Abrégé

The present invention relates to a diver propeller wherein the same has a stern portion configured to be able to switch between a folded state and an unfolded state such that space necessary for storage can be reduced; the diver propeller basically has negative buoyancy and is configured such that a buoyancy adjusting bag can be additionally connected thereto and used; accordingly, neutral buoyancy can be adjusted appropriately in response to a change in specific gravity of seawater, fresh water, or the like or in response to a change in weight resulting from modification of mounted equipment; and, consequently, buoyancy can be adjusted easily according to various underwater situations or task situations. To this end, the diver propeller according to the present invention comprises: a stem portion having a semispherical or streamlined shape; a hull portion which is connected to the rear end of the stem portion, the upper portion of which is open, and which has a semi-cylindrical shape; and a stern portion capable of switching between a folded state in which the same is positioned inside the hull portion and an unfolded state in which the same is positioned to extend from the rear end of the hull portion, wherein the diver propeller is configured to have negative buoyancy.

The present invention relates to a dry/wet hybrid submersible enabling an entire crew compartment of the submersible to be utilized as one pressure chamber having multiple functions such as a crew compartment function, a lockout chamber function, and a ballast tank function, and enabling the time, required for a crew to enter and exit when the submersible submerges, to be remarkably reduced. To this end, the dry/wet hybrid submersible of the present invention comprises: a hull part having the crew compartment for the boarding of the crew and the installation of waterproof equipment; a hatch part opening or closing the crew compartment, communicating with the crew compartment so as to enable the crew to enter and exit when the hatch part is opened, and provided at the lower part of the hull part; and a valve part allowing seawater to flow into the crew compartment or seawater in the crew compartment to be discharged to the outside.

The present invention relates to a submersible ship waterproof housing and a submersible ship having the same, and can provide the submersible ship waterproof housing through a simple process of providing a casing after mounting a water propulsion part on the inner bottom of the submersible ship, prevents the location of the ship from being easily exposed by heat detection since high-temperature exhaust gas is discharged in the water and cooled, and can reinforce a hull since transoms, which form the bottom and stern of the hull, are connected and fixed to each other by a lower casing. To this end, the submersible ship waterproof housing of the present invention comprises: the casing of which at least the lower part is formed to be opened such that the water propulsion part mounted on the inner bottom of the submersible ship is sealed in accordance to the sealing and assembling of the casing at the inner bottom of the submersible ship; an intake port operated to be opened and closed such that air can flow into the casing; and an exhaust port operated to be opened and closed such that the exhaust gas can be discharged to the outside of the casing.

The present invention relates to a single acting type vessel provided with a fluid flow portion for reducing ship waves, capable of reducing ship waves produced on the water surface by forming the fluid flow portion on a draft line on the vessel so that ship waves on the water surface are guided through the fluid flow portion to the center part of the rear surface of a hull body. To this end, the single acting-type vessel provided with the fluid flow portion for reducing ship waves, according to the present invention, comprises the fluid flow portion defined by a groove on the draft line connecting side surfaces and the rear surface of the hull body, wherein ship waves on the water surface flowing along the side surfaces of the hull body are guided to the center part of the rear surface of the hull body.
