Drop assist apparatus of unmanned marine observation apparatus and controlling method thereof

An apparatus for assisting in dropping an unmanned marine observation device, the apparatus comprising:

• a support part installed on a ship;
• a column part installed to be movable in a horizontal direction relative to the support part;
• a first link member having one end linked to an upper side of the column part;
• a second link member having an end linked an other end of the first link member;
• and
• a holding unit installed on the second link member by a first rail formed in the second link member so as to be movable in a longitudinal direction of the second link member and be rotatable about a rotation axis perpendicular to the longitudinal direction of the second link member,
• wherein the holding unit is configured to hold an outer periphery of the unmanned marine observation device, and be provided to be adjustable to prevent interference with a guardrail of the ship when the unmanned marine observation device held by the holding unit passes over the guardrail of the ship by rail movement and rotation with respect to the second link member and to prevent a position or a posture of the unmanned marine observation device from changing,
• wherein the support part comprises a rail part coupled to a lower side of the column part by a second rail formed in the rail part so that the column part is movable in the horizontal direction,
• wherein the rail part is provided to allow the column part to move along the rail part so that the second link member is selectively positioned at any one of inner and outer sides of the ship, and maintain a safety distance from the guardrail when the second link member is positioned at an inner side of the ship, and
• wherein the column part is extendable and contractible in an upward/downward direction in consideration of height adjustment for dropping the unmanned marine observation device from the height of the ship having a variable height and height adjustment to prevent the guardrail of the ship from being damaged.
