Unmanned ship launching and retrieving device

Abstract

The invention discloses an unmanned ship launching and retrieving device. The device comprises a fixing frame, a guiding mechanism, rotating blocks and limiting blocks; the fixing frame comprises a fixing bracket and two identical lateral fixing parts which are both of a dual-layer structure; the open end of each lateral fixing part is provided with a guiding mechanism of a splay-shaped opening structure; the limiting blocks and the rotating blocks are fixedly to the outer side faces of upper and lower layer frames of the lateral fixing parts; when an unmanned ship is launched, the rotating blocks are rotated downwards, and the unmanned ship is pulled out smoothly; when the unmanned ship is retrieved, the unmanned ship is smoothly moved into the lateral fixing parts under the guidance of the guiding mechanism, the rotating blocks are rotated upwards, the upper and lower layer frames of the lateral fixing parts are connected, meanwhile, limiting is achieved, and the unmanned ship is prevented from rolling out. According to the unmanned ship launching and retrieving device, the unmanned ship can be safely and reliably launched and retrieved automatically under the complex sea environment, the unmanned ship can be prevented from rolling out in the lifting process, and the device has the advantages of being reliable in operation, simple in structure, high in autonomy and the like.

Description

technical field [0001] The invention relates to the technical field of deployment and recovery of unmanned boats, in particular to a device for deployment and recovery of 3-ton (7.5m long) unmanned boats under Class 4 sea conditions. Background technique [0002] Since the beginning of the 21st century, with the substantial improvement of science and technology and military capabilities, the ocean has become a strategic security space that various countries and groups are intensifying to compete for. Pay attention to. Among them, the autonomous deployment and recovery technology is the key to whether the unmanned boat can be launched safely and efficiently and successfully installed. Most of the unmanned surface vehicles currently in use are developed on the basis of manned small boats carried on large ships, and their deployment and recovery use the ready-made davits or ramps on the mothership. This method requires operators to board the unmanned boat and participate in o...

Problems solved by technology

This method requires operators to board the unmanned boat and participate in operations such as attaching the unmanned boat, which is inefficient and dangerous, and this method is only suitable for low speed, low sea conditions, and test voyages
