Traffic signal light with good protection performance

Abstract

The invention relates to the technical field of municipal traffic, and discloses a traffic signal light with good protection performance. The traffic signal light comprises a light pole. According to the traffic signal light with good protection performance, through the arrangement of nozzles and cleaning brushes, when signal lights need to be cleaned, a water pump is started to pump water in a water tank; the water is conveyed into a left connecting hose from a right connecting hose; the water with relatively large water pressure is conveyed into a water channel through the left connecting hose; the water is sprayed out through the three nozzles; meanwhile, electric sliding rails are started to drive sliding blocks to move to the right; the sliding blocks can drive a mounting plate to move to the right; and at the moment, the cleaning brushes and the nozzles capable of spraying the water can be used for brushing and washing display parts of the signal lights. Most dust on the surfaces of the signal lights can be cleaned up after reciprocating movement. In the cleaning process, due to the fact that the time that the mounting plate stays directly in front of the signal lights is quite short, the observation of drivers is not affected visually, and the performance of the signal lights is not affected. The effect of cleaning up dust is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal traffic, in particular to a traffic signal lamp with good protection performance. Background technique [0002] At the intersection, red, yellow, green and three-color traffic lights are hung on all sides. It is a silent "traffic policeman". At the intersection, cars coming from several directions gather here, some have to go straight, some have to turn, who should go first, this is to obey the command of the traffic lights, when the red light is on, it is forbidden to go straight or turn left, without hindering pedestrians In the case of vehicles and vehicles, the vehicle is allowed to turn right; when the green light is on, the vehicle is allowed to go straight or turn; : Motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing signal lights, direction indicator lights (arrow signal lights), lane signal lights, flashing warning lights, road and railway level crossing ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a traffic signal light with good protective performance, which has the advantages of being able to clean dust, etc., and solves the problem that traffic signal lights are commonly used at urban intersections with dense traffic, and are all exposed to the air. The air quality is poor, and there is a lot of dust in the air. After a period of time, the surface of the signal light will be covered with dust. In the case of high light intensity, the observability of the signal light will be greatly reduced, seriously affecting driving safety. Some traffic lights don't have a clearing device problem
