JP2015131562A - High depth buoyant tube - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a buoyant tube that is designed as means for enabling a heavy load to come and go by using buoyancy in a distance between a seabed and a sea surface as means for recovering resources in the deep sea, and occasionally is usable for relief every ship.SOLUTION: A buoyant tube is characterized as follows: an air pressure when arriving at the bottom of the sea is input when submerged, and neutral buoyancy is obtained by the volume of the buoyant tube; a construction machine being a heavy load, made in future and automatically drive in the seabed is hung and submerged, is made to descend slowly while filling an air pressure becoming insufficient according to the water depth, and is carried without destroying the machine being a load to the seabed of the deep sea; wire is hung and changed to a basket loaded with the slag of rare metal recovered at the seabed, and the basket is fed with the air necessary for obtaining buoyancy and is moved up; the expanding air in the buoyant tube according to the decrease in hydraulic pressure is discharged outside when moved up; ballast tanks are placed at both sides on the buoyant tube so that the buoyant tube may not be inclined due to air pressure fluctuating in the tube; and the buoyant tube is moved up while applying tension thereof by using a small amount of weight and buoyancy of the ballast tanks.

Description

The present invention provides a technique as a means for transporting minerals or earth and sand containing rare metals from the deep sea floor to the interface from the sea floor.

Recently, methane hydrates and rare metals have been discovered in Japan's economic waters, and the depth of the water is over 100m and it is on the seabed of thousands of meters. I think that it can be sucked up with vacuum if it is a thing, but it can not be sucked up with rocks etc., so a construction machine that moves automatically for the deep sea floor must be developed, but the construction machine is developed and deep sea If the rocks are crushed and collected, it will naturally require a means of transport from the sea floor to the sea level. So, if you put sea water in a cylindrical tube and sink it to the sea floor like a concealed device, there is sea water in the cylinder and it will not be crushed by water pressure, If the compressed air is replenished while sinking the floating cylinder with the cavity, the relationship between the water pressure and the air pressure is 10 m and the pressure is 1 atm. Since it descends slowly, the relationship between water pressure and air pressure is 1: 1, and the water pressure and water depth is 1:10. From the beginning, the air that matches the water pressure at the bottom of the sea is sent little by little into the floating cylinder. If it does, it will sink slowly while the air is shrunk to the water pressure while removing the seawater with the capacity in the floating cylinder. Ultimately, air is sent with compressed air pressure against the water pressure at the bottom of the sea, so it is possible to carry heavy objects to the sea floor without crushing the air supply pipe. An object of the present invention is to provide a floating cylinder that does not rupture while releasing reduced water pressure and air expanding in the floating cylinder into seawater.

The vacuum hose is thick to pull up minerals, and if it is several hundred meters to several thousand meters, it will be a huge facility to carry and set up the ship with only the hose, waiting for the development of construction equipment for deep sea However, if the levitation cylinder is a compressed air hose, it is thinner than the vacuum hose. The cylinder becomes heavy and less likely to be swept away. By introducing seawater or compressed air into the floating cylinder, it reaches the sea floor without being crushed by the water pressure, and the air pressure corresponding to the water pressure is sent from the ship so that it sinks. It will not be crushed, but will rise while escaping air when rising, so it will rise without rupture.
