Through the movement of the clamping claw 17, the battery pack is clamped and released.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, there are four clamping jaws 17, and the four clamping jaws 17 are distributed in a rectangular shape. The second transmission mechanism mainly includes a gear transmission mechanism and a screw nut mechanism. Two gear transmission mechanisms are provided, and the input end of one gear transmission mechanism is connected to the output end of the second motor 16. The two gear transmission mechanisms are connected through the first transmission shaft to achieve linkage.

The two nuts of the screw nut mechanism and the screw form a spiral transmission. The screw is provided with two sections of external threads with opposite rotation directions, which cooperate with the two nuts. After the second motor 16 is running, the power is transmitted to the two screw nut mechanisms through the synchronous movement of the two gear transmission mechanisms, and each screw nut mechanism drives the two pairs of clamping jaws 17 to move toward or away from each other. The battery pack is clamped by four common clamping mechanisms to ensure the reliability of the battery pack clamping.

When the drum 20 winds up the rope 19 , the rope 19 pulls the clamp 13 to move upward, so that the clamp 13 rises; when the drum 20 releases the rope 19 , the clamp 13 can move downward, so that the clamp 13 falls.

[0048] like Figure 4 and Figure 5 As shown, in this embodiment, four reels 20 are provided and are coaxially arranged in pairs.

The output end of each gear transmission mechanism is fixedly connected to the two coaxially arranged reels 20. Four ropes 19 are provided. The four ropes 19 are connected to the lifting plate 15 at four positions of the lifting plate 15 respectively. After the third motor 18 is running, the power is transmitted to the four reels 20 through the synchronous movement of the two gear transmission mechanisms. The four reels 20 rotate synchronously to achieve the rise and fall of the clamp 13.

[0049] like Figure 4 As shown, the transposition mechanism 12 is installed on the walking frame, and the transposition mechanism 12 is connected to the rotating frame 14. The transposition mechanism 12 is used to drive the rotating frame 14 to rotate around the set axis to a set angle (the set angle is 90 degrees), and the set axis is a vertical line.

[0050] like Figures 1 to 3 As shown, the carrying device includes a flatbed trailer and a traction seat 4 arranged on the flatbed trailer, the flatbed trailer includes a body 2 and a plurality of second running wheels 3 arranged on the body 2, and the battery bracket 1 is fixedly arranged on the body 2 of the flatbed trailer. A traction seat 4 is arranged at one end of the flatbed trailer, and the traction seat 4 is used to adapt to the tractor, and the tractor drives the carrying device to travel to realize the transfer of the battery pack.

A plurality of support mechanisms are provided, and all support mechanisms are distributed on opposite sides of the vehicle body 2. At least two support mechanisms are provided on the same side of the vehicle body 2, and all support mechanisms on the same side of the vehicle body 2 are arranged in sequence along the length direction of the vehicle body 2. After the flatbed trailer travels to the designated position, all support mechanisms simultaneously provide support to the flatbed trailer, provide additional support force, increase the stability and anti-overturning ability of the flatbed trailer, and ensure the stability and safety of the flatbed trailer during the ship's power replacement process.

[0052] As a preferred example, Figures 1 to 3 As shown, the support mechanism includes a leg 5, a second lifting actuator connected to the leg 5 and used to control the leg 5 to move up and down, a sliding seat, and a second telescopic actuator 6 connected to the sliding seat and used to control the sliding seat to move linearly in the horizontal direction. The moving direction of the sliding seat is parallel to the length direction of the flatbed trailer. The second lifting actuator is arranged on the sliding seat, and the second telescopic actuator 6 is arranged on the body 2 of the flatbed trailer. After the flatbed trailer travels to the designated position, the second telescopic actuator 6 pushes the sliding seat to move horizontally toward the outside of the flatbed trailer, and then the second lifting actuator pushes the leg 5 to move downward until the bottom surface of the leg 5 contacts the bottom surface below.

[0053] like Figures 1 to 3 As shown, in this embodiment, four support mechanisms are provided in total, and the four support mechanisms are distributed in a rectangular shape. The second telescopic actuator 6 and the second lifting actuator are both hydraulic cylinders, and the first telescopic actuator and the first lifting actuator 9 are also hydraulic cylinders.

[0054] In the above structure, the stability and safety of the vehicle during the battery replacement process are effectively improved through the combined design of the retractable legs 5 and the liftable box 8.

[0055] In the above structure, high-precision, automated grasping and handling of the battery pack is achieved through the innovative combination of the retractable truss robot 10 and the grasping mechanism.

[0056] like Figures 1 to 3As shown, a PCS (Power Conversion System) distribution cabinet is set on the body 2 of the carrier. The PCS distribution cabinet has built-in electrical connectors and distribution boxes to supply power to the entire battery swap system, and is equipped with a battery swap controller to realize battery charging and discharging control. The PCS distribution cabinet is connected to the vehicle power supply, provides power to the battery swap controller and gripping mechanism, etc., and is connected to the battery swap controller through a cable.

[0057] The battery-swapping and energy-replenishing vehicle for ships of the present invention also includes an on-board battery-swapping controller and a wireless module arranged on the vehicle body 2. The battery-swapping controller is connected to the controller in the PCS power distribution cabinet through a bus to control the entire battery-swapping process and communicate with the wireless module.

[0058] As the core control unit, the battery swap controller realizes the full automation of the battery swap process by integrating the control logic of battery identification, grabbing, hoisting, charging and other processes. During the battery swap process, the battery swap controller identifies the position and status of the battery to be replaced through sensors and controls the truss robot 10 to move to the appropriate position.

[0059] The wireless module supports 4G / 5G and WIFI signals for remote monitoring and data interaction. The introduction of the wireless module not only supports remote monitoring and data interaction, but also enhances the flexibility and maintainability of the system, facilitating troubleshooting and remote upgrades.

[0060] like Figure 6 and Figure 8 As shown, the method for replacing the battery of a ship using the above-mentioned ship battery replacement and energy replenishment vehicle includes the following steps:

[0061] S1. The ship's battery replacement and energy replenishment vehicle is in place;

[0062] S2, initiate battery replacement;

[0063] S3, box 8 rises;

[0064] S4, the position adjustment device extends out of the box 8;

[0065] S5, the grasping device moves to the grasping position;

[0066] S6. The grabbing device grabs the battery pack on the ship battery replacement and energy replenishment vehicle;

[0067] S7. The grabbing device transfers the grabbed battery pack to the ship.

[0068] In the above step S1, after the ship battery replacement and energy replenishment vehicle is in place, the second telescopic actuator 6 pushes the sliding seat to move horizontally toward the outside of the flatbed trailer, and then the second lifting actuator pushes the leg 5 to move downward until the bottom surface of the leg 5 contacts the bottom surface below. All supporting mechanisms simultaneously provide support for the flatbed trailer, provide additional support force, increase the stability and anti-overturning ability of the flatbed trailer, and ensure the stability and safety of the flatbed trailer during the ship battery replacement process.

[0069] In the above step S3, the first lifting actuator 9 extends to push the box body 8 to move upward until the box body 8 rises to a proper height.

[0070] In the above step S4, the first telescopic actuator extends, pushing the truss robot 10 to move toward the tail of the box 8, and extending the truss robot 10 to the outside of the tail of the box 8, and a part of the truss robot 10 is located above the power compartment of the ship.

[0071] In the above step S5 , the grasping device moves along the track 11 to above the battery pack to be grasped.

[0072] In the above step S6, after the grasping device moves to above the battery pack, the clamp 13 descends, grasps a battery pack, and then the clamp 13 rises.

[0073] In the above step S7, the grabbing device moves along the track 11 to the outside of the box 8, and then the clamp 13 descends to place the grabbed battery pack in the power compartment of the ship, and then the clamp 13 is separated from the battery pack, and finally the clamp 13 rises.

[0074] After repeating the above steps S5 to S7 multiple times, multiple battery packs can be replaced on the ship.

[0075] After the battery pack is replaced, the position adjustment device, the gripping device and the box 8 are reset. After the outriggers 5 are retracted, the ship's battery replacement and energy replenishment vehicle is ready to leave.

[0076] During the entire battery replacement process, the wireless module transmits data to the remote monitoring center in real time, supporting remote control and fault diagnosis. The support of the wireless module enables remote monitoring and data interaction, improving the intelligence level and maintainability of the system.

[0077] The battery replacement and energy replenishment vehicle for ships using the above structure has the following advantages:

[0078] 1. Improve battery replacement efficiency:

[0079] By integrating automated and mechanized battery replacement processes, such as automatic identification, precise positioning, rapid grabbing and lifting, the battery replacement time is significantly shortened and the battery replacement efficiency is improved.

[0080] 2. Enhanced security:

[0082] The sophisticated design and fine-tuning function of the grabbing device can ensure the stability of the battery box during grabbing, moving and installation, reducing potential damage to the battery and vehicles and ships.

[0083] 3. Improve operational convenience:

[0084] The entire battery replacement process is highly automated, reducing manual intervention, operation difficulty and labor intensity. The driver only needs to perform simple operations to complete the battery replacement without complex skills or knowledge.

[0085] The on-board battery replacement controller integrates functions such as battery identification, grabbing, lifting, and charging. The battery replacement process can be completed through one-click operation, improving the convenience of operation and user experience.

[0086] 4. Enhance system intelligence:

[0087] The introduction of wireless modules supports 4G / 5G and WIFI signals, realizes remote monitoring and data interaction, and enables the operators of battery swap stations to monitor the status and operation of battery swap equipment in real time, promptly discover and solve problems, and improve the intelligence and maintainability of the system.

[0088] The battery swap controller can intelligently adjust the battery swap strategy according to the battery status and ship needs, such as selecting the battery with the optimal charge capacity for replacement, further improving the intelligence level of the system.

[0089] 5. Promote energy utilization and environmental protection:

[0090] The intelligent rapid battery replacement system can manage battery resources more efficiently. Through centralized charging and battery replacement, it reduces the ship's dependence on fuel or traditional energy, and promotes the use of clean energy and energy conservation and emission reduction.

[0091] The battery swap mode also helps the cascade utilization and recycling of batteries, extending the battery life and reducing resource waste and environmental pollution.

[0092] 6. Improve user experience:
