技术领域technical field

本发明涉及一种多模态道路压电发电装置，属于压电发电的技术领域。The invention relates to a multi-modal road piezoelectric power generation device, which belongs to the technical field of piezoelectric power generation.

技术背景technical background

道路作为最主要的交通设施，对促进经济发展和为人们生产生活提供便利起到了重要作用。改革开放以来，经济的飞速发展，促进了运输需求的持续增长，为道路工程建设的发展提供了千载难逢的机遇，同时也提高了对道路功能的要求。道路在承担交通运输功能的同时也承载着大量的环境能量，车辆轴载作用的振动能量、太阳辐射的能量、轮胎与路面的摩擦能量甚至是汽车发动机废气排出的能量均可以被回收利用，利用压电效应将道路上交通轴载振动产生的机械能转化为电能为道路交通附属设施供电是一种理想的道路环境能量收集方式。As the most important transportation facility, roads play an important role in promoting economic development and providing convenience for people's production and life. Since the reform and opening up, the rapid economic development has promoted the continuous growth of transportation demand, provided a once-in-a-lifetime opportunity for the development of road engineering construction, and also raised the requirements for road functions. The road also carries a large amount of environmental energy while undertaking the transportation function. The vibration energy of the vehicle axle load, the energy of solar radiation, the friction energy between the tire and the road surface, and even the energy discharged from the exhaust gas of the automobile engine can be recycled and utilized. The piezoelectric effect converts the mechanical energy generated by the axle-loaded vibration of the road into electrical energy to supply power to the road traffic ancillary facilities, which is an ideal way to collect energy from the road environment.
