Description

Technical Field

[0001] This utility model relates to the field of data collection devices, and in particular to an atmospheric treatment gas collection device. Background Technology

[0002] Air pollution occurs when substances enter the atmosphere due to human activities or natural processes, reaching sufficient concentrations and persisting for a sufficient period, thereby harming human comfort, health, and welfare, or the environment. Air pollutants enter the atmosphere from anthropogenic or natural sources, participate in atmospheric circulation, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities, and physical sedimentation. If the rate of output is less than the rate of input, substances will relatively accumulate in the atmosphere, causing an increase in the concentration of certain substances. When the concentration rises to a certain level, it will directly or indirectly cause acute or chronic harm to humans, organisms, or materials; thus, the atmosphere is polluted.

[0003] In existing technologies, when controlling air pollution, it is necessary to detect and analyze pollution sources. This requires the use of sampling devices to collect gas from the pollution source. The information from the collected gas samples is then used to detect the pollution source and its concentration. Existing gas sampling devices typically extract air directly from the atmosphere and bring it to the laboratory for testing. However, since it is not possible to collect gas from other locations during the sampling process, and the storage tanks cannot differentiate between gases collected from other locations, the laboratory test data becomes inaccurate.

[0039] 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.

[0040] This utility model provides, for example Figure 1-6 An atmospheric gas collection device is shown, comprising: a base plate 1, a door panel rotatably connected to the front of the base plate 1, a protective box connected to the upper surface of the base plate 1, a rotating platform 2 rotatably mounted on the top of the base plate 1, multiple limiting cylinders 3 connected in a circular array on the rotating platform 2, a storage device 4 disposed inside the limiting cylinders 3, and an extraction device connected inside the protective box; the extraction device includes: an air pump 6, which is fixedly installed inside the protective box; a connecting device 7, which is installed inside the protective box and connected to the air pump 6; the storage device 4 is connected to the air pump 6 through the connecting device 7; the rotation of the rotating platform 2 facilitates the rotation of the limiting cylinders 3, causing the limiting cylinders 3 to rotate and adjust the storage device 4 inside, so that it moves directly below the connecting device 7; the storage device 4 facilitates the storage of extracted gas; the positioning mechanism 5 facilitates the positioning of the rotating platform 2; and the operation of the air pump 6 facilitates the extraction of gas from the storage device 4, so that atmospheric air can be drawn in.

[0041] Specifically, the storage device 4 includes: a collection cylinder 41, which is movably fitted inside the limiting cylinder 3; and one-way mechanisms 42, which are respectively connected to both sides of the top of the collection cylinder 41, and the connection directions of the one-way mechanisms 42 are opposite, so that gas can enter on one side and exit on the other through the two one-way mechanisms 42, so as to draw atmospheric air into the interior of the collection cylinder 41 for storage, and the one-way mechanisms 42 can prevent gas leakage. The one-way mechanism 42 includes: a connecting seat 421, which is connected to and communicates with the top of the collection cylinder 41; and a one-way component, which is movably installed inside the connecting seat 421. The one-way component includes: a fixing plate 422, which is fixedly installed inside the connecting seat 421, and has a vent hole; a first spring 423, which is disposed inside the connecting seat 421 and is in a compressed state; a sealing head 424, one end of the first spring 423 is connected to the fixing plate 422, and the other end of the first spring 423 is connected to the sealing head 424, which is used for one-way sealing of the inner cavity of the connecting seat 421; and a guide rod 425, which is disposed inside the first spring 423, and one end of the guide rod 425 is connected to the sealing head 424. The plug 424 is fixedly connected, and the other end of the guide rod 425 is slidably inserted into the fixing plate 422. The connecting seat 421 facilitates the fitting of the pipe 72 to achieve the connection between the pipes. The fixing plate 422 facilitates the limiting of the sliding insertion of the guide rod 425, making the linear movement of the plug 424 more stable. The mutual cooperation between the plug 424 and the opening of the connecting seat 421 facilitates unidirectional sealing of the opening of the connecting seat 421. The compression deformation of the first spring 423 facilitates the elastic support of the plug 424, so as to allow unidirectional gas flow in the connecting seat 421.

[0042] Furthermore, a positioning mechanism 5 is connected to the front of the rotating platform 2. The positioning mechanism 5 includes: ear plates 51, multiple ear plates 51 are connected to the outer wall of the rotating platform 2 in a circular array, and the ear plates 51 correspond to the positions of the limiting cylinder 3; a fixed frame 52, which is fixedly installed on the upper surface of the base plate 1; and a positioning pin 53, which is inserted between the fixed frame 52 and the ear plates 51. The positioning pin 53 simultaneously inserts the ear plates 51 and the fixed frame 52 to facilitate the positioning of the ear plates 51, which in turn facilitates the positioning of the rotating platform 2 after rotation, thereby making the fit between the storage device 4 and the connecting device 7 more accurate.

[0043] Furthermore, the connecting device 7 includes: a mounting plate 71, which is horizontally positioned; a mating pipe 72, which is fixedly inserted and connected to both sides of the mounting plate 71, and is sleeved with the one-way mechanism 42. A corrugated pipe is connected to the top of the mating pipe 72, one of which is connected to the air inlet of the air pump 6, and the other is connected to an air inlet hopper, which is fixedly inserted and connected to the protective box; a connecting rod 73, one end of which is connected to a connecting post, one end of which is fixedly connected to the mounting plate 71, and the connecting rod 73 is slidably inserted and connected to the top of the protective box; and a second spring 74, which is movably sleeved on the outer wall of the connecting rod 73. Since the connecting device 7 is located directly above one of the storage devices 4, when gas needs to be extracted through the storage device 4, the storage device 4 is rotated to be directly below the connecting device 7. By releasing the external force applied to the connecting rod 73, and through the elastic support of the second spring 74, the mating pipe 72 and the one-way mechanism 42 cooperate with each other. Then, by operating the vacuum pump 6, external gas can be drawn into the collection cylinder 41 through the bellows and one-way mechanism 42, thus collecting the gas. By rotating the rotary table 2, different storage devices 4 can be moved to the bottom of the connecting device 7 for extraction, so as to distinguish and store the gas collected from other places, improving the accuracy of laboratory test data. The connecting rod 73 facilitates the control of the movement of the mounting plate 71, and the compression deformation of the second spring 74 facilitates the elastic support of the connecting column, which in turn facilitates the elastic support of the mounting plate 71, making the sleeve fit between the mating pipe 72 and the one-way mechanism 42 more stable. The expansion and contraction of the bellows facilitates the up and down movement of the mating pipe 72. The two mating pipes 72 are respectively sleeved with the two one-way mechanisms 42 to form a loop for atmospheric extraction, so that the atmosphere enters the collection cylinder 41 from the air inlet hopper, and the gas in the inner cavity of the collection cylinder 41 is extracted and discharged by the vacuum pump 6, thus realizing the extraction of the atmosphere.
