Description

Technical Field

[0001] The present invention belongs to the technical field of oil fluid monitoring, and specifically relates to an oil fluid monitoring device and method for multi-sensor data fusion. Background Art

[0002] Oil fluid is an important lubricating substance for equipment such as internal combustion engines, and it is stored in the oil fluid storage mechanism of the internal combustion engine. At present, for the oil fluid of internal combustion engines, the basic methods are "observing oil change" or "changing oil according to schedule", determining the oil change time by empirical observation and subjective judgment or according to the service life of the lubricating oil;

[0003] In the prior art found through retrieval, a Chinese patent with the publication number CN115389744A discloses an oil fluid monitoring device for multi-sensor data fusion. The first flexible traction member and the second flexible traction member cooperate to pull in different directions to limit the electromagnetic shielding housing. A tension sensor is provided on the second flexible traction member to monitor the change in tension and calculate the density of the oil fluid;

[0004] However, it is worth considering that when the internal combustion engine is installed on a vehicle, since the first flexible traction member and the second flexible traction member are made of flexible materials, although it avoids the monitoring housing from floating out of the oil fluid, when the vehicle running speed changes greatly, the monitoring housing will shake in the oil fluid, and the monitoring housing may directly impact the inner wall of the oil fluid storage mechanism, thereby causing damage to the monitoring components inside the monitoring housing. During the shaking process of the monitoring housing, the second flexible traction member will also repeatedly pull the tension sensor, and over time, it is also easy to cause the tension sensor to malfunction.

Finally, the four support plates 5 support the support ring 3, so that the support ring 3 and the monitoring device body 1 are fixed relative to the support box 2.

At this time, the upward forces on the support ring 3 and the monitoring device body 1 are monitored by the tensile force monitoring unit, so as to monitor the change of the oil fluid density. When it is not necessary to monitor the density of the oil fluid, the shaking of the monitoring device body 1 in the oil fluid can be avoided, and no tensile force is applied to the tensile force monitoring unit, thus avoiding affecting the tensile force monitoring unit. By driving the monitoring device body 1 to rotate relative to the support ring 3 through the rotation adjustment component, the position of the oil fluid entering the pipeline on the monitoring device body 1 can be changed, which is convenient for monitoring the oil fluid at different positions in the oil fluid storage mechanism and improves the accuracy of monitoring.

[0039] The first bevel gear 20 is driven to rotate by the servo motor 19. The first bevel gear 20 drives the first rotating shaft 15 and the first damping disc 16 to rotate through the second bevel gear 21. The first damping disc 16 can drive the second damping disc 17 and the first connecting shaft 14 to rotate synchronously through friction. The first connecting shaft 14 drives the two toothed plates 12 to move in opposite directions through the gear 13, so that the two iron frames 8 move closer to each other. The iron frame 8 can pull the first traction rope 6 to move, so that the support ring 3 contacts the elastic pad 24 on the support plate 5. The support ring 3 is fixed relative to the oil storage mechanism, preventing the monitoring device body 1 from shaking in the oil. At this time, the electromagnet 11 contacts the iron frame 8. When it is necessary to monitor the density of the oil, the first bevel gear 20 is driven to rotate in the reverse direction by the servo motor 19, so that the first traction rope 6 moves in the reverse direction. When the support ring 3 and the monitoring device body 1 move up to the preset height, the first traction rope 6 is in a loose state and the second traction rope 23 is in a taut state. The tension sensor 22 can monitor the upward force received by the support ring 3 and the monitoring device body 1, thereby monitoring the change in the oil density.

[0040] Embodiment 3, on the basis of Embodiment 2, by Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7Given that the rotation adjustment assembly includes two positioning rings 25 fixedly sleeved outside the monitoring device body 1. A chute 26 is formed on the inner wall of the support ring 3, and the positioning ring 25 is located in the chute 26. The two support rings 3 are fixedly connected by a support seat 27. A fixed shell 28 is fixedly connected to the support seat 27. A second rotating shaft 29 is rotatably connected to the fixed shell 28. Damping rollers 30 are fixedly connected to both ends of the second rotating shaft 29, and the damping rollers 30 are in contact with the outer wall of the monitoring device body 1. A second connecting shaft 31 is rotatably connected to the fixed shell 28. A third damping plate 32 is fixedly connected to the bottom end of the second connecting shaft 31. A third bevel gear 33 located inside the fixed shell 28 is fixedly connected to the top end of the second connecting shaft 31. A fourth bevel gear 34 located inside the fixed shell 28 is fixedly sleeved outside the second rotating shaft 29, and the fourth bevel gear 34 meshes with the third bevel gear 33. A fourth damping plate 41 located above the protection box 18 is fixedly connected to the top end of the first rotating shaft 15, and the top of the fourth damping plate 41 is in contact with the bottom of the third damping plate 32. The locking mechanism includes at least two fixing plates 35 fixedly installed in the support box 2. An insertion plate 36 penetrates through the fixing plate 35. At least two insertion holes 37 are formed on the inner wall of the installation box 7, and the number of the insertion holes 37 is the same as that of the insertion plates 36. One end of the insertion plate 36 is located in the corresponding insertion hole 37. A movable plate 39 is fixedly connected to the other end of the insertion plate 36. The movable plate 39 and the fixing plate 35 are connected by a tension spring 40. A second support plate 38 is fixedly sleeved outside the insertion plate 36, and the second support plate 38 is located on the side of the fixing plate 35 away from the movable plate 39;

[0041] When the support ring 3 and the monitoring device body 1 descend to the lowest position relative to the support box 2, the bottom of the third damping disc 32 contacts the top of the fourth damping disc 41. When it is necessary to drive the monitoring device body 1 to rotate relative to the support ring 3 to change the position of the oil inlet pipe on the monitoring device body 1, the electromagnet 11 is started. The electromagnet 11 applies a magnetic force to the iron frame 8 to fix the iron frame 8 and the toothed plate 12 relative to the support box 2. At this time, the second damping disc 17 is fixed relative to the support box 2. The first bevel gear 20 is driven to rotate by the servo motor 19. The first bevel gear 20 drives the first rotating shaft 15 and the first damping disc 16 to rotate through the second bevel gear 21. The first damping disc 16 cannot drive the second damping disc 17 to rotate synchronously through friction. And at this time, the first rotating shaft 15 drives the fourth damping disc 41 to rotate. The fourth damping disc 41 can drive the third damping disc 32 and the second connecting shaft 31 to rotate through friction. The second connecting shaft 31 drives the fourth bevel gear 34, the second rotating shaft 29 and the damping roller 30 to rotate through the third bevel gear 33. The damping roller 30 can drive the monitoring device body 1 to rotate relative to the support ring 3 through friction. When it is necessary to drive the support ring 3 and the monitoring device body 1 to move upward relative to the support box 2, the electromagnet 11 is turned off, and the electromagnet 11 no longer applies a magnetic force to the iron frame 8. When the first damping disc 16 rotates, the first damping disc 16 can drive the first connecting shaft 14 to rotate again through the second damping disc 17, so that the first towing rope 6 moves in the reverse direction, and the support ring 3 and the monitoring device body 1 can move upward relative to the support box 2. The third damping disc 32 no longer contacts the fourth damping disc 41. When it is necessary to remove the support box 2 from the installation box 7, the staff pushes the insertion plate 36 to move, so that the insertion plate 36 disengages from the insertion hole 37, and the insertion plate 36 drives the second support plate 38 and the movable plate 39 to move. The tension spring 40 is in a stretched state. When the insertion plate 36 completely disengages from the insertion hole 37, the second support plate 38 contacts the fixed plate 35. The staff drives the support box 2 to move upward to pull the support box 2 out of the installation box 7, and the disassembly between the support box 2 and the installation box 7 can be completed, which is convenient for removing the monitoring device body 1 and the support ring 3 from the oil storage mechanism.

[0042] A method for monitoring oil using multi-sensor data fusion according to this embodiment uses the multi-sensor data fusion oil monitoring device as described above, and includes the following steps:

[0043] Step 1: The staff fixedly installs the installation box 7 in the oil storage mechanism of the internal combustion engine;

[0044] Step 2: When it is not necessary to monitor the density of the oil, the first towing rope 6 is driven to move through the tightening structure. The first towing rope 6 pulls the support ring 3 towards the support plate 5, and finally the four support plates 5 support the support ring 3;

[0045] Step 3: When it is necessary to monitor the density of the oil fluid, drive the first towing rope 6 to move in the reverse direction through the tightening structure, the monitoring device body 1 moves upward, and the first towing rope 6 is in a loose state. At this time, the upward forces received by the support ring 3 and the monitoring device body 1 are monitored through the tensile force monitoring unit, so as to monitor the change in the density of the oil fluid;

[0046] Step 4: Drive the monitoring device body 1 to rotate relative to the support ring 3 through the rotation adjustment assembly, change the position of the oil fluid entering the pipeline on the monitoring device body 1, and monitor the oil fluid at different positions in the oil fluid storage mechanism through the monitoring device body 1.

[0047] Working principle: The staff fixedly installs the installation box 7 in the oil fluid storage mechanism of the internal combustion engine. When it is not necessary to monitor the density of the oil fluid, drive the first towing rope 6 to move through the tightening structure. The first towing rope 6 slides relative to the first support plate 4 and the support plate 5. The first towing rope 6 pulls the support ring 3 to move towards the support plate 5. Finally, the four support plates 5 support the support ring 3, so that the support ring 3 and the monitoring device body 1 are fixed relative to the support box 2. When it is necessary to monitor the density of the oil fluid, drive the first towing rope 6 to move in the reverse direction through the tightening structure, the monitoring device body 1 moves upward, and the first towing rope 6 is in a loose state. At this time, the upward forces received by the support ring 3 and the monitoring device body 1 are monitored through the tensile force monitoring unit, so as to monitor the change in the density of the oil fluid. When it is not necessary to monitor the density of the oil fluid, it is possible to prevent the monitoring device body 1 from shaking in the oil fluid, and no tensile force is applied to the tensile force monitoring unit, avoiding affecting the tensile force monitoring unit. By driving the monitoring device body 1 to rotate relative to the support ring 3 through the rotation adjustment assembly, the position of the oil fluid entering the pipeline on the monitoring device body 1 can be changed, facilitating the monitoring of the oil fluid at different positions in the oil fluid storage mechanism and improving the accuracy of monitoring;

[0048] Drive the first bevel gear 20 to rotate through the servo motor 19. The first bevel gear 20 drives the first rotating shaft 15 and the first damping disc 16 to rotate through the second bevel gear 21. The first damping disc 16 can drive the second damping disc 17 and the first connecting shaft 14 to rotate synchronously through friction. The first connecting shaft 14 drives the two toothed plates 12 to move in opposite directions through the gear 13, so that the two iron frames 8 move closer to each other. The iron frame 8 can pull the first towing rope 6 to move, so that the support ring 3 contacts the elastic pad 24 on the support plate 5, and the support ring 3 is fixed relative to the oil fluid storage mechanism, preventing the monitoring device body 1 from shaking in the oil fluid. And at this time, the electromagnet 11 contacts the iron frame 8. When it is necessary to monitor the density of the oil fluid, drive the first bevel gear 20 to rotate in the reverse direction through the servo motor 19, so that the first towing rope 6 moves in the reverse direction. When the support ring 3 and the monitoring device body 1 move upward to the preset height, the first towing rope 6 is in a loose state, and the second towing rope 23 is in a taut state. The tensile force sensor 22 can monitor the upward forces received by the support ring 3 and the monitoring device body 1, so as to monitor the change in the density of the oil fluid;

[0049] When the support ring 3 and the monitoring device body 1 descend to the lowest position relative to the support box 2, the bottom of the third damping disc 32 contacts the top of the fourth damping disc 41. When it is necessary to drive the monitoring device body 1 to rotate relative to the support ring 3 to change the position of the oil inlet pipe on the monitoring device body 1, the electromagnet 11 is started. The electromagnet 11 exerts a magnetic force on the iron frame 8 to fix the iron frame 8 and the toothed plate 12 relative to the support box 2. At this time, the second damping disc 17 is fixed relative to the support box 2. The first bevel gear 20 is driven to rotate by the servo motor 19. The first bevel gear 20 drives the first rotating shaft 15 and the first damping disc 16 to rotate through the second bevel gear 21. The first damping disc 16 cannot drive the second damping disc 17 to rotate synchronously through friction. And at this time, the first rotating shaft 15 drives the fourth damping disc 41 to rotate. The fourth damping disc 41 can drive the third damping disc 32 and the second connecting shaft 31 to rotate through friction. The second connecting shaft 31 drives the fourth bevel gear 34, the second rotating shaft 29 and the damping roller 30 to rotate through the third bevel gear 33. The damping roller 30 can drive the monitoring device body 1 to rotate relative to the support ring 3 through friction. The monitoring device body 1 drives the positioning ring 25 to slide relative to the sliding groove 26. When it is necessary to drive the support ring 3 and the monitoring device body 1 to move upward relative to the support box 2, the electromagnet 11 is turned off, and the electromagnet 11 no longer exerts a magnetic force on the iron frame 8. When the first damping disc 16 rotates, the first damping disc 16 can drive the first connecting shaft 14 to rotate again through the second damping disc 17, so that the first traction rope 6 moves in the reverse direction. The support ring 3 and the monitoring device body 1 can move upward relative to the support box 2, and the third damping disc 32 no longer contacts the fourth damping disc 41. When it is necessary to remove the support box 2 from the installation box 7, the staff pushes the insertion plate 36 to move, so that the insertion plate 36 disengages from the insertion hole 37, and the insertion plate 36 drives the second support plate 38 and the movable plate 39 to move. The tension spring 40 is in a stretched state. When the insertion plate 36 completely disengages from the insertion hole 37, the second support plate 38 contacts the fixed plate 35. The staff drives the support box 2 to move upward to pull the support box 2 out of the installation box 7, and the disassembly between the support box 2 and the installation box 7 can be completed, which is convenient for removing the monitoring device body 1 and the support ring 3 from the oil storage mechanism.
