Description

Large-scale articulated bus road energy harvesting system Technical Field The utility model belongs to the technical field of energy collection, and particularly relates to a large hinged public transportation road energy harvesting system. Background The road sensing equipment is a key equipment for monitoring road conditions in real time by utilizing advanced technology and mainly comprises a road surface condition sensor. The sensors can measure various road surface parameters such as road surface temperature, state (dry, wet, accumulated water and the like), water film height, ice layer thickness, snow thickness and the like, and provide reliable data sources for management staff. The road surface condition sensor is widely applied to various traffic scenes, including expressways, urban roads, bridge tunnels and the like, and can be combined with an intelligent traffic management system to realize real-time monitoring and early warning of road conditions, ensure traffic safety and the like. The road sensing equipment mainly relies on traditional battery or urban power grid power supply, and traditional battery power supply needs to be changed when battery electric quantity is exhausted, and the urban power grid power supply needs to be connected with a 220V power line, so that the power supply is stable and reliable, but reliability and stability of a power supply line need to be considered, and the road sensing equipment is limited in use. The road sensing equipment has the problems of difficult power supply, high cost, complex maintenance, environmental pollution and the like. Therefore, how to reliably and conveniently supply power to the road sensing devices becomes a problem to be solved. Under the background, as the vehicle runs on the road, gaps exist among the structures of the vehicle, and the vehicle is easy to vibrate when the road surface is uneven or impacted during running, especially for large-scale automobiles such as large-scale hinged buses and large-scale trailers. These vehicles vibrate during running, resulting in energy loss, and such vibrations not only cause damage to the vehicle, but also apply impact force to the road surface, resulting in fatigue of the road surface material, and acceleration of breakage and aging of the road surface. For a long time, the problems of cracks, potholes and the like can occur on the road surface, and the service life and the driving safety of the road are affected. Because the energy generated by the vibration is large, if the vibration energy can be effectively utilized, the method has good practical significance for saving resources, so that the mechanical energy generated by the vibration is used for generating power to supply power for the road sensing equipment, and a solution idea for simply, stably and efficiently supplying power for the road sensing equipment is provided for researchers. Therefore, it is important to develop an energy harvesting system capable of utilizing vehicle vibration energy.
