In the description of the embodiments of this application, the meaning of "a plurality" is more than two, unless otherwise specifically defined.

[0051] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0055] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "linkage", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0056] In the related art, when a ship is out of power, it needs to be charged at a dock. However, the space at the dock is limited and it is impossible to accommodate equipment with a large floor area in a narrow space. Usually, only some small-power integrated charging devices are arranged at the dock, which cannot meet the charging needs of ships with a large battery capacity.

[0057] Based on the above considerations, in order to arrange fully functional ship charging equipment at a narrow dock, the charging module and the cable transmission module are designed independently and separately arranged on the first platform and the second platform arranged up and down in the load module, so as to give sufficient arrangement space for the charging module and the cable transmission module in a limited space, and then improve the charging capacity of the ship charging equipment, thus better meeting the charging needs of ships with a large battery capacity. That is to say, by setting a load module with a first layer platform and a second layer platform, the charging module and the cable transmission module can be better arranged. On the one hand, components with a larger model and power can be selected for the charging module to improve the charging capacity of the charging module, thus better meeting the charging needs of ships with a large battery capacity. On the other hand, the arrangement space of the cable transmission module is relatively sufficient, so that the cable transmission module and the number of cables can be flexibly arranged. After the number of cables is increased, the charging capacity of the charging module can also be better improved.

[0058] The following refers to Figures 1-17 Describe the ship charging device 100 according to the embodiments of the present application.

[0059] Please refer to Figures 1-5 as shown in Figure 1 is a schematic structural diagram of the ship charging device 100 from the first angle of some embodiments of the present application. Figure 2 is a schematic structural diagram of the ship charging device 100 from the second angle of some embodiments of the present application. Figure 3 is a schematic structural diagram of the ship charging device 100 from the third angle of some embodiments of the present application. Figure 4 is a schematic structural diagram of the ship charging device 100 from the fourth angle of some embodiments of the present application. Figure 5 is a schematic structural diagram of the load module 3 from the first angle of some embodiments of the present application.

[0060] According to the ship charging device 100 of the embodiment of the present application, as Figures 1-4 shown, the ship charging device 100 includes a load module 3, a charging module 1, and a cable transmission module 2. The load module 3 includes a first platform 31 and a second platform 32 arranged in the vertical direction. The second platform 32 is located above the first platform 31. The charging module 1 is arranged on the first platform 31, and the cable transmission module 2 is arranged on the second platform 32. The cable transmission module 2 includes a cable 24 and a charging gun 27. One end of the cable 24 is electrically connected to the charging module 1, and the other end is connected to the charging gun 27. Among them, as Figure 5 shown, both the first platform 31 and the second platform 32 include: a plurality of cross beams and a plurality of longitudinal beams. The cross beams and the longitudinal beams are arranged at an angle, and both the cross beams and the longitudinal beams are integrally formed metal parts, and the cross beams and the longitudinal beams are welded together.

[0061] That is to say, the charging module 1 and the cable transmission module 2 are respectively integrated and designed, and then installed at different positions. Thus, by arranging the load module 3 with a double-layer platform on the dock 7, the equipment layout space on the dock 7 can be increased. The first platform 31 is only used to arrange the charging module 1 alone, and the layout space of the charging module 1 is relatively sufficient. The charging module 1 can select electrical components with a larger model and a higher charging power, which can improve the charging ability of the charging module 1 and can better meet the charging requirements of the ship 6 with a large amount of electricity. The second platform 32 is only used to arrange the cable transmission module 2, and the layout space of the cable transmission module 2 is relatively sufficient, which is conducive to the layout of the position of the cable transmission module 2. Even two or more cable transmission modules 2 can be arranged on the second platform 32. In this way, without changing the total number of the cables 24, the number of the cables 24 on each cable transmission module 2 can be reduced, so as to effectively simplify the cable transmission module 2 and reduce the production cost of the cable transmission module 2. In addition, if the total number of the cables 24 is increased, each cable transmission module 2 can share the number of the cables 24 well, so as to relieve the pressure of the cable transmission module 2 on the number of the cables 24. And after the total number of the cables 24 is increased, the charging efficiency of the charging module 1 can also be improved well, and the rapid energy replenishment requirement of the high-power ship 6 can be better met.

[0062] Exemplarily, the cross beam and the longitudinal beam are perpendicular to each other, so as to enclose a rectangular space between the cross beam and the longitudinal beam. It can be understood that the cross beam and the longitudinal beam may not be perpendicular to each other, so as to enclose a triangular or diamond-shaped space between the cross beam and the longitudinal beam. The present application does not limit this.

[0063] Exemplarily, both the cross beam and the longitudinal beam are made of H-shaped steel, and the cross beam and the longitudinal beam are connected by welding, with high connection strength and good stability.

[0064] In the above example, by setting the load module 3 with a first-layer platform and a second-layer platform, the charging module 1 and the cable transmission module 2 can be better arranged. On the one hand, the charging module 1 can select electrical components with larger models and powers, improving the charging capacity of the charging module 1, so as to better meet the charging requirements of the ship 6 with a large battery capacity. On the other hand, the layout space of the cable transmission module 2 is relatively sufficient, enabling the number of the cable transmission module 2 and the cable 24 to be flexibly arranged. After the number of the cable 24 is increased, the charging capacity of the charging module 1 can also be better improved. The platform constructed by the cross beam and the longitudinal beam can better reduce the weight of the platform while ensuring the structural strength.

[0065] In the above example, the charging module 1 and the cable transmission module 2 are designed separately, and each module is independently processed and assembled. They can be increased or decreased on the first-layer platform and the second-layer platform according to actual needs. Each module is transported separately, which can reduce the risks of being too high, too wide, and too heavy during transportation, so that the ship charging device 100 of the present application is convenient for transportation and can be quickly assembled on-site at the dock 7, with a short construction period.

[0066] In the above example, the load module 3 can be built with metal materials or can be a reinforced concrete structure, etc., and the present application does not limit this.

[0067] In some embodiments of the present application, the load module 3 includes a plurality of platform layers arranged in the up-and-down direction. Among them, the platform layer located at the uppermost part is the second platform 32, and the remaining at least one platform layer is the first platform 31.

[0068] Exemplarily, the number of the platform layers arranged in the up-and-down direction can be three, four, five, etc., and the present application does not limit this. By arranging three or more platform layers, the layout space of the equipment can be further increased.

[0069] Exemplarily, when there are multiple platform layers, by using the platform layer located at the uppermost part as the second platform 32, the space limitation of the load module 3 on the cable transmission module 2 can be reduced. That is, the load module 3 only provides a bearing function through the second platform 32 and does not limit the cable transmission module 2 in the horizontal space and the vertical space. In this way, the flexibility of the cable transmission module 2 is not easily interfered. Thus, the cable transmission module 2 can flexibly transmit the cable 24 in the horizontal space and the vertical space. When the size of the ship 6 and the charging position of the battery device 5 of the ship 6 change, the cable transmission module 2 can better transport the charging gun 27 at the end of the cable 24 to the charging position of the ship 6, with good flexibility.

[0070] Exemplarily, one or more first platforms 31 may be provided. That is, in the up-down direction, multiple layers of first platforms 31 may be provided. Thus, the layout space of the charging modules can be further increased. After the space is increased, on the one hand, electrical components with larger models and powers can be selected. On the other hand, the layout quantity of the charging modules can also be increased, thereby preferably increasing the charging capacity of the ship charging device 100, and further preferably meeting the charging requirements of the ship 6 with a large battery capacity.

[0071] Exemplarily, two or more charging modules may also be arranged on one first platform 31 to increase the charging capacity of the ship charging device 100, and the present application does not limit this.

[0072] Exemplarily, one of the multiple platform layers may also be a third platform, and the third platform may place other electrical components of the ship charging device 100, or may also place spare parts of the charging module 1 and the cable transmission module 2, so as to facilitate the maintenance of the charging module 1 and the cable transmission module 2.

[0073] In the above examples, by providing multiple layers of platform layers, the space of the load-carrying module 3 can be preferably increased, so that the charging module 1 and the cable transmission module 2 can be preferably arranged, and it is also beneficial to increase the quantity of the charging module 1 and the cable transmission module 2 to further improve the charging efficiency and charging capacity of the ship charging device 100.

[0074] Please refer to Figures 6-8 , Figure 6 which is a schematic structural diagram of the load-carrying module 3 from a second angle in some embodiments of the present application. Figure 7 which is a schematic structural diagram of the load-carrying module 3 from a third angle in some embodiments of the present application. Figure 8 which is a schematic structural diagram of the load-carrying module 3 from a fourth angle in some embodiments of the present application.

[0075] In some embodiments of the present application, such as Figures 5-8As shown in the figure, the load module 3 further includes: support legs 33, support columns 34, angle codes 35, guardrails 36, cable grooves 37 and ladders 38. There are multiple support legs 33, which are connected below the first platform 31 to separate the first platform 31 from the ground. The support columns 34 are arranged between the first platform 31 and the second platform 32 to separate the first platform 31 from the second platform 32. There are multiple angle codes 35. The first platform 31 and the support columns 34, and the second platform 32 and the support columns 34 are detachably connected by the angle codes 35 to the guardrails 36. The guardrails 36 are connected to the upper side of the second platform 32 and extend along the outer periphery of the second platform 32. The cable groove 37 is connected between the first platform 31 and the second platform 32, and the cable 24 is threaded through the cable groove 37. The ladder 38 is connected between the first platform 31 and the second platform 32.

[0076] That is to say, the arrangement of multiple support legs 33 can make the first platform 31 more stable, avoid the intrusion of ground moisture and sundries. After the charging module 1 is arranged on the first platform 31, the charging module 1 is not easily eroded, and it is also beneficial to repair the bottom of the charging module 1. The support columns 34 are arranged between the first platform 31 and the second platform 32, which can better bear the second platform and the cable transmission module 2 arranged on the second platform 32. Moreover, the frame structure constructed by the first platform 31, the second platform 32 and multiple support columns 34 has good ventilation, which is beneficial to the heat dissipation of the charging module 1 and can also better repair the charging module 1.

[0077] Furthermore, the detachable connection realized by the angle codes 35 can reduce the assembly difficulty and improve the assembly efficiency. In addition, the angle codes 35 can also share the stress when two adjacent components are connected, making the connection between the two components more firm and reliable. Moreover, after the angle codes 35 are damaged, they can be directly replaced, and both the maintenance efficiency and the maintenance cost are relatively low.

[0078] Furthermore, by arranging the guardrails 36 on the second platform 32, safety protection can be provided for the operators to prevent accidental falls of personnel. Exemplarily, the second platform 32 can be a rectangular platform, and four guardrails 36 are arranged on the four sides of the second platform 32 respectively. The four guardrails 36 are independent of each other, and the connection between two adjacent guardrails 36 can be detachable or not connected. This application does not limit this.

[0079] Furthermore, the cable 24 of the cable transmission module 2 needs to extend downward and be electrically connected to the charging module 1 on the first platform 31. The cable groove 37 can better limit and sort out the cable 24, which is beneficial to the arrangement of the cable 24, making the cable 24 more neat, and can also better reduce the interference between the cable 24 and other components, and can improve the reliability of the cable transmission module 2.

[0080] Further, the ladder 38 is connected between the first platform 31 and the second platform 32, which can facilitate personnel to move up and down between the two platforms, improving operation convenience and work efficiency.

[0081] Exemplarily, a welded connection may be provided between the first platform 31 and the support leg 33.

[0082] In the above example, the load-bearing structure is relatively simple and easy to build, which can provide sufficient layout space for the charging module 1 and the cable transmission module 2, and has high reliability and strong practicability.

[0083] Please refer to Figure 9 and Figure 10 , Figure 9 which is a schematic structural view of the charging module 1 from the first angle of some embodiments of the present application. Figure 10 is Figure 9 a cross-sectional view along line A-A in

[0084] In some embodiments of the present application, as shown in Figure 9 and Figure 10 , the charging module 1 includes: a protective box body 11 and a power supply device 12, a terminal, a transformer 14, a monitoring room 15, a high-voltage cabinet 16, a communication cabinet 17, a UPS 18, and a low-voltage cabinet 10 disposed in the protective box body 11. Among them, the charging module 1 further includes: a cooling fan 19, and the cooling fan 19 is disposed on the box wall of the protective box body 11.

[0085] That is to say, the protective box body 11 can play a role in protecting the power supply device 12, the terminal, the transformer 14, the monitoring room 15, the high-voltage cabinet 16, the communication cabinet 17, the UPS 18, the low-voltage cabinet 10, etc. In addition, it should be noted that in the charging device, the "terminal" refers to the end device or interface in the charging module 1 that is directly connected to the electrical equipment or battery. It is the "last link" in the charging process and is responsible for transmitting electrical energy to the target device. The UPS 18 (Uninterruptible Power Supply) is a device used to provide continuous and stable power supply for the charging device when the power supply fails or the voltage is abnormal.

[0086] Exemplarily, the load-bearing module 3 can occupy the entire space of the dock 7, and the size of the first platform 31 of the load-bearing module 3 can be equivalent to the size of the dock 7.

[0087] Exemplarily, the protection box 11 can occupy the entire space of the first platform 31, so that the space inside the protection box 11 is relatively large. Multiple power supply devices 12 can be installed inside the protection box 11, so that the charging module 1 has a greater power. Moreover, with sufficient space, a larger-sized transformer 14 can also be arranged, and the quantity and specifications of the remaining components and auxiliary equipment can be increased according to requirements. For example, the power of the charging module 1 can be 4 MW or more, so as to better meet the charging and power consumption needs of the large electric ship 6.

[0088] Furthermore, the cooling fan 19 is arranged on the box wall of the protection box 11, which can better transfer the heat generated by the electrical components inside the protection box 11 to the outside of the protection box 11, so that the electrical components inside the protection box 11 are at an appropriate operating temperature, which is beneficial to the stable operation of the charging module.

[0089] In the above example, through the integrated charging module, it is beneficial to layout the positions of the protection box 11 and the power supply device 12, terminal, transformer 14, monitoring room 15, high-voltage cabinet 16, communication cabinet 17, UPS 18, and low-voltage cabinet 10 arranged inside the protection box 11. It has good compactness and can also better increase the quantity and specifications of electrical components such as the power supply device 12, so as to better increase the power of the charging module 1, and thus can better meet the charging requirements of large electric ships.

[0090] The charging module in the above example is an integrated and modular power equipment, which integrates the power supply device 12, control system, heat dissipation device, protection unit, fire protection facilities, etc. into a protection box 11, with flexible layout, strong environmental adaptability, and high safety and reliability.

[0091] Please refer to Figures 11-13 , Figure 11 which is a schematic structural diagram of the cable transmission module 2 from the first angle in an embodiment of the present application. Figure 12 which is a schematic structural diagram of the cable transmission module 2 from the second angle in an embodiment of the present application. Figure 13 which is a schematic structural diagram of the cable transmission module 2 from the third angle in an embodiment of the present application.

[0092] Please refer to Figures 14-16 , Figure 14 which is a schematic structural diagram of the ship charging device 100 charging the ship 6 from the first angle in some embodiments of the present application. Figure 15 which is a schematic structural diagram of the ship charging device 100 charging the ship 6 from the second angle in some embodiments of the present application. Figure 16 which is a schematic structural diagram of the ship charging device 100 charging the ship 6 from the third angle in some embodiments of the present application.

[0093] In some embodiments of the present application, as Figures 11-16 shown, the cable transmission module 2 further includes: a base 21, a conveying component 22 and a driving component 23. The conveying component 22 is installed on the base 21, and the cable 24 is arranged on the conveying component 22; the driving component 23 is installed on the base 21 and is used to drive the conveying component 22 so that the conveying component 22 conveys the cable 24.

[0094] That is to say, when the ship 6 needs to be charged, the cable 24 can be conveyed through the conveying component 22. For example, the charging gun 27 of the cable 24 can be transported above the battery device 5 of the ship 6, and then the conveying component 22 releases the cable 24, so that the charging gun 27 can land at the battery device 5 better. The staff can insert the charging gun 27 into the charging port of the battery device 5. Thus, when the size of the ship 6 changes, the cable transmission module 2 can drive the conveying component 22 through the driving component 23, and the conveying component 22 can change the position of the charging gun 27 of the cable 24, so as to charge the charging device of the ship 6 better according to the actual situation.

[0095] In the above example, by driving the conveying component 22 through the driving component 23, the conveying component 22 can adjust the position of the cable 24, so as to charge better according to the position of the charging device of the actual ship 6, with good flexibility.

[0096] In some embodiments of the present application, as Figures 11-13 shown, the conveying component 22 includes: a fixed seat 221, a cable reel 222 and a telescopic arm assembly 223. The fixed seat 221 is installed on the base 21, the cable reel 222 is rotatably installed on the fixed seat 221, the cable 24 includes at least one cable 24, and at least one turn of the cable 24 is wound around the cable reel 222. The telescopic arm assembly 223 includes a main arm 2231, at least one stage of telescopic arm 2232 and a telescopic oil cylinder 2233. The main arm 2231 is installed on the fixed seat 221, the telescopic arm 2232 is telescopically arranged in the main arm 2231, and the telescopic oil cylinder 2233 is connected between the main arm 2231 and the telescopic arm 2232 and is used to drive the telescopic arm 2232 to extend or retract from the main arm 2231. Cable restraint members 2234 are arranged on both the main arm 2231 and the telescopic arm 2232. The cable restraint members 2234 have cable holes, and the cable 24 passes through the cable holes.

[0097] That is to say, the cable 24 can be wound and stored on the cable reel 222. During the specific assembly process, one end of the cable 24 with the charging gun 27 can sequentially pass through the cable holes on the main arm 2231 and the telescopic arm 2232. Thus, when the telescopic oil cylinder 2233 drives the telescopic arm 2232 to perform telescopic movement, the cable 24 is released from the cable reel 222, and the telescopic movement of the telescopic arm 2232 can adjust the position of the charging gun 27, with good flexibility.

[0098] Exemplarily, when the telescopic arm 2232 performs telescopic movement, the cable reel 222 can also rotate through the third driving member 233, rather than rotating by the dragging of the cable 24. In this way, damage to the cable 24 can be reduced. Additionally, when the telescopic arm 2232 performs a retracting movement, the cable reel 222 can rotate under the drive of the driving member to wind up the cable 24, which can avoid the prolapse phenomenon of the cable 24 caused by the retraction of the telescopic arm 2232, can better protect the cable 24, and can also reduce interference with other structures. Moreover, the cable reel 222 can rotate under the drive of the driving member and can also actively adjust the release length of the cable 24, thereby facilitating the operator to drag the cable 24 to the designated charging position.

[0099] Exemplarily, the telescopic arm 2232 can have only one stage, that is to say, there is only one telescopic arm 2232, and the telescopic arm 2232 is telescopically installed within the main arm 2231.

[0100] Exemplarily, the telescopic arm 2232 can have multiple stages, that is, there are multiple telescopic arms 2232. The multiple telescopic arms 2232 are sleeved in sequence, and adjacent two telescopic arms 2232 can perform relative telescopic movement. The outermost telescopic arm 2232 is telescopically installed within the main arm 2231. In one example, one telescopic oil cylinder 2233 can be provided, that is, one end of the telescopic oil cylinder 2233 is connected to the main arm 2231, and the other end is connected to the innermost telescopic arm 2232 among the multiple telescopic arms 2232; in another example, multiple telescopic oil cylinders 2233 can be provided, and the multiple telescopic arms 2232 and the multiple telescopic oil cylinders 2233 are in one-to-one correspondence, that is, one end of each telescopic oil cylinder 2233 is connected to the main arm 2231, and the other end is connected to the corresponding telescopic arm 2232. In this way, each stage of the telescopic arm 2232 can independently perform telescopic movement, with strong flexibility.

[0101] Exemplarily, there can be one cable 24 or multiple cables 24. For example, there can be two, three, four, five, six, seven, eight, etc. cables 24, and this application does not make any restrictions. Each cable 24 has one charging gun 27. Thus, the charging requirements of the ship 6 can be better met.

[0102] Exemplarily, the cable restraint 2234 can be two connected rollers, and the grooves between the two rollers face each other and form a wire harness hole.

[0103] In the above example, by providing the cable reel 222 and the telescopic arm 2232, the charging gun 27 can be better transported to different positions according to the actual situation, so as to better match the positions of the charging devices of different ships 6, with good flexibility and strong practicability.

[0104] In some embodiments of the present application, as Figures 11-13 shown, the fixed seat 221 is rotatably mounted on the base 21, the main arm 2231 is rotatably mounted on the fixed seat 221, and the driving assembly 23 further includes: a first driving member 231 and a second driving member 232. The first driving member 231 is mounted on the base 21 and is used to drive the fixed seat 221 to rotate, and the second driving member 232 is mounted between the fixed seat 221 and the main arm 2231 and is used to drive the main arm 2231 to rotate.

[0105] That is to say, the first driving member 231 can drive the fixed seat 221 to rotate in the horizontal direction, and further enable the active arm to also rotate in the horizontal direction. The second driving member 232 can drive the main arm 2231 to swing in the up and down directions. Thus, the cable 24 conveying module can better adjust the positions of the cable 24 and the charging gun 27 according to the position of the charging device of the ship 6.

[0106] In the above example, through the first driving member 231 and the second driving member 232, the active arm can be made to rotate in the horizontal direction and can also be made to swing in the up and down directions, which can improve the flexibility of the cable transmission module 2.

[0107] In some embodiments of the present application, the cable transmission module 2 further includes: a third driving member 233. The third driving member 233 is mounted on the fixed seat 221 and is used to drive the cable reel 222 to rotate forward or reverse.

[0108] That is to say, when the telescopic arm 2232 performs a telescopic action, the cable reel 222 can also rotate through the third driving member 233 without rotating by being dragged by the cable 24. In this way, the damage to the cable 24 can be reduced. In addition, when the telescopic arm 2232 performs a retracting action, the cable reel 222 can rotate under the drive of the driving member, so as to store the cable 24, which can avoid the prolapse of the cable 24 caused by the retraction of the telescopic arm 2232, can better protect the cable 24, and can also reduce the interference with other structures. And the cable reel 222 can rotate under the drive of the driving member, and can also actively adjust the release length of the cable 24, so as to facilitate the operator to drag the cable 24 to the designated charging position.

[0109] In the above example, by driving the cable reel 222 to rotate through the third driving member 233, the cable 24 can be better released and wound up, the cable 24 can be protected, and the damage to the cable 24 can be reduced.

[0110] Next, refer to Figures 11-13 Describe the structure of the cable transmission module 2 of a specific embodiment of the present application.

[0111] The cable transmission module 2 includes a base 21, an oil station 25, a support frame, an electric control box, a slip ring box, a first reduction gear and a first servo motor (i.e., the first driving member 231) connected by transmission, a second servo motor and a second reduction gear (i.e., the third driving member 233) connected by transmission, a cable reel 222, a rotating shaft 224, a telescopic oil cylinder 2233, a main arm 2231, a vision camera 26, a charging gun 27, a cable 24, a telescopic arm 2232, a second driving member 232 (the second driving member 232 may include an oil cylinder), a nylon sheave, a pin shaft 28, a fixing seat 221 and other accessories. The fixing seat 221 bears the entire device and is fixed on the base 21, and is driven by the first servo motor and the first reduction gear to realize the horizontal rotation of the actuator; the cable 24 is wound in the inner groove of the cable reel 222, and the cable reel 222 is installed on the fixing seat 221 through the rotating shaft 224 and is driven by the second servo motor and the second reduction gear. The main arm 2231 is connected to the upper part of the second driving member 232 through the pin shaft 28, and the other end of the second driving member 232 is hinged to the side of the fixing seat 221, and the pitching in the height direction is realized through the action of the telescopic oil cylinder 2233. The telescopic arm 2232 is embedded in the main arm 2231 and contacts through a nylon sleeve. One end of the telescopic oil cylinder 2233 is hinged to the inner side of the main arm 2231, and the other end of the telescopic oil cylinder 2233 is hinged to the inner side of the telescopic arm 2232, and the linear motion of the actuator is realized through the action of the telescopic oil cylinder 2233. The oil station 25 provides power for the telescopic oil cylinder 2233, and controls the telescopic and stroke of the oil cylinder through an equal proportion regulating valve and an electromagnetic reversing valve. After the cable 24 exits from the cable reel, it enters the groove of the nylon sheave, and the second servo motor and the second reduction gear drive the nylon sheave. The first servo motor, the second servo motor, the telescopic oil cylinder 2233, and the second driving member 232 cooperate with each other to realize the transmission of the cable 24 and the charging gun 27. Two or more sets of the cable transmission module 2 can be arranged according to needs.

[0112] In some embodiments of the present application, as Figures 14-16 shown, the ship charging device 100 further includes: a protective wall 4, and the protective wall 4 is arranged on the side of the load module 3 close to the sea water.

[0113] Exemplarily, the protective wall 4 can be made of fiberglass material.

[0114] In the above example, during stormy weather, the protective wall 4 can better block the seawater from washing the equipment, prevent the equipment from short - circuiting and leaking electricity, and the equipment performance is more stable.

[0115] In the related art, during the charging process of the electric ship 6 at the port terminal 7, usually after the ship 6 docks at the berth of the terminal 7, the crew remotely notifies, and the operation and maintenance personnel in the monitoring room 15 of the terminal 7 come to the charging equipment beside the terminal 7. The operation and maintenance personnel observe the position of the box - type power supply on the ship 6, and then use the operation handle to guide the cable 24 conveying mechanism to transmit the cable 24 and the charging gun 27 above the power supply on the deck of the ship 6. The crew grabs the charging gun 27 on the deck and drags it to the designated position, and then inserts the charging gun 27 into the charging socket of the power supply with insufficient power.

[0116] In some embodiments of the present application, the ship charging device 100 further includes: a sensor module and a control module. The sensor module is used to obtain a position signal, and the control module is used to control the cable transmission module 2 to convey the cable 24 according to the position signal.

[0117] That is to say, in the related art, the charging process of the ship 6 highly depends on the intervention of the shore - side operation and maintenance personnel, including the operation and maintenance personnel observing the docking position of the ship 6 with the naked eye, manually operating the handle to control the transmission of the cable 24 and the charging gun 27, and manually operating the handle to retract the cable 24 and the charging gun 27, resulting in a large investment in labor costs. In the present application, by setting the sensor module, the position of the ship 6 can be better sensed, and then the control module can better control the cable transmission module 2 to convey the cable 24 according to the position signal, so that the charging gun 27 can better reach the charging device of the ship 6 that needs to be charged. At this time, only the charging gun 27 needs to be inserted into the charging device, which is simple, convenient, and has a high charging efficiency.

[0118] In the above example, through the sensor module and the control module, the cable transmission module 2 can be better controlled to convey the cable 24 according to the position signal, so that the charging gun 27 can better reach the charging device of the ship 6 that needs to be charged. At this time, only the charging gun 27 needs to be inserted into the charging device, which is simple, convenient, and has a high charging efficiency.

[0119] Please refer to Figure 17 , Figure 17 , which is the charging flowchart of the ship charging device 100 for the ship 6 in some embodiments of the present application.

[0120] Exemplarily, the sensor module may include a vision camera 26. Thus, through the ship GPS positioning system, APP charging start system, cloud platform, device PLC interconnection, charging module 1, cable transmission module 2, vision camera 26 positioning system, and voice broadcast system interconnection. Based on this, the degree of equipment automation, intelligence, and shore - side unmanned operation can be better improved, the labor cost can be reduced, and the work efficiency can be improved. Specifically, asFigure 17 As shown, after the power-depleted ship 6 sails into the charging berth of the dock 7 and docks, the crew uses the APP charging module 1 to click the charging button, and the ship GPS transmits the coordinate information of the ship 6 to the PLC system of the ship charging device 100 through the cloud platform. The PLC controls the main arm 2231 of the cable transmission module 2 to lift, the fixed seat 221 to rotate, and the telescopic arm 2232 to extend. At this time, the vision camera 26 fixed to the lower part of the telescopic arm 2232 moves to the GPS-positioned location. The vision camera 26 performs visual recognition and position positioning on the box-type power supply on the power-depleted ship 6 and transmits the signal to the PLC. The PLC controls the cable transmission module 2 to actively adjust each movement posture, so that the charging gun 27 moves to a position directly above the battery device 5 of the specified ship 6 more precisely. The cable transmission module 2 actively lowers the charging gun 27 to the charging port of the battery device 5 of the ship 6. The crew on the deck grabs the charging gun 27 and inserts it into the charging seat. The charging module 1 performs signal detection on the battery device 5 of the ship 6. After successful handshaking, high voltage is applied, and the battery device 5 of the power-depleted ship 6 starts charging. After the battery device 5 of the ship 6 is fully charged, an electrical signal is given to the cloud platform to reach the PLC and control the charging module 1 to cut off the high voltage. A voice broadcast announces that the charging is full. The crew pulls out the charging gun 27 and clicks the system reset through the APP. The cloud platform sends a message to the PLC, and the charging module 1 and the cable transmission module 2 are reset. A voice broadcast announces that the charging is over and the ship should leave the charging berth. The ship 6 leaves the charging berth, completing the entire energy replenishment process for the ship 6.

[0121] In some embodiments of the present application, the sensor module includes: a vision camera 26 or a lidar.

[0122] In the above example, both the vision camera 26 and the lidar can preferably obtain the relative positions of the charging gun 27 and the battery device 5 of the ship 6, so as to more precisely control the position of the charging gun 27 relative to the charging device of the ship 6, and thus can improve the charging efficiency of the ship 6.

[0123] In some embodiments of the present application, the ship charging device 100 further includes: a monitoring system and a voice broadcast system. The monitoring system is installed on the load module 3 and is used to record monitoring information. The voice broadcast system is installed on the load module 3, and the voice broadcast system is used to emit corresponding prompt voices according to the charging status of the charging module 1 and / or the charging status of the battery device 5 of the ship 6.

[0124] That is to say, the monitoring system is installed in the cargo module 3, which can record monitoring information such as the operation of the charging device and the environmental status throughout the process, provide detailed data support for equipment fault troubleshooting and performance optimization, and ensure the traceability of the charging process of the ship 6. The voice broadcast system is also located in the cargo module 3, and corresponding prompt voices are emitted according to the charging status of the charging module 1 and the battery device 5 of the ship 6. For states such as charging start, full charge, and abnormality, the crew can be informed in a clear voice in a timely manner, avoiding missing key information due to negligence, reducing the workload of manual frequent inspection of the equipment, and improving work efficiency. The two work together, not only enhancing the safety and reliability of the ship charging device 100, but also realizing intelligent and user-friendly management, reducing the potential risks during the charging process of the ship 6, and providing strong guarantee for the safe navigation and efficient operation of the ship 6.

[0125] In the above example, the monitoring system and the voice broadcast system work together, not only enhancing the safety and reliability of the ship charging device 100, but also realizing intelligent and user-friendly management, reducing the potential risks during the charging process of the ship 6, and providing strong guarantee for the safe navigation and efficient operation of the ship 6.
