Description

Technical Field

[0001] This application relates to the field of offshore wind power construction, and in particular to the main structure of an offshore wind power pile driving guide frame stabilization platform. Background Technology

[0002] Offshore wind turbine pile driving guide and stabilization platforms are crucial equipment in marine engineering, widely used in the foundation construction of offshore wind power plants. With the increasing global demand for renewable energy, the development of offshore wind power projects is growing, leading to increasingly higher requirements for related construction equipment. The main function of these platforms is to provide stable support for the precise installation of steel pipe piles in the underwater environment, ensuring construction quality and efficiency. Therefore, a well-designed and reliable offshore wind turbine pile driving guide and stabilization platform is of great significance for ensuring the smooth progress of projects.

[0003] Currently, to adapt to different water depth conditions, commonly used offshore wind turbine pile driving guide frames and stabilization platforms mainly include two types: fixed and mobile. Fixed pile stabilization platforms are typically composed of steel structures and are fixed to the seabed through embedded parts or anchoring devices, suitable for areas with relatively small water depth variations. Mobile pile stabilization platforms, on the other hand, are more flexible and can adapt to different water depth environments by adjusting the platform height. Common methods include using hydraulic cylinders to achieve height adjustment.

[0004] However, existing offshore wind turbine pile driving guide frame stabilization platforms have certain limitations in practical applications. Especially when facing significant water depth variations, traditional fixed platforms struggle to quickly adjust their height, resulting in poor applicability and flexibility. While some mobile platforms can increase their overall height by adding extension sections, this often requires complex assembly and debugging, increasing construction difficulty and cost. Long-term use also raises concerns about platform stability and safety. These issues limit the effectiveness of existing platforms in complex marine conditions, necessitating a more efficient and reliable technological solution for improvement. Summary of the Invention

[0005] To adapt to different sea depth conditions, this application provides a main structure for an offshore wind power pile driving guide frame stabilization platform.

[0006] The main structure of the offshore wind power pile driving guide frame stabilization platform provided in this application adopts the following technical solution:

[0007] A main structure of an offshore wind power pile driving guide frame stabilization platform includes a frame and a working platform detachably connected to the top of the frame. The connection between the working platform and the frame can be extended by adding vertical steel pipes to increase the overall height of the main structure of the guide frame stabilization platform.

[0008] By adopting the above technical solution, the height of the main structure of the guide frame stabilizing platform can be flexibly adjusted by adding vertical steel pipes, thereby adapting to different sea depth conditions and ensuring smooth pile driving operations during construction. At the same time, this design also improves the stability and reliability of the platform, reducing construction risks and costs caused by changes in water depth.

[0009] Preferably, the frame includes several vertically arranged main leg steel pipes and several connecting steel pipes, the connecting steel pipes being connected between adjacent main leg steel pipes, and the main leg steel pipes being used for the insertion of auxiliary piles for positioning.

[0010] By adopting the above technical solution, the frame consists of several vertically arranged main leg steel pipes and connecting steel pipes. The connecting steel pipes connect adjacent main leg steel pipes, ensuring the stability and strength of the frame. At the same time, the main leg steel pipes can be used for the insertion of auxiliary piles for positioning, improving the accuracy and stability of the main structure of the guide frame stabilization platform during construction.

[0011] Preferably, the working platform includes a rectangular frame and a number of support steel pipes placed at the corners of the rectangular frame, with each of the support steel pipes corresponding to and connected to the other.

[0012] By adopting the above technical solution, the working platform includes a rectangular frame and several support leg steel pipes located at the corners of the rectangular frame. These support leg steel pipes correspond one-to-one with and are connected to the main leg steel pipes, making the entire working platform more stable. This design not only improves the overall rigidity and stability of the platform, but also facilitates installation and disassembly, adapting to the construction needs of different sea areas.

[0013] Preferably, annular connecting plates are provided at the lower end of the outrigger steel pipe and the upper end of the main leg steel pipe, and detachable fasteners are provided between the annular connecting plates of the outrigger steel pipe and the main leg steel pipe.

[0014] By adopting the above technical solutions, rapid installation and disassembly between the outrigger steel pipes and the main leg steel pipes can be achieved, improving on-site construction efficiency. Meanwhile, the design of the annular connecting plate makes the connection more stable and reliable, enhancing the safety of the entire guide frame stabilizing platform's main structure. The application of detachable fasteners also facilitates later maintenance and adjustments, adapting to the needs of different marine environments.

[0015] Preferably, the rectangular frame has several horizontal support members inside.

[0016] By adopting the above technical solutions, the rigidity and stability of the rectangular frame are increased, effectively preventing the work platform from deforming or tilting during construction, thus ensuring the safety of workers and the quality of construction.

[0017] Preferably, each corner of the rectangular frame is provided with an extension platform, and the extension platform is provided with a clearance for the steel pipe pile to pass through vertically. The far end of the clearance extends away from the center of the rectangular frame and is provided with an opening.

[0018] By adopting the above technical solution, extension platforms are set at each corner of the rectangular frame. These extension platforms provide a larger working space, facilitating operation by construction personnel and placement of equipment. Simultaneously, the extension platforms are equipped with clearance spaces for the vertical passage of steel pipe piles, allowing them to pass smoothly without obstruction and improving installation efficiency. The distal end of the clearance space extends away from the center of the rectangular frame and is open, further increasing the clearance range and ensuring smooth insertion of steel pipe piles at different positions, enhancing the adaptability and stability of the guide frame's pile stabilization platform.

[0019] Preferably, the bottom of the frame is provided with a horizontal anti-sinking plate, and the anti-sinking plate is provided with several through holes.

[0020] By adopting the above technical solutions, the anti-sinking plate can effectively prevent the frame from sinking in the soft soil layer of the seabed, ensuring the stability of the stabilizing platform. Several through holes on the anti-sinking plate can reduce water flow resistance, improving installation efficiency and stability.

[0021] Preferably, a diagonal bracing pipe is provided between the anti-sinking plate and the main leg steel pipe.

[0022] By adopting the above technical solutions, the stability between the anti-sinking plate and the main leg steel pipes is increased, effectively preventing the anti-sinking plate from sinking and shifting on the seabed, and improving the stability and safety of the entire guide frame stabilizing platform's main structure. The design of the diagonal bracing pipes further enhances the rigidity of the frame, ensuring stable operation in complex marine environments.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0029] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0030] This application discloses a main structure for an offshore wind power pile driving guide frame and pile stabilization platform, referring to... Figure 1 The system includes a frame 1 and a detachable working platform 2 connected to the top of the frame 1. The connection between the working platform 2 and the frame 1 can be extended by adding vertical steel pipes to increase the overall height of the main structure of the guide frame stabilizing platform, thereby adapting to changes in water depth in different sea areas and improving the platform's flexibility and applicability.

[0031] Specifically, the overall dimensions of the frame 1 are 22m × 22m × 60m. The frame 1 includes four vertically arranged main leg steel pipes 11 and several connecting steel pipes 12, which connect adjacent main leg steel pipes 11. The main leg steel pipes 11 can be used to insert auxiliary stakes for positioning, ensuring the stability of the platform. In this embodiment, the auxiliary stakes have a diameter of Ф2.3m and a length of approximately 90m. The main leg steel pipes 11 can be made of high-strength steel, such as Q345B type steel, or stainless steel or other corrosion-resistant materials to extend their service life.

[0032] The four main steel pipes 11 of the frame 1 are all fixed with vertical guide cylinder assemblies 3 on their outer sides. The guide cylinder assemblies 3 guide the steel pipe piles so that the steel pipe piles can be accurately and stably inserted into the seabed.

[0033] The working platform 2 includes a rectangular frame 21 and four support steel pipes 22 located at the corners of the rectangular frame 21. Each support steel pipe 22 corresponds to and is connected to the others. The rectangular frame 21 can be made of aluminum alloy or lightweight steel to reduce overall weight and facilitate transportation and installation. The support steel pipes 22 can be made of seamless steel pipes.

[0034] Both the lower end of the outrigger steel pipe 22 and the upper end of the main leg steel pipe 11 are equipped with annular connecting plates, and corresponding detachable fasteners are installed between the annular connecting plates of the outrigger steel pipe 22 and the main leg steel pipe 11. The annular connecting plates can be welded from steel plates with a thickness of approximately 10mm and coated with anti-rust paint. High-strength bolts, such as M20 bolts, can be selected for the detachable fasteners to ensure the stability of the connection.

[0035] The rectangular frame 21 has several horizontal support members 25 inside, which can enhance the rigidity and load-bearing capacity of the rectangular frame 21. The horizontal support members 25 can be square tubes, round tubes or I-beams, and the cross-sectional dimensions are determined according to the stress conditions. The material is the same as that of the rectangular frame 21.

[0036] An extension platform 23 is provided at each corner of the rectangular frame 21, located above the guide tube assembly 3. The extension platform 23 has a clearance space 24 for vertical passage of steel pipe piles. The distal end of the clearance space 24 extends away from the center of the rectangular frame 21 and is open. This allows the steel pipe piles to pass smoothly during construction and accommodates different pile spacing arrangements. The extension platform 23 can be welded from steel plates with a thickness of approximately 10mm, and the edges can be chamfered to reduce the risk of collision.

[0037] The bottom of the frame 1 is equipped with an anti-sinking plate 4, which has several through holes 41. The function of the anti-sinking plate 4 is to prevent the platform from sinking and ensure the stability of the platform on the soft soil layer. The anti-sinking plate 4 can be made of steel plate with a thickness of about 20mm. The diameter of the through holes 41 can be selected according to the size of the silt particles, usually 10cm to 20cm. This ensures both smooth drainage and effective pressure distribution.

[0038] A diagonal bracing pipe is installed between the anti-sinking plate 4 and the main leg steel pipe 11. The diagonal bracing pipe plays a reinforcing role and enhances the structural stability of the entire platform. The diagonal bracing pipe can be made of seamless steel pipe with a diameter of 50mm to 100mm and a wall thickness of 5mm to 8mm. Both ends are fixed to the anti-sinking plate 4 and the main leg steel pipe 11 by welding.

[0039] The implementation principle of this embodiment is as follows:

[0040] The main structure of this offshore wind power pile driving guide frame stabilization platform features a modular design, enabling flexible height adjustment to adapt to varying water depths in different sea areas. Simultaneously, rational material selection and structural design enhance the platform's stability and durability while reducing maintenance costs. Furthermore, the ingenious avoidance design (24) and the application of anti-sinking plates (4) ensure the safety and efficiency of the construction process. This design not only solves the application challenges of existing platforms in complex sea conditions but also improves the overall construction quality and technical level.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
