[0035] Referring to Figure 1 , 2The oil detection sensor shown in FIGS. 1, 2, and 3 comprises a base 100, a shell 200, and a detection assembly 300. The base 100 is connected to an external device. The shell 200 is arranged on the surface of the base 100. The shell 200 is internally provided with a main channel 210, a detection channel 220, and two shunt channels 230. The main channel 210 and the detection channel 220 are arranged in parallel. The two shunt channels 230 are respectively connected to the main channel 210 and the detection channel 220. The detection channel 220 is provided with a detection window 221. The detection assembly 300 comprises a dispersion module 310, a light sensing module 320, and a moving module 330. The dispersion module 310 is arranged in the shell 200 and located at one side of the detection window 221, and is used for dispersing white light into light spectra of different wavelengths. The moving module 330 is arranged in the shell 200 and located at the other side of the detection window 221. The light sensing module 320 is arranged on the moving end of the moving module 330 and is used for receiving the light spectra emitted from the detection window 221.

[0036] In the above embodiment, the base 100 is connected to the external device to ensure the stability of the overall structure. The shell 200 is internally provided with the main channel 210, the detection channel 220, and the two shunt channels 230 to form an efficient oil delivery path. The main channel 210 and the detection channel 220 are arranged in parallel. The two ends of the shunt channels 230 are respectively connected to the main channel 210 and the detection channel 220, so that the oil can uniformly flow through the detection area, avoiding the influence of bubbles or sediments on the detection results, thereby improving the detection accuracy. The detection window 221 is arranged on the detection channel 220. The dispersion module 310 is located at one side of the detection window 221 and is used for dispersing the incoming white light into light spectra of different wavelengths and projecting them onto the oil sample. The light sensing module 320 is installed on the movable moving module 330 and located at the other side of the detection window 221. The light sensing module 320 is driven by the moving module 330 to scan the light spectra of different wavelengths along the detection window 221, thereby realizing the step-by-step collection of complete spectral information or the sampling of light spectra in a specified wavelength range. Compared with the prior art, the light sensing module 320 scans the light spectra after passing through the oil in the embodiment of the present application, realizes real-time detection and analysis of the oil composition, and improves the oil composition detection efficiency. The dispersion module 310, the moving module 330, and the light sensing module 320 are integrated in the shell 200, and the overall structure is simple and easy to use, which not only improves the portability of the oil detection, but also reduces the cost of oil composition detection.

[0037] It can be understood that, with reference to Figure 3As shown, the dispersion module 310 includes a light source 311, a bracket 312 and a triangular prism 313, the light source 311 is arranged in the shell 200 and located at one side of the detection channel 220, the bracket 312 is arranged in the shell 200 and located at one side of the light source 311, one end of the bracket 312 is connected with the surface in the shell 200, the triangular prism 313 is connected with the other end of the bracket 312, and the triangular prism 313 is arranged in alignment with the light source 311 and the detection window 221. By integrating the light source 311, the bracket 312 and the triangular prism 313 in the shell 200, a compact and stable structure is formed, external factors are avoided to interfere with the optical path, and the accuracy of oil component detection is improved. The light source 311 is arranged at one end of the detection channel 220, so that the light can effectively enter the triangular prism 313 for dispersion processing, and the triangular prism 313 is fixed by the bracket 312, so that its position is accurately controllable, and deviation of the optical path caused by vibration or displacement is prevented, thereby ensuring consistency of the dispersion effect.

[0038] It can be understood that, referring to Figure 4 As shown, the moving module 330 includes a spiral guide rail 331, a spiral sliding block 332 and a motor 333, the spiral guide rail 331 is arranged in the shell 200 and located at one side of the detection window 221 away from the triangular prism 313, the spiral sliding block 332 is slidably connected with the spiral guide rail 331, and the motor 333 is arranged on the surface of the shell 200 close to the light source 311. One end of the motor 333 is connected with one end of the spiral guide rail 331. Through the sliding cooperation of the spiral guide rail 331 and the spiral sliding block 332, stable and accurate displacement adjustment is realized, so that the light sensing module 320 is accurately positioned. The external design of the motor 333 reduces the interference with the internal optical system, and at the same time provides stable power by driving the spiral guide rail 331, so that the sliding block moves stably, and the oil component detection effect is improved.

[0039] It can be understood that, referring to Figure 4 As shown, the oil detection sensor further includes a temperature detection assembly 400, which is arranged in the shell 200 and located at one side of the detection channel 220 away from the detection window 221. By increasing the temperature detection assembly 400, real-time monitoring of the oil temperature is realized.

[0040] In some embodiments, the temperature detection assembly 400 can employ high-precision thermocouples or resistance temperature detectors as temperature sensors. These sensors have high temperature measurement accuracy and can provide stable and reliable temperature data in real time during oil detection, ensuring a high degree of matching between temperature data and oil composition analysis, thereby optimizing the detection results. The temperature detection assembly 400 can be configured to trigger an alarm when the oil temperature exceeds a predetermined range. The alarm signal can be notified through the display assembly 500 or an externally connected alarm system to remind the staff to handle the abnormal situation in time. In addition, the temperature sensor can also be linked with the control system, and when the temperature is too high, the oil flow can be automatically adjusted or the cooling system can be started to prevent the oil detection sensor from being damaged due to overheating.

[0041] It can be understood that, as shown in Figure 4 , the temperature detection assembly 400 includes a first fixed seat 410 and a temperature sensor, the first fixed seat 410 is connected with the surface of the shell 200 and located beside the end of the detection channel 220 away from the detection window 221, and the temperature sensor is arranged on the surface of the first fixed seat 410. The temperature sensor is stably installed in the shell 200 through the first fixed seat 410. The temperature sensor is in close contact with the surface of the first fixed seat 410, effectively improving the temperature conduction efficiency, and realizing rapid and accurate measurement of the oil temperature in the detection channel 220.

[0042] It can be understood that, as shown in Figure 2 , the cross-sectional area of the main channel 210 is larger than that of the shunt channel 230, and the cross-sectional area of the shunt channel 230 is larger than that of the detection channel 220. By gradually reducing the cross-sectional area of the main channel 210, the shunt channel 230 and the detection channel 220 in turn, the fluid is gradually shunted and controlled, which helps to stabilize the oil flow state and improve the detection accuracy. The larger cross-sectional area of the main channel 210 can ensure sufficient oil supply, and the appropriately reduced cross-sectional area of the shunt channel 230 can effectively regulate the flow rate to avoid interference with the detection caused by excessive flow rate. Finally, the smallest cross-sectional area of the detection channel 220 can accurately control the amount of oil entering the detection area, optimize the measurement environment, and improve the sensitivity of the sensor and the stability of the data, thereby improving the accuracy of oil composition detection.

[0043] It can be understood that, as shown in Figure 2 , 3 , the shell 200 further includes an expansion interface 240, the expansion interface 240 is in communication with the main channel 210, the expansion interface 240 is located on the side of the main channel 210 away from the shunt channel 230, and the number of expansion interfaces 240 matches the number of shunt channels 230. By setting the expansion interface 240, external sensors or devices can be connected to complete more functions.

[0044] For example, as shown in Figure 2、 3 As shown in the drawings, two expansion interfaces 240 are set as an example, both of which are arranged on one side of the shell 200 close to the main channel 210. The two expansion interfaces 240 can be connected to a flow guiding device, which can push the oil liquid in the main channel 210 to the branch channel 230.

[0045] It can be understood that, referring to Figure 1 As shown in the drawings, the oil liquid detection sensor also includes a display assembly 500 arranged on the side of the shell 200 away from the base 100. The independently arranged display assembly 500 can facilitate the staff to view the detection data related to the composition and temperature of the oil liquid in real time.

[0046] In some embodiments, the display assembly 500 adopts a liquid crystal or OLED display screen, which can clearly display various indicators of the oil liquid and support real-time updating. When detecting temperature abnormalities or composition problems, the display assembly 500 will automatically pop up an alarm and prompt the staff through vision or sound. In addition, the display assembly 500 can also be connected with a wireless communication module to realize remote transmission of data, facilitating remote monitoring and management. The modular design makes the display assembly 500 easy to replace, reducing the difficulty of maintenance. In order to adapt to different environments, the display assembly 500 has waterproof and dustproof functions, and can automatically adjust brightness and contrast, ensuring clear display of data under various working conditions. These designs improve the operation convenience, monitoring efficiency and safety of the device.

[0047] It can be understood that, referring to Figure 4 As shown in the drawings, the light sensing module 320 is detachably connected with the mobile end of the moving module 330. Through the detachable structure, the light sensing module 320 can be conveniently replaced, adjusted or maintained without disassembling the entire sensor.

[0048] In some embodiments, the light sensing module 320 and the mobile end of the moving module 330 can be connected in various ways, such as buckle type, threaded connection, magnetic connection, slot type connection, etc. These connection methods not only ensure the stable fixation between the modules, but also facilitate quick disassembly and replacement, providing good flexibility and maintainability.

Through the detachable connection between the first fixing seat 410 and the surface of the shell 200 and the detachable connection between the temperature sensor and the surface of the first fixing seat 410, the flexibility and maintainability of the temperature detection assembly 400 are improved. The detachable first fixing seat 410 facilitates the installation, disassembly and replacement of the temperature detection assembly 400, reduces the difficulty of maintenance, and improves the service life of the equipment. At the same time, the detachable design of the temperature sensor facilitates the replacement of different types or precision sensors to adapt to different detection requirements.

[0050] In some embodiments, the first fixing seat 410 is fixedly connected with the surface of the shell 200 through a screw, so that the temperature sensor can be fixed to the surface of the shell 200, improving the stability and precision of temperature detection.
