The driving mechanism 303 is connected to the platform body 302, and the driving mechanism 303 is also connected to the drive control device 304 in a communication manner. For example, the drive mechanism 303 may be communicatively coupled to the drive control apparatus 304 by a wired or wireless means. The driving control device 304 may control the driving mechanism 303 to drive the platform body 302 to move up and down along the guide rail 3010 between the power exchanging platform 20 and the floating platform 10. The driving control device 304 may be disposed on the battery replacement platform 20.

The driving mechanism 303 may drive the platform body 302 to move up and down by a winch cable, a chain, a rack and pinion, a hydraulic lift, etc., and fig. 3a illustrates the driving mechanism 303 as a winch cable traction lifting mechanism.

In some embodiments, since the lower docking portion 104 of the floating platform 10 is lifted with the water level, the lower docking position of the platform body 302 is adjusted with the water level, so that the platform body 302 can be docked with the lower docking portion 104. The lift platform 30 further includes a first position sensing member 305 fixedly coupled to the floating platform 10. The first position sensing element 305 is communicatively coupled to the drive control device 304, for example, the first position sensing element 305 may be communicatively coupled to the drive control device 304 via a wired connection.

When the platform body 302 continues to move downwards to the second position, the first position sensing element 305 outputs the docking position state of the platform body 302 relative to the floating platform 10, and the driving control device 304 controls the driving mechanism 303 to stop moving the platform body 302, so that the platform body 302 is accurately docked with the low docking portion 104. The second position may be a position where the bottom of the platform body 302 is flush with the lower docking portion 104, and the docking position state of the platform body 302 with respect to the floating platform 10 may be a position state where the bottom of the platform body 302 is aligned with the lower docking portion 104.

Fig. 12 is a schematic flow chart of a method for replacing a ship battery according to an embodiment of the present disclosure. The ship battery replacement method can be applied to the battery replacement workstation 100 to realize rapid battery replacement of the ship 200. The battery replacing work station 100 comprises a floating platform 10, a battery replacing platform 20 and a lifting platform 30 capable of lifting between the battery replacing platform 20 and the floating platform 10, the floating platform 10 is provided with a ship berthing position 101, and a battery charging area 210 capable of placing and charging a battery with power shortage is arranged on the battery replacing platform 20. In this embodiment, the method for replacing a ship battery may include:

In some embodiments, the edge of the vessel docking station 101 may be provided with a proximity sensor by which sensing whether the vessel docking station 101 is docked with the vessel 200 is achieved. The main control device 2030 may enable receiving a first sensing signal of the vessel docking station 101 docking with the vessel 200 by communicating with the proximity sensor. The vessel 200 may establish a communication connection with the main control device 2030, and a vessel system onboard the vessel 200 may sense whether the battery is detached. When the power-deficient battery of the marine vessel 200 is discharged, the marine vessel 200 may transmit a second sensing signal to the main control device 2030, so that the main control device 2030 may receive the second sensing signal that the power-deficient battery of the marine vessel 200 is discharged. When the main control device 2030 receives a first sensing signal that the ship docking station 101 is docked with the ship 200 and a second sensing signal that the battery of the ship 200 with power shortage is discharged, indicating that the ship 200 has a power replacement requirement, the main control device 2030 can randomly select a fully charged battery from the battery charging area 210 to deliver to the ship 200. For example, each battery includes a roller, can move autonomously, and has a path planning module, a sensing module and a communication module, the sensing module can obtain a start position, an end position and ambient environment information of the battery, the path planning module can plan a global path for the battery to move from the start position to the end position according to the start position, the end position and the ambient environment information of the battery, and the battery can move autonomously according to the global path.

For example, when the main control device 2030 randomly selects a fully charged battery from the battery charging area 210, the dispatch management system may generate a dispatch task for the fully charged battery, where the dispatch task includes a task start point (the battery charging area 210) and a task end point (the ship berth 101 at which the ship 200 is berthed), and the battery may further communicate with the drive control device 304 to obtain operation information of the platform body 302, so that the battery may enter and exit the platform body 302, and further, the fully charged battery may be controlled to autonomously move from the battery charging area 210 to the ship berth 101 at which the ship 200 is berthed via the lifting platform 30.

The main control device 2030 may also control the onshore offshore unit 105 to move the fully charged battery of the ship docking station 101 to the ship 200 after the fully charged battery is moved from the battery charging area 210 to the ship docking station 101. For example, the offshore landing installation 105 is a hoisting mechanism by which the main control device 2030 moves a fully charged battery from the vessel docking station 101 to the vessel 200.

The fully charged battery may also be moved autonomously from the vessel docking station 101 to the vessel 200 by the offshore unit 105.

In step S102, the battery discharged from the ship 200 and having a power shortage is moved to the battery charging area 210 via the floating platform 10 and the elevating platform 30.

In some embodiments, the battery charging area 210 is provided with one or more charging devices 211, and when the power-deficient battery of the ship 200 is discharged, the power-deficient battery may be moved to the battery charging area 210 via the floating platform 10 and the lifting platform 30 to charge the power-deficient battery. In order to move the battery with insufficient power from the ship 200 to the battery charging area 210, the battery with insufficient power may be moved from the ship 200 to the ship docking station 101, then the battery with insufficient power at the ship docking station 101 may be moved to the lower docking portion 104, enter the platform body 302 through the lower docking portion 104, be transported to the upper docking portion 202, and then be moved from the upper docking portion 202 to the battery charging area 210.

In some embodiments, during the charging of the battery with insufficient power by the charging apparatus 211, the main control device 2030 may obtain the power of the battery with insufficient power in real time by communicating with the charging apparatus 211. When the main control device 2030 determines that the electric quantity of the battery with insufficient power is greater than the preset electric quantity, the main control device 2030 can control the charging device 211 to stop charging the battery with insufficient power, so that the charging safety of the battery is improved.

The power distribution device 204 can also be in communication connection with the main control device 2030, and when the main control device 2030 receives the third sensing signal, the main control device 2030 can control the power distribution device 204 to disconnect the power supply to the charging device 211, so that when it is monitored that the battery is on fire, the power is automatically cut off, and the charging safety of the battery is improved.

In some embodiments, the battery charging area 210 is further provided with a fire extinguishing device 212, the fire extinguishing device 212 being electrically connected with the main control device 2030. When the main control device 2030 receives the third sensing signal, the main control device 2030 may turn on the fire extinguishing apparatus 212 to extinguish the fire of the battery. For example, the fire extinguishing device 212 is a sprinkler, and the main control device 2030 may turn on a sprinkler head to spray water when receiving the third sensing signal, so as to extinguish the fire of the battery.

In some embodiments, the power exchanging platform 20 is further provided with a temperature sensor 206 and a ventilation device 207.

Fig. 13 is a schematic flow chart of a ship battery replacement method according to another embodiment of the present disclosure. The ship battery replacement method can be applied to the battery replacement workstation 100 to realize rapid battery replacement of the ship 200.

In this embodiment, the method for replacing a ship battery may include:

step S201, sensing whether the ship 200 is docked at the ship docking station 101.

In some embodiments, the edge of the vessel docking station 101 may be provided with a proximity sensor, by which sensing whether the vessel docking station 101 is docked with the vessel 200 may be achieved. The proximity sensor may be in communication with the main control device 2030 and may output a first sensing signal to the main control device 2030 when the proximity sensor senses that the vessel docking station 101 is docked with the vessel 200.

Step S202, when the ship 200 is detected to be parked at the ship berth 101, determining whether the ship 200 unloads a power-lack battery.

In some embodiments, when it is sensed by the proximity sensor that the ship docking station 101 docks with the ship 200, the main control apparatus 2030 may also determine whether the ship 200 unloads the battery due to power shortage by determining whether a second sensing signal transmitted by the ship 200 is received. For example, the vessel 200 may establish a communication connection with the main control device 2030, a vessel system onboard the vessel 200 may sense whether a battery is detached, and when a battery of the vessel 200 with a power shortage is detached, the vessel 200 may transmit a second sensing signal to the main control device 2030. When the main control device 2030 receives the second sensing signal transmitted from the ship 200, it is determined that the ship 200 unloads the battery of a power shortage.

In step S203, when the battery of the ship 200 with a power shortage is discharged, a fully charged battery is randomly selected from the battery charging area 210, and the selected battery is transported to the ship 200 via the lifting platform 30 and the floating platform 10.

In some embodiments, when it is determined that the battery of the ship 200 is discharged due to power shortage, which indicates that the ship 200 docked at the ship docking station 101 has a power swapping requirement, the main control device 2030 may output a prompt message that the ship docking station 101 needs to swap the fully charged battery through the human-computer interface of the central control center, and further may arrange for a worker to randomly select a fully charged battery from the battery charging area 210 to deliver to the ship 200.

The battery may be designed as a cart-type battery pack or a trailer-type battery pack, and the battery may include a roller, so that the battery may be conveniently and rapidly moved between the swapping platform 20 and the ship 200.

In some embodiments, the floating platform 10 is provided with an offshore loading installation 105, and the offshore loading installation 105 may be provided at the ship berth 101. After the fully charged battery is moved to the ship docking 101, the crew may manipulate the offshore unit 105 to move the fully charged battery of the ship docking 101 to the ship 200. For example, the offshore device 105 is a sling that a worker can manipulate to move a fully charged battery from the ship dock 101 to the ship 200.

The offshore unit 105 is a collapsible strap that can be bridged between the edge of the vessel berth 101 and the vessel 200. When the foldable access panels are docked between the edge of the vessel docking station 101 and the vessel 200, personnel can also move the batteries of the power deficit from the vessel 200 to the vessel docking station 101 via the foldable access panels.

In some embodiments, during the charging of the battery with insufficient power by the charging apparatus 211, the main control device 2030 may obtain the power of the battery with insufficient power in real time by communicating with the charging apparatus 211. When the main control device 2030 determines that the electric quantity of the battery with insufficient power is greater than the preset electric quantity, the main control device 2030 may control the charging device 211 to stop charging the battery with insufficient power, so as to improve the charging safety of the battery.

In some embodiments, a battery maintenance area 213 is further disposed on the battery replacement platform 20, and a battery with a power shortage detached from the ship 200 can be moved to the battery maintenance area 213 by an operator for detection, and when the battery with the power shortage is detected to be unnecessary for maintenance or service, the operator moves the battery with the power shortage from the battery maintenance area 213 to the battery charging area 210 for charging. The battery maintenance area 213 includes a battery detection device 2130 capable of detecting the state of a battery with a power loss, and a battery maintenance device 2131 capable of performing maintenance or repair on the battery with a power loss.
