Description

Technical Field

[0001] This utility model relates to the field of offshore wind power installation equipment, and in particular to a large-scale wind power auxiliary installation platform. Background Technology

[0002] With the trend of offshore wind power moving towards large-capacity units, the installation of large wind turbine foundations faces significant technical bottlenecks. Traditional offshore installation platforms, due to insufficient structural strength, struggle to accurately control their attitude in complex marine environments such as strong winds, high currents, and tidal changes, resulting in difficulty in ensuring foundation installation accuracy. The verticality error of large-capacity foundations often exceeds the standard, weakening the long-term load-bearing capacity of the structure. In addition, conventional platforms have limited functions, focusing only on foundation hoisting and transportation, lacking the ability to construct dry working environments, and failing to isolate seawater from the corrosion of the foundation installation surface. The connection section between the foundation and the tower of large-capacity units has high requirements for dryness and cleanliness. Seawater infiltration can cause problems such as steel structure corrosion and grout adhesion failure, seriously affecting the foundation connection strength and overall stability. Traditional installation platforms cannot simultaneously ensure high-strength load-bearing capacity and stable construction in dry working environments, and it is even more difficult to achieve automated collaborative operations between multiple systems, resulting in low installation efficiency and failing to meet the urgent needs of large-scale offshore wind power development.

[0003] Therefore, those skilled in the art have provided a large-scale wind power auxiliary installation platform to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by achieving efficient and stable offshore wind power foundation installation through innovative floating positioning and dry operation linkage. During the transportation phase, the platform relies on the main buoy and four extended auxiliary buoys at the corners to provide sufficient buoyancy, allowing it to safely float on the sea surface for long-distance transport. The auxiliary buoys expand the buoyancy area and enhance the platform's stability against wind and waves. Upon arrival at the installation area, the platform enters the positioning phase. The four support anchors, driven by the drive motors, rapidly descend through gear and rack meshing. Their bottom anchor tips are designed with sharp points to quickly penetrate the seabed, using the reaction force to lift the main buoy out of the water. Each motor is housed in an independent, sealed, waterproof box to prevent seawater intrusion, thus avoiding short circuits or core corrosion. The guide cavity inside the anchor fixing sleeve provides precise guidance and positioning for the anchors, in conjunction with the limiting position at the top of the anchors. To prevent excessive displacement and ensure stable platform levitation, the platform effectively resists wave impact and provides a stable base for subsequent installation. Entering the dry operation phase, the dry installation chamber at the center of the main pontoon is vertically lowered to the seabed via gear and rack transmission driven by a drive motor. The adaptive sealing gasket at the bottom of the chamber closely conforms to the seabed topography, forming a reliable waterproof barrier. Subsequently, the chamber's drainage pump quickly pumps out the internal seawater, creating a dry environment within the working chamber and completely isolating it from the impact of seawater on wind turbine foundation installation. This dry operation mode avoids seawater corrosion of the steel structure and eliminates the adverse effects of seawater on concrete grouting, component welding, and other processes, significantly improving the foundation connection strength and durability. Simultaneously, it eliminates the need for diving operations or complex waterproofing measures, greatly simplifying the construction process. Combined with multi-system automated collaborative control, it achieves highly efficient operation throughout the entire process from positioning to installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A large-scale wind power auxiliary installation platform includes a main float box. A cavity fixing sleeve is fixedly installed at the center of the main float box. A cavity guide slide cavity is formed inside the cavity fixing sleeve. Four waterproof boxes are symmetrically fixedly installed on the surface of the main float box along the cavity fixing sleeve. A cavity drive motor is fixedly installed inside each waterproof box. A dry installation cavity is inserted into the cavity guide slide cavity. A working chamber is formed inside the dry installation cavity. Four cavity gear guide grooves are symmetrically formed on the surface of the dry installation cavity. An adaptive sealing gasket is fixedly installed at the bottom of the dry installation cavity. A cavity drainage pump is fixedly installed on the surface of the dry installation cavity. A secondary buoy extends from the center of each of the four sides of the main buoy. An anchoring column fixing sleeve is fixedly installed on each secondary buoy. An anchoring column guide cavity is opened inside each anchoring column fixing sleeve. Two waterproof boxes are symmetrically fixedly installed on the surface of each secondary buoy along the anchoring column fixing sleeve. Two anchoring column drive motors are fixedly installed inside each waterproof box. A supporting anchoring column passes through each anchoring column guide cavity. An anchoring column gear guide grooves are opened on both sides of each supporting anchoring column.

[0007] Through the above technical solution, a precise guiding structure for the dry installation cavity is formed by setting a cavity fixing sleeve and a cavity guide slide in the center of the main buoy box. This, combined with cavity drive motors symmetrically arranged inside waterproof boxes, ensures reliable motor drive of the dry installation cavity as it rises and falls vertically along the cavity guide slide, thanks to the waterproof box's sealing and protection against seawater erosion. The self-adaptive sealing gasket at the bottom of the dry installation cavity works in conjunction with the cavity drainage pump on the surface. When lowered to the seabed, the gasket conforms to the terrain to form a waterproof barrier, and the drainage pump pumps out the internal seawater, creating a dry working environment within the operating cavity. This dry installation mode avoids seawater corrosion of the wind turbine foundation steel structure, eliminates the impact of seawater on concrete grouting and component welding processes, significantly improves foundation connection strength and durability, and eliminates the need for submersion. Water-based operations or complex underwater protective measures simplify the construction process, reduce safety risks, and provide land-like operating conditions for offshore wind power foundation installation, ensuring installation accuracy and efficiency. The auxiliary buoys extending from the main buoy are fixed with anchoring column fixing sleeves and anchoring column guide cavities. Symmetrically arranged waterproof boxes house anchoring column drive motors, which drive the support anchoring columns to move up and down along the anchoring column guide cavities. When the support anchoring columns are inserted into the seabed, the reaction force lifts the main buoy out of the water surface. The anchoring column gear guide grooves on its surface mesh with the drive system, precisely controlling the lifting stroke and platform attitude. Combined with the dry installation cavity, this achieves dry, high-precision installation of offshore wind power foundations, fundamentally solving problems such as shortened foundation lifespan and insufficient installation accuracy caused by seawater erosion in traditional underwater operating environments.

[0008] Furthermore, each of the cavity drive motors is rotatably connected to a cavity motor drive shaft, and each cavity motor drive shaft passes through a cavity fixing sleeve and is fixedly connected to a cavity gear.

[0009] With the above technical solution, each cavity drive motor is rotatably connected to the cavity motor drive shaft, and each cavity motor drive shaft passes through the cavity fixing sleeve and is fixedly connected to the cavity gear, forming a synchronous drive structure. When the motor starts, the drive shaft transmits torque to the cavity gear, and the gear meshes with the rack fixed on the surface of the dry-mounted cavity, driving the cavity to rise and fall smoothly along the guide slide.

[0010] Furthermore, each of the anchoring post drive motors is rotatably connected to the anchoring post motor drive shaft, and each of the anchoring post motor drive shafts passes through the anchoring post fixing sleeve and is fixedly connected to the anchoring post gear.

[0011] Through the above technical solution, each anchoring post drive motor is rotatably connected to the anchoring post motor drive shaft, and each anchoring post motor drive shaft passes through the anchoring post fixing sleeve and is fixedly connected to the anchoring post gear, forming a symmetrical double gear drive structure. When the motor starts, the drive shaft transmits power to the anchoring post gear, and the gear meshes with the rack supporting the surface of the anchoring post, driving the anchoring post to move up and down precisely along the guide slide cavity.

[0012] Furthermore, a cavity rack is fixedly provided on one side of each of the four cavity gear guide grooves, and the four cavity gear guide grooves mesh with the four cavity gears on the inner wall of the cavity fixing sleeve.

[0013] Through the above technical solution, a cavity rack is fixedly installed on one side of each of the four cavity gear guide grooves. The four cavity gear guide grooves mesh with the four cavity gears on the inner wall of the cavity fixing sleeve, forming a four-gear synchronous transmission structure. When the cavity drive motor drives the cavity gears to rotate, the four gears, through meshing with the cavity racks, synchronously drive the dry installation cavity to rise and fall along the cavity guide slide. This structure distributes the force evenly through multiple gears, dispersing the lateral force during the cavity lowering process to four meshing points, ensuring uniform contact between the sealing gasket at the bottom of the working cavity and the seabed surface, avoiding sealing failure due to skew. At the same time, the four-gear transmission system has higher transmission rigidity and can withstand the impact load during cavity lowering.

[0014] Furthermore, an anchoring column rack is fixedly provided on one side of each anchoring column gear guide groove, and each anchoring column gear guide groove meshes with two anchoring column gears on the inner wall of the anchoring column fixing sleeve. An anchoring column tip is fixedly provided at the bottom of each supporting anchoring column, and a limiting plate is fixedly provided at the top of each supporting anchoring column.

[0015] Through the above technical solution, an anchoring column rack is fixedly installed on one side of each anchoring column gear guide groove. Each guide groove meshes with two anchoring column gears on the inner wall of the anchoring column fixing sleeve, forming a double-gear synchronous transmission structure. When the anchoring column drive motor drives the anchoring column gear to rotate, the double gears, through meshing with the anchoring column rack, synchronously drive the support anchoring column to rise and fall along the guide slide cavity. This structure distributes the lateral force when the anchoring column is inserted into the seabed to two meshing points through the uniform force of the double-sided gears, avoiding the platform tilting from affecting the installation accuracy. The anchoring column tip fixed at the bottom of each support anchoring column adopts a tapered and sharpened design to quickly cut into the seabed rock layer or soft soil. The limiting plate set at the top of the support anchoring column cooperates with the limiting groove at the top of the anchoring column fixing sleeve. When the anchoring column rises to the preset height, the limiting plate can block the motor drive signal in real time to prevent the anchoring column from being excessively raised and detached from the guide slide cavity.

When the support anchoring column 11 is inserted into the seabed, it lifts the main buoy 1 out of the water surface by reaction force. The anchoring column gear guide groove 9 on its surface meshes with the drive system to precisely control the lifting stroke and platform attitude. Together with the dry installation cavity 3, it realizes the dry high-precision installation of offshore wind power foundations, fundamentally solving the problems of shortened foundation life and insufficient installation accuracy caused by seawater erosion in traditional underwater operating environments.
