[0049] The present invention will be further described below with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 2 As shown, this utility model provides an oil monitoring device for a fuel engine lubrication hydraulic system, comprising an oil guiding assembly 30, a detection device 40, an electrical control device 50, and a housing structure. The oil guiding assembly 30 has one end connected to the oil inlet of the fuel engine lubrication hydraulic system; the detection device 40 is internally connected to the oil guiding assembly 30 and is used to detect the lubricating oil within the oil guiding assembly 30; the electrical control device 50 is electrically connected to the detection device 40 and can analyze the lubricating oil information detected by the electrical control device 50 to obtain information on the wear condition of the fuel engine; the housing structure has a first mounting cavity and a second mounting cavity. The electrical control device 50 is housed in the first mounting cavity, and the oil guiding assembly 30 and the detection device 40 are housed in the second mounting cavity.

[0051] In the above configuration, a dedicated oil guiding assembly 30 is provided to introduce lubricating oil from the fuel engine's lubrication hydraulic system. The electronic control device 50 is directly connected to the oil guiding assembly 30, allowing the sensor components within the detection device 40 to be centrally located on the oil guiding assembly 30. Furthermore, the oil guiding assembly 30, the detection device 40, and the electronic control device 50 are integrated within the housing structure, achieving a modular design for the oil monitoring device. This makes the oil monitoring device easy to carry, install, and maintain, avoiding the problem of inconvenient centralized maintenance caused by the dispersed components in existing oil monitoring devices. This improves the maintenance and installation efficiency of the oil monitoring device.

[0052] Specifically, such as Figure 1 As shown, in one embodiment, the oil monitoring device further includes a sealing device 60, which is disposed in the second mounting cavity. The connection between the detection device 40 and the oil guiding assembly 30 is located inside the sealing device 60, and the sealing device 60 is used to seal the connection.

[0053] In the above configuration, a sealing device 60 is provided to seal the connection between the detection device 40 and the oil guiding assembly 30, effectively protecting the connection and preventing oil leakage due to external forces or environmental damage. This, in turn, improves the stability and reliability of the oil monitoring device.

[0054] Specifically, such as Figure 3 As shown, in one embodiment, the packaging device 60 includes a base, a housing 61, and a sealing gasket 63. The base is fixed within the housing structure; the housing 61 is disposed on the base; and the sealing gasket 63 is disposed between the base and the housing 61, sealing the gap between them. The base, housing 61, and sealing gasket 63 form a sealed space, and the connection between the detection device 40 and the oil guiding assembly 30 is located within this sealed space.

[0055] In the above configuration, the base, housing 61, and sealing gasket 63 form a sealed space. This places the connection between the detection device 40 and the oil guiding assembly 30 within this space, effectively protecting the connection and preventing oil leakage due to external forces or environmental damage. Ultimately, this improves the stability and reliability of the oil monitoring device.

[0056] Specifically, such as Figure 3 As shown, in one embodiment, the base includes a base plate 62 and a support plate 64 disposed on the base plate 62, the support plate 64 being used to support the oil guiding assembly 30 and the detection device 40.

[0057] Specifically, such as Figure 3 As shown, in one embodiment, a slot 65 is provided on the support plate 64, and the oil guiding assembly 30 is supported in the slot 65.

[0058] Specifically, such as Figure 3 As shown, in one embodiment, there are two support plates 64, which are spaced apart.

[0059] Specifically, such as Figure 3 As shown, in one embodiment, the oil monitoring device further includes a telescopic rod 70, one end of which is fixed inside the housing structure, and the other end of the telescopic rod 70 is a telescopic end, which is connected to the cover 61. The telescopic rod 70 is used to raise and lower the cover 61 along the first direction.

[0060] In the above configuration, the telescopic rod 70 has a guiding function, ensuring that the cover 61 moves up and down in the first direction. This prevents damage to the components inside the cover 61 due to collisions caused by the cover 61 being removed from the base in a direction deviating from the first direction. This, in turn, ensures the proper functioning of the oil monitoring device.

[0061] It should be noted that the telescopic rod 70 is used to raise and lower the cover 61 along the first direction, which facilitates the opening of the encapsulation device 60. This allows staff to easily inspect the internal components, thereby improving the installation and maintenance efficiency of the oil monitoring device.

[0062] Specifically, such as Figure 5 As shown, in one embodiment, the enclosure structure includes an enclosure 10, an enclosure cover 20, and a connecting rod 80. The enclosure 10 has a first mounting cavity and a second mounting cavity inside; the enclosure cover 20 is mounted on the enclosure 10 and pivotally connected to it; one end of the connecting rod 80 is pivotally connected to the enclosure cover 20, and the other end is pivotally connected to a cover 61; when the enclosure cover 20 is flipped open to a preset angle, and the cover 61 moves away from the base along a first direction to a preset moving position, the packaging device 60 is opened.

[0063] In the above configuration, a connecting rod 80 is provided to achieve linkage between the cover 20 and the housing 61. Specifically, when the cover 20 is flipped open to a preset angle, the housing 61 moves away from the base along a first direction to a preset moving position. At this time, the sealing device 60 is opened, facilitating the inspection and maintenance of internal components by personnel. This further improves the installation and maintenance efficiency of the oil monitoring device.

[0064] Specifically, such as Figure 7 As shown, in one embodiment, the telescopic rod 70 includes an outer cylinder 71, a first slider 74, an inner cylinder 72, a second slider 75, and a sliding column 73. The outer cylinder 71 is fixed inside the housing 10; the first slider 74 is slidably disposed inside the outer cylinder 71 along a first direction; the inner cylinder 72 is fixed to the first slider 74; the second slider 75 is slidably disposed inside the inner cylinder 72 along the first direction; and the sliding column 73 has one end disposed on the second slider 75 and the other end connected to the cover 61.

[0065] In the above configuration, the telescopic rod 70 is configured as a two-section telescopic bushing structure, which is used to realize its guiding function.

[0066] Of course, in alternative embodiments not shown in this application, the telescopic rod 70 can be an electrically operated telescopic rod. When an electrically operated telescopic rod is used, the cover 20 and the housing 61 do not need to be linked.

[0067] Specifically, such as Figure 6 As shown, in one embodiment, a sealing ring 21 is provided at the connection between the box body 10 and the box cover 20. The sealing ring 21 is used to seal the gap between the box body 10 and the box cover 20.

[0068] Specifically, such as Figure 6 As shown, in one embodiment, a screw 22 is provided on the cover 20, and a threaded hole corresponding to the screw 22 is provided on the body 10. The screw 22 rotates in the threaded hole, and the screw 22 is used to fix the cover 20 to the body 10.

[0069] Specifically, such as Figure 4 As shown, in one embodiment, the oil guiding assembly 30 includes an oil inlet pipe 31, a connecting pipe 32, and a detection pipe 33. The oil inlet pipe 31 is connected at one end to the oil inlet of the fuel engine lubrication hydraulic system; the connecting pipe 32 is connected at one end to the other end of the oil inlet pipe 31; and the detection pipe 33 is connected at one end to the other end of the connecting pipe 32. The oil inlet pipe 31, the connecting pipe 32, and the detection pipe 33 are separate structures, and the detection pipe 33 is connected to the detection device 40.

[0070] Specifically, in one embodiment, the detection device 40 includes a metal wear particle sensor, a temperature sensor, a moisture sensor, a viscosity measurement sensor, a density measurement sensor, a conductivity measurement sensor, and a dielectric constant measurement sensor.

[0071] The following is combined with Figures 1 to 8 Here is a more specific embodiment of this application:

[0072] This utility model provides an oil monitoring component for a fuel engine lubrication hydraulic system, including a housing 10, a housing cover 20, screws 22, a detection device 40, and an electrical control device 50. The housing cover 20 is rotatably mounted on one side of the housing 10, and screws 22 that are threadedly connected to the housing 10 are symmetrically mounted on the bottom end of the housing cover 20. The electrical control device 50 is installed inside the housing 10 and is electrically connected to the detection device 40. An oil guiding assembly 30 is installed inside the housing 10 below the detection device 40, and the detection device 40 is fixedly connected to the oil guiding assembly 30. An encapsulation device 60 is provided inside the housing 10 outside the oil guiding assembly 30. A telescopic rod 70 is symmetrically fixed on the top surface inside the housing 10, and the telescopic end of the telescopic rod 70 is fixedly connected to the encapsulation device 60. A connecting rod 80 is rotatably mounted on the inner wall of the housing cover 20 and is rotatably connected to the encapsulation device 60.

[0073] When the testing equipment 40 is working, it is sealed by the packaging equipment 60 to isolate the testing equipment 40 from the working environment and prevent the testing equipment 40 from malfunctioning due to the harsh working environment. The convenient switch of the cover 20 is used for equipment maintenance. When the cover 20 is opened, the packaging equipment 60 is lifted and opened by the linkage of the connecting rod 80, which facilitates the maintenance of the testing parts.

[0074] The electrical control equipment of Institute 50 is a combination of power supply equipment, analysis and transmission equipment, and its principle is the same as that of existing detection and control equipment.

[0075] The lubrication system of the fuel engine is connected to the oil guide assembly 30. As the oil passes through the oil guide assembly 30, its characteristics are detected by the detection device 40. The wear condition of the equipment is then assessed by the electronic control device 50. The detection device 40 employs various sensors, including the following:

[0076] Metal wear particle sensor: The working principle of the metal wear particle sensor is to attract metal abrasive particles to the surface of the sensor, which can detect the content of solid particles in the lubricating oil.

[0077] Temperature sensor: It can sense temperature and convert it into a usable output signal for real-time detection of lubricating oil temperature;

[0078] Moisture sensor: It can monitor free water and emulsified water in oil in real time, continuously and accurately, and provide 360° all-round real-time online moisture monitoring of oil, which is used to detect the water content in lubricating oil;

[0079] Viscosity and density measurement sensors: These employ resonant liquid density sensors. The principle is that an elastic sensing element in the system comes into contact with the liquid phase, thereby changing the equivalent mass of the system and altering its natural frequency. By measuring the change in this fixed frequency, the density of the liquid is determined, making it suitable for detecting the viscosity and density of lubricating oils.

[0080] Conductivity and dielectric constant measurement sensors: Their unique sensing structure makes them extremely sensitive to changes in oil quality, enabling them to react to changes in oil condition in real time, continuously and rapidly. They can detect the state of oil such as acid value, wear particles, moisture, mechanical impurities, and additive cracking.

[0081] It should be noted that the existing overall technical specifications for testing are as follows:

The sealing gasket 63 is fixed on the surface of the base plate 62 at a corresponding position on the cover 61. The connecting rod 80 is rotatably connected to the outer wall of the cover 61. The sealing of the detection part is achieved by the fit between the cover 61 and the base plate 62. The setting of the sealing gasket 63 ensures that the cover 61 and the base plate 62 fit tightly, avoiding damage to the detection part by the working environment. The lifting and lowering of the cover 61 facilitates the maintenance of the detection part.

[0101] like Figure 3As shown, the base plate 62 is symmetrically fixed with support plates 64, and the support plates 64 are fixedly connected to the detection tube 33. The bottom surface of the cover 61 is provided with slots 65 that cooperate with the support plates 64. The fit and sealing between the cover 61 and the base plate 62 are increased by engaging the slots 65 with the support plates 64.

[0102] like Figure 8 As shown, the sealing gasket 63 has a corrugated cross-section, and hollow grooves are evenly spaced inside the sealing gasket 63 to improve the sealing performance between the cover 61 and the base plate 62. Both the base plate 62 and the cover 61 are made of stainless steel, providing good corrosion resistance.

[0103] like Figure 6 As shown, a sealing ring 21 is fixedly bonded to the inner edge of the box cover 20 to increase the sealing performance of the box cover 20 and the box body 10.
