A road safety early warning device

Abstract

The invention discloses a highway safety early warning device, which comprises a road surface groove and a side chamber arranged on the ground, the road surface groove and the side chamber are respectively arranged on both sides of the road guardrail, and the road surface groove and the side chamber are jointly rotatably connected with a Roller shaft, the part of the roller shaft located in the road surface groove and the side cavity is fixedly connected with a roller and a driving gear respectively, the driving gear is meshed with a driven gear, and a centrifugal plate is fixed on the lower end surface of the driven gear , the centrifugal plate is rotatably connected to the lower wall of the side chamber. The advantage is that in the present invention, when the speed of the vehicle on the road is low, the roller drives the centrifugal plate to rotate at a low speed. At this time, the centrifugal force on the piston cannot drive it to move to the edge of the centrifugal plate, so the vertical bar is at a low position and does not interfere with When the red light touches, only the green light is on in the display cavity at this time, indicating that the driver of the vehicle has a normal speed and can continue driving.

Description

technical field [0001] The invention relates to the technical field of highway speed limit, in particular to a highway safety early warning device. Background technique [0002] At present, the car has become a relatively popular means of transportation. During driving, the speed limit is directly related to public safety; while the driver is driving, he will ignore the situation in front of the car when checking the speedometer, which is likely to cause danger; On the other hand, more roads do not have speed limit signs. Even if the speed limit signs usually only appear at intersections, they are easily ignored. Therefore, in many cases, drivers do not know the speed limit of the current road at all, which makes It is difficult for the driver to control the speed of the vehicle. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a road safety early warning device. [0004] In order to achieve th...
