Description

Technical Field

[0001] This invention relates to the field of soil gas collection devices, and specifically to a soil gas collection device. Background Technology

[0002] The number of soil gas sampling points should be sufficient to characterize the current pollution status of the site. During the soil gas confirmation sampling phase, at least three soil gas sampling points should be set up for each contaminated site. A grid layout can be used during the sampling phase, with appropriately increased sampling density in heavily polluted areas. Existing soil gas sampling methods include various probe layouts in the subsurface soil, such as 4-meter 1-probe active sampling wells, 4-meter 4-probe active sampling wells, and 4-meter 30-probe active sampling wells. The implementation method for the 4-meter 30-probe active sampling well is as follows: Workers drill the well to a depth of 4 meters, first placing 1 cm of quartz sand, then lowering the probe to a position of 3.99 meters. Next, 5 cm of quartz sand, 2 cm of dry bentonite, and 2 cm of wet bentonite are placed. This process is repeated, with probe spacing of 10 cm, from 3.99 meters down to 1.09 meters. The final meter is filled with cement until sealed. However, during this construction process, we found that each probe's connecting tube needed to be labeled and categorized, and the tube openings needed to be sealed with tape. This process consumed a significant amount of the operators' time, and manual labeling inevitably led to errors. In subsequent gas sampling, operators had to manually sieve the tubes by visually inspecting the labels in order to find the probes at the corresponding depths for gas sampling, which affected the progress of soil gas collection. Directly selecting tubes randomly for soil gas collection was also inconvenient for data integration and recording, reducing the efficiency of soil gas sampling. Chinese patent document CN112903379A discloses an automatic soil gas collection device, belonging to the field of soil gas collection technology. It includes a housing, a gas collection device, gas storage components, a pre-storage device, a first transfer device, a conveying device, a second transfer device, and a storage device. The pre-storage device stores multiple gas storage components. The first transfer device transfers these components one by one to the conveying device. The gas collection device inflates the gas storage components. The second transfer device transfers the inflated gas storage components to the storage device for storage. After sampling, workers simply open the second housing to retrieve the storage device, significantly reducing workload and improving efficiency and sampling accuracy. However, this technical solution does not disclose the technology for rapid screening and docking of multiple gas tubes corresponding to multiple probes for collection.

[0003] Therefore, we provide a soil gas sampling device. Operators can quickly and easily connect the gas tubes to the markings on the label plate, replacing manual labeling and reducing the labeling error rate. The controller automatically collects soil gas from multiple gas tubes and probes, eliminating the need for manual connection and collection, thus improving the efficiency of soil gas sampling. The gas storage component automatically collects soil gas from the corresponding gas tubes, avoiding the possibility of incorrect connection or incorrect label data due to manual connection of gas tubes. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention provides a soil gas sampling device. Operators can easily align and connect gas tubes to markings on a labeling plate, replacing tedious manual labeling operations, reducing the probability of incorrect labeling, and saving operators time spent on labeling and classifying gas tubes.

[0022] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the specific implementation methods, structures, features, and effects of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0023] In the description of this application, it should be understood that the orientation or positional relationship indicated by terms such as "inner" and "outer" are based on the orientation or position shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, a specific orientation structure and operation, and therefore should not be construed as a limitation of this application.

[0024] See Figures 1 to 16 This invention discloses a soil gas sampling device, comprising a soil gas sampling well and multiple probes 7 distributed in the soil gas sampling well. The multiple probes 7 are connected to multiple air tubes 6, and the multiple air tubes 6 are connected to an air tube arrangement assembly. A gas sampling component is slidably connected to the air tube arrangement assembly, and the gas sampling component is connected to a gas storage component. The gas sampling component collects soil gas from the probes 7 through the air tube arrangement assembly, and the gas storage component collects soil gas from the air tubes 6 through the gas sampling component. The air tube arrangement assembly includes a frame 1, a dividing plate 2 hinged to the frame 1, multiple straight-through quick connectors 10 provided on the dividing plate 2, and a quick-release plate 9 slidably connected to the dividing plate 2 to cooperate with the straight-through quick connectors 10. The air tube arrangement assembly is connected to the multiple air tubes 6 correspondingly through the multiple straight-through quick connectors 10 on the dividing plate 2. The gas collection component includes a slide module detachably connected to the frame 1. A rotary manipulator 4 is slidably connected to the slide module. The rotary manipulator 4 is rotatably connected to a first mating head 401 and a second mating head 402 corresponding to the straight quick connector 10. The gas collection component extracts gas from the gas tube 6 through the second mating head 402 in conjunction with the straight quick connector 10. The gas storage component includes a turntable 8 located on one side of the slide module. A storage belt 802 is rotatably connected to the turntable 8. An injection head 16 communicating with the second mating head 402 is provided on the turntable 8. Multiple gas storage components 17 are provided on the storage belt 802. The gas storage component collects the soil gas extracted by the gas collection component into the gas storage components 17 through the injection head 16.

[0025] In this embodiment, it should be noted that: the label plate 2 is provided with numerical labels corresponding to multiple straight quick connectors 10, which are arranged in an orderly manner from 1 to 30. The quick-release plate 9 is also provided with numerical labels from 1 to 30, which correspond to the numerical labels on the label plate 2. This arrangement makes it convenient for operators to quickly insert the probe 7 and air tube 6 from deep to shallow according to the corresponding numerical labels on the quick-release plate 9. The orderly arrangement of the label plate 2 eliminates the need for tedious manual edge application and reduces the probability of labeling errors. Multiple gas storage units 17 are respectively equipped with labels corresponding to the digital labels on the labeling plate 2. The transmission belt 801 drives the storage belt 802 to move. When the sensor 19 detects the label on the gas storage unit 17, it transmits the signal data to the controller. The controller controls the transmission belt 801 to stop moving and controls the multi-axis slide group 3 to drive the rotary manipulator 4 to move so that it is above the straight quick connector 10 corresponding to the gas storage unit 17. At this time, the rotary manipulator 4 rotates so that the first mating head 401 is aligned with the straight quick connector 10. The multi-axis slide group 3 drives the rotary manipulator 4 to descend. After the electromagnetic block 4011 on the first mating head 401 is energized, it contacts the magnetic sealing cover 1011 and attracts it. The multi-axis slide group 3 drives the first mating head 401 and its magnetic sealing cover 1011 to rise so that the straight quick connector 10 contacts the seal. After the rotary manipulator 4 rotates again to align the second mating head 402 with the straight quick connector 10, the multi-axis slide group 3 drives the second mating head 402 to descend so that it contacts and connects with the straight quick connector 10. The air pump 11 extracts soil gas from the air pipe 6 and probe 7 connected to the straight quick connector 10 through the air extraction pipe 4021, and transmits the extracted soil gas to the injection head 16 through the connecting pipe 12, valve box 13, and air outlet pipe 14. The lifting part of the elevator 15 drives the injection head 16 to descend so that it connects with the gas storage device 17 and injects soil gas. The elevator 15 then drives the injection head 16 to rise again. The transmission belt 801 continues to run until the sensor 19 detects the gas storage device 17 again. This cycle continues until the sensor 19 detects all the gas storage devices 17 on the storage belt 802, and then the soil gas collection work of the sampling well is completed.

[0026] See Figures 2 to 7 The frame 1 is rotatably connected to a card plate 101, the card plate 101 is provided with a first card protrusion 102, the label plate 2 is provided with a second card protrusion 201 that cooperates with the first card protrusion 102, and multiple straight quick connectors 10 are arranged in an array on the label plate 2.

[0027] In this embodiment, it should be noted that: by rotating the opening plate 101, the limiting position of the plate 101 on the label plate 2 is released, allowing the label plate 2 to be flipped down, so that the quick-release plate 9 is almost in a vertical state, which facilitates the operator to perform the corresponding insertion operation of the air tube 6, bringing convenience to the operator. After the air tube 6 insertion operation is completed, the label plate 2 is flipped up again to cooperate with the plate 101 to limit it.

[0028] See Figures 13 to 14 The quick-release plate 9 has multiple through holes 903 corresponding to the straight quick connector 10. One end of the air tube 6 passes through the through hole 903 and connects to the straight quick connector 10. The quick-release plate 9 is provided with a slide rod 901 that is slidably connected to the label plate 2. A spring 902 is sleeved on the slide rod 901 and located between the quick-release plate 9 and the label plate 2. The outer edge of the through hole 903 is smaller than the outer edge of the straight quick connector 10. The quick-release plate 9 is provided with anti-slip handles 904 at both ends. The straight quick connector 10 is provided with a magnetic sealing cap 1011.

[0029] In this example, it should be noted that by pulling or pushing the quick-release plate 9 towards the dividing plate 2 using the anti-slip handle 904, the quick-release plate 9 compresses the spring 902 and the valve head of the straight quick connector 10, allowing multiple air tubes 6 to be quickly detached from the dividing plate 2 without the need for the operator to disassemble individual air tubes 6, saving the operator time and bringing convenience to the operator.

[0030] See Figures 2 to 9 The slide module includes a slide 5 detachably connected to the frame 1. One end of the frame 1 is provided with a limit sleeve 103 and a step 104. One end of the slide 5 cooperates with the step 104. The other end of the slide 5 is provided with a limit block 502 that cooperates with the limit sleeve 103. Multiple locking parts 20 corresponding to the slide 5 are rotatably connected to the frame 1. A slide seat 501 is slidably connected to the slide 5. A multi-axis slide assembly 3 is connected to the slide seat 501. A rotary manipulator 4 is installed on the multi-axis slide assembly 3. A valve box 13 is provided on the multi-axis slide assembly 3. A solenoid valve and a flow meter are connected inside the valve box 13.

[0031] In this embodiment, it should be noted that: after the first mating head 401 adsorbs the magnetic sealing cap 1011 and detaches it from the straight quick connector 10, during the docking of the second mating head 402 with the straight quick connector 10, some external gas may be present in the straight quick connector 10 and the air pipe 6. Through the solenoid valve and flow meter, the air pump 11 extracts the soil gas in the air pipe 6 through the air extraction pipe 4021, and discharges some gas through the air outlet pipe 14 and the air injection head 16 before docking with the gas storage device 17 to perform the gas injection operation.

[0032] See Figures 4 to 5 and Figure 9The second mating head 402 is connected to the air extraction pipe 4021 and the air pump 11. The air pump 11 is connected to the solenoid valve by a connecting pipe 12. The air extraction pipe 4021 is correspondingly mated with the straight quick connector 10. The rotary manipulator 4 also includes a first mating head 401. The first mating head 401 is provided with an electromagnetic block 4011 corresponding to the magnetic sealing cover 1011.

[0033] In this embodiment, it should be noted that: the first mating head 401 adopts a compression tube design, with its head end and body slidably connected, and a return spring is provided between the two. The electromagnetic block 4011 is located at its head end. When the first mating head 401 descends and presses against the magnetic sealing cover 1011, the head end has a buffering effect and will not cause damage to the equipment. After the controller controls the electromagnetic block 4011 to be energized, it will adsorb the magnetic sealing cover 1011. After the gas sampling is completed, the rotating manipulator 4 will drive the first mating head 401 to reset the magnetic sealing cover 1011. After the reset, the electromagnetic block 4011 is de-energized and waits for the next energization adsorption operation. The head end of the second mating head 402 is provided with a sealing gasket, which presses against the straight quick connector 10, and the two are in a sealed connection, which facilitates the extraction of soil gas from the straight quick connector 10 and the air pipe 6 by the air extraction pipe 4021 inside the second mating head 402.

[0034] See Figures 8 to 12 and Figure 15 A turntable 8 is mounted on a slide table 5. A transmission belt 801 is rotatably connected to the turntable 8. A storage belt 802 is fitted onto the transmission belt 801. Multiple fixing sleeves 803 are evenly distributed on the storage belt 802. Multiple gas storage components 17 are detachably connected to the multiple fixing sleeves 803 respectively. A sensor 19 corresponding to the gas storage component 17 is provided on the slide table 5. A guide table 804 is provided on the turntable 8. A lift 15 is rotatably connected to the guide table 804. The lifting part of the lift 15 is provided with a fixing bracket 1501 connected to the gas injection head 16. A gas outlet pipe 14 is connected between the gas injection head 16 and the flow meter. A frustum 18 is provided on the guide table 804. A positioning seat 1801 is provided on the frustum 18. A positioning hole 1502 corresponding to the positioning seat 1801 is provided on the lift 15.

[0035] In this embodiment, it should be noted that: the base of the elevator 15 is rotatably connected to the guide platform 804 via the frustum 18. The positioning seat 1801 is provided with two mating holes. After the positioning hole 1502 on the base of the elevator 15 is engaged with one of the mating holes, the elevator 15 is in the working position, and its gas injection head 16 can be connected to the gas storage component 17. After the positioning hole 1502 is engaged with the other mating hole, the elevator 15 is in the standby position. Its base does not limit the storage belt 802 and the transmission belt 801, which facilitates the disassembly and assembly of the storage belt 802 on the transmission belt 801, so that the operator can install or store the gas storage component 17.

[0036] The working principle and usage process of this invention: The labeling plate 2 is provided with numerical labels corresponding to multiple straight quick connectors 10, which are arranged in an orderly manner from 1 to 30. The quick-release plate 9 is also provided with numerical labels from 1 to 30, which correspond to the numerical labels on the labeling plate 2. This setting makes it convenient for operators to quickly insert the probe 7 and air tube 6 from deep to shallow according to the corresponding numerical labels on the quick-release plate 9. The orderly arrangement of the labels on the labeling plate 2 eliminates the need for tedious manual edge application and reduces the probability of labeling errors. Multiple gas storage units 17 are respectively equipped with labels corresponding to the digital labels on the labeling plate 2. The transmission belt 801 drives the storage belt 802 to move. When the sensor 19 detects the label on the gas storage unit 17, it transmits the signal data to the controller. The controller controls the transmission belt 801 to stop moving and controls the multi-axis slide group 3 to drive the rotary manipulator 4 to move so that it is above the straight quick connector 10 corresponding to the gas storage unit 17. At this time, the rotary manipulator 4 rotates so that the first mating head 401 is aligned with the straight quick connector 10. The multi-axis slide group 3 drives the rotary manipulator 4 to descend. After the electromagnetic block 4011 on the first mating head 401 is energized, it contacts the magnetic sealing cover 1011 and attracts it. The multi-axis slide group 3 drives the first mating head 401 and its magnetic sealing cover 1011 to rise so that the straight quick connector 10 contacts the seal. After the rotary manipulator 4 rotates again to align the second mating head 402 with the straight quick connector 10, the multi-axis slide group 3 drives the second mating head 402 to descend so that it abuts against the straight quick connector 10 and connects with it. The air pump 11 draws soil gas from the air pipe 6 and probe 7 connected to the straight quick connector 10 through the air extraction pipe 4021, and transmits the drawn soil gas to the injection head 16 through the connecting pipe 12, valve box 13, and air outlet pipe 14. The lifting part of the elevator 15 drives the injection head 16 to descend so that it docks with the gas storage device 17 and injects soil gas. The elevator 15 then drives the injection head 16 to rise again, and the transmission belt 801 continues to run until the sensor 19 detects the gas storage device 17 again. This cycle is repeated. Once sensor 19 detects all gas storage units 17 on storage belt 802, the soil gas collection work of the sampling well is completed. The present invention facilitates quick matching and docking of gas tubes 6 with the markings on the label plate 2, replacing the tedious manual labeling operation, reducing the labeling error rate of gas tubes 6, and saving operators time in labeling and classifying gas tubes 6. The controller controls the gas collection component to automatically collect soil gas from multiple gas tubes 6 and probes 7, eliminating the need for manual docking and collection by operators, thus improving the efficiency of soil gas collection. The gas storage component automatically collects soil gas from the corresponding gas tubes 6 and probes 7, avoiding the situation of incorrect connection of gas tubes 6 or incorrect recording of label data due to manual docking of gas tubes 6 for gas collection.
