Description

Technical Field

[0001] The present application belongs to the technical field of wave-breaking devices, and more specifically, relates to a flexible wave-breaking device for a floating wind turbine. Background Art

[0002] As offshore wind power projects continue to expand to deeper and more complex seas, floating wind power platforms must be able to withstand complex and often extremely harsh sea conditions to ensure continuous and stable operation. In this context, wave-breaking devices are particularly important. Their core purpose is to weaken the energy of waves, thereby reducing the platform's motion responses such as pitch and heave caused by the action of waves.

[0003] Traditionally, wave-breaking designs rely on rigid structures, such as fixed wave-breaking panels or sturdy column shells. These designs can indeed absorb and disperse some wave energy to a certain extent, thereby reducing the direct impact on the platform. However, in practical applications, especially in the face of marine environments where wave frequency and direction frequently change, the limitations of these rigid structures gradually become apparent. They are often prone to excessive reflection of waves, which not only fails to fully dissipate wave energy, but may also aggravate the dynamic response of the platform. What's more serious is that in extreme sea conditions, rigid wave-breaking structures may be damaged due to the inability to withstand the huge wave impact force, causing serious threats to the stability and safety of the entire platform. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a flexible wave-breaking device for a floating wind turbine, so as to solve the technical problem of poor wave-breaking effect existing in the prior art.

[0041] To improve the wave-breaking effect of the wave-breaking device. Figure 1 and Figure 2 As shown, the present application provides a flexible wave-breaking device for a floating wind turbine, comprising a wave-breaking plate 2 and a flexible connection assembly.

[0042] Among them, the wave-breaking plates 2 are spaced apart from the surface of the installation base 1, allowing the wave-breaking plates 2 to move within a certain range. There are multiple wave-breaking plates 2, and each wave-breaking plate 2 is arranged at intervals from each other along the height direction and the peripheral direction of the installation base 1, thereby forming a multi-level protection system in space. In the height direction of the installation base 1, the wave-breaking plates 2 are arranged in multiple rows in sequence. Such a layout not only adapts to the changes in different water levels and wave heights, but also ensures that at least part of the wave-breaking plates are located below the waterline, at the waterline position, and above the waterline, respectively, providing the necessary redundancy for the wave-breaking effect, ensuring that excellent wave-breaking effects can be achieved in various extreme sea conditions. Setting up multiple rows of wave-breaking plates 2 can gradually reduce the energy of the waves in the process of contacting these wave-breaking plates 2 layer by layer, thereby reducing the direct impact of the waves on the installation base 1. Multiple wave-breaking plates 2 are arranged in the peripheral direction of the installation base 1 to cope with the impact of waves coming from all directions on the installation base 1.

[0043] One end of the flexible connection component is connected to the wave-breaking board 2, and the other end is connected to the installation base 1 in a detachable manner, which not only simplifies the installation and disassembly process of the device, but also reduces the complexity of the overall construction and subsequent maintenance costs. When the wave-breaking board 2 is impacted by waves, the flexible connection component gives the wave-breaking board 2 the ability to respond dynamically when facing the impact of waves. The flexible connection component can use its flexible deformation characteristics to effectively absorb and dissipate the kinetic energy of the waves, while reducing the reflection of the waves, thereby improving the wave-breaking effect and extending the service life of the installation base.

[0044] like Figure 3 and Figure 4 As shown, in a specific embodiment of the present application, the flexible connection assembly includes a flexible member and a fastener 4. One end of the flexible member is connected to the wave-breaking board 2, and the other end is connected to the mounting base 1. When waves hit the wave-breaking board 2, the flexible member can utilize its elastic bending properties to effectively absorb and dissipate the kinetic energy of the waves, while reducing the reflection of the waves. The fastener 4 is used to fasten the end of the flexible member to the wave-breaking board 2 or the mounting base 1. The fastener 4 can not only effectively resist the dynamic load from the waves, but also maintain the tightness of the connection during long-term use to prevent performance degradation due to loosening or fatigue. The specific implementation form of the fastener 4 includes but is not limited to fastening devices such as bolts and screws.

[0045] like Figure 1 and Figure 2As shown, in a specific embodiment of the present application, there are multiple flexible parts, and the flexible parts are arranged at intervals from each other to form multiple points of support for the wave-breaking board 2, ensuring that the wave-breaking board 2 can effectively disperse the external force to each supporting point when facing wave impact, and also reducing the risk of single-point overload, thereby enhancing the adaptability of the wave-breaking board 2 to dynamic loads, extending the service life of a single flexible part, and making it exhibit better durability in a complex and changeable marine environment.

[0046] like Figures 1 to 4 As shown, in a specific embodiment of the present application, the flexible member can be specifically a spring 3. As a commonly used mechanical element, the spring 3 has the advantages of high elasticity and low manufacturing cost. The spring 3 is made of stainless steel or corrosion-resistant alloy steel to ensure long-term durability in the marine environment. Both ends of the spring 3 are fixed inside the connecting flange 5, which increases the contact area between the end of the spring 3 and the wave-breaking plate 2 or the mounting base 1, thereby improving the stability of the connection, and also effectively disperses the local stress generated by the spring 3 on the wave-breaking plate 2 or the mounting base 1 when the force is applied through the expansion area of ​​the connecting flange 5. The fastener 4 is used to fasten the connecting flange 5 to the wave-breaking plate 2 or the mounting base 1.

[0047] like Figures 5 to 8 As shown, in a specific embodiment of the present application, the flexible member can also be an elastic column 6 made of rubber or other high molecular elastic materials, which not only gives the elastic column 6 good elasticity, but also enables it to effectively cope with the rust of seawater. Both ends of the elastic column 6 are provided with flanges extending outward in the radial direction, which are also used to increase the installation fitting area between its end and the wave-breaking plate 2 or the installation base 1 to improve the stability of the connection. A connecting flange 5 is provided on the flange, and the fastener 4 passes through the connecting flange 5 and the flange in sequence to fasten the end of the elastic column 6 to the wave-breaking plate 2 or the installation base 1.

[0048] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present application, the wave-breaking plate 2 is specifically a curved plate. The convex surface of the curved plate faces the outside of the mounting base 1. Due to the guiding effect of the convex surface of the curved plate, the waves will be deflected after contacting the convex surface, reducing the possibility of direct reflection back to the ocean surface, thereby avoiding the formation of superimposed reflected waves that may aggravate the impact of the waves. The flexible connection component is connected to the concave surface of the curved plate.

[0049] like Figure 1 and Figure 2As shown, in a specific embodiment of the present application, the projection shape of the curved plate on the horizontal plane and the projection shape of the vertical plane are both curved. When the wave contacts the curved plate, the impact direction will change due to the smooth transition of its surface, thereby avoiding the local stress concentration caused by direct impact and reducing the risk of structural damage, so that the wave-breaking board can maintain higher structural integrity and stability when facing the continuous impact of waves.

[0050] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present application, a plurality of wave-breaking holes are provided on the wave-breaking plate 2 and are spaced apart from each other. The diameter of the wave-breaking holes ranges from 5 cm to 15 cm. The wave-breaking holes can be through holes in circular, streamlined, elliptical and other shapes. When the waves pass through these wave-breaking holes, they can be subjected to a more uniform distribution of resistance, thereby avoiding the formation of local stress concentration and eddy currents, and also enabling the waves to be effectively decomposed when passing through the wave-breaking holes, and consuming a large amount of energy in the process, thereby reducing the impact of the waves on the installation base 1.

[0051] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present application, the wave-breaking board 2 is arranged at an angle relative to the horizontal plane, and the angle ranges from 30° to 40°. Through experiments and data analysis, when the angle of the wave-breaking board 2 is within this range, it can effectively guide the waves to flow downward or sideways, avoid the waves from directly hitting the surface of the installation base 1, and reduce the energy of the vertical impact.

[0052] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
