Sunken vessel salvaging method and device

Abstract

The invention discloses a sunken vessel salvaging method and device. The sunken vessel salvaging device comprises a load bearing framework and salvaging airbags, wherein the load bearing framework is provided with a sunken vessel fixing device; the sunken vessel fixing device on the load bearing framework is connected with a to-be-salvaged sunken vessel; the salvaging airbags are arranged on the outer side and the inner side of the to-be-salvaged sunken vessel, so that the sunken vessel is fixed in the framework; the to-be-salvaged sunken vessel and the overall load bearing framework are driven to run to the shore side underwater by a working towing vessel and a travelling device on the load bearing framework; and the to-be-salvaged sunken vessel is dragged to the shore by a dragging device when the to-be-salvaged sunken vessel arrives at the shore side. By virtue of the sunken vessel salvaging method and device, the salvage of the sunken vessel is not limited by the weather of the sea surface; the salvage of the sunken vessel is relatively safe and reliable; the possibility that the sunken vessel and the goods in the vessel are damaged by the stormy waves on the sea surface is avoided, so that the salvaged sunken vessel and the goods in the vessel can be well preserved; and in addition, tools used in the whole salvage process are relatively simple and convenient to implement.

Description

technical field [0001] The invention mainly relates to the technical field of underwater salvage machinery, in particular to a sunken ship salvage method and device. Background technique [0002] Affected by weather and other reasons, when ships sail in rivers, lakes and seas, shipwreck accidents will inevitably occur on the water. In order to understand the cause of the shipwreck, or to dredge the water channel, or to recover the loss of the shipwreck, people are always trying to use various methods To salvage the sunken ship, there are two main methods for salvaging the sunken ship: one is to use mechanical power to lift the sunken ship out of the water surface to complete the salvage; the other is to use the buoyancy to salvage the ship. The key technology is to restore the buoyancy of the sunken ship and then re-surface the water to facilitate salvage. At present, this method is often used in the field of sunken ship salvage. Drainage and salvage, etc. And salvage ship...

AI Technical Summary

Problems solved by technology

And salvage shipwreck generally all is in slightly distant sea area, and the device that above-mentioned method adopts all needs to finish salvage action on sea surface, must select to carry out in the weather with little wind and wave, but this weather is rare in ocean, and there are also It lasts for a short period of time, which means that the work of salvaging sunken ships must be completed in a short period of time, otherwise the consequences will be disastrous. This is also an important reason why many salvageable sunken ships are still sleeping in the deep sea.
