Description

Technical Field

[0001] This utility model relates to the field of battery swapping system technology, and in particular to a ship battery swapping station. Background Technology

[0002] Most ships are powered by fuel, leading to water and air pollution. Therefore, electric-powered new energy ships have begun to appear on the market. While these offer better environmental benefits, they face significant challenges in terms of range. Ship transport often involves long journeys, making it extremely inconvenient to carry spare batteries, as they would occupy considerable space and increase the ship's weight. Therefore, battery swapping stations are needed at docks to facilitate battery swapping for docked ships.

[0003] Currently, the battery boxes used to power ships are usually containerized power battery units. Battery swapping for ships typically involves building charging and swapping stations not far from the port, using short-distance vehicle delivery, then hoisting the containerized power battery units and installing them on the ship. This battery swapping process is cumbersome. Furthermore, as ships increase in size, the battery boxes also need to be larger to ensure sufficient sailing distance, making transportation difficult and requiring a large overall footprint. In addition, using crane-type battery swapping devices poses a risk of crane tilting or collapsing during the swapping process, creating certain safety hazards.

[0004] Therefore, there is a need for a ship-based battery swapping station that uses a traveling structure instead of a conventional boom structure to improve the stability and safety of battery swapping, as well as to improve battery swapping efficiency and accuracy, while also reducing the overall footprint.

The first limiting part has a first position and a second position, and the battery box is provided with a second limiting part that cooperates with the first limiting part.

[0010] The first limiting part is located at the first position, and the first limiting part is engaged with the second limiting part;

[0011] The first limiting part is located in the second position, and the first limiting part is separated from the second limiting part.

[0012] As a further improvement of this utility model, the first limiting part includes a limiting rod disposed at the driving end of the driving component and a first limiting block disposed at the end of the limiting rod away from the driving component; the second limiting part includes a second limiting block disposed on the battery box, the second limiting block having a hollow cavity inside, and a limiting hole communicating with the hollow cavity at the top of the second limiting block; the first limiting block is inserted into the hollow cavity from the limiting hole at the second position and can rotate within the hollow cavity, thereby enabling the first limiting block to switch between the first position and the second position.

[0013] As a further improvement of this utility model, the driving assembly includes a turntable and a driving rod disposed on the main body. The turntable is horizontally disposed, and its bottom end is connected to the first limiting part. A guide groove is provided on the circumferential surface of the turntable. The driving rod is vertically disposed, and a driving part extending outward in the radial direction is provided on the circumferential surface of the driving rod. The driving part is inserted into the guide groove. The guide groove includes four driving guide grooves and a restoration guide groove connected end to end. The driving guide groove is inclined upward. The restoration guide groove includes a vertically disposed vertical part and an inclined part inclined downward. The top of the driving guide groove is connected to the top of the vertical part, the bottom of the vertical part is connected to the top of the inclined part, the bottom of the inclined part is connected to the bottom of the next driving guide groove, and the bottommost end of the inclined part is inserted into the driving guide groove.

[0014] As a further improvement of this utility model, at least one positioning mechanism is provided on both sides of the ship berthing position, and the positioning mechanisms on both sides clamp and fix the ship.

[0015] As a further improvement of this utility model, the positioning mechanism includes a push rod disposed on the foundation, a positioning motor for driving the push rod to move, and a push plate disposed on the push rod.

[0019] According to the above-described solution, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses a battery swapping robot to transport the battery box between the ship's docking position and the battery compartment, eliminating the need for vehicles to deliver the battery box. This effectively reduces the battery swapping transfer process, simplifies the entire battery swapping process, avoids the phenomenon of battery boxes falling or being damaged due to the cumbersome battery swapping transfer process, and improves the overall working stability and safety.

Detailed Implementation

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] See Figure 1-6This utility model provides a ship battery swapping station, including a foundation 11 and a support frame 12 mounted on the foundation 11. The foundation 11 has at least one ship berthing position 2 and at least one battery compartment 4 for storing battery boxes 81. At least one battery swapping robot 3 is mounted on the support frame 12. A first displacement mechanism 5 is provided between the battery swapping robot 3 and the support frame 12. The battery swapping robot 3 moves to a suitable power-taking position and a battery-swapping position via the first displacement mechanism 5. The battery swapping robot 3 includes a movable frame 31 driven by the first displacement mechanism 5 and a second position mounted on the movable frame 31. The system comprises a moving mechanism 6, a lifting mechanism driven by the second moving mechanism 6, and a lifting device 33 driven by the lifting mechanism. Preferably, there are two support frames 12, which are respectively set on both sides of the battery compartment 4 and the ship docking position 2. The two ends of the battery swapping robot 3 are respectively set on the two support frames 12, that is, the support frames 12 and the battery swapping robot 3 form a gantry structure. The moving frame 31 spans across the battery compartment 4 and the ship docking position 2. The first moving mechanism 5 and the second moving mechanism 6 adjust the horizontal position of the lifting device 33 and the battery box 81, and the lifting mechanism adjusts the horizontal position of the lifting device 33. With the battery box 81 in a vertical position, the lifting device 33 moves between the ship's berth 2 and the battery compartment 4, transporting the depleted battery box 81 from the ship to the battery compartment 4, and then transporting the fully charged battery box 81 from the battery compartment 4 back to the ship, completing the battery swap. This utility model uses the battery swapping robot 3 to transport the battery box 81 between the ship's berth 2 and the battery compartment 4, eliminating the need for vehicles to deliver the battery box 81. This effectively reduces the battery swapping transfer process, simplifies the entire battery swapping procedure, and avoids the phenomenon of the battery box 81 falling or being damaged due to the cumbersome battery swapping transfer process. To improve overall operational stability and safety, a gantry-structured battery swapping robot 3 replaces the conventional boom structure, allowing it to span above the battery compartment 4 and the ship berthing position 2 to transport the battery boxes 81. This not only improves the stability and safety of the battery swapping process but also effectively reduces the footprint of the battery swapping robot 3. Furthermore, the battery swapping robot 3, through multi-axis linkage, can adjust the position of the battery boxes 81 in multiple directions, enabling precise installation on the ship or placement within the battery compartment 4, effectively improving battery swapping accuracy and achieving flexible intelligent battery swapping, thereby increasing battery swapping efficiency.

[0037] As one embodiment of this utility model, two battery swapping robots 3 are provided, with different heights. One battery swapping robot 3 is in use, and the other is in standby mode. When the battery swapping robot 3 in use malfunctions and needs repair, the staff can use the standby battery swapping robot 3 to perform the work. The redundant design of two battery swapping robots 3 can avoid the battery swapping operation from stopping due to the failure of the battery swapping robot 3, and can ensure the continuity and stability of the battery swapping operation. In addition, two battery swapping robots 3 can also be used to work together. For example, one battery swapping robot 3 goes to the ship to retrieve the depleted battery box 81 and carries the depleted battery box 81 to the battery compartment 4 for charging, while the other battery swapping robot 3 goes to the battery compartment 4 to retrieve the fully charged battery box 81 and carries the fully charged battery box 81 to the ship. The simultaneous operation of two battery swapping robots 3 can reduce the operation time by nearly half compared to the operation of one battery swapping robot 3, which can effectively improve work efficiency.

[0038] As an embodiment of the present utility model, the lifting device 33 includes a body 331 connected to the lifting mechanism, a drive assembly disposed on the body 331, and a first limiting part driven by the drive assembly. The first limiting part has a first position and a second position, and the battery box 81 is provided with a second limiting part that cooperates with the first limiting part.

[0039] The first limiting part is located in the first position, and the first limiting part is engaged with the second limiting part;

[0040] The first limiting part is located in the second position, and the first limiting part is separated from the second limiting part.

[0041] During operation, the first limiting part is initially located in the second position. When the first limiting part moves to the appropriate working position, the drive component drives the first limiting part to switch from the second position to the first position. The first limiting part and the second limiting part engage, completing the fixed connection between the lifting device 33 and the battery box 81. When the lifting device 33 carries the battery box 81 to the designated position, the drive component drives the first limiting part to switch from the first position to the second position. The first limiting part and the second limiting part separate, thus separating the lifting device 33 from the battery box 81 and completing the transportation of the battery box 81.

[0042] As an embodiment of this utility model, the first limiting part includes a limiting rod 332 disposed at the driving end of the driving component and a first limiting block 333 disposed at the end of the limiting rod 332 away from the driving component; the second limiting part includes a second limiting block 811 disposed on the battery box 81, the second limiting block 811 having a hollow cavity inside, and a limiting hole 812 communicating with the hollow cavity at the top of the second limiting block 811; the first limiting block 333 is inserted into the hollow cavity from the limiting hole 812 in a second position and can rotate in the hollow cavity, realizing the switching of the first limiting block 333 between a first position and a second position, that is, when the first limiting block 333 is in the second position, it can pass through the limiting hole 812, and the lifting device 33 and the battery box 81 can be separated, while when the first limiting block 333 is in the first position, it cannot pass through the limiting hole 812, thus realizing the fixed connection between the lifting device 33 and the battery box 81.

[0043] In one embodiment of this utility model, the driving assembly includes a turntable 334 and a driving rod 335 mounted on the body 331. The turntable 334 is horizontally positioned, and its bottom end is connected to a first limiting part. A guide groove is provided on the circumferential surface of the turntable 334. The driving rod 335 is vertically positioned, and a driving part 3351 extending outward in the radial direction is provided on the circumferential surface of the driving rod 335. The driving part 3351 is inserted into the guide groove, and the turntable 334 is driven to rotate by the vertical movement of the driving rod 335. The guide groove includes four drive guide grooves 3341 connected end to end and a restoration guide groove. One drive guide groove 3341 and one restoration guide groove constitute a set. The turntable 334 occupies 1 / 4 of the circumference. After the drive unit 3351 passes through a drive guide groove 3341 and a restoration guide groove, the turntable 334 rotates 90°, realizing the switching of the first limit block 333 between the first position and the second position. The drive guide groove 3341 is inclined upward, and the restoration guide groove includes a vertically arranged vertical part 3342 and an inclined part 3343 inclined downward. The top of the drive guide groove 3341 is connected to the top of the vertical part 3342, the bottom of the vertical part 3342 is connected to the top of the inclined part 3343, and the bottom of the inclined part 3343 is connected to the bottom of the next drive guide groove 3341.

[0044] Working process: The first limiting block 333 is initially in the second position, and the drive rod 335 is initially located at the bottom of the drive guide groove 3341. The first limiting block 333 first enters the hollow cavity through the limiting hole 812. After the lifting device 33 contacts the battery box 81, as the lifting device 33 descends, the upper surface of the battery box 81 applies an upward thrust to the bottom of the drive rod 335, causing the drive rod 335 to move upward. The drive unit 3351 moves along the drive guide groove 3341 and drives the turntable 334 to rotate. The first limiting block 333 switches from the second position to the first position. At this time, the first... The limiting block 333 cannot pass through the limiting hole 812, thus completing the fixed connection between the lifting device 33 and the battery box 81. Subsequently, the lifting mechanism slowly lifts the lifting device 33, and the battery box 81 separates from the drive rod 335. The thrust exerted by the battery box 81 on the bottom of the drive rod 335 is eliminated, and the drive rod 335 moves downward under its own weight. The drive part 3351 moves along the recovery guide groove and falls to the bottom of the inclined part 3343, which is the bottom of the next drive guide groove 3341, in preparation for the next position switch. At the same time, the battery swapping robot 3 transports the battery box 81.

[0045] Once the lifting device 33 and battery box 81 reach the designated position above, the lifting mechanism slowly lowers them. As the lifting device 33 descends, the upper surface of the battery box 81 applies an upward thrust to the bottom of the drive rod 335, causing the drive rod 335 to move upward. The drive unit 3351 moves along the drive guide groove 3341 and drives the turntable 334 to rotate. The first limiting block 333 switches from the first position to the second position. At this time, the first limiting block 333 can pass through the limiting hole 812. Subsequently, the lifting mechanism lifts the lifting device 33. The limiting block 333 separates the lifting device 33 from the battery box 81 through the limiting hole 812. As the lifting device 33 rises, the battery box 81 separates from the drive rod 335. The thrust exerted by the battery box 81 on the bottom of the drive rod 335 is eliminated. The drive rod 335 moves downward under its own weight. The drive part 3351 moves along the recovery guide groove and falls to the bottom of the inclined part 3343, that is, the bottom of the next drive guide groove 3341, in preparation for the next position switch. At this time, the battery swapping robot 3 completes the transportation of the battery box 81.

[0046] This invention uses a turntable 334 and a drive rod 335 instead of a conventional motor to switch the position of the first limiting part. After the lifting device 33 contacts the battery box 81, the first limiting part can automatically switch from the second position to the first position, so that the lifting device 33 and the battery box 81 are fixedly connected. When the lifting device 33 moves the battery box 81 to the designated position, the first limiting part can automatically switch from the first position to the second position, so that the lifting device 33 and the battery box 81 are separated, realizing the automatic switching of the position of the first limiting part, improving work stability and work efficiency.

[0047] In one embodiment of this utility model, the bottom end of the inclined portion 3343 is inserted into the drive guide groove 3341. That is, when the drive portion 3351 falls to the bottom end of the inclined portion 3343, it is in the drive guide groove 3341 and no longer corresponds to the vertical portion 3342. Therefore, when the drive portion 3351 is subjected to an upward thrust, the drive portion 3351 moves upward and contacts the top guide surface of the drive guide groove 3341. Then, under the guidance of the guide surface, it moves upward along the drive guide groove 3341, avoiding the drive portion 3351 from moving upward along the vertical portion 3342, thereby further improving the overall working stability and reliability.

[0048] As an embodiment of this utility model, the lifting device 33 is equipped with a camera, which can capture real-time images of the area below the lifting device 33. When the lifting device 33 is lifting or lowering the battery box 81, the camera can accurately position the lifting device 33 based on the real-time images captured, thereby enabling the lifting device 33 to accurately place the battery box 81 in the designated position and further improve the battery swapping accuracy.

[0049] As one embodiment of this utility model, a rotating disk and a rotary motor driving the rotating disk are provided between the lifting device 33 and the lifting mechanism. The lifting device 33 rotates with the rotating disk. When the lifting device 33 is lifting or lowering the battery box 81, the lifting device 33 can be rotated through the rotating disk to adjust the angle of the lifting device 33. That is, the angle of the lifting device 33 can be adjusted according to the specific mooring angle of the ship, so that the angle between the lifting device 33 and the battery box 81 is the same, or the angle between the battery box 81 and the placement position is the same. This can improve the overall applicability and improve the battery swapping accuracy.

[0050] See Figure 7 As an embodiment of this utility model, at least one positioning mechanism is provided on both sides of the ship berthing position 2. The positioning mechanisms on both sides clamp and fix the ship. By positioning the ship through the positioning mechanism, it can not only ensure that the ship is accurately berthed on the ship berthing position 2, but also keep the ship stationary during the battery swapping process, avoid the ship from swaying, and effectively improve the battery swapping accuracy.

[0051] As an embodiment of this utility model, the positioning mechanism includes a push rod 21 mounted on the foundation 11, a positioning motor that drives the push rod 21 to move, and a push plate 22 mounted on the push rod 21. The first end of the push rod 21 is connected to the positioning motor, and the second end of the push rod 21 is connected to the push plate 22. When the ship enters the ship berthing position 2, the positioning motor drives the push rod 21 and the push plate 22 to move in the direction of the ship. The push plates 22 on both sides clamp the ship in the middle, completing the positioning of the ship. The push plates 22 on both sides apply a thrust to the ship to limit the ship's left and right swaying, and apply a frictional force to the ship to limit the ship's forward and backward swaying. Preferably, the push plate 22 is provided with a limiting block, and the ship is provided with a limiting groove. The limiting block is inserted into the limiting groove to fix the push plate 22 to the ship.

[0052] As one embodiment of this utility model, the push plate 22 is detachable, and there are multiple push plates 22 with different sizes. This means that the staff can select the appropriate push plate 22 according to the specific size and shape of the ship, which can meet the needs of ships of various sizes and improve the overall applicability. In addition, it can also avoid the push plate 22 being too small or too large, thus affecting the positioning effect of the ship and effectively improving the overall working stability.

[0053] As one embodiment of this utility model, a buffer is provided on the side of the push plate 22 away from the push rod 21, which can prevent hard contact between the push plate 22 and the ship and can protect the push plate 22 and the ship to a certain extent. The buffer can adopt various structures, such as rubber pads, silicone pads, etc.

[0054] As an embodiment of this utility model, a pressure sensor is provided on the push plate 22. When the positioning motor drives the push rod 21 and the push plate 22 to move toward the ship, the pressure sensor monitors the pressure value of the push plate 22 in real time. When the pressure value reaches the threshold, the positioning motor stops operating. This ensures that the push plate 22 provides effective thrust to the ship for positioning, while avoiding excessive thrust that could damage the ship, push rod 21, or push plate 22, thus improving the overall service life and operational stability.

[0055] As an embodiment of this utility model, three positioning mechanisms are provided on each side of the ship berth 2. The three positioning mechanisms are horizontally distributed along the side of the ship berth 2, that is, two inner positioning mechanisms are provided at the inner end of the ship berth 2, two middle positioning mechanisms are provided at the middle of the ship berth 2, and two outer positioning mechanisms are provided at the outer end of the ship berth 2. By applying thrust to multiple positions of the ship through multiple positioning mechanisms, the positioning effect of the ship can be further improved. For example, when the ship enters the ship berth 2 as a whole, the two inner positioning mechanisms position the stern of the ship, the two middle positioning mechanisms position the hull of the ship, and the two outer positioning mechanisms position the bow of the ship. The positioning mechanisms on both sides can adopt a one-to-one corresponding structure or an interleaved structure.

[0056] As one embodiment of this utility model, a universal joint is provided between the push plate 22 and the push rod 21. When the push rod 21 pushes the push plate 22 to abut against the ship, under the action of the universal joint, the push plate 22 can fit against the ship with the largest contact area, further improving the positioning effect of the ship.

[0057] As an embodiment of this utility model, the first displacement mechanism 5 includes a first track set on the support frame 12, a traveling wheel on the moving frame 31 that moves along the first track, and a first motor that drives the traveling wheel to move. The first motor drives the moving frame 31 to move along the first track to adjust the position of the lifting device 33 in the first direction. The second displacement mechanism 6 includes a second track set perpendicular to the direction of movement of the moving frame 31, a displacement trolley that moves along the second track, and a second motor that drives the displacement trolley to move. The second motor drives the displacement trolley to move along the second track to adjust the position of the lifting device 33 in the second direction. The first direction is perpendicular to the second direction. The first displacement mechanism 5 and the second displacement mechanism 6 cooperate with each other to adjust the horizontal position of the lifting device 33.

[0058] As one embodiment of this utility model, the lifting mechanism includes a third motor mounted on the second displacement mechanism 6 and a drum 71 driven by the third motor. A steel wire rope 72 is wound on the drum 71 and connected to the lifting device 33. The third motor drives the drum 71 to rotate, so as to wind and unwind the steel wire rope 72, thereby raising and lowering the lifting device 33. This allows the operator to adjust the vertical position of the lifting device 33 and the battery box 81 after determining the horizontal position of the lifting device 33, so as to lift or lower the battery box 81. Preferably, the lifting device 33 is provided with a movable pulley, and the steel wire rope 72 is wound on the movable pulley. When the steel wire rope 72 is wound, the movable pulley and the lifting device 33 rise; when the steel wire rope 72 is unwound, the movable pulley and the lifting device 33 descend.

[0059] As one embodiment of this utility model, there are four drums 71, four wire ropes 72, and four movable pulleys. The drums 71, wire ropes 72, and movable pulleys correspond one-to-one. The four movable pulleys are evenly arranged on the top of the lifting device 33, so that the lifting device 33 is subjected to uniform force. This can prevent the battery box 81 from tipping over due to uneven force on the lifting device 33, thus avoiding unnecessary damage to the battery box 81 and improving the overall safety and stability of use.

[0060] As an embodiment of this utility model, guide rail slider groups are provided between the battery swapping robot 3 and the support frame 12, and between the displacement trolley and the moving frame 31, and a guide rod is provided between the lifting device 33 and the second displacement mechanism 6.

[0061] In summary, this utility model provides a shipboard battery swapping station. A battery swapping robot 3 completes the transportation of battery boxes 81 between the ship's berth 2 and the battery compartment 4, eliminating the need for vehicle delivery of the battery boxes 81. This effectively reduces the battery swapping transfer process, simplifies the entire swapping procedure, and avoids the possibility of battery boxes 81 falling or being damaged due to cumbersome transfers, thus improving overall operational stability and safety. The use of a gantry-type battery swapping robot 3 instead of a conventional crane structure, allowing it to span across the battery compartment 4 and the ship's berth 2 to transport the battery boxes 81, not only improves the stability and safety of the swapping process but also effectively reduces the number of vehicles required for delivery. The robot 3 has a small footprint and can adjust the position of the battery box 81 in multiple directions through multi-axis linkage, so that it can be accurately installed on the ship or placed in the battery compartment 4, which effectively improves the battery swapping accuracy and realizes flexible intelligent battery swapping, thus improving the battery swapping efficiency. The turntable 334 and drive rod 335 replace the conventional motor to switch the position of the first limit part, realizing the automatic switching of the position of the first limit part, improving the working stability and efficiency. The positioning mechanism positions the ship, which can not only ensure that the ship accurately docks at the ship docking position 2, but also keep the ship stationary during the battery swapping process, avoiding the ship from swaying, thus effectively improving the battery swapping accuracy.
