[0002] During the operation of modern industrial equipment, the condition of the lubricant directly impacts its performance and lifespan. Lubricants' primary functions are to reduce friction, minimize wear, cool the equipment, and prevent corrosion. Therefore, real-time monitoring of lubricants is a key means of ensuring stable equipment operation. Traditional lubricant monitoring methods rely on periodic sampling and laboratory analysis. This approach is not only time-consuming and labor-intensive, but also fails to provide real-time data on equipment operation. This can lead to untimely reflection of equipment operating status and increases the risk of potential equipment damage.
[0003] Although the existing lubricating oil monitoring device has achieved online monitoring to a certain extent, it still has some shortcomings:
[0004] Insufficient sample representativeness: Many existing devices extract lubricant oil at only a single location, resulting in poor sample representativeness and difficulty fully reflecting the true condition of the entire lubrication system. This limitation may lead to biased test results and affect the accuracy of judgments.
[0005] Low sampling efficiency: Existing devices lack precise control over the sampling volume, resulting in low efficiency and accuracy in sample collection. Some equipment is prone to lubricant leakage during sampling, which not only wastes resources but also may cause equipment contamination.
[0006] Poor compatibility: The design of some devices fails to take into account compatibility with other equipment or systems. The connections are complex and loose, which can easily cause leakage problems at the pipe connections, affecting the stability and reliability of the entire lubrication system. Utility Model Content

[0038] See also Figure 1-4 , a lubricating oil monitoring device, including a lubricating oil guide pipe 1. The main function of the lubricating oil guide pipe 1 is to guide the lubricating oil out of the equipment through the internal flow channel for subsequent testing. An upper docking seat 6 is installed on the top tube wall of the lubricating oil guide pipe 1, and the upper docking seat 6 and the guide pipe 1 are fixed by welding. The lower end of the lubricating oil guide pipe 1 is docked with a lower docking seat 2 through the upper docking seat 6. The upper end face of the lower docking seat 2 is provided with an arc surface that fits with the bottom tube wall of the lubricating oil guide pipe 1. Four liquid extraction nozzles 3 are installed in sequence from left to right at the center of the top arc surface of the lower docking seat 2. The setting of these liquid extraction nozzles 3 helps to extract lubricating oil samples at different positions or at different times to ensure the representativeness and accuracy of the samples. The top ends of the four liquid extraction nozzles 3 are respectively plugged into the four docking sockets 12 set at the bottom of the lubricating oil guide pipe 1. The interior of the lower docking seat 2 is set as a cavity, and four sampling components 4 are sequentially plugged into the interior of the cavity.
[0039] Example 2
[0040] The present invention further provides a specific structure of a sampling component 4. The sampling component 4 is the core functional component of the monitoring device, and is mainly responsible for the collection and preliminary testing of lubricating oil samples. The sampling component 4 includes a sampling box 41 that is inserted into the bottom end of the lower docking seat 2. A piston 43 is slidably engaged inside the sampling box 41. The piston 43 is manufactured through precision machining, and its surface is smooth and has good sealing properties, which can effectively prevent lubricating oil leakage. The function of the piston 43 is to change the volume inside the sampling box 41 by moving up and down, thereby controlling the amount of lubricating oil extracted. An exhaust air pump 42 is installed at the center position of the bottom of the sampling box 41. The exhaust air pump 42 is used to create a pressure difference between the inside and outside of the sampling box 41, thereby realizing the up and down sliding control of the piston 43, so as to facilitate the extraction of lubricating oil into the sampling box 41. A liquid guide hole 44 is provided at the top of the sampling box 41. The liquid guide hole 44 is connected to the liquid extraction nozzle 3 at this position. The setting of the liquid guide hole 44 enables smooth transmission of lubricating oil between the sampling box 41 and the liquid extraction nozzle 3.
[0041] Example 3
[0042] On the basis of Example 2, in order to improve the stability of the piston 43 sliding inside the sampling box 41, vertically distributed guide posts 45 are provided on both the left and right sides of the sampling box 41. The guide posts 45 are made of high-strength material and can maintain good rigidity under high-pressure environments. The guide posts 45 on both sides are respectively connected to the left and right ends of the piston 43. The guide posts 45 not only play a guiding role, but also can withstand the lateral force generated by the piston 43 during movement, thereby preventing the piston 43 from tilting or deflecting during the sliding process. This design can significantly improve the smoothness of the movement of the piston 43, thereby ensuring a more accurate amount of lubricating oil extracted, thereby improving the accuracy and reliability of the detection.
[0043] Example 4
[0044] To ensure accurate and secure docking between the upper docking station 6 and the lower docking station 2, the present invention provides several foolproof plug-in posts 61 at the bottom of the front and rear edges of the upper docking station 6. These foolproof plug-in posts 61 are rationally distributed to ensure that the upper and lower docking stations 6 and 2 do not align in the wrong direction when splicing. Several foolproof plug-in holes 21 are provided at the front and rear edges of the top of the lower docking station 2. The positions of these plug-in holes 21 correspond one-to-one with the plug-in posts 61. Through the tight fit between the plug-in posts 61 and the plug-in holes 21, accurate positioning between the upper docking station 6 and the lower docking station 2 is achieved. The foolproof plug-in design greatly reduces the probability of error during assembly and improves the assembly efficiency and reliability of the device.
[0045] Example 5
[0046] To further secure the upper docking seat 6 and the lower docking seat 2, the front and rear ends of the joint are secured by docking clips 13. This ensures a tight fit between the upper and lower docking seats while also facilitating disassembly and maintenance. Once the upper and lower docking seats are aligned, the operator simply presses the clip for quick and reliable locking. The design of docking clips 13 not only enhances structural stability but also facilitates subsequent maintenance and overhaul, extending the lifespan and safety of the device.
[0047] Example 6
[0048] To protect the inspection assembly 4 at the bottom of the lower docking station 2, the present invention installs a docking cover 5 at the bottom end of the lower docking station 2. Made of dust- and moisture-proof materials, the docking cover 5 effectively isolates the inspection assembly 4 from the external environment. Especially during equipment downtime or maintenance, the docking cover 5 prevents impurities such as dust and moisture from entering the inspection assembly 4, preventing secondary contamination. Furthermore, the docking cover 5 offers a certain degree of impact resistance, protecting internal components from external impacts and extending the device's service life.
[0049] Example 7
[0050] In this utility model, to facilitate connection with other equipment, docking flanges 11 are installed at both the front and rear ends of the lubricating oil pipe 1. These docking flanges 11 utilize a standardized design and are compatible with various existing lubricating oil piping systems. Bolted together, they ensure a tight and secure connection. These docking flanges not only facilitate installation and removal of the device but also withstand certain variations in pipeline pressure and temperature, ensuring stable operation of the entire lubricating oil monitoring device under various operating conditions.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
