Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to a transportation docking system for wind turbine installation. Background Art

[0002] As one of the most promising new energy sources with the largest scale of development and commercial development prospects, offshore wind power has developed rapidly in recent years as a form of clean energy, and its development scope has gradually expanded from shallow offshore to deep sea. Offshore wind turbines are devices that use ocean wind energy to convert into electrical energy. They are usually composed of wind turbine blades, nacelles, towers and foundations. Among them, the foundation is used to support the entire wind turbine to ensure its stability. The tower connects the foundation and the nacelle to support the nacelle and 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. 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 tower can be placed on the sea by lifting equipment, and then the climbing wind turbine installation assembly and 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 installation assembly. For specific reference, the technical solution disclosed in the Chinese utility model patent with the publication number CN219809090U and the patent name is a kind of installation device for offshore wind turbines. The climbing installation of wind turbines is mostly used on land, and the climbing wind turbine installation device is rarely used on offshore wind power installation platforms. It is difficult to transport and install the climbing equipment and the installed wind turbine nacelle components on the wind turbine tower. And as the power of wind turbines continues to increase, the difficulty of installation at sea is increasing, the cost is increasing, and it is difficult to ensure the safety of assembly.

[0005] Therefore, how to achieve low-altitude transportation docking and reduce the adverse effects of high-altitude operations is an important direction for continued research and development. Summary of the invention

[0069] At the same time, the adjustment component is easy to operate, and has high adjustment accuracy and good stability: by distributing the adjustment gears on both sides and arranging the adjustment racks along the length directions of the two, the distance adjustment of the first support plate and the second support plate can be achieved, which can ensure uniform distribution of force and reduce the tilt or deformation caused by excessive force on one side; at the same time, the design position of the adjustment rack ensures that during the adjustment process, the force is uniform and it can move smoothly, preventing jamming caused by unbalanced movement; and further enhances the accuracy of the adjustment, ensuring that the two support plates always remain parallel during adjustment.

[0070] Preferably, the conveyor ladder 21 is tilted upward in a direction away from the conveying seat 1, and an adjusting cylinder 223 for adjusting the angle of the conveying vehicle is provided at the end of the mobile seat 221, and one end of the adjusting cylinder 223 is connected to the mobile seat 221, and the other end is connected to an end of the conveying vehicle 222 close to the conveying seat 1. In this embodiment, the conveyor ladder 21 is provided with a conveyor belt 212 circulated in a vertical direction, and the slide seat is arranged on the conveyor belt 212, and moves along the surface of the conveying frame driven by the conveyor belt 212. In other optional embodiments, the conveying vehicle can also be driven by a linear drive device such as a screw rod and a motor to move along the conveyor ladder. Its specific setting method can be integrated on a rotating frame, or other setting methods that can realize this function.

[0071] In this embodiment, since the conveying ladder is inclined upward, the adjusting cylinder can maintain the horizontality of the conveying vehicle during transportation, so that the crawling fan installation device can be kept balanced, further enhancing the stability of transportation.

[0072] Preferably, a height adjustment device 7 is provided on the docking platform of the tower 30, and the height adjustment device 7 includes an adjustment plate 71 movably arranged on the docking platform, an adjustment drive mechanism 72 for driving the adjustment plate 71 to rise, fall or rotate, and an adjustment base 73 arranged on the top of the adjustment plate 71 for movably connecting with the conveying ladder 21; then, a compensation block 211 protruding toward the adjustment plate 71 is provided at the bottom of one end of the conveying ladder 21 close to the docking platform, and an adjustment groove 731 movably matched with the compensation block 211 is provided on the adjustment base 73; the compensation block 211 can be movably located in the adjustment groove 731 and does not separate from the adjustment groove 731. Specifically, a limiting boss or a movable connecting piece can be provided at the contact portion between the compensation block and the adjustment groove, so that the compensation block cannot leave the adjustment groove upward after entering the adjustment groove, and the present invention does not make specific restrictions on this.

[0073] Further explanation, preferably, the compensation block 211 is a hemispherical compensation block, and the adjustment groove 731 is a hemispherical adjustment groove 731 adapted to the compensation block 211. The soft connection formed by the hemispherical compensation block and the adjustment groove has a better compensation effect.

[0074] The adjustment drive mechanism 72 includes a base plate 721 disposed on the docking station and an adjustment bracket 722 mounted on the base plate 721 and movably connected to the adjustment plate 71; the adjustment bracket 722 includes a first adjustment rod 7221 and a second adjustment rod 7222 that are hinged in an X shape; the top end of the first adjustment rod 7221 is hinged on the adjustment plate 71, and the bottom end is slidably connected to the base plate 721; the top end of the second adjustment rod 7222 is slidably connected to the adjustment plate 71, and the bottom end is hinged on the base plate 721. In this embodiment, the advantage of such a design is that when the hemispherical compensation block and the height adjustment device are movably connected, a soft docking with the conveyor ladder compensation block is achieved, and the compensation block moves in the adjustment groove, so that it can adjust its position 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.

[0075] Furthermore, 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.

[0076] Preferably, two groups of the first adjusting rods and the second adjusting rods are respectively arranged on both sides below the adjusting plate; the adjusting drive mechanism includes a compensating cylinder 7223; the cylinder body of the compensating cylinder is fixed on the base plate, and its telescopic rod is connected to the upper part of the two second adjusting rods through a connecting rod 7224.

[0077] 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 goods on an offshore operating platform. This not only reduces the reliance on large lifting equipment, but also optimizes the advantages of low-altitude operations, effectively avoiding the wind resistance and shaking effects of high-altitude operations. At the same time, it has adaptive wave compensation capabilities to ensure balance and stability during transportation, significantly improving the efficiency of offshore operations.

[0078] Furthermore, the conveyor ladder assembly can adjust the vertical and horizontal angles respectively, and perform multi-angle wave compensation in real time, thereby enhancing the adaptability to ocean waves, keeping the conveyor frame stable, ensuring the stable transportation of goods, improving the safety of offshore operations, and maximizing the operation window period; in addition, the conveyor ladder assembly of the present invention is equipped with multi-point compensation of the height adjustment device, which can adapt to external force changes at any time, ensuring uniform and dispersed force transmission throughout the lifting and rotation process, effectively preventing structural damage to the conveyor ladder due to excessive external torque, and thus improving installation efficiency and reliability; the overall flexibility, convenience, practicality and other performance advantages of the transport docking system of the present invention, the operator does not need to perform complicated installation operations at high altitudes, meets the requirements of modern safe production, and provides a safer, more flexible and efficient solution for wind turbine installation, greatly reducing the cost of wind turbine installation.
