Problems solved by technology

However, because the technology protected by this patent fails to organically combine the power generation device with the pavement structure, it is necessary to dig deep pits on the road surface first to install his device, which will cause great damage to the pavement structure of the roadbed. This makes his system unable to be laid continuously over long distances, and also poses certain safety hazards

Embodiment Construction

[0063] see Figure 1-8 , according to the technical solution of the present invention, the technical route of the first embodiment is: for the flexible pavement represented by asphalt pavement, if it is directly laid during road construction, after the roadbed, pavement cushion and base layer are laid, the pressed The electric device is laid in the pavement surface layer; a layer of piezoelectric device can also be laid on the old road before the overlay or wear layer is laid. Piezoelectric devices can be laid on the entire road, or in strips according to the lateral distribution of wheel tracks, such as figure 2 shown. figure 2 The layers from top to bottom are 5 asphalt wear layers, 6 piezoelectric devices, 1 asphalt surface layer, 2 base layer, 3 cushion layer and 4 roadbed.

[0064] image 3 The structure of the piezoelectric device in the first embodiment is given. The device is composed of an insulating layer 7 and a piezoelectric stack 8 . When the vehicle passes...

Abstract

This invention discloses a piezoelectric generation method by road system vibration energy and a system, which lays the piezoelectric device in the road or as the road component part to generate electric energy by vibration energy to be stored or utilized, including: at least one piezoelectric device set in the road concerting vibration energy to electric energy, a power transformation device for regulating and converting the energy generated by the piezoelectric device and using the energy in a storage device, an energy storage device used for storing energy regulated by the transforming device, said piezoelectric device is connected with the transforming device, which is connected with the energy storage device.

Description

technical field [0001] The invention relates to a method and a system for generating electricity in a road system, in particular to a method and a system for generating electricity by using vibration energy of a road system piezoelectrically. Background technique [0002] Energy sources that can be used to generate electricity typically include wind, hydro, solar, nuclear, and steam. With the increasing requirements for energy efficiency and preservation, the development of environmentally friendly and pollution-free new energy sources has become a hot topic in scientific research. Vehicles inevitably bring pressure and impact to the road during driving. This part of energy not only produces vibration and noise, but also affects ride comfort and road life. In order to turn waste into treasure and recycle road energy, predecessors have developed Some systems and methods. [0003] These systems can generally be divided into mechanical systems, pneumatic systems, and hydrauli...
