Unmanned aerial vehicle emergency safety landing device for bridge detection

Abstract

The invention discloses an unmanned aerial vehicle emergency safety landing device for bridge detection, and relates to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle emergency safety landing device for the bridge detection comprises an airframe body. A controller and a pressure sensor are arranged on the airframe. A power supply is arranged in the airframe. A connecting rod is arranged at the bottom of the airframe. A supporting seat is arranged in a first shell body. A motor is arranged on the supporting seat. A gear is arranged on an output end of the motor. Arack is arranged on one side of the gear. A first through hole is formed in the bottom end of the first shell body. A second through hole is formed in the top wall of a second shell body. A pressing plate is arranged at the bottom end of the rack. A connecting ring is arranged on the pressing plate. A groove is formed in the outer wall of the second shell body. A supporting bar is arranged in thegroove. A circular hole is formed in an adjusting rod. A notch is formed in the bottom of the second shell body. A supporting plate is arranged at the bottom end of the adjusting rod. A buffer part isarranged at the bottom of the supporting plate. The unmanned aerial vehicle emergency safety landing device for the bridge detection has the beneficial effect that the unmanned aerial vehicle emergency safety landing device can safely descend to a water surface, and the unmanned aerial vehicle can be effectively protected when the unmanned aerial vehicle detects the failure of a bridge.

Description

technical field [0001] The invention mainly relates to the technical field of unmanned aerial vehicles, in particular to an emergency safety landing device for a bridge detection unmanned aerial vehicle. Background technique [0002] With the continuous maturity and development of UAV technology, its application fields are becoming more and more extensive. In the field of bridge inspection, special drones have also appeared to take pictures of the bottom surface, cylinder, beams, stay cables and other parts of the bridge for experts to inspect, saving time and effort and making the inspection more comprehensive. However, most of the bridges are set on the river. Once the drone collides with the bridge, it needs to make an emergency landing if it fails, and it will fall into the water. In the existing technology, structures such as airbags and parachutes have appeared for the emergency and safe landing of UAVs, but these structures can only ensure that UAVs land on the groun...

Problems solved by technology

However, most of the bridges are set on the river. Once the drone collides with the bridge, it needs to make an emergency landing if it fails, and it will fall into the water.

In the prior art, structures such as airbags and parachute aids have appeared for the emergency and safe landing of drones, but these structures can only ensure that the drone lands on the ground smoothly. When the drone is in the process of bridge inspection During an emergency landing, it will still fall into the water and be damaged
