DETAILED DESCRIPTION

[0018] The technical solutions of the present application are further described below, but the scope of protection is not limited to the description.

[0019] As Figs. 1 to 4 shown.

[0020] The application discloses a floating type offshore wind power suction anchor auxiliary construction device. The lifting appliance 1 is connected with the top surface of the suction anchor 12 and provides force connection during lifting and installation of the suction anchor 12.

[0021] The monitoring assembly 2 is installed on the top outer periphery of the suction anchor 12 and detects and obtains the inclination data of the suction anchor 12.

[0022] The leveling assembly 3 is installed on the bottom outer periphery of the suction anchor 12 and applies auxiliary force to the suction anchor 12 to assist in adjusting the suction anchor 12 to the vertical state to contact the seabed and be adsorbed.

[0023] The rubber pad 7 is fixed on the bottom surface of the suction anchor 12 and provides elastic buffering to contact the seabed.

[0024] The crane of the work ship or work platform is connected with the lifting appliance 1 on the top surface of the suction anchor 12, the suction anchor 12 is lifted and lowered into the sea, when the bottom surface of the suction anchor 12 inclines to contact the seabed through the rubber pad 7, the monitoring assembly 2 detects and obtains the inclination data of the suction anchor 12, and the suction anchor 12 is adjusted to the vertical state through the leveling assembly 3 during the process of sinking into the sea by negative pressure, so that the problem that the inclination data of the suction anchor cannot be obtained and the suction anchor cannot be adjusted is solved.

[0025] The lifting appliance 1 comprises a plurality of lifting pieces and a collection body for collecting the lifting pieces. The bottom of the plurality of lifting pieces is fixedly connected with a plurality of locking rings 11 on the top of the suction anchor 12, and the top of the plurality of lifting pieces is fixedly connected with the collection body.

[0026] The monitoring assembly 2 comprises a fixed rod 21 fixedly connected in the middle of the lifting appliance 1, a plurality of supporting rods 22 fixedly connected at the end of the fixed rod 21, a plurality of positioning rings 23 fixedly connected at the end of the supporting rods 22, a plurality of positioning rods 24 fixedly connected with the inner side wall of the positioning ring 23, a moving groove 25 formed in the middle of the positioning rod 24, a spring 26 fixedly connected at the end of the moving groove 25, a top rod 27 fixedly connected at the end of the spring 26, the top rod 27 being slidingly connected in the middle of the positioning rod 24, a movement sensor 28 installed at the end of the positioning rod 24, and the movement sensor 28 being connected with a data receiving terminal on the sea surface through wired or wireless communication.

[0027] When the anchor body 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 anchor body 12. Due to the uneven distribution of soil layers on the seabed, the anchor body 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 anchor body 12 during its descent, quickly and accurately capturing minute changes in the anchor body 12 during descent and allowing for timely adjustments to ensure that the anchor body 12 is accurately and stably installed in the predetermined position.

[0028] The leveling component 3 includes multiple slide rails 31; the multiple slide rails 31 are fixedly connected to the outer wall of the anchor body 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 anchor body 12 on the rotating seat 33; a scraper 35 is fixedly connected to the bottom of the connecting plate 34.

[0029] During the sinking process of the anchor body 12, the scraper 35 first contacts the sinking position of the anchor body 12. At this time, the bottom of the anchor body 12 continues to sink and contacts the inner side of the connecting plate 34. The anchor body 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 through the slider 32. The scraper 35 moves simultaneously to level the ground, keeping the bottom sinking position of the anchor body 12 flat. The above structure can level the uneven ground at the sinking position of the anchor body 12, so that the anchor body 12 is subjected to uniform force during installation, reducing the tilting or uneven sinking of the anchor body 12 due to uneven foundation, and maintaining the overall vertical stability of the anchor body 12 during installation. The suction anchor 12 is assisted in being adjusted to an upright state by the leveling component 3.

[0030] 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 anchor body 12.

[0031] When the connecting plate 34 moves to the top of the slide rail 31 via the slider 32, it stops. The connecting plate 34 sinks into the ground along with the anchor body 12. The sliding plate 41, which is squeezed by the outer wall of the anchor body 12, slides in the middle of the connecting plate 34 and contacts the side wall of the anchor body 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 anchor body 12 through the sliding plate 41. The above structure can provide an additional support for the anchor body 12, effectively increase the contact area between the anchor body 12 and the seabed, effectively utilize the bearing capacity of the seabed soil, and enable the anchor body 12 to maintain sufficient stability and durability in the deep sea environment.

[0032] 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.

[0033] During operation, as the anchor body 12 continues to sink, it first comes into contact with the ball bearing 51. As the anchor body 12 moves, the ball bearing 51 rotates in the middle of the base 5. This structure effectively reduces the frictional resistance between the anchor body 12 and the connecting plate 34, reduces the problem of jamming when the anchor body 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.

[0034] 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.

[0035] During operation, seabed geology varies. When the installation location has hard geology, the scraper blade 6 scrapes the surface as the scraper blade 35 moves. This structure can adapt to various complex seabed topography, reduce the resistance encountered by the anchor body 12 during installation, and improve the performance of the scraper blade 35 during use.

[0036] Working principle: During the installation of the suction anchor, the end of the lifting device 1 is first installed on the top of the anchor body 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 anchor body 12 is then lowered into the seabed using lifting equipment. As the anchor body 12 continues to descend into the seabed, its position is monitored by the monitoring component 2. When the anchor body 12 enters the seabed soil, the designated position is first leveled by the leveling component 3, allowing the anchor body 12 to descend onto a flat seabed surface. The end of the top rod 27 is then connected to the anchor body 1. 2. Surface fit: Four top rods 27 are provided, corresponding to different directions of the anchor body 12. During the process of the anchor body 12 descending or entering the ground, when the anchor body 12 shifts or tilts, the anchor body 12 presses against 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, enabling the operator to quickly adjust the anchor body 12. As the anchor body 12 sinks, the scraper 35 first contacts the sinking position of the anchor body 12. At this time, the bottom of the anchor body 12 continues to sink and contacts the inner side of the connecting plate 34. The anchor body 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, the connecting plate 34 moves upward in the middle of the slide rail 31 through the slider 32 during the rotation. The scraper 35 moves at the same time to scrape the ground flat, so that the bottom sinking position of the anchor body 12 remains 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 anchor body 12.

[0037] The sliding plate 41, which is squeezed by the outer wall of the anchor body 12, slides in the middle of the connecting plate 34 and contacts the side wall of the anchor body 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 anchor body 12 through the sliding plate 41. When the anchor body 12 continues to sink, the anchor body 12 first comes into contact with the rolling ball 51. During the movement of the anchor body 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 of the anchor body 12, the rubber pad 7 first comes into contact with the ground and absorbs the impact generated by the direct contact between the anchor body 12 and the ground.
