Abstract
This invention is type of dual-purpose boat, including cabin and hull. This boat is unique in that between the cabin and hull there is a lifting mechanism connecting the hull and cabin, at least one of which has been set up with a buoyancy regulating structure. This invention can be used as a regular boat, or if the cabin is lowered, this invention becomes a semi-submerged vessel that can be used for operational purposes or underwater sightseeing. When the invention enters shallow water or needs to navigate at high speed, the cabin can be raised to prevent beaching and to reduce resistance. The operation of this invention is simple and expands the single function of current boats.
Claims21
A dual-purpose boat, comprising a hull and a cabin, wherein the cabin and the hull are connected to each other by a lifting mechanism, at least the hull contains a buoyancy regulating structure, and the buoyancy regulating structure includes space to hold water or air and includes an inlet valve for water inflow into the space and pump or a drain valve for water discharge, wherein water flows into the space in the hull as the cabin descends.
A dual-purpose boat, comprising a hull and a cabin, wherein the cabin and the hull are connected to each other by a lifting mechanism configured to variably position a top portion of the cabin above the hull and a bottom portion of the cabin below the hull, wherein the hull or the cabin, or both, contains a buoyancy regulating structure, and wherein a stopper structure is placed between the hull and the cabin to limit a horizontal displacement of the cabin relative to the hull, the stopper structure having a guide post and a guide sleeve that are mutually matched.
A dual-purpose boat, comprising a hull and a cabin, wherein the cabin and the hull are connected to each other by a lifting mechanism configured to variably position a top portion of the cabin above the hull and a bottom portion of the cabin below the hull, wherein the hull or the cabin, or both, contains a buoyancy regulating structure, and wherein the lifting mechanism functions via one or more winding engines, worm gears, or rack-and-pinion mechanisms.
A dual-purpose boat, comprising a hull and a cabin, wherein the cabin and the hull are connected to each other by a lifting mechanism configured to variably position a top portion of the cabin above the hull and a bottom portion of the cabin below the hull, wherein the hull or the cabin, or both, contains a buoyancy regulating structure, and wherein the hull has a sensor that detects a vertical position of the boat relative to a surface of water and controls buoyancy of the boat.
A vessel comprising:
- a hull defining a displacement and being floatable on a body of water;
- a cabin slidably mounted to the hull;
- and
- a cable actuation system extending between the hull and a top portion of the cabin, the cable actuation system configured to selectively draw the cabin from a raised position downwardly toward the hull to a lowered position and allow the cabin to rise from the lowered position to the raised position, the cable actuation system mounted to the hull and cabin such that no portion of the cable actuation system is located above the cabin when the cabin is in the raised position.
