Road barrier with warning function

Abstract

The invention discloses a road barrier with a warning function. The pier comprises an annular pier body, the inner bottom of the annular pier body is fixedly connected with a resonance rod; the side wall of the resonance rod is fixedly sleeved with a plurality of magnet blocks with the same magnetic pole direction, an induction coil is embedded in the inner wall of the annular pier body, an annular cavity is formed in the inner wall of the annular pier body, the inner wall of the annular cavity is slidably connected with a conductive block in coupled connection with the induction coil, and anannular vibration cavity is formed in the side wall of the annular pier body. According to the invention, the resonance rod is driven to vibrate through vibration generated in the driving process of an automobile; the induction coil moves relative to the magnet block and cuts the dynamic induction line; the induction coil generates induction current and electrifies the conductive block, so that the conductive block moves along the inner wall of the annular cavity and continuously sweeps the cavity, the permanent magnet block and the conductive block continuously generate magnetic attraction force, quick vibration of the vibrating diaphragm is promoted, sound is emitted outwards through the generation hole, and an alarm prompt is given to a driver.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a road isolation pier with a warning function. Background technique [0002] The road isolation pier is a basic traffic facility, mainly used to limit the driving and parking areas of road vehicles. [0003] Because the height of the isolation pier is generally set very short, most of the isolation pier is in the blind area of ​​the driver. For some inexperienced drivers, the car will collide with the isolation pier due to the problem of sight when driving. Or rolling, on the one hand, it will cause damage to the car, thereby causing economic losses to the driver, and on the other hand, the isolation pier will be damaged, increasing the maintenance cost of the traffic facilities. [0004] Therefore, we propose a road separation pier with warning function to solve the above problems. Contents of the invention [0005] The purpose of the present invention is to solve...
