Description
Technical field
The utility model is related to advertising technical field, more specifically, it relates to a kind of billboard.
Background technology
Billboard is generally located on both sides of the road, crossing intersection, station, pedestrian and the vehicular circulation such as around highway
The larger place of amount is used as advertising.Existing billboard is generally only that the exposed above-mentioned stream of people, the vehicle flowrate of being arranged on is larger
Place, because most of Vehicular exhausts passed through are heavier, greasy dirt content is high in vehicle exhaust, and contamination is difficult at billboard surface
To clean, for attendant, the cleaning frequency of billboard can not be controlled exactly, it is preferably wide in order to play
The effect of publicity is accused, it is that to clean billboard time-consuming for the mode of highly important, traditional artificial scouring to keep billboard surface cleaning
Arduously.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of billboard, with automatic right
The advantage that billboard is cleaned.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of billboard, including
The body of rod and the billboard being arranged on the body of rod, in addition to be rotatably connected on the body of rod and receive wind with multiple wind surfaces
Power and produce the wind drive component of driving force, being had one can rotate by the wind drive Component driver, to form covering described
The cleaning assembly of the cleaning hairbrush in the cleaning face of billboard and with a lighting detecting circuit and it is controlled by illumination detection
Circuit is used to limiting the cleaning hairbrush during the day and rotated so that the clip assembly that is horizontally situated of cleaning hairbrush
Retaining mechanism.
By using above-mentioned technical proposal, during the day, clip assembly will clean hairbrush limitation, cleaning hairbrush is in water
Flat position and it can not rotate, therefore cleaning hairbrush will not block the content on billboard, reduce cleaning hairbrush and people are seen
See the influence of advertisement；And at night, clip assembly releases the restriction effect to cleaning hairbrush, cleaning hairbrush can freely turn
Dynamic, if blowing air over, wind surface, which receives wind-force, drives wind drive component to produce driving force, and wind drive component drives cleaning hair
Brush is rotated, because hairbrush forms the cleaning face of covering billboard during rotation, therefore can be to the whole of billboard
Surface is cleaned, it is achieved thereby that being cleaned to keep sign board surface cleaning to billboard automatically.
The utility model is further arranged to：The wind drive component includes being rotationally connected with the rotating bar of the body of rod
With multiple vanes for being arranged on the axis distribution on the body of rod and around the body of rod.
By using above-mentioned technical proposal, each vane has the wind surface of a reception wind-force, so as to blow air over
When vane can drive rotating bar rotate produce driving force.
The utility model is further arranged to：The vane includes being fixed on support bar and the fixation of the rotation boom end
In the support bar and cambered surface around the rotating bar circumferentially distributed arc wind-engaging part.
