Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the environment detection gas sampling device of this embodiment includes a base 1, a gas collecting tank 2, an air pump 3, a sampling bottle 4 and a pushing mechanism 5, wherein a moving wheel is arranged at the bottom of the base 1, a handrail is further arranged at one side of the base 1, and the sampling device can be pushed to move conveniently through the arrangement of the handrail and the moving wheel to sample in different places.
The gas collecting tank 2 is arranged on the base 1, the air pump 3 is arranged on one side of the gas collecting tank 2, the sampling bottle 4 is arranged on one side of the gas collecting tank 2 adjacent to the air pump 3, the air pump 3 and the sampling bottle 4 are communicated with the inside of the gas collecting tank 2, and the air pump 3 pumps external gas into the gas collecting tank 2 and enters the sampling bottle 4.
The pushing mechanism 5 is arranged below the sampling bottle 4 and is in transmission connection with the sampling bottle 4, and the movement of the sampling bottle 4 can be realized through the pushing mechanism 5, so that the automatic sampling is realized.
As shown in FIG. 2, a filter screen 6 is arranged in the gas collecting tank 2, and the filter screen 6 can be made of coarse-effect filter materials such as filter cotton and non-woven fabrics, so that large-particle impurities in gas can be removed, and meanwhile, the influence on gas components is avoided.
As shown in fig. 3, a sampling port 8 is arranged at a position corresponding to the sampling bottle 4 on the side surface of the gas collecting tank 2, a sealing ring 9 is arranged on the outer side of the sampling port 8, and a sampling tube 10 is arranged on the inner side of the sampling port 8.
