Description

Technical Field

[0001] This invention relates to the field of marine wind power technology, specifically to a novel deep-water jacket structure and installation method for marine wind power systems. Background Technology

[0002] Offshore wind power refers to the technology and system for generating electricity using offshore wind energy. Compared with onshore wind power, offshore wind power can take advantage of higher and more stable wind speeds at sea to improve power generation efficiency. Offshore wind farms are usually built in coastal areas or far offshore, generating electricity by rotating the blades of wind turbines driven by wind power. Offshore wind turbine jackets are a basic structure for offshore wind turbines, mainly used for the installation of wind turbine units in deep water areas. The jacket foundation is made of multiple steel pipes welded or bolted together to form a triangular or quadrilateral mesh frame structure.

[0003] For example, in the "Underwater Jacket for Offshore Wind Power" with publication number CN118498420A, the bottom of the frame is fixed with a bottom fixing mechanism. The bottom fixing mechanism is equipped with a skeleton assembly and a first concrete storage mechanism. After the frame is built on the seabed, under the action of the frame's own weight, the skeleton assembly moves into place to form the first skeleton, and then the bottom skeleton is formed by pouring concrete inside the first concrete storage mechanism. After the offshore wind power generation tower is fixedly installed on the top of the frame, under the action of the offshore wind power generation tower's weight, the bottom of the frame retracts into the slot, and the second skeleton on the frame forms the top skeleton by pouring concrete inside the second concrete storage mechanism. At the same time, under the tension of the limiting column, the pull rope pulls the flap to a horizontal state, so that the flap is horizontally embedded into the seabed.

[0004] However, in existing technologies, when the jacket is installed on the seabed, it is prone to tilting due to geological conditions. This changes the jacket's center of gravity and reduces its stability on the seabed. Especially under the influence of external forces such as ocean currents and waves, tilting can further increase the risk of collapse or displacement. In addition, tilting can also affect the installation accuracy of the jacket's superstructure, which can easily cause the platform or other facilities to tilt, thereby affecting the normal operation of the equipment and the safety of personnel. Tilting can also lead to uneven stress on the jacket, and some structural parts are prone to being subjected to pressure or shear force beyond the design range. Over time, this can easily lead to local fatigue, damage, or even breakage. Summary of the Invention

[0005] The purpose of this invention is to provide a novel deep-water jacket foundation and installation method for use in offshore wind power systems, in order to solve the problem mentioned in the background art that the jacket foundation is prone to tilting due to geological conditions, which changes the center of gravity of the jacket foundation and reduces its stability on the seabed.

[0011] Preferably, a second mounting bracket is installed on one side of the first hydraulic cylinder, the bottom of the second mounting bracket is fixedly connected to the top of the base, and the middle part of the linkage rod is rotatably connected to the transmission rod.

[0012] Preferably, the second connecting mechanism includes a mounting base and a second mounting sleeve. The side wall of the second mounting sleeve is fixedly connected to a fixing rod. The bottom of the mounting base is fixedly connected to the top of the first guide frame. A locking ring is fixedly connected to the inner side of the top of the mounting base. A lifting sleeve is slidably connected to the inner side of the second mounting sleeve. A second limiting rod is rotatably connected to the inner side of the lifting sleeve. A limiting head is fixedly connected to the outer wall of the bottom end of the second limiting rod.

[0013] Preferably, the bottom end of the limiting head is engaged with the locking ring, the top side wall of the lifting sleeve is fixedly connected with a first limiting rod, and limiting holes are opened on both sides of the second mounting sleeve, with the limiting holes slidably connected to the first limiting rod.

[0014] Preferably, the top of the second mounting sleeve is symmetrically fixedly connected with mounting blocks, and the inner sides of the two mounting blocks are rotatably connected with second threaded rods. The bottom end of the second threaded rod is rotatably connected to the top of the lifting sleeve, and the outer surface of the top end of the second threaded rod is threadedly connected with a rotating sleeve.

[0015] Preferably, the first connecting mechanism includes a fixing block and a first mounting sleeve. The bottom of the fixing block is fixedly connected to the top of the first guide frame. The side wall of the first mounting sleeve is fixedly connected to a fixing rod. A driving block is slidably connected to the inner side of the fixing block. One end of the driving block has an inclined surface. A fixing column is fixedly connected to the center of the top of the fixing block. A lifting rod is slidably connected to the inner side of the fixing column. The bottom end of the lifting rod contacts the inner side of the inclined surface. Limit frames are rotatably connected to both sides of the fixing column.

[0016] Preferably, the bottom end of the first mounting sleeve is provided with a second insertion groove, and two third insertion rods are symmetrically fixedly connected to the top of the fixing block. The third insertion rods are inserted into the second insertion groove. A limit plate is fixedly connected to the inner side of the first mounting sleeve, and the limit frame is engaged with the limit plate. A second hydraulic cylinder is fixedly connected to the side wall of the fixing block. The output end of the second hydraulic cylinder is fixedly connected to the drive block, and one end of the limit frame is located inside the lifting rod.

[0017] A novel deep-water jacket installation method for offshore wind power systems includes the following steps:

[0018] Step 1: Assemble the guide frame. The second guide frame is pre-connected to the first guide frame via the second insertion rod and the first insertion slot. Then, the second connecting mechanism is used for connection. During the insertion process, the second mounting sleeve moves together with the fixing rod, causing the second limiting rod to insert into the groove at the top of the mounting base. The limiting head is ready to insert into the inside of the locking ring.

[0019] Step 2: Adjust the connection position. Rotate the second threaded rod to adjust its position, thereby pushing the lifting sleeve to move and causing the first limiting rod to move within the limiting hole. This causes the lifting sleeve to move downwards. When the limiting head is inserted into the bottom of the locking ring, the elastic second limiting rod begins to recover, causing the limiting head to lock the locking ring, thus completing the locking of the mounting base on the second mounting sleeve and the second limiting rod.

[0020] Step 3: Reinforce the connection. The fixing rod drives the first mounting sleeve to move, so that the second insertion slot at its bottom can be inserted into the third insertion rod. The second hydraulic cylinder drives the drive block to move, and the inclined plane pushes the lifting rod upward, so that the limit frame applies pressure to the limit plate to complete the connection between the first mounting sleeve and the fixing block.

[0021] Step 4: Real-time monitoring and adjustment. Sensors are installed on the base and the first guide frame to monitor the structural status and environmental parameters in real time. When the first and second guide frames become misaligned, the adjustment mechanism can be used for adjustment. The first hydraulic cylinder controls the movement of the linkage rod, which in turn moves the two transmission rods, transmitting the force to the third rotating frame. Through the coordinated action of the three swing rods, combined with the cooperation of the first and second rotating frames, the angle of the first guide frame is effectively adjusted.

[0022] Step 5: Adaptive Anchoring. Based on the seabed topography and geological conditions, adjust the anchoring depth and angle of the plug-in rod. Drive the threaded rod to rotate via the second waterproof motor, and the lifting plate moves to drive the sliding rod, pushing the plug-in rod to the designated position. At the same time, the first waterproof motor drives the worm gear to rotate, precisely adjusting the anchoring angle of the plug-in rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, by combining sensor technology and mechanical adjustment mechanisms, adaptive adjustment and stability monitoring of the seabed structure are achieved to predict potential risks and ensure system safety and stability. Through the coordinated work of multiple linkage parts, precise adjustment of the jacket is achieved. The activation of the first hydraulic cylinder causes the linkage rod to move, and the force is transmitted to the third rotating frame through the transmission rod, which in turn acts on the swing rod to coordinately adjust the angle of the jacket, thereby maintaining the stability of the overall structure. In addition, the anchoring depth and angle of the plug rod are adjusted according to the seabed topography and geological conditions. The second waterproof motor drives the threaded rod to rotate, and the lifting plate moves to drive the sliding rod, pushing the plug rod to the designated position. At the same time, the first waterproof motor drives the worm gear to rotate, precisely adjusting the anchoring angle of the plug rod. This not only improves the reliability and stability of the anchoring, but also ensures the flexibility and adaptability of the system in complex seabed environments.

[0025] 2. In this invention, a second connecting mechanism is used during the connection of the second guide frame and the first guide frame to ensure the stability and firmness of the connection. The connection process begins with the insertion of the second insertion rod into the first insertion slot. Accompanied by the movement of the fixing rod, the movement of the second mounting sleeve causes the second limiting rod to smoothly insert into the groove of the mounting base. At the same time, the limiting head prepares to insert into the locking ring, preparing for subsequent locking. After the second mounting sleeve is inserted into the top of the mounting base, the limiting head is not fully engaged with the locking ring. At this time, the operator can further push the connection process by rotating the second threaded rod. The rotation of the threaded rod effectively controls its position, pushes the lifting sleeve to move, and the movement of the lifting sleeve guides the first limiting rod to move within the limiting hole and causes it to move vertically downward. Finally, the limiting head inserts into the bottom of the locking ring, and the elastic second limiting rod returns to its original position and locks the locking ring, thereby completing a firm connection. This connection mechanism improves the convenience of operation and the overall strength of the structure. The design of the threaded rod and the lifting sleeve gives the connection process adjustability, allowing fine-tuning of the connection tightness according to environmental requirements, ensuring adaptability and safety under various usage conditions.

[0026] 3. In this invention, through the efficient operation of the second connecting mechanism, the movement of the fixing rod drives the first mounting sleeve to smoothly connect with the third insertion rod. After the connection is completed, the second hydraulic cylinder drive block is activated, pushing the lifting rod upward and applying force to the limiting frame, causing it to start rotating. One end of the limiting frame presses against the limiting plate, locking the limiting plate and thus completing the connection between the first mounting sleeve and the fixing block. This connection process significantly enhances the stability between the second and first guide frames. In the overall structure, the first connecting mechanism is responsible for locking the second guide frame, while the second connecting mechanism locks the second guide frame onto the first guide frame, forming a two-way locking mechanism. This not only improves the stability of the connection but also ensures the reliability of the structure under various operating environments. The two-way locking also improves the ease of operation, making the connection and disassembly process more efficient, thereby saving time and labor costs. Through this innovative design, the connection between the first mounting sleeve and the fixing block ensures strength while improving the seismic resistance and durability of the overall structure. In extreme seabed environments and complex working conditions, the two-way locking mechanism ensures a stable connection between the second and first guide frames, providing a strong guarantee for the long-term stable operation of the system.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Refer to Figure 1 - Figure 5 As shown: A novel deep-water jacket foundation and installation method for offshore wind power systems, comprising a first jacket foundation 4, a second jacket foundation 5, and a base 1. A fixing rod 51 is fixedly connected to the inner wall of the bottom end of the second jacket foundation 5. A first insertion groove 41 is opened on the top of the first jacket foundation 4. A second insertion rod 52 is fixedly connected to the bottom end of the second jacket foundation 5 and is inserted into the first insertion groove 41. Anchoring mechanisms 2 are installed on both sides of the base 1, and an adjustment mechanism 3 is installed on the top of the base 1. A first connecting mechanism 6 is installed on both sides of the top of the first jacket foundation 4, and a second connecting mechanism 7 is installed on the top of the first jacket foundation 4.

[0038] The anchoring mechanism 2 includes a first mounting frame 21. A first fixed frame 211 is fixedly connected to the center of one side of the first mounting frame 21. Mounting shells 231 are rotatably connected to both sides of the first fixed frame 211. The mounting shells 231 are fixedly connected to the side wall of the first mounting frame 21. A worm gear 28 is rotatably connected to the inner side of the first fixed frame 211. Worm wheels 29 are meshed on both sides of the worm gear 28. The worm wheels 29 are fixedly connected to the side wall of the mounting shell 231. A first threaded rod 23 is rotatably connected to the bottom of the mounting shell 231. A lifting plate 24 is threadedly connected to the outer surface of the first threaded rod 23. A first plug-in rod 25 is fixedly connected to the bottom of the lifting plate 24.

[0039] The adjustment mechanism 3 includes three swing rods 32. A first rotating frame 33 is rotatably connected to the top of each swing rod 32. A second rotating frame 34 is rotatably connected to the outside of the first rotating frame 33. The top of the second rotating frame 34 is fixedly connected to the bottom of the first guide frame 4. A third rotating frame 35 is rotatably connected to the bottom of each swing rod 32. Two transmission rods 36 are rotatably connected to the bottom of the third rotating frame 35. Linkage rods 37 are provided on both sides of each transmission rod 36. The two linkage rods 37 are rotatably connected to each other. A first hydraulic cylinder 31 is rotatably connected to the other end of each linkage rod 37. Four telescopic rods 39 are provided on the top of the base 1. Connecting frames 391 are rotatably connected to the top and bottom of each telescopic rod 39. A fixing plate 27 is fixedly connected to the side wall of the mounting housing 231. A sliding rod 26 is fixedly connected to one side of the top of the lifting plate 24. The top of the sliding rod 26 passes through the fixing plate 27, and the sliding rod 26 is slidably connected to the fixing plate 27. A first waterproof motor 22 is installed on the top of the first fixing frame 211. The output end of the first waterproof motor 22 is fixedly connected to the worm gear 28. A second waterproof motor 232 is installed inside the mounting housing 231. The output end of the mounting housing 231 is fixedly connected to the first threaded rod 23. A second mounting frame 38 is installed on one side of the first hydraulic cylinder 31. The bottom of the second mounting frame 38 is fixedly connected to the top of the base 1. The middle part of the linkage rod 37 is rotatably connected to the transmission rod 36.

[0040] In this embodiment, during installation, sensors are first installed on the base 1 and the first guide frame 4 to monitor the structural status and environmental parameters in real time. The sensors collect data and analyze it to predict potential risks, ensuring the safety and stability of the entire system. When the first guide frame 4 and the second guide frame 5 become misaligned, adjustment can be made using the adjustment mechanism 3. The adjustment process is completed by the coordinated action of multiple mechanisms. First, the first hydraulic cylinder 31 is activated to control the movement of the linkage rod 37. As the linkage rod 37 moves, the force is transmitted through the transmission rod 36, and the movement of the two transmission rods 36 further transmits the force to the third rotating frame 35. At this time, the third rotating frame 35 then transmits the force to the swing rod 32. Through the coordinated action of the three swing rods 32, the first rotating frame 33 and the second rotating frame 34 also cooperate, ensuring the smooth progress of the entire adjustment process. This series of actions ultimately changes the angle of the first guide frame 4, ensuring that the angles of the first guide frame 4 and the second guide frame 5 can be adjusted at any time, achieving adaptive adjustment and thus guaranteeing the overall stability of the structure.

[0041] Furthermore, the system can further adjust the anchoring depth and angle of the first connector 25 based on the seabed topography and geological conditions. During depth adjustment, the second waterproof motor 232 drives the first threaded rod 23 to rotate, which controls the lifting and lowering of the lifting plate 24. During the movement of the lifting plate 24, it moves the sliding rod 26, thereby pushing the first connector 25 into the designated anchoring position. To ensure the accuracy of the anchoring angle, the system can utilize the first waterproof motor 22 to drive the rotation of the worm gear 28. The rotation of the worm gear 28 simultaneously applies force to the two worm wheels 29, and the rotation of the worm wheels 29 drives the two mounting shells 231 to rotate respectively, thereby precisely adjusting the anchoring angle of the first connector 25. This design allows for adaptive angle adjustments based on different geological conditions, thereby improving the reliability and stability of the anchoring.

[0042] Combining sensor technology and mechanical adjustment mechanisms, the system can automatically adjust the structure's state based on real-time monitoring data, ensuring both the stability of the device and providing flexibility and precision to adapt to complex seabed environments. By precisely controlling the anchoring depth and angle, the system can ensure stable and reliable support under various geological conditions.

[0043] Example 2: Figure 6 As shown, the second connecting mechanism 7 includes a mounting base 75 and a second mounting sleeve 71. The side wall of the second mounting sleeve 71 is fixedly connected to the fixing rod 51. The bottom of the mounting base 75 is fixedly connected to the top of the first guide frame 4. A locking ring 76 is fixedly connected to the inner side of the top of the mounting base 75. A lifting sleeve 74 is slidably connected to the inner side of the second mounting sleeve 71. A second limiting rod 77 is rotatably connected to the inner side of the lifting sleeve 74. A limiting head 771 is fixedly connected to the outer wall of the bottom end of the second limiting rod 77. The bottom end of the limiting head 771 is engaged with the locking ring 76. A first limiting rod 741 is fixedly connected to the side wall of the top of the lifting sleeve 74. Limiting holes 711 are opened on both sides of the second mounting sleeve 71, and the limiting holes 711 are slidably connected to the first limiting rod 741. Mounting blocks 72 are symmetrically fixedly connected to the top of the second mounting sleeve 71. A second threaded rod 73 is rotatably connected to the inner side of the two mounting blocks 72. The bottom end of the second threaded rod 73 is rotatably connected to the top of the lifting sleeve 74. A rotating sleeve 731 is threadedly connected to the outer surface of the top of the second threaded rod 73.

[0044] In this embodiment, a second connecting mechanism 7 is used to ensure a stable connection between the second guide tube frame 5 and the first guide tube frame 4. The connection process begins with the insertion of the second insertion rod 52 into the first insertion slot 41. During insertion, the second mounting sleeve 71 moves with the movement of the fixing rod 51, allowing the second limiting rod 77 to smoothly insert into the groove at the top of the mounting base 75. Simultaneously, the limiting head 771 prepares to insert into the inner side of the locking ring 76, preparing for subsequent locking.

[0045] After the second mounting sleeve 71 is fully inserted into the top of the mounting base 75, the limiting head 771 at the bottom of the second limiting rod 77 is not fully inserted into the locking ring 76. At this time, the operator can begin to rotate the second threaded rod 73 to further advance the connection process. During rotation, the rotation of the second threaded rod 73 can effectively control the position of the second threaded rod 73, thereby pushing the lifting sleeve 74 to move. Simultaneously, for ease of operation, the second threaded rod 73 can be equipped with an installation handle, allowing the operator to operate more easily.

[0046] The movement of the lifting sleeve 74 guides the first limiting rod 741 to move within the limiting hole 711, causing the lifting sleeve 74 to move downwards in the vertical direction. As the limiting head 771 continues to move downwards, it eventually inserts into the bottom end of the locking ring 76. Once the limiting head 771 is successfully inserted, the elastic second limiting rod 77 begins to return to its original position. At this point, the limiting head 771 locks the locking ring 76, thus completing the locking of the mounting base 75 onto the second mounting sleeve 71 and the second limiting rod 77.

[0047] This series of connection steps ensures a robust and stable connection between the second guide frame 5 and the first guide frame 4. This design not only improves the convenience of the connection process but also enhances the overall strength and safety of the connected structure. Furthermore, the use of threaded rods and lifting sleeves 74 allows for a degree of adjustability in the connection process, enabling fine-tuning of the tightness as needed to adapt to different environments and operating conditions. Overall, this connection mechanism demonstrates good functionality and practicality, ensuring the stability and safety of the system during operation.

[0048] Example 3: According to Figure 7-8 As shown, the first connecting mechanism 6 includes a fixing block 62 and a first mounting sleeve 61. The bottom of the fixing block 62 is fixedly connected to the top of the first guide frame 4. The side wall of the first mounting sleeve 61 is fixedly connected to the fixing rod 51. A driving block 64 is slidably connected to the inner side of the fixing block 62. One end of the driving block 64 has an inclined surface 641. A fixing column 67 is fixedly connected to the center of the top of the fixing block 62. A lifting rod 65 is slidably connected to the inner side of the fixing column 67. The bottom end of the lifting rod 65 contacts the inner side of the inclined surface 641. Limiting frames 66 are rotatably connected to both sides of the fixing column 67. The bottom of the first mounting sleeve 61 is provided with a second insertion slot 611. Two third insertion rods 621 are symmetrically fixedly connected to the top of the fixing block 62. The third insertion rods 621 are inserted into the second insertion slot 611. A limit plate 612 is fixedly connected to the inner side of the first mounting sleeve 61. The limit frame 66 is snapped into the limit plate 612. A second hydraulic cylinder 63 is fixedly connected to the side wall of the fixing block 62. The output end of the second hydraulic cylinder 63 is fixedly connected to the drive block 64. One end of the limit frame 66 is located inside the lifting rod 65.

[0049] In this embodiment, through the effective operation of the second connecting mechanism 7, while fixing is completed, the fixing rod 51 will drive the first mounting sleeve 61 to move together, so that the second insertion slot 611 at the bottom of the first mounting sleeve 61 can be smoothly inserted into the third insertion rod 621. After the insertion is completed, the drive block 64 can be driven to move by activating the second hydraulic cylinder 63. The inclined surface 641 of the drive block 64 is designed to effectively push the lifting rod 65 to move.

[0050] During the movement of the lifting rod 65, it not only moves upward under the push of the drive block 64, but also applies a force to the limiting frame 66, causing the limiting frame 66 to begin rotating. After rotation, one end of the limiting frame 66 exerts a pressing force on the limiting plate 612, thus locking the limiting plate 612 and completing the connection between the first mounting sleeve 61 and the fixing block 62. This connection process plays an important role in reinforcing the connection between the second guide frame 5 and the first guide frame 4, and also significantly improves the strength of the connection.

[0051] In the overall structure, the first connecting mechanism 6 is responsible for locking the second guide tube frame 5 through the first guide tube frame 4, while the second connecting mechanism 7 is responsible for locking the second guide tube frame 5 to the first guide tube frame 4. This bidirectional locking mechanism further enhances the stability of the connection and ensures the reliability of the structure under various operating environments. In addition, the bidirectional locking design also improves the convenience of operation, making the connection and disassembly process more efficient and saving time and labor costs.

[0052] This design ensures not only the strength of the connection between the first mounting sleeve 61 and the fixing block 62, but also improves the overall structure's seismic resistance and durability. Whether in extreme seabed environments or under complex working conditions, the bidirectional locking mechanism ensures a stable connection between the second jacket 5 and the first jacket 4, guaranteeing the long-term stable operation of the system.

[0054] 1) Assemble the guide frame. The second guide frame 5 is pre-connected to the first guide frame 4) via the second insertion rod 52 and the first insertion slot 41. Then, the second connecting mechanism 7 is used for connection. During the insertion process, the second mounting sleeve 71 moves together with the fixing rod 51, causing the second limiting rod 77 to be inserted into the groove at the top of the mounting base 75. The limiting head 771 is ready to be inserted into the inside of the locking ring 76.

[0055] 2) Adjust the connection position, rotate the second threaded rod 73 to adjust the position of the second threaded rod 73, thereby pushing the lifting sleeve 74 to move, driving the first limiting rod 741 to move in the limiting hole 711, so that the lifting sleeve 74 moves downward. When the limiting head 771 is inserted into the bottom end of the locking ring 76, the elastic second limiting rod 77 begins to recover, so that the limiting head 771 locks the locking ring 76, thus completing the locking of the second mounting sleeve 71 and the second limiting rod 77 by the mounting seat 75.

[0056] 3) Reinforce the connection. The fixing rod 51 drives the first mounting sleeve 61 to move, so that the second insertion slot 611 at its bottom is inserted into the third insertion rod 621. The second oil cylinder 63 drives the driving block 64 to move, and the inclined surface 641 pushes the lifting rod 65 to move upward, so that the limiting frame 66 applies pressure to the limiting plate 612 to complete the connection between the first mounting sleeve 61 and the fixing block 62.

[0057] 4) Real-time monitoring and adjustment: Sensors are installed on the base 1 and the first guide frame 4 to monitor the structural status and environmental parameters in real time. When the first guide frame 4 and the second guide frame 5 are tilted as a whole, the adjustment mechanism 3 can be used for adjustment. The first hydraulic cylinder 31 controls the movement of the linkage rod 37, which causes the two transmission rods 36 to move, transmitting the force to the third rotating frame 35. Through the coordinated action of the three swing rods 32, combined with the cooperation of the first rotating frame 33 and the second rotating frame 34, the angle of the first guide frame 4 can be effectively adjusted.

[0058] 5) Adaptive anchoring: Adjust the anchoring depth and angle of the plug rod according to the seabed topography and geological conditions. Drive the threaded rod to rotate through the second waterproof motor 232, and the lifting plate 24 moves to drive the slide bar 26 to push the plug rod to the designated position. At the same time, the first waterproof motor 22 drives the worm gear 28 to rotate, and precisely adjust the anchoring angle of the plug rod.

[0059] The usage and working principle of this device are as follows: During installation, the second guide frame 5 and the first guide frame 4 are first assembled. The second connecting mechanism 7 is used to connect the second guide frame 5 and the first guide frame 4. The connection process begins with the second insertion rod 52 being inserted into the first insertion slot 41. During insertion, the second mounting sleeve 71 moves together with the fixing rod 51, causing the second limiting rod 77 to insert into the groove at the top of the mounting base 75. The limiting head 771 is ready to insert into the locking ring 76. As the second mounting sleeve 71 completes insertion into the top of the mounting base 75, the limiting head 771 is not fully inserted into the locking ring 76. At this time, the second threaded rod 73 can be rotated to adjust its position, pushing the lifting sleeve 74 to move, causing the first limiting rod 741 to move inside the limiting hole 711, thereby causing the lifting sleeve 74 to move downwards. After the limiting head 771 is inserted into the bottom of the locking ring 76, the elastic second limiting rod 77 begins to recover, causing the limiting head 771 to lock the locking ring 76, thereby completing the locking of the mounting base 75 onto the second mounting sleeve 71 and the second limiting rod 77.

[0060] While the second connecting mechanism 7 completes the fixing, the fixing rod 51 also drives the first mounting sleeve 61 to move, so that the second insertion slot 611 at its bottom engages with the third insertion rod 621. Subsequently, the second hydraulic cylinder 63 drives the driving block 64 to move, and the inclined surface 641 pushes the lifting rod 65 upward. When the lifting rod 65 moves, in addition to moving upward under the push of the driving block 64, it also applies a force to the limiting frame 66, causing the limiting frame 66 to start rotating. After rotating, one end of the limiting frame 66 applies pressure to the limiting plate 612 to lock the limiting plate 612, completing the connection between the first mounting sleeve 61 and the fixing block 62, thereby strengthening the connection between the second guide frame 5 and the first guide frame 4 and improving the connection's firmness.

[0061] The first connecting mechanism 6 locks the second guide tube frame 5 to the first guide tube frame 4, while the second connecting mechanism 7 locks the second guide tube frame 5 to the first guide tube frame 4. This bidirectional locking design further enhances the stability of the connection and improves the ease of operation.

[0062] First, sensors are installed on the base 1 and the first guide frame 4 to monitor the structural status and environmental parameters in real time, and to predict potential risks through data analysis. If the first guide frame 4 and the second guide frame 5 become misaligned, they can be adjusted using the adjustment mechanism 3. During the adjustment process, the first hydraulic cylinder 31 controls the movement of the linkage rod 37. When the linkage rod 37 starts to move, it transmits force to the transmission rod 36, causing the two transmission rods 36 to move, thereby transmitting force to the third rotating frame 35. At this time, the third rotating frame 35 transmits force to the swing rod 32. Through the coordinated action of the three swing rods 32, combined with the cooperation of the first rotating frame 33 and the second rotating frame 34, the angle of the first guide frame 4 can be effectively adjusted, so as to adjust the relative angle of the first guide frame 4 and the second guide frame 5 at any time and ensure overall stability.

[0063] Furthermore, the anchoring depth and angle of the first insertion rod 25 can be adjusted according to the seabed topography and geological conditions. During this adjustment process, the second waterproof motor 232 drives the first threaded rod 23 to rotate, thereby controlling the movement of the lifting plate 24. The lifting plate 24 drives the sliding rod 26 to move together, thus enabling the first insertion rod 25 to complete the insertion. When adjusting the angle, the first waterproof motor 22 drives the worm gear 28 to rotate. The worm gear 28 applies a force to the two worm wheels 29, causing the two worm wheels 29 to drive the two mounting shells 231 to rotate respectively, thereby controlling the angle of the first insertion rod 25 during the anchoring process and achieving adaptive adjustment to adapt to different geological conditions.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
