Description

Technical Field

[0001] This utility model relates to the field of port and waterway engineering technology, specifically to a floating dock with a follow-up floating platform and an adaptive ladder. Background Technology

[0002] In port operations, ship berthing, and waterfront development in oceans and rivers, floating docks are one of the core facilities connecting land and water facilities (such as ships and floating platforms). Due to periodic rises and falls in sea level (such as tides) or non-periodic changes in water level (such as rainfall in the basin and the scheduling of upstream water conservancy projects), traditional floating docks face serious adaptability challenges.

[0003] Traditional floating docks typically use fixed or only slightly floating structures for their pontoon platforms. As sea levels rise and fall, the relative height between the pontoon platform and the vessel waiting to be docked (especially the stern deck) changes significantly. If the pontoon platform cannot rise and fall synchronously with the water level, either the excessive height difference between it and the stern will cause difficulties for personnel passage and hinder cargo loading and unloading, or it will force the vessel to frequently adjust its draft to accommodate the pontoon platform, severely impacting operational efficiency and safety. Furthermore, the ladders connecting the platform (fixed or semi-fixed on the land side) to the pontoon platform are traditionally designed as rigid or simple hinged structures. When the pontoon platform rises and falls with the water level, rigid ladders, due to their fixed length or angle, will experience excessive stretching, compression, or even breakage. While hinged ladders can adjust their angle slightly, they are difficult to accommodate larger displacements of the pontoon platform and have poor stability during passage, easily causing personnel to slip due to sudden angle changes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a floating dock with a follow-up floating box platform and an adaptive ladder. The platform includes a platform, one end of which is connected to land. The platform is equipped with mooring bollards, and there are multiple mooring bollards. A floating dock is located on one side of the platform, comprising a floating box platform. The floating box platform has a movable guide rail clamp on its side, which is engaged with an H-shaped guide rail. The H-shaped guide rail is fixed to the side of the land. One end of a ladder is located on the floating box platform, and the other end of the ladder is located on the platform.

[0005] The structure of the floating platform, from top to bottom, consists of a wood-plastic composite panel, a rectangular steel pipe, a channel steel frame, and a floating box, and there is more than one floating box.

[0006] One end of the ladder is fixed to the platform via a shore support and is connected to the platform via a transition plate A. The other end of the ladder is connected to the floating platform via a bridge pulley and is connected to the floating platform via a transition plate B.

[0007] The beneficial effects of this utility model are: I. Enhanced Safety: 1. Ensuring the Safety of Personnel and Cargo Passage: Through the cooperation of the guide rail movable clamps and H-shaped guide rails, the floating platform can flexibly adjust its height according to the rise and fall of the sea level, always maintaining a horizontal position with the stern of the ship. This effectively avoids the risk of personnel tripping or slipping during passage due to excessive height difference between the floating platform and the stern of the ship, as well as the risk of damage or falling of cargo due to the drop during loading and unloading, greatly improving the safety of personnel and cargo during the transfer process between the floating dock and the ship.

[0008] 2. Enhanced Ladder Stability: One end of the ladder is connected to the floating platform via a connecting pulley. When the floating platform is raised or lowered, the ladder automatically adjusts to different angles and maintains a stable connection with the floating platform and the main platform via transition plates A and B, respectively. This design ensures a stable passageway under various water levels, reducing safety accidents caused by sudden changes in ladder angle or loose connections with the bridge structure, and further guaranteeing personnel safety.

[0009] II. Enhanced Ease of Use 1. Facilitates Vessel Mooring and Operations: The height of the floating platform can be adjusted in real time according to the water level, allowing various types of vessels to easily moor at the floating dock under different water conditions, without the need to frequently adjust the vessel's draft or find other suitable mooring points due to water level changes. This significantly improves vessel mooring efficiency, saves time and labor costs, and provides great convenience for port operations and water transport.

[0010] 2. Flexible passage adaptable to different water levels: The ladder's adaptive angle adjustment function eliminates concerns about passage difficulties caused by water level changes when moving between the platform and the floating platform. Whether at high or low tide, the ladder allows for smooth movement between the platform and the floating platform, greatly improving the usability of the floating dock under different water conditions.

[0011] III. Enhanced Structural Adaptability and Stability: 1. Adaptation to Sea Level Changes: This floating dock design effectively copes with periodic rises and falls in sea level (such as tides) and non-periodic water level changes (such as floods and dry seasons). Through the sliding connection between the guide rail movable clamps and the H-shaped guide rails, the floating platform can freely rise and fall within a large range of water level changes, ensuring that the floating dock can be used normally under various water level conditions, thus improving the floating dock's adaptability to different aquatic environments and water level changes.

[0012] 2. Enhanced Overall Structural Stability: The floating platform utilizes a composite structure consisting of wood-plastic composite panels, rectangular steel pipes, channel steel frames, and multiple floating boxes. This top-down, rational layout gives the platform high structural strength and stability. The floating boxes provide uniform buoyancy support, while the rectangular steel pipes and channel steel frames enhance overall rigidity, enabling it to better withstand wave impacts, the impact of ships docking, and the loads of personnel and cargo. This extends the service life of the floating dock and reduces maintenance and replacement costs due to structural damage.

[0013] IV. Improving Mooring Efficiency and Flexibility: 1. Meeting the Needs of Multiple Vessels for Mooring: Multiple mooring bollards are installed on the platform, facilitating the simultaneous mooring of multiple vessels. Vessels of different types and sizes can choose the appropriate mooring bollard according to their own needs, improving the mooring efficiency of the floating dock, increasing the vessel capacity of the floating dock at the same time, and meeting the diverse operational needs of the port.

[0014] 2. Facilitates ship mooring operations: The reasonable distribution of bollards makes it easier for crew members to tie the mooring lines to the appropriate bollards when the ship is berthed, reducing the operational difficulty and time consumption during the mooring process, and further improving the efficiency and flexibility of ship berthing.

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] Example 1, as shown in the figure: A floating dock with a follow-up floating box platform and an adaptive ladder includes a platform 8, one end of which is connected to land 3. The platform 8 is equipped with mooring bollards 9, and there are more than one mooring bollard 9. A floating dock is located on one side of the platform 8, including a floating box platform 4. The side of the floating box platform 4 is equipped with a guide rail movable clamp 2, which is engaged with an H-shaped guide rail 1. The H-shaped guide rail 1 is fixed to the side of the land 3. One end of a ladder 6 is located on the floating box platform 4, and the other end of the ladder 6 is located on the platform 8. The structure of the floating box platform 4, from top to bottom, consists of a wood-plastic composite panel 41, a rectangular steel pipe 42, a channel steel frame, and floating boxes 43, and there are more than one floating box 43. One end of the ladder 6 is fixed to the platform 8 via the shore support 10 and is connected to the platform 8 via the transition plate A5. The other end of the ladder 6 is connected to the floating platform 4 via the bridge pulley 11 and is connected to the floating platform 4 via the transition plate B7. The surface of the ladder 6 is made of aluminum alloy checkered plate.

[0021] I. Overall Structure Assembly and Initialization (a) First, vertically fix the H-shaped guide rail to the side of land 3 (such as the wharf wall), ensuring that the guide rail is firmly installed in the vertical direction (consistent with the direction of sea level rise and fall), and its length must cover the maximum water level change range that the floating wharf may face. Then, make a stable connection between one end of the platform 8 and land 3 (through concrete foundation, steel structure support, etc.), and arrange multiple mooring bollards 9 on the platform 8 as needed for berthing and fixing of ships.

[0022] (II) Next, assemble the floating platform 4 of the floating dock: The structure of the floating platform 4, from top to bottom, consists of a wood-plastic composite panel 41 (serving as a passage surface, possessing anti-corrosion and anti-slip properties), a rectangular steel pipe 42 (bearing the main load and providing structural strength), a channel steel frame (enhancing overall rigidity and stability), and multiple floating boxes 43 (providing buoyancy, allowing the floating platform 4 to float with the water level). Install movable guide rail clamps 2 on the side of the floating platform 4, and snap the clamps onto the H-shaped guide rails. At this time, the floating platform 4 can slide vertically along the H-shaped guide rails, and the cooperation between the clamps and the guide rails must ensure that the floating platform 4 is relatively stable in the horizontal direction, and can only rise and fall along the guide rails.

[0023] (III) Finally, the ladder 6 is arranged: one end of the ladder 6 is fixed to the platform 8 through the shore support 10 and overlaps with the passage surface of the platform 8 through the transition plate B; the other end of the ladder 6 is connected to the floating box platform 4 through the bridge pulley 11 and overlaps with the plastic wood panel 41 of the floating box platform 4 through the transition plate A, so that the ladder 6 forms a transition channel between the platform 8 and the floating box platform 4.

[0024] II. Adaptive Working Process During Sea Level Rise and Fall (a) As the sea level rises, the floating platform 4 will rise with the water level.

[0025] As the sea level rises, the buoyancy of the pontoon 43 increases, propelling the entire pontoon platform 4 upward along the H-shaped guide rail (the movable clamp 2 moves upward synchronously along the H-shaped guide rail). During this process...

[0026] The height of the floating platform 4 increases with the rise in water level, and it always remains level with the stern of the ship (the ship that rises with the water level), ensuring that there is no significant height difference between the stern of the ship and the plastic wood panel 41 of the floating platform 4 after the ship is docked, which facilitates the passage of personnel and goods.

[0027] The ladder 6 is connected to the floating platform 4 at one end via the connecting pulley 11. When the floating platform 4 rises, the connecting pulley 11 will drive the floating platform 4 end of the ladder 6 to move upward and outward, so that the ladder 6 as a whole presents a change of "the angle of inclination towards the floating platform 4 decreases" (or the angle is adjusted according to the actual structure). At the same time, the transition plate A moves synchronously with the floating platform 4, always maintaining a stable connection with the panel of the floating platform 4. The platform 8 end of the ladder 6 is fixed by the shore support 10, and the transition plate B also continuously and stably connects with the panel of the platform 8, ensuring the continuous passage of the ladder 6 throughout the entire process.

[0028] (ii) As sea level drops, floating platform 4 will decrease with the water level. As the sea level drops, the buoyancy of pontoon 43 decreases, and pontoon platform 4 slides downward along the H-shaped guide rail under its own weight and possible loads (the movable clamp 2 of the guide rail moves downward synchronously along the H-shaped guide rail). During this process: The height of the floating platform 4 decreases as the water level drops, and it always remains level with the stern of the ship (which moves with the water level) to avoid excessive height difference between the stern and the floating platform 4, which could cause passage obstruction.

[0029] As the floating platform 4 end of the ladder 6 moves downward and toward the platform 8, the connecting pulley 11 causes the ladder 6 to exhibit a change in "increasing tilt angle toward the floating platform 4". The transition plate A continues to smoothly overlap with the panel of the floating platform 4; the transition plate B at the platform 8 end of the ladder 6 also always smoothly overlaps with the panel of the platform 8, ensuring that the ladder 6 can still move safely and smoothly during the angle change process.

[0030] I. Improve safety during use 1. Ensuring the safety of personnel and cargo passage: Through the cooperation of the movable clamp 2 and the H-shaped guide rail, the floating platform 4 can flexibly adjust its height according to the rise and fall of the sea level, always maintaining a horizontal position with the stern of the ship. This effectively avoids the risk of personnel tripping or slipping during passage due to excessive height difference between the floating platform 4 and the stern of the ship, as well as the risk of damage or falling of cargo due to the drop during loading and unloading, greatly improving the safety of personnel and cargo during the transfer between the floating dock and the ship.

[0031] 2. Enhanced stability of ladder 6: One end of ladder 6 is connected to the floating platform 4 via a connecting pulley 11. When the floating platform 4 is raised or lowered, ladder 6 automatically presents different angles and maintains a stable connection with the floating platform 4 and platform 8 via transition plates A and B, respectively. This design ensures that ladder 6 provides a stable passageway under various water levels, reducing safety accidents caused by sudden angle changes or loose connections between ladder 6 and the bridge structure, and further guaranteeing personnel safety.

[0032] II. Improve ease of use 1. Facilitates vessel berthing and operations: The height of the floating platform 4 can be adjusted in real time according to the water level, allowing various types of vessels to easily berth at the floating dock under different water conditions, without the need to frequently adjust the vessel's draft or find other suitable berthing points due to water level changes. This significantly improves vessel berthing efficiency, saves time and labor costs, and provides great convenience for port operations and water transport.

[0033] 2. Flexible passage adaptable to different water levels: The adaptive angle adjustment function of ladder 6 eliminates concerns about passage difficulties caused by water level changes when personnel move between platform 8 and floating platform 4. Whether at high or low tide, personnel can smoothly move between platform 8 and floating platform 4 via ladder 6, greatly improving the usability of the floating dock under different water level conditions.

[0034] III. Enhancing Structural Adaptability and Stability 1. Adaptability to Sea Level Changes: This floating dock design effectively copes with periodic rises and falls in sea level (such as tides) and non-periodic water level changes (such as floods and dry seasons). Through the sliding connection between the guide rail movable clamp 2 and the H-shaped guide rail, the floating platform 4 can freely rise and fall within a large range of water level changes, ensuring that the floating dock can be used normally under various water level conditions, thus improving the floating dock's adaptability to different aquatic environments and water level changes.

[0035] 2. Enhanced Overall Structural Stability: The floating platform 4 adopts a composite structure consisting of wood-plastic composite panels 41, rectangular steel pipes 42, channel steel frames, and multiple floating boxes 43. This rational top-to-bottom layout gives the floating platform 4 high structural strength and stability. The floating boxes 43 provide uniform buoyancy support, while the rectangular steel pipes 42 and channel steel frames enhance overall rigidity, enabling it to better withstand wave impacts, the impact of ships docking, and the loads of personnel and cargo. This extends the service life of the floating dock and reduces maintenance and replacement costs due to structural damage.

[0036] IV. Improve mooring efficiency and flexibility 1. Meeting the needs of multiple vessels: Platform 8 is equipped with multiple bollards 9, which facilitates the simultaneous berthing of multiple vessels. Vessels of different types and sizes can choose the appropriate bollard 9 for mooring according to their own needs, improving the mooring efficiency of the floating dock, increasing the vessel capacity of the floating dock at the same time, and meeting the diverse operational needs of the port.

[0037] 2. Facilitates ship mooring operations: The reasonable distribution of the bollards 9 makes it easier for the crew to tie the mooring lines to the appropriate bollards 9 when the ship is berthed, reducing the difficulty and time consumption of the mooring process, and further improving the efficiency and flexibility of ship berthing.
