Technical Field
[0001] This utility model relates to the field of charging facility technology, specifically to a ship shore-based charging and lifting device. Background Technology
[0002] With the rapid development of new energy technologies, electric ships, thanks to their environmental advantages, have been gradually promoted in various fields such as inland waterway transportation, marine engineering support, and passenger transport. However, due to limitations in the energy efficiency of current battery technology and the coverage of charging infrastructure, pure electric ships generally face the challenge of insufficient driving range, especially during long-distance voyages where frequent refueling is required. Furthermore, the inadequate layout of charging facilities along inland waterways further restricts the operational flexibility and service range of ships.
[0003] Inland waterways often traverse mountainous or complex terrain areas, with sparsely distributed wharves along the banks and long distances between them. In addition, the rugged terrain on both sides of the waterways makes it difficult to select charging station sites and lay power transmission lines. Traditional shore-based charging facilities are unable to meet the dynamic energy replenishment needs of ships, becoming a key bottleneck restricting the large-scale application of electric ships.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0032] For information on ship-based shore-based charging and lifting devices, please refer to the appendix. Figures 1-3 One possible implementation is as follows: Includes lifting power source 1, cable reel 3, lifting guide rail 4, and lifting platform 5; The lifting guide rail 4 is fixed to the bank wall, and the lifting platform 5 is slidably connected to the lifting guide rail 4. The lifting power source 1 and the cable reel 3 are located at the top of the bank wall. The lifting power source 1 is connected to the lifting platform 5 through the first cable 2 and controls its lifting height. The cable reel 3 is driven by the power source and can release or wind cables according to the height changes of the lifting platform 5. Specifically, this can be achieved by adjusting the speed ratio between the cable reel 3 and the lifting power source 1. The lifting speed of the lifting platform 5 is controllable, and the rotation speed of the cable reel 3 is also controllable. As long as the linear speeds of the lifting power source 1 and the cable reel 3 are approximately the same, the release or winding speed of the cable reel 3 will be consistent with the lifting speed of the lifting platform 5.
[0033] In the above embodiments, this device can be applied to both ordinary high-bank ports (where the bank is higher than the sea surface) and non-port areas within waterways. In non-port areas, such as when the waterway passes through mountainous areas with cliffs on both sides, a power distribution room (powered by nearby wind power) can be installed at the top of the cliffs. The power distribution room is equipped with a lifting power source 1 and a cable reel 3. A lifting guide rail 4 is installed between the power distribution room and the water surface. Depending on the bank conditions, the lifting guide rail 4 can be directly fixed to the bank, or the bank can be leveled and reinforced before fixing the lifting guide rail 4, and then the lifting platform 5 can be slidably mounted on the lifting guide rail 4, moving up and down between the power distribution room at the top of the bank and the water surface at the bottom of the bank. The installation method is similar for ports.
[0034] The lifting platform 5 is equipped with charging equipment. When not in charging operation, the lifting platform 5 moves to the top, which is the location of the power distribution room. When a ship needs charging, the lifting platform 5, carrying the charging equipment, moves down to the ship's height. The charging equipment provides a standard interface for ship charging, allowing the ship to connect and charge. After charging is complete, the interface is disconnected, and the charging equipment moves back to the top.
[0035] In the above embodiments, the lifting power source 1 provides power for the movement of the lifting platform 5. Connected to the lifting platform 5 via the first cable 2, its lifting height can be controlled to meet the charging needs of different ships or water levels. The cable reel 3, driven by the power source, can adaptively release or reel cables according to changes in the height of the lifting platform 5 to power the charging equipment, preventing excessive tension or slack in the cables and ensuring a stable and safe charging process. The lifting guide rail 4 is fixed to the shore wall, providing a stable sliding track for the lifting platform 5. Whether in high-shore ports or non-port areas within waterways, such as cliffs, it ensures smooth lifting and lowering of the platform. The lifting platform 5 is slidably connected to the lifting guide rail 4, allowing it to flexibly move with the charging equipment to the height of the ship, accommodating ships of different sizes and water levels, improving equipment efficiency and safety, and providing an efficient, stable, and flexible solution for shore-based ship charging.
[0036] In one possible implementation, see Appendix Figure 1 and Figure 2 The lifting guide rail 4 includes two parallel steel rails 41, each with a concave cavity structure 411 on one side. The lifting platform 5 is limited and slidably disposed within the concave cavity structure 411 on both sides. Located in the lower end region of the steel rails 41, a limiting member 412 is installed within the concave cavity structure 411 of the two steel rails 41 to restrict the further sliding of the lifting platform 5. This limiting member 412 can be a section of horizontal steel welded to the concave cavity structure 411 on both sides of the steel rails 41. The limitation and slidability of the lifting platform 5 within the concave cavity structure 411 on both sides further enhances the connection stability, prevents the lifting platform 5 from derailing, and improves safety. The limiting member 412 installed within the concave cavity structure 411 in the lower end region of the steel rails 41 effectively restricts the lifting platform 5 from continuing to slide down, preventing it from derailing and causing an accident. This provides a reliable guarantee for the safe operation of the entire device and ensures a stable and orderly shore-based charging process for the ship.
[0037] In one possible implementation, see Appendix Figure 4 and Figure 5 A suspension 6 is installed at the top of the bank, with one end fixed to the bank foundation (this end is also held down by a cable reel 3) and the other end extending out of the bank. A first pulley 61 is installed at the outer end of the suspension 6. A second pulley 51 and a third pulley 52 are installed on the lifting platform 5. A first cable 2, after being led out from the lifting power source 1, passes sequentially through the first pulley 61, the second pulley 51, and the third pulley 52 before its end connects to the suspension 6. For the lifting power principle described in the above embodiment, please refer to [reference needed]. Figure 6The second pulley 51 and the third pulley 52 of the lifting platform 5 form a movable pulley. The first pulley 61 provides a stable turning support point for the first cable 2, ensuring the stability of the cable's running path. The first pulley 61 cooperates with the second pulley 51 and the third pulley 52 on the lifting platform 5, and the first cable 2 passes through them in sequence, changing the direction of force transmission. Among them, the second pulley 51 and the third pulley 52 form a movable pulley structure. According to the principle of labor saving of movable pulleys, it can reduce the pulling force required by the lifting power source 1, reduce the power burden, and make the lifting operation of the lifting platform 5 easier, more efficient, and smoother, improving the economy and reliability of the entire device operation.
[0038] In one possible implementation, see Appendix Figure 4 The upper end of the rail 41 is connected to the shoreline via a second cable 42; and / or, the middle part of the rail 41 is connected to the original shoreline or artificial structure via a connector 43. In the above embodiments, the connection of the upper end of the rail 41 to the shoreline via the second cable 42 effectively disperses the force borne by the fixed structure of the rail 41, enhances the stability of the rail 41, and prevents it from loosening or deforming due to long-term stress or external impact. At the same time, the connection of the middle part of the rail 41 to the original shoreline or artificial structure via the connector 43 further strengthens the overall structure of the rail 41, improves the bending and torsional resistance of the rail 41 in the horizontal and vertical directions, ensures that the rail 41 remains stable during the frequent lifting and lowering of the lifting platform 5, provides reliable support for the lifting platform 5, and ensures the safe and stable operation of the entire device.
[0039] In one possible implementation, see Appendix Figure 9 and Figure 10The cable reel 3 includes a core 31, divider discs 32, a winding motor 33, and a junction box 34. The core 31 is driven by the winding motor 33. The divider discs 32 are fixed at intervals around the outer periphery of the core 31. A cable receiving area 35 is formed between two adjacent divider discs 32. One end of the junction box 34 is rotatably fitted inside the core 31 and connected to the cable, while the other end is supported by the frame of the cable reel 3. The cable end within the divider 32 is provided with a first conductive ring, and the corresponding cable end within the junction box 34 is provided with a second conductive ring. The first conductive ring is located on the inner ring surface of the winding core 31, and the second conductive ring is located on the inner and outer ring surfaces of the junction box 34. The first and second conductive rings can rotate relative to each other and conduct electricity. It should be noted that in the above embodiment, the winding motor 33 only drives the cable reel 3 to rotate during the lifting process of the lifting platform 5 (the junction box 34 remains stationary), and the first and second conductive rings will only rotate relative to each other. Once the lifting is complete, the lifting platform 5 stops lifting, the winding motor 33 stops rotating, and the first and second conductive rings can then conduct electricity to each other, avoiding conduction while rotating. In a possible alternative, the first and second conductive rings are replaced with relative but non-contact electromagnetic induction coils, which transmit electrical energy in a contactless manner, similar to the principle of a transformer.
[0040] In one possible implementation, see Appendix Figure 5 and Figure 7 The suspension 6 has a cable frame 7 at its end. The cable frame 7 includes side plates 71 and support shafts 72. At least two side plates 71 are arranged opposite each other, and the two ends of at least two support shafts 72 are rotatably connected to the respective side plates 71. The cable frame 7 is rotatably connected to the suspension 6, and its rotation angle is adjustable. An adjusting rod 73 is fixedly connected to the cable frame 7. The two ends of the adjusting rod 73 are rotatably connected to the suspension 6. At least one end of the adjusting rod 73 is provided with a turbine, and the suspension 6 is provided with a worm gear 62 for driving the turbine. In the above embodiment, the side plates 71 and support shafts 72 of the cable frame 7 form a structure that provides an orderly placement space for cables, prevents cables from becoming tangled, and ensures smooth cable winding and unwinding. The cable frame 7 is rotatably connected and its angle is adjustable, allowing the cable frame angle to be adjusted as needed. The rotatable connection between the adjusting rod 73 and the suspension 6, combined with the turbine worm gear 62 structure, allows for adjustment of the rotation angle of the cable frame 7, which is easy to operate and can self-lock to maintain the angle. This design makes cable management more efficient, reduces cable wear, improves the reliability and stability of the device, and provides strong support for shore-based charging operations for ships.
[0041] In one possible implementation, the lifting guide rail 4 is perpendicular to the water surface, or angled towards the water surface.
[0042] In some man-made port areas, the shoreline is planned and constructed to present a regular, upright shape. For this type of shoreline, installing the lifting guide rail 4 perpendicular to the water surface is an extremely suitable choice. The vertically installed lifting guide rail 4 can perfectly fit the upright shoreline, making full use of the vertical space. During installation, simply securing the guide rail firmly to the upright shoreline ensures its stability. When a ship is docked at the shore and needs charging, the vertically installed lifting guide rail 4 allows the lifting platform 5 to rise and fall vertically in a straight line.
[0043] Along the banks of many naturally formed rivers and lakes, the shoreline often exhibits a natural sloping shape. This sloping shoreline is formed over a long period by natural factors such as water erosion and geological movements, resulting in varying slopes and potentially uneven surfaces. For such naturally sloping shorelines, installing the lifting guide rail 4 at an angle towards the water surface is a more reasonable solution. The angled installation can be adjusted according to the actual slope of the shoreline, allowing for a better fit between the guide rail and the shoreline. When a vessel approaches the sloping shoreline, the angled lifting guide rail 4 allows the lifting platform 5 to rise and fall along the slope. This movement method better matches the trajectory of the vessel approaching the shore, facilitating docking between the vessel and the charging equipment. This approach adapts to the characteristics of natural sloping terrain, enabling the construction of charging facilities in non-port areas, providing convenient charging services for passing vessels, and solving the problem of difficult vessel charging in these areas.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
