Description

Technical Field

[0001] This invention relates to the field of temporary berthing equipment for ships, and in particular to a flexible temporary berthing device based on air cushion-water plug coupling. Background Technology

[0002] Inland waterway shipping is an important component of the comprehensive transportation system and the comprehensive utilization of water resources. my country ranks first in the world in both inland waterway shipping volume and navigable waterway mileage. With the increasing trend of larger, more standardized, and more specialized ships, improving the utilization rate of waterway and terminal resources, optimizing ship navigation efficiency, and resolving the contradiction between supply and demand of transport capacity have become key issues in promoting high-quality development of inland waterways.

[0003] In the existing technology, the temporary mooring of ships is usually set up in the following four forms: gravity structure, positioning pier structure, berthing pier structure, and floating structure. (1) Gravity structure relies on its own weight to stabilize in the anchorage, has a long construction period, and is suitable for anchorage areas in plain waterways with slow water flow; (2) Positioning pier structure fixes the position of floating facilities and adapts to large water level fluctuations, but is prone to siltation; (3) Berthing pier structure adapts to large span layout, improves the "small load and dense berth" layout and alleviates anchorage siltation; (4) Floating structure, such as floating piers, reduces the collision energy of large ships. Floating facilities can adapt to water level changes, are easy to construct, and have little interference with the riverbed.

[0004] For the first type of gravity structure, which relies on its own weight to stabilize at the anchorage, it has high overall rigidity and strong impact resistance. However, the construction period for temporary cofferdams in the anchorage is long, which affects flood control during the flood season and is not suitable for large water level fluctuations and flood discharge requirements. For the second type of positioning pier structure, which can cope with large ships and large-sized pontoons, the siltation phenomenon that is common in fixed positioning and berthing structures has a great impact on the efficiency of shipping vessels due to the time, accuracy and mud dumping operations of dredging construction. For the third type of berthing pier structure, which improves the defects of the traditional "small loading and dense pier" layout of the elevated vertical wharf and alleviates the problem of anchorage siltation, however, in actual operation, the high flow velocity, high sand content and non-standard berthing cause erosion and impact damage to the wharf components, which pose a serious challenge to the safe operation of the structure. For the fourth type of floating structure, which relies on buoyancy and anchoring through single-point mooring or multi-point mooring, it can adapt to water level changes and meet flood discharge requirements. Single-point mooring is limited by the minimum water depth, current velocity, and floating debris, and has weak constraints on floating structures, resulting in a large turning radius. Multi-point mooring, using tensioned mooring, catenary mooring, and hybrid mooring methods, relies solely on the tension of anchor chains or cables to adapt to water level variations. Research on the coupled response and attitude control of loads such as high current speeds and large ship berthing remains limited.

[0005] Existing research has shown that air-floating structures, under floating stress, exhibit superior stability in catenary mooring compared to traditional bottom-sealed platforms. For small length-to-wavelength ratios, the uniform pressure distribution within the air cushion of the air-floating structure allows it to evenly absorb bottom pressure variations caused by environmental and external loads, effectively reducing mooring loads. Therefore, a flexible temporary mooring device based on the air cushion-water plug coupling effect of an air-floating structure is designed to provide a technical solution to the aforementioned problems. Summary of the Invention

[0006] Therefore, it is necessary to provide a flexible temporary mooring device based on air cushion-water plug coupling to address the aforementioned technical problems.

[0014] As a preferred embodiment of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention, the stern of the air-floating box structure is fixed with an outboard motor rack to reserve an installation position for the propeller.

[0015] As a preferred embodiment of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention, the anchoring structure includes a tensioned cross anchor cable positioning and an automatic cable retraction device. Tensioned cross anchor cable positioning is provided at the bottom of both ends of the air-floating box structure. Each tensioned cross anchor cable positioning includes two anchor cables. The bottoms of the two anchor cables at the same end of the air-floating box structure are cross-arranged. An automatic cable retraction device for retracting and deploying anchor cables is installed inside the air-floating box structure.

[0016] As a preferred embodiment of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention, the automatic cable deployment and retraction device includes a lasso roller, a relay gearbox, a cable winch, and a bubble level gauge. The cable winch is fixed inside the air-floating box structure. The output end of the cable winch is connected to the relay gearbox. The output end of the relay gearbox is connected to the lasso roller. The outer side of the lasso roller is fixed to the anchor cable. Bubble level gauges are provided at both ends of the air-floating box structure.

[0017] As a preferred embodiment of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention, the plurality of mooring bollards are divided into two rows, and the two rows of mooring bollards are symmetrically arranged on both sides near the edge of the air-floating box-type structure.

[0018] As a preferred embodiment of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention, it further includes a socket joint for connecting two adjacent air-float box-type structures. The socket joint includes a first connecting plate, a positioning plate, a second connecting plate, a first pin, and a second pin. The first connecting plate is fixed to one of the air-float box-type structures, and the second connecting plate is fixed to the other air-float box-type structure. The first connecting plate and the second connecting plate are interleaved and inserted into one end of the first connecting plate, which is fixed with a positioning plate. The first connecting plate and the second connecting plate are connected by a first pin, and the top of the positioning plate is inserted with a second pin.

[0019] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0020] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:

[0021] 1. This invention provides a flexible temporary mooring device based on air cushion-water plug coupling. It uses a bottomless structure to form an open water cavity. The air and water within the open water cavity create an "air cushion-water plug coupling" buffering effect. During the berthing impact, the water in the cavity is compressed to form a water plug, and the air above the water plug is compressed to form an air cushion. Both absorb and buffer the impact energy, reducing the impact load. The device features a six- or multi-compartment design, with each compartment independently enclosed to form a buoyancy control unit. By adjusting the air volume of each compartment, the buoyancy distribution is changed, and the attitude and height of the air-floating box structure are adjusted to adapt to different working conditions and ship mooring requirements. The streamlined arc-shaped box head design reduces upstream water flow disturbance, improves ship guidance and berthing stability, achieves flexible buffering, and avoids rigid collisions. It enhances the overall stability of the device, making it suitable for complex hydrological environments. It also reduces damage to the hull and device structure, extending the device's lifespan.

[0022] 2. This invention does not rely on shore-based conditions and has a certain deployment capability in soft foundations or ecologically sensitive areas. Furthermore, due to the combination of the air-floating box structure and the anchoring structure in the device, the impact force of ships mooring is reduced while maintaining the stability of the device.

[0023] 3. This invention employs a large air-floating box structure, with the device's streamlined arc-shaped box head designed to be streamlined, which can meet the temporary mooring needs of multiple ships while reducing the impact of upstream water flow. The combination of multiple air-floating box structures can form a floating bridge, enabling emergency response.

[0024] 4. The anchor cables of this invention are arranged in a crisscross pattern at the lower part of both ends of the air-floating box structure to form a spatial force-bearing system; equipped with an automatic cable winding and unwinding device, which is coordinated and controlled by a relay gearbox, a cable winch and a bubble level gauge, can dynamically adjust the length of the anchor cables to respond to water level changes, waves and other disturbances, and achieve anchor cable tension balance, thereby improving the device's steady-state maintenance capability under wave disturbances; providing automated hydrological adaptability and reducing manual intervention; ensuring that the device maintains a reasonable positional relationship with the hull and preventing the device from drifting or being pulled off course.

[0025] 5. The bollards of this invention are installed on the upper part of the air-floating box-type structure and are driven to rise and fall by electric push rods; the position of the bollards is dynamically adjusted according to the draft of the hull to ensure the optimal force direction of the anchor cable; they are arranged in groups on both sides of the device to support multiple ships to moor at the same time; thus enabling different types of ships to safely berth on the same device; avoiding problems such as cable tangling and eccentric pulling caused by excessive cable angle; and improving the safety and adaptability of mooring and berthing.

[0026] 6. The present invention is equipped with a standardized mounting bracket interface at the tail, which supports the rapid installation of the propulsion unit; it can be transferred and integrated into the water by its own power or external force; thereby improving the emergency response mobility of the device; reducing deployment and withdrawal time; and supporting the rapid construction of temporary floating bridges or transition platforms.

[0027] 7. This invention connects multiple air-floating box-type structures through connectors such as pins, hinges, and limit lock pins; it achieves standardization of structural modules and supports large-scale coordinated deployment; thereby constructing a multi-functional floating bridge suitable for temporary evacuation, material transfer, etc.; it meets the needs of large-scale deployment and emergency response scenarios; and it enhances the breadth and flexibility of the device's application scenarios.

[0028] 8. The present invention, through the cooperation of the first connecting plate, the positioning plate, the second connecting plate, the first pin, and the second pin, enables two adjacent air-floating box structures to approach each other to form a floating bridge. At this time, the first connecting plate and the second connecting plate are connected in an interlaced manner, and the first connecting plate and the second connecting plate are positioned by the first pin. At this time, the first connecting plate and the second connecting plate form a hinged connection. The connection can also be increased by the second pin mounted on the positioning plate. The installation of the first pin and the second pin forms a semi-rigid or rigid connection between the first connecting plate and the second connecting plate. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] Example 1

[0043] Reference Figures 1-4 A flexible temporary mooring device based on air cushion-water plug coupling includes an air-floating box structure 1, an anchoring structure 2, and a mooring device 3. The anchoring structure 2 is located at the bottom of the air-floating box structure 1, thereby placing the air-floating box structure 1 in the middle of the device, which serves as the main floating platform of the device. The anchoring structure 2 is located at the bottom of the device to achieve stable positioning of the entire device in the water. The mooring device 3 is located at the top of the air-floating box structure 1, thereby fixing the position of the device through the mooring device 3.

[0044] The bottom of the air-floating box structure 1 is a bottomless structure 4, specifically, the bottom of the box is open and not sealed. Specifically, it is a bottomless structure 4 with an open bottom and a closed top. The inner side of the bottom of the air-floating box structure 1 has a cavity. The air-floating box structure 1 is made of steel plates. The cavity is divided into six compartments 5 by steel plates, or multiple compartments. The six compartments 5 are not sealed and each compartment of the six compartments 5 can be sealed independently.

[0045] The head of the air-floating box structure 1 is a rounded streamlined box head 6, which is used to weaken the impact of the incoming flow; the tail of the air-floating box structure 1 is fixed with an outboard motor rack 15, which is used to reserve an installation position for the propeller, and can be equipped with a propulsion module as needed to achieve self-propulsion and transfer.

[0046] Anchor structure 2 is used to connect air-floating box structure 1 and anchorage to achieve a fixing effect. Anchor structure 2 includes tensioned cross anchor cable positioning 7 and automatic cable winding and unwinding device 8. Tensioned cross anchor cable positioning 7 is provided at the bottom of both ends of air-floating box structure 1, so that the tensioned cross anchor cable positioning 7 at the head and tail of air-floating box structure 1 can achieve three-dimensional tension control by cross anchoring at both ends. Each tensioned cross anchor cable positioning 7 includes two anchor cables 9, and the two anchor cables 9 at the same end are cross-set at the bottom of air-floating box structure 1.

[0047] Preferably, the two anchor cables 9 at the same end are assembled in the form of cross mooring, which has a flexible connection in specific applications, so that the air-floating box structure 1 on the water surface can float and buffer with the water surface while the connection is stable.

[0048] Meanwhile, the water in the six compartments 5 at the bottom of the floating box structure 1 is compressed to form a water plug, and the air above the water plug is compressed to form an air cushion. The two work together to absorb and buffer the impact energy, achieving a flexible way to reduce the impact load, thus avoiding damage caused by the impact force due to the rigid connection method.

[0049] The air-floating box structure 1 is equipped with an automatic cable-laying device 8 for laying and reeling in the anchor cable 9. Through the power drive of the automatic cable-laying device 8 and the linkage with the sensor feedback system, the length of the anchor cable 9 can be automatically adjusted according to the water level change to maintain stable mooring tension. The automatic cable-laying device 8 includes a cable winch 10, a relay gearbox 11, a winch 12, and a bubble level gauge 13. The winch 12 is fixed inside the air-floating box structure 1. The output end of the winch 12 is connected to the relay gearbox 11, and the output end of the relay gearbox 11 is connected to the cable winch 10. The operation of the winch 12 drives the cable winch 10 to rotate through the relay gearbox 11. The outer side of the cable winch 10 is fixed to the anchor cable 9, so that the rotation of the cable winch 10 drives the laying and reeling in the anchor cable 9. Bubble level gauges 13 are set at both ends of the air-floating box structure 1, so that the two bubble level gauges 13 are located at the head and tail ends of the air-floating box structure 1, respectively.

[0050] Preferably, the two bubble level gauges 13 are composed of a main unit and a probe unit respectively. The two main units are installed in the inner cavity of the air flotation box structure 1 near the front and rear ends, and the two probe units are installed on the outer side of the front and rear ends of the air flotation box structure 1 near the bottom. The main unit and the probe unit are connected by an air pipe.

[0051] In this embodiment, the relay gearbox 11 and the cable winch 12 are both located at the center of the beginning and end sides of the cavity.

[0052] The mooring device 3 includes multiple bollards 14, which are telescopic bollards, enabling docking of vessels with different drafts at the same mooring height. The length of the bollards can be dynamically adjusted based on the monitored hull height. The multiple bollards 14 are arranged in two rows, symmetrically on both sides of the air-floating box structure 1 near the edge, allowing the device to be fixed in different positions by connecting the bollards 14.

[0053] In this embodiment, the structure of the mooring bollard 14 with telescopic structure is specifically adjusted by an electric push rod to make its mooring point flush with the ship's deck, thereby ensuring that the anchor cable is subjected to reasonable force direction and preventing cable tangling or eccentric pulling due to excessive cable angle.

[0054] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0055] The usage process of the flexible temporary mooring device based on air cushion-water plug coupling provided by this invention is as follows:

[0056] In actual use, ships can approach the device by towing or self-propelled means. Before docking, the device monitors the current water depth and current velocity data in advance through the bubble level gauge 13, and activates the automatic mooring device 8 to adjust the length of the anchor cable 9, so that the device maintains a horizontal attitude and completes dynamic pre-positioning under the current hydrological conditions. When the ship approaches the device, the arc-shaped streamlined box head 6 at the front of the device can effectively reduce the disturbance of the incoming water flow field on the device's wake vortex, thereby guiding the ship to approach steadily and avoiding yaw caused by sideslip or vortex. At the moment of contact between the hull and the device, the air-floating box structure 1 in the device produces a significant vertical buffering effect. The gas is rapidly compressed under pressure to form a flexible damping band, which significantly reduces the impact force of the hull on the device and ensures structural safety. Subsequently, the crew uses the retractable mooring bollard 14 on the device to complete the mooring.

[0057] After mooring is completed, the automatic cable reeling and deployment device 8 enters continuous operation mode. The cable reeling drum 10 is driven by the linkage of water level monitoring signal and tension feedback data to reel in and deploy the anchor cable according to the tension of each anchor cable, so as to achieve anchor cable tension balance control. The device can automatically maintain a relatively stable position under disturbances such as waves and sudden changes in water level, preventing the overall structure from drifting or the hull from swaying due to cable force fluctuations.

[0058] If multiple units of this device are deployed, their air-floating box structure 1 can be connected laterally through standardized connecting components (pins, hinges and limit locks) to form a floating bridge-type modular structure, which is suitable for long-distance berths, emergency evacuation or temporary transfer platforms.

[0059] Example 2

[0060] An embodiment is provided based on the above embodiment one.

[0061] An emergency berthing test for hazardous chemical transport was conducted at an anchorage in the Three Gorges Reservoir area. Three sets of this device were deployed side-by-side to construct a temporary berthing system. Each set of devices measures 120m × 20m × 6m and adopts a six-compartment (5 compartments) design. Each compartment is independently equipped with an air compression / discharge device, which is centrally controlled. The three sets of air-floating box-type structures 1, combined with the mooring structure 2, have an adjustable draft range of 3.0m to 4.5m, capable of berthing vessels from 0 to 10,000 tons.

[0062] Each device has two 100mm diameter high-strength anchor cables 9 laid crosswise at both ends, for a total of 12 cables. During the initial deployment, the device is towed to the target anchorage by a construction vessel using a towline. The automatic cable reeling and unloading device 8, in conjunction with remote control commands, completes the initial positioning. After positioning, the device enters a hydrological monitoring self-stabilization mode. The system automatically samples the water level periodically and triggers the automatic anchor cable adjustment function when the water level change exceeds ±10cm, which can cope with sudden rises in water level caused by short-term heavy rainfall.

[0063] During operation, vessels temporarily moored use retractable bollards 14 on both sides for balanced berthing. During berthing, the air-floating box structure 1 combined with the anchoring structure 2 has both rigid and flexible characteristics, which can significantly reduce rigid collision damage to the vessel during berthing compared to fixed berthing piers.

[0064] After completing the emergency mission, each device can be autonomously transferred to the shore storage area via a certain power propeller installed on the outboard motor rack 15. Alternatively, the devices can be connected laterally to be converted into a floating bridge, making them suitable for a wider range of complex water applications.

[0065] Example 3

[0066] Reference Figures 5-7A flexible temporary mooring device based on air cushion-water plug coupling further includes a socket joint for connecting two adjacent air-float box-type structures 1. The socket joint includes a first connecting plate 16, a positioning plate 17, a second connecting plate 18, a first pin 19, and a second pin 20. The first connecting plate 16 is fixed to one of the air-float box-type structures 1, and the second connecting plate 18 is fixed to the other air-float box-type structure 1. The first connecting plate 16 and the second connecting plate 18 are interlocked, thereby enabling the connection between the two adjacent air-float box-type structures 1 through the interlocking of the first connecting plate 16 and the second connecting plate 18. The first connecting plate 16 is fixed with a positioning plate 17 at one end. The first connecting plate 16 and the second connecting plate 18 are connected by a first pin 19, so that the first pin 19 is inserted from one end of the first connecting plate 16 and the tail end of the first pin 19 passes through the first connecting plate 16 and enters the interior of the second connecting plate 18 and then enters the interior of the positioning plate 17. The top of the positioning plate 17 is connected with a second pin 20, so that the position of the second pin 20 can be positioned after entering the interior of the positioning plate 17, and the tail end of the second pin 20 enters the sliding first pin 19.

[0067] The following is the usage process of the flexible temporary mooring device based on air cushion-water plug coupling provided by the present invention: In actual use, when two adjacent air-floating box structures 1 of multiple devices need to be connected, the first connecting plate 16 is fixed to one of the air-floating box structures 1, and the second connecting plate 18 is fixed to the other air-floating box structure 1. Then, during connection, the second connecting plate 18 is inserted into the sliding inner side of the first connecting plate 16, and a first pin 19 is assembled at one end of the first connecting plate 16. The tail end of the first pin 19 passes through the first connecting plate 16 and enters the interior of the second connecting plate 18 and then enters the interior of the positioning plate 17. At this time, the first connecting plate 16 and the second connecting plate 18 are hinged, which allows a certain angle to be formed between the two adjacent air-floating box structures 1. Then, the second pin 20 is slidably installed inside the positioning plate 17, and the position of the first pin 19 is fixed by the second pin 20. By installing the first pin 19 and the second pin 20 simultaneously, a semi-rigid or rigid connection is formed between the first connecting plate 16 and the second connecting plate 18.
