A drone inspection system for underwater bridge piers and dams

Abstract

The invention discloses a drone detection system for underwater bridge piers and dams. The drone detection system includes a hull, motors, propellers, a communication antenna, a battery box, a battery, a control box, an integrated circuit board, a floating body, a sensor, a mounting base, a mounting plate, a falling body, a stabilizer bar, rotating fan blades, a water permeable hole, a rotating motor, a mechanical arm, a camera, a junction box, a connecting rod, a stabilizing plate, a water hole and a bearing. According to the detection system, the falling body is hemispherical, and the curvature of the bottom surface of the falling body is greater than the curvature of the top surface of the falling body, so that the flow velocity of the bottom surface of the falling body is much larger than the flow velocity of the top surface of the falling body, a downward acting force is applied to the falling body by using the pressure difference, and the acting force causes the falling body to fall down, so that the falling body is stabilized at a specified position; a plurality of rotating fan blades are symmetrically fixed on the bearing, and freely rotate around the bearing, and the rotating fan blades can rotate under the impact of water flow to eliminate the impact force of the water flow.

Description

technical field [0001] The invention belongs to the field of mechanical equipment and relates to a detection tool, in particular to an unmanned aerial vehicle detection system for underwater bridge piers and dams. Background technique [0002] Most of the important structures in reservoir dam engineering and bridge engineering are composed of concrete components. During the long-term use, due to the intrusion of external factors such as wind waves, corrosion, hydraulic erosion, and temperature stress, changes in material properties, and changes in construction conditions Under the influence of many factors such as limitations, underwater concrete structures will inevitably have different problems. In order to understand the underwater environment of structures such as dams and bridges in detail, it is usually necessary to study the environment in deep water where dams and bridges are located. For detailed understanding, it is necessary to measure the underwater environment. ...

Problems solved by technology

In this way, there are problems such as small measurement range, high input cost, and difficult maintenance. The traditional manual measurement method is to manually take a boat to the designated measurement water area or measurement point, carry out manual measurement and recording, and then go ashore to complete data sorting and reporting. There are shortcomings such as low efficiency, poor safety, and human factors interfering with the accuracy of the measured value.
