Self-cleaning auxiliary prompting device for traffic signal lamp

Abstract

The invention relates to the related field of traffic signal lamps, and discloses a self-cleaning auxiliary prompting device for traffic signal lamps. The device comprises a main box body, the left end surface of the main box body is fixedly connected with a traffic lamp pole, and the main box body is internally provided with a signal cavity with an upward and forward opening. The tail end of the upper side of the side wall of the signal cavity is fixedly connected with a splitter plate, a collecting box is fixedly connected to the upper end face of the main box body, and a collecting cavity with an upward opening is formed in the collecting box. An electromagnet changes the power-on state along with changes of a signal lamp, then the position states of a fixed mark, an extending plate, a movable mark and a withdrawing sliding block are changed, and therefore a vivid prompt mark is formed, and the effect of prompting whether the people with red and green blindness can pass through or not is realized. The collected rainwater can just flow through the surface of the signal lamp while the extending plate, the moving mark and the withdrawing sliding block change the position states, the signal lamp is automatically cleaned under the rotation effect of a cleaning brush, and the potential safety hazards are reduced as much as possible.

Description

technical field [0001] The invention relates to the related field of traffic signal lamps, in particular to a self-cleaning auxiliary prompting device for traffic signal lamps. Background technique [0002] When the traffic signal lights are used for a long time or the environment is relatively bad, dust is easy to accumulate on the surface of the signal lights, which affects the function of the traffic lights and has certain potential safety hazards. On the other hand, people with red-green color blindness have When using traffic signal lights on the road, it is difficult for such people to clearly distinguish the color information of the signal lights, and the existing traffic signal lights have a relatively simple structure, which is difficult to meet the accurate use of people with red-green color blindness. Contents of the invention [0003] The purpose of the present invention is to provide a self-cleaning auxiliary prompting device for traffic signal lights, which c...
