A fixed-wing underwater drone

Abstract

The invention relates to the technical field of underwater robots and aims to provide an underwater unmanned aerial vehicle with fixed wings. Propellers are mounted on a driving shaft of a brushless motor, and the brushless motor is fixed at the front end of a fuselage; lateral wings and wing flaps are respectively composed of components which are symmetrically arranged at two sides of the fuselage, and the wing flaps are positioned at the rear sides of the lateral wings, wherein the lateral wings include a left side wing and a right side wing which are respectively fixed on the side surfacesof the fuselage, the cross section of each lateral wing is in a drop shape, and the tail end of each lateral wing faces towards the direction of the tail of the fuselage; the wing flaps include a leftwing flap and a right wing flap which are connected with a left steering engine and a right steering engine respectively through a left steering engine arm and a right steering engine arm, and the steering engines are fixed on the side surfaces of the fuselage; tail wings are connected with a rear steering engine through a rear steering engine arm, and the rear steering engine is fixed at the tail of the fuselage; and the connecting line of the propellers, the brushless motor and the tail wings is parallel to or coincident with the axis of the fuselage. The underwater unmanned aerial vehicleprovided by the invention is small in size, light in weight, simple and convenient in operation and easy to control, has no need of other auxiliary devices, has definite purposes and use values, and is convenient to popularize, and the price is low.

Description

technical field [0001] The present invention relates to the technical field of underwater robots, and more particularly refers to a fixed-wing underwater unmanned aerial vehicle. The UAV is different from the traditional way of changing gravity to achieve submersion, but uses the wings to generate potential, and is a cable-free remote-controlled robot that can navigate freely on the water surface and underwater. Background technique [0002] Underwater robot, also known as unmanned remote control submersible, is a kind of extreme operation robot working underwater. It can be mainly divided into two types: remote control submersible with cable and remote control submersible without cable. The underwater environment is harsh and dangerous, and people's diving depth is limited, so underwater robots have become an important tool for developing the ocean. In recent years, underwater robots have developed greatly both in the field of national defense and military and in the civil...

Problems solved by technology

Although this method can better meet the needs of the robot's underwater movement, there are still some disadvantages: 1) The degree of freedom of the traditional underwater robot's movement is related to the number and position of the propeller. To achieve more flexible underwater movement , you need to arrange more propellers; and increasing the number of propellers will inevitably lead to more cumbersome and complex robots, and higher costs; potential, otherwise the dive cannot be completed
