[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0022] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a device for mutual charging between ships, including a charging gun 7, a hoist 2 installed on a first electric boat 1 for hoisting the charging gun 7 to a second electric boat 13, and a first connecting component installed on the hoist 2. The second electric boat 13 is provided with a charger 8 that cooperates with the charging gun 7 and a second connecting component connected to the first connecting component.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the charging device is installed on the main body of the first electric boat 1 and can charge the second electric boat 13. The hoist 2 is used to lift the charging gun 7 on the first electric boat 1 and place it on the charger 8 installed on the second electric boat 13, so as to facilitate charging of the second electric boat 13. Through the cooperation of the first connecting component and the second connecting component, the first electric boat 1 and the second electric boat 13 can be connected to prevent the charging cable 15 from being broken during the charging process.

[0025] like Figure 1 and Figure 2 As shown, the first connecting assembly includes a lifting chain connected to the hoist 2 and a hook 5 connected to the lifting chain. The upper end of the lifting chain is connected to the hoist 2, and the lower end of the lifting chain is connected to the hook 5. The second connecting assembly includes a hook post 6, the upper end of which has a hook hole that mates with the hook 5. Through the operation of the hoist 2, the lifting chain and hook 5 can be raised and lowered, facilitating connection or disconnection with the second connecting assembly by the operator.

[0026] like Figure 1 and Figure 2 As shown, the second connecting assembly also includes a base 9 mounted on the second electric boat 13, with the hook post 6 and charger 8 fixedly mounted on the base 9. The hook post 6 is vertically positioned, and the hook hole is a through hole at the upper end of the hook post 6, ensuring that the hook 5 can be smoothly inserted. The hook 5 is inserted into the hook hole to connect the two electric boats. This stable connection between the two electric boats ensures that the charging cable 15 is not easily broken during charging due to the secure connection, thus improving safety. The connection and disconnection process is relatively simple and convenient thanks to the cooperation of the hoist 2, the chain, and the hook 5.

[0027] like Figure 1 and Figure 2As shown, a reel 3 is installed on the hoist 2. The charging cable 15, connected to the charging gun 7, is wound on the reel 3. The reel 3 is rotatably mounted on the hoist 2. One end of the charging cable 15 is connected to the charging gun 7, and the other end is connected to the power supply system on the first electric boat 1. The reel 3 allows for neat storage and management of the charging cable 15, preventing it from becoming tangled and improving both safety and aesthetics. When charging the second electric boat 13 is required, the hoist 2 operates the chain and hook 5 to bring the charging gun 7 (connected to the charging cable 15) to the vicinity of the second electric boat 13. The charging gun 7 is inserted into the charging port of the charger 8 on the second electric boat 13. At this time, the charging cable 15 is in a stretched state, but due to the rotation of the reel 3, it can extend smoothly without restriction. After the charging gun 7 is connected to the charging port of the second electric boat 13, power is transmitted from the power supply system of the first electric boat 1 to the second electric boat 13 through the charging cable 15 for charging. After charging is complete, disconnect the charging gun 7 from the charging interface of the second electric boat 13, and retract the charging gun 7 (and the charging cable 15 wound on it) by operating the hoist 2.

[0028] As a preferred option, such as Figure 1 and Figure 2 As shown, a protective cover 4 is installed on the hoist 2, and the charging cable 15 passes through the protective cover 4. Multiple protective covers 4 are provided, and the charging cable 15 passes through each protective cover 4 sequentially. The protective covers 4 are located between the cable reel 3 and the charging gun 7. The charging cable 15 starts from the cable reel 3, passes through each protective cover 4 sequentially, and finally reaches the charging gun 7. The protective covers 4 are used to restrict the position of the charging cable 15 and provide a certain degree of protection against damage or interference. Multiple protective covers 4 are provided, and the protective covers 4 can be made of strong and durable materials, such as metal or high-strength plastic, to resist external impacts and abrasion.

[0029] As a preferred option, such as Figure 1 and Figure 2 As shown, a roller 14 is installed inside the protective cover 4. The roller 14 is rotatable, and its axis is parallel to the axis of the cable reel 3. The roller 14 is cylindrical, and its outer surface is designed to contact the charging cable 15. The use of the roller 14 significantly reduces friction between the charging cable 15 and the protective cover 4, lowering the risk of damage to the charging cable 15 due to friction. The roller 14 provides a smooth transmission path for the charging cable 15, allowing it to be extended and retracted more quickly, thus improving the efficiency of the charging operation.

[0030] like Figure 1 and Figure 2As shown, the charger 8 is used to transfer electrical energy from the first electric boat 1 to the second electric boat 13. The charger 8 and the energy storage converter cabinet 10 are fixedly mounted on the base 9. The energy storage converter cabinet 10 is used to realize the controllable conversion of bidirectional current. The battery rack 11 on the second electric boat 13 is used to store the swapped battery 12, which provides replenishment power to the electric boat. The charger 8 is electrically connected to the energy storage converter cabinet 10, and the energy storage converter cabinet 10 is electrically connected to the swapped battery 12.

[0031] The charging process is as follows: the second electric boat 13 approaches the first electric boat 1, the hoist 2 of the first electric boat 1 transmits the charging gun 7 to the charging interface of the charger 8 of the second electric boat 13, and the operator connects the hook 5 to the mounting hole of the mounting post 6; then the operator inserts the charging gun 7 into the charging interface of the charger 8 of the second electric boat 13 to directly supply power to the second electric boat 13, or the battery of the second electric boat 13 can be charged through the energy storage converter cabinet 10.

[0032] The ship-to-ship charging device described above has the following beneficial effects:

[0033] 1. It can replenish energy while the electric boat is in motion, thus improving the efficiency of electric boat use.

[0034] 2. It can make the most of peak-valley low-price electricity, and the electricity can be sold through mutual transmission, which improves economic efficiency.

[0035] 3. The charging cable 15 has a roller 14 at the bottom, which can reduce wear when the cable shakes and improve the service life of the charging cable 15.

[0036] 4. The hook 5 connects the two boats, avoiding pulling on the charging cable 15 and protecting the charging cable 15.

[0037] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
