[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Figure 1 This is a schematic diagram of the overall structure of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model; Figure 2 This is a schematic diagram of the overall structure of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model; Figure 3 This is a schematic diagram of the baffle side of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model.

[0017] like Figures 1 to 3 As shown, this utility model provides an electric roller brush device for underwater cleaning of inland waterway vessels, which includes a power unit 1 and a roller 2. One side of the power unit 1 is an output end 11, which is used to output torque, and the other side is an installation end 12. A brush 5 is installed on the roller 2. The two ends of the roller 2 are respectively provided with a first installation shaft 21 and a second installation shaft 22. The first installation shaft 21 is connected to the output end 11 of the power unit 1. When the power unit 1 outputs torque, the roller 2 and the brush 5 on it can rotate and scrape and brush the surface of the vessel. It also includes a baffle 3 and a transmission box 4. The baffle 3 is provided with a first connecting part 31 and a second connecting part 32. The mounting end 12 and the second mounting shaft 22 are respectively connected to the first connecting part 31 and the second connecting part 32. A detachable fastener is provided at the connection between the first connecting part 31 and the mounting end 12. The transmission box 4 is respectively connected to the output end 11 and the first mounting shaft 21. The roller 2 is inserted into the transmission box 4 through the first mounting shaft 21. Thus, when the first connecting part 31 and the mounting end 12 are connected by fasteners, the power unit 1 can drive the roller 2 and brush 5 to perform normal brushing work. When the first connecting part 31 and the mounting end 12 are unlocked, the second connecting part 32 of the baffle 3 can be separated from the second mounting shaft 22, and the roller 2 can be removed from the transmission box 4. Then, the roller 2 and brush 5 can be cleaned or replaced. Afterward, the mounting end 12 can be fixedly connected to the baffle 3 by fasteners for continued use. Through the above process, the roller 2 and brush 5 in the device can be quickly and conveniently removed and installed, which can effectively improve the brushing efficiency of the boat. A certain number of rollers 2 and brushes 5 can also be prepared in advance. During the brushing process, only the roller brushes are replaced. After the boat is brushed, the roller brushes are cleaned in batches, which can further shorten the time required to clean the boat and improve efficiency.

[0018] like Figure 3 As shown, in one preferred embodiment, the mounting end 12 of the power unit 1 and the second mounting shaft 22 of the roller 2 are rotatably mounted on the first connecting part 31 and the second connecting part 32, and the shaft length of the mounting end 12 rotatably engaging with the first connecting part 31 is greater than the shaft length of the second mounting shaft 22 rotatably engaging with the second connecting part 32. Thus, when the fasteners at the first connecting part 31 are removed, the baffle 3 is moved axially to separate it from the power unit 1 and the roller 2. After the baffle 3 is separated from the roller 2, the first connecting part 31 is still rotatably connected to the mounting end 12. At this time, the baffle 3 can be rotated to avoid the roller 2, and then the roller 2 can be removed from the transmission box 4. When the cleaned or new roller 2 is reinstalled on the transmission box 4, the baffle 3 can be rotated to reconnect it with the roller 2. By setting the baffle 3 to be rotatably connected with the power unit 1 and the roller 2, the efficiency of replacing the roller 2 can be further improved. Furthermore, such as Figure 2 and Figure 3 As shown, a cable 13 is provided at the mounting end 12 of the power unit 1. The cable 13 is used to connect to an external power source and control system. In actual use, the external facilities connected to the cable 13 cooperate with the mounting end 12 to limit the range of axial movement of the first connecting part 31 of the baffle 3 at the mounting end 12. When the first connecting part 31 is close to the main body of the power unit 1, the first connecting part 31 can be connected to the mounting end 12 by fasteners. The second connecting part 32 of the baffle 3 is connected to the second mounting shaft 22 of the roller 2. When the fasteners of the first connecting part 31 and the mounting end 12 are removed, and the first connecting part 31 is close to the aforementioned external facilities, the second connecting part of the baffle 3 is disengaged from the second mounting shaft 22. Therefore, during the disassembly and assembly of the roller 2, the baffle 3 is always kept in rotational connection with the power unit 1. There is no need to worry about the baffle 3 detaching from the device when disassembling and assembling the roller 2, which can further improve the efficiency and convenience of use.

[0019] Among them, Figure 2 and Figure 3 In the embodiment shown, a threaded hole 121 is provided on the mounting end 12, and a threaded through hole 33 is provided at the first connecting part 31 of the baffle 3. By installing screws into the threaded through hole 33 and the threaded hole 121, the baffle 3 and the power unit 1 can be fixedly connected. In some other embodiments, the baffle 3 and the power unit 1 can also adopt other fastening methods, as long as they can ensure that the electric roller brush can stably perform the brushing work after fastening.

[0020] Furthermore, the roller 2 and brush 5 can be an integral structure, or the brush 5 can be installed on the roller 2 by means of implantation. Additionally, the roller 2 and brush 5 can be provided in various specifications. The difference between these specifications lies in the specific materials used. For example, some rollers 2 and brushes 5 are made of plastic materials with a certain degree of hardness, such as nylon, while others are made of metal materials such as steel wire (brush 5). Plastic materials have lower affinity for oil stains, aquatic plants, and other debris and pollutants. Nylon rollers 2 and brushes 5 can be used first for preliminary cleaning of the hull's outer surface, during which oil stains, aquatic plants, and other dirt are less likely to adhere to the rollers 2 and brushes 5. Subsequently, metal brushes 5 are used to clean shellfish and rust on the hull, as their higher hardness effectively scrapes away these more stubborn dirt deposits. Moreover, based on the roller brush structure provided in this embodiment, the replacement of rollers 2 and brushes 5 is more convenient and quick, thus facilitating practical use.

[0021] It should be noted that the roller brush device provided by this utility model is generally used in automatic ship cleaning robots. The automatic ship cleaning robot can climb onto the hull and move on the hull, and then clean the hull by means of the roller brush device installed on it. During the cleaning process, the rollers and brushes installed on the roller brush device on the robot can be replaced and cleaned by the staff. Furthermore, in one preferred embodiment, a connecting part 14 is provided on the power unit 1 for connecting with the aforementioned automatic cleaning robot or other mobile propulsion facilities. Using the power unit 1 as the installation reference makes it easier to connect the cable 13 of the power unit 1 to the external facilities, and it is not necessary to remove the power unit 1 from the external facilities when replacing the roller brush, which is more convenient for practical use.

[0022] In one preferred embodiment, the portion of the transmission housing 4 connected to the first mounting shaft 21 has a transmission slot, into which the first mounting shaft 21 can be inserted, and the outer contour of the first mounting shaft 21 matches the inner contour of the transmission slot. This structure allows the roller 2 to be connected to the transmission housing 4 via the first mounting shaft 21, and the roller 2 can be directly inserted and removed from the transmission housing 4 via the first mounting shaft 21, improving its assembly and disassembly efficiency.

[0023] Figure 4 This is a schematic diagram of the transmission box side of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model; Figure 5 This is a cross-sectional view of the connection between the roller, transmission box, and baffle of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model. Figure 6 This is an exploded view of the connection between the roller and the transmission box of the electric roller brush device for underwater cleaning of inland waterway vessels provided in this embodiment of the utility model.

[0024] like Figures 4 to 6 As shown, in one preferred embodiment, the transmission box 4 includes a housing 41 and gears disposed within the housing 41. The gears include an input gear 421, a transmission gear 422, and an output gear 423. The power unit 1 and the roller 2 are driven through the gear pair, which can improve the stability of the transmission and ensure the cleaning effect.

[0025] In one preferred embodiment, both the output end 11 and the first mounting shaft 21 extend into the housing 41 of the transmission box 4, and are respectively connected to the input gear 421 and the output gear 423 via keyways. This simplifies the overall structure of the roller brush device, eliminating the need for bearings within the transmission box 4 (or, in Figure 4 In the middle, only the transmission gear 422 is equipped with a sealed bearing, so the roller brush device can maintain a good transmission effect when operating underwater, and the transmission mechanism of the roller brush device can also ensure the use effect when there is slight rust or some oil stains.

[0026] like Figure 5 and Figure 6 As shown, in one preferred embodiment, the roller 2 and the first mounting shaft 21 are separate structures. One end of the first mounting shaft 21 is fixedly connected to the output gear 423 of the transmission box 4, and the other end of the first mounting shaft 21 has a positioning part 214. A mating part 215 that cooperates with the positioning part 214 is provided at the end of the roller 2 that is close to the first mounting shaft 21. When the first mounting shaft 21 is positioned and engaged with the mating part 215 through the positioning part 214, the first mounting shaft 21 and the roller 2 can be locked together in the circumferential direction. Furthermore, in Figure 6In the illustrated embodiment, one end of the first mounting shaft 21 extends into the housing 41 via the power unit 211 and is fixedly connected (or keyway connected) to the output gear 423. A square shaft 212 is provided at the other end of the first mounting shaft 21. A connector is provided between the first mounting shaft 21 and the roller 2. One end of the connector is a square hole 213 that mates with the square shaft 212, and the other end is a positioning part 214. A transition hole 23 for mounting the connector is also provided on the roller 2. Thus, the roller 2... On the side facing the transmission box 4, the roller 2 is only connected to the transmission box 4 in a transmission manner (that is, it is only locked to each other in the circumferential and radial directions). On the other side of the roller 2, a baffle 3 is set to clamp the roller 2 between the baffle 3 and the transmission box 4. When removing the roller 2 from the transmission box 4, it is only necessary to remove the square hole 213 of the adapter from the square shaft 212 of the first mounting shaft 21. This can greatly improve the efficiency of disassembling and assembling the roller 2 and the transmission box 4, thereby improving the efficiency of replacing the roller 2 and the brush 5 in the roller brush device.

[0027] exist Figure 5 In the illustrated embodiment, the roller 2 and the second mounting shaft 22 are also separate structures. One end of the second mounting shaft 22 is fixedly mounted on the baffle 3, and the other end of the second mounting shaft 22 is mounted on the roller. The second mounting shaft 22 is rotatably connected to the roller 2 and / or the baffle 3. Preferably, the second mounting shaft 22 and the baffle 3 are rotatably connected, and the second mounting shaft 22 and the baffle 3 are locked together axially. In this way, the second mounting shaft 22 and the roller 2 only need to be connected by a simple plug-and-play connection, and the connection precision does not need to be too high. This also ensures the smoothness of the roller 2 when rotating relative to the baffle 3, thus improving the efficiency of assembling and disassembling the roller 2 on the baffle 3.

[0028] In summary, the electric roller brush device for underwater cleaning of inland waterway vessels provided by this utility model embodiment can greatly improve the replacement efficiency of the rollers and brushes in the roller brush device. When cleaning large vessels or vessels with a lot of attached dirt, the overall cleaning efficiency can be effectively improved by replacing the rollers and brushes in the roller brush device, reducing the time that the vessel needs to be moored for cleaning, and making it more convenient for actual production use.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
