Portable six-rotor-wing aircraft used for bridge detection

Abstract

The invention discloses a portable six-rotor-wing aircraft used for bridge detection, and relates to the field of unmanned aerial vehicles. The portable six-rotor-wing aircraft comprises an aircraft body, six foldable aircraft arm assemblies, a looking-up camera tripod head, a two-axis laser tripod head, an ultrasonic obstacle avoiding device and a retractable landing gear, wherein each foldable aircraft arm assembly is composed of a motor, a paddle, a collision preventing structure, an aircraft arm and a foldable structure. In order to achieve the purpose of bridge detection, the looking-up camera tripod head is developed and designed to be used for photographing flaw information of a bridge bottom face and bridge piers; the laser scanning range finder tripod head is designed and used for scanning bridge bottom two-dimensional features and positioning the aircraft in the bridge bottom non-GPS environment; the ultrasonic obstacle avoiding device is designed and used for avoiding obstacles for the aircraft under complex environments; the foldable aircraft arm assemblies can be folded and unfolded conveniently and quickly, so that the problem that a large-size unmanned aerial vehicle is not convenient to carry is effectively solved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a six-rotor unmanned aerial vehicle used for bridge detection. Background technique [0002] In recent years, with the advancement of new materials, micro-electro-mechanical (MEMS), micro-inertial navigation (MIMU) and flight control technologies, micro unmanned aerial vehicles (MUAVs) are developing rapidly and receiving more and more attention. As a kind of micro unmanned aerial vehicle, multi-rotor UAV has the characteristics of small size, simple mechanical structure, vertical take-off and landing, and hovering. It has a wide range of applications in military, civil, industrial, agricultural and other fields. prospect. At present, the vast majority of multi-rotor unmanned aerial vehicles use GPS for positioning outdoors, and generally use VICON and other motion capture systems for positioning and flying indoors. In the absence of GPS and external positioning, such as ...
