Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring and sampling, specifically, it relates to an atmospheric environmental monitoring and sampling device that can store multiple samples. Background Technology

[0002] Atmospheric environmental monitoring sampling devices are a type of specialized equipment used to collect environmental media or parameters such as gaseous pollutants, particulate matter, and volatile organic compounds (VOCs) in the atmosphere. Their core function is to obtain representative atmospheric samples through standardized sampling methods.

[0003] Chinese Patent CN222212394U discloses an atmospheric environment monitoring sampling device, comprising: a first electrically controlled valve and a second electrically controlled valve respectively connected to a sampling pipe and a purified air pipe; a gas guide channel located on one side of the gas distribution box between the sampling pipe and the extraction pipe; and a gas filter connected on one side of the gas distribution box between the purified air pipe and the extraction pipe. This application effectively solves the problem of pipeline cleaning after operation by connecting a gas filter between the purified air pipe and the extraction pipe. However, when using a gas filter, it must be replaced regularly because impurities accumulate inside the filter, which may reduce filtration efficiency and, in severe cases, even affect the thoroughness of pipeline cleaning or contaminate the sampled air, thus affecting the accuracy of subsequent detection data.

Detailed Implementation

[0041] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Please see Figure 1-4 As shown, this embodiment provides an atmospheric environment monitoring sampling device capable of storing multiple samples, including:

[0043] The box 1 has two hinged doors 103 at the side opening, and an air quality detector 2 is installed on the upper side of the box 1. The box 1 is equipped with a dual-inlet air extraction mechanism 4 and a bracket 11; the output end of the dual-inlet air extraction mechanism 4 is equipped with a dispensing and storage mechanism 3.

[0044] A dual-outlet air intake mechanism 6 is installed on the upper part of the housing 1, and an air guide pipe 7 is installed between the dual-outlet air intake mechanism 6 and the dual-inlet air extraction mechanism 4.

[0045] The gas filter 10 is sandwiched between the dual-outlet air intake mechanism 6 and the dual-inlet air extraction mechanism 4. The filter element of the gas filter 10 is made of polytetrafluoroethylene (PTFE) with a porosity of 85% to 90%.

[0046] The lifting mechanism 9 is used to push the ends of the dual-inlet suction mechanism 4 upward; and

[0047] The compression box 12 is elastically fitted to the upper part of the support 11. The top of the compression box 12 is provided with an inclined groove 1201 for the compression lifting mechanism 9 to rise. The compression box 12 is elastically fitted with a lifting plate 13. Multiple trapezoidal blocks 1301 are linearly arrayed on the upper side of the lifting plate 13. The height of the multiple trapezoidal blocks 1301 increases sequentially. The height difference between adjacent trapezoidal blocks 1301 is 2 to 5 mm. The inclination angle of the trapezoidal blocks 1301 is 30° to 45° to balance the thrust and self-locking effect. The top of the trapezoidal blocks 1301 is located in the inclined groove 1201.

[0048] One application of this embodiment is as follows: First, the lifting plate 13 is pulled down, causing all trapezoidal blocks 1301 to descend synchronously, thereby retracting the top of the trapezoidal blocks 1301 located in the inclined groove 1201; at this time, the squeezing box 12 slides back to its original position under the action of elastic force, canceling the squeezing restriction on the lifting mechanism 9, allowing the lifting mechanism 9 to slide freely under the action of gravity, releasing the clamping and fixing of the dual-inlet air extraction mechanism 4 on the gas filter 10, thereby realizing the replacement of the gas filter 10. After the gas filter 10 is replaced, the compression box 12 is pushed horizontally on the bracket 11 by external force. The bottom wall of the inclined groove 1201 squeezes the lifting mechanism 9 to make it rise, forcing the lifting mechanism 9 to push the end of the dual-inlet suction mechanism 4 upward together, so that the dual-inlet suction mechanism 4 and the dual-outlet intake mechanism 6 can clamp the gas filter 10 together. During the movement of the compression box 12, the lifting mechanism 9 squeezes the inclined surface of the trapezoidal stop 1301 in the opposite direction, making it slide down. After the trapezoidal stop 1301 passes the lifting mechanism 9, the elastic force makes the trapezoidal stop 1301 and the lifting plate 13 return to their original positions, and the vertical surface of the trapezoidal stop 1301 abuts against the vertical surface of the lifting mechanism 9 to prevent the compression box 12 from sliding in the opposite direction. This process is repeated to make the lifting mechanism 9 rise in stages. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0049] By cooperating with multiple trapezoidal stops 1301, the lifting plate 13 can be pulled down to simultaneously retract all trapezoidal stops 1301, releasing the reset restriction on the squeezing box 12 and quickly releasing the clamping force of the lifting mechanism 9 on the gas filter 10. When pushing the squeezing box 12 to move, the inclined groove 1201 is used to squeeze the lifting mechanism 9 to rise. At the same time, the trapezoidal stops 1301 with progressively increasing heights achieve the staged lifting and self-locking of the lifting mechanism 9, improving the reliability of the gas filter 10 clamping and fixing and the smoothness of the replacement operation, reducing errors or time costs caused by complex operation, and reducing the impact on cleaning efficiency and effect.

[0050] like Figure 1As shown, the dispensing and storage mechanism 3 of this embodiment includes a main pipe 301 embedded in the upper part of one side of the housing 1. Multiple first solenoid valves 303 are linearly arrayed at the bottom of the main pipe 301. A storage tank 304 is installed below the first solenoid valves 303, and a second solenoid valve 305 is installed on the inner wall side of the storage tank 304. Optionally, a third solenoid valve 302 is installed at the end of the main pipe 301. The response time of the first solenoid valve 303, the second solenoid valve 305, and the third solenoid valve 302 is ≤0.5 seconds, and the leakage rate is ≤0.1%, ensuring sampling accuracy through rapid response. Optionally, a base plate 104 is installed at the lower part of one side of the housing 1. The second solenoid valve 305 is located above the base plate 104. A base plate 104 is installed on top of the base plate 104, and the upper part of the base plate 104 is installed around the main pipe 301. The base plate 104 is located between the first solenoid valve 303 and the third solenoid valve 302. When the air quality detector 2 detects an anomaly, the abnormal air is drawn into the designated storage tank 304 by opening the first solenoid valve 303. Then, the first solenoid valve 303 is closed and the third solenoid valve 302 is opened to deliver the purified air to the main air purification pipe 301. Repeating the above steps allows for sampling of abnormal air from multiple time periods. Finally, the sample is removed by opening the second solenoid valve 305, and the purified air is then used to clean the storage tank 304. The use of multiple first solenoid valves 303 and corresponding storage tanks 304 and second solenoid valves 305 facilitates time-sharing and channel-based storage of a single extraction of gas, improving the independent storage capacity of multiple samples and reducing the risk of cross-contamination.

[0051] like Figure 2 As shown, the dual-inlet suction mechanism 4 of this embodiment includes a suction pump 401 installed on the lower side of the inner wall of the housing 1. The output end of the suction pump 401 is equipped with an air supply pipe 402, and the input end is equipped with a suction pipe 403. The end of the air supply pipe 402 is installed at the end of the main pipe 301 away from the third solenoid valve 302, and the air supply pipe 402 is connected to the main pipe 301. The end of the suction pipe 403 is equipped with a lower three-way valve 404. The first input end of the lower three-way valve 404 is equipped with a first connecting pipe 405, which is a flexible hose. The end of the first connecting pipe 405 is equipped with a movable seat 406. The dual-inlet design of the suction pump 401 and the lower three-way valve 404 facilitates flexible switching of the air source; the use of a flexible hose for the first connecting pipe 405 reduces the impact of the first connecting pipe 405 on the lifting and lowering displacement of the movable seat 406.

[0052] like Figure 3As shown, the lifting mechanism 9 in this embodiment includes a circular plate 901. Multiple extension rods 902 are installed between the circular plate 901 and the lower end face of the movable seat 406. A trapezoidal push block 903 is provided on the lower end face of the circular plate 901. The vertical cross-section of both the trapezoidal push block 903 and the trapezoidal stop block 1301 is a right-angled trapezoidal structure. The inclined surface of the trapezoidal push block 903 is tightly fitted to the bottom of the inclined groove 1201. The circular plate 901 is connected to the movable seat 406 via the extension rods 902 and cooperates with the trapezoidal push block 903, facilitating the conversion of the horizontal sliding of the compression box 12 into the vertical displacement of the movable seat 406.

[0053] like Figure 2 As shown, the dual-inlet air intake mechanism 6 of this embodiment includes an upper three-way valve 602 located inside the housing 1. An air intake pipe 601 is installed at the input end of the upper three-way valve 602. The lower part of the air intake pipe 601 is embedded in the top of the housing 1. A second connecting pipe 603 is installed at the first output end of the upper three-way valve 602. A fixing seat 604 is installed at the end of the second connecting pipe 603. An air guide pipe 7 is installed between the second output end of the upper three-way valve 602 and the second input end of the lower three-way valve 404. Optionally, both the movable seat 406 and the fixed seat 604 are annular structures. The upper end face of the movable seat 406 and the lower end face of the fixed seat 604 are provided with slots. A sealing ring is embedded in the slot. The end of the gas filter 10 is engaged in the corresponding slot, and the gas filter 10 is squeezed to achieve a seal by using clamping force. The clamping force of the movable seat 406 and the fixed seat 604 on the gas filter 10 is 5 to 15 N, which reduces the risk of poor sealing and damage to the gas filter 10 due to insufficient clamping force. The sealing ring is made of nitrile rubber with a Shore hardness of 60±5 and a compression amount of 20% to 30% of the original thickness, ensuring sealing performance while avoiding permanent deformation. During sampling, the upper three-way valve 602 is controlled to connect the air inlet pipe 601 to the air guide pipe 7, and the lower three-way valve 404 is controlled to connect the suction pipe 403 to the air guide pipe 7. During cleaning, the upper three-way valve 602 is controlled to connect the air inlet pipe 601 to the second connecting pipe 603, and the lower three-way valve 404 is controlled to connect the suction pipe 403 to the first connecting pipe 405. The sealing ring and the slot cooperate to facilitate end-face sealing by squeezing the sealing ring when clamping the gas filter 10, improving the airtightness of the filter connection and reducing the risk of gas leakage.

[0054] like Figure 2 , 4As shown, in this embodiment, a support plate 101 is installed between the upper and lower sides of the inner wall of the housing 1. A fixed seat 604 is installed on the upper part of one side of the support plate 101, and a movable seat 406 is slidably fitted in the middle of one side of the support plate 101. Optionally, a T-shaped groove 102 is provided on one side of the support plate 101, and T-shaped blocks are slidably fitted in the T-shaped groove 102 on the sides of both the movable seat 406 and the circular plate 901. The transverse cross-section of the T-shaped groove 102 and the T-shaped blocks are both T-shaped structures. By cooperating with the T-shaped groove 102 and the T-shaped blocks, the movement trajectory of the movable seat 406 is easily constrained, the stability of the lifting mechanism 9 during the pushing process is improved, and the risk of sealing failure caused by positional deviation is reduced.

[0055] like Figure 3 , 4 As shown, the bracket 11 in this embodiment includes a rectangular frame 1101. The middle part of the extrusion box 12 is slidably fitted within the rectangular frame 1101. Lifting plates 1103 are installed between both ends of the rectangular frame 1101 and the lower side of the inner wall of the box body 1. Optionally, both sides of the inner wall of the rectangular frame 1101 are provided with sliding grooves 1102, and both sides of the extrusion box 12 are provided with guide strips 1204 that are slidably fitted within the sliding grooves 1102. Optionally, a guide rod 1205 is provided on one side of the extrusion box 12, and a limiting block 1206 is installed at the end of the guide rod 1205. The guide rod 1205 passes laterally through one of the lifting plates 1103, and a first spring 1207 is installed between the extrusion box 12 and the lifting plate 1103. The first spring 1207 is located around the guide rod 1205. The cooperation between the slide groove 1102 and the guide bar 1204, along with the reset design of the first spring 1207, facilitates the smoothness of the sliding of the compression box 12, enhances the fluency of operation, and reduces the burden of manual reset.

[0056] like Figure 3 As shown, a handle 8 is provided below the extrusion box 12 in this embodiment, and pull rods 801 are installed between both ends of the handle 8 and the lower side of the lifting plate 13. Optionally, the extrusion box 12 is provided with a movable cavity 1202, and multiple vertical grooves 1203 are provided between the movable cavity 1202 and the inclined groove 1201 to connect the two. Trapezoidal blocks 1301 pass through the vertical grooves 1203, the lifting plate 13 is slidably fitted in the movable cavity 1202, and the upper part of the pull rods 801 passes through the movable cavity 1202; wherein, two second springs 802 are installed between the lifting plate 13 and the lower side of the movable cavity 1202, and the second springs 802 are located on the periphery of the pull rods 801. The second springs 802 reduce the time cost of resetting the trapezoidal blocks 1301 one by one; the vertical grooves 1203 improve the stability of the trapezoidal blocks 1301 sliding up and down.
