[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a long dozen observation buoy mooring lines in an ocean observation ship that inputs dozens of ocean observation buoys into the deep-sea area to perform ocean observation. The present invention relates to a mooring rope handling device that winds up.

[0002]

2. Description of the Related Art In conventional ocean observations, fixed point observations have been carried out by oceanographic research vessels, but since the number of such observations is limited, the observable sea area is limited. By the way, in recent years
With the understanding of the effects on the weather caused by sea elephants, marine pollution, and tidal currents that cause the El Niño phenomenon, the need for wide-ranging oceanic observations in wide open ocean areas has become necessary.

Therefore, when conducting ocean observation over a wide sea area, a buoy equipped with meteorological and ocean observation equipment is moored at a predetermined position,
For example, it is considered that a mother ship receives an observation signal emitted from the buoy for weather observation.

[0004]

However, the conventional observation vessels are limited in equipment and loaded with mooring ropes of up to 5000 to 6000 m and dozens of observation buoys that can be used even in deep water, and take them out in order. It was impossible to moor or recover it in the prescribed sea area.

The present invention solves the above problems and provides a marine observation vessel capable of winding and unwinding dozens of long mooring lines sequentially and safely and quickly, which contributes to wide-area ocean observation in the pelagic sea area. An object is to provide a mooring line handling device for an observation buoy.

[0006]

In order to solve the above problems, a mooring rope handling device for an observation buoy in an ocean observing ship according to the present invention is a winding device for winding a mooring rope composed of a resin rope and a steel rope. It consists of a drum and a mooring line handling device that can feed and wind the mooring line around the winding drum, and a resin rope core frame and steel A rope winding frame and a vertical axis are arranged on the same vertical axis, and a feeding device capable of feeding and hoisting the mooring line to the mooring line handling device, and a mooring line for guiding the mooring line from the feeding device to a winding drum. A guide device is disposed in the mooring line guide device, and a swivel arm that is rotatable above the housing case of the winding drum around the same vertical axis as the winding core frame and a feed device from the feed device to the axial center position of the swivel arm. Staff A guide hole for introducing the rope and a movable sheave for guiding the mooring rope, which is introduced into the turning arm through the guide hole, toward the winding drum are provided, and the movable sheave is moved in the longitudinal direction of the turning arm by the driving means. A position adjusting device is provided, and a turning drive device for rotating the turning arm at a predetermined speed is provided corresponding to the mooring line feed speed of the feeding device and the position of the movable sheave.

[0007]

In the above structure, the work of inserting the observation buoy is
Resin rope of winding drum Guide the resin rope wound on the core frame through the movable sheave and guide hole of the swivel arm, attach a sinker to the tip of the resin rope, and lower it into the sea by the feeder. .. Then, the steel rope connected to the resin rope is unwound from the steel rope winding frame like the resin rope. At this time, since the turning arm is rotated by the turning drive device in correspondence with the feed speed of the resin rope and the position of the movable sheave, that is, the winding radius of the resin rope, the mooring line can be smoothly unwound from the winding drum. it can. Also, for the recovery work of the observation buoy, the steel rope is introduced from the feeding device to the winding drum through the guide hole of the turning arm and the movable sheave, and the feeding device and the turning arm are driven to pull the steel rope. Around the steel rope core frame, the resin rope is wound around the resin frame in sequence. At this time, the swivel arm is rotated in accordance with the feed speed of the mooring line and the position of the movable sheave, that is, the winding radius of the resin rope, similar to the time of unwinding, so that the mooring line is smoothly wound around the winding drum. be able to. Moreover, since the resin rope and the steel rope containing a large amount of water can be wound on separate winding core frames, it is possible to prevent the water contained in the resin rope from adversely affecting the steel rope.
