Self-cleaning windproof self-falling type LED advertising board device

Abstract

The invention relates to the related field of LED screens, and discloses a self-cleaning windproof self-falling type LED advertising board device which comprises a main box, a cleaning lead screw cavity with a forward opening is formed in the main box, a torsion spring cavity is formed in the right side of the cleaning lead screw cavity, and an auxiliary conveying belt cavity extending downwards is formed in the left side of the cleaning lead screw cavity. A motion switching cavity located on lower side of cleaning lead screw cavity is formed in right side of auxiliary conveying belt cavity, and a steering bevel gear cavity is formed in right side of motion switching cavity. The outdoor wind speed is monitored through the wind wheel, and the lifting effect of the lifting lead screw is achieved, so that automatic descending of the LED advertising board in strong wind weather is achieved. And thus the potential safety hazard caused by the LED advertising board in strong wind weather is reduced. After the wind stops, the device rises automatically to ensure normal use. Moreover, the cleaning sponge is driven by the cleaning lead screw in the device to reciprocate on the LED display screen, self-cleaning of the LED display screen is achieved, and potential safety hazards brought by manual cleaning are avoided.

Description

technical field [0001] The invention relates to the related field of LED screens, in particular to a self-cleaning windproof and self-falling LED billboard device. Background technique [0002] In order to achieve the best advertising effect, most of the current outdoor LED billboards will be installed in higher positions. However, such billboards are easily affected by strong winds. Due to the large wind area of ​​LED billboards, Therefore, it is easy to be affected by the wind and cause screen damage or even collapse caused by damage to the supporting structure. Therefore, the current LED billboards have certain safety hazards. At the same time, due to the high position of the LED billboards, it is difficult to clean them. And there will also be greater potential safety hazards through manual cleaning. Contents of the invention [0003] The purpose of the present invention is to provide a self-cleaning windproof self-falling LED billboard device, which can overcome the ...
