[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

[0034] See also Figure 1-Figure 8 In one embodiment of the present application, an intelligent online oil monitoring device includes a monitoring box 1, a controller 3 and a liquid inlet 5, wherein the controller 3 is arranged on the monitoring box 1, and the liquid inlet 5 is arranged on the monitoring box 1. The online monitoring device also includes a top box 7, a monitoring inner box 12, a monitoring component and a flushing component. The top box 7 is arranged on the monitoring box 1, and the monitoring inner box 12 is arranged in the top box 7. The monitoring component is arranged in the monitoring inner box 12, and is used to perform online monitoring of the lubricating oil passing through the monitoring box 1. The flushing component is arranged on the monitoring box 1 and is connected to the monitoring inner box 12, and is used to clean the monitoring component.

[0035] The monitoring assembly includes a plurality of monitoring heads 15, mounting parts, measuring channels 21, a positioning structure and a sealing structure. The monitoring inner box 12 is provided with a plurality of measuring channels 21 in an inner ring, and a mounting part is movably provided in each measuring channel 21. The monitoring head 15 is provided on the mounting part. The monitoring box 1 is provided with a monitoring hole 10 matched with the monitoring head 15. The positioning structure is provided between the top box 7 and the monitoring inner box 12 and is connected to the mounting part, and is used to adjust the position of the mounting part and the monitoring head 15 in the measuring channel 21. The sealing structure is provided on the monitoring inner box 12 and is connected to the positioning structure. When the positioning structure is working, it controls the sealing structure to work synchronously and seals the measuring channel 21.

[0036] In a specific case of this embodiment, the mounting component includes a monitoring mounting block 25 and a card block. The monitoring mounting block 25 is movably arranged in the measuring channel 21. The card blocks are in a group and are symmetrically arranged on the monitoring mounting block 25. A card groove that slides with the card block is formed in the measuring channel 21, and the monitoring head 15 is installed in the mounting groove formed on the monitoring mounting block 25.

[0037] In another specific case of the present embodiment, the positioning structure includes a first threaded rod 18, a mounting seat 17, a first gear 19, a power element and a toothed adjustment disk. The first threaded rod 18 is installed on the monitoring inner box 12 through the mounting seat 17. The first threaded rod 18 is connected to the monitoring mounting block 25 and the two are threadedly matched. The first gear 19 is sleeved on the end of the first threaded rod 18 away from the monitoring mounting block 25. The toothed adjustment disk is movably arranged in the top box 7. A plurality of teeth are equidistantly arranged on the toothed adjustment disk. The teeth are matched with the first gear 19. The first gear 19 is located on the moving path of the teeth. The power element is arranged on the top box 7 and its output end is connected to the toothed adjustment disk.

[0038] In this embodiment, the power element can be a stepper motor 6 or a servo motor. In this embodiment, the power element is preferably a stepper motor 6. The stepper motor 6 is arranged on the top box 7 and its output end is connected to the toothed adjustment disk. As for the specific model parameters of the stepper motor 6, the best choice can be made according to the actual situation, and no specific limitation is made here.

[0039] In actual application, by installing the monitoring box 1 on the steam turbine and connecting the lubricating oil system of the steam turbine with the liquid inlet 5, the monitoring head 15 can be used to perform online monitoring of various data of the lubricating oil, such as viscosity, moisture, contamination and wear particle count; the controller 3 controls the stepper motor 6 to rotate slowly, driving the toothed adjustment disk to rotate synchronously. Since a number of teeth are equidistantly arranged on the toothed adjustment disk, the teeth can successively meet the first gear 19 at different positions, thereby driving the first gear 19 and the first threaded rod 18 to rotate. Under the action of the threaded cooperation between the first threaded rod 18 and the monitoring mounting block 25, the monitoring head 15 can be controlled to move up and disengage from the monitoring box 1. When the monitoring head 15 completely enters the measuring channel 21, the sealing structure is controlled to perform sealing treatment between the measuring channel 21 and the monitoring box 1; the flushing component is automatically controlled by the controller 3, so that water flow can be input into the measuring channel 21, so that the monitoring heads 15 at different positions can be flushed in sequence.

[0040] See also Figure 1-Figure 6As another preferred embodiment of the present application, the sealing structure includes an adjusting disk 20, a sealing plate 22, a magnetic block 24 and a trigger member. The adjusting disk 20 is movably arranged on the monitoring inner box 12 and is coaxially connected to the toothed adjusting disk. The number of the sealing plates 22 is several and they are arranged in a ring on the monitoring inner box 12. The sealing plate 22 is movably arranged in the measuring channel 21 and the two are elastically connected. The magnetic block 24 is arranged between the sealing plate 22 and the adjusting disk. When the adjusting disk rotates, the position of the sealing plate 22 is adjusted by the magnetic block 24. The trigger member is arranged between the sealing plate 22 and the monitoring inner box 12 for monitoring the position of the sealing plate 22. The trigger member controls the flushing component to input water into the measuring channel 21.

[0041] In a specific case of this embodiment, the magnetic block 24 includes a No. 1 magnet and a No. 2 magnet. The No. 1 magnet is arranged at an eccentric position of the adjusting disk. There are several No. 2 magnets. Each of the sealing plates 22 is provided with a No. 2 magnet. The No. 1 magnet and the No. 2 magnet repel each other when they meet.

[0042] In another specific case of this embodiment, the trigger member includes a group of conductive blocks 23, and the blocking plate 22 and the monitoring inner box 12 are both provided with conductive blocks 23, and the conductive blocks 23 are electrically connected to the flushing assembly.

[0043] It should be noted that the present embodiment is not limited to a group of conductive blocks 23 to detect the position of the blocking plate 22, and an infrared distance measuring sensor or a laser distance measuring sensor may also be directly used instead, which are not listed here one by one.

[0044] When the stepper motor 6 is powered on and rotated, it can drive the adjustment disk 20 to rotate synchronously. The adjustment disk 20 can drive the No. 1 magnet to rotate and meet and repel the No. 2 magnet at a different position, so that the sealing plates 22 at different positions can be pushed into the measuring channel 21 in succession to perform the sealing work between the measuring channel 21 and the monitoring box 1, and when the sealing plate 22 completely enters the measuring channel 21, the two conductive blocks 23 can meet and contact each other, thereby starting the flushing component to work and injecting clean water into the measuring channel 21 where the monitoring head 15 that moves upward is located, thereby achieving the flushing work of the monitoring heads 15 at different positions.

[0045] See also Figure 1-Figure 8As another preferred embodiment of the present application, the flushing assembly includes a rotor, a water tank 2, a piston 26, a water inlet 4, a drain 32 and a transmission member. The water tank 2 is arranged on the monitoring box 1, and the water tank 2 is provided with a water inlet 4 and a drain 32. Both the water inlet 4 and the drain 32 are provided with a one-way valve. The piston 26 is movably arranged in the water tank 2 and the two are elastically connected. The rotor is movably arranged in the monitoring box 1. The transmission member is arranged on the monitoring box 1 and connected to the rotor. When the rotor rotates, the transmission member is controlled to work and adjust the position of the piston 26 in the water tank 2. The drain 32 is connected to each of the measuring channels 21, and a plurality of sewage outlets 16 connected to the measuring channels 21 are arranged on the top box 7.

[0046] In a specific case of the present embodiment, the transmission member includes a driving missing gear 29, a second threaded rod 28, a screw sleeve 27, a second gear 31 and a missing tooth portion 30. The driving missing gear 29 is movably arranged in the water tank 2 and is coaxially connected to the rotating blade. The missing tooth portion 30 is arranged on the driving missing gear 29. The second gear 31 is movably arranged on the monitoring box 1 and a torsion spring is arranged between the two. The second threaded rod 28 is movably arranged in the water tank 2 and is coaxially connected to the second gear 31. The screw sleeve 27 is arranged on the piston 26. The second threaded rod 28 is movably inserted in the screw sleeve 27 and the two are threadedly matched.

[0047] In another specific case in the present embodiment, a water inlet hole 13 and a drain hole 14 connected to the measuring channel 21 are formed on the monitoring inner box 12, and the drain hole 14 is connected to the sewage outlet 16. A water inlet ring box 8 is provided on the top box 7, and the water inlet ring box 8 is connected to the drain outlet 32. A solenoid valve 9 is provided between the water inlet ring box 8 and the water inlet hole 13, and the solenoid valve 9 is electrically connected to the conductive block 23.

[0048] When the lubricating oil passes through the monitoring box 1, the driving vane 11 can be controlled to rotate under the friction between the lubricating oil and the driving vane 11, thereby driving the driving gear 29 to rotate. Under the meshing action between the driving gear 29 and the second gear 31, the second gear 31 can be driven to rotate. At this time, the torsion spring stores energy and drives the second threaded rod 28 to rotate. Under the threaded cooperation between the second threaded rod 28 and the screw sleeve 27, the piston 26 can be driven as shown in FIG. Figure 8When the toothed portion 30 of the driving gear 29 meets the second gear 31, the torsion spring can reverse the second gear 31 and the second threaded rod 28. The blocking plate 22 corresponding to the monitoring head 15 in the upward position is displaced, causing the conductive blocks 23 to contact each other, thereby controlling the solenoid valve 9 connected to the measuring channel 21 to open, so that the piston 26 moves downward and resets, and squeezes the water into the water inlet ring box 8 along the drain port 32, and finally enters the measuring channel 21 along the water inlet hole 13, and finally is discharged from the sewage outlet 16 along the drain hole 14, thereby realizing the flushing of the upwardly moved monitoring head 15.

[0049] See also Figure 1-Figure 8 In another embodiment of the present application, an intelligent oil online monitoring method is applied to the online monitoring device described in the above embodiment, and the specific steps of the online monitoring method are as follows:

[0050] S100: By installing the monitoring box 1 on the steam turbine and connecting the lubricating oil system of the steam turbine to the liquid inlet 5, the monitoring head 15 can be used to perform online monitoring of various data of the lubricating oil, such as viscosity, moisture, contamination and wear particle count;

[0051] S200: By controlling the adjustment structure to work, under a set period, the installation parts and the monitoring head 15 at different positions are intermittently controlled to move upward along the measuring channel 21, so that the monitoring head 15 is separated from the lubricating oil, and at this time, the sealing structure works to isolate the measuring channel 21 and the monitoring box 1;

[0052] S300: The flushing component is automatically controlled by the controller 3 to input water into the measuring channel 21, so that the monitoring heads 15 at different positions can be flushed in sequence.
