Description

Technical Field

[0001] This utility model relates to a sampler, and more particularly to an automatic sampler for air pollutants. Background Technology

[0002] Automatic air pollutant samplers (AAPS) are devices used to automatically collect samples of pollutants in the atmosphere, and are widely used in environmental monitoring, scientific research, and other fields. The working principle of AAPS is mainly based on physical adsorption, filtration, or absorption methods to collect pollutants from the air. Among these, the absorption method involves guiding air through an absorption bottle or tube containing specific chemical reagents. These chemical reagents react with the target pollutants, capturing them from the air. Depending on the application scenario and requirements, samplers have the following drawbacks when used outdoors:

[0003] 1. Traditional samplers lack effective sunshade measures and are easily affected by direct sunlight. When sampling in high-temperature environments, the internal temperature rises, which not only affects the performance and lifespan of electronic components but may even lead to equipment malfunction. Furthermore, temperature fluctuations can affect the accuracy and reliability of sampling, especially under extreme weather conditions.

[0004] 2. Traditional samplers have a relatively simple structure and usually lack sufficient storage space. Operators need to carry additional boxes to store sample containers, spare filter membranes, chemical reagents, etc., increasing the complexity and inconvenience of operation. Improper storage of samples and reagents can easily lead to confusion and loss, affecting work efficiency and data accuracy. Utility Model Content

[0005] To overcome the aforementioned shortcomings, the technical problem is to provide an automatic sampler for air pollutants.

[0006] The technical solution is as follows: An automatic air pollutant sampler includes a tripod, a worktable, a flip cover, an air pump, a delivery pipe, an outlet pipe, a lifting frame, a guide rod, a return spring, a cup body, a support frame, a rotating cylinder, a torsion spring, a sunshade cloth, a controller, and a drive assembly. The worktable is connected to the top of the tripod. A flip cover is rotatably connected to the top left side of the worktable. An upper compartment is located on the upper left side of the worktable, and an air pump is installed in the upper compartment. The air pump has a three-way structure, and both ends of the air pump are connected to delivery pipes. A lower compartment is located on the lower left side of the worktable, and a guide rod is connected to the bottom of the lower compartment. A lifting frame is slidably connected to the guide rod. The lifting frame... A return spring connects the lower compartments, and the return spring is sleeved on the guide rod. The lifting frame is slidably connected to the lower compartment. Cups are symmetrically attached to the lifting frame. The lower end of the conveying pipe is connected to the lower compartment and is inserted into the corresponding cup. An L-shaped air outlet is symmetrically connected to the left side of the worktable. The lower end of the air outlet is connected to the lower compartment and extends into the cup, while the upper end passes through the left wall of the worktable. A support frame is connected to the upper rear side of the worktable. A rotating cylinder is rotatably connected to the upper side of the support frame. A sunshade cloth is wound on the rotating cylinder. Torsion springs are connected between both ends of the rotating cylinder and the support frame. A drive assembly is provided on the worktable, and a controller is installed on the front side of the top of the worktable.

[0007] Furthermore, the sunshade fabric is made of polyethylene.

[0008] Furthermore, the drive assembly includes a connecting frame, a guide frame, a motor, and a rotating frame. The guide frame is slidably connected to the top right side of the worktable, and the connecting frame is connected to the upper side of the guide frame. The connecting frame is connected to one end of the sunshade cloth. The motor is installed on the left side of the support frame and is electrically connected to the controller. The rotating frame is connected to the output shaft of the motor, and the right end of the rotating frame is slidably connected to the connecting frame.

[0009] Furthermore, it also includes a placement frame, which is slidably connected to the front side of the worktable.

[0010] Furthermore, the placement frame has four slots for placing the cup.

[0011] Furthermore, it also includes solar panels and batteries. The solar panels and batteries are installed on the top right side of the workbench, with the solar panels located to the right of the batteries. Both the solar panels and batteries are electrically connected to the controller, and the batteries supply power to the motor and air pump.

[0012] The beneficial effects are: 1. By using a motor as a power source, the sunshade cloth is automatically unfolded and placed above the sampler, which can effectively block direct sunlight and prevent the internal temperature of the sampler from becoming too high, thereby maintaining the stability of the internal environment of the equipment and ensuring the accuracy and reliability of sampling.

[0013] 2. The placement frame provides storage space for convenient storage of sample containers, reducing inconvenience during on-site operations and ensuring the safety of samples and reagents, preventing accidental leakage or damage.

[0014] 3. Solar panels provide a continuous power supply, making them especially suitable for remote areas or long-term field operations, eliminating the need to rely on external power sources and increasing the flexibility and applicability of the equipment. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example: An automatic air pollutant sampler, such as Figures 1-3As shown, the system includes a tripod 1, a workbench 2, a flip-top 3, an air pump 4, a delivery pipe 5, an air outlet pipe 6, a lifting frame 7, a guide rod 8, a return spring 9, a cup body 10, a support frame 11, a rotating cylinder 12, a torsion spring 13, a sunshade 14, a controller 20, and a drive assembly. The top of the tripod 1 is connected to the workbench 2. The flip-top 3 is rotatably connected to the top left side of the workbench 2. An upper compartment is located on the upper left side of the workbench 2. An air pump 4 for drawing air is bolted into the upper compartment. The air pump 4 has a three-way structure, with delivery pipes 5 connected to both ends. The top of the air pump 4 is used to connect to an external pipe for gas transmission. A lower compartment is located on the lower left side of the workbench 2. A guide rod 8 is welded to the bottom of the lower compartment. A lifting frame 7 is slidably connected to the guide rod 8. A return spring 9 connects the lifting frame 7 to the lower compartment. Force spring 9 and return spring 9 are sleeved on guide rod 8. Lifting frame 7 is slidably connected to lower compartment. Cup body 10 is symmetrically snapped onto lifting frame 7. The lower end of conveying pipe 5 is connected to lower compartment and inserted into corresponding cup body 10. L-shaped air outlet pipe 6 is symmetrically connected to the left side of worktable 2. The lower end of air outlet pipe 6 is connected to lower compartment and extends into cup body 10, while the upper end penetrates the left wall of worktable 2. Support frame 11 is connected to the upper rear side of worktable 2. Rotating cylinder 12 is rotatably connected to the upper side of support frame 11. Sunshade cloth 14 is wound on rotating cylinder 12. Sunshade cloth 14 is made of polyethylene, which is both heat resistant and waterproof. Torsion spring 13 is connected between the left and right ends of rotating cylinder 12 and support frame 11. Drive assembly is provided on worktable 2. Controller 20 is installed on the front top of worktable 2.

[0022] like Figure 1 and Figure 3 As shown, the drive assembly includes a connecting frame 15, a guide frame 16, a motor 17, and a rotating frame 18. The guide frame 16 is slidably connected to the top right side of the worktable 2. The connecting frame 15 is welded to the upper side of the guide frame 16. The connecting frame 15 is connected to one end of the sunshade cloth 14. The motor 17 is bolted to the left side of the support frame 11. The motor 17 is electrically connected to the controller 20. The rotating frame 18 is connected to the output shaft of the motor 17. The right end of the rotating frame 18 is slidably connected to the connecting frame 15.

[0023] like Figure 1 and Figure 4 As shown, it also includes a placement frame 19. The placement frame 19 is slidably connected to the front side of the workbench 2. The placement frame 19 has four slots for placing the cup 10.

[0024] like Figure 1As shown, it also includes a solar panel 21 and a battery 22. The solar panel 21 and the battery 22 are installed on the top right side of the workbench 2. The solar panel 21 can absorb sunlight and convert sunlight into electrical energy. The solar panel 21 is located to the right of the battery 22. Both the solar panel 21 and the battery 22 are electrically connected to the controller 20. The battery 22 supplies power to the motor 17 and the air pump 4.

[0025] When using this device to sample air pollutants, first support the device at the target point using tripod 1, then open the flip cover 3, insert the external connecting pipe into the top port of the air pump 4, and then pull the lifting frame 7 downwards along the guide rod 8. The return spring 9 will compress accordingly, and the cup 10 containing the chemical reagent will be placed on the front and rear sides of the lifting frame 7. Then slowly release the lifting frame 7, and the return spring 9 will rebound and reset. The lifting frame 7 will move upwards with the cup 10 and reset. The lower ends of the delivery pipe 5 and the outlet pipe 6 are both inserted into the cup 10. The lower end of the delivery pipe 5 is in direct contact with the liquid in the cup 10, while the lower end of the outlet pipe 6 is in contact with the liquid due to its height. If the air level is too high and not in contact with the target pollutant, start the air pump 4. The air pump 4 delivers air, which is then introduced into the cup 10 through the delivery pipe 5. The chemical reagent reacts with the target pollutant and captures it from the air. The clean air after absorption is discharged from the outlet pipe 6. After sampling is completed, turn off the air pump 4 and repeat the above operation to pull the lifting frame 7 down to lower the height, making it easier to take out the cup 10 and seal it. The placement frame 19 can be pulled forward and the sealed cup 10 can be placed in the slot of the placement frame 19 for temporary storage. After placement, push the placement frame 19 backward into the workbench 2. In hot weather, to prevent the internal temperature of the workbench 2 from becoming too high and affecting the normal operation of electronic components and the sampling of contaminants, motor 17 can be started. The output shaft of motor 17 rotates, driving the rotating frame 18 to rotate. The right end of the rotating frame 18 pushes the connecting frame 15 and the guide frame 16 to move linearly forward along the workbench 2, thus stretching the sunshade 14. The sunshade 14 then drives the rotating cylinder 12 to rotate, causing the torsion spring 13 to deform and pull the sunshade 14 out to shield the device from strong light, effectively preventing the device from overheating. Once in the appropriate position, simply turn off motor 17. Similarly, in rainy weather, the sunshade 14 can be used as a waterproof cloth to block rainwater and prevent it from directly washing over the device and affecting air extraction. When it is necessary to retract the sunshade 14, control motor 17 to rotate in reverse. Its output shaft drives the rotating frame 18 to rotate in reverse, thereby moving the connecting frame 15 and the guide frame 16 to the rear, thus releasing the sunshade 14. The torsion spring 13 then rebounds and resets, driving the rotating cylinder 12 to rotate in reverse and retract the sunshade 14. After resetting, motor 17 automatically turns off. In daily use, when the sunlight is not particularly strong, sunlight shines on the solar panel 21, which converts sunlight into electrical energy. This energy is then transmitted to the battery 22 via controller 20. The battery 22 can power motor 17 and air pump 4, playing an environmentally friendly role. When the battery 22 is depleted, motor 17 and air pump 4 can still be powered through other channels.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
