Description
Technical field
The present invention relates to display device technical field, it is more particularly related to a kind of open air dedusting display screen.
Background technology
Outdoor display screen is exposed in natural environment, and experience is exposed to the weather, dust adheres to, rainwater spray, is very easy to product
Tired dust and rainwater, the especially display screen installed in roof or high building side, bear larger wind-force, dust or haze
During through display screen, it is easily adhered in the front of display screen, causes display screen to obscure；Equally, the airborne dust of road is very big, roadside
Display screen is also easy to dust accumulation and influences display effect.Due to the influence that dust accumulation and rainwater spray, outdoor display screen needs frequent
Safeguard, heavy workload is of high cost.
Outdoor display screen towers in natural environment, if it is possible to and continue adsorption compression dust, dust is separated with air,
It is able to will contribute for air purification.
Therefore there is an urgent need for design one kind can clear up dust automatically, and the outdoor dedusting for reducing frequency of maintenance and purification air is shown
Display screen.
The content of the invention
It is an object of the invention to solve at least the above defect, and provide the advantages of at least will be described later.
In order to realize these purposes and further advantage according to the present invention, the present invention provides a kind of outdoor dedusting display screen,
Wherein, including：
Rectangular frame, it is spliced to form by four, upper and lower, left and right moulding, and the moulding is hollow structure and every moulding
Interconnect so that the rectangular frame is internally formed overall channel, the first groove, second are disposed with the inside of the moulding
Groove and the 3rd groove.
Plate windward, it is plate transparent made from glass or resin, the size of plate windward and the rectangular frame
Matching, the plate windward is arranged in the rectangular frame and the side of plate is fitted in first groove windward, described to meet
Central raised the formation wave crest or wedge angle of aerofoil, and the thickness of the plate windward from middle part, successively decrease so that institute to the left and right by two sides
The front for stating plate windward forms cambered surface or inclined-plane, the wave crest or wedge angle positioned at it is described windward on the vertical center line of plate so that
Blow between first groove there is air feed or water to lead in the positive wind of plate windward toward both sides point, the positive of the plate windward
The first gap crossed.The medium line dimpling of plate windward, when big wind can be along the surface of plate windward toward both sides when windward on plate
Walk, the dust carried secretly in wind, or be adhered to the dust windward on plate can also enter with the wind in the first gap, wind passes through first
Gap is entered in first passage, if wind-force is little, most of dust meeting cake filtration is in first passage, and remaining wind
Power can be entered in second channel by the stomata on cylinder, be then discharged, and when rainy, rainwater can be by these dusts along institute
State cylinder to be punched into the first water tank, therefore such structure plays the role of filtering dust.If wind-force is excessive, dust
It can walk downward, can also enter in the first water tank, the liquid in water tank can equally retain dust along cylinder with strong wind.
