Description

Technical Field

[0001] This invention relates to the field of marine technology, and more particularly to a harbor mooring device and a vessel. Background Technology

[0002] Currently, there are basically two types of mooring systems in domestic harbors: one is the fixed coastal type, where a fixed quay crane is built directly on the coast for berthing, and small boats need to travel to the coast where there is a berth for transfer. However, fixed coastal harbors do not have the characteristic of accompanying ships and cannot meet the requirements for safe berthing and transfer between small boats and the mother ship during navigation. The other type is the cabin-pool type, which utilizes the lower deck of the ship to create an inner pool compartment that extends to the sea and is large enough to accommodate small boats, allowing small boats to berth and transfer directly inside the compartment.

[0003] Without the protection of a harbor or basin during navigation, the direct berthing and transshipment of small boats to the mother ship involves extremely strong impacts from the rise and fall of waves, posing significant potential risks to every operation by the crew and resulting in poor safety. For example, the connection or disconnection of mooring lines and the transshipment process require a high level of skill and experience from the operators, with the potential for injury due to the swaying of the small boat. The use of compartments and pools increases the difficulty and cost of hull construction. Furthermore, if a sea-opening compartment design is adopted, the bottom of the hull will be hollowed out, directly affecting the strength and rigidity of the hull structure and reducing its stability. Summary of the Invention

[0004] The purpose of this invention is to provide a harbor mooring device and vessel that can safely berth and transfer small boats to a mother ship during navigation, avoiding direct berthing and transfer between the small boat and the mother ship, reducing risks, construction difficulty and cost, and ensuring the strength, rigidity and stability of the hull structure.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A harbor mooring device, comprising:

[0007] Two first berths and at least one second berth are arranged along a first direction, with at least one second berth located between the two first berths. One end of each of the first and second berths is rotatably connected to the hull about an axis parallel to the first direction, and the other end is respectively lockable to the hull.

[0008] Two first baffles and at least one second baffle, the two first baffles being disposed corresponding to the two first berths, the first baffles being disposed on the side of the first berth facing the second berth, the second baffles being disposed on both sides of the second berth along the first direction;

[0009] When the first and second berths are locked to the hull, they are housed within the hull. When the first and second berths are unlocked from the hull, they rotate outwards from the hull, forming a berth on the side of the first berth facing away from the second berth. The first berth, the second berth, and the first and second baffles between them form a harbor. When multiple second berths are provided, two adjacent second berths and the second baffle between them form a harbor.

[0010] In some possible implementations, a plurality of pulley blocks are also included, each corresponding to one of the first and second berths. Each pulley block includes a steel cable, a winch power unit, a fixed pulley block, and a movable pulley block. The winch power unit and the fixed pulley block are both located on the hull, and the movable pulley block is located on the first or second berth. The steel cable is pulled out from the winch power unit, wound around the fixed pulley block and the movable pulley block, and is correspondingly fixed to the first or second berth.

[0011] In some possible implementations, both the first and second berths are box-shaped structures, the interior of which can be filled with water.

[0012] In some possible implementations, both the first baffle and the second baffle are provided with pressure relief holes.

[0013] In some possible implementations, the width direction of the first berth and the second berth is the first direction, one end of the first berth and the second berth in the length direction is rotatably connected to the hull, and the rotation center lines of the first berth and the second berth are collinear, and the other end can be locked to the hull, and the length of the first berth is greater than the length of the second berth.

[0014] In some possible implementations, both the first and second berths are provided with anti-collision plates on both sides along the first direction.

[0015] In some possible implementations, the first berth and the second berth are each provided with a first socket, and the hull is provided with a plurality of second sockets. The first sockets and the second sockets correspond one-to-one, and a safety pin is inserted into the first socket and the second socket to lock the first berth or the second berth to the hull.

[0016] In some possible implementations, when the first and second berths are in the retracted state, part of them are located outside the hull and the other part is housed inside the hull.

[0017] In some possible implementations, the top surfaces of both the first and second berths are provided with a walking passage that communicates with the hull.

[0018] A vessel includes a hull and a harbor mooring apparatus as described above, wherein a first berth and a second berth are arranged along a first direction, and one end of the first berth and the second berth are respectively rotatably connected to the hull about an axis parallel to the first direction, and the other end is respectively lockable to the hull.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a harbor mooring device and vessel. In the initial state, both the first and second berth bridges are locked to the hull, flipped up, and stored within the hull. In the open state, the two berth bridges are unlocked from the hull and flipped outwards. When the berth bridges are fully lowered to their lowest position, two safe harbors and two outer mooring positions are formed, for a total of four mooring locations. The first and second berth bridges, the first and second baffles, and the hull form a multi-faceted protected berthing harbor. It features multiple berths, high berthing and transshipment efficiency, and the intermediate harbor berths of the harbor mooring device have variable spatial characteristics, accommodating small boats of different classes for berthing and transshipment in adverse sea conditions. It can accommodate different numbers of small boats according to different working conditions and boat sizes, demonstrating good adaptability.

[0021] The harbor mooring system, installed on the hull, enables safe berthing and transshipment of small boats to the mother ship during navigation. The deployment of the first and second berth bridges creates berths and harbor positions for small boats, capable of handling multiple small boats simultaneously berthing and transshipment even in adverse sea conditions. Personnel can safely and smoothly perform berthing and transshipment operations directly within the harbor in rough seas, reducing risks to crew operations and ensuring high safety. The hull also features retractable and storeable first and second berth bridges, which can be stored at the stern during navigation without affecting navigation, greatly improving the portability, simplicity, reliability, and multi-functionality of the harbor mooring system. It avoids the use of open-bottomed pools, eliminating the need to hollow out the hull bottom, ensuring the strength and rigidity of the hull structure, guaranteeing stability, solving safety and reliability issues during berthing and transshipment at sea, and reducing shipbuilding difficulty and cost.

[0029] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1-5 As shown, this embodiment provides a vessel, including a hull 100 and a harbor mooring device. This embodiment also provides a harbor mooring device, including two first berth bridges 1, two first baffles 3, at least one second berth bridge 2, and at least one second baffle 4. The two first berth bridges 1 and at least one second berth bridge 2 are arranged along a first direction, with the at least one second berth bridge 2 located between the two first berth bridges 1. One end of each of the first berth bridges 1 and 2 is rotatably connected to the hull 100 about an axis parallel to the first direction, and the other end is lockable to the hull 100. The two first baffles 3 are correspondingly arranged to the two first berth bridges 1, with the first baffles 3 located on the side of the first berth bridge 1 facing the second berth bridge 2. The second baffles 4 correspond one-to-one with the second berth bridges 2, and are arranged on both sides of the second berth bridge 2 along the first direction.

[0033] When the first berth bridge 1 and the second berth bridge 2 are locked to the hull 100, the first berth bridge 1 and the second berth bridge 2 are housed within the hull 100. When the first berth bridge 1 and the second berth bridge 2 are unlocked to the hull 100, the first berth bridge 1 and the second berth bridge 2 rotate outward from the hull 100. The side of the first berth bridge 1 away from the second berth bridge 2 forms a berth. The first berth bridge 1, the second berth bridge 2, and the first baffle 3 and the second baffle 4 between them form a harbor. When there are multiple second berth bridges 2, two adjacent second berth bridges 2 and the second baffle 4 between them form a harbor.

[0034] In this embodiment, one second berth bridge 2 is provided as an example for illustration. In other embodiments, two or more second berth bridges 2 may be provided, without limitation.

[0035] In the initial state, both first berth bridges 1 and second berth bridge 2 are locked to the hull 100, flipped up, and stored within the hull 100. In the open state, both first berth bridges 1 and second berth bridge 2 are unlocked from the hull 100 and flipped outwards. When the berth bridges are fully lowered to their lowest position, two safe harbors and two outer mooring positions are formed, for a total of four mooring locations. First berth bridge 1, second berth bridge 2, first baffle 3, and second baffle 4, together with the hull 100, form a multi-faceted protected berthing harbor.

[0036] For example, the first direction is left and right. The first baffle 3 on the left and the corresponding first berth bridge 1 are fixed together to form a left berth and a left berthing bay. The second berth bridge 2 and the second baffle 4 are fixed together to form a left berthing bay and a right berthing bay. The first berth bridge 1 on the right and the corresponding first baffle 3 are fixed together to form a right berthing bay and a right berth. Specifically, the number of small boats 200 can be moored in the bay according to the size of the small boats 200. When the waves are not strong (such as in sea state 0-2), four berths can be used simultaneously for berthing and transfer operations. When the waves are strong (such as in sea state 3-4), the two middle bays can be protected by the first berth bridge 1, the second berth bridge 2, and the first baffle 3 and the second baffle 4, allowing for safe berthing and transfer operations. When the small boat 200 to be moored is large, the second berth bridge 2 can be independently flipped up, and the two first berth bridges 1 form a large bay, which can accommodate larger small boats 200. It features multiple berths, high berthing and transshipment efficiency, and the intermediate harbor berths of the harbor mooring system have variable space characteristics, meeting the berthing and transshipment needs of small boats of different classes under adverse sea conditions. It can accommodate different numbers of small boats 200 according to different needs such as working conditions and the size of the small boats 200, demonstrating good adaptability.

[0037] The harbor mooring system is installed on the hull 100, enabling safe berthing and transfer between the small boat 200 and the mother ship during navigation. When the first berth bridge 1 and the second berth bridge 2 are deployed, they form a harbor and berth for the small boat 200, capable of handling multiple small boats 200 simultaneously for berthing and transfer even in adverse sea conditions. Personnel can safely and smoothly perform berthing and transfer operations directly within the harbor in adverse sea conditions, reducing the risk to crew members and ensuring high safety. Simultaneously, the hull 100 has the function of retracting and storing the first berth bridge 1 and the second berth bridge 2. During navigation, they can be retracted or stored at the stern of the hull 100 without affecting navigation, greatly improving the portability and simple, reliable, and multifunctional nature of the harbor mooring system. By avoiding the use of a hull-through-the-sea compartment, there is no need to hollow out the bottom of the hull 100, which ensures the structural strength and rigidity of the hull 100, guarantees the stability of the hull 100, solves the safety and reliability issues during berthing and transshipment at sea, and reduces the difficulty and cost of ship construction.

[0038] For example, the first berth bridge 1 and the second berth bridge 2 are connected to the stern of the hull 100, which has very little impact on the construction of the hull 100. At the same time, the harbor mooring device has a clever and simple structure, low construction cost, and can be widely promoted and applied.

[0039] Two first berths 1 and one second berth 2 are connected to the hull 100 via three independent pivots 6. The harbor mooring device also includes multiple pulley blocks 5. In this embodiment, three pulley blocks 5 are included, each corresponding to one of the two first berths 1 and one second berth 2. The three pulley blocks 5 control the three berths to rotate around the pivots 6, so as to rotate up and down relative to the hull 100. Specifically, the pulley block 5 includes a steel cable 51, a winch power unit, a fixed pulley block 53, and a movable pulley block 52. The winch power unit and the fixed pulley block 53 are both located on the hull 100, and the movable pulley block 52 is located on either the first berth 1 or the second berth 2. The steel cable 51 is pulled out from the winch power unit, wound around the fixed pulley block 53 and the movable pulley block 52, and is correspondingly fixed to the first berth 1 or the second berth 2.

[0040] The first berth bridge 1 and the second berth bridge 2 are respectively provided with a first socket, and the hull 100 is provided with multiple second sockets. The first sockets and the second sockets correspond one to one. The safety pin 8 is inserted into the first socket and the second socket to lock the first berth bridge 1 or the second berth bridge 2 to the hull 100.

[0041] Open the safety lock and activate the winch power unit of the corresponding berth, such as the first berth 1, to release the steel cable 51. Under the action of gravity, the first berth 1 will slowly open outwards as the steel cable 51 is released. The mechanical structure allows for rapid release of the berths, making operation convenient, stable, reliable, efficient, and flexible.

[0042] Both the first berth crane 1 and the second berth crane 2 are box-shaped structures with hollow interiors. The interiors can be filled with water, and the weight of the water added can be controlled according to changes in sea conditions to adjust the stability between the berth crane and the vessel 100. This independent hollow berth crane design significantly reduces the load on the vessel 100, while also allowing for water injection into the hollow spaces of the berth cranes to improve their static stability and provide safety for berthing.

[0043] The top surfaces of both the first berth bridge 1 and the second berth bridge 2 are equipped with walking passageways 11 that connect to the hull 100. Personnel can directly carry out transshipment operations on the walking passageways 11, which is low-cost, simple to operate, and safe and reliable.

[0044] Both the first baffle 3 and the second baffle 4 are equipped with pressure relief holes 31, which can effectively attenuate and block the impact of bottom wave fluctuations on the small boat 200 in the harbor.

[0045] The width direction of the first berth bridge 1 and the second berth bridge 2 is the first direction. One end of the first berth bridge 1 and the second berth bridge 2 is rotatably connected to the hull 100 in the length direction, and the rotation center lines of the first berth bridge 1 and the second berth bridge 2 are collinear. The other end can be locked to the hull 100. The length of the first berth bridge 1 is greater than the length of the second berth bridge 2, which improves the protection of the berthing in the harbor.

[0046] Both the first berthing bridge 1 and the second berthing bridge 2 are equipped with anti-collision plates 7 on both sides along the first direction, which can effectively reduce the collision between the small boat 200 and the first berthing bridge 1 or the second berthing bridge 2 during the berthing process and avoid damage to the small boat 200.

[0047] When the first berth bridge 1 and the second berth bridge 2 are in the retracted state, both the first berth bridge 1 and the second berth bridge 2 are partially located outside the hull 100 and the other part is accommodated inside the hull 100, resulting in a more compact structure.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
