The invention relates to an unmanned flight device for logistics distribution and with a rainproof function. The device comprises a main device body and at least two flight mechanisms; the unmanned flight device further comprises a storage mechanism and a bird dispelling mechanism, the storage mechanism comprises a containing groove, a lifting ring, a waterproof membrane and four supporting assemblies, and the bird dispelling mechanism comprises a fixation shaft, a rotary plate, an annular gear, a driving assembly and two ultrasonic bird dispelling devices; each supporting assembly comprises asupporting rod, a moving block, an elastic rope and a driving unit. According to the unmanned flight vehicle for logistics distribution and with the rainproof function, through the arrangement of thestorage mechanism, the waterproof membrane is collected and stored, under the protection function of the protection membrane, the probability that goods are wetted by rainwater is lowered, and thus the practicability of a drone is improved; through the bird dispelling mechanism, the ultrasonic bird dispelling devices are driven to rotate, the bird dispelling range of the ultrasonic bird dispelling devices is expanded, and thus the probability that the drone collides with birds is reduced.
