Description

Technical Field

[0001] The present invention relates to the technical field of LED screen cleaning, and in particular to a dust removal and cleaning device for an outdoor LED screen. Background Art

[0002] As the new favorite of outdoor display advertising media in the future, outdoor LED screens are widely used in finance, taxation, industry and commerce, post and telecommunications, sports, advertising, factories and mines, transportation, education system, stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places. They have the functions of media display, information release, traffic guidance, creative display, etc.

[0003] After the outdoor LED screen has been used for a period of time, dust and impurities will be adsorbed on the LED screen. If it is not cleaned, it will have an adverse effect on the normal operation of the LED screen. In severe cases, it may even cause damage to the display screen. Therefore, the outdoor LED screen needs to be cleaned regularly to ensure the display effect of the LED screen.

[0004] When cleaning the outdoor LED screen, it is usually cleaned by a high-altitude rope (commonly known as Spider-Man) or a hanging boat. The outdoor LED screen cannot be cleaned with liquid, which is easy to cause dust and impurities to be adsorbed again. Since the dust on the outdoor LED screen is cleaned, the dust will be scattered willfully, causing environmental pollution, easily resulting in poor cleaning effects, and reducing work efficiency.
