Submersible and method of controlling the same

摘要

A submersible designed so that a cabin for boarding an operator has a size just enough to accommodate the operator and even such a light weight of the submersible can cause the submersible to submerge. Furthermore, when an operator having a weight smaller than a design maximum operator's weight of the submersible is on board, and therefore the total weight of the submersible is reduced and the buoyancy thereof is increased, the buoyancy of the submersible is adjusted by pouring water having a weight corresponding to a difference between the design maximum operator's weight and the actual weight of the operator into an expansion container, disposed in the cabin, capable of expanding by containing water. In this manner, the net weight of the submersible is prevented from increasing.

主权项

1. A submersible comprising:
a cabin for boarding an operator; a first tank constituting a body of the submersible and configured to lower buoyancy by inflow of water at the time of submergence; a second tank disposed inside the first tank; a first water supply and discharge pipe configured to allow water movement between an outside of the first tank and the second tank; a first air supply pipe configured to allow air movement between an air supply unit for supplying air and the second tank; a third tank disposed inside the first tank; a second water supply and discharge pipe configured to allow water movement between the outside of the first tank and the third tank; a second air supply pipe configured to allow air movement between the air supply unit for supplying air and the third tank; a fourth tank disposed inside the first tank and having an ascent tank and a descent tank; a third water supply and discharge pipe configured to allow water movement between the outside of the first tank and the ascent tank; a third air supply pipe configured to allow air movement between the air supply unit and the ascent tank; a fourth water supply and discharge pipe configured to allow water movement between the outside of the first tank and the descent tank; and a fourth air supply pipe configured to allow air movement between the air supply unit and the descent tank.
