Description

Technical Field

[0001] The utility model relates to the technical field of LED screen cleaning, and in particular to an outdoor LED screen cleaning robot. Background Art

[0002] LED screen is a display device that uses LED (light-emitting diode) as a light source. It is usually composed of many small LED lights that can emit light of different colors to form images or text. LED screens are widely used in indoor and outdoor billboards, stage backgrounds, TV walls, information display screens and other occasions. They have the advantages of high brightness, low energy consumption, long life and rich colors.

[0003] With the development of science and technology, LED screens have been widely used in outdoor advertising, public information release and other fields. However, due to long-term exposure to the outdoor environment, dust and dirt are easily accumulated on the surface of the LED screen, affecting its display effect and service life. At present, cleaning outdoor LED screens mainly relies on manual operation. Since LED screens are usually located at high places, manual operation is required, which has a high safety risk, high labor intensity, time-consuming and labor-intensive, and slow manual cleaning speed. The cleaning efficiency is low and it is easy to damage the display screen. Therefore, there is an urgent need for an outdoor LED screen cleaning robot to solve the above technical problems. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides an outdoor LED screen cleaning robot, which is moved by means of steel cable lifting, can be adsorbed on the surface of the LED screen, and removes dust and dirt on the surface of the LED screen by means of a brush and cleaning fluid, thereby realizing automatic cleaning and improving cleaning efficiency and effect.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An outdoor LED screen cleaning robot comprises a fixed shell and a steel cable, wherein the left and right sides of the fixed shell are connected with the steel cable via fixed joints, a cleaning mechanism is arranged inside the fixed shell, a flushing mechanism is arranged on the front side of the fixed shell, and a driving mechanism is arranged on the outside of the fixed shell.

[0007] Furthermore, the driving mechanism includes a driving motor, a driving gear, a driven gear, a transmission shaft and a traveling rubber wheel. The transmission shaft is arranged through the interior of the fixed shell. Both left and right ends of the transmission shaft are equipped with rotatable traveling rubber wheels. A driving motor is fixedly provided on the left side of the front surface of the fixed shell. A driving gear is installed on the output end of the driving motor. A driven gear is installed on the left side of the transmission shaft ring surface, and the driven gear is meshed and transmitted with the driving gear.

[0008] Furthermore, a bearing is installed at the connection between the transmission shaft and the fixed housing.

[0009] Furthermore, a plurality of groups of suction cups are evenly arranged on the annular surface of the walking rubber wheel.

[0010] Furthermore, the flushing mechanism includes a diverter, an infusion tube, a diverter branch, a baffle and a nozzle. The diverter is installed on the front surface of the fixed shell. Baffles are provided on the upper and lower sides of the fixed shell. Multiple groups of nozzles are embedded in the baffle. The nozzles are connected to the diverter through the diverter branch. The infusion tube is connected to the input end of the diverter.

[0011] Furthermore, a scraper with an inclined structure is provided at the outer end of the baffle.

[0012] Furthermore, the cleaning mechanism includes a cleaning roller, a motor, a driving pulley, a transmission belt and a driven pulley. The cleaning roller is provided in two groups and is respectively arranged on the upper and lower sides inside the fixed shell. The right ends of the two groups of cleaning rollers are equipped with driven pulleys. The right side of the front surface of the fixed shell is equipped with a motor, and a driving pulley is installed on the output end of the motor. The driving pulley and the two groups of driven pulleys are connected by a transmission belt.

[0013] Furthermore, the cleaning roller is composed of a brush, a roller and a supporting shaft. The supporting shaft is assembled inside the fixed shell and rotatably connected thereto. The outer side of the supporting shaft is provided with a roller. The outer side of the roller is provided with a layer of brush, and the surface of the cleaning roller protrudes from the rear surface of the fixed shell.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model is moved by means of steel cable hoisting. The walking mechanism can be adsorbed on the surface of the LED screen. The flushing mechanism and cleaning mechanism can quickly clean the surface of the LED screen. The cleaning liquid sprayed by the brush and nozzle can remove dust and dirt on the surface of the LED screen, realizing automatic cleaning, which can not only improve the cleaning efficiency and reduce the labor intensity of manual labor, but also reduce the safety risks that may occur during the cleaning process.

[0016] 2. The utility model can drive the cleaning robot to move along the surface of the LED screen through the drive mechanism, which is convenient for cleaning different positions on the surface of the LED screen, and improves the convenience and efficiency of cleaning. The driving gear is directly connected to the output end of the driving motor to receive the power of the motor. The driven gear is assembled with the left annular surface of the transmission shaft and meshes with the driving gear, so that the power is transmitted from the driving gear to the transmission shaft, and through the transmission shaft, the power is transmitted from the driving motor to the walking rubber wheel, so that the robot is driven to move on the surface of the LED screen through the rotation of the walking rubber wheel.

[0017] 3. There are multiple groups of suction cups evenly arranged on the ring surface of the walking rubber wheel. The adsorption force of the suction cups enables the robot to move more stably on the surface of the LED screen. When the walking rubber wheel contacts the surface of the LED screen, the suction cups will be adsorbed on the surface of the LED screen, which can provide additional adhesion to help the robot move better on the screen. At the same time, due to the additional adhesion provided by the suction cups, the robot is not easy to slip or move, thereby reducing safety risks. Especially when cleaning at high places or edge positions, this design can significantly improve the safety of the robot.

[0018] 4. Through the flushing mechanism, the cleaning liquid can be sprayed onto the surface of the LED screen, which can clean the dust and dirt adhering to the surface of the LED screen, realize the rapid cleaning of the surface of the LED screen, and improve the cleaning efficiency and cleaning effect of the surface of the LED screen.

[0019] 5. A scraper with an inclined structure is provided at the outer end of the baffle, and the scraper can fit into the surface of the LED screen. When the robot moves, the scraper can remove water stains and dirt on the surface of the LED screen, thereby enhancing the cleaning effect of the cleaning robot. In addition, with the cooperation of the scraper, the water flow sprayed by the nozzle can be better evenly distributed on the screen and quickly scraped off, which helps to improve the cleaning efficiency, reduce the retention of water stains and residues, and improve the cleaning effect and ease of operation.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] like Figures 1 to 6 As shown, an outdoor LED screen cleaning robot includes a fixed shell 2 and a steel cable 1. The steel cable 1 is connected to the left and right sides of the fixed shell 2 through a fixed joint 11. A cleaning mechanism 5 is arranged inside the fixed shell 2, a flushing mechanism 4 is arranged on the front side of the fixed shell 2, and a driving mechanism 3 is arranged on the outside of the fixed shell 2. This design solves the problem that in the prior art, cleaning of outdoor LED screens mainly relies on manual operation. Since LED screens are usually located at high places, manual climbing operation is required, which has a greater safety risk in operation, high labor intensity, time-consuming and labor-intensive, and slow manual cleaning speed, low cleaning efficiency, and easy damage to the display screen.

[0030] The driving mechanism 3 includes a driving motor 31, a driving gear 32, a driven gear 33, a transmission shaft 34 and a running rubber wheel 35. The transmission shaft 34 is arranged throughout the interior of the fixed housing 2. Both the left and right ends of the transmission shaft 34 are equipped with rotatable running rubber wheels 35. The driving motor 31 is fixed on the left side of the front surface of the fixed housing 2. The driving gear 32 is arranged on the output end of the driving motor 31. The driven gear 33 is arranged on the left side of the ring surface of the transmission shaft 34, and the driven gear 33 is meshed and connected with the driving gear. The design can drive the cleaning robot to move along the surface of the LED screen through the driving mechanism 3, which is convenient for cleaning different positions on the surface of the LED screen, and improves the convenience and efficiency of cleaning. The driving gear 32 is directly connected to the output end of the driving motor 31 to receive the power of the motor. The driven gear 33 is assembled with the left annular surface of the transmission shaft 34 and meshes with the driving gear 32, so that the power is transmitted from the driving gear 32 to the transmission shaft 34. Through the transmission shaft 34, the power is transmitted from the driving motor 31 to the walking rubber wheel 35, so that the robot is driven to move on the surface of the LED screen through the rotation of the walking rubber wheel 35.

[0031] A bearing 341 is installed at the connection between the transmission shaft 34 and the fixed housing 2. The bearing 341 is used to support the transmission shaft 34, realize the rotation connection between the transmission shaft 34 and the fixed housing 2, and reduce the friction between it and the fixed housing 2. By matching the transmission shaft 34 with the bearing 341, wear can be reduced, rotation accuracy can be improved, and stable performance of the transmission shaft 34 can be ensured during long-term use.

[0032] A plurality of groups of suction cups 351 are evenly arranged on the ring surface of the walking rubber wheel 35. The adsorption force of the suction cups 351 enables the robot to move more stably on the surface of the LED screen. When the walking rubber wheel 35 contacts the surface of the LED screen, the suction cups 351 will be adsorbed on the surface of the LED screen, which can provide additional adhesion to help the robot move better on the screen. At the same time, since the suction cups 351 provide additional adhesion, the robot is not easy to slip or move, thereby reducing safety risks. Especially when cleaning at high places or edge positions, this design can significantly improve the safety of the robot.

[0033] The flushing mechanism 4 includes a diverter 41, an infusion tube 42, a branch branch 43, a baffle 44 and a nozzle 45. The diverter 41 is installed on the front surface of the fixed shell 2. The fixed shell 2 is provided with baffles 44 on both the upper and lower sides. Multiple groups of nozzles 45 are embedded in the baffle 44. The nozzles 45 are connected to the diverter 41 through the branch branch 43. The infusion tube 42 is connected to the input end of the diverter 41. The flushing mechanism 4 can spray the cleaning liquid onto the surface of the LED screen, and can clean the dust and dirt adhering to the surface of the LED screen, so as to achieve rapid cleaning of the surface of the LED screen and improve the cleaning efficiency and cleaning effect of the surface of the LED screen.

[0034] A scraper 46 with an inclined structure is provided at the outer end of the baffle 44. The scraper 46 can be attached to the surface of the LED screen. When the robot moves, the scraper 46 can remove water stains and dirt on the surface of the LED screen, thereby enhancing the cleaning effect of the cleaning robot. In addition, with the cooperation of the scraper 46, the water flow sprayed by the nozzle 45 can be better evenly distributed on the screen and quickly scraped off, which helps to improve the cleaning efficiency, reduce the retention of water stains and residues, and improve the cleaning effect and operating convenience.

[0035] The cleaning mechanism 5 includes a cleaning roller 51, a motor 52, a driving pulley 53, a transmission belt 54 and a driven pulley 55. The cleaning roller 51 is provided with two groups, which are respectively provided at the upper and lower sides of the fixed housing 2. The right ends of the two groups of cleaning rollers 51 are equipped with driven pulleys 55. The motor 52 is provided on the right side of the front surface of the fixed housing 2. The driving pulley 53 is installed on the output end of the motor 52. The driving pulley 53 and the two groups of driven pulleys 55 are connected by transmission belts 54. The cleaning mechanism 5 can clean the surface of the LED screen and remove the dust and dirt adhered to the surface of the LED screen. The motor 52 serves as a driving source to provide power for the rotation of the cleaning roller 51. The driving pulley 53 receives the power of the motor 52 and transmits the power to the driven pulley 55 through belt transmission. The transmission belt 54 connects the driving pulley 53 and the driven pulley 55 to ensure that the power can be accurately transmitted from the motor 52 to the cleaning roller 51. The driven pulley 55 cooperates with the driving pulley 53 to drive the cleaning roller 51 to rotate. The cleaning roller 51 is in direct contact with the surface of the LED screen, and the stains on the LED screen can be removed by the rotation of the cleaning roller 51 .

[0036] The cleaning roller 51 is composed of a brush 511, a roller 512 and a support shaft 513. The support shaft 513 is assembled inside the fixed housing 2 and is rotatably connected thereto. The support shaft 513 is sleeved with a roller 512 on the outside. The roller 512 is sleeved with a layer of brush 511 on the outside. The surface of the cleaning roller 51 protrudes from the rear surface of the fixed housing 2. This combined design can effectively remove stains and residues on the LED screen. The brush 511 can penetrate into the gaps on the screen surface to remove stains that are difficult to remove, and can remove dust and dirt on the surface of the LED screen and adsorb them.

[0037] The working principle of the outdoor LED screen cleaning robot is as follows: in actual use, firstly, the upper end of the steel cable 1 is connected to the external winding and hoisting equipment, and the winding of the steel cable 1 is controlled by the winding and hoisting equipment to realize the control of the lifting and lowering movement of the robot, and the infusion tube 42 is connected to the external cleaning liquid delivery equipment, and the robot is attached to the surface of the LED screen through the steel cable 1, and supported by the running wheels, and the driving motor 31 and the motor 52 are started, and the cleaning liquid is delivered to the nozzle 45 through the external cleaning liquid delivery equipment, and the cleaning liquid is sprayed onto the surface of the LED screen through the nozzle 45 to clean the dust and dirt adhered to the surface of the LED screen, and at the same time, the two groups of cleaning rollers 51 are driven to rotate by the motor 52, and the stains on the LED screen are removed by the rotation of the cleaning rollers 51. The driving motor 31 drives the transmission shaft 34 to rotate, and the transmission shaft 34 drives the running wheels to rotate, thereby driving the robot to move along the LED screen to clean different positions on the surface of the LED screen. When the robot moves, the scraper 46 can be attached to the surface of the LED screen to remove water stains and dirt on the surface of the LED screen, thereby enhancing the cleaning effect of the cleaning robot. In addition, with the cooperation of the scraper 46, the water flow sprayed by the nozzle 45 can be better evenly distributed on the screen and quickly scraped off, which helps to improve the cleaning efficiency, reduce the retention of water stains and residues, and improve the cleaning effect and operating convenience.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here.
