Description

Technical Field

[0002] With the advancement of technology and the pressure of climate change, offshore wind power generation has become an important way to replace fossil fuels. Offshore wind power can not only provide renewable clean energy and reduce carbon emissions, but also can be built away from densely populated areas to reduce the impact on residents' lives.

[0003] As a type of offshore wind farm foundation, suction tube foundation is widely used due to its advantages of quick installation and little environmental disturbance. However, in actual use, due to the influence of natural factors such as ocean currents, the sand around the suction tube foundation is easily washed away, resulting in pits around the suction tube foundation, which reduces the buried depth of the suction tube foundation and seriously reduces the anti-overturning ability of the suction tube foundation. This problem significantly affects the stability and safety of the suction tube foundation.

[0004] At present, in order to solve the scouring problem, common measures include laying anti-scouring stones, concrete bags or other materials around the suction tube foundation to reduce the loss of sand. However, these methods have limited effects and short duration, and cannot completely solve the problem of potholes caused by scouring.

[0050] In one embodiment, the first support assembly 210 includes a hinged portion 211 and a connecting portion 212, and a plurality of support monomers 213 are connected between the hinged portion 211 and the connecting portion 212.

[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, thereby, the recovery screw 325 connects and fixes the first shell 321 and the second shell 322, and realizes 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 connection 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, so as to drive the first positioning rod 314 and the second positioning rod 315 to rotate relatively close to each other, so that the abutment 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 and fix the support body 200 on the suction cylinder foundation 100, thereby realizing 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-scouring cloth 500 is installed around the outside of the suction cylinder foundation 100, and the anti-scouring cloth 500 is connected and fixed to the support member 400 so that the anti-scouring cloth 500 is kept in a horizontal and flat state;

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

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

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

[0069] The method is simple and convenient to operate, and can easily solve the problem that the sand around the suction cylinder foundation 100 is easily washed away. The combination of the cloth ring structure of the anti-scouring cloth 500 and the heavy structure of the support member 400 can effectively press the sand around the suction cylinder foundation 100 to prevent it from being washed away due to ocean currents and other reasons, thereby reducing the formation of potholes and maintaining the stability of the suction cylinder foundation 100. Moreover, the installation and operation of the anti-scouring cloth 500 and the support member 400 are simple and convenient, and do not require complex construction equipment, which is conducive to reducing the difficulty and time cost of offshore operations.

[0070] In addition, the support body 200 and the locking mechanism 300 can be disassembled and recycled for secondary use, which reduces the waste of resources, has environmental benefits, and reduces secondary damage to the marine environment. Furthermore, the support body 200 and the locking mechanism 300 can also adapt to different types of suction cylinder foundations 100, improving the versatility in various operations.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
