[0002] Water quality testing is a crucial part of environmental monitoring and water resource management. Traditional water quality testing often employs chemical reagent colorimetric methods or laboratory analysis methods. While these methods can obtain highly accurate data, they often suffer from problems such as complex testing processes, long processing times, strong dependence on operators, and inconvenience for rapid on-site testing. In recent years, water quality testing methods based on spectral analysis technology have gradually gained attention. Spectroscopic detection utilizes the absorption, transmission, or scattering characteristics of water samples at specific wavelengths of light to analyze the composition and concentration of substances in the water. Its advantages include fast detection speed, no need to add reagents, and the ability to monitor multiple parameters simultaneously.

[0003] However, in the existing technology, the optical path structure of the modular spectral water quality analyzer lacks a structure for flexibly adjusting the position of the grating, which leads to the problem that the grating can only work in a single spectral range during actual use.

[0033] Reference Figure 4 and Figure 5 The inner wall of the U-shaped body 10 is rotatably connected to a support rod 9, and the outer wall of the support rod 9 is fixedly connected to a pulley 27.

[0034] Specifically, the U-shaped body 10 serves to limit and support the support rod 9. When the support rod 9 rotates, it rotates around the inner wall of the U-shaped body 10 as the center. The support rod 9 moves the pulley 27.

[0035] Reference Figure 3 and Figure 5 The outer wall of pulley 27 is slidably connected to the inside of rotating frame 28, and the outer wall of fixed frame 2 is fixedly connected to U-shaped body 3 14.

[0036] Specifically, the rotating frame 28 supports and guides the pulley 27. When the support rod 9 rotates, it will cause the pulley 27 to slide on the inner wall of the rotating frame 28. The fixed frame 12 fixes the U-shaped body 3 14.

[0037] Reference Figure 3 The U-shaped body 3 14 is internally connected to a worm gear 2 13, and the U-shaped body 3 14 is internally connected to a handle 26.

[0038] Specifically, the worm gear 213 drives the U-shaped body 314 to rotate when the worm gear 213 rotates. The U-shaped body 314 limits and supports the handle 26. When the handle 26 rotates, it rotates around the inner wall of the U-shaped body 314.

[0039] Reference Figure 3 The outer wall of the handle 26 is fixedly connected to the outer end of the worm gear 13, and the tooth end of the worm gear 13 is engaged with the half worm wheel 12.

[0040] Specifically, the handle 26 drives the worm gear 13. When the handle 26 is turned manually, the handle 26 drives the worm gear 13 to rotate. The worm gear 13 drives the half worm wheel 12 to rotate. The rotation of the worm gear 13 drives the half worm wheel 12 to rotate.

[0042] Specifically, the U-shaped body 10 supports and limits the semi-worm gear 12. When the semi-worm gear 12 rotates, it rotates around the inner wall of the U-shaped body 10. The semi-worm gear 12 drives the support rod 9 to rotate when the worm gear 13 rotates.

[0043] Working principle: When adjusting the position of grating 23, motor 2 16 is started first. The output end of motor 2 16 rotates, driving the drive wheel 17 to rotate. The drive wheel 17 rotates, driving the conveyor belt 18 to rotate. The conveyor belt 18 rotates, driving the driven wheel 19 to rotate. The rotation of the drive wheel 17 and the driven wheel 19 drives the conveyor belt 18 to rotate continuously. During the rotation of the conveyor belt 18, the fixed block 22 moves along the inner wall of the fixed frame 2 15. The movement of the fixed block 22 drives the slider 21 to slide along the inner wall of the slide rail 20. The movement of the slider 21 drives the grating 23 to move. By adjusting the position of grating 23, the position of grating 23 can be flexibly adjusted to cover different wavelength ranges. This solves the limitation of traditional fixed grating 23 working only in a single spectral range, which is conducive to realizing multi-parameter water quality detection and improving the versatility of the instrument.

[0044] When adjusting the left and right angles of the reflector 8, motor 4 is started first. The output of motor 4 rotates, driving worm gear 5 to rotate. Worm gear 5 meshes with half-worm wheel 6. The rotation of worm gear 5 drives half-worm wheel 6 to rotate, which in turn drives support column 7 to rotate. The rotation of support column 7 causes the reflector 8 to swing left and right. When adjusting the up and down angles of the reflector 8, handle 26 is turned first. The rotation of handle 26 drives worm gear 13 to rotate. Worm gear 13 meshes with half-worm wheel 12. The rotation of worm gear 13 drives half-worm wheel 12 to rotate, which in turn drives support rod 9 to rotate. The rotation of support rod 9 causes the up and down angles of the reflector 8 to be adjusted. By adjusting the left and right and up and down angles of the reflector 8, the optical path can be quickly calibrated, which is beneficial to improving the stability of spectral detection and the accuracy of signal acquisition.

[0045] In practical use, the optical path structure of this modular spectrometer water quality analyzer not only allows for flexible adjustment of the grating 23 position to cover different wavelength ranges, but also enables rapid calibration of the optical path.
