Description

Technical Field

[0001] The utility model relates to the technical field of intersection safety warning, and more specifically, the utility model relates to a safety warning device for a tram intersection. Background Technique

[0002] A tram is a light urban rail transit that is electrically driven and runs on tracks. Generally, a train has no more than five carriages. Trams are electrically driven and the vehicles do not emit exhaust gas, so they are a pollution-free and environmentally friendly means of transportation. However, since they run on the street, they occupy road space. Warning devices are usually required at tram intersections to warn passers-by that there is a tram intersection ahead and to pay attention to safety. Currently, warning signs are installed on pillars to warn passers-by. However, the angles of the existing warning signs are fixed and cannot be adjusted according to the situation of the tram intersection. For this reason, we have proposed a safety warning device for a tram intersection. Content of the Utility Model
