Description

The invention relates to a submarine with an opening and a cover closing the opening, the cover being able to be rotated via a drive located on the axis of rotation of the cover.

For the purposes of the invention, an opening is understood to mean a connection between the interior of the submarine, in particular the interior of the pressure hull of the submarine, and the surrounding water area, the term opening also being able to encompass the wall which actually surrounds the passage space. The wall can be a tube, for example a weapon barrel, a multi-function barrel, a lock, a storage container, a person exit (LUK) and the like. In the case of a pipe, there is a storage space in its interior in which a weapon, for example a torpedo, equipment, divers or any other things can be stored. The tube can have a further opening to the inside of the pressure body, for example for a diving lock or for reloading a weapon barrel. In the case of a multifunction tube, a module can even be introduced, which is connected to the interior of the pressure hull of the submarine for the entire duration of the operation. However, a tube can also have only one opening, for example to accommodate items of equipment which, for example, should be removable by divers in the submerged state.

However, the higher the opening, the more important it is to reduce weight, otherwise the center of gravity of the submarine will be negatively affected. Accordingly, this is the most important if the opening is arranged in the tower, in particular at the upper end of the tower. The higher the center of gravity, the more unstable the submarine becomes.

Furthermore, the bearing points of the rods are in direct contact with sea water. Because of the thrust movement there, the danger of dirt being drawn in during the translatory movement is great. In addition, the cover with a push rod also has two pivot points, which are also exposed to the sea water. In order to keep them functional, two separate grease supply lines must be installed to ensure permanent operation.

The object of the invention is to provide an opening mechanism for a lid of an opening which, even when arranged high in a submarine, results in the least possible deterioration in stability.

This object is achieved by a submarine with the features specified in claim 1. Advantageous further developments result from the subclaims, the following description and the drawings.

The submarine according to the invention has at least one first opening between the interior of the submarine and the surrounding water area. The environment is water in the submerged state, but in the submerged state the opening can also be arranged above water. The first opening is connected to a first cover. The first opening can be closed with the first cover. The first cover is rotatably mounted about a first axis of rotation.

The submarine has a first first rotary drive and a second first rotary drive, the first first rotary drive and the second first rotary drive being arranged on the first axis of rotation. The first first rotary drive and the second first rotary drive are arranged on opposite sides of the first cover of the first axis of rotation. The first first rotary drive and the second first rotary drive are designed to rotate the first cover about the first axis of rotation and for this purpose are connected to the first opening and the first cover.

The arrangement of two rotary drives on the axis of rotation achieves two essential things. On the one hand, only control lines have to be routed to the rotary drives. The hitherto common linkage and hydraulic cylinders are no longer required, thus significantly reducing weight. The disadvantage is that the first first rotary drive and the second first rotary drive are not located inside and are therefore exposed to the ambient conditions, in particular sea water, which is why such an arrangement has been avoided to date. However, the increase in stability has proven to be advantageous.

When using a rotary drive, there is only one sealing point on a rotary drive, which lies between the housing and the rotating shaft. This reduces the places where sea water can attack. The rotary drive can be designed both hydraulically and electrically.

In a further embodiment of the invention, the normal to the first opening has an angle of less than 45 ° to the vertical, the vertical being arranged at right angles to the longitudinal axis of the submarine. The normal of the first opening preferably has an angle of less than 15 ° to the vertical, particularly the longitudinal direction of the first opening is preferably arranged vertically.

In a further embodiment of the invention, the submarine has a tower, the first opening being arranged in the region of the tower.

In a further embodiment of the invention, the first first rotary drive is connected to the first cover via a first first clutch and the second first rotary drive is connected to the first cover via a second first clutch. This embodiment is advantageous in order to separate it in the event of a failure of a rotary drive, so that the other, still functional rotary drive does not also have to exert the force to rotate the defective rotary drive.

In a further embodiment of the invention, the hydraulic rotary drive is designed such that the first first clutch is also supplied via the hydraulic circuit of the drive. If the drive fails and the hydraulic circuit is short-circuited as a result, the hydraulic pressure at the first first clutch drops and the clutch is disengaged. A central shaft preferably connects the cover axis of rotation to the rotary drive, with no holding torque being maintained. This allows the lid to rotate freely.

In a further embodiment of the invention, the cross-sectional area of the first opening lies in a first plane, the axis of rotation lying in the first plane.

In a further alternative embodiment of the invention, the cross-sectional area of the first opening lies in a first plane, the axis of rotation being arranged above the first plane.

In a further embodiment of the invention, the first opening has a first press ring for locking the first cover, the first press ring having an outlet in the region of the first axis of rotation.

In a further embodiment of the invention, the first first rotary drive is driven hydraulically, pneumatically or electrically and the second first rotary drive is driven hydraulically, pneumatically or electrically. In the case of a hydraulic drive with hydraulic oil, the hydraulic oil can also take over the lubrication function. Servomotors are preferred for electrically operated drives.

In a further embodiment of the invention, the first axis of rotation is arranged in the longitudinal direction of the submarine. This arrangement has proven to be advantageous for opening the lid when driving in the submerged state.

In a further embodiment of the invention, the submarine has at least one second opening to the surroundings, the second opening being connected to a second cover, the second opening being closable with the second cover. The second cover is rotatably supported about a second axis of rotation. The submarine has a first second rotary drive and a second second rotary drive, the first second rotary drive and the second second rotary drive being arranged on the second axis of rotation. The first second rotary drive and the second second rotary drive are arranged on opposite sides of the second cover of the second axis of rotation. The first second rotary drive and the second second rotary drive are designed to rotate the second cover about the second axis of rotation and are connected to the second opening and the second cover for this purpose.

Of course, a submarine can also have more than two openings with opening mechanisms according to the invention.

In a further embodiment of the invention, the first opening and the second opening are arranged one behind the other in the longitudinal direction of the submarine and the direction of rotation of the first cover and the direction of rotation of the second cover are opposite.
