Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a spectrometer structure dedicated to water quality detection. Background Art

[0002] Water quality testing is an important means of ensuring water resource safety. Through systematic analysis of water samples, toxic and hazardous substances such as heavy metals, organic pollutants, and pathogens can be promptly detected. This is crucial for preventing water pollution and protecting human health. In addition, water quality testing results can guide the selection and optimization of sewage treatment processes and provide data support for the formulation of environmental protection policies. With the accelerated pace of industrialization and urbanization, my country's demand for water resources has increased dramatically, and the problem of water pollution has become increasingly prominent. Water quality testing is responsible for monitoring and measuring the types, concentrations, and changing trends of pollutants in water bodies to assess water quality.

[0003] Spectrometers are often used in existing detection methods to analyze and detect water quality color and concentration. The collected water samples often need to be centrifuged before testing to separate impurities and water samples. When the samples are centrifuged, the test tubes are prone to shaking in the equipment, which can easily cause liquid to spill or cause the test tubes to be damaged by force and collision. Therefore, a spectrometer structure dedicated to water quality testing is needed to meet people's needs. Utility Model Content

[0023] In order to realize the function of fixing the test tube 12, the first fixing device 2 includes a first fixing barrel 20, the first fixing barrel 20 is installed on the rotating platform 8, a first fixing block 25 is installed in the first fixing barrel 20, a first spring 26 is installed on one side of the first fixing block 25, the first fixing block 25 and the first spring 26 are both circumferentially distributed in the first fixing barrel 20, a first fixing groove 24 is opened in the first fixing barrel 20, the first fixing block 25 and the first spring 26 are both installed in the first fixing groove 24, a first test tube cavity 21 is opened in the first fixing barrel 20, the first test tube cavity 21 is opened in the center of the circumferential division of the first fixing block 25, a top protrusion groove 23 is opened on the upper surface of the first fixing barrel 20, and a bottom protrusion groove 22 is opened on the lower surface of the first fixing barrel 20. A platform protrusion 9 is installed on the platform 8, and the platform protrusion 9 is installed in the bottom protrusion groove 22. A first motor 6 is installed in the detection device body 1, and a first rotating shaft 7 is installed on the first motor 6.

At the same time, in order to maintain the stability of the test tube 12, the threaded rod 41 can be rotated. When the threaded rod 41 rotates, the upper cover 40 moves up and down, so that the pressure plate 43 is pressed on the top of the test tube 12, which can press the top of the test tube 12 and fix the test tube 12 while preventing the liquid in the test tube 12 from spilling.
