Embodiment Construction

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

[0017] The unmanned aerial vehicle of the present invention is an improvement on the basis of the existing underwater unmanned aerial vehicle. figure 1 It is a schematic diagram of the overall structure of the present invention. The self-rotating-wing underwater drone includes a main body 1. The main body 1 is used for carrying sensors and transporting materials, and is negatively buoyant. Preferably, the main body 1 occupies the overall structure of the drone 35-45% of the total weight, within this weight range is not only conducive to the internal power system of the main body, the rationality of the spatial layout of the power system, but also the stability of navigation and the avoidance of excessive energy consumption due to excessive gravity. quick. A rotating shaft perpendicular to the horizontal plane is installed at the top of the hea...

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 present invention relates to an underwater drone, in particular to a rotary-wing underwater drone. Background technique [0002] At present, the country is promoting and constructing the marine observation network and the construction of the underwater space station. In the future marine technology field, not only the mobile observation platform with neutral buoyancy such as the underwater unmanned autonomous submersible (AUV), but also the larger Loaded large sensor carrying platform and energy material carrying platform. [0003] The traditional AUV is mainly composed of the main body of the fuselage, the horizontal fixed fins, the tail rudder and the propeller, such as the structure disclosed by the AUV independently developed by Tianjin University. The traditional AUVs are all trimmed to a near-neutral positive buoyancy state. If the AUV is too buoyant, it will be difficult to dive, and it is necessary to maintain a balanced rudder angle and a...
