Description

Technical Field

[0001] The invention belongs to the technical field of ship cleaning mechanical arms, and in particular relates to a ship surface attached organism cleaning mechanical arm. Background Art

[0002] Ships sail for a long time in highly corrosive seawater and highly adhesive marine biological environments. Organisms such as barnacles and algae are easily attached to the surface of ships. Cleaning the surface of ships is essential to maintaining the optimal performance of ships, because these organisms will increase the resistance of the hull, resulting in increased fuel consumption and decreased navigation efficiency. Using a robotic arm to clean the surface of ships is a modern and efficient method. In the existing technology, most of the ship surface cleaning robotic arms use high-pressure water jets to clean the organisms attached to the surface of the ship without easily damaging the surface of the ship. However, high-pressure water jets are prone to wastewater splashing everywhere, causing the cleaned biological debris to affect the environment.

[0003] The existing Chinese patent document with publication number CN117182950B proposes a high degree of freedom robotic arm for cleaning the surface of a hull. A rotating wheel is rotatably installed on the bottom surface of a movable ring, a rotating groove is opened in the middle of the rotating wheel and a spherical part is rotatably installed, an arc-shaped rolling groove is opened on the surface of the spherical part, a rolling body is rotatably installed on the inner wall of the rotating groove and the rolling body is located at the bottom of the arc-shaped rolling groove. When the rotating wheel rotates, it drives the spherical part and the brush roller installed on the outside of the spherical part to rotate, so as to clean the surface of the hull. However, the above cleaning form is prone to two situations. One is that the high-adhesion marine organisms are not cleaned properly, and the second is that excessive cleaning is easy to damage the surface of the ship.

[0004] Therefore, the present invention proposes a mechanical arm for cleaning organisms attached to the surface of a ship, which solves the problem in the prior art that the biological organisms attached to the surface of a ship are easily damaged by inadequate cleaning or excessive cleaning when the biological organisms attached to the surface of the ship are automatically cleaned by rotating a cleaning brush roller. The mechanical arm is improved by combining a high-pressure water jet and a cleaning scraper. First, a water jet is used to closely connect the attached organisms to the ship, and then a cleaning scraper is used to thoroughly scrape them off. At the same time, a wastewater recovery component is designed to prevent wastewater from splashing everywhere and affecting the surrounding environment. Summary of the invention

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figures 1 to 16The present invention provides a technical solution: a mechanical arm for cleaning biological attachments on the surface of a ship, comprising a mechanical arm mounting base 1, magnetic adsorption mobile crawler assemblies 11 are arranged on both sides of the mechanical arm mounting base 1, a control mounting box 2 is fixedly installed above the mechanical arm mounting base 1, a cleaning mechanical arm 3 is fixedly installed on the front surface of the control mounting box 2, a water jetting pipe 4 and a water suction pipe 5 are arranged below the cleaning mechanical arm 3, a water suction ring pipe 6 is arranged outside the water jetting pipe 4 and the water suction pipe 5, a rotating mounting seat 31 is rotatably installed below the inside of the cleaning mechanical arm 3, a water suction ring pipe 32 is fixedly installed above the inside of the cleaning mechanical arm 3, and one side of the water suction ring pipe 32 A drainage pipe 321 is fixedly installed on the inner wall, a motor gear drive assembly 33 is fixedly installed on the inner upper surface of the cleaning robot arm 3, an outer gear ring 311 meshing with the gear of the motor gear drive assembly 33 is fixedly installed on the outer surface of the rotating mounting seat 31, four groups of water jet pipes 4 are symmetrically arranged, a water inlet pipe 42 is fixedly installed in the middle of the four groups of water jet pipes 4, the water inlet pipe 42 is fixedly installed in the middle of the rotating mounting seat 31, a rotation limit sleeve adapted to the water inlet pipe 42 is arranged above the inner surface of the water suction ring pipe 32, a jet flat pipe 41 is symmetrically fixedly installed on the other side of the water jet pipe 4, and a booster nozzle 411 is fixedly installed inside one end of the jet flat pipe 41;In this embodiment, the robot arm mounting base 1 is used to install the control mounting box 2, and the control mounting box 2 is used to install the cleaning robot arm 3 and the communication control equipment. The robot arm mounting base 1 is adsorbed on the surface of the ship by the magnetic adsorption mobile track assembly 11 and moves, so that the cleaning robot arm 3 can move freely to clean the organisms attached to the surface of the ship. The rotating mounting seat 31 rotates 360° because the outer ring gear 311 rotates under the drive of the motor and gear of the motor gear drive assembly 33. The rotating mounting seat 31 also plays the role of installing the water jetting pipe 4, the water inlet pipe 42, the water suction pipe 5 and the water suction ring pipe 52. The water inlet pipe 42 connects the water jetting pipe 4 into a whole and rotates with the rotation of the rotating mounting seat 31. The upper part of the water inlet pipe 42 is matched with the rotating limit sleeve so that the water inlet pipe 42 can rotate stably inside the water suction ring pipe 32. The water inlet pipe 42 needs to be connected by a rotating joint. It can be used only after being connected to conventional known equipment such as a water supply pipe and a booster pump. This article will not go into details. The main design point of the water jet pipe 4 is that the water jet pipe 4 is located below the water suction pipe 5. After being connected, water is supplied. As the rotating mounting seat 31 rotates, the jet flat pipe 41 begins to jet the organisms attached to the surface of the ship. The flat pipe design with the outlet of the jet flat pipe 41 facing downward is combined with the internal partition short plate of the booster nozzle 411, which can effectively increase the flow rate of the ejected water, so that it forms a downward angle with the surface of the ship. The high-pressure water flow is used to remove and break the biological foot threads attached to the surface of the ship, or to loosen them, so as to form a pretreatment effect for the subsequent scraping, thereby improving the cleaning efficiency. At the same time, the water flow ejected obliquely downward by the jet flat pipe 41 is limited by the water suction ring pipe 6 and the filter screen 63, so that the water suction ring pipe 6 can recycle the wastewater and avoid the splash of wastewater affecting the surrounding environment. ;

[0021] For example 2, please refer to Figures 1 to 16On the basis of the first embodiment, the present embodiment further proposes that an assembly groove 51 is provided on one side of the water suction pipe 5, four groups of water suction pipes 5 are symmetrically provided, a water suction ring pipe 2 52 is fixedly installed in the middle of the four groups of water suction pipes 5, the water suction ring pipe 2 52 is sleeved on the outside of the water inlet pipe 42, the water suction ring pipe 2 52 is fixedly installed inside the rotating mounting seat 31, the upper end outer surface of the water suction ring pipe 2 52 is rotatably connected to the inner surface of the water suction ring pipe 1 32, a sealing gasket 322 is provided at the connection between the water suction ring pipe 1 32 and the water suction ring pipe 2 52, a movable mounting clamp 53 is movably installed below the water suction pipe 5, an assembly pipe 64 is symmetrically fixedly installed above the inner side wall of the water suction ring pipe 6, and an installation fixing compatible with the movable mounting clamp 53 is fixedly installed on the lower surface of the assembly pipe 64 Block 65, the movable mounting clamp block 53 and the mounting fixed block 65 are fixedly connected by bolts, a sealing guide cover 641 is fixedly installed on the inner surface of the assembly pipe 64, a filter screen 63 is symmetrically fixedly installed below the inner side wall of the water suction ring pipe 6, a slag discharge port 62 is symmetrically opened on the outer side wall of the water suction ring pipe 6, and guide plates 631 are symmetrically fixedly installed at both ends of the filter screen 63 near the slag discharge port 62, a closed bottom plate 61 is fixedly installed at the bottom of the water suction ring pipe 6, and a twisting scraper group 611 is evenly distributed on the lower surface of the closed bottom plate 61, a suction pump 21 is arranged inside the control installation box 2, the input pipe end of the suction pump 21 is fixedly connected to one end of the drain pipe 321, and a recovery pipe is fixedly installed on the output pipe end of the suction pump 21; in this embodiment, the water suction ring pipe 2 52 mainly serves to install and integrate the water suction pipe 5 into a whole. The water suction ring pipe 2 52 is also fixedly installed inside the rotating mounting seat 31 and rotates with the rotating mounting seat 31. The water suction ring pipe 2 52 is a hollow ring pipe. The upper end of the water suction ring pipe 2 52 and the water suction ring pipe 1 32 form an integral ring pipe with an upper half fixed and a lower half rotating. The sealing gasket 322 serves to increase the sealing of the connection. The water suction ring pipe 6 is connected to the assembly groove 51 on one side of the water suction pipe 5 through the assembly pipe 64. The end surface of the assembly pipe 64 in contact with the water suction pipe 5 is designed with a magnetic suction ring that attracts each other. The inner side of the assembly pipe 64 in contact with the water suction pipe 5 is designed with a sealing ring that fits each other. When installing the assembly pipe 64, it is mainly done by pushing the movable mounting clamp 53 into the water suction pipe 5. Move to both sides of the installation fixing block 65, and then fix the movable installation clamping block 53 and the installation fixing block 65 by bolts, so that the assembly pipe 64 and the suction pipe 5 are installed on the outside of the suction pipe 5 as a whole. When the assembly pipe 64 and the suction pipe 5 are installed, the sealing guide cover 641 is a guide ring whose side can be deformed and extended. When water flows into the assembly pipe 64 and the suction pipe 5, the sealing guide cover 641 will be expanded under the impact of the water flow, and play a role in guiding the water flow, so that the water flow passes smoothly through the connection between the suction pipe 5 and the assembly pipe 64, and flows directly into the assembly groove 51 from the assembly pipe 64, avoiding the impact of the water flow on the connection. After the suction ring pipe 6 is fixed to the suction pipe 5 through the assembly pipe 64, it is on the outside of the suction pipe 5 and the water jet pipe 4.The water flow sprayed obliquely downward by the jet flat tube 41 is intercepted by the water suction ring tube 6 and the filter screen 63. The filter screen 63 filters the wastewater and intercepts the debris of the organisms attached to the surface of the ship washed by the wastewater. The suction pump 21 works through the drainage pipe 321, the water suction ring tube 1 32, the water suction ring tube 2 52, the water suction pipe 5, the assembly pipe 64 and the water suction ring tube 6 to form a complete wastewater suction and recovery pipeline system. Most of the wastewater is intercepted and filtered by the filter screen 63 and then recovered through the water suction ring tube 6 to avoid wastewater splashing and affecting the surrounding environment. In addition, the water suction ring tube 6 is used as a recovery pipeline. The closed bottom plate 61 and the twisted scraper group 611 at the bottom thereof can scrape off the organisms attached to the surface of the ship as the water suction ring tube 6 is driven by the water suction pipe 5 to rotate. Because at this time, the organisms attached to the surface of the ship have been preliminarily cleaned by the water jet of the jet flat tube 41, and are relatively easy to be scraped off by the twisted scraper group 611. It is worth noting that the twisted scraper group 611 mainly consists of three groups of twisted rubber scrapers with different deflection angles. The two ends of the scraper are evenly rounded. This design can cover a larger area and the surface contour of the ship during the cleaning process as the water suction ring 6 rotates, and can effectively remove attached organisms. The angle difference of each group of scrapers enables them to form a uniform pressure distribution when contacting the curved surface of the hull, avoiding damage to certain areas due to excessive pressure, while also ensuring that each area is fully cleaned while reducing damage to the hull surface. The round head design further reduces the risk of damage to the hull surface caused by the scraper edge, and can better fit the surface. At the same time, it is less likely to be worn during the attached organism cleaning process. Another point is that the filter screen 63 is specially designed to be concave, which can increase the resistance to the water flow of the jet flat tube 41, and at the same time intercept the attached biological debris removed by the jet. As the water suction ring 6 is driven to rotate, the intercepted debris will be thrown out along the groove of the filter screen 63 under the action of centrifugal force, and discharged through the slag outlet 62 through the guiding effect of the guide plate 631 to avoid accumulation and splashing.

[0022] For example 3, please refer to Figures 1 to 16, on the basis of the second embodiment, the present embodiment further proposes that a reinforcement bottom plate 7 is fixedly installed on the lower surface of the cleaning robot arm 3 through bolts. A collar adapted to the rotating mounting seat 31 is provided on the upper surface of the reinforcement bottom plate 7. Ball bearings are evenly distributed on the lower surface of the reinforcement bottom plate 7. A cleaning frame 71 is fixedly installed on the side surface of the reinforcement bottom plate 7. The cleaning frames 71 are distributed in a triangular pattern. A cleaning brush plate 72 is fixedly installed on the lower surface of the cleaning frame 71. A combined scraper 73 is fixedly installed at one end of the cleaning frame 71. The shape of the combined scraper 73 is adapted to the shape of the filter screen 63; in this embodiment, the reinforcement bottom plate 7 can be disassembled from below the cleaning robot arm 3 through bolt installation. The ball bearings at the bottom of the reinforcement bottom plate 7 facilitate its movement on the ship surface. The cleaning frames 71 distributed in a triangular pattern can evenly cover the area cleaned by the spiral scraping blade group 611. During the movement, the cleaning brush plate 72 is used to brush the area cleaned by the spiral scraping blade group 611 again to clean the remaining biological debris. Moreover, the combined scraper 73 is installed at one end of the cleaning frame 71. When the water suction ring pipe 6 rotates, the combined scraper 73 can scrape the biological debris stuck inside the filter screen 63 to avoid clogging of the filter screen 63.

[0023] Embodiment 4, please refer to Figures 1 to 16 , on the basis of the third embodiment, the present embodiment further proposes a method for using a cleaning robot arm for attaching organisms on the ship surface, including the following steps: Step 1, place the robot arm mounting base 1 on the ship surface to be cleaned, ensure the stable adsorption and free movement of the magnetic adsorption moving track assembly 11 on the ship surface. After installation, connect the communication control device for debugging and feedback; Step 2, start after debugging is completed. As the rotating mounting seat 31 rotates, the injection flat pipe 41 starts to hydrate the organisms attached to the ship surface, and use the injected high-pressure water flow to remove or loosen the byssus of the organisms attached to the ship surface; Step 3, the suction pump 21 works, and most of the waste water is intercepted and filtered by the filter screen 63 and then recycled through the water suction ring pipe 6 to avoid splashing of waste water. The spiral scraping blade group 611 scrapes the organisms attached to the ship surface. The filter screen 63 intercepts the debris of the attached organisms removed by injection. The intercepted debris will be thrown out along the groove of the filter screen 63 under the action of centrifugal force and discharged through the slag discharge port 62 under the guiding action of the guide plate 631; Step 4, during the movement, the cleaning frame 71 uses the cleaning brush plate 72 to brush the area cleaned by the spiral scraping blade group 611 again to clean the remaining biological debris. The waste water sucked by the suction pump 21 is recycled and discharged at a fixed point through the waste water recovery pipe connected behind it.
