AI Technical Summary
Technical Problem
Existing deep water sampling equipment cannot avoid mixing of surface water and target deep water during the sinking process, resulting in inaccurate test results, and the sample is easily replaced during the recovery process.
Method used
It adopts a telescopic or foldable telescopic sleeve structure, and the contraction and expansion of the telescopic sleeve are controlled by a pull rod to realize the emptying and sampling of deep water areas. Combined with the rotation locking mechanism of the pull rod and the top cover, it ensures the sealing during the recovery process.
Benefits of technology
It enables precise collection of target deep water samples, avoids contamination by upper water layers, and ensures sample integrity and accuracy of test results.

Abstract
This invention relates to the field of water sampling technology, specifically to a deep water sampling device and method for detecting pollution in drinking water sources in the field. The device includes a cylindrical sampler comprising a telescopic sleeve, a pull rod, a top cover, and a drain nozzle. The telescopic sleeve is a telescopic or foldable cylindrical structure. The bottom end of the pull rod is horizontally rotatably connected to the bottom of the sampler. The pull rod passes through the middle of the top cover and has a stop block; a locking opening is provided in the middle of the top cover. This invention, by setting up a telescopic sleeve structure that can actively drain and suck in water, achieves precise collection of target deep water samples. By setting up a rotational locking mechanism between the pull rod and the top cover, a reliable seal is achieved at the top opening of the sampler, thus fundamentally preventing the mixing of upper layer water and ensuring the singularity and accuracy of the sample source.
