Description

Technical Field

[0001] This utility model relates to the field of oil analysis and testing instruments, specifically to a portable spectrometer. Background Technology

[0002] Aircraft engine lubricating oil spectral monitoring is one of the important means of condition-based maintenance. By analyzing the lubricating oil spectrum, the wear condition of the engine, main gearbox, etc. can be monitored. This not only allows for timely prediction of wear-related faults, ensuring flight safety and extending the service life of the aircraft and engine, but also provides scientific guidance for maintenance work, thereby improving maintenance quality and reducing maintenance costs and workload.

[0003] For example, Chinese patent CN222545243U discloses a spectrometer that uses a frequency extension module to convert the frequency of the tunable laser output to a frequency, thereby expanding the bandwidth of the spectrometer and enabling full-band spectral analysis from violet to infrared.

[0004] However, current lubricating oil spectral analysis mainly relies on indoor fixed lubricating oil spectrometers, which generally suffer from problems such as large size, heavy weight, and poor environmental adaptability; the requirements for transport vehicles are high when moving to other locations, and if there are special needs such as field operations, even higher requirements are placed on the time and space for equipment deployment.

[0005] With the increasing demands of the armed forces for combat readiness, duty, relocation training, exercises, and major missions under the new circumstances, existing instruments are difficult to meet the needs of relocation missions and field support. Faced with complicated relocation work conditions and massive testing needs, relying solely on benchtop equipment may affect aircraft training missions. There is an urgent need to improve the portability and wide environmental adaptability of lubricating oil spectrometers.

Both the abrasive particle spectral generation and analysis system 4 and the electrical system 6 are fixedly installed in the equipment installation compartment 11; the abrasive particle spectral generation and analysis system 4 is used to summarize and display the optical path analysis results to the user for operation; the electrical system 6 is used to provide power to the whole machine; like Figure 2 As shown, the abrasive spectroscopy generation system 2 includes a mounting plate 21, an oil inlet assembly 22, a disk electrode 23, a rod electrode 24, and a fixed gap moving structure 25. The mounting plate 21 is fixedly installed inside the excitation chamber 13. A disk motor 231 is fixedly installed on the mounting plate 21. The output end of the disk motor 231 passes through the mounting plate 21 and is fixedly connected to the disk electrode 23. An oil inlet assembly 22 for moving the oil boat 7 is installed on the mounting plate 21 below the disk electrode 23. A fixed gap moving structure 25 for clamping the rod electrode 24 is installed on the mounting plate 21 above the disk electrode 23.

[0023] The testing chamber 12 is also equipped with a temperature control system 5 for adjusting the temperature inside the testing chamber 12.

[0024] The box 1 has a rotating handle, and the bottom of the box 1 is symmetrically equipped with rotating casters. The inner lining of the box 1 is made of conformal rigid foam.

[0025] The abrasive spectral detection system 3 includes a constant voltage variable frequency arc generator, an optical signal acquisition device, a multi-element oil analysis system based on a CCD multicolor meter, a concave collecting mirror and a CCD detector, and a data acquisition and processing module.

[0026] The abrasive particle spectral generation and analysis system 4 uses a multi-functional abrasive particle analyzer, and its external display device uses a ruggedized laptop with strong environmental adaptability instead of a traditional display screen and keyboard.

[0027] In this embodiment, when the portable spectrometer is working normally, the oil boat 7 containing the oil sample is placed on the oil inlet assembly 22, and the rod electrode 24 is installed on the fixed gap moving structure 25. The fixed gap moving structure 25 is used to position and adjust the end position of the rod electrode 24 so that a fixed gap is formed between the rod electrode 24 and the disk electrode 23. Then, the oil inlet assembly 22 is adjusted so that the disk electrode 23 is immersed in the oil sample in the oil boat 7. The disk motor 231 drives the disk electrode 23 to rotate, which moves the oil sample in the oil boat 7 between the disk electrode 23 and the rod electrode 24, while controlling the constant... The high-voltage variable frequency arc generator operates and generates a high-frequency pulsed arc at the excitation gap to excite the oil sample. Under the high-voltage pulsed arc, different metal abrasive particles in the oil sample undergo energy level transitions and generate characteristic spectral signals of different wavelengths. These characteristic spectral signals are collected by an optical signal acquisition device and transmitted via deep ultraviolet fiber to a multi-element oil analysis system based on a CCD multicolor meter. The light entering the multi-element oil analysis system based on a CCD multicolor meter (hereinafter referred to as the multicolor meter) passes through a beam-limiting slit. The spectral signal after being beam-limited by the slit is collimated by a concave collimating lens and reflected onto the surface of a planar diffraction grating. The measured spectrum is spatially separated according to different wavelengths by the grating and corresponding to different pixels on the linear CCD, and then projected onto the surface of the concave collecting mirror. The collecting mirror focuses and reflects the different dispersive spectra into the CCD detector. The CCD detector converts the received spectral signals into corresponding electrical signals and outputs them to the data acquisition and processing module. The processed data is then transmitted to the abrasive spectral generation and analysis system 4. The abrasive spectral generation and analysis system 4 performs a series of calculations, such as item-by-item analysis and statistical analysis of the concentration of various abrasive elements in the oil sample, and provides data and curves that can be stored and read. This invention reduces the size of the equipment by integrating and optimizing the structural layout, making the equipment easy to carry. Through the optimized oil inlet assembly 22 and the fixed gap moving structure 25, the excitation gap between the disc electrode 23 and the rod electrode 24 is kept stable, and the disc electrode 23 is easy to immerse into the oil sample in the oil boat 7, thereby facilitating stable operation.

[0028] Example 2: In some embodiments, as a preferred embodiment of this utility model, such as Figure 4 and Figure 5As shown, the oil inlet assembly 22 includes a movable support module and a lifting module. The movable support module is mounted on the mounting plate 21, and the mounting plate 21 is equipped with a lifting module for moving the movable support module. The mobile support module includes a mobile base 221, a guide rail 222, and a rotating wheel 223. The guide rail 222 is symmetrically fixedly mounted on the mounting plate 21, and the mobile base 221 is slidably connected to the guide rail 222. The rotating wheel 223 is rotatably mounted on the lower side of the mobile base 221. The mobile base 221 is provided with a conformal groove for supporting and limiting the oil boat 7. The lifting module includes an operating knob 224, a rotating shaft 225, a cam block 226, a limiting platform 227, and a limiting block 228. The rotating shaft 225 is rotatably mounted on the mounting plate 21, and the operating knob 224 is fixedly mounted on the outer end of the rotating shaft 225. The cam block 226 is fixedly mounted on the rotating shaft 225 and is rotatably connected to the rotating wheel 223. The limiting platform 227 is fixedly mounted on the lower side of the moving seat 221, and the limiting block 228 is fixedly mounted on the cam block 226.

[0029] The fixed gap moving structure 25 includes a moving adjustment module and a clamping module. The moving adjustment module is mounted on the mounting plate 21, and the moving end of the moving adjustment module is equipped with a clamping module for clamping the rod electrode 24. The movable adjustment module includes a push cylinder 251, a guide rod 252, a movable plate 253, and a push cylinder 255. The push cylinder 251 is fixedly mounted on the mounting plate 21, and the guide rod 252 is symmetrically fixedly mounted on the mounting plate 21. The movable plate 253 is slidably connected to the guide rod 252. The output end of the push cylinder 251 is fixedly connected to the movable plate 253. The push cylinder 255 is fixedly mounted on the movable plate 253. The clamping module includes a fixed clamping plate 254 and a rotating clamping plate 256.

The fixed gap moving structure 25 also includes a positioning plate 257, which is fixedly installed on the moving base 221 for positioning the rod electrode 24.

[0030] In this embodiment, when the mounting plate 21, oil inlet assembly 22, disc electrode 23, rod electrode 24 and fixed gap moving structure 25 are working normally, the oil boat 7 is placed in the conformal groove on the moving seat 221; at this time, the disc electrode 23 does not obstruct the insertion of the oil boat 7; when in use, the operating knob 224 is rotated, and the operating knob 224 drives the cam block 226 to rotate through the rotating shaft 225 until the limiting stage 227 contacts the limiting block 228. During this process, the cam block 226 pushes the rotating wheel 223 to move, and the rotating wheel 223 drives the moving seat 221 to move vertically under the limiting action of the guide rail 222, thereby driving the oil boat 7 on the moving seat 221 to move vertically upward, so that the disc electrode 23 is immersed in the oil sample of the oil boat 7; The rotating clamp 256 is operated to open the angle between the rotating clamp 256 and the fixed clamp 254, causing the torsion spring between them to twist. The rod electrode 24 is then placed into the V-groove of the fixed clamp 254, which positions the rod electrode 24. The rotating clamp 256 is then released, and the rod electrode 24 is clamped and fixed by the rotating clamp 256 and the fixed clamp 254. Then, the second push cylinder 255 moves the rotating clamp 256 and the fixed clamp 254, moving the rod electrode 24 to the upper side of the positioning plate 257. The first push cylinder 251 moves the moving plate 253 vertically downward under the limiting action of the guide rod 252, allowing the rod electrode to... The end of electrode 24 contacts the positioning plate 257. The positioning plate 257 pushes the rod electrode 24 to move upward between the fixed clamping plate 254 and the rotating clamping plate 256, thereby fixing the length of the rod electrode 24 on the lower side of the fixed clamping plate 254 and the rotating clamping plate 256. Then, the push cylinder 1 251 drives the moving plate 253 to reset, and the push cylinder 255 drives the fixed clamping plate 254 and the rotating clamping plate 256 to reset, thereby moving the rod electrode 24 to the upper side of the disk electrode 23, and the end of the rod electrode 24 maintains a fixed gap with the disk electrode 23. The disk motor 231 drives the disk electrode 23 to rotate, thereby driving the oil sample between the disk electrode 23 and the rod electrode 24 through the disk electrode 23, which facilitates subsequent excitation.
