[0002] As ships sail on the sea, the salt in the seawater has a greater corrosive effect, and rust often occurs on the surface of the ship. If the rusted hull is not removed, it will directly lead to erosion of the hull; of course, there are also some impurities and marine organisms (such as barnacles) attached to the surface of the hull, so a cleaning device is needed.

[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating the orientation and position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] One of the preferred embodiments of this application is as follows: Figures 1 to 11As shown, a cleaning device for a ship hull surface comprises a wall-climbing trolley 1, a frame 2, a grinding mechanism 3, an impact mechanism 4, and a drive mechanism 5. The frame 2 is mounted on the front end of the wall-climbing trolley 1, the grinding mechanism 3 and the impact mechanism 4 are both mounted on the frame 2, the drive mechanism 5 is mounted on the frame 2, and the output end thereof is in one-way transmission connection with the impact mechanism 4, and the output end of the drive mechanism 5 is connected to the grinding mechanism 3. It should be noted that the structural principle of the wall-climbing trolley 1 is common knowledge known to those skilled in the art and will not be described in detail.

[0033] It can be understood that this cleaning device has two modes, in which mode one: when the wall-climbing trolley 1 moves forward on the surface of the hull, the driving mechanism 5 performs the first action, and then the impact mechanism 4 and the grinding mechanism 3 will run simultaneously under the action of the driving mechanism 5, and the impact mechanism 4 will first contact the impurities, and then first wear the impurities to a set height; after the wall-climbing trolley 1 continues to move forward, the grinding mechanism 3 will grind and remove the impurities after being worn.

[0034] Mode 2: When the wall-climbing trolley 1 moves forward on the surface of the hull, the driving mechanism 5 performs the second action. At this time, the grinding mechanism 3 grinds and removes impurities under the drive of the driving mechanism 5, while the impact mechanism 4 remains stationary.

[0035] Thus, by utilizing two cleaning methods, when encountering thick impurities, the impact mechanism 4 and the grinding mechanism 3 can operate simultaneously to remove the impurities, significantly improving cleaning efficiency and saving working time. Furthermore, when the impurities are thinner, the grinding mechanism 3 alone can be used for cleaning, increasing the flexibility of the cleaning device. Furthermore, by providing a one-way transmission connection between the drive mechanism 5 and the impact mechanism 4, the device is not affected by the drive mechanism 5 when not in use, thus avoiding unnecessary energy consumption and wear, and extending the service life of the device.

[0036] As a further description of the above embodiment: Figure 3 、 Figure 6 and Figure 8 As shown, the grinding mechanism 3 includes multiple grinding rollers 301, which are vertically mounted on the bottom end of the frame 2 through the rotating shaft 11. The upper ends of adjacent rotating shafts 11 are connected through the transmission assembly 9, and the top end of one of the rotating shafts 11 is connected to the output end of the driving mechanism 5.

[0037] It should be known that no matter which mode is used, the grinding mechanism 3 is in operation. Therefore, when the driving mechanism 5 performs the first action or the second action, the driving mechanism 5 will drive one of the rotating shafts 11 to rotate, and then the remaining rotating shafts 11 will rotate synchronously under the drive of the transmission component 9, that is, the grinding roller 301 rotates to grind and clean impurities.

[0038] It should be noted that the structure and principle of the transmission assembly 9 are also well-known technologies known to those skilled in the art. In this embodiment, belt transmission is adopted, but gear transmission or chain transmission, etc. can also be adopted.

[0039] Of course, the surface of the hull is not a flat structure, but generally a curved structure. During grinding, the multiple grinding rollers 301 need to be close to or in contact with the surface of the hull to ensure a good cleaning effect. Therefore, the multiple grinding rollers 301 need to be elastically mounted in the vertical direction so that they can float up and down according to the curved surface structure of the hull during the grinding operation, ensuring that the grinding rollers 301 are always in close contact with or close to the hull surface, thereby improving the cleaning effect.

[0040] Specifically, such as Figure 9 As shown, the rotating shaft 11 includes an upper shaft 1101 and a lower shaft 1102. The upper shaft 1101 is rotatably mounted on the frame 2 and forms the upper end of the rotating shaft 11; a plurality of cylinders 12 are fixedly mounted on the bottom end of the frame 2, and the upper end of the lower shaft 1102 is movably arranged in the cylinder 12 through an elastic member 13 (i.e., a spring), and the upper shaft 1101 extends into the cylinder 12 and is connected to the lower shaft 1102 through a spline.

[0041] It can be understood that the grinding roller 301 is fixedly mounted on the outside of the lower shaft 1102; and when the upper shaft 1101 rotates, the lower shaft 1102 will also rotate under the action of the spline, thereby performing the grinding operation, and when the grinding roller 301 passes through the curved surface of the hull, the grinding roller 301 will move axially under the pressure of the hull, and at this time the lower shaft 1102 slides in the cylinder 12 and compresses the elastic part 13, and then the grinding roller 301 can be adjusted to float up and down according to the curved surface structure of the hull surface to ensure that the grinding roller 301 is always in close contact or close to the hull surface, thereby improving the cleaning effect and cleaning quality.

[0042] Of course, we know that since there are multiple grinding rollers 301, in order to prevent the operation of the multiple grinding rollers 301 from interfering with each other, a certain gap needs to be left between the multiple grinding rollers 301 during installation. In this way, the following shortcomings will inevitably occur during grinding: that is, during grinding, impurities corresponding to the gaps cannot be ground away, and subsequent grinding may be required, which will affect the cleaning efficiency.

[0043] Therefore, in order to solve the above technical problems, the installation method between the multiple grinding rollers 301 can be as follows: Figure 5 The installation is performed in the manner shown, that is, the projections of adjacent grinding rollers 301 toward the front end of the wall-climbing trolley 1 at least partially overlap.

[0044] Specifically, such as Figure 5As shown, we take the top two grinding rollers 301 as an example for explanation. The projection of the first grinding roller 301 toward the front end of the wall-climbing trolley 1 is ac, the projection of the second grinding roller 301 toward the front end of the wall-climbing trolley 1 is bd, and bc is the overlapping portion between the two grinding rollers 301. In this way, when the wall-climbing trolley 1 moves forward, although adjacent grinding rollers 301 are arranged at intervals, the overlapping arrangement of their projections ensures that during the grinding process, impurities corresponding to the gaps can be covered and polished away by the adjacent grinding rollers 301, thereby avoiding the need for subsequent re-grinding and improving cleaning efficiency and quality.

[0045] In one of the embodiments of the present application, Figure 6 and Figure 7 As shown, the impact mechanism 4 includes an impact hammer 401, a traction rod 402, and a rotating handle 403. The impact hammer 401 is horizontally slidably mounted on the front side of the frame 2, and the rotating handle 403 is mounted on the output end of the driving mechanism 5. The two ends of the traction rod 402 are respectively hinged or rotatably connected to the rotating handle 403 and the impact hammer 401. It can be understood that the impact hammer 401 forms a crank slider structure with the rotating handle 403 through the traction rod 402; that is, when the driving mechanism 5 drives the rotating handle 403 to rotate, the impact hammer 401 will slide back and forth under the action of the traction rod 402, thereby causing the impact hammer 401 to impact and damage the impurities, thereby reducing the thickness of the impurities and facilitating subsequent grinding operations.

[0046] Of course, to ensure the impact effect of the impact hammer 401, the material of the impact hammer 401 can be made of a high-hardness, wear-resistant material, such as alloy steel, to increase its service life and impact efficiency. At the same time, the shape of the impact hammer 401 can also be specially designed, such as a conical or wedge-shaped structure, to better penetrate impurities and produce an impact damage effect.

[0047] Further, such as Figure 4 As shown, the height of the impact hammer 401 relative to the hull surface is less than the height of the grinding roller 301. It can be understood that the impact hammer 401 is used to impact and destroy impurities, so the height of the impact hammer 401 relative to the hull surface is equivalent to the height of the impurities after being damaged by the impact, which we set as H. The height of the grinding roller 301 must be greater than H to thoroughly clean the impurities after the impact. If the height of the grinding roller 301 is less than H, it means that the thickness of the impurities is still thicker (higher) than the grinding roller 301, which will still make subsequent grinding more difficult and affect the cleaning efficiency. Therefore, to ensure the effectiveness and efficiency of subsequent cleaning, the height of the impurities after the impact must be less than the height of the grinding roller 301.

[0048] In one of the embodiments of the present application, Figure 6 、 Figure 10 and Figure 11 As shown, the driving mechanism 5 includes a motor 501, a transmission device 1 502 and a transmission device 2 503. The motor 501 is installed at the top of the frame 2. The input end of the transmission device 1 502 is connected to the output shaft of the motor 501 for one-way transmission, and the output end of the transmission device 1 502 is connected to the handle 403; the input end of the transmission device 2 503 is connected to the output shaft of the motor 501, and the output end of the transmission device 2 503 is connected to one of the rotating shafts 11.

[0049] It is understood that during the first operation (forward rotation of the motor 501), the motor 501 drives the handle 403 and the shaft 11 to rotate via the first transmission device 502 and the second transmission device 503, respectively, thereby simultaneously operating the grinding mechanism 3 and the impact mechanism 4 in mode 1. During the second operation (reverse rotation of the motor 501), the motor 501 drives the shaft 11 to rotate via the second transmission device 503, thereby simultaneously operating the grinding mechanism 3 in mode 2, while the first transmission device 502 is disengaged, thereby keeping the impact mechanism 4 stationary.

[0050] The present application does not specifically limit the structures of the transmission device 1 502 and the transmission device 2 503. A specific embodiment is provided below for reference. Specifically, Figure 7 、 Figure 10 and Figure 11 As shown, the transmission device 1 502 includes a gear 1 5021 and a gear 2 5022. The gear 1 5021 is mounted on the output shaft of the motor 501 through a one-way bearing 14. The gear 2 5022 is rotatably mounted on the frame 2 through a rotating rod 10. The handle 403 is mounted on the bottom end of the rotating rod 10. The gear 1 5021 and the gear 2 5022 are meshed. Figure 8 and Figure 10 As shown, the transmission device 2 503 includes a gear 3 5031 and a gear 4 5032. The gear 3 5031 is installed on the output shaft of the motor 501, and the gear 4 5032 is installed on one of the rotating shafts 11. The gear 3 5031 and the gear 4 5032 are meshed with each other.

[0051] It is understood that in mode 1, the motor 501 rotates forward, and the one-way bearing 14 is engaged. Therefore, the motor 501 drives the gear 2 5022 to rotate via the gear 1 5021. Simultaneously, the motor 501 drives the gear 4 5032 to rotate via the gear 3 5031, thereby causing the handle 403 and the shaft 11 to rotate synchronously. In mode 2, the motor 501 rotates reversely, and the one-way bearing 14 is free. Therefore, the motor 501 drives the gear 4 5032 to rotate via the gear 3 5031, thereby rotating the shaft 11, while the gear 1 5021 and the gear 2 5022 remain relatively stationary (i.e., the transmission device 1 502 is disengaged).

[0052] It can be seen that two cleaning modes can be achieved by the forward and reverse rotation of a motor 501, which can reduce the installation of the driving source. The wall-climbing trolley 1 itself is a compact device, so such a design can not only save costs, but also further reduce the volume and weight of the entire cleaning device, making the entire device easier to operate.

[0053] In this embodiment, Figure 1 As shown, in order to further improve the accuracy and effect of cleaning the device, a camera 7, a spraying device 6 and a safety ring 8 can be installed on the top of the wall-climbing trolley 1 and the frame 2.

[0054] It is understood that before polishing, the camera 7 is used to capture images of the hull surface in real time to determine the type of impurity. For example, in the case of rust impurities, the spraying device 6, in conjunction with the camera 7, can spray a rust remover onto the hull, thereby softening the rust impurities and facilitating subsequent polishing and impact operations. The safety ring 8 can be connected to the safety rope to prevent the wall-climbing vehicle 1 from falling.

[0055] Specifically, such as Figure 1 and Figure 2 As shown, the spraying device 6 includes a water tank 601, a micro water pump 602 and a pair of nozzles 603. The water tank 601 is fixedly installed on the top of the wall-climbing vehicle 1, and the nozzles 603 are fixedly installed on the top of the frame 2 and are located on both sides of the camera 7. The input end of the water pump is connected to the water tank 601, and the output end of the water pump is connected to the nozzle 603 through a water pipe.

[0056] It is understandable that an appropriate amount of rust remover is injected into the water tank 601, and then the rust remover is extracted from the water tank 601 by the micro water pump 602, and transported to the nozzle 603 through the water pipe, and finally the rust remover is evenly sprayed on the surface of the hull by the nozzle 603. Such a double nozzle 603 design allows the rust remover to act accurately on the rust impurities, thereby more effectively softening the rust body and improving the subsequent cleaning efficiency and cleaning quality. At the same time, the design of the nozzle 603 on both sides of the camera 7 also ensures that the camera 7 can capture the surface of the hull after spraying the rust remover in real time, so that the operator can better judge the cleaning effect and perform subsequent operations.

[0057] The working principle of the present invention is:

[0058] First, the staff connects the safety ring 8 via a safety rope, then places the wall-climbing trolley 1 on the hull surface and maneuvers it along the hull surface to a set position to clean the impurities. For example, for thick barnacle impurities, mode 1 is activated, i.e., motor 501 rotates forward. At this time, the one-way bearing 14 is engaged, and motor 501 drives gear 2 5022 via gear 1 5021. Simultaneously, motor 501 drives gear 4 5032 via gear 3 5031, thereby causing the handle 403 and the shaft 11 to rotate synchronously. The impact hammer 401 reciprocates to impact and thin the impurities, and the rotating grinding roller 301 then grinds the impacted impurities, thereby removing the impurities. When rust is encountered, mode 2 is activated. Of course, the rust is sprayed on the rust through the spraying device 6 before grinding to soften the rust; then the motor 501 reverses, and the one-way bearing 14 is in a free state, that is, the impact mechanism 4 remains stationary, and the motor 501 drives the gear 4 5032 to rotate through the gear 3 5031, that is, the rotating shaft 11 rotates, and then the grinding roller 301 grinds and removes the softened rust.

[0059] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and description merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements are intended to fall within the scope of the present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
