Description

Starting device {STARTING DEVICE}

The present invention relates to a starting device for a diving body having the features specified in claim 1.

Devices of the type discussed in the present specification are arranged in modern submarines, usually in the region between the pressure hull and the outer skin surrounding the pressure hull, preferably in the region of the upper deck. Diving bodies, such as, for example, torpedo defense effects, are stored in tubular storage vessels in these devices. Thereby, the diving body in the storage container is generally embedded in a protective agent such as glycol for protection from corrosion and other environmental influences.

At the same time, these devices also serve to start the diving body, for which purpose these devices are ejected from the outlet opening of the reservoir using appropriate means. The piston-cylinder arrangement disclosed for example in DE 41 26 064 C1 is known for ejecting a diving body, using which a catch that engages on the diving body is arranged on a piston which is guided in the cylinder. The cylinder collides with the pressure medium, whereby the piston and thus the underwater body are moved out of the reservoir. However, it was previously necessary to open the exit opening of the storage container or the mouse closure to close the mouse, which generally required a pivotable cover. Large design difficulties and high manufacturing costs are known to be disadvantageous to the device for starting the underwater body.

Under this background, it is an object of the present invention to provide an apparatus for the storage and deployment of at least one underwater body which is simple in design and allows for reliable deployment of the underwater body compared to the prior art.

This object is achieved by a starting device for an underwater body having the features specified in claim 1. A more preferred form of the invention is derived from the following description, together with the dependent claims and the figures.

The starting device for an underwater body according to the invention is arranged outside the pressure hull of the submarine, preferably in the area of the upper deck. The starter includes at least one storage container for storing the diving body, which is closed on the outside by a mouse closure, and means for ejecting the diving body out of the storage container. According to the present invention, the starter includes means for ejecting a diving body, which means is also designed to serve to open the mouse closure.

The basic concept of the present invention is to provide a functional integral to the means for ejecting the diving body, which not only allows the diving body to be ejected from the storage vessel but also closes the outlet opening of the storage vessel. Allow the mouse closure to open prior to the ejection of the diving body. To this end, the movement of the means for ejecting the diving body is advantageously carried out by ejecting the diving body out of the storage container and also used to open the mouse closure. Due to this functional integrity, for the starting device according to the present invention, in contrast to this type of device known to date, no separate device is provided which is provided only for the opening of the mouse closure. Therefore, less parts are needed for manufacturing the starting device according to the present invention, which significantly reduces the labor in the manufacturing process, and hence the manufacturing cost.

Preferably the present invention devises a piston-cylinder arrangement as a means for ejection of the diving body, whereby a piston or cylinder coupled in movement with the diving body can be moved relative to the mouse closure. That is, according to the present invention, due to the pressure collision of the cylinder chamber of the cylinder, the piston movably guided therein in the case of the fixedly arranged cylinder can be moved, or moveably in the case of the fixedly arranged cylinder The guided cylinder can be moved, wherein the movable coupling of the movable piston or cylinder to the diving body is preferably carried out through a ring disposed on the piston or cylinder and engaging on the diving body. Due to the fact that the piston or cylinder is moved relative to the mouse closure, the mouse closure is moved to the piston position to release the outlet opening or, depending on the design, is broken by the piston or cylinder. Typically, the piston or cylinder coupled to the diving body upon movement is designed and / or arranged in such a way that the piston or cylinder opens the mouth closure before the diving body reaches the outlet opening of the reservoir.

The mouse closure of the storage container may advantageously be formed by a pivotable cover. This cover is preferably segmented on a storage container. The segment of this cover is useful in such a way that the cover pivots against the outer side so that it is pivoted away from the storage container in the ejecting direction of the diving body and preferably into a position to completely release the open cross section of the outlet opening. For this purpose, the segment of the cover is particularly preferably implemented in a plane common to the central axis of the piston or cylinder, the piston or cylinder being moved towards the inner side of the cover, where the segment of the cover is spaced apart from the diving body. It is arranged on the side of the piston or cylinder.

Advantageously, the cover closing the outlet opening of the reservoir is spring-biased in the closing direction. Thus, at least one spring is provided so that the cover is closed again after the submersible body leaves the storage container. In this way, too much sea water can be prevented from flowing into the storage vessel and / or into the intermediate space between the pressure hull and the outer skin of the submarine, in which the storage vessel is disposed. The spring type used to close the cover is essentially infinite. Thus, this spring can be designed, for example, as a tension spring or a pressure spring. However, particularly advantageously the torsion spring is used to connect the cover to the non-moving portion of the joint pivotally hinged and to the cover.

Advantageously, a means for reducing frictional resistance is arranged on the end of the piston or cylinder, which end is fitted to the cover to prevent damage to the cover and / or the piston or cylinder when the piston or cylinder contacts the cover. Contact. As these means for reducing frictional resistance, for example, without essentially any friction, ensuring that the piston or cylinder can slide or roll along the inside of the pivoted-open cover is for example a slider element or There is a roller.

In a more advantageous design of the starting device of the invention, the membrane forms the opening closure of the storage container. Thus, a membrane is provided which closes the entire outlet opening in a liquid-sealed manner. It is possible to use the membrane as a mouse closure if the diving body in the reservoir is embedded in a protective means for protection from corrosion and other environmental influences, as long as the inside of the reservoir is essentially seawater whirlpool and pressure compensation. Seems to be.

If a mouse closure is formed by the membrane, it is useful to envision a piston or cylinder in a piston-cylinder arrangement that moves against the membrane and breaks the membrane and releases an exit opening large enough for the diving body to eject. To ensure this, it is advantageous that the piston or cylinder moving against the membrane is coupled upon movement to at least one cutting tool that cuts the membrane before the diving body reaches the outlet opening. Preferably this cutting tool is arranged directly on the end of the piston or cylinder in contact with the cover.

The starting device for a diving body schematically shown in FIGS. 1 and 2 includes a storage container 2. The cross section of the storage container 2 is essentially infinite, but the storage container 2 is preferably designed in a tubular round manner. The storage container 2 serves to receive the submersible body 4 disposed in the storage container 2 in a mount not shown in the figure.

The end plate 6 is arranged on the end side of the storage container 2 in contact with the stern 18 of the diving body 4. This end plate 6 comprises an opening 7 into the interior of the storage container 2, in which the opening 7 can optionally be closed with a cover. The end plate 6 also includes a recess 8. The piston-cylinder arrangement 10 is guided through this recess 8 so that a part of this piston-cylinder arrangement 10 extends into the storage vessel 2. This piston-cylinder arrangement 10 consists of a cylinder 12 in which the piston 14 is guided in a movable manner. The cylinder 12 and the piston 14 guided in the cylinder 12 are disposed in the storage container 2 apart from and parallel to the diving body 4.

The cylinder 12 on the side in contact with the diving body 4 and in the portion disposed in the storage container 2 comprises an elongated slot which preferably extends to the distal side disposed in the storage container 2. A ring 16 disposed on the piston 14 is guided in this longitudinal slot and engages on the diving body 4 in the region of the stern 18.

The distal side of the reservoir 2 opposite the end plate 6 forms an outlet opening 20 for ejecting the diving body 4 from the reservoir 2. This outlet opening 20 is closed by a cover 22. This cover 22 is pivotally mounted on a joint 24 arranged on the outer side of the storage container 2, around a pivot axis A arranged in a plane common to the outlet opening 20. The pivot axis A is aligned transversely to the longitudinal extension of the piston-cylinder arrangement 10 and on the side of the piston-cylinder arrangement 10 apart from the submersible body 4. Placed away).

The piston 14 of the piston-cylinder arrangement 10 has a smaller distance with respect to the inside of the cover 22 than the head of the submersible body 4 whose protruding end from the cylinder 12 in the storage container 2 is. It is arranged in such a way as to have. In order to open the cover 22 in a low friction manner, the end of the piston 14 protruding from the cylinder 12 is designed in a round manner or has a rotating element, for example a roller or wheel.

If the submersible body 4 protrudes from the storage container 2, the cylinder chamber 26 located behind the piston 14 in the protruding direction of the submersible body 4 preferably collides with the pressure hydraulically. Subsequently the pressure force acting on the end face 28 of the piston 14 and defining the cylinder chamber 26 is coupled to the piston 14 as it moves through the ring 16 in the direction of the cover 22. The piston 14 is moved together with the body 4. The piston 14 contacts the cover 22 and the cover 22 to a position to release the outlet opening 20 of the storage container 2 before the diving body 4 reaches the outlet opening 20. Pivot. Subsequently, the piston 14 and the diving body 4 are completely ejected from the storage vessel 2. The cover 22 is in a position where the spring force given by the spring closes the outlet opening 20 after the piston 14 and the diving body 4 have passed by a spring not shown in FIGS. 1 and 2. It is biased in such a way that the cover 22 is moved again.

The embodiment of the starting device for the diving body 4 of the present invention shown in FIG. 3 for many components corresponds to the embodiment shown in FIGS. 1 and 2. For this reason, only the differences of the starting device according to FIG. 3 are discussed hereafter for the starting device according to FIGS. 1 and 2.

In the starting device shown in FIG. 3, the mouth closure closing the outlet opening 20 formed on the storage container 2 is formed by a membrane 30 over it and which completely closes the outlet opening 20. . Use of the membrane 30 as a mouse closure is possible as long as the free inner space of the storage container 2 is completely filled with liquid protection means, and the liquid protection means is preferably glycol. As a result, pressure balance in the membrane 30 occurs regardless of the submarine's diving depth.

The membrane 30 is broken to deploy the diving body 4. For this purpose, at least one cutting tool 32 is arranged at the end of the piston 14 'protruding from the cylinder 12, which cuts the membrane 30 by the outward movement of the piston 14'. Cut. 4-7 show a possible arrangement and design of the cutting tool 32 on the piston 14 '. 4 and 5 thus show a cutting tool 32 'disposed at the free end of the piston 14'. The cutting tool 32 'is disposed on the piston 14' in such a way that the cutting edge 34 'faces obliquely to the front in the ejection direction of the piston 14'. The cutting tool 32 'forms a tip 36' on the cutting edge 34 ', using which the membrane 32 is perforated and successively cut into the cutting edge 34' over a large length. Can be. 6 shows the placement of two cutting tools 32 ′ on the piston 14 ′. Here, the cutting edges 34 'are aligned obliquely with one another in a substantially V-shaped manner in the cross-sectional plane of the piston 14'. Finally, a cutting tool 32 "in the form of a triangular blade is shown in FIG. 7, wherein the tip 36" faces the ejection direction of the piston 14 ', and the cutting edges connecting to this tip 36 ". 34 ") is aligned obliquely with respect to this ejection direction of the piston 14 '.
