Description

Technical Field

[0001] This invention relates to the field of temporary dock technology, specifically to a temporary dock structure that adapts to rising and falling tides and its usage method. Background Technology

[0002] Currently, temporary docks mostly use floating structures in conjunction with guide piles for positioning. The buoyancy of the floating bodies adapts to changes in water level at different tide levels. Some temporary docks are also equipped with deployable auxiliary floating bodies or platforms to improve stability during use and adapt to the docking and operation needs in different scenarios. Due to their simple structure and convenient assembly and disassembly, these temporary docks are widely used in temporary construction, emergency rescue, and scenic area landing scenarios.

[0003] While conventional temporary wharves typically include floating bodies, guide piles, and deployable platforms, the deployment and retraction of these platforms largely rely on manual operation and cannot automatically adjust to changes in tide levels. During high tide, the buoyancy of the floating bodies increases. If the platform cannot move towards the center, the overall center of gravity of the floating bodies will be too high, leading to swaying and tilting, which affects the safety of vessel berthing and personnel passage. During low tide, the buoyancy of the floating bodies decreases as the water level drops. If the platform cannot deploy outwards, the support width of the floating bodies will be insufficient, resulting in excessive stress concentration and a risk of capsizing. This approach fails to meet the operational requirements of temporary wharves. Therefore, an adaptive high- and low-tide temporary wharf structure and its usage method are proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adaptive tidal temporary wharf structure and its usage method, thereby solving the technical problems of temporary wharves being unable to automatically adjust platform status according to tide levels, having poor stability, and requiring high manual operation intensity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a temporary wharf structure and its usage method that is adaptive to tides, comprising a shore platform and prestressed square piles, wherein a fixed steel approach bridge is installed at the top of both the shore platform and the prestressed square piles, and a movable steel approach bridge is hinged to the side of the top of the prestressed square piles, and a main floating wharf is hinged to the outer end of the movable steel approach bridge. Auxiliary floating docks are installed on both sides of the main floating dock. Limiting sleeves are installed on the lower surface of the main floating dock. Guide piles are inserted inside the limiting sleeves. The prestressed square piles and guide piles are driven into the seabed. The protective shell is installed on the outside of the main floating body dock. Position sensors are inserted into the inner side of the guide piles. Detection probes are embedded in the inner wall of the limiting sleeve. A bearing seat is connected to the inner wall of the protective shell. A bidirectional lead screw is inserted into the inside of the bearing seat. The slider is screwed to both sides of the bidirectional lead screw. The outer end of the slider is connected to the surface of the auxiliary floating body dock. A first motor is installed at the bottom of the inner cavity of the protective shell. Gears are installed at corresponding positions on the outside of the first motor and the bidirectional lead screw.

[0006] A method of using an adaptive tidal temporary wharf structure, based on any one of the aforementioned adaptive tidal temporary wharf structures, includes the following steps: S1 construction deployment: First, prestressed square piles and guide piles are driven into the seabed. Fixed steel approach bridges are installed on the shore platform and the top of the prestressed square piles. The movable steel approach bridge is hinged to the side of the top of the prestressed square piles. Then, the outer end of the movable steel approach bridge is hinged to the main floating dock. S2 component debugging: Check the installation status of the main floating dock, start the first motor to test the gear transmission and bidirectional screw rotation performance, and ensure that the slider can drive the auxiliary floating dock to move smoothly. S3 adaptive operation: After the wharf is set up, when the tide rises, the main floating wharf and the auxiliary floating wharf rise with the water level, causing the limit sleeve to move upward along the guide pile. The limit sleeve triggers the position sensor at the corresponding position inside the guide pile. The feedback signal from the position sensor controls the first motor to start, which drives the bidirectional screw to rotate through the gear, causing the slider to move the auxiliary floating wharf towards the center of the main floating wharf, thus lowering the overall center of gravity. When the tide recedes, the main floating dock and the auxiliary floating dock descend with the water level. The limit sleeve triggers the low position sensor inside the guide pile, which controls the first motor to brake and rotate in the reverse direction. This drives the bidirectional screw to rotate in the reverse direction, causing the slider to push the auxiliary floating dock to unfold outward and expand the support width. S4 auxiliary protection: According to the changes in tide level, the second motor is started synchronously to drive the lead screw to rotate. Through the hinge joint and hinge lug, the baffle rotates around the hinge rod. During low tide, the baffle is in a horizontal state, and during high tide, the baffle is tilted upward, thus completing the entire process of the wharf's adaptive use of high and low tide.

[0007] Preferably, guardrails are installed on the outer side of the walking surfaces of the fixed steel approach bridge, the movable steel approach bridge, and the auxiliary floating dock. Anti-slip mats are laid on the walking surfaces of the fixed steel approach bridge, the movable steel approach bridge, and the auxiliary floating dock. The guardrails can effectively prevent people and objects from falling from the edge of the dock, ensuring passage safety. The anti-slip mats can increase the friction of the walking surface, preventing people from slipping and falling due to the wet walking surface, further improving the safety and comfort of dock use.

[0008] Preferably, guide rods are laterally connected to both sides of the main floating dock, and the guide rods penetrate the interior of the secondary floating dock. Insert plates are connected to both sides of the main floating dock above the guide rods, and the insert plates are inserted into the interior of the secondary floating dock. The guide rods guide the movement of the secondary floating dock and prevent it from deviating during movement; the insert plates position the moved secondary floating dock, enhancing the connection stability between the secondary floating dock and the main floating dock and preventing swaying.

[0009] Preferably, the threads on both sides of the bidirectional lead screw are arranged in opposite directions. The middle part of the bidirectional lead screw is connected to the inside of the bearing housing through a ball bearing. Both ends of the bidirectional lead screw penetrate through both sides of the protective shell. A sealing gasket is engaged at the penetration point between the bidirectional lead screw and the protective shell. The reverse threads enable the sliders on both sides to move synchronously in opposite directions, ensuring that the expansion or contraction of the auxiliary floating body dock is synchronous and smooth. The ball bearing reduces the rotational resistance of the bidirectional lead screw, and the sealing gasket prevents seawater from seeping into the protective shell, protecting the internal components from corrosion.

[0010] Preferably, the side of the auxiliary floating dock is connected to a hinged bracket, a swing arm is inserted into the upper inner side of the hinged bracket, a hinged rod is movably inserted into the lower inner side of the hinged bracket, and a baffle is connected to the outer end of the hinged rod. The cooperation of the hinged bracket, the swing arm and the hinged rod provides stable installation support for the baffle, ensuring that the baffle can rotate flexibly and that the baffle can smoothly switch states during high and low tides, so as to give full play to its protective function.

[0011] Preferably, a lead screw is screwed internally into the swing arm, and a second motor is mounted on the top of the swing arm via a bracket. The rotor of the second motor is coaxially connected to the lead screw, and a hinge joint is coaxially mounted on the outer end of the lead screw. A hinge lug is movably connected to the outside of the hinge joint, and the outer end of the hinge lug is connected to the surface of the baffle. The linkage between the second motor and the lead screw can precisely control the rotation angle of the baffle, allowing the baffle to adapt to different moisture level requirements. The cooperation between the hinge joint and the hinge lug ensures flexible rotation of the baffle, improving the accuracy and reliability of baffle adjustment.

[0012] Preferably, in step S1, before driving the prestressed square piles and guide piles into the seabed, the seabed of the construction area is leveled, and sharp debris and protruding rocks on the seabed surface are removed. Then, a positioning frame is used to position the prestressed square piles and guide piles to ensure that they are perpendicular to the seabed surface and the spacing is uniform. During the driving process, the verticality of the piles is monitored in real time. If tilting occurs, the driving angle is adjusted immediately. After driving is completed, the connection between the pile and the seabed is reinforced and filled with anti-corrosion sealing material to prevent seawater from seeping into the gap between the pile and the seabed and causing pile corrosion. At the same time, it is ensured that the connection surfaces of the fixed steel approach bridge and the shore platform and prestressed square piles are tightly fitted. The leveling of the seabed and the positioning frame ensure that the piles are installed neatly. The reinforcement and anti-corrosion sealing material can prevent pile corrosion, improve the stability of the piles, provide reliable support for the overall structure of the wharf, and extend the service life of the wharf.

[0013] Preferably, in step S3, during high tide, after the position sensor feedback signal controls the first motor to start, the speed of the first motor gradually increases from slow to fast, driving the bidirectional lead screw to rotate slowly, so that the slider drives the auxiliary floating dock to move smoothly towards the center of the main floating dock. During low tide, when the limit sleeve triggers the low position sensor, the first motor first brakes and pauses for 1-2 seconds, and then rotates in the opposite direction after the floating body stabilizes. The gradual change in motor speed and the braking pauses can prevent the auxiliary floating dock from moving too fast and causing a sudden change in the center of gravity of the floating body, preventing the floating body from swaying or tilting, and further improving the operational stability of the dock during high and low tide.

[0014] Preferably, in step S4, the braking of the second motor is synchronized with that of the first motor. During high tide, as the water level rises, the second motor drives the lead screw to rotate gradually, increasing the tilt angle of the baffle until it forms a 30-60 degree angle with the horizontal plane. As the water level drops, the second motor rotates in the opposite direction, gradually leveling the baffle to a horizontal state. At this time, the baffle can block underwater debris and also serve as an extension of the temporary work platform, facilitating workers to inspect and maintain the bottom of the floating body and the guide piles, thus improving the practicality and protective effect of the wharf. The synchronized braking of the second motor and the first motor enables coordinated action between the baffle and the auxiliary floating body wharf, precisely adapting to changes in tide level. The angle adjustment of the baffle can effectively protect the floating body while expanding the working space and improving the practicality of the wharf.

[0015] Compared with the prior art, the present invention provides a temporary wharf structure that adapts to rising and falling tides and its usage method, which has the following beneficial effects: This adaptive tidal temporary wharf structure and its usage method, through the addition of position sensors, allows for the downward movement of limiting sleeves when the main and auxiliary floating wharves sink during low tide. As the limiting sleeves move to different depths, the position sensors are simultaneously detected, controlling the activation of the first motor to rotate the bidirectional lead screw. This, in turn, causes the slider to synchronously extend the auxiliary floating wharves outwards. During high tide, the slider moves the auxiliary floating wharves on both sides of the main floating wharf towards the center, effectively lowering the overall center of gravity of the floating structure and offsetting the increased buoyancy caused by rising tide. This prevents the floating structure from swaying or tilting due to an excessively high center of gravity, ensuring stability for vessel berthing and personnel passage. During low tide, as the water level drops, the detection probe triggers the low-position sensors, controlling the auxiliary floating wharves to move outwards, expanding the overall support width of the floating structure and dispersing the force on the floating structure. This effectively prevents the floating structure from capsizing due to lower water levels and reduced buoyancy, adapting to stress changes at different tide levels and improving the usability of the temporary wharf structure.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: a temporary wharf structure that adapts to rising and falling tides and its usage method, comprising a shore-side platform 1, prestressed square piles 2, a fixed steel approach bridge 3, a movable steel approach bridge 4, a main floating wharf 5, a secondary floating wharf 6, a limiting sleeve 7, guide piles 8, a protective shell 9, a position sensor 10, a bearing seat 11, a bidirectional lead screw 12, a slider 13, a first motor 14, a gear 15, a guide rod 16, an insert plate 17, a hinged bracket 18, a swing arm 19, a hinged rod 20, 201, and a baffle; a second motor 21, a lead screw 22, a hinge joint 23, and a hinge lug 24. Please see Figure 1 and Figure 2 Fixed steel approach bridges 3 are installed at the top of both the shore-side foundation 1 and the prestressed square piles 2. Movable steel approach bridges 4 are hinged to the side of the top of the prestressed square piles 2. The outer end of the movable steel approach bridges 4 is hinged to the main floating dock 5. Please refer to [link / reference]. Figure 3 The main floating dock 5 is equipped with auxiliary floating docks 6 on both sides of its exterior. Please refer to [link / reference]. Figure 4 The lower surface of the main floating body wharf 5 is equipped with a limiting sleeve 7, and guide piles 8 are inserted inside the limiting sleeve 7. The prestressed square piles 2 and the guide piles 8 are driven into the seabed.

[0020] The protective shell 9 is installed on the outside of the main floating dock 5. Position sensors 10 are inserted into the inner sides of the guide piles 8. Detection probes are embedded in the inner wall of the limiting sleeve 7. Please refer to [link / reference]. Figure 5 The inner wall of the protective shell 9 is connected to a bearing seat 11, and a bidirectional lead screw 12 is inserted inside the bearing seat 11.

[0021] The slider 13 is screwed to both sides of the double-acting screw 12. The outer end of the slider 13 is connected to the surface of the auxiliary floating dock 6. The bottom of the inner cavity of the protective shell 9 is equipped with a first motor 14. Gears 15 are installed at corresponding positions on the outside of the first motor 14 and the double-acting screw 12.

[0022] Please see Figure 1 Guardrails are installed on the outer sides of the walking surfaces of the fixed steel approach bridge 3, the movable steel approach bridge 4, and the auxiliary floating dock 6. Anti-slip mats are also laid on the walking surfaces of these three structures. Please refer to [link / reference]. Figure 6Guide rods 16 are horizontally connected to both sides of the main floating dock 5. The guide rods 16 penetrate the interior of the auxiliary floating dock 6. Insert plates 17 are connected to both sides of the main floating dock 5 above the guide rods 16. The insert plates 17 are inserted into the interior of the auxiliary floating dock 6.

[0023] The threads on both sides of the bidirectional lead screw 12 are arranged in opposite directions. The middle part of the bidirectional lead screw 12 is connected to the inside of the bearing housing 11 through a ball bearing. Both ends of the bidirectional lead screw 12 pass through both sides of the protective shell 9. A sealing gasket is snapped into the penetration point between the bidirectional lead screw 12 and the protective shell 9. Through the added position sensor 10, when the main floating dock 5 and the auxiliary floating dock 6 sink due to low tide, the limiting sleeve 7 will be driven to press down. When the limiting sleeve 7 moves to different depths, it is detected synchronously by the position sensor 10, thereby controlling the start of the first motor 14 to drive the rotation of the bidirectional lead screw 12, which in turn causes the slider 13 to drive the auxiliary floating dock 6 to unfold outward synchronously. During high tide, the slider 13 moves the auxiliary floating docks 6 on both sides of the main floating dock 5 towards the center, effectively lowering the overall center of gravity of the floating body and offsetting the increase in buoyancy caused by the rising tide. This prevents the floating body from swaying or tilting due to an excessively high center of gravity, ensuring the stability of ships when docking and personnel when passing through. During low tide, the main floating dock 5 and the auxiliary floating docks 6 descend with the water level. The detection probe triggers the low-position sensor 10, controlling the auxiliary floating docks 6 to move outward, expanding the overall support width of the floating body and dispersing the force on the floating body. This effectively prevents the floating body from capsizing due to the decrease in water level and buoyancy, adapting to the force changes under different tide levels and improving the usability of the temporary dock structure.

[0024] Please see Figure 7 The side of the auxiliary floating dock 6 is connected to a hinge bracket 18. A swing arm 19 is inserted into the upper inner side of the hinge bracket 18. A hinge rod 20 is movably inserted into the lower inner side of the hinge bracket 18. A baffle 201 is connected to the outer end of the hinge rod 20. A lead screw 22 is screwed into the inside of the swing arm 19. A second motor 21 is mounted on the top of the swing arm 19 through a bracket. The rotor of the second motor 21 is coaxially connected to the lead screw 22. A hinge joint 23 is coaxially mounted on the outer end of the lead screw 22. A hinge ear 24 is movably connected to the outside of the hinge joint 23, and the outer end of the hinge ear 24 is connected to the surface of the baffle 201.

[0025] Please see Figure 8 A method for using an adaptive tidal temporary wharf structure, based on any of the above-mentioned adaptive tidal temporary wharf structures, includes the following steps: S1 construction deployment: First, prestressed square piles 2 and guide piles 8 are driven into the seabed. Then, a fixed steel approach bridge 3 is installed on the shore platform 1 and the top of the prestressed square piles 2. The movable steel approach bridge 4 is hinged to the side of the top of the prestressed square piles 2. Then, the outer end of the movable steel approach bridge 4 is hinged to the main floating dock 5. Before driving the prestressed square piles 2 and guide piles 8 into the seabed, the seabed in the construction area is leveled and sharp debris and protruding rocks are removed from the seabed surface. Then, the prestressed square piles 2 and guide piles 8 are positioned using a positioning frame to ensure that they are perpendicular to the seabed surface and the spacing is uniform. During the driving process, the verticality of the piles is monitored in real time. If tilting occurs, the driving angle is adjusted immediately. After driving is completed, the connection between the pile and the seabed is reinforced and filled with anti-corrosion sealing material to prevent seawater from seeping into the gap between the pile and the seabed and causing corrosion of the pile. At the same time, it is ensured that the connection surfaces of the fixed steel approach bridge 3, the shore platform 1, and the prestressed square piles 2 are tightly fitted. S2 component debugging: Check the installation status of the main floating dock 5, start the first motor 14 to adjust the transmission of gear 15 and the rotation performance of the bidirectional lead screw 12, and ensure that the slider 13 can drive the auxiliary floating dock 6 to move smoothly. S3 adaptive operation: After the dock is set up, when the tide rises, the main floating dock 5 and the auxiliary floating dock 6 rise with the water level, causing the limiting sleeve 7 to move upward along the guide pile 8. The limiting sleeve 7 triggers the position sensor 10 at the corresponding position inside the guide pile 8. The feedback signal of the position sensor 10 controls the first motor 14 to start, which drives the bidirectional lead screw 12 to rotate through the gear 15, causing the slider 13 to move the auxiliary floating dock 6 towards the center of the main floating dock 5, thus lowering the overall center of gravity. When the tide recedes, the main floating dock 5 and the secondary floating dock 6 descend with the water level. The limiting sleeve 7 triggers the low position sensor 10 inside the guide pile 8, which controls the first motor 14 to brake and rotate in the reverse direction, driving the bidirectional screw 12 to rotate in the reverse direction, so that the slider 13 pushes the secondary floating dock 6 to unfold outward and expand the support width. During high tide, the position sensor 10 feeds a signal to control the first motor 14 to start. The speed of the first motor 14 gradually increases from slow to fast, driving the bidirectional lead screw 12 to rotate slowly. This causes the slider 13 to drive the auxiliary floating dock 6 to move smoothly towards the center of the main floating dock 5. During low tide, when the limit sleeve 7 triggers the low position sensor 10, the first motor 14 first brakes and pauses for 1-2 seconds. After the floating body stabilizes, it rotates in the opposite direction. S4 auxiliary protection: According to the changes in tide level, the second motor 21 is started synchronously to drive the lead screw 22 to rotate. Through the hinge joint 23 and hinge lug 24, the baffle 201 is driven to rotate around the hinge rod 20. During low tide, the baffle 201 is in a horizontal state, and during high tide, the baffle 201 is in an upward tilting state, thus completing the entire process of the wharf's adaptive use of high and low tide. The braking of the second motor 21 is synchronized with that of the first motor 14. During high tide, as the water level rises, the second motor 21 drives the lead screw 22 to rotate gradually, causing the tilt angle of the baffle 201 to gradually increase until it forms an angle of 30-60 degrees with the horizontal plane. As the water level drops, the second motor 21 rotates in the opposite direction, causing the baffle 201 to gradually flatten to a horizontal state. At this time, the baffle 201 can block underwater debris and can also serve as an extension of the temporary working platform, making it convenient for staff to inspect and maintain the bottom of the floating body and the guide pile 8, thereby improving the practicality and protective effect of the wharf.

[0026] This solution incorporates position sensors 10. When the main floating dock 5 and the auxiliary floating dock 6 sink due to low tide, the limiting sleeve 7 is pushed down. This ensures that the position sensors 10 detect the movement of the limiting sleeve 7 to different depths, thereby controlling the activation of the first motor 14 to rotate the bidirectional lead screw 12. This, in turn, causes the slider 13 to synchronously extend the auxiliary floating dock 6 outwards. During high tide, the slider 13 moves the auxiliary floating docks 6 on both sides of the main floating dock 5 towards the center, effectively reducing the overall weight of the floating body. The center of gravity of the floating body counteracts the increased buoyancy caused by rising tides, preventing the floating body from swaying or tilting due to an excessively high center of gravity, thus ensuring stability when ships are docked and personnel pass through. During low tide, as the water level drops, the main floating dock 5 and the secondary floating dock 6 move outward, controlling the secondary floating dock 6 to expand the overall support width of the floating body, dispersing the force on the floating body, effectively preventing the floating body from capsizing due to lower water levels and reduced buoyancy. This adapts to the force changes under different tide levels, improving the usability of the temporary dock structure.

The feedback signal of the position sensor (10) controls the first motor (14) to start, which drives the bidirectional screw (12) to rotate through the gear (15), causing the slider (13) to move the secondary floating dock (6) towards the center of the main floating dock (5) and lower the overall center of gravity. When the tide recedes, the main floating dock (5) and the secondary floating dock (6) descend with the water level. The limiting sleeve (7) triggers the low position sensor (10) inside the guide pile (8), which controls the first motor (14) to brake and rotate in the opposite direction, driving the bidirectional screw (12) to rotate in the opposite direction, causing the slider (13) to push the secondary floating dock (6) to unfold outward and expand the support width. S4 auxiliary protection: According to the changes in tide level, the second motor (21) is started synchronously to drive the screw (22) to rotate. Through the hinge joint (23) and hinge ear (24), the baffle (201) is driven to rotate around the hinge rod (20). When the tide is low, the baffle (201) is in a horizontal state, and when the tide is high, the baffle (201) is in an upward tilting state, thus completing the full-process use of the wharf to adapt to the tide.

8. The method of using a temporary wharf structure with adaptive tidal flow according to claim 7, characterized in that: In step S1, before driving the prestressed square piles (2) and guide piles (8) into the seabed, the seabed in the construction area is leveled and the sharp debris and protruding rocks on the seabed surface are removed. Then, the prestressed square piles (2) and guide piles (8) are positioned using a positioning frame to ensure that they are perpendicular to the seabed surface and the spacing is uniform. During the driving process, the verticality of the pile is monitored in real time. If tilting occurs, the driving angle is adjusted immediately. After driving is completed, the connection between the pile and the seabed is reinforced and filled with anti-corrosion sealing material to prevent seawater from seeping into the gap between the pile and the seabed and causing the pile to corrode. At the same time, it is ensured that the connection surfaces of the fixed steel approach bridge (3) and the shore platform (1) and the prestressed square piles (2) are tightly fitted.

9. The method of using a temporary wharf structure with adaptive tidal currents according to claim 7, characterized in that: In step S3, during the high tide, the position sensor (10) feeds a signal to control the first motor (14) to start. The speed of the first motor (14) gradually increases from slow to fast, driving the bidirectional screw (12) to rotate slowly, so that the slider (13) drives the auxiliary floating dock (6) to move smoothly towards the center of the main floating dock (5). During the low tide, when the limit sleeve (7) triggers the low position sensor (10), the first motor (14) brakes and pauses for 1-2 seconds, and then rotates in the opposite direction after the floating body stabilizes.

10. The method of using a temporary wharf structure with adaptive tidal flow according to claim 7, characterized in that: In step S4, the braking of the second motor (21) is synchronized with that of the first motor (14). During high tide, as the water level rises, the second motor (21) drives the lead screw (22) to rotate gradually, causing the tilt angle of the baffle (201) to gradually increase until it forms an angle of 30-60 degrees with the horizontal plane. As the water level drops, the second motor (21) rotates in the opposite direction, causing the baffle (201) to gradually flatten to a horizontal state. At this time, the baffle (201) can block underwater debris and can also serve as an extension of the temporary working platform, making it convenient for staff to inspect and maintain the bottom of the floating body and the guide pile (8), thereby improving the practicality and protective effect of the wharf.
