Description

Es sind bereits Vorrichtungen zum Anzeigen des Offen- oder Geschlossenseins der Kontakte des Zündstromkreises von Seeminen oder anderen, ins Wasser zu versenkenden, mit elektrisehen Einrichtungen beliebiger Art versehenen Körpern bekannt geworden, bei denen der Stromschluß in bestimmter Wassertiefe durch den auf eine Membran wirkenden Wasserdruck bewirkt wird.There are already devices for indicating whether the contacts are open or closed of the ignition circuit of sea mines or other, to be submerged in the water, with electric view Facilities of any type provided bodies become known in which the Electricity short-circuit in a certain water depth due to the water pressure acting on a membrane is effected.

ίο Der Gegenstand der Erfindung ist eine Vorrichtung dieser Art, bei eier jedoch auf der Membran ein unter schwacher Federwirkung stehender Kolben aufruht, der sich mit der Membran bewegt und dessen anderes Ende aus dem Minengehäuse herausragt und durch die Länge des herausragenden Stückes anzeigt, ob der Kontakt geöffnet oder geschlossen ist.ίο The subject of the invention is a device of this type, but with eggs on the membrane a weak spring action standing piston rests, which moves with the diaphragm and its other end protrudes from the mine housing and indicates by the length of the protruding piece, whether the contact is open or closed.

' Dabei kann mit dem Kolben ein Schwimmer verbunden sein, der sich Von dem Kolben selbsttätig ablöst und hochsteigt, wenn die Membran ihre tiefste, den Kontakt schließende Lage erreicht hat.'A float can be connected to the piston, which floats from the piston automatically detaches and rises when the membrane is at its deepest point, which makes contact Has reached.

Auf der Zeichnung ist eine beispielsweise Ausführung der Erfindung dargestellt.An example embodiment of the invention is shown in the drawing.

α ist die Wand des wasserdichten Auftriebraumes des Schwimmkörpers, z. B. der Seemine, an dessen oberen Seite eine kreisförmige Öffnung vorgesehen ist, in die in bekannter Weke ein mit einem Gewinde und Dichtungsmaterial versehener Ring b eingesetzt ist. In diesen Ring b kann die Entschärfereinrichtung als ganzes Stück wasserdicht eingeschraubt werden. Der Apparat selbst besteht aus dem oberen und unteren Teil, welche durch die bewegliche Membran c wasserdicht voneinander getrennt sind. ' Letztere wird durch eine starke, mittels einer Stellmutter d auf einen bestimmten Druck einstellbare Schraubenfeder e nach außen gedrückt, wodurch die mit der Membran c starr verbundene, obere Kontaktplatte f von der unteren Platte g entfernt wird. Die untere Kontaktplatte g ist an dem durchbrochenen Gehäuse des Entschärfers mittels versenkter Schrauben o. dgl. befestigt. Von beiden Kontaktplatten f und g gehen Leitungsdrähte isoliert durch den Boden des Apparates. Der obere über der Membran c angeordnete Teil des Apparates schützt mit einer schwach gewölbten, für den Wasserzutritt durchbrochenen Decke h zunächst die Membran gegen mechanische Be-Schädigungen. Zentral in der Mitte der Decke h ist ein beweglicher hohler Kolben i angeordnet, welcher mit einer gewölbten Bodenplatte k sich gegen die Membran c legt. Durch eine kleine Schraubenfeder I, welche, zwischen dem gewölbten Boden k des Kolbens i und der Ab- α is the wall of the watertight buoyancy space of the float, e.g. B. the sea mine, on the upper side of which a circular opening is provided, into which a ring b provided with a thread and sealing material is inserted in a known manner. In this ring b , the defusing device can be screwed watertight as a whole piece. The apparatus itself consists of the upper and lower parts, which are separated from each other by the movable membrane c in a watertight manner. The latter is pressed outwards by a strong helical spring e which can be adjusted to a certain pressure by means of an adjusting nut d, as a result of which the upper contact plate f rigidly connected to the membrane c is removed from the lower plate g. The lower contact plate g is attached to the perforated housing of the defuser by means of countersunk screws or the like. From both contact plates f and g , lead wires go insulated through the bottom of the apparatus. The upper part of the apparatus arranged above the membrane c protects the membrane against mechanical damage with a slightly curved cover h which is perforated for the access of water. Centrally in the middle of the ceiling h is a movable hollow piston i , which with a curved base plate k rests against the membrane c . By a small helical spring I, which, between the curved bottom k of the piston i and the ab-

As long as the membrane c is not pressed inwards by the water pressure, its strong helical spring e overcomes the force of the weak spring I of the piston i, the latter remaining in its upper position and protruding about 7mm over the edge of the housing: it . The piston i owns. in its interior a tulip-like locking spring m for a correspondingly designed pin "of the float 0. The latter is, as can be seen from the figure, inserted from above with its pin η in the cylinder piston i that it is fixed by the locking spring m. is held, which, the latter is held so strong that it overcomes the buoyancy of the swimmer when submerged and holds it. The amplitude of the membrane c is dimensioned such that when the spring force e is overcome by the external water pressure, the contact is closed by the plates f and g lying one on top of the other and the cylinder piston i following the membrane moves down so far that the small locking spring m over the groove of the floating pin η slides so that the float 0 itself is no longer held. The application and mode of operation of the subject matter of the present invention is as follows: Before the disarming device is inserted into the float, the diaphragm spring e is tensioned by the adjusting nut d in such a way that the water pressure overcomes the tension force of the spring e at the desired specific immersion depth. After the disarming device has been inserted, the float 0 is pressed with its pin η into the locking spring m of the cylinder piston i. As long as the float is in the air and also initially when submerged, the spring pressure of the locking spring e will push the membrane c outwards, whereby the float 0 is held and the electrical contact remains open. When the floating vessel reaches the prescribed depth, the water pressure will push the membrane c inwards, overcoming the spring force e, close the contact and at the same time release the float 0, which rises to the surface of the water by virtue of pure buoyancy. The float can be designed in various ways, z. B. provided in a known manner with smoke or flames developing facilities and connected to the under 'water body by a wire or rope.
