Description

Technical Field

[0001] This invention relates to floating platform, specifically a marine floating platform device for transportation and hoisting. Background Technology

[0002] In the field of marine engineering construction, offshore floating platforms serve as core equipment for nearshore and offshore operations. They provide a stable working surface and transfer carrier for the transfer of marine materials, the hoisting of large components, and on-site construction operations at sea. They are widely applicable to various marine engineering operation scenarios such as offshore wind power development, port and wharf construction, and island and reef engineering construction.

[0003] Existing offshore floating platform hoisting and transfer operations mostly employ a split structure with a fixed hoisting base and independent transport tooling. Switching between hoisting and transfer operations requires repeated disassembly, assembly, and repositioning of the tooling fixtures or locking mechanisms. Adaptation processes for different operating conditions are cumbersome, process connections are time-consuming, and the platform's operational integration is low. The stability adjustment of existing floating platform systems largely relies on the water volume control of fixed ballast tanks within the platform body. With fixed lateral profiles and waterline area, changes in the platform's draft during tidal cycles cannot be simultaneously adjusted to optimize hydrodynamic characteristics and operational stability. This makes it difficult to balance maneuverability in narrow channels with stability under heavy loads, and the operational window is significantly limited by tidal variations, failing to meet the operational needs throughout the entire tidal cycle. Therefore, a new offshore floating platform transport and hoisting device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a marine floating pontoon transportation and hoisting platform device to solve the technical problems of low integration and coordination of the aforementioned processes and inability to adapt to the operational needs throughout the entire tidal cycle.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine floating pontoon transportation and hoisting platform device, comprising: The platform body, as well as the controller, hydraulic components and energy storage battery pack set in the inner cavity of the platform body, and the upper part of the platform body is equipped with a sliding rail, and a trolley is set on each sliding rail. The trolley is equipped with a hydraulic braking and locking mechanism, and the mounting surface of the trolley is respectively provided with a hydraulic locking interface and mounting hole, as well as a fully automatic twist lock fixing mechanism. The gantry crane is set directly above the main body of the platform via a hydraulic locking interface. The outriggers of the gantry crane are connected to the trolley, and a take-up and release roller is rotatably connected to the center of the gantry crane. The surface of the take-up and release roller is wrapped with a lifting rope, and a storage seat is connected to the bottom of the lifting rope. The watertight nested cavities are located on the sides of the main body of the platform. Each watertight nested cavity is equipped with a sealed stabilizing chamber. Hydraulic push rods adapted to hydraulic components are embedded in the inner wall of each watertight nested cavity. The telescopic ends of the hydraulic push rods are connected to the sealed stabilizing chambers. Collision-proof buffer fenders are provided on the outer edge of the watertight nested cavities. Adjustable ballast water tanks are provided inside the sealed stabilizing chambers.

[0006] Before operation, the controller receives operational information and requirements from the sea area. Through hydraulic components, it controls hydraulic push rods to execute corresponding actions, driving the sealed, stable hull to extend and retract along the watertight nested cavity. Simultaneously, it regulates the ballast state of the adjustable ballast water tanks inside the sealed, stable hull, completing the initial stability and draft adjustment of the platform's main body. At the same time, the controller uses hydraulic components to drive the trolley along the sliding track to the preset operating position, and uses a hydraulic braking locking mechanism to lock and secure the trolley.

[0007] Depending on the type of materials to be transferred and operational requirements, standardized transport units are secured using a fully automatic twist-lock fixing mechanism on the trolley, or construction equipment is installed and secured using mounting holes on the trolley. The controller, in conjunction with hydraulic components and an energy storage battery pack, drives the platform body to complete the transfer. During the transfer, the controller monitors the stability of the platform body in real time, dynamically adjusting the expansion and contraction of the sealed stability chamber and the ballast state of the internal adjustable ballast water tanks to ensure the stability and safety of the transfer process. During platform berthing operations, the anti-collision buffer fenders can buffer collision loads and avoid the risk of structural damage.

[0008] During hoisting operations, the trolley is released from its locking position. The trolley is then moved along the sliding track to adjust the working position of the gantry crane. Once in position, the hydraulic braking locking mechanism secures the trolley to the gantry crane. The controller drives the take-up and release rollers to rotate, adjusting the vertical position of the loading platform via the hoisting ropes. This completes the lifting, relocation, and installation of the components to be hoisted. During the operation, the controller simultaneously regulates the working status of the sealed, stable cabin to maintain the levelness and operational stability of the platform.

[0009] During operation, the controller adjusts the extension and retraction of the sealed stable hull and the ballast volume of the internal adjustable ballast water tanks in real time according to the changes in sea level due to tides, adapting to the operational and relocation requirements under different water levels. After the operation is completed, the controller drives all actuators to reset, releases all locking mechanisms, and completes the relocation and storage of the platform body.

[0010] Preferably, the watertight nested cavities around the sides of the platform body are symmetrically designed, and the surface of the sealed stability chamber slides and fits against the inner wall of the watertight nested cavity.

[0011] When the controller drives the hydraulic push rod to act through the hydraulic component, the sealed stability cabin in the symmetrically designed watertight nested cavity synchronously executes the telescopic action, and the sealed stability cabin slides smoothly along the inner wall of the watertight nested cavity to complete the stability adjustment operation of the platform main body.

[0012] Preferably, concave watertight accommodation cabins are uniformly arranged at both ends of the bottom of the platform main body, and the adjacent concave watertight accommodation cabins at the same end are symmetrically designed.

[0013] Before the platform main body performs the shifting operation, the controller controls the matching opening and closing mechanism of the concave watertight accommodation cabin according to the operation conditions to provide conditions for the operation of the internal propulsion component. The symmetrically designed concave watertight accommodation cabin can ensure the balanced force during the operation of the internal propulsion component.

[0014] Preferably, a fully rotatable azimuth thruster assembly is arranged in the inner cavity of each concave watertight accommodation cabin, and the fully rotatable azimuth thruster assembly is installed in the concave watertight accommodation cabin through a hydraulic swing arm.

[0015] When the platform main body performs the shifting operation, the controller drives the hydraulic swing arm to act through the hydraulic component,带动 the fully rotatable azimuth thruster assembly to move out of the concave watertight accommodation cabin to the operation position, and the controller drives the fully rotatable azimuth thruster assembly to operate to provide propulsion force and steering torque for the platform main body. After the operation is completed, the fully rotatable azimuth thruster assembly is driven back into the concave watertight accommodation cabin by the hydraulic swing arm.

[0016] Preferably, the fully rotatable azimuth thruster assembly is equipped with a permanent magnet synchronous bidirectional motor, and a watertight hatch is rotatably connected to the inlet and outlet ends of the concave watertight accommodation cabin.

[0017] When the fully rotatable azimuth thruster assembly performs the operation action, the controller first drives the watertight hatch to open, then moves the fully rotatable azimuth thruster assembly out through the hydraulic swing arm, and drives the fully rotatable azimuth thruster assembly to complete the propulsion and steering operations through the permanent magnet synchronous bidirectional motor. After the fully rotatable azimuth thruster assembly is retracted into the concave watertight accommodation cabin, the controller drives the watertight hatch to close to complete the watertight sealing of the concave watertight accommodation cabin.

[0018] Preferably, the permanent magnet synchronous bidirectional motor supporting the fully rotatable azimuth thruster assembly is connected to the energy storage battery pack in the inner cavity of the platform main body.

[0019] When the platform main body performs the towage or self-propelled shifting operation, the permanent magnet synchronous bidirectional motor can convert kinetic energy into electric energy through reverse power generation under surplus working conditions and transport it to the energy storage battery pack for storage. When the platform main body is in the station-keeping operation or under low-load working conditions, the energy storage battery pack can supply power to the permanent magnet synchronous bidirectional motor and other electrical equipment of the platform to complete the energy allocation and utilization.

[0020] Preferably, watertight guide sleeves are installed at the top four corners of the platform body, and the bottom end of the watertight guide sleeve extends downward through the top of the platform body.

[0021] Before the platform body is positioned, the controller drives the matching lifting mechanism to move the leg structure vertically along the inner cavity of the watertight guide sleeve, allowing the leg structure to be inserted into the seabed to fix the platform body in place. When the platform body is moved, the leg structure is moved back to the preset position along the watertight guide sleeve, releasing the platform's positioning constraints.

[0022] Preferably, the inner cavity of the watertight guide sleeve is equipped with a hydraulic pin-type pile leg that can be raised and lowered vertically, and the hydraulic pin-type pile leg is equipped with a graded load-adjusting hydraulic cylinder.

[0023] During platform positioning operations, the controller drives the staged load-adjusting hydraulic cylinders via hydraulic components, causing the hydraulic pin-type legs to descend vertically along the watertight guide sleeve, inserting them into the seabed. The staged load-adjusting hydraulic cylinders then distribute the load among the hydraulic pin-type legs and adjust the platform elevation. After the operation is completed, the staged load-adjusting hydraulic cylinders retract the hydraulic pin-type legs vertically, releasing the platform from positioning.

[0024] Preferably, the graded load-adjusting hydraulic cylinder is mounted on the top perimeter of the platform body via a mounting base, and watertight sealing components are provided at both the top and bottom of the watertight guide sleeve.

[0025] During the lifting and lowering operation of the hydraulic pin-type pile leg driven by the staged load-adjusting hydraulic cylinder along the watertight guide sleeve, the watertight sealing components at the top and bottom of the watertight guide sleeve remain in contact with the surface of the hydraulic pin-type pile leg, achieving dynamic watertight sealing during the lifting and lowering process. The staged load-adjusting hydraulic cylinder stably transmits the working load through the mounting base, completing the lifting and lowering and load-adjusting operations of the pile leg.

[0026] Preferably, the inner wall of the watertight guide sleeve is uniformly provided with an annular buffer pad layer and a hydraulic clamping and locking assembly from top to bottom.

[0027] After the hydraulic pin-type pile leg completes its lifting and lowering operation along the watertight guide sleeve, the controller drives the hydraulic clamping and locking assembly to radially clamp and lock the hydraulic pin-type pile leg, thus fixing its position. During the lifting and lowering process of the hydraulic pin-type pile leg, the annular buffer pad can buffer the lateral collision load between the pile leg and the sleeve, ensuring the smoothness of the lifting and lowering operation.

[0028] Compared with the prior art, the present invention provides a marine floating box transportation and hoisting platform device, which has the following beneficial effects: This offshore floating pontoon transport and hoisting platform, through the structural design of the parallel sliding rails installed on the upper part of the platform body and the matching trolley, combined with the hydraulic locking interface, installation holes, fully automatic twist lock fixing mechanism and hydraulic braking locking mechanism integrated on the trolley, can achieve rapid adaptation without disassembly for multiple working conditions such as hoisting, transportation and construction, which greatly improves the integration level of platform operations and the efficiency of process connection.

[0029] Through the built-in design of watertight nested cavities on all four sides of the platform's main body, combined with a sealed and stable chamber driven by hydraulic push rods adapted to the hydraulic components, the platform's lateral profile and waterline area can be flexibly adjusted to meet the operational needs throughout the entire tidal cycle, balancing the platform's maneuverability and operational stability.

[0030] By using the fixed connection structure between the gantry crane outriggers and the trolley via the hydraulic locking interface, combined with the lifting structure of the gantry crane's take-up and release rollers, lifting ropes, and bottom placement seat, and the trolley's full-stroke sliding along the sliding track and the hydraulic braking locking mechanism locking at any position, the entire platform can be covered without blind spots during lifting operations, greatly improving the coverage and accuracy of lifting operations.

[0033] 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.

[0034] This invention provides a technical solution: a marine floating pontoon transportation and hoisting platform device, comprising: (See attached diagram) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The platform body 1, and the controller, hydraulic components and energy storage battery pack are set in the inner cavity of the platform body 1. The upper part of the platform body 1 is equipped with a sliding rail 2, and a trolley 3 is set on each sliding rail 2. The trolley 3 is equipped with a hydraulic braking locking mechanism, and a hydraulic locking interface and mounting hole are respectively opened on the mounting surface of the trolley 3, as well as a fully automatic twist lock fixing mechanism. The gantry crane 4 is set directly above the platform body 1 through a hydraulic locking interface. The outriggers of the gantry crane 4 are connected to the trolley 3, and a take-up roller 5 is rotatably connected to the center of the gantry crane 4. The surface of the take-up roller 5 is wrapped with a lifting rope 6, and a storage seat 7 is connected to the bottom end of the lifting rope 6. Watertight nested cavities 8 are opened on all four sides of the platform body 1. Each watertight nested cavity 8 is equipped with a sealed stabilizing chamber 9. Hydraulic push rods 10 adapted to hydraulic components are embedded in the inner wall of each watertight nested cavity 8. The telescopic end of the hydraulic push rod 10 is connected to the sealed stabilizing chamber 9. Collision-proof buffer fenders 11 are provided on the outer edge of the watertight nested cavity 8. An adjustable ballast water tank is provided inside the sealed stabilizing chamber 9.

[0035] By integrating hydraulic locking interfaces, mounting holes, and fully automatic twist lock fixing mechanisms into the trolley 3, and cooperating with the sliding rail 2, the working position of the gantry crane 4 can be flexibly adjusted. At the same time, it can seamlessly adapt to the needs of multiple scenarios such as material transportation, equipment installation and fixing, and hoisting operations, without the need for additional equipment disassembly and structural modification. This greatly improves the integration level of the platform device and the efficiency of construction operations, meeting the usage requirements of multi-process collaborative operations in marine engineering.

[0036] With the retractable and adjustable sealed stabilizing hull 9 and the internal adjustable ballast water tank, the waterline area and stability parameters of the platform body 1 can be dynamically adjusted according to the sea conditions and tide level changes. When operating in deep water, the sealed stabilizing hull 9 can be extended to improve the anti-overturning ability and load-bearing capacity of the platform body 1. When operating in shallow water, the sealed stabilizing hull 9 can be retracted to reduce the platform's draft and profile size. This not only ensures the stability and safety of operations throughout the entire tide cycle, but also improves the platform's mobility and environmental adaptability in complex marine environments.

[0037] By controlling the hydraulic components and various actuators in a unified manner through the controller, the entire process of platform stability adjustment, positioning adjustment and hoisting operation can be coordinated and controlled. In conjunction with the energy storage battery pack, the energy of the device can be rationally allocated and utilized, reducing energy consumption and pollutant emissions during operation. At the same time, the anti-collision buffer fender 11 can effectively avoid structural collision damage during platform berthing and operation, thereby improving the service life of the device and operational safety.

[0038] Please see Figure 2 and Figure 3 The watertight nested cavities 8 on the sides of the platform body 1 are symmetrically designed, and the surface of the sealed stability chamber 9 slides and fits against the inner wall of the watertight nested cavity 8.

[0039] The symmetrical design of the watertight nested cavities 8 ensures uniform force distribution on the platform body 1 during the extension and retraction of each sealed stability chamber 9, avoiding platform tilting caused by unilateral load shifts and improving the accuracy and reliability of stability adjustment. The sliding fit design between the sealed stability chamber 9 and the inner wall of the watertight nested cavities 8 ensures watertight performance during extension and retraction, avoiding the risk of seawater seeping into the cavity, while also improving the smoothness of the extension and retraction of the sealed stability chamber 9 and preventing jamming malfunctions.

[0040] Please see Figure 4 The bottom of the platform body 1 is evenly provided with concave watertight accommodating chambers 12 at both ends, and the concave watertight accommodating chambers 12 adjacent to each other at the same end are symmetrically designed.

[0041] The concave watertight compartment 12 provides a protective installation space for the propulsion components without altering the overall shape of the platform body 1, preventing corrosion and impact damage caused by direct exposure of the propulsion components to the marine environment. The symmetrical design of the concave watertight compartment 12 at the same end ensures a uniform distribution of propulsion force on the platform body 1 during operation of the internal propulsion components, avoiding yaw moments and improving the maneuverability and stability of the platform body 1 during relocation operations.

[0042] The inner cavity of the concave watertight containment chamber 12 is equipped with a fully azimuth propeller assembly 14, and the fully azimuth propeller assembly 14 is installed in the concave watertight containment chamber 12 via a hydraulic swing arm.

[0043] The azimuth propeller assembly 14 is retractable and deployable via a hydraulically operated swing arm, adapting to operational needs at different water levels during high and low tides. In shallow water, the azimuth propeller assembly 14 can be retracted into the recessed watertight compartment 12 to prevent damage from bottoming out. In deep water, it can be deployed to maintain propulsion efficiency. The azimuth propeller assembly 14 enables flexible omnidirectional movement and precise positioning of the platform body 1, significantly improving the platform's mobility and operational adaptability in complex marine environments.

[0044] The azimuth propeller assembly 14 is equipped with a permanent magnet synchronous bidirectional motor, and the inlet and outlet ends of the recessed watertight containment chamber 12 are rotatably connected to a watertight door 13.

[0045] The permanent magnet synchronous bidirectional motor enables efficient forward and reverse drive of the azimuth propeller assembly 14, balancing propulsion performance and control precision, and enhancing the operational flexibility of platform relocation. The watertight hatch 13, after the azimuth propeller assembly 14 is retracted, completes the watertight sealing of the recessed watertight compartment 12, preventing seawater and sediment from entering the compartment and avoiding corrosion and sediment buildup on internal components, thus extending equipment lifespan and ensuring operational reliability.

[0046] The permanent magnet synchronous bidirectional motor of the azimuth propeller assembly 14 is connected to the energy storage battery pack inside the main body 1 of the platform.

[0047] The integrated design of the permanent magnet synchronous bidirectional motor and the energy storage battery pack enables the recovery and reuse of excess energy during platform operations, significantly reducing fuel consumption and pollutant emissions, thus meeting energy-saving and environmentally friendly design requirements. Simultaneously, the energy storage battery pack can serve as a backup power source, providing emergency power to the azimuth propeller assembly 14, enhancing the platform's safety and redundancy in complex marine environments.

[0048] Please see Figure 6 Watertight guide sleeves 15 are installed at the four corners of the top of the platform body 1, and the bottom end of the watertight guide sleeves 15 extends downward through the top of the platform body 1.

[0049] The watertight guide sleeve 15, with its through-type design, provides precise vertical guidance for the lifting and lowering of the pile legs, preventing deviation and jamming during the lifting process and ensuring the verticality and accuracy of the pile leg operations. Simultaneously, the watertight guide sleeve 15 isolates seawater from the inner cavity of the platform body 1, ensuring the watertight performance and buoyancy reserve of the platform body 1 and preventing safety hazards caused by seawater seepage into the platform's inner cavity. The symmetrical arrangement at the four corners ensures uniform stress distribution during platform positioning and fixation, improving the stability of platform operations.

[0050] The inner cavity of the watertight guide sleeve 15 is equipped with a hydraulic pin-type pile leg 16 that can be raised and lowered vertically, and the hydraulic pin-type pile leg 16 is equipped with a graded load-adjusting hydraulic cylinder 17.

[0051] The hydraulic pin-type legs 16, in conjunction with the graded load-adjusting hydraulic cylinders 17, enable stable fixation of the platform body 1 during operation, effectively resisting the impact of wave and tidal loads on the platform and significantly improving the stability and load-bearing capacity of the platform during hoisting operations. The graded load-adjusting hydraulic cylinders 17 can adjust the load distribution of each hydraulic pin-type leg 16 and the platform's horizontal elevation in real time according to the working conditions and tidal changes, adapting to the operational needs throughout the entire tidal cycle and ensuring that the platform remains in a stable operating state at all times.

[0052] The graded load adjustment hydraulic cylinder 17 is mounted on the top perimeter of the platform body 1 via a mounting base, and watertight sealing components are provided at both the top and bottom of the watertight guide sleeve 15.

[0053] The graded load-adjusting hydraulic cylinder 17 is installed via a mounting base on the top of the platform, ensuring that the load is directly transmitted to the main load-bearing structure of the platform body 1 during cylinder operation, thus improving the stability of load transmission and structural reliability. The watertight sealing components at both ends of the watertight guide sleeve 15 achieve dynamic watertight sealing throughout the entire lifting and lowering process of the hydraulic pin-type legs 16, effectively preventing seawater and sediment from entering the watertight guide sleeve 15 and the platform's inner cavity. This avoids platform buoyancy loss and equipment corrosion problems caused by seal failure, improving the safety of platform operation and extending equipment lifespan.

[0054] The inner wall of the watertight guide sleeve 15 is uniformly provided with annular buffer pads and hydraulic clamping and locking components from top to bottom.

[0055] The hydraulic clamping and locking assembly reliably locks the hydraulically driven leg 16 radially after it has reached its designated position, evenly distributing the load to the platform body 1 and preventing slippage and swaying. This significantly improves the stability and safety of the platform during positioning. The annular buffer layer effectively cushions the impact and vibration between the leg and the inner wall of the casing during leg raising and lowering, reducing structural wear and noise. It also prevents jamming during leg raising and lowering, enhancing the smoothness and service life of the leg.

[0056] This solution: Before the operation starts, the controller has a built-in working condition information acquisition and processing module. This module is used to receive and parse the tide level information, sea state information, operation task requirements and preset operation parameters of the operation sea area, and simultaneously collect sensor data on the attitude, liquid level and equipment operating status of the main body of the platform 1, and complete the initialization self-check and operation parameter verification of the entire platform system. The controller also has a built-in system coordination control module. This module is used to coordinate the action sequence of all actuators of the platform, plan the action logic of the entire process operation, avoid action conflicts between actuators, and issue corresponding operation instructions to each subordinate control module.

[0057] The controller has a built-in hydraulic system drive module. This module receives control commands from the system coordination control module and outputs corresponding drive signals to the hydraulic components inside the platform body 1, controlling each hydraulic actuator to complete the corresponding action. The hydraulic system drive module drives the hydraulic push rod 10 through the hydraulic components to perform the corresponding action, driving the sealed stabilizing chamber 9 to slide smoothly along the inner wall of the watertight nested cavity 8 symmetrically designed around the side of the platform body 1, completing the extension and retraction adjustment, and synchronously controlling the ballast state of the adjustable ballast water tank inside the sealed stabilizing chamber 9, completing the initial stability and draft adjustment of the platform body 1. At the same time, the hydraulic system drive module drives the trolley 3 through the hydraulic components to slide along the sliding track 2 installed parallel to the upper part of the platform body 1 to the preset working position, and completes the locking and fixing of the trolley 3 through the hydraulic braking locking mechanism.

[0058] Before the platform body 1 performs the relocation operation, the system coordination control module sends a relocation preparation command to the hydraulic system drive module. The hydraulic system drive module drives the watertight door 13 at the entrance and exit of the concave watertight containment chamber 12 to open, and then drives the hydraulic swing arm through the hydraulic components to move the azimuth propeller assembly 14 from the concave watertight containment chamber 12 at both ends of the bottom of the platform body 1 to the working position. The controller has a built-in energy management module, which is used to coordinate the charging and discharging of the energy storage battery pack in the cavity of the platform body 1, coordinate the energy distribution of various electrical equipment on the platform, complete the recovery and storage of surplus energy during the operation and the energy guarantee in emergency conditions. The energy management module allocates the corresponding drive energy to the permanent magnet synchronous bidirectional motor matched with the azimuth propeller assembly 14.

[0059] When the platform body 1 performs self-propelled relocation operations, the system collaborative control module drives the permanent magnet synchronous bidirectional motor through the energy management module, which in turn drives the azimuth propeller assembly 14 to provide propulsion and steering torque for the platform body 1, completing the relocation and precise positioning of the platform body 1. The controller has a built-in platform stability real-time control module, which calculates and outputs stability adjustment commands in real time based on the platform attitude data, sea state data, and tide level change data obtained by the working condition information acquisition and processing module. It dynamically adjusts the buoyancy and stability parameters of the platform body 1. During the relocation process, the platform stability real-time control module monitors the stability status of the platform body 1 in real time and dynamically adjusts the extension and retraction of the sealed stability compartment 9 and the ballast status of the internal adjustable ballast water tank through the hydraulic system drive module to ensure the stability of the relocation process. During the relocation operation, the permanent magnet synchronous bidirectional motor converts kinetic energy into electrical energy through reverse power generation under surplus working conditions. The energy management module sends the recovered electrical energy to the energy storage battery pack for storage.

[0060] After the platform body 1 arrives at the operating sea area, the system coordination control module issues a positioning and fixing command. The hydraulic system drive module drives the staged load adjustment hydraulic cylinder 17 through the hydraulic components, causing the hydraulic pin-type legs 16 to descend vertically along the inner cavity of the watertight guide sleeve 15 installed around the top of the platform body 1. The annular buffer layer on the inner wall of the watertight guide sleeve 15 buffers the lateral load during the lifting and lowering process of the hydraulic pin-type legs 16, allowing the hydraulic pin-type legs 16 to insert into the seabed. The staged load adjustment hydraulic cylinder 17 completes the various hydraulic operations. The load distribution of the pin-type pile leg 16 and the elevation adjustment of the platform body 1; after the hydraulic pin-type pile leg 16 is in place, the hydraulic system drive module drives the hydraulic clamping and locking component on the inner wall of the watertight guide sleeve 15 to perform radial clamping and locking of the hydraulic pin-type pile leg 16, thus fixing the position of the pile leg; during the lifting and lowering operation of the hydraulic pin-type pile leg 16, the watertight sealing components at the top and bottom of the watertight guide sleeve 15 are always in contact with the surface of the hydraulic pin-type pile leg 16, thus completing the dynamic watertight seal during the lifting and lowering process.

[0061] After the platform body 1 is fixed in place, the standardized transport unit is locked by the fully automatic twist lock fixing mechanism on the mounting surface of the trolley 3, according to the type of material to be transferred and the operation requirements, or the engineering construction equipment is installed and fixed by the mounting holes on the mounting surface of the trolley 3. During the berthing operation, the anti-collision buffer fender 11 on the outer edge of the watertight nested cavity 8 buffers the collision load during the berthing process. If it is necessary to adjust the operation point during the operation, the locking state of the hydraulic brake locking mechanism of the trolley 3 is released, and the trolley 3 slides along the sliding track 2 to the target operation position. After it is in place, the trolley 3 is locked and fixed again by the hydraulic brake locking mechanism.

[0062] When carrying out hoisting operations, the locking state of the hydraulic brake locking mechanism of the trolley 3 is released. The working position of the gantry crane 4 is adjusted by the trolley 3 along the sliding track 2. The assembly and fixation of the gantry crane 4 and the trolley 3 are completed through the hydraulic locking interface on the mounting surface of the trolley 3. After being in place, the position of the trolley 3 and the gantry crane 4 is locked by the hydraulic brake locking mechanism. The system coordination control module issues hoisting operation commands, drives the take-up roller 5 in the center of the gantry crane 4 to rotate, and adjusts the vertical position of the placement seat 7 connected to the bottom end of the hoisting rope 6 by the hoisting rope 6 wound on the surface of the take-up roller 5, thus completing the hoisting, relocation and installation of the component to be hoisted.

[0063] Throughout the entire operation cycle, the working condition information acquisition and processing module collects real-time data on the changes in sea level due to tides, the attitude data of the platform body 1, and the load change data. Based on the collected real-time data, the platform stability real-time control module adjusts the extension and retraction state of the sealed stability chamber 9 and the ballast volume of the internal adjustable ballast water tank in real time through the hydraulic system drive module. Simultaneously, the load distribution of each hydraulic pin-type leg 16 is dynamically adjusted through the graded load adjustment hydraulic cylinder 17 to adapt to the operational requirements under different water levels and different operating loads, maintaining the levelness and operational stability of the platform body 1. The controller has a built-in safety monitoring and emergency control module, which is used to monitor the operating status, structural load, and watertight performance of all equipment on the platform in real time. When abnormal working conditions occur, the corresponding emergency protection action is triggered to ensure the safety of the platform and the operation.

[0064] After the operation is completed, the system collaborative control module issues a reset command, drives the take-up and release roller 5 to rotate, and drives the placement seat 7 to reset to the initial position through the hoisting rope 6. The locking state of the hydraulic braking locking mechanism of the trolley 3 is released, and the trolley 3 is driven to reset to the initial position along the sliding track 2 and complete the locking. At the same time, the clamping and locking state of the hydraulic clamping locking component on the inner wall of the watertight guide sleeve 15 is released. The hydraulic pin-type pile leg 16 is driven to rise vertically along the watertight guide sleeve 15 and retract to the preset position through the graded load adjustment hydraulic cylinder 17, and the stationary fixation of the platform body 1 is released.

[0065] After the platform body 1 is released from its fixed position, the system coordination control module issues a relocation and departure command, which drives the platform body 1 to relocate and leave the site via the azimuth propeller assembly 14. After leaving the site, the hydraulic swing arm drives the azimuth propeller assembly 14 to retract into the concave watertight containment chamber 12, driving the watertight door 13 to close, thus completing the watertight sealing of the concave watertight containment chamber 12. Simultaneously, the hydraulic push rod 10 drives the sealed stabilizing chamber 9 to retract into the watertight nested cavity 8, completing the state reset and storage of the platform body 1. The energy management module completes the energy replenishment and status maintenance of the energy storage battery pack, and the safety monitoring and emergency control module completes the operation status inspection and anomaly recording of the entire system, completing the entire process operation.
