Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The unmanned aerial vehicle of the present invention is an improvement on the basis of existing underwater unmanned aerial vehicles. figure 1 It is a schematic diagram of the overall structure of the present invention. The said autogyro underwater UAV includes a main body 1. The said main body 1 is used for carrying sensors and transporting materials. It is negative buoyancy itself. The preferred main body 1 occupies the overall structure 35-45% of the total weight, within this weight range is not only conducive to the rationality of the internal power system and power system space layout, but also conducive to the stability of navigation and avoiding excessive energy consumption due to excessive gravity. quick. A rotating shaft perpendicular to the horizontal plane is installed on the top of the head of the main body 1, and a vertica...

Abstract

The invention discloses an autonomous underwater vehicle with a rotor. The autonomous underwater vehicle comprises a main body. A rotating shaft perpendicular to a horizontal plane is mounted at the top end of the head of the main body. A vertical rudder is rotatably connected to the rotating shaft, and horizontal fixed fins are symmetrically mounted at the left and right sides of the head of the main body. A thruster is connected to the front end of the head of the main body. The autonomous underwater vehicle further comprises the rotor which comprises a mast mounted in the gravity center position of the overall autonomous underwater vehicle, two supporting legs of the mast are in left-right symmetry with respect to the longitudinal axis of the main body of the autonomous underwater vehicle, and the mast is fixedly connected with a welding part fixed to the main body through bolts. The mast is rotatably connected with a posture control lever through a rotary shaft, a rotor support is rotatably connected to the posture control lever through a rotary central shaft, and a forwarding rotor piece and a backing rotor piece are symmetrically mounted on the rotor support. The negative buoyancy and the loading capacity of the autonomous underwater vehicle are high.

Description

technical field [0001] The invention relates to an underwater unmanned aerial vehicle, in particular to a self-rotor underwater unmanned aerial vehicle. Background technique [0002] At present, the country is promoting and building the ocean observation network and the construction of underwater space stations. In the field of marine technology in the future, not only neutral buoyancy mobile observation platforms such as underwater unmanned autonomous submersibles (AUVs) are needed, but also larger The large-scale sensor carrying platform and the energy material carrying platform of the load. [0003] The traditional AUV is mainly composed of the fuselage body, horizontal fixed fins, rudder and propeller, such as the structure disclosed by the AUV independently developed by Tianjin University. Traditional AUVs are all trimmed to a near-neutral positive buoyancy state. If the buoyancy of the AUV is too high, it will be difficult to dive, and it is necessary to maintain a ba...
