Description

Submarine {SUBMARINE}

The present invention relates to a submarine.

In conventional submarines, in particular military submarines, the entry into the pressure hull is via the entrance provided in the tower, which must be entirely above the water, otherwise water can penetrate the pressure hull. Although other entrances may be provided depending on the type of construction, they are only used for maintenance purposes or for unloading loads or are only open at a port or marina and the cross-sectional shape is not suitable for human entry or exit.

Activities on military submarines are more extensive and for this reason it is desirable to allow the entrance structure on the one hand to be organic with the other devices in the submarine, and on the other hand to allow divers or small vessels to enter and exit. .

Although in the case of military submarines it is known to send divers out via torpedo tubes, this method is not acceptable for safety reasons because of the many risks due to the position and size (small cross-sectional area) of torpedo tubes. Moreover, sending divers through torpedo tubes can be problematic, and in some cases, torpedo tubes can't be used, which can cause submarine performance.

The object of the present invention is therefore to improve the submarine in terms of its availability, in particular allowing the diver to enter and exit the diver in a simple manner.

According to the present invention this object is achieved by the features of claim 1.

The basic idea of the present invention is to provide a submarine comprising a long pressure hull with a pressure hull (pressure ante chamber) with the function of an anti-chamber, and transverse such pressure and chamfer with respect to the longitudinal axis of the pressure hull. Will be placed in the direction. In order to be able to perform the function of the anti-chamber, the pressure anneal chamber has an outside entrance which can be hermetically sealed to prevent leakage of pressure, and likewise an entrance to the pressure hull which can be hermetically sealed to prevent leakage of pressure. Have Furthermore, after closing the entrance to the pressure hull, fill the pressure ante chamber with water so that the pressure of the pressure ante chamber is equal to the external pressure. Appropriate technical means to be provided are provided. In addition to the above means, valve control means are provided which allow the simultaneous opening of these entrances and exits.

The transverse placement of the pressure and chamber relative to the longitudinal axis of the pressure hull offers a design possibility to allow the entrance to be large enough to allow a person or small boat to pass through it. This transverse arrangement requires only relatively small installation space in the submarine. In the new design, the space required for this transverse arrangement can be obtained by extending the boot in the longitudinal direction, and in the case of existing submarines, free space for additional systems can be provided by suitable arrangement through retrofitting. You can do that.

The pressure anti-chamber according to the present invention may be disposed in the pressure hull completely or partly as a part penetrating the pressure hull, but may be disposed as a separate pressure hull outside the pressure hull. The pressure ante chamber is preferably arranged in the area of the tower and in particular connected in tangential direction to the pressure hull, directly or via an entry tunnel. In the tower area, at least enough space is formed so that the pressure < RTI ID = 0.0 > antichamber < / RTI > according to the present invention can be arranged transversely with respect to the longitudinal axis of the pressure hull so that one or more divers can pass through the pressure and antichamber. have. This configuration does not require additional space in the pressure hull and, on the other hand, has little disadvantage as it can accommodate the pressure ante chamber outside the existing tower.

If the pressure ante chamber is arranged in the pressure hull, this structure can be configured in the area in which the tower is placed. In particular, this area is particularly advantageous because it is located in close proximity to the command center, which is typically located within the tower area, and allows good communication with the command center without expensive technical equipment.

With this configuration in the pressure hull, the pressure anneal chamber is integrally formed with the pressure hull such that the pressure hull, in particular the cylindrical pressure hull casing, can be constructed simultaneously with the parts of the pressure anneal chamber. In this way, the effective space is effectively used. However, the structure is relatively robust given the necessary reinforcement. Thus, in this configuration, the cover for sealing the entrance to the outside can be configured as part of the pressure hull casing.

The pressure ante chamber is preferably elongated and has an entrance to the outside at its end. In this configuration, the entrance to the outside is relatively large, whereby divers or equipment can easily enter and exit, and the entire cross section of the pressure ante chamber and the entrance to the outside can be used.

In this configuration, a cylindrical shape with hemispherical or flat hemispherical side ends is suitable for elongate pressure and chambers. On the one hand, in order to use the space in the submarine as optimally as possible at the given machine position transversely to the longitudinal axis of the pressure hull and on the other hand, to make the structure lightweight, the pressure anti-chamber has the shape of oval or double ring in cross section. It is preferable to have. As such, the available space of the pressure and chamber can be expanded without the need to have an overly heavily armed structure.

In using the space in the pressure chamber, it is preferable to have a rectangular cross section. However, this requires costly structural reinforcement to achieve the same pressure strength as in the case of pressure anti-chambers of circular cross section. In the present invention, the rectangular parallelepiped should be understood to have a cross section or a side surface of a rectangular parallelepiped having a curved edge.

While it is good to have the cover for the doorway to the outside open or close the cross section of the pressure ante chamber as completely as possible, while the doorway to the pressure hull provides a sufficient passage for the diver to crawl. . If necessary, divers may be prepared to dive in the pressure ante chamber depending on the size of the pressure ante chamber. Also in terms of using space, if the entrance and exit of the pressure anneal chamber to the pressure hull is not configured on the end wall but on the longitudinal side wall, in the center of the pressure hull where suitable free movement can be made in the space of the submarine Free access can be made, and access can be very restricted in other areas.

The pressure anti-chamber according to the present invention is configured in the form of a decompression chamber so that the pressure and pressure of the pressure-anti-chamber becomes the desired pressure in case of a diving accident or other problems related to the pressure. To prevent the occurrence of embolism by the (塞 栓 症). In this way, the pressure and the pressure of the chamber can be adjusted to the desired pressure, and appropriate control can be made so that the pressure level gradually reaches a normal pressure level. Moreover, communication means may be provided to observe and control the biological functions of the person in the pressure and chamber.

In addition, the pressure ante chamber of the present invention can be configured to accommodate the submersible in the pressure ante chamber through a suitable guide without any other problem. In the present invention, the submersible means a small unmanned or manned submarine, and the submersible vessel means that the submersible can be driven by the underwater.

In order to configure the pressure and anti-chamber according to the present invention in an existing submarine is usually insufficient space. Such equipment therefore always involves the extension of other devices or equipment. Moreover, when installing such a facility in the existing pressure hull, the opening of the pressure hull needs to be wide, which makes it difficult to arrange in relation to the manufacturing technology. Integrating the pressure anneal chamber into the existing pressure chamber and resealing the pressure hull can result in roundness in these areas, which significantly impairs strength. In general, retrofitting the tower area is excluded for space reasons. According to the present invention, in order to install a pressure anti-chamber by modifying an existing submarine, first, the submarine is divided into transverse sections with respect to its longitudinal axis, and a portion of the submarine is already manufactured. The airtight and tightly integrated parts of the remaining pressure hull to prevent leakage. This method, on the one hand, additionally requires the necessary installation space for the pressure and chamber, and on the other hand, the pressure hull is not disturbed by its support structure and is secured through the peripheral welding line using suitable welding and reinforcement on the inside. There is an advantage to this. This method also has the advantage that the submarine section to be integrated, including the pressure and chamber, can be prefabricated in the form of modules so that the necessary equipment can be assembled and tested externally without being assembled in the limited space inside the submarine hull. . Moreover, this modular submarine section is also applied to submarines that are being retrofitted, as in the case of newly designed submarines, to reduce manufacturing costs.

In this way, the submarine is divided laterally in the tower area and the submarine section to be integrated can be integrated in line with the existing outer surface in the longitudinal direction. The selection of these sections in the tower area allows the necessary installation space for the pressure and chamber to be established and also allows for extended equipment to be accommodated, or to accommodate new weapon systems and sensors, such as automatic sampling of seawater specimens. It also provides a spatial advantage that allows free space to be formed that can be used as an additional space for crew. Such additional components may be in the field of communication equipment, communication reconnaissance and opto-electronic components or weapon guidance systems. Space may also be used to accommodate equipment, mines, rubber lifeboats or other packages or diving devices or measurement and analysis equipment.

Referring to the present invention in more detail based on the accompanying drawings as follows.

The submarine 1 shown in FIG. 1 (a) is formed over a nearly full length and consists of a cylindrical pressure hull 2 which forms an airtight space for the crew and the device. The propeller 3 and the steering apparatus 4 are provided in the ship. The tower 5 extends from the middle of the pressure hull 1 to the upper side, which is a conventional structure and includes stations for activity and observation on the water surface as well as in underwater activity.

According to the prior art, the submarine shown in Fig. 1 (a) can only enter and exit through the central entrance of the tower (5). The submarine 1 is divided transversely in the area of the tower 5 in order to integrally configure the entry and exit chamber for allowing entry and exit of a person or equipment in the submerged state of the submarine. The dividing line 6 is marked on this submarine. After subdividing the two divided submarine sections, a submarine section 7 is inserted between them, which are indicated by hatching in Fig. 1 (b) and the extension of the cylindrical pressure hull 2 and its upper part. It includes an extension of the tower (5). In submarines, submarine sections 7, which can be integrated as they are separated along the dividing line 6, or which can be integrated from the outset in relation to this design in newly designed submarines, are the longitudinal axis of the pressure hull 2. And an additional pressure hull, called pressure antichamber 9, which is arranged transverse to (8).

3 shows, for example, two components of the pressure antamber 9a in the form of a pressure antamber 9a in the area of the tower 5 and a pressure antamber 9b in the lower area of the tech 10. have. The pressure and antichambers 9a and 9b are elongated but are formed long in the transverse direction with respect to the longitudinal axis 8 of the pressure hull 2. One end (right side in FIG. 3) is provided with a doorway 11 to the outside. The entrance 11 to the outside is rotatably mounted to the pressure anti-chamber 9 and is provided with a lid 12 for hermetically sealing the pressure anti-chamber to the outside. In the upper configuration of FIG. 3, when the cover 12 is closed, the outer portion of the cover 12 is covered with a casing portion 13 to coincide with the streamlined outer surface of the tower 5.

The other entrance 15, that is, the entrance to the pressure hull 2 side, is formed on the side wall 14 of the pressure ante chamber 9a. This doorway 15 can also be closed tightly by a shutter (not shown). The pressure ante chamber configured in this way allows the diver 16 or the boat 17 to enter and exit, for example, as illustrated in FIGS. 2 and 3.

The diver can access the pressure and chamber 9a in a state in which the diver is hermetically closed by the cover 12. After closing the entrance 15 for entering and exiting the pressure hull 2 side, the pressure ante chamber is gradually adjusted to external pressure and filled with water to open the cover 12 so that the diver can leave the pressure ante chamber 9a. do. The diver's attempt to enter the submarine side from underwater occurs in the reverse order. First, the pressure is gradually adjusted to the pressure level in the pressure hull 2 before the water filled in the pressure ante chamber 9a is discharged and the entrance 15 is opened. do.

In the configuration of the pressure anneal chamber 9b shown in the lower side of FIG. 3 and configured to be larger in the lower portion of the deck 10 in the pressure hull 2 than the pressure antamber 9a in consideration of the space, the lid 12 is provided. Although not functionally included in the actual pressure hull 2, it is operatively coupled to the pressure hull portion 18 which is sealed to conform to the outer surface when the cover 12 is closed by forming part of the outer surface. The pressure ante chamber 9b also includes an entrance and exit 15 formed in the side wall 14 corresponding to the upper portion in FIG. 3. The size of the pressure and chamber (9b) is a size that can be entered by several people through this. The pressure and chamber can accommodate or enter devices such as mines, location devices, etc. instead of humans. If necessary, appropriate handling devices may be arranged in the pressure and chamber 9 to allow the equipment to be handled in an automated manner, even if the diver is not suitable for exiting the submarine.

3 shows two pressure and antichambers 9a and 9b which can be provided either selectively or all together in the section 7 of the submarine. Such a configuration has the advantage that the access to the command center can be made at the shortest distance by actually being disposed in a position close to the command center 19.

In another embodiment of FIG. 2, a submersible section 7 of which is part of the pressure hull 9 but which is optionally provided and located below the deck 10 shows as a separate pressure and chamber 9c. have. However, this configuration, which provides the maximum space for the pressure antichamber 9c, requires significant reinforcement in the region of the pressure antichamber 9c. Here, the entrance 11 to the outside is composed of a pressure hull portion 18, but in this case the entrance should be of a pressure-resistant waterproof.

The configuration of the pressure and antichamber 9 preferably has a circular cross-sectional shape as shown in FIG. However, the size of the space is relatively small due to the lower effective height of the deck 10, as shown in FIGS. 4 (a)-(d). In view of this point, the configuration of Fig. 4 (a) showing a hull composed of two cylinder casings in which the pressure and anti-chamber intersect as a double ring cross section is more preferable. Considering the shape, this configuration change requires additional reinforcement, unlike that shown in FIG. 4 (b). If such additional reinforcement is made, it may be advantageous to have a rectangular cross-sectional shape of the space in the pressure and chamber as shown in FIGS. 4 (c) and 4 (d). However, these configurations require that they be significantly enhanced because they are inherently less stable in shape.

As mentioned above, the pressure ante chamber 9 can also be used as a pressure reducing chamber and can be designed accordingly. The configuration of the pressure and chamber 9 inside or on top of the submarine 1 offers various applicability of military or civil submarines.

As such, the present invention increases the availability of the submarine, and provides a submarine that allows the diver to enter and exit in a simple manner, in particular in the submerged state.
