Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a ship railing. Background Technology

[0002] Ships are a common means of transportation and play an important role in marine engineering. In marine engineering, ships are used to transport materials to offshore drilling platforms or to transport raw materials for the construction of offshore pipelines. In addition, various marine aquaculture operations also require ships to transport materials.

[0003] Ships typically have railings installed along the edges of the deck to prevent people from falling into the sea due to the ship's rolling motion during navigation, ensuring the safety of personnel. In addition, the railings also prevent cargo or supplies on the deck from falling into the sea due to the ship's movement.

[0004] When ships transport supplies to offshore drilling platforms, dock to load or unload cargo, or for personnel to embark or disembark, they typically maintain a certain distance from these platforms to avoid collisions. This distance depends on the ship's maneuverability; larger ships have lower maneuverability and therefore require a greater distance. Since most ships do not dock completely with the platform, a passageway is needed to connect the ship's deck to the platform. Current methods typically involve manually removing a metal plate from the ship or the platform and placing it between the ship's deck and the docking platform to facilitate personnel embarkation, disembarkation, and cargo handling. However, due to the weight of the metal plate, this manual passageway construction method is quite difficult. To address this, Chinese invention patent application number CN202010133439.7, entitled "A Foldable Telescopic Ship Railing that Can Serve as a Passenger Departure Board," proposes a ship railing comprising a hull. The hull has recesses, and each of the two recesses is connected to the lower ends of a footboard railing via a rotating shaft. A left railing and a right railing are installed on the left and right sides of the footboard railing, respectively, and the lower ends of the left and right railings are fixedly connected to the hull. This foldable telescopic ship railing, which can serve as a passenger departure board, can be easily used as both a railing and a passenger departure board, eliminating the need for metal plates on ships or docks. This invention patent ensures the railing's protective function for personnel on board while eliminating the need for manual handling of heavy metal plates, effectively reducing the difficulty of constructing the passageway and ensuring its stability.

[0005] However, the aforementioned invention patent has relatively complex operating procedures and certain limitations. Ship railings are typically not set too high, usually between 80cm and 120cm, which is sufficient for daily needs. The method described above uses a rotating railing to create a passenger boarding and alighting passage. Therefore, the length of the passage depends on the railing height. If the distance between the ship and the docking platform exceeds the railing height, it becomes difficult to create a passage. Furthermore, waves cause the ship to rock, and if the ship is too close to the docking platform, it may collide with it. Therefore, the aforementioned invention patent is not suitable for medium to large-sized ships.

[0006] Therefore, a ship railing is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a ship railing that solves the problem of insufficient length when using ship railings as a passenger disembarkation passage as mentioned in the background art, and also solves the problem of complex operation when using ship railings as a passenger disembarkation passage.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A ship railing includes two posts for fixing to the ship's deck, the two posts being spaced apart, and a passenger disembarkation railing rotatably installed on the ship's deck between the two posts. The passenger disembarkation railing comprises multiple layers of parallel metal plates, each metal plate having grooves on its bottom left and right sides. Two sliders corresponding to the two grooves are fixedly installed on the top left and right sides of each metal plate. The sliders on the metal plates respectively engage with the grooves on adjacent metal plates. When the passenger disembarkation railing is in a parallel state, the sliders slide along the grooves to allow the metal plates to unfold one by one. The posts are also equipped with features for fixing the passenger disembarkation railing in a vertical state. The passenger disembarkation railing includes a locking assembly. Symmetrical protective railings are also provided on both sides of the passenger disembarkation railing. Each protective railing includes an inner railing and an outer railing. The inner railing is fixedly connected to the posts and the ship's deck. Multiple protective bars are horizontally spaced on the inner railing. The outer railing includes a rotating post vertically mounted on the ship's deck. The rotating post is located outside the inner railing and closer to the posts. A lower crossbar is horizontally fixed to the lower side of the rotating post. Multiple support plates are fixedly installed on the side of each lower crossbar facing away from the inner railing. These support plates are evenly spaced along the length of the lower crossbar. A first magnet for attracting the lower crossbar is fixedly installed on each inner railing.

[0010] The passenger disembarkation railing can rotate vertically and is made of multiple sliding metal plates. This allows it to extend further outwards towards the side of the ship when laid flat to form a disembarkation passage, no longer limited by its height. This allows ships to stop further from the docking platform while still meeting the requirements for the disembarkation passage, preventing collisions with the shore caused by ships approaching too close. When the disembarkation passage is not needed, the railing is secured to two posts using locking components, preventing personnel or cargo from falling from the ship's deck. These locking components can be latches or other components or devices that allow for the detachable and secure attachment of the disembarkation passage to the two posts.

[0011] The passenger disembarkation guardrails, located on both sides, consist of inner and outer railings. The outer railings can rotate horizontally. During the construction of the passenger disembarkation passage, the two outer railings can rotate to the left and right sides of the guardrail, and multiple support plates on the outer railings support the bottom of the guardrail, ensuring its load-bearing capacity. This solves the problem of insufficient strength caused by the sliding connection of multiple metal plates in passenger disembarkation guardrails, ensuring the safety and stability of the guardrails during use.

[0012] Furthermore, since the protective railing extends horizontally along the side of the ship, the outer railing can be designed according to the length of the ship and the actual extension of the passenger disembarkation railing. It is not limited by the height of the ship's railing, allowing the outer railing to adapt to the maximum extension length of the passenger disembarkation railing, ensuring that the bottom of the passenger disembarkation railing can be stably supported, and guaranteeing the safety of the passenger disembarkation railing.

[0013] The first magnet is used to attach the outer railing to the inner railing when a disembarkation passage is not required, thus preventing the outer railing from affecting the ship's navigation.

[0014] Preferably, the outer railing also includes an upper horizontal bar fixedly installed on the rotating column. A connecting rod is provided at the end of the upper horizontal bar furthest from the rotating column, and the two ends of the connecting rod are fixedly connected to the upper and lower horizontal bars, respectively. When the passenger drop-off passage is constructed, the upper horizontal bar provides protection for both sides of the passage, preventing people from falling into the sea from the side of the passage while passing through, thus ensuring the safety of the passenger drop-off passage during use.

[0015] Preferably, each of the lower crossbars is rotatably mounted with multiple overlapping plates, which can rotate vertically up and down. The overlapping plates are used to overlap onto the support plate of another lower crossbar, and the overlapping plates and support plates are aligned one by one, with a support plate between the two overlapping plates on each lower crossbar. When the two lower crossbars are rotated horizontally to be parallel and aligned in length, the overlapping plates on the two lower crossbars are staggered, and the overlapping plates on each lower crossbar are aligned with the support plate on the other lower crossbar. Each upper crossbar is provided with a fixing component for fixing the overlapping plates.

[0016] The overlapping plates on the two outer rails overlap with the support plate on the lower crossbar of the other outer rail, which further increases the support area at the bottom of the metal plate, further ensuring the structural strength and stability of the passenger drop-off passage during its formation and use, and ensuring the safety of the passenger drop-off passage during use.

[0017] Meanwhile, the fixing components are used to secure the free end of the overlapping plate to the upper crossbar when the passenger disembarkation passage is not in use, keeping the overlapping plate vertical. This prevents the overlapping plate from extending horizontally along the edge of the ship's deck and affecting navigation during navigation, and also prevents the overlapping plate from being damaged by collisions with foreign objects. Furthermore, keeping the overlapping plate vertical allows it to work in conjunction with the horizontally installed guardrails on the inner railing to form an interlaced mesh structure, further enhancing the overall protective capability of the railing and preventing cargo on the ship's deck from rolling into the sea through the gaps in the inner railing during navigation. The fixing components can be bolts or other components or devices that can detachably and securely connect the free end of the overlapping plate to the upper crossbar.

[0018] Preferably, each of the lower crossbars has a locking block at the free end of the first overlapping plate near the column, and each of the lower crossbars has a locking groove on its support plate that corresponds to the locking block on the other lower crossbar.

[0019] When using the overlapping plate to connect to the lower crossbar support plate of another outer railing, the locking block on the overlapping plate is inserted into the locking groove of the other outer railing, so that the two outer railings can no longer get closer or further apart. This ensures that the two outer railings will not suddenly separate after the passenger drop-off passage is formed, which would cause the bottom of the passenger drop-off guardrail to lose support. This ensures the stability of the passenger drop-off guardrail during use and avoids safety accidents.

[0020] By utilizing the interlocking action of the locking blocks and slots, two outer rails can be quickly connected. The structure is simple and easy to operate. Simply rotate the overlapping plate to connect the two outer rails. Moreover, when the passenger disembarkation passage is fully formed, the metal plate presses down on the overlapping plate from the top, ensuring that the locking blocks are always pressed inside the slots. The slots restrict the horizontal displacement of the locking blocks, effectively ensuring that the relative position between the two outer rails does not change.

[0021] The reason for setting the locking blocks only on the two overlapping plates closest to the uprights is that the locking blocks and slots are only to prevent the two outer rails from moving away from each other in the horizontal direction when in use. When the passenger aisle is in use, the force on the passenger aisle is downward pressure and not horizontal force. Therefore, it is not necessary to set too many locking blocks and slots to ensure the realization of this function, which helps to save production costs.

[0022] The reason for placing the card blocks and slots on one side near the column, and only having two, is to improve the convenience of storing and resetting the overlapping plate, and to avoid having to manually remove the card blocks from the slots multiple times when the passenger disembarkation passage is retracted.

[0023] In addition, since the disembarkation passage is usually retracted when the ship needs to leave the docked platform, the locking blocks and slots are set on the side near the pillars to facilitate personnel to unlock them from the ship's deck.

[0024] Preferably, the overlapping plate is made of ferromagnetic material. The fixing component includes multiple fixing slots formed on the upper crossbar. The number of fixing slots is the same as the number of overlapping plates on the outer rail, and the positions of the multiple fixing slots correspond one-to-one with the positions of the overlapping plates on the outer rail. When the overlapping plate is rotated to a vertical position, the overlapping plate is inserted into the corresponding fixing slot. The fixing component also includes a rotating shaft horizontally rotatably mounted on the upper crossbar. The rotating shaft passes through each fixing slot on the upper crossbar. Multiple second magnets for adsorbing the overlapping plates are fixedly mounted on the rotating shaft. The multiple second magnets correspond one-to-one with the multiple fixing slots and are located inside the fixing slots. A torsion spring for driving the rotating shaft to return to its original position is also provided on the upper crossbar.

[0025] By incorporating a second magnet, resetting the overlapping plate becomes much easier. Simply extend your hand from the inner railing of the ship and rotate the overlapping plate upwards to the desired position; the second magnet will then hold the plate in place, preventing it from being horizontal and affecting navigation. Furthermore, by fixing multiple second magnets to a rotating shaft, when it's necessary to release the overlapping plate from its fixing slot and place it onto the support plate of another outer railing, simply rotate the shaft to release the magnetic attraction. This allows all overlapping plates on the same outer railing to simultaneously rotate out of their fixing slots and onto the support plate of another outer railing, enabling rapid connection between two outer railings. This further improves the convenience and speed of establishing a passenger disembarkation passageway on the ship's railings.

[0026] Preferably, a plurality of protrusions are also fixedly installed on the rotating shaft. The protrusions are all made of non-ferromagnetic material. The plurality of protrusions correspond one-to-one with a plurality of fixing grooves and are located inside the fixing grooves. The protrusions are arc-shaped.

[0027] By incorporating protrusions, the volume of these protrusions compresses the overlapping plate as the shaft rotates, pushing the plate outward from the fixed groove. This allows the overlapping plate to tilt and, under its own weight, rotate downwards around the hinge point, overlapping onto the support plate of the other outer rail. This prevents the second magnet from detaching from the overlapping plate after the shaft rotates, thus ensuring the plate's stability during use.

[0028] The bumps are made of non-ferromagnetic materials, which effectively prevents the magnetism of the second magnet from being transferred to the bumps, ensuring that the bumps will not attract the overlapping plates, and further guaranteeing the effectiveness of the ship railings during use.

[0029] Preferably, each of the metal plates has multiple strip holes, which are evenly arranged on the surface of the metal plates and penetrate the surface of the metal plates. When the metal plates are parallel to the overlapping plates, the strip holes are perpendicular to the space of the overlapping plates.

[0030] The perforated design helps reduce the weight of the metal plates, further reducing the burden on personnel during the rotation and installation or retrieval of the passenger disembarkation railing. Furthermore, multiple perforations increase friction between the disembarkation passage and passengers' shoes, reducing the risk of slipping when boarding or disembarking and ensuring passenger safety. Additionally, it prevents rainwater accumulation in the disembarkation passage during rainy weather, thus preventing slips and falls.

[0031] When the metal plate is parallel to the overlapping plate, the slotted hole is perpendicular to the space of the overlapping plate. This is to create an interlocking state between the overlapping plate and the metal plate with the slotted hole, so as to ensure the overall load-bearing strength of the metal plate after the passenger drop-off passage is formed.

[0032] Preferably, a soft rubber block is fixedly installed on the bottom of the end of each lower crossbar away from the column, and an arc-shaped groove is formed on the bottom of each rubber block.

[0033] When rubber blocks are formed in the passenger disembarkation passage and overlap the platform the ship will approach, or when the passenger disembarkation passage overlaps with the deck of another ship, the rubber blocks increase friction, reduce swaying of the passenger disembarkation passage as people walk through it, improve its stability, and ensure the safety of people boarding and disembarking. Furthermore, the arc-shaped grooves at the bottom of the rubber blocks allow the weight of people walking through the passage and carrying cargo to press down on the blocks. As the blocks are pressed down, air inside the arc-shaped grooves is expelled, creating a negative pressure suction cup that holds the platform in place, further enhancing the stability of the passenger disembarkation passage.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] 1. The ship railing designed in this invention is a retractable passenger disembarkation railing made of multiple metal plates, which can be extended to form a longer passenger disembarkation passage. Furthermore, by setting rotatable outer rails on both sides of the passenger disembarkation railing and setting support plates on the outer rails to support the bottom of the passenger disembarkation railing, the length of the passenger disembarkation railing is increased and the strength of the passenger disembarkation railing is ensured. Moreover, this solution is simple to operate, improves the construction speed of the passenger disembarkation passage, and facilitates the loading and unloading of cargo by personnel on board the ship.

[0036] 2. The ship railing designed in this invention includes an upper horizontal bar on the outer railing. This upper horizontal bar provides protection to both sides of the passenger disembarkation channel after its construction, preventing people from falling into the sea while loading and unloading cargo, effectively protecting personnel safety. Simultaneously, overlapping plates, locking blocks, and slots are provided on the lower horizontal bar, further enhancing the strength of the passenger disembarkation channel while preventing the two outer railings from moving apart during use, thus avoiding a situation where the bottom of the passenger disembarkation railing is unsupported.

[0037] 3. The ship railing designed in this invention is also equipped with a fixing component consisting of a rotating shaft and a second magnet. The rotating shaft can simultaneously control multiple overlapping plates on the same outer railing, eliminating the need for manual overlapping of each plate onto the support plate on another outer railing. This further ensures the ease of operation of the ship railing and improves the speed at which the ship railing forms a passenger disembarkation passage. Attached Figure Description

[0050] Please see Figures 1 to 11 The present invention provides a ship railing, the technical solution of which is as follows:

[0051] A type of ship railing, reference Figure 1 , Figure 8 , Figure 10 as well as Figure 11 The system includes two uprights 2 for fixing to the ship's deck 1, with the two uprights 2 spaced apart. A passenger disembarkation railing 3 is rotatably installed on the ship's deck 1 between the two uprights 2. The passenger disembarkation railing 3 includes multiple parallel metal plates 301. In this embodiment, the passenger disembarkation railing 3 will be described as having two metal plates 301. All metal plates 301 are made of ferromagnetic metal, meaning that the metal plates 301 can be attracted by a magnet. The bottom surface of the metal plate 301 is provided with grooves 302 on both the left and right sides. Each metal plate 301 has two sliders 303 fixedly installed on its top surface, which correspond to the two grooves 302. The sliders 303 on the metal plate 301 are respectively inserted into the grooves 302 on the adjacent metal plate 301. Each column 2 is also equipped with a locking assembly 4 for fixing the passenger disembarkation railing 3 when it is in a vertical state. The locking assembly 4 includes a rotating plate 401 rotatably mounted on it. The rotating plate 401 is located on the outside of the ship deck 1. The rotating plate 401 can rotate in a vertical plane. A third magnet 402 is fixed on the end face of the rotating plate 401.

[0052] refer to Figure 10 and Figure 11Each metal plate 301 has multiple strip holes 14, which are evenly arranged on the surface of the metal plate 301 and penetrate through the surface of the metal plate 301. When the metal plate 301 is parallel to the overlapping plate 5026, the strip holes 14 are spatially perpendicular to the overlapping plate 5026.

[0053] refer to Figure 1 and Figure 2 On the left and right sides of the passenger disembarkation railing 3, there are also symmetrical protective railings 5. The protective railings 5 ​​include an inner railing 501 and an outer railing 502. The outer railing 502 is located on the outside of the ship deck 1 relative to the inner railing 501. The inner railing 501 is fixedly connected to the column 2 and the ship deck 1. Multiple protective bars 5011 are also installed horizontally at intervals on the inner railing 501.

[0054] refer to Figure 1 , Figure 2 as well as Figures 5 to 8 The outer railing 502 includes a rotating column 5021 vertically rotatably mounted on the ship's deck 1. The rotating column 5021 is located outside the inner railing 501 and on the side closest to the upright column 2. A lower crossbar 5022 is horizontally fixed to the lower side of the rotating column 5021. The lower crossbar 5022 is made of ferromagnetic metal. Multiple support plates 5023 are fixedly installed on the side of each lower crossbar 5022 away from the inner railing 501. The multiple support plates 5023 are evenly spaced along the length of the lower crossbar 5022. Multiple overlapping plates 5026 are rotatably mounted on each lower crossbar 5022. The overlapping plates 5026 are made of ferromagnetic material. The overlapping plates 5026 and the support plates 5023 are aligned one by one, and there is a support plate 5023 between the two overlapping plates 5026 on each lower crossbar 5022; when the two lower crossbars 5022 are rotated horizontally to be parallel and aligned in length, the overlapping plates 5026 on the two lower crossbars 5022 are staggered, and the overlapping plate 5026 on each lower crossbar 5022 is aligned with the support plate 5023 on the other lower crossbar 5022. The free end of the first overlapping plate 5026 near the column 2 on each lower crossbar 5022 is provided with a locking block 7, and the support plate 5023 on each lower crossbar 5022 is provided with a locking groove 8 that corresponds to the locking block 7 on the other lower crossbar 5022.

[0055] refer to Figure 2 and Figure 3 Each lower crossbar 5022 has a soft rubber block 15 fixedly installed on the bottom of the end away from the column 2, and each rubber block 15 has an arc-shaped groove 16 on its bottom.

[0056] refer to Figure 1 , Figure 2Each outer rail 502 also includes an upper horizontal bar 5024 horizontally fixedly installed on the rotating column 5021. A connecting rod 5025 is provided at one end of the upper horizontal bar 5024 away from the rotating column 5021. The two ends of the connecting rod 5025 are fixedly connected to the upper horizontal bar 5024 and the lower horizontal bar 5022, respectively. Each upper horizontal bar 5024 is provided with a fixing component for fixing the overlapping plate 5026.

[0057] refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 9 The fixing component includes multiple fixing slots 9 formed on the upper crossbar 5024. The number of fixing slots 9 is the same as the number of overlapping plates 5026 on the outer rail 502. The positions of the multiple fixing slots 9 correspond one-to-one with the positions of the overlapping plates 5026 on the outer rail 502. When the overlapping plate 5026 is rotated to the vertical position, the overlapping plate 5026 is inserted into the corresponding fixing slot 9. The fixing component also includes a rotating shaft 10 that is horizontally rotatably mounted on the upper crossbar 5024. The rotating shaft 10 passes through each fixing slot 9 of the upper crossbar 5024. Multiple second magnets 11 for adsorbing the overlapping plates 5026 are fixedly mounted on the rotating shaft 10. The multiple second magnets 11 correspond one-to-one with the multiple fixing slots 9 and are located inside the fixing slots 9. A torsion spring 12 for driving the rotating shaft 10 to reset is also provided on the upper crossbar 5024. Multiple protrusions 13 are also fixedly installed on the rotating shaft 10. The protrusions 13 are all made of non-ferromagnetic material. The multiple protrusions 13 correspond one-to-one with multiple fixing grooves 9 and are located inside the fixing grooves 9. The protrusions 13 are arc-shaped. When the rotating shaft 10 rotates, the protrusions 13 push the overlapping plate 5026 outward from the fixing groove 9.

[0058] refer to Figure 7 Each inner rail 501 is fixedly equipped with a first magnet 6 for adsorbing the lower crossbar 5022.

[0059] When using, refer to Figure 1 and Figure 2 as well as Figure 8 During normal navigation, the two metal plates 301 serving as the disembarkation railing 3 are retracted and kept vertical. The rotating plate 401 of the locking assembly 4 rotates to a horizontal position and is flush with the surface of the metal plates 301. The third magnet 402 on the locking assembly 4 adheres to the surface of the metal plates 301, ensuring that the metal plates 301 remain vertical throughout the navigation process, thus providing protection for the disembarkation railing 3. The rotating plate 401 is located on the outer side of the ship's deck 1 to prevent personnel from accidentally pushing the metal plates 301 outward from the ship's deck 1, causing the disembarkation railing 3 to detach from the third magnet 402, and preventing the disembarkation railing 3 from being accidentally opened outward from the ship's deck 1, which could result in personnel falling into the sea.

[0060] While the ship is sailing, refer to Figure 1 and Figure 2 The outer rail 502 rotates to be parallel to the inner rail 501, and is then attracted and fixed to the inner rail 501 by the first magnet 6. All the overlapping plates 5026 on the outer rail 502 are housed in their corresponding fixing slots 9 on the outer rail 502, and are attracted to the inside of the fixing slots 9 by the second magnet 11 inside the fixing slots 9. The vertically positioned overlapping plates 5026, together with the protective rods 5011 on the inner rail 501, form a crisscrossing mesh structure, which can improve the protection of personnel or cargo during ship navigation.

[0061] refer to Figure 4 , Figure 5 and Figure 9 When a ship needs to dock to facilitate passenger disembarkation and alighting, after the ship docks, personnel on board push two outer railings 502 from the ends of the rotating posts 5021 furthest from the outer railings 502 on the ship's deck 1. This disengages the outer railings 502 from the first magnet 6 and allows them to rotate horizontally around the rotating posts 5021, extending them onto the shore platform where they need to be moored, with the rubber blocks 15 at the bottom of the outer railings 502 contacting the platform. Rotation stops when both outer railings 502 are perpendicular to the surface of the metal plate 301, at which point they are parallel. To easily determine the position of the two outer railings 502 perpendicular to the metal plate 301, positioning blocks can be installed on the ship's deck 1 for quick location. When both outer rails 502 are perpendicular to the surface of the metal plate 301, the shaft 10 on one of the outer rails 502 is turned so that the magnetic poles of all the second magnets 11 on the shaft 10 are simultaneously rotated and offset from all the overlapping plates 5026. When the shaft 10 is rotated, the protrusions 13 on the shaft 10 press the overlapping plates 5026 toward the outside of the fixing groove 9.

[0062] refer to Figure 5 , Figure 7 and Figure 9 Once the overlapping plate 5026 loses the attraction of the second magnet 11 and is pressed outwards towards the fixing groove 9, it is in an inclined state. Under its own weight, the overlapping plate 5026 rotates downwards around the hinge shaft below it and overlaps onto the support plate 5023 on the other outer rail 502. The locking block 7 on the overlapping plate 5026 closest to the rotating column 5021 on the outer rail 502 will engage with the locking groove 8 on the overlapping plate 5026 of the other outer rail 502. The relative positions of the two outer rails 502 are thus fixed. When the rotating shaft 10 is released, the torsion spring 12 drives the rotating shaft 10 and its second magnet 11 and protrusion 13 to reset.

[0063] refer to Figure 7Then, rotate the pivot 10 on the other outer rail 502 in the same way as described above, so that the overlapping plate 5026 on the other outer rail 502 also overlaps onto the support plate 5023 of the opposite outer rail 502.

[0064] Then, reach your hand to the side of the passenger disembarkation railing 3 facing the outside of the ship deck 1 and rotate the rotating plate 401 of the locking assembly 4 to make the rotating plate 401 misalign with the metal plate 301 of the passenger disembarkation railing 3, so that the third magnet 402 no longer attracts the metal plate 301, and the rotating plate 401 no longer obstructs the rotation of the metal plate 301.

[0065] Subsequently, reference Figure 8 , Figure 10 and Figure 11 The metal plate 301 is pushed towards the shore, causing it to rotate around the lower hinge axis and overlap the surface of the overlapping plate 5026. Then, the metal plate 301 is pushed to slide along the groove 302 of another metal plate 301, allowing the two metal plates 301 to slide and unfold towards the shore between the two outer railings 502. This ultimately forms a disembarkation passage for passengers to board and disembark. The upper crossbars 5024 of the outer railings 502 protect the disembarkation passage from both sides.

[0066] When it is necessary to reclaim the passenger drop-off lane, refer to Figure 8 Personnel first retreat from the disembarkation passage towards the ship, squatting down as they do so to pull the metal plate 301 back together along the slide groove 302. When personnel reach the ship's deck 1, they first rotate the overlapped metal plate 301 and lay it flat on the deck 1. Then, standing on the deck 1, they hold onto the pillar 2 with one hand and use the other hand to rotate the overlapping plate 5026 on the two outer rails 502 closest to the rotating pillar 5021, causing the locking block 7 on it to disengage from the locking groove 8. The two overlapping plates 5026 are then rotated to a vertical position and repositioned inside the fixing groove 9, where they are attracted and fixed by the second magnet 11.

[0067] After both card blocks 7 are removed from the card slot 8, refer to Figure 1 and Figure 8 Rotate the two outer railings 502 to their initial positions, where they are attracted and fixed to the inner railing 501 by the first magnet 6. Then, rotate the metal plate 301 placed on the ship deck 1 to a vertical position. Holding it with one hand, extend the other hand to the outside of the ship deck 1 and rotate the rotating plate 401 of the locking assembly 4. This allows the third magnet 402 on the rotating plate 401 to re-attract the metal plate 301, thus completing the reset of the passenger disembarkation railing 3.

[0068] After completing the above steps, refer to Figure 1Then, extend your hand from the inner rail 501 and rotate the overlapping plates 5026 on the two outer rails 502 one by one to a vertical position, so that the overlapping plates 5026 are re-attracted and fixed by the second magnet 11, thus completing the entire reset operation.

[0069] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
