Self-cleaning outdoor electronic display unit

Abstract

The invention discloses a self-cleaning outdoor electronic display device, which comprises at least two upright posts. The shell is arranged at the upper ends of at least two upright posts. The shellfurther comprises a pair of electronic display screens and two groups of wind turbine generators. A pair of cleaning assemblies are arranged on the housing, and a pair of cleaning assemblies are respectively arranged on the outer side walls of the housing adjacent to the pair of liquid crystal panels. Any cleaning assembly includes a water collecting tank; a filter net; a cleaning brush; a curvedshaft; an elastic tube; a pair of telescopic rods; a pump disposed on the elastic tube; a driving motor I driving a pair of telescopic rods to periodically expand and contract; and a single chip microcomputer. The invention can meet the requirements of rich advertisement and other information display of the business picture, and the display effect is remarkable. And the display surface of a pair of liquid crystal screens can be automatically cleaned at regular intervals to ensure the display effect and save human resources. The self-cleaning outdoor electronic display device can effectively use wind energy to power, energy conservation and environmental protection.

Problems solved by technology

In order to sell products, merchants often use various methods for advertising. At present, the application of print advertising equipment is very common. There are traditional advertising light box equipment and various electronic advertising devices. Shopping malls, stations, airports can be seen everywhere, and indoors A large number of LCD screens or touch screens are also used for advertising display and human-computer interaction, and the publicity effect is remarkable, but this is only for indoor display and advertising

If you use the LCD screen for display outdoors, although the display effect is remarkable, because the LCD screen is exposed to the outside for a long time, its surface is easy to accumulate dust or form large water stains, and it needs to be cleaned frequently. However, due to the outdoor electronic display screen Generally, it is set at a higher position, which makes manual cleaning very inconvenient, which in turn increases the cost of manual maintenance. If it is not cleaned for a long time, it will directly affect the display effect of the electronic display screen, and even affect its heat dissipation effect.

In addition, due to the long-term exposure of the electronic display screen, it is easy to damage the display screen and its supporting equipment when encountering strong winds or stormy weather, resulting in a greatly shortened service life of the display screen and its supporting equipment, frequent updating of equipment, and increased advertising costs.
