Abstract

The invention provides a water quality sample collector which comprises a cylinder body (10), openings are formed in two ends of the cylinder body (10), and a handle (13) is arranged on the cylinder body (10); a filter screen (11) and a blade type one-way valve (12) are arranged at an opening in a bottom end of the cylinder body (10), the blade type one-way valve (12) is located above the filter screen (11), and the filter screen (11) is used for filtering impurities in water; and the blade type one-way valve (12) can be opened under the action of water flow and is sealed under the action of gravity of water. According to the water quality sample collector provided by the invention, the filter screen is arranged at the opening in the bottom such that a water sample can be filtered in a collecting process, the subsequent work is simplified, and the representativeness of the water sample is also ensured. The blade type one-way valve can enable water to smoothly enter the cylinder body and guide the water to slowly rotate and rise, a water sample on the same layer as a sampler is reserved, and the primitiveness, representativeness and scientificity of the sample are guaranteed.

Description

technical field [0001] The invention relates to the field of water quality sample collection in the water environment monitoring process in an ecological environment, in particular to a water quality sample collector. Background technique [0002] The collection of water quality samples in the field of water environment generally uses water quality sample collectors (also called water quality samplers), which are used to collect water quality samples from water bodies for laboratory analysis and testing. In order to ensure the scientificity and representativeness of water quality sample collection, samples must be collected in accordance with relevant national standards. In order to ensure the accuracy and reliability of the sample monitoring results, the samples need to be processed and packaged on-site according to the relevant national testing standards. The existing water quality sampler has a simple structure, which is a simple cylinder structure. Due to the limitation...
