Technical Field
[0001] The utility model relates to the technical field of traffic control, in particular to a traffic signal light regulating device. Background Art
[0002] Traffic lights are lights that direct traffic movements, and are generally composed of red, green, and yellow lights. The red light is a stop signal, and the green light is a pass signal. At an intersection, vehicles and pedestrians gather, and their destinations are different, so they must obey the instructions of the traffic lights. When the red light is on, it is prohibited to go straight or turn left. Vehicles are allowed to turn right without hindering pedestrians and vehicles; when the green light is on, vehicles are allowed to go straight or turn; when the yellow light is on, vehicles must stop within the stop line or crosswalk at the intersection, and vehicles that have crossed the stop line can continue to pass; when the yellow light is flashing, it warns vehicles to pay attention to safety. The signal light is usually equipped with a shielding edge to protect the signal machine components from the influence of bad weather such as rain, sun, and wind. When the sun is strong, the reflection of the signal light is blocked to ensure the driver's clear vision. However, since traffic lights are exposed to the outside world for a long time, dust easily accumulates on the surface of the lights, and obstacles may also accumulate on the edges of the lights, making it difficult to see the color of the lights, causing pedestrians or drivers to misjudge. Therefore, traffic lights need to be cleaned to remove dust and obstacles. However, manual cleaning poses safety hazards such as electric shock and falling from heights. Utility Model Content
