Description

Technical Field

[0001] This utility model belongs to the field of shore power application technology for ships, and more specifically, relates to a large-capacity shore power access system suitable for double-row cruise ships berthed at inland river terminals. Background Technology

[0002] With the booming development of the cruise market, tourism consumption demand along the Yangtze River continues to rise, and cruise tourism has become an important engine for regional economic growth. Many important port cities along the Yangtze River are accelerating the layout and construction of cruise centers to meet the increasing demand for cruise ship berthing. However, with the increase in the number of cruise ships, many ports are seeing two cruise ships berthing side-by-side, which presents new challenges for accessing shore power for cruise ships.

[0003] Currently, there are two main methods for shore power access when two cruise ships berth side-by-side. The first method involves connecting only the cruise ship that berths first. However, this method does not comply with current port regulations for shore power access for vessels, which require each berthed ship to have shore power access to reduce the use of fuel-powered generators during berthing, thereby reducing pollutant emissions and protecting the port and surrounding environment. The second method involves connecting the shore power to the cruise ship that berths later, achieved by crossing the shore power cable across the first berthed ship. Since the shore power capacity of a single cruise ship is typically above 500kW at low voltage, multiple large-section, heavy cables need to be laid simultaneously. However, this method has several problems: the large power capacity of cruise ships, the large number and weight of shore power cables, and the considerable length crossing the preceding cruise ship make the connection operation complex and difficult. It also may pose safety hazards to the first berthed cruise ship and increase the difficulty and cost of cable management. Therefore, there is an urgent need for a new technological solution that can efficiently, safely, and in compliance with regulations address the shore power access issue when two cruise ships are berthed side-by-side, in order to promote the sustainable development of the cruise tourism industry while meeting the dual requirements of environmental protection and operational efficiency. Utility Model Content

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a high-capacity shore power access system suitable for two cruise ships berthing side-by-side at inland river terminals. By setting up a parallel circuit between the first and second shore power access devices, it enables simultaneous power supply from the shore side to two cruise ships. This not only improves the flexibility and reliability of power transmission but also allows for reasonable load allocation based on the actual power demand of each cruise ship, effectively avoiding overload on a single line and extending equipment lifespan. Simultaneously, the system reduces investment in shore-side equipment and line laying costs, shortens shore power access preparation time, and significantly improves operational efficiency and economy. Furthermore, the system employs a symmetrically arranged shore power plug-in box and conversion busbar structure, coupled with a manual switching switch, allowing for quick selection of the appropriate shore power connection path based on the port or starboard berthing status of the cruise ship, simplifying the operation process and improving operational efficiency.

[0005] To achieve the above objectives, this utility model provides a high-capacity shore power access system suitable for double-row berthed cruise ships at inland river terminals. The system includes a first shore power cable winch and a second shore power cable winch arranged side-by-side at the inland river terminal; a first cruise ship and a second cruise ship berthed side-by-side at the terminal berth; and a first shore power access device and a second shore power access device respectively installed in the power distribution rooms of the first and second cruise ships.

[0006] The first shore power access device includes a first shore power plug-in box, a second shore power plug-in box, a first distribution panel, a first busbar trunking, a second busbar trunking, and a third busbar trunking. The first shore power plug-in box and the second shore power plug-in box are symmetrically and fixedly installed on the port and starboard sides of the first cruise ship's power distribution room. The first shore power plug-in box is connected to the second shore power plug-in box and the first distribution panel through the first busbar trunking and the second busbar trunking, respectively. The first distribution panel is connected to the second shore power plug-in box through the third busbar trunking.

[0007] The second shore power access device includes a third shore power plug-in box, a fourth shore power plug-in box, a second distribution panel, a fourth busbar trunking, a fifth busbar trunking, and a sixth busbar trunking. The third shore power plug-in box and the fourth shore power plug-in box are symmetrically and fixedly installed on the port and starboard sides of the second cruise ship power distribution room. The third shore power plug-in box is connected to the fourth shore power plug-in box and the second distribution panel through the fourth busbar trunking and the fifth busbar trunking, respectively. The second distribution panel is connected to the fourth shore power plug-in box through the sixth busbar trunking.

[0008] The first shore power cable winch and the second shore power cable winch are respectively connected to the first shore power access device through their respective shore power composite cables. The first shore power access device and the second shore power access device are connected through the shore power composite cable to form a parallel power supply circuit, so as to realize that the two shore power cable winches can supply power to the first cruise ship and the second cruise ship in parallel and independently.

[0009] Furthermore, the first shore power plug box is provided with a first conversion busbar and two first plug-in components inside. One end of the first plug-in component is connected to the first conversion busbar, and the other end of the first conversion busbar is connected to the second shore power plug box and the first distribution panel through the first busbar trunking and the second busbar trunking, respectively.

[0010] Furthermore, the second shore power connection box is provided with a second conversion busbar and two second connectors. One end of the second conversion busbar is connected to the first busbar trunking and the third busbar trunking respectively, and the other end is connected to the two second connectors respectively.

[0011] Furthermore, the third shore power connection box is equipped with a third conversion busbar and two third connectors. One end of the third connector is connected to the third conversion busbar, and the other end of the third conversion busbar is connected to the fourth shore power connection box and the second distribution panel through the fourth busbar trough and the fifth busbar trough, respectively.

[0012] Furthermore, the fourth shore power connection box is equipped with a fourth conversion busbar and two fourth connectors. One end of the fourth conversion busbar is connected to the fourth busbar trough and the fifth busbar trough respectively, and the other end is connected to the two fourth connectors.

[0013] Furthermore, an optical cable is connected between the first conversion busbar, the second conversion busbar, and the first distribution panel, and an optical cable is connected between the first distribution panel and the second conversion busbar;

[0014] Optical cables are connected between the third and fourth conversion busbars and the second distribution panel, and optical cables are also connected between the second distribution panel and the fourth conversion busbar.

[0015] Furthermore, based on the actual berthing status of the first and second cruise ships on their port or starboard sides, the corresponding shore power connection path is selected by operating the switches of the first, second, third, and fourth transfer busbars. This allows the shore power and signals from the dock to be connected to the cabin power distribution rooms of the first and second cruise ships along the selected path, thereby providing continuous and stable power support during the cruise ships' berthing period.

[0016] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0017] (1) The large-capacity shore power access system of this utility model enables shore power to supply power to the first cruise ship and the second cruise ship simultaneously by setting up a parallel circuit between the first shore power access device and the second shore power access device, which significantly improves the flexibility and reliability of power transmission. Secondly, the parallel power supply method realizes the reasonable distribution of power load. The two cruise ships can obtain the corresponding power from the parallel circuit according to their own real-time power demand, which effectively avoids the phenomenon of overload due to excessive load of a single power supply line and extends the service life of equipment such as cables and connectors. In addition, compared with laying shore power lines separately for the two cruise ships, this parallel form reduces the investment in shore equipment and the cost of laying lines, and reduces construction and operation costs. At the same time, the parallel connection structure enables the two cruise ships to quickly obtain sufficient power supply after docking, shortens the preparation time for shore power access, and improves the operating efficiency of the cruise ships.

[0018] (2) The large-capacity shore power access system of this utility model, through the symmetrical arrangement of shore power plug boxes and conversion busbar structure, combined with manual switching switch, can quickly select the appropriate shore power connection path according to the actual situation of the cruise ship berthing on the port or starboard side, which significantly simplifies the shore power access operation process, shortens the connection time, and improves the overall operation efficiency. In addition, the shore power composite cable integrates power transmission and signal transmission functions. Combined with the optical cable connection between the conversion busbar and the distribution panel, it can realize high-speed and stable transmission of control signals and monitoring data, and improve the intelligence level and operational reliability of the system.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1-7As shown, this utility model provides a high-capacity shore power access system suitable for double-row berthing of cruise ships at an inland river terminal. It includes a first shore power cable winch 1, a second shore power cable winch 2, a first cruise ship 3, a second cruise ship 4, a first shore power access device 5, and a second shore power access device 6. The first shore power cable winch 1 and the second shore power cable winch 2 are installed side-by-side at the inland river terminal, serving as key equipment for shore-side power supply. Their retractable cables can be flexibly adjusted according to the berthing distance of the cruise ships, ensuring a stable connection with the vessels. The first cruise ship 3 and the second cruise ship 4 are berthed side-by-side at the terminal berth. The first cruise ship 3 is equipped with… The electrical room of the first shore power access device 5 is installed, and the electrical room of the second cruise ship 4 is equipped with a second shore power access device 6. The first shore power cable winch 1 and the second shore power cable winch 2 are connected to the first shore power access device 5 through a shore power composite cable to transmit power from the shore power grid to the power distribution system of the first cruise ship 3. At the same time, the first shore power access device 5 and the second shore power access device 6 are connected through a shore power composite cable, so that the first shore power cable winch 1 and the second shore power cable winch 2 can independently supply power to the power distribution system of the first cruise ship 3 and the power distribution system of the second cruise ship 4, thereby completing the access of the shore power system of the two ships side by side.

[0029] Furthermore, the first shore power access device 5 includes a first shore power connector box 51 and a second shore power connector box 52 symmetrically and fixedly installed on the port and starboard sides of the power distribution room of the first cruise ship 3. Inside the first shore power connector box 51, there is a first conversion busbar 511 and two first connectors 512. One end of the first connector 512 is connected to the first conversion busbar 511, while the other end of the first conversion busbar 511 is connected to the second shore power connector box 52 and the first distribution panel 53 respectively through the first busbar 54 and the second busbar 55. The first distribution panel 53 is connected to the second shore power connector box 52 through the third busbar 56.

[0030] Furthermore, the second shore power connection box 52 is equipped with a second conversion busbar 521 and two second connectors 522. One end of the second conversion busbar 521 is connected to the first busbar 54 and the third busbar 56 respectively, and the other end is connected to the two second connectors 522 respectively. One of the second connectors 522 is electrically connected to the second shore power access device 6 through a shore power composite cable. This structural arrangement allows power to be transmitted in an orderly manner between the components. By setting up symmetrically distributed first shore power connection boxes and second shore power connection boxes in the first shore power access device and connecting them to each other through busbars, a radial power supply network is formed, thereby improving the reliability and stability of power supply.

[0031] Furthermore, the second shore power access device 6 includes a third shore power connector box 61 and a fourth shore power connector box 62 symmetrically fixedly installed on the port and starboard sides of the electrical distribution room of the second cruise ship 4. The third shore power connector box 61 is provided with a third conversion busbar 611 and two third connectors 612. One end of the third connector 612 is connected to the third conversion busbar 611, and the other end of the third conversion busbar 611 is connected to the fourth shore power connector box 62 and the second distribution panel 63 through the fourth busbar 64 and the fifth busbar 65, respectively. The second distribution panel 63 is connected to the fourth shore power connector box 62 through the sixth busbar 66.

[0032] Furthermore, the fourth shore power connection box 62 is equipped with a fourth conversion busbar 621 and two fourth connectors 622. One end of the fourth conversion busbar 621 is connected to the fourth busbar 64 and the fifth busbar 66 respectively, and the other end is connected to the two fourth connectors 622, ensuring the stability of power distribution inside the second cruise ship 4. By setting symmetrically distributed third and fourth shore power connection boxes in the second shore power access device and interconnecting them through busbars, a radial power supply network is formed, thereby improving the reliability and stability of power supply.

[0033] Furthermore, optical cables are connected between the first conversion busbar 511 and the second conversion busbar 521 and the first distribution panel 53, and between the first distribution panel 53 and the second conversion busbar 521; optical cables are also connected between the third conversion busbar 611 and the fourth conversion busbar 621 and the second distribution panel 63, and between the second distribution panel 63 and the fourth conversion busbar 621. By setting optical cable connections between each conversion busbar and the distribution panel, high-speed and stable transmission of control signals and monitoring data can be achieved, facilitating real-time monitoring and remote management of the shore power system's operating status, thereby improving the system's intelligence level.

[0034] Furthermore, based on the actual berthing status of the first cruise ship 3 and the second cruise ship 4 on the port or starboard side, by operating the switches of the first conversion busbar 511, the second conversion busbar 521, the third conversion busbar 611 and the fourth conversion busbar 621, the corresponding shore power connection path is selected, so that the power and signal of the dock shore power are connected to the cabin power distribution room of the first cruise ship 3 and the second cruise ship 4 along the selected path, thereby providing continuous and stable power support for the cruise ships during berthing.

[0035] Furthermore, the shore power composite cable, as an integrated transmission carrier, possesses the dual function of simultaneously and efficiently transmitting power and signals. It can provide ships docked in port with sufficient high-voltage electrical energy to power various onboard equipment; simultaneously, the cable also integrates dedicated wire pairs or fiber optic components for signal transmission. These components can stably transmit control signals, data signals, etc., enabling tasks such as command interaction between the ship and port control systems, and feedback of equipment status monitoring data, all through these signal channels.

[0036] Specifically, when the first cruise ship 3 and the second cruise ship 4 are docked side by side at the pier, the staff will first determine the connection method of the shore power composite cable based on the docking status of the two cruise ships (port side or starboard side).

[0037] If the first cruise ship 3 and the second cruise ship 4 are docked on the port side, the first shore power cable winch 1 and the second shore power cable winch 2 are connected to the two first connectors 512 in the first shore power connector box 51 on the port side of the first shore power access device 5 on the first cruise ship 3 via shore power composite cables. After the first cruise ship 3 completes the connection, it is connected to the third connector 612 on one side of the second shore power access device 6 on the second cruise ship 4 via shore power composite cables.

[0038] If the first cruise ship 3 and the second cruise ship 4 are docked on the port side, the first shore power cable winch 1 and the second shore power cable winch 2 are connected to the two second connectors 522 in the second shore power connector box 52 on the starboard side of the first shore power access device 5 on the first cruise ship 3 via shore power composite cables. After the first cruise ship 3 completes the connection, it is connected to the fourth connector 622 on one side of the second shore power access device 6 on the second cruise ship 4 via the shore power composite cable.

[0039] After the physical connection of the cables is completed, the appropriate connection path is manually selected by operating the switches of the first conversion busbar 511, the second conversion busbar 521, the third conversion busbar 611 and the third conversion busbar 621. This ensures that the power and signal of the shore power at the dock are accurately and stably connected to the cabin power distribution room of the first cruise ship 3 and the second cruise ship 4 along the selected path, providing continuous and reliable power support for the operation of various equipment such as air conditioning, lighting and communication during the cruise ship docking, and ensuring the smooth operation of the cruise ship.

[0040] This invention establishes a parallel power supply circuit by setting up parallel circuits in the first shore power access device 5 and the second shore power access device 6, and electrically connecting them to the first shore power cable winch 1 and the second shore power cable winch 2 via a shore power composite cable. This forms a parallel power supply circuit, allowing shore power to be directly supplied to both the first cruise ship 3 and the second cruise ship 4, improving the flexibility of power transmission. Furthermore, parallel power supply enables the rational distribution of power load; the two cruise ships can obtain the corresponding power from the parallel circuit according to their real-time power needs, avoiding overload on a single power supply line and extending the service life of cables, connectors, and other equipment. Simultaneously, compared to laying separate shore power lines for each cruise ship, this parallel configuration reduces investment in shore equipment and line laying costs, improves power supply efficiency, and allows both cruise ships to quickly obtain sufficient power after docking, shortening power supply preparation time and improving the operational efficiency of the cruise ships.

[0041] Furthermore, depending on the actual situation of the first cruise ship 3 and the second cruise ship 4 being docked on the port or starboard side, the shore power composite cable can be flexibly connected to the first connector 512, the second connector 522, the third connector 612, or the fourth connector 622. The path is then selected by operating the switches of the first conversion busbar 511, the second conversion busbar 521, and the third conversion busbar 611. The entire process requires no complex equipment debugging or modification; the operation procedure is simple and clear, reducing the excessive demands on the professional skills of the personnel. Even operators with relatively little experience can quickly grasp the key points of operation, significantly improving the operational efficiency of shore power access.

[0042] In terms of adaptability and flexibility, the system features symmetrically installed shore power junction boxes and corresponding connectors designed for different berthing methods of cruise ships (port or starboard berthing). This allows the shore power access system to flexibly adapt to different berthing scenarios without requiring additional modifications to the system or the cruise ship. This high degree of adaptability enables the system to be successfully applied in various inland river terminals with two ships berthing side by side, enhancing its practicality in actual operation.

[0043] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
