摘要：As an unconventional power supply for on-line monitoring equipment, how to arrange the electric field energy harvesting device at the tower side and ensure its structural reliability in typhoon weather is worth further discussion. From the point of view of installation practicability, this paper adopts magnetic suction device, taking into account the T-shaped and circular cross-sections and modeling them. Through fluid-solid mechanical coupling simulation, the force and deformation of the device under different airflow velocities are obtained. The expression of minimum magnet suction which can ensure that the device is adsorbed stably at the side of the tower is deduced and used as the main index to measure the reliability of the structure of the device. Compared with the two kinds of device structures, the structure reliability of T-shaped collector is difficult to meet at higher wind speed, while the cylindrical collector is more reliable even when the wind speed gets high enough.
