Contact type friction power generation device based on bridge vibration

Abstract

The invention provides a contact type friction power generation device of a box girder structure. The power generation device is applied to a box girder type bridge structure, includes a plurality of contact type friction power generation units, the touch type friction power generation units are installed inside and on a lower surface of the box girder in a distributed manner, the plurality of contact type friction power generation units can be connected in series and generated electric energy vibrates with a bridge, mechanical energy of vibration of the box girder structure is collected and the collected mechanical energy is converted into electric energy which is stored or used to supply power to electric equipment. The contact type friction power generation device based on bridge vibration is installed inside and on the lower surface of a bridge structure, mechanical energy of bridge vibration caused by an environment dynamic load is converted into electric energy, and through voltage stabilization and voltage transformation processing of a power supply control integrated system in a power supply thin film device, power supply of each electric equipment on the bridge or electric energy storage is performed, thereby ensuring continuous power supply of a system, providing a brand new environment-friendly green energy for the box girder structure.

Description

technical field [0001] The invention relates to an energy capture power generation device for bridge structures. Background technique [0002] In today's environment where energy conservation and environmental protection are advocated, clean energy such as solar energy and wind energy have been widely used in transportation facilities, but limited by their size and layout requirements, they can only be used on a small scale as ancillary facilities. Therefore, there is a need for an energy supply device that can be used more widely and can be combined with the traffic facility structure itself as a part of the structure rather than a simple additional facility. [0003] Bridge structures often undergo large structural vibrations under dynamic loads. In bridge engineering design, structural optimization and additional vibration reduction devices are often used to control the structural vibration intensity, and the essence of vibration reduction devices is energy absorption dev...
