Description
Technical Field
[0001] This utility model belongs to the field of gas sampling technology, specifically an environmental monitoring gas sampling device. Background Technology
[0002] Environmental monitoring gas sampling refers to the collection of gas samples of a certain volume or mass from ambient air using specific equipment and methods, so as to facilitate subsequent analysis and measurement of pollutant components and concentrations in the gas, thereby enabling the monitoring and assessment of ambient air quality and providing a scientific basis for environmental management and decision-making.
[0003] For example, CN219996653U discloses an environmental monitoring gas sampling device, which includes a sampling cylinder, a sampling head, and a partition cover. The sampling head is located at the bottom of the sampling cylinder, and the partition cover is fitted onto the sampling head. A filter layer is provided inside the sampling cylinder. A pull rod is slidably fitted into a through hole on the top wall of the sampling cylinder. A piston is fixedly connected to the lower end of the pull rod, and the piston is slidably and sealingly connected to the inner wall of the sampling cylinder. A sleeve plate is slidably fitted onto the upper end of the pull rod. A limit part is provided at the top of the pull rod to prevent the sleeve plate from sliding out of the upper end of the pull rod. A fixing structure is provided on the sleeve plate to fix the pull rod. This utility model has good stability in the sealed space and is not easily affected by external forces, which could lead to gas leakage.
[0004] However, in practical use, it was found that environmental monitoring operations generally require extracting gases from the environment and bringing them back to the laboratory for sampling and analysis. This gas extraction needs to be quantitative to facilitate subsequent analysis. Traditional extraction methods include syringe extraction and gas sampling bag collection. However, these methods are prone to errors in the amount of gas extracted during operation. Therefore, to ensure a stable amount of gas extracted across multiple extractions, a mechanical device is needed to assist in limiting the extracted gas, thereby reducing operational errors during multiple extractions. Utility Model Content
[0005] The purpose of this invention is to provide an environmental monitoring gas sampling device in order to solve the problem of the mechanical device mentioned above providing an auxiliary restriction for gas extraction, thereby reducing operational errors in multiple extraction processes.
[0006] The technical solution adopted by this utility model is as follows: an environmental monitoring gas sampling device, wherein a sliding plate is slidably inserted into the inner side surface of the suction gun body, a suction rod is slidably inserted into the side surface of the sliding plate, a piston is fixedly connected to the side surface of the suction rod, a U-shaped connecting shaft is fixedly connected to the side surface of the sliding plate, a positioning rod is fixedly connected to one end of the U-shaped connecting shaft relative to the side surface of the sliding plate, a capacity adjustment clamp is fixedly connected to the side surface of the suction gun body, a plurality of capacity limiting holes are opened on the side surface of the capacity adjustment clamp, a capacity positioning bolt is inserted into the capacity limiting holes through the opened holes, and a suction handle is fixedly connected to one end of the suction rod relative to the piston.
[0007] By adopting the above technical solution, the operator uses the suction gun body as the main structural component for suction. The sliding plate, U-shaped connecting shaft, positioning rod, capacity adjustment clamp, capacity limiting hole, and capacity positioning bolt on the gun serve as the quantitative positioning components. After setting the desired suction volume, the operator manually moves the suction rod, piston, and suction handle to achieve suction. The positioning components ensure that the suction volume is maintained quantitatively after suction. Through these components, the operator can fix the suction volume without using sensors, thus minimizing operational errors during multiple suctions. The entire structure is simple to use and easy to maintain.
[0008] The suction gun body, serving as the main suction structure, is hollow inside.

As it slides on the capacity adjusting clamp, when it reaches a certain position, it uses the capacity limiting hole on the clamp as a corresponding reference component. Once the two coincide, a capacity positioning bolt connects them, thus fixing the capacity extraction. The positions of the capacity limiting holes correspond to different capacity sizes, making the entire structure not only simple but also offering a degree of adjustment flexibility.

[0013] By adopting the above technical solution, an air extraction pipe is used as the air extraction pipeline, and an external connector fixedly connected to its side surface serves as a connecting component. Protective components are connected to it to prevent external debris from entering the pipeline.
[0014] In a preferred embodiment, a protective mesh is threadedly connected to the inner side surface of one end of the external connector relative to the suction pipe, and multiple guide plates are fixedly connected to the upper surface of the transition cavity.
[0015] By adopting the above technical solution, a protective net is used as a protective net, and its densely spaced mesh plays a protective role. A guide plate is used as a connecting component to connect the corresponding components.
[0016] In a preferred embodiment, the guide plate is slidably inserted with a sealing insert through an opening slot.
[0017] By adopting the above technical solution, the sealing plug is used as a sliding plug baffle component. Its downward sliding blocks the transition cavity, thus achieving gas preservation after gas extraction.
[0018] In a preferred embodiment, a plurality of plug-in screws are fixedly inserted into the side surface of the sealing plug.
[0019] By adopting the above technical solution, the sliding of the plug screw on the slide groove is used to achieve the positioning of the sealing plug plate.
[0020] In a preferred embodiment, the insertion screw is rotatably inserted into a positioning nut on one end side surface of the sealing plate.
[0021] By adopting the above technical solution, the positioning nut and the plug screw interact and tighten, thereby increasing the contact friction between the positioning nut and the edge of the slide groove and thus achieving final fixation.
[0022] In a preferred embodiment, a hand handle is fixedly connected to the bottom surface of the vacuum gun body.
[0023] By adopting the above technical solution, a handheld handle is used as a convenient part for operators to hold when extracting gas. The handheld handle facilitates the gas extraction operation for the operator.

A sliding plate on its inner side surface serves as a positioning component, primarily functioning to limit and block suction. A suction rod is slidably inserted into the sliding plate.
