The extending direction of the top baffle 2 is perpendicular to the cleaning traveling direction of the cleaning device and is located on the side away from the surface to be cleaned. The motor mounting plate 5 is located on one side of the top baffle 2, and a driving motor 4 is arranged on the motor mounting plate 5. Drum mounting plates 9 are arranged on both sides of the top baffle 2, and drums 10 are rotatably arranged on the drum mounting plates 9. The drums 10 and the driving motor 4 are respectively located on both sides of the top baffle 2, and the drums 10 are used to act on the surface to be cleaned. A first synchronous pulley 6 is arranged at the end of the rotating shaft of the driving motor 4, and a second synchronous pulley 8 is arranged at one end of the drum 10. The first synchronous pulley 6 and the second synchronous pulley 8 are connected by a synchronous belt 7. The driving motor 4 drives the drum 10 to rotate through the first synchronous pulley 6, the synchronous belt 7, and the second synchronous pulley 8, so as to clean the surface to be cleaned. A connector 3 is installed through the top baffle 2, and water can be supplied to the drum 10 from the outside through the nozzle 3, and the drum 10 realizes rolling water washing of the surface to be washed.

[0029] The top baffle 2 is provided with side plates I 11 on both the front and rear sides in the traveling direction. The side plates I 11 and the roller 10 are on the same side of the top baffle 2. The two side plates I 11 are located on both sides of the roller 10 and are symmetrically arranged. The cross-section formed by the two side plates I 11 and the top baffle 2 is V-shaped. In other embodiments, the shape of the side plate 11 can also be changed so that the cross-sectional shape of the side plate 11 is changed to an arc or other shapes, which is not limited herein. The two side plates I 11 are structurally symmetric, and the structures on both sides of the roller 10 are symmetric. Taking one side as an example for description. The side plate I 11 is connected to the scraping assembly 13 through a spring hinge seat 12. In this embodiment, two spring hinge seats 12 are distributed in the length direction of the side plate I 11 at the connection position of the side plate I 11 and the scraping assembly 13. The spring hinge seat 12 includes a hinge and a torsion spring fixed on the hinge, so that the side plate 11 is hinged to the scraping assembly 13, and at the same time, the scraping assembly 13 has a tendency to rotate towards the roller 10 or the surface to be cleaned. Support seats I 16 are provided on both sides of the top baffle 2, and support seats II 17 are provided on the scraping assembly 13. The support seat I 16 is connected to the support seat II 17 through an electric push rod 15. The tail end of the electric push rod 15 is hinged to the support seat I 16, and the end of the output shaft is hinged to the support seat II 17. By the telescopic movement of the output shaft of the electric push rod 15, the scraping assembly 13 can be driven to rotate around the spring hinge seat 12. When the electric push rod 15 contracts, it drives the scraping assembly 13 to lift; when the electric push rod 15 extends, it drives the scraping assembly 13 to fall. The spring hinge seat 12 can play a role in pressing the scraping assembly 13 and can also play a buffering role when the electric push rod 15 pushes the scraping assembly 13.

[0030] The scraping assembly 13 is provided with a water suction port 18 and a water return port 14. The water suction port 18 and the water return port 14 are communicated inside the scraping assembly 13. The water suction port 18 is in contact with the surface of the object to be cleaned, and the water return port 14 is connected to a pumping and purification device, and the purified waste water can be recycled. To improve the recycling efficiency, two water return ports 14 are distributed in the length direction of the scraping assembly 13. In other embodiments, the number of the water return ports 14 can be increased or decreased according to specific situations, and is not limited to two.

[0031] The scraper assembly 13 includes a second side plate 131, a third side plate 132, a first scraper 133, and a second scraper 134. The second side plate 131 is connected to the first side plate 11 through a spring hinge seat 12. The third side plate 132 is arranged on the outer surface of the second side plate 131. An inverted trapezoidal protrusion 1311 is arranged on the outer surface of the second side plate 131 opposite to the third side plate 132, and a clamping groove 1326 matching the protrusion 1311 is arranged on the outer surface of the third side plate 132 opposite to the second side plate 131. The protrusion 1311 and the clamping groove 1326 are snap-connected to fix the second side plate 131 and the third side plate 132 together. A second support seat 17 is arranged on the outer surface of the third side plate 132, and the second support seat 17 is connected to the end of the output shaft of the electric push rod 15. The first scraper 133 is hinged to the edge of the second side plate 131 close to the surface to be cleaned, and the second scraper 134 is hinged to the edge of the third side plate 132 close to the surface to be cleaned. A water suction port 18 is formed by the gap between the first scraper 133 and the second scraper 134, and the water return port is arranged on the third side plate.

[0032] Water through grooves 1331 are distributed along the length direction on the edge of the first scraper 133 close to the surface to be cleaned. Raised blocks 1332 are arranged between the water through grooves 131, and the raised blocks 1332 face the second scraper 134. In this way, the waste water can flow into the water suction port 18 through the water through grooves 1331. At the same time, the raised blocks 1332 can prevent the first scraper 133 and the second scraper 134 from being pressed and deformed and then fitting together, avoiding the inability of the waste water to pass through. At the same time, the water suction speed of the waste water can also be increased through the water through grooves 1331. In this embodiment, a first connecting groove 1312 extending along the length direction is arranged on the edge of the second side plate 131. The cross-section of the first connecting groove 1312 is circular, and an opening is arranged on one side thereof. A first connecting protrusion 1333 matching the first connecting groove 1312 is arranged on the edge of the first scraper 133. The first connecting protrusion 1333 can rotate in the first connecting groove 1312, so that the first scraper 133 is hinged to the second side plate 131. A second connecting groove 1325 extending along the length direction is arranged on the edge of the third side plate 132. A second connecting protrusion 1341 is arranged on the edge of the second scraper 134. The connecting protrusion 1341 is rotationally nested in the second connecting groove 1325, so that the second scraper 134 is hinged to the third side plate 132.

[0033] On the inner surface of the third side plate 132, there are arranged a first flow guiding support plate 1321, a second flow guiding support plate 1322, a third flow guiding support plate 1323, and a fourth flow guiding support plate 1324. The first flow guiding support plate 1321 and the second flow guiding support plate 1322 form a group and are symmetrically arranged on both sides of the water return port 14 respectively. A channel 1327 for wastewater recovery is formed between the first flow guiding support plate 1321 and the second flow guiding support plate 1322, and the two gradually decrease in the direction away from the water suction port 18. The third flow guiding support plate 1323 and the fourth flow guiding support plate 1324 form a group and are symmetrically arranged on both sides of another water return port 14 respectively. And a another channel 1327 for wastewater recovery is formed between the third flow guiding support plate 1323 and the fourth flow guiding support plate 1324, and the two gradually decrease in the direction away from the water suction port 18. In other embodiments, the number of flow guiding support plates can be increased or decreased according to the number of water return ports 14, thereby increasing or decreasing the water return channels. The number and shape of the flow guiding support plates on both sides of each water return port 14 can also be changed, as long as it is ensured that the wastewater can be quickly drained to the water return port 14. The cross-sectional area of the water return port 14 gradually decreases in the water flow recovery direction, and the water return port is concave on the inner surface of the third side plate 132 and convex on the outer surface of the third side plate 132. The water suction port 18 is communicated with the water return port 14 through the channel 1327. The water return port 14 is connected to the suction and purification device. The wastewater generated after the roller 10 is cleaned is recovered and purified through the water suction port 18, the channel 1327, and the water return port 14 under the action of the suction device, avoiding secondary pollution caused by the wastewater remaining on the cleaned surface. The first flow guiding support plate 1321, the second flow guiding support plate 1322, the third flow guiding support plate 1323, and the fourth flow guiding support plate 1324 can not only guide the flow but also play a role in supporting and strengthening the third side plate 132. The distance between the flow guiding support plates gradually decreases in the direction away from the water suction port 18, having a better wastewater recovery efficiency.

[0034] This cleaning device is fixed on the cleaning robot. A suction and purification device or a wastewater recovery tank can be arranged on the cleaning robot. After the wastewater is suctioned to the wastewater recovery tank by the suction device, it is purified, or the wastewater is directly transported to the ground through a pipeline. In the initial state of this device, under the contraction action of the electric push rod 15, the scraper assembly 13 is lifted to avoid contacting the surface to be cleaned or other object surfaces, without affecting the movement of the cleaning device and the cleaning robot, as Figure 7 shown; when this device works, as Figure 8 shown, under the thrust action of the electric push rod 15, the scraper assembly 13 at the rear side of the advancing direction of this cleaning device is put down and pressed against the surface to be cleaned. The roller 10 cleans the surface to be cleaned at the front side, and the generated wastewater is recovered by the scraper assembly 13 at the rear side pressing against the surface to be cleaned, and the scraper assembly at the front side remains lifted; when the cleaning device changes direction, the scraper assembly 13 pressing against the surface to be cleaned is lifted, and the lifted scraper assembly 13 is put down and close to the surface to be cleaned to continue cleaning.

[0035] This device is mainly used for cleaning the surfaces of objects such as glass curtain walls and ship hulls. To improve the cleaning efficiency, it moves up and down reciprocally. In the initial state, the device can lift the scraper assembly 13. In the working state, the scraper assembly 13 on the front side of the roller is lifted, and the scraper assembly on the rear side is close to the surface to be cleaned, which can avoid interference between the scraper assembly 11 and the surface to be cleaned of the object during cleaning and generate resistance. In addition, the device also has the functions of waste water recovery and recycling, while avoiding secondary pollution of the surface to be cleaned by the waste water. The device has a simple structure, is easy to process, and has a lower cost.

[0036] The present invention also provides a cleaning robot, including the cleaning device of the above embodiment. Among them, the cleaning device can be arranged at the front end, rear end or both the front and rear ends of the body of the cleaning robot, and the cleaning device is driven by the robot to clean the surface of the object.
