Description

Technical Field

[0001] The present application belongs to the technical field of wastewater recovery, and more specifically, to a cleaning device and a cleaning robot. Background Art

[0002] In order to achieve green rust removal of ships, the current method mainly uses robots equipped with cleaning devices to clean the walls of ships to be cleaned. Generally, during cleaning, the cleaning device sprays high-pressure water to clean the walls to be cleaned; among them, the wastewater generated by the high-pressure water after cleaning is easy to remain on the walls to be cleaned, causing the walls to be cleaned to rust again over a long period of time, and the direct leakage of wastewater during the cleaning process will also cause environmental pollution.

[0003] In order to solve the above problems, some cleaning devices with both cleaning function and vacuum wastewater recovery function are now available on the market. Specifically, a sealing gasket is set on the cleaning device. During cleaning, the sealing gasket is pressed against the wall to be cleaned, so that the cleaning device and the wall to be cleaned form a vacuum recovery chamber, so that the wastewater generated after cleaning is concentrated in the recovery chamber, and the wastewater in the recovery chamber can be vacuum recovered by a vacuum pump; in this way, the wastewater generated after cleaning is prevented from causing the wall to be cleaned to rust again, and the wastewater is also prevented from directly leaking and causing environmental pollution.

[0004] In order to ensure that the sealing gasket can well block the high-pressure water and prevent the high-pressure water from breaking the sealing gasket and the wall surface to be cleaned and leaking to the outside during cleaning, the sealing gasket is generally set as a hard structure with good rigidity; however, the shape of the wall surface to be cleaned of the ship is relatively complex, and there are many large curvature surfaces, convex surfaces and obstacles, etc.; for example, when encountering a weld, the sealing gasket made of a hard structure cannot fit the wall surface to be cleaned well, so that there is a gap between the sealing gasket and the wall surface to be cleaned, thereby affecting the vacuum degree of the recovery chamber, and then affecting the recovery effect of the wastewater. Therefore, the wall adaptability of the current cleaning device is poor, and it is difficult to ensure the vacuum degree of the recovery chamber, and thus it is difficult to ensure the vacuum recovery rate of the cleaning device for wastewater.

[0035] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0036] Please also read Figures 1 to 3 The cleaning device provided in the embodiment of the present application is used to clean the wall surface to be cleaned of a ship, and of course, it can also be used to clean the wall surface to be cleaned on other structures such as oil tanks.

[0037] The cleaning device includes a frame 10, a spray assembly 20 and a sealing assembly 30. The frame 10 is provided with a recovery hole 101, and the recovery hole 101 is used to connect an external vacuum pump. The spray assembly 20 is arranged on the frame 10; it can be understood that the spray assembly 20 can be connected to an external high-pressure water pump. When the high-pressure water pump is working, high-pressure water can be sprayed toward the wall to be cleaned through the spray assembly 20 to clean the wall to be cleaned. The sealing assembly 30 includes a flexible sealing cover 31 and a brush 32, and the flexible sealing cover 31 and the brush 32 are both arranged on the frame 10; the brush 32 is arranged around the outer periphery of the spray assembly 20, and the flexible sealing cover 31 is arranged around the outer periphery of the brush 32. It can be understood that the brush 32 is arranged on the inner peripheral wall of the flexible sealing cover 31; one end of the flexible sealing cover 31 away from the frame 10 and one end of the brush 32 away from the frame 10 are both beyond the spray assembly 20, so as to fit the wall to be cleaned.

[0038] Optionally, the spray assembly 20 is disposed on one side of the frame 10 along the axial direction of the recovery hole 101 toward the wall surface to be cleaned, for example, Figure 1 and Figure 3 As shown, the recovery hole 101 passes through the frame 10 in the vertical direction, and the spray assembly 20 is arranged at the lower side of the frame 10 and is used to spray high-pressure water generally downward, wherein the axial and vertical directions of the recovery hole 101 are as shown in FIG. Figure 1 and Figure 3 The schematic direction z is shown; it can be understood that the brush 32 and the flexible sealing cover 31 extend downward beyond the spray assembly 20; wherein, the spray assembly 20 is set here to be arranged on the inner side of the frame 10, that is, the side of the frame 10 facing the wall to be cleaned is set as the inner side of the frame 10, then the flexible sealing cover 31 and the brush 32 are both arranged on the inner side of the frame 10.

[0039] The working principle of the cleaning device provided in this embodiment is as follows: the spray assembly 20 is connected to the high-pressure water pump, the recovery hole 101 is connected to the vacuum pump, and the end of the brush 32 away from the frame 10 and the end of the flexible sealing cover 31 away from the frame 10 are both attached to the wall to be cleaned. At this time, the spray assembly 20 is facing the wall to be cleaned, and the frame 10, the vacuum pump, the flexible sealing cover 31 and the wall to be cleaned are enclosed to form a closed space; the high-pressure water pump is turned on, so that high-pressure water is sprayed toward the wall to be cleaned through the spray assembly 20 to clean the wall to be cleaned. Since the frame 10, the vacuum pump, the flexible sealing cover 31 and the wall to be cleaned are enclosed to form a closed space, the high-pressure water will not leak through the flexible sealing cover 31 and the wall to be cleaned when cleaning the wall to be cleaned, and the waste water generated by the high-pressure water after cleaning stays in the closed space, and will not leak through the flexible sealing cover 31 and the wall to be cleaned; after completing the cleaning work, the vacuum pump is turned on, and the waste water staying in the closed space is recovered through the recovery hole 101. In this way, after the wall surface to be cleaned is cleaned, based on the vacuum recovery operation, no waste water will remain on the wall surface to be cleaned, preventing the wall surface to be cleaned from rusting again, and also solving the problem of environmental pollution caused by waste water leakage.

[0040] It should be noted that, in the embodiment of the present application, the flexible sealing cover 31 is set as a flexible structure. Compared with the setting of a hard structure, the flexible sealing cover 31 has better deformation ability and better wall adaptability. The flexible sealing cover 31 can be locally deformed along with the shape of the wall to be cleaned to adapt to the complex shape of the wall to be cleaned. For example, the flexible sealing cover 31 can adapt to large curvature surfaces, convex surfaces and obstacles on the wall to be cleaned. In this way, the flexible sealing cover 31 can better fit the wall to be cleaned to avoid the formation of gaps between the flexible sealing cover 31 and the wall to be cleaned. In this way, the sealing effect between the flexible sealing cover 31 and the wall to be cleaned is ensured, and the vacuum degree of the enclosed space is ensured, which helps to improve the recovery rate of wastewater and prevent wastewater leakage.

[0041] It should also be noted that, in the embodiment of the present application, a brush 32 is further provided on the frame 10, and the flexible sealing cover 31 is arranged around the outer periphery of the brush 32, that is, the brush 32 is arranged on the inner peripheral wall of the flexible sealing cover 31. On the one hand, in order to ensure the wall adaptability of the flexible sealing cover 31, the flexible sealing cover 31 is relatively soft and easily deformed under the impact of external force, and the brush 32 has good water-blocking performance, so the brush 32 is arranged on the inner peripheral wall of the sealing cover, so that the brush 32 can block the water flow when the spray component 20 sprays water, preventing the water flow sprayed from the spray component 20 from flowing to the flexible sealing cover 31 and flushing the flexible sealing cover 31 and the wall to be cleaned, thereby further ensuring the fitting effect of the flexible sealing cover 31 and the wall to be cleaned, so that the flexible sealing cover 31 There is a good sealing effect between the brush 32 and the wall to be cleaned, so as to obtain a closed space with a good vacuum degree, so that waste water can be prevented from leaking between the flexible sealing cover 31 and the wall to be cleaned, and at the same time, the closed space with a good vacuum degree ensures the recovery rate of waste water during vacuum recovery; on the other hand, the brush 32 not only has a good water-blocking performance, but also has a good deformation ability, and the end of the brush 32 away from the frame 10 is used to fit the wall to be cleaned, so that the brush 32 also has a good wall adaptability, and the brush 32 can It can undergo adaptive local deformation along with the wall to be cleaned so as to fit well to the wall to be cleaned, thereby well and fully blocking the water flow sprayed by the spray assembly 20, which helps to ensure the fitting effect between the flexible sealing cover 31 and the wall to be cleaned; the setting of the flexible sealing cover 31 and the brush 32 enables the sealing assembly 30 to have good wall adaptability and sealing effect, and can adapt to the complex shape of the wall to be cleaned, such as the large curvature surface, convex surface and obstacles on the wall to be cleaned, thereby ensuring the vacuum degree of the enclosed space.

[0042] Therefore, the cleaning device provided in this embodiment has good wall adaptability, that is, the sealing component 30 of the cleaning device can fit well to the wall surface to be cleaned with complex shapes such as large curvature, convex surface, weld, etc., so that the cleaning device and the wall surface to be cleaned are enclosed to form a closed space with good vacuum degree, which can prevent the water sprayed by the spray component 20 during cleaning from leaking to the outside, and help the waste water to be better recovered through the recovery hole 101 for vacuum recovery, thereby improving the recovery rate of the waste water.

[0043] It should be supplemented that the cleaning device provided in this embodiment fits the wall to be cleaned through the brush 32 and the flexible sealing cover 31, and the brush 32 and the flexible sealing cover 31 have good local deformation capabilities and can undergo adaptive local deformation according to the shape of the wall to be cleaned to adapt to the wall to be cleaned. This helps to reduce the resistance of the cleaning device to move on the wall to be cleaned and improve the obstacle-crossing ability of the cleaning device.

[0044] Optionally, in the present embodiment, the flexible sealing cover 31 is configured as a silicone bladder, which is a soft bladder structure made of silicone material. The silicone bladder has good local deformation ability so that it can better fit the complex-shaped wall to be cleaned. That is, the silicone bladder has good wall adaptability so as to ensure the vacuum degree of the enclosed space, ensure the recovery rate of wastewater, and prevent leakage of wastewater.

[0045] Optionally, in the present embodiment, the flexible sealing cover 31 and the brush 32 are both configured as annular structures. It can be understood that the brush 32 is arranged around the periphery of the spray assembly 20, and the flexible sealing cover 31 is arranged around the periphery of the brush 32. Of course, in other embodiments, the flexible sealing cover 31 and the brush 32 can both be configured as frame-shaped structures. It can be understood that the brush 32 is framed around the periphery of the spray assembly 20, and the flexible sealing cover 31 is framed around the periphery of the brush 32.

[0046] In one embodiment, see Figure 3 The brush 32 includes a brush body 321 and a plurality of brush filaments 322; the brush body 321 is arranged on the inner side of the frame 10 and is arranged around the outer periphery of the spray assembly 20; the plurality of brush filaments 322 are distributed on the side of the brush body 321 away from the frame 10; the flexible sealing cover 31 is arranged around the outer periphery of the brush body 321 and the plurality of brush filaments 322, that is, the brush body 321 and the plurality of brush filaments 322 are all arranged on the inner peripheral wall of the flexible sealing cover 31.

[0047] It should be noted that the multiple brush wires 322 can jointly block the water flow sprayed by the spray assembly 20 to prevent the water flow from breaking through the flexible sealing cover 31 and the wall surface to be cleaned. The multiple brush wires 322 are arranged on the inner peripheral wall of the flexible sealing cover 31 to ensure the blocking of the water flow, so that the flexible sealing cover 31 and the wall surface to be cleaned have a good fitting effect; at the same time, the brush wires 322 also have good local deformation ability, can adapt to the complex shape of the wall surface to be cleaned, so as to better block the water flow, and can also make the sealing assembly 30 and the wall surface to be cleaned have a smaller resistance. In this way, by adopting the above technical solution, the sealing assembly 30 has a good wall adaptability to ensure the vacuum degree of the enclosed space, ensure the recovery rate of wastewater, and prevent wastewater leakage. At the same time, there is still a small resistance between the sealing assembly 30 and the wall surface to be cleaned, ensuring the obstacle crossing ability of the cleaning device.

[0048] In one embodiment, see Figure 3The frame 10 and the brush 32 are spaced apart, and the end of the brush 32 away from the frame 10 exceeds the flexible sealing cover 31, and can move toward the frame 10 under the action of an external force; the cleaning device also includes an elastic mechanism 40, which is connected between the frame 10 and the brush 32 to elastically push the brush 32. Among them, the end of the brush 32 away from the frame 10 exceeds the flexible sealing cover 31, and the elastic mechanism 40 is connected between the frame 10 and the brush body 321 of the brush 32.

[0049] It should be noted that the frame 10 and the brush 32 are distributed at intervals along the axial direction of the recovery hole 101; when the end of the brush 32 away from the frame 10 is in contact with the wall to be cleaned, the end of the brush 32 away from the frame 10 abuts against the wall to be cleaned, so that the brush 32 squeezes the elastic mechanism 40 under the reaction force of the wall to be cleaned, and moves toward the frame 10 along the axial direction of the recovery hole 101, so that the end of the brush 32 away from the frame 10 and the end of the flexible sealing cover 31 away from the frame 10 are both in contact with the wall to be cleaned, at this time, the elastic mechanism 40 is in a force storage state; when the brush 32 releases the wall to be cleaned, the elastic mechanism 40 resets and pops open the brush 32, so that the brush 32 moves back to the frame 10 along the axial direction of the recovery hole 101 under the elastic push action of the elastic mechanism 40, and the end of the brush 32 away from the frame 10 along the axial direction of the recovery hole 101 exceeds the flexible sealing cover 31.

[0050] By adopting the above technical solution, firstly, the elastic mechanism 40 elastically pushes the brush 32, and the brush 32 exceeds the flexible sealing cover 31, which helps the brush 32 to better fit the wall surface to be cleaned and produce adaptive deformation, thereby better and more fully blocking the water flow, preventing the water flow from breaking the flexible sealing cover 31 and the wall surface to be cleaned, and ensuring the sealing effect between the flexible sealing cover 31 and the wall surface to be cleaned; secondly, the brush 32 and the frame 10 The brushes 32 are distributed at intervals, and an elastic mechanism 40 is connected between the brush 32 and the frame 10, so that the brush 32 can move toward the frame 10 when it abuts against the wall to be cleaned, that is, the brush 32 moves away from the wall to be cleaned at this time, so that the brush 32 can better fit the wall to be cleaned, and at the same time, the flexible sealing cover 31 can fit the wall to be cleaned when the brush 32 moves toward the frame 10. In this way, on the one hand, it helps to ensure the vacuum degree of the above-mentioned enclosed space, thereby helping to improve the recovery rate of waste water and prevent waste water leakage. On the other hand, the brush 32 can adaptively deform according to the shape of the wall to be cleaned and move toward the frame 10. On the basis of ensuring the water-blocking ability of the brush 32, the friction between the brush 32 and the wall to be cleaned is reduced, thereby reducing the resistance of the cleaning device when it moves, which helps to improve the obstacle-crossing ability of the cleaning device.

[0051] In one embodiment, see Figure 4The elastic mechanism 40 includes an elastic member 42 and a guide rod 41; the elastic member 42 is connected between the brush 32 and the frame 10 to elastically push the brush 32; the guide rod 41 is connected to the brush 32 and is movably arranged in the frame 10; a limiter 43 is provided on the guide rod 41, and the limiter 43 can form a limit with the frame 10 to limit the travel of the elastic member 42 elastically pushing the brush 32. Among them, the guide rod 41 is connected to the brush body 321 of the brush 32, and the elastic member 42 is connected between the brush body 321 of the brush 32 and the frame 10.

[0052] It should be noted that the limiter 43 is arranged on the guide rod 41 and is arranged on the side of the frame 10 facing away from the brush 32, and can abut against the side of the frame 10 facing away from the brush 32 to limit the travel of the brush 32 moving away from the frame 10. When the end of the brush 32 away from the frame 10 is in contact with the wall to be cleaned, the end of the brush 32 away from the frame 10 abuts against the wall to be cleaned, so that the brush 32 squeezes the elastic member 42 under the reaction force of the wall to be cleaned, and moves toward the frame 10 along the axial direction of the recovery hole 101; at this time, the guide rod 41 moves synchronously with the brush 32 along the axial direction of the recovery hole 101 to achieve the guiding effect on the brush 32, and the limiter 43 and the guide rod 41 move synchronously along the axial direction of the recovery hole 101 away from the frame 10, so that the limiter 43 is arranged at intervals on the side of the frame 10 facing away from the brush 32; at this time, the elastic member 42 is in a power storage state. When the brush 32 releases the wall to be cleaned, the elastic member 42 resets and pops open the brush 32, so that the brush 32 moves along the axial direction of the recovery hole 101 toward the frame 10 under the pushing action of the elastic member 42; at this time, the guide rod 41 moves synchronously with the brush 32 along the axial direction of the recovery hole 101, and actually guides the brush 32, and the limit member 43 moves synchronously with the guide rod 41 along the axial direction of the recovery hole 101, to achieve a guiding effect on the brush 32, and the limit member 43 moves synchronously with the guide rod 41 along the axial direction of the recovery hole 101 toward the frame 10, and abuts against the side of the frame 10 facing away from the brush 32. At this time, the mutual abutment between the limit member 43 and the frame 10 limits the travel of the brush 32 moving back to the frame 10, which helps the brush 32 just exceed the flexible sealing cover 31.

[0053] By adopting the above technical solution, the setting of the guide rod 41 achieves a guiding effect on the brush 32, so that the brush 32 can move toward or away from the frame 10 more stably, thereby improving the flexibility of the brush 32 when moving, and helping the brush 32 to move adaptively when encountering a wall surface to be cleaned with a complex shape, thereby ensuring the fit between the brush 32 and the wall surface to be cleaned, so as to better and more fully block the water flow to the flexible sealing cover 31, ensure the vacuum degree of the above-mentioned enclosed space, and also help to reduce the resistance between the brush 32 and the wall surface to be cleaned, thereby ensuring the obstacle-crossing ability of the cleaning device.

[0054] Optionally, in a specific embodiment, the elastic mechanism 40 also includes a first bearing seat 44 provided on the frame 10 and a linear bearing 45 inserted into the first bearing seat 44, and the linear bearing 45 is sleeved on the guide rod 41. In this way, when the guide rod 41 moves driven by the brush 32, it can move more stably under the action of the linear bearing 45, thereby preventing the guide rod 41 from shaking during movement; optionally, sealing rings are sleeved between the first bearing seat 44 and the guide rod 41, and between the linear bearing 45 and the guide rod 41, thereby ensuring the sealing performance of the frame 10, thereby helping to ensure the vacuum degree of the above-mentioned enclosed space.

[0055] In one embodiment, please refer to Figure 1 and Figure 2 , multiple elastic mechanisms 40 are provided, and multiple elastic mechanisms 40 are evenly distributed on the brush 32 along the circumferential direction. It can be understood that multiple elastic mechanisms 40 are distributed on the brush 32 along the circumference of the brush 32, and multiple elastic members 42 are distributed on the frame 10 along the circumference of the frame 10. Then, the provision of multiple elastic mechanisms 40 ensures the stability of the brush 32 when moving, prevents the brush 32 from shaking when moving, helps to ensure the fitting effect between the brush 32 and the wall surface to be cleaned, and helps to ensure the resistance between the brush 32 and the wall surface to be cleaned.

[0056] In one embodiment, please refer to Figures 1 to 3 , Figure 5 The frame 10 includes a base plate 11 and a rib plate 12. The rib plate 12 is arranged on the base plate 11 to divide one side of the base plate 11 into a cleaning area 103 and a sealing area 104 surrounding the cleaning area 103. It can be understood that the rib plate 12 is set as an annular or frame-shaped structure. The rib plate 12 is arranged on the inner side of the base plate 11 to divide the inner side of the base plate 11 into a cleaning area 103 and a sealing area 104. The sealing area 104 is annular or frame-shaped and is used to install the sealing assembly 30. The spray assembly 20 is arranged on the inner side of the base plate 11 and is located in the cleaning area 103. The recovery hole 101 passes through the base plate 11 and is opened in the sealing area 104. The brush 32 is arranged in the sealing area 104, and the brush 32 and the base plate 11 are spaced apart. In addition, the elastic mechanism 40 is connected between the base plate 11 and the brush 32 and is arranged in the sealing area 104. In this way, the brush 32 is surrounded by the outer periphery of the cleaning area 103. The flexible sealing cover 31 is connected to the inner side of the substrate 11 and is disposed in the sealing area 104. The rib plate 12 is penetrated by a recovery channel 102 connecting the cleaning area 103 and the sealing area 104. It can be understood that the recovery through hole penetrates the rib plate 12 along the thickness direction of the rib plate 12, so that the recovery channel 102 connects the cleaning area 103 and the sealing area 104, so that the recovery channel 102 is connected to the recovery hole 101 through the sealing area 104.

[0057] It should be noted that, during operation, one end of the flexible sealing cover 31 away from the substrate 11 and the other end of the brush 32 away from the substrate 11 are in contact with the wall to be cleaned, so that the wall to be cleaned, the substrate 11, the flexible sealing cover 31 and the vacuum pump are enclosed to form a closed space, and the spray assembly 20 is directed toward the wall to be cleaned, and the spray assembly 20 sprays water toward the wall to be cleaned to clean the wall to be cleaned; at this time, due to the obstruction of the brush 32, the water sprayed by the spray assembly 20 stays in the closed space. It can be understood that the water sprayed by the spray assembly 20 stays in the cleaning area 103 and does not flow to the flexible sealing cover 31; the vacuum pump is turned on, and the water remaining in the cleaning area 103 is recovered through the recovery channel 102, the sealing area 104 and the recovery hole 101 in turn, so that the vacuum recovery operation of the wastewater is realized.

[0058] Among them, the division of the cleaning area 103 and the sealing area 104, the flexible sealing cover 31 and the brush 32 are both arranged in the sealing area 104, and the brush 32 is arranged around the outer periphery of the cleaning area 103, which rationally realizes the structural design of the cleaning device, determines the area of ​​the wall surface to be cleaned by the cleaning device, and helps to make the cleaning area 103 have a larger area, so that a larger area of ​​the wall surface to be cleaned can be cleaned.

It can be understood that the plurality of recovery channels 102 are distributed on the brush 32 along the circumferential direction of the rib plate 12, so that the waste water in the cleaning area 103 can evenly enter the sealing area 104 through the recovery channel 102, so as to be recovered through the recovery hole 101, thus ensuring the recovery efficiency of the waste water.

[0061] In one embodiment, see Figure 2The spray assembly 20 includes a spray rack 21 disposed on the frame 10 and a nozzle 22 disposed on the spray rack 21, and the nozzle 22 is used to spray water. It can be understood that the spray rack 21 is disposed on the inner side of the base plate 11 of the frame 10, and the nozzle 22 is disposed on the spray rack 21 and sprays water away from the base plate 11, so that water can be sprayed toward the wall surface to be cleaned when cleaning the wall surface to be cleaned, so as to achieve the cleaning operation of the wall surface to be cleaned.

[0062] Optionally, the spraying is set to be multiple, and the high-pressure water on the external high-pressure water pump can be sprayed toward the wall surface to be cleaned through multiple nozzles 22 after passing through the spraying frame 21, thereby improving the cleaning efficiency of the wall surface to be cleaned.

[0063] In one embodiment, please refer to Figures 1 to 3 The cleaning device also includes a pipeline assembly 50, which includes a rotating body 51 and a connector, which is a first connector 52; the rotating body 51 is arranged on the frame 10, and the first connector 52 is arranged on the rotating body 51; the spray frame 21 is rotatably connected to the rotating body 51 through the first connector 52, and can rotate when the nozzle 22 sprays water.

[0064] It can be understood that the rotating body 51 includes a fixed part and a rotating part. The fixed part is arranged on the frame 10 and can be connected to an external high-pressure water pump. The rotating part is rotatably arranged in the fixed part, and the spray frame 21 is connected to the rotating part through the first connecting head 52. During operation, the high-pressure water pumped out by the high-pressure water pump is sprayed onto the wall surface to be cleaned through the fixed part, the rotating part, the first connecting head 52, the spray frame 21 and the nozzle 22 in sequence; and, while the nozzle 22 sprays water, the spray frame 21 rotates. At this time, the first connecting head 52, the rotating part, the spray frame 21 and the nozzle 22 all rotate around the axis of the rotating body 51 to realize the circular water spraying of the nozzle 22. In this way, the cleaning area of ​​the wall surface to be cleaned is guaranteed; wherein, the axis of the rotating body 51 is parallel to the axial direction of the recovery hole 101, as shown in FIG. Figure 1 and Figure 3 The direction z is indicated in FIG.

[0065] In a specific embodiment, the spray assembly 20 further includes a second connection head 23 , and the second connection head 23 is connected to the first connection head 52 .

[0066] It should be noted that, in this embodiment, the spray rack 21 can rotate by the torque generated by the reaction force when the high-pressure water is sprayed to the wall surface to be cleaned, or it can rotate by the external force of a pneumatic or hydraulic motor or an electric motor. For example, in this embodiment, the spray rack 21 is set in a long strip shape, the water spraying direction of the nozzle 22 forms an angle greater than 0° with the rotation center line of the spray rack 21, and the water spraying direction of the nozzle 22 is deflected toward the width direction of the spray rack 21, wherein the rotation center line of the spray rack 21 is the axis of the rotating body 51, so that when the nozzle 22 sprays water toward the wall surface to be cleaned, the reaction force generated by the water flow when spraying toward the wall surface to be cleaned causes the spray rack 21 to deflect toward the width direction of the spray rack 21, so that the spray rack 21, the nozzle 22, the first connector 52, the second connector 23 and the rotating part rotate around the axis of the rotating body 51, thereby realizing circular water spraying, and the entire cleaning device moves relative to the wall surface to be cleaned during operation, ensuring the cleaning area of ​​the wall surface to be cleaned by the cleaning device.

[0067] In a specific embodiment, the base plate 11 of the frame 10 is provided with a mounting hole 105, and the first connector 52 is rotatably mounted in the mounting hole 105, wherein the mounting hole 105 penetrates the base plate 11 along the axial direction of the rotating body 51 and is located in the cleaning area 103. The frame 10 also includes a fixing frame 14 and a clamping member 15, wherein the fixing frame 14 is arranged on the base plate 11, the clamping member 15 is arranged on the fixing frame 14, and the clamping member 15 clamps the fixed part of the rotating body 51 to fix the fixed part. The pipeline assembly 50 also includes a second bearing seat 53 and a rotating bearing 54, wherein the second bearing seat 53 is arranged on the base plate 11, and the rotating bearing 54 is arranged in the second bearing seat 53 and is sleeved on the first connector 52. During operation, the setting of the rotating bearing 54 ensures the rotation stability of the first connector 52, thereby ensuring the rotation stability of the second connector 23, the rotating part, the spray frame 21 and the nozzle 22. Among them, sealing rings are provided between the first connecting head 52 and the base plate 11 and between the first connecting head 52 and the second bearing seat 53, which ensure the sealing performance of the frame 10, thereby helping to ensure the vacuum degree of the above-mentioned enclosed space.

[0068] Based on the above concept, the embodiment of the present application further provides a cleaning robot, which includes a robot body and a cleaning device, and a frame 10 is arranged on the robot body. Among them, the cleaning device in this embodiment is the same as the cleaning device in the previous embodiment. For details, please refer to the relevant description of the cleaning device in the previous embodiment, which will not be repeated here.

[0069] By adopting the above technical solution, the cleaning device has good wall adaptability, that is, the sealing component 30 of the cleaning device can well fit the wall to be cleaned with complex shapes such as large curvature, convex surface, weld, etc., so that the cleaning device and the wall to be cleaned are enclosed to form a closed space with good vacuum degree, which can prevent the water flow sprayed by the spray component 20 from leaking to the outside during cleaning, and help the waste water to be better recovered by vacuum through the recovery hole 101, thereby improving the recovery rate of waste water. In addition, the brush 32 and the flexible sealing cover 31 both have good local deformation ability, and can both undergo adaptive local deformation according to the shape of the wall to be cleaned to adapt to the wall to be cleaned. In this way, it helps to reduce the resistance of the cleaning device moving on the wall to be cleaned and improve the obstacle crossing ability of the cleaning robot.
