The invention discloses a non-contact type intelligent rainproof device for an unmanned aerial vehicle. The non-contact type intelligent rainproof device is arranged right above the center of the multiple-rotor-wing unmanned aerial vehicle and is fixedly connected. A fan for blowing air flow upwards is arranged in a duct outer shell. The bottom face of the duct outer shell is sealed. The side periphery of the bottom is communicated with a horizontal annular transition channel which is communicated with a vertical annular air guiding channel through an annular bent channel. An opening in the top end of the duct outer shell is communicated with a drainage channel. A horizontal annular groove is formed in the side periphery of the top of the drainage channel and is used as an air outlet. A partitioning plate is arranged in the annular groove. An air curtain controller is connected with an air curtain electric regulator and a rainfall pressure sensor device. The air curtain electric regulator is connected with the fan for controlling. The non-contact type intelligent rainproof device is simple and reasonable in structure and high in universality, the problem that rainwater direct hits a machine body can be avoided, the multiple-rotor-wing unmanned aerial vehicle and avionic electronic equipment are protected, rainfall is transmitted to a ground base station for processing, a non-contact type intelligent rainproof function is achieved, and the non-contact type intelligent rainproof device has important application in flood disaster emergency processing.
