Description

Technical Field

[0001] The utility model relates to the technical field of identification boards, in particular to a novel cleaning mechanism for LED identification boards. Background Art

[0002] With the development of urbanization, there are more and more various signboards in cities, including highway signboards, traffic safety signboards, building number signboards, etc. With the development of LED lighting technology, LED has been widely used as the light source in current signboards due to its good luminous effect, long service life, energy saving and environmental protection.

[0003] Patent No.: CN217133944U, proposes a new type of LED signboard, which has the advantages of being able to adjust the angle of the signboard and clean the surface of the signboard, etc., which solves the problem that the angle of the LED signboard on the market cannot be adjusted, which is inconvenient for staff to use, and the existing signboard does not have a cleaning function. After long-term use, dust will affect the display effect of the signboard, and the practicality is poor.

[0004] During the implementation of the scheme, the scheme starts the second servo motor to make its output shaft drive the threaded rod to rotate, so that the two cleaning plates move relative to or away from each other, thereby cleaning the display surface of the LED sign body, and at the same time starts the water pump to spray the cleaning water inside the water tank onto the display surface of the LED sign body through the spray plate and the nozzle. However, the sprayed water will gather inside the cleaning frame, and the threaded rod is located inside the cleaning frame, which causes the threaded rod to be immersed in water. Since the threaded rod drives the cleaning plate by rotating the surface thread, the anti-oxidation layer on the surface of the threaded rod is worn, causing the inside of the threaded rod to directly contact the outside world. At the same time, since the threaded rod is immersed in water, the rust of the threaded rod is further increased, and the threaded rod will get stuck when it rotates, which makes the two cleaning plates unable to move, causing the device to be damaged and unable to clean the display surface, thereby affecting the use of the device. For this reason, a new cleaning mechanism for LED signboards is proposed to solve the above problems. Utility Model Content

[0029] By setting the water hose 9, when the slide bar 5 moves, the pressure pump transports the water inside the water tank 3 to the inside of the slide bar 5 through the water hose 9, and finally the water inside the slide bar 5 is sprayed out through the mesh 16 to spray the surface of the sign 4, thereby further improving the cleaning effect of the surface of the sign 4 and avoiding the situation where the water is sprayed from a fixed place without moving, thereby further improving the spraying effect.
