Embracing type electromagnetic energy harvester for bridge stay cable damper
The invention discloses an embracing type electromagnetic energy harvester for a damper, belongs to the field of vibration energy harvesting, and aims to convert damper movement caused by wind-induced bridge/stay cable vibration into available electric energy. The device comprises a damper fixing clamp, a pressing rod assembly, a transmission shaft, a linear bearing, a ball screw, a gear, a coupler, a permanent magnet generator and the like. According to the working principle of the device, when environmental wind and the bridge/stay cable generate a fluid-solid coupling effect, the piston rod of the damper and the hydraulic cylinder generate relative motion so as to reduce the wind-induced vibration amplitude of the bridge/stay cable, and the relative motion of the piston rod and the hydraulic cylinder serves as external excitation; the permanent magnet generator is driven through all stages of transmission mechanisms in a rotation speed ratio increasing mode, and wind-induced vibration energy is converted into electric energy. The device has the advantages of being convenient to mount and dismount and free of interference on work of an existing damper, and can be widely applied to bridge/stay cable dampers in windy scenes such as canyons and mountains for energy harvesting power generation.
本发明公开了一种用于阻尼器的怀抱式电磁俘能器，属于振动能量俘获领域，目的是将风致桥梁/斜拉索振动引起的阻尼器运动转化为可利用的电能。本装置组成包括阻尼器固定夹具、压杆组件、传动轴、直线轴承、滚珠丝杠、齿轮、联轴器、永磁发电机等。本装置工作原理：当环境风与桥梁/斜拉索发生流固耦合作用时，阻尼器的活塞杆与液压缸发生相对运动以降低桥梁/斜拉索风致振动幅值，本装置利用二者的相对运动作为外部激励，通过各级传动机构和提高转速比方式驱动永磁发电机实现将风致振动能转换为电能。本装置具有便于安装拆卸和不干扰现有阻尼器工作的优点，可广泛应用于峡谷、山川等多风场景下的桥梁/斜拉索阻尼器进行俘能发电。
