Abstract
The mast device for a submarine comprises a guiding means, a vertically traversable mast guided therein and information means which are provided at the mast upper end and which are in electrical interaction with the inside of the submarine for emitting and receiving information. The information means are arranged in a buoyant unit held on the mast upper end without connection to this. The buoyant unit is fastened to a flexible coupling means which may be let out and retracted and which is of the length essentially of the maximum desired observation depth of the submarine.
Claims14
A mast device for a submarine, comprising a guiding means, a mast guided thereon and being vertically extendable and retractable into and out of a tower of the submarine and information means which are provided at the mast upper end and which are in electrical interaction with the inside of the submarine for emitting and receiving information, wherein the information means are arranged in a buoyant unit held on said upper end of said mast without connection to said upper end and wherein said buoyant unit is fastened to a flexible coupling means which may be let out and retracted and which is of the length essentially of the maximum desired observation depth of the submarine.
A method for increasing an observation diving depth of a submarine, comprising the steps of:
- providing a buoyant unit comprising information means coupled to said submarine with a flexible coupling;
- providing a mast that is vertically extendable and retractable into and out of the submarine;
- extending the mast out of the submarine;
- releasing said buoyant unit from a mast when it is desired to communicate;
- letting out said flexible coupling in a length that substantially corresponds to said observation diving depth.
A mast device for a submarine, comprising a guide comprising a vertically traversable mast guided thereon so that it is vertically extendable and retractable into and out of the submarine and information means which are provided at an upper end of the mast and which are in electrical interaction with the inside of the submarine for emitting and receiving information, wherein the information means is arranged in a buoyant unit held on the mast upper end and wherein the buoyant unit is fastened to a flexible coupler which may be let out and retracted and which may be let out to a length essentially of the maximum desired observation depth of the submarine;
- said buoyant unit being held on said upper end of said mast when it is not let out, being releasable from said upper end when it is let out, and being retractable back to said upper end when it is retracted.
