Description

Technical Field

[0001] The utility model belongs to the technical field of oil monitoring, and in particular relates to an aircraft oil monitoring device. Background Art

[0002] Aircraft oil monitoring devices (OIL monitoring devices) are devices used to monitor the condition of aircraft lubricants and other fluids. They are crucial to the safe operation of aircraft. These devices can monitor various oil parameters, such as contamination, viscosity, temperature, and chemical composition, in real time or periodically to ensure that the oil maintains optimal performance under normal operating conditions of aircraft systems.

[0003] Currently, traditional aircraft oil monitoring systems usually require these sensor probes to be thoroughly cleaned after use to ensure the accuracy and reliability of the next monitoring. This cleaning process traditionally relies on manual wiping. Although this method can remove dirt on the probes to a certain extent, it is time-consuming and labor-intensive. In addition, the manual cleaning process may have consistency issues and the risk of incomplete cleaning, which may have a potential impact on aircraft maintenance and flight safety. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an aircraft oil monitoring device to solve the problem proposed in the above background art that the traditional aircraft oil monitoring device usually needs to thoroughly clean these sensor probes after use to ensure the accuracy and reliability of the next monitoring. This cleaning process traditionally relies on manual wiping. Although this method can remove dirt on the probe to a certain extent, it is time-consuming and labor-intensive. In addition, the manual cleaning process may have consistency issues and the risk of incomplete cleaning, which may potentially affect the maintenance and flight safety of the aircraft.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aircraft oil monitoring device, comprising an oil tank, an inner surface of the oil tank is provided with a lifting groove, the upper end of the oil tank is fixedly connected to a driving motor, the output end of the driving motor is transmission-connected to a threaded screw, the threaded screw is rotatably connected to the inside of the lifting groove, the surface of the lifting groove is threadedly connected to a lifting block, one side surface of the lifting block is fixedly connected to a monitoring contact through a first connecting rod, both side surfaces of the inner side of the lifting groove are provided with sliding grooves, the inner side of the sliding groove is slidably connected to a slider, one side surface of the slider is fixedly connected to a wiping cotton through a second connecting rod, and two wiping cottons are provided.

[0006] Preferably, the inner side of the slider is a triangular structure, and the inner inclined surface of the slider is rotatably connected to a roller.

[0007] Preferably, a sliding rod is fixedly connected to the interior of the sliding groove, and the sliding block is slidably connected to the surface of the sliding rod.

[0008] Preferably, a spring structure is provided between the sliding block and the inner wall of the sliding groove, and the spring structure is provided on the surface of the sliding rod.

[0009] Preferably, a tank cover is snap-connected to the upper surface of the oil tank.

[0010] Preferably, a control panel is installed on the upper end of the outer surface of the oil tank.

[0011] Preferably, a sensor group is provided inside the lifting block, and the sensor group includes an oil quality sensor, an oil temperature sensor, an oil pressure sensor, a particle counting sensor and a moisture sensor.

[0012] Compared with the prior art, the present invention provides an aircraft oil monitoring device with the following features:

[0013] Beneficial effects:

[0014] 1. The utility model provides structures such as wiping cotton. Before the monitoring contact monitors the aircraft oil inside the oil tank through the monitoring contact, the driving motor drives the threaded screw to rotate, so that the lifting block descends inside the lifting slot. During the descent, the monitoring contact passes between the two wiping cottons, and the surface of the monitoring contact is wiped and cleaned by the wiping cotton, thereby ensuring the accuracy of the monitoring. After the monitoring is completed, the monitoring contact passes through the wiping cotton again during the process of rising, and is cleaned twice by the wiping cotton, thereby further ensuring the neatness of the monitoring contact surface, effectively avoiding the traditional aircraft oil monitoring device. The sensor probes usually need to be thoroughly cleaned after use to ensure the accuracy and reliability of the next monitoring. This cleaning process traditionally relies on manual wiping. Although this method can remove dirt on the probe to a certain extent, it is time-consuming and labor-intensive. In addition, the manual cleaning process may have consistency problems and the risk of incomplete cleaning, which may have potential impacts on aircraft maintenance and flight safety.

[0015] 2. The utility model is provided with a slider and roller structures. When the lifting block passes the slider, the rolling of the roller and the squeezing of the slider make the two sliders on both sides slide outward. At this time, the spring structure is squeezed and is in a compressed state. When the lifting block passes the position of the slider, the restoring elastic force of the spring structure squeezes the slider toward the middle, causing the slider to reset, thereby preventing the slider from restricting the normal lifting of the lifting block.

[0016] 3. The utility model is provided with a lifting block and a sensor group provided inside the lifting block, and the sensor group includes an oil quality sensor, an oil temperature sensor, an oil pressure sensor, a particle counting sensor and a moisture sensor. The oil quality sensor is responsible for monitoring the quality of the oil and evaluating the degree of contamination of the oil by detecting changes in its dielectric constant; the oil temperature sensor monitors the temperature of the oil in real time to ensure that the oil works within an appropriate temperature range to prevent overheating or overcooling from causing damage to the engine; the oil pressure sensor is used to monitor the pressure of the oil to ensure that the oil flows smoothly between the various components of the engine to ensure lubrication and cooling effects; the particle counting sensor evaluates the cleanliness of the oil by counting the number of particles in the oil and promptly detects potential wear problems; the moisture sensor detects the moisture content in the oil to prevent corrosion and degradation of oil performance caused by excessive moisture.

During the descent process, the monitoring contact 9 passes between the two wiping cottons 16, and the surface of the monitoring contact 9 is wiped and cleaned by the wiping cotton 16, thereby ensuring the accuracy of the monitoring. After the monitoring is completed, the monitoring contact 9 passes through the wiping cotton 16 again during its ascent, and is cleaned a second time by the wiping cotton 16, thereby further ensuring the cleanliness of the surface of the monitoring contact 9. Traditional aircraft oil monitoring devices usually require these sensor probes to be thoroughly cleaned after use to ensure the accuracy and reliability of the next monitoring. This cleaning process traditionally relies on manual wiping. Although this method can remove dirt on the probe to a certain extent, it is time-consuming and labor-intensive. In addition, the manual cleaning process may have consistency problems and the risk of incomplete cleaning, which may have potential impacts on aircraft maintenance and flight safety.

During the descent process, the monitoring contact 9 will pass between two wiping cottons 16, and the wiping cottons 16 will perform the first cleaning of the contact surface to ensure the accuracy of the monitoring. When the contact reaches the appropriate position of the oil, the sensor group starts working to monitor the quality, temperature, pressure, number of particles and moisture content of the oil in real time. After the monitoring is completed, the driving motor 5 is reversed to make the lifting block 7 rise, and the monitoring contact 9 passes through the wiping cotton 16 again for a second cleaning to keep the contact surface clean. After the lifting block 7 rises to the top, the wiping cotton 16 can be easily replaced by opening the box cover 2 to complete the entire monitoring and cleaning process, ensuring the accuracy and reliability of the next monitoring.
