Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a buoyancy control device and submarine including the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buoyancy control device and a submarine, and more particularly, to a buoyancy control device that facilitates buoyancy direction control and a submarine having the buoyancy control device.

The submarine uses a buoyancy control to operate the water. In addition, if necessary, the direction of the neutral buoyancy can be shifted to a function or a stern of the submarine to facilitate submergence or floatation of the submarine.

Generally, the buoyancy control device of the submarine is a structure that allows the sea water to flow into and out of the submarine. However, the buoyancy control system with such a structure may deteriorate the operational stability and reliability of the submarine. In addition, since the buoyancy control device having such a structure can introduce foreign substances together with the circulation of seawater, the submarine vessel may be damaged due to foreign matter.

In addition, the buoyancy control device having such a structure consumes a considerable amount of power to circulate the seawater, thus deteriorating the navigation performance of the submarine.

On the other hand, Patent Document 1 is a prior art related to the present invention. Patent Document 1 discloses a water treatment apparatus for circulating water through a ballast tank. However, such a water treatment device has a structure for inflowing and discharging water from the outside, which increases the fluid resistance of the ship in the same manner as described above, thereby hindering the ship's speed and direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In describing the present invention, it is to be understood that the terminology used herein is for the purpose of describing the present invention only and is not intended to limit the technical scope of the present invention.

In addition, throughout the specification, a configuration is referred to as being 'connected' to another configuration, including not only when the configurations are directly connected to each other, but also when they are indirectly connected with each other . Also, to "include" an element means that it may include other elements, rather than excluding other elements, unless specifically stated otherwise.

FIG. 1 is a configuration diagram of a buoyancy control device according to an embodiment of the present invention, FIGS. 2 and 3 are views showing an operating state of a buoyancy control device for a function downward state and a submersible posture of the buoyancy control device according to the present invention, And FIG. 5 is a view showing the operating state of the buoyancy control device for the function upward state and the submersible posture of the submarine accordingly.

Referring to FIG. 1, a buoyancy control apparatus 100 according to an embodiment of the present invention will be described.

The buoyancy control apparatus 100 according to the present embodiment may include a guide chamber 110, a mass member 120, a first driving means 130, and a second driving means 140. In addition, the buoyancy control device 100 may further include a shock absorbing member 150 as needed. The buoyancy control device 100 may further include a control unit (not shown) for controlling the operation of the driving means 130 and 140. In addition, the control unit may include a sensing sensor for sensing the attitude of the buoyancy control device 100. [ Here, the detection sensor may sense in which direction the buoyancy control device 100 is inclined. For example, the detection sensor may be configured to detect whether the buoyancy control device 100 is ahead of the buoyancy control device 100 (left in FIG. 1) To be detected.

The guide chamber 110 may have a cylindrical shape elongated in one direction. However, the shape of the guide chamber 110 is not limited to a cylindrical shape, and may be changed into each column or other shape as necessary. The guide chamber 110 may be substantially elongated along the longitudinal direction of the submarine. In other words, one end (left side in FIG. 1) of the guide chamber 110 is close to the function of the submarine, and the other end (right side in FIG. 1) can be close to the submarine.

The guide chamber 110 may have a structure in which both ends thereof are opened, and may have a predetermined space therein. Here, the space is elongated along the longitudinal direction of the guide chamber 110 and can accommodate a predetermined member. In addition, a protrusion 112 extending along the longitudinal direction may be formed in the space. Here, the protrusion 112 may guide the member mounted on the guide chamber 110 to move along the longitudinal direction of the guide chamber 110.

The mass member 120 may be mounted in the guide chamber 110. In other words, the mass member 120 can be mounted in the inner space of the guide chamber 110 and linearly moved along the longitudinal direction of the guide chamber 110. For this, the mass member 120 may be formed with a groove 122 into which the protrusion 112 of the guide chamber 110 is inserted. Therefore, the mass member 120 can linearly move stably along the longitudinal direction of the guide chamber 110 by the engagement of the protrusion 112 and the groove 122. The protrusions 112 of the guide chamber 110 and the grooves 122 of the mass member 120 can be omitted in a range in which the linear movement of the mass member 120 is ensured.

The mass member 120 may be a solid state material having a predetermined mass. For example, the mass member 120 may be a metallic material or a non-metallic material having a predetermined mass. However, the material of the mass member 120 is not limited to a metal or a non-metal material, and may be changed to another material capable of maintaining a solid state at room temperature.

The mass member 120 may be formed with a through hole 124 substantially parallel to the longitudinal direction of the guide chamber 110. The through hole 124 can eliminate pressure imbalance inside the guide chamber 120 that may occur when the mass member 120 moves to one or the other end of the guide chamber 120. The through hole 124 provides a passage through which the air in the guide chamber 110 can move freely to both sides of the mass member 120 so that the pressure of one end of the guide chamber 110 and the pressure of the other end are always The same can be maintained.

The first driving means 130 may be mounted on one end of the guide chamber 110. However, it is not necessary that the first driving means 130 is directly mounted in the guide chamber 110. If the first driving means 130 can move the mass member 120 to one end of the guide chamber 110, Can be mounted.

The first driving means 130 can move the mass member 120 to one end of the guide chamber 110. [ To this end, the first driving means 130 may include a first motor 132, a first reel 134, and a first steel wire 136. Here, the first motor 132 may be a decelerating motor having a built-in decelerator, which can rotate in the forward and reverse directions. The first reel 134 may be mounted to the first motor 132 and may be configured to freely wind or unwind the first steel wire 136.

The first steel wire 136 may connect the first reel 134 and the mass member 120. In other words, one end of the first wire 136 may be fixed to the first reel 134, and the other end thereof may be fixed to one side of the mass member 120. Accordingly, when the first motor 132 rotates in the forward or reverse direction, the first steel wire 136 can be wound on the first reel 134 to move the mass member 120 to one end of the guide chamber 110 .

The second driving means 140 can move the mass member 120 to the other end of the guide chamber 110. [ To this end, the second driving means 140 may include a second motor 142, a second reel 144, and a second wire 146. Here, the second motor 142 may be a decelerating motor that can rotate in the forward and reverse directions and has a built-in speed reducer. The second reel 144 may be mounted to the second motor 142 and the second wire 146 may be freely rolled or unwound.

The second wire 146 may connect the second reel 144 and the mass member 120. In other words, one end of the second steel wire 146 may be fixed to the second reel 144, and the other end may be fixed to the other side of the mass member 120. Therefore, when the second motor 142 rotates in the forward or reverse direction, the second steel wire 146 can be wound on the second reel 144 to move the mass member 120 to the other end of the guide chamber 110 .

The shock absorbing members 150 may be mounted on both ends of the guide chamber 110, respectively.

The force absorbing member 150 is made of a foamable material or a material free from elongation shrinkage and can absorb an impact that may occur when the mass member 120 moves abruptly to one or the other end of the guide chamber 110. For reference, the shock absorbing member 150 may be omitted as needed.

The buoyancy control device 100 configured as above can change the relative position of the mass member to adjust the buoyancy direction, so that buoyancy can be adjusted quickly. For reference, the buoyancy control apparatus 100 according to the present embodiment may be mounted on a submarine or other diving apparatus, thereby improving the speed of diving or floating of a submarine or other diving apparatus.

2 and 3, the submergence attitude of the submarine using the buoyancy control device 100 will be described, and the floating attitude of the submarine using the buoyancy control device 100 will be described with reference to FIGS. 4 and 5. FIG.

The buoyancy control device 100 may adjust the position of the mass member 120 to facilitate the diving of the submarine 200 on which the buoyancy control device 100 is mounted. For example, the buoyancy control device 100 operates the first driving means 130 and the second driving means 140 to move the mass member 120 forward (to the left in FIG. 2) of the buoyancy control device 100, . The first motor 132 of the first driving means 130 rotates so that the first steel wire 136 is wound on the first reel 134 and the second motor 132 of the second driving means 130 rotates 142 can rotate so that the second wire 146 is released from the second reel 144 to move the mass member 120 forward of the guide chamber 110 (see FIG. 2).

In this case, since the function 210 of the submarine 200 mounted with the buoyancy control device 100 is heavier than the stern 220 (see FIG. 3), the submarine 200 can be changed to a position facing the deep sea. In addition, since the propulsive force of the propeller 230 is directed downward, such a posture can facilitate the diving of the submarine 200.

In contrast, the buoyancy control device 100 can adjust the position of the mass member 120 to facilitate the floating of the submarine 200 on which the buoyancy control device 100 is mounted. For example, the buoyancy control device 100 operates the first driving means 130 and the second driving means 140 to move the mass member 120 rearward (right side in FIG. 4) of the buoyancy control device 100, . The first motor 132 of the first driving means 130 rotates so that the first steel wire 136 is released from the first reel 134 and the second motor 132 of the second driving means 140 142 can be rotated so that the second wire 146 is wound on the second reel 144 to move the mass member 120 to the rear of the guide chamber 110 (see FIG. 4).

In this case, the submarine 200 mounted with the buoyancy control device 100 is heavier than the function 210 of the submarine 220 (see FIG. 5), so that the submarine 200 can be changed to a position facing the sea. Such an attitude makes the propulsive force of the propeller 230 upward, so that the submarine 200 can be easily lifted.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the following claims. The present invention is not limited thereto.
