Unmanned aerial vehicle applied to bridge bottom defect detection

Abstract

The invention provides an unmanned aerial vehicle applied to bridge bottom defect detection and belongs to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle comprises a vehicle body, a remote control device, an ultrasonic probe and locating devices. Multiple rotors are installed on the vehicle body, and a flight control module and a signal transmission module are arranged in the vehicle body; the remote control device is electrically connected with the signal transmission module of the vehicle body; the ultrasonic probe is installed at the top of the vehicle body; the at least three locating devices are arranged and surround the ultrasonic probe to be installed on the vehicle body; the locating devices are suitable for making contact with the bottom of a bridge and limiting the freedom degree of the vehicle body in the horizontal direction after the ultrasonic probe makes contact with a to-be-detected piece; and the rotors are suitable for supplying upward thrust to the vehicle body all the time when the ultrasonic probe makes contact with the to-be-detected piece. By the adoption of the technical scheme, a bridge bottom detection result obtained by the unmanned aerial vehicle can be more reliable and more stable, and meanwhile the unmanned aerial vehicle further has the beneficial effects of being high in adaptability and wide in applicative workingcondition range.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle used to detect defects at the bottom of bridges. Background technique [0002] The defect detection of bridges is a necessary maintenance item that every bridge will carry out regularly every year. In the prior art, the detection of bridges generally adopts the detection method of artificial naked eyes. This method has high labor costs and will be dangerous when encountering high-altitude operations. . With the maturity of drone technology, drones are gradually applied to various fields. Therefore, some people think of using drones to inspect bridges to replace human labor. The invention patent application document with document number CN106245524A discloses an unmanned aerial vehicle system for bridge detection, by installing a main camera group and an infrared camera for collecting image data of the bridge to be detected on the unman...
