Rescue ship marine life rescue device and using method thereof

Abstract

The invention provides a rescue ship marine life rescue device and a using method thereof, wherein the device comprises a lifesaving frame, a door post, a fixing frame, a traction system for conveyingthe lifesaving frame and an overhead cable system for bearing the weight of the lifesaving frame, wherein the overhead cable system comprises an overhead cable winch, a piston tensioner, an anti-loosening device and an overhead cable; the overhead cable extends out of the overhead cable winch, and sequentially passes through the piston tensioner and the anti-loosening device; the overhead cable is connected with the door post and the fixing frame, and bears the weight of the lifesaving frame. According to the rescue ship marine life rescue device and the using method thereof, the constant tension overhead cable technology is innovatively applied to the rescue ship marine life rescue field, so that the rescue ship operation window is effectively expanded, the operation safety is improved,the service and the guarantee are provided for the marine life rescue, and the safe conveyance of rescued people under high sea conditions is achieved.

Description

technical field [0001] The present invention relates to the field of life saving at sea, in particular to a life saving device for a rescue ship at sea and a method for using the same. Background technique [0002] Rescue and salvage is an important part of the national emergency support system, and it is also the backbone of the country's response to major maritime emergencies. With the continuous and rapid development of my country's economy, the number and density of ships, aircraft and personnel at sea continue to increase; from January to November 2018, a total of 1,727 search and rescue operations were organized across the country, and 1,158 Chinese and foreign ships in distress and Chinese and foreign people in distress were successfully rescued. 11,318 people, with a search and rescue success rate of 95.2%. Strengthening research on rescue and salvage equipment technology is fundamental to improving the comprehensive ability of rescue and salvage, and is an important ...

AI Technical Summary

Problems solved by technology

[0003] However, in complex sea conditions, when the rescue ship rescues people from ship to ship, the rescue ship will perform irregular swing motions with 6 degrees of freedom under the interference of external factors such as wind, waves, currents, surges, etc. The working conditions are very complicated and will seriously affect Rescue ships are safe to operate. When offshore helicopters are used for rescue, it is too difficult for rescue helicopters to take off and land on ships in high sea conditions. The swaying and undulating ships make it easy for helicopters to skid and overturn when landing, especially when helicopters are needed for rescue in distress. Often the wind and waves are relatively large, resulting in an increased chance of aircraft crashes and fatalities
