Description

Technical Field

[0001] This application relates to the field of wind power technology, and in particular to an installation fixture and method for a collector ring. Background Technology

[0002] In recent years, with the rapid development of the wind power industry, the number of main engine manufacturers and the installed capacity of wind turbine generators have grown rapidly. As a result, competition in the wind power industry has become increasingly fierce. While focusing on the procurement cost of main engines, the efficiency of unit assembly has also become a key factor.

[0003] Some wind turbine units have adopted slip rings instead of the traditional cable twisting method when connecting power cables, which has improved the efficiency and quality of cable connection. However, because the slip rings are installed on the top platform of the top section of the tower, although the slip rings themselves are small in size and weight, they currently need to be hoisted into the top section of the tower. The main crane is used to hoist the slip rings separately in one go to complete the installation. Therefore, compared with the installation of units that do not use slip rings, the installation time of the entire unit will be increased by the installation time of the slip rings, which reduces the assembly efficiency of the wind turbine units. Summary of the Invention

[0004] This application provides a slip ring installation fixture and installation method, which can improve the unit assembly efficiency.

[0005] On one hand, according to an embodiment of this application, an installation fixture for a slip ring is proposed, comprising: a base having an installation space and a connecting end disposed away from the installation space; a rotating assembly disposed in the installation space and rotatably connected to the base; a lifting drive assembly disposed on the rotating assembly, the lifting drive assembly including a lifting component and a driving component, the lifting component including a mating part and a lifting part connected to each other, the mating part having a degree of freedom of movement relative to the rotating assembly, the driving component being supported on the rotating assembly and being drively connected to the mating part to drive the lifting part to move closer to or away from the rotating assembly; and a connecting assembly connected to the lifting part, the connecting assembly being configured to connect to the slip ring.

The first limiting part is connected to the seat unit and surrounds the groove to form a mating cavity. The rotating component part is inserted into the mating cavity and rotates in cooperation with the seat unit and the first limiting part.

[0008] According to one aspect of the embodiments of this application, the seat unit includes a first beam, a second beam, and a connecting beam.

[0009] According to one aspect of the embodiments of this application, the rotating assembly includes a main body and rotating shafts located on both sides of the main body. Each rotating shaft is inserted into a base and has a clearance fit with the base. The main body is provided with a clearance hole that extends through its own thickness direction. A lifting part is spaced apart from the main body in the thickness direction. A mating part is inserted into the clearance hole. The mating part is connected to the lifting part on one side in the thickness direction and is in contact with the driving component on the other side.

[0010] According to one aspect of the embodiments of this application, the mating part is provided with teeth, and the driving component includes a force-applying part and a force-transmitting part. The force-transmitting part is in transmission engagement with the teeth, and the force-applying part is connected to the force-transmitting part.

[0011] According to one aspect of the embodiments of this application, the mating parts are arranged in pairs and spaced apart, and a force transmission part is provided for each mating part. The force transmission part includes a multi-stage transmission wheel that meshes with each other. The transmission wheels at the input end of the paired force transmission parts mesh with each other, and the transmission wheels at the output end mesh with the corresponding mating parts. The force application part is connected to the transmission wheel at the input end of one of the force transmission parts.

[0012] According to one aspect of the embodiments of this application, the transmission wheel includes transmission teeth, and the number of teeth of the transmission wheel located at the input end is less than the number of teeth of the transmission wheel located at the output end.

[0013] According to one aspect of the embodiments of this application, the connecting assembly includes a plurality of slings, one end of each sling being connected to a lifting part, and the other end of each sling being freely disposed and used to connect to a slip ring.

[0014] According to one aspect of the embodiments of this application, the installation fixture further includes a limiting component, which is detachably connected to the lifting drive component to lock or unlock the degree of freedom of movement of the mating part relative to the rotating component.

[0015] In another aspect, an embodiment of this application provides a method for installing a slip ring, comprising:

[0016] Provide a collector ring and n tower sections, n≥3. Stack the first to the (n-1)th tower sections sequentially and place the nth tower section horizontally.

[0017] Provide the above-mentioned installation fixtures to connect the connection end of the base to the end flange of the nth tower section;

[0018] Connect the slip ring to the connection assembly;

[0019] Adjust the orientation of the nth tower segment so that the nth tower segment changes from horizontal to vertical placement. Under the action of gravity, the rotating component drives the lifting drive component, the connecting component, and the collector ring to rotate relative to the base, so that the collector ring is in a vertical state.

[0020] Hoist the nth tower section above the (n-1)th tower section and connect it to the (n-1)th tower section;

[0021] Install the collector ring onto the mounting platform of one of the tower sections and remove the installation fixtures.

[0022] According to another aspect of the embodiments of this application, the step of connecting the slip ring to the connection assembly includes:

[0023] Place the collector ring inside the nth tower section and position it opposite to the installation fixture;

[0024] The control drive component drives the mating part to move relative to the rotating assembly, thereby driving the hoisting part to move away from the rotating assembly to a first predetermined position, so that the slip ring is located within the connection range of the connecting assembly;

[0025] Connect the connecting component to the slip ring;

[0026] The control drive component drives the mating part to move relative to the rotating assembly, thereby driving the hoisting part to move towards the rotating assembly to a second predetermined position, so that when the collector ring rotates relative to the base, the components in the tower section can give way to the collector ring.

[0027] According to one aspect of the embodiments of this application, before the step of adjusting the attitude of the nth tower segment, the installation method further includes: locking the lifting drive assembly to lock the degree of freedom of movement of the mating part relative to the rotating assembly.

[0028] According to the installation fixture and method for the slip ring provided in the embodiments of this application, the installation fixture for the slip ring includes a base, a rotating component, a lifting drive component, and a connecting component. The connection to the tower section can be achieved through the connecting end of the base. The rotating component is rotatably connected to the base. The lifting drive component is disposed on the rotating component. The connecting component can be used to connect the slip ring. It is connected to the connecting component through the hoisting part. Since the driving component is connected to the mating part through transmission, it can drive the mating part to move relative to the rotating component and drive the hoisting part and the connecting component to move, thereby realizing the connection with the slip ring and the position adjustment. Furthermore, the rotating component's rotatable connection to the base allows the slip ring to be connected while the tower section is horizontal. The radial dimension is much smaller than the axial dimension, reducing the difficulty of connecting the connecting component and the slip ring. After connection, the tower section is hoisted to a vertical position. Under the action of gravity, the rotating component will drive the lifting drive component, connecting component, and slip ring to rotate relative to the base, ensuring that the bottom surface of the slip ring is always parallel to the ground. This enables synchronous hoisting and installation with the top tower section, eliminating the need for additional slip ring hoisting, saving wind turbine assembly time and improving assembly efficiency.

[0060] In recent years, with the rapid development of the wind power industry, the number of main engine manufacturers and the installed capacity of wind turbine generators have grown rapidly. As a result, competition in the wind power industry has become increasingly fierce. While focusing on the procurement cost of main engines, the efficiency of unit assembly has also become a key factor.

[0061] Some wind turbine units have adopted slip rings instead of the traditional cable twisting method for power cable connection, which has improved the efficiency and quality of cable connection. However, because the slip rings are installed on the top platform of the top section of the tower, although the slip rings themselves are small in size and weight, they currently need to be hoisted into the top section of the tower. The main crane is used to hoist the slip rings in one go to complete the installation process, which takes 1-1.5 hours. Therefore, the installation time of the wind turbine units using slip rings will increase by 1-1.5 hours, affecting the assembly efficiency of the wind turbine units and the construction cost.

[0062] Therefore, in order to solve the above-mentioned technical problems, one embodiment of this application provides a slip ring installation fixture and installation method, which can improve the unit assembly efficiency.

[0063] like Figures 1 to 7As shown in one embodiment of this application, a slip ring 200 mounting fixture 100 includes a base 10, a rotating assembly 20, a lifting drive assembly 30, and a connecting assembly 40. The base 10 has an mounting space 12 and a connecting end 13 disposed away from the mounting space 12. The rotating assembly 20 is disposed in the mounting space 12 and rotatably connected to the base 10. The lifting drive assembly 30 is disposed on the rotating assembly 20 and includes a lifting component 31 and a driving component 32. The lifting component 31 includes a mating part 311 and a lifting part 312 connected to each other. The mating part 311 has a degree of freedom of movement relative to the rotating assembly 20. The driving component 32 is supported on the rotating assembly 20 and is drively connected to the mating part 311 to drive the lifting part 312 to move closer to or away from the rotating assembly 20. The connecting assembly 40 is connected to the lifting part 312 and is configured to connect to the slip ring 200.

[0064] The base 10 may include a ring structure. Alternatively, the base 10 may consist of two or more base units spaced apart around the same axis. The mounting space 12 of the base 10 may be a closed cavity. However, in some embodiments, the mounting space 12 may also be an open cavity in the circumferential direction. The connecting end 13 of the base 10, located away from the mounting space 12, can be used to connect to the tower section 300 at the top of the tower. The connecting end 13 may be provided with connecting holes or connecting bolts.

[0065] The base 10 may have a thickness direction, and the mounting space 12 may extend through the base 10 along its thickness direction. When the mounting fixture 100 is connected to the tower section 300, the thickness direction may be the axial direction of the tower section 300. Along the thickness direction of the base 10, the orthographic projection of the connecting component 40 may be located in the orthographic projection of the mounting space 12, and one of the base 10 and the connecting component 40 may partially extend into the interior of the other and be rotatably connected to each other. The base 10 and the connecting component 40 may be directly rotatably fitted, or a bearing or a copper sleeve may be provided between them to achieve a rotatable connection.

[0066] The lifting drive assembly 30 is mounted on the rotating assembly 20 and can rotate relative to the base 10 with the rotating assembly 20. The mating part 311 can have a degree of freedom of movement relative to the rotating assembly 20 by providing clearance holes or guide channels on the rotating assembly 20. The drive component 32 may include structures such as a motor drive or a telescopic cylinder drive and is connected to the mating part 311 for transmission, so as to drive the hoisting part 312 to move closer to or away from the rotating assembly 20.

[0067] The connecting assembly 40 is connected to the lifting unit 312. The connecting assembly 40 may include deformable flexible components, such as flexible belts, flexible locks, wire ropes, chains, etc. Of course, the connecting assembly 40 may also include rigid components, such as connecting rods.

[0068] An embodiment of this application provides an installation fixture 100 that can be connected to the tower section 300 via the connecting end 13 of the base 10. The rotating component 20 is rotatably connected to the base 10. The lifting drive component 30 is mounted on the rotating component 20. The connecting component 40 can be used to connect the slip ring 200. It is connected to the connecting component 40 via the hoisting part 312. Since the driving component 32 is connected to the mating part 311, it can drive the mating part 311 to move relative to the rotating component 20 and drive the hoisting part 312 and the connecting component 40 to move, thereby realizing the connection with the slip ring 200 and position adjustment. Furthermore, the rotatable connection between the rotating component 20 and the base 10 allows the collector ring 200 to be connected in a horizontal state of the tower section 300. The radial dimension is much smaller than the axial dimension, reducing the difficulty of connecting the connecting component 40 and the collector ring 200. After connection, the tower section 300 is hoisted to a vertical state. Under the action of gravity, the rotating component 20 will drive the lifting drive component 30, the connecting component 40, and the collector ring 200 to rotate relative to the base 10, so that the bottom surface of the collector ring 200 is always parallel to the ground. This achieves synchronous hoisting and installation with the top tower section 300, eliminating the need for additional hoisting of the collector ring 200, saving wind turbine assembly time and improving assembly efficiency.

[0069] In some optional embodiments, one embodiment of the present application provides an installation fixture 100, a base 10 including paired seat units 11, an installation space 12 located between the paired seat units 11, a connecting end 13 including a plurality of connecting holes 131 disposed on the seat unit 11, and a rotating component 20 rotatably connected to each seat unit 11.

[0070] The paired seat units 11 can be symmetrically distributed. When they are used in conjunction with the tower section 300, the paired seat units 11 can be distributed along the radial direction of the tower section 300.

[0071] The paired seat units 11 can be rotatably connected to the rotating assembly 20 at their ends facing each other. The paired seat units 11 are provided with multiple connection holes 131 at their ends facing away from each other.

[0072] Please see Figures 1 to 3As shown, an embodiment of the present application provides an installation fixture 100 that, by including paired seat units 11 in the base 10, ensures the rotational connection requirements with the rotating assembly 20. Furthermore, this arrangement eliminates the need for the base 10 to be arranged in a complete circumferential direction, reducing costs and preventing interference when the rotating assembly 20 drives the lifting drive assembly 30 to rotate relative to the base 10, thus ensuring smooth rotation.

[0073] In some optional embodiments, one embodiment of the present application provides an installation fixture 100, wherein the seat unit 11 has a groove 111 and a first limiting part 14 is provided on the seat unit 11. The first limiting part 14 is connected to the seat unit 11 and surrounds the groove 111 to form a mating cavity. The rotating component 20 is partially inserted into the mating cavity and rotates in cooperation with the seat unit 11 and the first limiting part 14.

[0074] The groove 111 can be an arc-shaped groove 111.

[0075] The first limiting part 14 and the base unit 11 can be fixedly connected, for example, by welding. Alternatively, a detachable connection using fasteners such as bolts can be used to achieve the connection requirement with the base unit 11. A detachable connection method is optional.

[0076] Optionally, the first limiting part 14 may also be provided with a recess that faces away from the seat unit 11, which communicates with the groove 111 and surrounds it to form an insertion cavity. The rotating component 20 can be partially inserted into the insertion cavity and detachably connected to the seat unit 11 and the first limiting part 14.

[0077] An embodiment of this application provides an installation fixture 100, which, by providing a groove 111 on the seat unit 11, can limit the rotation component 20. Furthermore, the seat unit 11 and the first limiting part 14 are separately provided, so that the first limiting part 14 can be installed after the rotation component 20 is placed in the groove 111 of the seat unit 11, thereby reducing the assembly difficulty of the rotation component 20.

[0078] In some optional embodiments, the installation fixture 100 provided in one embodiment of this application includes a base unit 11 comprising a first beam 112, a second beam 113 and a connecting beam 114. One end of the first beam 112 and the second beam 113 converges and is rotatably connected to the rotating assembly 20. The other ends of the first beam 112 and the second beam 113 are dispersed in a direction away from each other and are respectively provided with connecting holes 131. The connecting beam 114 is connected to the first beam 112 and the second beam 113.

[0079] The end where the first beam 112 and the second beam 113 converge can be directly or indirectly rotatably connected to the rotating component 20. The first beam 112 and the second beam 113 are provided with multiple connecting holes 131 at their respective ends, and the centers of each connecting hole 131 can be located on the same pitch circle.

[0080] The installation fixture 100 provided in one embodiment of this application, through the above-mentioned settings, makes the seat unit 11 have high overall strength, is stable and reliable and not easily deformed, thus ensuring the stability of the rotating component 20 when it is flipped over.

[0081] Continue reading Figures 1 to 3 As shown, in some optional embodiments, the mounting fixture 100 provided in one embodiment of this application further includes a bending plate 115 in the base unit 11. The bending plate 115 includes a first plate 115a and a second plate 115b that are arranged intersectingly. The end of the first beam 112 and the second beam 113 that converges is connected and fixed to the first plate 115a. Optionally, it can be fixed by welding or other methods. The groove 111 can be provided on the second plate 115b.

[0082] The above configuration facilitates the convergence connection between the first beam 112 and the second beam 113, as well as the rotational connection with the transition assembly.

[0083] Please see Figures 1 to 4 As shown, in some optional embodiments, the installation fixture 100 provided in one embodiment of this application includes a rotating assembly 20 comprising a main body 21 and rotating shafts 22 located on both sides of the main body 21. Each rotating shaft 22 is inserted into a base 10 and has a clearance fit with the base 10. The main body 21 is provided with a clearance hole 211 that extends through along its own thickness direction X. A lifting part 312 is spaced apart from the main body 21 in the thickness direction X. A mating part 311 is inserted into the clearance hole 211. The mating part 311 is connected to the lifting part 312 on one side in the thickness direction X and is in contact with the driving component 32 on the other side.

[0084] The main body 21 may include a plate-like structure, and the main body 21 and the rotating shaft 22 may be connected by a fixed connection. The rotating shafts 22 on both sides of the main body 21 may be symmetrically distributed. Each rotating shaft 22 is disposed opposite to one of the seat units 11 and is rotatably connected to each other.

[0085] The shape of the clearance hole 211 can match the shape of the mating part 311 and have a clearance fit with the mating part 311.

[0086] The drive component 32 and the hoisting part 312 can be respectively provided on both sides of the main body 21 in the thickness direction X.

[0087] The drive component 32 and the hoisting part 312 can drive the mating part 311 to move by means of transmission gear contact and transmission engagement. Of course, the drive component 32 can be connected to the mating part 311 by means of telescopic cylinder, etc., and the mating part 311 can be moved by the extension and retraction of the telescopic cylinder. Both can meet the functional requirements of the drive component.

[0088] An embodiment of this application provides an installation fixture 100 in which the rotating component 20 adopts the above-described structure, which facilitates the rotational engagement with the base 10. Furthermore, the provision of the clearance hole 211 on the main body 21, as well as the engagement relationship between the mating part 311, the hoisting part 312, and the driving component 32, while ensuring the synchronous rotation of the lifting drive component 30 and the rotating component 20, facilitates the driving of the hoisting part 312, enabling it to move towards or away from the rotating component 20, thus ensuring the hoisting or release of the slip ring 200.

[0089] Please see Figures 1 to 5 As shown, in some optional embodiments, the installation fixture 100 provided in one embodiment of this application has a toothed part 311a on the mating part 311, and the driving component 32 includes a force-applying part 321 and a force-transmitting part 322. The force-transmitting part 322 is in transmission engagement with the toothed part 311a, and the force-applying part 321 is connected to the force-transmitting part 322.

[0090] The force-applying part 321 can be a drive handle or a drive motor, and the force-transmitting part 322 can include a transmission structure such as a gear or a sprocket.

[0091] The teeth 311a provided on the mating part 311 can be multiple and distributed along the thickness direction X of the main body part 21.

[0092] An embodiment of this application provides an installation fixture 100, which, through the above-described configuration, enables the force-applying part 321 to apply force to the force-transmitting part 322. Through the meshing and transmission between the force-transmitting part 322 and the toothed part 311a, the mating part 311 moves along the thickness direction X, ensuring the driving requirements.

[0093] In some optional embodiments, the installation fixture 100 provided in one embodiment of this application has mating parts 311 arranged in pairs and spaced apart. Each mating part 311 is provided with a force transmission part 322. The force transmission part 322 includes a multi-stage transmission wheel 322a that meshes with each other. The transmission wheels 322a at the input end of the paired force transmission parts 322 mesh with each other, and the transmission wheels 322a at the output end mesh with the corresponding mating part 311. The force application part 321 is connected to the transmission wheel 322a at the input end of one of the force transmission parts 322.

[0094] The multi-stage transmission wheel 322a may include two transmission wheels 322a, three transmission wheels 322a, or multiple transmission wheels 322a. Optionally, it may include two transmission wheels 322a. The transmission wheels 322a may optionally include gears, etc.

[0095] An embodiment of this application provides an installation fixture 100, which, by arranging mating parts 311 in pairs, enables each mating part 311 to be connected to a lifting part 312, thereby achieving multi-point connection of the lifting part 312, ensuring the stability of the lifting part 312 when it is driven to move closer to or away from the rotating component 20, and thus ensuring the safety of the slip ring 200 during lifting.

[0096] By engaging the transmission wheels 322a at the input end of the paired force transmission parts 322, the two force transmission parts 322 can be driven to move synchronously by the same force application part 321, thereby driving the paired mating parts 311 to move along the thickness direction X, thus driving the hoisting part 312.

[0097] In some alternative embodiments, the mounting fixture 100 provided in one embodiment of this application, according to one aspect of the embodiment of this application, includes a transmission wheel 322a including transmission teeth, wherein the number of teeth of the transmission wheel 322a located at the input end of the force transmission part 322 is less than the number of teeth of the transmission wheel 322a located at the output end.

[0098] With the above settings, the lifting speed of the mating part 311 can be reduced, and the torque required for the lifting drive assembly 30 to lift the slip ring 200 can be reduced, thereby ensuring that the lifting of the slip ring 200 in the vertical direction can be completed by personnel operation without the aid of external auxiliary equipment.

[0099] In some alternative embodiments, the installation fixture 100 provided in one embodiment of this application includes two transmission wheels 322a in each force transmission part 322. The radial dimension of the transmission wheel 322a that is in transmission with the mating part 311 is larger than the dimension of the transmission wheel 322a at the input end of the force transmission part 322. The transmission wheel 322a at the input end refers to the wheel in which the two mating parts 311 mesh with each other.

[0100] In some optional embodiments, the installation fixture 100 provided in one embodiment of this application has a protruding structure 23 on the main body 21 of the rotating component 20. The protruding structure 23 protrudes away from the side where the lifting part 312 is located in the thickness direction X. A protruding structure 23 is provided for each transmission wheel 322a. The rotating wheel is supported on the protruding structure 23 and rotates in cooperation with the protruding structure 23.

[0101] An embodiment of this application provides an installation fixture 100, which, by setting a protruding structure, facilitates the support of each transmission wheel 322a, ensures the rotation requirements of the transmission wheel 322a, and avoids interference caused by multiple transmissions in the main body 21 and other structures.

[0102] In some optional embodiments, the installation fixture 100 provided in one embodiment of this application includes a connecting component 40 comprising a plurality of slings 41, one end of each sling 41 being connected to the lifting part 312, and the other end of each sling 41 being freely disposed and used to connect to the slip ring 200.

[0103] The number of slings 41 can be three, four, or more. Each sling 41 can be connected to the lifting unit 312 by means of hooks or other methods, thus achieving multi-point connection with the slip ring 200 and ensuring the stability of the slip ring 200 during lifting and rotation. Furthermore, the structure of the slings 41 has a certain buffering effect, reducing damage to the slip ring 200 caused by rigid connections.

[0104] Please see Figures 1 to 6 As shown, in some optional embodiments, one embodiment of this application provides an installation fixture 100, which further includes a limiting component 50. The limiting component 50 is detachably connected to the lifting drive component 30 to lock or unlock the degree of freedom of movement of the mating part 311 relative to the rotating component 20.

[0105] The limiting component 50 may include a limiting shaft inserted between the mating part 311 and the rotating component 20. Of course, the limiting component 50 may also include a limiting rod detachably connected between the two force transmission parts 322.

[0106] In some optional embodiments, the limiting component 50 may include a limiting rod, which may be provided with at least two through holes or U-shaped slots. Among the transmission wheels 322a included in the two force transmission parts 322, at least one transmission wheel 322a of each can be inserted into the U-shaped slot or through hole and detachably connected to the limiting rod to realize the degree of freedom of movement of the locking or unlocking mating part 311 relative to the rotating component 20.

[0107] An embodiment of this application provides an installation fixture 100. By setting a limiting component 50, after the slip ring 200 is connected to the connecting component 40 and the height is adjusted, the limiting component 50 can lock the degree of freedom of movement of the mating part 311 relative to the rotating component 20, thereby ensuring the safety and reliability of the slip ring 200 during the hoisting process.

[0108] Please see Figures 1 to 10 As shown, on the other hand, one embodiment of this application also provides a method for installing a slip ring 200, including...

[0109] S100 provides a collector ring 200 and n tower sections 300, where n ≥ 3. The first to (n-1)th tower sections 300 are stacked sequentially, and the nth tower section 300 is placed horizontally. (See details in [link to documentation]). Figure 8 The structure shown is as follows.

[0110] S200, Provide an installation fixture 100 according to any of the above embodiments to connect the connection end 13 of the base 10 to the end flange of the nth tower section 300.

[0111] S300, Connect the slip ring 200 to the connecting assembly 40.

[0112] S400. Adjust the orientation of the nth tower segment 300, changing it from a horizontal to a vertical position. See details in [link to documentation]. Figure 8 attitude to Figure 9 The attitude is adjusted so that the rotating component 20 drives the lifting drive component 30, the connecting component 40 and the collector ring 200 to rotate relative to the base 10 under the action of gravity, so that the collector ring 200 is in a vertical state.

[0113] S500, hoist the nth tower section 300 above the (n-1)th tower section 300 and connect it to the (n-1)th tower section 300.

[0114] S600, Install the slip ring 200 onto the mounting platform of one of the tower sections 300 and remove the installation fixture 100.

[0115] In step S100, n can be 3, 4, 5, or a larger value. During tower construction, the bottommost tower section 300 is the first tower section 300, and the topmost tower section 300 is the nth tower section 300. The first to (n-1)th tower sections 300 are stacked sequentially along the axial direction, and adjacent tower sections 300 can be connected as a whole using bolts or other fasteners.

[0116] Before the nth tower section 300 is hoisted above the (n-1)th tower section 300, the nth tower section 300 is placed horizontally on the ground or the corresponding support platform. Horizontal placement can be understood as the axis of the tower section 300 being parallel to the horizontal plane, or parallel to the bottom surface / support platform or other surfaces used to support the tower section 300.

[0117] In step S200, the connecting end 13 of the base 10 can be connected to the end flange of the tower section 300 by fasteners such as bolts. The connection can be achieved directly using the flange holes on the end flange without the need for additional drilling to damage the structure of the tower section 300.

[0118] In step S300, the slip ring 200 and the connecting component 40 can be connected by binding, hooking or other methods, or the slip ring 200 can be connected to the connecting component 40 by the lifting lug structure on its own.

[0119] In step S400, the nth tower section 300 can be flipped over by hoisting the tower section 300 to switch from horizontal to vertical placement. Optionally, two cranes can be used to flip the nth tower section 300. During the flipping process, the collector ring 200 also rotates under the action of the rotating component 20, which can ensure that the lower plane of the collector ring 200 remains parallel to the ground. When the top nth tower section 300 completes the flipping and reaches the vertical state, the collector ring 200 stops rotating, and the collector ring 200 has also reached the vertical state.

[0120] In step S500, a crane can be used to lift the nth tower section 300 above the (n-1)th tower section 300 and connect it to the (n-1)th tower section 300.

[0121] In step S600, the collector ring 200 is installed onto the mounting platform of one of the tower sections 300 and the mounting fixture 100 is removed.

[0122] Optionally, a force can be applied to the force-applying part 321 to prevent it from rotating. Remove the limiting device. Rotate the force-applying part 321 to drive the transmission wheel 322a to rotate, thereby driving the mating part 311 to move along the thickness direction X and causing the slip ring 200 to fall to the installation position on the tower platform. Complete the installation and fixing of the slip ring 200, and remove the slip ring 200 installation fixture 100.

[0123] The method for installing the slip ring 200 provided in one embodiment of this application can achieve synchronous hoisting and installation with the top tower section 300, without the need for additional hoisting of the slip ring 200, thus saving the assembly time of the wind turbine generator set and improving the assembly efficiency.

[0124] In some optional embodiments, one embodiment of the present application provides an installation method for connecting the slip ring 200 to the connection assembly 40, which includes the following steps:

[0125] Place the collector ring 200 inside the nth tower section 300 and position it opposite to the installation fixture 100.

[0126] The control drive component 32 drives the mating part 311 to move relative to the rotating assembly 20, thereby driving the lifting part 312 to move away from the rotating assembly 20 to a first predetermined position, so that the slip ring 200 is located within the connection range of the connecting assembly 40. Optionally, the force application part 321 can drive the transmission wheel 322a of each force transmission part 322 to rotate, and then the transmission wheel 322a engages with the teeth 311a on the mating part 311, so that the mating part 311 can move along the thickness direction X and move the slip ring 200 to a suitable position.

[0127] Connect the connecting component 40 to the slip ring 200.

[0128] The control drive component 32 drives the mating part 311 to move relative to the rotating assembly 20, thereby driving the hoisting part 312 to move towards the rotating assembly 20 to a second predetermined position, so that when the slip ring 200 rotates relative to the base 10, the components within the tower section 300 can give way to the slip ring 200. Optionally, the force application part 321 can be controlled to apply a reverse force, so that the hoisting part 312 drives the slip ring 200 as a whole to move towards the rotating assembly 20 to the second predetermined position.

[0129] In some alternative embodiments, before the step of adjusting the attitude of the nth tower section 300, the installation method provided in one embodiment of this application further includes locking the lifting drive assembly 30 to lock the degree of freedom of movement of the mating part 311 relative to the rotating assembly 20.

[0130] The control drive component 32 can drive the mating part 311 to move relative to the rotating component 20, thereby driving the hoisting part 312 to move towards the rotating component 20 to a second predetermined position, so that when the collector ring 200 rotates relative to the base 10, the components in the tower section 300 can give way to the collector ring 200 and lock the lifting drive component 30.

[0131] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
