Quadrotor

Abstract

The invention provides a quadrotor. The quadrotor comprises a quadrotor body, wherein a supporting frame is arranged on the quadrotor body; four cross-shaped mechanical arms are arranged on the supporting frame; a propeller is arranged at the end part of each mechanical arm; a driving motor drives the corresponding propeller to rotate; an ultrasonic sensor is arranged at the top of a propeller shaft of each propeller; a pressure altitude sensor is arranged on the surface, facing the ground, of the supporting frame; a control box is arranged on the quadrotor body; a chip of an integrated controller is arranged in the control box; a protruding end is also arranged on the supporting frame; an industrial camera is arranged on the protruding end. According to the quadrotor provided by the invention, detection and patrol of cracks on a bridge can be realized automatically, so that lots of manpower and material resources can be saved; the measurement is convenient, the manufacturing cost of the quadrotor is low, and the measurement efficiency is high.

Description

technical field [0001] The invention relates to a detection device, in particular to a quadcopter. Background technique [0002] In recent years, my country's transportation industry has developed rapidly. In order to alleviate the traffic pressure, the number of urban overpasses, viaducts and bridges on all levels of roads has increased year by year. Over time, the emergence of various situations will lead to an increase in the risk factor of the bridge, such as: the increase of traffic vehicles leads to an increase in the load of the bridge, there are defects in the design process, the uneven road surface of the bridge leads to local damage due to vibration, aging of materials, bad The existence of factors such as the impact of external climate and environment. The existence of such factors leads to cracks in the bridge. If it is found that the maintenance is not timely, it will easily cause structural damage to the bridge. In severe cases, the bridge will collapse and ca...

Problems solved by technology

With the passage of time, the emergence of various situations will lead to an increase in the risk factor of the bridge, such as: the increase of traffic vehicles leads to an increase in the load of the bridge, there are defects in the design process, the uneven road surface of the bridge leads to local damage due to vibration, aging of materials, bad The existence of factors such as the impact of external climate and environment

The existence of such factors leads to cracks in the bridge. If it is found that the maintenance is not timely, it is easy to cause structural damage to the bridge. In severe cases, the bridge collapses and causes serious safety accidents. The reports of such accidents are not uncommon.

[0003] Therefore, it is very important to timely discover and take maintenance and remedial measures for bridge safety. At present, the detection method is mainly manual identification method, and the bridge is measured and recorded with the help of high-power magnifying glass and microscope. This method mainly relies on manpower, and has long measurement cycle and high cost. , strong human experience factors and other defects, and at the same time, it is necessary to use scaffolding and other equipment when assisting in the measurement. There is a large flow of vehicles in the viaduct and overpass area with a large traffic volume, which also has a great impact on the safety and efficiency of the surveyors.
