[0037] For example, Figure 2 The exploded view of the assembly structure of the spectral sensor assembly provided in the embodiment of the present application is as follows: Figure 2 As shown, the spectral sensor assembly 1 includes: a component analysis module 1.1.1, a component analysis module fixing bracket 1.1.2, a light source 1.1.3, a light source fixing bracket 1.1.4, a right-angle prism assembly 1.1.5, a spectral light path fixing seat 1.1.6, an optical path rod 1.1.7, a dichroic mirror assembly 1.1.8, and a first lens fixing seat assembly 1.1.9.

[0038] Among them, the right-angle prism assembly 1.1.5 includes: a right-angle prism, a filter, and a right-angle prism fixing bracket; the dichroic mirror assembly 1.1.8 includes: a dichroic mirror and a dichroic mirror fixing bracket; the first lens fixing seat assembly 1.1.9 includes: a lens fixing seat, a lens, and a filter.

[0039] In this embodiment, the various components in the right-angle prism assembly can be bonded together by glue; the various components in the dichroic mirror assembly can be bonded together by glue; and the various components in the lens holder assembly can be bonded together by glue.

[0040] Optionally, during assembly, first secure the first lens holder assembly 1.1.9 to the slot of the spectral light path holder 1.1.6 with screws.

[0041] For example, Figure 3 A schematic diagram of the structure of the armored pipe welding assembly provided in the embodiment of the present application is shown in FIG. Figure 3 As shown, it may include: an armored tube 1.2.1, a flange 1.2.2, an adapter welding head 1.2.3, and a sensor adapter 1.2.4; after the armored tube 1.2.1, the flange 1.2.2, the adapter welding head 1.2.3, and the sensor adapter 1.2.4 are welded together, they are inserted into the first O-ring 1.2.5.

[0042] For example, Figure 4 A schematic diagram of the structure of the spectral visual window assembly provided in the embodiment of the present application is shown in FIG. Figure 4 As shown, it may include: a threaded pressure ring 1.4.1, a second lens 1.4.2, a quartz glass pressure ring 1.4.3, quartz glass 1.4.4, a second O-ring 1.4.5, a third O-ring 1.4.6, and a spectral visual window 1.4.7.

[0043] Optionally, the seal between quartz glass 1.4.4 and spectral visual window 1.4.7 is primarily secured by a third O-ring 1.4.6. Quartz glass pressure ring 1.4.3 is threadedly connected to spectral visual window 1.4.7, compressing quartz glass 1.4.4 against third O-ring 1.4.6 to form a primary seal. The secondary seal is primarily secured by injecting epoxy resin through the adhesive seal of quartz glass pressure ring 1.4.3, sealing spectral visual window 1.4.7, quartz glass 1.4.4, and quartz glass pressure ring 1.4.3 together with the epoxy resin.

[0044] Optionally, during assembly, first place third O-ring 1.4.6 into the sealing groove in spectral visual window 1.4.7. Then, insert quartz glass 1.4.4 and tighten quartz glass pressure ring 1.4.3 through threads. Place second lens 1.4.2 into the lens groove in quartz glass pressure ring 1.4.3 and tighten by threading threaded pressure ring 1.4.1. Next, inject epoxy resin through the adhesive seal of quartz glass pressure ring 1.4.3, sealing spectral visual window 1.4.7, quartz glass 1.4.4, and quartz glass pressure ring 1.4.3 together with epoxy resin to provide a secondary seal. Finally, place second O-ring 1.4.5 over the external threaded groove in spectral visual window 1.4.7. Quartz glass 1.4.4 is the pressure-bearing component, and the seal between it and spectral visual window 1.4.7 is primarily provided by third O-ring 1.4.6.

[0045] For example, Figure 5 A schematic diagram of the structure of the spectral sensor assembly provided in the embodiment of the present application is shown in FIG. Figure 5 As shown, it may include: a spectral optical path component 1.1, an armored tube welding component 1.2, a centering block 1.3, and a spectral visual window component 1.4.

[0046] Optionally, during assembly, first place the spectral optical path assembly 1.1 into the armored tube welded assembly 1.2 as shown and secure it with four screws. Next, screw the centering block 1.3 into the armored tube welded assembly 1.2 as shown, and finally screw on the spectral visual window assembly 1.4. Centering block 1.3 is used to center the spectral optical path assembly 1.1. The seal between the spectral visual window assembly 1.4 and the armored tube welded assembly 1.2 is achieved by pressing a second O-ring 1.4.5 into the sealing groove of the armored tube welded assembly 1.2.

[0047] Optionally, the sealing between the spectral visual window assembly 1.4 and the armored tube welding assembly 1.2 is mainly achieved by sealing the second O-ring 1.4.5 on the spectral visual window assembly 1.4 and the sealing groove at the end of the armored tube welding assembly 1.2, and the spectral visual window assembly 1.4 and the armored tube welding assembly 1.2 are connected by threads.

[0048] For example, Figure 6 A schematic diagram of a light path structure provided in an embodiment of the present application is shown in FIG. Figure 6As shown, it may include: quartz glass I / 1, second lens I / 2, dichroic mirror I / 3, second filter I / 4, first lens I / 5, component analysis module I / 6, light source I / 7, first filter I / 8, and right-angle prism I / 9; wherein, quartz glass I / 1 is used to pass the light beam and withstand pressure; second lens I / 2 is used to converge light to improve the imaging quality of the optical system; when placed at a certain angle, dichroic mirror I / 3 can reflect light of a specific wavelength emitted by the light source and transmit light of a specific wavelength; second filter I / 4 is used to filter out light other than the specific wavelength; first lens I / 5 is used to converge light to improve the imaging quality of the optical system; component analysis module I / 6 is used to convert the received light signal into a component analysis result, and then upload the component analysis result to the host computer; light source I / 7 is used to excite the output light source; right-angle prism I / 9 is used to deflect the light path and deflect the image formed by the optical system by 90°.

[0049] In this embodiment, light source I / 7 emits excitation light of a specific wavelength (such as a laser or LED) as the initial optical signal. The excitation light then passes through first filter I / 8 to filter out stray light of non-target wavelengths, ensuring the purity of the light source. The light passing through first filter I / 8 is then deflected 90° by right-angle prism I / 9 to accommodate the system's spatial layout. After being redirected by right-angle prism I / 9, the light passes through dichroic mirror I / 3, where it reflects the excitation light from the light source. The reflected light passes through second lens I / 2 and then through quartz glass I / 1 to enter the medium. Quartz glass protects internal components because it is both light-transmitting and pressure-bearing. Second lens I / 2 initially focuses the light to enhance light intensity and image quality. The light passing through second lens I / 2 then passes through dichroic mirror I / 3 to produce detection light. The detection light then undergoes secondary filtering by second filter I / 4 to further remove interfering wavelengths. The transmitted light, after passing through second filter I / 4, is refocused by first lens I / 5 to optimize signal reception efficiency. The component analysis module I / 6 receives the refocused light and converts it into an electrical signal. Finally, it uses an algorithm to analyze the sample composition (such as substance concentration or structural information) and uploads the component analysis results to the host computer.

[0050] The online detection spectrometer in this embodiment has a simple and compact structure, is easy to install and adjust, and its pressure-bearing structure can withstand a pressure of at least 3 MPa without leakage. It is suitable for online detection of liquid components in pipelines, is easy to use, and has high accuracy.

[0051] In this embodiment, the liquid composition in the pipeline can be detected online according to customer needs, and its abnormal conditions can be monitored in real time.

[0052] This embodiment has a compact and simple structure, relying on the close coordination of various optical components and achieving light transmission through reflection. It has the advantages of a simple light path and easy assembly and adjustment, can effectively improve the integration and stability of the system, and has broad application prospects.
