Embodiment Construction

[0025] The following examples describe the present invention in more detail.

[0026] to combine Figure 1-Figure 4 , The sea-air amphibious propeller of the present invention mainly includes a ducted propeller stator 1, an air paddle 2, an air paddle rotor 9, a ducted paddle 7, and a ducted paddle rotor 11. Ducted propeller stator 1 intermediate duct 6. The air paddle rotor 9 and the ducted paddle rotor 11 rotate coaxially, are nested on the same stator 1, and are respectively driven by corresponding coils 5, 12.

[0027] The outer wall of the second half of the duct-shaped propeller stator 1 has an inward groove, and the air paddle stator coil 12 is installed in the inward groove, and the air paddle rotor 9 provided with the air paddle rotor magnet 4 is sleeved in the air. The outer side of the paddle stator coil 12; the inner wall of the first half of the ducted propeller stator 1 has an outward groove, and the ducted paddle stator coil 5 is installed in the outward groov...

Abstract

The invention provides a sea-air amphibious propeller. It includes a ducted propeller stator, an air paddle, an air paddle rotor, a ducted paddle, and a ducted paddle rotor. The air paddle rotor and the ducted paddle rotor each fix a set of magnets, and the air paddle rotor and the ducted paddle rotor rotate coaxially. Nested on the same ducted propeller stator, the ducted propeller stator is embedded with two coils corresponding to the air paddle rotor and the ducted paddle rotor respectively. The air paddle is used for air propulsion, and the water paddle is used for underwater propulsion, and the two can work independently. When propelling underwater, the air paddle folds back and rotates at a lower speed to eliminate the resistance of the air paddle. The shaftless ducted paddle works to generate thrust; the air paddle unfolds in the air and generates thrust through rotation, and the ducted paddle Auxiliary work. The shaftless ducted propeller has good propulsion performance underwater, and the air propeller is suitable for working in the air. By combining the air propeller and the shaftless ducted propeller, efficient propulsion and free switching between underwater and air can be realized.

Description

technical field [0001] The invention relates to an amphibious propeller, in particular to an amphibious propeller suitable for sea and air. Background technique [0002] Existing amphibious vehicles include amphibious vehicles and land-air amphibious vehicles, but the development of sea-air amphibious vehicles that can navigate both in the air and underwater has been stagnant. The main technical limitation is the development of propulsion equipment. Air paddles have good propulsion performance in the air, but have low thrust and low propulsion efficiency underwater, while water paddles have good propulsion performance underwater but are not suitable for working in the air at all. Therefore, designing a propeller with good propulsion performance both in the air and underwater is of great significance to the development of sea-air amphibious vehicles. Contents of the invention [0003] The object of the present invention is to provide a sea-air amphibious propeller suitable...
