Description

  The present invention relates to a submersible craft, and is particularly suitable for a submersible or submarine with a rudder normally arranged in an X shape (including these submersibles).

  A normal surface ship that sails in the state of floating on the water enables free navigation on the water by the equipped vertical rudder. On the other hand, there are also known submersible boats that can be submerged in water for marine research purposes and military purposes. It is set to sink by making it larger than buoyancy.

  When the submersible sails underwater, the submersible needs to change not only the navigation direction in the horizontal direction but also the navigation direction in the vertical direction, unlike the surface ship. In other words, since it is necessary to perform three-dimensional solid motion in water, it is possible to perform horizontal balance and sub rudder in addition to vertical rudder in addition to changing the direction of the hull by adjusting the trim balance by injecting seawater into the seawater tank. Equipped with these rudder to enable agile operation underwater.

Conventionally, the sub rudder is arranged on the side surface of the bridge, and the vertical rudder and the horizontal rudder are generally arranged in a pair of crosses on the stern.
In recent years, as the size of the hull increases, in order to ensure the effectiveness of the rudder, it is necessary to increase the rudder in the longitudinal rudder direction and the lateral rudder direction in order to ensure the effect on the rudder. However, in this case, in order to prevent the rudder from being damaged by reducing contact with the rudder quay and the bottom of the sea when landing, the rudder is bridged to prevent the rudder from being damaged, and to maintain excellent motion performance. In addition to the arrangement on the side, the number of four rudders arranged in an X-shape in the oblique 45 ° direction has increased in recent years.

However, when the four rudders are arranged in an X shape, the steerability in water is lower than that in which the rudders are arranged in a cross shape.
On the other hand, an underwater navigation device (Patent Document 1) having a structure in which a wing can be bent is known, but the rudder mounting angle can be freely changed between a cross shape and an X shape. There has never been anything that can be done. In addition to this, a representation of a steering method when four rudders are arranged in an X-shape (Patent Document 2), and a submerged rudder to a bridge to reduce wave-making resistance due to a submerged rudder placed on the bridge. A submersible craft that can be stowed (Patent Document 3) is also known, but again, the rudder mounting angle could not be freely changed.

An embodiment of a submersible craft according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the hull 2 of the submersible craft 1 according to the present embodiment is provided with a drive source such as an engine and a motor, and the power from the drive source is arranged at the stern. 5 is rotated to obtain propulsive force. In the present embodiment, the rudder 4 is arranged on the bridge 3 protruding upward from the hull 2, and a ballast tank (not shown) for diving is arranged in the hull 2.

  As shown in FIGS. 2 and 3, the stern portion of the submersible craft 1 according to the present embodiment partitions the hull 2 of the submersible craft 1 with a metal outer plate 12 with respect to the outside sea. A gear box 16, which is a support member having a space inside, is disposed in the hull 2 so that a part thereof is exposed to the outside from the opening 12 </ b> A opened in the outer plate 12. Further, a rudder shaft portion 14A formed in a shaft shape protrudes from the base end portion of the plate-shaped rudder plate 14 formed in a trapezoidal shape in FIG. 2 and is exposed to the outside of the submersible boat 1 in the gear box 16. The rudder shaft portion 14 </ b> A is inserted into the portion, passes through the internal space, and extends to the other end side of the gear box 16. The rudder shaft portion 14A is rotatably attached to the gear box 16 in such a manner that both ends of the rudder shaft portion 14A are rotatably supported by bearings 18 installed in the gear box 16. .

  As shown in FIG. 3, the outer shape of the gear box 16 is formed in an arc shape except for the insertion portion of the rudder shaft portion 14A and the portion where the bearing 18 exists, and the sliding member 19 shown in FIG. The gear box 16 can be rotated in the hull 2. A first screw cylinder 20 having a multi-threaded screw formed on the outer periphery is attached to the right side of the gear box 16 in FIG. 2, and a first hydraulic cylinder is a steering unit angle changing means driven by a control device (not shown). 22 is arranged. A first screw mechanism 24 having an internal thread engaging with the first screw shaft 20 on the inner peripheral side is provided at the tip of the piston 22 </ b> A protruding from the first hydraulic cylinder 22.

  When the hydraulic oil is fed from the port 22B at either end of the first hydraulic cylinder 22 and driven, the first screw mechanism 24 is reciprocated along the direction of the arrow in FIG. The first screw shaft 20 meshed with 24 rotates. At this time, since the first screw shaft 20 is a multi-threaded screw, the first screw shaft 24 rotates without any problem as the first screw mechanism 24 reciprocates. As a result, the gear box 16 is rotated together with the first screw shaft 20, and accordingly, the mounting angle θ of the rudder plate 14 protruding from the gear box 16 with respect to the hull 2 is perpendicular to the horizontal direction shown in FIG. It changes in the range of 90 ° to the direction.

On the other hand, a steering system 28 that rotates the rudder shaft portion 14A and changes the rudder angle by the rudder plate 14 is disposed inside the outer plate 12, and the steering system 28 will be described below.
A bevel gear 29, which is a passive gear, is fixed to the rudder shaft portion 14A protruding from the base end portion of the rudder plate 14. Further, the second screw shaft 30 is rotatably supported by the gear box 16 via a bearing 33 so as to extend in a direction orthogonal to the rudder shaft portion 14A. A bevel gear 31 that is a drive gear is fixed to the right end of the second screw shaft 30 in FIG. 2, and the bevel gear 31 meshes with the bevel gear 29. For this reason, the gear box 16 accommodates the bevel gear 29 and the bevel gear 31.

  However, a multi-threaded screw is formed on the outer periphery of the left end portion of the second screw shaft 30 protruding from the gear box 16. A second hydraulic cylinder 32 serving as a rudder angle changing means is disposed on the left side of the gear box 16 in FIG. 2, and the second end of the piston 32A protruding from the second hydraulic cylinder 32 has a second end. A second screw mechanism 34 having an internal thread meshing with the screw shaft 30 on the inner peripheral side is provided.

When the hydraulic oil is fed and driven from the port 32B at either end of the second hydraulic cylinder 32, the second screw mechanism 34 is reciprocated along the direction of the arrow in FIG. The second screw shaft 30 meshed with 34 rotates. At this time, since the second screw shaft 30 is a multi-thread screw, the second screw shaft 30 rotates without any problem as the second screw mechanism 34 reciprocates.
As a result of the above, as the second screw shaft 30 is rotated, the bevel gear 31 is rotated, and the bevel gear 29 engaged with the bevel gear 31 is rotated, so that the rudder shaft portion 14A and the rudder plate 14 are The rudder angle of the rudder plate 14 is changed by rotating the necessary amount around the X axis, which is the central axis of the rudder shaft portion 14A.

  As described above, the steering system 28 includes the bevel gear 29, the bevel gear 31, the second screw shaft 30, the second screw mechanism 34, the second hydraulic cylinder 32, and the like. In the present embodiment, the first screw shaft 20 and the second screw shaft 30 are arranged coaxially on the Y axis connecting them, and the first hydraulic cylinder 22 is attached to the hull 2 of the rudder plate 14. When the angle θ is changed, the rudder plate 14 is rotated around the axial center line (Y axis) of the screw shafts 20 and 30.

  The mechanism shown in FIGS. 2 and 3 is arranged corresponding to each of the four rudder plates 14, and each rudder plate 14 can be set to an arbitrary mounting angle θ, respectively. The rudder angle can be changed.

Next, the operation of the submersible craft 1 according to the present embodiment will be described below.
According to the submersible craft 1 according to the present embodiment, when the steering system 28 is operated, the four rudder plates 14 are rotated around the rudder shaft portion 14A, respectively, so that not only free navigation at sea, The rudder angle changes so that it is possible to navigate freely in the horizontal direction or the vertical direction in the sea.

  The steering system 28 includes not only the bevel gear 29 and the bevel gear 31 housed in the gear box 16 but also the second screw shaft 30, the second screw mechanism 34, the second hydraulic cylinder 32, and the like. As the second hydraulic cylinder 32 reciprocates, the second screw shaft 30 is rotated, and the rudder plate 14 is steered by meshing of the bevel gear 31 and the bevel gear 29.

  On the other hand, by driving the first hydraulic cylinder 22 having the first screw mechanism 24 that meshes with the first screw shaft 20, the gear box 16 is rotated in accordance with the rotation of the first screw shaft 20 attached to the gear box 16. And the bevel gears 29 and 31 accommodated in this gear box 16 rotate integrally, and the mounting angle θ of the steering plate 14 changes.

  As described above, according to the submersible craft 1 according to the present embodiment, the mounting angle θ of the rudder plate 14 with respect to the hull 2 can be changed, and the optimal mounting angle θ of the rudder plate 14 can be always set. Accordingly, by changing the mounting angle θ of the steering plate 14 in the range of 90 ° from the horizontal direction to the vertical direction, the steering plate 14 can be freely arranged between the cross-shaped arrangement and the X-shaped arrangement. It can also be changed. However, the attachment angle θ may be changed beyond the range of 90 °.

Specifically, as the attachment angle θ shown in FIG. 3 of the rudder plate 14 with respect to the hull 2 changes, the function of the longitudinal rudder and the function of the lateral rudder are respectively shared by the respective rudder plates 14 existing, for example. It is possible to arrange in the X-shape shown in FIG. 1, thereby reducing the possibility of damage to the rudder due to an accident and maintaining exercise performance even when some rudder is broken.
On the other hand, when the steering performance is to be improved, the mounting angle θ of the four rudder plates 14 with respect to the hull 2 is similarly changed so that each rudder plate 14 has the function of the vertical rudder and the function of the lateral rudder. It is conceivable to arrange them in a cross shape so that they are allotted to each other. From the above, it is possible to reduce the rudder area and volume of the rudder plate 14 by improving the steerability, so that the resistance to the hull 2 including the rudder plate 14 can also be reduced.

  On the other hand, in the present embodiment, the first screw shaft 20 and the second screw shaft 30 are arranged coaxially, the sliding member 19 is installed in the gear box 16, and the first hydraulic cylinder 22 is steered. When the mounting angle θ of the plate 14 with respect to the hull 2 is changed, the rudder plate 14 is rotated around the screw shafts 20 and 30. Therefore, the mounting angle can be easily set using the screw shafts 20 and 30 as fulcrums. θ can be changed. In addition, since the first screw shaft 20 and the second screw shaft 30 can be rotated independently, the change in the rudder angle and the change in the mounting angle θ of the rudder plate 14 with respect to the hull 2 can be made simultaneously. it can.

Next, a first modification of the submersible craft according to the present invention will be described below with reference to FIG.
As shown in FIG. 4, a mechanism having the same structure as that of the above-described embodiment is arranged in the hull 2 of the submersible craft 1 according to this modification. However, in this modification, the first screw shaft 20, the first hydraulic cylinder 22, the first screw mechanism 24, and the like are not provided. Accordingly, instead of attaching the first screw shaft 20 to the gear box 16, the steering unit angle is changed. A rotating shaft 40A of an actuator such as a motor 40 as a changing means is attached.

  For this reason, when the motor 40 is driven by a control device (not shown) and the rotating shaft 40A rotates, the gear box 16 rotates together with the rotating shaft 40A, and accordingly, the rudder protrudes from the gear box 16. The mounting angle θ of the plate 14 with respect to the hull 2 changes in the same manner as described above.

  As described above, also in this modification, the arrangement of the rudder plate 14 can be freely changed between the cross-shaped arrangement and the X-shaped arrangement, and accordingly, the rudder board 14 is arranged in the X-shape. Therefore, it is possible to reduce the possibility of damage to the rudder due to an accident and to maintain the exercise performance even if some rudder is damaged, and to improve the steering performance by arranging it in a cross shape. Is also possible.

Next, a second modification of the submersible craft according to the present invention will be described below with reference to FIGS.
As shown in FIGS. 5 and 6, in the steering system 28 of this modification, both end portions of a rod-shaped ram shaft 41 are respectively housed in two hydraulic cylinders 46 that are steering angle changing means. The ram shaft 41 is driven by hydraulic pressure so as to reciprocate on the same axis. However, the two hydraulic cylinders 46 are integrally attached to a substantially cylindrical bracket 50 as a support member, and the bracket 50 and the two hydraulic cylinders 46 are connected by the sliding member 19 installed on the outer peripheral surface of the bracket 50. It is supported in the hull 2.

  A ram pin 44 protrudes from the central large-diameter portion of the ram shaft 41, and this ram pin 44 is fitted into the fork portion 42A of the fork-like chiller 42. The rudder shaft portion 14A of the rudder plate 14 is a key 48 and this fork. The chiller 42 is fixed to the base end side. When hydraulic pressure is applied to any one of the hydraulic cylinders 46 (for example, when hydraulic pressure is applied to the right hydraulic cylinder 46), the fork via the ram pin 44 moves as the ram shaft 41 moves as indicated by the arrow A in FIG. The movement is transmitted to the chiller 42, the fork-like chiller 2 rotates as indicated by arrow B in FIG. 5, and the rudder plate 14 including the rudder shaft portion 14 A fixed to the fork-like chiller 42 rotates as indicated by arrow B. Is done.

  On the other hand, as shown in FIGS. 5 and 6, the present modified example is also provided with a first screw shaft 20 </ b> B attached to the bracket 50, a first hydraulic cylinder 22 having a first screw mechanism 24 that meshes with the first screw shaft 20, and the like. ing. Therefore, also in this modification, when changing the attachment angle θ of the steering plate 14, the bracket 50 including the two hydraulic cylinders 46, the steering plate 14 and the like is rotated.

Next, an application example of the submersible craft 1 according to the present embodiment will be described below.
As shown in FIG. 7A, the four rudder plates 14 can be first arranged in an X shape. In addition, the following variations are also possible. For example, as shown in FIG. 7 (B), the two rudder plates 14 are vertically directed toward the upper side in the vertical direction, and the two rudder plates 14 are obliquely directed at 45 ° obliquely downward. be able to. Further, as shown in FIG. 7 (C), in contrast to FIG. 7 (B), the two rudder plates 14 are vertically directed toward the lower side in the vertical direction, and the two rudder plates 14 are inclined upward 45. It can be an oblique rudder directed in the direction of °. Further, as shown in FIG. 7 (D), the two rudder plates 14 can be vertically steered in the vertical direction, and the two rudder plates 14 can be laterally steered in the horizontal direction. By setting the direction of the rudder plate 14 in this way, it becomes the same as the conventional cross-shaped arrangement.

  FIG. 8 also shows four types of variations. For example, as shown in FIG. 8 (A), one rudder plate 14 can be turned to a vertical rudder upward in the vertical direction, and three rudder plates 14 can be turned to a horizontal rudder in the horizontal direction. Further, as shown in FIGS. 8B to 8D, the two rudder plates 14 are set to the vertical rudder with the upper side in the vertical direction, and the other two rudder plates 14 are set in the horizontal direction or the vertical direction. Can be directed.

  FIG. 9 also shows four types of variations. For example, as shown in FIGS. 9 (A) and 9 (B), the two rudder plates 14 are set to a vertical rudder with the lower side in the vertical direction, and the other two rudder plates 14 are set to the horizontal direction or the vertical direction. Can be directed to. Further, as shown in FIGS. 9C and 9D, the two rudder plates 14 are laterally directed toward the right side in the horizontal direction, and the other two rudder plates 14 are set in the horizontal direction or the vertical direction. Can be directed.

  From the above, according to the submersible craft of the present invention, it is possible to have many variations of the use of the rudder that a conventional submersible cannot have. Even if there are many variations in this way, it is conceivable to change the rudder angle by computer control so that it can navigate freely in the horizontal or vertical direction in the sea. Further, it is conceivable that computer control is also used when the change in the rudder angle and the change in the angle at which the rudder plate is attached to the hull are simultaneously performed.

  In addition, although the submersible craft of the above embodiment has a structure in which all the mounting angles of the four rudder plates can be changed, only one of the mounting angles may be changed. Further, in the above embodiment, the gear box 16 is arranged with respect to the hull so that the neutral state of the rudder plate is 45 °, but the neutral state of the rudder plate is in the horizontal direction and the vertical direction. In addition, the gear box may be arranged with respect to the hull. As the power transmission means for steering, bevel gears are employed as the drive gear and the passive gear, but other types of gears may be used, and power transmission means other than gears may be used.

On the other hand, the material of each member may be a metal material such as a steel material, but may be another metal material such as a titanium alloy material in order to withstand higher water pressure.
The embodiment according to the present invention has been described above, but the present invention is not limited to the embodiment, and various modifications can be made without departing from the spirit of the present invention.

  The present invention can be applied to the steering portion of a submarine or submarine.
