Description

Technical Field

[0001] This utility model relates to the field of forestry wetland technology, specifically to a wetland monitoring water sample collection device. Background Technology

[0002] In forestry wetland ecosystem monitoring, water sampling is fundamental to the analysis of water quality parameters. It is necessary to construct artificial or natural wetlands to purify water quality and restore fragile habitats. Artificial wetlands are controllable wetland systems built by humans to simulate the structure and function of natural wetland systems. They are a technology used to treat polluted water. Wetlands have a powerful ecological purification function. Studying the pollutant reduction effect and the degree of ecological restoration of different forms of artificial or natural wetlands is of great significance to ecological construction.

[0003] The existing wetland water sampling method mainly involves sampling buckets. The sampling buckets take out the water samples and then transfer them into sample bottles. Then, the sampling buckets are used to take samples again. Since the sampling buckets can only take water samples from one depth at a time, multiple samplings are required at the same sampling point. This requires transferring the samples in the sampling buckets into new sample bottles one by one, which is a complicated and inefficient process. Utility Model Content
