Traffic light applicable to severe weather environment

Abstract

The invention relates to a traffic light applicable to a severe weather environment. The traffic light comprises a base, a supporting column, a control box, a cover plate and a signal plate. An emergency device and a PLC (programmable logic controller) are arranged in a controller, and the emergency device comprises an emergency mechanism, a cleaning mechanism, a lifting plate, a lifting mechanism, a back plate and two supporting plates. The emergency mechanism comprises a rotating shaft, two rotating components and two emergency components. Each emergency component comprises a connection rodand an emergency plate. The cleaning mechanism comprises an electromagnet, a spring, a cleaning box and two direction units, and a cleaning block and a moving component are arranged in the cleaning box. The traffic light applicable to the severe weather environment has advantages that in poor-visibility severe environment weather, the lifting plate is driven to ascend by the lifting mechanism, andemergency lights on the emergency plate in the emergency mechanism are used for directing the traffic to guarantee road traffic safety; moreover, by the cleaning mechanism, cleaning and dedusting ofthe emergency lights are realized to guarantee that people can observe the emergency lights, and road traffic safety is improved.

Description

technical field [0001] The invention relates to the field of smart cities, in particular to a traffic signal lamp suitable for severe weather environments. Background technique [0002] Road traffic signal lights are a category of traffic safety products. They are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Applicable to intersections such as crosses and T-shaped intersections, controlled by road traffic signals to guide vehicles and pedestrians to communicate in a safe and orderly manner. [0003] Existing traffic lights usually use LED (light-emitting diode) as the light source of the signal light. LED has the advantages of low power consumption, small size, light weight, and long life. Weak, causing people can not see the indication of traffic lights, in this case, traffic accidents are prone to occur, making it difficult for existing traffic lights to adapt to bad weather...
