Coupling device for recovering unmanned ship and coupling control method using same

Abstract

The present invention relates to a coupling device for recovering an unmanned ship and a coupling control method using the same, the coupling device comprising: a coupling unit, which is lifted and lowered by being connected to a crane provided in a mother ship, and is formed to be long such that one side thereof selectively protrudes expansively along the circumference thereof; an accommodation unit provided in the unmanned ship, and having a vertically communicating coupling hole such that at least a portion of the coupling unit is inserted therein; a guide unit performing guiding such thatthe coupling unit is coupled to the accommodation unit, and including a towing line formed to be long so as to be coupled to the coupling unit in a state in which one side thereof passes through the coupling hole, and a winch connected to the other side of the towing line so as to selectively wind or unwind the towing line; and a control unit including a sensing part for sensing the tension applied to the towing line by the driving of the winch, and a control part for lowering the coupling unit connected to the crane, if the intensity of the tension sensed by the sensing part is a preset valueor higher, wherein the control part lowers the coupling unit in correspondence to the length of the towing line wound by the winch, when the coupling unit is lowered, such that the coupling unit is coupled to the accommodation unit.

Description

technical field [0001] The present invention relates to a connection device for recovering an unmanned boat and a connection control method using the same. A connecting device for recovering an unmanned boat that is connected to a connecting device of a mother ship so that the connecting device is connected to an unmanned boat, and a connection control method using the same. Background technique [0002] With the development of unmanned technology, unmanned boats used to perform operations that are dangerous and inefficient for manned ships in existing offshore operations such as marine surveys, marine reconnaissance and surveillance, and marine accident response development is actively in progress. [0003] When using unmanned boats in the sea, the method used is to load the unmanned boats on the mother ship and run the unmanned boats to perform tasks when necessary. After the mission is completed, the unmanned boats are recovered to the mother ship. This method can reduc...

Problems solved by technology

[0005] However, when recovering the unmanned boat using a crane equipped with the mother ship, etc., it is necessary to connect the cable connected to the crane to the unmanned boat, but since the unmanned boat does not carry the crew, it is necessary for the crew to move from the mother ship to the unmanned boat. It is necessary to connect the cable or use the hook to connect the unmanned boat, but there is a problem that it is difficult to work in the sea with high waves

That is, there may be a safety accident when the crew moves to the unmanned boat to connect the cable
