Description

Technical Field

[0001] The utility model relates to the technical field of underwater cleaning robots, in particular to a floating cleaning brush disc, a floating cleaning brush disc assembly and an underwater robot. Background Art

[0002] ROVs (Remote Operated Vehicles) are underwater robots used for underwater observation, inspection, and construction. With the rapid development of underwater ROVs in recent years, the underwater cleaning industry has also rapidly grown. However, the cleaning brushes currently installed on commercially available cleaning robots are mostly parallel to the robot body. This can lead to poor contact between the brush and the target when the cleaning area is uneven. To address this issue, industry technicians have gradually developed cleaning brush assemblies with floating effects. These assemblies incorporate a guide shaft between the brush and a fixed bracket, and a compression spring mounted on the guide shaft. This spring creates a floating effect and improves the contact between the brush and uneven areas of the target. However, this solution has the following drawbacks: The structure is complex due to its large number of components. During underwater cleaning operations, underwater attachments that fall off due to the cleaning action can easily obstruct the complex spring structure. For example, damaged barnacle shells can become lodged in the spring structure, affecting its expansion and compression, thereby compromising overall functionality.

[0003] Therefore, how to design a device that can make the cleaning brush plate have a floating effect, while at the same time avoiding the risk of failure of the floating buffer device caused by attachments that fall off during the cleaning operation invading the spring structure, is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] The purpose of the present utility model is to address the defects and shortcomings in the existing technology and provide a floating cleaning brush plate, a floating cleaning brush plate assembly and an underwater robot, so that the cleaning brush plate has a floating effect. At the same time, the device can also avoid the risk of failure of the floating buffer device caused by attachments that fall off during cleaning operations invading the interior of the spring structure, thereby increasing the service life of the device.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model provides a floating cleaning brush disc, comprising a cleaning brush disc and an underwater motor, a transmission device with a floating buffering effect is arranged between the output shaft of the underwater motor and the cleaning brush disc, the transmission device comprising a first connecting plate, a second connecting plate and an elastic deformation member fixedly connected to the first connecting member and the second connecting member respectively, the first connecting plate being transmission-connected to the output shaft of the underwater motor, the second connecting plate being fixedly connected to the cleaning brush disc, the elastic deformation member having a deformation space inside, and the deformation direction of the elastic deformation member being perpendicular to the line connecting the first connecting plate and the second connecting plate.

[0007] Preferably, a closed deformation space is provided inside the structure after the elastic deformation member is connected to the first connecting plate and the second connecting plate.

[0008] Preferably, the elastic deformation member is an annular rubber member.

[0009] Preferably, the first connecting plate and the second connecting plate are both bilaterally symmetrical structures, and the symmetry axis of the first connecting plate coincides with the symmetry axis of the second connecting plate.

[0010] Preferably, the output shaft of the underwater motor is connected to the first connecting plate or the elastic deformation member through a coupling.

[0011] Preferably, a flange is provided on the side of the coupling close to the transmission device, and the coupling is fixedly connected to the first connecting plate or the elastic deformation part through the flange; a first mounting hole is provided on the side of the coupling close to the output shaft of the underwater motor, and the output shaft of the underwater motor is placed in the first mounting hole and fixedly connected to the coupling.

[0012] Preferably, the cleaning brush plate has brushes made of metal.

[0013] The utility model also provides a floating cleaning brush disc assembly, comprising the floating cleaning brush disc and a mounting assembly, wherein at least two floating cleaning brush discs are mounted on the mounting assembly.

Since the first connecting plate and the second connecting plate are components that are not easy to deform, when the cleaning brush disc is subjected to external force, the first connecting plate will move toward the direction of the second connecting plate and thereby squeeze the elastic deformable member, causing the elastic deformable member to deform in a direction perpendicular to the connection line of the first connecting plate and the second connecting plate, thereby reducing the deformation space and increasing the elastic potential energy of the elastic deformable member.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 2As shown, the utility model provides a floating cleaning brush disc, including a cleaning brush disc 5 and an underwater motor 1, a transmission device 8 with a floating buffering effect is arranged between the output shaft of the underwater motor 1 and the cleaning brush disc 5, the transmission device 8 includes a first connecting plate 11 that is not easily deformed, a second connecting plate 9 that is not easily deformed and an elastic deformable part 10 with a non-spring structure, the first connecting plate 11 is transmission-connected to the output shaft of the underwater motor 1, the second connecting plate 9 is arranged opposite to the first connecting plate 11, and the second connecting plate 9 is fixedly connected to the cleaning brush disc 5; the elastic deformable part 10 is fixedly connected to the first connecting plate 11 and the second connecting plate 9, respectively, and the elastic deformable part 10 has a deformation space inside, and the deformation direction of the elastic deformable part 10 is perpendicular to the connecting line of the first connecting plate 11 and the second connecting plate 9. During operation, the underwater motor 1 is started, and the transmission device 8 rotates under the drive of the underwater motor 1 to perform underwater cleaning operations. Under the action of a force perpendicular to the transmission device 8, the first connecting plate 11 moves in the direction of the second connecting plate 9. At this time, the elastic deformable member 10 is squeezed and deformed to increase the elastic potential energy of the elastic deformable member 10. Under the push of the elastic potential energy, the cleaning brush disc 5 is tightly fitted with the surface of the object to be cleaned, thereby solving the problem of uneven target cleaning area caused by the curvature of the surface of the object to be cleaned or attachments on the surface of the object to be cleaned, resulting in poor contact between the cleaning disc and the wall surface of the target cleaning area, thereby improving the cleaning effect and cleaning efficiency. In addition, the elastic deformable member 10 with a non-spring structure can also solve the problem of the spring floating device failing due to detached attachments getting stuck in the spring, thereby increasing the service life of the transmission device 8 and the floating cleaning brush disc.

[0028] The elastic deformable member 10 can be a sheet-like member. In this case, a transmission device 8 needs to have two elastic deformable members 10, wherein the left side of the first connecting plate 11 and the left side of the second connecting plate 9 are connected to one of the elastic deformable members 10, and the right side of the first connecting plate 11 and the right side of the second connecting plate 9 are connected to the other elastic deformable member 10. This type of transmission device 8 has a through hole that runs through the front and back, and the through hole is connected to the outside world. This can cause water in the water area, attachments that fall off during cleaning, and other debris to easily enter the interior of the transmission device 8, resulting in excessive water pressure due to the diving depth being too deep, making it difficult for the first connecting plate 11 to move toward the second connecting plate 9; or because it has not been cleaned for a long time, the attachments in the transmission device 8 are piled up too high, making it difficult for the first connecting plate 11 to move toward the second connecting plate 9, reducing the floating buffering effect and causing damage to the transmission device 8. To this end, in one embodiment, the elastically deformable member 10, connected to the first connecting plate 11 and the second connecting plate 9, defines a closed deformation space within the structure. This prevents water or other debris from entering the deformation space, preventing the first connecting plate 11 from moving toward the second connecting plate 9 and thus affecting the floating effect. It also prevents seawater from corroding the interior of the conveyor 8 or impurities such as loose attachments from damaging the conveyor 8, thereby increasing the service life of the floating cleaning disc. In one embodiment, the elastically deformable member 10 is an annular rubber member. The rubber member has a certain damping effect, maintaining the basic posture of the cleaning brush disc 5 when not in use, preventing the cleaning brush disc 5 from interfering with the fixed structure.

[0029] In one embodiment, the first connecting plate 11 and the second connecting plate 9 are rigid plates that are not easily deformed. The first connecting plate 11 and the second connecting plate 9 are both bilaterally symmetrical structures, and the symmetry axis of the first connecting plate 11 coincides with the symmetry axis of the second connecting plate 9, ensuring that the force applied to the first connecting plate 11 is transmitted to the second connecting plate 9 as much as possible, so that the cleaning brush plate 5 can fit tightly against the object to be cleaned.

[0030] The output shaft of the underwater motor 1 is connected to the first connecting plate 11 or the elastic deformable member 10 through the coupling 7. In order to improve the connection firmness between the underwater motor 1 and the transmission device 8, a flange is provided on the side of the coupling 7 close to the transmission device 8, and the coupling 7 is fixedly connected to the first connecting plate 11 or the elastic deformable member 10 through the flange; a first mounting hole is provided on the side of the coupling 7 close to the output shaft of the underwater motor 1, and the output shaft of the underwater motor 1 is placed in the first mounting hole and fixedly connected to the coupling 7. The power of the underwater motor 1 is transmitted to the cleaning brush disc 5 through the coupling 7. This structure can maintain a torque of more than 50NM, so that the brush can clean off the attachments on the surface of the cleaned object and improve the cleaning ability. In one embodiment, the cleaning brush disc 5 has a brush made of metal material to further improve the cleaning ability.

[0031] The utility model also provides a floating cleaning brush disc assembly, which comprises a floating cleaning brush disc and a mounting assembly. At least two floating cleaning brush discs are mounted on the mounting assembly to increase the area of ​​a single cleaning and improve the cleaning efficiency.

[0032] The mounting assembly includes a motor mounting plate 2, a bearing mounting plate 3, and a mounting bracket 4. Both the motor mounting plate 2 and the bearing mounting plate 3 are fixedly connected to the mounting bracket 4. The underwater motor 1 is mounted on the motor mounting plate 2. The bearing mounting plate 3 is provided with a bearing 6. A coupling 7 is rotatably connected to the bearing mounting plate 3 via the bearing 6. The bearing 6 is a deep groove ball bearing. This arrangement facilitates assembly and component replacement, improving maintenance efficiency.

[0033] The present invention also provides an underwater robot, including a floating cleaning brush disc assembly, a second mounting hole 12 being provided on the mounting frame 4, and the floating cleaning brush disc assembly being fixedly connected to the underwater robot via the second mounting hole 12. During underwater operation, the underwater robot exerts force on the cleaning brush disc 5, and the first connecting plate 11 of the transmission device 8 is squeezed and deformed toward the second connecting plate 9. Under the pressure of the first connecting plate 11 and the elastic deformation member 10, the cleaning brush disc 5 fits tightly with the hull. By adjusting the force exerted by each propeller of the underwater robot, the optimal contact angle between the entire cleaning brush disc 5 and the cleaning area can be adjusted in real time, so that the cleaning brush disc 5 is always in the optimal cleaning position, thereby improving the cleaning effect and cleaning efficiency.

[0034] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention, and any reference signs in the claims should not be regarded as limiting the claims involved.
