[0030] See also Figures 1 to 5As shown, according to an embodiment of the present application, a signboard cleaning robot is provided, including a water tank 1, a driving vehicle 2 is fixedly installed at the bottom end of the water tank 1, an electric telescopic rod 3 is installed at the top of the water tank 1, a support plate 4 is installed at the top of the electric telescopic rod 3, support columns 5 are fixedly installed at the four corners of the top of the water tank 1, a support rod 6 is slidably connected to the inner side of the support column 5, a turntable 7 is installed at the top of the support plate 4, a fixed column 8 is fixedly installed at the top of the turntable 7, a fixing frame 10 is installed on one side of the outer surface of the fixing column 8, and a groove 101 is provided on the fixing frame 10. The sign cleaning robot also includes a brush assembly 11, which is detachably and rotatably mounted in the groove 101. A delivery hose 12 for supplying water to the brush assembly 11 is mounted on the fixed frame 10, and the delivery hose 12 extends from the fixed frame 10 to the water tank 1. A water pump 13 is mounted on the delivery hose 12. Mounting holes 16 are provided on both sides of the outer surface of the fixed frame 10. The mounting holes 16 are located on the side walls of the groove 101 and are connected to the groove 101. The sign cleaning robot also includes a locking device, which includes a locking rod 17, a fixing block 18 and a spring 19. The locking rod 17 is inserted into the mounting hole 16 and extends into the groove 101. One end of the locking rod 17 located in the groove 101 is connected to the fixing block 18. The spring 19 is sleeved on the locking rod 17, and one end of the spring 19 abuts against the fixing block 18, and the other end of the spring 19 abuts against the inner wall surface of the groove 101. The locking rod 17 has a first position for locking the brush assembly 11 in the groove 101 and a second position for releasing the brush assembly 11. In actual use, the locking rod 17 is moved axially along the mounting hole 16 by external force to switch between the above-mentioned first position and second position.

[0031] In the process of cleaning the robot, the water tank 1 needs to be driven to move to a suitable position by the driving vehicle 2, and then the support plate 4 needs to be driven to move by the electric telescopic rod 3, and then the support plate 4 needs to drive the support rod 6 to move inside the support column 5, and the support plate 4 needs to be limited by the support rod 6 to prevent the support plate 4 from being deflected. When the electric telescopic rod 3 drives the support plate 4, the turntable 7 and the fixed column 8 to move to a suitable height, the clean water in the water tank 1 can be extracted by the water pump 13, and then the clean water is transported to the brush assembly 11 through the delivery hose 12. The brush assembly 11 rotates to clean the signboard. When the brush assembly 11 is worn and needs to be replaced, the locking rod 17 can be pulled so that the locking rod 17 moves to the second position along the mounting hole 16. At this time, the brush assembly 11 is released by the locking device, and the damaged brush assembly 11 can be replaced. After that, the locking rod 17 is released, and the locking rod 17 can be moved to the first position under the restoring force of the spring 19, so that the locking device locks the brush assembly 11.

[0032] It can be seen that the structure of the cleaning robot of this embodiment reduces the workload of the staff when replacing the brush assembly 11, and can improve the working efficiency of the cleaning robot to a certain extent. In addition, when it is necessary to clean the signboards placed in different directions, the fixed column 8 can be driven by the turntable 7 to rotate to a suitable position so that the cleaning robot can clean the signboard. It is worth mentioning that in this embodiment, the delivery hose 12 has a certain redundancy, that is, the delivery hose 12 is relatively long, so as to avoid the delivery hose 12 being too short when the cleaning robot rotates, so that the delivery hose 12 is separated from the water tank 1 under the action of external forces of other components, resulting in the cleaning robot being unable to operate normally.

[0033] Further, the brush assembly 11 includes a mounting block 112 and a brush portion 113 rotatably mounted on the mounting block 112. The sign cleaning robot also includes a motor 9, which is mounted on the fixing column 8, and a rotating shaft of the motor 9 is drivingly connected to the brush portion 113 to drive the brush portion 113 to rotate.

[0034] Specifically, the mounting block 112 is fixedly mounted in the groove 101, the brush portion 113 is rotatably connected to the mounting block 112, and the rotating shaft of the motor 9 passes through the mounting block 112 and is connected to the brush portion 113, so that the brush portion 113 can rotate under the drive of the motor 9, so as to improve the cleaning efficiency of the cleaning robot for the sign. Figure 2 As shown, in a specific embodiment, the motor 9 is disposed in the brush portion 113 to drive the brush portion 113 to rotate.

[0035] Furthermore, a protruding section 111 adapted to the groove 101 is provided on one side of the mounting block 112 close to the fixing frame 10 , and the protruding section 111 is detachably connected to the groove 101 .

[0036] Specifically, when external force is applied to the brush assembly 11 , the raised section 111 on the mounting block 112 can slide into the groove 101 , and then the brush assembly 11 is locked by the locking assembly to achieve rapid assembly of the brush assembly 11 and the fixing frame 10 .

[0037] Furthermore, a clamping groove 14 is provided on the inner wall surface of the groove 101, and a clamping protrusion 1111 adapted to the clamping groove 14 is provided on the outer peripheral surface of the raised section 111, and the clamping protrusion 1111 is slidably connected in the clamping groove 14. In this embodiment, the clamping protrusion 1111 and the clamping groove 14 cooperate with each other, so that the brush assembly 11 has a certain limit and foolproof effect when it is assembled on the fixing frame 10, so as to avoid the brush assembly 11 and the fixing frame 10 from being misaligned.

[0038] In order to improve the assembly stability of the mounting block 112 and the locking device and prevent the mounting block 112 from being separated from the groove 101 under the action of external force, in this embodiment, fixing grooves 15 are provided on both sides of the outer surface of the mounting block 112, and the locking rod 17 is inserted into the fixing groove 15 and is in the above-mentioned first position, and the locking rod 17 is separated from the fixing groove 15 and is in the above-mentioned second position.

[0039] In order to prevent the motor 9 from being damaged due to the influence of gravity for a long time when the cleaning robot is used for a long time, a support platform 81 is provided on the side of the fixed column 8 away from the fixed frame 10. The motor 9 is mounted on the support platform 81, and the output end of the motor 9 passes through the fixed column 8 and the fixed frame 10 to be connected to the brush part 113. The support platform 81 provides support for the motor 9 to increase the service life of the motor 9.

[0040] Furthermore, a stopper 171 is provided at one end of the locking rod 17 away from the groove 101, and the stopper 171 protrudes from the outer peripheral side of the locking rod 17. In this embodiment, the stopper 171 is used to prevent the locking rod 17 from falling from the mounting hole 16 due to the elastic force of the spring 19 when the locking rod 17 moves from the second position to the first position.

[0041] In addition, a rotating shaft 21 is fixedly mounted on the top end of the supporting plate 4 , a rotating disk 7 is provided on the bottom end of the fixing column 8 , and the fixing column 8 is rotatably connected to the rotating shaft 21 via the rotating disk 7 .

[0042] Furthermore, a socket 22 is provided at the top of the turntable 7 and the support plate 4 , and the turntable 7 is connected via a threaded rod 23 passing through the socket 22 on the support plate 4 and the turntable 7 , and a knob 24 is installed at the end of the threaded rod 23 .

[0043] In this embodiment, the insertion hole 22 and the threaded rod 23 are provided to lock the cleaning robot after the cleaning robot rotates to a specific position, thereby preventing the cleaning robot from rotating during the cleaning operation.

[0044] In addition, the jacks 22 include a plurality of jacks 22, which are arranged at intervals along the circumferential direction of the turntable 7, and the threaded rods 23 are selectively and detachably connected to each jack 22. Specifically, the plurality of jacks 22 are evenly spaced along the circumferential direction of the turntable 7, and the threaded rods 23 are locked with the plurality of jacks 22 so that the fixing column 8 has a multi-angle adjustment function, for example, the angle between the line connecting two adjacent jacks 22 and the circumferential center can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45° and 50°.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.
