Description

Water quality measuring analyzer

Technical Field

The application relates to the field of water quality analysis equipment, in particular to a water quality measurement analyzer.

Background

COD is the amount of oxygen required to oxidize organic matter in water, known as chemical oxygen demand, and can directly reflect the degree of pollution of a water body by various reducing substances. The principle of measuring COD in water is that the COD parameters of the sample are obtained by reacting enough strong oxidant with all organic matters in the measured sample, measuring the consumption difference of the strong oxidant and calculating through a specific formula. In practice, a COD water quality analyzer is generally used to measure the COD content of water.

The Chinese patent with the bulletin number of CN219224758U discloses a COD water quality analyzer, when the COD water quality analyzer is used, a protective box body and a protective cover body are locked by virtue of a closed lock in the normal moving process, the COD water quality analyzer is sleeved in an assembly seat on the inner side of the protective box body, the assembly seat is used for assembling and protecting the COD water quality analyzer, a certain gap is formed between the protective box body and the assembly seat, and the gap is fixed by a buffer board which is uniformly distributed. The assembly seat is provided with grooves which are uniformly distributed on two sides of the COD water quality analyzer, the grooves are sleeved with sample tubes, the extracted water quality samples are stored through the sample tubes, the sample tubes are placed into the COD water quality analyzer for analysis in an analysis stage, the storage battery stores electric energy through a power connector, when the COD water quality analyzer needs to be operated for water quality analysis, the storage battery provides working energy for the COD water quality analyzer, the COD water quality analyzer carries out a COD water quality analysis process on the samples in the sample tubes, and analysis data are displayed on a display screen of the COD water quality analyzer.

However, in practical application, the sample tube cannot be well fixed only by virtue of the groove on the assembly seat, when the protective box body is impacted, the sample tube is very easy to shake in the groove, so that the sample tube is separated from the groove and collides with the inner wall of the protective box body or the protective cover body, the sample tube is cracked, and the water quality in the sample tube is lost, so that the measurement of the COD water quality analyzer is affected.
