Description

Technical Field

[0001] This invention relates to the field of ship maintenance auxiliary tools, specifically a robotic auxiliary tool for the maintenance of marine vessels. Background Technology

[0002] During the voyage of a ship at sea, once a ship is built and launched, it will generally spend its entire life in the water until it is decommissioned. This means that whether the ship is sailing or docked, its bottom is basically submerged in water. As a result, the bottom of the ship becomes a breeding ground for many marine organisms, including algae and shellfish, which attach to its surface and grow.

[0003] Under normal circumstances, attached shellfish and algae will not cause too much damage to the ship. However, long-term attachment will cause corrosion of the metal hull of the ship. At this time, the surface of the ship needs to be maintained. The maintenance usually involves cleaning the attached substances on the surface and then applying anti-rust paint to the exposed parts.

[0004] Currently, underwater robots are often used to perform this task. By installing negative pressure or magnetic suction mechanisms on the robot, it can attach to the surface of the ship and then perform cleaning by a motor-driven rotating cleaning component.

[0005] However, in actual operation, the rotating cleaning component is generally composed of a combination of metal bristles and plastic bristles. During the cleaning process, when there are large shellfish parasites, it is difficult to remove them, which takes more time and is very easy to damage the cleaning component and reduce its service life. On the other hand, there is also a risk that particularly large shellfish may get stuck in the cleaning component, causing the motor to burn out.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This application provides a robotic auxiliary tool for the maintenance of marine vessels, which solves the problem that in actual operation, the rotating cleaning component is generally composed of a combination of metal and plastic bristles. During the cleaning process, when there are large shellfish, it is difficult to remove them, which takes more time and is very easy to damage the cleaning component, reducing its service life. On the other hand, there is also a risk that particularly large shellfish may jam the cleaning component, causing the motor to burn out.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] This invention discloses a robotic auxiliary tool for the maintenance of marine vessels.

[0041] According to the appendix Figures 1-12As shown, the robot includes an auxiliary scraper 3 and a robot body 1. The auxiliary scraper 3 is installed at the front end of the robot body 1. A cleaning turntable 6 is installed at the bottom of the robot body 1, and a transmission mechanism 9 is installed at the top of the cleaning turntable 6. The top of the robot body 1 is connected to the circuitry on the ship's hull via a long wire or wireless communication for power supply and signal transmission control. The circuitry on the ship's hull refers to the circuit network composed of various electrical systems and equipment on the ship. The circuitry on the ship's hull includes, but is not limited to, the ship's power system, lighting system, communication system, navigation system, and automated control system. In the robot-assisted tools for marine ship maintenance, the robot needs to be connected to the circuitry on the ship's hull in order to obtain power, transmit signals, and perform remote control.

[0042] A support frame 2 is installed at the front end of the robot body 1. An auxiliary scraper 3 is movably inserted into the front end of the support frame 2. A rotating lever 5 is installed at the bottom of the support frame 2. Sliding push plates 4 are provided on both sides of the rotating lever 5.

[0043] The transmission mechanism 9 includes a rotating link 92 mounted on the top of the cleaning turntable 6. A drive shaft 93 is hinged to the front end of the rotating link 92. The drive shaft 93 is fixedly connected to the auxiliary scraper 3. A sliding rack 96 is slidably connected inside the support frame 2. A transmission bar 23 is hinged to both sides of the sliding rack 96. The sliding rack 96 is fixedly connected to the auxiliary scraper 3. The sliding rack 96 is used to push the rotating lever 5 to rotate. The transmission bar 23 pushes the two sets of sliding pusher plates 4 to move.

[0044] The advantages of the above technical solution are:

[0045] The robotic-assisted tool combines components such as an auxiliary scraper 3, a cleaning turntable 6, and a sliding pusher 4 to perform comprehensive cleaning of the ship's surface. The auxiliary scraper 3 removes impurities adhering to the hull surface, the cleaning turntable 6 provides cleaning power, and the sliding pusher 4 helps push the impurities to both sides of the ship, thereby achieving a thorough cleaning effect.

[0046] Through the design of the support frame 2, the rotating lever 5 and the sliding rack 96, the robot-assisted tool can move and rotate flexibly on the hull surface, adapting to hull surfaces of different shapes and curvatures, thereby covering a wider cleaning area and improving cleaning efficiency.

[0047] The transmission mechanism 9 enables the cleaning turntable 6 to rotate stably, while the fixed connection between the drive shaft 93 and the auxiliary scraper 3 ensures the stability and reliability of the cleaning effect. Simultaneously, the design of the sliding rack 96 and the transmission bar 23 allows the rotating lever 5 to maintain stable movement during the cleaning process, ensuring consistent cleaning results.

[0048] The top of the robot body 1 is connected to the ship's electrical circuitry via a long wire for power supply and signal transmission control. Operators can remotely control the robot's auxiliary tools, enabling remote monitoring and operation of ship maintenance work, thus improving operational convenience and safety.

[0049] Triangular tracked wheels 8 are mounted on the sides of the robot body 1. Permanent magnets are embedded in the tracks of the triangular tracked wheels 8. Magnetic strips 7 are installed on the bottom sides of the robot body 1. A drive motor 10 is installed inside the robot body 1, and a transmission belt connects the drive motor 10 to the cleaning turntable 6. The triangular tracked wheels 8 are driven by independent motors. Compared to rollers, the triangular tracked wheels 8 increase the contact area with the hull surface, increasing adsorption capacity. Furthermore, compared to front and rear tracked wheels, they facilitate turning. The permanent magnets embedded in the tracks enhance the magnetic attraction between the robot body and the hull, ensuring stable attachment of the robot to the hull surface for maintenance work even in complex marine environments. The magnetic strips 7 on the bottom sides of the robot body 1 further enhance the robot's adsorption force on the hull surface, ensuring stability during cleaning or inspection tasks. The drive motor 10 is connected to the cleaning turntable 6 via a transmission belt. This design effectively transmits the power of the drive motor 10 to the cleaning turntable 6, achieving efficient cleaning operations. Since each triangular track wheel 8 is driven by an independent motor, precise speed and direction control can be achieved for each wheel, improving the robot's operational accuracy. The independently driven tracks can better adapt to different shapes and inclinations of the hull surface, enhancing the robot's adaptability in complex environments.

[0050] An eccentric turntable 91 is mounted on the top of the cleaning turntable 6. The end of the rotating link 92 is rotatably connected to one side of the top of the eccentric turntable 91. Fixed arms 20 are integrally formed at both ends of the back of the support frame 2, and the fixed arms 20 are bolted to the outer surface of the robot body 1. The design of the eccentric turntable 91 allows the cleaning turntable 6 to generate eccentric motion when rotating. This motion increases the mechanical action during the cleaning process, thereby improving cleaning efficiency, especially when removing stubborn dirt or biological attachments from the hull surface. By changing the eccentric distance of the eccentric turntable 91, the cleaning force and range can be adjusted, allowing the robot to adapt to different cleaning needs. The design of the rotating link 92 ensures the stability of the cleaning turntable 6 during eccentric motion, preventing mechanical failures caused by excessive eccentric force. The fixed arms integrally formed at both ends of the back of the support frame 2 improve the strength and durability of the entire support structure, especially in harsh marine environments, where this design helps resist seawater corrosion and physical impact. The bolted connection also allows for adjustment of the position of the fixed arm 20 when necessary to adapt to different working environments or task requirements.

[0051] A sliding strip 94 is slidably inserted inside the support frame 2. A connecting rod 95 is fixedly connected to the end of the sliding strip 94. A sliding rack 96 is fixedly connected to the inner side of the connecting rod 95. A connector 22 is installed on the top of the rotating lever 5. The connector 22 includes an assembly tube 221 installed on the top of the rotating lever 5. A gear 223 is installed on the top of the assembly tube 221. The gear 223 meshes with the sliding rack 96.

[0052] A horizontal fixing bar 24 is fixedly welded to the top of the front end of the sliding rack 96. One end of the transmission bar 23 is hinged to the top of the horizontal fixing bar 24. A horizontal groove 25 is provided at the bottom of the support frame 2. A column 21 is fixedly welded to the top of the sliding pusher plate 4. The column 21 is slidably connected inside the horizontal groove 25. A sliding frame 26 is fixedly welded to the top of the column 21. The other end of the transmission bar 23 is movably hinged to the top of the sliding frame 26. The two sets of sliding bars 94 on the back of the auxiliary scraper 3 drive the connecting rod 95 to move, so that the sliding rack 96 moves back and forth inside the support frame 2. At this time, the sliding rack 96 drives the gear 223 to rotate continuously in both directions, so that the rotating lever 5 at the bottom of the gear 223 pushes the impurities to the outside of the sliding pusher plate 4. At the same time, during the back and forth sliding process of the sliding rack 96, the transmission bars 23 on both sides pull the sliding frame 26 to move back and forth laterally, so that the sliding pusher plates 4 on both sides push the impurities to the sides. Through the aforementioned mechanical motion chain, the robot can effectively clean the surface of the ship's hull. It can not only remove impurities but also push them to the sides, thereby keeping the cleaning area tidy. This improves the automation and efficiency of the cleaning process, making marine ship maintenance robot auxiliary tools more efficient and reliable when performing cleaning tasks.

[0053] A hexagonal connecting shaft 224 is welded to the bottom of gear 223. The bottom end of the hexagonal connecting shaft 224 is movably inserted into the interior of assembly tube 221. A connector 222 is integrally formed at the end of the rotating lever 5. The connector 222 is installed at the bottom of assembly tube 221. A memory spring 225 is provided between the hexagonal connecting shaft 224 and the connector 222. The memory spring 225 keeps the rotating lever 5 in close contact with the hull surface, preventing it from spinning freely. The memory spring 225 also allows the rotating lever 5 to adapt to slight unevenness on the hull surface, maintaining a stable working state.

[0054] A hexagonal locking post 227 is provided on the inner top of the connector 222. The hexagonal locking post 227 is movably inserted into the inner bottom of the assembly tube 221. A positioning shaft 229 is installed inside the hexagonal locking post 227. A locking spring 2210 is movably sleeved in the middle of the positioning shaft 229. Locking blocks 228 are movably sleeved on the outer surfaces of both ends of the positioning shaft 229. The bottom end of the locking block 228 passes through the connector 222. A slot 226 is opened on the outer surface of the bottom end of the assembly tube 221. The top end of the locking block 228 is movably inserted into the inside of the slot 226. The design of the hexagonal locking post 227 and the locking spring 2210 allows for quick loading and unloading of the rotating lever 5, facilitating maintenance and replacement, and improving the efficiency and convenience of using robot tools. The design of the positioning shaft 229 and the locking blocks 228 ensures a stable connection between the rotating lever 5 and the connector 222, preventing loosening during operation.

[0055] A positioning seat 18 is welded to the top of the support frame 2, through which the drive shaft 93 passes. A limiting groove 19 is formed inside the support frame 2, through which the sliding bar 94 passes. A connecting block 12 is fixedly welded to the front ends of the drive shaft 93 and the sliding bar 94. A connecting cover 11 is provided on the top of the auxiliary scraper 3, and the connecting block 12 is installed inside the connecting cover 11. The positioning seat 18 and the limiting groove 19 are designed to precisely position the drive shaft 93 and the sliding bar 94, ensuring their correct position and stable movement, thereby guaranteeing the accuracy and stability of the entire mechanism.

[0056] A fixing block 13 is welded to the top of the auxiliary scraper 3. A mounting groove 16 is provided on the back of the connecting cover 11, and the connecting block 12 is installed inside the mounting groove 16. Slots 17 are provided at the bottom of both the connecting cover 11 and the connecting block 12, and the fixing block 13 is movably inserted into the slot 17. The connecting block 12 is installed inside the connecting cover 11 and is combined with the fixing block 13 through the mounting groove 16 and the slot 17. This design provides a robust connection, ensuring the stability of the auxiliary scraper 3 during operation. This connection method also supports modular design, facilitating assembly and disassembly, and improving the efficiency of maintenance and replacement.

[0057] A connecting strip 15 is bolted to the front of the connecting cover 11. Positioning pins 14 are welded to the inner sides of both ends of the connecting strip 15, and these pins 14 are movably inserted into the interior of the fixing block 13. This design, where the connecting strip 15 is bolted to the front of the connecting cover 11 and the positioning pins 14 are inserted into the fixing block 13, enhances the strength and stability of the entire connection structure. This design also simplifies the assembly process, making connection faster and more convenient, and also allows for quick disassembly when needed.

[0058] The working principle of the device is as follows: When in use, the robot body 1 is slowly lowered along the outer wall of the ship and viewed underwater through the visual lens on the robot body 1. When the robot body 1 moves, it is attracted to the outer surface of the ship through the magnetic strip 7 at its bottom and the permanent magnet inside the triangular track wheel 8. Then it moves through the triangular track wheel 8. During the movement, the drive motor 10 is started, which drives the cleaning turntable 6 to rotate and clean.

[0059] Furthermore, during the aforementioned process, when the cleaning turntable 6 rotates, it causes the eccentric turntable 91 on top of it to rotate, which in turn causes the rotating connecting rod 92 to pull the drive shaft 93 back and forth. At this time, the front end of the drive shaft 93 pulls the auxiliary scraper 3 to move back and forth. Meanwhile, the auxiliary scraper 3 removes barnacles and shellfish attached to the surface of the hull from the front side of the robot body 1. At the same time, the two sets of sliding strips 94 on the back of the auxiliary scraper 3 drive the connecting rod 95 to move, which causes the sliding rack 96 to move back and forth inside the support frame 2. At this time, the sliding rack 96 drives the gear 223. The continuous forward and reverse rotation causes the rotating lever 5 at the bottom of gear 223 to push impurities to the outside of the sliding push plate 4. At the same time, during the forward and backward sliding of the sliding rack 96, the sliding frame 26 is pulled back and forth laterally by the transmission bars 23 on both sides, so that the sliding push plates 4 on both sides push the impurities to the sides. This achieves the cleaning of shellfish and avoids damage to the triangular track wheel 8 and cleaning turntable 6 caused by hard shells. Then, the cleaning turntable 6 at the rear cleans algae, moss and other soft-bodied plants and some rust spots on the surface of the hull.

[0060] After the device is used, the bolts on the outer surface of the connecting strip 15 are unscrewed, and then the two sets of positioning pins 14 are pulled out through the connecting strip 15. Then the auxiliary scraper 3 is pulled out downwards, and then the connecting cover 11 is removed from the outer surface of the connecting block 12, so that the auxiliary scraper 3 can be polished, repaired and replaced.

[0061] During use, the rotating lever 5 is pressed tightly against the hull surface by the memory spring 225 to ensure cleaning effect. At the same time, by pressing the two sets of locking blocks 228 towards the center, the locking spring 2210 is compressed, and the top of the locking block 228 is removed from the slot 226. At this time, the connector 222 can be pulled out from the bottom of the assembly tube 221 for easy cleaning and maintenance of the surface of the rotating lever 5.

[0062] In this embodiment, the visual lens provides underwater visual information to the operator, enabling remote monitoring of the robot's movement and cleaning operations on the vessel's exterior. The visual lens needs to operate under high pressure and low light conditions underwater; therefore, it can be equipped with a high-strength waterproof housing and underwater-compatible optical components. Images captured by the visual lens need to be transmitted back to the control console in real time, which can be achieved via wired (e.g., fiber optic cable) or wireless (e.g., underwater wireless communication technology). To ensure image clarity, the visual lens can be equipped with high-resolution sensors and image enhancement technologies such as optical image stabilization, autofocus, and night vision capabilities. Due to the harsh underwater environment, the design of the visual lens needs to consider the use of corrosion-resistant materials and ease of maintenance and replacement. Since the underwater environment can be very dark, the visual lens can be equipped with LED lights or other types of lighting equipment to provide sufficient light for clear video capture. In addition to video functionality, the visual lens system can also integrate other sensors, such as depth sensors and temperature sensors, to provide more information about the underwater environment.
