The invention relates to a wedge-shaped chargeable power grid pole tower unmanned aerial vehicle parking apron and a control method thereof. The wedge-shaped chargeable power grid pole tower unmanned aerial vehicle parking apron comprises a parking apron body erected on a power grid pole tower. The middle of the parking apron body is provided with a containing groove of which the section is in a wedge shape. The containing groove is internally provided with a charging module. The charging module is electrically connected with a voltage transformer secondary side corresponding to the power grid pole tower through a wave chopping module and a rectification module in sequence. The bottom of an unmanned aerial vehicle is provided with an electric quantity detection module. The electric quantity detection module is electrically connected with an unmanned aerial vehicle controller and arranged in a wedge-shaped shell matched with the containing groove. The charging module is electrically connected with a parking apron control unit arranged on the parking apron. The unmanned aerial vehicle controller is in data communication with the parking apron control unit through a wireless communication module. The wedge-shaped chargeable power grid pole tower unmanned aerial vehicle parking apron and the control method thereof have the beneficial effects that electric energy on the power grid pole tower can be directly adopted to charge the unmanned aerial vehicle, and a guarantee is provided for the reliable and continuous work of the power grid patrol unmanned aerial vehicle.
