[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, when replacing the sign, first pull the cover 201 to pull it out of the sign box 3, then turn the rotating handle 208 to drive the threaded rod 206 to rotate, and the threaded rod 206 drives the rubber pad 207 away from the sign, so as to take out the old sign, and then put the new sign on the placement plate 202. After fixing the sign, the placement plate 202 is inserted into the sign box 3 through the insertion port 6 and the slot 203. The insertion port 6 can be closed by the set cover 201 to protect the internal structure of the sign box 3. In rainy weather, rainwater is filtered through the filter net 8 and falls into the water storage tank 7 for rainwater collection. After the device has been used for a period of time, a large amount of dust and impurities will adhere to the transparent observation window 4, affecting the display effect of the sign. The cleaning is preset by the controller. Time, when the preset processing time is reached, the controller starts the electric push rod 101 to drive the rack 102 to move back and forth in the slide rail 103. Since the rack 102 is meshed and connected with the driving gear 106, the rack 102 drives the driving gear 106 to rotate during the movement, and through the mutual cooperation among the rotating shaft 105, the transmission rod 107, the transmission rod 2 108, the connecting seat 109, the cross bar 110 and the guide rod 111, the cleaning brush 112 is driven to move up and down along the guide rod 111. Since the cleaning brush 112 is in contact with the transparent observation window 4, the cleaning brush 112 is driven to clean the dust and other impurities adhering to the transparent observation window 4. At the same time, the water pump 9 is started to pump out the water in the water tank 7, and it is sprayed and cleaned through the telescopic hose 10 and a plurality of nozzles 114 to improve the cleaning effect.
