[0032] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0033] like Figure 1 As shown, this utility model provides a top-loading battery swapping device for an electric container ship, comprising:

[0034] The enclosure has an open side and is located on the upper side of deck 1, forming a battery compartment inside the enclosure;

[0035] Canopy 2, canopy 2 is set above the enclosure panel;

[0036] Track 3 is fixed inside the enclosure, and the other end of track 3 extends to the outside of the enclosure, forming an extension section;

[0037] The hoisting and traveling mechanism 4 is located above the track 3 and is capable of hoisting and transporting the battery pack 6.

[0038] The battery buffer base 5 is located below the extension section, and the height of the track 3 is less than the top mounting interface 7 of the battery pack 6 located on the battery buffer base 5.

[0039] Specifically, to address the problem in existing technologies where the robotic arm of the shore-based battery swapping vehicle easily interferes with or collides with the battery swapping device on the ship during the top-swap battery pack process, the battery swapping device for electric container ships provided by this utility model features a track 3 with an extension section at the top of the battery compartment. A lifting and traveling mechanism 4 is mounted on the track 3, capable of lifting and transferring the battery pack 6. This enables the lifting of the battery pack 6 from the ship to the battery buffer base 5, and vice versa. The height of the track 3 and the battery buffer base 5 are designed based on the height of the battery pack 6 placed on the battery buffer base 5. The height of the track 3 is set lower than the lifting interface 7 at the top of the battery pack 6 on the battery buffer base 5, ensuring that the lifting interface 7 at the top of the battery pack 6 is higher than the track 3 when it is placed on the battery buffer base. This avoids mechanical interference and collisions between the robotic arm on the shore-based battery swapping vehicle and the track 3 and its supports when the battery pack 6 is lifted, improving the convenience and safety of battery swapping.

[0040] In this embodiment, a track support 8 is provided below the track 3 to support the track 3.

[0041] Optionally, a mounting slot is provided inside the battery compartment. The mounting slot is recessed and installed on the deck 1 of the electric vessel, and a battery mounting base is provided at the bottom of the mounting slot.

[0042] Specifically, the mounting slot is installed in a sunken manner on deck 1 to form a sunken battery compartment. This reduces the height of the battery compartment above deck 1, thereby lowering the center of gravity and improving the stability of the ship.

[0043] In this embodiment, the mounting groove is sunken by 1.2 meters, the bottom of the canopy 2 is 14.6 meters away from the deck, and the width is 4.2 meters. In order to meet the power capacity requirements of the battery compartment, a partition is set in the lower part of the battery compartment. The partition divides the battery compartment into two storage spaces, each of which can hold 3 battery packs 6. The dimensions of the battery pack 6 are 2460×810×2070mm, each pack has 431 kWh of power, weighs 3.8 tons, and the total weight of the 6 battery packs 6 is about 22.8 tons.

[0044] Optionally, the enclosure includes a closed enclosure 9 and a stamped louvered enclosure 10 arranged sequentially from bottom to top.

[0045] Specifically, the design of adding a stamped louvered enclosure 10 to the upper part of the enclosure solves the contradiction between the dual needs of waterproofing and ventilation of the battery compartment in the open environment. The stamped louvered enclosure 10 can meet certain waterproofing requirements, mainly to play a certain role in waterproofing and prevent a large amount of water from accumulating in the battery compartment, and also has the function of forced ventilation.

[0046] In this embodiment, the material of the stamped louvered panel 10 is a stamped louvered plate, the stamping angle of the louvers is 30-45 degrees, and the inclined design enables an airflow of ≥200m under IPX4 waterproof rating. 3 / h can reduce the temperature inside the battery compartment.

[0047] Optionally, a enclosure frame 11 is provided above the enclosed enclosure 9, and a stamped louvered enclosure 10 is disposed within the enclosure frame 11.

[0048] Specifically, the enclosure frame 11 includes a top frame, a bottom frame, and pillars disposed between the two, and a stamped louvered enclosure 10 is installed between the top frame, the bottom frame, and adjacent pillars 14.

[0049] Optionally, multiple fixed guide sleeves 12 are provided on the inner walls of opposite sides of the canopy 2, and stop cylinders 13 are provided on both sides of the hoisting and traveling mechanism 4. The telescopic end of the stop cylinder 13 is provided with a stop post that is inserted and cooperates with the fixed guide sleeve 12.

[0050] Specifically, the fixed guide sleeve 12 is positioned corresponding to the position of each battery mounting base. When the hoisting and traveling mechanism 4 hoists the battery pack 6 above a battery mounting base, the stop cylinder 13 is activated, and its telescopic end drives the stop column to extend and insert into the fixed guide sleeve 12, thereby achieving the positioning of the hoisting and traveling mechanism 4, ensuring the positioning accuracy during the battery swapping process, and improving the accuracy and safety of the battery swapping.

[0051] Optionally, the canopy 2 includes a canopy frame, canopy side panels, and canopy cover. The canopy frame includes multiple pairs of columns 14. The upper ends of each pair of columns 14 are connected by connecting beams to form an inverted U-shape. Adjacent columns 14 are connected by crossbeams. The lower ends of the columns 14 are connected to the surrounding panels.

[0052] Specifically, such as Figure 2 As shown, the lower end of the column 14 is connected to the upper part of the enclosure through the mounting plate to fix the canopy 2. The fixing guide sleeve 12 is fixed inside the crossbeam of the canopy 2, and a pair of positioning guide sleeves are set above each battery mounting seat.

[0053] Optionally, the hoisting traveling mechanism 4 includes:

[0054] The traveling support 15 has a traveling wheel 16 and a power wheel 17 below it. The traveling wheel 16 and the power wheel 17 are located on the upper side of the track 3 and are guided by the track 3.

[0055] The lifting and lowering structure 18 is located in the middle of the traveling support 15;

[0056] The lifting device 19 is connected to the lifting structure 18 and can be lifted and lowered by the lifting structure 18. The grippers of the lifting device 19 cooperate with the lifting interface 7 of the battery pack 6.

[0057] Specifically, such as Figure 3 As shown, the hoisting and traveling mechanism 4 has a rectangular frame at the top, with a support leg connected to each of the four lower corners of the rectangular support. A pair of drive wheels 17 are equipped with drive components, including a motor reducer, which can drive the drive wheels 17 to rotate, enabling the hoisting and traveling mechanism 4 to travel on the track 3. The traveling wheels 16 are rotatably connected to the lower ends of the support legs. The lifting and lowering structure 18 uses a lifting component to drive the lifting device 19 to rise and fall, thereby realizing the lifting and lowering of the battery pack 6. The lifting component can be telescopic or retractable. Without limitation or elaboration, the lifting device 19 adopts a structure that matches the battery pack 6 and its top lifting interface 7. It may include a support plate and openable and closable grippers located on the underside of the support plate. The grippers are arranged in pairs. When the grippers are closed, they can be inserted into the lifting interface 7 to lift the battery pack 6. When the battery pack 6 is placed on the battery mounting base or battery buffer base 5, the grippers can be opened to detach from the battery pack 6. The grippers can be driven by electric cylinders or gripper cylinders, etc., without limitation or elaboration.

[0058] In this embodiment, limiting discs are provided on both sides of the walking wheel 16 and the power wheel 17. The limiting discs are circumferentially protruding and form a guiding cooperation with the track 3 to ensure the stability of walking. A track support 8 is provided below the track 3. The height of the track support 8 is set to 2.1 meters. When the battery pack 6 is placed on the battery buffer base 5, the track 3 is about 0.5m lower than the top of the battery pack 6.

[0059] In this embodiment, the hoisting traveling mechanism 4 also includes a control cabinet 20 located on the lower side of the traveling support 15. The control cabinet 20 controls the operation of the hoisting traveling mechanism 4. The conventional top-mounted battery pack replacement control method can be used, which will not be limited or described in detail here.

[0060] In this embodiment, the stop electric cylinder 13 is arranged on both sides of the rectangular frame, the stroke of the stop electric cylinder 13 is 150mm, and the insertion depth of the stop post is not less than 80mm.

[0061] Optionally, battery pack 6 is a container battery.

[0062] In this embodiment, the electric container ship has six container batteries, which are not afraid of wind and rain and have strong environmental adaptability.

[0063] Optionally, there are two battery cache bases 5.

[0064] Specifically, two battery buffer bases 5 are installed on the enclosure side, which can improve battery swapping efficiency.

[0065] In this embodiment, the battery swapping process involves the battery swapping vehicle carrying a fully charged battery pack 6 to the battery swapping location on the shore. The hoisting and traveling mechanism 4 on the ship lifts the undercharged battery pack 6 from the battery compartment onto a battery buffer base 5. The robotic arm on the battery swapping vehicle then places a fully charged battery pack 6 onto another battery buffer base 5. The hoisting and traveling mechanism 4 then lifts the fully charged battery pack 6 to the battery mounting seat. The robotic arm then lifts the undercharged battery pack 6 onto the battery swapping vehicle. This process is repeated 6 times to complete the battery swapping, reducing the overall battery swapping time to less than 45 minutes.

[0066] This utility model also provides a top-mounted battery swapping system for electric container ships, comprising:

[0067] The aforementioned top-mounted battery pack swapping device for electric container ships;

[0068] The battery swapping vehicle is located on the shore and is equipped with multiple battery pack carrying spaces and a battery swapping robotic arm.

[0069] Specifically, the battery swapping system uses a top-swap battery pack method for swapping batteries on electric container ships. This method avoids mechanical interference and collisions between the robotic arm on the shore-based battery swapping vehicle and the track 3 and its support structure when the robotic arm lifts the battery pack 6, thus improving the convenience and safety of battery swapping.

[0070] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
