Stably suspended flying type bridge detection data collector

Abstract

The invention relates to the technical field of bridge detection, in particular to a stable-suspension flying type bridge detection data collector which comprises a double-wing aircraft, a data acquisition module is mounted at the top of the double-wing aircraft, and the data acquisition module comprises a stable suspension mechanism, a roller type walking mechanism, a data acquisition mechanism and a controller. The controller is electrically connected with the data acquisition mechanism, and wireless data transmission is carried out between the data acquisition mechanism and a corresponding sensor mounted at a data acquisition point at the bottom of a bridge. Through the magnetic repulsive force of a first magnet on the rotating disc and a second magnet on the roller type walking mechanism, the two corresponding roller assemblies in the set flight path direction can move in the mode of being attached to the bottom of the bridge, and it is guaranteed that the rollers always move in the mode of being attached to the bottom of the bridge in the flight process; longitudinal limiting of the whole unmanned aerial vehicle in the flight detection process is achieved, and therefore the flight detection stability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a floating-type bridge detection data collector with stable suspension. Background technique [0002] As a large-scale civil engineering structure, the bridge structure is inevitably damaged during the service period due to loads, fatigue corrosion, material aging, lack of timely maintenance and excessive traffic, which affects the service life and even leads to sudden accidents. disaster. Generally speaking, the data to be collected for bridge inspection mainly includes the appearance data of the bridge structure and the data of the mechanical properties of the bridge structure. The appearance inspection of bridges mainly relies on bridge inspection engineers to make judgments by observing the surface of the bridge structure with the naked eye, while the inspection of the mechanical properties of the bridge structure is to analyze the response of the bridge structure u...

Problems solved by technology

[0005] In view of the above problems, the present invention provides a suspended and stable flying bridge detection data collector, which uses the roller assembly to stick to the bottom of the bridge and moves along the direction of the set flight track for detection, and the two high-definition cameras are synchronized at the image collection point Rotation solves the problem that the UAV system cannot keep the UAV system stably suspended under the bridge or fly along the bottom of the bridge, which is not conducive to the stable and efficient collection of receipts by the UAV system, and cannot fully obtain the data at the image collection point. In the real situation, the problem of not being able to analyze and judge the bridge structure at the image collection point very well
