Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to an anti-collision mechanism. Background Technology

[0002] In the operation and maintenance of wind turbines, the replacement of large components inside the nacelle is a crucial step. Because the wind turbine tower is truncated cone-shaped, hoisting and replacing large components inside the nacelle presents the following two drawbacks:

[0003] On the one hand, large components may interfere with and collide with the tower wall, causing damage to the replaced components and the tower itself, affecting the performance of the components and the structure of the tower; on the other hand, during the hoisting and replacement process, large components are prone to tilting, posing serious safety risks to the entire hoisting process, and easily threatening the lives of operators and the normal operation and maintenance of wind turbine equipment. Utility Model Content

[0004] This utility model provides an anti-collision mechanism to solve at least one of the above-mentioned technical defects in the prior art. It can provide guidance for the replacement of objects, avoid tilting or collision during the replacement of objects, and improve the effectiveness and flexibility of the anti-collision mechanism.

[0015] The second anti-collision wheel assembly includes a third anti-collision wheel and a fourth anti-collision wheel, wherein the third anti-collision wheel and the fourth anti-collision wheel are respectively disposed at positions near both ends of the second support member;

[0016] The first and second anti-collision wheels, as well as the third and fourth anti-collision wheels, are all symmetrically arranged with the center line of the supporting body as the axis of symmetry.

[0017] According to the anti-collision mechanism provided by this utility model, the distance between the first anti-collision wheel and the second anti-collision wheel is greater than the distance between the third anti-collision wheel and the fourth anti-collision wheel;

[0018] And / or,

[0019] The axes of the first anti-collision wheel, the second anti-collision wheel, the third anti-collision wheel, and the fourth anti-collision wheel are all set at an angle to the center line of the supporting body.

[0020] According to the anti-collision mechanism provided by this utility model, the mounting carrier includes:

[0021] The mounting body is suitable for installation on the replacement object;

[0022] The first mounting component is located at one end of the mounting body;

[0023] The second mounting component is located at the other end of the mounting body opposite to one end;

[0024] Wherein, one of the first mounting member and the first support member is provided with a first guide member, and the other of the first mounting member and the first support member is provided with a first mating member that cooperates with the first guide member to slide.

[0025] One of the second mounting member and the second support member is provided with a second guide member, and the other of the second mounting member and the second support member is provided with a second mating member that cooperates with the second guide member to slide.

[0026] According to the anti-collision mechanism provided by this utility model, the position of the first guide member or the first mating member corresponds to the position of each anti-collision wheel provided on the first support member;

[0027] And / or, the position of the second guide or the second mating member corresponds to the position of each anti-collision wheel provided on the second support member.

[0028] According to the anti-collision mechanism provided by this utility model, both the first guide member and the second guide member include an inner sleeve; both the first mating member and the second mating member include an outer sleeve nested with the inner sleeve.

[0029] According to the anti-collision mechanism provided by this utility model, the outer wall of the inner sleeve is provided with guide ribs, the width of the guide ribs is smaller than the width of the corresponding outer wall, and the guide ribs abut against the inner wall of the outer sleeve.

[0030] According to the anti-collision mechanism provided by this utility model, the driving component includes:

[0031] A supporting body is disposed on the mounting carrier, and bearing seats are provided at intervals on the supporting body;

[0032] A transmission lead screw is mounted on the bearing housing and engages in transmission with the support component.

[0033] A driving component is adapted to connect with the transmission screw to drive the transmission screw to move, thereby causing the support component to perform linear reciprocating motion along the extension direction of the bearing body.

[0034] According to the anti-collision mechanism provided by this utility model, the driving component includes any one of the following:

[0035] The driving component includes a handle, which is inserted into the transmission lead screw to drive the transmission lead screw to move;

[0036] The driving component includes a motor, which is connected to the lead screw via a transmission component to drive the lead screw to move.

[0037] The anti-collision mechanism provided by this utility model involves installing a mounting carrier onto the replacement object, and setting a drive component on the mounting carrier to enable the support component to be driven by the drive component and move towards or away from the mounting carrier. A first anti-collision wheel set and a second anti-collision wheel set are spaced apart on the support component. When the replacement object (such as a transformer) is mounted externally on the outside of the nacelle, and the first and second anti-collision wheel sets are in contact with the tower wall, the mechanism not only provides guidance for the replacement object, preventing tilting during hoisting, but also, when the replacement object collides with the tower wall, the first and second anti-collision wheel sets contact the colliding object (tower wall), dispersing the collision force onto the wheel sets. The wheel sets, through their rolling and cushioning characteristics, reduce the impact of the collision on the replacement object, thereby protecting the replacement object connected to the mounting carrier from collision damage.

[0038] Furthermore, the drive assembly, located on the mounting carrier, provides power to the anti-collision components. Driven by this assembly, the anti-collision components can move closer to or further away from the mounting carrier. This dynamic adjustment capability allows the anti-collision mechanism to flexibly respond to different working scenarios based on actual conditions. For example, during lifting operations involving object replacement, the anti-collision components can be adjusted to a position away from the mounting carrier while still effectively preventing collisions, ensuring that the first and second anti-collision wheel sets are in the optimal anti-collision position when needed. Conversely, when the lifting operation is complete, the drive assembly can adjust the anti-collision components closer to the mounting carrier to reduce unnecessary space occupation, further improving the effectiveness and flexibility of the anti-collision mechanism.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0053] To address the problems encountered during the replacement of large components inside wind turbine nacelles, some related technologies employ fixed anti-collision devices on the replacement object to prevent it from colliding with the tower wall. However, in practical applications, especially when replacing transformers (a typical example of large wind turbine components), fixed anti-collision devices are completely ineffective in meeting the anti-collision requirements under special circumstances. Therefore, this utility model embodiment provides a novel anti-collision mechanism.

[0054] Figure 1 This is one of the structural schematic diagrams of the anti-collision mechanism provided in the embodiments of this utility model. Figure 2 This is the second structural schematic diagram of the anti-collision mechanism provided in this embodiment of the utility model.

[0055] See Figure 1 and Figure 2 This utility model embodiment provides an anti-collision mechanism 100, which is used to prevent large components being replaced inside the wind turbine nacelle from colliding with the tower 300 wall when they are hung outside the nacelle, and to prevent the large components from tilting during the hoisting process. The anti-collision mechanism 100 includes a mounting carrier 10, a drive assembly 20, and an anti-collision assembly 30.

[0056] Mounting carrier 10 may have pre-drilled mounting holes through which the replacement object 200 is mounted. Mounting carrier 10 may be made of a high-strength metal frame structure, such as steel or aluminum alloy. The shape of mounting carrier 10 is customized according to the external contour of the replacement object 200 (such as a transformer). For a relatively regular cuboid component like a transformer, mounting carrier 10 may be designed as a matching rectangular frame or an "I"-shaped frame.

[0057] Taking the replacement object 200 as a transformer as an example, the mounting carrier 10 can be fixedly connected to the transformer casing by a pin. Mounting holes that match the mounting holes of the mounting carrier 10 are pre-machined on the transformer casing. The mounting carrier 10 is then installed in the appropriate position on the transformer using a pin, ensuring that the anti-collision mechanism 100 can swing relative to the transformer during the entire hoisting and operation process.

[0058] The drive assembly 20 is located on the mounting carrier 10. The drive assembly 20 can be a linear drive module, such as a lead screw and nut pair structure, a linear motor, or an electric push rod.

[0059] The anti-collision assembly 30 includes a support member 31, a first anti-collision wheel set 32, and a second anti-collision wheel set 33. The support member 31 is in a transmission cooperation with the drive assembly 20 and is adapted to move under the driving action of the drive assembly 20 to approach or move away from the mounting carrier 10. The first anti-collision wheel set 32 ​​and the second anti-collision wheel set 33 are spaced apart on the support member 31.

[0060] The support component 31 can be a tubular or plate-like structure made of high-strength alloy material, and is equipped with a transmission plate or flange that engages with the drive assembly 20. The surface of the support component 31 can be treated with anti-corrosion measures, such as galvanizing, to prevent rust and corrosion in the humid environment where the wind turbine tower 300 is located.

[0061] The first anti-collision wheel assembly 32 is installed near the top of the support component 31. The first anti-collision wheel assembly 32 includes at least two anti-collision wheels, meaning it can include two or three anti-collision wheels. The wheel bodies are made of high-strength polyurethane material, which has good wear resistance and elasticity. Each anti-collision wheel hub is equipped with a high-precision bearing to ensure flexible wheel rotation. The second anti-collision wheel assembly 33 is similar to the first anti-collision wheel assembly 32, also including at least two anti-collision wheels, meaning it can have two or three anti-collision wheels.

[0062] A rubber buffer layer can be wrapped around the outside of each of the above-mentioned anti-collision wheels. When the anti-collision wheel comes into contact with the tower 300 wall, the rubber buffer layer can further absorb the collision energy and reduce the impact on the tower 300 wall.

[0063] It is understood that the anti-collision mechanism 100 provided by this utility model installs the mounting carrier 10 onto the replacement object 200, and sets a drive component 20 on the mounting carrier 10 so that the support component 31 is in transmission cooperation with the drive component 20 and is suitable for moving under the driving action of the drive component 20 to approach or move away from the mounting carrier 10; the first anti-collision wheel group 32 and the second anti-collision wheel group 33 are spaced apart on the support component 31. When the replacement object 200 (such as a transformer) is mounted on the outside of the nacelle, and the first anti-collision wheel set 32 ​​and the second anti-collision wheel set 33 are in contact with the tower 300 wall, they can not only provide guidance for the replacement object 200 and prevent it from tilting during the hoisting process, but also, when the replacement object 200 collides with the tower 300 wall, the first anti-collision wheel set 32 ​​and the second anti-collision wheel set 33 come into contact with the colliding object (tower 300 wall), and the collision force is dispersed to the wheel set. The wheel set reduces the impact of the collision on the replacement object 200 through its own rolling and buffering characteristics, thereby protecting the replacement object 200 connected to the mounting carrier 10 from collision damage.

[0064] Furthermore, the drive assembly 20, located on the mounting carrier 10, provides power to the anti-collision assembly 30. Through the driving action of the drive assembly 20, the anti-collision assembly 30 can move closer to or further away from the mounting carrier 10. This dynamic adjustment capability allows the anti-collision mechanism 100 to flexibly respond to different working scenarios according to actual conditions. For example, when the object 200 is being hoisted, the anti-collision assembly 30 can be adjusted to a position far from the mounting carrier 10 while still effectively preventing collisions, ensuring that the first anti-collision wheel set 32 ​​and the second anti-collision wheel set 33 are in the optimal anti-collision position when needed. Conversely, when the object 200 has completed the hoisting operation, the drive assembly 20 can adjust the anti-collision assembly 30 closer to the mounting carrier 10 to reduce unnecessary space occupation and further improve the effectiveness and flexibility of the anti-collision mechanism 100.

[0065] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the support component 31 includes a support body 311, a first support member 312, and a second support member 313. The support body 311 is in transmission cooperation with the drive assembly 20. The first support member 312 is disposed at one end of the support body 311, and the second support member 313 is disposed at the other end of the support body 311 opposite to one end.

[0066] The main support 311, the first support member 312, and the second support member 313 can all be hollow rectangular or circular steel tube structures. When the main support 311, the first support member 312, and the second support member 313 are all rectangular steel tube structures, reinforcing ribs can be provided inside the main support 311. The reinforcing ribs adopt a triangular steel plate structure to enhance the bending and torsional resistance of the main support 311.

[0067] Connecting flanges are provided at both ends of the support body 311. The connecting flanges can be connected to the support body 311 by welding. Bolt holes are provided on the connecting flanges for connection with the first support member 312 and the second support member 313. High-strength bolts can be used to connect the support body 311 to the first support member 312 and the second support member 313, or the first support member 312 and the second support member 313 can be connected to both ends of the support body 311 by welding, so that the overall frame of the support component 31 forms an "I" shape.

[0068] The first anti-collision wheel assembly 32 is mounted on the first support member 312, and the second anti-collision wheel assembly 33 is mounted on the second support member 313. Each anti-collision wheel of the first anti-collision wheel assembly 32 is mounted on the first support member 312 via a mounting bracket. The mounting bracket has a U-shaped structure and is connected to the first support member 312 by welding or bolts. The axle of the anti-collision wheel is mounted between the two side walls of the mounting bracket, and the wheel body is mounted on the axle via rolling bearings.

[0069] The mounting structure of the second anti-collision wheel assembly 33 on the second support member 313 is similar to that of the first anti-collision wheel assembly 32 on the first support member 312. That is, each anti-collision wheel is mounted on the second support member 313 by a separate "U"-shaped mounting bracket.

[0070] When the drive assembly 20 pushes the support body 311 to move, the first support member 312 and the second support member 313 move together with the support body 311 relative to the mounting carrier 10. The first anti-collision wheel assembly 32 and the second anti-collision wheel assembly 33 remain stable on their respective supports, ready to play an anti-collision role when the transformer approaches the tower wall 300, ensuring that the transformer will not collide with the tower wall 300 during hoisting.

[0071] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the first anti-collision wheel group 32 includes a first anti-collision wheel 321 and a second anti-collision wheel 322, which are respectively disposed at both ends of the first support member 312; the second anti-collision wheel group 33 includes a third anti-collision wheel 331 and a fourth anti-collision wheel 332, which are respectively disposed at both ends of the second support member 313.

[0072] Among them, the first anti-collision wheel 321, the second anti-collision wheel 322, the third anti-collision wheel 331, and the fourth anti-collision wheel 332 are all symmetrically arranged with the center line of the supporting body 311 as the axis of symmetry.

[0073] Essentially, the first anti-collision wheel 321 and the second anti-collision wheel 322 work together to form the first anti-collision wheel group 32, which prevents the transformer from colliding with the tower wall 300 during the transformer hoisting process; the third anti-collision wheel 331 and the fourth anti-collision wheel 332 work together to form the second anti-collision wheel group 33, which prevents the transformer from colliding with the tower wall 300 during the transformer hoisting process.

[0074] This utility model is illustrated using an example where each anti-collision wheel assembly includes two anti-collision wheels. The two anti-collision wheels are symmetrically arranged with the center line of the supporting body 311 as the axis of symmetry. This symmetrical arrangement ensures that when the replacement object 200 (transformer) tilts or shifts, whether to the left or right, there is a corresponding anti-collision wheel that can promptly contact the tower 300 wall to provide a balanced anti-collision function.

[0075] For example, when the transformer tilts to the left, at least one of the first anti-collision wheel 321 and the third anti-collision wheel 331 will first come into contact with the tower 300 wall and bear the impact force; when the transformer tilts to the right, at least one of the second anti-collision wheel 322 and the fourth anti-collision wheel 332 will play an anti-collision role.

[0076] Figure 3 This is a top view of the anti-collision mechanism 100 provided in this embodiment of the utility model.

[0077] See Figure 3 In some embodiments of this invention, the distance between the first anti-collision wheel 321 and the second anti-collision wheel 322 is greater than the distance between the third anti-collision wheel 331 and the fourth anti-collision wheel 332. This difference in distance is designed based on the frustum shape of the tower 300. The smaller distance between the first and second anti-collision wheels 321 and 322, which are installed near the top of the support member 31, and the larger distance between the third and fourth anti-collision wheels 331 and 332, which are installed near the bottom of the support member 31, ensures that each anti-collision wheel can contact the outer wall of the tower 300.

[0078] The axes of the first anti-collision wheel 321, the second anti-collision wheel 322, the third anti-collision wheel 331, and the fourth anti-collision wheel 332 are all set at angles to the centerline of the support body 311. This deflection difference is also designed based on the frustum shape of the tower 300 to ensure that each anti-collision wheel can effectively perform its anti-collision function under any circumstances.

[0079] It should be noted that the anti-collision mechanism 100 is designed to ensure that the distance between the first anti-collision wheel 321 and the second anti-collision wheel 322 is greater than the distance between the third anti-collision wheel 331 and the fourth anti-collision wheel 332, or that the axes of the first anti-collision wheel 321 and the second anti-collision wheel 322, as well as the axes of the third anti-collision wheel 331 and the fourth anti-collision wheel 332, are all set at an angle to the center line of the supporting body 311. Alternatively, it can be ensured that the distance between the first anti-collision wheel 321 and the second anti-collision wheel 322 is greater than the distance between the third anti-collision wheel 331 and the fourth anti-collision wheel 332, and that the axes of the first anti-collision wheel 321 and the second anti-collision wheel 322, as well as the axes of the third anti-collision wheel 331 and the fourth anti-collision wheel 332, are all set at an angle to the center line of the supporting body 311.

[0080] It should be noted that, in order to further improve the structural stability of the support component 31, the support component 31 also includes a reinforcing member 317, which is connected between the first support component 312 and the second support component 313, and is fixedly connected to the first support component 312 and the second support component 313 respectively.

[0081] The structure and material of the reinforcing member 317 are the same as those of the first support member 312 and the second support member 313.

[0082] Furthermore, the reinforcing member 317 is connected to the ends of the first support member 312 and the second support member 313. In other words, the first anti-collision wheel 321 and the third anti-collision wheel 331 are also connected by the reinforcing member 317, and the second anti-collision wheel 322 and the fourth anti-collision wheel 332 are also connected by the reinforcing member 317.

[0083] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the mounting carrier 10 includes a mounting body 11, a first mounting member 12, and a second mounting member 13. The mounting body 11 is adapted to be installed on the replacement object 200. The first mounting member 12 is disposed at one end of the mounting body 11, and the second mounting member 13 is disposed at the other end of the mounting body 11 opposite to one end.

[0084] The mounting body 11 can be a tubular or plate-shaped structure made of high-strength alloy material. The shape of the mounting body 11 is customized according to the shape of the replacement object 200 (such as a transformer). The mounting body 11 is connected to the transformer (or other replacement object 200) by a pin.

[0085] Connecting flanges are provided at both ends of the mounting body 11. The connecting flanges can be connected to the mounting body 11 by welding. Bolt holes are provided on the connecting flanges for connection with the first mounting component 12 and the second mounting component 13. High-strength bolts can be used to connect the mounting body 11 to the first mounting component 12 and the second mounting component 13, or the first mounting component 12 and the second mounting component 13 can be connected to both ends of the mounting body 11 by welding, so that the overall frame of the mounting carrier 10 forms an "I" shape, corresponding to the overall shape of the support component 31.

[0086] Essentially, the structures of each mounting component and each supporting component are adapted to each other, with the mounting components serving to provide guidance and support for the supporting components.

[0087] One of the first mounting member 12 and the first support member 312 is provided with a first guide member 314, and the other of the first mounting member 12 and the first support member 312 is provided with a first mating member 14 that cooperates with the first guide member 314 for sliding. One of the second mounting member 13 and the second support member 313 is provided with a second guide member 315, and the other of the second mounting member 13 and the second support member 313 is provided with a second mating member 15 that cooperates with the second guide member 315 for sliding.

[0088] For example, a first guide member 314 is provided on the first support member 312 at a position corresponding to the first mounting member 12. The first guide member 314 may include an inner sleeve, a guide rail, a guide slider, or a guide rod, etc. Correspondingly, a first mating member 14 is provided on the first mounting member 12 to slide in cooperation with the first guide member 314. The first mating member 14 includes an outer sleeve that mates with the inner sleeve and a guide slider that mates with the guide rail, etc.

[0089] Alternatively, a first mating member 14 can be provided on the first support member 312, and a first guide member 314 can be provided on the first mounting member 12 accordingly. The specific arrangement is the same, as long as it can provide guidance for the movement of the support member.

[0090] The structure and installation position of the second guide member 315 and the second mating member 15 are similar to those of the first guide member 314 and the first mating member 14 described above.

[0091] When each guide component includes a guide slider, the guide slider can be a dovetail-shaped slider, and the mating component is a corresponding dovetail groove. Through the cooperation of the dovetail groove and the dovetail-shaped slider, the accuracy and stability of the first anti-collision wheel assembly 32 and the second anti-collision wheel assembly 33 during the movement can be guaranteed.

[0092] When the drive assembly 20 drives the support body 311 to move, the support body 311 drives the first support member 312 and the second support member 313 to move. The first guide member 314 on the first support member 312 slides in the first mating member 14 of the first mounting member 12; the second guide member 315 on the second support member 313 slides in the second mating member 15 of the second mounting member 13, ensuring the accuracy of the movement of each anti-collision wheel.

[0093] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the position of the first guide member 314 or the first mating member 14 corresponds to the position of each anti-collision wheel provided on the first support member 312. Simultaneously, the position of the second guide member 315 or the second mating member 15 corresponds to the position of each anti-collision wheel provided on the second support member 313.

[0094] Alternatively, the position of the first guide member 314 or the first mating member 14 may correspond to the position of each anti-collision wheel provided on the first support member 312, and the second guide member 315 or the second mating member 15 may be located in the middle position of the second support member 313. Or, the first guide member 314 or the first mating member 14 may be located in the middle position of the first support member 312, and the position of the second guide member 315 or the second mating member 15 may correspond to the position of each anti-collision wheel provided on the second support member 313.

[0095] When the first support member 312 engages with the first guide member 314 via the first mating member 14, the center line of the mounting bracket of the first anti-collision wheel 321 or the second anti-collision wheel 322 is aligned with the axis of the first guide member 314, ensuring that during operation, the first anti-collision wheel 321 or the second anti-collision wheel 322 will move along the guiding direction of the first guide member 314, thereby better adapting to changes in distance from the tower wall 300 and ensuring the effectiveness of the anti-collision function.

[0096] When the second support member 313 engages with the second guide member 315 via the second mating member 15, the center line of the mounting bracket of the third anti-collision wheel 331 or the fourth anti-collision wheel 332 is aligned with the axis of the second guide member 315, ensuring that during operation, the third anti-collision wheel 331 or the fourth anti-collision wheel 332 will move along the guiding direction of the second guide member 315, thereby better adapting to changes in distance from the tower wall 300 and ensuring the effectiveness of the anti-collision function.

[0097] This configuration helps the anti-collision mechanism 100 to control the movement of the support component 31 according to the position requirements of each anti-collision wheel during operation, so that the anti-collision mechanism 100 maintains reasonable contact between the anti-collision wheel and the tower 300 wall under different working conditions, ensuring the effectiveness of the anti-collision function.

[0098] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the first guide member 314 and the second guide member 315 both include an inner sleeve; the first mating member 14 and the second mating member 15 both include an outer sleeve nested with the inner sleeve.

[0099] This configuration provides a stable guiding path for the relative movement between the support and the mounting components, ensuring that they always move relative to each other in a predetermined direction during the movement. This effectively prevents the support from shifting or wobbling relative to the mounting components, thereby improving the accuracy of the entire mechanism's movement.

[0100] Meanwhile, the nesting relationship between the inner and outer sleeves effectively disperses lateral forces. Since the outer sleeve encloses the inner sleeve, the lateral forces are absorbed by the wall of the outer sleeve and transformed into a relatively uniform stress distribution through friction between the sleeves and the overall structural integrity. This helps protect the entire guide structure and prevents component damage or deviation from the movement trajectory due to excessive lateral forces. During the operation of the anti-collision mechanism 100, even when subjected to external forces such as vibration and impact, this structural design ensures that the relative positional relationship between components remains unchanged, thereby improving the overall stability of the anti-collision mechanism 100.

[0101] In addition, if the inner sleeve or the outer sleeve is damaged during use, since the two are nested structures, they are relatively independent and easy to disassemble. The outer sleeve can be easily removed from the inner sleeve for individual component replacement without the need for large-scale disassembly of the entire anti-collision mechanism 100, thus improving the maintainability and availability of the anti-collision mechanism 100.

[0102] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the outer wall of the inner sleeve is provided with guide ribs 316, the width of the guide ribs 316 is smaller than the width of the corresponding outer wall, and the guide ribs 316 abut against the inner wall of the outer sleeve.

[0103] According to the formula for calculating friction, F=μN (where F is the frictional force, μ is the coefficient of friction, and N is the normal force), under the same normal force, reducing the contact area will reduce the frictional force. This design helps to reduce frictional losses between the inner and outer sleeves during relative motion, reduce energy loss, improve the operating efficiency of the anti-collision mechanism 100, and also extend the service life of the inner and outer sleeves.

[0104] Meanwhile, during equipment operation, if there are no guide ribs 316 between the inner and outer sleeves, jamming may occur due to the entry of dust or impurities, or slight deformation of components. The presence of guide ribs 316 can effectively prevent this from happening, thereby improving the reliability of the entire anti-collision mechanism 100 and ensuring that the anti-collision mechanism 100 can operate continuously and stably.

[0105] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the drive assembly 20 includes a bearing body 21, a transmission screw 23, and a drive member 24. The bearing body 21 is disposed on the mounting carrier 10, and bearing seats 22 are spaced apart on the bearing body 21. The transmission screw 23 is disposed on the bearing seat 22 and is in transmission cooperation with the support member 31. The drive member 24 is adapted to be connected to the transmission screw 23 to drive the transmission screw 23 to move, thereby driving the support member 31 to perform linear reciprocating motion along the bearing body 21, so as to convert the rotational motion of the transmission screw 23 into the linear reciprocating motion of the support member 31.

[0106] Figure 4 This is a schematic diagram of the usage state of the anti-collision mechanism 100 provided in this embodiment of the utility model.

[0107] The drive component 24 includes a handle, which is inserted into the transmission screw 23 to drive the transmission screw 23 to move.

[0108] See Figure 4 When the replacement device for the object 200 (such as a transformer) lifts the transformer and moves it longitudinally outward until the transformer's support legs detach from the nacelle cover, the operator stands inside the wind turbine nacelle cover and inserts a handle into the transmission screw 23. By rotating the handle, the transmission screw 23 causes the support component 31 to reciprocate linearly along the load-bearing body 21, thereby extending the inner sleeve out of the outer sleeve until the outer edges of each anti-collision wheel are flush with the end faces of the transformer's support legs. Finally, the transformer is lowered using the transformer replacement device, ensuring reliable contact between the anti-collision wheels and the outer wall of the tower 300 during the lifting process to prevent collisions and tilting accidents.

[0109] The driving component 24 may also include a motor, which is connected to the transmission screw 23 via a transmission component (belt or gear) to drive the transmission screw 23 to move.

[0110] When it is necessary to lift and replace object 200 (such as a transformer), the wind turbine control system sends a signal to the drive assembly 20 based on the position of the transformer and the distance between it and the tower wall 300. The drive assembly 20 then drives the support component 31 to move relative to the mounting carrier 10, causing the first anti-collision wheel assembly 32 and the second anti-collision wheel assembly 33 to move closer to or further away from the mounting carrier 10. This adjusts the distance between the anti-collision wheel assembly and the tower wall 300, ensuring that the transformer will not collide with the tower wall 300 during the entire lifting process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
