multifunctional buoyancy chamber

Abstract

A multifunctional buoyancy cabin comprises a buoyancy cabin box, a connecting component and a connecting thread. The buoyancy cabin box is a movable watertight box with a compartment, more than two grooves are formed in the upper portion of one side of the buoyancy cabin box along the side face of the buoyancy cabin box, a T-shaped anti-collision pendant of the connecting component is fixed on a hull while angle components, pin shafts and positioning locking pins of the same are mounted in the grooves of the buoyancy cabin box, the angle components are matched with the T-shaped anti-collision pendant, and the connecting thread serves as a connecting member between the lower portion of the buoyancy cabin box and the hull. The multifunctional buoyancy cabin has the advantages that connecting or demounting between the buoyancy cabin and the hull connecting component is convenient and quick; the multifunctional buoyancy cabin is used for temporarily increasing buoyancy, increasing load bearing capacity, increasing ballast water carrying capacity, improving stability and safely diving and floating under special loading circumstance; during marine maintenance operation, the buoyancy cabin is mounted along the side of a deck, so that dock wall effect is realized; the buoyancy cabin can be used as a float to be matched to salve sunken ships and sunken objects; the buoyancy cabin can be loaded with freshwater, fuel, supplies, materials and maintenance materials for open sea supply and maintenance support.

Description

technical field [0001] The invention belongs to the field of ships and marine engineering, and in particular relates to a semi-submersible transport ship, a semi-submersible maintenance ship and a semi-submersible ocean platform. Background technique [0002] In the prior art, semi-submersible ships are mainly used to transport large-scale equipment, and have the characteristics of large scale, strong carrying capacity, and the ability to dive and float. The shortcomings of the existing technology are: first, the carrying capacity, lifting force and deck area of ​​the semi-submersible ship are determined by the design, and cannot be increased during use, which constitutes a limitation for the transportation of some overweight and oversized pieces; second, if the ship carries maintenance, salvage If there is a lot of equipment, it will occupy the space of the cabin or the capacity of the ballast tank, which will reduce the load capacity of the ship and the capacity of the bal...

Problems solved by technology

The shortcomings of the existing technology are: first, the carrying capacity, lifting force and deck area of ​​the semi-submersible ship are determined by the design, and cannot be increased during use, which constitutes a limitation for the transportation of some overweight and oversized pieces; second, if the ship carries maintenance, salvage If there is a lot of equipment, it will occupy the space of the cabin or the capacity of the ballast tank, which will reduce the load capacity of the ship and the capacity of the ballast tank will be tight, which will affect the safety of the ship's diving and floating operations; the third is that the semi-submersible ship has few functions and its potential role cannot be fully utilized.
