[0027] Example 1

[0028] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present application provides an underwater robot cleaning device, which includes a driving assembly 1 and a cleaning assembly 13, and the cleaning assembly 13 is detachably connected to the driving assembly 1. Specifically, the driving assembly 1 includes a warehouse body 2, and a driving device 3 and a transmission assembly 4 arranged in the warehouse body 2; wherein the driving device 3 is electrically connected to an external control system, and the two ends of the driving device 3 are respectively connected to and drive a group of transmission assemblies 4 to rotate in opposite directions. The cleaning assembly 13 includes two turntables 14, which are arranged side by side and adjacent to each other, and each transmission assembly 4 passes through the warehouse body 2 and is detachably connected to a turntable 14, so as to drive the two turntables 14 to rotate in opposite directions respectively.

[0029] In this regard, the cleaning device is fixedly installed on the underwater cleaning robot, and the driving device 3 can simultaneously drive the two sets of transmission components 4 to rotate in opposite directions at the same speed, thereby driving the two turntables 14 to rotate in opposite directions, generating a pulling force toward the front, which helps the robot to walk along the bottom of the ship and improves the cleaning efficiency. At the same time, the brush plate can be detachably connected to the transmission component 4, so that the bristles 15 of different materials can be replaced according to the material of the actual surface to be cleaned and the attachment of the attachments, so as to prevent the brush plate from damaging the coating of the surface to be cleaned when working. Here, by improving the structure of the cleaning device of the existing underwater robot, the linkage drive of the driving device 3 can be realized, the stability of the robot's work can be improved, thereby improving the cleaning efficiency and reducing energy consumption.

[0030] In a specific embodiment, each transmission assembly 4 includes a worm 10, a worm wheel 11 and a rotating shaft 12. The two opposite ends of the driving device 3 are respectively connected to a worm 10, the worm 10 is meshed with the worm wheel 11, the rotating shaft 12 passes through the warehouse body 2, and the two ends of the rotating shaft 12 are respectively fixedly connected to the worm wheel 11 and a rotating disk 14. Here, the driving device 3 drives the two worms 10 to rotate respectively, and the two worms 10 are respectively meshed with the two worm wheels 11, so that the two worm wheels 11 respectively drive the two rotating disks 14 to rotate in opposite directions.

[0031] In this embodiment, the driving device 3 is a motor capable of outputting at both ends. With one motor, the precise transmission of two groups of worm gears 10 and worm wheels 11 can be driven simultaneously, improving the transmission efficiency and stability. The two groups of worm gears 10 and worm wheels 11 respectively drive two brush disks to rotate in opposite directions at the same time, thus ensuring the consistency of the actions of the two brush disks and the cleaning synchronization, effectively preventing the robot from turning during operation due to uneven speeds of the two brush disks, and ensuring the stability and controllability of the underwater robot during operation.

[0032] In a specific embodiment, a number of groups of bristles are arranged circumferentially on the side of the turntable 14 away from the housing 2. Each group of bristles includes a number of bristles 15 arranged radially. The bristles 15 are inclined from the root 17 to the head 18 in the direction of the outer diameter. In this embodiment, the angle between the bristles 15 and the turntable 14 is 70°. In other embodiments, the angle between the bristles 15 and the turntable 14 can also be 60°, 65°, 75°, 80°, etc.

[0033] Furthermore, the head 18 of the bristle 15 is flat and the length of the contact surface is greater than the width of the root 17. The contact surface of the head 18 of the bristle 15 in contact with the surface to be cleaned is strip-shaped. Compared with the circular cross-section of the root 17, the cleaning width of the strip-shaped contact surface is larger and the cleaning efficiency is higher.

[0034] In this embodiment, the turntable 14 is made of a buoyant material, such as marine board, and the outer surface of the marine board is coated with epoxy resin to protect the marine board, thereby extending the service life of the turntable 14. During the cleaning process of the robot, the buoyant material can provide a certain buoyancy support for the robot, enabling it to maintain a stable posture when operating close to the surface to be cleaned, and further improving the operation stability of the underwater robot.

[0035] Please refer to Figure 3 , in a specific embodiment, a support core 19 and a plastic layer 20 are arranged along the length direction of the root 17 of the bristle 15, and the plastic layer 20 wraps the support core 19. In this embodiment, the support core 19 is made of stainless steel 304 steel wire rope, and the material of the head 18 is lead. When facing the heavy dirt cleaning task of the large underwater dock wall surface, the dirt may include rust, stubborn marine organism attachments, etc. At this time, when using this bristle 15, the stainless steel support core 19 and the lead head 18 can provide stronger scraping and brushing force, effectively removing stubborn dirt, while the plastic layer 20 plays a buffering and protecting role when the bristle 15 contacts the dock wall surface, preventing scratching the paint surface; at the same time, increasing the rotation speed of the driving device 3 to make it output greater power to drive the brush disk for powerful cleaning.

[0036] In a specific embodiment, the bin body 2 includes an upper cover 5, a lower cover 6, and a plurality of sealing strips 7. Among them, the upper cover 5 is fixedly connected to the lower cover 6, and the plurality of sealing strips 7 are respectively arranged at the connection between the upper cover 5 and the lower cover 6. Through the sealing strips 7, the tightness of the bin body 2 can be improved to prevent water from entering. The driving device 3 and the transmission assembly 4 are arranged inside the bin body 2. Each component operates in coordination to achieve stable output and efficient transmission of power, and at the same time ensure the tightness and reliability of the driving device 3 and the transmission assembly 4 when working underwater. A mounting plate 21 is fixedly connected to the side of the upper cover 5 away from the turntable 14. The cleaning device is connected to the fuselage of the underwater robot through the mounting plate 21 to ensure the stable installation of the cleaning device.

[0037] In a specific embodiment, a heat dissipation groove 8 is recessed from the outside to the inside on the side of the lower cover 6 close to the turntable 14. The position of the heat dissipation groove 8 corresponds to that of the driving device 3, and the heat dissipation groove 8 is not connected to the inside of the bin body 2. In this embodiment, a plurality of heat dissipation grooves 8 are provided and arranged in an array. Seawater can exchange heat with the driving device 3 through the heat dissipation grooves 8, so as to realize the heat dissipation of the driving device 3 and prevent the driving device 3 from being damaged due to overheating. The lower cover 6 is also provided with a wiring port 9, and an external power supply can be connected through the wiring port 9.

[0038] Embodiment 2

[0039] Please refer to Figure 4 , the difference between Embodiment 2 and Embodiment 1 of the present application lies in the structure and material of the bristles. Specifically, a plurality of bristle bundles 16 are arranged around the circumference on the side of the turntable 14 away from the bin body 2. The plurality of bristle bundles 16 are adjacent to each other, and each bristle bundle 16 is perpendicular to the turntable 14. Each bristle bundle 16 includes a plurality of bristles. In this embodiment, the material of the bristles is nylon.

[0040] When performing the task of routine cleaning on the surface of a small underwater pipeline, since the dirt on the pipeline surface is relatively light, mainly some slight attachments and algae. At this time, nylon bristles are selected, which are relatively soft in texture, can effectively remove dirt, and can minimize the possible damage to the pipeline surface to the greatest extent; at the same time, control the driving device 3 to run at a lower speed, which can not only meet the cleaning requirements, save energy, but also slow down the wear of the equipment.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
