Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering equipment, in particular to a docking compensation device for installing a wind turbine. Background Art

[0002] With the rapid development of marine renewable energy, offshore wind power has also developed rapidly, and the scope of development has gradually expanded from shallow offshore to deep sea. Offshore wind turbines 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. The wind blades are fixed on the nacelle. As the offshore distance becomes larger and larger, the cost of deep-sea towing is also increasing. Therefore, it is more common to adopt the method of offshore assembly and delivery. That is, the wind turbine is disassembled into multiple modules such as wind turbine blades, nacelles, towers, etc., and assembled by wind power installation ships. In order to reduce the use of large lifting equipment, the foundation and the tower can be placed on the sea separately by the 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 the lifting equipment, and the assembly of the wind turbine blade nacelle assembly can be completed by the climbing installation assembly. For specific reference, the technical solution disclosed in the Chinese utility model patent with publication number CN219809090U and patent name is a device for installing an offshore wind turbine.

[0003] During wind turbine assembly, wind turbine installation vessels experience varying degrees of sway due to the effects of sea breezes and waves, making it difficult to stably transport and install the climbing equipment and installed wind turbine nacelle components onto the wind turbine tower. Platforms and rollers are currently being used for transport, but these conveying devices lack effective compensation structures. Waves can cause the vessel's hull to sway, which can easily damage the conveying device due to excessive external torque. This, combined with insufficient overall structural strength, leaves room for improvement in both transport stability and safety.

[0004] Therefore, further research and development is needed to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are at least in the following aspects:

[0018] 1. This utility model utilizes a dynamic adjustment mechanism of the compensation base and conveyor ladder, combined with a compensation plate assembly and drive mechanism. Through a flexible and efficient compensation structure design, it achieves effective vertical and horizontal adjustment and flexible compensation adjustment functions during the transportation and docking of the climbing wind turbine installation device with the tower during offshore wind turbine installation.

For example, the flexibility of the limit block and the guiding role of the adjustment slot can adapt to external force changes at any time, preventing the concentration of force caused by fixed position.

The linkage design between the compensation base and the conveyor ladder also enables vertical and horizontal adjustment. Overall, this can effectively reduce the damage to the conveyor ladder caused by torsional forces caused by hull sway, ensuring that the entire system can maintain a stable state under different environmental conditions.

[0023] 4.

[0036] In the description of the present invention, unless otherwise specified, the components used are conventional components in the prior art.

[0037] like Figure 1-8 As shown, the utility model provides a docking compensation device for wind turbine installation, which is used on a climbing offshore wind power installation ship to transport a climbing wind turbine installation device 10 with a blade nacelle assembly fixed thereon, and to complete the docking process of the climbing wind turbine installation device 10 and the tower 20; of course, the docking compensation device of the utility model can also be used in the assembly or docking process of other offshore work platforms, not limited to the various modules of the wind turbines listed above, as long as they can be adapted to the installation connection of the utility model.

[0039] In this embodiment, the tower can be pre-installed at sea by lifting equipment or other installation devices and has been fixed. The specific installation process will not be described in detail. In addition, the climbing wind turbine installation device 10 is used to place the wind turbine blade nacelle assembly. The climbing wind turbine installation device 10 and the tower are connected by a fixing structure and a driving structure to drive the wind turbine blade nacelle assembly to climb upward along the outer wall of the tower, and the installation of the wind turbine blade nacelle assembly is completed under the action of other equipment. For details, please refer to the technical solution disclosed in the Chinese utility model patent with publication number CN219809090U in the aforementioned content, and the patent name is a Chinese utility model patent for an installation device for an offshore wind turbine. This utility model is not limited to its operation method or structure.

[0040] In this embodiment, the climbing wind turbine installation device 10 is driven by power and transported along the conveyor ladder 2 to the end away from the compensation base 1 to complete the docking with the tower 20. The specific operation process and the devices involved are not limited by this utility model.

[0041] In further detail, the compensation plate assembly 3 includes a compensation plate 31 that can be raised and / or rotated and is arranged on the docking platform 201, a driving mechanism 32 for driving the compensation plate 31 to rise and fall, and a compensation seat 33 arranged on the compensation plate 31 for active cooperation with the conveyor ladder 2.

[0042] Preferably, a stop block 21 is provided at the bottom of the end of the conveyor ladder 2 that overlaps the docking station 201, protruding toward the compensation seat 33. The compensation seat 33 is provided with an adjustment slot 331 that flexibly cooperates with the stop block 21. The stop block 21 is movably located in the adjustment slot 331. In this embodiment, to further enhance the connection flexibility between the stop block and the adjustment slot, the stop block 21 is preferably hemispherical, and the adjustment slot 331 is a hemispherical adjustment slot 331 that matches the stop block 21. The adjustment slot 331 is provided with a limiting structure for preventing the stop block 21 from disengaging from the adjustment slot 331.

[0043] In this embodiment, the limiting structure can be a limiting protrusion arranged on the inner side of the adjustment groove, and the limiting block will be restricted by the limiting protrusion when it leaves the adjustment groove, so that it does not leave the adjustment groove; in other optional embodiments, the limiting structure can be other structures that meet the requirements of soft connection with the limiting block and can limit the limiting block from leaving the adjustment groove. The present utility model is not limited to this.

[0044] Preferably, the compensation plate assembly 3 includes a base plate 34 arranged on the docking platform 201 and a compensation bracket 35 installed on the base plate 34 and movably connected to the compensation plate 31, and the two ends of the compensation bracket 35 are movably connected to the base plate 34 and the compensation plate 31 respectively; the driving mechanism 32 is provided on the base plate 34, and the compensation bracket 35 is movably connected to the power output end of the driving mechanism 32.

[0045] The structure of the compensation bracket 35 is further explained in detail. The compensation bracket 35 includes a first support bar 351 and a second support bar 352 that are hinged in an X-shape. The top end of the first support bar 351 is hinged to the compensation plate 31, and the bottom end is slidably connected to the bottom plate 34. The top end of the second support bar 352 is slidably connected to the compensation plate 31, and the bottom end is hinged to the bottom plate 34. The driving mechanism 32 includes a first compensation cylinder 321, the cylinder body of the first compensation cylinder 321 is hinged to the bottom plate 34, and the end of its telescopic rod is hinged to the first support bar 351 or the second support bar 352.

[0046] In this embodiment, the flexibility of the limit block and the guiding function of the adjustment groove can adapt to the changes in external forces at any time and prevent the concentration of forces caused by the fixed position; combined with the ingenious connection design of the compensation bracket and the drive mechanism, it ensures that the force is transmitted evenly and dispersedly during the entire lifting and rotation process, which can effectively reduce the impact of the torsional force caused by the shaking of the hull on the conveyor ladder.

[0047] To achieve a more balanced force distribution, preferably, two sets of compensation brackets 35 are respectively disposed on either side between the compensation plate 31 and the base plate 34, and the two first support bars 351 or the second support bars 352 are connected by a crossbar 36. The telescopic rods of the two first compensation cylinders 321 are respectively hinged to the crossbar 36. Generally, in this embodiment, the crossbar is disposed between the upper portions of the two first support bars 351. When the telescopic rods of the first compensation cylinders are extended, they push the crossbar to drive the compensation brackets up and down.

[0048] Preferably, a guide rod 37 is respectively provided on the compensation plate 31 and the base plate 34; the bottom ends of the two first support bars 351 are respectively connected to the guide rod 37 on the base plate 34 by a sliding sleeve through a hinge seat 353, and the top ends of the two second support bars 352 are respectively connected to the guide rod 37 of the compensation plate 31 by a hinge seat 353; the hinge seats 353 at the bottom ends of the two first support bars 351 are connected by a connecting rod 38; a second compensation cylinder 322 is provided on the base plate 34, and the connecting rod 38 is fixed to the end of the telescopic rod of the second compensation cylinder 322.

[0049] Specifically, in this embodiment, the second compensating cylinder functions to cause the connecting rod and articulated seat to slide when compensation adjustment is required, by extending and retracting the telescopic rod. This alters the rotational support state of the first and second support bars in the X-shaped arrangement, achieving vertical adjustment of the compensating plate. This embodiment enables precise vertical adjustment of the compensating plate. The sliding coordination of the articulated seat and guide rod ensures smooth movement of the support bars, reducing instability associated with adjustment.

[0050] In this embodiment, the movable compensation plate drives the adjustment of the compensation seat to achieve soft docking with the conveyor ladder limit block. The limit 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 limit block and the guiding effect of the adjustment groove enable the limit block to disperse the force when it is subjected to external force, reducing damage caused by concentrated force.

[0051] 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 during docking.

[0052] Not only that, the present invention also provides vertical and horizontal compensation structures at the end of the conveying ladder away from the tower. Preferably, the compensation base 1 is movably installed on the offshore wind power installation ship through a rotating chassis 4 that can rotate in the horizontal direction. The two sides of the rotating chassis 4 are respectively provided with a first rotating cylinder 41 for driving the compensation base 1 to rotate; the ends of the telescopic rods of the two first rotating cylinders 41 are respectively hinged to the outer walls on both sides of the compensation base 1.

[0053] To be further refined, the conveyor ladder 2 is movably mounted on the compensation base 1 through a rotating frame 5 that can rotate in the vertical direction; a second rotating cylinder 51 is provided at the bottom of the rotating frame 5 for driving the rotating frame 5 to rotate in the vertical direction; the ends of the telescopic rods of the two second rotating cylinders 51 are respectively hinged to the bottom of the rotating frame 5.

[0054] The compensation base of the utility model performs horizontal rotation compensation through a rotatable rotating chassis, and the conveyor ladder is installed through a vertical rotating frame to perform vertical compensation adjustment in real time. The linkage design between the compensation base and the conveyor ladder also realizes vertical and horizontal adjustment. The overall design can effectively reduce the damage to the conveyor ladder caused by the torsional force caused by the shaking of the hull, and can ensure that the entire system can maintain a stable state under different environmental conditions.

[0055] The utility model utilizes the dynamic adjustment mechanism of the compensation base and the conveying ladder, combines the compensation plate assembly and the driving mechanism, and realizes the effective adjustment and flexible compensation adjustment functions in the vertical and horizontal directions during the transportation of the climbing wind turbine installation device and the docking of the climbing wind turbine installation device with the tower through a flexible and efficient compensation structure design during the installation of offshore wind turbines. It can adapt to various height differences and inclination angles, and ensure the transportation and docking stability and safety of the climbing wind turbine installation device; at the same time, it effectively prevents the structural damage of the conveying ladder due to excessive external torque, thereby improving the installation efficiency and reliability.

[0056] To sum up, the docking compensation device of the utility model has dynamic adaptability, reduces the potential dangers caused by operational delays, ensures the stable and safe transportation of the climbing wind turbine installation device, further improves the reliability and efficiency of the entire installation operation, and has strong overall flexibility, practicality and high safety performance.
