Problems solved by technology
[0005] The invention provides a sample retention bottle, a sample retention device and a method of use to solve the problem that the existing sample retention bottle needs to transfer the sample to be brought back to the laboratory for testing, and the sample retention bottle containing the sample cannot be directly removed from the sample retention system. When taking it out, and when taking it out, the reserved sample bottle cannot be automatically sealed, which may easily cause the problem of water sample fraud

The invention discloses a sample reserving bottle, a sample reserving device and a using method. The sample reserving bottle comprises a bottle body, the bottle body is internally provided with at least one bottle opening communicated with a bottle cavity, the bottle opening is provided with a self-sealing mechanism capable of achieving self-sealing, the self-sealing mechanism comprises a bottle cap covering the bottle opening, the bottle cap is provided with a mounting hole, a sealing shaft and an elastic unit, the mounting hole is formed in the bottle cap, and forms a through hole penetrating through the inside and the outside of the bottle cap. The sealing shaft is arranged in the mounting hole in a penetrating manner and extends along the axis of the mounting hole; a channel is formed in the extending end, extending out of the bottle cap, of the sealing shaft, and the channel and the bottle cavity can be arranged in a sealed and communicated mode; the two ends of the elastic unit abut against the bottle cap and the sealing shaft respectively. According to the sample reserving bottle, the bottle cap does not need to be unscrewed and screwed in the whole sampling process, operation is easy, the sampling efficiency is high, a sample is not prone to being polluted, and it is ensured that the sample detection result is accurate.
Description
technical field [0001] The present invention relates to the technical field of water quality sample retention system, in particular, to a sample retention bottle, and furthermore, to a sample retention device and its use method. Background technique [0002] In order to check the validity of the test results of the water quality online monitor, one of the existing quality control methods is to collect water samples to the laboratory for laboratory analysis, and compare the test results of the water quality online monitor with the laboratory analysis results. Compare to judge. At present, there are two main methods of sampling: manual sampling and on-site sample retention system for automatic sample retention. [0003] Existing sample holders are all connected by closed pipelines, and the water sample is generally transported to the sample bottle by a peristaltic pump, and then the storage and discharge of the water sample in the sample bottle is controlled by a pinch valve....
