An unmanned aerial vehicle based on tail vertebra swinging propulsion

Abstract

The invention discloses an unmanned aerial vehicle based on tail vertebra swinging propulsion, which is composed of a pressure-resistant cabin, a tail fin and a propulsion device. The three parts areall rigid solid conjoined bodies, and force is transmitted through a U-shaped frame. A wireless switch, a temperature sensor, a water pressure sensor, a posture sensor, a power supply device and a control device are arranged in the pressure-resistant cabin; wherein the cabin front cover is threaded with the front cabin flange and sealed by a double-layer sealing ring. The canopy front cover is connected with the underwater camera through the internal thread, so that the vehicle can transmit the image signal in real time under the water. The propeller frame is connected with the front cabin flange and the propellers on both sides respectively, so as to realize the sinking and floating motion of the aircraft and the high-speed navigation; the tail cone propulsion device is connected with therear cabin flange by the tail connector, and the tail fin enables the aircraft to advance through the power provided by the biomimetic sinusoidal oscillation, and the sinusoidal oscillation tail vertebra causes the aircraft to make small-radius steering in a small range, and the motion process noise is small.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an unmanned aerial vehicle propelled by tail vertebra swing. Background technique [0002] At present, common unmanned underwater vehicles at home and abroad, such as autonomous underwater vehicles and remote-controlled underwater vehicles, mostly use traditional propellers as propellers. Propeller propulsion technology has irreplaceable advantages in practical applications, and its theoretical research and practical applications are relatively mature, but it also has its own shortcomings, such as large noise, large disturbance to the environment, poor movement flexibility and concealment, and poor application occasions. restricted. In order to improve the motion capability of underwater unmanned vehicles, people continue to study new propulsion methods, so people strive to get inspiration from colorful fish, and apply their motion mechanisms and behaviors to underwater unmanned ...

Problems solved by technology

Propeller propulsion technology has irreplaceable advantages in practical applications, and its theoretical research and practical applications are relatively mature, but it also has its own shortcomings, such as large noise, large disturbance to the environment, poor movement flexibility and concealment, and poor application occasions. restricted

Due to the addition of the flipper mechanism and the dorsal fin mechanism, although the steering function can be realized, the structure is too complicated and the sealing effect is poor, so it is difficult to swim in a large water depth
