Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power engineering, and in particular to a recoverable anti-scour device for an offshore wind power foundation and an operating method thereof. Background Art

[0002] With technological advancements and the pressure of climate change, offshore wind power generation has become an important alternative to fossil fuels. Offshore wind power not only provides renewable, clean energy and reduces carbon emissions, but can also be built away from densely populated areas, minimizing the impact on residents' lives.

[0003] Suction tube foundations, a type of offshore wind farm foundation, are widely used due to their advantages, such as quick installation and minimal environmental disturbance. However, in actual use, due to natural factors such as ocean currents, the sand surrounding the suction tube foundation is easily washed away, resulting in the formation of pits around the suction tube foundation. This reduces the buried depth of the suction tube foundation, severely reducing the suction tube foundation's anti-overturning ability. This problem significantly affects the stability and safety of the suction tube foundation.

[0004] Currently, common measures to address scour include laying anti-scour stones, concrete bags, or other materials around the suction cylinder foundation to reduce sand loss. However, these methods have limited effectiveness, are short-lived, and fail to completely resolve the potholes caused by scour. Furthermore, traditional anti-scour measures are non-recyclable and costly, leading to material waste and secondary damage to the marine environment. Summary of the Invention

The support main body 200 is connected to the suction cylinder base 100 through the connecting assembly 310. The first support assembly 210 and the second support assembly 220 are detachably connected through the locking assembly 320. The clamping assembly 330 clamps the support member 400, and the length direction of the support member 400 extends in a direction away from the suction cylinder base 100; the anti-scouring cloth 500 is fixedly connected to the support member 400, and the anti-scouring cloth 500 is arranged around the suction cylinder base 100.

[0049] In this embodiment, the support body 200 is mounted on the suction cylinder foundation 100 by means of a first support assembly 210 and a second support assembly 220, and the first support assembly 210 and the second support assembly 220 are detachably connected by means of a locking assembly 320, so as to realize a detachable connection between the support body 200 and the suction cylinder foundation 100, thereby facilitating installation and disassembly, and enabling recycling, reducing resource waste, and also avoiding damage to the marine environment. Furthermore, the locking mechanism 300 also includes a clamping assembly 330, on which a support member 400 is provided for fixing and connecting the anti-scouring cloth 500. By arranging the anti-scouring cloth 500 around the suction cylinder foundation 100 and fixing and supporting it by means of the support member 400, the loss of sand can be effectively prevented, thereby effectively improving the stability and anti-overturning capability of the suction cylinder foundation 100, and thereby improving the overall operational safety and service life of the suction cylinder foundation 100.

[0050] In one embodiment, the first support assembly 210 includes a hinge portion 211 and a connecting portion 212. A plurality of support units 213 are connected between the hinge portion 211 and the connecting portion 212. The support units 213 and the hinge portion 211, the support units 213 and the connecting portion 212, and the connection between two adjacent support units 213 are connected at an angle. The second support assembly 220 has the same structure as the first support assembly 210. The hinge portions 211 of the first support assembly 210 and the second support assembly 220 are hingedly connected to each other, and the connecting portions 212 of the first support assembly 210 and the second support assembly 220 are detachably connected via a locking assembly 320. Specifically, the hinge portions 211 of the first support assembly 210 and the second support assembly 220 are hingedly connected via a hinge 230, resulting in a simple and reliable structure.

[0051] In one embodiment, the support unit 213 includes a support frame 2131, the support frame 2131 includes two vertical beams 2132 arranged opposite to each other, the connecting component 310 is arranged on the support frame 2131, the connecting component 310 includes a bidirectional screw 311, the two ends of the bidirectional screw 311 are respectively connected to the two vertical beams 2132, and the threaded sections arranged oppositely on both sides of the bidirectional screw 311 are respectively connected to the first moving member 312 and the second moving member 313. The rotation of the bidirectional screw 311 drives the first moving member 312 and the second moving member 313 to move relatively closer or farther away. A first positioning rod 314 is hinged on the first movable member 312, and a second positioning rod 315 is hinged on the second movable member 313. The end of the first positioning rod 314 away from the first movable member 312 and the end of the second positioning rod 315 away from the second movable member 313 are hinged to form an abutment portion 317. When the first movable member 312 and the second movable member 313 move relatively close to each other, the first positioning rod 314 and the second positioning rod 315 rotate relatively close to each other so that the abutment portion 317 abuts against the suction cylinder base 100, thereby realizing the connection and fixation of the support body 200 and the suction cylinder base 100.

[0052] In one embodiment, the connecting assembly 310 further includes a screw motor (not shown), which is in transmission connection with the bidirectional screw 311 to drive the bidirectional screw 311 to rotate. Specifically, in this embodiment, the screw motor is embedded in the vertical beam 2132 and is in transmission connection with the bidirectional screw 311 via a coupling.

[0053] In one embodiment, the connecting assembly 310 further includes a guide rod 316, the two ends of which are respectively connected to the two vertical beams 2132, and the first moving member 312 and the second moving member 313 are respectively provided with a guide hole (not shown) for the guide rod 316 to pass through, so that the movement of the first moving member 312 and the second moving member 313 is smoother. Further, two guide rods 316 are provided, which are respectively arranged on both sides of the bidirectional screw 311 to ensure the stability of the movement of the first moving member 312 and the second moving member 313, and to ensure the motion stability of the first positioning rod 314 and the second positioning rod 315.

[0054] In one embodiment, the suction cylinder base 100 is provided with a slot 110 for the abutting portion 317 to be inserted into, so as to improve the stability of the connection between the support body 200 and the suction cylinder base 100 .

[0055] In one embodiment, the locking assembly 320 includes a first shell 321 and a second shell 322, and the first shell 321 and the second shell 322 are respectively arranged on the connecting parts 212 of the first support assembly 210 and the second support assembly 220. A driving cavity 323 is provided in the first shell 321, and a driving motor 324 is slidingly provided in the driving cavity 323. The output end of the driving motor 324 is transmission-connected with a recovery screw 325. A first threaded hole 326 is provided on the side of the first shell 321 facing the second shell 322, and a second threaded hole 327 is provided in the second shell 322. The recovery screw 325 is threadedly connected to the first threaded hole 326 and the second threaded hole 327, respectively.

[0056] In one embodiment, the locking mechanism 300 further includes a separation assembly 340, which includes a first sleeve 342 disposed on the first housing 321 and a second sleeve 341 disposed on the second housing 322. A compression spring 343 is disposed between the first sleeve 342 and the second sleeve 341. The first sleeve 342 and the second sleeve 341 are connected by a snap-fit ​​structure 344. When the first sleeve 342 and the second sleeve 341 are connected, the compression spring 343 is in a compressed state, i.e., the compression spring 343 can always keep the first sleeve 342 and the second sleeve 341 moving away from each other. Therefore, after the snap-fit ​​structure 344 is released, the first sleeve 342 and the second sleeve 341 are forced apart by the compression spring 343, and the first housing 321 and the second housing 322 are forced apart. This allows the first support assembly 210 and the second support assembly 220 to quickly separate during disassembly, facilitating recovery operations.

[0057] In one embodiment, the clamping assembly 330 includes a plurality of clamping shells 331 fixedly connected to the support body 200. The plurality of clamping shells 331 are distributed around the support body 200 so that the support members 400 clamped to the clamping shells 331 are distributed around the outside of the support body 200, i.e., outside the suction cylinder base 100, ensuring that a sufficient number of support members 400 are provided to compress and secure the anti-scour cloth 500. A first clamping member 332 and a second clamping member 333 are slidably mounted on the clamping shells 331. The clamping shells 331 are provided with a first slide 338 for sliding the first clamping member 332 and a second slide 339 for sliding the second clamping member 333. The first clamping member 332 is provided with a first clamping groove 334, and the second clamping member 333 is provided with a second clamping groove 335. The shapes of the first clamping groove 334 and the second clamping groove 335 are adapted to the outer shape of the support member 400 to secure the support member 400. In actual operation, the support member 400 adopts a weight-bearing square rod, which is convenient for clamping, simple in material acquisition, low in cost, and can achieve compression and fixation of the anti-scour cloth 500.

[0058] Furthermore, the clamping housing 331 is provided with a clamping motor 336. A clamping gear 337 is provided at the output end of the clamping motor 336. The clamping gear 337 is in transmission connection with the first clamping member 332 and the second clamping member 333, respectively, to drive the first clamping member 332 and the second clamping member 333 to move toward or away from each other, thereby clamping and releasing the support member 400. Racks (not shown) are provided on the first clamping member 332 and the second clamping member 333, respectively, to mesh with the clamping gear 337.

[0059] like Figures 1 to 10 As shown, on the other hand, a method for operating a recoverable anti-scour device for an offshore wind power foundation is provided, and the method includes the following steps:

[0060] One end of the first support assembly 210 and one end of the second support assembly 220 are hingedly connected to form the support body 200. The locking assembly 320, the connecting assembly 310, and the clamping assembly 330 of the locking mechanism 300 are respectively installed on the support body 200. Specifically, the first shell 321 and the second shell 322 of the locking assembly 320 are respectively installed on the connecting parts of the first support assembly 210 and the second support assembly 220.

[0061] The supporting body 200 equipped with the locking mechanism 300 is placed outside the suction cylinder base 100 by a power device;

[0062] The other end of the first support assembly 210 and the other end of the second support assembly 220 are connected and fixed by the locking assembly 320, that is, the connecting parts of the first support assembly 210 and the second support assembly 220 are connected and fixed to each other; specifically, the drive motor 324 is started to drive the recovery screw 325 to rotate, and the recovery screw 325 rotates in the first threaded hole 326 and moves toward the second threaded hole 327 of the second shell 322. At this time, the recovery screw 325 drives the drive motor 324 to move along one side of the second shell 322 in the drive cavity 323. Until the recovery screw 325 enters the second threaded hole 327 and completes the threaded connection with the second threaded hole 327, the recovery screw 325 connects and fixes the first shell 321 and the second shell 322, thereby realizing the connection and fixation of the first support assembly 210 and the second support assembly 220;

[0063] The support body 200 is connected and fixed to the suction cylinder foundation 100 through the connecting assembly 310; specifically, the screw motor is started to drive the bidirectional screw 311 to rotate, so that the first moving member 312 and the second moving member 313 move relatively close to each other, thereby driving the first positioning rod 314 and the second positioning rod 315 to rotate relatively close to each other, so that the abutting portion 317 extends toward one side of the suction cylinder foundation 100 and abuts against the outer side surface of the suction cylinder foundation 100, so as to clamp the support body 200 on the suction cylinder foundation 100, thereby achieving the connection and fixation of the support body 200 and the suction cylinder foundation;

[0064] The support member 400 is clamped by the clamping assembly 330. Specifically, the clamping motor 336 is started to drive the clamping gear 337 to rotate, and the clamping gear 337 drives the first clamping member 332 and the second clamping member 333 to move relatively close to each other, and the support member 400 is clamped and fixed from both sides of the support member 400 through the first clamping groove 334 and the second clamping groove 335.

[0065] The anti-scour cloth 500 is installed around the outside of the suction cylinder base 100, and the anti-scour cloth 500 is connected and fixed to the support member 400 so that the anti-scour cloth 500 remains horizontally laid;

[0066] The suction cylinder foundation 100 with the supporting body 200 installed is transported to a designated location on the seabed by a power device;

[0067] The clamping assembly 330 is operated to release the support member 400. Under the action of gravity, the support member 400 drives the anti-scour cloth 500 to cover the seabed outside the suction cylinder foundation 100, forming an anti-scour assembly.

[0068] The locking assembly 320 is operated to disconnect the first support assembly 210 from the second support assembly 220, and the first support assembly 210 and the second support assembly 220 are opened along both sides of the suction cylinder base 100. At the same time, the support body 200 is released from the suction cylinder base 100, and then the support body 200 is recovered by a power device or manually dragging the cable pre-connected to the support body 200, and the locking mechanism 300 on the support body 200 is removed and waits for reuse.

[0069] This method is simple and convenient to operate, and can easily solve the problem of sand around the suction cylinder foundation 100 being easily washed away. The combination of the anti-scour cloth 500's cloth ring structure and the support member 400's weight structure can effectively suppress the sand around the suction cylinder foundation 100, preventing it from being washed away by ocean currents and other factors, thereby reducing the formation of potholes and maintaining the stability of the suction cylinder foundation 100. Moreover, the anti-scour cloth 500 and the support member 400 are simple and convenient to install, do not require complex construction equipment, and help reduce the difficulty and time cost of offshore operations.

[0070] Furthermore, the support body 200 and locking mechanism 300 can be disassembled and recycled for secondary use, reducing resource waste and offering environmental benefits by minimizing secondary damage to the marine environment. Furthermore, the support body 200 and locking mechanism 300 can adapt to different types of suction cylinder foundations 100, improving their versatility in various operations.

[0071] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
