Hydraulic buffer road isolation strip device

Abstract

The invention belongs to the technical field of road safety equipment, and particularly relates to a hydraulic buffer road isolation strip device. The hydraulic buffer road isolation strip device comprises brackets, collision rollers, hydraulic dampers and piezoelectric power generation devices, wherein each of the collision rollers comprises a rubber cylinder and a mounting bearing; each of the piezoelectric power generation devices comprises a rubber pad laid on a road surface, a power generation transmission column fixed to the lower side of the rubber pad, a fixed disk, piezoelectric sheets distributed in the radial and circumferential direction inside the fixed disk, a main gear and a pinion; sawteeth are arranged at the lower end of the power generation drive column; the sawteeth are engaged with the teeth of the pinion; one end of each piezoelectric sheet is fixed on the fixed disk, and the other end of the corresponding piezoelectric sheet is engaged with the teeth of the main gear; the fixed disk is fixed on the road; when a tire rolls over the rubber pad, the power generation drive column moves downward to drive the pinion and the main gear to rotate, so that the non-fixed ends of the piezoelectric sheets swing, and the piezoelectric sheets are bent and discharge electricity. The hydraulic buffer road isolation strip device disclosed by the invention is capable of converting the kinetic energy of an automobile running on the road surface into electric energy and capable of cushioning automobile crash.

Description

technical field [0001] The invention belongs to the technical field of road safety equipment, and in particular relates to a hydraulic buffer road barrier device. Background technique [0002] The road separation belt is to separate the left and right traffic lanes. Now it is generally a green belt. When a traffic accident occurs, it is easy to hit the railing or separation wall of the green belt, causing damage to the car. Especially on the highway, when the speed of the vehicle hits the railing and the separation wall on both sides of the road, it is easy to cause greater damage to the vehicle. [0003] Especially on highways, in order to ensure the power consumption of street lighting, etc., it is necessary to erect poles and cables in a large area, and the power supply cost is high; in order to maintain and sprinkle water on the road, the sprinkler needs to drive from one high-speed entrance to another high-speed exit. If the water in the car compartment is used up, it ...
