[0056] This embodiment provides an automatic charging device for offshore photovoltaic (PV) operation and maintenance platforms. This device is an intelligent energy replenishment system specifically designed for offshore PV power plants. Its core function is to solve the problem of continuous power supply for maintenance vessels, drones, and underwater inspection equipment during operation and maintenance. By integrating PV power generation, energy storage, and intelligent charging technologies, this device achieves energy self-sufficiency and efficient utilization, significantly reducing carbon emissions and operation and maintenance costs associated with traditional fuel-fired power generation.

[0057] like Figure 1 As shown, the automatic charging device of the offshore photovoltaic operation and maintenance platform includes a charging pile body 1, a control component, a guiding component 3, a moving component 4, and a fixed component 5, forming an efficient and reliable energy supply system.

[0058] The charging pile 1 is located at the shore end 200 and is used to dock with the charging device 2 on the hull 100 for charging. Specifically, the charging pile 1 has a charging slot, and the charging device 2 has a charging interface. Charging is achieved by docking the charging interface with the charging slot. The guiding component 3 is connected to the control component and is configured to guide the hull 100 from the operating water area to the effective docking area of ​​the charging pile 1 and accurately optically align the charging device 2 and the charging pile 1. The moving component 4 is connected to the control component and is located on the hull 100. The moving component 4 is configured to adjust the position of the charging device 2 for docking with the charging pile 1. The fixing component 5 includes a ship end fixing module 51 located on the hull 100 and a shore end fixing module 52 located at the shore end 200. The ship end fixing module 51 and the shore end fixing module 52 are detachably connected to lock and fix the charging device 2 and the charging pile 1. It should be noted that the marine photovoltaic operation and maintenance platform in this embodiment can be understood as the hull 100 itself.

[0059] The snap-fit ​​alignment of the charging device 2 on the offshore photovoltaic operation and maintenance platform is a core element in ensuring the reliability of automatic charging. The aforementioned structure enables a two-stage alignment mechanism of "coarse alignment - fine alignment." Combined with the synergistic effects of optical guidance, mechanical adjustment, and locking, it achieves precise docking and locking of the operation and maintenance platform and the charging pile 1. This not only makes the operation and maintenance platform more stable relative to the charging device 2, but also allows workers to perform construction work on three sides of the charging device 2 in this charging mode, greatly reducing the difficulty of on-site monitoring and handling temporary problems, and improving operational safety and efficiency. The fixing component 5 secures the hull 100, ensuring its stability during operation and effectively coping with the complex environment of high humidity, high salinity, and turbulent waves at sea, thus ensuring operational safety and reliability. The moving component 4 improves the accuracy of charging docking and the adaptive capability of the automatic charging device 2 to the offshore operation and maintenance platform, demonstrating strong practicality and providing core technical support for the long-term stable charging of the offshore photovoltaic operation and maintenance platform.

[0060] Specifically, the core objective of "coarse alignment" is to guide the operation and maintenance platform from the working water area to the effective docking area of ​​the charging pile 1 and perform preliminary positioning, laying the positional foundation for "fine alignment". This process mainly relies on the collaborative work of the guiding component 3 and the moving component 4.

[0061] Specifically, the guiding component 3 includes a light source, a beam splitter, and a photodetector. The light source is located at the shore end 200 and is connected to the control component. The beam splitter is located at the shore end 200 and is used to convert the optical signal emitted by the light source into a visual positioning path. The photodetector is located at the hull 100 and is connected to the control component. The photodetector can capture optical signals, convert the optical signals into electrical signals, and transmit them to the control component to obtain the alignment deviation between the charging device 2 and the charging pile 1.

[0062] When the maintenance platform needs charging, the control component sends a charging request, and the guidance component 3 immediately starts working. The light source emits an optical signal of a specific wavelength, which, after refraction by a beam splitter, forms a guide beam area covering a range of 50 meters, creating a visual guidance path. A photoelectric detector on the hull 100 captures this optical signal in real time, converts the light signal into an electrical signal, and transmits it to the control component. The control component combines this with the position coordinate data of the charging pile 1 to calculate the relative distance, offset angle, and heading deviation between the hull 100 and the charging pile 1, thereby obtaining the alignment deviation data between the charging device 2 and the charging pile 1. It is understood that the specific values ​​described above, such as "50 meters," are merely illustrative and do not represent a uniquely determined value. In practical applications, the specific value can be set according to actual needs.

[0063] Optionally, the moving component 4 includes a sensor, a drive device, and a transmission device. The sensor is connected to the control component and is used to collect the sway data of the hull 100 in real time and feed back the attitude information of the hull 100 to the control component. The drive device is connected to the control component and is mounted on the hull 100. One end of the transmission device is connected to the output end of the drive device, and the other end is connected to the charging device 2. The transmission device can adjust the position of the charging device 2 according to the attitude information.

[0064] Alternatively, the drive unit includes a motor connected to the control component. The sensor and the control component provide bidirectional feedback, and the control component drives the motor. The motor drives the transmission device to achieve precise alignment of the photovoltaic operation and maintenance platform.

[0065] The transmission device includes a transmission mechanism, a rotating rod, a moving rod, a moving base plate, and a docking base plate. The transmission mechanism is mounted on the hull 100, and its input end is connected to the output end of the drive device. One end of the rotating rod is connected to the output end of the transmission mechanism. One end of the moving rod is hinged to the other end of the rotating rod. The moving base plate is connected to the other end of the moving rod, and the charging device 2 is mounted on the moving base plate. The docking base plate is mounted on the hull 100, and the moving base plate is located above the docking base plate and is movably connected to it.

[0066] While the control component calculates the alignment deviation data between the charging device 2 and the charging pile 1, the sensors in the moving component 4 collect real-time data on the swaying of the hull 100 caused by sea winds and waves, feeding the attitude information back to the control component. The control component then drives the motor to adjust the position of the moving base plate through a transmission mechanism to achieve attitude compensation. Under the dual guidance of optical guidance and attitude compensation, the hull 100 gradually approaches the charging pile 1. When the photoelectric detector detects that the optical signal intensity reaches a preset threshold (e.g., the hull 100 enters within 13 meters of the charging pile), and the lateral offset of the hull 100 and the charging pile 1 is ≤30cm and the longitudinal deviation is ≤50cm, the coarse alignment stage is completed, and the system automatically switches to the fine alignment mode. This stage effectively solves the problem of long-distance positioning of the hull 100 in the marine environment, eliminating large positional deviations for subsequent precise docking. It is understood that the specific values ​​described above, such as "3 meters," "30cm," and "50cm," are only illustrative examples and do not represent unique values. In practical applications, the specific values ​​can be set according to actual needs.

[0067] Optionally, the transmission device further includes a guide rail and a slider. One of the moving substrate and the docking substrate has a guide rail, and the other has a slider, with the slider and guide rail slidably connected. This structure enables a movable connection between the moving substrate and the docking substrate. In this embodiment, the bottom of the moving substrate has a slider, and the docking substrate has a guide rail. Of course, the movable connection between the moving substrate and the docking substrate is not limited to this; it can also be achieved through a roller and guide rail for a rolling connection.

[0068] The core objective of "precise alignment" is to accurately adjust the position of the charging device 2 and to complete the mechanical snap-fit ​​fixation between the hull 100 and the shore end 200. This process mainly relies on the coordinated operation of the guiding component 3, the moving component 4, and the fixing component 5.

[0069] Precise alignment is crucial for stable connection. Through the high-precision optical positioning of the guiding component 3, the micron-level adjustment of the moving component 4, and the mechanical locking of the fixing component 5, a closed loop from "position alignment" to "fixed connection" is completed. After coarse alignment, the light source of the guiding component 3 switches to a high-precision focusing mode. The beam splitter focuses the beam into a precise positioning spot with a diameter of 5cm. The photodetector captures the center position of the spot and provides real-time feedback on the alignment deviation between the hull 100 and the fixing slot of the charging pile body 1, with an accuracy of ±0.1mm. It is understood that the specific values ​​described above, such as "5cm," are merely illustrative and do not represent the only definitive value. In practical applications, the specific value can be set according to actual needs.

[0070] Simultaneously, the moving component 4 initiates fine-tuning: Using the docking substrate as a fixed reference, the control component, based on the deviation data from the photoelectric detector, drives the motor to link the rotating rod and the moving rod via a transmission mechanism. The moving rod attaches to the moving substrate and performs bidirectional fine-tuning along the X and Y axes to compensate for the slight swaying of the hull caused by waves. During the adjustment process, the sensor continuously collects the position data of the moving substrate, forming bidirectional feedback with the control component to ensure that the adjustment accuracy meets the snap-fit ​​requirements.

[0071] In this embodiment, the ship-end fixing module 51 serves as the core mechanical connection mechanism between the offshore photovoltaic maintenance vessel and the shore-end charging pile. Its core function is to achieve locking and fixing through precise docking of the "ship-end component - shore-end fixing column," employing a three-level linkage design of "positioning - nesting - locking." The ship-end fixing module 51 includes a drive unit, a fixing block, a rotating block, a locking device, and matching connectors. The drive unit is mounted on the hull 100. The fixing block is fixedly connected to the movable base plate. The fixing block has a fixing hole, and the rotating block has a snap-fit ​​hole. The rotating block is connected to the output end of the drive unit and can rotate under the drive of the drive unit to make the snap-fit ​​hole fit with the fixing hole, i.e., the two holes are perfectly aligned. The locking device includes a threaded rod and a nut. The threaded rod passes through the fixing hole and the snap-fit ​​hole and is locked by the nut, thereby achieving locking and fixing of the fixing block and the rotating block. Both the fixing hole and the snap-fit ​​hole are through holes with smooth inner walls.

[0072] In this embodiment, the shore-end fixing module 52 includes a fixing post, which is fixedly installed on the shore end 200. The fixing post is spaced apart from the charging pile body 1. The side of the fixing post facing the hull 100 has an arc-shaped positioning surface, and the fixing block has an arc-shaped positioning groove that matches the positioning surface. By using the arc-shaped positioning surface and the arc-shaped positioning groove for positioning, automatic centering can be achieved to eliminate gaps. The large contact area reduces contact stress on the contact surface, thereby reducing the risk of wear and surface crushing. Additionally, it improves repeatability accuracy. Optionally, the positioning surface on the fixing post is a convex arc-shaped surface, and the positioning groove on the fixing block is a concave arc-shaped groove. Preferably, the fixing post has a cylindrical structure, and its outer circular surface can fit into the arc-shaped groove.

[0073] Optionally, the fixing post is provided with a reserved hole for connection with the threaded rod, thereby realizing the locking of the fixing block, the fixing post and the rotating block. The reserved hole is a through hole with a smooth inner wall.

[0074] When the ship positioning system (GPS + LiDAR) detects that the alignment deviation between the fixing hole of the fixing block and the charging slot of the charging pile body 1 is ≤0.5mm, the system triggers the start signal of the fixing component 5 and completes the mechanical locking process in the following four steps:

[0075] 1. Initial alignment and fitting: The arc-shaped groove of the fixing block fits tightly with the arc-shaped surface of the fixing column, and at the same time, the fixing hole of the fixing block is initially aligned with the arc-shaped surface of the fixing column. The guide effect of the groove wall is used to correct the slight deviation within ±0.1mm, forming a longitudinal positioning reference.

[0076] 2. Snap-fit ​​hole nesting and locking: The drive unit receives control commands and drives the rotating block to rotate around its output shaft. During the rotation, the position signal is fed back in real time through the photoelectric sensor to ensure that the snap-fit ​​hole of the rotating block and the fixing hole of the fixing block are completely matched, and the arc surface of the shore-end fixing column is firmly restricted in the arc groove, limiting the lateral and circumferential displacement.

[0077] 3. Threaded rod insertion and positioning: The threaded rod is inserted from the fixing hole on one side of the fixing block, and passes through the fixing hole of the fixing block, the reserved hole of the shore-end fixing column, and the snap-fit ​​hole of the rotating block in sequence, ensuring that the threaded rod does not get stuck in the inner wall of the through hole;

[0078] 4. Locking and fixing completed: The operator rotates the wing nut, and the fixing block, shore-end fixing post and rotating block are pressed and fixed by the thread preload, thereby realizing the locking and fixing of charging device 1 and shore end 200; an anti-loosening washer can also be set at the locking point of the wing nut. After the anti-loosening washer is deformed by pressure, it fills the thread gap and realizes anti-loosening locking.

[0079] Optionally, the fixing component 5 also includes a locking force detection element to perform alignment verification after the snap-fit ​​is completed. Specifically, the locking force detection element detects whether the locking force reaches a preset value to ensure stability against wind and waves, and the photoelectric detector reconfirms the optical alignment accuracy. After the dual verification is passed, the automatic charging device 2 starts the charging process. After charging is completed, the automatic charging device 2 automatically releases and disconnects from the charging pile body 1.

[0080] The automatic charging device for the offshore photovoltaic operation and maintenance platform in this embodiment also includes safety protection components, including anti-fall railings. These railings surround the charging pile body 1 to prevent accidents such as workers falling into the water during offshore monitoring and operations. The anti-fall railings have movable grooves and limiting latches. The movable grooves are used to adjust the position of the anti-fall railings as they are locked in place. The anti-fall railings include multiple spaced-apart railings, and the limiting latches are used to adjust the distance between adjacent railings.

[0081] Throughout the alignment process, the anti-fall guardrails around the charging pile body 1 are adjusted to the appropriate position through the moving groove and the limit lock, providing safety protection for the alignment operation and further ensuring the safety and reliability of the operation.

[0082] Optionally, the safety protection components also include life vests and life rings, both of which are hung on fall arrest railings for immediate use in case of emergency during on-site operations. The life vests are equipped with Beidou positioning devices, which can quickly and accurately locate and rescue people who fall into the water.

[0083] Optionally, such as Figure 2 As shown, the bow of the hull 100 is equipped with an anchor chain 6, which is used to anchor and fix the hull during automatic charging, maintain stability during automatic charging, and prevent the hull 100 from drifting.

[0084] In this embodiment, the automatic charging device for the offshore photovoltaic operation and maintenance platform includes two charging devices 2, two guiding components 3, two moving components 4, two fixing components 5, and two charging pile bodies 1. Specifically, a charging device 2, a guiding component 3, and a fixing component 5 are respectively provided on both sides of the hull 100. The two charging devices 2 are symmetrically arranged about the central axis 101 of the hull 100, the two guiding components 3 are symmetrically arranged about the central axis 101, and the two fixing components 5 are symmetrically arranged about the central axis 101. The two charging pile bodies 1 are arranged facing each other, and the two charging devices 2 are respectively connected to the two charging pile bodies 1 one by one.

[0085] The hull and charging pile sections achieve precise docking through the coordinated control of control components: when the maintenance vessel approaches the shore-based charging pile, the control components automatically identify the charging pile's power supply capacity, prioritizing the allocation of power from the shore-based energy storage module or directly utilizing the power generation of the offshore photovoltaic array; simultaneously, the BeiDou positioning + lidar combined positioning system is activated, combined with AI algorithms to correct the hull's attitude and position in real time, dynamically compensating for hull misalignment caused by ocean currents and waves, ensuring docking accuracy meets requirements. Furthermore, the fixed component 5 is equipped with environmental monitoring sensors to collect real-time data such as wind speed and wave height, dynamically adjusting to ensure power generation stability, while the charging interface on the charging device 2 has an adaptive voltage regulation function to ensure safe device connection. This modular design ensures system scalability and achieves multi-device compatibility through standardized interfaces, providing solid support for the intelligent operation and maintenance of offshore photovoltaic power plants.
