Description

Technical Field

[0001] This invention belongs to the field of navigation buoy cleaning technology, and in particular relates to an in-situ cleaning device, cleaning vessel and cleaning method for marine buoys. Background Technology

[0002] Buoys, as vital facilities for maritime navigation and positioning, play an irreplaceable role in ensuring maritime traffic safety and identifying marine shipping lanes. They typically consist of a cylindrical float, a support structure, and solar panels, and float in the ocean for extended periods. The colors of the buoys not only serve an identification function but also reflect their operational status; therefore, maintaining the cleanliness and vibrancy of the colors is crucial.

[0003] However, due to the unique nature of the marine environment, birds often perch on buoys, resulting in bird droppings and other dirt adhering to their surfaces. Bird droppings are highly adhesive, affecting the buoy's paint finish, operational efficiency, and solar charging performance. Long-term accumulation of bird droppings not only reduces the buoy's visual appeal but also affects its solar panels and can even accelerate aging and corrosion, ultimately impacting its navigational capabilities.

[0004] Given the importance and urgency of buoy cleaning, there is a need for a device that can clean the dirt off the surface of buoys during buoy inspections, ensuring the brightness of the buoy's paint and the normal operation of the solar panels. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an in-situ cleaning device, cleaning vessel and cleaning method for marine buoys, in order to solve the problem that bird droppings and other dirt accumulate on the surface of marine buoys, affecting the buoy's navigational function.

[0006] To achieve the above and other related objectives, the present invention provides an in-situ cleaning device, a cleaning vessel, and a cleaning method for marine buoys.

[0007] One of them is an in-situ cleaning device for marine buoys, used to cover and clean buoys from top to bottom, including a connecting base, a cleaning bucket and a tightening rope; The cleaning tub is rotatably hung on the lower side of the connecting base and can be driven to rotate relative to each other by a drive mechanism; The cleaning tub has no bottom. The tub shell is provided with a first reinforcement structure and a second reinforcement structure along the generatrix and circumferential direction, respectively. The first cleaning structure is provided on the inner side of the tub shell. The bottom of the tub shell is rotatably attached to a tub bottom ring. The tub bottom ring includes two layers: a bottom ring shell and an elastic membrane, with the elastic membrane located on the inner side. The tightening rope is located between the bottom ring shell and the elastic membrane. After the cleaning bucket covers the buoy, the tightening rope is tightened, and the elastic membrane is tied to the outer periphery of the buoy.

[0008] Optionally, the drive mechanism includes a gear ring, a gear, and a drive motor; The gear ring is fixedly disposed on the outer periphery of the connecting base; The gear is installed in the cleaning tub and meshes with the gear ring; The drive motor is mounted on the connecting base and is connected to and drives the gear to rotate via a drive shaft.

[0009] Optionally, the drive shaft is arranged along the first reinforcing structure and extends into the bottom of the cleaning tub; The bottom of the cleaning tank is also provided with a second cleaning structure, which is also driven by the drive shaft and includes a cleaning ring, a driven shaft and a cleaning roller. The cleaning ring is fixedly connected to the bottom of the first reinforcing structure, which extends beyond the cleaning tank. The first reinforcing structure has a notch. The driven shaft is rotatably disposed at the notch and tangential to the cleaning ring. The drive shaft contacts the driven shaft and transmits power. The cleaning roller is sleeved on the driven shaft.

[0010] Optionally, the cleaning roller includes an inner ring, an outer ring, a connecting column, and a pressure sensor; The inner diameter of the inner ring is fixedly fitted with the driven shaft, and a plurality of connecting posts are connected between the outer circular surface of the inner ring and the inner circular surface of the outer ring. A plurality of pressure sensors are disposed on the outer circular surface of the inner ring. The outer ring is made of a cleaning friction material, and the connecting post is made of a material that deforms under force and can recover. When the outer ring is squeezed, the outer ring and the connecting post deform, and the inner circular surface of the outer ring squeezes the pressure sensor of the outer circular surface of the inner ring.

[0011] Optionally, the first cleaning structure includes a clamp and a nozzle assembly along the first reinforcing structure; The two clamping plates protrude from the inside of the barrel shell, and the nozzle assembly is located between the two clamping plates, facing the central area of ​​the barrel shell.

[0012] Optionally, the first cleaning structure further includes a cleaning rod along the first reinforcing structure; The two ends of the cleaning rod are respectively connected to the inside of the barrel shell by two telescopic components.

[0013] Optionally, the cleaning structure on the cleaning bar is the same as that on the cleaning roller.

[0014] Optionally, a pull rope device is also provided in the interlayer between the bottom ring shell and the elastic membrane. There are two pull rope devices, which are respectively connected to the two ends of the tightening rope and can be tightened. The tightening rope is wound more than one turn in the interlayer between the bottom ring shell and the elastic membrane.

[0015] One of them is a marine buoy in-situ cleaning vessel, which includes a hull, a lifting mechanism, a telescopic mechanism, and a marine buoy in-situ cleaning device as described above. The lifting mechanism is installed on the hull, the telescopic mechanism is fixedly installed at the end of the boom of the lifting mechanism, and the connecting base of the in-situ cleaning device for marine buoys is fixedly connected to the telescopic end of the telescopic mechanism.

[0016] One method for in-situ cleaning of marine buoys, using a marine buoy in-situ cleaning vessel as described above, includes the following steps: A vessel used for in-situ buoy cleaning at sea approaches the target buoy. Adjust the angle and height of the lifting mechanism to cover the buoy from top to bottom with the in-situ cleaning device for the marine buoy; Cleaning near the buoy water level: The drive motor drives the driven shaft to rotate, and the driven shaft drives the barrel shell and the cleaning roller to rotate. The barrel shell rotates around the outer circumference of the buoy, and the cleaning roller rotates around its own axis and contacts the outer circumference of the buoy. The telescopic mechanism adjusts the height of the cleaning roller along the axis of the buoy. Cleaning the upper surface of the buoy: The rope puller tightens the rope, which tightly binds the elastic membrane to the outer periphery of the buoy to form a sealed interface. The drive motor drives the driven shaft to rotate, which in turn drives the barrel shell and the cleaning rod to rotate. The nozzle group sprays out cleaning water. After cleaning, the cleaning water in the cleaning barrel is extracted. The drive motor stops working, the rope puller loosens the tightening rope, the elastic membrane rebounds and detaches from the buoy shell, and the lifting mechanism lifts the in-situ cleaning device of the marine buoy and detaches it from the buoy.

[0017] As described above, the in-situ cleaning device, cleaning vessel, and cleaning method for marine buoys of the present invention have at least the following beneficial effects: This in-situ buoy cleaning device achieves efficient and environmentally friendly cleaning with its unique design. Through a clever combination of an elastic membrane and a tightening rope, the device can closely conform to buoys of different sizes, forming a sealed cleaning space. This effectively collects and recycles cleaning water, avoiding detergent pollution of the marine environment. Simultaneously, the combination of high-pressure jet rinsing and water jet rinsing ensures cleaning quality, significantly improving buoy cleanliness and cleaning efficiency. Furthermore, the device utilizes a drive mechanism to rotate the cleaning tank, achieving automated cleaning, which not only greatly improves cleaning efficiency but also reduces the labor intensity and risks of manual cleaning. In summary, this device, combined with its accompanying cleaning methods, not only provides superior cleaning results but also has significant environmental benefits. It balances efficiency and automation, offering a superior solution for the cleaning and maintenance of marine buoys, and is of great significance for protecting the marine ecological environment and extending the service life of buoys.

Detailed Implementation

[0030] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0031] Please see Figures 1 to 11It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0032] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0033] Please see Figures 1-11 This invention provides an embodiment of an in-situ cleaning device, cleaning vessel, and cleaning method for marine buoys.

[0034] Among them, an in-situ cleaning device for marine buoy 9 is used to cover and clean buoy 9 from top to bottom, including a connecting base 8, a cleaning bucket and a tightening rope 4; The cleaning tank is rotatably attached to the underside of the connecting base 8 and can be driven by a drive mechanism to rotate relative to the connecting base 8. The cleaning tank has no bottom, so it can cover the buoy 9 like a hat; The outer shell 70 of the cleaning tub is provided with a first reinforcing structure 71 and a second reinforcing structure 72 along the generatrix and circumferential directions, respectively. A first cleaning structure is provided inside the outer shell 70. A tub bottom ring is rotatably attached to the bottom of the outer shell 70. The outer shell 70 and the tub bottom ring can also rotate relative to each other. To achieve this rotation, the bottom ring shell 73 is attached to the outer shell 70 via a sliding snap-fit ​​structure. (See reference...) Figure 7 In the left cross-section, the sliding snap-fit ​​structure includes protrusions and grooves located on the bottom ring shell 73 and the barrel shell 70 respectively and cooperating with each other. A sealing strip should be provided at the sliding interface. The barrel bottom ring includes two layers: the bottom ring shell 73 and the elastic membrane 74. The elastic membrane 74 is located on the inner side, that is, the side of the elastic membrane 74 facing the inner buoy 9. The top of the bottom ring shell 73 is slidably connected to the barrel shell 70. The contact parts between the outer side of the bottom ring shell 73 and the barrel shell 70 and its reinforcing structure are also in a sliding relationship. The elastic membrane 74 is provided on the inner side of the bottom ring shell 73. The tightening rope 4 is located between the elastic membrane 74 and the bottom ring shell 73. The tightening rope 4 is positioned between the bottom ring shell 73 and the elastic membrane 74. The tightening rope 4 should be wound more than one turn. After the cleaning bucket covers the buoy 9, the tightening rope 4 is tightened from both ends, and the elastic membrane 74 will be bound to the outer periphery of the buoy 9. Figures 2-5 As shown, where Figure 5 The dotted line indicates the initial state, at which point the cleaning device and buoy 9 are not yet connected. The specific situation of the bottom ring of the bucket is as follows: the tightening rope 4(B) is not tightened, and the elastic membrane 74(B) is in a retracted and taut state. Once the cleaning device covers the buoy 9, the connection begins. Specifically, the tightening rope 4(A) is tightened, and at the same time, the tightening rope pulls the elastic membrane 74(A) to adhere tightly to the outer periphery of the buoy 9. The elastic membrane 74 can be a rubber membrane. Once it adheres tightly to the outer periphery of the buoy 9, a sealed interface is formed, allowing the bucket shell 70 to contain the cleaning water without leaking from the bottom ring of the bucket.

[0035] To allow for the recovery of the cleaning water in the cleaning tank after cleaning, a water suction pipe needs to be installed inside the tank. This pipe can be a flexible tube and should have a redundant length to accommodate a certain degree of tank torsion. The water pipe of nozzle assembly 61 can be reused, for example, by installing a one-way valve at the end of the pipe. Figure 4 and Figure 8 As shown, during water rinsing, the one-way valve 610 closes, preventing rinsing water from flowing out of the end of the water pipe and allowing it to be sprayed only from the nozzle assembly 61; when the rinsing water is withdrawn, the one-way valve 610 opens, and the rinsing water is drawn out of the tank. One-way nozzles with one-way valves can be used to prevent unintended backflow of rinsing water during rinsing.

[0036] The main working process of the above embodiments is as follows: The cleaning device is mounted on the workboat via a crane. The base 8 is connected and fixed to the crane, forming the body of the cleaning device. When cleaning the buoy 9, the cleaning device covers the buoy 9 from top to bottom, then cleans the bottom ring of the cleaning bucket, and tightens the rope 4 (this can be done manually). Figure 9 As shown, the elastic membrane 74 is tightly wrapped around the cylindrical float of the buoy 9. Next, the drive mechanism drives the cleaning tank to rotate reciprocally relative to the connecting base 8, while the connecting base 8 above the cleaning tank and the bottom ring (including the bottom ring shell 73 and the elastic membrane 74) below the cleaning tank remain stationary. The rotating interface between the cleaning tank and the bottom ring is a sealed interface, and the cylindrical float of the buoy 9 is integrated with the bottom ring. The connecting base 8 is integrated with the lifting mechanism. During the rotation of the cleaning tank, cleaning water and detergent can be sprayed into the inner side of the tank shell 70. The first cleaning structure inside the tank shell 70 can simultaneously spray water to clean the cylindrical float of the buoy 9 and the upper support structure.

[0037] In the initial stage of cleaning, the tub shell 70 is empty. During the cleaning process, the nozzle sprays enough cleaning water. After a large amount of cleaning water is sprayed in, the cleaning tub is filled with a large amount of cleaning water. The rotation of the cleaning tub drives the cleaning water to flow and scour inside the tub, creating a cleaning effect similar to that of a washing machine.

[0038] Its beneficial effects include the ability to clean the surface of the marine buoy 9. The main pollutants on marine buoys include bird droppings, which have strong adhesion and severely affect the buoy's color vibrancy, operational efficiency, and solar charging efficiency. The device in this embodiment can clean the buoy 9 effectively. Firstly, the combination of high-pressure jet rinsing and washing machine-style water flow ensures rinsing quality; secondly, the use of a special bucket-type rinsing mode avoids the direct discharge of detergent-containing rinsing water into the marine environment, thus having significant environmental benefits.

[0039] Its ingenious design utilizes a combination of an elastic membrane and a tightening rope, allowing the cleaning tub to fit snugly against buoys of different sizes, forming a washing machine-like inner drum structure. This collects and holds the rinsing water, improving the cleaning compatibility, adaptability, and cleaning capacity, enhancing the cleaning effect, and ensuring the recovery of detergent-containing rinsing water during the cleaning process. The device uses a drive mechanism to rotate the cleaning tub, achieving automated cleaning, significantly improving cleaning efficiency and reducing the labor intensity and risks associated with manual cleaning. The device maintains a closed-loop circulation of rinsing water during the cleaning process, preventing detergent-containing rinsing water from being directly discharged into the marine environment, which is of great significance for protecting the marine ecosystem.

[0040] Furthermore, the drive mechanism includes a gear ring 20, a gear 21, and a drive motor 22, as detailed in [reference needed]. Figure 4 and Figure 6 A gear ring 20 is fixedly mounted on the outer periphery of the connecting base 8; a gear 21 is mounted on the cleaning tub and meshes with the gear ring 20; a drive motor 22 is mounted on the connecting base 8 and connected to and drives the gear 21 to rotate via a drive shaft 23. When the drive motor 22 rotates, it drives the gear 21 to rotate, and the gear 21 meshes with the gear ring 20, thus the gear 21 will rotate around the gear ring 20, and at the same time, the gear 21 will also rotate on its own axis. To improve the stability of the structure, multiple sets of gears 21 can be installed on the cleaning tub to mesh with the gear ring 20, such as... Figure 10 As shown, three sets of meshing gear transmission structures are arranged at equal intervals around the circumference. Simultaneously, a circumferential groove is provided on the outer circumference of the connecting base 8, and the barrel shell 70 slides and engages with this groove, thus forming a rotational fit with the connecting base 8. Through the combined action of the rotational fit and gear meshing, the rotational stability between the connecting base 8 and the barrel shell 70 is improved, making the cleaning process of the buoy 9 more stable and reliable.

[0041] This embodiment can be referred to. Figure 2-4 and Figure 7The drive shaft 23 is set along the first reinforcing structure 71 and extends into the bottom of the cleaning tank; the bottom of the cleaning tank is also provided with a second cleaning structure, which is also driven by the drive shaft 23, including a cleaning ring 50, a driven shaft 51 and a cleaning roller 52; the cleaning ring 50 is fixedly connected to the part of the bottom of the first reinforcing structure 71 that extends beyond the cleaning tank, and a notch is provided on the first reinforcing structure 71. The driven shaft 51 is rotatably set at the notch and is tangential to the cleaning ring 50. The drive shaft 23 contacts the driven shaft 51 and transmits power. Here, a worm gear can be used to realize the vertical transmission between the two shafts. The cleaning roller 52 is sleeved on the driven shaft 51.

[0042] In the above embodiments, the working process is mainly as follows: Before officially cleaning buoy 9 using the first cleaning structure, buoy 9 is first covered with a cleaning device. The second cleaning structure at the bottom of the cleaning device is located on the outer periphery of the cylindrical float of buoy 9. By adjusting the lifting range of the crane for the cleaning device, the height range of the second cleaning structure on the outer periphery of the cylindrical float of buoy 9 can be adjusted. When the second cleaning structure is working, the drive shaft 23 rotates, driving the driven shaft 51 on the second cleaning structure, which in turn drives the cleaning roller 52 on the driven shaft 51 to rotate. The cleaning roller 52 contacts the outer periphery of the cylindrical float of buoy 9, wiping and cleaning the surface of the buoy. By adjusting the height range of the second cleaning structure on the outer periphery of the cylindrical float, cleaning can be performed on different height areas. It can also be inserted underwater to clean barnacles and other objects below the waterline. At the same time, due to the rotation of the cleaning tank, the cleaning roller 52 will also rotate around the outer periphery of the cylindrical float of buoy 9. During this process, the tightening rope is not tightened. Through the coordination of lifting and rotating, a comprehensive cleaning of the outer periphery of the float can be achieved. In particular, the part below the waterline can be cleaned.

[0043] Generally, bird droppings tend to accumulate on the upper surface and frame structure of buoy 9, while marine organisms, especially those below the waterline, are more likely to adhere to the outer circumference of the buoy body. Barnacles and other marine life can thrive there, potentially damaging the buoy's coating and affecting its corrosion resistance in seawater. Furthermore, in the above embodiment, the elastic membrane 74 may not adhere completely to the circumferential surface of the buoy body, leading to leakage of cleaning water from the cleaning tank.

[0044] After setting up the second cleaning structure, before officially using the first cleaning structure to clean the buoy 9, the circumferential surface of the buoy 9 is cleaned first. On the one hand, this can remove the attached organisms on the surface, and on the other hand, it can ensure that the buoy surface is clean and flat, so that the elastic membrane 74 can adhere more tightly to the circumferential surface of the buoy 9. This way, when the washing water is injected into the cleaning tank for cleaning, it can prevent a large amount of washing water containing detergent from leaking into the marine environment.

[0045] Furthermore, such as Figure 7As shown, the cleaning roller 52 includes an inner ring 521, an outer ring 522, connecting posts 523, and pressure sensors; the inner diameter of the inner ring 521 is fixedly fitted with the driven shaft 51, multiple connecting posts 523 are connected between the outer circular surface of the inner ring 521 and the inner circular surface of the outer ring 522, and multiple pressure sensors are disposed on the outer circular surface of the inner ring 521. The outer ring 522 is made of a cleaning friction material, such as sponge, and the connecting column 523 is made of a material that deforms under pressure and can recover, such as a rubber column or plastic column. When the outer ring 522 is squeezed, the outer ring 522 and the connecting column 523 deform, squeezing the inner ring 521. The inner circular surface of the outer ring 522 presses against the pressure sensor on the outer circular surface of the inner ring 521. During the cleaning process, the cleanliness of the cleaning area can be determined by reading the data from the pressure sensor. The specific principle is as follows: Pressure sensors are set around the circumference of the cleaning roller 52. When the cleaning roller 52 rotates and contacts the buoy surface, the readings of the pressure sensors on the cleaning roller 52 can be measured in advance when the buoy surface is clean and flat, and the readings of multiple sensors around the circumference are relatively consistent. When there are barnacles or other debris on the buoy surface, the pressure readings detected by the pressure sensors as they pass over the buoy surface will show differences, indicating that the area needs to be cleaned. The cleaning is completed when the pressure sensor readings return to the predicted readings. The height of the cleaning roller 52 on the buoy shell surface can be changed (adjusted by a crane) to move the cleaning area up or down.

[0046] For this embodiment, please refer to Figure 8 The first cleaning structure includes a clamping plate 60 and a nozzle assembly 61 along the first reinforcing structure 71; the two clamping plates 60 protrude from the inside of the barrel shell 70, and the nozzle assembly 61 is located between the two clamping plates 60, facing the central area of ​​the barrel shell 70.

[0047] Before cleaning begins, the elastic membrane 74 is attached to the circumferential surface of the buoy 9, forming a flushing water receiving area with the barrel shell 70. During cleaning, high-pressure water containing detergent is first sprayed through the nozzle assembly 61 to flush the buoy using a high-pressure water jet. Simultaneously, flushing water accumulates inside the barrel shell 70. Once there is enough water in the barrel, the nozzle assembly 61 is turned off. The motor is then turned on to drive the barrel shell 70 to rotate back and forth, for example, rotating 30 degrees clockwise and then 30 degrees counterclockwise, alternating in this manner. Utilizing the water-blocking effect of the internal clamp 60, the flushing water inside the barrel flows back and forth, rinsing the surface of the buoy. Through both high-pressure water jet flushing and internal water flow rinsing, bird droppings and other dirt on the buoy are powerfully cleaned.

[0048] After cleaning, the cleaning water inside the tank 70 is pumped out to prevent the direct discharge of cleaning water containing detergent into the marine environment. Meanwhile, considering that cleaning requires fresh water, recycling the cleaning water allows for reuse, enabling the use of fresh water resources carried on a single voyage to clean more buoys and improve the efficiency of the work vessel.

[0049] Furthermore, such as Figure 8 As shown, the first cleaning structure also includes a cleaning rod 62 along the first reinforcing structure 71. The cleaning structure on the cleaning rod 62 is the same as that on the cleaning roller 52, that is, it includes an inner ring, an outer ring, a connecting column, and a pressure sensor. However, functionally, the pressure sensor on the cleaning roller 52 is used to detect the degree of cleanliness, while here, the pressure sensor on the cleaning rod 62 is used to detect the degree of contact between the cleaning rod 62 and the buoy structure.

[0050] The cleaning rod 62 is connected to the inside of the tank shell 70 at both ends via two telescopic members 63. Fixed to the tank shell 70, the cleaning rod 62 rotates around the buoy along with the tank shell 70. The cleaning rod 62 can wipe the buoy and agitate the cleaning water inside the tank shell 70. The two telescopic members 63 can adjust the tilt angle of the cleaning rod 62, allowing it to adapt to the support structure of the buoy 9 for different buoy models (generally conical or with a constant cross-section). A pressure sensor detects the contact between the cleaning rod 62 and the buoy, ensuring that the cleaning rod 62 brushes the structure of the buoy 9 without colliding with it. This embodiment, in addition to the high-pressure water jet rinsing and tank water flow rinsing modes, also includes a wiping cleaning mode, which increases cleaning power and ensures thorough cleaning, especially effective for cleaning the solar panels on the buoy.

[0051] For this embodiment, please refer to Figure 4 , Figure 7 and Figure 9 Two pull rope devices 3 are provided between the bottom ring shell 73 and the elastic membrane 74, respectively connected to the two ends of the tightening rope 4 and capable of tightening it. The tightening rope 4 is wound more than one turn between the bottom ring shell 73 and the elastic membrane 74 to ensure the tightening effect of the tightening rope 4 on the elastic membrane 74. The pull rope device 3 can be a telescopic structure, such as a telescopic cylinder. When retracted, it tightens the tightening rope 4, making the elastic membrane 74 fit tightly against the circumference of the buoy to form a sealed interface. When extended, it releases the tightening rope 4, allowing the elastic membrane 74 to return to its original position. Figure 5 The tension shown ( Figure 5 The elastic membrane 74(B) is in the state shown, which facilitates the detachment of the cleaning device from the buoy.

[0052] Please refer to this embodiment. Figure 1 and Figure 2 A type of in-situ cleaning vessel for marine buoy 9 is described. The cleaning vessel can be a buoy operation vessel, a buoy inspection vessel, or other similar vessel, serving merely as a carrier for the cleaning device. Any vessel can be used as a cleaning vessel after being equipped with the cleaning device. The cleaning vessel includes a hull 10, a lifting mechanism 11, a telescopic mechanism 12, and the aforementioned in-situ cleaning device for marine buoy 9. The lifting mechanism 11 is installed on the hull 10, and the telescopic mechanism 12 is fixedly installed at the end of the boom of the lifting mechanism 11. The connecting base 8 of an in-situ cleaning device for marine buoy 9 is fixedly connected to the telescopic end of the telescopic mechanism 12.

[0053] Before buoy cleaning operations, the work vessel is positioned around the buoy, and the cleaning device is lifted using the lifting mechanism 11 and placed over the buoy from above for cleaning. After cleaning, the cleaning device is removed, and the work vessel moves on to the next buoy for cleaning.

[0054] This embodiment describes an in-situ cleaning method for a marine buoy 9, employing the aforementioned in-situ cleaning vessel for marine buoy 9, and includes the following steps: The in-situ cleaning vessel for buoy 9 approaches the target buoy 9. Adjust the angle and height of the lifting mechanism 11, and cover the buoy 9 with the in-situ cleaning device from top to bottom; Cleaning near the water level of buoy 9: Drive motor 22 drives driven shaft 51 to rotate, driven shaft 51 drives barrel shell 70 and cleaning roller 52 to rotate, barrel shell 70 rotates around the outer circumference of buoy 9, cleaning roller 52 rotates around its own axis and contacts the outer circumference of buoy 9, telescopic mechanism 12 adjusts the height of cleaning roller 52 along the axis of buoy 9; Cleaning the upper surface of buoy 9: The rope puller 3 pulls the tightening rope 4, and the tightening rope 4 tightly binds the elastic membrane 74 to the outer periphery of buoy 9 to form a sealed interface. The drive motor 22 drives the driven shaft 51 to rotate, and the driven shaft 51 drives the barrel shell 70 and the cleaning rod 62 to rotate. The nozzle group 61 sprays out cleaning water. After cleaning is completed, the cleaning water in the cleaning barrel is extracted. The drive motor 22 stops working, the rope puller 3 loosens the tightening rope 4, the elastic membrane 74 rebounds and detaches from the outer shell of the buoy 9, and the lifting mechanism 11 lifts the marine buoy 9 and the in-situ cleaning device detaches from the buoy 9.

[0055] This embodiment of the in-situ buoy cleaning method achieves comprehensive and efficient cleaning of buoys using a specialized cleaning vessel and equipment. The method is simple to operate and yields excellent cleaning results. Simultaneously, the use of an elastic membrane to form a sealed interface effectively prevents cleaning water leakage, protecting the marine environment. After cleaning, the cleaning equipment can be easily detached from the buoy without affecting its normal use, demonstrating significant benefits.

[0056] In summary, the present invention effectively overcomes the various shortcomings of the prior art, produces beneficial technical effects, and has made significant progress.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention.
