[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] To reduce exhaust and noise pollution during ship operation and lower operating costs, electric ships are becoming increasingly popular in inland waterway transportation, coastal shipping, marine scientific research, and fisheries. Electric ships are primarily powered by electricity, with the battery pack as their core component. The battery pack consists of multiple battery packs connected in series.

[0035] When an electric vessel is undergoing battery replacement, it docks at a pier. The depleted battery packs on the electric vessel are then hoisted to a charging station on the pier for charging using the pier's hoisting equipment. The fully charged battery packs in the charging station are then hoisted back onto the electric vessel for replacement. However, in current electric vessels, the depleted battery packs often need to be manually removed from their installation locations on the electric vessel and moved to the hoisting location to facilitate installation by the hoisting equipment. Simultaneously, the fully charged battery packs, already hoisted to the hoisting location on the electric vessel, are moved to the installation location for installation. This manual handling of the battery packs during the battery replacement process is time-consuming and labor-intensive.

[0036] Based on this, in order to improve the above technical problems, the utility model provides a battery exchange system and an electric ship, which facilitates the movement of battery packs on electric ships without the need for manual movement of the battery packs, thereby improving the current problem of time-consuming and labor-intensive operation of electric ships.

[0037] The overall structure, working principle and technical effects of a battery replacement system and an electric ship provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0038] Please refer to Figure 1 and Figure 2The present invention provides an electric ship, comprising a deck 100 and a power exchange system 200. The power exchange system 200 is arranged on the deck 100 of the electric ship, and the power exchange system 200 is connected to the power facilities on the electric ship. When replacing the battery pack on the electric ship, the power exchange system 200 is used to drive the battery pack to move, and then move the depleted battery pack to the lifting position for lifting by the lifting equipment on the dock, and move the fully charged battery pack lifted to the electric ship into the power exchange system 200 for installation, thereby connecting the battery pack to the power facilities on the electric ship and feeding power to the electric ship. This improves the problem that manual handling of battery packs is required when replacing batteries in electric ships, which makes the battery replacement process time-consuming and labor-intensive.

[0039] Please refer to Figure 1 and Figure 2 The present invention also provides a battery exchange system 200, which is applied to battery exchange ships, facilitates battery exchange operations on electric ships, improves the battery exchange efficiency of electric ships, and improves the time-consuming and labor-intensive battery exchange process of electric ships, thereby shortening the time for electric ships to dock for battery exchange and improving the working efficiency of battery exchange ships.

[0040] The present invention provides a battery exchange system 200 including a mounting frame 210, a transfer assembly 220, and a mobile assembly 230. The mounting frame 210 has a mounting cavity 211 therein for accommodating and installing a battery pack. The mounting frame 210 connects the battery pack installed in the mounting cavity 211 to the electrical facilities on the electric vessel, thereby feeding power to the electrical facilities on the electric vessel through the battery pack installed in the mounting cavity 211. The transfer assembly 220 is disposed on one side of the mounting frame 210 and is used to carry the battery pack. In this embodiment, the transfer assembly 220 is disposed on the deck 100 of the electric vessel, and the transfer assembly 220 is located at a hoisting position when the hoisting equipment hoists the battery pack. The mobile component 230 is set on the mounting frame 210, one end of the mobile component 230 is located in the mounting cavity 211, and the other end of the mobile component 230 extends outside the mounting cavity 211 and is vertically opposite to the transfer component 220. The mobile component 230 is used to move the battery pack carried on the transfer component 220 to the mounting cavity 211, and move the battery pack in the mounting cavity 211 to the transfer component 220.

[0041] When replacing the battery of an electric vessel, the depleted battery pack in the installation cavity 211 is moved to the transfer component 220 by the mobile component 230, and the depleted battery pack on the transfer component 220 is hoisted to the charging station on the dock for charging by the lifting equipment on the dock. The fully charged battery pack is then hoisted to the transfer component 220 by the lifting equipment, and the fully charged battery pack on the transfer component 220 is moved to the installation cavity 211 by the mobile component 230 for installation, thereby realizing the battery replacement of the electric vessel. By setting up the transfer component 220 and the mobile component 230, there is no need to manually move the battery pack when replacing the battery of the electric vessel, which improves the time-consuming and labor-intensive problem of manually moving the battery pack and improves the efficiency of battery replacement.

[0042] The mounting frame 210 defines a mounting cavity 211, and the end of the mounting frame 210 near the transfer assembly 220 is open, thereby facilitating the movement of the battery pack between the transfer assembly 220 and the mounting cavity 211 by the moving assembly 230. In this embodiment, the shape and structure of the mounting frame 210 are not limited; it only needs to have a mounting cavity 211 for accommodating and mounting the battery pack, and the end of the mounting frame 210 near the transfer assembly 220 is open.

[0043] In this embodiment, to facilitate installation of the battery pack within the mounting cavity 211, a charging base 212 is provided within the mounting cavity 211. The charging base 212 is used to support the battery pack and connect the battery pack to external power facilities. Furthermore, to increase the rated capacity of the battery pack and facilitate heat dissipation from the battery pack, in some optional embodiments, the charging base 212 is provided on both sides of the mounting cavity 211. When the battery packs are installed on the charging base 212, multiple battery packs are arranged on both sides of the mounting cavity 211, facilitating air flow within the mounting cavity 211, thereby cooling the battery packs.

[0044] For further information, please refer to Figure 1 and Figure 2 In order to facilitate the connection between the battery pack and the electrical facilities on the electric ship, a distribution room 300 is set on one side of the mounting frame 210. The distribution room 300 is connected to the charging base 212, so that the electrical facilities on the electric ship can be controlled through the distribution room 300 and the power supply of the battery pack can be regulated.

[0045] Please refer to Figure 1 and Figure 2In this embodiment, the transfer assembly 220 includes a transfer base, which is arranged outside the mounting frame 210, and is used to carry the battery pack. The transfer base is directly opposite to the charging base 212 in the mounting cavity 211. In this embodiment, the charging base 212 is provided on both sides of the mounting cavity 211, so that two transfer bases are also provided and correspond to the two charging bases 212 respectively. Furthermore, a full-charge station and a low-charge station are provided on the transfer base. The full-charge station is used to carry a fully charged battery pack, and the low-charge station is used to carry a low-charge battery pack. By providing two types of stations on the transfer base, the battery pack can be easily circulated on the transfer base.

[0046] Please refer to Figure 1 and Figure 2 In some optional embodiments, the moving assembly 230 includes a clamping member 231 and a driving member 232. The clamping member 231 is used to clamp and fix the battery pack. In this embodiment, the clamping member 231 is a battery-changing robot. In other optional embodiments, the clamping member 231 can also be a structure for clamping, such as a manipulator or a mechanical gripper, which is not limited in the present invention. The driving member 232 is provided on the mounting frame 210 and is located in the mounting cavity 211. The driving member 232 is used to drive the clamping member 231 to move within the mounting cavity 211 and between the transfer assembly 220. Furthermore, through the cooperation between the driving member 232 and the clamping member 231, the fully charged battery pack on the transfer assembly 220 is clamped and moved into the mounting cavity 211, and the low-charged battery pack in the mounting cavity 211 is clamped and moved to the transfer assembly 220.

[0047] For further information, please refer to Figure 1 and Figure 2 The driving member 232 includes a moving seat, a first moving part and a second moving part. The moving seat is arranged on the inner top wall of the mounting frame 210 along the length direction of the mounting frame 210. The clamping member 231 is arranged on the moving seat and moves along the length direction of the moving seat. The clamping member 231 can be moved on the moving seat by a driving method such as a gear rack, a rodless electric cylinder, a gear chain, etc., which is not limited in this embodiment. The first moving part is arranged on the mounting frame 210 and connected to the moving seat. The first moving part is used to drive the moving seat to move on the top wall of the mounting frame 210 along a direction perpendicular to the length direction of the moving seat. The first moving part can be a driving structure such as a gear rack, an electric cylinder, a gear chain, etc., which is not limited in this embodiment. The second moving part is arranged on the moving seat and connected to the clamping member 231. The second moving part is used to drive the clamping member 231 to move in the vertical direction, thereby driving the clamping member 231 close to or away from the battery pack, thereby facilitating the clamping of the battery pack by the clamping member 231. The second moving part can be a gear rack structure, a winch structure, or the like, and it only needs to drive the clamping member 231 to move in the vertical direction, which is not limited in this embodiment.

[0048] Please refer to Figure 1 and Figure 3 In some optional embodiments, the mounting bracket 210 in the battery exchange system 200 is directly mounted on the deck 100 of the electric vessel, thereby achieving the effect of facilitating the installation of the battery exchange system 200 in the present invention on the electric vessel. Furthermore, a fire water tank is provided on the deck 100 and directly below the mounting bracket 210. Fire water is stored in the fire water tank, and a delivery port 240 is provided at the bottom of the mounting bracket 210. The delivery port 240 connects the interior of the installation cavity 211 with the fire water tank. When a fire occurs in a battery pack in the installation cavity 211, the mobile component 230 can be used to clamp the burning battery pack and move it above the fire water tank, and then the burning battery pack can be dropped into the fire water tank for fire extinguishing, thereby improving the safety of the battery exchange system 200 and the electric vessel.

[0049] Please refer to Figure 1 and Figure 3 Furthermore, a flap 241 is rotatably provided on the mounting frame 210 and located at the delivery port 240. A piston cylinder 242 is also hingedly provided on the mounting frame 210 at the delivery port 240. The end of the piston rod of the piston cylinder 242 is hinged to the flap 241, so that the flap 241 is driven to flip by the extension and contraction of the piston cylinder 242, thereby blocking or opening the delivery port 240, so that the battery pack can be smoothly delivered into the fire water tank when the battery pack catches fire, and at the same time, the bottom of the mounting frame 210 can be kept intact when the battery pack is working normally, so that the operator can enter and exit the mounting frame 210 normally.

[0050] In summary, the battery swap system 200 of the present invention can move a fully charged battery pack hoisted onto the deck 100 by a hoisting device into the mounting rack 210 for installation, and can also move a depleted battery pack out of the mounting rack 210 to facilitate hoisting by the hoisting device. This eliminates the need for operators to manually carry depleted and fully charged battery packs during the battery swap process, thereby improving battery swap efficiency. The electric vessel of the present invention utilizes the aforementioned battery swap system 200, enabling rapid battery swapping, shortening the docking and battery swapping time of the electric vessel and improving the operating efficiency of the electric vessel.

[0051] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
