Problems solved by technology

At the same time, a large amount of financial and material resources and human resources have been invested in marine engineering equipment, which costs a lot and leads to an increase in costs.
Relevant departments will be limited by the tonnage of the sunken ship, the sea conditions and other conditions when salvaging the sunken ship at sea, which hinders the salvage work. In addition, renting or purchasing large-scale equipment during the construction of offshore projects will greatly increase the economic pressure of the enterprise

Embodiment

[0056] Example: as attached figure 1 Shown is a schematic diagram of the tidal current energy estimation module. After determining the location of the salvaged wreck 2, measure the current information of the water area according to the conditions of the salvage and haulage operation water area, including the current flow direction and velocity in the whole area at all times. as attached figure 1 Among them, the equipment selection is currently more commonly used ADCP, adopting the fixed-point measurement method, and deploying four pieces (1a, 1b, 1c, 1d) of the equipment around the sunken ship in the salvage operation water area of ​​the sunken ship 2, which can combine the tidal properties of the water area and The cycle determines the observation time, generally 48h. By analyzing the data collected by the equipment, we can get the tidal current change law of the water area with time as the independent variable, and get the flow velocity V of the water area t and flow to D...

Abstract

The invention discloses a sunken ship salvage and haulage system based on tidal current force. Using tidal currents acting on the operating waters, using airbag floating tanks to salvage and haul sunken ships, the system can be used in underwater heavy haulage and in operations such as the handling of engineering caissons or offshore structures. The invention utilizes an air bag floating box to assist in salvage. It is easy to control the buoyancy by reasonable fastening and binding of the buoyancy tank, and the buoyancy of the buoyancy tank under uniform force can reduce the bending stress caused by the traditional salvage method on the sunken ship, at the same time, the auxiliary force for the surface operation crane can be generated, and the dependence on the heavy crane during the salvage process of the sunken ship can be reduced.

Description

technical field [0001] The invention relates to the field of sunken ship salvage and haulage, in particular to a sunken ship salvage and haulage system based on tidal force. Background technique [0002] With the implementation of the national ocean power plan, the development of my country's engineering technology has gradually shifted from land to sea, and there are more and more problems to be solved in the haulage of large and heavy objects at sea, especially involving underwater salvage and haulage of sunken ships, Transportation of large marine structures, etc. In recent years, my country's marine engineering construction has made remarkable achievements in the R&D and manufacturing of large-scale machinery and equipment. The salvage bureaus have gradually increased the R&D efforts to make the lifting tonnage of heavy equipment gradually reach 3000t-4000t, and even Shanghai Zhenhua Heavy Industry broke through in 2010. The key technology of 8 000t floating crane constru...
