Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0032] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0033] See also Figure 1-Figure 11 , the present invention provides an embodiment of an offshore buoy in-situ cleaning device, a cleaning ship and a cleaning method.

[0034] Among them, an in-situ cleaning device for a marine buoy 9 is used to cover and clean the buoy 9 from top to bottom, including a connecting base 8, a cleaning bucket and a tightening rope 4; The cleaning bucket is rotatably connected to the lower side of the connection base 8, and can be driven by a driving mechanism to rotate relative to the connection base 8. The cleaning bucket has no bottom, so it can cover the buoy 9 like a hat; The barrel shell 70 of the cleaning barrel is provided with a first reinforcement structure 71 and a second reinforcement structure 72 along the generatrix and the circumferential direction, respectively. The first cleaning structure is provided inside the barrel shell 70. The bottom of the barrel shell 70 is rotatably mounted with a barrel bottom ring. The barrel shell 70 and the barrel bottom ring can also rotate with each other. In order to realize the mutual rotation, the bottom ring shell 73 is mounted on the barrel shell 70 through a sliding clamping structure. Figure 7 In the left side section, the sliding snap-fit ​​structure includes protrusions and grooves respectively located on the bottom ring shell 73 and the barrel shell 70 and matching each other, and a sealing strip should be set 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 elastic membrane 74 faces the inner buoy 9. The top of the bottom ring shell 73 is slidably connected to the barrel shell 70, and the contact part between the outer side of the bottom ring shell 73 and the barrel shell 70 and its reinforcement structure is also in a sliding relationship. The inner side of the bottom ring shell 73 is provided with an elastic membrane 74, and the tightening rope 4 is located between the elastic membrane 74 and the bottom ring shell 73; The tightening rope 4 is arranged between the bottom ring shell 73 and the elastic membrane 74. The winding amount of the tightening rope 4 should be greater than one circle. After the cleaning bucket covers the buoy 9, the tightening rope 4 is tightened from both ends, and the elastic membrane 74 will be tied to the outer periphery of the buoy 9. Figure 2-Figure 5 As shown, Figure 5 The dotted part shows the initial state, at which time the cleaning device is not yet connected to the buoy 9, and the specific situation of the barrel bottom ring is: the tightening rope 4 (B) is not tightened, and the elastic membrane 74 (B) is in a retracted and tightened state; once the cleaning device covers the buoy 9, the connection begins, specifically: the tightening rope 4 (A) is tightened, and the tightening rope simultaneously pulls the elastic membrane 74 (A) tightly against the outer periphery of the buoy 9. The elastic membrane 74 can be a rubber membrane. Once it is tightly attached to the outer periphery of the buoy 9, a sealing interface is formed, so that the barrel shell 70 can contain cleaning water without leaking from the barrel bottom ring.

[0035] In order to recycle the washing water in the washing bucket after washing, a water extraction pipe needs to be set in the bucket. The water pipe can be made of a soft pipe, and a redundant length should be set to adapt to a certain degree of barrel twisting. The water pipe of the nozzle group 61 can be reused, for example, a one-way valve is set at the end of the water pipe, such as Figure 4 and Figure 8 As shown, when flushing with water, the one-way valve 610 is closed so that the flushing water cannot flow out from the end of the water pipe, but can only be sprayed out from the nozzle group 61; when the flushing water is pumped out, the one-way valve 610 is opened, and the flushing water is pumped out of the barrel. The nozzle can use a one-way nozzle with a one-way valve to prevent unexpected backflow of the flushing water during the flushing process.

[0036] The main working process of the above embodiment is as follows: The cleaning device is set on the working ship through the crane, and the connecting base 8 is connected and fixed to the crane as the body of the cleaning device. When the buoy 9 is cleaned, the cleaning device covers the buoy 9 from top to bottom, and then the bottom circle of the cleaning barrel is tightened, and the tightening rope 4 is tightened (which can be done manually). Fig. 9 As shown, the elastic membrane 74 is tightly wound around the cylindrical floating body of the buoy 9. Then, the driving mechanism drives the cleaning barrel to reciprocate relative to the connecting base 8, while the connecting base 8 located above the cleaning barrel and the barrel bottom ring (including the bottom ring shell 73 and the elastic membrane 74) located below the cleaning barrel remain stationary. The rotation interface between the cleaning barrel and the barrel bottom ring is a sealing interface. The cylindrical floating body of the buoy 9 is connected to the barrel bottom ring as a whole, and the connecting base 8 is connected to the lifting mechanism as a whole. During the rotation of the cleaning barrel, cleaning water and detergent can be sprayed into the inner side of the barrel shell 70, and the first cleaning structure inside the barrel shell 70 can spray water to clean the cylindrical floating body of the buoy 9 and the upper support structure at the same time.

[0037] At the beginning of cleaning, the barrel shell 70 is empty. During the cleaning process, the nozzle uses high-pressure water to clean. After enough cleaning water is sprayed in, a large amount of cleaning water is filled into the cleaning barrel. The rotation of the cleaning barrel drives the cleaning water to flush and flow in the cleaning barrel, forming a cleaning effect like a washing machine.

[0038] Its beneficial effects include: being able to clean the surface of the offshore buoy 9. The main pollutants of the offshore buoy include substances such as bird droppings, which have strong adhesion and have a serious impact on the color clarity, working efficiency and solar charging efficiency of the buoy. The device of this embodiment can clean the buoy 9 and has a good cleaning effect. On the one hand, the combination of high-pressure spray flushing and washing machine-style water flow flushing can ensure the flushing quality; on the other hand, the use of a special barrel flushing mode can prevent the flushing water containing detergent from being directly discharged into the marine environment, which has good environmental protection significance.

[0039] Its design cleverly utilizes the combination of elastic membrane and tightening rope, so that the washing barrel can fit closely to buoys of different sizes, forming the inner drum structure of the washing machine, which can collect and hold the flushing water, improve the compatibility, adaptability and cleaning ability of the washing, enhance the cleaning effect, and ensure the recovery of the washing water containing detergent during the cleaning process. The device drives the washing barrel to rotate through the driving mechanism, realizes automatic cleaning, greatly improves the cleaning efficiency, and reduces the labor intensity and risk of manual cleaning. The device can maintain a closed circulation of the washing water during the cleaning process, avoiding the direct discharge of the flushing water containing detergent into the marine environment, which is of great significance to the protection of the marine ecological environment.

[0040] Furthermore, the driving mechanism includes a gear ring 20, a gear 21 and a driving motor 22, which can be seen in Figure 4 and Figure 6 ; The ring gear 20 is fixedly arranged on the outer periphery of the connection base 8; the gear 21 is installed on the cleaning bucket and meshes with the ring gear 20; the driving motor 22 is installed on the connection base 8 and is connected to and drives the gear 21 to rotate through the driving shaft 23. When the driving motor 22 rotates, it drives the gear 21 to rotate, and the gear 21 meshes with the ring gear 20, so that the gear 21 will rotate around the ring gear 20, and the gear 21 will also rotate on its own. In order to improve the stability of the structure, multiple sets of gears 21 can be arranged on the cleaning bucket to mesh with the ring gear 20, such as Fig.10 As shown, three groups of meshing gear transmission structures are arranged at equal intervals on the circumference. At the same time, a circumferential groove is also arranged on the outer circumference of the connection base 8, and the barrel shell 70 is slidably engaged with the groove, thereby forming a rotational fit with the connection base 8. Through the combined effect of rotational fit and gear meshing, the rotational stability between the connection 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 found in Figure 2-4 and Figure 7The driving shaft 23 is arranged along the first reinforcement structure 71 and extends into the bottom of the cleaning barrel; a second cleaning structure is also arranged at the bottom of the cleaning barrel, and the second cleaning structure is also driven by the driving 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 bottom of the first reinforcement structure 71 and extends beyond the cleaning barrel. A notch is arranged on the first reinforcement structure 71, and the driven shaft 51 is rotatably arranged at the notch and tangentially along the cleaning ring 50. The driving shaft 23 contacts the driven shaft 51 and transmits power. A worm gear can be used here to realize vertical transmission of the two shafts, and the cleaning roller 52 is sleeved on the driven shaft 51.

[0042] In the above embodiment, the working process is mainly as follows: Before the first cleaning structure is used to clean the buoy 9, the buoy 9 is first covered with a cleaning device. The second cleaning structure at the bottom of the cleaning device is located at the outer periphery of the cylindrical buoy of the buoy 9. By adjusting the lifting range of the cleaning device height of the crane, the height range of the second cleaning structure at the outer periphery of the cylindrical buoy of the buoy 9 can be adjusted. When the second cleaning structure is working, the driving shaft 23 rotates to drive the driven shaft 51 on the second cleaning structure, thereby driving the cleaning roller 52 on the driven shaft 51 to rotate. The cleaning roller 52 contacts the outer periphery of the cylindrical buoy of the buoy 9, and the surface of the buoy can be wiped and cleaned. By adjusting the height range of the second cleaning structure at the outer periphery of the cylindrical buoy, different height areas can be cleaned, and it can also be inserted underwater to clean barnacles and the like below the water level line; at the same time, due to the rotation of the cleaning barrel, the cleaning roller 52 will also rotate around the outer periphery of the cylindrical buoy of the buoy 9, and the tightening rope is not tightened in this process. Through the coordination of lifting and rotating, the outer periphery of the buoy can be fully cleaned. In particular, the part below the water level line can be cleaned.

[0043] Generally speaking, bird droppings are easily accumulated on the upper surface and frame structure of the buoy 9, and marine organisms are more easily attached to the outer diameter of the buoy 9, especially the part below the water level, which often breeds barnacles, etc., which may damage the coating on the surface of the buoy and affect the corrosion resistance of the buoy in seawater. On the other hand, it may also lead to the situation in the above embodiment that when the elastic membrane 74 is attached to the circumferential surface of the buoy 9, it cannot be completely attached, thereby causing the cleaning water in the cleaning bucket to leak.

[0044] After the second cleaning structure is set up, before the first cleaning structure is used to clean the buoy 9, the circumferential surface of the buoy 9 is cleaned first. On the one hand, it can clean 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 be more closely attached to the circumferential surface of the buoy 9. In this way, when washing water is injected into the cleaning bucket for cleaning, a large amount of washing water containing detergent can be prevented from leaking into the marine environment.

[0045] Furthermore, if Figure 7As shown, the cleaning roller 52 includes an inner ring 521, an outer ring 522, a connecting column 523 and a pressure sensor; the inner diameter of the inner ring 521 is fixedly matched with the driven shaft 51, a plurality of connecting columns 523 are connected between the outer circumferential surface of the inner ring 521 and the inner circumferential surface of the outer ring 522, and a plurality of pressure sensors are arranged on the outer circumferential surface of the inner ring 521; The outer ring 522 is a cleaning friction material, such as a sponge, and the connecting column 523 is a material that is deformed under force and can recover, such as a rubber column or a plastic column. When the outer ring 522 is squeezed, the outer ring 522 and the connecting column 523 are deformed, squeezing the inner ring 521, and the inner surface of the outer ring 522 squeezes the pressure sensor on the outer surface of the inner ring 521. During the cleaning process, the cleanliness of the cleaning area can be known by reading the data of the pressure sensor. The specific principle is as follows: a pressure sensor is set on the circumference of the cleaning roller 52. When the cleaning roller 52 rotates and contacts the buoy surface, when the buoy surface is clean and flat, the reading of the pressure sensor on the cleaning roller 52 can be measured in advance, and the readings of multiple sensors on the circumference are relatively consistent. When there are barnacles or other debris on the buoy surface, the pressure reading detected by the pressure sensor when passing the buoy surface will be different, indicating that the area needs to be cleaned, until the pressure sensor reading returns to the predicted reading, which means that the cleaning has been completed. The height of the cleaning roller 52 on the surface of the buoy shell can be changed (adjusted by the crane) to move the cleaning area up or down.

[0046] For this example, please refer to Figure 8 The first cleaning structure includes a clamping plate 60 and a nozzle group 61 along the first reinforcement structure 71; the two clamping plates 60 protrude from the inner side of the barrel shell 70, and the nozzle group 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 float 9, and cooperates with the barrel shell 70 to form a flushing water receiving area. During cleaning, high-pressure water containing detergent is first sprayed through the nozzle group 61 to flush the float in the form of a high-pressure water column flushing. At the same time, flushing water is accumulated in the barrel shell 70. After there is enough water in the barrel, the nozzle group 61 is closed. The motor is turned on to drive the barrel shell 70 to reciprocate, for example, rotating 30 degrees forward and then 30 degrees reverse, and so on alternately. The water-blocking effect of the clamping plate 60 in the barrel is used to drive the flushing water in the barrel to flow back and forth to flush the surface of the float. Through the two modes of high-pressure water column flushing and water flow flushing in the barrel, the bird droppings and other dirt on the float are strongly cleaned.

[0048] After cleaning is completed, the cleaning water in the barrel shell 70 is pumped out to avoid directly discharging the cleaning water containing detergent into the marine environment. At the same time, considering that fresh water is needed for cleaning, the recycling of the cleaning water can make it reused, and the fresh water resources carried by the sea at one time can clean more buoys, thereby improving the operating efficiency of the operating ship.

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

[0050] The two ends of the cleaning rod 62 are connected to the inner side of the barrel shell 70 through two telescopic parts 63 respectively. The cleaning rod 62 is fixed to the barrel shell 70 and will rotate around the buoy with the barrel shell 70. The cleaning rod 62 can wipe the buoy and stir the cleaning water in the barrel shell 70. The two telescopic parts 63 can adjust the inclination angle of the cleaning rod 62. For different buoy models (generally conical or equal cross-sectional shapes), the cleaning rod 62 can be adapted to the bracket structure of the buoy 9. The pressure sensor can sense the contact between the cleaning rod 62 and the buoy, so that the cleaning rod 62 can brush the buoy 9 structure without colliding with the buoy 9 structure. In addition to the two modes of high-pressure water column flushing and water flow flushing in the barrel, this embodiment also adds a wiping cleaning mode, which can increase the cleaning ability and ensure clean cleaning, especially for the solar panels on the buoy. There is a higher cleaning effect.

[0051] For this example, please refer to Figure 4 , Figure 7 and Fig. 9 A rope puller 3 is also provided between the bottom ring shell 73 and the elastic membrane 74. There are two rope pullers 3, which are respectively connected to the two ends of the tightening rope 4 and can be tightened. The winding range of the tightening rope 4 between the bottom ring shell 73 and the elastic membrane 74 is greater than one circle to ensure the tightening effect of the tightening rope 4 on the elastic membrane 74. The rope puller 3 can be a telescopic structure, such as a telescopic cylinder. When retracting, the tightening rope 4 is tightened to make the elastic membrane 74 close to the circumference of the buoy to form a sealing interface. When extending, the tightening rope 4 is loosened to allow the elastic membrane 74 to return to the original state. Figure 5 The tension state shown ( Figure 5 The state shown in the middle elastic membrane 74 (B) facilitates the detachment of the cleaning device from the buoy.

[0052] For this example, please refer to Figure 1 and Figure 2 , an in-situ cleaning ship for a marine buoy 9, the cleaning ship can be a buoy operation ship, a buoy inspection ship or other ships, which is only used as a carrier of the cleaning device, and any ship can be used as a cleaning ship after the cleaning device is installed. The cleaning ship includes a hull 10, a lifting mechanism 11, a telescopic mechanism 12 and an in-situ cleaning device for a marine buoy 9 as described above; The lifting mechanism 11 is installed on the hull 10 , the telescopic mechanism 12 is fixedly arranged at the end of the boom of the lifting mechanism 11 , and a connecting base 8 of an in-situ cleaning device for an offshore buoy 9 is fixedly connected to the telescopic end of the telescopic mechanism 12 .

[0053] Before the buoy cleaning operation, the operating boat is driven around the buoy, the cleaning device is lifted by the hoisting mechanism 11, and the buoy is covered from top to bottom, and then the cleaning work is carried out. After the cleaning is completed, the cleaning device is lifted off, and the operating boat is driven to clean the next buoy.
