CONTROLLER FOR SETTING DIRECTION OF OBJECT TO BE SETTLED UNDER-WATER

摘要

PURPOSE:To easily and stably control the direction of an object to be settled in under-water area where the speed of tidal current is high by attaching a vertical rudder in an angle adjustable manner to a hanging frame to be vertically moved by a crane. CONSTITUTION:A hook 12a on the tip of the winding wire 12 of the crane 11 in a crane ship 10 is engaged with the hanging wire 2 of a hanging frame 1, and an object A1 to be settled is held by hanging by means of a hanging wires 4 on the downside of the frame 1. The object A1 is settled with the frame 1, and the direction of the frame 1 is measured by reading the values of a potentiometer and a declinometer. On the basis of the measured values, a rotator 7 is operated toadjust the direction of a vertical rudder 5 attached to the frame 1, and the direction of the object A1 is controlled toward desired directions. The object A1 to be settled in the sea area where the speed of tidal current is high can thus be easily and stably directed.
