Self-cleaning type road sign for building site

Abstract

The invention discloses a self-cleaning type road sign for a building site. The self-cleaning type road sign for the building site comprises an upright post and a sign body fixedly connected to the side wall of the upright post through a fixing plate, wherein a device cavity is formed in the side wall of the upright post, an impeller is rotatably connected to the side wall of the upper end of theupright post through a rotating shaft, and the rotating shaft penetrates into the device cavity and is fixedly connected with a permanent magnet. According to the self-cleaning type road sign for thebuilding site, the impeller, the permanent magnet, a stretchable air bag, an air outlet mechanism, a spiral coil and indicator lamp strips are arranged, so that the automatic cleaning and dust removalof the surface of the sign can be realized, and a driver can know the road conditions clearly. Meanwhile, the potential safety hazard of manual cleaning is avoided, the cleaning efficiency is improved, and the labor intensity is reduced. The indicator lamp strips can emit light to enhance the warning effect of the road sign, and the driver can be better helped to know the instruction content andcan also be attracted to actively watch the sign to know the road conditions.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a self-cleaning road sign for a construction site. Background technique [0002] The construction site of bridge engineering or highway engineering generally spans many roads, and various road signs are set up on these roads to indicate road conditions. The instructions on these road signs can help drivers quickly obtain nearby roads However, due to the heavy dust on the construction site and the long-term transportation of building materials by large trucks, these signs are often covered with more dust. The dust will cover the instructions on the signs, making it difficult for drivers to obtain them. Road conditions not only easily cause social vehicles to enter the construction site by mistake, causing unnecessary danger, but also easily cause building material transport drivers to be unable to deliver building materials to the required location in time because t...

[0002] The construction site of bridge engineering or highway engineering generally spans many roads, and various road signs are set on these roads to indicate road conditions. The instructions on these road signs can help drivers quickly obtain nearby roads However, due to the heavy dust on the construction site and the long-term transportation of building materials by large trucks, these signs are often covered with more dust. The dust will cover the instructions on the signs, making it difficult for drivers to obtain them. Road conditions not only easily cause social vehicles to enter the construction site by mistake, causing unnecessary danger, but also easily cause building material transport drivers to be unable to deliver building materials to the required location in time because they are not familiar with the road conditions

[0003] For the dust on the sign, the relevant personnel on the construction site usually arrange special personnel to clean it regularly, but because the height of the sign is generally high, it is necessary for the staff to climb to the top of the column pole during cleaning, and wipe the sign in the air Cleaning is not only cumbersome to operate, but also has certain potential safety hazards, and the cleaning staff will also affect the driver's acquisition of the content of the sign when cleaning; and because this type of construction site spans a large area, there are many such signs, so Cleaning personnel need to clean more signboards at one time, which is very labor-intensive
