That is, a ship that provides convenience that can be operated both in the water and in the water is presented. When the stern gate is closed and the stern is transformed into a bow shape of a submarine and descends into the water in the state of streamline, the ballast system balances forward, backward, left and right, and at the same time, the underwater propeller before and after the ship protrudes. Each submerged propeller has the advantage of being able to adjust the angle of inclination as well as being drawn into and out of the hull as necessary, and to be able to operate the ship during the week, by controlling the injury, drowning and depth of the hull.

The stern gate, which was opened at the time of the water voyage, is closed and closed, and the ship maintains its streamlined form. At the time of underwater voyage, the stern portion plays the role of a player and voyages in the opposite direction to the water voyage. The streamlined shape exhibits the hydrodynamic characteristics of minimizing the resistance, thereby reducing the energy consumption of the underwater propulsion power source.

Fig. 1 is a perspective view of a first underwater propeller and an internal structure for operating the first underwater propeller, Fig. 4 is a perspective view of a second underwater propeller and an internal structure for operating the same, and Fig. FIG. 5 is a combined perspective view of a third underwater propeller and an internal structure for operating the third underwater propeller. FIG.

Figure 3 is a port side submerged propeller. The meaning of the port means the underwater propeller on the left when viewed from behind the hull.

As can be understood from Figs. 1 and 2, the shape of the vessel of the present invention is formed so as to enable water navigation and underwater navigation.

2, the aft gate has the same appearance as a general ship at the time of a water voyage (FIG. 2). The stern gate 500 is opened and the stern gate is drawn into the inside of the hull. And the water jet nozzle 600 is formed at the stern portion, so that the water voyage can be carried out using the water jet nozzle 600.

An air intake gate 100 is formed in the upper part of the deck for smooth air supply to the engine.

However, in the case of underwater navigation, the hull moves in the direction opposite to the direction of the water navigation as shown by the arrow in Fig.

As shown in FIG. 1, the stern gate 500 is closed so that the stern portion is curved, and the first to third underwater propellers 11a, 11b, and 11c are projected to the outside of the hull, .

As will be described later, the three submerged propellers are formed with screws, so that it is possible to generate hull propulsion power, and it is also possible to steer left and right or up and down, .

The third underwater propeller 11c is capable of steering right and left, and may serve as a rudder of a vertical rudder of a submarine or a general ship that sails.

In order to perform underwater navigation, the sliding doors 300 and 301 must be opened first. After the sliding door is opened, the first and second underwater propellers (11a, 11b) and the third underwater propeller (11c), which are respectively drawn on the side of the ship and under the deck of the bow, are drawn out by the hydraulic cylinder.

The first and second submerged propellers unfold and protrude in a direction parallel to the water surface, and the third underwater propeller protrudes in a direction orthogonal to the water surface.

When all the underwater propellers are protruded and fixed by the clamps, the sliding doors are closed again. Since the core elements of the present application are the underwater propeller and the devices for driving the same, the other components are well known technologies and detailed description thereof will be omitted.

As shown in FIG. 3, the two submerged propellers on the side of the hull can rotate in the k-direction or vice versa and control the depth of the hull in the water. Preferably, the angle of k is such that it can be rotated at an angle of -30 to 30 degrees relative to the surface of the water, and is not necessarily limited thereto.

The structure and function of each submerged propeller for driving the hull of the present invention will be described below.

FIG. 3 shows an assembled perspective view of the internal structure for operating the first underwater propeller 11a. 4 is a perspective view of an internal structure for operating the second underwater propeller 11b, in which the underwater propeller is unfolded unlike FIG.

3 and FIG. 4 will be described simultaneously. Since the first and second underwater propellers 11a and 11b are protruded from the hull, the first and second underwater propellers are driven by the first motor 1 positioned at the center So that it is symmetrical. 3 is a sectional view taken along line B of FIG. 4, and FIG. 3 and FIG. 4 are separately shown for the sake of convenience.

The driving force generated from the motor is transmitted in the reduction gear box and then delivered to the screw by a power transmission means such as a universal joint and a predetermined shaft in the underwater propeller control pipe.

FIG. 3 shows a state in which the underwater propeller 11a is deployed for underwater navigation (FIG. 1). FIG. 4 shows a situation in which the underwater propeller 11b is folded into the hull It is showing.

The water hammer control pipe supports 6a and 6b, the universal joint boxes 7a and 7b, the clamp supports 10a, 10b, 10c and 10d and the clamps and the underwater The propellers 11a and 11b are positioned one after the other.

The operation of the underwater propeller is preferably configured to rotate from 0 degrees to 80 degrees around the universal joint boxes 7a, 7b. The underwater propeller is equipped with a screw, which generates the propulsion power of the hull, and protrudes outside the hull only when underwater.

The submersible propeller 11a body is coupled to an underwater propeller control pipe 12 and an underwater propeller operating cylinder 5a is coupled to one end of the underwater propeller control pipe 12 so that an underwater propeller control pipe 12 ) To allow the underwater propeller to be located at the position of Fig. 3 or Fig.

In the case of FIG. 4, similarly, the underwater propeller operation cylinder 5b, which is coupled to one end of the underwater propeller control pipe 12a, functions to position the underwater propeller 11b inside or outside the hull.

As shown in FIG. 4, when the underwater propeller 11b is in the hull for water navigation, the clamp 21 must be released and the underwater propulsion control pipe 12a must be detached from the clamp. It is preferable to release the clamp by the oil pressure of the clamp opening / closing cylinders 8c and 8d.

In FIG. 3, the underwater propeller control pipe 12 is unfolded by the operation of the clamp opening / closing cylinders 8a and 8b and is constrained to the clamp.

Hereinafter, the process and related components of steering the water propeller 11a in the k-direction or in the opposite direction, with the underwater propeller 11a unfolded in water as in the state of Fig. 3 will be described.

In this case, by rotating the submersible propeller 11a in the direction k or vice versa, it is possible to perform such hull operation. do.

For example, when the underwater propeller 11a descends in the k-direction as shown in FIG. 3, the hull shown in FIG. 1 proceeds in a direction to incline in water.

In this operation, when the up-down steering cylinder 3 formed on the upper side of the reduction gear box 2 is pulled in the W direction, the underwater propeller upper and lower controller 4 connected to the up-down steering cylinder is rotated and the underwater propeller control pipe 12 And the underwater propeller 11a rotate in the direction k.

Of course, in order to operate in the direction opposite to k, it is possible to operate the up-and-down steering cylinder 3 in the direction opposite to W.

When the up-and-down steering cylinder 3 is operated, the submerged propellers 11a and 11b arranged symmetrically with respect to the hull are simultaneously rotated in the direction opposite to the k direction or k, .

The configuration and function of the third underwater propeller formed on the forward side of the hull will be described with reference to FIG.

The function of the third underwater propeller 11c is similar to that of the first and second underwater propellers 11a and 11b, generating a propulsive force of the hull. However, unlike the first and second underwater propellers, when the hull is underwater, it can act as a kind of rudder that can be operated while adjusting the lateral direction.

Referring to FIG. 5, the power for rotating the screw of the third underwater propeller 11c is generated by the second motor 1a, and the power is transmitted to the screw through the predetermined gear and shaft device. The same as in the case of the first and second underwater propellers described.

The water hammer control pipe support 30, the universal joint box 50, the clamp support 10e and the clamp 21c and the water propeller 11c are formed in order from the second motor 1a. Is the same as in the case of the first and second underwater propellers (Figs. 3 and 4). Only one clamp is shown in Fig. 5, but two or more clamps can be formed.

However, this third underwater propeller is standing vertically and can be pulled into the inside of the hull by moving forward in the hull and moving out of the hull by moving in the opposite direction.

The intake and withdrawal of the third underwater propeller 11c is effected by the driving force of the underwater propeller operating cylinder 5c coupled to one side of the stop of the underwater propeller control pipe 12b as in the case of the first and second underwater propellers described above Do. That is, when the cylinder 5c is operated to advance to the right in Fig. 5, the third underwater propeller 11c is drawn into the hull.

The operation in which the third underwater propeller is switched in the y1 and y2 directions is such that the operation of the underwater propeller left and right steering cylinders 80 is transmitted to the predetermined link connected by the key and the cylinder key 82,81, It is possible to rotate the control pipe 12b.

The rotation to y1, y2 corresponds to acting as a rudder to divert the hull to the left and right.

That is, in FIG. 1, the third underwater propeller (11c) is positioned at the rear end of the traveling direction and takes charge of direction control for turning the propulsion of the hull in the left and right direction.
