is set to be inclined downward, and a collection box 85 connected to the extension groove 82 is installed in the fixing box 30. The cleaned impurities will enter the collection box 85 through the extension groove 82.

[0067] During operation: In the first step, the sample bottle in the placement tube 20 enters the clamping groove 12 through the conveyor belt 21, and then the shaft rotates, and the support block 11 brings the sample bottle in the clamping groove 12 to correspond to the collection tube 31.

[0068] Step 2: Control the driving screw 46 to rotate, and the connecting block 47 on the driving screw 46 carries the connecting needle 45 into the sample bottle. During the rotation, the connecting rope 1 620 on the roller 622 is gradually loosened, and the connecting rope 2 621 is gradually wound around the roller 622. At this time, the connecting rope 2 621 will pull the mounting block 60 to move downward, so that the fan 61 above corresponds to the collection tube 31. At this time, the fan 61 rotates to suck air into the collection tube 31 for collection.

[0069] Step 3: After the collection is completed, the push plate 52 on the electric push rod 51 pushes the sample bottle to drop into the storage tube 70 for placement.

[0070] Step 4: After sampling is complete, the sealing plate 42 seals the collection tube 31. The air pump then pumps the air in the detection chamber 10 through the pipe and out the nozzle 43, clearing the collection tube 31. The shaft then rotates in the opposite direction, and the clamping groove 12 on the support block 11 aligns with the placement tube 20 again, allowing the sample bottle to be placed in the clamping groove 12 again.

[0071] Step 5: During this process, connecting rope 1 620 is gradually wound around the roller 622, and connecting rope 2 621 is gradually loosened. At this time, the mounting block 60 will move upward under the pull of connecting rope 1 620, and the fans 61 above and below the mounting block 60 correspond to the collection pipe 31 and cooperate with the nozzle 43 to clean the collection pipe 31.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
