Description

Technical Field

[0001] This utility model relates to the field of ship battery swapping technology, and more specifically, it relates to a ship battery replacement hoisting structure in a ship battery separation mode. Background Technology

[0002] As a key component in the promotion of new energy ships, ship battery swapping technology faces severe challenges from surface wave interference in practical applications. Waves cause ships to undergo complex six-degree-of-freedom motion, and this continuous swaying greatly complicates battery swapping operations.

[0003] The impact of waves on battery swapping operations is mainly reflected in the dynamic docking process. When the vessel rolls and sways with the waves, irregular relative displacement occurs between the battery compartment and the battery swapping platform, making it difficult to maintain stable alignment of their mechanical interfaces. This dynamic misalignment not only prevents the spreader from accurately grabbing the battery but also easily leads to mechanical collisions during docking, potentially damaging the battery or connectors. Especially in open waters or rough sea conditions, the randomness and unpredictability of waves further increase the risks of battery swapping operations.

[0004] Therefore, a ship battery replacement hoisting structure under the ship-battery separation mode is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ship battery replacement hoisting structure in the ship battery separation mode that avoids the influence of water surface fluctuations and improves the success rate of ship battery swapping.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A ship battery replacement hoisting structure in a ship-battery separation mode includes a support truss with a mooring area on one side. Two sets of top-mounting positioning components are provided at the bottom of the support truss. Each top-mounting positioning component has a hollow threaded drive block with a shaft. The shaft of the hollow threaded drive block faces the mooring area. A servo motor is installed on one side of the hollow threaded drive block, and a top rod is slidably connected to the shaft of the hollow threaded drive block.

[0007] The present invention is further configured such that: a fork is installed on one side of the top of the supporting truss, the fork has a movable end, a rope winding device is provided at the top of the movable end of the fork, and a lifting device is provided below the rope winding device.

[0008] The present invention is further configured such that: the rope winding device has a rope fixing component and a rope winding component; the lifting device has multiple sets of wire ropes; one end of the wire rope is fixedly connected to the rope fixing component; and the other end of the wire rope is fixedly connected to the rope winding component.

[0009] The present invention is further configured such that: the top boat positioning component also has a mounting block, the mounting block is fixedly connected to the support truss, a lead screw is provided on the side of the mounting block away from the support truss, and a motor is installed at one end of the lead screw.

[0010] The present invention is further configured such that: a slider is slidably connected to the side of the lead screw away from the supporting truss, a fixed block is provided on the side of the slider away from the supporting truss, and the hollow threaded drive block and servo motor are installed above the fixed block.

[0011] Another embodiment of this utility model is configured such that a positioning block is provided on the side of the top rod near the mooring area.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. When the vessel enters the mooring area, the crew attaches the mooring line to the mooring bollard on the shore. The servo motor, drive block, and push rod are used to hold the vessel in place until the mooring line on the vessel is taut. The support truss keeps the mooring line parallel to the push rod, which can keep the distance between the vessel and the support truss unaffected by water surface fluctuations and improve the success rate of the vessel's battery swapping.

[0013] 2. By using a servo motor, drive block, and push rod to hold the vessel in place, the distance between the vessel and the support truss can be measured using the encoder inside the servo motor. This provides a reference for the movement distance of the forks during subsequent battery swapping, thus improving battery swapping accuracy. Attached Figure Description

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Example 1, please refer to Figure 1-4 The present invention provides the following technical solution: Specifically, this refers to a ship battery replacement hoisting structure under a ship-battery separation mode, see [reference]. Figure 1-3 The system includes a support truss 1, with a mooring area on one side and multiple charging positions on the other side, some of which have battery packs. The support truss 1 is also equipped with a distance measuring device to measure the distance between the battery packs on the vessel and the support truss 1, as well as the positional deviation in the vessel's direction of travel. A fork 2 is mounted on one side of the top of the support truss 1. The fork 2 has a moving end, and a rope winding device 3 is located at the top of the moving end. A lifting device 4 is located below the rope winding device 3, and the lifting device 4 has multiple sets of jaws. Opening the jaws prepares for lifting the battery packs, and retracting the jaws prepares for unloaded movement. The rope winding device 3 has a rope securing assembly and a rope winding assembly. The lifting device 4 has multiple sets of... A steel wire rope is used, with one end fixedly connected to a rope fixing assembly and the other end fixedly connected to a rope take-up assembly. The battery pack is grabbed by the lifting device 4, and the rope take-up device 3 is driven to lift the battery pack. The forks 2 move away from the ship. After the support truss 1 moves to an empty charging position, the forks 2, rope take-up device 3, and lifting device 4 are driven to lower the battery pack into the charging position. Then, the support truss 1 moves to the charging position of the fully charged battery pack, and the forks 2, rope take-up device 3, and lifting device 4 are driven to lift the fully charged battery pack and place it on the ship. The bottom of the support truss 1 is equipped with two sets of ship-mounting positioning components 5. The ship-mounting positioning components 5 are used to hold the ship in place and cooperate with the ship's mooring lines to prevent the ship from swaying and avoid battery swapping failure.

[0022] See Figure 4 The top-mounted positioning component 5 has a mounting block, which is fixedly connected to the support truss 1. A lead screw 51 is provided on the side of the mounting block away from the support truss 1. A motor is installed at one end of the lead screw 51. A slider 52 is slidably connected to the side of the lead screw 51 away from the support truss 1. A fixing block 53 is provided on the side of the slider 52 away from the support truss 1. A hollow threaded drive block 54 is installed above the fixing block 53. The hollow threaded drive block 54 has a shaft, which faces the mooring area. A servo motor 55 is installed on one side of the hollow threaded drive block 54. A top rod 56 is slidably connected to the shaft of the hollow threaded drive block 54.

[0023] When the vessel enters the mooring area, the crew secures the mooring line to the bollard on the shore. At this time, the servo motor 55 is driven, causing the hollow threaded drive block 54 to rotate. This drives the push rod 56 to slide closer to the vessel, pressing against it until the mooring line is taut. During this process, the support truss 1 is moved so that the mooring line is parallel to the push rod 56. This keeps the distance between the vessel and the support truss 1 unaffected by water surface fluctuations, improving the success rate of the vessel's battery swapping. Furthermore, by having the push rod 56 press against the vessel, the encoder inside the servo motor 55 can help measure the distance between the vessel and the support truss 1. This provides a reference for the movement distance of the forks 2 during subsequent battery swapping, improving the accuracy of the battery swapping process.

[0024] When the ship is changing its battery, the motor on the lead screw 51 releases the internal brake. At this time, if the water surface fluctuates and the ship moves up and down, the push rod 56 moves up and down with the ship to prevent the push rod 56 from breaking due to its inability to move up and down.

[0025] Example 2 differs from Example 1 only in that a positioning block is provided on the side of the top rod 56 near the mooring area, and a positioning groove is provided at the corresponding position on the vessel.

[0026] When a vessel enters the mooring area, a positioning block is inserted into the vessel's positioning slot, ensuring that the battery packs of vessels requiring battery swapping are in essentially the same position when entering the mooring area for swapping. This allows for battery swapping to be performed based solely on the distance between the battery packs on the vessel and the supporting truss 1, thereby improving swapping efficiency.

[0027] The working principle of the ship battery replacement hoisting structure in the ship battery separation mode provided in Embodiment 1 of this utility model is as follows: After the crew moors the vessel into the mooring area, they attach the mooring line to the mooring bollard on the shore. The distance measuring device on the support truss 1 measures the distance and drives the support truss 1 to the corresponding position on the vessel. This drives the servo motor 55, causing the hollow threaded drive block 54 to rotate, which in turn drives the push rod 56 to slide closer to the vessel. The push rod 56 presses against the vessel until the mooring line on the vessel is taut. The data from the encoder inside the servo motor 55 is used to calculate the distance between the battery pack on the vessel and the support truss 1. This distance is then measured again by the distance measuring device, and the measured data is compared with the data calculated by the encoder to accurately determine the battery pack position. Finally, the forks 2 are driven to move above the battery pack on the vessel, and the rope winding device 3 drives the lifting device 4 to move downwards and lower the battery pack. Above the battery pack, the grippers of the spreader 4 open to prepare for lifting the battery pack. The rope winding device 3 is driven to move in the opposite direction to lift the battery pack. During this process, even if there are waves on the water surface, the boat is blocked by the top rod 56 and cannot move towards or away from the support truss 1, nor can it move forward or backward in the direction of travel. It can only move up and down because the servo motor 55 brake is released. When moving up and down, the rope winding device 3 lifts slowly at the beginning of the lifting until the battery pack reaches a suitable height. Then, it accelerates the lifting until the height reaches the height to be separated from the boat. Then, the forks 2 are driven to move the battery pack to the charging position to achieve separation of the boat and the battery. After that, the battery pack is placed in an empty charging position, and then the fully charged battery pack is lifted from the charging position and placed in the corresponding position on the boat to complete the battery swap.

[0028] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
