Description

Technical Field

[0001] This utility model relates to the field of wind power equipment technology, and in particular to a digital twin wind farm condition monitoring terminal device. Background Technology

[0002] A wind power system (also known as a wind turbine generator set) is a complete set of technical equipment systems that captures wind energy and converts it into usable electrical energy. Its core function is to use the kinetic energy generated by air flow to drive the rotation of a mechanical structure, and then use an energy conversion and control module to convert mechanical energy into electrical energy, ultimately outputting stable electrical energy that is connected to the power grid or directly supplied with energy.

[0003] However, wind farms are typically located in complex outdoor environments, facing multiple challenges such as strong winds, continuous vibrations, dust, and moisture erosion. On the one hand, vibrations and wind load impacts in the wind farm can be directly transmitted to the monitoring terminal, leading to unstable equipment operation, reduced data accuracy, and affecting the accurate judgment of the status of wind farm equipment; On the other hand, the installation angle of traditional monitoring devices is fixed or inconvenient to adjust, making it difficult to adapt to the monitoring needs of different locations and directions in wind farms, thus limiting the monitoring coverage. Meanwhile, some monitoring devices have problems such as unstable installation and insufficient sealing and anti-loosening performance. In long-term complex environments, the equipment is prone to displacement, falling off or wear and aging of internal components, which shortens the service life and increases operation and maintenance costs. In view of this, we propose a digital twin wind farm condition monitoring terminal device. Utility Model Content

[0004] Technical problems to be solved In view of the shortcomings of the existing technology, the present invention solves the above-mentioned technical problems.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: A digital twin wind farm condition monitoring terminal device includes: A column, wherein a placement block is fixedly connected to the outer side wall of the column, and an mounting plate is fixedly assembled on the outer end face of the placement block. A first mounting plate is mounted on the mounting plate by fasteners. An annular rubber pad is embedded on the inner end face of the first mounting plate facing the placement block. A first spherical seat is fixedly installed in the central area of ​​the first mounting plate, and a first connecting rod is integrally connected to the first spherical seat. The first spherical seat and the second spherical seat are spherically fitted and fitted together, and the gap between them is filled with a rubber filling pad. A rubber buffer pad is fixedly provided on the outer end face of the second spherical seat away from the first spherical seat. A second connecting rod is fixedly connected to the side of the second spherical seat away from the first spherical seat. The free end of the second connecting rod is fixedly connected to a second mounting plate, and a fixing plate is fixedly connected to the second mounting plate. Parallel sliding rods and threaded rods are passed through the fixing plate. The lower end of the slide rod is fixedly connected to a terminal fixing seat; a double-lip dustproof sealing ring and a butterfly spring are sequentially sleeved on the threaded rod along the axial direction, and the threaded rod is locked and positioned with the fixing plate in multiple positions by a first nut, a second nut and a third nut.

[0006] Preferably, the annular rubber pad is sandwiched between the first mounting plate and the placement block, and its inner sidewall is in contact with the outer sidewall of the first spherical seat.

[0007] Preferably, the first connecting rod is located on the side of the first spherical seat facing the placement block, and its free end is in clearance fit with the placement block.

[0008] Preferably, the rubber filling pad completely fills the spherical gap between the first spherical seat and the second spherical seat, and its thickness is consistent with the gap width.

[0009] Preferably, the slide rod is in sliding engagement with the fixed plate, and the threaded rod is in threaded engagement with the fixed plate.

[0010] Preferably, the double-lip dustproof sealing ring abuts against the second nut on one side and against the butterfly spring on the other side, and the butterfly spring abuts against the third nut on the other side.

[0011] Preferably, the terminal fixing base has a groove structure, and the inner wall of the groove is provided with anti-slip protrusions.

[0012] Preferably, the first mounting plate and the mounting disk are connected and fixed by at least two bolt assemblies.

[0013] Beneficial effects By setting an annular rubber pad between the first mounting plate and the placement block, filling the gap between the first spherical seat and the second spherical seat with a rubber pad, and combining it with the rubber buffer pad at the outer end of the second spherical seat, a multi-layer vibration damping and buffering structure is formed. This structure can effectively absorb the vibration transmitted by the column and the impact energy brought by the wind load in the wind field environment, avoid the vibration being directly transmitted to the monitoring terminal, greatly reduce the impact of vibration on the monitoring equipment, and ensure the stability and accuracy of data acquisition. With the help of the spherical fitting structure of the first and second spherical seats, and the elastic support of the rubber filling pad, the installation angle of the monitoring terminal can be freely adjusted, easily adapting to the monitoring needs of different locations and directions in the wind farm, significantly improving the monitoring coverage and flexibility, and angle calibration can be completed without additional disassembly and reassembly. The parallel fit design of the sliding rod and the threaded rod not only provides precise height adjustment guidance for the terminal fixing seat, but also achieves flexible height adjustment and stable fixation through multi-position locking positioning of the first nut, second nut and third nut. At the same time, the double-lip dustproof sealing ring can effectively isolate dust and moisture in the wind field, and the butterfly spring can offset the risk of loosening caused by wind vibration. It takes into account both the ease of installation and the sealing and anti-loosening performance, and extends the service life of the device. The terminal mounting base adopts a groove structure and is equipped with anti-slip protrusions on the inner wall, which can form a wrap-around fixation for the monitoring terminal, increase contact friction, and effectively prevent the monitoring terminal from shifting or falling off in complex wind field environments such as strong winds and vibrations, thus ensuring the continuous and stable operation of monitoring work. The clearance fit design between the first connecting rod and the placement block avoids structural interference during angle adjustment and ensures the degree of freedom of adjustment. The first mounting plate and the mounting plate are fixed by at least two evenly distributed bolt assemblies, which can disperse stress and prevent connection damage caused by local stress concentration. The overall structural design takes into account both flexibility and stability, can adapt to the long-term complex working environment of wind farms, and improve the overall reliability and durability of the device. Through the aforementioned structural advantages, the monitoring terminal can continuously and stably collect the status data of wind farm equipment and smoothly transmit it to the digital twin system, providing accurate and reliable data support for real-time status monitoring, data analysis, and operation and maintenance decision-making of wind farms. This helps wind farms achieve intelligent and efficient operation and maintenance, and reduces operation and maintenance costs and equipment failure risks. Attached Figure Description

[0017] Example 1: Please see Figure 1 - Figure 4 As shown in the figure, this embodiment provides a digital twin wind farm condition monitoring terminal device.

[0018] include: A column 1 has a placement block 2 fixedly connected to its outer wall. A mounting plate 3 is fixedly mounted on the outer end face of the placement block 2. A first mounting plate 4 is mounted on the mounting plate 3 via fasteners. An annular rubber pad 5 is embedded in the inner end face of the first mounting plate 4 facing the placement block 2. A first spherical seat 6 is fixedly mounted in the central area of ​​the first mounting plate 4. A first connecting rod 7 is integrally connected to the first spherical seat 6. The first spherical seat 6 and a second spherical seat 10 are spherically fitted together, and a rubber filling pad 8 is filled in the gap between them. A rubber buffer pad 9 is fixedly mounted on the outer end face of the second spherical seat 10 away from the first spherical seat 6. The second spherical seat 10 is far from the first spherical seat 6. A second connecting rod 11 is fixedly connected to one side of the spherical seat 6; a second mounting plate 13 is fixedly connected to the free end of the second connecting rod 11, and a fixing plate 12 is fixedly connected to the second mounting plate 13. A parallel sliding rod 15 and a threaded rod 21 are passed through the fixing plate 12; a terminal fixing seat 16 is fixedly connected to the lower end of the sliding rod 15; a double-lip dustproof sealing ring 18 and a butterfly spring 19 are sequentially fitted on the threaded rod 21 along the axial direction, and the threaded rod 21 is locked and positioned with the fixing plate 12 in multiple positions through a first nut 14, a second nut 17, and a third nut 20. The column 1 serves as the installation support base, and the placement block 2 on its outer side is installed... Plate 3 is fixed to the first mounting plate 4. The annular rubber pad 5 embedded inside the first mounting plate 4 can buffer the wind field vibration transmitted by the column 1, preventing the vibration from being directly transmitted to subsequent components. The spherical fitting structure of the first spherical seat 6 and the second spherical seat 10, together with the rubber filling pad 8 in the gap, can flexibly adjust the monitoring angle of the device to adapt to the monitoring needs of different locations in the wind farm. At the same time, the rubber buffer pad 9 further weakens the impact vibration brought by the wind load. The first connecting rod 7 maintains a gap fit with the placement block 2 when adjusting the angle to avoid interfering with the freedom of angle adjustment. The second connecting rod 11 connects the structure after angle adjustment with the second mounting plate 13 and the fixing plate. The 12-connector slide bar 15 provides a guide for height adjustment of the terminal mounting base 16. The threaded rod 21 achieves height locking of the terminal mounting base 16 through the first nut 14, the second nut 17, and the third nut 20. The double-lip dustproof sealing ring 18 isolates dust and moisture from the wind field, while the butterfly spring 19 counteracts the risk of loosening caused by wind vibration and maintains the stability of the locked state. The grooved structure and anti-slip protrusions of the terminal mounting base 16 can firmly fix the monitoring terminal and prevent it from shifting under wind field vibration. Finally, the wind farm equipment status data collected by the monitoring terminal can be stably transmitted to the digital twin system to support the status monitoring and analysis of the wind farm.

[0019] Example 2: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0020] The annular rubber pad 5 is sandwiched between the first mounting plate 4 and the placement block 2, and its inner sidewall is in contact with the outer sidewall of the first spherical seat 6. The annular rubber pad 5 is made of highly elastic and wear-resistant rubber material, which can play a good buffering and shock absorption role between the first mounting plate 4 and the placement block 2, effectively absorb the vibration energy caused by wind load, and reduce the impact of vibration on the monitoring device.

[0021] Example 3: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] The first connecting rod 7 is located on the side of the first spherical seat 6 facing the placement block 2, and its free end is in clearance fit with the placement block 2. This design of the first connecting rod 7 ensures connection stability while also providing a certain amount of room for movement, allowing it to adapt to a certain degree of deformation and vibration. It avoids excessive stress concentration under wind load due to overly rigid connection, thus preventing damage to the first spherical seat 6 and the placement block 2. This further improves the reliability and durability of the entire monitoring terminal device, ensuring that the monitoring terminal can work continuously and stably in complex wind farm environments, and providing accurate and reliable wind farm equipment status data for the digital twin system.

[0023] Example 4: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0024] The rubber filling pad 8 completely fills the spherical gap between the first spherical seat 6 and the second spherical seat 10, with a thickness consistent with the gap width. The rubber filling pad 8 is made of a special rubber material with high elasticity and wear resistance. This material not only has good sealing performance, effectively preventing dust, moisture and other impurities from entering the spherical gap, thus protecting the internal structure from corrosion, but its high elasticity can also further absorb and disperse the vibration and impact force generated under wind load, reduce the wear on the first spherical seat 6 and the second spherical seat 10, and extend the service life of the entire monitoring terminal device.

[0025] Example 5: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] The slide rod 15 is in sliding engagement with the fixed plate 12, and the threaded rod 21 is in threaded engagement with the fixed plate 12. The slide rod 15 can slide smoothly on the fixed plate 12, providing flexible displacement support for certain components of the device, and ensuring that the relevant structures can be precisely adjusted in position according to actual needs during the monitoring process.

[0027] Example 6: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0028] The double-lip dustproof sealing ring 18 abuts against the second nut 17 on one side and the butterfly spring 19 on the other side. The butterfly spring 19 abuts against the third nut 20 on the other side. This structural design allows the double-lip dustproof sealing ring 18 to be firmly clamped between the second nut 17 and the third nut 20, while the butterfly spring 19 provides a certain elastic buffer. During the operation of the device, the double-lip dustproof sealing ring 18 can effectively prevent dust, impurities and other contaminants from entering the key parts of the device, ensuring the cleanliness of the internal environment of the device.

[0029] Example 7: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0030] Among them, the terminal fixing base 16 has a groove structure with anti-slip protrusions on the inner wall of the groove. Through this groove structure and anti-slip protrusions, the terminal fixing base 16 can more firmly fix the relevant components and prevent them from loosening or shifting due to vibration or external force during the monitoring process. This ensures the stability and reliability of the entire device structure and provides a solid foundation for the digital twin wind farm condition monitoring work.

[0031] Example 8: This embodiment provides a digital twin wind farm condition monitoring terminal device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] The first mounting plate 4 and the mounting plate 3 are connected and fixed by at least two bolt assemblies. The bolt assemblies are evenly distributed at the connection between the first mounting plate 4 and the mounting plate 3. This connection method not only ensures the firmness of the connection between the first mounting plate 4 and the mounting plate 3, but also effectively disperses stress when the device is subjected to external impact or vibration, avoiding local stress concentration that could lead to loosening or damage to the connection, and further improving the stability and durability of the entire digital twin wind farm condition monitoring terminal device.

[0033] Working principle: The column 1 serves as the installation support base. The outer placement block 2 is fixed to the first mounting plate 4 via the mounting plate 3. The annular rubber pad 5 embedded inside the first mounting plate 4 buffers the wind field vibration transmitted by the column 1, preventing the vibration from being directly transmitted to subsequent components. The spherical fitting structure of the first spherical seat 6 and the second spherical seat 10, along with the rubber filling pad 8 in the gap, allows for flexible adjustment of the device's monitoring angle to meet the monitoring needs of different locations in the wind farm. Simultaneously, the rubber buffer pad 9 further weakens the impact vibration caused by wind loads. The first connecting rod 7 maintains a clearance fit with the placement block 2 during angle adjustment to avoid interference with the degree of freedom of angle adjustment. The second connecting rod 11 adjusts the angle... The structure connects with the second mounting plate 13 and the fixing plate 12. The slide rod 15 provides a guide for the height adjustment of the terminal fixing seat 16. The threaded rod 21 achieves height locking of the terminal fixing seat 16 through the first nut 14, the second nut 17, and the third nut 20. The double-lip dustproof sealing ring 18 isolates the dust and moisture in the wind field, while the butterfly spring 19 counteracts the risk of loosening caused by wind vibration and maintains the stability of the locked state. The grooved structure and anti-slip protrusions of the terminal fixing seat 16 can firmly fix the monitoring terminal and prevent it from shifting under wind field vibration. Finally, the wind farm equipment status data collected by the monitoring terminal can be stably transmitted to the digital twin system to support the status monitoring and analysis of the wind farm.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
