Self-cleaning device of overhead electronic advertising board

Abstract

The invention discloses a self-cleaning device of an overhead electronic advertising board. The self-cleaning device comprises a fixation frame of which two lateral side walls have openings, wherein filtering plates are symmetrically and fixedly connected on the inner wall of the fixation frame; multiple vertical rods are uniformly distributed and fixedly connected on the inner wall of the fixation frame; a permanent magnet block shaped like a wing plate is in joint slide connection to side walls of the multiple vertical rods; and a cleaning device used for cleaning the electronic advertisingboard is installed on the fixation frame. The self-cleaning device disclosed by the invention has the beneficial effects that a first air hole and a second air hole which have different hole diametersare formed, so a flowing rate of airflows on upper half parts of the filtering plates is larger than a flowing rate of airflows on the lower half parts of the filtering plates; in this way, the permanent magnet block is moved vertically back and forth on the vertical rods under lifting force and own weight, and a cleaning bar can be driven to clean dust on the surface of the electronic advertising board; and a water storage cavity is disposed, so rainwater can flow onto the surface of the electronic advertising board for cleaning.

Description

technical field [0001] The invention relates to the technical field of billboard cleaning, in particular to a self-cleaning device for high-altitude electronic billboards. Background technique [0002] Electronic advertising refers to the form of advertising that uses electronic information technology and electronic media to convey advertising information, and billboards, as an outdoor media that transmits advertising information, make electronic advertisements often spread through billboards, and in the spread of electronic billboards When the electronic billboard is often installed at a high altitude in order to obtain a better communication effect, but the electronic billboard is exposed to the outdoor environment for a long time, it will cause dust to accumulate on the surface of the electronic billboard, which will affect the display and transmission of the electronic billboard. In addition, because the electronic billboard is installed at a high place, it is very dange...

[0002] Electronic advertising refers to the form of advertising that uses electronic information technology and electronic media to convey advertising information, and billboards, as an outdoor media that transmits advertising information, make electronic advertisements often spread through billboards, and in the spread of electronic billboards When the electronic billboard is often installed at a high altitude in order to obtain a better communication effect, but the electronic billboard is exposed to the outdoor environment for a long time, it will cause dust to accumulate on the surface of the electronic billboard, which will affect the display and transmission of the electronic billboard. In addition, since the electronic billboard is installed at a high altitude, it is very dangerous to clean the electronic billboard

[0003] The existing electronic billboard cleaning device is as described in the invention patent "A Dust Cleaning Device for Electronic Billboards" with the application number "201910120346.8". Clean the outer screen of the display screen with a brush, and use filtered rainwater to clean the dust at the same time, so that the cleaning of the outside of the electronic billboard can replace manual work, and achieve the purpose of automatically cleaning the outer screen of the billboard. However, when cleaning the electronic billboard, the microprocessor needs First receive the cleaning order, and then issue an instruction to clean the surface of the electronic billboard, which requires the operator to regularly observe the degree of dust accumulation on the electronic billboard before deciding whether to clean it, which increases the work intensity, and some Electronic billboards will be set up in remote areas, so the surface of the electronic billboards will not be cleaned in time, making the display effect of the electronic billboards poor
