The invention discloses an underwater unmanned aerial vehicle based on four rotors. The underwater unmanned aerial vehicle comprises a body, a double-blade fixed-distance propeller component, a brushless direct current motor component, an electronic speed regulator, a signal transceiver, a controller, a sealing cover, a lithium ion polymer battery and an LED lamp strip, wherein the body is made ofacrylic materials capable of respectively bearing atmospheric pressure in the air and underwater external pressure of 10 bar, the four brushless direct current motors and the double-blade fixed-distance propellers provide power for the body, and the whole body is sealed by polytetrafluoroethylene adhesive and liquid waterproof adhesive tape, so that functions of submergence in the water and flying in the air are realized. 本发明公开了一种基于四旋翼的水下无人飞行器，包括机身、双叶定距螺旋桨组件、无刷直流电动机组件、电子调速器、信号收发机、控制器、密封盖、锂离子聚合物电池和LED灯带，机身采用能分别承受空中大气压和水下10bar外部压力的丙烯酸材料，且通过四个无刷直流电机和双叶定距螺旋桨为其提供动力，并通过使用聚四氟乙烯胶及液体防水胶带对整个机体进行密封，实现了水中下潜和空中飞行的功能。
