Description

[0001] HYBRID WET / DRY MIDGET SUBMARINE [0002]

[0001] The present invention relates to a dry wet hybrid submersible, and more particularly, it relates to a wet-humid hybrid submersible vehicle in which a whole submergence chamber of a submersible can be used as a single pressure chamber having a plurality of functions such as a crew chamber function, a lockout chamber function, Of course, it is about a wet hybrid hybrid submersible that can greatly shorten the time required for entering and exiting the crew when the submersible is submerged.

Generally, a submarine used for submarine navigation or military use is based on an electric motor driven by a battery and is used for underwater exploration activities and military operations, have.

Therefore, the submersible is fixedly moved to the exploratory and operational area, and the submersible is separated for exploration and operation after reaching the exploration and operation area.

The conventional submersible as described above includes a hull constituted by an internal pressure structure, in which a battery, a ballast tank, a surveying instrument, a research equipment, and the like are mounted, a stern section in which a propeller is coupled to a propulsion motor disposed behind the hull, A navigation system capable of detecting a traveling direction and an underwater obstacle, a bow portion formed with a sonar detector, and a crew room on which a crew can ride on the center of the hull.

On the other hand, the above-described submersible can be classified into a dry submersible vessel in which seawater does not flow into the ship and a wet submersible vessel into which seawater can flow.

The dry submersible is provided with a lockout chamber separately from the crew chamber, and crew members can enter and exit through the lockout chamber.

Specifically, the lockout chamber is connected to the submergence chamber of the submarine through a hatch as a separate pressure hull in the submarine. Examples of the connection and configuration are as shown in FIG.

When the crew member aboard the crew room exits to the outside of the submersible, the first and second hatches 1 and 2 are opened to enter the lockout chamber with the third hatch 3 closed, The first and second hatches 1 and 2 are closed and the seawater is introduced into the lockout chamber through a separate seawater inlet means so that the pressure and the external pressure in the lockout chamber are equal to each other, The third hatch (3) is opened and introduced into the water. At this time, seawater is introduced into the ballast tank for weight compensation corresponding to the weight of the crew member going out of the submersible.

In order for an external crew member to enter the crew room of the submersible, the above-described process may be performed in the reverse order.

The wet submersible as described above is limited in the number of crew members (2 to 3 persons) that can enter at one time due to the size limitation of the lockout chamber, so that a large number of crew members or team members can not enter at once, So that an excessive time is required for accessing the apparatus, and the efficiency of operation is hindered.

In addition, since the weight must be compensated according to the weight of the passengers entering and leaving the tank, the tank, pump, and valve for balusting must be essential, thereby increasing the weight of the entire submodule and shortening the operating time .

In addition, since various electronic equipments are installed in the crew room of the submersible, there is a disadvantage in that it is inconvenient to manufacture and operate because it has to be constructed with a double hatch structure in order to prevent seawater from entering.

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

Disclosure of the Invention The present invention has been made in view of the disadvantages of the operation of the lockout chamber used in the input / recovery of the crew in the conventional submarine, such as limitation of the personnel, time and procedure complexity, Is a hybrid dry / wet submersible designed to address the complexity of the structural and manufacturing equipment (ballast tanks) needed and the problem of hypothermia experienced by crew members during long-term underwater operation of a conventional wet submersible.

In order to compensate for the disadvantages of the prior art, a structure and function divided into a conventional submarine body, a lockout chamber and a ballast tank are realized by a single pressure hull, and a diver is operated in a dry mode from a remote site to a destination The diver is protected from hypothermia, which is a disadvantage of the submersible, and when it arrives near the destination, the hatch portion provided at the lower portion of the hull is opened to switch to the wet mode, thereby functioning as a lockout chamber. In addition, since the crew room itself can also function as a ballast system for compensating for the weight, it is characterized in that three functions are fulfilled by using a crew room as a single pressure vessel.

2 and 3, the dry and wet hybrid submersible according to one embodiment of the present invention includes a hull 100, a hatch 200, a valve 300, a pump 400, A control unit 500, and a control unit 600. [

The hull unit 100 is a part forming the overall shape of the submersible. In the hull unit 100, a passenger compartment 100S, which is a space for the passengers to ride on, is formed.

Inside the vehicle room 100S, there is a system for allowing passengers to breathe underwater, such as a navigation console, a navigation device, a communication device, a system for operating a submarine such as a controller, an underwater breathing device, And these systems are all waterproofed so that they can be protected even if seawater flows into the inside of the passenger room 100S.

The hatch unit 200 is a part for opening or closing the cushioning room 100S and is provided in the lower part of the hull unit 100 so as to communicate with the cradle room 100S, The crew member can enter and leave the crew room 100S and the outside of the submersible at the time of opening.

The valve unit 300 is a part for allowing seawater to flow naturally into the passenger compartment 100S due to a pressure difference or for allowing sea water in the passenger compartment 100S to be naturally discharged to the outside by a pressure difference, And the seawater is naturally introduced or discharged due to the difference between the pressure in the passenger compartment 100S and the sea water pressure outside the hull 100. [

The pump unit 400 is a part for pumping the seawater into the passenger compartment 100S or pumping the septic tank 100S to discharge the seawater to the outside, .

The fixing unit 500 includes a winding unit 510 provided at a lower portion of the hull unit 100, a wire 520 wound around the winding unit 510, (530) so that the position of the submersible can be fixed to a certain water area.

The control unit 600 controls the opening and closing of the valve unit 300, the pumping operation of the pump unit 400, and the operation control of the winding unit 510 of the fixing unit 500.

The control unit 600 controls the valve unit 300 to be opened so that the outer circumferential surface of the cushioning room 100S is connected to the outer surface of the hull unit 100. In addition, It is possible to control the communication between the passenger compartment 100S and the hull 100 to be blocked.

For example, when the valve unit 300 is opened and the seawater is introduced into the passenger compartment 100S, the control unit 600 controls the internal pressure of the passenger compartment 100S and the seawater outside the hull unit 100, It is possible to make the hatch unit 200 openable by controlling the pressure difference to be within a predetermined range.

The control unit 600 may control the pressure of the high pressure water supplied to the hull unit 100 to be supplied to the hull unit 100 while the difference between the internal pressure of the passenger compartment 100S and the pressure of the seawater outside the hull unit 100 is within a predetermined range, The opening of the hatch unit 200 may be facilitated by opening the oxygen tank 110 and controlling the internal pressure of the passenger compartment 100S to be higher than the seawater pressure outside the hull 100 .

The control unit 600 controls the pumping operation of the pump unit 400 so that the seawater introduced into the passenger compartment 100S is forcibly discharged to the outside of the ship 100, The seawater existing outside the passenger compartment 100 can be forced into the passenger compartment 100S.

The control unit 600 opens the high-pressure oxygen tank 110 provided in the hull unit 100 in a state where the hatch unit 200 and the valve unit 300 are closed, The internal pressure of the cushioning room 100S may be controlled to be lowered by controlling the internal pressure of the cushioning room 100S to be higher or forcing the seawater or the gas of the cushioning room 100S to be discharged to the outside through the pump unit 400 have.

In addition, the controller 600 can adjust the depth of the water in which the hull unit 100 is placed by unwinding or winding the wire 520 held by the winding unit 510.

Meanwhile, the NATO mating flange standard provided at the lower part of the hull part 100 of the submersible can be combined with the hatch of the stranded submarine when the other submarine is stranded, Can also be used as.

In addition, it is possible to retrieve in water the underwater search and the submerged water seeking the stranded ship or missing by utilizing the navigation equipment and sonar provided in the hull part of the submersible. For example, when the algae is stranded In the search structure of the ship, the crew can not move to the stranded ship, but when the submersible is used, the crew can be transported to the stranded ship.

On the other hand, the Doppler flow meter (flow sensor) on the submersible sends a "ping" (signal) and processes the information with the reflected signal. For information processing, a minimum distance of 50cm to 1m However, since the submersible of the present embodiment is equipped with the adherence stopper 120 at the bottom thereof, it is difficult to detect the position of the submerged vessel by the operation It is possible to maintain the minimum distance at all times and to maintain the position of the submersible on the sea floor in the water.

As described above, the wet-type hybrid submersible 100 including the hull section 100, the hatch section 200, the valve section 300, the pump section 400, the fixing section 500 and the control section 600 The dry mode, the wet mode, and the decompression chamber mode will be described in detail.

First, the dry mode will be described.

Conventionally, in the case of a wet-type submersible, since the seawater is introduced into the ship and the crew is always exposed to the seawater, breathing is possible only through the breathing apparatus at all times and a separate lockout chamber or ballast apparatus is not required for inputting / However, since the crew is always exposed to seawater, there is a problem that long term or long distance operation is impossible due to high physical fatigue due to hypothermia during long-term underwater operation.

The dry mode of the dry and wet hybrid submersible according to the present embodiment is a dry state in which seawater is not introduced into the inside of the passenger compartment 100S of the hull 100 and the inside of the passenger compartment 100S is dry, Since it is not exposed to cold seawater, long-term underwater operation is possible.

Such a dry mode may be achieved by discharging seawater from the inside of the passenger compartment 100S to the outside through the pump unit 400 while the hatch unit 200 is closed, 300, the pump unit 400, and the high-pressure oxygen tank 110 so that the internal pressure of the combustion chamber 100S becomes an appropriate level. That is, when the internal pressure of the passenger compartment 100S is lower than the proper level, the high pressure oxygen tank 110 is opened to increase the internal pressure of the passenger compartment 100S. If the internal pressure of the passenger compartment 100S is higher than the proper level, The internal pressure of the cushioning room 100S can be lowered by discharging the gas inside the cushioning room 100S through the unit 300 or the pump unit 400. [

The dry mode as described above enables long-time underwater operation from a remote area to the vicinity of a destination (infiltration area).

Next, the wet mode will be described.

The wet mode of the dry and wet hybrid submersible according to the present embodiment allows the seawater to be maintained in the inside of the passenger compartment 100S of the hull section 100 so that the passengers inside the passenger compartment 100S can go out, It is possible to go in and out.

In order to switch from the dry mode to the wet mode, the valve unit 300 is opened through the control unit 600, or the pump unit 400 is pumped to flow seawater into the inside of the passenger compartment 100S , And stops the pumping operation of the pump unit 400 when the seawater is almost filled in the passenger compartment 100S. At this time, as the difference between the internal pressure of the passenger compartment 100S and the sea water pressure outside the hull 100 is within a predetermined range, the hatch 200 can be opened.

It is needless to say that opening and closing of the valve unit 300 and pumping operation of the pump unit 400 as described above may be manually performed by a crew member in the crew room 100S.

On the other hand, if the valve portion 300 is kept in the open state while the seawater is almost filled in the passenger compartment 100S, the internal pressure of the passenger compartment 100S and the seawater pressure outside the hull portion 100 The seawater can be introduced into the inside of the passenger compartment 100S until they become the same state.

The difference between the internal pressure of the passenger compartment 100S and the seawater pressure outside the hull 100 is within a predetermined range or the difference between the internal pressure of the passenger compartment 100S and the sea water pressure outside the hull 100 Pressure oxygen tank 110 provided in the hull unit 100 is opened so that the inner pressure of the vehicle room 100S is slightly higher than the seawater pressure outside the hull unit 100 The opening of the hatch 200 can be more smoothly performed.

The wet mode described above is a state in which, in the water in the vicinity of the penetrating area, the crew members aboard the crew room 100S inside the submersible can go out or can enter the crew room 100S. ) Can be utilized as a lockout chamber.

In other words, conventionally, since the crews are configured to come in or out only through a separate lockout chamber, there is a problem that there is a limitation on the number of crew members (2 to 3 persons) that can be entered at one time due to the size limitation of the lockout chamber, It is inconvenient to compensate the weight in accordance with the weight of the passenger who has gone outside the submersible through a separate ballast device. However, in the wet / dry hybrid submersible of this embodiment, when the hatch 200 is opened, Since the crews of many passengers can go out at one time or enter the crew room 100S, the time required for entering and exiting the crew members can be shortened remarkably. Also, The submersible unit may be placed on the sea floor or the weight may be fixed to the sea floor to allow the submersible unit to stay at a certain depth. The crew member can easily enter and exit through the hatch 200 when the correction is performed on the sea floor, and the height of the Doppler flow meter can be maintained at a predetermined height, so that the function of the Doppler flow meter can be smoothly performed. It is advantageous in that the crew members go out or enter the crew room 100S and the sea water inside and outside the crew room 100S is compensated by itself in response to the volume of the crew member so that no additional weight compensation is required.

Next, the decompression chamber mode will be described.

Generally, when a crew moves beyond the decompression diving time at a depth of 10m or more and moves to a lower depth of water after a long period of time in water or moves to the water surface, nitrogen dissolved in the body changes into bubbles under water pressure and moves to the brain and lungs along muscles or blood vessels Thereby causing decompression sickness.

Therefore, when the diving at deep water depth exceeded the non-self-oppression limit time, nitrogen was dissolved in the body for a fixed time at the depths of 12m, 6m, and 3m, It moves to the surface of the water. At this time, additional devices for smooth gas supply and body temperature maintenance are required, and if there is no such additional device, it must be depressurized by treatment in the land pressure chamber after moving to the water surface.

As described above, in order to decompress at a predetermined water depth in water, a lot of preparations and personnel must be followed, and in the winter, there is a problem that the suffering of a crew member under treatment due to cold water temperature becomes worse.

The decompression chamber mode of the dry and wet hybrid submersible according to the present embodiment is a mode that can solve the above-described problems. The mode of operation is such that a crew member requiring decompression enters the inside of the passenger compartment 100S of the submersible, , Communication equipment, etc., so that they can receive various support during decompression.

For example, in a state where the weight 530 of the fixing unit 500 is placed on the sea floor and the valve unit 300 of the submersible in the wet mode is kept open, The wire 520 is wound or loosened through the winding means 510 so that the depth of the submergence is gradually changed to 12 m, 6 m and 3 m, So that the pressure reduction of the vehicle can be induced. During the decompression process, the crew can receive various support through a warming device, a breathing apparatus, a communication device, and the like provided inside the submersible.

As another method for reducing the pressure of the crew member, the crew member enters the submergence chamber 100S of the submersible in the wet mode of the submersible, and then discharges the seawater in the crew room 100S to the outside through the pump unit 400 Pressure oxygen tank 110 provided in the hull unit 100 is opened during the transition to the dry mode to control the internal pressure of the cushioning room 100S to be high, (100S) through the valve unit (300) and discharges the gas to the outside through the valve unit (300), the pressure in the passenger compartment (100S) So that the pressure of the crew can be reduced.

Although the present invention has been described with reference to the preferred embodiments thereof with reference to the accompanying drawings, it will be apparent to those skilled in the art that many other obvious modifications can be made therein without departing from the scope of the invention. Accordingly, the scope of the present invention should be interpreted by the appended claims to cover many such variations.
