The utility model provides a transmission facility ultraviolet discharge detection device based on air travel platform, the air travel platform be many rotors flying platform, many rotors flying platform is inside from having major control system and data interface, its characterized in that: air travel platform bottom surface is equipped with a connecting plate, and video monitoring device and ultraviolet discharge detection device are equipped with to the connecting plate bottom surface, at the subaerial surface indications ware that is used for the real -time display video monitoring device field of vision that also is equipped with. The utility model discloses do not receive the restriction of the factors such as ultraviolet ray interferences in topography, weather, the sunlight, can realize measuring in all -weather 24 hours, and easy operation, sensitivity are high, have avoided measurement personnel climbing shaft tower or have been close to the transmission facility, so saved the high -risk nature that detection achievement had been eliminated simultaneously to the equipment input of climbing, also be equipped with the power transmission line and avoid the device, can make flying platform and high tension power line keep safe distance to it smashes to avoid the flying platform to be discharged by high tension power line.
