Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a harbor mooring device and a ship. Background Art

[0002] At present, there are basically two types of domestic harbor mooring devices: one is the coastal fixed type: a fixed shore bridge berth is built directly on the coast, and the small boat needs to sail to the coast with a berth for transfer. However, the coastal fixed harbor does not have the characteristics of following the ship, and cannot meet the requirements of safe berthing and transfer between the small boat and the mother ship during the voyage. The other is the cabin pool type: using the lower deck cabin inside the ship to open an inner pool cabin that runs through the sea surface and is large enough to accommodate the small boat in and out, the small boat directly berths and transfers in the cabin.

[0003] Without the protection of a harbor or port during the voyage, the boat will directly dock and transfer with the mother ship due to the ups and downs of the waves, which will cause a very strong drop impact on every operation of the crew, and the safety is poor. For example, when connecting or releasing the cable docking and the crew transfer process, the skills and experience requirements of the operators are quite high, and the swing of the boat may cause personal injury. The cabin tank type increases the difficulty of hull construction and increases the construction cost of the hull. At the same time, if the cabin tank method with the cabin connected to the sea is adopted, the bottom of the hull will be directly hollowed out, which will directly affect the strength and rigidity of the hull structure and reduce the stability of the hull. Summary of the invention

[0004] The object of the present invention is to provide a harbor mooring device and a ship, which can meet the requirements of safe berthing and transfer between a small boat and a mother ship during navigation, avoid the small boat directly berthing and transfer between the mother ship hull, reduce risks, reduce construction difficulty and cost, and ensure the strength, rigidity and stability of the hull structure.

[0009] When the first mooring bridge and the second mooring bridge are locked to the hull, the first mooring bridge and the second mooring bridge are stored in the hull; when the first mooring bridge and the second mooring bridge are unlocked from the hull, the first mooring bridge and the second mooring bridge rotate toward the outside of the hull, and the side of the first mooring bridge away from the second mooring bridge forms a berth, and the first mooring bridge, the second mooring bridge and the first baffle and the second baffle therebetween form a harbor, and when multiple second mooring bridges are provided, two adjacent second mooring bridges and the second baffle therebetween form a harbor.

[0010] In some possible embodiments, it further includes a plurality of pulley groups, which are arranged in a one-to-one correspondence with the first mooring bridge and the second mooring bridge, and the pulley groups include a steel cable, a winch power group, a fixed pulley group and a movable pulley group. The winch power group and the fixed pulley group are both arranged on the hull, and the movable pulley group is arranged on the first mooring bridge or the second mooring bridge. The steel cable is pulled out from the winch power group, wound around the fixed pulley group and the movable pulley group, and fixed on the first mooring bridge or the second mooring bridge accordingly.

[0011] In some possible implementations, the first mooring bridge and the second mooring bridge are both boxes, and water can be filled into the boxes.

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

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

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

[0015] In some possible implementations, the first mooring bridge and the second mooring bridge are respectively provided with a first socket, 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 plugged into the first socket and the second socket to lock the first mooring bridge or the second mooring bridge to the hull.

[0016] In some possible implementations, when the first mooring bridge and the second mooring bridge are in the stowed state, part of them is located outside the hull, and the other part is accommodated inside the hull.

[0017] In some possible implementations, the top surfaces of the first berthing bridge and the second berthing bridge are both provided with walking passages connected to the hull.

[0032] like Figure 1-Figure 5 As shown, this embodiment provides a ship, including a hull 100 and a harbor mooring device. This embodiment also provides a harbor mooring device, including two first mooring bridges 1, two first baffles 3, at least one second mooring bridge 2 and at least one second baffle 4. The two first mooring bridges 1 and the at least one second mooring bridge 2 are arranged along the first direction, and the at least one second mooring bridge 2 is located between the two first mooring bridges 1. One end of the first mooring bridge 1 and the second mooring bridge 2 are respectively connected to the hull 100 by rotation around an axis parallel to the first direction, and the other end can be locked to the hull 100. The two first baffles 3 are arranged corresponding to the two first mooring bridges 1, and the first baffles 3 are arranged on the side of the first mooring bridge 1 facing the second mooring bridge 2. The second baffles 4 correspond to the second mooring bridges 2 one by one, and the second baffles 4 are arranged on both sides of the second mooring bridge 2 along the first direction.

[0033] When the first mooring bridge 1 and the second mooring bridge 2 are locked to the hull 100, the first mooring bridge 1 and the second mooring bridge 2 are stored in the hull 100. When the first mooring bridge 1 and the second mooring bridge 2 are unlocked from the hull 100, the first mooring bridge 1 and the second mooring bridge 2 rotate toward the outside of the hull 100, and the first mooring bridge 1 forms a berth on the side away from the second mooring bridge 2. The first mooring bridge 1, the second mooring bridge 2 and the first baffle 3 and the second baffle 4 therebetween form a harbor. When multiple second mooring bridges 2 are provided, two adjacent second mooring bridges 2 and the second baffle 4 therebetween form a harbor.

[0034] In this embodiment, one second mooring bridge 2 is used as an example for illustrative description. In other embodiments, two or more than three second mooring bridges 2 may be provided without limitation.

[0035] In the initial state, the two first mooring bridges 1 and the second mooring bridge 2 are locked to the hull 100, turned up and stored in the hull 100. In the open state, the two first mooring bridges 1 and the second mooring bridges 2 are unlocked from the hull 100 and turned outward from the hull 100. When the mooring bridges are fully lowered and reach the lowest limit, two safe harbors and two outer mooring positions can be formed, with a total of four mooring positions. The first mooring bridge 1, the second mooring bridge 2, the first baffle 3, the second baffle 4 and the hull 100 form a berthing bay with multi-faceted protection.

[0036] Exemplarily, the first direction is the left-right direction, the first baffle 3 on the left side and the corresponding first berthing bridge 1 are fixed as one body to form a left berth and a left berthing bay, the second berthing bridge 2 and the second baffle 4 are fixed as one body to form a left berthing bay and a right berthing bay, and the first berthing bridge 1 on the right side and the corresponding first baffle 3 are fixed as one body to form a right berthing bay and a right berth. Specifically, a corresponding number of boats 200 can be docked in the harbor according to the size of the boat 200. When the waves are not strong (such as when the sea conditions are 0-2), four berthing positions can be used at the same time for berthing and transshipment operations. When the waves are strong (such as when the sea conditions are 3-4), the two middle bays can be safely berthed and transshipped under the protection of the first berthing bridge 1, the second berthing bridge 2, the first baffle 3, and the second baffle 4. When the boat 200 to be berthed is large in size, the second berthing bridge 2 can be independently turned up, and the two first berthing bridges 1 form a large harbor, which can dock boats 200 of larger specifications. It has multiple berths, high berthing and transshipment efficiency, and the middle berth of the harbor mooring device has the characteristic of variable space, which can meet the berthing and transshipment of small boats 200 of different levels in severe sea conditions. It can park different numbers of small boats 200 according to different needs such as working conditions and the size of the small boats 200, and has good adaptability.

[0037] The harbor mooring device is installed on the hull 100, and can meet the requirements of safe berthing and transfer between the small boat 200 and the mother ship during navigation. After the first berth 1 and the second berth 2 are deployed, the small boat 200 can be moored in the harbor and berth, which can cope with severe sea conditions and meet the requirements of multiple small boats 200 for berthing and transfer at the same time. Personnel can carry out berthing and transfer operations safely and smoothly directly in the harbor under severe sea conditions, which reduces the risk of operation to the crew and has high safety. At the same time, the hull 100 has the function of retracting, releasing and storing the first berth 1 and the second berth 2, which will be retracted and stored at the stern of the hull 100 during navigation, without causing any impact on navigation, greatly improving the portability and simple and reliable versatility of the harbor mooring device. Avoiding the use of a tank method in which the cabin is connected to the sea, there is no need to hollow out the bottom of the hull 100, which ensures the strength and rigidity of the hull 100 structure, ensures the stability performance of the hull 100, solves the safety and reliability of berthing and transshipment during navigation, and reduces the difficulty and cost of ship construction.

[0038] For example, the first mooring bridge 1 and the second mooring 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 an ingenious and simple structure and low construction cost, and can be widely promoted and applied.

[0039] The two first berthing bridges 1 and the second berthing bridge 2 are connected to the hull 100 through three independent rotating shafts 6, respectively. The harbor mooring device also includes a plurality of pulley blocks 5. In this embodiment, three pulley blocks 5 are included, which are arranged one-to-one with the two first berthing bridges 1 and the second berthing bridge 2. The three pulley blocks 5 control the three berthing bridges to rotate around the rotating shafts 6 one-to-one, so as to flip up and down relative to the hull 100. Specifically, the pulley block 5 includes a steel cable 51, a winch power group, a fixed pulley block 53 and a movable pulley block 52. The winch power group and the fixed pulley block 53 are both arranged on the hull 100, and the movable pulley block 52 is arranged on the first berthing bridge 1 or the second berthing bridge 2. The steel cable 51 is pulled out from the winch power group, wound around the fixed pulley block 53 and the movable pulley block 52, and fixed to the first berthing bridge 1 or the second berthing bridge 2 accordingly.

[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 a plurality of second sockets, the first sockets and the second sockets correspond one to one, and the safety pin 8 is plugged 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 latch, start the winch power group of the corresponding mooring bridge, such as the first mooring bridge 1, to release the steel cable 51. Under the action of gravity, the first mooring bridge 1 will slowly open outwards following the release of the steel cable 51. The mechanical structure can quickly release the mooring bridge, is easy to operate, runs stably and reliably, and has high efficiency and flexibility.

[0042] The first mooring bridge 1 and the second mooring bridge 2 are both boxes with hollow interiors. Water can be injected into the boxes, and the weight of the injected water can be controlled according to changes in sea conditions to adjust the stability between the mooring bridge and the hull 100. The independent hollow mooring bridge design greatly reduces the load on the hull 100, and can also inject water into the hollow space of the mooring bridge according to changes in sea conditions to improve the static stability of the mooring bridge and provide safety for berthing.

[0043] The top surfaces of the first berthing bridge 1 and the second berthing bridge 2 are both provided with a walking passage 11 connected to the hull 100 , and personnel can directly perform transshipment operations on the walking passage 11 , which is low in cost, simple in operation, safe and reliable.

[0044] The first baffle plate 3 and the second baffle plate 4 are both provided with pressure relief holes 31, which can effectively attenuate and block the impact of the bottom waves on the small boat 200 in the harbor.

[0045] The width direction of the first mooring bridge 1 and the second mooring bridge 2 is the first direction, one end of the first mooring bridge 1 and the second mooring bridge 2 in the length direction is rotatably connected to the hull 100, and the rotation center lines of the first mooring bridge 1 and the second mooring bridge 2 are collinear, and the other end can be locked to the hull 100, and the length of the first mooring bridge 1 is greater than that of the second mooring bridge 2, thereby improving the protection of the berthing bay.

[0046] Anti-collision plates 7 are provided on both sides of the first berthing bridge 1 and the second berthing bridge 2 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, thereby avoiding damage to the small boat 200.

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

[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 embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
