Friction nano-generator and test device

Abstract

The embodiment of the invention provides a friction nano-generator and a test device. The generator is applied a space between the track and roadbed slab of a railway system and is installed at the midpoint of a rail section between every two adjacent sleepers. The friction nano-generator comprises a layered structure and an insulating waterproof packaging protection layer wrapping the layered structure; the layered structure comprises an upper supporting layer, an upper electrode layer, a friction pair, a lower electrode layer, a lower supporting layer and a buffer layer distributed sequentially from top to bottom. Mechanical energy generated by the vibration of the track and the roadbed slab when a train passes is collected; the mechanical energy is converted into electric energy to be stored or directly supplied to electric equipment related to the track. The test device provided by the invention can be used for researching the electric signal output performance of the friction nano-generator under different track vibration conditions and different friction pair gap design conditions.

Description

technical field [0001] The embodiment of the present invention relates to a frictional nanometer generator, in particular to a frictional nanometer generator and a test device, especially applied between a subway track and a track plate. Background technique [0002] With the development of my country's underground rail transit construction, the operating mileage and traffic volume of subways have increased rapidly, and related operational safety issues have become increasingly prominent. The rail transit health monitoring system can monitor the operation status of the subway in real time, but the monitoring system contains a large number of sensors and related acquisition equipment, and there are still great challenges in the energy supply problem: if the traditional wired energy supply form is adopted, due to the power supply and some The distance of the sensor is far, and the cable is easy to be damaged; if the battery is used for power supply, it needs to replace the bat...
