On each section of the telescopic rod 3, there is a detachable sampling tube guide ring 32 for supporting and guiding the sampling tube 2 to prevent the sampling tube 2 from sagging due to the weight of the water inside during the sampling process.

[0033] On the rechargeable hand-held driving body 1, there is a sampling bottle holder for placing the sampling bottle, which facilitates the insertion of the sampling tube into the sampling bottle for water sample extraction.

[0034] A water quality sampling device for portable environmental detection of the utility model. When in use, one end of the sampling tube can be tied with a lead weight first, and then the sampling tube is passed through the guiding ring of the telescopic fishing rod. A anti-bending guiding groove is fixed at the front end of the fishing rod. Finally, the fishing rod is fixed on the telescopic rod fixing clip of the lithium battery pistol drill, a peristaltic pump head is installed, the sampling tube is clamped on the peristaltic pump head, a sampling bottle is placed in the sampling bottle rack, and the sampling tube is inserted into the sampling bottle. According to the sampling requirement, the end of the sampling tube with the lead weight is sent to the sampling location and placed at the sampling depth in the water as needed. Press the switch of the lithium battery pistol drill to extract the water sample until the sampling bottle is filled with the water sample. Then, the sampling of the next sample is carried out.

[0035] A water quality sampling device for portable environmental detection of the utility model does not require the sampling bottle to be forcefully picked over during the sampling process, does not require the sampler to have great arm strength, and has strong usability.

[0036] A water quality sampling device for portable environmental detection of the utility model can also replace the sampling tube once for each water sample collection as needed during use, which can ensure that the collected water sample is not contaminated.

[0037] A water quality sampling device for portable environmental detection of the utility model can be used not only for field water body sampling but also for sampling some liquids.

[0038] The above uses specific examples to elaborate on the utility model, which is only used to help understand the utility model and does not limit the utility model.
