Abstract

The invention discloses a miniature anti-magnetic levitation vibration energy collector and collection method for rail transit, and belongs to the field of vibration energy collection. At present, a vibration energy collection device applied to the rail transit has the problem of low energy conversion efficiency. According to the miniature anti-magnetic levitation vibration energy collector and collection method for the rail transit, the energy collector vibrates up and down under the driving of external vibration in the vertical direction; and due to asynchronous vibration of an upper coppercoil (5) on an upper pyrolytic graphite plate (4), a lower copper coil (7) on a lower pyrolytic graphite plate (8) and a levitation permanent magnet (6), magnetic lines of force are cut, so that induced electromotive forces are generated in the coils. The energy collector disclosed by the invention has the advantages of being simple in structure and high in energy collection rate; and the self-regulation can be carried out according to the applicable environment, so that the vibration energy collection can be more effectively carried out.

Description

Technical field [0001] The invention relates to a rail transit vibration energy collection, in particular to a miniature vibration energy collector and a collection method for rail transit. Background technique [0002] Using energy harvesting technology to convert unused light energy, heat energy, mechanical energy and wind energy into electrical energy to continuously power various low-power electronic products is an important direction for energy research. As a self-sustainable micro power source, the micro vibration energy harvester can convert the mechanical energy around the system into electrical energy, plus its small size, easy to be embedded in the system, and theoretically can be used indefinitely. [0003] The existing electromagnetic vibration energy harvester is in the research stage and needs to consume a part of external vibration energy during use, thereby reducing the efficiency of vibration energy harvesting. There is a need for a more efficient energy harvestin...
