Sample pool and device for detecting multiple water quality indexes

Abstract

The invention aims at provides a sample pool and a device for detecting multiple water quality indexes. The sample pool comprises a pool body, a bottom surface of the bottom body at least comprises afirst end and a second end with height difference; the pool body comprises a first box and a second box communicating through a pipeline; a first sliding chute is arranged on a sidewall of the first box, a first connector is inserted into the first sliding chute, and multiple jacks are formed on the first connector form bottom to top; a second sliding chute is arranged on the sidewall of the second box, a second connector is inserted into the second sliding chute, and multiple insertion bars are arranged on the second connector from bottom to top; the second insertion bars are inserted into the jacks so as to form a fixed connecting structure for the first box and the second box. The relative height between different boxes of the sample pool is adjustable, the sample depth can be adjustedaccording to a detection probe, the sample dosage can be effectively saved, the working efficiency is improved at the same time, and the sample pool is more suitable for practical.

Description

technical field [0001] The invention relates to the field of environmental testing equipment, in particular to a sample pool and multiple water quality index testing devices. Background technique [0002] The sample pool refers to the container used to hold the sample during the sample detection process, so that the detection probe can fully contact with the sample to complete the detection. [0003] The design of the sample pool used in the existing water quality testing equipment is relatively simple. When performing multiple water quality testing indicators, multiple detection probes are all placed in one sample pool, and the detection probes for some indicators, such as COD detection probes, It requires the sample liquid level to completely submerge the probe column to perform detection, while some indicator detection probes, such as ammonia nitrogen, DO, SS detection probes, only need the sample liquid level to submerge the sensor at the bottom of the probe. However, i...

Problems solved by technology

However, in the existing sample pool, when performing multiple water quality testing indicators, multiple detection probes are all placed in one sample pool. In order to ensure that each detection probe can perform detection, the sample liquid level needs to submerge all detection probes , that is, the liquid level in the sample pool must at least meet the requirements of the detection probe with the highest sample liquid level. In this way, the sample pool needs to inject a sample with a relatively high liquid level within a relatively large cross-sectional range. In fact, many detection probes do not The need for such a high sample liquid level results in a large demand for testing samples and waste of cost; moreover, because of the large demand for samples, it also results in a long time for sample injection and waste liquid discharge in the existing sample pool, and low work efficiency
