Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to a novel deep-water conductor frame applied to an offshore wind power system and an installation method thereof. Background Art

[0002] Offshore wind power refers to the technology and system for producing electricity using offshore wind energy. Compared with onshore wind power, offshore wind power can take advantage of higher and more stable offshore wind speeds to improve power generation efficiency. Offshore wind farms are usually built along the coast or in areas far offshore, and generate electricity by rotating the blades of wind turbines driven by wind. The offshore wind power conductor frame is a basic structure for offshore wind turbines, mainly used for the installation of wind turbines in deepwater areas. The conductor frame 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 "A Marine Wind Power Underwater Pipe Frame" with publication number CN118498420A, a bottom fixing mechanism is fixed to the bottom of the frame, and a skeleton assembly and a first concrete temporary storage mechanism are provided on the bottom fixing mechanism. After the frame is constructed on the seabed, under the action of the frame's own gravity, the skeleton assembly moves into position to form a first skeleton, and then the bottom skeleton is formed by pouring concrete inside the first concrete temporary storage mechanism; after the offshore wind power tower is fixedly installed on the top of the mounting frame, under the action of the gravity of the offshore wind power tower, the bottom of the mounting frame retracts into the slot, and the second skeleton on the mounting frame is formed into a top skeleton by pouring concrete inside the second concrete temporary 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 in the seabed.

[0004] However, in the prior art, when the jacket is installed on the seabed, it is easy to tilt due to the influence of geological conditions, which will change the center of gravity of the jacket and reduce its stability on the seabed. Especially under the influence of external forces such as ocean currents, wind and waves, the tilt is likely to further increase the risk of collapse or displacement. In addition, the tilt will also affect the installation accuracy of the jacket superstructure, and easily cause the platform or other facilities to tilt, thereby affecting the normal operation of the equipment and the safety of personnel. The tilt will also cause uneven force on the jacket, and some structural parts are prone to withstand pressure or shear force beyond the design range, which is likely to cause local fatigue, damage or even fracture in the long run. Summary of the invention

[0005] The purpose of the present invention is to provide a new deep-water jacket and installation method for offshore wind power systems, so as to solve the problem of the jacket being prone to tilting due to geological conditions, which will change the center of gravity of the jacket and reduce its stability on the seabed.

[0017] A new deepwater jacket installation method for an offshore wind power system comprises the following steps:

[0018] Step 1, assemble the catheter frame, pre-connect the second catheter frame with the first catheter frame through the second plug-in rod and the first plug-in groove, and then use the second connecting mechanism to connect them. During the plug-in process, the second mounting sleeve moves with the fixing rod, causing the second limit rod to be inserted into the groove at the top of the mounting seat, and the limit head is ready to be inserted into the interior 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, driving the first limit rod to move in the limit hole, and moving the lifting sleeve downward. When the limit head is inserted into the bottom end of the locking ring, the elastic second limit rod begins to recover, so that the limit head clamps the locking ring, completing the locking of the second mounting sleeve and the second limit rod by the mounting seat.

[0020] Step three, strengthen the connection. The fixed rod drives the first installation sleeve to move so that the second plug-in slot at the bottom is plugged into the third plug-in rod. The second oil cylinder drive block moves, and the inclined surface pushes the lifting rod to move upward, so that the limit frame applies pressure to the limit plate to complete the connection between the first installation sleeve and the fixed 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 guide frame and the second guide frame are skewed as a whole, the adjustment mechanism can be used to adjust them. The first oil cylinder controls the movement of the linkage rod, which causes the two transmission rods to move and transmit the force to the third rotating frame. Through the coordinated action of the three swing rods and the cooperation of the first rotating frame and the second rotating frame, the angle of the first guide frame is effectively adjusted.

[0022] Step 5: Adaptive anchoring. Adjust the anchoring depth and angle of the plug-in rod according to the seabed topography and geological conditions. Drive the threaded rod to rotate through the second waterproof motor. The lifting plate drives the sliding rod to push the plug-in rod to the specified position. At the same time, the first waterproof motor drives the worm to rotate to accurately adjust the anchoring angle of the plug-in rod.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, by combining sensor technology and mechanical adjustment mechanism, adaptive adjustment and stable monitoring of submarine structures are realized to predict potential risks and ensure the safety and stability of the system. Through the coordinated work of multiple linkage parts, precise adjustment of the conductor frame is realized. The activation of the first oil cylinder causes the linkage rod to move, and the force is transmitted to the third rotating frame through the transmission rod, and then acts on the swing rod to coordinately adjust the angle of the conductor frame, so as to maintain the stability of the overall structure. In addition, according to the seabed topography and geological conditions, the anchoring depth and angle of the plug-in rod are adjusted, and the threaded rod is driven to rotate by the second waterproof motor, and the lifting plate moves to drive the sliding rod to push the plug-in rod to the specified position. At the same time, the first waterproof motor drives the worm to rotate to accurately adjust the anchoring angle of the plug-in rod, which not only improves the reliability and stability of the anchoring, but also ensures the flexibility and adaptability of the system in a complex seabed environment.

[0025] 2. In the present invention, in the process of connecting the second catheter frame and the first catheter frame, a second connecting mechanism is used to ensure the stability and firmness of the connection. The connection process first starts with the plugging of the second plug-in rod with the first plug-in groove. Along with the movement of the fixing rod, the movement of the second mounting sleeve prompts the second limiting rod to be smoothly inserted into the groove of the mounting seat. At the same time, the limiting head is ready to be inserted into the locking ring to prepare for subsequent locking. When the second mounting sleeve is plugged into the top of the mounting seat, the limiting head is not completely engaged with the locking ring. At this time, the operator can further promote the connection process by rotating the second threaded rod. The rotation of the threaded rod effectively controls its position and pushes the lifting sleeve to move. The movement of the lifting sleeve guides the first limiting rod to move in the limiting hole and prompts it to move vertically downward. Finally, the limiting head is inserted into the bottom end of the locking ring, and the elastic second limiting rod returns to its original position and clamps the locking ring, thereby completing a firm connection. The 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 the connection tightness to be fine-tuned according to environmental requirements, ensuring adaptability and safety under various usage conditions.

[0026] 3. In the present invention, through the efficient operation of the second connecting mechanism, the movement of the fixing rod drives the first installation sleeve to smoothly connect with the third plug-in rod. After the connection is completed, the second oil cylinder driving block is started to move, the lifting rod is pushed upward, and a force is applied to the limit frame to make it start to rotate. One end of the limit frame presses the limit plate to lock the limit plate, thereby completing the connection between the first installation sleeve and the fixing block. This connection process significantly enhances the stability between the second conductor frame and the first conductor frame. In the overall structure, the first connecting mechanism is responsible for locking the second conductor frame, while the second connecting mechanism realizes the locking of the second conductor frame to the first conductor frame, forming a two-way locking mechanism, which 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 convenience 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 installation sleeve and the fixing block improves the seismic resistance and durability of the overall structure while ensuring strength. In extreme submarine environments and complex working conditions, the two-way locking mechanism ensures a stable connection between the second conductor frame and the first conductor frame, providing a strong guarantee for the long-term stable operation of the system.

[0038] The anchor mechanism 2 includes a first mounting frame 21, a first fixing frame 211 is fixedly connected to the center of one side of the first mounting frame 21, both sides of the first fixing frame 211 are rotatably connected to mounting shells 231, the mounting shells 231 are fixedly connected to the side walls of the first mounting frame 21, a worm 28 is rotatably connected to the inner side of the first fixing frame 211, both sides of the worm 28 are meshedly connected to worm wheels 29, the worm wheels 29 are fixedly connected to the side walls 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, and a first plug-in rod 25 is fixedly connected to the bottom of the lifting plate 24;

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

[0040] In this embodiment, during the installation process, it is first necessary to install sensors on the base 1 and the first conductor frame 4 to monitor the structural state and environmental parameters in real time. The sensors can collect data and predict potential risks through data analysis to ensure the safety and stability of the operation of the entire system. When the first conductor frame 4 and the second conductor frame 5 are skewed as a whole, they can be adjusted by the adjustment mechanism 3. The adjustment process is completed by the coordinated action of multiple mechanisms. First, the activity of the linkage rod 37 is controlled by starting the first oil cylinder 31. With the action of the linkage rod 37, the force will be transmitted through the transmission rod 36, and the activity of the two transmission rods 36 will further transmit the force to the third rotating frame 35. At this time, the third rotating frame 35 will then transmit 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 will also work together, so that the entire adjustment process proceeds smoothly. This series of actions can eventually change the angle of the first conductor frame 4, ensuring that the angle of the first conductor frame 4 and the second conductor frame 5 can be adjusted at any time, realizing adaptive adjustment, thereby ensuring the overall stability of the structure.

[0041] In addition, according to the topography and geological conditions of the seabed, the system can further adjust the anchoring depth and angle of the first plug-in rod 25. When adjusting the depth, the first threaded rod 23 is driven to rotate by the second waterproof motor 232, and the first threaded rod 23 controls the lifting and lowering movement of the lifting plate 24. During the movement of the lifting plate 24, it will drive the sliding rod 26 to move together, thereby pushing the first plug-in rod 25 to be inserted into the specified anchoring position. In order to ensure the accuracy of the anchoring angle, the system can use the first waterproof motor 22 to drive the rotation of the worm 28. The rotation of the worm 28 will apply force to the two worm gears 29 at the same time, and the rotation of the worm gear 29 can drive the two mounting shells 231 to rotate respectively, thereby accurately adjusting the anchoring angle of the first plug-in rod 25. This design allows adaptive angle adjustment according to different geological conditions, thereby improving the reliability and stability of anchoring.

[0042] Combining sensor technology and mechanical adjustment mechanisms, it can automatically adjust the state of the structure according to real-time monitoring data, which not only ensures the stability of the device, but also provides flexibility and precision to adapt to complex seabed environments. By precisely controlling the depth and angle of anchoring, the system can ensure stable and reliable support under various geological conditions.

[0043] Embodiment 2: Figure 6 As shown, the second connection mechanism 7 includes a mounting seat 75 and a second mounting sleeve 71. The side wall of the second mounting sleeve 71 is fixedly connected to the fixed rod 51. The bottom of the mounting seat 75 is fixedly connected to the top of the first pipe frame 4. A locking ring 76 is fixedly connected to the inner side of the top of the mounting seat 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 clamped with the locking ring 76. The top side wall of the lifting sleeve 74 is fixedly connected to the first limiting rod 741. Limiting holes 711 are provided on both sides of the second mounting sleeve 71. The limiting holes 711 are slidably connected to the first limiting rod 741. The top of the second mounting sleeve 71 is symmetrically fixedly connected to the mounting blocks 72. The inner sides of the two mounting blocks 72 are rotatably connected to the second threaded rods 73. The bottom end of the second threaded rod 73 is rotatably connected to the top of the lifting sleeve 74. The outer surface of the top of the second threaded rod 73 is threadedly connected to the rotating sleeve 731.

[0044] In this embodiment, in the process of connecting the second conduit frame 5 and the first conduit frame 4, the second connecting mechanism 7 is used to ensure the stable connection between the two. First, the connection process starts with the plugging of the second plugging rod 52 and the first plugging groove 41. During the plugging process, the second mounting sleeve 71 will move with the movement of the fixing rod 51, so that the second limiting rod 77 can also be smoothly inserted into the groove at the top of the mounting seat 75. At the same time, the limiting head 771 will also be ready to be inserted into the inner side of the locking ring 76 to prepare for subsequent locking.

[0045] When the second mounting sleeve 71 is plugged into the top of the mounting seat 75, the stopper 771 at the bottom of the second stopper rod 77 is not completely plugged into the locking ring 76. At this time, the operator can start to rotate the second threaded rod 73 to further promote the connection process. During the rotation process, 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. At the same time, in order to facilitate operation, the second threaded rod 73 can be equipped with a mounting handle so that the operator can operate more easily.

[0046] The movement of the lifting sleeve 74 guides the first limiting rod 741 to move inside the limiting hole 711, and causes the lifting sleeve 74 to move downward in the vertical direction. As the limiting head 771 continues to move downward, it will eventually insert into the bottom end of the locking ring 76. When the limiting head 771 is successfully inserted, the elastic second limiting rod 77 begins to return to its original position. At this time, the limiting head 771 will clamp the locking ring 76, thereby completing the locking of the second mounting sleeve 71 and the second limiting rod 77 by the mounting seat 75.

[0047] Through this series of connection steps, a firm and stable connection between the second conductor frame 5 and the first conductor frame 4 is ensured. This design not only improves the convenience of the connection process, but also enhances the overall strength and safety of the structure after connection. In addition, the design of the threaded rod and the lifting sleeve 74 makes the connection process have a certain degree of adjustability, and the tightness of the connection can be fine-tuned as needed to meet the needs of different environments and use conditions. Overall, the connection mechanism shows good functionality and practicality, ensuring the stability and safety of the system during operation.

[0048] Embodiment 3: According to Figure 7-8 As shown, the first connecting mechanism 6 includes a fixed block 62 and a first mounting sleeve 61. The bottom of the fixed block 62 is fixedly connected to the top of the first guide tube frame 4, and the side wall of the first mounting sleeve 61 is fixedly connected to the fixed rod 51. The inner side of the fixed block 62 is slidably connected to a driving block 64, and an inclined surface 641 is provided at one end of the driving block 64. A fixed column 67 is fixedly connected to the center of the top of the fixed block 62, and a lifting rod 65 is slidably connected to the inner side of the fixed column 67. The bottom end of the lifting rod 65 and the inner side of the inclined surface 641, and both sides of the fixed column 67 are rotatably connected to the limiting frame 66. A second plug-in slot 611 is provided at the bottom end of the first mounting sleeve 61, and two third plug-in rods 621 are symmetrically fixedly connected to the top of the fixed block 62. The third plug-in rods 621 are plugged into the second plug-in slot 611. A limiting plate 612 is fixedly connected to the inner side of the first mounting sleeve 61, and the limiting frame 66 is clamped with the limiting plate 612. A second oil cylinder 63 is fixedly connected to the side wall of the fixed block 62, and an output end of the second oil cylinder 63 is fixedly connected to the driving block 64. One end of the limiting frame 66 is located on the inner side of the lifting rod 65.

[0049] In this embodiment, through the effective operation of the second connection mechanism 7, the fixing rod 51 drives the first installation sleeve 61 to move together, so that the second plug-in groove 611 at the bottom of the first installation sleeve 61 can be smoothly plugged with the third plug-in rod 621. After the plug-in is completed, the driving block 64 can be driven to move by starting the second oil cylinder 63. The inclined surface 641 of the driving block 64 is designed to effectively promote the movement of the lifting rod 65.

[0050] During the movement of the lifting rod 65, it not only moves upward under the push of the driving block 64, but also exerts a force on the limiting frame 66, prompting the limiting frame 66 to start rotating. One end of the limiting frame 66 will exert a pressing effect on the limiting plate 612 after rotating, so that the limiting plate 612 can be locked, thereby completing the connection between the first installation sleeve 61 and the fixing block 62. This connection process plays an important role in strengthening the connection between the second pipe frame 5 and the first pipe frame 4, and also significantly improves the firmness of the connection.

[0051] In the overall structure, the first connection mechanism 6 is responsible for locking the second conductor frame 5 through the first conductor frame 4, while the second connection mechanism 7 is responsible for locking the first conductor frame 4 by the second conductor frame 5. This two-way locking mechanism can further enhance the stability of the connection and ensure the reliability of the structure in various operating environments. In addition, the two-way locking design also improves the convenience of operation, making the connection and disassembly process more efficient, saving time and labor costs.

[0052] Through this design, the connection between the first mounting sleeve 61 and the fixing block 62 not only ensures the strength of the connection, but also improves the seismic resistance and durability of the overall structure. Whether in extreme submarine environments or under complex working conditions, the two-way locking mechanism can ensure that the connection between the second jacket 5 and the first jacket 4 is stable and unchanged, providing a guarantee for the long-term stable operation of the system.

[0053] Embodiment 4: A new deepwater jacket installation method for an offshore wind power system comprises the following steps:

[0054] 1) Assemble the catheter frame, pre-connect the second catheter frame 5 and the first catheter frame 4 through the second plug-in rod 52 and the first plug-in groove 41, and then use the second connecting mechanism 7 to connect them. During the plug-in process, the second mounting sleeve 71 moves with the fixing rod 51, causing the second limiting rod 77 to be inserted into the groove at the top of the mounting seat 75, and the limiting head 771 is ready to be inserted into the interior of the locking ring 76.

[0055] 2) Adjust the connection position, rotate the second threaded rod 73 to adjust its position, thereby pushing the lifting sleeve 74 to move, driving the first limiting rod 741 to move in the limiting hole 711, and moving the lifting sleeve 74 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 clamps the locking ring 76, completing the locking of the second mounting sleeve 71 and the second limiting rod 77 by the mounting seat 75.

[0056] 3) Strengthen the connection. The fixing rod 51 drives the first installation sleeve 61 to move, so that the second plug-in groove 611 at the bottom is plugged into the third plug-in rod 621. The second oil cylinder 63 drives the 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 installation sleeve 61 and the fixing block 62.

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

[0058] 5) Adaptive anchoring: adjust the anchoring depth and angle of the plug-in rod according to the seabed topography and geological conditions. The threaded rod is driven to rotate by the second waterproof motor 232, and the lifting plate 24 drives the sliding rod 26 to push the plug-in rod to the specified position. At the same time, the first waterproof motor 22 drives the worm 28 to rotate to accurately adjust the anchoring angle of the plug-in rod.

[0059] The use method and working principle of the device: During the installation process, first assemble the second conduit frame 5 and the first conduit frame 4. When connecting the second conduit frame 5 and the first conduit frame 4, use the second connecting mechanism 7. The connection process first involves plugging the second plug-in rod 52 into the first plug-in slot 41. During the plug-in 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 seat 75, and the limiting head 771 is ready to be inserted into the interior of the locking ring 76. As the second mounting sleeve 71 is plugged into the top of the mounting seat 75, the limiting head 771 is not completely plugged into the locking ring 76. At this time, the second threaded rod 73 can be rotated, and its rotation is used to adjust the position of the second threaded rod 73, so as to push the lifting sleeve 74 to move, drive the first limiting rod 741 to move inside the limiting hole 711, and then move the lifting sleeve 74 downward. After 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 clamps the locking ring 76 , thereby completing the locking of the second mounting sleeve 71 and the second limiting rod 77 by the mounting seat 75 .

[0060] While the fixing is completed by the second connecting mechanism 7, the fixing rod 51 also drives the first installation sleeve 61 to move, so that the second plug-in groove 611 at the bottom thereof is plugged into the third plug-in rod 621. Subsequently, the driving of 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. 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 limit frame 66, causing the limit frame 66 to start rotating. After the limit frame 66 rotates, one end applies pressure to the limit plate 612 to lock the limit plate 612, completing the connection between the first installation sleeve 61 and the fixing block 62, thereby reinforcing the connection between the second guide tube frame 5 and the first guide tube frame 4 and improving the firmness of the connection.

[0061] The first connection mechanism 6 locks the second catheter frame 5 through the first catheter frame 4, and the second connection mechanism 7 locks the first catheter frame 4 through the second catheter frame 5. The two-way locking design further enhances the stability of the connection and improves the convenience of operation.

[0062] First, sensors are installed on the base 1 and the first conductor frame 4 to monitor the structural status and environmental parameters in real time, and predict potential risks through data analysis. If the first conductor frame 4 and the second conductor frame 5 are skewed as a whole, the adjustment mechanism 3 can be used to adjust them. During the adjustment process, the movement of the linkage rod 37 is controlled by the first oil cylinder 31. When the linkage rod 37 starts to move, the force is transmitted to the transmission rod 36, which promotes the movement of the two transmission rods 36, thereby transmitting the force to the third rotating frame 35. At this time, the third rotating frame 35 transmits the 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 conductor frame 4 can be effectively adjusted, so as to adjust the relative angle between the first conductor frame 4 and the second conductor frame 5 at any time to ensure the overall stability.

[0063] In addition, the anchoring depth and angle of the first plug-in rod 25 can also 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, so that the first plug-in rod 25 is plugged in. When adjusting the angle, the first waterproof motor 22 drives the worm 28 to rotate, and the worm 28 applies a force to the two worm wheels 29, so that the two worm wheels 29 respectively drive the two mounting shells 231 to rotate when rotating, thereby controlling the angle of the first plug-in rod 25 during the anchoring process, and realizing 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 in the protection scope of the present invention.
