[0002] Spectrophotometry is a method for qualitative and quantitative analysis of a substance by measuring its absorbance or luminescence intensity at a specific wavelength or within a certain wavelength range. It is widely used in water quality testing. However, existing spectrophotometric water quality testing instruments often have a single-path optical transmission and reception module, meaning only one wavelength of light can be detected at a time. This results in longer testing times when analyzing samples. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a multi-channel optical path transmitting and receiving module device, which connects to multiple optical path channels. This allows for the simultaneous processing of multiple wavelength channels or multiple sample channels during detection, significantly shortening the detection time.

[0004] The technical solution adopted by this utility model is: a multi-channel optical path transmitting and receiving module device, including an assembly bottom cover, an optical channel fixing component, an assembly top cover, a transparent light-transmitting component, and a fixed outer shell. The transparent light-transmitting component is cylindrical, and the assembly bottom cover has an inwardly recessed positioning groove for inserting the end of the transparent light-transmitting component. The optical channel fixing component is installed between the assembly bottom cover and the assembly top cover, and both the optical channel fixing component and the assembly top cover have through holes for the transparent light-transmitting component to pass through. The assembly bottom cover has multiple insertion holes for inserting optical fibers, and the transparent light-transmitting component has mating holes corresponding to the multiple insertion holes. The assembly bottom cover and the assembly top cover are fixed to the assembly top cover by positioning bolts.

[0008] Preferably, the end of the optical channel fixing member that is close to the color position fixing member has an inwardly recessed insertion cavity for the end of the colorimetric tube to be inserted.

[0009] Preferably, the inner side of the optical channel fixing component is provided with an inwardly recessed limiting groove, and the mounting bottom cover and mounting top cover are provided with positioning strips that are embedded in the positioning groove.

[0010] Preferably, the fixed outer shell is provided with a colorimetric position fixing component and a colorimetric tube fixing component.

The mounting bottom cover is provided with multiple insertion holes for optical fibers, and the transparent light transmission component is provided with docking holes that correspond one-to-one with the multiple insertion holes.
