Watercraft recovery device

Abstract

The invention relates to the technical field of unmanned watercraft and manned watercraft recovery, in particular to a watercraft recovery device. The watercraft recovery device comprises a net bag and an inflatable or deflatable air bag mounted along the edge of the net bag, wherein the air bag forms a floating body after being inflated; the floating body comprises a bulwark connected to the edgeof the net bag and a support frame erected on the bulwark; the support frame, the bulwark and the net bag form a holding space for holding watercraft and a tail opening for the watercraft to enter into and exit from the holding space; and the head end, opposite to the tail opening, of the floating body is connected with a main cable. When the watercraft can not be directly recovered by a mother ship under a terrible sea condition, the watercraft can be held and recovered by the watercraft recovery device and towed by the mother ship, so that the watercraft can be in a controlled state under the terrible sea condition. The watercraft can be recovered to the mother ship when the sea condition is improved, or the watercraft recovery device can be towed to the side of the mother ship as needed. The watercraft recovery device is convenient for staff on the mother ship to rescue people on the watercraft, thereby realizing the effective and step-by-step recovery of the watercraft under the terrible sea condition and ensuring the safety of watercraft recovery.

Description

technical field [0001] The invention relates to the technical field of recovery of unmanned boats and manned boats, in particular to a boat recovery device. Background technique [0002] An unmanned surface vessel is an unmanned surface vessel, mainly used to perform dangerous and unsuitable tasks for manned vessels. Once equipped with advanced control systems, sensor systems, and communication systems, it can perform maritime rescue, surveying and mapping, etc. Task. [0003] For example, in view of the current golden period of post-disaster rescue, the difficulty of rescuers arriving at the scene due to the harsh sea environment, and the urgent need for life rescue time, China has used the existing technical foundation to develop unmanned sea rescue equipment and related configurations. The practical research of the instrument focuses on breakthroughs in key practical technologies such as autonomous control of anti-wind and wave, rapid target positioning and drift predict...

Problems solved by technology

[0004] However, these unmanned boats can usually only be recovered by the mother ship crane when the sea conditions are good. In high sea conditions, due to the influence of wind, waves and currents, it is difficult for the unmanned boats to approach the mother ship, or even if they are close to the mother ship, they cannot be effectively hooked, and Very easy to collide with the mother ship

[0005] In addition, considering the safety and effectiveness of recovery, the manned boats equipped on the mother ship must choose better sea conditions when they need to perform tasks, and their use is limited.
