Description

Technical Field

[0001] This application relates to the field of offshore wind farm meteorological towers, and in particular to a suction jacket foundation structure for offshore wind farm meteorological towers. Background Technology

[0002] Offshore wind farms, as an important component of renewable energy, have experienced rapid development globally in recent years. In the construction of offshore wind farms, meteorological towers play a crucial role, primarily collecting meteorological data such as wind speed and direction to provide key information for site selection, design, and operation. However, because offshore wind farms are typically located far from shore with complex and variable geological conditions, the design of meteorological tower foundations places extremely high demands on their design. To ensure the stability and safety of these towers, related technical fields have been continuously exploring and optimizing foundation types.

[0003] Currently, the commonly used foundation types for wind measurement towers in the industry mainly include traditional structures such as monopile foundations, high-pile caps, and four-pile jacket structures. These foundation types support the wind measurement tower by driving or fixing it to the seabed. Specifically, monopile foundations use a single large steel pipe pile driven directly into the seabed, suitable for shallower water depths and hard foundations; high-pile caps combine multiple steel pipe piles with a concrete cap, suitable for more complex geological conditions; and four-pile jacket structures use multiple steel pipes combined to form a frame structure, providing stronger load-bearing capacity. Although these foundation types meet the usage requirements of wind measurement towers to a certain extent, they still present many challenges in terms of construction difficulty, cost control, and environmental impact.

[0004] The aforementioned traditional foundation types often exhibit insufficient applicability when facing soft soil foundations. For example, in soft soil foundations such as silty clay or silty mud, single-pile foundations are prone to settlement, high-pile caps are complex and costly to construct, and four-pile jackets may exert excessive pressure on the foundation due to their large self-weight. Therefore, developing a wind measurement tower foundation type that is suitable for soft soil foundations, easy to construct, and environmentally friendly has become an urgent technical problem to be solved. Summary of the Invention

[0005] To facilitate the installation and construction of jacket foundations, this application provides a suction-type jacket foundation structure for use in offshore wind farm anemometer towers.

[0006] The suction jacket foundation structure for offshore wind farm anemometer towers provided in this application adopts the following technical solution:

[0007] A suction jacket foundation structure for a wind measurement tower in an offshore wind farm includes a jacket body, several suction tanks, and a pumping device communicating with the interior of the suction tanks. The suction tanks are located at the bottom of the jacket body with their openings facing downwards. When the jacket body is submerged and installed, the pumping device is used to extract water from the suction tanks to create a negative pressure effect.

[0008] By adopting the above technical solution, this suction jacket foundation structure is effectively suited to the construction requirements of anemometer towers in offshore wind farms. By installing several downward-facing suction tanks at the bottom of the jacket body and using a pumping device to extract water from the tanks to create a negative pressure effect, the jacket foundation can be rapidly and stably lowered into soft soil, significantly reducing construction difficulty and cost. This design eliminates the need for large-scale excavation and backfilling, minimizing the impact on the marine ecosystem and demonstrating excellent environmental performance. Furthermore, the introduction of the negative pressure effect enhances the bonding force between the suction tanks and the foundation, improving the foundation's bearing capacity and the overall structural stability, ensuring the safe operation of the anemometer tower under extreme weather conditions.

[0009] Preferably, the main body of the catheter frame includes a plurality of main tubes and a support tube connecting the plurality of main tubes. The lower ends of the plurality of main tubes expand outward from the main body of the catheter frame, and the plurality of suction buckets are disposed at the lower ends of the plurality of main tubes.

[0010] By adopting the above technical solution, the jacket structure is composed of several main pipes and support pipes. The lower ends of the main pipes expand outwards and are correspondingly installed with suction tanks, effectively improving the overall stability and load-bearing capacity of the jacket structure. Simultaneously, the expansion design at the lower ends of the main pipes enhances the stability of the jacket structure. Furthermore, the support pipes further strengthen the rigidity of the jacket structure, ensuring its wind, wave, and current resistance in complex marine environments, thus providing a more stable foundation support for the wind measurement tower.

[0011] Preferably, the pumping device includes an installation platform disposed on the top surface of one of the suction barrels, a suction pump assembly disposed on the installation platform, and several pipelines connected to the suction pumps, wherein the several pipelines are respectively connected to the interior of each suction barrel.

[0012] By adopting the above technical solution, the installation platform provides a stable foundation for the suction pump unit, ensuring reliable operation of the pumping device in complex marine environments. The suction pump unit is connected to the interior of each suction tank via pipelines, enabling efficient water extraction from the tanks to create a stable negative pressure effect, thereby driving the tanks to quickly sink into the soft soil foundation. This design significantly improves the efficiency and stability of the sinking installation, while reducing disturbance to the surrounding soil, lowering construction costs, and minimizing environmental impact.

[0013] Preferably, a plurality of vertical plates are connected between the periphery of the main guide tube and the top surface of the suction barrel, and the plurality of vertical plates are perpendicular to the top surface of the suction barrel.

[0014] By adopting the above technical solutions, the installation of the upright plate effectively enhances the connection strength between the main pipe and the suction tank, ensuring a stable connection when subjected to external loads. The design of the upright plate perpendicular to the top surface of the suction tank further optimizes the stress distribution and improves the shear resistance of the overall structure, thereby enhancing the stability and reliability of the jacket foundation structure in complex marine environments.

[0015] Preferably, stiffening ribs are provided between adjacent upright plates.

[0016] By adopting the above technical solution, the stiffening ribs effectively enhance the connection strength between the vertical plates and improve the overall structural stability. In the complex and variable environment of offshore wind farms, this design can significantly improve the ability of the jacket foundation structure to resist lateral loads, reduce structural deformation caused by external environmental factors, and thus ensure the long-term reliability and safety of the wind measurement tower foundation.

[0017] Preferably, a first ring plate is provided on the outer periphery of the main tube, located above the vertical plate, and the tops of several vertical plates converge and are fixed towards the bottom surface of the first ring plate.

[0018] By adopting the above technical solution, a first ring plate is installed around the outer periphery of the main pipe, and the top of the vertical plate is gathered and fixed to the bottom surface of the first ring plate. This design significantly improves the overall stability of the jacket structure. Specifically, the first ring plate, as a connector, effectively enhances the connection strength between the main pipe and the suction tank, allowing both to transmit stress more evenly when bearing external loads, avoiding structural failure caused by localized stress concentration. Furthermore, this connection method also improves the jacket's resistance to lateral loads, ensuring its long-term reliability in complex marine environments.

[0019] Preferably, a plurality of reinforcing plates are connected between the periphery of the main tube and the top surface of the first ring plate, and the reinforcing plates are perpendicular to the top surface of the first ring plate.

[0020] By adopting the above technical solution, several reinforcing plates perpendicular to the top surface of the first ring plate are installed between the main pipe and the first ring plate, enhancing the structural strength at the connection between the main pipe and the first ring plate and improving the overall structural stability. This design effectively prevents deformation or damage at the connection between the main pipe and the first ring plate under the action of external forces such as wind, waves, and currents in the marine environment, thereby extending the service life of the jacket foundation structure. At the same time, the installation of reinforcing plates also optimizes the force transmission path, enabling the entire structure to bear external loads more evenly, further improving the reliability and safety of the jacket foundation structure.

[0021] Preferably, a base platform is provided on the top of the guide frame body, and the tops of several main tubes extend through the base platform, with lifting lugs provided on the inner side of the top of each main tube.

[0022] By adopting the above technical solution, a foundation platform is set at the top of the jacket structure to provide an installation positioning benchmark for the main conduits, ensuring the overall stability and reliability of the structure. Several main conduits penetrate the foundation platform at the top, enhancing the stability of the structural connections and providing a uniform distribution of support force. Lifting lugs are installed on the inner side of the top of the main conduits, providing convenient operating points for subsequent hoisting operations, improving construction efficiency and reducing construction difficulty. This design optimizes the construction process and enhances the practicality and safety of the overall structure.

[0023] Preferably, a ladder is provided on the outer side of the main body of the jacket, the upper end of the ladder extends to the foundation platform, the lower section of the ladder is provided on both sides with mooring posts, and a protective cage is provided at the lower section of the ladder, the protective cage extending along the length of the ladder into the foundation platform.

[0024] By adopting the above technical solutions, the ladder configuration provides workers with access to and from the main structure of the guide frame, improving operational convenience. The placement of the ship-supporting pillars effectively protects the lower section of the ladder from collision damage when ships approach, enhancing structural safety. The extended design of the safety cage provides comprehensive protection for workers during the climbing process, preventing accidental falls, which is especially important in inclement weather conditions. Furthermore, the safety cage extends from the lower section of the ladder into the foundation platform, further increasing the protection range and ensuring the safety of workers approaching the work area.

[0025] Preferably, the jacket body is provided with anti-collision posts, and the anti-collision posts and the mooring posts are located on the same side of the jacket body.

[0026] By adopting the above technical solution, the main body of the jacket is provided with anti-collision posts, and the anti-collision posts and the mooring posts are located on the same side of the main body of the jacket.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By combining the main body of the jacket with the suction tank and using a pumping device to extract water from the suction tank to create a negative pressure effect, the foundation can be quickly and stably sunk into the soft soil foundation, significantly improving construction efficiency and reducing construction costs.

[0029] 2. The main body of the jacket is made of high-strength steel, and through measures such as optimizing the structural layout and adding reinforcing ribs, the rigidity and strength of the overall structure are ensured, effectively resisting the influence of marine environmental factors such as wind, waves, and currents, and ensuring the stability and safety of the wind measurement tower;

[0030] 3. The suction-type sinking installation technology avoids large-scale excavation and backfilling operations in traditional construction methods, reducing damage to the marine ecological environment. At the same time, the negative pressure can also compact soft soil foundations and improve the bearing capacity of the foundation, which has significant environmental protection and energy-saving advantages.

[0056] S3, the pumping device 3 extracts water from the suction tank 2, creating a negative pressure effect, which allows the suction tank 2 to sink quickly and stably into the foundation. The pumping device 3 employs highly efficient and energy-saving pumping technology to ensure the rapid and stable sinking process.

[0057] S4. During the sinking process, the positioning device is used to monitor the position of the guide frame and suction tank 2 in real time to ensure that they are accurate.
