After that it turns on its free end connected to the underwater vehicle Connection cable unwound from the take-up drum and drawn from the underwater vehicle.
• This known outlet device has the disadvantage that for Lowering and hauling in the heavy discharge weight using a crane is required and therefore a lot of space must be held up to the foredeck. That into the water immersed discharge weight brings through its unfavorable Flow behavior with considerable energy losses.
• this outlet device is not suitable in the much cheaper for work on deck because protected and less vulnerable, rear area installed to be because the connecting cable through the Propeller and vice versa the propeller through the Connection cable is extremely at risk.
• the device is equipped with a yoke. Of the Boom carries a lead head made of two mouths trained head areas. When pulling the pulls Winch with the tow rope the towing device over a Rope pulley and guide pulley as well as over the guide head of the Boom up to its end position.
• To suspend the The towing device is by pulling the tow rope
• the boom is pivoted downwards until the guide head is in the Water immersed. If the surface ship picks up speed, so the tow body pulls the tow rope over the Pulley from the approved winch.
• the invention has for its object a To create outlet device of the type mentioned at the outset, which a removal and insertion of the connecting cable from Rear area out with no risk of collision with the Allows propeller, and beyond is lightweight, so that no additional, ship-side, motorized lifting tools, the require additional installation space are necessary.
• the outlet device has the advantage that through the rigid protective pipe, the pipe mouth below the propeller, it is ensured that the connecting cable at no time its Fishing, catching up or staying in the water can come into contact with the propeller.
• the protective tube can be brought out in the Horizontal are locked and thereby holds that Connection cable far from the ship's stern and thus from the Propeller.
• the free tube end of the protective tube is curved so that the axis of the tube mouth is approximately perpendicular to the tube axis and the tube mouth points in the direction of the propeller.
• This end region of curvature is preferably realized by articulated pipe segments which are lined up in the longitudinal direction of the protective tube.
• the protective tube is at least limited about its longitudinal axis rotatable.
• the protective tube is in the Position, with lateral flow by rotation around its Longitudinal axis to lie in the flow and only one to create little resistance in the water.
• the protective tube is designed to be deflectable to a limited extent. Because of this lateral deflection of the protective tube, what preferably by an elastic definition of the Deflection device facing the pipe end on the ship deck is realized on the protective tube by rolling the Vessel or side forces caused by the flow balanced.
• the protective tube is at its the deflection device the facing end of the pipe can be quickly dismantled fixed. This makes it possible to temporarily not using the protective tube together with the cable section guided in it lengthways on the Store ship deck.
• the protective tube made of two form-fitting tube shells composed, which are firmly together, e.g. by clips or screws.
• This constructive Forming the protective tube gives the possibility, e.g. at the Replacing the connecting cable the cable from the Take out the protective tube without the existing ones Connector for connecting the cable to the Underwater vehicle and to the ship's side Disconnect the supply unit from the supply cable have to.
• Fig.1 is a surface ship with 10 and 11 with Underwater vehicle referred to in the embodiment is used as a mine hunter to 12 to locate, classify, and lay mines 13 identify and destroy. That as a mine hunt boat designated surface ship 10 is suitable for this purpose electronic components equipped in one Operations center are summarized and dated Data sent underwater vehicle 11 accordingly process and appropriate control commands to the Send underwater vehicle 11.
• the underwater vehicle 11 is equipped with its own drive and is operated by Operations center in the surface ship 10 controlled.
• the underwater vehicle 11 is connected via a connecting cable 14 tied to the surface ship 10. About the Connection cable 14 takes place both the energy supply of the underwater vehicle 11 as well as the data exchange between the electronic components of the Surface ship 10 and the underwater vehicle 11.
• the underwater vehicle 11 is moved from Aft deck 101 of the surface ship 10, which turns out to be Working platform has proven to be the most appropriate. Either the insertion of the underwater vehicle 11 into the water as also the lifting of the underwater vehicle 11 from the Water takes place by means of one on the aft deck 101 arranged lifting crane or davits 15, as shown in Fig.2 see is.
