Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a conveying device and a conveying method for installing a fan. Background Art

[0002] As a clean and sustainable form of energy, offshore wind power has received widespread attention and rapid development in recent years. Compared with traditional onshore wind power, offshore wind power can utilize wind energy resources in vast sea areas, has higher power generation efficiency and is less restricted by terrain. With the increasing demand for global energy structure transformation, offshore wind power has become one of the main alternative energy sources. Offshore wind turbines are devices that convert ocean wind energy into electrical energy, usually consisting of wind turbine blades, nacelles, towers and foundations. Among them, the foundation is used to support the entire wind turbine to ensure its stability, and the tower connects the foundation with the nacelle to support the nacelle and the wind blades. The nacelle is located at the top of the tower and contains a generator, gearbox and control system, which is responsible for converting wind energy into electrical energy. The wind blades are fixed to the nacelle and are driven to rotate by wind energy, and the kinetic energy of the wind blades is converted into electrical energy through the transmission device.

[0003] As the cost of wind turbine towing becomes increasingly high, the method of offshore assembly and deployment is more common at this stage. The common method is that the floating wind turbine is disassembled into multiple modules such as wind turbine blades, nacelles, towers, etc., and transported to the designated deployment sea area by a self-elevating and self-propelled wind power installation ship. After the self-elevating wind power installation ship rises to a certain height above the sea level, the wind turbine module on the deck is lifted by a lifting device and connected and installed with the foundation pre-deployed on the sea level. Then, the wind turbine blades and nacelles are hoisted and installed on the top of the installed tower in turn, and finally the entire wind turbine is launched into the sea. The above assembly processes all rely on the high-altitude operation of the lifting device, especially the lifting operation of the wind turbine tower, which is longer and heavier, and needs to face greater impacts from sea breezes and waves.

[0004] In order to reduce the use of large lifting equipment, the foundation and the tower can be placed on the sea separately by lifting equipment, and then the climbing wind turbine installation assembly and the wind turbine blade nacelle assembly can be lifted to the lower section of the tower by lifting equipment, and the assembly of the wind turbine blade nacelle assembly can be completed by climbing the installation assembly. The specific reference is the technical solution disclosed in the Chinese utility model patent with publication number CN219809090U and patent name "A kind of offshore wind turbine installation device".

[0005] However, the climbing installation of wind turbines is mostly used on land, and is rarely used on deep-sea installation vessels. At the same time, although the climbing installation is beneficial to reduce high-altitude operations to a certain extent and reduce the adverse effects caused by high-altitude wind resistance, it is still necessary to transfer the climbing installation components from land to the installation vessel through lifting equipment, and then hoist them onto the tower. It is also necessary to complete the docking of the climbing installation components with the outer wall structure of the tower in the hoisting state, and it is also necessary to face the huge impact of wind resistance and shaking during the hoisting operation. It not only requires high coordination of equipment, but also requires precise control by operators. Any slight deviation may affect the overall docking accuracy, or even lead to docking failure, which in turn affects subsequent construction and makes it difficult to ensure the safety of assembly.

[0006] Therefore, how to achieve low-altitude transportation docking, reduce the adverse effects of high-altitude operations, and realize the stable transportation of climbing installation components from land to installation vessels and from installation vessels to towers is an important direction for continuous research and development.

[0042] Compared with the prior art, the present invention has at least the following beneficial effects:

[0043] 1. The conveying device of the present invention can flexibly adapt to various scenarios through the optimized combination of multiple structures such as the coordinated cooperation of multiple driving mechanisms, all-round flexible operation, and adaptive dynamic adjustment functions, and can achieve dynamic adjustment during the conveying process. It can also adapt well to the offshore installation environment, significantly improving the transportation efficiency and safety of climbing installation components between different environments;

[0044] Specifically, the conveying device of the present invention can meet the requirements of efficient movement of climbing installation components between land and offshore installation platforms and pre-installed towers. On the one hand, by docking the conveying ladder with the docking platform of the tower, the climbing installation components can be accurately transported to the tower and docked; in addition, after the installation of the wind turbine blade nacelle assembly is completed, the conveying device can also reverse the conveyor belt so that the slide and the conveying vehicle will move synchronously to the starting end of the conveying ladder, thereby realizing the recovery of the climbing installation components;

[0045] On the other hand, the conveyor ladder of the present invention can adjust the distance between the conveyor ladder and the land or platform as needed through the adjustment frame and the adjustment screw, so that the device can adapt to different environmental requirements. The adjustment frame and the adjustment screw, the third linear drive mechanism and the fourth linear drive mechanism can be flexibly adjusted in terms of the height difference and angle difference between the starting end and the docking end of the conveyor ladder, respectively, to ensure that the conveyor ladder can be accurately docked to the target position on the land, so that the conveyor device of the present invention can always remain stable during the conversion of different sites and heights.

[0046] 2. Another key design of the present invention is to realize the dynamic adjustment function in the conveying process through the cooperation of multiple mechanisms: first, when the conveying vehicle moves along the ladder surface, the conveyor belt drives the slide and the conveying vehicle to move synchronously, and the first driving cylinder will automatically adjust the angle between the conveying vehicle and the slide, so as to ensure the horizontal position and stability in the conveying process, and ensure the precise control in the conveying process, especially in the process of docking with the tower or the installation platform; secondly, in the face of unstable environmental factors of offshore installation, in order to better achieve precise docking with the tower, the present invention also fine-tunes the position of the slide by the second driving cylinder installed on the conveyor belt to improve the accuracy of docking; in addition, the third driving cylinder and the fourth driving cylinder respectively control the rotation of the conveying base and the adjustment frame, allowing the device to be adaptively adjusted in the horizontal and vertical directions, and can perform multi-directional compensation adjustment to ensure stable transportation and precise docking at all times;

[0047] 3. Furthermore, the multiple dynamic adjustment mechanisms of the present invention enable the conveying device of the present invention to achieve an efficient and stable operation cycle for the installation of climbing wind turbines; on the one hand, it is conducive to transferring the climbing installation assembly with the wind turbine nacelle blade assembly fixed to the offshore installation platform, and driving to the target tower position through the offshore installation platform, and the climbing installation assembly does not need to be transferred twice; on the other hand, after completing the transportation task from the offshore platform to the tower, the conveying device of the present invention can also realize the recovery of the climbing installation assembly after the wind turbine installation is completed, seamlessly connecting and reducing the dependence on large lifting equipment; especially in multiple cycles of use, the efficiency and flexibility of the device will greatly reduce the installation time and cost;

[0048] 4. The present invention uses flexible active connections and intelligent compensation mechanisms to adaptively adjust in a dynamic marine environment, ensuring that low-altitude operations can be performed when transporting climbing installation components on an offshore installation platform. This not only reduces dependence on large lifting equipment, but also optimizes the advantages of low-altitude operations, effectively avoiding the effects of wind resistance and shaking in high-altitude operations. At the same time, its adaptive wave compensation capability can adapt to external force changes at any time, ensuring uniform and dispersed force transmission throughout the entire lifting and rotation process, effectively preventing structural damage to the conveyor ladder due to excessive external torque, and improving installation efficiency and reliability.

[0084] To be further detailed, the upper part of the transport vehicle is provided with an adjustable first support plate 236 and a second support plate 237; the inner sides of the first support plate and the second support plate are respectively provided with the locking devices; the first support plate 236 and the second support plate 237 form a receiving cavity adapted to the base.

[0085] Specifically, the first linear drive mechanism, the second linear drive mechanism, the third linear drive mechanism, and the fourth linear drive mechanism are all drive cylinders in the prior art that meet the functions of the present invention.

[0086] Preferably, the cylinder body of the first driving oil cylinder is hinged to the second end of the slide 231, and the telescopic rod is hinged to the free end 2322 of the conveying vehicle 232. The telescopic rod extends and drives the free end 2322 of the conveying vehicle 232 to rotate with the hinged end 2321 as the axis, thereby increasing the rotation angle of the conveying vehicle 232 and the slide 231; the telescopic rod is retracted and drives the free end 2322 of the conveying vehicle 232 to rotate with the hinged end 2321 as the axis, thereby reducing the rotation angle of the conveying vehicle 232 and the slide 231; the rotation angle is 0-60°. In this embodiment, when the conveying vehicle moves along the ladder surface, the conveyor belt drives the slide and the conveying vehicle to move synchronously, and the first driving oil cylinder automatically adjusts the angle between the conveying vehicle and the slide, thereby ensuring the horizontal position and stability during the conveying process, and ensuring precise control during the conveying process, especially during the docking process with the tower or the installation platform.

[0087] Preferably, the cylinder body of the second driving oil cylinder is fixed on the mounting plate 233, the telescopic rod is connected to the slide 231, and the slide 231 can reciprocate under the drive of the telescopic rod. The position of the slide is fine-tuned by the second driving oil cylinder installed on the conveyor belt to improve the accuracy of docking.

[0088] Preferably, the locking assembly 32 includes a locking seat and a clamping member 321 arranged on the locking seat and capable of closing toward the limit block 3011 and clamping the limit block 3011, and a pressing member 322 capable of pressing the limit block 3011 onto the locking seat; and also includes a locking cylinder 323 for providing power to the clamping member 321 and the pressing member 322; a movable bottom plate 324 and a linkage plate 325 are provided at the end of the telescopic rod of the locking cylinder 323, and the linkage plate 325 is set through the middle of the movable base plate 324; the three clamping members 322 are evenly distributed on the movable base plate 324 along the circumference of the movable base plate 324; a clamping hook is provided at the end of the clamping member 322; the three clamping members 321 are evenly hinged and distributed on the linkage plate 325 along the circumference of the movable base plate 324, and are retracted toward the limit block 3011 and clamped on the edge of the limit block 3011 under the drive of the locking cylinder 323.

[0089] In this embodiment, through the linkage operation of the clamping member and the pressing member, combined with the ingenious design of the locking seat, the opening / closing of the clamping member and the pressing / relaxing of the pressing member are achieved simultaneously, completing the rapid clamping action of the limit block.

[0090] Preferably, a compensation device 4 is provided on the docking platform 50 of the tower 40, and the compensation device 4 includes a compensation plate 41 movably arranged on the docking platform 50, a driving component 42 for driving the compensation plate 41 to rise or fall or rotate, and a compensation seat 43 arranged on the top of the compensation plate 41 for movably connecting with the conveying ladder 22;

[0091] Specifically, the driving assembly 42 includes a bottom plate 421 disposed on the docking platform 50 and a compensation bracket 422 mounted on the bottom plate 421 and movably connected to the compensation plate 41; the compensation bracket 422 includes a first compensation rod 4221 and a second compensation rod 4222 that are hinged in an X shape; the top end of the first compensation rod 4221 is hinged on the compensation plate 41, and the bottom end is slidably connected to the bottom plate 421; the top end of the second compensation rod 4222 is slidably connected to the compensation plate 41, and the bottom end is hinged on the bottom plate 421; the bottom plate 421 is also provided with a compensation cylinder 4223 for driving the first compensation rod and the second compensation rod to provide power. The X-shaped movable hinged compensation bracket structure provides multi-directional support, so that the compensation plate remains stable during the lifting process, maintains good contact with the conveyor ladder, and ensures smooth contact between the two when docking.

[0092] The present invention drives the adjustment of the compensation seat through the movable compensation plate to achieve soft docking with the conveyor ladder, so that the position can be adjusted automatically according to changes in external conditions; at the same time, the flexibility of the compensation block and the guiding effect of the adjustment groove enable the compensation block to disperse the force when subjected to external force, thereby reducing damage caused by concentrated force.

[0093] Furthermore, a hemispherical compensation block 226 protruding toward the compensation plate 41 is provided at the bottom of one end of the conveying ladder 22 close to the docking platform 50, and an adjustment groove 431 movably matched with the compensation block 226 is provided on the compensation seat 43; the compensation block 226 can be movably located in the adjustment groove 431 and does not separate from the adjustment groove 431. The combination of the hemispherical compensation block and the adjustment groove effectively improves the stability and adaptability of the conveying device in the offshore environment. The compensation block can automatically adjust its position to resist the influence of waves and wind, ensuring the precise docking of the conveying ladder and the tower.

[0094] From the above description of the multiple compensation structures of the conveying base, rotating chassis and compensation device, it can be seen that the conveying device of the present invention has excellent adaptive compensation function in the conveying operation. By using the conveying base and rotating chassis, the horizontal and vertical cylinder settings can effectively adjust the vertical and horizontal directions and flexibly compensate and adjust functions according to the impact direction of the waves. Therefore, the vertical and horizontal multi-adjustment mechanism of the present invention can not only meet the alignment adjustment according to different operation scenes before the conveying operation, but also ensure dynamic compensation during the conveying process, killing two birds with one stone and having a clever design.

[0095] The present invention has the advantages of overall flexibility, convenience, practicality and other performances, and operators do not need to perform complicated installation operations at high altitudes, providing a safer, flexible and efficient solution for fan installation, thereby greatly reducing the cost of fan installation.

[0096] Example 2

[0097] like Figure 1-12 As shown, this embodiment 2 provides a method for conveying a conveying device for wind turbine installation as described above, wherein the operation of conveying the climbing installation assembly 30 located on the offshore wind power installation platform 10 to docking with the tower 40 includes the following steps:

[0098] Locking step: at the starting end 221 of the conveying ladder 22, the climbing installation assembly 30 with the blade nacelle assembly 20 fixed thereto is hoisted onto the conveying vehicle and fixed by the locking device; in this process, a hoisting device that meets the hoisting capacity can be used to perform the hoisting operation of the climbing installation assembly;

[0099] Conveying step: turning on the conveyor belt 223, and synchronously driving the slide 231 and the conveying vehicle 232 to move the climbing installation assembly 30 along the surface of the conveying ladder 22 toward the docking end 222 of the conveying ladder 22;

[0100] Docking step: The slide 231, the transport vehicle 232, and the climbing installation assembly 30 are transported to the docking end 222 of the conveyor ladder 22 driven by the conveyor belt 223, located above the docking platform 50 of the tower 40, and the distance between the slide 231 and the transport vehicle 232 and the end point, i.e., the docking part of the tower, is adjusted to complete the docking of the climbing installation assembly 30 and the tower 40. After the docking is completed, the operator performs a safety check to confirm that all connections are correct.

[0101] To further refine, in the conveying step, when the conveyor belt 223 synchronously drives the slide 231 and the conveying vehicle 232 to move along the conveying ladder 22 toward the docking end 222, the first linear drive mechanism 234 is controlled to synchronously increase the rotation angle of the free end 2322 and the hinged end 2321 of the conveying vehicle 232, thereby keeping the conveying vehicle 232 horizontal.

[0102] Specifically, in the conveying method of this embodiment 2, since the docking end of the conveying ladder is tilted upward relative to the starting end, the dynamic adjustment mechanism of the first linear drive mechanism enables the conveying vehicle to maintain a horizontal state, ensuring the smoothness and safety of the conveying operation; it can cope with different height differences, complex environments and dynamic changes.

[0103] Example 3

[0104] like Figure 1-11 As shown in FIG. 13 , this embodiment 3 provides a method for conveying a conveying device for wind turbine installation as described above, wherein the operation of conveying the climbing installation assembly 30 located on the tower 40 to the offshore wind power installation platform 10 includes the following steps:

[0105] Docking step: start the conveyor belt 223 to transport it toward the tower 40, and simultaneously drive the slide 231 and the transport vehicle 232 to be transported to the top of the docking platform 50 of the tower 40, and loosen the climbing installation assembly 30 from the tower 40, lower it to the locking plate 31 and fix it through the locking device;

[0106] Conveying step: turning on the conveyor belt 223 to convey the conveyor belt toward the starting end 221 of the conveyor ladder 22, and synchronously driving the slide 231 and the conveyor vehicle 232 to move the climbing installation assembly 30 along the surface of the conveyor ladder 22 to the starting end 221 of the conveyor ladder 22;

[0107] Disassembly step: loosen the locking device, and hoist the climbing installation assembly 30 to the target position.

[0108] To further refine, in the conveying step, when the conveyor belt 223 synchronously drives the slide 231 and the conveying vehicle 232 to move along the conveying ladder 22 toward the starting end 221, the first linear drive mechanism 234 is controlled to synchronously reduce the rotation angle of the free end 2322 and the hinged end 2321 of the conveying vehicle 232; thereby keeping the conveying vehicle 232 horizontal.

[0109] In the conveying step of the above-mentioned conveying method, the conveyor belt 223 is continuously operated, and the climbing installation assembly 30 can be smoothly conveyed along the surface of the conveying ladder 22 through the synchronous driving of the slide 231 and the conveying vehicle 232. The key is that during the conveying process, the first linear drive mechanism 234 is controlled to synchronously reduce the rotation angle of the free end 2322 and the hinged end 2321 of the conveying vehicle 232. This design ensures that the conveying vehicle 232 always remains horizontal, thereby effectively avoiding the deviation, swing or damage of the assembly caused by angle changes or unstable states.

[0110] Example 4

[0111] like Figure 1-11 As shown in FIG. 14 , this embodiment 4 provides a method for conveying a conveying device for wind turbine installation as described above, and the operation of conveying the climbing installation assembly 30 located on land 60 to an offshore wind power installation platform 10 includes the following steps:

[0112] Adjustment step: according to the distance between the offshore wind power installation platform 10 and the land 60, the driving motor 214 on the adjustment frame 21 is started, and the conveying ladder 22 is driven to move along the adjustment frame 21 through the adjustment screw 225 until the starting end 221 of the conveying ladder 22 reaches the target area where the climbing installation assembly 30 is located on the land 60;

[0113] Locking step: at the starting end 221 of the conveying ladder 22, the climbing installation assembly 30 with the blade nacelle assembly 20 fixed thereto is hoisted onto the conveying vehicle and fixed by the locking device;

[0114] Conveying step: starting the conveyor belt 223, synchronously driving the slide 231 and the conveying vehicle 232 to move the climbing installation assembly 30 along the surface of the conveying ladder 22 toward the docking end 222 of the conveying ladder 22, until it is transported to the designated position of the offshore wind power installation platform 10, i.e., the docking platform;

[0115] Disassembly steps: loosen the locking device, and hoist the climbing installation assembly 30 to the target position; and move the starting end 221 of the conveyor ladder 22 under the action of the driving motor 214 and the adjusting screw 225 in the adjustment step and recover it to the original state.

[0116] Through the adjustment steps of the above-mentioned conveying method, the flexibility of the conveyor ladder can quickly adapt to different working environments according to the distance between the offshore wind power installation platform and the land, thereby improving the installation efficiency. At the same time, the conveyor ladder can be quickly recovered to its original state after completing the operation, which provides convenience for subsequent operations and further improves the efficiency of the overall operation cycle.

[0117] From the conveying methods of Examples 2-4 of the present invention, it can be seen that the multiple dynamic adjustment mechanisms of the present invention enable the conveying device of the present invention to achieve an efficient and stable operation cycle for the installation of climbing wind turbines; on the one hand, it is conducive to transferring the climbing installation assembly with the wind turbine cabin blade assembly fixed to the offshore installation platform, and driving to the target tower position through the offshore installation platform, and the climbing installation assembly does not need to be transferred a second time; on the other hand, after completing the conveying task from the offshore platform to the tower, the conveying device of the present invention can also realize the recovery of the climbing installation assembly after the wind turbine installation is completed, seamlessly connecting and reducing dependence on large lifting equipment; especially in multiple cycles of use, the efficiency and flexibility of the device will greatly reduce installation time and cost.

[0118] In the present invention, it should be noted that the present invention can adopt sensors and control systems suitable for the present invention in the prior art to perform real-time monitoring and dynamic adjustment of various key parameters (such as angle, speed, load and environmental factors) in the operation process; such as angle sensors, position sensors, speed sensors, pressure sensors, etc.; the present invention does not elaborate on this.
