SURPLUS BUOYANCY ADJUSTMENT FLOAT

摘要

PROBLEM TO BE SOLVED: To provide a surplus buoyancy adjustment float adjusting surplus buoyancy by taking out and inserting granular weights into the main body case of a float, in which the granular weights are prevented from being dropped out and lost when the granular weights are taken in and out. SOLUTION: The granular weights are prevented from being dropped out by providing a cylindrical case which forms a part of the main body of a float and has space for holding a plurality of the granular weights and a divider having a through hole to become the doorway of the granular weights at one end or at the middle of the case. The storage part of the granular weights are made transparent to clarify the present number of the granular weights and surplus buoyancy is readily adjusted by providing the tip part of the float with a marking line for indicating the position of surplus buoyancy changing with the number of the granular weights.
