The space between the connecting sleeve 61 and the detection channel 5 is an annular groove 62. The bottom of the light-shielding sheath 63 is inserted into the inner side of the annular groove 62, so that the light-shielding sheath 63 is sleeved on the top of the detection channel 5 to prevent external light from entering the detection channel 5 and causing interference. A bracket 64 is adhesively provided on the front wall surface of the analysis chamber 4, and the connecting sleeve 61 can be horizontally placed inside the bracket 64.

[0025] Further explanation, the whole light-shielding sheath 63 is made of non-light-transmitting material, so that the light-shielding sheath 63 can provide a good light-shielding environment for the detection channel 5.

[0026] Further explanation, the depth of the annular groove 62 is not less than 2 cm, so that the light-shielding sheath 63 and the connecting sleeve 61 have sufficient connection length to ensure the installation stability.

[0027] Please refer to Figures 5 - 6 , the present utility model provides a device for analyzing and detecting total nitrogen in water quality. The light-shielding sheath 63 is composed of an upper sleeve body 631 and a lower sleeve body 632. The upper sleeve body 631 is the upper half of the light-shielding sheath 63, and the lower sleeve body 632 is the lower half of the light-shielding sheath 63. The inside of the upper sleeve body 631 and the lower sleeve body 632 is connected. A threaded sleeve 633 is integrally provided at the bottom of the upper sleeve body 631, and a threaded groove 634 is provided at the upper part of the inner side of the lower sleeve body 632.

[0028] Further explanation, the height of the threaded sleeve 633 is not less than 4 cm, and the depth of the threaded groove 634 is the same as the length of the threaded sleeve 633, so that the light-shielding sheath 63 has sufficient adjustment margin to better adapt to test tubes of different length specifications.

[0029] Further explanation, a rubber ring 632a is sleeved on the outer surface of the bottom of the lower sleeve body 632. The height of the rubber ring 632a is the same as the depth of the annular groove 62. The rubber ring 632a can play a filling role between the lower sleeve body 632 and the annular groove 62 to ensure the installation stability of the light-shielding sheath 63 and the connecting sleeve 61.

[0030] The working principle is as follows:

[0031] First, first connect the power cord 3 to an external power supply interface to ensure the normal power supply of the analyzer main body 1. Then open the analysis chamber 4 and insert the test tube loaded with the sample into the detection channel 5. Subsequently, start the analysis program through the control panel 2, so that the analyzer main body 1 measures the total nitrogen content in the sample, thereby realizing the analysis and detection of total nitrogen in water quality.

[0032] Second, by arranging a light-shielding device 6 outside the detection channel 5, after the test tube is inserted into the detection channel 5, the light-shielding sheath 63 is sleeved on the surface of the test tube from top to bottom, and the light-shielding sheath 63 is continuously moved downward until the bottom of the light-shielding sheath 63 is inserted into the inner side of the annular groove 62, thereby completing the assembly of the light-shielding sheath 63 and the detection channel 5. The light-shielding sheath 63 can provide a good light-shielding environment for the detection channel 5, avoid external light entering the detection channel 5 to cause interference, and ensure the detection accuracy.

[0033] Third, when the light-shielding sheath 63 is in use, the upper sleeve body 631 and the lower sleeve body 632 can be rotated separately. When the threaded sleeve 633 is screwed out of the threaded groove 634, the distance between the upper sleeve body 631 and the lower sleeve body 632 increases, so that the length of the light-shielding sheath 63 extends. When the threaded sleeve 633 is screwed into the threaded groove 634, the distance between the upper sleeve body 631 and the lower sleeve body 632 decreases, so that the length of the light-shielding sheath 63 shortens. The use length of the light-shielding sheath 63 can be adjusted to better adapt to test tubes of different length specifications.

[0034] Fourth, after use, the light-shielding sheath 63 is pulled out of the annular groove 62 and then placed horizontally on the bracket 64, which is convenient for storage and not easy to lose.
