Description

Technical Field

[0001] This utility model relates to the technical field of power generation towers, specifically to a wind turbine tower with a transformer. Background Technology

[0002] As the global energy structure continues to evolve towards cleaner and lower-carbon directions, wind power, with its abundant resources and environmental friendliness, has become one of the fastest-growing and most strategically important technological routes in the field of renewable energy, playing a key role in achieving the goal of "carbon neutrality".

[0003] To further improve the overall efficiency of wind power generation systems and reduce construction and operation costs throughout their lifecycle, wind turbine technology is constantly being optimized and upgraded. In recent years, an integrated design that incorporates the transformer system within the wind turbine tower has gained increasing attention. This technical solution significantly shortens the power connection distance between the generator and transformer by moving the transformer body, originally located outside the tower or in a separate distribution room, into the tower. This effectively reduces line losses during high-current transmission, and decreases the amount of high-voltage cables used and related laying costs. Simultaneously, this integrated layout simplifies the electrical system structure, saves space for external infrastructure, and contributes to improving the overall integration and operational economy of the wind farm.

[0004] However, existing integrated transformer solutions within the tower still face many key technical bottlenecks, particularly in terms of ease of operation and maintenance and equipment replaceability. When transformers experience typical problems such as insulation aging, winding faults, or cooling system failures during long-term operation, on-site repairs or disassembly and replacement of critical components are often required. During such maintenance, due to the extremely narrow space inside the wind turbine tower and limited access, operators typically need to completely disassemble the coil assemblies mounted on the iron core and remove them from the tower for repair or replacement.

[0005] Currently, such operations typically require multiple maintenance personnel to work together, taking turns moving and relaying loads between steep tower ladders or narrow platforms. This is not only extremely labor-intensive and slow-paced, but also poses serious safety hazards, such as personnel falling due to exhaustion, heavy objects slipping and impacting tower walls or cable trays, and coil insulation being damaged by friction.

[0006] Therefore, the existing technology still needs further development. Utility Model Content

[0007] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a wind turbine tower with a transformer, so as to solve the technical problem in the prior art that when maintaining a transformer integrated inside a wind power generation tower, it is necessary to manually move the coil assembly outside the tower.

[0008] To achieve the above-mentioned technical objectives, according to one aspect of the present invention: a wind turbine tower with a transformer is provided, comprising: a tower body, a first platform, a transformer body, and a hoisting component. The tower body has a first chamber and a first inlet / outlet communicating with the first chamber. The first platform is disposed at the bottom of the first chamber.

[0009] Furthermore, the hoisting components include: a moving assembly, which is movably mounted on the top wall of the first chamber along a preset trajectory; and a lifting assembly, which is mounted on the moving assembly, with its hanging end for connection to the coil module, so as to lift or lower the coil module via the lifting assembly.

[0010] Furthermore, the wind turbine tower also includes a track, which is installed on the top wall of the first chamber and extends along a preset trajectory. The moving component is movably mounted on the track along the preset trajectory.

[0012] Furthermore, the wind turbine tower also includes a vibration isolator, which is disposed between the bottom of the first platform and the first chamber, and is used to provide elastic support to achieve vibration isolation.

[0013] Furthermore, the first platform includes: a first support plate and at least a pair of support rods, the first support plate being disposed above the vibration isolator; the pair of support rods being disposed on the outer wall of the first support plate respectively, and the pair of support rods being symmetrically arranged; the end of each support rod away from the first support plate being movably inserted into a movable groove on the side wall of the corresponding first chamber along the height direction of the tower body; the wind turbine tower also includes: at least two damping components, each damping component being disposed in a corresponding manner to each support rod, each damping component being disposed in a corresponding movable groove, one end of each damping component being connected to the corresponding support rod, and the other end of the damping component being connected to the bottom wall of the movable groove.

[0014] Furthermore, the wind turbine tower also includes: a housing, which is fitted onto the transformer body and is detachably connected to the first platform; the housing and the first platform form a placement space; an exhaust duct, which is located on the top of the housing and is connected to the placement space; and an exhaust fan, which is located on the outer wall of the tower body, with the end of the exhaust duct away from the housing connected to the exhaust fan, so as to exhaust the hot air in the placement space out of the tower through the exhaust fan.

[0015] Furthermore, the tower body also includes a second chamber located above the first chamber; the wind turbine tower also includes a converter, which is disposed in the second chamber and is connected to the transformer body via a connecting copper busbar.

[0016] Beneficial effects: Applying the technical solution of this utility model, a wind turbine tower with a transformer provided by this utility model includes: a tower body, a first platform, a transformer body, and a hoisting component. The tower body extends along the height direction and has a first chamber and a first entrance / exit communicating with the first chamber; the first entrance / exit facilitates the entry and exit of personnel and the movement of components. The first platform is placed inside the first chamber and is located at the bottom of the first chamber; the transformer body is placed on the first platform, which is used to support and carry the transformer body.

The hoisting component is used to lift the coil module of the transformer body and move it to the first entrance / exit, or to lift the coil module from the first entrance / exit to the location of the transformer body and accurately sleeve the coil module on the corresponding iron core.

[0017] As can be seen, in traditional technologies, transformer coil modules are typically large and heavy, requiring manual handling during maintenance. This is not only difficult to operate but also highly prone to causing personnel injury or equipment damage, resulting in high safety risks and low work efficiency. This invention addresses this by installing a movable lifting component within the first chamber of the tower body, positioned above the transformer body. This component automatically lifts and moves the coil module, directly hoisting it from the transformer location and transferring it to the first inlet / outlet. Therefore, the coil module can be safely, smoothly, and efficiently disassembled and assembled without relying on manual handling or external heavy lifting equipment, significantly shortening maintenance time, greatly reducing workload, and improving the level of mechanization and safety. Furthermore, because the lifting component is movable, the coil module can be flexibly moved inside the tower, allowing it to be precisely transported to the first inlet / outlet along a predetermined path. This effectively avoids difficult manual dragging and turning operations in confined spaces, optimizing the maintenance workflow inside the tower. Furthermore, this lifting component can not only be used to disassemble and remove the coil module, but also assist in its reassembly after maintenance. It enables precise positioning and lifting of the coil module, facilitating its easy placement onto the corresponding iron core. This allows for on-site assembly and repositioning of the transformer body inside the tower, significantly improving the flexibility and convenience of equipment installation and maintenance. Simultaneously, this invention integrates the transformer body into the first chamber inside the tower body, fully utilizing the tower's internal space. It eliminates the need for a separate transformer room outside the tower, saving floor space and structural costs, making it particularly suitable for space-constrained and complex maintenance scenarios such as offshore wind power. This invention, a wind turbine tower with a transformer, effectively solves the technical problem in existing technologies where maintenance of transformers integrated inside wind turbine towers requires manual removal of the coil assembly from the tower.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] Please see Figures 1 to 2 According to an embodiment of the present invention, a wind turbine tower with a transformer is provided, comprising: a tower body 1, a first platform 2, a transformer body 3, and a hoisting component 4. The tower body 1 has a first chamber 10 and a first inlet / outlet communicating with the first chamber 10. The first platform 2 is disposed at the bottom of the first chamber 10. The transformer body 3 is disposed on the first platform 2. The transformer body 3 has at least one coil module. The hoisting component 4 is movably disposed within the first chamber 10 and is located above the transformer body 3. The hoisting component 4 is used to lift and move the coil module of the transformer body 3 to the first inlet / outlet.

[0022] As can be seen, the wind turbine tower with transformer provided by this utility model includes: a tower body 1, a first platform 2, a transformer body 3, and a hoisting component 4. The tower body 1 extends along the height direction and has a first chamber 10 and a first entrance / exit communicating with the first chamber 10; the first entrance / exit facilitates the entry and exit of personnel and the movement of components. The first platform 2 is placed inside the first chamber 10 and is located at the bottom of the first chamber 10; the transformer body 3 is placed on the first platform 2, which is used to support and carry the transformer body 3. The transformer body 3 has at least one coil module, which is sleeved on a corresponding iron core. The hoisting component 4 is movably disposed inside the first chamber 10 and is located above the transformer body 3. The hoisting component 4 is used to lift the coil module of the transformer body 3 and move it to the first entrance / exit, or to hoist the coil module from the first entrance / exit to the location of the transformer body 3 and accurately sleeve the coil module on the corresponding iron core.

[0023] As can be seen, in traditional technologies, transformer coil modules are typically large and heavy, requiring manual handling during maintenance. This is not only difficult to operate but also highly prone to causing personnel injury or equipment damage, resulting in high safety risks and low work efficiency. This invention addresses this by installing a movable lifting component 4 within the first chamber 10 of the tower body 1, positioned above the transformer body 3. The lifting component 4 automatically lifts and moves the coil module, directly hoisting it from the transformer location and transferring it to the first inlet / outlet. This eliminates the need for manual handling or external heavy lifting equipment, enabling safe, stable, and efficient assembly and disassembly of the coil module. This significantly shortens maintenance time, greatly reduces workload, and improves mechanization and safety. Furthermore, because the lifting component 4 is movable, the coil module can be flexibly moved inside the tower, allowing it to be precisely transported along a predetermined path to the first inlet / outlet. This effectively avoids difficult manual dragging and turning operations in confined spaces, optimizing the maintenance workflow inside the tower. Furthermore, the lifting component 4 can not only be used to disassemble and remove the coil module, but also assist in its reassembly after maintenance, achieving precise positioning and lifting of the coil module. This facilitates its smooth placement onto the corresponding iron core, thereby supporting the on-site assembly and repositioning of the transformer body 3 inside the tower, significantly improving the flexibility and convenience of equipment installation and maintenance. Simultaneously, this invention integrates the transformer body 3 into the first chamber 10 inside the tower body 1, fully utilizing the tower's internal space. It eliminates the need for a separate transformer room outside the tower, saving floor space and structural costs, making it particularly suitable for space-constrained and complex maintenance scenarios such as offshore wind power. This invention, a wind turbine tower with a transformer, effectively solves the technical problem in the prior art where maintenance of transformers integrated inside wind power towers requires manual removal of the coil assembly from the tower.

[0024] Furthermore, the tower body 1 has a blocking door adapted to the first entrance / exit, which is used to block and avoid the first entrance / exit.

[0025] Optionally, the transformer body 3 has three iron cores, each corresponding to a coil module, with each coil module mounted on a corresponding iron core. After the coil module is installed, its top is equipped with fixing and connecting components such as an upper clamp and an upper yoke. When the coil module needs to be moved out of the tower body 1 for maintenance or replacement, the workers must first remove the upper clamp, upper yoke, and other auxiliary components from the top of the coil module. Subsequently, these removed components can be transferred manually or using the hoisting component 4 to the first platform 2 for temporary storage, or directly moved out of the tower through the first entrance / exit. After the auxiliary components are removed, the target coil module is lifted by the hoisting component 4 and moved to the first entrance / exit. Then, the coil module is smoothly moved out of the tower body using the conveying assembly.

[0026] When maintenance is completed and the transformer body 3 is assembled, the target coil module is first moved from outside the tower into the first chamber 10 through the first inlet / outlet. Then, the hoisting component 4 is connected to the target coil module and lifted smoothly. Driven by the hoisting component 4, the target coil module is moved directly above the transformer installation position and precisely aligned with the corresponding iron core. Afterwards, the hoisting component 4 is slowly lowered to fit the target coil module into place along the iron core axis. Once each coil module is fully in place, the upper clamps, upper yoke, and other top fixing and connecting components are installed sequentially, thus completing the overall assembly.

[0027] Furthermore, each coil module is equipped with a lifting ring, which facilitates a reliable connection with the hanging end of the lifting component 4, thereby enabling stable lifting and safe transport of the coil module.

[0028] Optionally, the transformer body 3 is a dry-type transformer.

[0029] Optionally, the conveying assembly and the first inlet / outlet are detachably connected. When it is necessary to remove heavy components such as coil modules, one end of the conveying assembly can be overlapped and fixed at the first inlet / outlet to form a continuous conveying channel, thereby facilitating the smooth removal of heavy components such as coil modules from the first chamber through the first inlet / outlet from the tower body. Specifically, the conveying assembly includes a first support and a second support extending along a preset direction. Multiple conveying rollers are provided between the first and second supports, with both ends of each conveying roller rotatably connected to the first and second supports respectively, and the conveying rollers are spaced apart along the preset direction. This allows for free rotation when the load-bearing component moves, reducing resistance through rolling friction and achieving labor-saving and smooth conveying of heavy components. Thus, through the coordinated operation of the conveying assembly and the hoisting component 4, the disassembly, transfer, and external relocation of coil modules can be completed efficiently, improving the convenience and efficiency of equipment maintenance inside the tower.

[0030] Specifically, such as Figure 2As shown, the hoisting component 4 includes: a moving component 41, which is movably mounted on the top wall of the first chamber 10 along a preset trajectory; and a lifting component 42, which is mounted on the moving component 41. The hanging end of the lifting component 42 is used to connect with the coil module so as to lift or lower the coil module.

[0031] With the above-described structure, the moving component 41 is movably mounted on the top wall of the first chamber 10 along a preset trajectory, enabling the lifting component 42 to move along the preset trajectory. The lifting component 42 is used to achieve the vertical lifting and lowering of the coil module. Through the coordinated operation of the moving component 41 and the lifting component 42, the coil module is dynamically controlled in both the movement along the preset trajectory and the vertical lifting direction. This allows for precise transfer of the coil module from its installation position to the first inlet / outlet, or precise reinstallation from the first inlet / outlet back to its installation position within the limited space of the tower, significantly improving the flexibility, ease of operation, and positioning accuracy of the hoisting operation.

[0032] Optionally, the lifting assembly 42 is an electric hoist.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the wind turbine tower also includes a track 5, which is installed on the top wall of the first chamber 10 and extends along a preset trajectory. The moving component 41 is movably mounted on the track 5 along the preset trajectory. This structural arrangement, by setting the track 5 and installing it on the top wall of the first chamber 10, extending along the preset trajectory, provides a stable and reliable guiding and supporting structure for the moving component 41. The moving component 41 can move smoothly in the horizontal direction along the track 5, ensuring that it can accurately transport the lifting component 42 and the hoisted coil module to the target position.

[0034] Furthermore, such as Figure 2 As shown, guide grooves 51 extending along the extension direction of track 5 are respectively provided on opposite sides of track 5, and the two guide grooves 51 are symmetrically arranged; the moving component 41 includes: a moving block 411, a rectangular groove 4110 is opened at the top of the moving block 411, the rectangular groove 4110 extends along the length direction of the moving block 411; a lifting component 42 is disposed at the bottom of the moving block 411; at least one pair of moving wheels 412, the pair of moving wheels 412 are rotatably disposed on opposite side walls of the rectangular groove 4110, and the pair of moving wheels 412 are respectively disposed in two guide grooves 51, and the pair of moving wheels 412 roll with the corresponding guide grooves 51 so that the moving block 411 moves along the extension direction of track 5; a driving member 413, the driving member 413 is disposed on the moving block 411, and the driving member 413 is drivenly connected to one of the moving wheels 412 of the pair of moving wheels 412 so as to drive the moving wheel 412 to rotate through the driving member 413.

[0035] With the above-described structure, the design of the guide groove 51 ensures that the moving block 411 and the lifting assembly 42 mounted on it can move precisely along the preset trajectory. The rolling engagement between the guide groove 51 and the moving wheel 412 reduces friction and ensures stability during movement, preventing deviation or swaying and improving the overall positioning accuracy of the hoisting operation. Meanwhile, the moving wheels 412 are respectively positioned within two symmetrical guide grooves 51, forming a stable support system and increasing the structural rigidity and load-bearing capacity of the entire moving assembly 41. Even during the hoisting of heavy components such as coil modules, structural deformation or instability can be effectively prevented, ensuring the safety and reliability of the equipment. Furthermore, the drive component 413 directly drives one of the moving wheels 412 to rotate, causing the entire moving block 411 and its load to move smoothly along the track 5. This electric drive method not only reduces manual labor intensity but also improves the degree of automation, making hoisting operations more flexible and efficient, especially suitable for situations where the internal space of the tower is limited and manual operation is inconvenient.

[0036] Among them, such as Figure 2 The direction indicated by the middle arrow A is the width direction of the moving block 411, and the horizontal direction perpendicular to its width direction is defined as the length direction of the moving block 411.

[0037] Optionally, the drive element 413 is a motor.

[0038] Furthermore, the movable wheel 412 is sleeved on the corresponding rotating shaft, and each rotating shaft is rotatably mounted on the movable block 411 so that the corresponding movable wheel 412 can be rotated by the rotation of each rotating shaft. The driving member 413 is drivenly connected to one of the rotating shafts so that the rotating shaft can be rotated by the driving member 413, thereby causing the movable wheel 412 to roll in the guide groove 51 of the track 5, thereby driving the entire movable assembly 41 to move along a preset trajectory.

[0039] Specifically, such as Figure 1 As shown, the wind turbine tower also includes a vibration isolator 6, which is disposed between the bottom of the first platform 2 and the first chamber 10. The vibration isolator 6 provides elastic support to achieve vibration isolation. With this structural arrangement, the transformer will generate periodic mechanical vibrations due to electromagnetic forces and load changes during operation. As an elastic support element, the vibration isolator 6 can absorb and attenuate the vibration energy transmitted from the transformer to the tower structure, significantly reducing the transmission of vibration to the tower body, avoiding tower resonance or structural fatigue, and improving the stability and reliability of the overall turbine operation.

[0040] Furthermore, there are multiple vibration isolators 6, which are spaced apart between the bottom of the first platform 2 and the first chamber 10.

[0041] Furthermore, the vibration isolator 6 not only provides elastic support for vibration isolation but also allows the first platform 2 to displace within a certain range. This design enables the first platform 2 to absorb and buffer the forces when subjected to dynamic loads or vibrations through the elastic deformation of the vibration isolator 6, thereby effectively reducing the vibration transmitted to the tower structure.

[0042] Specifically, such as Figure 1 As shown, the first platform 2 includes: a first support plate 21 and at least a pair of support rods 22. The first support plate 21 is disposed above the vibration isolator 6. The pair of support rods 22 are respectively disposed on the outer wall of the first support plate 21, and the pair of support rods 22 are symmetrically arranged. The end of each support rod 22 away from the first support plate 21 is movably inserted into the moving groove on the side wall of the corresponding first chamber 10 along the height direction of the tower body 1. The wind turbine tower also includes: at least two shock absorbers 14. Each shock absorber 14 is disposed in a one-to-one correspondence with each support rod 22. Each shock absorber 14 is disposed in the corresponding moving groove. One end of each shock absorber 14 is connected to the corresponding support rod 22, and the other end of the shock absorber 14 is connected to the bottom wall of the moving groove.

[0043] With the above-described structural design, the damping element 14, when the first platform 2 vibrates vertically, undergoes compression and rebound, participating in the absorption and dissipation of vibration energy. Working in parallel with the vibration isolator 6, it effectively increases the number of equivalent elastic elements in the system, significantly improving the isolation efficiency against power frequency vibrations generated during transformer operation. Furthermore, the damping element 14 provides auxiliary vertical support points from the side via the support rod 22, ensuring that the load on the first platform 2 is borne jointly by the center and sides, significantly improving the structural stress distribution and preventing the vibration isolator from aging or failing due to uneven loading or localized overvoltage.

[0044] Furthermore, the movable groove on the side wall of the first chamber 10 extends along the height direction of the tower body 1.

[0045] The bottom wall of the moving trough refers to the side wall of the moving trough near the bottom of the first chamber 10.

[0046] Alternatively, the shock absorber 14 can be a spring or a rubber buffer pad.

[0047] Specifically, such as Figure 1 As shown, the wind turbine tower also includes: a housing 7, which is fitted onto the transformer body 3 and is detachably connected to the first platform 2; the housing 7 and the first platform 2 form a placement space; an exhaust duct 8, which is located on the top of the housing 7 and communicates with the placement space; and an exhaust fan 9, which is located on the outer wall of the tower body 1, with the end of the exhaust duct 8 away from the housing 7 connected to the exhaust fan 9 so that the hot air in the placement space can be discharged outside the tower through the exhaust fan 9.

[0048] With the above-described structure, the exhaust duct 8 is located at the top of the housing 7 and connects to the placement space. The exhaust fan 9 is installed on the outer wall of the tower body 1 and connected to the exhaust duct 8. When the transformer generates heat during operation, the exhaust fan 9 starts, using negative pressure suction to force the hot air inside the housing out of the tower through the exhaust duct, forming a highly efficient airflow path of "hot air rising → centralized extraction → external exhaust," achieving continuous and active ventilation and cooling, and preventing the transformer from overheating and causing insulation aging or failure. In addition, the housing 7 and the first platform 2 are detachably connected, facilitating quick disassembly of the housing 7 when maintenance or transformer replacement is required, without affecting other components.

[0049] Optionally, the enclosure 7 adopts a detachable structure design, which facilitates quick assembly and disassembly according to maintenance or repair needs. This design allows for convenient opening or removal of the enclosure when the transformer needs repair, replacement, or routine inspection, thereby effectively improving the maintainability and operational efficiency of the equipment.

[0050] Optionally, the shape of the enclosure 7 can be flexibly designed according to the actual layout of the transformer body and the internal space conditions of the tower, so as to achieve the optimization of structural adaptation and space utilization.

[0051] Optionally, the positions of the exhaust duct 8 and the exhaust fan 9 can be reasonably arranged according to the specific installation position of the transformer body 3, so as to minimize the duct path, reduce airflow resistance, improve exhaust efficiency, and achieve a high-efficiency and low-energy heat dissipation effect.

[0052] Specifically, such as Figure 1 As shown, the tower body 1 also includes a second chamber 11, which is located above the first chamber 10; the wind turbine tower also includes a converter 12, which is disposed in the second chamber 11 and is connected to the transformer body 3 via a connecting copper busbar 13.

[0053] With the above-described structural arrangement, the converter 12 is placed in the second chamber 11, and the transformer body 3 is placed in the first chamber 10, forming a vertically integrated layout of "converter above, transformer below." This fully utilizes the vertical space of the tower, avoids planar stacking of equipment, significantly improves space utilization, and is suitable for compact tower designs. Furthermore, the converter 12 and the transformer body 3 are directly connected via a connecting copper busbar 13, and since they are located in adjacent chambers, the electrical path is short and the layout is compact. The copper busbar has advantages such as high current carrying capacity, low resistance, and good heat dissipation, which can effectively reduce resistance loss and voltage drop during power transmission, improving system efficiency.
