High-capacity variable-attitude cable-free deep-submersible lifeboat

Abstract

The invention provides a high-volume sailing-posture-changeable and non-cable type deep diving lifeboat. The purpose of the invention is to design a novel non-cable type deep diving lifeboat with high carrying capacity and strong flexibility in the change of sailing posture. The deep diving lifeboat comprises a clipper-built hull composed of a half-ball inflow segment, a cylindrical-parallel middle body and a circular cone type outflow segment. The stern of the clipper-built hull is provided with a main thruster; the bow of the clipper-built hull is provided with a bow hatch cover; the front segment and the back segment both of the cylindrical-parallel middle body are each provided with a pair of auxiliary thrusters, which are in left-right symmetry; the middle segment of the cylindrical-parallel middle body and the circular cone type outflow segment are each provided with a pair of horizontal tails, which are a pair of vertical tails of different sizes are symmetrically arranged on the circular cone type outflow segment in the up-down direction; the lower portion of the middle segment of the cylindrical-parallel middle body is provided with a revolving-skirt interface. The deep diving lifeboat has the advantages of being high in carrying capacity, strong in flexibility in the change of sailing posture, high in the efficiency of rescue and the like.

Description

technical field [0001] The invention relates to a lifeboat, in particular to a cableless deep-submersion lifeboat with high capacity and variable attitude. Background technique [0002] Since its birth, submarines have been playing the role of ship killers and are one of the most important weapons in modern naval warfare. However, during the service of submarines, accidents and sinking accidents occur from time to time, and each accident is a tragedy. The nature and reasons of submarine accidents are various, and accidents caused by fire, explosion, collision, flooding, grounding, storm and even nuclear accidents occur frequently. [0003] The Deep Submersible Rescue Boat (DSRV) is a manually operated diving device that can maneuver underwater. It can rescue the crew members of the wrecked submarine at a large depth and under normal pressure. It has good performance in rescue and rescue. Therefore, it is considered to be the main means of submarine lifesaving and security,...

AI Technical Summary

Problems solved by technology

Although the angle of inclination is large, there are still restrictions, and the flexibility of changing posture is poor

When the wrecked submarine tilts at an angle greater than 45°, it will be difficult to successfully dock, resulting in the failure of rescue operations

At the same time, the limitation of the inclination angle is not conducive to the adjustment of the lifeboat to the sailing attitude with the least resistance, which increases energy consumption to a certain extent.

When using the American DSRV, it needs the support of a dedicated working mother ship or mother ship. The workload and expense of daily maintenance are very large, and it is impossible to respond quickly when the submarine crashes. The rescue efficiency is low, wasting precious rescue time and reducing the survival of the crew. probability
