Automatic adjustment deceleration strip with vehicle speed identification function

Abstract

The invention discloses an automatic adjustment deceleration strip with a vehicle speed identification function. The automatic adjustment deceleration strip comprises a deceleration strip panel, an adhesive cylinder and a piston plate, wherein one end of the deceleration strip panel is movably fixed on the ground, and the other end of the deceleration strip panel is in contact with the ground through an elastic part; a connection rod is fixed on the deceleration strip panel; the non-fixed end of the connection rod is provided with the piston plate; water permeation holes are formed in the piston plate; the adhesive cylinder is fixed in a groove in the ground; the adhesive cylinder is filled with liquid; the piston plate can do perpendicular motion in the adhesive cylinder; the liquid can only overflow or flow back to the adhesive cylinder through the water permeation holes. The automatic adjustment deceleration strip has the advantages that the stopping force of the deceleration strip can be adjusted and controlled according to vehicle speeds, and the deceleration strip can be self-adjusted to adapt to different traffic environments.

Description

technical field [0001] The invention designs traffic safety facilities, relates to the field of new special facilities for traffic safety, and in particular relates to an automatic speed reduction belt with the ability to recognize vehicle speed. Background technique [0002] Judging from the effect of speed bumps in recent years, speed bumps are a double-edged sword. Speed ​​bumps can effectively improve road traffic safety conditions, on the contrary, they may have little effect or even become artificial roadblocks on the road. Most of the current speed bumps make the road surface arched to achieve the purpose of vehicle deceleration. However, when the vehicle passes the speed bump, there will be violent vibration without exception, and the feeling of discomfort and insecurity will arise spontaneously. [0003] There is already a noise reduction hydraulic speed bump device design in China. The purpose of using hydraulic design is to reduce the noise pollution generate...

Problems solved by technology

However, this design has too high requirements on the spring. The spring bears a lot of pressure when the deceleration belt is pressed down. When the deceleration belt rises and returns to its original position, the liquid on the upper part of the piston plate completely relies on the spring to release the elastic potential energy and presses back to the lower part. It is known that the process of liquid passing through the permeable hole is slow, requiring the spring to continuously and strongly squeeze the liquid

The hydraulic device can indeed slow down the descent speed during the descent of the speed bump, but its structure also prevents the speed bump from being reset in time, and the slow ascent process may cause the speed bump to be unable to exert any binding force on the following vehicles

At the same time, the existing hydraulic speed bumps have high requirements on the airtightness of the hydraulic device, making it difficult to realize

Existing speed bumps do not have the ability to distinguish the speed of driving vehicles, and cannot reduce the vibration of low-speed vehicles while maintaining punitive vibrations for high-speed vehicles
