Description

Technical Field

[0001] This utility model belongs to the field of oil condition monitoring technology, and in particular relates to a fan oil condition monitoring device. Background Technology

[0002] Wind turbine gear sets are usually in complex and variable working environments, such as extreme cold and sandstorms, which may cause the oil to become contaminated or deteriorate. Therefore, monitoring the oil helps to detect and solve these problems in a timely manner and ensure the normal operation of the gear set.

[0003] Secondly, the condition and performance of the oil directly affect the lubrication effect and lifespan of the gear set. By monitoring various parameters of the oil, such as viscosity, moisture content, acid value, and particulate contamination, the quality and usage condition of the oil can be assessed, thereby determining whether there are potential risks of gear set failure.

[0004] In practical applications, when the wind turbine gear set needs to unload oil or have old oil replaced, the oil flows out from a specific unloading port. During this process, the flowing oil can be monitored in real time to assess the quality and condition of the oil within the gear set. However, a common problem is that the oil often carries impurities and particles as it flows through the pipes. These impurities and particles gradually accumulate in the pipes, and once they reach a certain level, they can severely affect the smooth flow of the oil, even causing complete blockage. While existing wind turbine oil condition monitoring devices can monitor the oil's condition, they often lack effective methods for clearing blockages, making accurate sampling and testing of the oil in the pipes impossible.

[0005] In view of the problems existing in the prior art, this utility model provides a fan oil condition monitoring device, which has the advantage of being able to unclog blocked pipes and solves the problems existing in the prior art.

[0006] This utility model is implemented as follows: a fan oil condition monitoring device includes a sampling tube, a first cavity is opened in the sampling tube, a physical analysis component is installed in the first cavity, a light source component is also installed in the first cavity, and a sampling assembly is provided in the sampling tube.

[0007] A first oil flow pipe is installed on one side of the sampling tube, and a second oil flow pipe is installed on the other side of the sampling tube. Both the first oil flow pipe and the second oil flow pipe are connected to the sampling tube.

[0008] A pipe clearing component is installed inside the first oil flow pipe.

[0009] As a preferred embodiment of the present invention, the sampling assembly includes a first rotating shaft, which is installed inside the sampling tube, and one end of the first rotating shaft can extend to the outside of the sampling tube;

[0010] A spiral blade is fixedly connected to the outer surface of the first rotating shaft, and the spiral blade is located inside the sampling tube.

[0011] As a preferred embodiment of the present invention, the pipe unblocking component includes a first disc, which is installed inside the first oil flow pipe, and the outer surface of the first disc is provided with a plurality of arc-shaped grooves.

[0012] The first disk is equipped with unblocking blades on its upper and lower sides respectively;

[0013] A second rotating shaft is installed at the center of the first disc shaft, and the other end of the second rotating shaft is rotatably connected to the first oil flow pipe.

[0014] As a preferred embodiment of the present invention, a first annular groove is provided on the first oil flow pipe;

[0015] The first annular groove is provided with a rotating block, one side of which is rotatably connected to the first annular groove, and the other side of which is fixedly connected to the first disc.

[0016] As a preferred embodiment of this invention, a toothed ring is fixedly connected to the outer surface of the first disk, and a driving component is provided on one side of the toothed ring.

[0017] As a preferred embodiment of the present invention, the driving component includes a first gear, one side of which can mesh with the gear ring;

[0018] A third rotating shaft is mounted on the core of the first gear;

[0019] A second gear meshes with the other side of the first gear, and a fourth shaft is mounted on the central part of the second gear.

[0020] A first helical gear is fixedly connected to the side of the outer surface of the fourth shaft away from the second gear;

[0021] A second helical gear meshes with one side of the first helical gear, the second helical gear is mounted on the outer surface of the first rotating shaft, and the second helical gear is located outside the sampling tube.

[0022] As a preferred embodiment of the present invention, a motor is provided at one end of the first rotating shaft, and the output end of the motor is fixedly connected to the first rotating shaft.

[0023] As a preferred embodiment of this invention, a one-way valve is installed in the second oil flow pipeline.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] As the oil flows out from the unloading port of the blower gear set, it flows smoothly through the first oil flow pipe. During this process, the pipe clearing component rotates, and its rotation agitates the oil within the pipe, causing it to rotate synchronously. This is done to prevent impurities and particles that may be mixed in with the oil from accumulating in the pipe, thereby preventing pipe blockage.

[0026] As the oil enters the sampling tube, the built-in light source illuminates it. With the aid of the light, the physical analysis unit performs physical analysis on the oil, thereby determining the quality and usage of the oil within the gear set, and transmitting this information to the terminal.

[0027] Additionally, as the oil flows through the sampling tube, the sampling assembly begins to rotate. This action allows the sampling assembly to guide a portion of the oil into the second oil flow channel for manual sampling and testing.

[0028] The rotational movement of the pipe cleaning component is crucial for improving oil flow. Without this component, the oil's temperature and viscosity directly affect its fluidity. Excessively high temperatures can accelerate oil oxidation, reducing its quality and potentially causing sediment buildup, increasing the risk of pipe blockage. Conversely, excessively low temperatures will make the oil viscous, reducing its fluidity and similarly increasing the likelihood of blockage. The agitation action of the pipe cleaning component improves oil flow while preventing impurities or particles from accumulating in the pipes, thus ensuring unobstructed flow.

[0036] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0037] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] Please see Figures 1 to 6 This utility model provides a fan oil condition monitoring device, including a sampling tube 1. The sampling tube 1 has a first cavity, in which a physical analysis component and a light source component are installed. The sampling tube 1 also has a sampling assembly. A first oil flow pipe 11 is installed on one side of the sampling tube 1, and a second oil flow pipe 12 is installed on the other side of the sampling tube 1. Both the first oil flow pipe 11 and the second oil flow pipe 12 are interconnected with the sampling tube 1. A pipe clearing assembly is installed in the first oil flow pipe 11.

[0039] The above solution works as follows: During use, when the oil flows out from the oil discharge port of the blower gear set, it can be connected to the first oil flow pipe 11 to ensure oil inflow. Subsequently, the pipe unblocking component rotates, which effectively agitates the oil in the pipe during rotation, achieving synchronous rotation of the oil. This effectively prevents pipe blockage caused by the deposition of impurities and particles mixed in the oil.

[0040] As the oil flows into sampling tube 1, the built-in light source emits light to illuminate the oil. With the assistance of the light source, the physical analysis unit performs physical analysis on the oil to determine its quality and usage status within the gear set, and then uploads the results to the terminal.

[0041] Simultaneously, when the oil enters the sampling tube 1, the sampling assembly begins to rotate. During this process, the sampling assembly can guide a portion of the oil into the second oil flow pipe 12, facilitating manual sampling and testing.

[0042] When the drain cleaning component rotates, it has the following effects:

[0043] Without a pipe-clearing component, the temperature and viscosity of the oil significantly affect its flowability. Excessively high temperatures accelerate the oxidation process, leading to a decline in oil quality and potentially causing sediment buildup, which can ultimately clog the pipes. Conversely, excessively low temperatures cause the oil to become too viscous, greatly reducing its flowability and also increasing the risk of blockage. Installing a pipe-clearing component effectively improves this situation. The component agitates the oil within the first oil flow pipe 11, significantly enhancing its flowability. Simultaneously, the component prevents the deposition of impurities or particles in the oil, thus ensuring unobstructed pipe flow.

[0044] It should be noted that: First, the physical analysis component is a particle sensor. Second, the light source emitted by the light source is an LED light source, which can be replaced with a laser light source, or other light sources as needed. Third, the second oil flow pipe 12 can be connected to other instruments for detecting oil, or the oil flowing out of the second oil flow pipe 12 can be collected for manual re-sampling and testing.

[0045] Please see Figure 1 , Figure 4 , Figure 5 The sampling assembly includes a first rotating shaft 2, which is installed inside the sampling tube 1. One end of the first rotating shaft 2 can extend to the outside of the sampling tube 1. A spiral blade 21 is fixedly connected to the outer surface of the first rotating shaft 2, and the spiral blade 21 is located inside the sampling tube 1.

[0046] The above scheme is adopted as follows: During use, when oil sampling and testing are required in sampling tube 1, the first rotating shaft 2 rotates. As the first rotating shaft 2 rotates, its spiral blades 21 also rotate synchronously. This rotation not only ensures that the oil can be effectively delivered to the second oil flow pipe 12 for sampling and analysis, but also improves the sampling accuracy by increasing the fluidity of the oil within the pipe. Simultaneously, the rotation of the spiral blades 21 effectively agitates the oil, preventing impurities or particles from depositing in the monitoring pipe, thereby avoiding pipe blockage.

[0047] Please see Figures 4 to 6The pipe unblocking assembly includes a first disc 3, which is installed inside the first oil flow pipe 11. The outer surface of the first disc 3 is provided with a plurality of arc-shaped through grooves 31. Unblocking blades 32 are respectively installed on the upper and lower sides of the first disc 3. A second rotating shaft 33 is installed on the central part of the first disc 3, and the other end of the second rotating shaft 33 is rotatably connected to the first oil flow pipe 11.

[0048] Using the above scheme: In use, when it is necessary to promote the flow of oil in the first oil flow pipe 11, the second rotating shaft 33 will drive the first disc 3 to rotate. During the rotation, the unblocking blades 32 installed on the upper and lower sides of the first disc 3 will rotate synchronously. The unblocking blades 32 on the upper side of the first disc 3 will come into contact with the oil in the pipe when rotating, thereby effectively promoting the flow of oil and enhancing the fluidity of oil in the pipe.

[0049] Meanwhile, the unblocking blades 32 on the upper side of the first disc 3 can effectively agitate impurities or particles in the oil during the process of pushing the oil, preventing them from settling and clogging the pipe. In this way, blockage of the first oil flow pipe 11 can be avoided, ensuring smooth oil flow.

[0050] Subsequently, the oil propelled by the unblocking blades 32 on the upper side of the first disk 3 will flow into the sampling tube 1 through the multiple arc-shaped channels 31 provided on the first disk 3.

[0051] The unblocking efficiency is further improved by the unblocking blades 32 on both the upper and lower sides, and the flow of oil is guided, thus enhancing the practicality of the device.

[0052] Please see Figure 6 The first oil flow pipe 11 is provided with a first annular groove 4; the first annular groove 4 is provided with a rotating block 41, one side of the rotating block 41 is rotatably connected to the first annular groove 4, and the other side of the rotating block 41 is fixedly connected to the first disc 3.

[0053] The above scheme is adopted: When the first disk 3 is rotating, the first disk 3 will drive the rotating block 41 on one side to rotate in the first annular groove 4. When the first disk 3 is rotating, the rotating block 41 can support the first disk 3 and improve the stability of the first disk 3 during rotation.

[0054] It should be noted that: First, a second rotating block 41 can also be provided on the other side of the first disc 3, and a second annular groove can also be opened on the first oil flow pipe 11 to increase the stability of the first disc 3 when rotating. Second, since one side of the rotating block 41 is accommodated in the first annular groove 4 and the other side of the rotating block 41 is fixed on the first disc 3, it can play a sealing role for the first oil flow pipe 11.

[0055] Please see Figure 2 and Figure 6 A toothed ring 5 is fixedly connected to the outer surface of the first disk 3, and a driving component is provided on one side of the toothed ring 5.

[0056] Using the above scheme: When the first disk 3 needs to rotate, the driving component drives the gear ring 5 to rotate. When the gear ring 5 rotates, it will drive the first disk 3 to rotate synchronously.

[0057] Please see Figures 1 to 2 The driving component includes a first gear 6, one side of which can mesh with the gear ring 5; a third rotating shaft 61 is mounted on the central part of the first gear 6; a second gear 62 meshes with the other side of the first gear 6, and a fourth rotating shaft 63 is mounted on the central part of the second gear 62; a first helical gear 64 is fixedly connected to the side of the outer surface of the fourth rotating shaft 63 away from the second gear 62; a second helical gear 65 meshes with one side of the first helical gear 64, and the second helical gear 65 is mounted on the outer surface of the first rotating shaft 2, and the second helical gear 65 is located outside the sampling tube 1.

[0058] Using the above scheme: In use, when the gear ring 5 needs to rotate, the first rotating shaft 2 drives the second helical gear 65 to rotate. As the second helical gear 65 rotates, it synchronously drives the first helical gear 64 to rotate, thus causing the fourth rotating shaft 63 to rotate in tandem with the first helical gear 64. When the fourth rotating shaft 63 rotates, it drives the second gear 62 to synchronously rotate the first gear 6, and the third rotating shaft 61 then rotates in tandem with the first gear 6. The first gear 6 effectively drives the gear ring 5 to rotate, thereby improving the efficiency and stability of the mutual transmission.

[0059] Please see Figure 3 One end of the first rotating shaft 2 is provided with a motor 7, and the output end of the motor 7 is fixedly connected to the first rotating shaft 2.

[0060] Using the above scheme: When the first rotating shaft 2 needs to rotate, the output end of the motor 7 rotates, and the output end of the motor 7 will drive the first rotating shaft 2 to rotate.

[0061] Please see Figure 5 A one-way valve 8 is installed in the second oil flow pipe 12.

[0062] Using the above scheme: When oil needs to enter the second oil flow pipe 12, the one-way valve 8 opens, and the oil is transported into the second oil flow pipe 12 by the rotation of the spiral blade 21. Then, the oil can be sampled and tested.

[0063] The working principle of this utility model:

[0064] When the oil from the blower gear set flows out through the discharge port, it connects to the first oil flow pipe, ensuring smooth oil flow. Next, the pipe clearing component begins to rotate, effectively agitating the oil inside the pipe and causing it to rotate synchronously. This operation helps prevent impurities and particles in the oil from depositing inside the pipe, thus avoiding potential pipe blockage problems.

[0065] As the oil continues to flow into the sampling tube, the built-in light source assembly emits light to illuminate the oil. With the aid of this light, the physical analysis component performs physical analysis on the oil to assess its quality and condition within the gear set. This information is then uploaded to the terminal for further processing.

[0066] Furthermore, the sampling assembly begins to rotate as the oil enters the sampling tube. During rotation, the sampling assembly extracts a portion of the oil and directs it into a second oil flow pipe for manual sampling and testing. This design makes oil quality monitoring more comprehensive and accurate.
