[0048] In related technologies, with the sustainable development of green energy, the deep sea has rich wind energy resources, and deep sea wind power generation is receiving more and more attention and attention.

[0049] Deep-sea wind power generation typically involves installing deep-sea wind turbines on a wind platform. These platforms are often semi-submersible and typically have a three- or four-column structure.

[0050] Reference Figure 1 As shown, taking a three-column wind turbine platform as an example, the wind turbine platform 100 is supported by three columns 110, with two columns 110 fixedly connected by connecting rods. The three columns 110 and the connecting rods form a triangular structure to enhance the stability of the wind turbine platform 100. A heave tank 130 is located beneath each column 110, and the heave tanks 130 of two columns 110 are fixedly connected by a lower pontoon 140. The wind turbine platform 100 is also equipped with diagonal braces 150, which are fixedly connected to the crossbars 120 and the lower pontoon 140. The diagonal braces 150 are arranged at an angle to enhance the strength of the wind turbine platform 100.

[0051] After launching, the wind turbine platform 100 docks at the pier, where the wind turbine generator set (such as the tower, main engine, blades, and other equipment) is installed. While docked, the wind turbine platform 100 will float with the waves. To prevent the wind turbine platform 100 from colliding with the pier and causing damage, a semi-submersible barge is placed between the wind turbine platform 100 and the pier, with airbags installed on both sides of the semi-submersible barge.

[0052] However, the wind turbine platform 100 and the semi-submersible barge independently respond to wave motion, causing their relative position to change. This can cause the heave tank 130 and other external equipment on the wind turbine platform 100 to collide with the semi-submersible barge or the dock, resulting in damage to the heave tank 130 and other external equipment. Therefore, existing mooring systems cannot guarantee the safety of wind turbine platforms when moored.

[0053] In order to solve the above problems, the berthing device provided in the present application is fixed to the wind turbine platform by a fixing part, which can prevent the berthing device from generating friction or collision with the wind turbine platform. The two ends of the shock-absorbing mechanism are fixedly connected to the fixing part and the buffer part respectively. When the buffer part collides with the dock, the buffer part deforms to absorb part of the energy generated by the collision, and the shock-absorbing mechanism can absorb the energy generated by the collision that is not absorbed by the buffer part. The deformation of the buffer part reduces the intensity during the energy transfer process, so that the shock-absorbing mechanism can absorb and consume part or all of the remaining energy generated by the collision. The berthing device can reduce the collision energy between the wind turbine platform and the dock, thereby improving the safety of the wind turbine platform and extending the service life of the wind turbine platform.

[0054] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] Reference Figure 2 As shown, the mooring device 300 provided in this application is used to dock a wind turbine platform 100 at a pier 200, ensuring the safety and stability of the wind turbine platform 100 and facilitating wind turbine installation. Waves, through wave force, can cause the wind turbine platform 100 to collide with the pier 200. The mooring device 300 can prevent damage to the wind turbine platform 100 caused by the forces generated by the collision. The mooring device 300 can also be used to prevent collisions with other structures, such as marine aquaculture facilities, drilling platforms, floating docks, and other facilities.

[0056] Reference Figure 2 and Figure 3As shown, the docking device 300 includes a fixing member 320 , which is used to fix other mechanisms to the wind turbine platform 100 .

[0057] In some possible implementations, the fixing member 320 is configured as a metal enclosure, which can be disposed around the outside of the column 110 of the wind turbine platform 100. The metal enclosure can be fixed to the wind turbine platform 100 via cables.

[0058] The inner surface of the metal enclosure may be provided with a corrugated structure to increase the friction between the metal enclosure and the column 110 , thereby preventing the metal enclosure from sliding, and further improving the stability of the connection between the metal enclosure and the column 110 .

[0059] In some possible implementations, the fixing member 320 is configured as a clamp, which is disposed on the column 110 of the wind turbine platform 100. The clamp is easy to install and remove, which facilitates the installation and removal of the docking device 300 and reduces operation time.

[0060] The berthing device 300 includes a shock absorbing mechanism 310 , which is used to absorb the collision force between the wind turbine platform 100 and the pier 200 to ensure the safety of the wind turbine platform 100 .

[0061] One end of the shock absorbing mechanism 310 is fixedly connected to the fixing member 320. In other words, the shock absorbing mechanism 310 is fixed to the wind turbine platform 100 via the fixing member 320, which prevents the shock absorbing mechanism 310 and the wind turbine platform 100 from moving independently due to the influence of waves, thereby preventing the shock absorbing mechanism 310 and the wind turbine platform 100 from displacement, and further preventing friction or collision between the shock absorbing mechanism 310 and the wind turbine platform 100.

[0062] In some possible implementations, the shock absorbing mechanism 310 is configured as a hydraulic damper. The hydraulic damper is filled with hydraulic oil, and the flow of the hydraulic oil absorbs and alleviates the force generated by the collision.

[0063] In some possible embodiments, the shock absorbing mechanism 310 can also be configured as a magnetorheological damper. By controlling the current intensity, the magnetic field intensity applied to the magnetorheological fluid can be adjusted, thereby affecting its state and corresponding damping force to absorb and alleviate the force generated by the collision.

[0064] The shock absorbing mechanism 310 and the fixing member 320 may be connected by welding.

[0065] Multiple damping mechanisms 310 can be provided, with each mechanism 310 spaced apart. Each damping mechanism 310 is connected to a fixing member 320 . When the wind turbine platform 100 is subjected to a collision, each damping mechanism 310 can share the force, preventing deformation or damage to the wind turbine platform 100 caused by excessive local force.

[0066] In addition, multiple shock absorbing mechanisms 310 are provided at multiple different directions of the wind turbine platform 100 to absorb and buffer the forces generated by collisions in multiple directions.

[0067] The docking device 300 includes a buffer member 330 . The buffer member 330 converts the energy generated by the impact into its own deformation energy through plastic deformation of the material, thereby reducing the force transmitted to the shock absorbing mechanism 310 and the wind turbine platform 100 .

[0068] The first end of the buffer member 330 is fixedly connected to the other end of the shock absorbing mechanism 310. In other words, the fixing member 320, the shock absorbing mechanism 310 and the buffer member 330 are arranged in sequence.

[0069] In some possible implementations, the buffer member 330 can be configured as a shock-absorbing block made of polyurethane to reduce the collision force between the buffer member 330 and the dock 200. The buffer member 330 can reduce the transmission of the collision force to the shock-absorbing mechanism 310 and the wind turbine platform 100, thereby preventing the buffer member 330 from colliding with the dock 200 and causing damage to the shock-absorbing mechanism 310 or the wind turbine platform 100.

[0070] In some possible implementations, the buffer member 330 is configured as a rubber shock-absorbing block. Rubber material has high elasticity and deformation capacity, and can absorb and consume the energy generated by the collision between the wind turbine platform 100 and the dock 200, thereby reducing the force applied to the wind turbine platform 100 and thus reducing damage to the wind turbine platform 100.

[0071] The rubber damping block and the damping mechanism 310 may be connected by a vulcanization process.

[0072] The rubber damping block is also durable. In addition, the rubber damping block has good weather resistance and corrosion resistance and can be used for a long time in a marine environment. This can improve the service life of the mooring device 300.

[0073] Furthermore, the cushioning member 330 is provided with a cavity 331 extending along its length. When the cushioning member 330 is impacted, part of its material deforms toward the cavity 331, thereby absorbing and dissipating the energy generated by the collision. Furthermore, the cavity 331 reduces the amplitude of the cyclic stresses in the cushioning member 330, thereby reducing fatigue damage to the cushioning member 330.

[0074] Accordingly, a plurality of buffer members 330 may be provided, and the buffer members 330 are provided corresponding to the shock absorbing mechanisms 310 .

[0075] The berthing device 300 is fixed to the wind turbine platform 100 by the fixing member 320, which can prevent the berthing device 300 from causing friction or collision with the wind turbine platform 100. The two ends of the shock absorbing mechanism 310 are fixedly connected to the fixing member 320 and the buffer member 330 respectively. When the buffer member 330 collides with the dock 200, the buffer member 330 deforms to absorb part of the energy generated by the collision, and the shock absorbing mechanism 310 can absorb the energy generated by the collision that is not absorbed by the buffer member 330. The deformation of the buffer member 330 reduces the intensity during the energy transfer process, allowing the shock absorbing mechanism 310 to absorb and consume part or all of the remaining energy generated by the collision. The berthing device 300 can reduce the collision energy between the wind turbine platform 100 and the dock 200, thereby improving the safety of the wind turbine platform 100 and extending the service life of the wind turbine platform 100.

[0076] The structure of the shock absorbing mechanism is introduced in detail below.

[0077] Reference Figure 4 and Figure 5 As shown, the shock absorbing mechanism 310 includes a mounting shell 311 , which is the outer shell of the shock absorbing mechanism 310 and can protect the parts inside the mounting shell 311 , thereby preventing the parts inside the mounting shell 311 from being physically damaged.

[0078] For example, the installation shell 311 can be made of steel, and the outer surface of the installation shell 311 is coated with anti-corrosion material to ensure the reliability of the installation shell 311.

[0079] In addition, the upper surface of the installation shell 311 can be used as a boarding passage for workers from the dock 200 to the wind turbine platform 100 .

[0080] In some possible implementations, handrails are provided on the installation shell 311 to facilitate the passage of workers.

[0081] The shock absorbing mechanism 310 includes an elastic member 312. The elastic member 312 absorbs and consumes collision energy through elastic deformation, and slowly releases the energy through elastic restoring force after the collision, thereby reducing the collision force transmitted to the wind turbine platform 100 and improving the stability of the wind turbine platform 100.

[0082] For example, the elastic member 312 may be configured as an air spring, which absorbs and consumes the energy generated by the collision through the compression of air.

[0083] The elastic member 312 is disposed in the mounting shell 311 , and one end of the elastic member 312 is fixedly connected to one end of the mounting shell 311 , thereby preventing the elastic member 312 from moving during a collision and preventing the shock absorbing mechanism 310 from losing its function.

[0084] For example, the mounting shell 311 is provided with a mounting groove, and one end of the elastic member 312 is inserted into the mounting groove, thereby limiting the movement of the elastic member 312 .

[0085] For another example, the elastic member 312 and the mounting shell 311 may be connected by welding to ensure the stability of the connection between the elastic member 312 and the mounting shell 311 .

[0086] In some possible implementations, the elastic member 312 is configured as a spring, and the energy generated by the collision is absorbed and released through the expansion and contraction of the spring.

[0087] Furthermore, the mounting shell 311 is provided with a support rod, and the spring is sleeved on the outer periphery of the support rod. The support rod can prevent the spring from bending laterally during compression or extension, thereby ensuring the stability and effectiveness of the spring.

[0088] In some possible implementations, multiple elastic members 312 are provided, and the multiple elastic members 312 are arranged in an array. Through the coordinated operation of the multiple elastic members 312, the shock absorbing mechanism 310 can absorb and dissipate more collision energy, thereby reducing the force transmitted to the wind turbine platform 100 and improving the safety of the wind turbine platform 100.

[0089] Furthermore, the array arrangement of the plurality of elastic members 312 can improve the uniformity of load distribution, reduce the stress on a single elastic member 312, and reduce local stress concentration, thereby extending the service life of the elastic members 312. Adjacent elastic members 312 within the plurality of elastic members 312 are spaced apart to ensure that each elastic member 312 can expand and contract and to prevent interference with adjacent elastic members 312.

[0090] For example, the plurality of elastic members 312 are arranged in two rows and twelve columns, providing multi-point support for the shock absorbing mechanism 310 , thereby enhancing the stability and anti-deformation capability of the shock absorbing mechanism 310 .

[0091] The elastic member 312 expands and contracts in the direction from the fixing member 320 to the buffer member 330. When the buffer member 330 is hit, the elastic member 312 is compressed to buffer and absorb the energy transmitted by the buffer member 330 to ensure that less energy is transmitted to the fixing member 320, thereby preventing the wind turbine platform 100 from being damaged.

[0092] Shock absorber mechanism 310 includes a movable member 313. Movable member 313 is fixedly connected to the other end of elastic member 312 and moves as elastic member 312 expands and contracts. Movable member 313 serves as an intermediate transmission component, transferring energy from buffer member 330 to elastic member 312, causing elastic member 312 to expand and contract to cushion and absorb energy. Alternatively, movable member 313 can be fixedly connected to the other end of elastic member 312 by welding or gluing.

[0093] The movable part 313 can be made of metal material to ensure the reliability and durability of the movable part 313 .

[0094] For example, the movable member 313 is provided with a mounting groove, and the other end of the elastic member 312 is inserted into the mounting groove, thereby limiting the movement of the elastic member 312 .

[0095] In some possible embodiments, a portion of the movable member 313 extends out of the mounting housing 311, while a portion of the movable member 313 is fixedly connected to the buffer member 330. In other words, the end of the elastic member 312 connected to the movable member 313 is free. When the buffer member 330 collides with the dock 200, the end of the elastic member 312 connected to the movable member 313 moves relative to the end of the elastic member 312 connected to the fixed member 320. This allows the elastic member 312 to absorb the energy generated by the collision, ensuring the safety of the wind turbine platform 100.

[0096] In some possible embodiments, a portion of the movable member 313 extends out of the mounting housing 311, while a portion of the movable member 313 is fixedly connected to the fixed member 320. In other words, the end of the elastic member 312 connected to the movable member 313 is fixed. When the buffer member 330 is impacted, the end of the elastic member 312 connected to the buffer member 330 moves relative to the end of the elastic member 312 connected to the movable member 313. This allows the elastic member 312 to absorb the energy generated by the collision, ensuring the safety of the wind turbine platform 100.

[0097] Furthermore, the movable member 313 includes a limiting plate 313 a and a plurality of connecting portions 313 b . One side of the limiting plate 313 a is fixedly connected to the elastic member 312 , so that the expansion and contraction of the elastic member 312 can be transmitted to other positions.

[0098] When the shock absorbing mechanism 310 is provided with multiple elastic members 312 , the limiting plate 313 a is fixedly connected to the multiple elastic members 312 , and the limiting plate 313 a can disperse the collision energy to the multiple elastic members 312 to prevent a single elastic member 312 from being subjected to stress.

[0099] The limiting plate 313 a may be configured as a metal plate to ensure uniform connection between the limiting plate 313 a and the plurality of elastic members 312 .

[0100] The movable member 313 includes a plurality of connecting portions 313b, which are fixedly connected to the other side of the limiting plate 313a. The plurality of connecting portions 313b and the limiting plate 313a can be formed by integral molding or welding.

[0101] When the buffer 330 collides with the dock 200, the multiple connecting parts 313b are fixedly connected to the buffer 330 to withstand the impact force transmitted by the buffer 330. The multiple connecting parts 313b transmit the impact force to the elastic member 312 connected to the limiting plate 313a.

[0102] The plurality of connection portions 313 b are arranged at intervals, which can reduce the amount of material used in the movable member 313 , thereby reducing the processing and manufacturing costs of the movable member 313 .

[0103] The multiple connection parts 313b can be used as connection parts to transmit collision force. The multiple connection parts 313b can also be used for boarding channels, which can improve the multifunctionality of the movable part 313 and thus improve the space utilization of the docking device 300.

[0104] Specifically, the cross-sectional shape of the connection portion 313b can be set to a rectangle, an inverted triangle, or the like.

[0105] Continue to refer to Figure 4 and Figure 5 As shown, the docking device 300 includes a plurality of support plates 340. Each support plate 340 is spaced apart, which can reduce the material usage of the docking device 300, thereby reducing the processing and manufacturing costs of the docking device 300. The first ends of the support plates 340 are connected to the fixing member 320, and the second ends of the support plates 340 are connected to the shock absorbing mechanism 310. The support plates 340 facilitate the connection between the fixing member 320 and the shock absorbing mechanism 310.

[0106] The support plate 340 , the fixing member 320 and the shock absorbing mechanism 310 may be connected by welding to enhance the reliability of the connection.

[0107] Each support plate 340 can serve as a connecting structure between the fixing member 320 and the shock absorbing mechanism 310 , and each support plate 340 can also be used as a boarding passage, thereby improving the versatility of the support plate 340 and improving the space utilization of the berthing device 300 .

[0108] Specifically, the cross-sectional shape of the support plate 340 can be set to a rectangle, an inverted triangle, or the like.

[0109] Combine Figure 4 and Figure 5 , refer to Figure 6 As shown, the mounting shell 311 is provided with an opening 3113, and the opening 3113 faces the buffer member 330. A plurality of connecting portions 313b extend out of the opening 3113 to facilitate the movement of the movable member 313 along with the expansion and contraction of the elastic member 312.

[0110] The mounting housing 311 is provided with limiting portions 3114, which are positioned on either side of the opening 3113. The limiting portions 3114 extend perpendicularly from the first end of the mounting housing 311 to the second end of the mounting housing 311. Limiting plates 313a abut against the limiting portions 3114 to restrict the position of the limiting plates 313a, preventing the movable member 313 from escaping from the mounting housing 311 through the opening 3113. This prevents the movable member 313 from causing excessive stretching of the elastic member 312 connected thereto, thereby ensuring the reliability of the elastic member 312.

[0111] A guide rod 3111 is provided within the mounting housing 311 to guide the movable member 313. The guide rod 3111 is fixedly connected to the mounting housing 311. For example, both ends of the guide rod 3111 and the mounting housing 311 may be connected by welding to ensure a secure connection between the guide rod 3111 and the mounting housing 311.

[0112] In addition, the guide rod 3111 is fixedly connected to the mounting shell 311 , and the guide rod 3111 can improve the strength of the mounting shell 311 .

[0113] The movable member 313 is provided with a mounting hole 3131, which is provided in conjunction with the guide rod 3111. The axial direction of the guide rod 3111 is the same as the expansion and contraction direction of the elastic member 312. In other words, the movable member 313 is sleeved on the guide rod 3111 through the mounting hole 3131, and the movable member 313 moves along the axial direction of the guide rod 3111. The expansion and contraction direction of the movable member 313 is the same as that of the elastic member 312. In this way, the force generated by the elastic member 312 during expansion and contraction can push or pull the movable member 313 to move along the guide rod 3111, thereby reducing the lateral force generated during the expansion and contraction of the elastic member 312, reducing the probability of wear and damage to the elastic member 312, and improving the reliability and service life of the docking device 300.

[0114] Multiple guide rods 3111 can be set, and multiple guide rods 3111 can constrain the movable part 313 from multiple directions, reducing the shaking, deviation and swinging of the movable part 313 during the movement, so that the movable part 313 can move in a certain direction, thereby improving the stability and reliability of the movement of the docking device 300.

[0115] The guide rod 3111 may be disposed near an inner wall of the mounting shell 311 to improve space utilization within the mounting shell 311 .

[0116] Combine Figure 4 and Figure 5 , refer to Figure 7As shown, one of the mounting housing 311 and the movable member 313 is provided with a limit rod 3112, and the other of the mounting housing 311 and the movable member 313 is provided with a limit sleeve 3132. The limit sleeve 3132 is sleeved on the limit rod 3112. The inner diameter of the limit sleeve 3132 matches the diameter of the limit rod 3112. The longer of the limit rod 3112 and the limit sleeve 3132 can limit the compression length of the elastic member 312.

[0117] The limiting rod 3112 and limiting sleeve 3132 limit the extreme positions of the mounting housing 311 and the movable member 313, thereby limiting further compression of the elastic member 312. Excessive compression can cause elastic failure, deformation, or even breakage of the elastic member 312, impacting the performance and service life of the docking device 300. By limiting the compressed length of the elastic member 312 using the limiting rod 3112 or limiting sleeve 3132, the elastic member 312 can be ensured to operate within a safe compression range, improving the reliability and stability of the docking device 300.

[0118] In addition, the limiting rod 3112 and the limiting sleeve 3132 have a simple structure and are easy to install and disassemble, which facilitates the maintenance and repair of the docking device 300.

[0119] For example, the mounting housing 311 is provided with a limit rod 3112, and the movable member 313 is provided with a limit sleeve 3132, which is sleeved on the limit rod 3112. When the limit rod 3112 is long, the end surface of the free end of the limit rod 3112 abuts against the movable member 313. In this case, the length of the limit rod 3112 determines the compression length of the elastic member 312, thereby preventing the elastic member 312 from being overcompressed and causing elastic failure of the elastic member 312.
