Description

Technical Field

[0001] The utility model specifically relates to a sampling device for water conservancy detection, belonging to the technical field of water conservancy detection. Background Technique

[0002] Before the implementation of a water conservancy project, it is necessary to detect the water quality of each layer of water body, such as detecting the water turbidity, sediment content, sediment ratio, and water body pollution degree of each layer of water body; when detecting water quality, it is necessary to sample the water body. For existing sampling devices, such as a sampling device for water conservancy detection disclosed in Chinese Patent Publication No.: CN221826527U, when sampling and detecting water sources at different depths, the sampling mechanism is placed in the water source through a retracting and releasing mechanism. The sampling box at the bottom of the sampling mechanism will take the lead in sampling the water source of the uppermost layer. After sampling, it will sink downward by its own gravity, and then drive the multiple sampling boxes above to sink one by one to sample water sources at different depths. When sampling, a filter screen is used to filter impurities contained in the water source. However, when sampling the water source with the above structure, when the sampling mechanism enters the water source area, it will cause oscillation in the surrounding area of the water source. When the water source is not in balance, the sampling of the water source is completed, and the collected water sample cannot accurately represent the actual water sample index of this layer of water body.
