Amphibious power propulsion device suitable for sea and air and multi-axis aircraft

[0026] Such as figure 1 and figure 2 As shown, a power propulsion device suitable for sea and air amphibiousness includes a frame-type cage 5, a power motor 6 fixedly arranged in the middle of the cage 5, a propeller shaft 7 rotatably installed on the cage 5, and the power motor 6 power is transmitted to the transmission gear set 4 and the tilting motor 12 of the propeller shaft 7, one end of the propeller shaft 7 is connected with the propeller 1 for space through a one-way bearing, and the other end is fixedly provided with the propeller 9 for water, and the single The rotating mechanism is a one-way bearing, the bearing inner ring of the one-way bearing 3 is fixedly connected with the propeller shaft 7, and the bearing outer ring of the one-way bearing 3 is fixedly connected with the empty propeller 1, wherein the empty propeller 1 is The propeller made of nylon has a radius of 11 inches and a propeller angle of 45 degrees; the water propeller 9 is a fully immersed propelle

[0032] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the power motor 6 is a biaxial motor, and the two output shafts pass through the cage 5, and the empty propeller 1 is connected to one of the output shafts through a one-way rotation mechanism. Connected, the water propeller 9 is connected with another output shaft. A deep groove ball bearing 13 is arranged between the output shaft of the power motor 6 and the cage 5 . This embodiment has simple structure and reduces dead weight.

[0034] Such as Figure 3 to Figure 4 As shown, a multi-axis aircraft suitable for sea and air amphibious, including a fuselage 15, the fuselage is a waterproof cylindrical structure, can be suspended in water, two sides of the fuselage are respectively symmetrically provided with two parallel The connecting rod 14 also includes four power propulsion devices as described in the first embodiment, of course, the power propulsion device as described in the second embodiment can also be used as required. The free end of the connecting rod 14 is fixedly connected to the housing of the tilting motor 12 of the power propulsion device suitable for sea and air amphibiousness, and the four power propulsion devices are installed symmetrically, and the central axis distances of two adjacent propellers are equal.

[0035] The multi-rotor aircraft of this embodiment includes the flight work process of the air environment and the submerged work process of the underwater environment. in:
