[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the implementation manners of this application in detail in conjunction with the accompanying drawings.

[0031] Figure 1 A battery swapping workstation provided by an embodiment of this application is shown.

[0032] Please refer to Figure 1 , the battery swapping workstation 100 includes a floating platform 10, a battery swapping platform 20, and a lifting platform 30. The floating platform 10 floats on the water surface of the water area 400, and the floating platform 10 can float up and down with the rise and fall of the water level in the water area. The battery swapping platform 20 is erected on the shore 500 and is always located above the water area 400, maintaining a certain distance between the battery swapping platform 20 and the water surface of the water area 400, which can prevent the battery swapping platform 20 from being affected by the water level in the water area. The lifting platform 30 can move up and down between the battery swapping platform 20 and the floating platform 10, and the lifting platform 30 is used to transport batteries between the battery swapping platform 20 and the floating platform 10.

[0033] For example, as Figure 1As shown in the figure, the elevation of the floating platform 10 can rise and fall with the water level of the water area 400. A plurality of support columns 201 are provided at the bottom of the battery swapping platform 20. One end of each support column 201 at a high elevation position is fixedly connected to the battery swapping platform 20, and the other end of each support column 201 is embedded in the shore base 501. The support column 201 can be any columnar structure with high support strength such as a steel structure, a reinforced concrete structure, or a concrete structure. The shore base 501 can refer to the land or concrete structure located below the battery swapping platform 20, and the shore base 501 can be a part of the shore 500 or a part of the riverbed. The battery swapping platform 20 is provided with a battery charging area 210, and the battery charging area 210 is provided with a charging device 211 (such as Figure 5 shown) for charging the depleted battery. The number of the charging devices 211 can be set according to the actual charging requirements, and the present application does not limit this. The charging device 211 can be electrically connected to one or more charging interfaces, that is, one charging device 211 can charge one or more depleted batteries simultaneously.

[0034] Such as Figure 2 shown, the floating platform 10 is provided with at least one ship berth 101 for berthing the ship 200, and the ship 200 is a battery-powered ship. The ship berth 101 can receive the depleted battery from the berthed ship 200 or deliver the fully charged battery to the ship 200. The ship berth 101 can be strip-shaped, and the ship berths 101 located on the same side can be arranged side by side. The floating platform 10 can be arranged in a water area with relatively gentle water flow. The floating platform 10 is provided with a plurality of through holes 102, and positioning rods 103 can be arranged in the through holes 102. The positioning rods 103 can be used as guide rods for the lifting of the floating platform 10. The lower ends of the positioning rods 103 are used to be fixed to the shore base at a specified water area position, and the horizontal movement of the floating platform 10 is restricted by the positioning rods 103. The floating platform 10 can move up and down along the positioning rods 103 to meet the ship berthing requirements.

[0035] The battery charging area 210 can be used to place and charge the depleted battery received by the ship berth 101, or deliver the fully charged battery to the ship berth 101.

[0036] It can be understood that the ship 200 in this embodiment can be an electric bamboo raft. Electric bamboo rafts often need to travel in waters where the ebb and flow of the tide are very frequent, resulting in the elevation of the berthing point of the electric bamboo raft often changing frequently. Based on the conventional berthing method, the position of the ship 200 on the shore will change constantly, resulting in the distance between the battery replacement area and the ship berthing position always changing, which is not conducive to battery replacement.

[0037] In this embodiment, the floating platform 10 can rise and fall with the water level of the water area 400. Whether it is high tide or low tide, the ship 200 can always quickly dock at the ship docking position 101 of the floating platform 10, and the distance between the ship 200 and the battery replacement area on the battery replacement platform 20 can always remain unchanged. When the ship 200 unloads the discharged battery, the discharged battery can be transported to the floating platform 10. The discharged battery on the floating platform 10 can be transported to the lifting platform 30. The lifting platform 30 raises and transports the discharged battery to the battery replacement platform 20. The fully charged battery on the battery replacement platform 20 is transported to the lifting platform 30. The lifting platform 30 lowers the fully charged battery to the floating platform 10. The fully charged battery on the floating platform 10 is then transported to the ship 200, realizing the rapid battery replacement for the ship 200.

[0038] Of course, in other embodiments, the ship can also be a watercraft such as a passenger ship, merchant ship, cargo ship, yacht, or kayak, and the battery replacement workstation 100 can also be applied to water areas such as lakes, rivers, waterways, and seas where the water level is often in a changing state.

[0039] As Figure 3a shown, the lifting platform 30 includes support columns 301, a platform body 302, a driving mechanism 303, and a drive control device 304. The support columns 301 are fixed to the foundation at the bottom of the water area 400. The support columns 301 are provided with guide rails 3010. The platform body 302 is movably connected to the support columns 301. The platform body 302 can move up and down between the battery replacement platform 20 and the floating platform 10 along the guide rails 3010. The driving mechanism 303 is connected to the platform body 302, and the driving mechanism 303 is also communicatively connected to the drive control device 304. For example, the driving mechanism 303 can be communicatively connected to the drive control device 304 by wire or wirelessly. The drive control device 304 can control the driving mechanism 303 to drive the platform body 302 to move up and down between the battery replacement platform 20 and the floating platform 10 along the guide rails 3010. The drive control device 304 can be arranged on the battery replacement platform 20.

[0040] The lifting method of the driving mechanism 303 driving the platform body 302 can be winch wire rope traction lifting, chain type lifting, rack and pinion type lifting, hydraulic lifting, etc. Figure 3a Taking the driving mechanism 303 as a winch wire rope traction lifting mechanism as an example for illustration.

[0041] In some embodiments, the driving mechanism 303 includes a power mechanism 3030 and a traction mechanism 3031 connected to the power mechanism 3030. The traction mechanism 3031 is connected to the platform body 302. The power mechanism 3030 is used to drive the traction mechanism 3031 to traction the platform body 302 to move up and down along the guide rails 3010.

[0042] As a possible implementation manner, as Figure 3bAs shown in the figure, the power mechanism 3030 is a traction machine. The power mechanism 3030 includes a motor 3034, a traction wheel 3035, and a guide wheel 3036. The traction mechanism 3031 may include a wire rope 3037 and a counterweight device 3038. One end of the wire rope 3037 is sequentially connected to the platform body 302 after passing through the guide wheel 3036 and the traction wheel 3035, and the other end is connected to the counterweight device 3038. When the motor 3034 rotates, it drives the traction wheel 3035 to rotate, driving the wire rope 3037 to drag the platform body 302 and the counterweight device 3038 to move relatively. When the platform body 302 rises, the counterweight device descends; when the counterweight device rises, the platform body 302 descends.

[0043] In some embodiments, as Figure 3a shown, in order to prevent the platform body 302 from running at an excessive speed or to protect against the breakage of the wire rope, the drive mechanism 303 further includes a speed sensor 3032 and a brake 3033. Both the speed sensor 3032 and the brake 3033 are communicatively connected to the drive control device 304. The speed sensor 3032 is used to obtain the running speed of the platform body 302 and send the running speed to the drive control device 304. The drive control device 304 is further used to control the brake 3033 to restrict the movement of the platform body 302 when it determines that the running speed of the platform body 302 exceeds the set speed. The set speed can be set according to the actual operating requirements of the lifting platform 30, and the present application does not make any limitations in this regard.

[0044] The speed sensor 3032 can be disposed on the platform body 302 or the power mechanism 3030, and can sense the lifting and lowering running speed of the platform body 302 relative to the battery swapping platform 20. The brake 3033 is fixedly connected to the platform body 302 and is also movably connected to the guide rail 3010. When the drive control device 304 determines that the lifting and lowering running speed of the platform body 302 relative to the battery swapping platform 20 exceeds the set speed, it indicates that the platform body 302 is operating abnormally. The drive control device 304 controls the brake 3033 to firmly fix the platform body 302 on the guide rail 3010, thereby restricting the movement of the platform body 302 relative to the guide rail 3010. The number of brakes 3033 can be equal to the number of guide rails 3010, that is, one brake 3033 is correspondingly provided on each guide rail 3010, so as to enable the brake 3033 to effectively fix the platform body 302 on the guide rail 3010.

[0045] In some embodiments, the floating platform 10 is provided with a low-level docking portion 104 that docks with one end of the support column 301 at a low altitude position, and the battery swapping platform 20 is provided with a high-level docking portion 202 that docks with the other end of the support column 301. The platform body 302 can be respectively docked with the low-level docking portion 104 and the high-level docking portion 202, so that the platform body 302 can transport batteries between the battery swapping platform 20 and the floating platform 10.

[0046] In some embodiments, since the lower docking portion 104 of the floating platform 10 rises and falls with the water level of the water area, that is, the downward docking position of the platform body 302 also needs to be adjusted with the rise and fall of the water level of the water area so that the platform body 302 can be docked with the lower docking portion 104. The lifting platform 30 further includes a first position sensing member 305 fixedly connected to the floating platform 10. The first position sensing member 305 is communicatively connected to the drive control device 304. For example, the first position sensing member 305 can be communicatively connected to the drive control device 304 by a wired manner. The first position sensing member 305 is used to sense the distance between the platform body 302 and the floating platform 10 and output the position state of the platform body 302 relative to the floating platform 10 to the drive control device 304. The drive control device 304 can control the operation of the platform body 302 according to the position state output by the first position sensing member 305. For example, the drive control device 304 can control the platform body 302 to decelerate according to the position state output by the first position sensing member 305, and when the platform body 302 decelerates to a stop, it is docked with the lower docking portion 104. Since the first position sensing member 305 is fixedly connected to the floating platform 10, the first position sensing member 305 can rise and fall with the rise and fall of the floating platform 10, so that in the case where the lower docking portion 104 of the floating platform 10 rises and falls with the water level of the water area, the drive control device 304 can still control the platform body 302 to accurately dock with the lower docking portion 104 according to the position state output by the first position sensing member 305.

[0047] In some embodiments, the first position sensing member 305 is used to sense the approaching distance between the platform body 302 and the floating platform 10 and output the approaching position state of the platform body 302 relative to the floating platform 10. The drive control device 304 is used to control the platform body 302 to decelerate according to the approaching position state sensed by the first position sensing member 305, so as to control the platform body 302 to decelerate when it descends to a certain specified position, so that the platform body 302 can be docked with the lower docking portion 104.

[0048] In some embodiments, the first position sensing member 305 is further used to sense the docking distance between the platform body 302 and the floating platform 10 and output the docking position state. The drive control device 304 is used to control the platform body 302 to stop according to the docking position state sensed by the first position sensing member 305, so as to control the platform body 302 to stop moving when it descends to a certain specified position, so that the platform body 302 can be docked with the lower docking portion 104.

[0049] For example, a fully charged battery on the battery swapping platform 20 is transported to the lifting platform 30. The lifting platform 30 lowers the fully charged battery to the floating platform 10. The drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move downward along the guide rail 3010. When the platform body 302 moves downward to the first position, the first position sensor 305 outputs the proximity position state of the platform body 302 relative to the floating platform 10. The drive control device 304 decelerates the platform body 302 by controlling the drive mechanism 303. The first position can refer to the installation position of the first position sensor 305 or a position at the same altitude as the first position sensor 305. The proximity position state of the platform body 302 relative to the floating platform 10 can refer to the position state where the distance between the bottom of the platform body 302 and the low docking part 104 is the first preset distance. When the platform body 302 continues to move downward to the second position, the first position sensor 305 outputs the docking position state of the platform body 302 relative to the floating platform 10. The drive control device 304 stops the movement of the platform body 302 by controlling the drive mechanism 303, so as to accurately dock the platform body 302 with the low docking part 104. The second position can refer to the position where the bottom of the platform body 302 is flush with the low docking part 104. The docking position state of the platform body 302 relative to the floating platform 10 can refer to the position state where the bottom of the platform body 302 is aligned with the low docking part 104.

[0050] In some embodiments, the lifting platform 30 further includes a second position sensor 306 fixedly connected to the support column 301. The second position sensor 306 is communicatively connected to the drive control device 304. For example, the second position sensor 306 can be communicatively connected to the drive control device 304 by wire or wirelessly. The second position sensor 306 is used to sense the distance between the platform body 302 and the high docking part 202 of the battery swapping platform 20, and output the position state of the platform body 302 relative to the high docking part 202 to the drive control device 304. The drive control device 304 can control the operation of the platform body 302 according to the position state output by the second position sensor 306, so that the platform body 302 can accurately dock with the high docking part 202 of the battery swapping platform 20.

[0051] In some embodiments, the second position sensor 306 is used to sense the proximity distance between the platform body 302 and the high docking part 202, and output the proximity position state of the platform body 302 relative to the high docking part 202. The drive control device 304 is used to decelerate the platform body 302 according to the proximity position state sensed by the second position sensor 306, so as to control the platform body 302 to decelerate when moving upward to a certain specified position, so that the platform body 302 can dock with the high docking part 202.

[0052] In some embodiments, the second position sensor 306 is further configured to sense the docking distance between the platform body 302 and the high-level docking part 202, and output the docking position state. The drive control device 304 is configured to control the platform body 302 to stop according to the docking position state sensed by the second position sensor 306, so as to control the platform body 302 to stop moving when it moves upward to a certain specified position, so that the platform body 302 is docked with the high-level docking part 202.

[0053] For example, a discharged battery on the floating platform 10 is transported to the lifting platform 30, and the lifting platform 30 transports the discharged battery upward to the battery swapping platform 20. The drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move upward along the guide rail 3010. When the platform body 302 moves upward to the third position, the second position sensor 306 outputs the approaching position state of the platform body 302 relative to the high-level docking part 202. The drive control device 304 controls the drive mechanism 303 to decelerate the platform body 302. The third position may refer to the installation position of the second position sensor 306 or a position at the same altitude as the second position sensor 306. The approaching position state of the platform body 302 relative to the high-level docking part 202 may refer to a position state where the distance between the bottom of the platform body 302 and the high-level docking part 202 is a second preset distance. When the platform body 302 continues to move upward to the fourth position, the first position sensor 305 outputs the docking position state of the platform body 302 relative to the high-level docking part 202. The drive control device 304 controls the drive mechanism 303 to stop the platform body 302 from moving, so as to realize the accurate docking of the platform body 302 with the high-level docking part 202. The fourth position may refer to a position where the bottom of the platform body 302 is flush with the high-level docking part 202. The docking position state of the platform body 302 relative to the high-level docking part 202 may refer to a position state where the bottom of the platform body 302 is aligned with the high-level docking part 202.

[0054] Such as Figure 4aAs shown, the first position sensor 305 includes a connecting rod 3050, a first sensor mounting member 3051, a first sensor 3052, and a second sensor 3053. One end of the connecting rod 3050 is fixedly connected to the first sensor mounting member 3051, and the other end of the connecting rod 3050 is fixedly connected to the floating platform 10. The first sensor 3052 is fixedly arranged on the first sensor mounting member 3051, and the first sensor 3052 is used to sense the approaching distance between the platform body 302 and the floating platform 10. The second sensor 3053 is fixedly arranged on the first sensor mounting member 3051, and the second sensor 3053 is used to sense the docking distance between the platform body 302 and the floating platform 10. The second sensor 3053 can be located below the first sensor 3052. The first sensor mounting member 3051 is movably connected to the support column 301, and the first sensor mounting member 3051 can move up and down along the support column 301 as the floating platform 10 rises and falls, that is, the first sensor 3052 and the second sensor 3053 can rise and fall as the floating platform 10 rises and falls. In the case where the low docking portion 104 of the floating platform 10 rises and falls with the water level of the water area, the drive control device 304 can still control the platform body 302 to accurately dock with the low docking portion 104 based on the sensing signals of the first sensor 3052 and the second sensor 3053. In other embodiments, the second sensor 3053 can also be omitted. In this case, the drive control device 304 is used to control the platform body 302 to decelerate until it stops according to the approaching position state sensed by the first sensor 305 (the approaching position state of the platform body 302 relative to the low docking portion 104), so that the platform body 302 docks with the low docking portion 104.

[0055] In some embodiments, a sliding square tube 3011 is provided on the support column 301, and the first sensor mounting member 3051 is sleeved on the sliding square tube 3011. Further, the first sensor mounting member 3051 can move up and down along the sliding square tube 3011 as the floating platform 10 rises and falls.

[0056] The second position sensor 306 includes a second sensor mount 3060, a third sensor 3061, and a fourth sensor 3062. The second sensor mount 3060 is fixedly connected to the support column 301, and the third sensor 3061 is fixedly disposed on the second sensor mount 3060. The third sensor 3061 is used to sense the proximity distance between the platform body 302 and the high-level docking portion 202. The fourth sensor 3062 is fixedly disposed on the second sensor mount 3060, and the fourth sensor 3062 is used to sense the docking distance between the platform body 302 and the high-level docking portion 202. The third sensor 3061 may be located below the fourth sensor 3062. In other embodiments, the fourth sensor 3062 may also be omitted. In this case, the drive control device 304 is used to control the platform body 302 to decelerate until it stops according to the proximity position state sensed by the third sensor 3061 (the proximity position state of the platform body 302 relative to the high-level docking portion 202), so as to realize the docking of the platform body 302 and the high-level docking portion 202.

[0057] In some embodiments, the platform body 302 is provided with a platform support plate 3020 and a limiting member 3021 that opens and closes relative to the platform support plate 3020. The limiting member 3021 is slidably engaged with the support column 301. When the limiting member 3021 is closed relative to the platform support plate 3020, it restricts the battery from being removed from or inserted into the platform support plate 3020; when the limiting member 3021 is opened relative to the platform support plate 3020, it allows the battery to be removed from or inserted into the platform support plate 3020.

[0058] As a possible implementation manner, the platform support plate 3020 is provided with a door guide rail 3022, and the limiting member 3021 is provided with a pull door 3023 that can move up and down along the door guide rail 3022. When the pull door 3023 is closed relative to the platform support plate 3020, it restricts the battery from being removed from or inserted into the platform support plate 3020; when the pull door 3023 is opened relative to the platform support plate 3020, it allows the battery to be removed from or inserted into the platform support plate 3020.

[0059] In some embodiments, the platform support plate 3020 may be provided with two door guide rails 3022, and the limiting member 3021 is provided with two pull doors 3023 that can move up and down along the two door guide rails 3022 respectively. The two pull doors 3023 are oppositely arranged. When the platform body 302 is docked with the high-level docking portion 202, the staff on the battery swapping platform 20 can open one side of the pull door 3023 to remove or insert the battery into the platform support plate 3020. When the platform body 302 is docked with the low-level docking portion 104, the staff on the floating platform 10 can open the other side of the pull door 3023 to remove or insert the battery into the platform support plate 3020.

[0060] In some embodiments, the platform body 302 is further provided with a proximity sensor 3024 fixed to the platform support plate 3020. The proximity sensor 3024 is communicatively connected to the drive control device 304. For example, the proximity sensor 3024 is communicatively connected to the drive control device 304 by a wired or wireless manner. The proximity sensor 3024 is configured to sense the proximity distance of the pull door 3023 relative to the platform support plate 3020 and output the opening and closing state of the pull door 3023 relative to the platform support plate 3020. The drive control device 304 is further configured to control the operation of the platform body 302 according to the opening and closing state of the pull door 3023 sensed by the proximity sensor 3024. For example, when the proximity sensor 3024 senses that the pull door 3023 is in a closed state relative to the platform support plate 3020, the drive control device 304 can control the operation of the platform body 302. When the proximity sensor 3024 senses that the pull door 3023 is in an open state or not closed in place relative to the platform support plate 3020, the drive control device 304 controls the platform body 302 to pause operation, which can prevent the staff from entering the platform support plate 3020 during the operation of the platform body 302, or removing or inserting the battery into or out of the platform support plate 3020 during the operation of the platform body 302, thus avoiding safety accidents.

[0061] In some embodiments, as Figure 4b shown, the platform support plate 3020 may further be provided with a weight alarm device 3025. The weight alarm device 3025 may include a weight detection module 3026 and an alarm module 3027. The weight detection module 3026 is electrically connected to the alarm module 3027. The weight detection module 3026 may include a pressure sensor and a controller. The alarm module 3027 may include a buzzer. The controller may control the buzzer to sound or not sound according to the sensing data of the pressure sensor. The alarm module 3027 may also be disposed on the inner wall of the platform body 302. The weight detection device 3025 is configured to detect the weight of an object on the platform support plate 3020 and may output a first warning message when it detects that the weight of the object on the platform support plate 3020 exceeds a preset weight. The weight alarm device 3025 may also be communicatively connected to the drive control device 304. The drive control device 304 is further configured to control the drive mechanism 303 to pause driving the platform body 302 to move when the weight of the object on the platform support plate 3020 exceeds the preset weight, so as to avoid safety accidents caused by overloading of the lifting platform 30. The first warning message may be a sound / light warning message. The preset weight may be set according to the weight that the platform support plate 3020 can bear and the driving force of the drive mechanism 303.

[0062] For example, when the weight detection module 3026 detects that the weight of an object on the platform support plate 3020 exceeds a preset weight, the alarm module 3027 issues an audible alarm message, and the drive control device 304 controls the drive mechanism 303 to suspend driving the platform body 302. When the weight of the object on the platform support plate 3020 returns to less than the preset weight, the alarm module 3027 stops issuing the audible alarm message, and the drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move.

[0063] In some embodiments, as Figure 4c shown, the lifting platform 30 may further include a lift switch 307 communicatively connected to the drive control device 304. The drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move up and down along the guide rail 3010 or stop moving according to the control instruction of the lift switch 307. For example, the lift switch 307 is a push-button switch, and the interior of the push-button switch includes a light-emitting diode for outputting a switch-pressing prompt. When a staff member presses the push-button switch, the light-emitting diode is lit.

[0064] In some embodiments, the lift switch 307 may include an up switch 3071, a down switch 3072, and an emergency stop switch 3073 arranged in sequence. The up switch 3071 is used to output a control instruction for controlling the platform body 302 to move upward. The drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move from the low docking part 104 to the high docking part 202 along the guide rail 3010 according to the control instruction of the up switch 3071. The down switch 3072 is used to output a control instruction for controlling the platform body 302 to move downward. The drive control device 304 can control the drive mechanism 303 to drive the platform body 302 to move from the high docking part 202 to the low docking part 104 along the guide rail 3010 according to the control instruction of the down switch 3072. The emergency stop switch 3073 is used to output a control instruction for controlling the platform body 302 to stop urgently. The drive control device 304 can control the drive mechanism 303 to stop the platform body 302 according to the control instruction of the emergency stop switch 3073.

[0065] In some embodiments, the staff can also communicate with the drive control device 304 through a device carried with them (such as a mobile phone) to remotely control the drive mechanism 303 to drive the platform body 302 to move up and down or stop moving along the guide rail 3010. For example, the drive control device 304 can be configured to enable or disable the remote control function. When the remote control function is enabled, the mobile phone is allowed to send control instructions to the drive control device 304 to remotely control the operation of the platform body 302. To avoid multiple devices simultaneously requesting to control the operation of the platform body 302, the drive control device 304 can be preset with a pairing and locking rule. After a certain device establishes a communication connection with the drive control device 304, other devices cannot establish a communication connection with the drive control device 304 anymore.

[0066] As Figure 5 shown, the battery swapping platform 20 is further provided with a platform status monitoring device 203. The platform status monitoring device 203 can include a main control device 2030 and a central control display screen 2031. The central control display screen 2031 can include a display panel and a speaker. The main control device 2030 can be a device such as a computer or a server. The speaker can also be independent of the central control display screen 2031. The main control device 2030 controls the display content of the central control display screen 2031 and controls the speaker to emit sound respectively. The central control display screen 2031 is communicatively connected to the main control device 2030. For example, the central control display screen 2031 communicates with the main control device 2030 in a wired manner. The main control device 2030 can control the central control display screen 2031 to display information related to the battery swapping platform 20, information related to the lifting platform 30, information related to the battery, etc. For example, the central control display screen 2031 can display the ventilation information, temperature information, alarm information of the battery swapping platform 20, the charging status of the battery, the operation information of the lifting platform 30, etc.

[0067] In some embodiments, the main control device 2030 is communicatively connected to the charging device 211. The connection method can be a wired connection or a wireless connection. The main control device 2030 is used to obtain the working status information of the charging device 211 and visually display the working status information of the charging device 211 by controlling the central control display screen 2031. The working status information of the charging device 211 can include whether a battery is connected (for example, being connected with a battery is an occupied state, and not being connected with a battery is an idle state) and the charging status of the battery (for example, fully charged, charging).

[0068] For example, the main control device 2030 can control the central control display screen 2031 to display the working status of each charging device 211 in the form of a graph, facilitating the staff to understand the usage of each charging device 211. A status light can also be set on the charging device 211, and the charging device 211 can control the status light to display different colors according to the charging status of the battery. For example, the status light shows red during charging and green when fully charged, further facilitating the staff to understand the charging situation of the battery and enabling the staff to promptly replace the fully charged battery with a discharged battery for charging.

[0069] In some embodiments, the charging device 211 can also obtain the charging status information of the discharged battery and transmit the charging status information to the main control device 2030. The charging status information can include information such as battery power, charging current, and charging voltage. The main control device 2030 is also used to determine whether the power of the discharged battery is greater than a preset power, and the preset power can be set according to the actual parameter performance of the battery. When the power of the discharged battery is greater than the preset power, the main control device 2030 controls the charging device 211 to stop charging the discharged battery, realizing automatic disconnection of charging when the charging amount of the discharged battery reaches a certain power to ensure battery safety. For example, when the state of charge (SOC) of the discharged battery is greater than 95%, the main control device 2030 controls the charging device 211 to stop charging the discharged battery.

[0070] The main control device 2030 is also used to determine whether the charging current (charging voltage) of the discharged battery is greater than a preset current (preset voltage), and the preset current (preset voltage) can be set according to the actual parameter performance of the battery. When the charging current (charging voltage) of the discharged battery is greater than the preset current (preset voltage), the main control device 2030 can determine that the discharged battery is an abnormally charged battery, and the main control device 2030 controls the charging device 211 to stop charging the discharged battery to ensure battery charging safety. The main control device 2030 can also control the central control display screen 2031 to output a first alarm message to prompt the staff to handle the abnormally charged battery. The first alarm message can include a text warning message and the number information of the charging device 211 connected to the discharged battery, so as to facilitate the staff to quickly locate the abnormally charged battery.

[0071] In some embodiments, the battery swapping platform 20 further includes a power distribution device 204. The power distribution device 204 is electrically connected to an external power grid (such as the mains power). The power distribution device 204 is also electrically connected to the charging device 211, the drive control device 304, the drive mechanism 303, and the platform status monitoring device 203. The power distribution device 204 is used to supply power to the charging device 211, the drive control device 304, the drive mechanism 303, and the platform status monitoring device 203. The power distribution device 204 can also detect whether there are power failures in electrical equipment such as the charging device 211, the drive control device 304, and the platform status monitoring device 203. When a power failure occurs in a certain electrical equipment, the power distribution device 204 can cut off the power supply to it in a timely manner. The power failure can include overcurrent faults, short - circuit faults, etc. For example, when the power distribution device 204 detects a power failure in the charging device 211, the power distribution device 204 disconnects the power supply to the charging device 211. When the power distribution device 204 detects a power failure in the drive control device 304, the power distribution device 204 disconnects the power supply to the drive control device 304.

[0072] In some embodiments, the power distribution device 204 can also be communicatively connected to the platform status monitoring device 203 by wired or wireless means. The power distribution device 204 can also transmit the detected power failure information to the platform status monitoring device 203. The platform status monitoring device 203 can output a power failure alarm according to the power failure information. The power failure alarm can include alarm information such as sound and / or text. For example, when the power distribution device 204 detects a power failure in the charging device 211, the power distribution device 204 disconnects the power supply to the charging device 211 and transmits the power failure information of the charging device 211 to the platform status monitoring device 203. The platform status monitoring device 203 can output an alarm information indicating that there is a power failure in the charging device 211.

[0073] In some embodiments, the drive control device 304 can also be communicatively connected to the platform status monitoring device 203 by wired or wireless means. The drive control device 304 is also used to obtain the operating state of the drive mechanism 303 and send the operating state information of the drive mechanism 303 to the platform status monitoring device 203. The platform status monitoring device 203 is also used to visually display the operating state information of the drive mechanism 303, or output a lifting abnormality alarm when it determines that the drive mechanism 303 is operating abnormally based on the operating state information of the drive mechanism 303. For example, it can be displayed on the central control display screen 2031 whether the drive mechanism 303 is operating normally or abnormally. When the drive mechanism 303 cannot drive the platform body 302 to lift or lower normally, the main control device 2030 can control the central control display screen 2031 to output a lifting abnormality alarm.

[0074] In some embodiments, the battery swapping platform 20 is further provided with a fire monitoring device 205. The fire monitoring device 205 is used to monitor whether the batteries located in the battery charging area 210 catch fire, and when a battery on fire is detected, output a battery fire alarm. The battery fire alarm can be an audible and / or visual alarm to remind the staff of the battery swapping station to handle it quickly. For example, the fire monitoring device 205 includes a smoke sensor and an audible and visual alarm. The battery charging area 210 can be a room on the platform 20, in which at least one charging device 211 is arranged. The smoke sensor can be set on the roof, and the audible and visual alarm can be set on the wall.

[0075] In some embodiments, the fire monitoring device 205 can also be communicatively connected to the platform status monitoring device 203. The connection method can be wired or wireless. The fire monitoring device 205 can transmit the fire monitoring result to the platform status monitoring device 203. The platform status monitoring device 203 is further used to output a battery fire alarm when it determines that there is a battery on fire in the battery charging area 210 based on the monitoring result. For example, the text / voice alarm information of the battery fire can be output through the central control display screen 2031 in the platform status monitoring device 203.

[0076] In some embodiments, a fire extinguishing device 212 is further arranged in the battery charging area 210. The fire extinguishing device 212 is electrically connected to the fire monitoring device 205. When the fire monitoring device 205 detects a battery on fire, the fire extinguishing device 212 can be automatically turned on to release the fire extinguishing agent to extinguish the fire of the battery on fire. For example, the battery charging area 210 is a room on the platform 20, the fire extinguishing device 212 is a sprinkler device, the sprinkler heads of the fire extinguishing device 212 are set on the roof. When the fire monitoring device 205 detects a battery on fire, it outputs a fire sensing signal to the fire extinguishing device 212, and the fire extinguishing device 212 turns on the sprinkler heads to spray water according to the fire sensing signal to extinguish the fire of the battery on fire.

[0077] In some embodiments, the fire extinguishing device 212 can also be communicatively connected to the main control device 2030. The connection method can be wired or wireless. When the fire monitoring device 205 detects a battery on fire, the main control device 2030 controls the fire extinguishing device 212 to turn on to extinguish the fire of the battery on fire. The fire extinguishing device 212 can also include fire extinguishers, which can be placed on the floor of the room or on the shelves in the room, facilitating the staff of the battery swapping station to manually turn on the fire extinguishers to extinguish the fire of the battery on fire.

[0078] In some embodiments, the battery swapping platform 20 is further provided with a temperature sensor 206, a ventilation device 207 and a ventilation control device 208. The temperature sensor 206 and the ventilation device 207 are communicatively connected to the ventilation control device 208. The temperature sensor 206, the ventilation device 207 and the ventilation control device 208 are electrically connected to the power distribution device 204, and the power distribution device 204 is used to supply power to the temperature sensor 206, the ventilation device 207 and the ventilation control device 208. Since battery charging generates heat, and the charging efficiency and charging safety of the battery have a certain relationship with the ambient temperature, the temperature sensor 206 and the ventilation device 207 can be arranged in the battery charging area 210. The temperature sensor 206 is used to sense the ambient temperature of the battery charging area 210, and the ventilation control device 208 is used to control the operating state of the ventilation device 207 according to the ambient temperature sensed by the temperature sensor 206, so as to adjust the ambient temperature of the battery charging area 210 and improve the charging efficiency and charging safety of the battery. The ventilation device 207 can be devices such as a fan, an air conditioner, etc. Controlling the operating state of the ventilation device 207 can mean whether to turn on the ventilation device 207, and adjust the rotation speed, temperature, etc. of the ventilation device 207.

[0079] In some embodiments, the ventilation control device 208 can also be communicatively connected to the platform status monitoring device 203 by wired or wireless means. The ventilation control device 208 is further used to obtain the operating state of the ventilation device 207 and transmit the operating state information of the ventilation device 207 to the platform status monitoring device 203. The platform status monitoring device 203 is used to visually display the operating state information of the ventilation device 207, or output a ventilation abnormality alarm when it is determined that the ventilation device 207 is operating abnormally based on the operating state information. For example, information such as the rotation speed of the fan and the temperature of the air conditioner can be displayed on the central control display screen 2031. When the ventilation device 207 cannot be turned on or off, or the operating parameters of the ventilation device 207 cannot be adjusted, the main control device 2030 can control the central control display screen 2031 to output a ventilation abnormality alarm. In other embodiments, the ventilation control device 208 can also be omitted. The temperature sensor 206 and the ventilation device 207 are communicatively connected to the main control device, and the connection method can be wired connection or wireless connection. The main control device can control the operating state of the ventilation device 207 according to the ambient temperature sensed by the temperature sensor 206.

[0080] In some embodiments, the battery swapping platform 20 is further provided with a battery maintenance area 213, and a battery detection device 2130 is arranged in the battery maintenance area 213. The battery detection device 2130 can be used to detect the status of the battery located in the battery maintenance area 213 and output the detection result. The detection result may include at least one of whether the battery has a fault, the type of the fault that occurs, and battery maintenance suggestions (such as adding electrolyte). For example, the battery maintenance area 213 is another room on the platform 20, and the battery detection device 2130 is arranged in this room. The discharged battery unloaded from the ship can be moved to the battery maintenance area 213 for status detection, or when the charging device 211 charges the discharged battery and detects abnormal battery charging, the staff can move the battery with abnormal charging to the battery maintenance area 213 for status detection.

[0081] In some embodiments, the battery maintenance area 213 is further provided with a battery maintenance device 2131. The battery maintenance device 2131 can repair or maintain the battery according to the detection result of the battery detection device 2130. For example, the battery maintenance device 2131 includes a battery repair device and a battery maintenance device. When the battery detection device 2130 detects that the battery has a fault, the battery repair device can repair the battery according to the fault detection result; when the battery detection device 2130 detects that the battery needs to add electrolyte, the battery maintenance device can add electrolyte to the battery. The battery maintenance device 2131 can also be communicatively connected to the battery detection device 2130 to obtain the detection result of the battery detection device 2130 for detecting the battery.

[0082] In some embodiments, the battery swapping platform 20 is further provided with a battery conveying device 209. One end of the battery conveying device 209 is arranged at a first position of the battery swapping platform 20, and the other end is arranged at a second position of the battery swapping platform 20. The battery conveying device 209 is used to convey the battery between the first position and the second position. For example, the first position is located in the battery charging area 210, and the second position is adjacent to the high-level docking part 202. The battery conveying device 209 is a conveying track, and the battery can be quickly transported between the battery charging area 210 and the lifting platform 30 through the conveying track, shortening the battery charging time or the battery swapping time.

[0083] As Figure 6As shown in the figure, in order to quickly replace the battery 300 of the ship 200 and reduce the operation time of ship battery replacement, the battery 300 can be designed as a trolley-type battery pack or a trailer-type battery pack. The battery 300 can include rollers 3001, steering wheels 3002, a battery body 3003, a push handle 3004, and a connector 3005. The movement and steering of the battery 300 are realized through the rollers 3001 and the steering wheels 3002, so that the battery can be conveniently and quickly moved between the platform and the ship. The battery 300 can also be quickly plugged and unplugged through the connector 3005, enabling the quick connection and disconnection between the battery 300 and the charging device 211 or the ship 200, so as to reduce the operation time of battery replacement and charging.

[0084] In some embodiments, as Figure 7a shown, a shore landing and departure device 105 is further provided on the floating platform 10. The shore landing and departure device 105 is movably arranged at the edge of the floating platform 10. When the shore landing and departure device 105 is in the first state, the shore landing and departure device 105 is lapped between the ship 200 and the floating platform 10 for the battery to travel offshore or ashore between the edge of the floating platform 10 and the ship 200; when the shore landing and departure device 105 is in the second state, the shore landing and departure device 105 disconnects the connection between the ship 200 and the floating platform 10 to prevent the battery from traveling offshore or ashore between the edge of the floating platform 10 and the ship 200. For example, the shore landing and departure device 105 is a foldable boarding plank, which includes an unfolded state and a folded state. When the foldable boarding plank is in the unfolded state, the foldable boarding plank is lapped between the ship 200 and the floating platform 10. When the foldable boarding plank is in the folded state, the connection between the ship 200 and the floating platform 10 is disconnected. The foldable boarding plank can be a manually foldable boarding plank, a power-driven foldable boarding plank, or a hydraulic-driven foldable boarding plank.

[0085] In some embodiments, the floating platform 10 is further provided with a proximity sensing device 106 and a shore landing and departure control device 107. The proximity sensing device 106 is fixedly arranged at the edge of the floating platform 10 or the edge of the ship docking position 101. The shore landing and departure device 105 and the proximity sensing device 106 are communicatively connected to the shore landing and departure control device 107. When the proximity sensing device 106 senses that the distance between the ship 200 and the floating platform 10 (or the ship docking position 101) is within a preset distance and the duration is greater than a preset time, it indicates that the ship 200 is docked at the floating platform 10. The shore landing and departure control device 107 can control the shore landing and departure device 105 to enter the first state, and the shore landing and departure device 105 is lapped between the ship 200 and the floating platform 10. The preset time can be set according to actual needs, and this application does not limit it. For example, the preset time is 2 minutes. The proximity sensing device 106 can include a proximity sensor. When the proximity sensor senses that a ship 200 is docked at the ship docking position 101, it can output a sensing signal to the shore landing and departure control device 107.

[0086] In some embodiments, the onshore and offshore control device 107 can also be omitted, and the operation of the onshore and offshore device 105 is controlled by the main control device. The onshore and offshore device 105 can also include a hoisting mechanism, and the staff can operate the hoisting mechanism to hoist the discharged battery of the ship to the ship berth 101, or hoist the fully charged battery from the ship berth 101 to the ship 200.

[0087] As Figure 7b shown, the battery 300 located in the battery charging area 210 can be transported to the ship 200 via the lifting platform 30 and the onshore and offshore device 105, or the battery 300 unloaded from the ship 200 can be transported to the battery charging area 210 via the onshore and offshore device 105 and the lifting platform 30.

[0088] As Figure 8 shown, the battery swapping workstation 100 can also include a plurality of lifting platforms 30. The plurality of lifting platforms 30 can operate independently, which can meet the application scenarios with a high demand for battery swapping. The number of the lifting platforms 30 is not limited in this application and can be set according to actual needs. Since each lifting platform 30 operates independently, the operation of other lifting platforms 30 will not be affected when a certain lifting platform 30 fails, so that the battery 300 can be transported between the floating platform 10 and the battery swapping platform 20 in a timely manner.

[0089] The plurality of lifting platforms 30 can all be installed on the floating platform 10. Each lifting platform 30 is fixedly connected to the floating platform 10 and movably connected to the battery swapping platform 20, so that the lifting platform 30 can rise and fall with the rise and fall of the floating platform 10. By installing the lifting platform 30 on the floating platform 10, the lifting platform 30 will not be in direct contact with the water area, avoiding the corrosion of the water area on the lifting platform 30, which can extend the service life of the lifting platform 30 and enable the lifting platform 30 to operate safely and stably.

[0090] In some embodiments, a fence 108 can also be provided on the floating platform 10. The lifting platform 30 is located inside the fence 108, which can prevent the staff from entering or approaching the lifting platform 30 during the operation of the lifting platform 30 and avoid safety accidents. The number of the fences 108 can be the same as the number of the lifting platforms 30, that is, each lifting platform 30 can correspond to a fence 108.

[0091] As Figure 9 shown, the fence 108 can include a fence body 1081 and a fence door 1082. The fence door 1082 is movably connected to the fence body 1081. The fence door 1082 can be in an open or closed state relative to the fence body 1081.

[0092] As Figure 10As shown in the figure, the lifting platform 30 may include a support column 301, a platform body 302, a driving mechanism 303, a driving control device 304, and a first sliding member 308. The support column 301 is fixedly arranged on the floating platform 10, and the first sliding member 308 is fixedly connected to the support column 301. The first sliding member 308 is also movably connected to the battery swapping platform 20, and the support column 301 can move up and down with the lifting of the floating platform 10 through the first sliding member 308. The application does not limit the movable connection manner between the first sliding member 308 and the battery swapping platform 20. For example, the first sliding member 308 may be provided with pulleys, and the battery swapping platform 20 may be provided with slide rails adapted to the pulleys. The pulleys can slide up and down along the slide rails with the lifting of the floating platform 10, so that the lifting platform 30 can rise and fall with the lifting of the floating platform 10. The driving control device 304 may be arranged on the battery swapping platform 20 or the floating platform 10.

[0093] The support column 301 may include a support column body 3012 and a rack 3013 fixedly arranged on the support column body 3012. The driving mechanism 303 is fixedly connected to the platform body 302. The support column body 3012 is provided with a guide rail 3010. The driving mechanism 303 can be used to drive the platform body 302 to move up and down along the rack 3013 and the guide rail 3010.

[0094] In some embodiments, the lifting platform 30 may include two platform bodies 302 and two driving mechanisms 303. The two platform bodies 302 may be arranged oppositely, and the two platform bodies 302 can lift between the battery swapping platform 20 and the floating platform 10 relatively independently.

[0095] As Figure 11 shown in the figure, the driving mechanism 303 may include a driver 3039 and a gear 3040. The gear 3040 can be engaged with the rack 3013. The driver 3039 is used to drive the gear 3040 to move up and down along the rack 3013, and then the gear 3040 can drive the platform body 302 to move up and down.

[0096] The driving mechanism 303 may further include a second sliding member 3041. The second sliding member 3041 can be movably connected to the support column body 3012, so that the platform body 302 can lift between the battery swapping platform 20 and the floating platform 10 along the guide rail 3010 through the second sliding member 3041. The number of the second sliding members 3041 can be set according to actual needs, and the application does not limit this. By providing the second sliding member 3041, the friction when the platform body 302 moves relative to the support column body 3012 can be reduced, which is convenient for the driving mechanism 303 to drive the platform body 302 to move up and down along the rack 3013 and the guide rail 3010.

[0097] The platform body 302 may be provided with a platform support plate 3020 and a limiting member 3021 that opens and closes relative to the platform support plate 3020. The limiting member 3021 may be slidably engaged with the support column 301. When the limiting member 3021 is closed relative to the platform support plate 3020, it restricts the battery from being removed from or inserted into the platform support plate 3020; when the limiting member 3021 is opened relative to the platform support plate 3020, it allows the battery to be removed from or inserted into the platform support plate 3020.

[0098] Please refer to again Figure 10 , the first position sensing member 305 may be fixedly connected to the floating platform 10, and the first position sensing member 305 is also communicatively connected to the drive control device 304. For example, the first position sensing member 305 may be communicatively connected to the drive control device 304 in a wired manner. The first position sensing member 305 is used to sense the distance between the platform body 302 and the floating platform 10, and output the position state of the platform body 302 relative to the floating platform 10 to the drive control device 304. The drive control device 304 may control the operation of the platform body 302 according to the position state output by the first position sensing member 305. For example, the drive control device 304 may control the platform body 302 to decelerate according to the position state output by the first position sensing member 305, and dock with the lower docking portion 104 when the platform body 302 decelerates to a stop.

[0099] For example, the first position sensing member 305 is used to sense the approaching distance between the platform body 302 and the floating platform 10, and output the approaching position state of the platform body 302 relative to the floating platform 10. The drive control device 304 is used to control the platform body 302 to decelerate according to the approaching position state sensed by the first position sensing member 305, so as to control the platform body 302 to decelerate when descending to a certain specified position, so that the platform body 302 docks with the lower docking portion 104. The first position sensing member 305 is also used to sense the docking distance between the platform body 302 and the floating platform 10, and output the docking position state. The drive control device 304 is used to control the platform body 302 to stop according to the docking position state sensed by the first position sensing member 305, so as to control the platform body 302 to stop moving when descending to a certain specified position, so that the platform body 302 docks with the lower docking portion 104. For example, the driver 3039 is a brake deceleration motor. The drive control device 304 may control the driver 3039 to stop rotating and maintain the torque according to the docking position state sensed by the first position sensing member 305, so as to control the platform body 302 to stop moving when descending to a certain specified position. The driver 3039 uses a brake deceleration motor, which can achieve automatic locking and torque maintenance of the motor in case of sudden power failure, preventing the platform body 302 from falling.

[0100] For example, the first position sensing member 305 includes a first sensor mounting member 3051, a first sensor 3052, and a second sensor 3053. The first sensor mounting member 3051 is fixedly connected to the floating platform 10. The first sensor 3052 is fixedly arranged on the first sensor mounting member 3051, and the first sensor 3052 is used to sense the proximity distance between the platform body 302 and the floating platform 10. The second sensor 3053 is fixedly arranged on the first sensor mounting member 3051, and the second sensor 3053 is used to sense the docking distance between the platform body 302 and the floating platform 10. The second sensor 3053 may be located below the first sensor 3052.

[0101] The second position sensing member 306 may be fixedly connected to the battery swapping platform 20, and the second position sensing member 306 is also communicatively connected to the drive control device 304. For example, the second position sensing member 306 may be communicatively connected to the drive control device 304 by a wired or wireless manner. The second position sensing member 306 is used to sense the distance between the platform body 302 and the high-level docking portion 202 of the battery swapping platform 20, and output the position state of the platform body 302 relative to the high-level docking portion 202 to the drive control device 304. The drive control device 304 can control the operation of the platform body 302 according to the position state output by the second position sensing member 306, so that the platform body 302 can accurately dock with the high-level docking portion 202 of the battery swapping platform 20.

[0102] For example, the second position sensing member 306 is used to sense the proximity distance between the platform body 302 and the high-level docking portion 202, and output the proximity position state of the platform body 302 relative to the high-level docking portion 202. The drive control device 304 is used to control the deceleration of the platform body 302 according to the proximity position state sensed by the second position sensing member 306, so as to control the platform body 302 to decelerate when moving upward to a certain specified position, so that the platform body 302 can dock with the high-level docking portion 202. The second position sensing member 306 is also used to sense the docking distance between the platform body 302 and the high-level docking portion 202, and output the docking position state. The drive control device 304 is used to control the stop of the platform body 302 according to the docking position state sensed by the second position sensing member 306, so as to control the platform body 302 to stop moving when moving upward to a certain specified position, so that the platform body 302 can dock with the high-level docking portion 202.

[0103] For example, the second position sensor 306 includes a second sensor mounting member 3060, a third sensor 3061, and a fourth sensor 3062. The second sensor mounting member 3060 is fixedly connected to the battery swapping platform 20, and the third sensor 3061 is fixedly disposed on the second sensor mounting member 3060. The third sensor 3061 is used to sense the approaching distance between the platform body 302 and the high-level docking portion 202. The fourth sensor 3062 is fixedly disposed on the second sensor mounting member 3060, and the fourth sensor 3062 is used to sense the docking distance between the platform body 302 and the high-level docking portion 202. The third sensor 3061 may be located below the fourth sensor 3062.

[0104] Please refer to again Figure 11 , the platform body 302 may further be provided with a contact member 3028. One end of the contact member 3028 is fixedly connected to the platform body 302, and the other end of the contact member 3028 may be in contact with the first position sensor 305 or the second position sensor 306. For example, when the other end of the contact member 3028 is in contact with the first position sensor 305, the first position sensor 305 outputs a first sensing signal. When the other end of the contact member 3028 is in contact with the second position sensor 306, the second position sensor 306 outputs a second sensing signal. The drive control device 304 may control the operation of the platform body 302 according to the first sensing signal and the second sensing signal.

[0105] For example, the first position sensor 305 includes a first sensor 3052 and a second sensor 3053. The other end of the contact member 3028 may be in contact with the first sensor 3052 or the second sensor 3053, thereby triggering the first sensor 3052 or the second sensor 3053 to output a corresponding sensing signal. The second position sensor 306 includes a third sensor 3061 and a fourth sensor 3062. The other end of the contact member 3028 may also be in contact with the third sensor 3061 or the fourth sensor 3062, thereby triggering the third sensor 3061 or the fourth sensor 3062 to output a corresponding sensing signal when in contact.

[0106] Refer to Figure 12 As shown, it is a schematic flowchart of a method for replacing a ship battery provided by an embodiment of the present application. This method for replacing a ship battery can be applied to the battery swapping workstation 100 to achieve rapid battery swapping for the ship 200. The battery swapping workstation 100 includes a floating platform 10, a battery swapping platform 20, and a lifting platform 30 that can move up and down between the battery swapping platform 20 and the floating platform 10. The floating platform 10 is provided with a ship docking position 101, and a battery charging area 210 for placing and charging a discharged battery is provided on the battery swapping platform 20. In this embodiment, the method for replacing a ship battery may include:

[0107] Step S101: When receiving a first sensing signal that a ship 200 is docked at the ship docking position 101 and a second sensing signal that a discharged battery of the ship 200 is removed, randomly select a fully charged battery from the battery charging area 210, and transport the selected battery to the ship 200 via the lifting platform 30 and the floating platform 10.

[0108] In some embodiments, proximity sensors may be provided at the edge of the ship docking position 101 to sense whether a ship 200 is docked at the ship docking position 101 through the proximity sensors. The main control device 2030 can receive the first sensing signal that a ship 200 is docked at the ship docking position 101 by communicating with the proximity sensors. The ship 200 can establish a communication connection with the main control device 2030, and the ship system carried by the ship 200 can sense whether the battery is removed. When the discharged battery of the ship 200 is removed, the ship 200 can send a second sensing signal to the main control device 2030, so that the main control device 2030 can receive the second sensing signal that the discharged battery of the ship 200 is removed. When the main control device 2030 receives the first sensing signal that a ship 200 is docked at the ship docking position 101 and the second sensing signal that the discharged battery of the ship 200 is removed, it indicates that the ship 200 has a battery replacement requirement, and the main control device 2030 can randomly select a fully charged battery from the battery charging area 210 and transport it to the ship 200. For example, each battery includes rollers and can move autonomously, and has a path planning module, a sensing module and a communication module. The sensing module can obtain the starting position, the ending position and the surrounding environment information of the battery. The path planning module can plan a global path for the battery to move from the starting position to the ending position according to the starting position, the ending position and the surrounding environment information of the battery, and the battery can move autonomously according to the global path. The sensing module can include a lidar module or a camera module, and the path planning module can include a microprocessor, a storage device, etc. The storage device stores a path planning algorithm. The main control device 2030 also has a communication module to communicate with the battery, and the main control device 2030 is also provided with a scheduling management system, which can control and schedule multiple batteries.

[0109] In some embodiments, in order to transport the fully charged battery from the battery charging area 210 to the ship 200, the fully charged battery can be first transported from the battery charging area 210 to the high-level docking part 202, enter the platform body 302 via the high-level docking part 202 and be transported to the low-level docking part 104, and then move from the low-level docking part 104 to the ship berthing position 101 where the ship 200 is berthed, and then move the fully charged battery at the ship berthing position 101 to the ship 200. For example, when the main control device 2030 randomly selects a fully charged battery from the battery charging area 210, the scheduling management system can generate a scheduling task for the fully charged battery, and the scheduling task includes the task start point (the battery charging area 210) and the task end point (the ship berthing position 101 where the ship 200 is berthed). The battery can also communicate with the drive control device 304 to obtain the operation information of the platform body 302, which is convenient for the battery to enter and exit the platform body 302, and further can control the fully charged battery to autonomously move from the battery charging area 210 to the ship berthing position 101 where the ship 200 is berthed via the lifting platform 30.

[0110] In some embodiments, the floating platform 10 is provided with a landing and offshore device 105, and the landing and offshore device 105 can be arranged at the ship berthing position 101. After the fully charged battery moves from the battery charging area 210 to the ship berthing position 101, the main control device 2030 can also control the landing and offshore device 105 to move the fully charged battery at the ship berthing position 101 to the ship 200. For example, the landing and offshore device 105 is a hoisting mechanism, and the main control device 2030 controls the hoisting mechanism to move the fully charged battery from the ship berthing position 101 to the ship 200.

[0111] In some embodiments, the landing and offshore device 105 can also be a foldable boarding plank that can be lapped between the edge of the ship berthing position 101 and the ship 200, so that the battery can travel offshore or onshore between the edge of the ship berthing position 101 and the ship 200. The fully charged battery can also autonomously move from the ship berthing position 101 to the ship 200 through the landing and offshore device 105.

[0112] Step S102: Move the discharged battery unloaded from the ship 200 to the battery charging area 210 via the floating platform 10 and the lifting platform 30.

[0113] In some embodiments, the battery charging area 210 is provided with one or more charging devices 211. When the discharged battery of the ship 200 is unloaded, the discharged battery can be moved to the battery charging area 210 via the floating platform 10 and the lifting platform 30 to charge the discharged battery. To move the discharged battery from the ship 200 to the battery charging area 210, the discharged battery can first be moved from the ship 200 to the ship berth 101, and then the discharged battery at the ship berth 101 can be moved to the low-level docking part 104, enter the platform body 302 via the low-level docking part 104 and be transported to the high-level docking part 202, and then be moved to the battery charging area 210 by the high-level docking part 202. For example, the main control device 2030 can control the onshore and offshore device 105 to move the discharged battery of the ship 200 to the ship berth 101. The onshore and offshore device 105 is a hoisting mechanism, and the discharged battery is moved from the ship 200 to the ship berth 101 through the hoisting mechanism. The discharged battery located at the ship berth 101 can be added to the scheduling management system for management, so that the discharged battery can move from the ship berth 101 to the battery charging area 210 autonomously via the lifting platform 30.

[0114] In some embodiments, during the charging process of the discharged battery by the charging device 211, the main control device 2030 can communicate with the charging device 211 to obtain the power of the discharged battery in real time. When the main control device 2030 determines that the power of the discharged battery is greater than the preset power, the main control device 2030 can control the charging device 211 to stop charging the discharged battery, improving the safety of battery charging.

[0115] In some embodiments, a battery maintenance area 213 is also provided on the battery swapping platform 20. The discharged battery unloaded from the ship 200 can also be moved to the battery maintenance area 213 via the floating platform 10 and the lifting platform 30 for detection first. When it is detected that the discharged battery does not need to be repaired or maintained, it is then moved 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 that can detect the state of the discharged battery and a battery maintenance device 2131 that can repair or maintain the discharged battery.

[0116] In some embodiments, the battery swapping platform 20 is further provided with a power distribution device 204 and a fire ignition monitoring device 205. The power distribution device 204 is used to supply power to the charging device 211. The fire ignition monitoring device 205 can be arranged in the battery charging area 210. The fire ignition monitoring device 205 can be used to sense whether there is a battery on fire in the battery charging area 210. When the fire ignition monitoring device 205 senses that there is a battery on fire in the battery charging area 210, it can output a third sensing signal to the main control device 2030. The power distribution device 204 is also communicatively connected to the main control device 2030. When the main control device 2030 receives the third sensing signal, the main control device 2030 can control the power distribution device 204 to cut off the power supply to the charging device 211, so as to automatically cut off the power when a battery fire is detected, improving the safety of battery charging.

[0117] In some embodiments, a fire extinguishing device 212 is further arranged in the battery charging area 210. The fire extinguishing device 212 is electrically connected to the main control device 2030. When the main control device 2030 receives the third sensing signal, the main control device 2030 can activate the fire extinguishing device 212 to extinguish the fire on the battery. For example, the fire extinguishing device 212 is a sprinkler device. When the main control device 2030 receives the third sensing signal, it can activate the sprinkler head to spray water to extinguish the fire on the battery.

[0118] In some embodiments, the battery swapping platform 20 is further provided with a temperature sensor 206 and a ventilation device 207. The temperature sensor 206 and the ventilation device 207 can be arranged in the battery charging area 210. The temperature sensor 206 is used to sense the ambient temperature of the battery charging area 210. The main control device 2030 can control the operating state of the ventilation device 207 according to the ambient temperature sensed by the temperature sensor 206, so as to adjust the ambient temperature of the battery charging area 210, improving the charging efficiency and charging safety of the battery. The ventilation device 207 can be devices such as a fan or an air conditioner. Controlling the operating state of the ventilation device 207 can mean whether to turn on the ventilation device 207, adjusting the rotation speed, temperature, etc. of the ventilation device 207.

[0119] Refer to Figure 13 As shown, it is a schematic flowchart of a method for replacing a ship battery provided in another embodiment of the present application. This method for replacing a ship battery can be applied to the battery swapping workstation 100 to achieve rapid battery swapping for the ship 200. The battery swapping workstation 100 includes a floating platform 10, a battery swapping platform 20, and a lifting platform 30 that can move up and down between the battery swapping platform 20 and the floating platform 10. The floating platform 10 is provided with a ship docking position 101, and a battery charging area 210 for placing and charging a discharged battery is arranged on the battery swapping platform 20. In this embodiment, the method for replacing a ship battery may include:

[0120] Step S201: Sense whether a ship 200 is docked at the ship docking position 101.

[0121] In some embodiments, proximity sensors may be provided at the edge of the ship docking position 101, and the proximity sensors may be used to sense whether a ship 200 is docked at the ship docking position 101. The proximity sensors may be communicatively connected to the main control device 2030. When the proximity sensors sense that a ship 200 is docked at the ship docking position 101, the proximity sensors may output a first sensing signal to the main control device 2030.

[0122] Step S202: When it is sensed that a ship 200 is docked at the ship docking position 101, determine whether the ship 200 unloads a discharged battery.

[0123] In some embodiments, when it is sensed by the proximity sensors that a ship 200 is docked at the ship docking position 101, the main control device 2030 may also determine whether the ship 200 unloads a discharged battery by determining whether it receives a second sensing signal sent by the ship 200. For example, the ship 200 may establish a communication connection with the main control device 2030, and the ship system carried by the ship 200 may sense whether the battery is unloaded. When the discharged battery of the ship 200 is unloaded, the ship 200 may send a second sensing signal to the main control device 2030. When the main control device 2030 receives the second sensing signal sent by the ship 200, it is determined that the ship 200 unloads the discharged battery.

[0124] Step S203: When the discharged battery of the ship 200 is unloaded, randomly select a fully charged battery from the battery charging area 210, and convey the selected battery to the ship 200 via the lifting platform 30 and the floating platform 10.

[0125] In some embodiments, when it is determined that the discharged battery of the ship 200 is unloaded, it indicates that the ship 200 docked at the ship docking position 101 has a battery replacement requirement. The main control device 2030 may output a prompt message on the human-machine interface of the central control center that the ship docking position 101 needs a fully charged battery for battery replacement, and then arrange for the staff to randomly select a fully charged battery from the battery charging area 210 and convey it to the ship 200.

[0126] In some embodiments, the ship berth 101 may also be provided with a power replacement reminder device (such as a sound / light reminder device). When it is determined that the discharged battery of the ship 200 is removed, the main control device 2030 may control the power replacement reminder device to output a power replacement prompt message to remind the staff that the ship 200 has a power replacement requirement. Then, the staff can randomly select a fully charged battery from the battery charging area 210, move the battery to the floating platform 10 via the lifting platform 30, and then move the battery from the floating platform 10 to the ship 200. The battery can be designed as a cart-type battery pack or a trailer-type battery pack, and the battery may include rollers, so that the battery can be conveniently and quickly moved between the power replacement platform 20 and the ship 200.

[0127] In some embodiments, in order to convey the fully charged battery from the battery charging area 210 to the ship 200, the staff located on the power replacement platform 20 may first move the fully charged battery from the battery charging area 210 into the platform body 302 of the lifting platform 30 and start the lifting platform 30. The staff located on the floating platform 10 may move the fully charged battery out of the platform body 302 and convey it to the ship berth 101, and then move the fully charged battery at the ship berth 101 to the ship 200.

[0128] In some embodiments, the floating platform 10 is provided with a shore-to-offshore device 105, and the shore-to-offshore device 105 may be arranged at the ship berth 101. After the fully charged battery is moved to the ship berth 101, the staff can control the shore-to-offshore device 105 to move the fully charged battery at the ship berth 101 to the ship 200. For example, the shore-to-offshore device 105 is a hoisting mechanism, and the staff can control the hoisting mechanism to move the fully charged battery from the ship berth 101 to the ship 200.

[0129] In some embodiments, the shore-to-offshore device 105 may also be a foldable boarding plank that can be lapped between the edge of the ship berth 101 and the ship 200 for the battery to travel offshore or ashore between the edge of the ship berth 101 and the ship 200. When the foldable boarding plank is lapped between the edge of the ship berth 101 and the ship 200, the staff can also move the fully charged battery from the ship berth 101 to the ship 200 via the foldable boarding plank.

[0130] Step S204: Move the discharged battery removed from the ship 200 to the battery charging area 210 via the floating platform 10 and the lifting platform 30.

[0131] In some embodiments, the battery charging area 210 is provided with one or more charging devices 211. When the discharged battery of the ship 200 is removed, the discharged battery can be moved to the battery charging area 210 via the floating platform 10 and the lifting platform 30 to charge the discharged battery. In order to move the discharged battery from the ship 200 to the battery charging area 210, the staff located on the floating platform 10 can first move the discharged battery from the ship 200 to the ship berth 101, and then move the discharged battery at the ship berth 101 into the platform body 302 of the lifting platform 30 and start the lifting platform 30. The staff located on the battery swapping platform 20 can move the discharged battery out of the platform body 302 and transport it to the battery charging area 210. The staff can control the onshore and offshore device 105 to move the fully charged battery at the ship berth 101 to the ship 200. For example, the onshore and offshore device 105 is a hoisting mechanism, and the staff can control the hoisting mechanism to move the discharged battery from the ship to the ship berth 101. The onshore and offshore device 105 is a foldable boarding plank that can be lapped between the edge of the ship berth 101 and the ship 200. When the foldable boarding plank is lapped between the edge of the ship berth 101 and the ship 200, the staff can also move the discharged battery from the ship 200 to the ship berth 101 via the foldable boarding plank.

[0132] In some embodiments, during the charging process of the charging device 211 for the discharged battery, the main control device 2030 can communicate with the charging device 211 to obtain the power of the discharged battery in real time. When the main control device 2030 determines that the power of the discharged battery is greater than the preset power, the main control device 2030 can control the charging device 211 to stop charging the discharged battery, improving the safety of battery charging.
