Title:
FLOAT AND SINK TYPE SPAR BUOY AND ITS ACTUATING SYSTEM
Document Type and Number:
Japanese Patent JP3638497
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To dispose one fixed buoyancy body 2a and two variable buoyancy bodies 2b, 2b symmetrical with respect to it so as to sandwich a range pole body 1, by forming the buoyancy body 2 of a lead-in moored spar buoy by the one buoyancy body 2a and the variable buoyancy bodies 2b, while the both buoyancy bodies 2b, 2b are in communication with an air supply and exhaust line.
SOLUTION: If air is supplied to two variable buoyancy bodies 2b, 2b through an air supply and exhaust line form the land, they become inflated and surface from the fixed buoyancy body 2a side and stand erect. If the air is discharged by opening the valve of an air source on the land, the two variable buoyancy bodies 2b, 2b become defeated and gradually sink while being twisted so that the fixed buoyancy body 2a is above them, and reach the sea-bottom (g) so that the two buoyancy bodies 2b, 2b are below it.
