Under the action of marine hydrodynamics, the seabed around the pile foundation is prone to scouring, forming scour pits, which seriously threaten the safety of the overall structure. Therefore, the protection of offshore wind power foundations is of paramount importance.

[0003] Currently, existing protection methods mostly rely on monitoring technologies and instruments to provide real-time monitoring around the pile foundation structure. However, these traditional methods are difficult to deploy, have high maintenance costs, are easily damaged in extreme sea conditions, and their reliability is difficult to guarantee.

[0004] Therefore, this utility model provides an anti-scouring protection structure for offshore wind power foundations to solve the above problems. Utility Model Content

The snare protection structure includes a floating pipe. After the floating pipe is positioned by a combination of multiple positioning components, a positioning frame is built between the positioning components of the ring. The surface of the frame is connected to a drive motor by bolts.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 An anti-scour protection structure for offshore wind turbine foundations, comprising: The protective ring structure 1 is fitted onto the main body of the wind turbine foundation; The snare protection structure 1 includes a float 11, which is composed of multiple ring tubes. Multiple positioning elements 112, arranged in a ring array along the axis of the float 11, are equidistantly and coplanarly assembled. After assembly, a frame plate 111, providing an assembly platform, is erected on the upper surface of the float 11 between the ring positioning elements 112. A drive motor 122 is bolted to the surface of these frame plates 111, and a reducer or speed increaser is fitted to the shaft of the drive motor 122. The drive motor 122, in conjunction with the reducer or speed increaser, drives the toothed ring 13 located at the center of the float 11 to rotate. Wave aerators are bolted to the surface of the positioning elements 112 on the side closest to the waves. The electrical component 12 and the positioning component 112 are bolted to a generator 121 on the side near the center of the float tube 11. The generator shaft of the generator 121 is connected to the wave discharge component 12 via a transmission component. Thus, the wave discharge component 12 uses the kinetic energy generated by the wave impact to drive the generator 121 to generate electricity. The wave energy generation device includes a wave discharge component 12 (such as a float, oscillating plate, oscillating water column, etc.) that directly interacts with the waves, an intermediate mechanism for energy conversion (such as a hydraulic transmission system, gearbox, linear generator mover, etc.), and a generator 121 (such as a permanent magnet generator, induction generator) that converts mechanical energy into electrical energy. The wave discharge assembly 12 receives the mechanical energy from the up-and-down movement and horizontal impact of the waves, driving the intermediate mechanism to convert the irregular reciprocating motion of the waves into continuous and stable rotational motion (or directly converting the reciprocating motion into electrical energy through a linear generator). The transmission system then transmits this mechanical energy to the generator 121, where it is converted into electrical energy through electromagnetic induction. Finally, the voltage and frequency are adjusted by the control system before being output to the power grid or energy storage equipment, thus completing the wave energy generation process. The entire chain of energy conversion to electricity involves an energy storage device powered by a generator 121 supplying power to a drive motor 122. A drainage impeller 14 is integrally mounted on the lower side of the gear ring 13, extending beyond the float pipe 11. The surface of the drainage impeller 14 has multiple blades that actively push out impact waves, and the blades are inclined to facilitate drainage. This is a mature and well-known prior art. This application does not impose any limitations on the wave discharge component 12, the intermediate mechanism for energy conversion, the generator 121 that converts mechanical energy into electrical energy, the auxiliary structure that ensures stable operation of the device, or the control system that optimizes energy output. Engineers can directly select relevant existing products and technologies based on actual needs and the actual site environment.

[0018] During operation, after the protective structure 1 ring is fitted onto the main body of the wind power foundation, the wave impact positioning component 112 near the wave side of the wave discharge component 12 initially clips the waves. This component transmits the mechanical energy generated by the wave impact to the generator 121 inside the positioning component 112 via the transmission component. The generator 121 converts the mechanical energy into electrical energy through electromagnetic induction and stores it in the matching energy storage device. The energy storage device supplies power to the drive motor 122 on the frame plate 111. The drive motor 122 drives the toothed ring 13 at the center of the floating pipe 11 to rotate via the transmission mechanism. The drainage impeller 14, which is coaxially fixed to the toothed ring 13, rotates synchronously. Its inclined blade actively pushes out the impact waves to weaken the scouring force of the seabed. The entire structure is kept stable by the combination of multiple ring pipes and the positioning components 112 distributed in a ring array, realizing the coordinated operation of anti-scouring protection and wave energy recovery and utilization.

[0019] In summary, through the coordinated arrangement of the wave discharge component 12, generator 121, energy storage device, drive motor 122, and drainage impeller 14, the device can not only convert the mechanical energy generated by wave impact into electrical energy for resource recovery and utilization, but also actively push out impact waves through the drainage impeller 14, thereby weakening the scouring force on the seabed from the source. This breaks through the passive mode of traditional protection that relies solely on monitoring, improving the initiative and environmental friendliness of protection, while reducing dependence on external energy and operating costs. Through the arrangement of the multi-ring pipe combined floating pipe 11, the ring array distributed positioning components 112, and the frame plate 111, the protective structure has a stable overall support performance, providing a reliable assembly platform for functional components such as drive motor 122 and generator 121, and maintaining structural stability in complex marine environments. Furthermore, the bolted connections of each component facilitate disassembly and maintenance, effectively solving the problems of difficult deployment, high maintenance costs, and easy damage under extreme sea conditions in traditional protection methods, ensuring the continuity and reliability of protection.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] Working Principle: During operation, the protective ring structure 1 is first fitted onto the main body of the wind turbine foundation. Waves impact the wave discharge component 12 on the side of the positioning component 112 closest to the wave, thus initially reducing the wave intensity. The wave discharge component 12 transmits the received mechanical energy, such as vertical undulations and horizontal impacts, to the generator 121 on the side of the positioning component 112 closest to the center of the floating tube 11 via a transmission component. The generator 121 converts the mechanical energy into electrical energy through electromagnetic induction. This electrical energy is stored in a matching energy storage device. Subsequently, the energy storage device... The drive motor 122 on the support plate 111 provides power. The drive motor 122, together with the reducer or speed increaser, drives the toothed ring 13 at the center of the floating pipe 11 to rotate. The drainage impeller 14, which is integrally set with the toothed ring 13 and passes over the lower side of the floating pipe 11, rotates synchronously. Its inclined blade actively pushes and pushes the impacting waves, reducing the scouring force of the waves on the seabed around the wind power foundation. At the same time, the entire structure is kept stable by the combination of multiple ring pipes and positioning components 112 distributed in a ring array, realizing the coordinated operation of anti-scouring protection and wave energy recovery.
