During the installation process, weak soil layers or cavities can cause the suction anchor to sink unstably, resulting in tilting during the sinking process. However, existing technologies cannot obtain the tilt data of the suction anchor and make auxiliary adjustments. Summary of the Invention

Detailed Implementation

[0025] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0026] like Figures 1 to 4 As shown.

[0027] This application discloses a floating offshore wind power suction anchor auxiliary construction device, comprising:

[0028] The lifting device 1 is connected to the top surface of the suction anchor 12 for hoisting. The lifting device 1 provides a force connection during the hoisting and installation process of the suction anchor 12.

[0029] The monitoring component 2 is installed on the outer periphery of the top of the suction anchor 12. The monitoring component 2 detects and acquires the tilt data of the suction anchor 12.

[0030] The leveling component 3 installed on the outer periphery of the bottom of the suction anchor 12 applies an auxiliary force to the suction anchor 12 to help adjust it to an upright position so that it can contact the seabed for adsorption.

[0031] The bottom surface of the suction anchor 12 is fixed with a rubber pad 7, which provides elastic cushioning to contact the seabed.

[0032] The crane of the working vessel or platform is connected to the lifting device 1 on the top surface of the suction anchor 12. The suction anchor 12 is lifted into the sea. When the bottom surface of the suction anchor 12 contacts the seabed with the rubber pad 7 and tilts, the monitoring component 2 detects and obtains the tilt data of the suction anchor 12. During the negative pressure sinking process of the suction anchor 12 in contact with the seabed, the suction anchor 12 is assisted in adjusting to the vertical state through the leveling component 3, which solves the problem of not being able to obtain the tilt data of the suction anchor and perform auxiliary adjustment.

[0033] The lifting device 1 includes multiple lifting components and a collection body for the lifting components. The bottom of the multiple lifting components is fixedly connected to multiple locking rings 11 on the top of the suction anchor 12, and the tops of the multiple lifting components are collected on the collection body for fixed connection.

[0034] The monitoring component 2 includes a fixed rod 21 fixedly connected to the middle of the spreader 1. Multiple support rods 22 are fixedly connected to the end of the fixed rod 21, and positioning rings 23 are fixedly connected to the ends of the multiple support rods 22. Multiple positioning rods 24 are fixedly connected to the inner side wall of the positioning rings 23. A moving groove 25 is opened in the middle of the positioning rod 24. A spring 26 is fixedly connected to the end of the moving groove 25. A top rod 27 is fixedly connected to the end of the spring 26. The top rod 27 is slidably connected to the middle of the positioning rod 24. A motion sensor 28 is installed at the end of the positioning rod 24. The motion sensor 28 is connected to a data receiving terminal on the sea surface via wired or wireless communication.

[0035] When the suction anchor 12 deviates or tilts as it enters the seabed, it presses against the top rod 27 on the tilted side, causing the top rod 27 to slide inward toward the positioning rod 24. The corresponding side then loosens, and the top rod 27 moves outward through the elastic movement groove 25. When the top rod 27 moves inward or outward, the movement sensor 28 promptly sends a monitoring signal, allowing the operator to quickly adjust the suction anchor 12. Due to the uneven distribution of soil layers on the seabed, the suction anchor 12 is prone to tilting during descent. The combined use of the top rod 27 and the movement sensor 28 enables real-time monitoring of the suction anchor 12 during its descent. This allows for rapid and accurate capture of minute changes in the suction anchor 12 during descent, enabling timely adjustments to ensure that the suction anchor 12 is accurately and stably installed in the predetermined position.

[0036] The leveling component 3 includes multiple slide rails 31; the multiple slide rails 31 are fixedly connected to the outer wall of the suction anchor 12; a slider 32 is installed in the middle of the slide rail 31; a rotating seat 33 is installed in the middle of the slider 32; a connecting plate 34 is installed in the middle of the rotating seat 33; the connecting plate 34 is arc-shaped; a torsion spring is provided at the connection between the connecting plate 34 and the rotating seat 33, so that the connecting plate 34 can only rotate outward relative to the suction anchor 12 on the rotating seat 33; a scraper 35 is fixedly connected to the bottom of the connecting plate 34.

[0037] As the suction anchor 12 sinks, the scraper 35 first contacts the sinking position of the suction anchor 12. At this time, the bottom of the suction anchor 12 continues to sink and contacts the inner side of the connecting plate 34. The suction anchor 12 continuously applies pressure to one side of the connecting plate 34, causing the connecting plate 34 to rotate outward in the middle of the rotating seat 33. At the same time, during the rotation, the connecting plate 34 moves upward in the middle of the slide rail 31 via the slider 32. The scraper 35 moves simultaneously to level the ground, keeping the bottom sinking position of the suction anchor 12 flat. This structure can level uneven ground at the sinking position of the suction anchor 12, ensuring that the suction anchor 12 receives uniform force during installation. This reduces the risk of tilting or uneven sinking of the suction anchor 12 due to uneven foundation, maintaining the overall vertical stability of the suction anchor 12 during installation. The leveling component 3 helps to adjust the suction anchor 12 to an upright position.

[0038] The connecting plate 34 is slidably connected to the sliding plate 41 in the middle, and the sliding plate 41 is fixedly connected to the push plate 42, which is located between the connecting plate 34 and the suction anchor 12.

[0039] When the connecting plate 34 moves to the top of the slide rail 31 via the slider 32, it stops. As the suction anchor 12 sinks into the ground, the connecting plate 34 slides in the middle of the connecting plate 34 under the pressure of the outer wall of the suction anchor 12. It contacts the side wall of the suction anchor 12 through the push plate 42. At the same time, the sliding plate 41 that has entered the ground protrudes from one side of the connecting plate 34 and enters the soil around the suction anchor 12. The above structure can provide an additional support for the suction anchor 12, effectively increase the contact area between the suction anchor 12 and the seabed, effectively utilize the bearing capacity of the seabed soil, and enable the suction anchor 12 to maintain sufficient stability and durability in the deep sea environment.

[0040] Two bases 5 are fixedly connected to the middle of the connecting plate 34; a ball 51 is rotatably connected to the middle of the base 5.

[0041] During operation, as the suction anchor 12 continues to sink, it first comes into contact with the ball bearing 51. As the suction anchor 12 moves, the ball bearing 51 rotates in the middle of the base 5. This structure effectively reduces the frictional resistance between the suction anchor 12 and the connecting plate 34, reduces the problem of jamming when the suction anchor 12 and the connecting plate 34 come into contact, makes the connecting plate 34 move more smoothly, and effectively improves the efficiency of the scraper 35 in scraping the ground.

[0042] Multiple scrapers 6 are fixedly connected to the middle of the scraper 35; the multiple scrapers 6 are fixedly connected to the side away from the pusher plate 42.

[0043] During operation, the seabed geology varies. When the geology at the installation location is relatively hard, the scraper 35 scrapes the seabed with the scraper 6. The above structure can adapt to various complex seabed topography, reduce the resistance encountered by the suction anchor 12 during installation, and improve the performance of the scraper 35 during use.

[0044] Working principle: During the installation of the suction anchor, the end of the lifting device 1 is first installed on top of the suction anchor 12, connecting the end of the lifting device 1 to multiple locking rings 11. The lifting device 1 is then locked and fixed using the locking rings 11. The suction anchor 12 is then lowered into the seabed using lifting equipment. As the suction anchor 12 continues to descend into the seabed, its position is monitored by the monitoring component 2. When the suction anchor 12 enters the seabed soil, the designated position is first leveled by the leveling component 3, allowing the suction anchor 12 to descend onto a flat seabed surface. The end of the top rod 27 is then connected to the suction anchor 12. 2. Surface fit: There are four top rods 27, corresponding to different directions of the suction anchor 12. During the process of the suction anchor 12 descending or entering the ground, when the suction anchor 12 deviates or tilts, the suction anchor 12 squeezes the top rod 27 on the tilted side, causing the top rod 27 to slide inward into the positioning rod 24. The corresponding side is loosened, and the top rod 27 is moved outward through the elastic movement groove 25. When the top rod 27 moves inward or outward, the movement sensor 28 promptly sends out monitoring signal data, so that the operator can quickly adjust the suction anchor 12.

[0045] As the suction anchor 12 sinks, the scraper 35 first contacts the sinking position of the suction anchor 12. At this time, the bottom of the suction anchor 12 continues to sink and contacts the inner side of the connecting plate 34. The suction anchor 12 continues to apply pressure to one side of the connecting plate 34, causing the connecting plate 34 to rotate outward in the middle of the rotating seat 33. At the same time, during the rotation, the connecting plate 34 moves upward in the middle of the slide rail 31 through the slider 32. The scraper 35 moves simultaneously to flatten the ground, keeping the bottom sinking position of the suction anchor 12 flat. When the connecting plate 34 moves to the top of the slide rail 31 through the slider 32, it stops. The connecting plate 34 sinks into the ground along with the suction anchor 12.

[0046] The sliding plate 41, which is squeezed by the outer wall of the suction anchor 12, slides in the middle of the connecting plate 34 and contacts the side wall of the suction anchor 12 through the push plate 42. At the same time, the sliding plate 41, which enters the ground, protrudes from one side of the connecting plate 34 and enters the soil around the suction anchor 12 through the sliding plate 41. When the suction anchor 12 continues to sink, the suction anchor 12 first comes into contact with the rolling ball 51. During the movement of the suction anchor 12, the rolling ball 51 rotates in the middle of the base 5. There are differences in seabed geology. When the geology at the installation location is hard, it is scraped by the scraper 6 as the scraper 35 scrapes it. During the installation and sinking process of the suction anchor 12, the rubber pad 7 first contacts the ground and absorbs the impact generated by the direct contact between the suction anchor 12 and the ground.
