Abstract

The invention discloses a device and a method for collecting a deep self-filtration sealing water sample, and relates to the technical field of environment protection and water resource monitoring. The device comprises a bottom counterweight water inlet module (10), a self-filtration sealing module (20), a lower hollow connecting module (31), a water storage cabin (40), an upper hollow connecting module (32), a water-passing sealing cover module (50), a prolonge conical head module (60) and an inflexible scale digging rope (70) which are sequentially connected from bottom to top. According to the device disclosed by the invention, a high-quality water sample which is subjected to preliminary filtration of impurities, is accurately located and is sealed without being mixed with the impurities is obtained; all components of the whole device can be independently disassembled, assembled and replaced, the structure is simple, the carrying is convenient, durability is realized, the economic benefit is obvious, and the popularization is easy.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and water resource monitoring, in particular to a deep self-filtering sealed water sample collection device and a method thereof. Background technique [0002] In order to ensure the needs of water body testing and monitoring in industries such as environmental protection, water conservancy, water resources, and urban domestic water, it is very important to quickly and accurately obtain water samples at specified locations and depths for accurate evaluation of water quality and pollution. In today's increasingly serious environment and water pollution, fast and accurate water sample filtration and selection technology is very necessary. However, at present, deep water sample collectors are scarce and immature, and the sampling location is not accurate. Due to the lack of sealing of the samples, the mixing of samples affects the quality of water samples, resulting in large deviati...
