Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to an atmospheric deposition sample collection device. Background Technology

[0002] In environmental monitoring, the collection of atmospheric deposition samples is an essential task. When conducting atmospheric deposition sampling, it is often necessary to collect samples from different altitudes at the same location and bring them back to the laboratory for analysis.

[0003] A search revealed that patent application CN111678746A discloses an automated atmospheric sedimentation sample collection device with freely controllable altitude. The device includes a collection box containing a collection tube. The handle of the collection box is connected to a balloon via a thin rope. The bottom of the collection box is fixedly connected to one end of a graduated vertical line, the other end of which is wound around a spool. The collection tube includes a cap and a tube body threadedly connected to the cap. The device uses a balloon to lift the collection box into the air. The altitude of the collection box is determined by the centimeter-precise graduations on the vertical line. When the set altitude is reached, pressing a remote control de-energizes the first electromagnet and energizes the second electromagnet. A lightweight rubber stopper falls under the combined force of magnetism and gravity, adhering to the tube wall and expelling the air from the tube body through a hole at the bottom. The atmospheric sedimentation sample at the designated altitude enters the tube body through the plastic tube, achieving automatic sealing after collection.

[0004] While the device can collect gas at different altitudes during use, it can only collect once at a time, and only at one altitude. Furthermore, it needs to be continuously launched to a suitable altitude, which is inconvenient for gas collection and reduces the collection speed. To address these issues, we propose an atmospheric sedimentation sample collection device. Utility Model Content

[0005] This invention provides an atmospheric deposition sample collection device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An atmospheric deposition sample collection device includes a collection box, a balloon that lifts the collection box, a vertical line for controlling the height of the collection box, a spool for controlling the length of the vertical line, and a bracket for fixing the spool. A detachable collection box cover is installed on the upper end of the collection box, and an interlocking upper electromagnet and a lower electromagnet are installed inside the collection box below the collection box cover.

[0008] The bottom of the upper electromagnet is provided with a rubber stopper that can move up and down. The middle of the rubber stopper is provided with a permanent magnet that can communicate with the upper electromagnet and the lower electromagnet. The permanent magnet is driven to move by the magnetic force between the upper electromagnet and the lower electromagnet and its own gravity. A slider is fixedly connected to the inner circumference of the rubber stopper.

[0009] The rubber plug is installed on the outer circumference of the positioning post. A closed-loop groove is provided on the outer circumference of the positioning post. The slider can move within the groove trajectory to drive the rubber plug to rotate while moving up and down.

[0010] Inside the collection box, below the rubber stopper, are multiple collection bottles. An inner collection tube runs through the rubber stopper directly above each collection bottle. When the rubber stopper moves down, the inner collection tube can be inserted into the collection bottle to pump gas into it. When the rubber stopper moves up, it rotates simultaneously, causing the inner collection tube to move to the top of another collection bottle.

[0011] Preferably, the collection box is provided with a detachable collection inner box, and a rubber plug is installed inside the collection inner box and fits tightly against the side wall of the collection inner box.

[0012] Preferably, an installation plate is installed at the bottom of the inner collection box, the collection bottle is located on top of the installation plate, and multiple clamping posts are installed on the top of the installation plate to define the position of the collection bottle.

[0013] Preferably, the collection bottle is equipped with a one-way valve that controls the unidirectional flow of gas into the collection bottle, and a rubber sheet that fits tightly against the inner wall of the collection bottle is installed below the one-way valve inside the collection bottle.

[0014] Preferably, when the inner collecting tube enters the collecting bottle, the one-way valve can be pushed open and gas can be injected into the collecting bottle. At this time, the gas pushes the rubber sheet downward.

[0015] Preferably, a spring is installed at the bottom of the rubber sheet, so that when the gas in the collection bottle is removed, the spring returns to its original shape and can lift the rubber sheet upward.

[0016] Preferably, the bottom of the collection bottle has a round hole, so that when the rubber sheet moves down, the air at the bottom of the rubber sheet will be discharged through the round hole.

[0017] Preferably, the one-way valve includes a valve cover, a valve body, and a torsion spring. The valve cover is connected to the valve body via a pin to open and close the valve body. The torsion spring is connected to the pin to drive the valve cover to close.

[0018] This utility model has the following beneficial effects:

[0019] 1. This atmospheric deposition sample collection device uses a slider on a rubber stopper to move within a groove on a positioning column, which restricts the rubber stopper and the inner collection tube passing through the rubber stopper to rotate and move up and down simultaneously. When the rubber stopper moves downward, the inner collection tube can be inserted into the bottom collection bottle and filled with the gas to be collected. When the rubber stopper moves upward, the inner collection tube will rotate and move upward to the top of another collection bottle, ready for a new round of collection.

[0020] 2. This atmospheric sedimentation sample collection device, by having a one-way valve and a rubber sheet in the collection bottle, allows the gas in the one-way valve and rubber sheet to be retained under normal conditions. The round hole at the bottom of the collection bottle allows the rubber sheet to move downwards while collecting gas, ensuring consistent gas pressure inside the bottle. A spring is installed at the bottom of the rubber sheet, which can reset the rubber sheet when the collected gas in the rubber sheet and one-way valve is released for detection, facilitating gas discharge.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 An atmospheric deposition sample collection device includes a collection box 1, a balloon 3 that lifts the collection box 1, a vertical line 4 for controlling the height of the collection box 1 and a spool 5 for controlling the length of the vertical line 4, a bracket 6 for fixing the spool 5, a detachable collection box cover 2 installed on the upper end of the collection box 1, and an interlocking upper electromagnet 7 and lower electromagnet 17 installed under the collection box cover 2; the balloon 3 can lift the collection box 1 upward, and the placement length of the vertical line 4 can be controlled by rotating the spool 5, thereby controlling the accurate height of the collection box 1;

[0030] The upper electromagnet 7 has a rubber plug 9 that can move up and down at its bottom. The middle of the rubber plug 9 has a permanent magnet that can communicate with the upper electromagnet 7 and the lower electromagnet 17. The permanent magnet is driven to move by the magnetic force between the upper electromagnet 7 and the lower electromagnet 17 and its own gravity. A slider 21 is fixedly connected to the inner circumference of the rubber plug 9. When the upper electromagnet 7 is energized, the lower electromagnet 17 will be de-energized and fail. At this time, the rubber plug 9 will be attracted to move upward along with the slider 21. When the lower electromagnet 17 is energized, the upper electromagnet 7 fails. At this time, the rubber plug 9 and the slider 21 move downward under the attraction of gravity and the lower electromagnet 17.

[0031] The rubber plug 9 is installed on the outer circumference of the positioning post 10. A sliding groove 20 is provided on the outer circumference of the positioning post 10. The slider 21 can move within the track of the sliding groove 20, causing the rubber plug 9 to rotate while moving up and down. The track of the sliding groove 20 is connected, allowing the rubber plug 9 to rotate and move continuously on the positioning post 10. When the rubber plug 9 moves down, it causes the slider 21 to move vertically downward. When the rubber plug 9 moves up, it causes the slider 21 to move up, and at the same time, the slider 21 causes the rubber plug 9 to rotate.

[0032] Inside the collection box 1, below the rubber stopper 9, are multiple collection bottles 12. An inner collection tube 11 is connected to the rubber stopper 9 directly above the collection bottle 12. When the rubber stopper 9 moves down, the inner collection tube 11 can be inserted into the collection bottle 12 to pump gas into the collection bottle 12. When the rubber stopper 9 moves up, the rubber stopper 9 rotates at the same time, which moves the inner collection tube 11 to the top of another collection bottle 12 to prepare for a new round of collection. The sliding groove 20 on the positioning column 10 ensures that the inner collection tube 11 reaches the top of the collection bottle 12 each time.

[0033] Please see Figures 1 to 2 The collection box 1 is equipped with a detachable inner collection box 8. A rubber stopper 9 is installed inside the inner collection box 8 and fits tightly with it. An air pump (not shown in the figure) is provided in the collection tube 203. The air pump can draw outside gas into the space between the collection box cover 2 and the rubber stopper 9. The pumped gas can enter the collection bottle 12 through the inner collection tube 11.

[0034] Please see Figures 1 to 2 The bottom of the inner collection box 8 is equipped with an installation plate 18, and the collection bottle 12 is located on the top of the installation plate 18. Multiple clamping posts 16 are installed above the installation plate 18 to limit the position of the collection bottle 12. The inner side of the two clamping posts 16 is in close contact with the outer side of the collection bottle 12. The friction between them prevents the collection bottle 12 from moving or shaking easily. After collection is completed, the collection bottle 12 can be removed from between the clamping posts 16.

[0035] Please see Figures 2 to 6 The collection bottle 12 is equipped with a one-way valve 13 that controls the one-way flow of gas into the collection bottle 12. Below the one-way valve 13, there is a rubber sheet 15 that fits tightly against the inner wall of the collection bottle 12. The one-way valve 13 only opens into the collection bottle 12. Under normal conditions, the one-way valve 13 is tightly closed to prevent gas leakage from the bottle.

[0036] Please see Figures 2 to 6 When the inner collecting tube 11 enters the collecting bottle 12, it can push the one-way valve 13 inward and inject gas into the collecting bottle 12. At this time, the gas pushes the rubber sheet 15 downward. After the injection is completed, the one-way valve 13 closes. At this time, the gas between the one-way valve 13 and the rubber sheet 15 is the gas to be detected.

[0037] Please see Figures 2 to 6 A spring 14 is installed at the bottom of the rubber sheet 15. When the gas in the collection bottle 12 is removed, the spring 14 returns to its original state and can push the rubber sheet 15 upward, so that the rubber sheet 15 returns to its original position and promotes the discharge of gas from the rubber sheet 15 and the one-way valve 13.

[0038] Please see Figures 2 to 5 The bottom of the collection bottle 12 has a round hole 22. When the rubber sheet 15 moves down, the air at the bottom of the rubber sheet 15 will be discharged through the round hole 22, so that the internal air pressure of the collection bottle 12 remains consistent, making it easier to collect gas.

[0039] Please see Figures 2 to 6The one-way valve 13 includes a valve cover 23, a valve body, and a torsion spring. The valve cover 23 is connected to the valve body via a pin to open and close the valve body. The torsion spring is connected to the pin to drive the valve cover to close. When the inner collecting tube 11 extends into the collecting bottle 12 or collects the gas, the valve cover 23 can be rotated inward by the pin to open. After the inner collecting tube 11 is removed or the collection is completed, the valve cover is rotated by the pin under the action of the torsion spring to tightly fit the valve body, so that the gas in the one-way valve 13 and the rubber sheet 15 cannot pass through the valve cover 23, thus retaining the gas.

[0040] In summary, this atmospheric sedimentation sample collection device, during use, moves the slider 21 on the rubber stopper 9 within the groove 20 on the positioning column 10, causing the rubber stopper 9 and the inner collection tube 11 connected to the rubber stopper 9 to rotate and move up and down simultaneously. When the rubber stopper 9 moves down, it causes the inner collection tube 11 to move vertically downwards. At this time, the inner collection tube 11 will be inserted into the collection bottle 12 located directly below it. At this time, the suction pump (not shown in the figure) in the collection tube 203 will draw outside gas into the space between the collection box cover 2 and the rubber stopper 9. The inner collection tube 11 first opens the one-way valve 13, and at the same time, the rubber stopper 9... The gas enters the collection bottle 12 through the inner collection tube 11. The gas pushes the rubber sheet 15 downward. The bottom of the collection bottle 12 has a round hole 22, through which air at the bottom of the rubber sheet 15 can be discharged, keeping the pressure of the rubber sheet 15 consistent and making it easier to store gas. When the rubber stopper 9 moves upward, it will drive the inner collection tube 11 to rotate and move upward. After reaching the top, the inner collection tube 11 will reach the top of another collection bottle 12, ready for a new round of collection. When the gas is taken out of the collection bottle 12, the spring 14 at the bottom of the rubber sheet 15 will lift the rubber sheet 15 to facilitate the next round of collection.
