[0028] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] See also Figures 1 to 10 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. 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.

[0030] 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.

[0031] See also Figure 1-10 , an embodiment of the buoy automatic spraying device and method provided by the present invention.

[0032] Among them, the buoy automatic spraying device includes: A carrier assembly and a first spray assembly 2 and a second spray assembly 3 respectively arranged on both sides of the buoy, wherein the first spray assembly 2 and the second spray assembly 3 are fixedly mounted on the carrier assembly; See also Figure 2, the carrying assembly includes a first supporting platform 10 and a second supporting platform 11, which support and drive the buoy to rotate along its own axis. The carrying assembly is generally a special transport flat car for navigation marks, which includes a vehicle body, a front jacking structure (first supporting platform) and a rear jacking mechanism (second supporting platform). Along the length direction of the vehicle body, the front jacking structure and the rear jacking mechanism are respectively arranged on the upper surface of the vehicle body to support the navigation mark; the lower surface of the vehicle body is provided with a walking mechanism, which is used to drive the vehicle body to move. Considering the actual shape of the navigation mark, the first supporting platform 10 is arranged in the middle of one end of the vehicle body, and the navigation mark is supported by an arc-shaped supporting surface formed by a plurality of roller arrays. The second supporting platform 11 is arranged on both sides of the other end of the vehicle body, and rollers are used to support the navigation mark. When the rollers and the rollers rotate, the navigation mark can be rotated along its own axis; See also Figure 1 , the first spraying assembly 2 includes a first paint tube 20 and a first nozzle 21. The first paint tube 20 matches the direction of the busbar of the buoy. The first paint tube 20 needs to be provided with a corresponding supporting and fixing structure. Since the specific supporting and fixing method can be set arbitrarily, it is not illustrated in the figure. A plurality of first nozzles 21 are arranged in an array along the first paint tube 20. The first nozzle 21 is connected to the first paint tube 20, and the first paint tube 20 faces the surface of the buoy. The shape of the navigation mark / buoy is a cylindrical rotating structure. The busbar of the buoy refers to the edge line that can be rotated around the axis to form a cylindrical rotating structure. The first paint tube 20 matches the direction of the busbar of the buoy, but it is not required to be completely consistent. As long as the direction of the first paint tube 20 and the busbar of the buoy are roughly consistent, a corresponding distance should be maintained at the same time, so that during the rotation of the navigation mark / buoy, the protective paint of the first paint tube 20 can be evenly sprayed onto the surface of the buoy; See also Figure 5 The second spraying assembly 3 includes a storage bin 30 and a second nozzle 31. The storage bin 30 is a shell structure and also matches the direction of the busbar of the buoy. The storage bin 30 is provided with a penetrating sliding groove. The direction of the sliding groove matches the direction of the busbar of the buoy, and the penetrating direction points to the surface of the buoy. The second nozzle 31 is slidably installed in the sliding groove. The storage bin 30 also needs to be provided with a corresponding supporting and fixing structure to fix it on the transfer platform. When the second nozzle 31 slides along the sliding groove, an area can be sprayed on the surface of the buoy in the length direction along the busbar of the buoy; if the second nozzle 31 remains stationary and the buoy rotates, a circular area can be sprayed in the circumferential direction of the buoy. Through the cooperation of the two, the surface of the buoy can be sprayed full.

[0033] In the above embodiment, the first spraying assembly and the second spraying assembly can spray different types of coatings, for example, the first spraying assembly sprays the bottom ordinary coating, and the second spraying assembly is used to spray the outer special coating with seawater anti-corrosion performance, especially the underwater paint that can inhibit the attachment of marine organisms. Considering the performance characteristics of the outer special coating, the spraying difficulty and technicality are higher, and the second nozzle 31 of the second spraying assembly can be operated by a technician. Specifically, the technician can control the spraying position and spraying amount of the special coating by controlling the sliding speed of the second nozzle 31 along the sliding groove and / or the rotation speed of the buoy, thereby achieving higher quality and more flexible spraying, and improving the flexibility and adaptability of spraying. The combination of automation and manual work solves the problems in the prior art that manual spraying operations are difficult to complete continuously and the spraying quality is difficult to control, significantly improves the anti-corrosion performance of the buoy, and achieves a balance between the labor intensity of the operators and the spraying quality of the buoy coating.

[0034] For this example, please refer to Figure 3-4 , the second spraying assembly 3 further includes a slip ring 32, a flexible membrane 33 and a longitudinal skeleton 34; Two slip rings 32 are detachably arranged at both ends of the buoy. When the buoy rotates, the slip rings 32 rotate with the buoy. The inner ring of the slip ring 32 matches the outer diameter of the buoy, and a limited sliding groove is arranged on the outer ring. The slip ring 32 can be formed by splicing multiple arc sections. The inner surface of the slip ring 32 is magnetic, so that the slip ring 32 can be easily installed on the buoy or removed from the buoy. The upper and lower sides of the accommodating chamber 30 along the circumferential direction of the buoy are open, the upper side forms a first cavity 302, and the lower side forms a second cavity 303; the longitudinal skeleton 34 includes a connecting rod 341 and a contact block 342, the connecting rod 341 matches the direction of the busbar of the buoy, and the two contact blocks 342 are respectively fixed at the two ends of the connecting rod 341, and the contact blocks 342 at the two ends are respectively slidably matched with the limiting slide grooves of the two slip rings 32, and the shape of the matching area can be set to a "T" shape to ensure sliding while preventing it from falling out of the slide groove; There are multiple groups of longitudinal skeletons 34, and the flexible membrane 33 is connected between the multiple groups of longitudinal skeletons 34. Initially, the flexible membrane 33 is folded, and the flexible membrane 33 and the multiple groups of longitudinal skeletons 34 are all stored in the first cavity 302; when working, the multiple groups of longitudinal skeletons 34 are unfolded from the first cavity 302 along the circular array of the buoy and connected to the second cavity 303, and fixed to the second cavity 303, and the flexible membrane 33 wraps the buoy spray section.

[0035] During the spraying process, the buoy rotates, and the multiple sets of longitudinal frames 34 and flexible membranes 33 wrap around the spraying operation area of ​​the buoy like a lantern. Since the longitudinal frames 34 and the slip rings 32 at both ends of the buoy are in sliding cooperation, the longitudinal frames 34 and the flexible membranes 33 do not rotate during the rotation of the buoy. In order to enhance the stability of the lantern structure formed by the longitudinal frames 34 and the flexible membranes 33, multiple circles of annular stirrups can be arranged along the circumference as transverse frames.

[0036] In the above embodiment, through the cleverly designed combination of the longitudinal skeleton and the flexible membrane, the buoy spraying operation area is effectively isolated, the environmental friendliness and safety of the spraying operation are improved, and the paint leakage during the spraying process can be reduced. Especially when the second spraying component sprays the outer layer of special coating, it can prevent the coating containing special anti-marine biological growth ingredients from drifting out of the operation area, thereby effectively protecting the health of the operators and reducing the risk of environmental pollution.

[0037] For this example, please refer to Figure 2-6 The upper end surface of the sliding groove is provided with an upper sealing film 3011, and the lower end surface of the sliding groove is provided with a lower sealing film 3012. The upper sealing film 3011 and the lower sealing film 3012 are connected as a whole through a magnetic strip 3013. The second nozzle 31 includes a sliding body 310 and a spray gun 312. The upper and lower ends of the sliding body 310 are respectively slidably matched with the upper and lower end surfaces of the sliding groove. The sliding interface is located on the inner side of the sealing film. The spray gun 312 penetrates the sliding body 310, and the spray port of the spray gun 312 faces the surface of the buoy. Figure 7 As shown, the upper and lower ends of the sliding body 310 are set to be cylindrical, and the cylindrical shape is slidably matched with the grooves on the upper and lower end surfaces of the sliding groove, thereby ensuring that the sliding body 310 can move along the buoy generatrix; On the sliding body 310, at the place where it cooperates with the sealing film, pointed portions 3101 are provided on both sides of the sliding direction. When the sliding body 310 slides along the sliding groove, the pointed portions 3101 separate the magnetic strip 3013 between the upper sealing film 3011 and the lower sealing film 3012. The magnetic strip 3013 is flexible, and the pointed portion 3101 cannot be made of materials with magnetic attraction. When the sliding body 310 slides away, the upper sealing film 3011 and the lower sealing film 3012 in the corresponding area automatically restore into one body under the action of the magnetic strip 3013 and close the sliding groove.

[0038] In the above embodiment, the upper sealing film 3011 and the lower sealing film 3012 are cleverly designed with the magnetic strip 3013, which not only realizes the tight closure of the sliding groove and the sliding of the sliding body 310, but also greatly improves the safety and environmental protection of the paint spraying operation. The magnetic force of the magnetic strip 3013 ensures the lasting stability of the sealing effect, and can effectively prevent the paint from leaking from the gap even during the frequent sliding operation of the sliding body 310, thereby avoiding environmental pollution and waste of paint materials. In addition, the operation process is simplified, making the movement of the sliding body 310 in the sliding groove smoother and more unobstructed, further improving the efficiency and quality of the spraying operation.

[0039] For this example, please refer to Figure 7 and Figure 8 A penetrating mounting hole is provided on the sliding body 310, in which a camera 311 is provided in the same direction as the spray gun 312, and the end of the camera 311 does not exceed the surface of the sliding body 310, and the camera 311 faces the surface of the buoy. At a position matching the position of the camera 311, a transparent ring 313 is rotatably provided on the sliding body 310. Figure 7 In the figure, the transparent ring 313 is partially cut to show the positional relationship between the transparent ring 313 and the sliding body 310. A display screen is provided on the upper part of the outer side of the sliding body 310, and the display screen displays the picture taken by the camera 311.

[0040] The above embodiment provides a means of internal visual monitoring during the buoy spraying process by cleverly installing the camera and the transparent ring. The camera is cleverly placed in the sliding body and is isolated by the transparent ring to effectively prevent interference from paint spray. Even if the paint blocks a part of the transparent ring, the camera's viewing angle can be quickly restored by simply rotating the transparent ring to ensure visualization of the spraying operation area.

[0041] This embodiment can be combined with Figure 6 and Figure 7The back of the display screen is provided with a power mechanism, which includes a first power shaft 35, a second power shaft 36 and a third power shaft 37, and at least one power shaft is driven by a power source; a rotationally matched support ring 351 is provided in the middle of each power shaft, and each power shaft is rotationally supported by the support ring 351, and the support ring 351 is connected to the back of the display screen through a telescopic column 352, and the length of the telescopic column 352 can be extended and shortened when under pressure and become longer when there is no pressure. The two ends of each power shaft are connected and synchronized by a friction belt 38, and the friction belt 38 is also in contact with the outer shell of the storage chamber 30. The purpose of this setting is that the distance between the three power shafts and the back of the display screen can be automatically adapted according to the distance between the back of the display screen and the outer shell of the storage chamber 30, so that the friction belt 38 is always attached to the back of the display screen, and when the friction belt 38 rotates, it can move along the sliding groove with the sliding body 310 and the spray gun 312 for automatic spraying.

[0042] As another scheme of the above embodiment, a first fixing ring 3102 is arranged on the outside of the outer side of the sliding body 310, and a second fixing ring is arranged at the tail end of the spray gun 312, and a conical connecting membrane 314 is connected between the first fixing ring 3102 and the second fixing ring; the matching part between the spray gun 312 and the sliding body 310 is a spherical match, and there is friction resistance at the matching interface.

[0043] In the above embodiment, since the spray gun 312 is in a through relationship with the sliding body 310 and the through area is a spherical fit, the spray gun 312 can be deflected at a certain angle relative to the sliding body 310, and the sliding position of the sliding body 310 and the deflection angle of the spray gun 312 can be manually controlled by an experienced operator, and the spraying operation is performed according to the picture feedback of the display screen. Compared with the previous embodiment in which the spray gun angle is fixed and the spray gun sliding position is controlled by the power mechanism, in this embodiment, the spray gun angle can be adjusted and the spray gun sliding position is controlled by the operator, which can achieve a more flexible spraying operation and take into account the spraying quality and spraying efficiency. For example, the first spraying adopts the automatic mode of the previous embodiment, and the second spraying adopts the manual operation mode of this embodiment, and the experienced operator performs additional spraying on the first spraying according to the situation seen on the display screen.

[0044] For this example, please refer to Fig. 9 A partition plate 304 is provided on the side of the receiving chamber 30 facing the buoy, the partition plate 304 extends toward the buoy but does not contact the buoy, and the partition plate 304 is higher than the sliding groove; An air inlet pipe 305 is provided on the side of the containing chamber 30 facing away from the buoy. The air inlet pipe 305 is arranged along the sliding groove and connected to the area between the containing chamber 30 and the buoy through a plurality of tributaries 3051 along the way, and the connecting area is located at the lower side of the partition plate 304; An air outlet pipe 306 is also provided, which is arranged along the air inlet pipe 305 and connected to the area between the containing chamber 30 and the buoy along the way, and the connecting area is located on the upper side of the partition plate 304.

[0045] The beneficial effect of the above embodiment is that by setting the partition plate, the air inlet pipe and the air outlet pipe, the effective management of the gas in the area between the storage chamber (lantern structure) and the buoy is achieved. The air inlet pipe can pass the gas and evenly distribute it to the lower part of the area through the bronchus, while the air outlet pipe is responsible for extracting the upper gas, forming a circulation of gas around the periphery of the buoy, which is conducive to the collection and centralized harmless treatment of harmful gases during the spraying process. At the same time, by adjusting the flow rate and temperature of the gas introduced into the air inlet pipe, the paint drying process can be accelerated and the production efficiency can be improved. The overall design is ingenious, which not only ensures good ventilation of the spraying environment, but also achieves the dual goals of environmental protection and high efficiency.

[0046] In this embodiment, a baking plate 3041 is provided on the side of the partition plate 304 close to the buoy, and the baking plate 3041 generates heat when powered on. In this embodiment, the design of the baking plate significantly improves the spray drying speed, and provides an additional heat source for the spraying area by generating heat when powered on, accelerating the volatilization of the solvent in the paint, thereby shortening the overall spraying cycle, improving production efficiency, and ensuring the stability of the spraying quality.

[0047] This embodiment is a buoy automatic spraying method, using the above-mentioned buoy automatic spraying device, including the following steps: Preparation step: Place the buoy body on the carrier assembly. The two ends of the buoy are supported by the first support platform 10 and the second support platform 11 respectively. Figure 2 ; The carrier assembly carries the buoy to the spray paint / paint booth. The spray paint / paint booth can refer to Fig.10 The spray paint / paint room is a device that provides a special environment for painting operations. It can meet the requirements of painting operations on temperature, humidity, etc., and can limit and treat the paint mist and organic waste gas generated during the spray paint operation before discharging. The slip ring 32 is installed on both ends of the buoy body, and the flexible membrane 33 and the longitudinal skeleton 34 contained in the first cavity 302 are unfolded along the circumference of the slip ring 32. The flexible membrane 33 and the longitudinal skeleton 34 form a lantern structure to cover the spray section of the buoy body. The first-stage spraying steps: the first supporting platform 10 and the second supporting platform 11 drive the buoy to rotate along its own axis; the first buoy paint is introduced into the first paint tube 20, and is evenly sprayed onto the busbar of the buoy through multiple first nozzles 21, and the buoy surface is evenly sprayed during the rotation of the buoy; during the rotation of the buoy, the baking plate 3041 generates heat and bakes the buoy surface; the air inlet pipe 305 introduces gas, and the gas is filled into the lower side of the partition plate 304 in the lantern structure through multiple bronchial pipes 3051. After the gas flows along the circumference of the outer surface of the buoy to the upper side of the partition plate 304 in the lantern structure, the air outlet pipe 306 extracts the gas. The first buoy paint is generally ordinary paint, and existing products on the market can be selected according to needs; Second stage spraying steps: the buoy stops rotating, and the first paint tube 20 stops spraying; the second nozzle 31 is fed with the second buoy paint and moves evenly along the direction of the sliding groove, and the second buoy paint is evenly sprayed onto the busbar of the buoy; after the second nozzle 31 moves to the other end, the first support platform 10 and the second support platform 11 drive the buoy to rotate to a set angle, the baking plate 3041 bakes the just-sprayed part, and the second nozzle 31 moves in the opposite direction to spray, and the above process is repeated until all spraying is completed. After the overall spraying is completed, it can also be manually operated to re-spray the local area. In the above process, the working mode of the air inlet pipe 305 and the air outlet pipe 306 is the same as the first stage spraying step. The second buoy paint is a special paint, which is sprayed on the area below the water level of the buoy. It can enhance the anti-corrosion performance, especially inhibit the growth and reproduction of marine organisms on the buoy. Antifouling paint (such as antifouling paint containing organic tin, self-polishing antifouling paint, low surface energy antifouling paint, biological antifouling paint, etc.) and traditional antifouling paint containing heavy metal oxides (such as paint containing copper, lead, mercury, etc., but the environmental protection is poor and is now less used); Three-stage spraying step: For the areas that were not sprayed in the first-stage spraying step and the second-stage spraying step, additional painting is carried out, such as the supporting parts.

[0048] In the above working process, the coating spray thickness control mainly depends on the nozzle spray flow rate per unit time and the area swept by the nozzle on the buoy.

[0049] First, consider the nozzle discharge flow rate. This flow rate is determined by the pressure of the fluid paint in the pipeline and the cross-sectional size of the pipeline, and can be expressed as a function: Q=f(P,A) Where Q is the spray flow rate, P is the paint pressure, and A is the pipe cross section.

[0050] To change the spray flow, we can adjust the paint pressure in the pipe. Generally, increasing the paint pressure will increase the spray flow, while reducing the paint pressure will reduce the spray flow. Although the pipe cross-section size can also affect the flow, it is fixed in most cases unless we replace the pipe with a different cross-section for fine-tuning.

[0051] Next, consider the area swept by the nozzle on the buoy. This area is determined by the angular velocity of the buoy, the radius of the buoy, and the spray shape (spray shape) of the nozzle, and can be expressed as a function: F=g(ω,r,S2) Where F is the area swept by the nozzle, ω is the angular velocity of the float, r is the radius of the float, and S is the spray shape of the nozzle (this is usually a fixed geometry, but can be adjusted by changing nozzles).

[0052] To change the swept area, we can adjust the angular velocity of the float. Increasing the angular velocity will cause the nozzle to sweep a larger area per unit time, while decreasing the angular velocity will reduce the swept area. The radius of the float and the spray shape of the nozzle are usually fixed, but we can consider replacing a float with a different radius or a nozzle with a different shape to further adjust the swept area.

[0053] Considering these two factors together. In order to obtain the desired coating thickness, we need to ensure that the total amount of paint sprayed onto the float per unit time is appropriate. This can be achieved by adjusting the paint pressure and the angular velocity of the float.

[0054] The coating thickness per unit area sprayed onto the buoy per unit time is: T = Q / F Where T is the coating thickness, Q is the spray flow rate, and F is the area swept by the nozzle.

[0055] If the paint pressure is high (controlling the spray flow rate Q) and the angular velocity of the float is moderate (controlling the area swept by the nozzle F), the amount of paint sprayed will be large, but the area swept will also be moderate, so a thicker coating can be obtained. On the contrary, if the paint pressure is low and the angular velocity of the float is fast, the amount of paint sprayed will be small, but the area swept will be large, so a thinner coating can be obtained.

[0056] By precisely adjusting the paint pressure in the pipe and the angular velocity of the float, we can effectively control the thickness of the coating. This process requires some practice and experience, but once the initial data is mastered, a uniform and satisfactory coating thickness can be obtained, and the rotation speed of the float and the pressure of the paint can be automatically adjusted by an automated controller to adjust the spraying thickness.

[0057] For example, PLC is used as the lower controller of the spraying device to directly control the buoy speed and pipeline flow. Then PLC and mobile phone are connected using WLAN, and the operator can use the upper computer on the mobile phone to adjust / control relevant parameters; or an industrial computer is placed in the paint room to adjust / control relevant parameters.

[0058] In summary, the present invention effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.
