Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an environmental monitoring sample storage tube. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality status. Environmental monitoring is to determine the environmental pollution status and the level of environmental quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators and ecosystems. It is the basis for scientific management of the environment and environmental law enforcement supervision, and is an indispensable basic work for environmental protection.

[0003] According to the search, Chinese patent literature, announcement number: CN216233885U, discloses an environmental monitoring sample storage tube, which is disassembled and connected through a funnel and a water stop assembly through a connection unit 2, and the disassembly connection is through a threaded connection, so as to facilitate the sample to be taken out of the tube body through the water inlet and the disassembly of the funnel connected to the floating block. The floating block is provided with a boss on which the sample enters the tube body through the funnel to push the floating block upward to fit with the seal, thereby sealing the water inlet and effectively preventing the tube cover from falling off during transportation and causing the sample to splash out. However, during use, when it is necessary to take out the sample, the funnel connected to the floating block is disassembled to facilitate the sample to be taken out of the tube body, which makes sampling troublesome and time-consuming. At the same time, during use, the sample needs to completely fill the sample storage tube before the funnel and the seal can be fitted and sealed, resulting in the internal pressure being easily increased under the influence of temperature during transportation, resulting in accidents during sampling, and the safety of use is low.
