Description
Technical Field
[0001] This application relates to the field of offshore wind power construction equipment, and in particular to an anti-sinking plate structure for an offshore wind power pile driving guide frame stabilization platform. Background Technology
[0002] Offshore wind power, as an important renewable energy source, has been widely applied and developed globally. With advancements in marine engineering technology and equipment, the scale of offshore wind power facilities construction continues to expand, placing increasingly higher demands on construction equipment and technology. Among these, pile driving is a crucial step in the installation of offshore wind turbine foundations, and its stability directly affects the smooth progress of the entire project and its long-term operational safety.
[0003] To ensure stability and accuracy during pile driving, existing technical solutions primarily focus on optimizing the design of the guide frame. Common methods include using rigid support structures, adding auxiliary positioning devices, and improving the power system of the pile hammer. These measures can improve pile driving accuracy and reduce the risk of deviation to some extent. In addition, some anti-sinking slab designs employ a single, large-sized structure to enhance stability by increasing the contact area. However, such a single, large-sized anti-sinking slab is difficult to install on-site, requiring complex hoisting equipment, and the assembly quality with the guide frame is difficult to guarantee; therefore, there is still room for improvement. Summary of the Invention
[0004] To facilitate on-site installation and improve installation quality, this application provides an anti-sinking plate structure for an offshore wind power pile driving guide frame stabilization platform.
[0005] The anti-sinking plate structure of the offshore wind power pile driving guide frame stabilization platform provided in this application adopts the following technical solution:
[0006] An anti-sinking plate structure for an offshore wind power pile driving guide frame stabilization platform includes a guide frame body and several plate units disposed at the bottom of the guide frame body. The plate units are spliced end to end to form the anti-sinking plate body and form a through groove in the middle of the anti-sinking plate body. Semi-circular grooves are reserved at the splicing surfaces between adjacent plate units located at the corners of the anti-sinking plate body. The semi-circular grooves of adjacent plate units are spliced together to form the insertion position at the lower end of the main leg of the guide frame body.
[0007] By adopting the above technical solution, the anti-sinking plate body formed by splicing several plate units end to end can provide a stable support structure at the bottom of the guide frame body. At the same time, the through groove formed in the middle of the anti-sinking plate body facilitates the installation of the main legs of the guide frame body. The semi-circular groove design between adjacent plate units located at the corners of the anti-sinking plate body allows adjacent plate units to form a precise insertion position after splicing, ensuring that the lower end of the main legs of the guide frame body is firmly inserted, thereby improving the stability and assembly accuracy of the entire structure.
[0008] Preferably, a diagonal bracing member is provided between the surface of the plate unit and the main leg of the guide frame body.
[0009] By adopting the above technical solutions, the diagonal bracing components can effectively enhance the connection strength and stability between the plate unit and the main legs of the guide frame, preventing structural deformation or damage caused by external environmental factors during construction. Simultaneously, the diagonal bracing components can also improve the overall rigidity of the entire anti-sinking plate structure, ensuring accurate positioning and stable support during pile driving operations.
[0010] Preferably, the plate unit is provided with a plurality of through holes, which are distributed around the periphery of the through groove.
[0011] By adopting the above technical solution, the main body of the anti-sinking slab is composed of several plate units spliced together. The layout can be flexibly adjusted according to actual needs, allowing the guide frame to better distribute pressure and reduce sinking problems caused by excessive local stress. The through-channel formed in the center helps reduce the overall weight of the anti-sinking slab while maintaining structural strength, thereby improving the platform's stability and load-bearing capacity. The surrounding through-holes can reduce the bottom-holding force and decrease the mud-penetration depth on soft muddy seabeds; and increase the bottom-holding force and improve bottom stability under sandy and gravelly geological conditions. This design not only improves construction efficiency but also reduces maintenance costs.
[0012] Preferably, a plurality of reinforcing ribs are provided below the plate unit, and the plurality of reinforcing ribs are welded and fixed to the outer periphery of the bottom of the main leg of the guide frame body.
[0013] By adopting the above technical solution, the reinforcing ribs installed below the plate unit can significantly improve the overall rigidity and stability of the anti-sinking plate, effectively preventing deformation and damage caused by impact forces in the marine environment. At the same time, these reinforcing ribs are welded and fixed to the outer periphery of the bottom of the main legs of the guide frame body, further enhancing the structural integrity and ensuring that the anti-sinking plate maintains good load-bearing capacity and corrosion resistance during long-term use.
[0014] Preferably, the through groove outline is square, and the extension direction of the splicing surface between adjacent plate units at the outer corner of the through groove is consistent with the extension direction of the diagonal of the through groove outline.
[0015] By adopting the above technical solutions, the square design of the channel outline ensures that the main body of the anti-sinking plate has good symmetry and stability, facilitating the precise positioning of the guide frame during offshore wind power pile driving. Simultaneously, setting the splicing surface between adjacent plate units at the outer corners of the channel to extend along the diagonal of the channel outline effectively improves the connection strength between plate units, preventing structural deformation caused by uneven stress, thereby enhancing the durability and reliability of the entire anti-sinking plate structure.
[0016] Preferably, the surface of the anti-sinking plate body is provided with a plurality of underwater ballast devices for detecting and adjusting the underwater attitude of the anti-sinking plate body. The plurality of underwater ballast devices are distributed around the periphery of the channel. The plurality of underwater ballast devices adjust the horizontal attitude of the anti-sinking plate body during the sinking process by adjusting the weight load at different positions of the anti-sinking plate body.
[0017] By adopting the above-mentioned technical solution, the underwater attitude of the anti-sinking slab can be effectively monitored and adjusted, ensuring that it remains horizontal during the sinking process. Specifically, multiple underwater ballast devices are distributed around the channel, and the attitude of the anti-sinking slab can be precisely controlled by adjusting the weight load at different locations, thereby avoiding installation deviations caused by incorrect attitude and improving construction accuracy and safety.
[0018] Preferably, the underwater ballast device includes a ballast tank, a water pump connected to the ballast tank, and a water pipe connected to the water pump. The water pump draws seawater into or out of the ballast tank through the water pipe to achieve the filling and discharging of the ballast tank.
[0019] By adopting the above technical solution, the anti-sinking slab structure can achieve precise attitude control of the slab body using ballast water tanks, pumps, and pipes. Specifically, by using the pumps to pump seawater into or out of the ballast water tanks, the weight distribution in different areas of the anti-sinking slab body can be flexibly adjusted, thereby effectively correcting any attitude deviations that may occur when the slab body sinks in the water. This design significantly improves the stability and accuracy of the anti-sinking slab body installation process, ensuring the quality and efficiency of subsequent construction.
[0020] Preferably, the underwater ballast device further includes a depth sensor for detecting the submersion depth of the anti-sinking plate body, an inclination sensor for detecting the tilt angle of the anti-sinking plate body, and a pressure sensor for detecting the pressure inside the ballast water tank.
[0021] By adopting the above technical solutions, the water depth, tilt angle, and pressure in the ballast water tank of the anti-sinking slab can be monitored in real time, ensuring the stability and balance of the anti-sinking slab during descent and effectively preventing installation failure or damage due to unstable posture. Simultaneously, the data from these sensors provides operators with precise information, facilitating timely adjustments to the ballast device's operating status and improving construction efficiency and safety.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The anti-sinking plate body is formed by splicing several plate units end to end, and semi-circular grooves are reserved at the corners to form insertion positions, which can effectively simplify the on-site installation process, while ensuring good cooperation with the main legs of the guide frame body, significantly improving the assembly efficiency and reliability of the structure.
[0024] 2. The main body of the anti-sinking plate forms a through groove in the middle, and the splicing surface of the outer corner of the through groove extends in the same direction as the diagonal of the outline. This design not only optimizes the stress distribution, but also improves the stability of the overall structure and adapts to the pile driving requirements under complex sea conditions.
[0025] 3. An underwater ballast device is installed on the surface of the plate unit. The underwater attitude of the anti-sinking plate body can be precisely controlled by adjusting the weight load at different positions, which further ensures the level of the platform during the pile driving process, reduces the risk of displacement and improves construction accuracy.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses an anti-sinking plate structure for a offshore wind power pile driving guide frame stabilization platform, referring to... Figure 1 The system includes a guide frame body 1 and several plate units 21 disposed at its bottom. The plate units 21 are spliced end-to-end to form an anti-sinking plate body 2, creating a through groove 23 in the middle of the anti-sinking plate body 2. Semi-circular grooves 24 are pre-reserved at the splicing surfaces between adjacent plate units 21 located at the corners of the anti-sinking plate body 2. The semi-circular grooves 24 on two adjacent plate units 21 can be spliced to form an insertion position for the main legs of the guide frame body 1 to be inserted. This design ensures a good connection between the anti-sinking plate and the guide frame body 1 while facilitating rapid on-site assembly. The main legs of the guide frame body 1 are welded and fixed to the anti-sinking plate body 2.
[0032] Specifically, the plate units 21 are connected by bolts or other fasteners; for example, a flange structure with locating pins can be used to achieve precise mating. Furthermore, to enhance connection reliability, welding can be used for further fixation. Each plate unit 21 has multiple sets of through holes 22 distributed around the periphery of the through groove 23.
[0033] The central channel 23 helps reduce the overall weight of the anti-sinking slab while maintaining structural strength, thereby improving the platform's stability and load-bearing capacity. The surrounding through-holes 22 reduce the bottom-holding force and decrease the immersion depth on soft muddy seabeds; and increase the bottom-holding force and improve bottom stability under sandy and gravelly geological conditions. This design not only improves construction efficiency but also reduces maintenance costs.
[0034] To improve the overall rigidity of the anti-sinking plate, multiple reinforcing ribs are provided below the plate unit 21. These reinforcing ribs are firmly fixed to the outer periphery of the bottom of the main leg of the guide frame body 1 by welding or other methods. The cross-sectional shape of the reinforcing ribs can be I-shaped, box-shaped, or other forms suitable for bearing loads. At the same time, diagonal bracing members 25 are also provided on the surface of the plate unit 21 near the main leg of the guide frame body 1. The diagonal bracing members 25 are made of diagonal steel pipes, which provide lateral tensile reinforcement and effectively prevent swaying caused by wave impact.
[0035] In this embodiment, the through groove 23 has a square outline, which ensures that the anti-sinking plate body 2 has good symmetry and stability. In addition, the extension direction of the splicing surface between adjacent plate units 21 at the outer corner of the through groove 23 is consistent with the extension direction of the diagonal of the through groove 23 outline, which can effectively improve the connection strength between plate units 21, avoid structural deformation caused by uneven stress, and thus improve the durability and reliability of the entire anti-sinking plate structure.
[0036] Reference Figure 2 and Figure 3To precisely control the underwater attitude of the anti-sinking plate, several underwater ballast devices 3 are installed on the surface of the anti-sinking plate body 2. Each underwater ballast device 3 includes a ballast water tank 31, a water pump 32 connected to the ballast water tank 31, a water pipe 33 connected to the water pump 32, and valves installed on the water pipe 33. The ballast water tank 31 is a container for storing ballast water. Depending on the different requirements and design of the device, multiple ballast water tanks 31 of different positions and sizes are installed on the anti-sinking plate body 2. The water pump 32 is used to pump seawater into or out of the ballast water tank 31, realizing the filling and discharging of ballast water. The water pipe 33 and valves are responsible for connecting the various components and controlling the flow path and flow rate of the ballast water. The water pipe 33 includes a ballast pipe 331 for water intake and a discharge pipe 332 for water discharge. During operation, the water pump 32 pumps seawater into or out of the ballast water tank 31 through the water pipe 33, thereby achieving the purpose of filling and discharging. A filter 34 is installed between the water pump 32 and the ballast water tank 31 to improve the problem of inaccurate ballast control caused by sand and gravel impurities entering the ballast water tank 31. In addition, the underwater ballast device 3 also includes a depth sensor, a tilt sensor, and other necessary detection elements to monitor the status changes of the anti-sinking plate in real time.
[0037] In this embodiment, a depth sensor measures the depth of the anti-sinking plate body 2, a tilt sensor detects the tilt angle of the anti-sinking plate body 2, and a pressure sensor monitors the pressure inside the ballast water tank 31. This data is transmitted to the controller, which analyzes and processes it using algorithms and models. When the controller determines that the device's attitude has tilted based on the sensor data, it calculates which ballast water tanks 31 need to be injected into or how much ballast water needs to be discharged to restore the device's balance, and then issues corresponding commands to control the actions of the ballast pumps and valves. A communication module is added between the various components and the controller, allowing operators to communicate remotely with the device via a computer or other terminal devices, monitor the device's operating status in real time, and send control commands according to actual conditions, thus achieving remote intelligent control of the device.
[0038] The implementation principle of the anti-sinking plate structure of the offshore wind power pile driving guide frame stabilization platform in this application embodiment is as follows: by decomposing and reconstructing the traditional large integrated anti-sinking plate, a miniaturized split plate group mode that is easy to transport and deploy is adopted. This improvement not only solves the problem of inconvenient handling of whole pieces in the past, but also makes full use of the cost advantages of standardized production.
[0039] The ballast water treatment system operates automatically, using sensors and a control system to monitor the load on the guide frame body 1 and changes in sea state in real time, thus achieving intelligent control of the ballast water treatment system. Once the system detects that the platform needs to adjust its buoyancy and stability, it automatically activates the corresponding pumps and valves to inject or discharge an appropriate amount of water to meet overall stability requirements. By controlling the amount of water in the compartments, the ballast water treatment system adjusts the platform's buoyancy and stability to adapt to different operational and sea state requirements.
[0040] The underwater ballast device 3 adjusts its buoyancy in the water by injecting or discharging ballast water into the ballast tank 31, thereby changing the device's own weight. When sinking is required, the ballast pump draws seawater into the ballast tank 31, increasing the device's weight so that gravity exceeds buoyancy, and the device begins to sink. When surfacing or adjusting its attitude is required, the ballast pump discharges water from the ballast tank 31, reducing the device's weight so that buoyancy exceeds gravity, and the device will surface or reach the desired attitude.
[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.
