Abstract

The invention discloses a road protective fence. The fence comprises a plurality of main piers and a plurality of auxiliary piers, each main pier and the two auxiliary piers at the two sides of the main pier form a protection unit. A deflection column is fixed to the bottom of each main pier, a base is rotatably connected to the bottom of each deflection column through a torsional spring, a rotating groove is formed in the side wall of each main pier, a motor groove is formed in the inner bottom of each rotating groove, and a speed adjusting motor is fixed to the inner wall of each motor groove. The method has the advantages that seven pigments, namely red, orange, yellow, green, blue, indigo and purple, are coated on the surface of a seven-color ribbon, the seven-color ribbon rotates, theseven-color ribbon seen by people appears to be a white light band by utilizing the visual persistence phenomenon of human eyes; when a person drives overspeed, the person is in a relatively static state with the ribbon when passing through the seven-color ribbon, the person can see a random color ribbon instead of the white color ribbon, and the color ribbon has obvious visual impact compared with the white color ribbon, so that the purpose of prompting people against overspeed is achieved.

Description

technical field [0001] The invention relates to the technical field of road facility construction, in particular to a road protection fence. Background technique [0002] Road guardrail is a kind of road isolation facility, which is set up to separate opposing traffic or separate motor vehicles, non-motor vehicles and pedestrians; it plays an important role in ensuring driving safety and reducing the degree of potential accidents; [0003] The current road guardrail only has the function of separating and has a single function. Due to the complexity of urban roads, there are different speed limits for driving on different roads, and guardrails will be set at road junctions but do not have a speed warning function. There is a limit to the speed of the vehicle when going up and down the elevated or expressway, so the driver must change the speed in time to avoid violating the rules, and the current warning signs have a poor visual impact on people, so that the driver cannot al...
