Description

Technical Field

[0001] This invention relates to the field of special equipment technology for marine engineering, and more specifically, to a modular deep-sea floating dock. Background Technology

[0002] With the increasing intensity of marine development and the rising demands of national defense, higher requirements are being placed on the repair and maintenance of marine equipment. Floating docks, as crucial facilities for marine equipment repair, play a key role in the field of marine engineering. However, traditional floating docks have many limitations, making it difficult to meet the operational needs of complex deep-sea environments and the strategic requirements of military-civilian integration.

[0003] Traditional floating docks, limited by structural strength, struggle to maintain stable operation in complex deep-sea conditions, posing significant safety risks. Their propulsion systems are ill-suited to the energy demands of deep-sea operations, and their positioning technology lacks precision, making accurate berthing in deep-sea areas difficult and hindering the smooth execution of maintenance work. Furthermore, the functions of traditional floating docks are relatively fixed; when switching from civilian vessel maintenance to wartime emergency repair of naval vessels, rapid functional module adjustments are difficult, resulting in a lack of flexibility and an inability to respond promptly to different mission requirements. In addition, conventional floating docks have long construction cycles and cannot be quickly deployed in emergencies, failing to meet the urgent needs of emergency repairs of marine equipment.

[0004] To address the problems of traditional floating docks, this invention proposes a modular deep-sea floating dock based on military-civilian integration for emergency repair and routine maintenance of marine equipment. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a modular deep-sea floating dock to enhance the flexibility of floating dock use, realize the dual military and civilian use of floating dock, reliable deep-sea operation and rapid deployment, and provide core technical support for the deep-sea equipment support system.

[0033] The suction pile system has one end detachably connected to the other end of the anchor chain; and

[0034] A high-holding-force anchor is installed at the other end of the suction pile system; after the floating dock arrives at the operating sea area, the anchor chain is lowered and anchored into the seabed rock layer through the suction pile system and the high-holding-force anchor for mooring.

[0056] (1) The floating dock of the present invention adopts a military-civilian integrated modular architecture mode, and constructs an interchangeable military-civilian general functional module library and a military reinforcement module library; wherein the main body of the floating dock, the maintenance operation module, the power module, the energy module and the life support module constitute the military-civilian general functional module library of the floating dock, and the cover plate shielding module and the explosion-proof deck module constitute the military reinforcement module library of the floating dock; by constructing an interchangeable military-civilian general functional module library and a military reinforcement module library, the rapid replacement and combination of different functions of the floating dock is realized, the operational flexibility of the floating dock is improved, and it can meet the flexible needs of the marine equipment maintenance system under the military-civilian integration development strategy; at the same time, the interface and modification space of the military reinforcement module library are reserved on the main body of the floating dock, which facilitates the flexible conversion between civilian and military functions of the floating dock and improves the comprehensive utilization value of the floating dock.

[0093] like Figure 1As shown, an embodiment of the present invention provides a modular deep-sea floating dock, which may specifically include a floating dock body 13, a maintenance operation module 1, a cover plate shielding module 7, an explosion-proof deck module, and a pile anchor module 9. Here, the floating dock body 13, the maintenance operation module 1, the power module, the energy module 4, and the living support module 6 (the power module, energy module 4, and living support module 6 will be described in further detail below) constitute a military-civilian universal functional module library for the floating dock. The cover plate shielding module 7 and the explosion-proof deck module constitute a military reinforcement module library for the floating dock. The military reinforcement module library and the military-civilian universal functional module have compatible interfaces and can be quickly interchanged. Preferably, interfaces and modification space for each piece of equipment in the military reinforcement module can be reserved on the military-civilian universal functional module to realize flexible and rapid conversion between civilian and military functions of the floating dock, meet the needs of ocean-going emergency repair and routine maintenance of marine equipment such as military ships and civilian vessels, and thus enhance the comprehensive utilization value of the floating dock.

[0094] The floating dock body 13 comprises multiple box-shaped modules 131, which are detachably connected to form the floating dock body 13. Here, the box-shaped modules 131 can be standardized, and these standardized modules can be manufactured using a new type of aluminum alloy-carbon fiber composite high-strength lightweight alloy material, balancing high strength and lightweight characteristics. Preferably, the standardized box-shaped modules can be uniformly set to a length of 18m × width of 8m × height of 6m, adaptable to various transportation methods such as road flatbed trucks, railway container wagons, and sea-going deck transport vessels. Each module weighs less than or equal to 30 tons, allowing for helicopter hoisting and transfer, significantly improving transportation and deployment flexibility.

[0095] Multiple box-shaped modules 131 can be assembled by an automated hoisting robot with assisted positioning and a modular large floating crane according to a preset process to form a floating dock body 13 capable of repairing ships of 10,000 tons. The unmanned assembly process of the box-shaped modules 131 is shortened by more than 50% compared with traditional floating docks, which can significantly reduce on-site assembly time, realize the rapid assembly of the floating dock and the rapid formation of maintenance capabilities, solve the problem of long construction cycle of traditional floating docks, improve the rapid deployment capability of floating docks, and can respond to the emergency maintenance needs of marine equipment in a timely manner.

[0096] The maintenance module 1 is fixed to the inner side of the dock walls on both sides of the floating dock body 13 and can be rotated and tilted on the inner plane of the dock walls. Here, the maintenance module 1 can be a mechanical maintenance arm installed on the inner side of the dock walls, which can achieve 360-degree horizontal rotation and ±45-degree tilt adjustment on the inner plane of the dock walls to cover a large area of ​​the dock's working space. It can be aligned with different maintenance points without moving the floating dock, thereby meeting the task requirements of different maintenance operations within the floating dock. In this invention, the number of mechanical maintenance arms installed is specifically determined by the length and width of the floating dock in actual application, and this invention does not impose a specific limitation.

[0097] The cover plate shielding module 7 is slidably connected to the top of the dock wall. During maintenance work in the floating dock, the cover plate shielding module 7 slides along the top of the dock wall and unfolds to form a shielding space covering the main body of the floating dock, used to shield against external signal interference. Here, the cover plate shielding module 7 can be an electromagnetic shielding module. The cover plate shielding module 7 can be smoothly folded or unfolded along the slide rail 71 on the top of the dock wall on both sides of the main body of the floating dock 13. When unfolded, it can form a semi-enclosed electromagnetic shielding space above the dock wall. This electromagnetic shielding space covers the main body of the floating dock 13 and other modules within it, so as to shield against external signal interference during maintenance of the floating dock and ensure data security and normal operation of equipment during the maintenance process of military equipment.

[0098] Here, the shielding structure and sliding operation design of the cover plate shielding module 7 can not only ensure that the core data of military equipment maintenance in the floating dock is not stolen or tampered with, but also avoid problems such as program disorder and data loss caused by external electromagnetic interference during equipment maintenance, thus providing a safe and stable electromagnetic environment for military equipment maintenance.

[0099] The explosion-proof deck module is installed on the outside of the dock wall and detachably connected to it, used to protect the floating dock deck during wartime. Here, the explosion-proof deck module is laid on the outside of the dock wall. This module can be prefabricated and installed on the pre-reserved connection position on the outside of the dock wall using a robotic arm or large hoisting equipment. This enhances the structural strength and buffering capacity of the floating dock body 1, providing rapid wartime protection for the floating dock and preventing damage to the internal structure (such as the deck) and equipment from external explosive loads. This fundamentally protects the safety of maintenance equipment and personnel inside the floating dock, ensuring the continuity of wartime maintenance operations.

[0100] The anchor modules 9 are symmetrically arranged on both sides of the bottom of the floating dock body 13, and one end of the anchor module 9 is fixedly connected to the bottom of the floating dock body 13. After the floating dock arrives at the operating sea area, it is lowered and anchored into the seabed rock layer through the anchor modules 9 for mooring. Preferably, the anchor modules 9 are retractable anchor modules, which can still provide reliable mooring force in water depths exceeding 100 meters, meeting the needs of deep-sea (water depth greater than 100 meters) operating waters and ensuring the stable mooring of the floating dock under complex geological conditions in the deep sea.

[0101] The floating dock provided in the above embodiments can achieve rapid function switching through interchangeable military and civilian functional module libraries and military reinforcement module libraries; by adopting pile anchor modules, it can achieve stable berthing in 100-meter deep water, ensuring stability in complex deep-sea conditions; at the same time, the modular floating dock body can achieve unmanned rapid assembly, shortening assembly time, thereby enabling the floating dock to meet the needs of marine equipment such as military ships and civilian vessels for long-range emergency repair and routine maintenance, taking into account both military and civilian use and deep-sea operation capabilities, improving the flexibility of use and maintenance efficiency.

[0102] See Figure 2 and Figure 3 In an optional embodiment of the present invention, two adjacent box-type modules 131 among the plurality of box-type modules 131 are detachably connected by a first connecting unit. Here, the first connecting unit may be a prestressed-electromagnetic hydraulic connector. Each box-type module 131 is locked and fixed by the prestressed-electromagnetic hydraulic connector. Preferably, the connection part may be sealed with sealant to ensure water tightness.

[0103] Continue reading Figure 2 and Figure 3 The first connecting unit may specifically include an upper docking support 141, a lower connecting base 142, a prestressed hydraulic fastener 146, and a first positioning magnetic ring 144. The upper docking support 141 is fixedly connected to one of the two adjacent box-shaped modules 131 on one side, and a fixing anchor claw 143 is provided on the other side of the upper docking support 141. The lower connecting base 142 is fixedly connected to the other of the two adjacent box-shaped modules on one side, and the other side of the lower connecting base 142 is opposite to the upper docking support 141.

[0104] A prestressed hydraulic clamp 146 is disposed on the other side of the lower connecting base 142 and is used to provide prestress and connect and fix the anchor claw 143. A first positioning magnetic ring 144 is disposed outside the prestressed hydraulic clamp 146 and fixedly connected to the other side of the lower connecting base 142 for positioning during connection.

[0105] In this embodiment, the upper docking support 141 and the lower connecting base 142 are arranged opposite to each other; the upper docking support 141 is equipped with a fixed anchor claw 143, and the lower connecting base 142 consists of a prestressed hydraulic fixer 146 and a first positioning magnetic ring 144 disposed on the outer layer of the prestressed hydraulic fixer 146; here, the fixed anchor claw 143 can be a metal anchor claw.

[0106] When two adjacent box-shaped modules 131 are connected, the first positioning magnetic ring 144 provides magnetic attraction to attract the upper docking support 141 and the lower connecting base 142, so that the two adjacent box-shaped modules 131 are close to each other (until the fixed anchor claw 143 is embedded in the prestressed hydraulic fixer 146), to ensure that there is no relative displacement between the modules and that the connection can be accurately positioned; at the same time, the prestressed hydraulic fixer 146 applies prestress, which creates a continuous pre-tightening pressure at the connection interface between the two close box-shaped modules 131. This pre-tightening pressure enhances the overall rigidity and deformation resistance of the connection structure and prevents the connection from loosening, misalignment and cracking.

[0107] Preferably, the inner layer of the prestressed hydraulic fastener 146 can be provided with a sealing ring 145, which can be an elastic rubber sealing ring, to ensure the water tightness of the connection between the fixed anchor claw 143 and the prestressed hydraulic fastener 146; at the same time, the pre-tightening pressure formed at the connection interface of the two box-type modules 131 can press the sealing ring 145 to eliminate the splicing gap and further ensure the water tightness performance in the high-pressure seawater environment.

[0108] See Figure 4 In an optional embodiment of the present invention, the maintenance operation module 1 may specifically include a fixed support 104, a flexible steel arm 102, and a claw head 101.

[0109] The fixed support 104 is fixedly connected to the inner side of the dock wall, and a rotating support 103 is provided at the other end of the fixed support 104. The rotating support 103 allows the maintenance operation module 1 to be rotated and pitched on the inner plane of the dock wall. One end of the flexible steel arm 102 is fixedly connected to the other end of the rotating support 103; the claw head 101 is detachably connected to the other end of the flexible steel arm 102 and serves as the maintenance execution end of the maintenance operation module 1.

[0110] In this embodiment, multiple maintenance operation modules 1 are connected to the dock wall via fixed supports 104. A rotating support 103 is provided on the upper part of the fixed support 104, which can realize the 360-degree and ±45-degree pitch adjustment of the entire maintenance operation module 1 on the plane of the dock wall. This allows the maintenance operation module 1 to cover a large area of ​​the dock, and can be aligned with different maintenance points without moving the floating dock, thereby improving maintenance efficiency.

[0111] Here, the flexible steel arm 102 can be made of high-strength alloy material; preferably, the flexible steel arm 102 has a two-stage joint bending capability, which can flexibly bypass the equipment protrusion structure or narrow gap, and accurately reach the maintenance dead angle that is difficult to reach by traditional manual means, so as to reduce the difficulty of maintenance operation.

[0112] The head of the bendable steel arm 102 is detachably connected to the claw head 101, which serves as the core maintenance execution end of the maintenance operation module 1 and supports quick disassembly and replacement. Here, the claw head 101 can be replaced with a machine tool disassembly and assembly claw head or a hull welding claw head, etc., to meet the maintenance needs of different types of marine equipment in the floating dock.

[0113] See Figure 1 In an optional embodiment of the present invention, the cover plate shielding module 7 may include an inner cover plate and an outer cover plate. The inner cover plate is slidably connected to the inner side of the top of the dock wall; the outer cover plate is slidably connected to the outer side of the top of the dock wall; when the cover plate shielding module 7 is in a folded state (e.g., Figure 1 (As shown in the diagram), the outer cover plate is placed on the inner cover plate and located at one end of the top of the dock wall; during maintenance work in the floating dock, one of the inner and outer cover plates remains stationary at one end of the top of the dock wall, while the other slides along the top of the dock wall toward the other end until the ends of the two plates are joined together (as shown in the diagram). Figure 6 (as shown in the diagram), forming a shielded space. Here, both the outer and inner cover plates can be slidably connected to the top of the dock wall via a slide rail 71 located on the top of the dock wall. Here, the sliding drive method for the inner and outer cover plates is not limited; it can be a linear drive (such as an electric push rod, cylinder, or hydraulic cylinder), or a rotary drive method using a motor with a chain or a synchronous pulley with a synchronous belt.

[0114] In an optional embodiment of the present invention, both the outer cover plate and the inner cover plate may include multiple shielding units. The multiple shielding units are connected to form a semi-enclosed outer cover plate and an inner cover plate with the same shape but different sizes, so as to cover the floating dock body 13.

[0115] See Figure 5 Here, each shielding unit may include a composite reflective layer and an absorption layer 73. The composite reflective layer is a double-layered corrosion-resistant metal plate 72, used to reflect and block the penetration of high-frequency electromagnetic signals from the outside. The absorption layer 73 is disposed between the double-layered corrosion-resistant metal plates 72, and is a mesh-like conductive metal used to absorb and reduce low-frequency electromagnetic signal interference.

[0116] In this embodiment, each shielding unit is a composite shielding structure consisting of a double-layer corrosion-resistant metal plate 72 and an absorption layer 73. Through the synergistic effect of multiple materials, a highly efficient electromagnetic protection barrier is constructed to shield external signal interference and ensure data security and normal equipment operation during the maintenance of military equipment.

[0117] Preferably, both the outer and inner corrosion-resistant metal plates in the composite reflective layer can be made of high-purity low-carbon steel. More preferably, the steel plate is a galvanized steel plate that has undergone hot-dip galvanizing. After hot-dip galvanizing, it not only has excellent corrosion resistance and can resist the erosion of the structure by the humid environment inside the module library, but also blocks the penetration of medium- and high-frequency external electromagnetic signals through the electromagnetic reflection characteristics of the metal material.

[0118] Here, the absorption layer 73 of the double-layer corrosion-resistant metal plate 72 can be a high-density mesh conductive metal; preferably, the mesh conductive metal can be a high-density copper mesh, which, due to its excellent conductivity, can further absorb and reduce low-frequency electromagnetic interference. Simultaneously, the double-layer corrosion-resistant metal plate 72 and the absorption layer 73 form a dual shielding effect of "reflection + absorption," effectively blocking various external signal interferences such as radar signals, radio waves, and electromagnetic pulses.

[0119] See Figure 1 and Figure 7 In an optional embodiment of the present invention, the explosion-proof deck module includes multiple explosion-proof deck units 8, which are sequentially laid on the outside of the dock wall. Each explosion-proof deck unit 8 is detachably connected to the outside of the dock wall via a reserved interface 86 provided on the outside of the dock wall. Here, each explosion-proof deck unit 8 can be precisely docked to the reserved interface 86 on the outside of the dock wall using a robotic arm or large hoisting equipment to achieve a detachable connection with the outside of the dock wall.

[0120] Preferably, two adjacent explosion-proof deck units 8 can be connected by an electromagnetic adsorption unit 82. When the electromagnetic adsorption unit 82 is energized, it can generate a strong magnetic force, so that the two adjacent explosion-proof deck units 8 can fit tightly together to form a gapless integral explosion-proof deck module, thus preventing the explosion shock wave from seeping into the gap between the two adjacent explosion-proof deck units 8.

[0121] Continue reading Figure 1 and Figure 7 In an optional embodiment of the present invention, each explosion-proof deck unit 8 may include a basic structure layer 83 and a buffer structure layer 81, wherein the basic structure layer 83 is laid on the outside of the dock wall, and a second connection unit 85 matching the reserved interface 86 is provided on the inner side of the basic structure layer 83; the buffer structure layer 81 is laid on the outside of the basic structure layer 83.

[0122] In this embodiment, each explosion-proof deck unit 8 adopts a double-layer protective structure design of "basic structure layer 83 + buffer structure layer 81"; wherein, the basic structure layer 83, as a protective structure layer, is preferably made of Q690 high-strength steel, thereby enabling the basic structure layer 83 to have excellent impact resistance and deformation resistance at the protective structure level, and preventing the deck from structurally breaking due to external impact.

[0123] The buffer structure layer 81, as a composite armor layer, is laid on the outside of the base structure layer 83. Preferably, the buffer structure layer 81 can be a ceramic composite armor layer with a thickness of 50mm, which has both high hardness and anti-fracture properties. It can further attenuate the impact energy generated by the explosion through the "fracture energy absorption" method, effectively preventing high-speed flying objects such as shrapnel and gravel from penetrating the deck, and fundamentally protecting the safety of maintenance equipment and personnel inside the floating dock.

[0124] Preferably, a second positioning magnetic ring 84 and a second connecting unit 85 can be provided on the inner side of the basic structure layer 83; the second positioning magnetic ring 84 is disposed around the second connecting unit 85; when assembling the explosion-proof deck unit 8, the second positioning magnetic ring 84 provides magnetic attraction to attract the current explosion-proof deck unit 8 to the reserved interface 86 on the outside of the dock wall (the reserved interface 86 is surrounded by a corrosion-resistant magnetic metal that matches the size and shape of the second positioning magnetic ring 84) to achieve connection and positioning, at which time the second connecting unit 85 is embedded in the reserved interface 86. Here, the second connecting unit 85 can be a connecting column, the outer diameter of which matches the size of the reserved interface 86 to achieve snap-fit. In addition, the second connecting unit 85 can also fix the anchor claw, and a prestressed hydraulic fastener can also be provided at the reserved interface 86. When assembling the explosion-proof deck unit 8, the prestressed hydraulic fastener applies prestress, so that a continuous pre-tightening pressure is formed at the connection interface between the second connecting unit 85 and the reserved interface 86 to improve the connection stability between the two.

[0125] See Figure 1 and Figure 8 In an optional embodiment of the present invention, the anchor module 9 may specifically include an anchor chain 91, a suction pile system, and a high-holding-force anchor 97. The anchor chain 91 is disposed at the bottom of the floating dock body 13, with one end fixedly connected to the bottom of the floating dock body 13; one end of the suction pile system is detachably connected to the other end of the anchor chain 91; the high-holding-force anchor 97 is disposed at the other end of the suction pile system and located on both sides of that end; after the floating dock reaches the operating sea area, the anchor chain 91 can be driven and lowered to the target position via a hydraulic system, while the suction pile system and the high-holding-force anchor 97 embed themselves into the seabed rock strata for mooring.

[0126] In this embodiment, the anchor module 9 adopts a deep-sea anchor system, which can still provide reliable mooring force in water depths exceeding 100 meters, ensuring stable berthing of the floating dock and meeting the needs of deep-sea operations. The number of anchor modules is not specifically limited, but is determined by the length and width of the floating dock in actual application. They must also be evenly and symmetrically distributed on both sides of the bottom of the main body 13 of the floating dock to ensure stability during berthing.

[0127] Here, the anchor chain 91 is a high-strength anchor chain with excellent tensile strength, capable of withstanding the enormous tensile forces in the deep-sea environment. After the anchor chain 91 is lowered to the target depth in the target operating area, the suction pile system will generate negative pressure. Under this negative pressure, the suction pile system itself, along with the high-holding-force anchor 97, will automatically embed into the seabed rock layer to achieve stable berthing in 100-meter deep water. The high-holding-force anchor 97 is located at the bottom of the suction pile system. After embedding into the seabed rock layer, it can provide reliable gripping force under complex geological conditions in the deep sea, ensuring the fixing effect of the anchor module 9.

[0128] See Figure 8 In an optional embodiment of the present invention, the suction pile system may specifically include an anchor pile 95 and a suction valve 93. The anchor pile 95 has a cavity, and a connecting bracket 92 is provided at one end of the anchor pile 95, which is detachably connected to the other end of the anchor chain 91. The suction valve 93 is located at one end of the anchor pile 95 and communicates with the cavity within the anchor pile 95, used to evacuate the anchor pile 95 and generate negative pressure. During berthing, the suction valve 93 is opened, evacuating the anchor pile 95 and generating negative pressure. Under this negative pressure, the anchor pile 95 and the high-holding-power anchor 97 are embedded into the seabed rock strata, achieving stable berthing in deep water up to 100 meters deep.

[0129] Preferably, the top outer edge of the anchor pile 95 is also provided with a lifting lug 94. When the floating dock arrives at the operating sea area, the hydraulic system drives the anchor chain 91 to be lowered. At this time, a large floating crane can connect the lifting lugs 94 on both sides of the anchor pile 95 to lower the anchor pile 95 to the corresponding target position. An underwater robot connects the lower end of the anchor chain 91 to the connecting bracket 92 at the upper end of the anchor pile 95. The anchor pile 95 is evacuated by the suction valve 93 and negative pressure is generated. The negative pressure causes the anchor pile 95 to embed into the seabed rock layer along with the high holding force anchor 97. In this embodiment, a single anchor pile 95 can provide a mooring force greater than or equal to 1500kN, which can meet the mooring requirements of water depths of 100-200 meters.

[0130] Preferably, a serrated structure 96 can be provided on the bottom end face of the anchor pile 95 to further enhance the embedment stability of the suction pile system on the rocky seabed.

[0131] See Figure 9In an optional embodiment of the present invention, the aforementioned modular deep-sea floating dock may further include a power module located at the bottom of the floating dock body 13. Specifically, the power module may include an azimuth thruster 2 installed at the bottom of the stern of the floating dock body 13 and lateral thrusters 3 distributed on both sides of the bottom of the floating dock body 13. The azimuth thruster 2, in conjunction with the lateral thrusters 3, provides the driving force required for the operation of the floating dock. Here, both the azimuth thruster 2 and the lateral thrusters 3 are existing thrusters, such as propeller thrusters, and their specific structures will not be described in detail.

[0132] The azimuth thruster 2 can be installed at the bottom of the stern. The azimuth thruster 2 can rotate 360 ​​degrees in all directions and can quickly switch the thrust direction according to the operation requirements, providing a stable and efficient main driving force for the floating dock, supporting it to complete core actions such as long-distance displacement and precise positioning.

[0133] Lateral thrusters 3 are distributed on both sides of the bottom of the floating dock body 13, preferably with six units arranged symmetrically. These lateral thrusters 3 are retractable lateral thrusters with "on-demand lifting" characteristics; they can be lowered into the water during operation and retracted into the floating dock when not in operation, effectively avoiding collisions with marine debris or seawater corrosion, and extending the equipment's service life. When the floating dock is floating and underway, the lateral thrust provided by the lateral thrusters 3 and the main driving force provided by the azimuth thrusters 2 work together to maintain the balance of the floating dock. Simultaneously, the arrangement of the azimuth thrusters 2 and lateral thrusters 3 also enhances the maneuverability and flexibility of the floating dock during operation.

[0134] See Figure 1 In an optional embodiment of the present invention, the aforementioned modular deep-sea floating dock may further include a floating dock control module 5, which is located at the bow of the floating dock body 13 and is used to control the operation of the floating dock. Here, the floating dock control module 5 may be a floating dock control cab, which is equipped with driving control equipment. This driving control equipment can communicate with the corresponding module to control the operation of the corresponding module, thereby controlling the operation of the floating dock.

[0135] Preferably, the aforementioned modular deep-sea floating dock may also include a dual-use intelligent operation and maintenance system, which is integrated into the driving control equipment. This system supports dual-channel communication encryption with both military and civilian codes. This encryption method can ensure the security of civilian ship maintenance management information and military equipment support information during transmission and prevent information leakage.

[0136] Preferably, the dual-use intelligent operation and maintenance system integrates civilian ship maintenance management information with military equipment support information to distinguish between civilian and military modes, enabling it to provide efficient maintenance services for civilian ships in peacetime and serve as a command center for military equipment support in wartime, thereby improving the operation and maintenance efficiency and support capabilities of the floating dock.

[0137] When the floating dock is in civilian mode: the dual-use intelligent operation and maintenance system focuses on the "efficiency and precision" of civilian ship maintenance, aiming to provide efficient maintenance services for civilian ships; by integrating resources such as ship maintenance records, fault databases, and parts supplier information, it automatically identifies high-frequency maintenance problems, optimizes parts procurement cycles and maintenance processes through big data analysis, thereby improving maintenance efficiency;

[0138] When the floating dock is in military mode: the dual-use intelligent operation and maintenance system can quickly switch to the "military equipment support command center" to achieve unified scheduling and management of ship maintenance tasks; at the same time, by integrating military equipment support information, maintenance needs of various ships, support base resources (such as maintenance personnel, spare parts inventory, and emergency repair equipment), battlefield environment information, etc., the system can achieve optimal resource allocation through intelligent scheduling algorithms, thereby improving the response speed and support capability of ship maintenance.

[0139] See Figure 1 In an optional embodiment of the present invention, the above-mentioned modular deep-sea floating dock may further include a life support module 6, which is disposed at the bow of the main body of the floating dock 13 and located below the floating dock control module 5.

[0140] Here, the living support module 6 is divided into functional areas such as accommodation, catering, and medical care according to the living needs of maintenance personnel, and corresponding facilities are configured. For example, the accommodation area is equipped with comfortable beds, storage cabinets, and other furniture; the catering area is equipped with kitchen equipment and tables and chairs; and the medical area is equipped with basic medical equipment and medicines. At the same time, it is necessary to ensure that the ventilation, lighting, water supply, and power supply systems inside the module are operating normally.

[0141] See Figure 1 In an optional embodiment of the present invention, the above-mentioned modular deep-sea floating dock may further include an energy module 4, which is disposed at the bow of the main body 13 of the floating dock and above the life support module 6 and located in the floating dock control module 5; here, the energy module 4 integrates power generation and energy storage and is used to provide the energy required for the operation of the floating dock.

[0142] See Figure 10 and Figure 11 Specifically, energy module 4 may include a power generation unit and an energy storage unit 43. The power generation unit is a photovoltaic-wind turbine integrated power generation unit, used to convert solar and wind energy into electrical energy to achieve the coordinated collection of solar and wind energy.

[0143] The energy storage unit 43 is located below the power generation unit and is used to store and release the electrical energy generated by the power generation unit. Preferably, the energy storage unit 43 can be a lithium iron phosphate battery pack, which has high safety and long cycle life, can generate electrical energy in real time, and can realize charge and discharge management through an intelligent control system to ensure the stability of energy supply.

[0144] Continue reading Figure 10 and Figure 11 In an optional embodiment of the present invention, the power generation unit may specifically include a wind turbine main shaft 44 and a plurality of blades 41. A magnetic levitation drive unit 42 is disposed at one end of the wind turbine main shaft 44, and an energy storage unit 43 is disposed below the magnetic levitation drive unit 42. The plurality of blades 41 are arranged around the outer side of one end of the wind turbine main shaft 44 and connected to the magnetic levitation drive unit 42. Each blade 41 has a photovoltaic film coated on its surface. When the power generation unit generates electricity, photovoltaic power generation is achieved through the photovoltaic film, and the magnetic levitation drive unit 42 drives the plurality of blades 41 to rotate around the wind turbine main shaft 44 to generate wind power.

[0145] In this embodiment, the main shaft 44 of the wind turbine can be made of high-strength hollow steel pipe, which can serve as an internal channel for cables and shaft drive equipment. Multiple blades are arranged around the outer side of the main shaft 44. In one feasible example, four airfoil blades 41 can be symmetrically arranged on the outer side of the main shaft 44. The blades 41 are preferably made of glass fiber reinforced plastic (FRP) material, which has both lightweight and marine corrosion resistance characteristics. At the same time, the outer surface of each blade 41 is fully covered with a flexible photovoltaic film. This photovoltaic film can efficiently absorb solar energy and convert it into electrical energy during the day, thereby realizing the functional integration of "blade as photovoltaic panel".

[0146] Here, the magnetic levitation drive unit 42 is integrated into one end of the wind turbine main shaft 44. The magnetic levitation drive unit 42 can be a magnetic levitation shaft, which is rotatably connected to a shaft drive device (such as a servo motor) set in the hollow wind turbine main shaft 44. Compared with traditional mechanical bearings, the magnetic levitation shaft can significantly reduce the operating friction resistance, allowing the blades 41 to start rotating in low wind speed environments and convert wind energy into electrical energy. At the same time, the low wear characteristics of the magnetic levitation shaft can also reduce the wear and tear on the equipment caused by the high humidity and high salinity environment of the ocean and extend the service life of the power generation unit.

[0147] See Figure 10 and Figure 11In an optional embodiment of the present invention, the power generation unit may further include a root shaft 45, which is symmetrically arranged outside the magnetic levitation drive 42 unit. The root shaft 45 is connected to the magnetic levitation drive unit 42 and rotates around the main shaft 44 of the wind turbine under the drive of the magnetic levitation drive unit 42. The root shaft 45 corresponds one-to-one with the blades 42, and one end of the blade 41 is sleeved on the corresponding root shaft 45. When the magnetic levitation drive unit 42 drives the root shaft 45 to rotate axially around the main shaft 44 of the wind turbine, the root shaft 45 will drive the blades 41 sleeved on it to rotate, thereby converting wind energy into electrical energy. At the same time, by driving the root shaft 45 to rotate radially along the main shaft 44 of the wind turbine, the blades 41 are driven to unfold or fold radially along the main shaft 44 of the wind turbine.

[0148] In this embodiment, the blade 41 can switch between "unfolding" and "folding" via the root shaft 45: when encountering extreme sea conditions such as typhoons or severe storms, by driving the root shaft 45 to rotate radially along the main shaft 44 of the wind turbine, the blade 41 can be rotated and gradually moved closer to the main shaft 44 of the wind turbine until it is in a folded state completely close to the main shaft 44 of the wind turbine (e.g., Figure 11 As shown in the diagram), the blades 41 are in a retracted state with a certain distance between them and the main shaft 44 of the wind turbine, thus achieving the folding motion of the blades 41. When the blades 41 are in a folded or retracted state, the windward area of ​​the power generation unit can be reduced, lowering the risk of equipment damage. When the sea state is calm, by driving the root shaft 45 to rotate radially along the main shaft 44 of the wind turbine, the blades 41 can be rotated and moved away from the main shaft 44 of the wind turbine, until they are in an open state perpendicular to the main shaft 44 of the wind turbine (as shown in the diagram). Figure 10 (as shown in the image) to maximize the capture of solar and wind energy;

[0149] In addition, the blade 41 supports precise angle fine-tuning according to the sea wind direction. It can collect real-time wind direction data through the wind direction sensor built into the module and control the number of rotations of the root shaft 45, thereby controlling the angle of attack of the blade 41 within a certain range, such as ±15°, to ensure that the blade 41 always faces the airflow at the optimal angle, avoiding wind energy waste caused by airflow separation. This allows the power generation unit to improve the wind energy conversion efficiency by more than 20% under different wind direction and wind speed conditions.

[0150] See Figure 1 and Figure 12In an optional embodiment of the present invention, the aforementioned modular deep-sea floating dock may further include a wave prediction sensor 10, a first attitude correction thruster 11, and a second attitude correction thruster 12. The wave prediction sensor 10 is disposed on the top of the dock wall and is used to monitor wave disturbance data in real time. The first attitude correction thruster 11 is symmetrically disposed on the outer side of the dock wall and is used to adjust the direction of its inner propeller 111 to correct the floating dock's directional deviation caused by wave disturbance. The second attitude correction thruster 12 is symmetrically disposed on the outer side of the dock wall and spaced apart from the first attitude correction thruster 11, and is used to provide longitudinal thrust to adjust the floating dock's displacement changes caused by wave disturbance.

[0151] In this embodiment, multiple sets of high-precision wave prediction sensors 10 can be deployed at key locations on the top of the dock wall (such as the top decks on both sides of the floating dock). These sensors integrate wave height meters, current meters, and attitude sensors, and can simultaneously monitor wave disturbance data, such as the wave height, period, and propagation direction of swells, as well as the real-time sway angle (roll, pitch, heave) of the floating dock. Based on the monitored wave disturbance data, the floating dock control module 5 can control the system operation of the first attitude correction thruster 11 and the second attitude correction thruster 12 to achieve all-round attitude correction of the floating dock.

[0152] Here, the second attitude correction thruster 12 can be an existing thruster, such as a propeller thruster, and the specific structure will not be described in detail. As a supplementary source of stable driving force, the second attitude correction thruster 12 continuously outputs longitudinal thrust to counteract the heave and displacement of the floating dock body 13 caused by swells, ensuring that the floating dock maintains a stable working attitude in wave environment and providing a good working environment for maintenance operations.

[0153] See Figure 12 The first attitude correction thruster 11 can be a six-degree-of-freedom omnidirectional thruster, which specifically includes a propeller 111, a six-degree-of-freedom hydraulic telescopic rod 112, and a connecting base 113. One side of the connecting base 113 is fixedly connected to the outer side of the dock wall, and the six-degree-of-freedom hydraulic telescopic rod 112 is disposed between the connecting base 113 and the propeller 111, with its two ends rotatably connected to the other side of the connecting base 113 and the inner side of the propeller 111, respectively. The first attitude correction thruster 11 can flexibly adjust the direction of the propeller 111 (e.g., covering horizontal, vertical, and rotational directions) via the six-degree-of-freedom hydraulic telescopic rod 112. After adjusting the direction of the propeller 111, the propeller 111 can provide driving force in the corresponding adjusted direction to counteract the rolling, pitching, and horizontal deviation of the floating dock caused by swells.

[0154] The modular deep-sea floating dock provided by the above embodiments of the present invention solves the problems of instability in deep-sea operations, slow conversion between military and civilian functions, and long construction cycle of traditional floating docks; it realizes the needs of emergency repair and routine maintenance of marine equipment such as military ships and civilian vessels in the ocean, realizes the dual use of floating docks for military and civilian purposes, reliable operation and rapid deployment in the deep sea, improves maintenance efficiency, and provides core technical support for the national deep-sea equipment support system. Specifically, this floating dock integrates military and civilian functions. By constructing an interchangeable military-civilian general-purpose functional module library (including box-type modules, maintenance operation modules, energy modules, power modules, and life support modules) and a military-enhanced module library (cover shielding modules, explosion-proof deck modules), it can quickly switch between military and civilian functions, improve the operational flexibility of the floating dock, and meet the flexible needs of marine equipment maintenance systems under the military-civilian integration development strategy. At the same time, the floating dock adopts deep-sea pile anchor modules, wave prediction sensors, and attitude correction thrusters to ensure the stability of the floating dock under complex deep-sea conditions. In addition, the modular box-type modules of the main body of the floating dock can be quickly assembled by unmanned assembly equipment, shortening the on-site assembly time, solving the problem of long construction cycles of traditional floating docks, improving the rapid deployment capability of the floating dock, and enabling timely response to emergency maintenance needs of marine equipment.

[0155] The above description represents the preferred embodiments of the present invention.
