Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a roll-damping fin assembly of a linked seakeeping running mechanism, an amphibious vessel, and its operating method. Background Technology

[0002] my country has numerous islands, and communication and connections between them are becoming increasingly close. Passenger demand on many shipping routes is constantly increasing. To meet this demand, inter-island transport vessels have begun to enter the market. However, existing transport vessels suffer from poor seakeeping, are prone to rough terrain, and have low operational rates, making them unsuitable for routine transport needs. Furthermore, some transport vessels are equipped with anti-roll propellers on their tracked systems, but the anti-roll effect is poor and they lack protection, making them easily damaged. Therefore, we need to research and design new types of transport vessels with active anti-roll and shock absorption functions, suitable for various sea and road conditions, to improve passenger comfort and reliability.

[0003] For example, Chinese patent CN206633740 discloses a new type of tracked amphibious tidal flat vessel: including a hull (1), characterized in that: a cabin (2) is opened at the upper end of the hull (1), track wheels (3) are provided on the front and rear sides of the lower end of the hull (1), a power shaft (10) is provided at the left end between the track wheels (3), baffles (4) are provided at the front and rear ends of the lower end of the hull (1), and an electric motor room (5) is provided on the right side of the inner cavity of the cabin (2).

[0004] Although the aforementioned patented amphibious vessel integrates the tracks and the propeller for wave resistance into one unit for roll reduction, its drawback is that the working angle / position of the track assembly and propeller assembly cannot be adjusted, resulting in poor roll reduction effect and limited application. It is only suitable for wave resistance in small waves and has low practicality.

[0005] For example, Chinese patent CN203727623U discloses an externally retractable marine anti-roll fin, including a hull (2), a single-end output push-pull hydraulic device (1), and a fin (6). The single-end output push-pull hydraulic device (1) is movably mounted on the hull (2). Its feature is that one side of the fin (6) is hinged to the hull (2), and a connecting rod (4) is installed between the output end (3) of the single-end output push-pull hydraulic device (1) and the fin (6).

[0006] Although the anti-roll fin is applied to the hull, its overall structure is relatively simple and its size is small, resulting in an unsatisfactory anti-roll effect. Furthermore, the anti-roll fin has a limited operating mode, with only two options: open or closed. When open, it maintains the same operating height, making it unsuitable for use in more complex marine environments.

[0007] In summary, existing transport vessels have poor seakeeping, are prone to bumps on rough roads, and have a low sortie rate, making it difficult to meet the needs of routine transportation use. Furthermore, some transport vessels are equipped with anti-roll propellers on their tracked systems, but the anti-roll effect is poor and they lack protection, making them easy to damage.

[0008] Therefore, we propose a roll-damping fin assembly for a linked seagoing walking mechanism, an amphibious vessel, and its operation method. Summary of the Invention

[0009] In response to the shortcomings of the existing production technology, the applicant provides a roll-damping fin assembly with a linked seakeeping running mechanism, an amphibious boat, and its operation method, which can protect the roll-damping propeller, reduce ship rolling and oscillation, effectively improve ship stability, and enhance passenger comfort.

[0010] The technical solution adopted in this invention is as follows:

[0011] A rock damping fin assembly for a linked wave-resistant walking mechanism includes a track assembly and a rock damping fin assembly;

[0012] The track assembly includes:

[0013] The I-beam section has one end that is movable on the carrier and rotates on the carrier by a drive.

[0014] The track section is connected to the end of the I-beam section and moves on the ground via a drive.

[0015] The propeller section is mounted on the side wall of the track section and provides thrust through drive to counteract wave disturbance.

[0016] The anti-roll fin assembly includes:

[0017] Anti-roll fin mechanism;

[0018] The folding mechanism is used to control the retraction and release of the anti-roll fin mechanism;

[0019] The centering mechanism is used to fix the anti-roll fin mechanism and the I-beam section relative to each other and achieve linkage when the mechanism is released.

[0020] Furthermore, the anti-roll fin assembly also includes a centering mechanism for fixing the anti-roll fin mechanism relative to the I-beam portion and achieving linkage in the released state;

[0021] The centering mechanism includes a screw mechanism and a shaft hole mechanism. The screw mechanism includes a screw body and a motor, and the motor can drive the screw body to move axially. The shaft hole mechanism includes a movable base and a trumpet-shaped docking channel. The movable base can move along the x and y axes on the I-beam body.

[0022] Furthermore, the track section includes tracks and track gear assemblies, the track gear assembly including a driving gear and a driven gear for driving the tracks to move.

[0023] Furthermore, the I-beam section includes an I-beam body, a main hydraulic cylinder, and an auxiliary hydraulic cylinder; the I-beam body is broken in the middle and a shock-absorbing unit is added to enhance the toughness of the I-beam section and prevent rigid fracture; the main hydraulic cylinder is connected to the track section so as to selectively retract the track section into the bottom of the boat or release it by means of contraction.

[0024] Furthermore, the propeller section, including the propeller and motor section, is embedded in the track section, and the rotation of the propeller counteracts part of the disturbance force caused by waves on the hull.

[0025] Furthermore, the anti-roll fin mechanism includes anti-roll fin body I, anti-roll fin body II, and high-performance fiber cloth. The high-performance fiber cloth is disposed between anti-roll fin body I and anti-roll fin body II to absorb wave disturbance forces.

[0026] Furthermore, the folding mechanism, embedded in the bottom of the boat, consists of two parts: a driving hydraulic cylinder and a connecting rod assembly. The driving hydraulic cylinder is internally hinged in the bottom of the boat, and one end of the connecting rod assembly is hinged to the telescopic end of the driving hydraulic cylinder. The connecting rod assembly can be selectively retracted or released. A screw mechanism is mounted on the connecting rod assembly, which consists of a screw body and a motor. The motor can drive the screw body to move axially. A shaft hole mechanism is set on another corresponding mechanism. The shaft hole mechanism has a movable base and a flared docking channel. The movable base is movable, while the flared docking channel is fixed on the movable base, and the flared docking channel has a docking shaft hole for the screw body to extend into.

[0027] An amphibious vehicle includes the aforementioned anti-roll fin assembly of a linked sea-keeping walking mechanism, and grooves are provided on both the left and right sides of the amphibious vehicle for mounting the track assembly and the anti-roll fin assembly, and the depth of the grooves is greater than the thickness of the track assembly and the anti-roll fin assembly after being stored.

[0028] Furthermore, it also includes a control system, which is equipped with a ship attitude sensor to monitor and transmit the ship's attitude information in real time and transmit it to the ship attitude processing terminal. The ship attitude processing terminal performs ship stability adjustment calculations based on the ship attitude information and transmits the calculated data to the hydraulic mechanism, propeller, and anti-roll fins of the tracked chassis system to adjust the ship's attitude in real time.

[0029] An operating method for an amphibious vessel, comprising the following steps:

[0030] Under normal navigation conditions, i.e. when encountering sea state 1-2, both the track assembly and the anti-roll fin assembly are in a retracted state to reduce drag and increase navigation speed.

[0031] When the sea state is upgraded to level 3 or above, the track assembly will be fully deployed to enhance the stability of the hull, while the anti-roll fin assembly will remain retracted.

[0032] When the sea state deteriorates further to level 4 or above, it is necessary not only to fully release the track assembly, but also to initially release the anti-roll fin assembly, and to adjust its angle and position to offset the impact of the waves on the hull.

[0033] When the sea state reaches level 5 or above, the track assembly is still fully deployed to provide maximum stability. At the same time, the anti-roll fin assembly is also fully deployed. All anti-roll fin components, including high-performance fiber cloth, participate in the anti-roll operation to achieve the anti-roll effect and enhance stability.

[0034] In shallow water or on land, the anti-roll fin assembly and cover plate are in a retracted state. On rough terrain, the hydraulic mechanism and vibration damping unit of the track assembly reduce the sway of the amphibious boat.

[0035] In deep water, the various attitudes of the anti-roll fin assembly are adjusted according to different wave levels.

[0036] The beneficial effects of this invention are as follows:

[0037] This invention has a compact and reasonable structure, is easy to use, and is applicable to various sea and road conditions. In wave environments, the amphibious transport boat can deploy the tracked chassis, anti-roll fin assembly, and open the auxiliary sliding door mechanism. The anti-roll fin is linked with the tracked chassis, and the control system can adjust the ship's attitude in real time. At the same time, in complex road conditions, it can make real-time adjustments to achieve shock absorption and stability.

[0038] In addition, the present invention also has the following advantages:

[0039] 1. The amphibious vessel is equipped with a ship attitude sensor and an attitude adjustment terminal, which are used to process the movement of the ship's stability-related mechanisms.

[0040] 2. The track treadle system is equipped with multiple hydraulic cylinders and shock-absorbing springs to absorb the vibration energy of the amphibious vessel on rough terrain, reduce the vibration of the vessel, and stabilize the vessel.

[0041] 3. The track pulley system has multiple hydraulic cylinders, which can adjust the track chassis system in wavy environments, thereby actively reducing sway and accelerating turning speed.

[0042] 4. The tracked chassis system and anti-roll fin system are foldable and can be stored and unfolded as needed;

[0043] 5. The tracked chassis has a built-in anti-roll propeller, which is protected by a sliding door. The sliding door opens when anti-roll is needed; it also opens when turning in water; and it is closed under normal circumstances.

[0044] 6. The anti-roll fin is foldable, with high-strength fiber cloth between the two anti-roll blades. The anti-roll fin can be connected to the I-beam of the track 11 chassis through the alignment mechanism, and it works in conjunction with the track and anti-roll propeller during roll reduction.

[0045] 7. Each of the left and right anti-roll fins is equipped with a motor to connect the lead screw to the track chassis. The head of the lead screw has a position sensor; it can sense the position of the lead screw and perform calibration and alignment of the structure to achieve fast and high-precision docking with the anti-roll fin lead screw.

[0046] 8. In a wave environment, the anti-roll fin is subjected to wave impact and has a complex motion path. The alignment mechanism of the track I-beam has two trolleys, one at the bottom and one at the top, which can slide freely in the plane via a track. It can achieve high-precision alignment with the anti-roll fin. The alignment mechanism has a flared mouth with an electromagnetic attraction function, which improves the success rate of connection with the anti-roll fin. Attached Figure Description

[0065] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0066] Example 1:

[0067] like Figure 2 As shown, this embodiment discloses a roll-damping fin assembly for a linked seakeeping walking mechanism, which includes a track assembly 200 and a roll-damping fin assembly 300. This embodiment details a roll-damping fin assembly for a linked seakeeping walking mechanism, which has a unique structural design, strong functionality, and can effectively improve the stability and seakeeping of amphibious vessels in complex sea conditions.

[0068] like Figure 3 As shown, the track assembly 200 in this embodiment includes a track section 201, an I-beam section 202, and a propeller section 203. The track section 201 is mounted on the amphibious boat 100 via the I-beam section 202, while the propeller section 203 is mounted on the track section 201.

[0069] The track section 201 is driven to move on the ground, including a track 2011 for walking on land or shallow water, and a track gear assembly 2012 for driving the track 2011 to move, such as a drive gear and a driven gear.

[0070] The I-beam section 202, with one end movable on the carrier and rotated on the carrier by a drive, includes an I-beam body 2021, a main hydraulic cylinder 2022, and an auxiliary hydraulic cylinder 2023. The I-beam body 2021 is broken in the middle, and a shock-absorbing unit 204 is added at the break point to enhance the toughness of the I-beam section 202 and prevent rigid fracture. The main hydraulic cylinder 2022 is connected to the track section 201 so that the track section 201 can be selectively retracted into the bottom of the amphibious boat 100 or released by retraction. The I-beam body 2021 is hinged to the track section 201, and the auxiliary hydraulic cylinder 2023 is symmetrically arranged on both sides of the I-beam body 2021 and the track section 201. The track section 201 and the propeller section 203 can be oscillated by the telescopic belt of the auxiliary hydraulic cylinder 2023, and the working mode of seakeeping self-feedback adjustment can be realized in conjunction with the computer algorithm.

[0071] The propeller section 203 includes a propeller and a motor section, which is embedded in the track section 201. The propeller rotation is used to counteract some of the disturbance force caused by waves to the hull.

[0072] like Figure 4 As shown, the anti-roll fin assembly 300 in this embodiment includes a folding mechanism 301, an anti-roll fin mechanism 302, and a centering mechanism 303. The folding mechanism 301 is embedded in the bottom of the amphibious vehicle 100. The anti-roll fin mechanism 302 is mounted on the folding mechanism 301 and can be selectively stored in the bottom of the vehicle or released outside the vehicle by the folding and unfolding of the folding mechanism 301. The centering mechanism 303 can fix the anti-roll fin mechanism 302 in the released state relative to the I-beam body 2021, and realize that the anti-roll fin mechanism 302 swings together during the swing of the driving I-beam body 2021, realizing a linkage working mode.

[0073] The folding mechanism 301 consists of two parts: a driving hydraulic cylinder 3011 and a connecting rod assembly 3012. The driving hydraulic cylinder 3011 is embedded and hinged in the bottom of the boat. One end of the connecting rod assembly 3012 is hinged to the telescopic end of the driving hydraulic cylinder 3011, while the other end is connected to the centering mechanism 303. The connecting rod assembly 3012 is selectively retracted or released by the telescopic movement of the driving hydraulic cylinder 3011, and the anti-roll fin mechanism 302 embedded in the connecting rod assembly 3012 is closed or unfolded.

[0074] The anti-roll fin mechanism 302 consists of anti-roll fin body I 3021, anti-roll fin body II 3022, and a high-performance fiber cloth 3023. The high-performance fiber cloth 3023 is disposed between anti-roll fin body I 3021 and anti-roll fin body II 3022. When the folding mechanism 301 and the anti-roll fin mechanism 302 are deployed, there are two states: the half-open state when the hydraulic cylinder of the connecting rod assembly 3012 extends halfway, and the fully open state when the anti-roll fin is fully extended. When the anti-roll fin mechanism 302 is in the half-open state, although the anti-roll fin body I 3021 and the anti-roll fin body II 3022 are in the half-open state, The fin extends out from the bottom of the boat, but the anti-roll fin I 3021 and anti-roll fin II 3022 are relatively close together. At this time, the high-performance fiber cloth 3023 is not deployed. However, when the anti-roll fin mechanism 302 is in the fully open state, the distance between the anti-roll fin I 3021 and anti-roll fin II 3022 is larger. At this time, the high-performance fiber cloth 3023 is fully deployed. When the waves come into contact with the anti-roll fin I 3021 and anti-roll fin II 3022, they can also come into contact with the high-performance fiber cloth 3023. The flexible bending of the high-performance fiber cloth 3023 absorbs a certain amount of wave disturbance force and plays a certain role in anti-rolling.

[0075] Meanwhile, a cover plate 304 for sealing the anti-roll fin assembly 300 is also provided on the anti-roll fin assembly 300. The cover plate 304 is arranged along the length direction of the anti-roll fin assembly 300. The two sides of the cover plate 304 are movably connected to the connecting rod assembly 3012 through hinged connecting rods. When the connecting assembly 3012 is retracted under the drive of the driving hydraulic cylinder 3011, the cover plate 304 can seal the anti-roll fin mechanism 302.

[0076] The centering mechanism 303 consists of a screw mechanism 3031 and a shaft hole mechanism 3032. The screw mechanism 3031 is mounted on the connecting rod assembly 3012 and consists of a screw body 30311 and a motor 30312. The motor 30312 can drive the screw body 30311 to move axially. The shaft hole mechanism 3032 is set on the I-beam body 2021. The shaft hole mechanism 3032 has a movable base 30321 and a flared docking channel 30322. The movable base 30321 is embedded in the I-beam body 2021 and can move along the x and y axes. The flared docking channel 30322 is fixed on the movable base 30321 and has a docking shaft hole into which the screw body 30311 extends.

[0077] The movement principle of the centering mechanism 303 is as follows: When the folding mechanism 301 is unfolded, the position of the flared docking channel 30322 can be adjusted by the movable base 30321, for example, closer to or farther from the bottom of the boat. When it is closer to the bottom of the boat, the high-performance fiber cloth 3023 is in a half-open state when the screw can be inserted into the flared docking channel 30322. When the movable base 30321 is farther from the bottom of the boat, the high-performance fiber cloth 3023 is in a fully open state when the screw can be inserted into the flared docking channel 30322, which is equivalent to the stepless adjustment of the open state of the high-performance fiber cloth 3023.

[0078] Example 2:

[0079] like Figure 1 As shown, this embodiment discloses an innovatively designed amphibious vessel 100, which integrates advanced technologies of track assembly 200 and anti-roll fin assembly 300, significantly improving its stability and seakeeping under varying sea conditions. The specific structure and advantages of this innovative design will be described in detail below.

[0080] First, the hull design of this amphibious craft 100 fully considers structural strength and navigation efficiency. The hull's smooth lines effectively reduce water resistance and increase speed. At the same time, the selection of hull materials also prioritizes durability and corrosion resistance, ensuring excellent performance in various harsh environments.

[0081] On both sides of the amphibious craft 100, there are first grooves 101 and second grooves 102. The design of these two grooves not only optimizes the spatial layout of the hull but also facilitates the installation of the track assembly 200 and the anti-roll fin assembly 300. Furthermore, in the retracted state, the depth of the grooves is greater than the thickness of the retracted track assembly 200 and anti-roll fin assembly 300, ensuring the flatness of the amphibious craft 100 surface and preventing any protruding parts. The first groove 101 is used to install the track assembly 200; this design makes the tracks smoother during retraction and deployment without affecting the overall aesthetics of the amphibious craft. The second groove 102 is used to install the anti-roll fin assembly 300; this layout maximizes the anti-roll effect of the anti-roll fins, improving the stability of the amphibious craft during navigation.

[0082] The cover plate 304 corresponds to the shape of the second groove 102, which can seal the anti-roll fin mechanism 302 and improve the flatness of the surface of the amphibious boat 100.

[0083] The integrated application of the track assembly 200 and the anti-roll fin assembly 300 is a major highlight of this embodiment. The track assembly 200 provides the amphibious craft with strong land and shallow water mobility, while the anti-roll fin assembly 300 significantly improves stability and seakeeping at sea. The synergistic effect of these two assemblies enables the amphibious craft 100 to achieve efficient and stable navigation in a variety of environments.

[0084] Furthermore, the amphibious craft 100 is equipped with an advanced control system. This system includes ship attitude sensors that monitor and transmit the ship's attitude information in real time to a ship attitude processing terminal. The terminal calculates ship stability adjustments based on this information and transmits the data to the hydraulic mechanisms, propellers, and anti-roll fins of the tracked chassis 2011, enabling real-time adjustments to the ship's attitude. It can also monitor sea conditions and hull status in real time and automatically adjust the operating status of the track assembly 200 and anti-roll fin assembly 300 to achieve optimal navigation performance. This intelligent control system not only improves navigation safety but also reduces operational difficulty, allowing the operator to more easily navigate this high-performance amphibious craft.

[0085] In summary, the amphibious craft 100 disclosed in this embodiment represents a significant advancement in design concept, structural layout, and technological applications. By integrating advanced technologies from the track assembly 200 and the anti-roll fin assembly 300, and equipped with an intelligent control system, this amphibious craft exhibits superior performance in terms of stability, seakeeping, and navigation efficiency.

[0086] Example 3:

[0087] This embodiment discloses in detail the actual navigation operation method of the amphibious boat 100 with the anti-roll fin assembly of the linked seakeeping walking mechanism. The method makes full use of the characteristics of the track assembly 200 and the anti-roll fin assembly 300 to improve the stability and seakeeping of the amphibious boat under various sea conditions.

[0088] During the movement process 1), when the amphibious craft 100 is in normal navigation, i.e., encountering sea state 1-2, the hull can maintain good stability. At this time, the track assembly 200 and the anti-roll fin assembly 300 are both in a retracted state to reduce drag and increase speed. Figure 1 As shown.

[0089] When sea state escalates to level 3 or higher, the amphibious assault enters motion phase 2), at which point the amphibious vessel needs to cope with more complex wave conditions. During this phase, the track assembly 200 is fully deployed to enhance hull stability. However, the anti-roll fin assembly 300 remains retracted during this phase because the wave conditions have not yet reached a level requiring the activation of the anti-roll fins. Figure 2 As shown.

[0090] During the movement process 3), when the sea state further deteriorates to level 4 or higher, the amphibious craft will face even stronger wave impacts. To maintain the stability of the hull, it is necessary not only to fully deploy the track assembly 200, but also to initially deploy the anti-roll fin assembly 300. Anti-roll fin plates I 3021 and II 3022 begin to participate in the anti-roll operation, adjusting their angles and positions to counteract the impact of the waves on the hull, such as... Figure 3 As shown.

[0091] Finally, during the maneuver (4), when sea state reaches its most severe level 5 or higher, the amphibious assault boat needs to cope with extreme wave conditions. At this stage, the track assembly 200 remains fully deployed to provide maximum stability. Simultaneously, the anti-roll fin assembly 300 is also fully deployed, and all anti-roll fin components, including the high-performance fiber cloth 3023, participate in anti-roll operations to reduce roll and enhance stability. This comprehensive approach maximizes the stability of the hull and ensures safe navigation.

[0092] In shallow water or on land, the anti-roll fin assembly 300 and cover plate 304 are in the retracted state. On rough roads, the hydraulic mechanism of the track assembly 200 and the vibration damping unit 204 reduce the swaying of the amphibious boat.

[0093] In deep water (where the tracks cannot contact the ground), the various attitudes of the anti-roll fin assembly 300 are adjusted according to different wave levels. As the wave level increases, the anti-roll fin assembly 300 unfolds more.

[0094] When the tracks are deployed in water to reduce rolling, they do not contact the ground and therefore have no traction.

[0095] The propeller sections 203 on both sides of the track 2011 are designed to operate from sea state 3, improving overall stability.

[0096] In summary, the amphibious craft 100 with its linked seakeeping running mechanism and anti-roll fin assembly disclosed in this embodiment exhibits excellent stability and seakeeping performance during actual navigation. By flexibly adjusting the states of the track assembly 200 and the anti-roll fin assembly 300 according to different sea conditions, this amphibious craft can achieve safe and efficient navigation in various complex environments.

[0097] This invention features a compact and rational structure, is easy to use, and is applicable to various sea and road conditions. In wave environments, the amphibious transport vessel can deploy the tracked 2011 chassis, the anti-roll fin assembly 300, and open the auxiliary sliding door mechanism. The anti-roll fin is linked to the tracked 2011 chassis. The ship attitude sensor in the control system monitors and transmits the ship's attitude information in real time to the ship attitude processing terminal. The ship attitude processing terminal performs ship stability adjustment calculations based on the ship attitude information and transmits the calculated data to the hydraulic mechanism, propeller, and anti-roll fin of the tracked 2011 chassis system to adjust the ship's attitude in real time. When the ship is in complex road conditions, the sliding door mechanism closes, the tracked 2011 chassis deploys and contacts the ground, and the control system transmits the calculated data to the hydraulic mechanism of the tracked 2011 chassis system. The relevant hydraulic mechanism is adjusted in real time to achieve shock absorption and stability.

[0098] 1. The amphibious craft 100 is equipped with a ship attitude sensor and an attitude adjustment terminal, which are used to process the movement of ship stability-related mechanisms;

[0099] 2. The track 2011 pulley system is equipped with multiple hydraulic cylinders and shock-absorbing springs to absorb the vibration energy of the amphibious craft 100 on rough terrain, reduce the vibration of the ship, and stabilize the ship.

[0100] 3. The track 2011 pulley system has multiple hydraulic cylinders, which can adjust the track 2011 chassis system in wavy environments, thereby achieving active roll reduction and accelerating turning speed.

[0101] 4. The tracked 2011 chassis system and anti-roll fin system are foldable and can be stored and unfolded as needed;

[0102] 5. The tracked 2011 chassis has a built-in anti-roll propeller, which is protected by a sliding door. When anti-roll is needed, the sliding door opens; when turning in water, the sliding door opens; under normal circumstances, the sliding door is closed.

[0103] 6. The anti-roll fin is foldable, with high-strength fiber cloth between the two anti-roll blades. The anti-roll fin can be connected to the I-beam of the 2011 track chassis through the alignment mechanism, and it can be linked with the 2011 track and the anti-roll propeller during anti-roll.

[0104] 7. Each of the left and right anti-roll fins is equipped with a motor to connect the lead screw to the 2011 track chassis. The head of the lead screw has a position sensor; it can sense the position of the lead screw and perform calibration and alignment of the structure to achieve fast and high-precision docking with the anti-roll fin lead screw.

[0105] 8. In a wave environment, the anti-roll fin is subjected to wave impact and its movement path is complex. The centering mechanism 303 of the track 2011 I-beam has two trolleys, one at the bottom and one at the top. Through the track, it can achieve free sliding in the plane and can achieve high-precision alignment with the anti-roll fin. The alignment mechanism has a flared mouth with an electromagnetic attraction function, which improves the success rate of connection with the anti-roll fin.

[0106] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.
