Description

Technical Field

[0001] This utility model relates to the field of environmental atmospheric sampling technology, specifically to an environmental atmospheric sampling sealing device. Background Technology

[0002] Atmospheric environmental protection is of great significance. It is committed to reducing the emission of air pollutants, mitigating the harm of smog and acid rain, protecting human respiratory health, reducing the incidence of respiratory diseases, and maintaining atmospheric balance to ensure climate stability and prevent damage to agriculture and ecology caused by frequent extreme weather. A good atmospheric environment can also enhance the city's image, promote tourism development, drive sustainable economic growth, and achieve harmonious coexistence between humans and nature. Environmentally friendly atmospheric sampling and sealing devices are important tools for collecting atmospheric environmental samples. With their precise design, they can efficiently collect atmospheric samples from different altitudes and regions, covering gases, particulate matter, and other pollutants.

[0003] However, traditional environmentally friendly atmospheric sampling and sealing devices cannot easily carry sample air. During the carrying process, air is lost due to accidental contact with the pull tube, and the air cannot be completely sealed during the exhaust process. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an environmentally friendly atmospheric sampling and sealing device that allows operators to extract air from the area to be tested anytime and anywhere while carrying it with them, and provides a better sealed and independent storage environment for the extracted air during inhalation and exhalation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly atmospheric sampling and sealing device, comprising a storage chamber, an electric telescopic rod, and a sealing plug. One end of the storage chamber is fitted with the sealing plug, and one end of the sealing plug is fixed with a first exhaust port. A second exhaust port is fixed to the outside of the sealing plug and is sleeved with the first exhaust port. One end of the first exhaust port is fixed with a supporting slide rod, and a limit plate is fixed to the middle of the supporting slide rod. A baffle is fixed to the end of the supporting slide rod away from the first exhaust port. A second sealing baffle is slidably arranged on the outside of the supporting slide rod and abuts against the outer end face of the second exhaust port.

[0006] By adopting the above technical solution, the sealing plug is used to provide a sealing function for one end of the storage compartment, the first exhaust port is used to exhaust the air stored inside the storage compartment, the second exhaust port is used to collect the air exhausted from the first exhaust port and exhaust it, the supporting slide rod is used to provide a limiting sliding function for the second sealing baffle, the limiting plate is used to provide a limiting function for the second sealing baffle, and the second sealing baffle and the second exhaust port can be opened and closed, so that the second exhaust port can exhaust air more conveniently.

[0007] Furthermore, a connecting part is fixed at one end of the storage compartment, and a driving part is fixed at the other end of the connecting part.

[0008] By adopting the above technical solution, the storage chamber is used to store external air samples, the connecting part is used to connect the storage chamber and the drive part to form an integrated structure, and the drive part is used to provide installation function for the electric telescopic pole.

[0009] Furthermore, the drive unit is equipped with an electric telescopic rod, which is electrically connected to the control center, and the output end of the electric telescopic rod is equipped with a rubber sealing ring.

[0010] By adopting the above technical solution, which involves installing an electric telescopic rod inside the drive unit and electrically connecting it to the control center, the operation is automated and precisely controlled. The output end of the electric telescopic rod is equipped with a rubber sealing ring, which moves under the drive of the electric telescopic rod, allowing for flexible changes in the size of the storage compartment and thus precise control of the air pressure inside the storage compartment.

[0011] Furthermore, the storage compartment has a groove-shaped structure inside for the rubber sealing ring to slide, and slides in contact with the rubber sealing ring.

[0012] By adopting the above technical solution, a groove-shaped structure is opened inside the storage compartment for the rubber sealing ring to slide, and slides in close contact with the rubber sealing ring. The groove-shaped structure provides a precise sliding track for the rubber sealing ring, so that the rubber sealing ring can slide stably along a predetermined path under the drive of the electric telescopic rod. The close contact and sliding between the rubber sealing ring and the groove-shaped structure enhances the sealing performance of the storage compartment.

[0013] Furthermore, air inlets are provided on both sides of one end of the storage compartment, and a first sealing baffle is rotatably mounted inside the air inlet via a torque shaft.

[0014] By adopting the above technical solution, air inlets are opened on both sides of one end of the storage chamber, and a first sealing baffle is set inside the air inlet by a torsion shaft. The dual air inlets increase the air intake area, so that when collecting atmospheric samples, outside air can enter the storage chamber more quickly and smoothly through the air inlets, which improves the efficiency of sample collection and shortens the collection time.

[0015] Furthermore, a spring is sleeved on the outer side of the support slide rod, and it abuts against the second sealing baffle and the baffle plate respectively. The cross-section of the second sealing baffle is set with an inclined structure.

[0016] By adopting the above technical solution, which uses a spring sleeved on the outside of the support slide rod and abuts against the second sealing baffle and the baffle plate respectively, the spring provides elastic support and restoring force to the second sealing baffle.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model, by setting an air inlet and a first sealing baffle, reduces the pressure inside the storage chamber when the rubber sealing ring retracts inside the storage chamber via the electric telescopic rod, thereby allowing outside air to push the first sealing baffle and enter the storage chamber through the air inlet. When the rubber sealing ring stops moving, the first sealing baffle will be reset via the torsion shaft, thereby sealing and closing with the air inlet.

[0019] 2. This utility model, by setting a second exhaust port, a second sealing baffle, and a spring, allows the first sealing baffle to enhance the seal with the air inlet by compressing the air inside the storage chamber when the rubber sealing ring moves. At this time, the air inside the storage chamber is discharged through the first exhaust port to the interior of the second exhaust port, and the pressure pushes the second sealing baffle so that it can slide on the outside of the support slide rod. During the sliding process, the second sealing baffle will disengage from the second exhaust port, thereby allowing the air inside the storage chamber to be discharged. After the air inside the storage chamber is discharged, the spring will provide elastic retraction to the second sealing baffle, so that the second sealing baffle will close with the second exhaust port again.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment:

[0027] An environmentally friendly atmospheric sampling and sealing device, such as Figures 1-4 As shown, it includes a storage compartment 1, an electric telescopic rod 4, and a sealing plug 8. One end of the storage compartment 1 is snapped with the sealing plug 8, and one end of the sealing plug 8 is fixed with a first exhaust port 9. A second exhaust port 10 is fixed to the outside of the sealing plug 8 and is sleeved with the first exhaust port 9. One end of the first exhaust port 9 is fixed with a support slide rod 11, and a limit plate 12 is fixed in the middle of the support slide rod 11. A baffle 13 is fixed to the end of the support slide rod 11 away from the first exhaust port 9. A second sealing baffle 14 is slidably arranged on the outside of the support slide rod 11 and abuts against the outer end face of the second exhaust port 10.

[0028] The storage chamber 1 is connected to a sealing plug 8 at one end. The sealing plug 8 is provided with a first exhaust port 9 and a second exhaust port 10, which are nested together. This structural design ensures good overall sealing of the device, effectively preventing the sample from being contaminated by the outside world during storage and transportation, and ensuring the purity of the sample. A support slide rod 11 is provided at the first exhaust port 9. A limiting plate 12 and a baffle 13 are fixed on the support slide rod 11 to provide stable support and limit the sliding of the second sealing baffle 14, ensuring that the second sealing baffle 14 is accurately positioned during the sliding process and can accurately abut or separate from the second exhaust port 10, ensuring stable and reliable sealing and exhaust operations when air is discharged.

[0029] See Figure 1 and Figure 2 One end of the storage compartment 1 is fixed with a connecting part 2, and the other end of the connecting part 2 is fixed with a driving part 3;

[0030] The technical solution of fixing the connecting part 2 at one end of the storage compartment 1 and fixing the driving part 3 at the other end of the connecting part 2 provides a good transition and connection, making the connection between the storage compartment 1 and the driving part 3 more stable and tight, and enhancing the structural stability of the entire device.

[0031] See Figure 2 The drive unit 3 is equipped with an electric telescopic rod 4, which is electrically connected to the control center. The output end of the electric telescopic rod 4 is equipped with a rubber sealing ring 5.

[0032] The operator only needs to issue a command through the control center, and the electric telescopic rod 4 can move accurately according to the preset parameters without the need for frequent manual adjustments, which greatly improves the efficiency and convenience of operation and reduces the errors that may be caused by human operation. When collecting samples, the rubber sealing ring 5 is used to reduce the air pressure in the storage chamber 1, allowing outside air to enter smoothly; when discharging samples, the air pressure can be changed to discharge the air.

[0033] See Figure 2 The storage compartment 1 has a groove-shaped structure inside for the rubber sealing ring 5 to slide, and slides in contact with the rubber sealing ring 5.

[0034] During the movement of the rubber sealing ring 5, it can always maintain a good fit with the groove structure, effectively preventing air leakage from the gap between the rubber sealing ring 5 and the inner wall of the storage chamber 1, ensuring the airtightness of the sample during storage and transportation, and further improving the quality of the sample and the practicality of the device.

[0035] See Figure 1 and Figure 2 The storage compartment 1 has air inlets 6 on both sides of one end, and the air inlets 6 have a first sealing baffle 7 that rotates through a torsion shaft inside.

[0036] The first sealing baffle 7 is rotatably mounted inside the air inlet 6 via a torque shaft. When the rubber sealing ring 5 stops moving, the first sealing baffle 7 can automatically reset via the torque shaft and tightly close with the air inlet 6.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A spring 15 is sleeved on the outside of the support slide rod 11 and abuts against the second sealing baffle 14 and the baffle 13 respectively. The cross section of the second sealing baffle 14 is set with a sloping structure.

[0038] When air is expelled from storage chamber 1, the second sealing baffle 14 slides on the support slide rod 11 under the pressure of air, separating from the second exhaust port 10 to achieve exhaust; after exhaust is completed, the elastic recoil force of the spring 15 can quickly reset the second sealing baffle 14, and re-press tightly against the second exhaust port 10 to ensure the airtightness of storage chamber 1 and effectively prevent outside air from entering and contaminating the sample.

[0039] The implementation principle of this embodiment is as follows: First, an operator holds the drive unit 3 and simultaneously activates the electric telescopic rod 4 inside the drive unit 3 via the control center. The electric telescopic rod 4 drives the rubber sealing ring 5 to move inside the storage chamber 1. When the rubber sealing ring 5 moves to one side of the drive unit 3, it reduces the air pressure inside the storage chamber 1, allowing outside air to push the first sealing baffle 7 and enter the storage chamber 1 through the air inlet 6. When the rubber sealing ring 5 stops moving, the first sealing baffle 7 is reset via the torque shaft, thus sealing and closing with the air inlet 6. The operator can then seal and carry the sample from the storage chamber 1. When it is necessary to expel the air sample from inside the storage chamber 1, the drive unit 3 can move the rubber sealing ring 5 away from the drive unit 3. When the first sealing baffle 7 moves, it strengthens the seal with the air inlet 6 through pressure. At this time, the air inside the storage chamber 1 is discharged into the second exhaust port 10 through the first exhaust port 9, and pushes the second sealing baffle 14 with pressure, causing the second sealing baffle 14 to slide on the outside of the support slide rod 11. Then, during the sliding process, the second sealing baffle 14 will disengage from the second exhaust port 10, thereby allowing the air inside the storage chamber 1 to be discharged. Finally, after the air inside the storage chamber 1 is discharged, the spring 15 will provide elastic retraction to the second sealing baffle 14, allowing the second sealing baffle 14 to close with the second exhaust port 10 again. At the same time as the second sealing baffle 14 closes with the second exhaust port 10, the limiting plate 12 will provide a limiting and tightening effect on the second sealing baffle 14.
