Description

Technical Field

[0001] This utility model belongs to the technical field of sampling and storage devices, and in particular relates to a gas sampling and storage device. Background Technology

[0002] Sampling and storing gases is essential because gases are fluid and volatile; their composition, concentration, and other properties change with environmental variations. Collecting target gases using specialized equipment and properly storing them ensures representative samples are obtained, preventing impurities from being introduced or component loss during collection. Furthermore, storage provides a stable environment for the gas during transportation and temporary storage, preventing reactions, leaks, or contamination. This ensures the sample remains in its original state throughout the entire process from collection to laboratory analysis, providing a reliable basis for subsequent component detection, pollution tracing, and process control. It is a crucial step in ensuring the accuracy of gas-related research, monitoring, and application results.

[0003] However, existing sampling and collection devices are not easy to prevent backflow of gas during the collection process, which can cause external gas to mix into the collected sample, destroy the representativeness and purity of the sample, and cause deviations in subsequent analysis results. Furthermore, backflow can also cause leakage of the collected gas, wasting the sample. Utility Model Content

A cross support bracket 212 is fixedly connected to the inner wall of the connecting pipe 211, and a ring 213 is fixedly connected to the inner wall of the connecting pipe 211. A piston 214 is installed inside the connecting pipe 211. The piston 214 and... The ring 213 is adapted to the cross support frame 212, which is equipped with an elastic element. The inner diameter of the ring 213 is the same as its diameter. The exhaust assembly 22 includes an exhaust pipe 221 threadedly connected to the outer wall of the connecting pipe 211. A cross support frame 222 is fixedly connected to the inner wall of the exhaust pipe 221, and an exhaust component is mounted on the cross support frame 222. The cross support frame 222 is installed at the central axis of the exhaust pipe 221, and the elastic element includes a component fixedly connected to the cross support frame 212. The telescopic rod 215 at the bottom of the support frame 212 is fixedly connected to the piston 214. A spring 216 is sleeved on the outer wall of the telescopic rod 215. The top of the spring 216 is fixedly connected to the cross support frame 212, and the bottom of the spring 216 is fixedly connected to the piston 214. The spring 216 has elasticity under normal conditions. The exhaust device includes a top rod 223 fixedly connected to the top of the cross support frame 222. The top of the top rod 223 is in contact with the piston 214. The top rod 223 is located at the central axis of the cross support frame 222. By setting the storage part 2, the ingress of external gas can be avoided, ensuring the representativeness and purity of the sample, making the subsequent analysis results more accurate, and preventing the leakage of collected gas, reducing sample waste. At the same time, with the cooperation of the piston 214, the telescopic rod 215 and the spring 216, the device automatically restores the sealed state after collection, ensuring the stable preservation of the collected gas and improving the reliability and efficiency of sampling and storage.

[0028] The sampling unit 3 includes a lifting assembly 31, which is mounted on the storage cylinder 111; and a sliding assembly 32, which is installed inside the storage cylinder 111. The sliding assembly 32 restricts the lifting assembly 31. The lifting assembly 31 includes a piston 311 slidably connected to the inner wall of the storage cylinder 111. A bracket 312 is fixedly connected to the top of the piston 311, and a threaded rod 313 is rotatably connected to the top of the bracket 312. The top of the threaded rod 313 extends outside the storage cylinder 111 and is threadedly connected to the storage cylinder 111. The threaded rod 313 is located at the central axis of the piston 311. The sliding assembly 32 includes several sliding rods 321 fixedly connected to the inner wall of the storage cylinder 111. Each sliding rod 321 passes through the piston 311 and is slidably connected to the piston 311. A handle 322 is fixedly connected to the top of the threaded rod 313. The handle 322 is located above the storage cylinder 111. By setting the sampling part 3 and turning the handle 322 to drive the structure to move together, the storage cylinder 111 can be quickly made to form a negative pressure and draw in gas to complete the sampling. At the same time, the components work together in an orderly manner to ensure that the gas enters the storage cylinder 111 smoothly, reduce the obstruction in the sampling process, and improve the sampling efficiency and stability.

[0029] A specific application of this embodiment is as follows: In use, first, the exhaust pipe 221 is turned off. Then, the device is moved to the position where sampling is required, and the handle 322 is turned to rotate the threaded rod 313. During this process, the piston 2 311 is restricted by the slide rod 321 and moves upward with the rotation of the threaded rod 313 through the connection of the bracket 312. At this time, the storage cylinder 111 is under negative pressure, and the piston 1 214 is pulled upward until the piston 1 214 disengages from the ring 213 and a gap is formed between the piston 1 214 and the ring 213. Gas is drawn into the storage cylinder 111 through this gap to complete the gas sampling. During the upward movement of the piston 1 214, the telescopic rod 215 and the spring 216 are compressed. When the spring 216 is compressed, it undergoes elastic deformation and stores elastic force. After the sampling is completed, the storage cylinder 111 is filled with the gas to be sampled, the negative pressure disappears, the spring 216 releases its elastic force and returns to the ring 213, so that the device returns to the sealed state.
