Description

Technical Field

[0001] This invention relates to the field of shipbuilding and marine engineering technology, and in particular to a highly seaworthy detachable pentamaran and its operating method. Background Technology

[0002] my country possesses abundant islands and vast marine resources. However, some areas have long distances between island groups and consistently high waves, resulting in low voyage rates for ships operating between these island groups.

[0003] In existing technologies, inter-island transportation mainly relies on trimaran vessels and landing craft. These vessels meet inter-island transportation needs to a certain extent, especially in relatively calm sea environments. However, traditional vessels used for inter-island transportation are inadequate when dealing with complex sea conditions. Trimaran vessels with side hulls only have the function of adjusting their sailing state and improving their seakeeping after ballast loading, but they lack loading capacity. While landing craft can cope with certain tidal flat environments, their sailing efficiency and stability are poor over long distances and in high sea states. In addition, the construction of wharves on small islands within the archipelago varies, making it difficult for traditional vessels to adapt to diverse island landing conditions. They often face problems such as difficulty in berthing and cumbersome transshipment, failing to efficiently solve the "last mile" bottleneck in island transportation. This limits the efficiency of inter-island transportation. There is an urgent need for a new type of highly adaptable vessel that can adapt to various island landing conditions and has excellent seakeeping performance, so that it can sail in high sea states and meet the needs of inter-island transportation. Summary of the Invention

[0004] To address the shortcomings of existing production technologies, the applicant provides a highly seaworthy detachable pentamaran and its operating method. By setting up a detachable mother ship and multiple pairs of sub-ships, it can meet inter-island transportation needs based on multiple modes, has strong adaptability and good seakeeping, and can sail in high sea states, thereby effectively improving the efficiency of inter-island transportation.

[0005] The technical solution adopted in this invention is as follows: A highly seaworthy separable pentamaran includes a mother ship, on which two pairs of sub-ships are configured, each pair of sub-ships including two sub-ships arranged symmetrically relative to the mother ship. The deck of the mother ship extends to both sides to form symmetrical connecting bridges. At least one receiving slot is opened at the bottom of each connecting bridge. The receiving slots are arranged one-to-one with the daughter ships. A connecting module is installed in each receiving slot. Individual sub-boats can be connected to the corresponding receiving slot via a connecting module, or individual sub-boats can be separated from the corresponding receiving slot via a connecting module.

[0006] As a further improvement to the above technical solution: The mother ship has a slender hull.

[0007] The pairs of child ships are arranged at intervals along the length of the mother ship, with one pair of child ships located at the stern of the mother ship.

[0008] Each sub-ship adopts a single-angle hull design.

[0009] The bottom of each individual boat is covered with abrasion-resistant material.

[0010] Each sub-boat has a hatch cover installed on its top, and a telescopic ladder leading to the hatch cover is installed inside the sub-boat.

[0011] Both child ships in a single pair are simultaneously connected to the mother ship, or both child ships in a single pair are simultaneously separated from the mother ship.

[0012] Each sub-boat has a fastening flange on its top that mates with the corresponding connecting module.

[0013] A single connection module includes at least two davits, with the working end of each davit located in a receiving slot, allowing the corresponding sub-boat to be lifted or lowered via the davits; It also includes two sets of claw clamps. One set of claw clamps is arranged on one inner wall of the corresponding receiving slot, and the other set of claw clamps is arranged on the opposite inner wall of the corresponding receiving slot. Each set of claw clamps includes several positioning claw clamps arranged at even intervals. The positioning claw clamps extend horizontally to contact the bottom wall of the fastening fold, thereby limiting the corresponding sub-boat.

[0014] A working method for a highly seaworthy separable pentamaran based on the above-mentioned design includes the following steps: When the pentamaran is engaged in long-distance high-speed navigation, all the sub-ships are connected to the mother ship through corresponding connection modules to form a multi-hull mode. At this time, all the sub-ships are carried by the mother ship. When the pentamaran reaches the destination waters, the mother ship releases the pairs of sub-ships one by one. The released pairs of sub-ships are detached from the mother ship through the corresponding connecting modules, forming a split mode. After the detachment is completed, the two sub-ships in the corresponding pair of sub-ships can freely perform their tasks, while the mother ship remains floating.

[0015] The beneficial effects of this invention are as follows: This invention features a compact and rational structure, and is easy to operate. By setting up a detachable mother ship and multiple pairs of sub-ships, it can meet the needs of inter-island transportation by using a multi-hull mode for long-distance transportation between islands and a split-hull mode for short-distance navigation and landing near islands or lagoons. It has good stability and seakeeping, and can handle the transfer of personnel and goods in environments with clustered islands and varying terrain and berthing conditions near islands. It has multiple working scenarios and promotes the flow of personnel and materials between islands.

[0016] The present invention also has the following advantages: (1) By setting up a connecting bridge, the present invention can stably connect the mother ship and two pairs of sub-ships when the pentamaran is sailing at high speed. It can also achieve rapid connection and separation between the mother ship and the two pairs of sub-ships. At the same time, it can extend and widen the deck to facilitate the seating arrangement of the deck buildings. In addition, based on the passenger and cargo transport attributes of the pentamaran, the transfer of personnel through the connecting bridge can improve the convenience and safety of personnel movement.

[0017] (2) By setting up two pairs of sub-ships, the present invention can serve as the side hull of the mother ship, and the two sub-ships arranged on the same side of the mother ship are spaced apart, which can reduce wave-making interference at high speeds, thereby effectively improving the seakeeping and navigation stability of the pentamaran. At the same time, the design of four sub-ships is more suitable for the transportation needs of many small islands in the archipelago, and can go to multiple destination islands at the same time, which saves time and is more flexible. Furthermore, the layout of the fore-and-aft and relative positions of the four sub-ships can be designed and adjusted to a favorable position for wave-making interference between the mother ship and the sub-ships, so as to ensure that the pentamaran can sail at high speed. The four sub-ships can also improve the stability of the hull by designing the draft at the bow and stern, with the front pair of sub-ships and the rear pair of sub-ships having different drafts.

[0018] (3) The length-to-width ratio of each sub-boat in this invention is closer to that of a conventional small boat, and its buoyancy, stability and other properties are more suitable for independent navigation.

[0019] (4) The pentamaran of the present invention has the ability to detach from the mother ship to operate independently and to be retrieved and reconnected to the mother ship after the work is completed. The mother ship has the ability to release one or two pairs of pentamarans and anchor between islands and sail at low speed. It can meet the transportation needs of medium and long distance navigation of about 100 kilometers between islands and navigation and landing between small islands within the islands of about 15 kilometers. The overall crew capacity is not less than 60 people, the speed reaches more than 20 knots, the range is not less than 200 kilometers, and it has the ability to operate normally under sea state 4.

[0020] (5) The sub-boat of this invention can sail independently, with a maximum speed of not less than 8 knots, a crew of not less than 10 people, a cargo capacity of not less than 1 ton, and the ability to freely land on the island in the last mile; the bottom adopts a wear-resistant design and can be directly replaced if damaged.

[0021] (6) The working method of the present invention can achieve two-level transportation covering medium and long distances (about 100 kilometers) between islands and short distances (about 15 kilometers) within lagoon islands through multi-body mode, split mode and single-body mode. At the same time, the manufacturing cost of the sub-boats is low, and they can also serve as regular small boats to meet the daily travel and transportation needs of island residents when they are not attached to the mother boat. When the inter-island transfer tasks increase, the mother boat can be added. The sub-boats and the mother boat can be built separately, and the interfaces are standardized and can be combined as needed. After the five-hull boat operation mode matures, a mother boat-sub-boat scheduling APP can be formed to share information such as the location and connection status of the mother boat and the sub-boats in real time, and even extend to inter-island resource sharing to form a new form of inter-island transportation.

[0029] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] like Figures 1-6As shown, the highly seaworthy separable pentamaran of this embodiment includes a mother ship 1, on which two pairs of sub-ships 2 are configured. Each pair of sub-ships 2 includes two sub-ships symmetrically arranged relative to the mother ship 1. The deck of the mother ship 1 extends to both sides to form symmetrical connecting bridges 3. At least one receiving slot 9 is opened at the bottom of each connecting bridge 3. The receiving slots 9 are arranged one-to-one with the sub-ships. A connecting module is installed in each receiving slot 9. A single sub-ship is connected to the corresponding receiving slot 9 through the connecting module, or a single sub-ship is separated from the corresponding receiving slot 9 through the connecting module. In this embodiment, the pentamaran, by setting up connecting bridges 3, can stably connect the mother ship 1 and the two pairs of child ships 2 when the pentamaran is sailing at high speed. It can also enable the rapid connection and separation of the mother ship 1 and the two pairs of child ships 2. In this embodiment, the connecting bridges 3 and the deck of the mother ship 1 can adopt an integrated structure. The two connecting bridges 3 extend to the left and right sides of the mother ship respectively, which can extend and widen the deck to facilitate the seating arrangement of the deck buildings. In addition, based on the passenger and cargo transport attributes of the pentamaran, the transfer of personnel through the connecting bridges 3 can improve the convenience and safety of personnel movement.

[0031] The pentamaran of this embodiment, by setting up two pairs of sub-boats 2, can serve as the side hulls of the mother ship 1. The two sub-boats arranged on the same side of the mother ship 1 are spaced apart, which can reduce wave-making interference at high speeds, thereby effectively improving the seakeeping and navigation stability of the pentamaran. In addition, the length-to-beam ratio of each sub-boat is closer to that of a conventional small boat, and its buoyancy, stability and other properties are more suitable for independent navigation. At the same time, the design of four sub-boats is more suitable for the transportation needs of many small islands in an archipelago, and can simultaneously travel to multiple destination islands, which saves time and is more flexible. Furthermore, the layout of the fore-and-aft and relative positions of the four sub-boats can be designed and adjusted to a favorable position for wave-making interference between the sub-boats and the mother ship 1 and between the sub-boats themselves, so as to ensure that the pentamaran can sail at high speeds. The four sub-boats can also be designed with different drafts at the bow and stern, with the front pair of sub-boats 2 (i.e., the sub-boats 2 arranged near the bow) and the rear pair of sub-boats 2 (i.e., the sub-boats 2 arranged near the stern) selecting different drafts, which is more conducive to improving the stability of the hull.

[0032] like Figures 1-6 As shown, the mother ship 1 adopts a slender hull, which has good speed performance and a narrow Kelvin wave angle generated during high-speed navigation.

[0033] The daughter boat pairs 2 are arranged at intervals along the length of the mother ship 1, with one pair of daughter boat pairs 2 arranged at the stern of the mother ship 1. By making the position of the daughter boat pairs 2 as close as possible to the stern of the mother ship 1, they can form a favorable interference with the mother ship 1 during high-speed navigation and reduce the impact of waves during navigation.

[0034] To reduce slamming during navigation, each sub-boat adopts a single-angle hull form. This means the sub-boat's hull should have a slender, V-shaped profile, similar to a typical small boat, at least at the bow. This ensures high-speed performance at 20 knots when used as a side-hull. The transition towards the stern prioritizes layout, with the stern dedicated to passenger and cargo carrying. Sufficient width and depth, potentially in a U-shape, are provided in the mid-to-rear section to accommodate passenger and cargo needs. Furthermore, to ensure passenger comfort, its width is no less than 2 meters. The bottom of each sub-boat is covered with abrasion-resistant material. By setting the abrasion-resistant material coating layer, the bottom of the sub-boat can be protected when it is beached and brought ashore. In addition, the sub-boat should adopt a lightweight design to reduce the draft and facilitate beaching.

[0035] In this embodiment, the propulsion method of a single sub-boat adopts a retractable outboard motor; the retractable outboard motor is retracted when the corresponding sub-boat is connected to the mother ship 1, and is lowered for propulsion when the corresponding sub-boat is detached from the mother ship 1; in addition, the stern of a single sub-boat is provided with a concave section, thereby reserving a placement position for the retractable outboard motor, which not only protects the retractable outboard motor from being bumped, but the protruding parts on both sides of the concave section can also serve as a passage for personnel to disembark.

[0036] In addition, for the purpose of connection and release, the draft of a single sub-boat when it acts as a side hull of the pentamaran is shallower than the draft when the sub-boat sails independently, so as to facilitate the lifting and lowering of the corresponding sub-boat by the davit 6.

[0037] In this embodiment, the design and operation of individual sub-boats follow the principles of low cost, easy replacement, and standardization. Sub-boats can be mass-produced, and each sub-boat has the ability to dock with the mother ship 1. When conducting inter-island transportation, island personnel can equip themselves with sub-boats. When cargo and personnel need to be transported, island personnel submit their requests to the mother ship 1, which then travels between islands to connect different sub-boats. At the same time, when the mother ship 1 has a large capacity for both passengers and cargo and cannot fully transfer the four sub-boats originally connected to the mother ship 1, sub-boats from the destination can be dispatched to undertake the transportation task, thus forming the concept of "private cars at sea," improving the flexibility of the sub-boats, and enabling them to navigate freely to the islands in the vicinity of the lagoon for short distances, as well as dock with the mother ship 1 for long-distance transportation.

[0038] In this embodiment, a personnel and cargo transfer channel is provided inside the deck of the mother ship 1 where it connects to the connecting bridge 3. When sailing between islands, the personnel are located in the superstructure of the mother ship 1. After arriving near the destination, the cargo is transferred to the sub-ship through the cargo transfer channel, and the personnel walk from the deck through the connecting bridge 3 to the sub-ship through the personnel transfer channel and sit down before leaving the sub-ship to sail between islands.

[0039] Each sub-ship is equipped with a hatch cover 5 on its top, and a telescopic ladder 4 leading to the hatch cover 5 is installed inside the sub-ship. When the hatch cover 5 is opened, the telescopic ladder 4 extends, allowing personnel on the mother ship 1 to enter the corresponding sub-ship via the telescopic ladder 4.

[0040] In this embodiment, as Figure 3 As shown, the ship's holds from bow to stern are arranged in the following order: bow tip hold 14, anchor chain hold 15, storage hold 16, first cargo hold 11, equipment hold 20, engine room 24, second cargo hold 12, and third cargo hold 13. Among them, a first empty hold 17 is arranged below the anchor chain hold 15 and the storage hold 16. A second empty hold 18 is arranged next to the first empty hold 17 and below the first cargo hold 11. A first fuel tank 21 is arranged below the first cargo hold 11 and below the equipment hold 20. The first fuel tank 21 and the second empty hold 18 are spaced apart. A sea door 27 is installed on the ship's wall between the first fuel tank 21 and the second empty hold 18. The first fuel tank 21 is connected in sequence to the water tank 19 and the second fuel tank 22, which are arranged below the first cargo hold 11 and the equipment hold 20. The first fuel tank 21 and the second fuel tank 22 store fuel, and the main propulsion 10 is supplied with fuel through the fuel tank 28 installed in the engine room 24. Some of the equipment of the main propulsion 10 is arranged in the engine room 24, and its propeller is externally mounted. The rotation of the propeller generates a reaction force to propel the penthouse forward. Below the third cargo hold 13 is a steering gear compartment 25, in which a steering gear assembly is installed. The pentamaran uses the steering gear assembly to control the hull attitude, such as steering. The equipment compartment 24 houses the power distribution room 29, which supplies power to the ship's electrical equipment. The mother ship 1 has a superstructure on its deck, which includes a bridge 30 for the crew to pilot the pentagon and a passenger cabin 26 for accommodating passengers.

[0041] In this embodiment, conveyor belts are installed in the second cargo hold 12 and the third cargo hold 13 to realize the transportation and transfer of cargo inside the ship; in addition, a portion of the cargo can be pre-loaded into the sub-ship, so that such cargo does not need to be transferred.

[0042] like Figure 6 As shown, the pentamaran in this embodiment can also be connected to a pair of sub-ships 2 to become a trimaran.

[0043] like Figure 2 As shown, the top of each individual sub-boat is provided with a fastening flange 8 that mates with the corresponding connecting module. Figure 2In the diagram, the red-filled portion represents the fastening flange 8 of the corresponding sub-boat; each connecting module includes at least two davits 6, the working end of each davit 6 is located in the receiving groove 9, and the corresponding sub-boat is lifted or lowered by the davit 6; it also includes two sets of claw assemblies, one set of claw assemblies is arranged on one inner wall of the corresponding receiving groove 9, and the other set of claw assemblies is arranged on the opposite inner wall of the corresponding receiving groove 9, each set of claw assemblies includes several evenly spaced positioning claws 7, the positioning claws 7 extend horizontally, thereby contacting the bottom wall of the fastening flange 8, and thus limiting the corresponding sub-boat; Figure 2 In the middle, the blue dashed line represents the outline of the receiving slot 9.

[0044] In this embodiment, a davit 6 is provided for lifting or lowering the corresponding sub-boat. Each davit 6 is equipped with a steel cable and a winch.

[0045] When connecting a single sub-ship to the mother ship 1 via the connection module, the following steps are included: First, the steel cables of the two davits 6 are connected to the bow and stern lifting points of the corresponding sub-boats, respectively. Then, the winches of the two davits 6 are used simultaneously to lift the sub-boats, raising them into the receiving tank 9. When separating a single sub-boat from the mother ship 1, After the sub-boat is raised into position, the jaws of the positioning jaws 7 extend or retract, and by contacting the side wall of the sub-boat 2, make short-distance fine adjustments to the horizontal position of the sub-boat relative to the corresponding mounting slot 9 until it is perfectly aligned. Finally, the positioning claw 7 locks in place and extends below the fastening fold 8 to contact its bottom wall surface, thereby limiting the position of the sub-boat in the receiving slot 9.

[0046] When separating a single sub-ship from the mother ship 1 via the connection module, the following steps are included: First, all the jaws of the positioning jaws 7 retract simultaneously to release the restriction on the sub-boat, allowing the sub-boat to move locally within the corresponding mounting slot 9. Then, the steel cables of the two davits 6 are released and the winches are started to lower the sub-boat. The sub-boat floats under the corresponding connecting bridge 3 by its own buoyancy. The retractable outboard motor on the hull of the sub-boat is then lowered, thereby freeing the sub-boat from the constraint of the steel cables. Finally, after adjusting the direction, the dart can sail out from under the corresponding connecting bridge 3. After sailing out, in order to balance the stability of the mother ship 3 after releasing the dart, an airbag can be placed near the corresponding davit 6. After the dart sails out, the airbag is quickly inflated and opened, so that the mother ship 3 can rely on the airbag to generate buoyancy to safely anchor at the dock or drive at idle speed.

[0047] Based on the aforementioned highly seaworthy detachable pentamaran, this embodiment provides a working method, including the following steps: When the pentamaran is sailing at high speed over long distances, all the sub-ships 2 are connected to the mother ship 1 through the corresponding connection modules to form a multi-hull mode. At this time, all the sub-ships 2 are carried by the mother ship 1. The mother ship 1 can sail on routes with a distance of about 100 kilometers between islands and large waves, and can perform separation and connection operations at docks with relatively good landing conditions. Specifically, the four sub-ships act as the side hulls of the pentamaran, increasing roll damping and creating favorable interference with the mother ship 1 at high speeds; personnel can directly board the deck from the dock and sit in the passenger cabin 26; cargo can be transported to the mother ship 1 via cranes and other equipment located at the island docks, and the cargo is placed in the cargo hold to serve as ballast for the mother ship 1; at the same time, some cargo that needs to be transferred to the sub-ships can be placed in the sub-ships in advance to serve as ballast for the sub-ships.

[0048] When the pentamaran reaches the destination waters, the mother ship 1 releases the daughter ship pairs 2 one by one. Through the corresponding connecting modules, the released daughter ship pairs 2 are separated from the mother ship 1, forming a split mode. At this time, the mother ship 1 anchors or sails at low speed to wait. In order to balance the floating state of the pentamaran on the port and starboard sides, the two sub-boats in a single pair of sub-boats 2 are simultaneously connected to the mother ship 1, or the two sub-boats in a single pair of sub-boats 2 are simultaneously separated from the mother ship 1. After detachment, the two sub-ships contained in sub-ship pair 2 can freely perform their tasks, while the mother ship 1 remains afloat. Specifically, after the pentamaran berths at the dock, the cargo placed on the mother ship 1 is first transferred to the sub-ship via a conveyor belt. Subsequently, the sub-ship's driver and crew can enter the sub-ship one after another via the telescopic ladder 4. After the cargo and personnel have been transferred, the sub-ship is detached from the mother ship 1 through the connecting module. After detachment, the sub-ship can freely perform its tasks, while the mother ship 1 can maintain its afloat by using the dock or its own airbags.

[0049] After detaching from the mother ship, the sub-ship navigates independently in monohull mode. The sub-ship is capable of landing on islands. Since the landing sites are mostly scattered small islands in an archipelago with generally poor landing conditions, the landing method is beaching. The sub-ship's transfer distance is about 15 kilometers, and its endurance requirements are relatively low. The retractable outboard motor can meet its propulsion needs. In monohull mode, the corresponding retractable outboard motor is deployed and drives the sub-ship. When the sub-ship is connected to the mother ship 1, the retractable outboard motor is retracted, which can reduce the impact of water flow on the retractable outboard motor when the pentamaran is traveling at high speed and can also play a role in drag reduction.

[0050] The working method of this embodiment, through multi-body mode, split mode, and single-body mode, can achieve two-level transportation covering medium-to-long distances (about 100 kilometers) between islands and short distances (about 15 kilometers) within lagoon islands. At the same time, the manufacturing cost of the sub-boats is low, and they can also serve as regular small boats to meet the daily travel and transportation needs of island residents when not attached to the mother ship 1. When the inter-island transfer tasks increase, the mother ship 1 can be added. The sub-boats and the mother ship 1 can be built separately, with standardized interfaces, and can be combined as needed. After the five-hull boat operation mode matures, a mother ship-sub-boat scheduling APP can also be formed to share information such as the location and connection status of the mother ship 1 and the sub-boats in real time, and even extend to inter-island resource sharing, forming a new form of inter-island transportation.
