Abstract

The invention discloses a power taking device and an unmanned helicopter with the same and relates to the technical field of power taking of the unmanned helicopter. The power taking device and the unmanned helicopter with the same are aimed to solve the problems that a battery for the unmanned helicopter is difficult to support the long-time patrol, the load is small, and the working efficiency is greatly lowered. According to the power taking device and the unmanned helicopter with the same, a flow guide frame comprises a magnetic coupled coil, the magnetic coupled coil is capable of extracting the electric energy in a magnetic field generated by current, the magnetic coupled coil converts the electric energy into electric energy suitable for load through a capacitive circuit and a power electronic circuit, the unmanned helicopter can use the broadly existed overhead line to charge autonomously in the long-distance running, the trip, working time and load of the unmanned helicopter can be reinforced through charging autonomously by several times, and the working efficiency of the unmanned helicopter can be improved. The power taking device can take power from the overhead line, and the power taking device can charge the unmanned helicopter with the same.

Description

technical field [0001] The invention relates to the technology for unmanned helicopters to obtain electricity. Background technique [0002] Due to the relatively low energy and weight of batteries, UAVs powered by battery energy have limited battery weight. Especially in low temperature areas, the energy problem of UAVs is more prominent due to the poor charge and discharge characteristics of batteries at low temperatures. For small unmanned helicopters, the working time can often only reach tens of minutes. For the UAV line inspection method, the energy problem has become the biggest obstacle restricting its application. [0003] Overhead power lines cover a wide area, crossing areas with complex terrain and harsh natural environments. Power lines and towers are exposed in the wild for a long time, and are constantly affected by physical and natural environmental factors such as mechanical tension, cold and heat expansion, airflow vibration, lightning, rain and snow, whi...
