Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically a gas collection device for environmental monitoring. Background Technology

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. Environmental monitoring determines the level of environmental pollution and environmental quality by monitoring and measuring indicators that reflect environmental quality. In environmental monitoring, air collection is necessary to better understand the types and concentrations of air pollutants, assess environmental quality, and provide data support for scientific research.

[0003] Currently available gas collection devices typically draw gas into a collection device, which then fills the gas storage cylinder.

[0004] If continuous gas sampling is desired, the gas in the storage cylinder must first be emptied, and the repeated operation takes a long time, thus affecting the collection efficiency of environmental monitoring gas samples.

[0005] Therefore, we propose to design a gas collection device for environmental monitoring. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides a gas collection device for environmental monitoring, including a collection box 1, a handle 2 fixedly connected to the bottom of the collection box 1, and a sliding rod 3 slidably connected to one side of the outer wall of the collection box 1.

[0025] In this embodiment, a finger hole 5 is provided at the center of the outer end of the slide rod 3. The width of the finger hole 5 is twelve centimeters, which makes it convenient for the staff to pull the slide rod 3 to drive the piston 6 to collect gas.

[0026] The slide bar 3 passes through the inside of the collection box 1 and is fixedly connected to the piston 6. The inner wall of the collection box 1 away from the slide bar 3 is fixedly connected to the mounting bracket 7, and the mounting bracket 7 has a through hole 8 inside.

[0027] There are two through holes 8, which are located on both sides of the mounting frame 7. The bottom of the sealing plate 9 passes through the mounting frame 7 and is located between the two through holes 8. By inserting the sealing plate 9 into the two corresponding through holes 8, it is easy to separate the collection box 1 from the gas storage cylinder 10.

[0028] A sealing plate 9 is provided on the top of the collection box 1, and a first one-way valve 4 is fixedly connected to both sides of the end of the collection box 1 near the mounting frame 7. The first one-way valve 4 is connected to the inside of the collection box 1, and the connection hole between the first one-way valve 4 and the collection box 1 is located between the piston 6 and the mounting frame 7. When the piston 6 is pulled, a negative pressure is generated in the collection box 1, and air is then introduced through the first one-way valve 4, which facilitates the collection of gas in the environment.

[0029] A gas storage cylinder 10 is provided at the end of the collection box 1 away from the slide bar 3. Several gas storage cylinders 10 are provided and are evenly distributed on the outer wall of the collection box 1. The arrangement of multiple gas storage cylinders 10 makes it easy to collect multiple sets of gas at the same time and quickly, without the need to frequently disassemble and replace the gas storage cylinders 10.

[0030] A second one-way valve 11 is installed at the mouth of the gas storage cylinder 10.

[0031] In this embodiment, an inner connecting ring 111 and an outer connecting ring 112 are fixedly connected to both ends of the second one-way valve 11, respectively. A connecting pipe connected to the through hole 8 is fixedly connected to the outer wall of the collection box 1. The inner connecting ring 111 is threaded to the connecting pipe, and the outer connecting ring 112 is threaded to the mouth of the gas storage cylinder 10. When replacing the gas storage cylinder 10, after sealing the through hole 8 with the sealing plate 9, the second one-way valve 11 and the gas storage cylinder 10 can be removed together by directly turning the inner connecting ring 111. This not only ensures the sealing of the collection box 1 and facilitates the continued collection of gas, but also keeps the gas storage cylinder 10 sealed, making it easy to move it to the detection equipment and release the gas.

[0032] When in use, the staff holds the handle 2 to carry the collection box 1. In the initial state, the piston 6 is located at one end close to the mounting frame 7.

[0033] When collecting gas, the operator pulls the slide bar 3 to move the piston 6 in the collection box 1. As the piston 6 moves, a negative pressure is generated in the collection box 1, which allows the gas from the external environment to enter the collection box 1 through the first one-way valve 4.

[0034] During bottling, pull up the sealing plate 9 corresponding to any empty gas storage bottle 10 to connect the two through holes 8 on both sides of the sealing plate 9. At this time, pushing the slide rod 3 can drive the piston 6 to slide, squeezing the gas from the through hole 8 into the gas storage bottle 10, and collecting it in the gas storage bottle 10 through the second one-way valve 11.

[0035] After the bottle is filled, the sealing plate 9 is reinserted into the mounting bracket 7, and the sealing plate 9 at the corresponding position of the other empty gas cylinder 10 is removed. By repeating the above steps, gas can be injected into other gas cylinders 10 respectively, thereby quickly obtaining multiple sets of gas samples.

[0036] When disassembling and replacing the gas cylinder 10, insert the sealing plate 9 completely into the mounting bracket 7, and then remove the inner connecting ring 111 together with the second one-way valve 11 and its corresponding gas cylinder 10 from the outside of the collection box 1 to obtain a complete gas sample.

[0037] At this time, the gas cylinder 10 can remain sealed. When needed, the outer connecting ring 112 on the outside of the gas cylinder 10 can be unscrewed to release the gas sample, thus ensuring the integrity of the sample.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
