Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a convenient sampling device for environmental monitoring. Background Technology

[0002] Water quality monitoring is a unified, timed or continuous monitoring of the quality and quantity of water, as well as various anthropogenic and natural factors affecting the ecological and environmental quality of water bodies, in accordance with the water cycle. Especially when monitoring river water, sampling devices are typically used to collect samples, which are then brought back to the laboratory for data analysis. River water sampling usually involves tying a rope to a sampling container, holding one end of the rope, and throwing the container into the river. Once the container is full of water, it is pulled back to the riverbank; the operation is simple.

[0003] However, in actual operation, since the sampling container is usually an open container, it will collide with the riverbank during the process of pulling it back to the riverbank, which can easily cause the water in the container to spill out. If the sample capacity is insufficient, multiple samplings are required. Moreover, if the container is directly thrown into the river, it is necessary to wait for the river water to slowly enter the container before it can sink into the water. Therefore, it takes a certain amount of time for the container to fill with water, which significantly reduces the convenience of sampling. Therefore, this application proposes a portable sampling device for environmental monitoring that can quickly sample and prevent water spillage. Utility Model Content
