Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an underwater UAV deployment and retrieval device and method based on a rotary scissor mechanism. Background Technology

[0002] Underwater unmanned vehicles (UAVs) are important equipment for countries to explore and develop the ocean. Because UAVs need to operate in the marine environment for extended periods, high demands are placed on their operational capabilities and endurance. Therefore, the deployment and recovery of UAVs are extremely critical aspects.

[0003] Currently, underwater unmanned vehicles (UAVs) are primarily deployed and recovered using manned surface mother ships. During deployment, the UAV is lowered into the water using a hoisting device on the mother ship. For recovery, there are two methods: one is for the UAV to surface first and then be retrieved by the mother ship; the other is for the UAV to first dock with the docking device used for lowering into the water, and then be hoisted onto the mother ship's deck. After the UAV has completed data transmission and replenished its energy, the mother ship then performs the deployment.

[0004] The deployment and recovery of unmanned underwater vehicles using manned surface mother ships presents the following main problems:

[0005] (i) High cost, requiring the mother ship to be equipped with special lifting and launching equipment, as well as a large number of professional and technical personnel;

[0006] (ii) It is greatly affected by the environment. When the sea conditions are large, the deployment and recovery operations are difficult and there is a risk of collision between the underwater vehicle and the mother ship.
