Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Unless otherwise defined, 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; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0057] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0058] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0060] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0061] The inventors discovered that, limited by the energy density of current battery technology, the density of charging infrastructure, and the complexity of ship range planning, electric ships face the challenge of insufficient range during long-distance voyages or complex operating conditions. When an electric ship runs out of power during its journey, it will be unable to reach a charging station or battery swapping station for recharging. Currently, the rescue of ships with depleted batteries typically involves using fuel-powered tugboats to tow them to a dock for recharging. However, since rescue vessels are fuel-powered, this not only pollutes the environment with exhaust emissions but also results in high fuel consumption and costs.

[0062] Based on the above considerations, and to address the problems of environmental pollution and high fuel consumption associated with fuel-powered rescue vessels, this application provides an electric rescue vessel. The electric rescue vessel includes a vessel carrier and rescue equipment. The rescue equipment is mounted on the vessel carrier. The rescue equipment includes a power module, a charging system, and a cable transmission system. The power module supplies power to the electric rescue vessel, and after energy conversion through the charging system, the electrical energy is transmitted to the vessel to be rescued via the cable transmission system to power the vessel.

[0063] In the aforementioned electric rescue vessels, on the one hand, the power module can supply power to the vessel itself; on the other hand, after energy conversion through the charging system, the power can be transmitted to the vessel awaiting rescue via a cable transmission system, thus powering the vessel. Once charged, the vessel can continue sailing without deviating from its predetermined route, which helps shorten the voyage distance. Furthermore, compared to fuel-powered vessels, electric rescue vessels are electrically powered, producing zero exhaust emissions and no air pollution during navigation, and the cost of electricity is typically lower than the cost of fuel. In addition, through the energy conversion of the charging system, the power provided by electric rescue vessels can meet the electricity needs of various vessels with depleted batteries.

[0064] Please see Figures 1 to 3 , Figure 13 This application provides an electric rescue vessel 1000. The electric rescue vessel 1000 includes a rescue device 100 and a vessel carrier 200. The rescue device 100 is disposed on the vessel carrier 200. The rescue device 100 includes a power module 10, a charging system 20, and a cable transmission system 30. The power module 10 supplies power to the electric rescue vessel 1000, and after energy conversion through the charging system 20, the power is transmitted to the vessel 2000 to be rescued via the cable transmission system 30, thus supplying power to the vessel 2000 to be rescued.

[0065] Specifically, the electric rescue vessel 1000 refers to a rescue vessel powered by electricity. The electric rescue vessel 1000 provides rescue services to the vessel 2000 awaiting rescue via a rescue device 100. The electric rescue vessel 1000 includes a vessel carrier 200, on which the rescue device 100 is mounted.

[0066] The rescue device 100 includes a power module 10, a charging system 20, and a cable transmission system 30.

[0067] As an example, power module 10 can be a box-type power supply. A box-type power supply is an integrated and modular power device that integrates power modules, control systems, heat dissipation devices, protection units, and fire protection facilities into a protective enclosure. It features flexible deployment, strong environmental adaptability, and reliability.

[0068] The charging system 20 is a device that converts electrical energy into a form suitable for charging batteries and precisely controls the charging process. Its core function is to provide efficient and reliable power supply to the batteries. For example, the charging system 20 can regulate the voltage or current of the power output from the power module 10 to adapt to the charging requirements of the vessel 2000 awaiting rescue.

[0069] The cable transmission system 30 is a device for transmitting electrical energy, used to transmit electrical energy from the power source to the power consumer in real time.

[0070] In this embodiment, the power module 10 can be installed on the deck of the ship carrier 200. With the bow of the ship carrier 200 as forward and the stern as aft, the charging system 20 can be installed in front of the power module 10, and the cable transmission system 30 can be installed at either the bow or stern. The power module 10, charging system 20, and cable transmission system 30 can be connected sequentially via cables.

[0071] Please combine Figure 4 On the one hand, the power module 10 carried on the electric rescue vessel 1000 can supply power to the vessel itself; on the other hand, after the power is converted by the charging system 20, the power can be transmitted to the vessel 2000 to be rescued by the cable transmission system 30 to supply power to the vessel 2000. In this way, the power provided by the electric rescue vessel 1000 through the power conversion of the charging system 20 can meet the power needs of different vessels with depleted power.

[0072] Research has found that, among the relevant technologies, rescue vessels using fuel oil not only emit exhaust gases that pollute the environment, but also consume a lot of fuel and are costly.

[0073] The embodiment of this application uses an electric rescue vessel 1000, which is powered by electricity, emits zero exhaust gas during navigation, causes no air pollution, and has a low cost.

[0074] Please see Figure 1 and Figure 2 In some embodiments, the power module 10 is connected to the charging system 20. The charging system 20 can be used to perform voltage conversion and / or power conversion on the electrical energy output by the power module 10.

[0075] Specifically, the charging system 20 can perform voltage conversion and / or power conversion on the electrical energy output from the power module 10 through power electronic topology design and intelligent control strategies. For example, the charging system 20 can achieve stable regulation of the output voltage over a wide range (e.g., 10V-1000V) through a DC-DC converter or AC-DC / DC-AC multi-stage conversion combined with closed-loop feedback control. The charging system 20 can achieve dynamic power distribution and adjustment by connecting multiple power modules in parallel (e.g., battery packs, power modules) or by employing digital control technology to cover load demands ranging from a few watts to megawatts.

[0076] Research has revealed that, among the relevant technologies, rescue vessels lack charging systems, making it impossible to meet the charging needs of depleted vessels with wide power and voltage ranges.

[0077] In this embodiment of the application, the voltage conversion and / or power conversion of the charging system 20 can achieve wide voltage and wide power output, thereby meeting the power needs of ships with low power and different voltages and power.

[0078] Please see Figure 1 , Figure 2 and Figure 13 In some embodiments, the cable transmission system 30 includes a charging cable 31 and a charging gun 32. The charging system 20 is connected to the charging cable 31, which is connected to the charging gun 32, which is used to electrically connect to the vessel 2000 to be rescued.

[0079] Specifically, the outer layer of the charging cable 31 can be made of wear-resistant, tensile-resistant, waterproof, and corrosion-resistant materials, while the core of the charging cable 31 can be made of highly conductive copper, aluminum, or other materials. One end of the charging cable 31 is connected to the charging system 20, and the other end is connected to the charging gun 32. The charging gun 32 is used to electrically connect to the vessel 2000 to be rescued. For example, the charging gun 32 can be used to charge the box-type power supply plugged into the vessel 2000 to the box-type power supply.

[0080] Please see Figures 5 to 8 In some embodiments, the cable transmission system 30 further includes an actuator 33, a first drive assembly 34, a second drive assembly 35, a third drive assembly 36, and a first electronic control unit 37. The actuator 33 is used to transmit the charging cable 31 and the charging gun 32 to the vessel 2000 awaiting rescue. The first electronic control unit 37 is used to: control the first drive assembly 34 to drive the actuator 33 to rotate about a first direction; control the second drive assembly 35 to drive the actuator 33 to rotate about a second direction; and control the third drive assembly 36 to drive the actuator 33 to move along a third direction. The first direction, the second direction, and the third direction are mutually perpendicular, and the third direction is the length direction of the actuator 33.

[0081] It is understandable that there is usually a certain distance between the electric rescue vessel 1000 and the vessel to be rescued 2000, and this distance may dynamically change due to sea conditions, vessel size, etc. Manually passing the charging cable 31 and charging gun 32 would not only be inefficient, but also pose a risk of falling due to the vessel's swaying.

[0082] In this embodiment of the application, the charging cable 31 and the charging gun 32 can be transmitted to the vessel 2000 to be rescued by the actuator 33. Then, the crew members on the vessel 2000 to be rescued can grab the charging gun 32 and plug the charging gun 32 into the charging socket of the box-type power supply on the vessel 2000 to charge the box-type power supply on the vessel 2000 to be rescued.

[0083] Specifically, the first direction is as follows Figure 5 In the X direction, the second direction is as follows Figure 5 In the Y direction, the third direction is as follows Figure 5The Z direction is defined in the figure. The first direction, the second direction, and the third direction are perpendicular to each other, and the third direction is the length direction of the actuator 33.

[0084] The first electronic control unit 37 can be an electronic control box. The first electronic control unit 37 is connected to the first drive assembly 34, the second drive assembly 35 and the third drive assembly 36 respectively.

[0085] The first electronic control unit 37 can control the first drive assembly 34 to operate, thereby driving the actuator 33 to rotate around a first direction. That is, to realize the rotational movement of the actuator 33 in the horizontal direction, so that the actuator 33 can adjust its direction on the horizontal plane in order to more accurately align with the charging base on the vessel 2000 to be rescued.

[0086] The first electronic control unit 37 can control the second drive assembly 35 to drive the actuator 33 to rotate around the second direction. That is, to realize the pitch movement of the actuator 33 in the height direction, so that the actuator 33 can adjust its angle in the vertical plane to adapt to the charging base on the rescue vessel 2000 at different heights.

[0087] The first electronic control unit 37 can control the third drive assembly 36 to operate, thereby driving the actuator 33 to move along a third direction. That is, to achieve linear movement of the actuator 33 in its own length direction, so that the actuator 33 can move back and forth in the horizontal direction to adjust its relative position with the vessel 2000 to be rescued, ensuring that the charging gun 32 can be connected to the charging socket on the vessel 2000 to be rescued.

[0088] In the above technical solution, by controlling the first drive component 34, the second drive component 35 and the third drive component 36, the actuator 33 can be driven to move in multiple degrees of freedom, so as to accurately transmit the charging cable 31 and the charging gun 32 to the corresponding positions on the vessel 2000 to be rescued.

[0089] Please see Figures 5 to 7 In some embodiments, the cable transmission system 30 further includes a first base 38 and a first support member 39. The first support member 39 is disposed on the first base 38 and is used to support the actuator 33. The first drive assembly 34 includes a first drive motor (not shown), a first reducer (not shown), and a drive gear (not shown). The first electronic control unit 37 is used to control the operation of the first drive motor and transmit power to the drive gear through the first reducer, so as to drive the actuator 33 to rotate around a first direction by driving the first support member 39.

[0090] Specifically, the first base 38 can serve as the supporting element for all functional components in the cable transmission system 30. Each functional component is supported on the first base 38 and can be independently assembled into a module installed on the bow deck and connected to the deck by bolts. The first support member 39 can be a slewing bearing. The first support member 39 is installed on the first base 38 and is used to support the actuator 33.

[0091] The first drive motor can be a servo motor, used to provide high-precision, high-dynamic-response rotational power. The first reducer is used to reduce speed and increase torque. The drive gear can be a pinion, used to transmit the torque output by the first reducer to the load end (e.g., the first support member 39).

[0092] The first electronic control unit 37 can control the first drive motor to work and transmit power to the drive gear through the first reducer to drive the first support member 39 to rotate, thereby driving the actuator 33 to rotate in the horizontal direction.

[0093] Please see Figures 5 to 7 In some embodiments, the cable transmission system 30 further includes a mounting base 40, a first reel 41, a second drive motor 42, and a second reducer 43. The first reel 41 is rotatably mounted on the mounting base 40 and is used to wind the charging cable 31. A first electronic control unit 37 is used to control the operation of the second drive motor 42 and transmit power to the second reducer 43 to drive the first reel 41 to rotate.

[0094] Specifically, the mounting base 40 is mounted on the first support member 39. The first reel 41 can be rotatably mounted on the mounting base 40 via the second rotating shaft 44. The charging cable 31 is wound in the groove of the first reel 41. The second drive motor 42 can be a servo motor. The first electronic control unit 37 can control the operation of the second drive motor 42, and the power of the second drive motor 42 is transmitted to the second reducer 43, which then drives the first reel 41 to rotate.

[0095] Please see Figure 5 and Figure 6 In some embodiments, the actuator 33 includes a transmission arm 331, and the second drive assembly 35 includes a first telescopic member 351. One end of the transmission arm 331 is rotatably connected to the end 401 of the fixed base 40, and the other end of the transmission arm 331 is hinged to one end of the first telescopic member 351, the other end of the first telescopic member 351 being hinged to the side 402 of the fixed base 40. A first electronic control unit 37 is used to control the operation of the first telescopic member 351 to drive the actuator 33 to rotate about a second direction.

[0096] Specifically, the transmission arm 331 can be a large arm. The first telescopic member 351 can be a telescopic hydraulic cylinder or a telescopic electric cylinder. One end of the transmission arm 331 can be rotatably connected to the end 401 of the fixed base 40 via a pin 333, and the other end of the transmission arm 331 is hinged to one end of the first telescopic member 351. The other end of the first telescopic member 351 is hinged to the side 402 of the fixed base 40 (the side 402 of the fixed base 40 can be provided with a mounting seat 403 for hinge). The first electronic control unit 37 can control the operation of the first telescopic member 351. The linear motion of the first telescopic member 351 is converted into the rotational motion of the transmission arm 331 through the hinge point, thereby realizing the pitching motion of the actuator 33 in the height direction.

[0097] In some embodiments, the actuator 33 further includes a telescopic arm 332, which is embedded within the transmission arm 331. The third drive assembly 36 includes a second telescopic member 361. One end of the second telescopic member 361 is hinged to the transmission arm 331, and the other end of the second telescopic member 361 is hinged to the telescopic arm 332. The first electronic control unit 37 is used to control the operation of the second telescopic member 361 to drive the actuator 33 to move in a third direction.

[0098] Specifically, the transmission arm 331 can have an internally hollow structure to accommodate the telescopic arm 332. A nylon sleeve can also be installed on the inner side of the transmission arm 331, and the outer side of the telescopic arm 332 contacts the nylon sleeve, achieving relative movement through sliding friction. The second telescopic member 361 can be a telescopic hydraulic cylinder or a telescopic electric cylinder. One end of the second telescopic member 361 is hinged to the inner side of the transmission arm 331, and the other end is hinged to the inner side of the telescopic arm 332, forming a double-hinged sliding composite mechanism. The first electronic control unit 37 can control the operation of the second telescopic member 361. The linear motion of the second telescopic member 361 is converted into the telescopic motion of the telescopic arm 332 through the hinge point, thereby realizing the forward and backward movement of the actuator 33 in the horizontal direction.

[0099] In addition, please see Figure 7 When the first telescopic member 351 and the second telescopic member 361 are telescopic hydraulic cylinders, the cable transmission system 30 may further include a hydraulic station 48. The hydraulic station 48 is mounted on the first base 38 and can provide power to the first telescopic member 351 and the second telescopic member 361. It also precisely controls the telescopic movement and stroke of the hydraulic cylinders through a proportional regulating valve and a solenoid directional valve. This allows for precise control of the hydraulic cylinder movement, and consequently, precise control of the movement of the actuator 33.

[0100] The cable transmission system 30 may also include a third support 49, which can be used to support the actuator 33.

[0101] The cable transmission system 30 may also include a slip ring box 50. The slip ring box 50 can be installed at each drive component as needed. The slip ring box 50 enables continuous and stable power transmission between rotating and stationary components through the sliding contact between the conductive ring and the brush.

[0102] Please see Figure 6 In some embodiments, the cable transmission system 30 further includes a grooved wheel 45, a third drive motor 46, and a third reducer 47. The grooved wheel 45 is disposed on the transmission arm 331 and is used to wind the charging cable 31. The first electronic control unit 37 is used to control the operation of the third drive motor 46 and transmit power to the third reducer 47 to drive the grooved wheel 45 to rotate.

[0103] Specifically, the grooved wheel 45 can be a nylon grooved wheel. The grooved wheel 45 is located on the side of the transfer arm 331 near the first reel 41. After the charging cable 31 exits from the first reel 41, it enters the groove of the grooved wheel 45. The third drive motor 46 can be a servo motor. The first electronic control unit 37 can control the operation of the third drive motor 46. The power of the third drive motor 46 is transmitted to the third reducer 47, which then drives the grooved wheel 45 to rotate, thereby moving the charging cable 31 and realizing the winding and unwinding of the charging cable 31.

[0104] Through the cooperation of the first drive motor, the second drive motor 42, the third drive motor 46, the first telescopic member 351, and the second telescopic member 361, the charging cable 31 and the charging gun 32 can be transferred to the vessel 2000 to be rescued. The crew members on the vessel 2000 can then grab the charging gun 32 and plug it into the charging socket of the box-type power supply on the vessel 2000 to charge the box-type power supply on the vessel 2000.

[0105] Please see Figures 9 to 11 In some embodiments, the rescue device 100 further includes a towing assembly 60. The towing assembly 60 includes an adjustable-length towing member 61 for physically connecting to the vessel 2000 to be rescued.

[0106] Specifically, the towing assembly 60 can be installed at the stern. It can be understood that when the cable transmission system 30 is also installed at the stern, the towing assembly 60 and the cable transmission system 30 can be arranged side by side at the stern.

[0107] As an example, the traction assembly 60 can be a wire rope winch, and the traction component 61 can be a wire rope. A wire rope winch is a mechanical device used for the winding, unwinding, storage, and management of wire ropes. It can consist of a drum, a drive mechanism, a support frame, and protective components, and can efficiently and reliably handle the unwinding and retrieval of long-distance wire ropes.

[0108] In this embodiment, the wire rope winch can extend or retract the length of the wire rope according to requirements, such as the distance between the electric rescue vessel 1000 and the vessel 2000 to be rescued.

[0109] Research revealed that the rescue vessels lacked a wire rope traction device, making it impossible to tow the disabled vessel back to the dock.

[0110] In this embodiment, the towing assembly 60 can be used to rescue the vessel 2000, such as a disabled fuel-powered vessel or a disabled electric vessel, and tow it back to the dock or shipyard. In this case, the electric rescue vessel 1000 can act as a tugboat.

[0111] Please see Figures 9 to 11 In some embodiments, the traction assembly 60 further includes a second base 62, a second support member 63, a second reel 64, a fourth drive assembly 65, and a second electronic control unit 66. The second support member 63 is disposed on the second base 62. The second reel 64 is rotatably disposed on the second support member 63 and is used to wind the traction member 61. The fourth drive assembly 65 is connected to the second reel 64. The second electronic control unit 66 controls the operation of the fourth drive assembly 65 to drive the second reel 64 to rotate.

[0112] Specifically, the second base 62 can serve as a supporting element for the aforementioned second support member 63, second reel 64, fourth drive assembly 65, and second electronic control unit 66. The second support member 63 can be a support frame. The second support member 63 is mounted on the second base 62. The second reel 64 can be rotatably mounted on the second support member 63 via the first rotating shaft 67. The traction member 61 is wound around the second reel 64. The fourth drive assembly 65 is connected to the second reel 64. The second electronic control unit 66 can be an electronic control box. The second electronic control unit 66 is connected to the fourth drive assembly 65. The second electronic control unit 66 can control the operation of the fourth drive assembly 65 to drive the second reel 64 to rotate. For example, it can drive the second reel 64 to rotate forward or backward to achieve the winding and unwinding of the traction member 61.

[0113] In practical applications, for a disabled fuel-powered vessel or a disabled electric vessel (including vessels with depleted power), the towing member 61 can be attached to the bow of the disabled vessel. The second electronic control unit 66 controls the fourth drive assembly 65 to operate, driving the second reel 64 to rotate and releasing the towing member 61 so that the electric rescue vessel 1000 can reach a safe distance from the disabled vessel. Then, the electric rescue vessel 1000 tows the disabled vessel to a dock or dry dock, acting as a tugboat.

[0114] Please see Figure 10In some embodiments, the fourth drive assembly 65 includes a fourth drive motor 651, a coupling 652, and a fourth reducer 653. The coupling 652 connects the fourth drive motor 651 and the fourth reducer 653. The second electronic control unit 66 controls the operation of the fourth drive motor 651 and transmits power to the fourth reducer 653 through the coupling 652 to drive the second reel 64 to rotate.

[0115] Specifically, the fourth drive motor 651 can be an asynchronous motor. The fourth drive motor 651 can serve as a power source to convert electrical energy into mechanical energy to provide rotational power.

[0116] The coupling 652 can be a rigid coupling, a flexible coupling, etc., and is not limited here. The coupling 652 connects the fourth drive motor 651 and the fourth reducer 653, and can be used to transmit torque and rotational motion, while compensating for the relative displacement between the two shafts, such as axial, radial, and angular errors.

[0117] The fourth reducer 653 is used to reduce speed and increase torque to meet the load's requirements for speed and torque.

[0118] In the above technical solution, the second electronic control unit 66 controls the fourth drive motor 651 to operate, and transmits the power of the fourth drive motor 651 to the fourth reducer 653 through the coupling 652. The fourth reducer 653 then drives the second reel 64 to rotate. In this way, through the coordinated work of the fourth drive motor 651, the coupling 652, and the fourth reducer 653, the power can be efficiently and stably transmitted from the fourth drive motor 651 to the second reel 64. The rotation of the second reel 64 then enables the winding and unwinding of the traction component 61.

[0119] In some embodiments, the rescue device 100 further includes any one or more of a visual recognition system, a laser ranging system, a lidar system, a navigation and positioning system, and an automatic navigation system.

[0120] Specifically, the visual recognition system, laser ranging system, and lidar system can be installed at the bow or stern of the electric rescue device 100, while the navigation and positioning system and automatic navigation system can be mounted on the electric rescue device 100.

[0121] The aforementioned visual recognition system, laser ranging system, lidar system, navigation and positioning system, and automatic navigation system can be used to assist in the process of the electric rescue vessel 1000 supplying power to the vessel 2000 to be rescued, or to assist in the process of the electric rescue vessel 1000 towing the vessel 2000 to be rescued, or to assist in the process of the electric rescue vessel 1000 following the vessel 2000 to perform synchronous automatic navigation.

[0122] The navigation and positioning system can be the Global Positioning System (GPS). GPS is a satellite navigation and positioning system that operates 24 / 7, has high-precision positioning capabilities, and achieves global coverage. Through the coordinated work of satellite signal transmission and ground receiving equipment, the system can accurately determine the three-dimensional position information (including longitude, latitude, and altitude), speed, and time parameters of objects on the Earth's surface and in near-Earth space.

[0123] The working process of the electric rescue vessel 1000 according to an embodiment of this application will be described below with reference to specific examples.

[0124] Please see Figures 12 to 14 The electric rescue vessel 1000 and the vessel with depleted power can interact via a cloud platform. When the depleted vessel stops sailing due to power loss, it sends a rescue signal to the rescue cloud platform via a rescue app. The electric rescue vessel 1000 then receives the rescue signal and sails to the rescue location. The electric rescue vessel 1000 approaches the stern of the depleted vessel and transmits the charging gun 32 to the depleted vessel's box-type power supply via the cable transmission system 30. The crew on the depleted vessel then grasp the charging gun 32 and plug it into the charging socket of the box-type power supply.

[0125] The electric rescue vessel 1000 communicates with the vessel with depleted power via a signal line embedded in the charging cable 31. After a successful handshake, the electric rescue vessel 1000 begins charging the depleted vessel to restore its power, and simultaneously, all power supply to the depleted vessel is restored. The electric rescue vessel 1000 follows closely behind the depleted vessel, navigating synchronously and automatically, with both vessels maintaining consistent GPS signals (i.e., sharing GPS signals). At this point, the electric rescue vessel 1000 enters intelligent navigation mode. Its visual recognition system and laser ranging system (or lidar system) locate and measure the distance to the depleted vessel. The electric rescue vessel 1000 activates its automatic navigation model, actively adjusting its various motion states to ensure that the position, speed, acceleration / deceleration, and direction of motion of both vessels remain consistent, allowing them to sail together towards the dock or shipyard.

[0126] In the above technical solution, during synchronous automatic navigation, the distance between the electric rescue vessel 1000 and the vessel with depleted power is controlled within a certain range, and the navigation trajectories of the two vessels are highly similar. This ensures that the charging gun 32 will not become loose or tight during navigation, thereby achieving the function of charging while sailing, and thus improving the timeliness of rescue.

[0127] In addition, the electric rescue vessel 1000 mentioned above has the advantages of low pollution and low cost. Moreover, in the process of rescuing and charging a vessel with a dead battery, it can not only restore the vessel's power, but also restore other power needs of the vessel, especially for some vessels transporting frozen fresh food that have lost power.

[0128] Please see Figure 15 For disabled fuel-powered vessels and disabled electric vessels, the towing assembly 60 of the electric rescue vessel 1000 can be used to tow them back to the dock or dry dock. In this case, the electric rescue vessel 1000 acts as a tugboat.

[0129] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0130] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
