A kind of above-mentioned Expressway Road direction board with self-cleaning function, collection bucket 9 can collect rainwater or snowflake simultaneously
Rainwater is stored in the storage box 10, when there are vehicle at daytime or night by direction board 1, luminance sensor 8 is able to detect that certainly
Hot light or car bulb simultaneously will test signal and pass to processor 15, pass to host computer 16, that night after the processing of processor 15
On when not detecting car bulb, illustrate that host computer 16 is given according to this detection signal at this time without automobile by direction board 1
Slave computer 17 sends control instruction, and slave computer 17 is acted according to instruction control water pump 20, decelerating motor 7, and the rotation of water pump 20 will deposit
Rainwater in storage box 10 is delivered in water delivery box 12 by water-supply-pipe 11 and sprays 1 surface of directive direction board from nozzle 13, with this
Meanwhile the rotation of decelerating motor 7 drives shaft 6, mounting ring 5 and 6 rotation around the shaft of long brush holder support 3, whisk broom bar 4, scrub direction board 1 is just
Face（When specific scrub, 1 front of long brush holder support 3 and 4 alternate rotation of whisk broom bar scrub direction board, therefore only need to control two decelerations
Motor 7 starts one at regular intervals, since this control method has disclosed, belongs to the prior art, herein need not
It repeats）, when having vehicle to occur suddenly during long brush holder support 3 and 4 rotary scrubbing of whisk broom bar, luminance sensor 8 is able to detect that
The light signal of vehicle, the signal that host computer 16 is detected according to luminance sensor 8 sends control instruction to slave computer 17, the next
Machine 17 stops working according to instruction control decelerating motor 7 and water pump 20, and after passing through to vehicle, luminance sensor 8 can't detect lamp
Optical signal, water pump 20 and decelerating motor 7 work under the control of slave computer 17.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
