The invention discloses a road sign device with a self-cleaning function, which comprises a mounting column, an air collecting box is fixedly arranged at the upper end of the mounting column, a flat elastic air bag is fixedly arranged on the side, away from the mounting column, of the air collecting box, and a road sign plate is fixedly arranged on the side, away from the air collecting box, of the elastic air bag; a first one-way valve is arranged on the side edge of the elastic air bag and leads to the interior of the elastic air bag from the outside, a second one-way valve is arranged between the elastic air bag and the air collecting box and leads to the interior of the air collecting box from the interior of the elastic air bag, and vertically-arranged sliding cavities are formed in the two sides of the road sign plate, a piston block is arranged in the sliding cavity in a sliding and sealing mode, and a gas collection box communicates with a gas guide pipe through a pressure valve. According to the road sign device, the elastic air bag is arranged between the road sign body and the mounting column, the elastic air bag plays a good role in buffering and damping, and when the road sign body is suddenly stressed by external force, impact at the joint of the mounting column and the air collecting box is relieved.
本发明公开了一种具有自清洁功能的路标装置，包括安装柱，所述安装柱上端固定配置有集气箱，所述集气箱远离安装柱的一侧固定配置有扁平状的弹性气囊，所述弹性气囊原来集气箱的一侧固定配置有路标牌，所述弹性气囊侧边配置有第一单向阀，所述第一单向阀由外部通向弹性气囊内部，所述弹性气囊与集气箱之间配置有第二单向阀，所述第二单向阀由弹性气囊内部通向集气箱内部，所述路标牌两侧内开设有垂直设置滑动腔，所述滑动腔内滑动密封配置有活塞块，所述集气箱通过压力阀连通有导气管。本发明在路标牌与安装柱之间设置弹性气囊，弹性气囊起到了良好的缓冲减震效果，当路标牌突然受到外力时，安装柱与集气箱之间连接处的冲击得到减缓。
