[0025] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Depend on Figures 1 to 7The device includes a clamp 1, which comprises a front clamp 2 and a rear clamp 3. Ear plates 4 are hinged to the left sides of the front clamp 2 and the rear clamp 3, and the two ear plates 4 are detachably connected. A locking assembly is provided on the right side of the front clamp 2 and the rear clamp 3, which can quickly fix the front clamp 2 and the rear clamp 3. Multiple L-shaped connecting seats 5 are fixedly connected to the outer wall of the clamp 1, evenly distributed along its circumference. A hanging plate 6 is detachably connected to the upper side of the connecting seat 5. A limiting assembly is provided on the upper side of the connecting seat 5, which can limit the position of the hanging plate 6. A support assembly is provided on the upper side of the connecting seat 5, which is used to support the hanging plate 6. Multiple rubber pads 7 are evenly distributed along its circumference inside the clamp 1.

[0027] like Figures 1 to 7 As shown, the clamp 1 adopts a split design for quick assembly and disassembly, adapting to wind turbine piles of different diameters. The hinged ear plate 4 cooperates with the locking component to form an adjustable ring-shaped fixing structure. Compared with traditional welded or integral structures, the split clamp 1 solves the problem of pile size compatibility, eliminating the need for customized production. The locking component can quickly lock the clamp 1, achieving rapid fixation. The connecting seat 5 serves as the mounting base for the hanging plate 6. The circumferentially distributed design ensures uniform load distribution and avoids local stress concentration. The hanging plate 6 is made of a porous, rough-surfaced material, such as high-strength concrete or specially made corrosion-resistant plastic. Its surface porosity and roughness are conducive to the attachment of marine organisms. A limiting component prevents the hanging plate 6 from shifting under the impact of ocean currents. A support component is provided to share the weight of the hanging plate 6 and the bending moment caused by the increased weight of the organisms. The active load-bearing design extends the service life of the hanging plate 6. A rubber pad 7 increases the friction between the clamp 1 and the wind turbine pile, preventing the clamp 1 from sliding on the pile and protecting the pile surface from wear.

[0028] Two threaded holes are opened on the left and right sides of the outer wall of the ear plate 4. Multiple fixing pins 8 corresponding to the threaded holes are provided on the left side of the clamp 1. The fixing pins 8 are located in the threaded holes on their corresponding sides. The fixing pins 8 are connected to the fixing nuts by threads on the rear side. A washer is provided in front of the ear plate 4 on the front side, between the ear plate 4 and the fixing pins 8.

[0029] like Figures 1 to 3As shown, threaded holes provide installation positions for fixing pins 8. The ear plates 4 are detachably connected via threaded connections, ensuring the stability of the hinged structure on the left side of the front half-hoop 2 and the rear half-hoop 3. The threaded hole design facilitates adjustment and fixing, enabling quick assembly and disassembly of the ear plates 4. It also adapts to wind turbine piles of different diameters. After passing through the threaded holes, the fixing pins 8 engage with the fixing nuts to lock the ear plates 4 on both sides, ensuring the stability of the ring structure of the clamp 1. The threaded connection method is simple and reliable, facilitating on-site operation. The fixing nuts prevent the fixing pins 8 from loosening, enhancing structural stability. A washer is placed between the front ear plate 4 and the fixing pins 8 to distribute the pressure of the fixing pins 8 on the ear plates 4, avoiding localized stress concentration. The ear plates 4 are quickly assembled and disassembled through the threaded holes, fixing pins 8, and nuts. Combined with the hinged design, the clamp 1 can flexibly adapt to wind turbine piles of different diameters, eliminating the need for customized production, reducing costs and installation complexity. The threaded connection between the fixing pins 8 and the nuts provides reliable locking force. The washer protects the ear plates 4 and evenly distributes the load, preventing loosening or localized wear, ensuring the clamp 1 operates stably in the marine environment for a long time.

[0030] The locking assembly includes an L-shaped locking buckle 9, which is fixedly connected to the right side of the front half hoop 2. A base 10 is fixedly connected to the right side of the rear half hoop 3. A swing frame 11 is hinged to the right side of the base 10. A hinge plate 12 is hinged to the middle of the swing frame 11. A threaded rod 13 is threadedly connected to the hinge plate 12. A locking frame 14 is rotatably connected to the front side of the threaded rod 13. A locking rod 15 that can cooperate with the locking buckle 9 is fixedly connected to the locking frame 14. The outer wall of the swing frame 11 is detachably connected to the rear half hoop 3 via a connecting pin 16.

[0031] like Figures 1 to 2 As shown, a locking buckle 9 is fixed to the right side of the front half-clamp 2 as a docking component for the locking rod 15. Through cooperation with the locking rod 15, the front half-clamp 2 and the rear half-clamp 3 are quickly locked, providing a locking fulcrum and ensuring a rigid connection of the locking components, simplifying the operation process. A base 10 is fixed to the right side of the rear half-clamp 3 as a mounting base for the swing frame 11. The swing frame 11, hinge plate 12, threaded rod 13, locking frame 14, and locking rod 15 can be quickly fixed using the swing frame 11 after the locking rod 15 is engaged with the locking buckle 9, directly achieving mechanical locking, preventing the clamp 1 from loosening, and ensuring the stability of the ring structure. At the same time, the extension length of the locking rod 15 can be adjusted using a screw, thus adapting to bases of different diameters. The screw and hinge plate 12 are connected by threads, which has self-locking properties, ensuring that it will not easily loosen. A connecting pin 16 is provided to limit the swing frame 11 after it is fixed, ensuring that it will not loosen.

[0032] The connecting seat 5 has an elongated hole 17 in the middle. A mounting bracket 18 is fixedly connected to one side of the hanging plate 6. The mounting bracket 18 is provided with mounting nails 19, which are located inside the elongated hole 17. A mounting nut is threaded to the other side of the mounting nail 19.

[0033] like Figures 4 to 6 As shown, the sliding fit design of the elongated hole 17 and the mounting nail 19 allows the height of the hanging plate 6 to be flexibly adjusted to adapt to the layout requirements of different biological attachment modules. The mounting frame 18 serves as a transition structure between the hanging plate 6 and the connecting seat 5, transferring the load of the hanging plate 6 to the connecting seat 5 and providing a fixing base for the mounting nail 19. The threaded connection between the mounting nail 19 and the nut provides high-strength locking force to ensure that the hanging plate 6 does not loosen under the impact of ocean currents or biological weight gain. The mounting frame 18 evenly transfers the load to the connecting seat 5 to avoid stress concentration. The length of the connecting seat 5 can be manufactured according to requirements.

[0034] The limiting assembly includes two U-shaped limiting frames 20. One side of the mounting bracket 18 is located inside the limiting frame 20, and the upper and lower sides of the limiting frame 20 are respectively located in the positioning holes 21 on their corresponding sides. The upper and lower sides of the limiting frame 20 are respectively threaded with limiting nuts 22.

[0035] like Figures 4 to 6 As shown, a limiting frame 20 is set up, which covers the side of the mounting frame 18 through the U-shaped structure to limit the vertical displacement of the hanging plate 6, preventing the hanging plate 6 from sliding or shaking due to external forces, and limiting the height of the hanging plate 6. The upper and lower ends of the limiting frame 20 are inserted into the preset positioning holes 21 of the connecting seat 5 to achieve vertical fixation of the limiting frame 20, ensuring that the limiting frame 20 itself does not loosen, and at the same time preventing the mounting frame 18 from moving. The limiting nut 22 is set up to lock the upper and lower ends of the limiting frame 20 through threaded connection to prevent the limiting frame 20 from coming out of the positioning hole 21 and enhance the overall stability.

[0036] The support assembly includes a hinge rod 23, with a connecting rod 24 hinged to the upper side of the hinge rod 23. The upper side of the connecting rod 24 contacts the lower side wall of the hanging plate 6. An end face gear 25 located at the hinge point between the connecting rod 24 and the hinge rod 23 is fixedly connected to the connecting rod 24. A pull rod 26 is slidably connected to the hinge rod 23. A limiting gear 27 that can mesh with the end face gear 25 is fixedly connected to one end of the pull rod 26.

[0037] like Figures 4 to 6 As shown, the hinged design of the hinge rod 23 and the connecting rod 24 allows for flexible adjustment of the support angle. The hinged design adapts to different installation heights of the hanging plate 6, ensuring that the support force is always vertically transmitted to the connecting seat 5, avoiding moment concentration, and providing support for the hanging plate 6. The connecting rod 24 directly contacts the lower side wall of the hanging plate 6, providing rigid support and sharing the load caused by the weight of the hanging plate 6 and the increased weight due to biological attachment. The end face gear 25 is fixed at the hinge of the connecting rod 24 and locks the angle of the connecting rod 24 after meshing with the limit gear 27 to prevent support failure. The pull rod 26 slides to control the meshing and disengagement of the limit gear 27 and the end face gear 25, realizing rapid adjustment and locking of the support angle.

[0038] The pull rod 26 is equipped with a tension spring located between the pull rod 26 and the connecting rod 24.

[0039] like Figure 6 As shown, the tension spring can push the pull rod 26 to the default position to ensure that the limit gear 27 and the end face gear 25 remain engaged in the non-operational state, preventing accidental disengagement. When the support angle needs to be adjusted, the pull rod 26 only needs to be slid against the elastic force of the tension spring. After being released, the tension spring will automatically rebound to re-engage the limit gear 27, simplifying the operation process.

[0040] The lower end of the mounting plate 6 is fixedly connected to buckles 28 located on both sides of the corresponding connecting rod 24. The upper end of the connecting rod 24 is fixedly connected to a pin 29 that can cooperate with the buckle 28 on the corresponding side. A latch 30 is slidably connected to one side of the buckle 28. A push rod 31 is fixedly connected to one end of the latch 30. The push rod 31 is slidably connected to the buckle 28.

[0041] like Figures 4 to 7 As shown, a buckle 28 is fixed to the lower end of the mounting plate 6 and is used to cooperate with the pin 29 at the upper end of the connecting rod 24 to form an auxiliary connection point between the mounting plate 6 and the support assembly. The pin 29 and the buckle 28 cooperate to achieve mechanical engagement and restrict the relative movement between the connecting rod 24 and the mounting plate 6. A latch 30 is set to slide into the engagement gap between the buckle 28 and the pin 29. The push rod 31 is used to control the extension and retraction of the latch 30. In the locked state, the latch 30 is inserted to prevent the pin 29 from coming out, ensuring that the buckle 28 and the pin 29 are firmly engaged. In the unlocked state, pushing the push rod 31 can retract the latch 30, which is convenient for quick disassembly or adjustment of the mounting plate 6. The sliding design of the latch 30 is achieved by one-button operation through the push rod 31, which can complete the fixing or release of the mounting plate 6 without tools, simplifying the maintenance process and adapting to the needs of frequent maintenance or module replacement.

[0042] A return spring is provided on the upper side of the push rod 31, located between the push rod 31 and the hanging plate 6.

[0043] like Figure 7 As shown, a reset spring is provided, which uses its automatic rebound characteristic to ensure that the buckle 28 and the locking pin 29 are always locked, preventing the hanging plate 6 from falling off due to accidental unlocking, which is especially important in harsh marine environments.

[0044] The front half hoop 2 and the rear half hoop 3 are each composed of two fixed hoops 32. The two fixed hoops 32 are hinged in the middle. The rubber pad 7 corresponds to the fixed hoops 32 and is located on the inner wall of the fixed hoops 32. The outer wall of the rubber pad 7 is provided with anti-slip grooves 33.

[0045] like Figures 1 to 3As shown, the clamp 1 is further decomposed into multiple hinged fixing clamps 32 to enhance structural flexibility. Through the central hinge design, the fixing clamps 32 can adapt to local curvature changes in the wind turbine pile foundation, making them particularly suitable for pile foundations with varying diameters or irregular surfaces. Compared to a single arc-shaped structure, the segmented hinge design better conforms to the pile foundation surface, reduces installation gaps, and improves the adaptability and overall stability of the clamp 1. Each fixing clamp 32 is independently equipped with a rubber pad 7 to ensure uniform pressure distribution. The rubber pad 7 acts as a buffer medium, increasing friction and protecting the pile foundation surface. The anti-slip groove 33 allows for directional drainage, reducing the risk of corrosion caused by seawater retention. Simultaneously, the groove structure effectively disperses tangential forces, enhancing anti-slip capability.

[0046] When using this invention, the front half hoop 2 and the rear half hoop 3 are hinged together by the ear plate 4 and temporarily fixed with the fixing nail 8, washer and fixing nut to keep the hoop 1 in an adjustable state. Check the mobility of the threaded rod 13, locking frame 14 and swing frame 11 of the locking assembly to ensure that the locking rod 15 can be smoothly inserted into the locking buckle 9. Measure the diameter of the target installation section of the wind power pile foundation. Select the material of the hanging plate 6 according to the marine organism attachment requirements and pre-install the buckle 28 and the pin 29 assembly. Check the elastic performance of the return spring and tension spring.

[0047] Wrap the clamp 1 around the wind turbine pile foundation, tighten the fixing nut at the ear plate 4 according to the diameter of the wind turbine pile foundation to ensure the hinge point is stable, close the front half clamp 2 and the rear half clamp 3, rotate the threaded rod 13 to adjust the position of the locking rod 15 to ensure that the clamp 1 can be locked properly, then insert the locking rod 15 into the locking buckle 9 through the swing frame 11, rotate the swing frame 11 in the direction to ensure that the clamp 1 is completely locked, and use the connecting nail 16 to fix the swing frame 11 and the rear half clamp 3 to prevent the impact of ocean currents from causing loosening;

[0048] The mounting pins 19 of the sliding mounting plate 6 are adjusted in height within the elongated hole 17. After positioning, the mounting nut is tightened. The limiting bracket 20 is inserted into the positioning hole 21 of the connecting seat 5 and locked with the limiting nut 22 to limit the vertical displacement of the mounting plate 6. The pull rod 26 is pulled to disengage the limiting gear 27 from the end face gear 25. Then, the hinge rod 23 and connecting rod 24 of the support assembly are unfolded so that the top of the connecting rod 24 is attached to the lower surface of the mounting plate 6. The pull rod 26 is released, and the pull rod 26, under the action of the tension spring, engages the limiting gear 27 with the end face gear 25, automatically locking the support angle. During this period, the push rod 31 of the latch 30 is pressed to insert the latch 29 of the connecting rod 24 into the latch 28 of the mounting plate 6. After the push rod 31 is released, the return spring pushes the latch 30 to lock the latch 29.

[0049] Monitor the biological attachment status of the hanging plate 6 quarterly to assess the ecological restoration effect, remove excessive attachments to avoid overloading, and if the clamp 1 becomes loose, retighten the threaded rod 13 or replace the connecting nail 16. There is no need to remove the entire hanging plate. When adding a new hanging plate 6, simply repeat the installation process.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
