Self-energy-harvesting magnetoelectric conversion intelligent expansion joint system
A bridge self-energy-harvesting intelligent expansion joint system makes full use of the motion characteristic of reciprocating displacement at an expansion joint, magnetoelectric and piezoelectric converters are installed, and mechanical energy is converted into electric energy; the health state of the intelligent expansion joint structure can be monitored by monitoring the change characteristics of current parameters (such as voltage and current) of the intelligent expansion joint; and when the expansion joint is too wide or too narrow, reverse adjustment can be carried out by controlling the magnitude of the current. In order to guarantee the electric energy stability of the system, a'source-opening and throttling 'strategy is adopted, and a solar device and a wind power generation device are utilized to realize'source opening'. And corresponding to a power supply position, a low-power wireless distributed acquisition and transmission subsystem is adopted, so that energy transmission loss is reduced, and throttling is realized. Besides, the designed modularized magneto-electric converter can adapt to different types of expansion joints, such as a modular expansion joint and a comb tooth expansion joint, and meanwhile multi-point monitoring on uneven deformation of the expansion joints is achieved.
一种桥梁自俘能智能伸缩缝系统，系统充分利用伸缩缝处往复位移的运动特点，安装磁电和压电转换器，将机械能转换为电能；通过监控智能伸缩缝电流参数(如电压、电流等)变化特征，可以监控智能伸缩缝结构的健康状态；对于伸缩缝过宽或者过窄，可以通过对电流大小进行控制来进行反向调节。为了保障系统电能稳定，采用“开源节流”策略，利用太阳能装置，风力发电装置，从而实现“开源”。与供电位置相对应，采用低功率无线分布式采集与传输子系统，降低能量传输损耗，从而实现“节流”。此外，设计的模块化磁电转换器，可以适应不同类型的伸缩缝，如模数式、梳齿式，同时也实现了对伸缩缝不均匀变形的多点监测。
