Anti-skid locking mechanism for unmanned aerial vehicle(UAV) landing on unmanned surface vehicle (USV)

Abstract

The invention relates to an anti-skid locking mechanism for an unmanned aerial vehicle(UAV) landing on an unmanned surface vehicle (USV), which is used for enabling the UAV to stably land and take offon the USV at sea. The invention is characterized in that the anti-skid locking mechanism comprises a pressure sensor arranged in a landing area on the surface of the circular landing platform of a search boat, an UAV controller communicated with the pressure sensor and two locking rods respectively arranged at the two side edges of the circular landing platform of the search boat in a face to face manner; one end of each locking rod is fixed at the edge of the landing platform of the search boat through a rotating shaft; and the UAV controller controls the rotating shafts to rotate through adriving motor for realizing the open and the close of the locking rods. Compared with the prior art, the invention has the advantages of automatic locking, convenient operation, and the like.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an anti-skid locking mechanism for unmanned aerial vehicles to land unmanned boats. Background technique [0002] There are many kinds of sudden disasters at sea, many of which will endanger the personal safety of rescuers and bring great challenges to maritime search and rescue. Unmanned systems (unmanned boats or unmanned aerial vehicles) have great advantages in such search and rescue where there is a risk of casualties or where it is not possible to dispatch manned ships. Simultaneously carrying out flexible three-dimensional search and rescue at sea is a powerful means for future maritime search and rescue. [0003] The unmanned boat is characterized by strong endurance and large load, and can carry a variety of sea and underwater search and rescue equipment. However, due to the limited height of the hull, its observation range, communication distance and ability to receive radio s...

AI Technical Summary

Problems solved by technology

However, due to the limited height of the hull, its observation range, communication distance and ability to receive radio signals will be greatly limited by water surface reflection and wave occlusion; UAVs are characterized by large observation range, long communication distance, and ability to receive radio signals. Strong, but the load is small and the endurance is very limited

If the two are combined for formation coordination, the unmanned boat with strong endurance and load capacity will carry the unmanned aerial vehicle to the designated work area, and the unmanned aerial vehicle with limited endurance will take off to perform the task of search, reconnaissance or communication relay. After returning to the voyage by boat after the mission, the strengths of the two can be used to realize search and rescue in a large area, all-weather, in high sea conditions, and without the risk of casualties. and other disturbances in the marine environment, inevitably resulting in sway

Swaying will bring great difficulties to the landing of the drone. When the drone lands, it may slide into the sea due to the shaking of the drone, or it may not be able to take off normally again.
