Title:
TRACKSIDE ENERGY HARVESTING POWER GENERATION AND ENERGY STORAGE SYSTEM AND POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/267102
Kind Code:
A1
Abstract:
A trackside energy harvesting power generation and energy storage system and a trackside energy harvesting power generation method. The trackside energy harvesting power generation and energy storage system comprises a track fixing fixture (3), a power generation column assembly (1), a solar panel (4), an electric energy conversion storage assembly (2) and a flexible connecting line (5). The theory of mechanical resonance is applied to the system. When a vehicle passes along a track, the power generation column assembly (1) vibrates with the track, sleepers and roadbed, and a compression spring and a rubidium magnet (1-6) in the power generation column assembly (1) resonate with the vibrations of the track. The rubidium magnet generates the maximum up and down displacement. A coil (1-8) cuts magnetic field lines, and then AC electric energy is generated. The flexible connecting line (5) is electrically connected to the electric energy conversion storage assembly (2), and transmits the AC electric energy to the electric energy conversion storage assembly (2). When the vibrations are insufficient, solar energy is used to supplement power generation, and the energy is converted and stored in a lithium battery to achieve continuous and effective power supply.
