[0002] Photovoltaic power generation is an important component of renewable energy, especially offshore photovoltaic power plants, which have developed rapidly due to their geographical advantages. However, during operation, offshore photovoltaic power plants face challenges such as salt spray corrosion, high humidity, and bird droppings due to the unique marine environment. These factors can severely affect the power generation efficiency and lifespan of the photovoltaic panels. Therefore, regular inspections and maintenance are necessary.

[0003] In existing technologies, maintenance is usually carried out by staff using maintenance vessels to conduct regular on-site inspections. However, manual inspection and maintenance of offshore photovoltaic systems suffers from problems such as low efficiency, high cost, and poor safety.

[0004] In the prior art, such as Chinese utility model patent with authorization announcement number CN219313048U, a photovoltaic inspection drone is disclosed, including a drone body; a connecting bracket connected to the bottom of the drone body; a landing gear disposed on the outside of the connecting bracket and connected to the drone body; a shooting unit disposed on the bottom of the drone body and rotatably connected to the connecting bracket; and a communication module disposed within the drone body. The drone, in conjunction with the shooting unit and communication module, enables the completion of inspection and maintenance tasks.

[0005] However, offshore photovoltaic power stations are generally located far from land, and their deployment area is large. This results in long single-time inspection and maintenance periods, consuming significant amounts of electricity and exhibiting poor continuous inspection capabilities. Furthermore, drones need to return to base for recharging after a period of operation, leading to low inspection and maintenance efficiency. Therefore, these systems are ill-suited to the inspection and maintenance tasks of offshore photovoltaic power stations. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation

[0026] In this embodiment, as Figure 1 As shown, the two mounting brackets 15 are spaced in the left-right direction, and the length of the mounting brackets 15 is in the front-back direction. The intelligent control center 2 is located at the front of the solar charging module 1.

[0027] refer to Figures 1 to 8This utility model discloses a marine photovoltaic operation and maintenance device (hereinafter referred to as the operation and maintenance device) with solar power supply function, including a drone 13. The drone 13 includes a drone body 14, which is equipped with an intelligent control center 2 and an identification module. The drone body 14 is equipped with a battery. The identification module includes a camera identification unit 4 set at the front end of the drone body. The drone body 14 is also equipped with a solar charging module 1. The solar charging module 1 includes a light intensity sensor, a mounting base 11, an angle adjustment module, and a solar panel 12. The solar panel 12 is rotatably mounted on the mounting base 11 through the angle adjustment module. The angle adjustment module drives the solar panel 12 to rotate according to the information of the light intensity sensor to adjust the angle of the solar panel 12. The solar panel 12 charges the battery.

[0028] In this embodiment, each drone 13 is equipped with an inspection area. The maintenance device also includes a drone bay mounted on a marine photovoltaic support platform within the inspection area. A wireless charging module is installed inside the drone bay, which can also be used to charge the maintenance device. By combining solar charging with wireless charging from the drone bay, the battery life requirements of the maintenance device are met, ensuring the orderly and reliable execution of inspection and maintenance tasks, and guaranteeing inspection and maintenance efficiency.

[0029] Specifically, in this embodiment, the UAV body 14 also integrates a radar sensor 9. Utilizing the radar sensor's time-of-flight and phase modulation principles, it integrates a scanning system and array detection to achieve real-time acquisition of 360° omnidirectional high-precision point cloud data. Combined with point cloud registration and rasterization processing, it outputs a three-dimensional spatial topology structure, enabling dynamic obstacle tracking and path planning. Specifically, as... Figure 1 As shown, a set of radar sensors is installed on each of the left and right sides of the robot body.

[0030] The Intelligent Control Center 2 consists of a multimodal processor, a dynamic scheduling module, and a communication interface. The multimodal processor generates control commands to achieve precise control and speed response of the robot, while optimizing resource allocation and energy consumption, automatically calibrating and updating the robot's environmental parameters in real time. The Intelligent Control Center 2 collects various signals based on its onboard radar, laser, and other sensors. It contains a digital intelligent terminal that collects, summarizes, and processes information. Based on the environmental information assessment by the central processing system, it achieves resource and energy allocation and dynamic scheduling of the robot. Simultaneously, it can aggregate the collected information to the backend to generate a summary report on the operation of the marine photovoltaic system.

[0031] The camera recognition unit 4 includes two multispectral cameras positioned at a distance from the front of the robot's main body along a left-right axis. Utilizing existing multi-channel spectral imaging technology, and equipped with a high-precision optical filter array and sensor, the multispectral cameras distinguish between dust, salt deposits, and algae through ultraviolet-visible-infrared three-band scanning. A quantitative model of the impact of dirt is established using the scanning information from the spectral recognition unit, calculating the efficiency loss rate based on dirt area × thickness × material. Specifically, the multispectral cameras can simultaneously acquire visible and near-infrared spectra, combined with adaptive exposure control and spectral feature fusion technology, to complete the reflectance inversion and material composition analysis of the target object.

[0032] Multispectral cameras can also be used to photograph the surface of photovoltaic panels. The captured images can be used for diagnosis via the intelligent control center 2 to determine the extent of contamination or damage to the photovoltaic panels. The information identified by the identification unit can be transmitted to the ground control center for diagnosis via the communication module integrated within the intelligent control center 2.

[0033] In other embodiments, the camera recognition unit 4 also includes an infrared thermal imaging camera, which is used to capture the light spot situation inside the photovoltaic panel to complete the camera inspection and maintenance.

[0034] In this embodiment, as shown in the figure, a set of mounting brackets 15 are respectively arranged on the left and right sides of the lower end of the UAV body 14. The length direction of the mounting bracket 15 extends into a horizontal frame and a cantilever 16 connecting the horizontal frame and the UAV body 14. The identification module also includes a laser identification unit 5. A set of laser identification units 5 is arranged on the cantilever 16 of each of the two mounting brackets 15, and the two sets of laser identification units 5 are symmetrically arranged. The laser identification unit 5 integrates a blue light-near infrared dual-frequency laser module, which, combined with existing multispectral non-destructive testing algorithms, can perform component microcrack scanning, realize laser identification inspection and maintenance, and improve the inspection effect.

[0035] In other embodiments, when meeting actual usage requirements, by increasing the laser output power, the high-power laser of the laser recognition unit 5 can also be used to non-contactly remove salt crystals or algae from the surface of the photovoltaic panel, realizing a reuse mode of low-power recognition and high-power removal.

[0036] A set of flight wings 3 are respectively set on the left and right sides of the upper part of the drone body 14. The flight wings 3 are equipped with rotors 31 to realize flight and attitude control.

[0037] Preferably, in this embodiment, the mounting base 11 is provided with a first mounting cavity 111 and a driving mechanism. A first rotating shaft 113 is rotatably mounted within the first mounting cavity 111. The driving mechanism drives the first rotating shaft 113 to rotate. Two sets of solar panels 12 are symmetrically arranged on the left and right sides of the first rotating shaft 113. The two solar panels 12 are connected and fixed to the first rotating shaft 113 via connecting rods 127. The driving mechanism can drive the first rotating shaft 113 to rotate, thereby causing the solar panels 12 fixed to the first rotating shaft 113 to rotate.

[0038] Specifically, such as Figure 2 , 7 As shown, the mounting base 11 is also provided with a second mounting cavity 112, which is located below the first mounting cavity 111. A second rotating shaft 114 is rotatably mounted in the second mounting cavity 112. The drive mechanism includes a first gear 115, a second gear 116, and a drive motor 7. The first gear 115 and the second gear 116 are respectively mounted on the first rotating shaft 113 and the second rotating shaft 114 with anti-rotation, and the first gear 115 and the second gear 116 mesh and transmit power. The drive motor 7 drives the second rotating shaft 114 to rotate.

[0039] The second rotating shaft 114 is driven to rotate by the drive motor 7, and the first gear 115 and the second gear 116 mesh with it, thereby driving the second rotating shaft 114 to rotate.

[0040] Specifically, such as Figure 2 , 7 As shown, a first cylinder 119 and a second cylinder 120 are vertically spaced at the upper end of the mounting base 11. The inner cavity of the first cylinder 119 forms the first mounting cavity 111, and the inner cavity of the second cylinder 120 forms the second mounting cavity 112.

[0041] A vertically extending slit 128 is provided at the middle of the first cylinder 119 along its length. The width of the slit 128 along the axial direction of the first cylinder 119 is adapted to the size of the connecting rod 127. The slit 128 extends to the lower part of the first cylinder 119, and the left and right sides of the slit 128 are inclined surfaces extending downwards, which expand the rotation range of the connecting rod 127.

[0042] An mounting sleeve 118 is fixedly installed at the position corresponding to the cut 128 on the first rotating shaft 113. The connecting rod 127 is an inclined rod extending obliquely upward. The inner end of the connecting rod 127 is fixed on the mounting sleeve 118, and the outer end of the connecting rod 127 is fixedly connected to the solar panel 12 on the corresponding side.

[0043] Specifically, in this embodiment, the first rotating shaft 113 has small-diameter sections at both its front and rear ends. The inner side of the small-diameter section is rotatably mounted in the first mounting cavity 111 via a bearing 117, and the outer side of the small-diameter section extends out to form a first cylindrical body 119, which is fitted with a first gear 115 to prevent rotation. Similarly, the two ends of the second rotating shaft 114 also extend out to form second cylindrical bodies 120, each fitted with a second gear 116. The two sets of first gears 115 and second gears 116 drive the first rotating shaft 113 to rotate, providing stability for angle adjustment. In this embodiment, the drive motor 7 is a self-locking motor. Utilizing the self-locking characteristic of the self-locking motor, the tilt position of the solar panel 12 can be maintained after the angle adjustment is completed, preventing swaying due to wind or other factors.

[0044] Specifically, in this embodiment, such as Figure 1 , 7 As shown, the intelligent control center 2 is located at the front of the mounting base 11. The first and second mounting cylinders are positioned near the front of the mounting base 11. The drive motor 7 is located on the rear side of the upper end of the mounting base 11, specifically on the motor mounting base 71 at the rear of the mounting base. The rotating shaft of the drive motor 7 is connected to the second rotating shaft 114 via a coupling 8, allowing the drive motor 7 to drive the second rotating shaft 114 to rotate. This configuration prevents the center of gravity of the UAV body 14 from shifting, ensuring flight stability.

[0045] In this embodiment, preferably, the solar panel 12 is a foldable solar panel 12. Specifically, the foldable solar panel 12 includes a first photovoltaic panel 121, a second photovoltaic panel 122, and a folding mechanism 123, wherein the first photovoltaic panel 121 and the second photovoltaic panel 122 are electrically connected. The inner end of the first photovoltaic panel 121 is connected to the connecting rod 127, and the outer end is hinged to the second photovoltaic panel 122, with its hinge axis extending in the front-back direction. The folding mechanism 123 drives the second photovoltaic panel 122 to rotate left and right relative to the first photovoltaic panel 121 to fold it.

[0046] Specifically, in this embodiment, when folded, the second photovoltaic panel 122 is located below the first photovoltaic panel 121, without affecting the power generation of the first photovoltaic panel 121 in the folded state. Simultaneously, a gap exists between the unfolded outline of the outer end of the second photovoltaic panel 122 and the flight rotor 31 to avoid interference. Furthermore, a buffer pad 129 is provided on the lower inner side of the first photovoltaic panel 121, corresponding to the inner position of the second photovoltaic panel 122 in the folded state, to prevent hard contact between the two.

[0047] Specifically, in this embodiment, a set of folding mechanisms 123 is provided on both the front and rear sides of the solar panel 12. Taking the front folding mechanism 123 as an example, as follows... Figure 2As shown, the folding mechanism 123 specifically includes a drive cylinder 124, a middle L-shaped connecting rod 125, and an end connecting rod 126. The opposite ends of the drive cylinder 124 and the end connecting rod 126 are respectively hinged to the first photovoltaic panel 121 and the second photovoltaic panel 122, and their hinge axes extend in the front-rear direction. The opposite ends of the drive cylinder 124 and the end connecting rod 126 are respectively hinged to both ends of the middle L-shaped connecting rod 125, which is located between the drive cylinder 124 and the end connecting rod 126. The connection between the horizontal and vertical sections of the middle L-shaped connecting rod 125 is hinged to the first photovoltaic panel 121.

[0048] Specifically, the cylinder body of the drive cylinder 124 is hinged to the first photovoltaic panel 121, and the cylinder rod of the drive cylinder 124 is hinged to the intermediate L-shaped connecting rod 125. In actual use, such as... Figure 2 As shown, the solar panel 12 is in a folded state. Taking the solar panel 12 on the left as an example, when the solar panel 12 needs to be unfolded, the drive cylinder 124 retracts, its cylinder rod retracts, driving the middle L-shaped connecting rod 125 to rotate clockwise, and the end connecting rod 126 follows the rotation. The second photovoltaic panel 122 rotates out clockwise until the second photovoltaic panel 122 is flush with the first photovoltaic panel 121. The drive cylinder 124 stops retracting and holds, completing the unfolding of the solar panel 12. When the solar panel 12 needs to be folded up, the operation is reversed.

[0049] By using the foldable solar panel 12, the area of ​​the solar panel can be adjusted according to the light intensity, thereby adjusting the power generation efficiency. When the power is sufficient, the solar panel 12 can be folded up to reduce wind resistance and improve flight performance.

[0050] Preferably, in this embodiment, a set of electromechanical claws 6 are respectively provided on the front and rear sides of the lower end of the horizontal frame of each mounting bracket 15. The electromechanical claws 6 can be used to clean up debris from the offshore photovoltaic power station and to help transport materials to assist in operation and maintenance.

[0051] Specifically, in this embodiment, such as Figure 8 As shown, the electromechanical gripper 6 includes a mounting housing 61, a push cylinder 63, a clamping jaw 69, and a connecting structure. An inner mounting cavity 62 is provided within the mounting housing 61. Openings communicating with the inner mounting cavity 62 are provided at both opposite ends of the mounting housing 61. The push cylinder 63 is located on the side of the mounting housing 61 facing the mounting bracket 15. The inner end of the push cylinder 63 is fixed to the mounting housing 61, and the outer end is fixedly connected to the mounting bracket 15. The cylinder rod of the push cylinder 63 forms a push rod 64, which passes through this opening and extends into the mounting cavity.

[0052] At the opening on the side of the mounting housing 61 facing away from the mounting bracket 15, two clamping claws 69 are symmetrically arranged laterally. The inner ends of the two clamping claws 69 extend into the mounting cavity 62 and slide laterally in cooperation with the mounting cavity 62. The length of the opening on this side extends laterally and its thickness matches the thickness of the clamping claws 69, forming a laterally sliding opening 694 for the clamping claws 69 to slide.

[0053] A connecting structure is provided between the end of the push rod 64 and the clamping claw 69. The push cylinder 63 drives the push rod 64 to move, and the transmission is carried through the connecting structure, so that the two clamping claws 69 move closer or further apart to achieve gripping and releasing.

[0054] In this embodiment, the connecting structure includes a first connecting rod 66, a second connecting rod 67, and a drive tooth 68. The inner end of the push rod 64 is fixedly connected to a connecting plate 65 extending laterally. The connecting structure includes two sets arranged symmetrically laterally, each set of connecting structures being connected to a mechanical claw.

[0055] In this embodiment, the drive tooth 68 is a sector tooth. A transverse slide rail 693 extending laterally is provided in the mounting cavity 62. A transverse slide groove 691 adapted to the transverse slide rail 693 is provided on the side of the clamping claw 69 facing the transverse slide rail 693. A transverse rack 692 extending laterally is provided at the inner end of the clamping claw 69. The drive tooth 68 is rotatably mounted in the mounting cavity through a rotating shaft. Specifically, the rotating shaft of the drive tooth 68 is rotatably engaged with the mounting cavity, and the drive tooth 68 is anti-rotated and mounted on its rotating shaft.

[0056] Taking one set of connection structures as an example, one end of the first connecting rod 66 is hinged to one lateral end of the connecting plate 65, and the other end is hinged to the second connecting rod 67. The other end of the second connecting rod 67 is anti-rotatingly engaged with the rotating shaft of the drive gear 68. The push cylinder 63 drives the push rod 64 to extend into the mounting cavity, the connecting rod 127 drives the first connecting rod 66 to rotate inward, which in turn drives the second connecting rod 67 to rotate. The second connecting rod 67 drives the drive gear 68 to rotate outward, and the drive gear 68 drives the rack to move laterally outward, thereby causing the mechanical gripper to open. The reverse action closes the mechanical gripper.

[0057] The working process for this application is as follows: When inspection and maintenance are required, UAV 13 takes off and inspects the area, using its identification module to identify stains, bird droppings, cracks, and debris. The intelligent control center 2 then transmits the information to the ground control center for assessment.

[0058] In the initial inspection state, the solar panel 12 is in the retracted state, using the first photovoltaic panel 121 to continuously power the battery, while the retracted state reduces wind resistance.

[0059] When the battery charge drops rapidly, the second photovoltaic panel 122 is unfolded using the folding mechanism 123 to increase the light-receiving area and improve charging efficiency.

[0060] During flight inspection, the direction of the sun is determined by the light intensity sensor. The intelligent control center 2 controls the rotation direction of the drive motor 7 based on the information from the light intensity sensor. The drive motor 7 drives the second shaft 114 to rotate. Through the transmission between the second gear 116 and the first gear 115, the first shaft 113 is driven to rotate, which in turn drives the solar panel 12 to rotate, so that the solar panel 12 is arranged facing the direction of sunlight, thereby improving the power generation efficiency.

[0061] During the inspection, when a large piece of debris is found, the drone 13 flies to the location of the debris, activates the push cylinder 63, and uses the electric mechanical claw 6 to grab the debris, completing the debris removal operation and maintaining the offshore photovoltaic power station.

[0062] In summary, the maintenance device of this application uses a solar charging module 1 to power the battery, thereby improving the endurance of the UAV 13. The light intensity sensor and the angle adjustment module work together to ensure that the solar panel 12 is always facing the sun, improving charging efficiency and increasing the duration of a single cruise. The camera recognition unit can collect image information of the marine photovoltaic system, and in conjunction with the intelligent control center 2 and the backend, analyze defects such as salt spray corrosion, bird droppings, dirt, and crack damage, to achieve unmanned inspection, thereby improving inspection efficiency and safety.

[0063] Example 2: This example provides a different solar charging module. Unlike Example 1, in this example, when meeting actual usage requirements, the rotating shaft of the drive motor is engaged with the first rotating shaft to prevent rotation. The drive motor drives the first rotating shaft to rotate, thereby driving the solar panel to rotate and change the orientation of the solar panel.

[0064] Example 3: This example provides a different solar charging module. Unlike Example 1, in this example, a rotating motor is used to directly drive the second photovoltaic panel to flip, thereby realizing the folding and storage of the solar panel.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0066] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0067] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
