A detachable floating body device for AUV recovery

Abstract

The invention relates to the field of recycling of autonomous underwater vehicles (short for AUV) and particularly relates to a separable floating body device used for recycling the AUV. The separable floating body device comprises a separable floating force block, a traction rope, an underwater electromagnet, emergency throwing ballast iron and a framework, wherein the separable floating force block is fixedly arranged on an end plate of the framework through an elastic tensioning rope arranged on the separable floating force block; the underwater electromagnet is arranged in the framework and fixedly arranged on a second supporting plate of the framework; the emergency throwing ballast iron is arranged outside the framework and is adsorbed on the underwater electromagnet when the underwater electromagnet is electrified to generate magnetism; a flow guide floating force material is arranged outside the framework; a groove for containing the emergency throwing ballast iron is formed in the flow guide floating force material on the outer side of the second supporting plate of the framework; the framework is internally provided with a rope hub for winding the traction rope; and one end of the traction rope is fixedly arranged on a hub shaft of the rope hub and the other end of the traction rope is connected with the separable floating force block. According to the separable floating body device, people can manually recycle the AUV on a small boat without transferring the small boat to the lower level, and the safety of people and equipment is guaranteed.

Description

technical field [0001] The invention relates to the field of AUV recovery, in particular to a separable floating body device for AUV recovery. Background technique [0002] AUV (autonomous underwater vehicle) is usually equipped with throwable ballast. When an accident occurs or the mission is over, AUV will throw away the ballast to obtain greater positive buoyancy and surface. [0003] In normal work, the AUV needs to be recovered after completing its mission, but due to the influence of wind and waves, it is often very difficult to recover the AUV, which has great risks and is likely to cause injury to personnel and equipment. The most difficult thing in the AUV recovery process is to capture and tow the AUV from the mother ship. In order to ensure the safety of the equipment, the mother ship cannot be too close to the AUV. The traditional approach is to release the dinghy from the mother ship, close to the AUV on the water, and the personnel on the dinghy manually hook ...
