The present invention relates to a pod propulsion device having a submarine rudder function, and in particular, to improve the propulsion device installed in the submarine's stern, the space in which the drive shaft in the enclosure was installed, and other equipment installation and maintenance space. In addition, the present invention relates to a submarine propulsion device that enables an ideal submergence, a change in direction, and an appropriate depth control by improving a safety function from damage of a horizontal rudder.

In general, in the case of a submarine, the rotational motion obtained by supplying power from the electric generator installed in the enclosure to the propulsion motor 3 installed in the ship is transmitted to the external propeller installed at the end of the ship through the propeller drive shaft 4 connected to the motor. And gain momentum.

Ford propulsion system, which is mainly used in some aquatic vessels, has a drive motor and a propeller installed in the pod device installed under the outer hull of the ship, thus eliminating the need for a propeller drive shaft (4) connecting the inside and outside of the ship. Although similar to ships, unlike ships, they have a conical shape and have a living space of about 0.5 pyeong per person, so the double spaces on the second and fourth floors are shared by two to three shifts. Due to the characteristics of the submarine, there is a significant difference in that the space arrangement work can be dramatically improved, and that the submarine performs the function of a horizontal rudder unlike a ship that performs a vertical rudder function in a different installation position.

In the conventional submarine, as shown in FIG. 1, the propulsion motor 3 is connected and installed from the generator 1 and the diesel engine 2 installed in the enclosure 1-1, and the rotary shaft of the propulsion motor 3 is installed. The drive shaft 4 is a structure in which a propeller 5 is connected to the outside while penetrating the stern portion, and is configured to obtain a propulsion force due to the submersion of the submarine.

In addition, the vertical rudder 11 installed vertically on the outside of the enclosure 1-1 and the horizontal rudder 21 on the skeg 20 horizontally installed together with the horizontal rudder 21 may be adjusted to adjust left and right turning and depth. The direction of the submarine's propulsion is set by the horizontal rudder adjusting shaft 6 and the vertical rudder adjusting shaft 7 which are mechanically related to the drive shaft and the vertical rudder adjusting shaft 7 for adjusting the rotation angles of the vertical and horizontal rudders. I'm trying to.

However, the conventional submarine structure as described above has a narrow space inside the longitudinal direction of the ship and, unlike the ship, has a drive shaft, a horizontal rudder adjustment shaft, and a vertical rudder adjustment shaft in the enclosure due to the characteristics of the submarine having a conical shape. Due to the design of the propulsion motor and the position of the propulsion motor, there is a difficulty in arranging the space of the equipment including the internal engine of the submarine.

In other words, the propeller drive shaft and each rudder adjustment shaft are cross-shaped in an extremely narrow space, which results in a congestion of the inside of the stern, and thus, the space inside the stern is urgently needed for maintenance.

As described above, as the submarine's enclosure is enlarged, the design of a generator, a propulsion motor, etc. supporting the submarine is accompanied, which is difficult.

The propeller that is rotated and installed alone outside the enclosure from the drive shaft, for example, there is a problem in that it does not properly function when part of the damage, which may be exposed to extreme danger due to loss of propulsion during accidents due to submerged, single drive shaft As a result, a large amount of propellers need to be installed, which causes a large noise and a large energy loss caused by a long axis.

The present invention has been invented for various problems as described above, to improve the propulsion device installed in the submarine of the submarine to secure the space in which the drive shaft was installed in the enclosure, as well as to improve the function of the horizontal rudder to improve the ideal immersion and improvement The aim is to provide a pod propulsion system with effective depth control.

According to the present invention for achieving the above object, according to the present invention for achieving the above object, the propeller drive shaft through the diesel engine, the generator inside the enclosure is omitted, but the propulsion motor is installed in the pod installed on the outside of the enclosure The propeller is driven and driven through the connected pod propeller drive shaft, and the steering wheel and the depth of rotation of the submarine can be adjusted by adjusting the horizontal rudder adjustment shaft that is operably installed inside the enclosure and the rotary drive shaft that is interlocked with the submarine. In the pod can be rotated up and down with respect to the rotational drive shaft, the rotational drive shaft from the horizontal rudder adjustment shaft to be penetrated horizontally in both sides of the skg installed on the outside of the housing, while driving Propulsion motors are provided at both ends of the rotary drive shaft, and are provided with a propulsion motor. The pod propulsion unit is installed outside the propeller pod is combined with other features for submarine horizontal installed to rotate and adjust the angle by rotating the drive shaft from the opposite ends his schedule is provided.
At this time, the left and right rotation of the pod shaft and the horizontal rudder is rotated by using a pinion gear (not shown) installed at the end of the drive device so that the pod and the pod can be rotated up and down with respect to the rotational drive shaft, so that the swivel and The depth of field can be adjusted.

Hereinafter, the present invention will be described with reference to FIGS. 2 and 3.

2 is a plan view showing the rudder and the propulsion device installed on the naval portion of the present invention submarine, Figure 3 is a side view showing a pod propulsion device according to the present invention.

The present invention includes a vertical rudder (11) and horizontal rudder (21), and the skeg (20), and the like to be interlocked with the generator (1) and the diesel engine (2) side of one side installed in the housing (1-1). In the submarine propulsion device is installed at the same time propeller drive shaft (4) coupled to the propeller 5 for the propulsion according to the forward submersion penetrates to the outside of the enclosure,

Excluding the installation of the propeller drive shaft 4, the pod 50 is pivotally connected to the propulsion motor 3 and the pod propeller drive shaft 8 accommodated therein propulsion propeller (5) housing (1-1) In addition, the pod 50 is installed to be interlocked with the diesel engine 2 side and rotates from both ends of the prop and the propagation force according to the forward submersion of the submarine through the pod 50. It is characterized in that to obtain a vertical rotational force by the drive shaft (10).

The pod 50 is mounted on the lower portion of the skeg 20, which is an outer projecting structure of the enclosure, but is preferably installed in at least one number.

The rotary drive shaft 10 is horizontally penetrated in both sides of the skeg 20 installed at the bottom of the housing 1-1 from the horizontal rudder adjustment shaft 6 to enable the drive, and the rotary drive shaft 10 Both ends of the propulsion motor (3) is provided inside, the pod 50, which is provided with a propeller (5) from the propulsion motor (3) is rotated by the rotary drive shaft (10) from both ends of the skeg (20) It is installed so that angle is adjusted.

Vertical rudder (not shown in the figure) according to the present invention is installed under the same conditions as the vertical rudder of the existing submarine.

For reference, the pod 50 (Pod) refers to a streamlined tank and an enclosure shape, and has only the function of a propulsion device or a vertical rudder, which is already known to be installed in a propulsion device of a large water vessel, and has a vertical rudder and a horizontal rudder. There is no case applied to a submarine that requires all other functions. When installed in a submarine that needs to be moved up and down and left and right, the propeller drive shaft connecting the existing propulsion motor (3) and the propeller (5) outside the propeller ( By omission of 4), unlike the ship, the ship is formed in a conical shape, and the submarine is divided into extremely narrow spaces, and it will provide a significant advantage in securing equipment installation and maintenance space and improving safe operating capability. A drive motor 3 installed in the pod 50 and a propeller 5 for obtaining propulsion force from the drive motor are installed to generate propulsion force according to the navigation of the ship and function as a horizontal rudder through the vertical rotation of the pod 50 itself. Will be performed.

Referring to the operation and effects of the pod propulsion device having a horizontal sub-stroke function for the present inventors configured as described above are as follows.

First, the propulsion of the submarine according to the present invention, as long as the electricity generated through the generator (1) obtained from the diesel engine (2) is connected to it by driving the motor (3) inside the pod (50) installed outside the enclosure. Since propulsion is performed through the pod 50 having the number of dogs or more, the propeller drive shaft 4 connecting the inside and the outside of the enclosure is omitted as compared to the case in which the propulsion motor 3 is installed in a conventional vessel.

This is the propulsion of the enclosure 1-1 by the rotational drive of each propeller 5 installed connected to the pod propeller drive shaft 8 in accordance with the drive of the propulsion motor 3 in the pod 50.

The submarine's turning is performed in a normal vertical rudder (not shown in the drawing), and in addition to the turning motion as described above, the depth adjustment of the enclosure is connected to a horizontal rudder adjusting shaft 6 which can be controlled inside the enclosure. 3) is adjusted as shown in FIG. 3 to obtain the propulsion along with the horizontal rudder angle by adjusting the angle of the pod 50 installed at both ends of the skeg 20 to obtain the depth adjustment of the enclosure 1-1. Can be added.

That is, when the fore part of the pod 50 faces upward based on the skeg 20, the pod 50 is in the submerged direction of the submarine's enclosure 1-1, and vice versa. The propulsion of the propeller 5 in the oriented direction acts as a structure to float the submarine.

The horizontal rudder adjustment shaft 6 can be excluded from the interference with the propeller drive shaft 4 for driving a single propeller in the housing 1-1 because of the condition that it can be installed horizontally. Design is possible.

As described above, the pod 50 propulsion device serving as a rudder of the submarine according to the present invention is configured to obtain propulsion while having a horizontal rudder function in the submarine of the submarine, and is installed in both directions of the skeg 20. Therefore, even if a failure of propeller 5 and propulsion motor 3 occurs on one pod 50 side, one or more plural pods 50 are provided with propulsion force, so the advantage that can be dealt with in a dramatic risk situation have.

In addition, it is possible to delete the propeller drive shaft (4) that was installed to drive the independent propeller of the submarine by each of the independent installation operation of the propulsion motors respectively installed on the propulsion device side of the pod 50 to rotate the propeller. .

Accordingly, it is advantageous to secure the space inside the enclosure 1-1, ie, the side of the ship, which is useful for various maintenance and layout design of the engine.

In addition, the propeller 5 applied to each of the pods 50 can be reduced to half the size of the existing propeller alone, thereby reducing the propulsion noise due to the submersion.

In addition, by setting the pod 50 in the lower portion of the skeg 20, which is an outer projecting structure of the enclosure instead of the bottom, by setting the propulsion force of the propulsion motor (3) provided in each pod to maximize the maximum direction change with the seam It can help you to have the advantage of double the combat ability.

As described above, in the present invention, in the submarine, the pod propulsion unit having a horizontal stroke function may be installed at both ends of the skeg installed at the stern to rotate them up and down, thereby omitting the propeller drive shaft connecting the inside and outside of the enclosure. Unlike the conventional vessels, the vessel is formed in a conical shape unlike the ship, and due to the nature of the submarine, an extremely narrow space is allocated, it is easy to secure equipment installation and maintenance space, and it is possible to quickly change the direction and adjust the depth, and symmetrical pods. By deploying in pairs, a redundancy function can be established that can operate even if one of the devices is damaged.
